Oleg Isonen a6a9049399 fix: validate published MDX before publish (#6468)
## Related issue

Related to #3550.

## Summary
- Run the existing published-MDX materializer during pre-publish
validation and surface its error diagnostics before starting dynamic or
static publishing.
- Reuse the dependency walk that builds the publication artifact to
limit validation to reachable Content Blocks, including blocks whose
asset is missing.
- Add actionable fix hints for unavailable MDX assets and invalid HTML
nesting.
- Show a compact error/warning count in the publish dialog, with a
details dialog that has counted Errors and Warnings tabs and hides empty
tabs.
- Include relevant IDs and navigation links in reports when available,
with guidance when they are not; allow users to copy all reports and
select the text.
- Resolve missing-document IDs against loaded asset metadata and show
the filename and Content Assets folder path when available.

The page-tree pre-publish audit already checks HTML content models, but
it cannot see content generated from MDX assets. This extends preflight
to that content using the same materializer and diagnostics as the
publish build. It also catches unavailable MDX assets before the publish
job starts.

## Plan and status

### Implemented
- [x] Reuse existing publish-time MDX discovery and materialization so
preflight checks the content that will be published.
- [x] Collect every page-tree audit error and warning, not only the
first finding for each severity.
- [x] Collect every MDX publish error and provide a location and
remediation hint.
- [x] Collect missing or ambiguous template warnings and
content-database omission warnings.
- [x] Show a compact error/warning total in the publish dialog.
- [x] Add a details dialog with standard panel padding, spaced and
separated findings, and counted Errors and Warnings tabs; hide empty
tabs.
- [x] Copy all reports from the dialog header and allow report text
selection.
- [x] Include diagnostic codes and relevant instance, asset, document,
and resource IDs in reports.
- [x] Keep “See issues” visible in the narrow publish panel.
- [x] Keep element navigation available from page-tree audit findings
and link content findings when the target is available.
- [x] Use the same findings UI for dynamic and static publishing.
- [x] Block publishing on errors and allow warnings to proceed.
- [x] Keep unexpected preflight failures visible to the user.
- [x] Show a preflight failure either in the open publish dialog or in a
toast when the dialog is closed, avoiding duplicate reports.
- [x] Replace opaque “Document … could not be loaded” errors with
actionable guidance, including the asset filename and folder path when
available.

- [x] Load linked document sources during MDX validation and prebuild
when they are absent from the compact content artifact.

### Regression checks completed
- [x] No-findings validation preserves the normal publish path.
- [x] Single and multiple findings show accurate totals and details.
- [x] The “See issues” action is visible in the publish panel and opens
diagnostics.
- [x] “Show element” navigation remains wired to the affected element
and closes the publish dialog.
- [x] More than five MDX errors and more than ten missing-template
warnings remain available in diagnostics.
- [x] Mixed MDX errors, audit errors, template warnings, and database
warnings are combined and counted.
- [x] Errors stop dynamic and static publishing; warnings do not block
publishing.
- [x] Error-only, warning-only, and mixed states show the right tabs and
counts, with empty tabs hidden.
- [x] Copy-all includes every error and warning with context, and report
text is selectable.
- [x] An open dialog receives inline preflight failures without a toast;
a closed dialog receives a toast without a duplicate inline report.
- [x] Missing-document errors include filename/folder context when
available and useful fallback guidance when metadata is unavailable.

- [x] Reproduce the linked-author failure with the affected project’s
hosted build, then confirm it builds successfully with the fix.

Oleg Isonen 6044792b77 docs: Explain Radix force-mount animation requirements (#6471)
## Summary

Document the animation constraints around Radix `forceMount`: closed
content remains mounted and needs explicit closed-state CSS, while Radix
suppresses CSS transitions and animations during height measurement, so
the first opening may not animate.

Updated Accordion and Collapsible docs, custom prop descriptions, and
generated prop metadata so the guidance appears in component discovery.

Closes #6197.

## Checks

- [x] Accordion and Collapsible documentation updated
- [x] Generated prop metadata refreshed
- [x] Package typecheck
- [x] Targeted Collapsible tests

Oleg Isonen 8a46350c9a fix: Compile MDX Content Blocks in hosted builds (#6455)
Hosted MDX pages can publish successfully and then fail to render
because the publish runner skips their source files. Restore source
downloads and compilation for MDX Content Blocks, including dynamic
article queries and template dependencies.

Reuse the existing publication planner and local content compiler.
Markdown-only pages keep their bodies on demand; hosted MDX pages
download article sources and pay the necessary compilation cost in the
runner, not the publish API. Reject missing content databases and MDX
materialization errors instead of deploying an incomplete page.

Ref #6450
Ref #6454

## Checklist

- [x] Reproduce missing MDX content using the affected deployed build.
- [x] Restore hosted MDX compilation without duplicating the
static-export compiler.
- [x] Add a sync → compile → generated query → React server-render
regression with a metadata-only API bundle and a frontmatter-bound
Content Block.
- [x] Verify new regression checks fail without the required behavior
and pass with it.
- [x] Reject missing MDX sources and content databases; preserve remote
article bodies when no MDX Content Blocks need compilation.
- [x] Review documentation impact and update the Content Engine
publishing explanation.
- [x] Run CLI tests, typecheck, lint, formatting, and package-boundary
checks.
- [x] Run the full fixture link/sync/build pipeline; no generated
changes.
- [x] Rebuild the affected project locally and exercise its generated
production request handler: HTTP 200 with the article title and body.
Asset requests were served from synced local files.

The live project was not modified or republished. Its existing
title/description bindings still use an array access for a single-result
query; that separate project-data issue is not changed here. Agent
evaluations were not run. Affected sites need republishing after the
updated CLI artifact is deployed.

Oleg Isonen 9b1100f25b fix: Restore hosted Assets queries (#6454)
Hosted Assets queries started returning 502 in 0.301.0 because publish
sync omitted their query database. Restore that database for hosted
builds while keeping Markdown body-reference queries on demand. Static
exports still prepare their database in the build runner.

Reject builds with Assets queries but no database before changing
generated files, so this failure cannot silently produce another broken
deployment or erase the previous generated output. Uses the existing
shared query compiler; no MCP-specific logic or API schema changes.

Closes #6450
Ref #6427

Replaces #6453 with the same commits on `assets.staging`, which matches
the staging deployment branch policy.

## Checklist

- [x] Reproduce the reported 502 and verify the fix on project and
custom origins.
- [x] Preserve static export behavior and on-demand Markdown loading.
- [x] Add a regression test for rejecting missing databases; demonstrate
failure before the fix and success afterward.
- [x] Review documentation impact and update the Content Engine
publishing explanation.
- [x] Run relevant tests, Builder/CLI typechecks, lint, formatting, and
package-boundary checks.
- [x] Run the full fixture link, sync, and build pipeline against the
patched preview API. Regenerate all eight JSON snapshots with the
current formatter; parsed data is unchanged and generated application
files are unchanged.

Validation: 88 CLI tests, 22 Builder tests, and four no-body-read
publication tests pass. Fixture size checks were unavailable without
compiled app bundles. Agent evaluations were not run. Existing affected
sites need republishing after the fix is deployed.

Oleg Isonen d78e770d82 perf: Keep article indexing out of publish API requests (#6427)
Ref #6416

The publish workflow was doing too much work in one short-lived API
request. This moves content indexing into the build runner and keeps
article bodies out of hosted/SSR sync.

## What changed

- The build-bundle API can return the lightweight project bundle without
preparing a full content index.
- The CLI downloads required assets directly from storage and builds the
index locally for SSG. Asset downloads remain bounded to 10 concurrent
requests.
- Hosted/SSR sync skips Markdown and MDX article downloads and does not
compile an article index. It still downloads regular assets needed by
the build.
- Markdown body queries use stored frontmatter and fetch only the
requested article at runtime. MDX still needs source downloads and
compilation for SSG.
- Public MCP and content-engine docs explain the Markdown/MDX tradeoff.

This removes article parsing and article-body transfer from the tRPC
request. SSG still downloads article sources from storage and compiles
MDX in the build runner. Hosted runtime article reads remain on demand.

## Checklist

- [x] Keep the tRPC bundle request limited to project metadata and
necessary records.
- [x] Prepare SSG content indexes in the build runner; keep hosted
article bodies out of sync.
- [x] Cover no-body query preparation, direct asset reads, and
SSG-versus-hosted sync behavior with regression tests.
- [x] Update public CLI, MCP, and content-engine guidance.
- [x] Regenerate and verify fixtures.
- [x] Run workspace tests, typechecks, lint, formatting,
package-boundary, generated API/docs, and fixture-size checks.
- [ ] Verify the deployed publish flow has comfortable margin below the
hosted API timeout.

## Verification

- `pnpm -r --workspace-concurrency=1 test`: passed, including all 3,082
Builder tests and 1,150 CLI tests.
- `pnpm -r typecheck`, `pnpm lint`, `pnpm check:package-boundaries`,
`pnpm check:generated-api`, `pnpm check:generated-docs`, `pnpm
check:fixture-sizes`, and `pnpm exec oxfmt --check`: passed.
- The new hosted article-download regression test was confirmed to fail
with the old behavior and pass after the fix.
- A deployed end-to-end publish timing check is still needed, so this PR
remains draft.

Oleg Isonen a4c3b37fc2 fix: Unblock reported MCP workflows and improve issue diagnostics (#6438)
## What this fixes

MCP authors can reuse an existing design token in JSX fragments, create
valid border shorthands with CSS variables, and bypass a font that never
settles during responsive screenshots. Common fixed page titles with
spaced separators are also accepted. Issue reports now include the
project ID and safe, bounded IDs from the failed operation, plus clearer
response and browser-startup diagnostics.

## Scope and tradeoffs

- `token("name")` attaches an existing design token; an unknown name
returns a not-found error. Empty token definitions from Builder/UI
remain definitions and follow the normal conflict rules.
- Border shorthands map a single unresolved `var()` to the remaining
width, style, or color field when the other fields are explicit.
- `waitForFonts: false` skips font readiness but still waits for stable
layout frames. The default remains unchanged.
- Fixed titles such as `Pricing - Plans` stay literal. Addition such as
`first + second` remains an expression. Wrap ambiguous subtraction in
parentheses, for example `(first - second)`. Other ambiguous title forms
may still need an exact report.
- Only recognized operation-level IDs are attached to a public GitHub
issue. Authored values, raw arguments, URLs, and credentials are
excluded. IDs from later successful diagnostic reads are not captured.
- This does not fix the underlying response-transform failure; it
improves future reports for that case.

Closes #6424
Closes #6425
Closes #6434
Closes #6439
Ref #6435
Ref #6430
Ref #6417

## Verification

- [x] Reproduced the privacy, page-expression, empty-token, and
content-mode token-reference regressions with failing tests, then
confirmed the fixes pass. A regression test also covers parenthesized
subtraction.
- [x] Full protocol, template, vision, project-build, and CLI test
suites pass; focused Builder issue-report and fragment tests pass. The
protocol, CLI, and project-build suites were rerun after the CI fix.
- [x] Relevant package typechecks, lint, package-boundary check, fixture
pipeline, generated API check, and generated docs check pass. Fixture
output has no diff.
- [x] Reviewed the authoritative MCP documentation and regenerated the
API metadata and MCP docs.
- [x] CSS parser regressions cover border, each side shorthand, and
unresolved variables in width, style, and color positions; css-data
tests, typecheck, and lint pass.
- [x] Fixed the local evaluation runner to pass the task and Webstudio
MCP tools to Luna/low. Each of the six fixtures passed at least once;
focused MCP/evaluator tests, CLI and project-build typechecks, lint, and
formatting pass.
- [x] The complete Luna/low suite passed all six fixtures in two
consecutive sequential runs. Baselines remain incompatible with this
model/effort override and were not updated.

## Follow-up

- If another fixed-title form still fails, use the new project-level
report context and the exact title shape to narrow the parser case.

Oleg Isonen 2c9fd16689 feat: configure custom response headers by route (#6429)
## Description

Project Settings starts with an empty response-header rule list. Users
can add valid HTTP response headers for all paths (`/*`) or an
Authentication-style route such as `/private/*`, and remove any
configured rule. The Headers and Authentication views share the
accessible rule-list form. The header form suggests standard
response-header names and common values for the selected header, while
accepting custom names and values. `Set-Cookie` is not suggested because
a rule can store only one value per header and would replace existing
cookies.

`X-Powered-By`, `X-Content-Type-Options`, and
`Strict-Transport-Security` are dispatcher-owned and cannot be
configured. Users may configure `Content-Security-Policy`,
`X-Frame-Options`, and `Referrer-Policy`; when absent, the dispatcher
supplies their defaults. The SDK validates header names, values, routes,
duplicates, and size limits. The CLI emits only configured rules.

Customization requires Pro for custom-domain publishing, while unchanged
defaults and staging remain available on Free plans. The server checks
the saved production snapshot against the project owner's plan.

Companion Cloud worker PR:
https://github.com/webstudio-is/webstudio-saas/pull/664. Deploy its
dispatcher support before exposing these settings in the Builder. Other
hosts need an adapter that applies the generated rules; Webstudio Cloud
dispatcher defaults do not apply automatically elsewhere. Static exports
do not apply headers automatically.

## Validation

- SDK, CLI, Builder browser, publish-warning, and production-build tests
pass.
- Builder, SDK, and CLI typechecks and lint pass.
- The companion Cloud worker tests, typecheck, and lint pass.

Replaces https://github.com/webstudio-is/webstudio/pull/6428 to use
`headers.staging`.

Oleg Isonen 3d0a0657aa feat: Support async resource dependencies (#6030)
## Summary

Make `Resource<Document>` the lazy document-resolution abstraction
shared by Content Engine graphs, generated sites, and Builder previews.
Expressions use one async computation interface: referenced resource
documents resolve first, independent requests run concurrently, and
unused resources stay unloaded.

Ref #6029
Ref #6031

## Implementation checklist

- [x] Define one resource contract for synchronous or asynchronous
document resolution.
- [x] Resolve explicit roots lazily with memoization, bounded
concurrency, cancellation, and structured errors.
- [x] Preserve cycle, duplicate, and missing-resource diagnostics.
- [x] Extract resource dependencies with the existing expression AST.
- [x] Discover consumed resource roots from the current page tree and
page metadata.
- [x] Generate a lazy request graph for published page data, including
independent requests.
- [x] Resolve dependency documents before evaluating dependent request
expressions.
- [x] Integrate dependency-first loading with Builder preview caching
and invalidation.
- [x] Expose safe Resource bindings in the editor and reject
self/indirect cycles.
- [x] Adapt REST, GraphQL, Assets, date, and sitemap requests through
the same Resource contract.
- [x] Cover laziness, chains, shared dependencies, concurrency,
invalidation, cancellation, failures, and cycles with fail/pass tests.
- [x] Review documentation impact and document dependent Resources in
the Data variables guide.
- [x] Track collection-item and component-parameter-dependent resources
as follow-up #6031.
- [x] Regenerate and review affected fixtures.
- [x] Resolve action-resource request dependencies when an action is
invoked.
- [x] Reproduce and fix cached form submissions and multi-root
dependency-cycle hangs.
- [x] Document uncached form actions and regenerate affected fixtures.
- [x] Preserve single and multi-selected content until a cut
successfully writes to the clipboard.
- [x] Preserve boolean expression values in the search-exclusion
checkbox.
- [x] Cancel cut deletion if project data changes while preparing or
writing the clipboard; cover content/property edits and project switches
for single and multi-selection, and document the retry behavior.

- [x] Validate pending cuts after the final await, immediately before
deletion, and reproduce the queued-update race for single and
multi-selection.

## Technical direction

The persisted, revisioned `DocumentGraph` remains the Content Engine
artifact. `Resource<Document>` is the execution abstraction for
obtaining a document; its resolver evaluates only the dependency closure
reachable from requested roots. Static and remote documents therefore
differ by Resource implementation, not by expression value type.

Generated pages always emit a `ResourceRequestGraph`. Each node owns its
output name, dependencies, and request factory. Roots come from resource
variables actually referenced by the current page's metadata, props,
actions, or expression children. Unused and off-page resources remain
unresolved. The loader still accepts legacy request maps for
compatibility.

Builder preview uses the same page-root discovery as published
generation. Its existing cache remains the lifecycle boundary: cached
dependency documents unlock dependent requests, while invalidation
removes downstream requests until their inputs resolve again. The
separate canvas frame recomputes its local plan from the synchronized
cache so rendered expressions receive those documents.

Action requests and their dependencies resolve when a form is submitted.
Each submission sends a new action request, bypassing Webstudio's
resource cache. Dependency requests still use their configured cache
lifetime.

## Review simplifications

- Consolidated page resource-root discovery in the SDK and reused it in
Builder.
- Scoped root and action discovery to the current page tree.
- Removed the redundant immediate-resource helper; `Resource.resolve`
already accepts `Document | Promise<Document>`.
- Moved output names onto graph nodes and removed the duplicate
graph-level map.
- Removed unused planner output and corrected transitive cycle discovery
to include only Resource data sources.
- Regenerated fixtures so independent resources also use lazy graph
execution.
- Reused one abort-aware concurrency limiter for document sessions and
Resource resolution.
- Collapsed duplicate generator action scans and removed redundant
generated-resource bookkeeping.
- Unified legacy request maps and request graphs through one resolution
path.
- Shared the 20-request concurrency limit between SDK, Builder preview,
and the server batch boundary.
- Preserved dependency failure paths and original causes, including the
first cancellation reason.
- Removed invalid-request logging that could expose Resource headers or
request bodies.
- Made editor cycle detection alias-safe by comparing underlying
Resource IDs.
- Memoized page settings values to prevent repeated async validation
renders.

## Verification

Latest local verification for `bbca6395e3`:

- Both queued-update regression cases failed before the fix and passed
afterward. Validation now runs synchronously immediately before
deletion, after the final await, in both cut paths.
- Passed: 255 copy/paste and command tests, Builder typecheck, lint,
package boundaries, formatting, and diff checks.
- Reviewed documentation: the existing copy/paste safety description
remains accurate. Fixture inputs and outputs are unaffected; no fixture
regeneration was needed. Agent evaluations were not run because separate
approval is required.
- CI for the new commit is pending.

Previous local verification for `ffbc75b152`:

- Six regression cases failed before the fix and passed afterward:
content edits, property edits, and project switches during a pending
cut, with both single and multiple selections.
- Passed: 253 copy/paste and command tests, Builder typecheck, lint,
package boundaries, source formatting, and diff checks.
- An unchanged content-block test file initially failed to import in the
browser. Its isolated rerun and the full 253-test rerun passed without
code changes.
- The guard conservatively treats any project-data change as a reason to
keep the clipboard copy without deleting content. It shows a retry
message. Copy/paste documentation now describes this behavior.
- Fixture inputs and outputs are unaffected; fixtures were not
regenerated. Agent evaluations were not run because separate approval is
required. CI for the new commit is pending.

Previous local verification for `3eb580697c`:

- Reproduced both regressions with failing tests before fixing them:
premature deletion during cut and false search exclusion appearing
checked.
- Passed: 203 copy/paste and page-settings tests, Builder typecheck,
lint, package boundaries, formatting, and diff checks.
- Cut coverage includes keyboard and programmatic entry points, single
and multiple selections, delayed successful writes, rejected writes, and
disabled copying.
- Reviewed documentation impact: these fixes restore existing behavior;
no documentation update is needed. Only Builder UI and clipboard files
changed; fixture inputs and outputs are unaffected, so fixtures were not
regenerated for this commit.
- CI status for this older commit was recorded as pending at handoff.
Agent evaluations were not run; they require separate approval.

Previous local verification for `858b348ad`, rebased onto `cf606ca4c`:

- Regression tests failed before each fix and passed afterward: repeated
submissions in both generated route templates, plus three
multi-root/branching cycle cases.
- Passed: 590 SDK tests, 1,129 CLI tests, 72 focused Builder tests,
SDK/CLI/Builder typechecks, lint, package boundaries, and fixture
link/sync/build.
- Initial concurrent runs hit timeouts. The complete CLI suite passed
with one worker; the focused Builder suites passed without file
parallelism.
- Documentation and generated fixture changes reviewed. Agent
evaluations were not run; they require separate approval.
- CI for `858b348ad` passed: Main (including all six E2E shards), Visual
Regression, Lint PR, and Check submodules.

Earlier verification (before this update):

TDD fail/pass evidence includes resolver creation, AST dependency
discovery, published graph reachability, dependency-gated request
generation, Builder dependency-first planning, Resource editor cycle
filtering, page-tree root scoping, off-page action isolation, transitive
Resource-only cycle discovery, abort/timeout precedence, server batch
limits, and the rebased SSG fixture consuming its lazy Resource.

- `pnpm checks` passed after rebasing onto `ce84ddcf12`; it covered
workspace tests, typechecks, lint, package boundaries, generated
API/docs validation, and fixture link/sync/build.
- Earlier focused checks passed: Builder typecheck, 12
page-settings/pages unit tests, lint, formatting, and `git diff
--check`.
- Local generated-resource E2E passed for HTTP, GraphQL, and
current-date resources (3 tests).
- The page-actions and Marketplace page-settings persistence E2Es both
pass locally.
- CI for `6b8b08a70` passed: Main workflow (including all six Builder
E2E shards), Visual Regression, Lint PR, and Check submodules.
- Agent evaluations were not run because they require separate explicit
approval.

## Current behavior and limitations

- A failed dependency blocks its dependents and reports the resource
path and cause.
- One published resolution call is the memoization boundary; Builder
maps dependency readiness onto its versioned request-cache lifecycle.
- Scoped collection-item and component-parameter resources remain in
#6031.
- Builder skips cyclic dependency paths without blocking independent
resources.

Oleg Isonen 804cd39bc2 fix: Stop slow diagnostics from blocking publishing and clarify publish status (#6416)
Closes #6406

## What changes

Publishing no longer waits for advisory content-database and MDX
diagnostics. Those checks run alongside the publish request, so a slow
diagnostic does not prevent publishing from starting.

Permissions, pending content saves, and blocking project checks still
run before publishing. The server continues to enforce publish
authorization and build integrity.

### Publish dialog

- Add a green **Validate** button beside the blue **Publish** button,
with equal widths.
- Show waiting states and disable the actions while their work is
running.
- Let users validate without publishing. Successful validation shows a
persistent “Validation passed. Ready to publish.” toast.
- Clear the button's **Validated** state when the popover closes.
Reopening still reflects an active publish job.
- Move **Add new domain**, **Export**, and **Publish settings** into the
header's ellipsis menu.
- Show yellow progress icons for publishing domains, green checkmarks
for completed publishes, red icons for failures, and neutral icons for
unpublished domains. Built-in and custom domains share the status
mapping.

### CLI and MCP

Add `check-publish-readiness` to check the saved project without
starting a publish. It checks permissions, rejects empty or unusable
domain selections, reuses the existing build-integrity checks, and
returns content diagnostics. Broken resource references no longer
produce a false `valid: true` result.

### Content checks

Run independent collection reads with bounded concurrency instead of
processing every collection sequentially. This reduces serial waiting,
but does not eliminate the underlying storage reads or content
processing.

## Checklist

- [x] Keep authorization and blocking project checks in place.
- [x] Run advisory content diagnostics alongside publishing.
- [x] Add standalone validation, waiting states, and popover-local
validation results.
- [x] Consolidate secondary actions in the publish menu.
- [x] Distinguish pending, completed, failed, and unpublished domain
states.
- [x] Add CLI/MCP readiness checks using existing integrity and
verified-domain logic.
- [x] Bound concurrent collection reads.
- [x] Add regression tests, including invalid domains, missing
resources, status transitions, and popover state.
- [x] Demonstrate the latest regression tests failing without the fixes
and passing with them.
- [x] Review documentation impact: update CLI operation guidance and
metadata, and document domain status colors in the publishing guide.
- [x] Run focused Builder, CLI, and asset-uploader tests, Builder
typechecking, lint, formatting, and the generated-API check.

## Verification and limits

The latest UI check passed all 49 publish tests. The preceding readiness
fix passed 98 focused Builder tests and 130 CLI tests; collection
coverage passed 112 tests. Typechecking, lint, formatting, and
generated-API checks passed. The latest fixes do not affect fixture
inputs or generated site output.

Storybook screenshots and agent evaluations were not run because
approval was not given. A live production publish was not performed
during the latest verification.

Publish can finish before advisory diagnostics do. Returned warnings
appear afterward and cannot stop a publish that has already started.
Standalone validation still waits for diagnostics, and actual publishing
still requires content synchronization, server checks, and
build/deployment work. This does not promise that every publishing
timeout is eliminated.

- Add one official `Alert` component with a content-editable `variant`
property for note, tip, important, warning, and caution.
- Register Alert in the component catalog with a generated title
descendant and Storybook story.
- Render GitHub-style alerts in Markdown Embed using the same DOM,
class, role, and variant contract.
- Materialize connected Content Block MDX alerts as actual Alert
instances and serialize content or variant edits back to `> [!TYPE]`.
- Document the component and both Markdown workflows.

## Implementation

Alert labels and variants live in Content Engine and are shared across
the component, Markdown renderer, and MDX adapters.

1. The Alert React component owns the wrapper, generated title, stable
classes, `role="note"`, and `data-variant`.
2. Markdown Embed transforms candidate micromark HTML before the
existing sanitizer and emits the same markup contract. It remains
sanitized HTML rather than a Builder instance tree.
3. Content Engine retains alert metadata on parsed Markdown blockquotes.
Project Build maps those nodes to Alert instances, reconciles their
authored children, and restores canonical GitHub syntax during MDX
serialization.
4. The component registry exports one Alert insertion template with a
styleable title descendant.

Unsupported, lowercase, misplaced, and malformed markers remain ordinary
blockquotes. There are no schema, migration, persisted-data, or
sanitizer-policy changes.

## Checklist

- [x] Add Alert as an official component with one Variant property.
- [x] Support all five GitHub alert types.
- [x] Share alert metadata and marker recognition.
- [x] Preserve nested Markdown and ordinary blockquote behavior.
- [x] Keep URL and HTML sanitization in the existing security boundary.
- [x] Add shared, title, and type-specific Markdown Embed descendants.
- [x] Materialize Content Block alerts as Alert instances.
- [x] Preserve alert content and variant changes through MDX
serialization.
- [x] Regenerate component props and Storybook artifacts from source.
- [x] Review documentation impact and update Alert, Markdown Embed,
Content Block, and navigation docs.
- [x] Verify fixture impact; no fixture inputs or generated fixture
outputs are changed.

## Verification

- [x] New tests demonstrated failure before implementation and pass
afterward.
- [x] `pnpm --filter @webstudio-is/content-engine test` — 417 passed.
- [x] `pnpm --filter @webstudio-is/project-build test` — 2,282 passed.
- [x] `pnpm --filter @webstudio-is/sdk-components-react test` — 144
passed, 1 skipped.
- [x] SDK component registry tests.
- [x] Relevant package typechecks, declaration builds, and production
builds.
- [x] Root lint, formatting, package-boundary, generated-doc, and diff
checks.
- [x] GitHub Actions main, E2E, lint, submodule, deployment, and
approved visual-regression checks.

## Known limitations

Alert identifiers must be uppercase and appear at the start of the
blockquote's first paragraph, matching the documented syntax. Markdown
Embed emits the component's markup contract but cannot create Builder
instances inside sanitized HTML.

Closes #6278

Oleg Isonen ea17eaa3c4 docs: explain the complete Content Engine workflow (#6403)
## What changed

- Add the complete Content Engine video tutorial to the main guide.
- Explain the launch benefits before the step-by-step setup: file-based
content, visual MDX editing, designed templates, collection entry forms,
and MCP automation.
- Document collection entry creation and editing in Content mode.
- Explain content collection folders in the Assets guide.
- Document that shared Slots cannot be used inside Content Block
Templates.
- Add missing links between Content Engine and Content Block
documentation.

## Release documentation audit

Reviewed the shipped MDX-backed Content Block, MDX template, structured
collection entry, collection authoring, query diagnostic, publication
warning, and asset-path changes. The detailed feature docs already cover
their implementation-specific behavior. This PR fills the remaining
discovery and workflow gaps across the main Content Engine, Assets,
Modes, and Content Block pages.

## Todo

- [x] Add the launch video to the Content Engine guide.
- [x] Update the main launch value proposition and supported scale.
- [x] Document collection workflows in Assets and Content mode.
- [x] Document the shared-Slot limitation for Content Block Templates.
- [x] Review documentation impact and navigation.
- [x] Verify generated documentation remains clean.
- [x] Verify changed relative links resolve.

## Verification

- Content Engine documentation tests: 2 passed
- Generated Content Engine and MCP documentation checks: passed
- Documentation TypeScript check: passed
- Relative link check: passed
- Git diff whitespace check: passed

The repository formatter excludes these GitBook Markdown files, so the
pre-commit formatting task had no eligible targets. No fixture inputs or
generated fixture outputs are affected.

Oleg Isonen f23007457d fix(content-engine): normalize asset path filters (#6389)
## Description

Fixes Assets path filters so authors can use visible folder and file
names while canonical stored paths remain URL-encoded.

- normalizes path filter operands segment by segment without double
encoding
- preserves already encoded filters and literal string matching behavior
- covers equality, inequality, membership, contains, starts-with, and
ends-with operators with spaces and URL-significant characters
- verifies local/Preview database execution and published runtime return
the same result
- documents visible path input in the generated Content Engine reference

Closes #6388

## Steps for reproduction

1. Create an Assets folder named `Tutorial posts`.
2. Add an MDX file inside it.
3. Create an Assets system resource with `path starts with "Tutorial
posts/"`.
4. Preview the query and expect the MDX file to match.
5. Change the value to `Tutorial%20posts/` and expect the same result
for backward compatibility.

## Regression proof

Before the implementation, the focused reproduction failed because the
matcher returned no items: expected `["alpha"]`, received `[]`. With the
fix, the expanded path-operator regression suite passes.

## Verification

- [x] Content Engine test suite: 47 files, 577 tests passed
- [x] Content Engine typecheck
- [x] CLI typecheck
- [x] Repository lint with warnings denied
- [x] Formatting check for every changed source/test file
- [x] Content Engine documentation test
- [x] Content Engine and MCP documentation generation is idempotent
- [x] Webstudio Features fixture generation is idempotent and typechecks
- [x] No agent evaluations were run

## Documentation impact

Updated the authoritative CLI Content Engine reference source and
regenerated the Builder Content Engine and MCP documentation. The new
guidance tells users to enter visible path names and notes that existing
encoded filters remain supported.

## Code Review

- [ ] hi @kof, I need you to do
  - conceptual review (architecture, feature-correctness)
  - detailed review (read every line)
  - test it on preview

## Before requesting a review

- [x] made a self-review
- [x] added inline comments where behavior is not obvious

## Before merging

- [ ] tested on preview environment (preview dev login: 0000)
- [ ] updated test cases document (not needed; automated regression and
authoritative user docs were updated)
- [x] added tests
- [x] no new environment variables

Oleg Isonen 5d34b77fac feat: Improve collection entry authoring (#6361)
Collection authors and editors get clearer field help, direct entry
navigation, and actionable validation instead of warnings that point at
the wrong place.

Closes #6360

## Implementation

- [x] Keep resettable help open after a click while the label remains
hovered
- [x] Stop repeating the property label inside resettable help
- [x] Store JSON Schema field descriptions and show them in entry forms
- [x] Add an optional dynamic collection entry page for explicit canvas
navigation
- [x] Rename entry file actions to **Edit file**
- [x] Add **Open on canvas** to entry menus and Entry settings
- [x] Put the entry filename in the Entry settings title
- [x] Make collection validation banners explain the problem and open
the first affected entry
- [x] Remove false output-only `UNOBSERVED_FIELD` warnings while keeping
filter and sort diagnostics
- [x] Encourage useful field descriptions in general MCP collection
guidance
- [x] Update Content Engine documentation
- [x] Confirm no database migration is required
- [x] Regenerate the affected asset-query runtime fixture
- [ ] Visually review the affected Storybook states in light and dark
themes
- [ ] Run the complete local agent evaluation suite
- [x] Run broader package and Builder checks
- [x] Complete final diff review

## Technical notes

- `entryPageId` lives in `collection.json` under `x-webstudio`; no
database schema changes are needed.
- Entry creation still leaves the current canvas unchanged. Canvas
navigation only happens after the user selects **Open on canvas**.
- An entry page must contain exactly one URL parameter. The entry
filename supplies that parameter, so the page can identify the selected
entry.
- Output projection fields are schemaless and may be produced after
reference resolution, so catalog absence is no longer reported there.
Filter and sort fields still report catalog diagnostics.
- The structured-query runtime change affects the generated
`webstudio-features` fixture, which is regenerated in this PR.

## Verification

- 561 Content Engine tests
- 2,413 Project Build tests
- 253 Design System tests
- 1,794 Builder tests
- 67 focused Builder regression tests after the final navigation change
- 11 ResettableLabel browser tests
- 128 focused MCP tests
- Builder, Content Engine, Design System, and Project Build typechecks
- Repository lint and package-boundary checks
- Generated documentation checks
- Full workspace fixture build with `pnpm -r fixtures:build`
- Formatting and diff checks
- New regression tests were demonstrated failing before their fixes and
passing afterward

## Documentation impact

- [x] Updated the Content Engine guide for field descriptions, dynamic
entry pages, actionable validation, **Edit file**, and **Open on
canvas**
- [x] Updated MCP guidance so collection fields include editor-facing
descriptions

Oleg Isonen e69a3d2f8e feat: Create structured MDX entries from collection folders (#6317)
## Paragraph editing follow-up — 42a16db02c (September 9)

Nested formatted paragraphs now retain their text, links, styling
identity, and existing labels during editing and saving. No database
migration.

- [x] Review all four changed text-editor files.
- [x] Preserve text before and after nested links inside emphasis,
strong text, and spans.
- [x] Preserve existing instance labels on save and keep inherited
formatting from overwriting a link's styling identifier.
- [x] Demonstrate regression failures without each fix, then pass all 41
focused text-editor and MDX synchronization tests.
- [x] Pass Builder typecheck, lint, formatting, and diff checks.
- [x] Verify the reported paragraph in Design and Content modes: edits
reach MDX and survive reload; original text restored. Verify matching
link color and underline inside and outside editing.
- [x] Review documentation and fixture impact: this restores existing
documented behavior; no fixture inputs, generated output, or
documentation changes are needed.
- [x] Commit and push the reviewed fixes.
- [ ] Confirm CI on this commit before merging.

Full E2E and agent evaluations were not rerun for this focused
follow-up. Earlier CI and suite results below apply to their recorded
commits, not this new head.

---

## Final verification — 50093ed2b7 (September 9)

Article edits now retain inline formatting and save newly inserted
custom components reliably. Saving a file no longer sends a second
project-sync write that could restore an older revision. No database
migration.

- [x] Fix iframe-blur saves, inherited template defaults, unused
resolved assets, and stale template tag metadata.
- [x] Remove duplicate server writes for already saved file revisions;
share the result with the canvas using the existing external-content
sync channel.
- [x] Demonstrate new regression tests fail without their fixes and pass
with them. Keep E2E file-write, content-order, and reload assertions;
remove the obsolete duplicate metadata-write wait.
- [x] Pass all 2,955 Builder tests, all 2,409 Project Build tests, and
all 8 focused MDX E2E checks.
- [x] Pass Builder and Project Build typechecks, lint, formatting, and
diff checks.
- [x] Run the complete fixture pipeline with no generated changes. The
later Builder-only save-acknowledgment changes affect no fixture inputs
or outputs.
- [x] Verify live article fields, hero replacement/save/reload/restore,
Accordion text edits, and YouTube URL edits. Verify UI edits reach MDX
and MDX edits persist after reload. Restore original article content.
- [x] Review documentation impact: these fixes restore the documented
Content Block editing behavior; no further documentation change is
needed.
- [x] Apply `visual-change-approved` after the user's explicit approval
of the 24 reviewed intended visual changes.
- [x] Commit and push the reviewed changes; worktree is clean.
- [x] Confirm CI and mergeability on this final commit: all 19 Main
workflow jobs passed, including all six E2E shards; PR lint and
submodule checks passed. Visual approval run 34383497017 passed. Its
predecessor reported the 24 intended differences; all 24 current images
were byte-identical to the reviewed report, with zero capture errors.
GitHub reports no merge conflict.

Agent evaluations were explicitly skipped for these final runtime fixes,
as requested. Earlier evaluation results below apply to their recorded
commits, not this final commit. This summary supersedes historical
pending-check notes below. The PR has not been merged.

---

## Final merge check — 9bc31ca679 (September 9)

- [x] Merge main without rewriting branch history. Preserve main's
image-picker fix and description-list validation.
- [x] Reset inherited HTML parent context at template boundaries. All
four new regressions fail without the fix and pass with it.
- [x] Fix shared navigation style composition and alignment; verify the
browser regression fails before and passes after. Review focused
screenshots.
- [x] Pass 2,408 Project Build tests, 251 design-system tests, and 3
image-picker tests; Builder, Project Build, and design-system
typechecks; lint, formatting, and diff checks.
- [x] Run the complete fixture pipeline with no generated changes.
- [x] Rerun all six agent evaluation scenarios on the merged code with
GPT-5.5. All functional checks pass; incompatible/missing token-baseline
comparison remains explicitly disabled.
- [x] Review documentation impact: this merge preserves documented
behavior; the image-editing guidance was already updated in f90e39cfcc.
- [x] Commit and push; worktree is clean and GitHub reports no merge
conflict.
- [x] Confirm Main CI on 9bc31ca679: all 19 jobs passed, including all
six E2E shards.
- [x] Review final visual artifact 10110845203 from run 34367911826: 24
added/changed stories, zero capture errors. Reviewed collection dialogs
and icons, light/dark login gradients, dashboard and project-settings
navigation, panel spacing, button variants, inset lists, and resettable
labels. Fourteen captures are byte-identical to the previously inspected
CI images. Updated navigation and collection-settings captures were
inspected; the formerly blank story renders normally. Pixel measurements
confirm the columns story retains its intended column positions (second
column x=261, third around x=388).
- [x] Apply visual approval after renewed explicit user approval.
Final-head CI is tracked above.

The live hero replacement and article/custom-component checks below are
now complete. The PR has not been merged.

---

## Merge-readiness follow-up — September 9

- [x] Remove contradictory image guidance and add an executable
writable-source/read-only-alt binding recipe. Regenerate CLI/MCP docs.
- [x] Verify the recipe regression fails with the old guidance and
passes with the new guidance. All 10 focused documentation tests, 2
content-reference tests, CLI/docs typechecks, lint, formatting, and
generated-documentation checks passed.
- [x] Rerun all six agent evaluation scenarios with GPT-5.5: all
functional checks passed. The incompatible/missing token-baseline gate
was explicitly disabled; existing baselines are unchanged.
- [x] Commit the documentation follow-up as f90e39cfcc.
- [x] Review existing CI screenshots and identify unintended shared-list
alignment changes. Implement a local shared-style composition/alignment
fix with a regression test demonstrated failing before and passing
after; all 251 design-system tests and its typecheck passed.
- [x] Visually verify and push the shared list fix in 9bc31ca679. The
focused run compared 28 stories; navigation is left aligned, column
layouts remain intact, and the previously blank collection-settings
story rendered normally. No product fix was inferred from that one blank
capture.
- [x] Review and approve the intended visual differences. See the
current final-head CI status above.
- [x] Verify these changes affect no fixture inputs or generated fixture
output. No database migration.

The previously pending live hero-swap and article/custom-component
checks are now complete. See the current verification summary above.

---

## Article editing follow-up — d307c8ba3d (September 9)

The target blog's hero source was incorrectly marked read-only. It now
uses the existing writable image picker. Reading time and the author URL
also use direct writable values. Time properties now have native
date/date-time controls. No database migration.

- [x] Fix the target's hero source, reading-time structure, and author
URL bindings while preserving the current content and link destination.
- [x] Verify Content-mode category, title, excerpt, date, reading-time,
shared image Description, author name/URL, MDX heading, and list-item
edits reach their source files. Check reloads and restore test values.
- [x] Add date-only, local timestamp, UTC timestamp, empty-value, and
legacy-value regression coverage; demonstrate failure without the date
control and passing results with it.
- [x] Fix the macOS Bash runner's empty-argument failure. Demonstrate
default invocation and argument-forwarding regressions fail without
their behavior and pass afterward.
- [x] Update authoritative Content Block/Time docs and generated CLI/MCP
guidance: inventory every article field, use direct writable bindings
and appropriate controls, check saved source and reload, and never infer
full editability from one heading.
- [x] Pass 291 date/text/Time/design-system tests (one existing skip), 2
runner tests, and 9 documentation tests; relevant typechecks, lint,
package boundaries, formatting, and diff checks.
- [x] Run the complete fixture pipeline: no generated fixture changes.
The later runner/docs-only edits do not affect fixture inputs or
outputs.
- [x] Run the full Builder E2E suite: 82 passed. This used an explicit
reporter; the default invocation correction was then covered by the
runner tests.
- [x] Run all six agent evaluation scenarios on gpt-5.5 after the final
image guidance correction. All functional checks passed. The older-model
token-baseline gate was disabled explicitly; accepted baselines were not
changed.
- [x] Review, commit, and push code and generated documentation.
- [x] With explicit approval, replace the live hero image through
Content mode, verify the MDX reference and reload, then restore and
verify the original image.
- [x] Complete the article-field checks listed above. Insert Accordion
and YouTube from templates; verify UI edits reach MDX and MDX edits
persist after reload. Restore the original article content.
- [x] Inspect CI for 7834d90a61: formatting, lint, typechecks, generated
docs, package/Builder tests, build checks, and five E2E shards passed.
The long MDX lifecycle exhausted its total 120-second budget at its
final assertion; the trace showed completed edits and reloads, not a
stalled save.
- [x] Give only that lifecycle a 180-second total budget; leave
individual save waits and assertions unchanged. Both local repeats
passed (plus setup). Push d307c8ba3d; this test-timeout-only follow-up
affects no fixture inputs or generated output.
- [x] Verify Main CI for d307c8ba3d: all 19 jobs passed, including all
six E2E shards. Visual approval remains separate.
- [x] Finish visual review and approval after correcting navigation
alignment and verifying the collection-settings story renders. The user
approved the reviewed 24 intended differences.
- [x] Recheck target publication preparation: seven documents included,
zero omitted, zero missing-template omissions. No deployment.
- Deferred: manual Storybook/screenshots; not authorized for this pass.

These results supersede the earlier pending image-product decisions and
live-check notes. Evaluation status for the latest fixes is recorded
above.

## Blog authoring fixes — 6359f979a3 (September 9)

This review fixes failed UI-to-MDX saves, missing source Undo/Redo,
editor recovery and focus, and publication preparation for the migrated
blog. No database migration.

- [x] Stop treating template-record ordering as a style edit; still
reject actual style changes that cannot be saved in MDX.
- [x] Share save-preparation errors with property controls across the
canvas frame.
- [x] Keep malformed MDX as an unsaved draft, with repair and discard
paths; focus the source editor when opened from the Navigator.
- [x] Enable supported Content-mode Move actions using the existing
central permission rules.
- [x] Keep source Undo/Redo separate from transient rendering history.
Serialize rapid commands, wait for pending canvas edits, reject
stale-source conflicts, and retain the last 20 edits per project
session.
- [x] Fix publication candidate discovery for projected documents and
unrelated author references; keep rejecting unsupported references used
as the actual MDX source.
- [x] Demonstrate regression tests failing without their fixes and
passing afterward.
- [x] Run the complete Builder (2,938), Content Engine (559), and
Project Build (2,395) suites: 5,892 tests passed.
- [x] Pass relevant package typechecks, root lint, formatting, package
boundaries, and diff checks.
- [x] Run the full fixture pipeline; no generated fixture changes.
- [x] Review documentation impact and document draft recovery and source
Undo/Redo.
- [x] Verify live heading edits, author-file edits, malformed-draft
recovery, and immediate delete/Undo/Redo; restore test content and
confirm persisted source.
- [x] Verify target publication preparation: seven documents included,
zero omitted, no missing-template omissions. This did not deploy the
site.
- [x] Review, commit, and push.

### Remaining verification and decisions

- [x] Correct the target's read-only Image source binding. The existing
Content-mode picker replaces the article reference; shared Description
edits use Asset settings. No new image-editing API or data model is
needed. See the latest verification limits above.
- [x] Repeat the full E2E and agent evaluation suites after these
changes: 82 E2E tests and all six evaluation scenarios passed.
- [x] Repeat the live Accordion/YouTube insertion and editing flow after
the save fixes, including UI-to-MDX saves and MDX edits surviving
reload.
- Historical note: this round did not run CI or Storybook checks; later
results are recorded above.

Unknown JSX already has source-range lint diagnostics; it remains an
editable missing-template placeholder, not an unconditionally blocked
save. The target author's binding was also repaired through the UI so
Content mode can edit its referenced author file. Shared resolved URLs
remain read-only text; the image picker changes the article reference,
and Asset settings edits the shared Description.

This section supersedes earlier claims of complete verification for the
latest code; historical results below remain records of earlier runs.

---

## Sync and import verification — a2a567551c (September 9)

Ordinary `link` → `sync` → `import` now exports the current saved
Builder project with its current assets. It no longer mixes an older
published build with current files. Import uploads assets before
assigning their source folders, then restores those assignments when
importing the bundle.

- [x] Fix foldered asset imports without a database migration.
- [x] Preserve file formats, folder assignments, build metadata, and
stable repeat-sync output.
- [x] Keep explicit `--buildId` export behavior unchanged; default sync
does not require publishing.
- [x] Review implementation and demonstrate regression tests failing
before the fixes and passing afterward.
- [x] Update protocol test servers for the current Builder data
endpoint.
- [x] Review documentation impact and update CLI documentation and
README.
- [x] Run all 1,121 CLI tests and 43 HTTP-client tests, both package
typechecks, root lint, package boundaries, formatting, and diff checks.
- [x] Run the full fixture pipeline and include expected current-build
fixture changes.
- [x] Verify the real source through the local CLI: repeated sync gives
identical output; import into the supplied target succeeds. Blog listing
and article rendering were also checked during the import investigation.
- [x] Commit and push the fix.
- Deferred at user request: agent evaluations for this round. Later CI
results are recorded above.

Sync still downloads the project and missing asset files and builds the
content index locally. This is not a transfer-free operation. Default
sync exports editable-build metadata rather than published deployment
metadata; use the explicit build option when selecting a particular
build.

---

## Final review and verification — ab3a6b7c55 (September 9)

Existing entries now use the same field controls as New entry. The
author-name permission fix, field-level validation, publishing warnings,
and final cache fixes are included. No database migration.

### Completed

- [x] Review all 38 local files, including entry autosave, revision
conflicts, permissions, shared fields, collection discovery, and
publishing diagnostics.
- [x] Allow existing-folder setup without rewriting entries or rejecting
unconfigured frontmatter.
- [x] Add Entry settings with autosave, repairable invalid fields,
immutable filename slugs, and preserved MDX body/unknown properties.
- [x] Warn before publication when missing or ambiguous custom templates
omit content, including discovered dynamic sources.
- [x] Allow authorized frontmatter writes to referenced Markdown author
files and preserve error messages across the canvas-frame boundary.
- [x] Reject impossible integer limits, slugless generated-filename
patterns, and slug maximum length zero. Existing raw configurations
remain readable for repairs.
- [x] Share collection discovery across Assets, file editors, and
property controls. Builder first synchronizes project asset metadata
into the browser. The browser then groups that metadata once per update
and shares configuration/template reads, instead of repeating them for
each control. This does not remove initial synchronization or
entry-frontmatter reads. Preserve project/access isolation, refresh
retries, stale-response protection, and duplicate-filename invalidation.
- [x] Demonstrate new regressions fail before fixes and pass afterward.
- [x] Correct the folder-drag E2E's obsolete root-folder assumption and
verify remembered-folder persistence.
- [x] Review and update authoritative Content Engine and Content Block
documentation.
- [x] Merge current main and regenerate the conflicting CLI
documentation from its source.
- [x] Fix generated previews with shared development dependencies:
invoke React Router binaries through Node, isolate each preview's Vite
cache, and forward script options correctly through npm and pnpm.
- [x] Fix a false MDX conflict when a new edit arrives immediately after
the previous save is acknowledged. Advance the local revision before
asynchronous parsing and ignore stale refresh results.
- [x] Run the full fixture link/sync/build pipeline. Generated changes
contain only the expected React Router scripts and Vite cache location.
No database migration.
- [x] Review the final diff and scan added lines for credential
patterns.

### Verification results

- Builder: **2,934 tests passed**. CLI: **1,120 tests passed**.
- Content Engine: **559 passed**; Asset Uploader: **291 passed**;
Project Build: **2,394 passed**; Design system: **250 passed**.
- The clean full workspace run passed all 35 non-CLI packages. Its two
CLI failures exposed pnpm argument forwarding; the complete CLI rerun
passed after that fix. Earlier load-related test timeouts did not recur
in the clean run.
- All workspace typechecks passed. Builder and CLI typechecks and
repository lint were repeated after their final changes. Package
boundaries, generated API checks, and the complete
generated-documentation gate passed. Documentation was regenerated from
source; the post-commit clean-file check passed.
- Full Builder E2E: **82 passed** from a fresh build, including
generated previews, collection creation/reload, MDX editing, stale
revisions, and permission checks. The isolated disposable test database
was cleaned up afterward; development data was untouched.
- Full agent evaluations: **all six scenarios passed on gpt-5.5**,
including every functional check for Markdown blogs, reference
discovery, MDX article editing, authentication, fonts, and design input.
The account cannot use the old **gpt-5.4-mini** baseline model. Five
baseline comparisons are incompatible and the MDX scenario has no
accepted baseline; token-baseline gating was disabled explicitly.
Accepted baselines are unchanged.
- New preview and MDX regressions were demonstrated failing before their
fixes and passing afterward.
- Working-tree/diff checks passed. Main was merged without rewriting
branch history. CI was not checked, as requested.

### Final delivery checklist

- [x] Finish the full Builder E2E rerun.
- [x] Finish the full agent evaluation rerun with the authorized
accessible model.
- [x] Commit, verify the clean generated-documentation gate, and push.
GitHub reports the branch mergeable with current main.

No known code or functional-test blocker remains from this review. CI
was not checked at the user's request. Manual Storybook/screen-reader
checks remain deferred; the automated E2E and agent visual checks above
passed.

The historical review sections below retain their original run results.
This section supersedes earlier claims about strict entry validation,
entry editing, browsing reads, and evaluation authorization.

## Outcome

Content editors can create structured MDX entries from a collection
folder without writing frontmatter. Designers configure flat fields,
limits, optional slug behavior, and the Markdown template in the
Builder.

## High-level goals

- [x] Keep folders ordinary in the database and derive collection
behavior from a direct **collection.json**.
- [x] Add **Use as content collection** to folder creation.
- [x] Give designers a visual configurator for the JSON Schema and MDX
template.
- [x] Show a collection badge and a generic **New entry** action.
- [x] Generate independent MDX entries from the configured schema and
template.
- [x] Keep the current page unchanged after creating an entry; no
automatic preview navigation.
- [x] Select direct MDX entries with URLPattern filename rules; keep
ignored files as ordinary supporting assets.
- [x] Keep reserved collection files out of collection query results and
generated content indexes.
- [x] Preserve broken collections as visible, repairable collection
folders.
- [x] Restore normal folder behavior when **collection.json** is
removed.

## Implementation todos

- [x] Add the Content Engine collection contract, default
schema/template, slug normalization, validation, serialization, and
entry generation.

while excluding it from content query and generated-index results.
- [x] Document the feature in the authoritative Content Engine guide.

## Deep review checklist

A checked item means the area was inspected and evidence was recorded.
It does not mean the behavior passed. Unresolved defects and product
decisions remain listed in **Review findings**.

### 1. Product contract

- [x] Decide whether the collection checkbox creates defaults
immediately or opens the configurator first.
- [x] Decide whether existing folders can be converted through the UI.
- [x] Define collection activation when **collection.json** exists but
is invalid.
- [x] Define an entry: every valid direct MDX child or only files
created through **New entry**.
- [x] Confirm collection membership is direct-child only and nested
folders can define their own collections.
- [x] Define designer, content editor, viewer, service, CLI/MCP,
old-client, and direct-API authority.
- [x] Decide whether content mode is simplified UI or a server
authorization boundary.
- [x] Decide whether slugs are permanently immutable.
- [x] Decide whether schema changes may invalidate existing entries or
must migrate them.
- [x] Decide whether invalid unused collections block unrelated queries
or whole-project publication.
- [x] Decide what happens to the preserved template after collection
removal.
- [x] Define the promised JSON Schema dialect and supported subset.
- [x] Decide whether temporary invalid collection states are admitted
for repair.
- [x] Define duplicate-request semantics: no duplicates, exactly one
success, and retry behavior.
- [x] Decide whether entries require valid frontmatter only or valid
complete MDX.

internals.

### 28. Verification strategy

- [x] Unit-test schema, slug, merge, serialization, and validators.
- [x] Demonstrate each new regression test fails without its fix.
- [x] Run affected unit suites, typechecks, lint, docs checks, E2E,
fixture-impact review, and final diff review.
- [x] Review authoritative documentation impact.

## Persistence and recovery

No database migration is needed. Folders remain ordinary database rows;
their direct **collection.json** activates collection behavior. This PR
adds no table, column, index, RPC, folder type, or backfill.

- Setup writes the template first and **collection.json** last.
Interrupted setup leaves an ordinary folder and can be retried.
- Existing immutable File revisions, conditional Asset updates, and
upload reservations provide conflict detection and retry-safe entry
creation.
- Settings saves validate the intended template and schema together,
then write only the files that changed. Existing entry field errors stay
repairable and do not block unrelated saves, queries, or publication.
New entry creation remains strict.
- Invalid or interrupted collections remain visible and repairable.
Configuration/template structure errors remain distinct from entry-field
errors; entry-field errors do not invalidate the entire collection.
- Public/service publication excludes configuration and template files.
Authenticated CLI exports retain them for lossless import.

## Review findings

The implementation review is complete. Confirmed defects were fixed and
the following tradeoffs remain explicit.

### Fixed

- Enforced collection structure and permissions across REST, runtime
patches, import, query, and publication, while keeping existing
entry-field errors non-blocking for queries and publication.
- Preserved Undo/Redo, including restoring shared File revisions in
cloned projects.
- Rejected forged shared-file metadata while preserving metadata edits
on legacy files with null uploader provenance.
- Added retry and recovery behavior for setup, settings saves, lost
responses, and transient reads.
- Moved collection setup into one retry-safe server operation and kept
the local Builder update as one Undoable transaction.
- Centralized collection inspection and limited schemas to the flat
fields the configurator can represent. Opening a collection still reads
its entries in the background to report field errors.
- Guarded stale dialogs and deferred saves against permission changes,
protected files, project switches, and replaced revisions.
- Kept Asset settings open while choosing nested folders; the existing
browser regression fails before the fix and passes afterward.
- Preserved required Boolean false values, field-level errors,
dirty-close prompts, and inline Markdown editing.
- Separated authenticated portable exports from public runtime assets.
- Updated the authoritative Content Engine guide.

### Known tradeoffs

- A failure after template content saves but before configuration saves
can temporarily leave an invalid collection. Retrying the settings save
completes it; otherwise the visible files allow repair. The
template/config rename endpoint remains retry-safe and rolls back a
rename when its config write fails.
- Cloned-project Undo can retain an unused prior File revision. Separate
read-then-delete cleanup could race with another restore, so this path
retains the revision.
- Build/asset persistence and import already use multiple calls. This PR
validates before writes and provides retry/conflict handling; it does
not provide a transaction spanning every resource or a global collection
lock.
- Opening a collection loads its configuration and template through
shared Builder discovery, then checks entry frontmatter in the
background for field errors. Unchanged configuration/template content is
reused across controls and entry edits. Frontmatter checks still require
entry reads; ordinary folder browsing does not discover every
collection’s file content.

## Latest unstaged-change review — 2026-09-07

- [x] Review collection settings, validation, autosave/error recovery,
entry creation, reserved-file actions, and conversion flows.
- [x] Review shared labels, list keyboard handling, dialog focus/Escape,
buttons, and panel spacing migrations.
- [x] Fix Enter/Space list activation lost when arrow navigation
replaced the existing press handler.
- [x] Recognize historical generated ASCII/Unicode slug patterns, use
the bundled Unicode slug schema, and save a locally resolved $ref
without changing existing filenames.
- [x] Prevent duplicate slugless entries after a lost response: New
entry sends a stable UUID per attempt, reused by the repository's
existing filename/content retry checks. No database migration. Callers
omitting the optional requestId retain the previous behavior.
- [x] Preserve Content Block template validation independently of page
HTML placement, without accepting invalid rendered nesting.
- [x] Demonstrate the new review regressions fail without their fixes
and pass afterward.
- [x] Review authoritative documentation and update legacy slug
behavior.
- [x] Run fixtures and inspect generated changes: none.
- Deferred manual verification: Storybook screenshots were not
authorized for this pass.
- Historical evaluation status: not run in this pass; superseded by the
final verification section above.

## Verification

Local checks for commit **2b8195692e**:

migration, or generated database type changes. The lockfile includes the
collection validator and filename matcher dependencies.
- CI for this commit is pending. Builder E2E, manual
screen-reader/mobile checks, Storybook screenshots, and agent
evaluations were not run in this pass.

## MDX editing review — commit c3702a7238

- [x] Review all 36 local changed files: MDX parsing/materialization,
template enforcement, mutation commits, persistence, Assets refresh,
Navigator, source binding, editor diagnostics, dialogs, and query menus.
- [x] Validate new custom components at the shared Builder mutation
commit before applying tree changes. Cover move, reparent, paste, nested
paste, duplicate, and batched operations; preserve unchanged authored
content.
- [x] Match template names and component structure, including renamed
templates, instead of accepting any component type found in Templates.
- [x] Remove the registered-component fallback from MDX materialization
and completion; report untemplated JSX in the editor.
- [x] Preserve unresolved JSX until its placeholder is deleted, then
persist its removal without clearing the Assets resource during refresh.
- [x] Keep custom designer content outside the MDX body; omit the extra
body for fresh unconnected Content Blocks.
- [x] Resolve Navigator's MDX-file action from the active content root
for dynamic sources.

- Fixture link/sync/build passed without generated changes. No database
migration.
- CI for this commit has not yet been verified.

The new mutation-commit check covers Builder operations affecting loaded
external content roots. It is not a claim that every remote API mutation
is now guarded by this client-side check.

Closes #6316


## Local-change review — 2026-09-08

- [x] Review all 47 changed files and trace collection setup, filename
filters, public metadata/upload APIs, sync patches, Content-mode write
targets, local folder persistence, and MCP downloads.
- [x] Fix ignored MDX files being renamed into entries through the
metadata API. Selected filenames require New entry.

invalid entries. Configuration/template checks still run. The later
entry-repair work also removed entry-field validation as a blocker for
unrelated writes and publication.

project-build (2,394), MCP command (61), and collection/Content-mode
browser tests (279), plus expression tests and documentation checks.
- [x] Pass seven affected package typechecks, repository lint,
formatting, package boundaries, and fixture link/sync/build. No
generated fixture changes or database migration.
- Historical evaluation status: deferred in this pass; the user
subsequently authorized the full suite. See the final verification
section above.
- Historical verification limits: no Builder E2E or manual
visual/accessibility checks in this pass. See the final verification
section for the current E2E result; manual checks remain deferred.

Oleg Isonen 722b3af113 feat: Copy links to instances from the context menu (#6342)
Right-click an instance in the Navigator and choose **Copy link to
instance** to share its full Builder URL. Opening it restores the page
and the same instance occurrence, including descendants of shared Slots.
The shared menu also exposes the action on the canvas.

Copying and opening a link use the same existing
`getDeepLinkedInstanceSelection` function, moved unchanged from
`use-switch-page.ts` into `shared/instance-utils/link.ts`, alongside URL
creation and the existing instance URL parser. It validates the instance
path and page access. The context menu and pre-publish “Show element”
links both call `getInstanceLink(instanceSelector)`. It lives in
`shared/instance-utils/link.ts` and owns validation and the complete URL
setup: project, page, full selector, origin, share token, editor mode,
and safe mode, using the existing `builderUrl`. There is no separate
link-permission implementation.

The link keeps the current share access and editor mode, clears
unrelated scroll anchors, and shows clipboard success or failure. Body
is supported; Global Root and multiple selections are unavailable.

Instance-only navigation now preserves loaded Builder data: the route
comparison recognizes the `instance` parameter as well as the older
`instanceId`. A functional regression test confirms that changing the
target does not change the data URL comparison, while changing share
access does.

MCP guidance explains how to extract the target ID from the link for
`inspect-instance`, verify the project and shared Slot context, and
avoid guessing when an instance no longer exists. This does not add a
URL-taking MCP endpoint.

1. [x] Add the menu action and reuse complete instance-link construction
with pre-publish links.
2. [x] Share existing instance-link validation between copying and
opening links.
3. [x] Update the Navigator and MCP guidance; regenerate CLI
documentation.
4. [x] Extend the existing functional test to round-trip a shared Slot
URL, including share access and editor mode. Verify it fails without the
instance parameter and passes after restoration.
5. [x] Remove the React/clipboard test harness and duplicate
permission-test matrix. Confirm no fixture inputs or outputs are
affected.

Validation: 28 focused Builder tests, Builder typecheck, repository
lint, and `git diff --check` pass on this revision. The earlier CLI
documentation checks passed and their inputs are unchanged. An earlier
GPT-5.4 mini subagent at low reasoning passed a focused native MCP test
against commit 072a8dc534: given only a link and text-edit request, it
changed the correct heading among three identical-looking headings,
leaving all other fixture records unchanged. It used four MCP calls with
broad instance/text reads. That agent test used an isolated local
fixture; it was not a production or shared-Slot agent test. Screenshots
and the full agent evaluation suite were not run.

Closes #4610

Oleg Isonen 05706b5425 feat: Make Content Block templates the MDX authoring interface (#6307)
Closes #6306

## Outcome

Content Block templates are now the public component model for MDX
authoring.

- Standard Markdown resolves through matching Content Block templates.
- PascalCase JSX resolves to a named template first, then to a
registered component.
- Adding or changing a template immediately affects matching MDX,
including content authored before that template existed.
- Every supported standard MDX element is present in new Content Blocks
by default.
- Template `name` is a stable PascalCase JSX identifier. `label` remains
optional display text only.
- Lowercase JSX represents native HTML and SVG without exposing
`ws.element` in authored syntax.
- Unknown, ambiguous, and unsafe JSX stays in source, produces a
source-ranged Builder diagnostic, and is omitted from published output.
- Frontmatter images preserve exact `$ref` values and use the Asset
description for `alt` text.
- Keyboard and mouse insertion from the slash menu remove the trigger
slash and preserve the selected template.

## Public MDX contract

- Markdown is canonical for standard prose.
- Lowercase JSX creates native elements:
`<section><p>Text</p></section>`.
- PascalCase JSX uses templates and registered components:
`<PromotionCard />`, `<Heading tag="h1">Title</Heading>`, and `<YouTube
src="https://youtu.be/KI5JHpzBK1s" />`.
- Component-name collisions use stable qualified identifiers such as
`Checkbox` and `RadixCheckbox`.
- A self-closing template keeps its designed default subtree. An
explicitly paired empty template clears it.
- Static quoted values and bare booleans are supported.
- Imports, exports, expressions, spreads, functions, executable
JavaScript, unsafe attributes, `<$.*>`, and authored `<ws.element>` are
rejected.
- `ws` remains only for compiler primitives with no React component.

## Implementation

- [x] Add stable, unique template names and keep them separate from
labels.
- [x] Parse and validate Markdown and JSX through their ASTs with
precise source ranges.
- [x] Share component identity between template JSX, Content MDX,
Builder materialization, reload, copy, and publication.
- [x] Resolve templates live after add, edit, rename, reorder, removal,
undo/redo, collaboration updates, and reload.
- [x] Preserve authored props, children, Asset references, template
defaults, and the exact slash-menu template choice.
- [x] Make one typed MDX semantic inventory drive default templates and
slash-menu eligibility.
- [x] Move component-dependent template assembly into the component
registry.
- [x] Replace production `$`, `animation`, and `radix` JSX namespaces
with direct component imports.
- [x] Keep only explicit compiler primitives in `ws` template JSX.
- [x] Migrate repository templates, fixtures, stories, examples, MCP
guidance, CLI guidance, and generated outputs.
- [x] Add Builder unit and Playwright coverage for authoring,
diagnostics, insertion, synchronization, reload, and publication.
- [x] Review and update the authoritative Content Block and generated
MCP documentation.

## Compatibility

- Persisted project data continues to use namespaced component IDs and
`ws:element` for generic HTML elements. No project-data migration is
required.
- Legacy `<ws.element ws:tag="…">`, `<ws.element ws:name="…">`, `<$.*>`,
`<animation.*>`, and `<radix.*>` input remains readable during the
compatibility window.
- Current serializers and repository-owned sources emit only canonical
Markdown, lowercase intrinsic JSX, or PascalCase identifiers.
- Untouched user MDX is not rewritten automatically. Legacy syntax is
canonicalized when its owning source is edited.
- Deferred follow-up: remove legacy namespace readers and proxy support
only after the canonical writer is deployed and existing projects are
backfilled. This is intentionally outside this PR.

## Verification

- [x] CI package tests, typechecks, lint, package boundaries, generated
assets, migrations, and size checks pass.
- [x] All six Builder E2E shards pass.
- [x] Fixture checks pass on Ubuntu and Windows.
- [x] Targeted local Content Engine, Template, SDK, registry, Project
Build, migration, Builder, component, CLI, and Playwright tests pass.
- [x] Runtime contracts, CLI docs, and MCP docs were regenerated from
their owning sources.
- [x] Local fixture generation completed without an unexpected fixture
diff.
- [x] Documentation impact reviewed and included in this PR.
- [x] Review and approve the intentional List visual snapshot change.
- [x] Run the complete agent evaluation suite after explicit approval.
- [x] Run the network fixture link/sync pipeline against the matching PR
deployment after explicit permission.

## Known visual change

The generated List story now targets its actual default `ul` element
instead of `ol`, so the default list styling appears in the visual
snapshot. The visual change was reviewed and the approved visual check
passes.

Oleg Isonen 2e39477303 feat: Expose Force Mount for Collapsible Content (#6338)
## Problem

Closed Collapsible Content is removed from the HTML, and the Builder
does not expose Radix’s Force Mount option.

## Solution

- Expose **Force Mount** as a boolean on Collapsible Content.
- Enable it for newly inserted Collapsible templates.
- Keep closed force-mounted content visually collapsed with template
styles.
- Preserve the existing Radix default for existing instances that do not
set the prop.
- Add regression coverage for the template default and generated Builder
metadata.

## Checklist

- [x] Expose the Force Mount control
- [x] Keep new Collapsible content mounted while closed
- [x] Preserve existing-instance behavior
- [x] Regenerate Collapsible prop metadata from source
- [x] Add regression coverage
- [x] Review documentation impact and update the Collapsible guide
- [x] Verify fixture inputs and outputs are not affected

## Verification

- [x] `pnpm --filter @webstudio-is/sdk-components-react-radix test` — 20
tests passed
- [x] `pnpm --filter @webstudio-is/sdk-components-react-radix typecheck`
- [x] `pnpm --filter @webstudio-is/sdk-components-react-radix build`
- [x] Targeted Oxlint and formatting checks
- [x] `git diff --check`

## Known limitations

Storybook visual verification was not run because it requires separate
approval.

Oleg Isonen 55920c57c4 fix: Show all Markdown and Assets query diagnostics (#6308)
Ref #6305

## Outcome

Show actionable Markdown, MDX, and Assets query problems in the editor,
query Diagnostics, API, and MCP.

The current implementation substantially improves source diagnostics,
query error aggregation, query scoping, exact paths, MCP feedback, and
loading states. The exhaustive audit below also records what is not
complete yet.

## Completion rule

An error state is complete only when all applicable checks pass:

- [x] The editor uses the production validator and shows every issue for
the open file.
- [x] Query execution uses the same validation and returns every issue
for every file that matches the query, not only the returned page.
- [ ] MCP can reproduce the state through a real tool call and returns
the same code, severity, message, file, and location.
- [x] Diagnostics shows fatal errors and nonfatal warnings in the
correct place.
- [x] Exact file is always present; line and column are present whenever
the parser can determine them.
- [x] Multiple issues in the same file, multiple files, and multiple
validation phases are returned together.
- [ ] A regression test proves failure without the behavior and success
with it.

## Cross-surface contract

### Required validator parity

- [x] Editor, query execution, and MCP file operations invoke the same
exported production file-validation pipeline for byte decoding,
source/frontmatter, Markdown/MDX, Content Block semantics, and
references. Copied schemas, adapter-only checks, or reimplementations do
not count as parity.
- [x] Query builder, query execution, `validate-asset-query`, and
`preview-asset-query` invoke the same exported structural and
catalog-aware semantic query validator with the same project snapshot
and context.
- [x] Every surface preserves the same complete, deterministically
ordered diagnostic array: severity, code, message, phase/scope, asset
ID, file path, line/column/range, query path, and
fatal-versus-warning/result behavior. UI, API, and MCP serializers must
not drop or remap fields.
- [ ] A table-driven contract suite calls the real editor, query, API,
and MCP entry points—including MCP upload, update, download, validate,
and preview—and compares full normalized arrays for multiple errors,
multiple warnings, multiple files, and pre-pagination matches.

- [x] Markdown and MDX source syntax/frontmatter use
validateTextAssetSource in editor, query compilation, and MCP file
tools.
- [x] Query request execution and MCP local parsing use
assetQueryRequest.
- [x] Fatal query setup errors retain all detected semantic errors and
accompanying warnings.
- [x] Nonfatal query warnings retain a stable code and exact query path.
- [x] Source diagnostics retain severity, phase, code, asset ID, path,
and available source position.
- [x] Query Diagnostics excludes diagnostics produced only by unrelated
published queries.
- [x] Query, Preview, and Diagnostics tabs show loading states.
- [x] Authenticated diagnostics can show a sanitized internal message;
public/pre-auth errors remain redacted.
- [x] Share byte-level UTF-8 validation instead of decoding separately
in query and MCP.
- [x] Make the query editor and MCP call one literal shared
query-validation function before execution.
- [x] Share cross-file reference validation across editor, query, and
MCP file operations.
- [x] Share contextual Content Block/template validation across all
applicable surfaces.
- [x] Preserve an invalid stored query in the editor and explain it
instead of replacing it with defaults.
- [x] Define and enforce whether “matches the query” includes every
pre-pagination match; current source validation follows
returned/paginated IDs.
- [x] Continue through source, reference, and runtime phases where safe
so one phase does not hide later issues.
- [x] Map every user-triggerable graph/storage/runtime failure to a
structured public error instead of INTERNAL_ERROR.
- [ ] Label candidate-file warnings separately from returned-file
diagnostics.

## File transport and encoding

- [x] Empty Markdown and MDX are accepted.
- [x] UTF-8 BOM and CRLF are accepted.
- [x] Whole Markdown/MDX file over 1 MiB is detected.
- [x] Missing or unavailable selected content is reported.
- [x] Invalid UTF-8 frontmatter returns the same structured diagnostic
in query and MCP.
- [x] Invalid UTF-8 body returns the same structured diagnostic in query
and MCP.
- [x] MCP download must use fatal UTF-8 decoding rather than replacement
characters.
- [x] Validate bytes before committing an upload, or return the
committed Asset ID and explicit cleanup state when post-commit feedback
fails.
- [x] Reject filename/format mismatches instead of allowing either hint
to bypass Markdown/MDX validation.
- [x] Storage status, missing body, invalid metadata, revision mismatch,
format mismatch, short read, and excess read each return structured file
context.
- [x] Content changing during validation has a clear retryable conflict
diagnostic.

## Frontmatter

- [x] No frontmatter.
- [x] Empty frontmatter.
- [x] Opening delimiter without a closing delimiter.
- [x] Frontmatter over 64 KiB.
- [x] Invalid YAML grammar.
- [x] Multiple YAML parser errors.
- [x] Duplicate keys.
- [x] YAML aliases.
- [x] Unsupported YAML tags.
- [x] Scalar or array root instead of an object.
- [x] Non-JSON values, NaN, Infinity, and unsafe integers.
- [x] Nesting deeper than 8.
- [x] More than 256 fields/array entries.
- [x] One string over 16 KiB.
- [x] Normalized indexed properties over 64 KiB.
- [x] Frontmatter warnings remain nonfatal and visible.
- [x] Collect all post-parse normalization/limit errors; this phase
currently stops at the first.
- [ ] Prove every state above through real MCP upload, update, download,
query, and Diagnostics paths.

## Markdown body

- [x] Treat ordinary CommonMark/GFM as permissive; malformed-looking
Markdown and raw HTML are not automatically syntax errors.
- [x] Preserve and validate the body when frontmatter is invalid.
- [x] Detect the 1 MiB body/file limit.
- [x] Handle body extraction and bounded excerpts.
- [x] Return a shared structured invalid-UTF-8 body error from every
byte-reading surface.
- [ ] Distinguish author errors from internal
excerpt-limit/configuration errors.
- [ ] Prove body-size and decoding states through real MCP and
Diagnostics.

## MDX grammar and safety

- [x] Malformed MDX/JSX grammar.
- [x] Imports.
- [x] Exports.
- [x] Executable flow expressions.
- [x] Executable text expressions.
- [x] JSX expression attributes.
- [x] JSX spread attributes.
- [x] Arbitrary components.
- [x] HTML-looking JSX outside ws.element.
- [x] Unsupported/raw MDX node types.
- [x] Duplicate attributes and normalized alias collisions.
- [x] Event-handler attributes.
- [x] srcdoc, srcset, and dangerouslySetInnerHTML.
- [x] Unsafe URL protocols in link/source/action-like props.
- [x] Forbidden tags: base, link, meta, noscript, script, style,
template, title.
- [x] Conflicting, empty, or non-static ws:name and ws:tag.
- [x] More than 20,000 nodes.
- [x] Nesting deeper than 100.
- [x] More than 4,000 props.
- [x] Multiple recoverable unsafe-mdx warnings are collected.
- [ ] Collect multiple fatal grammar/structural errors when parser
recovery can do so; unrecoverable parsing currently stops at the first
fatal error.
- [x] Preserve sibling expression warnings when unsupported JSX is also
present; {first()}, <Card />, {second()} currently reports only the Card
warning.
- [ ] Prove every state above through real MCP and Diagnostics, not only
validator unit tests.

## Content Block semantics

- [x] Unresolved template warning exists.
- [x] Unknown template prop warning exists.
- [x] Incompatible template prop warning exists.
- [x] Design-only template prop warning exists.
- [x] Stale template prop warning exists.
- [x] Invalid materialized HTML content model error exists.
- [x] Run these checks for an MDX file even when no active editor
Content Block root has materialized it.
- [x] Run applicable semantic checks in query Diagnostics.
- [x] Run applicable semantic checks for MCP upload as well as
contextual update/download.
- [x] Return all Content Block frontmatter diagnostics; one path still
throws only diagnostics[0].

- [x] Invalid fragment encoding.
- [x] Invalid fragment.
- [x] Invalid JSON Pointer.

- [x] Missing graph source or target.
- [x] Root not found.
- [x] Duplicate/unused/unresolved reference.
- [x] Invalid resolved value.
- [x] Content identity conflict.
- [x] Target revision mismatch.
- [x] Representation selector required/invalid.
- [ ] Diagnose {$ref: value, extraKey: value} as an invalid marker or
explicitly document it as ordinary data.
- [x] Collect all bad references and targets instead of stopping at the
first graph failure.
- [x] Validate references from the editor and MCP file tools, not only
query compilation.
- [x] Map graph compilation/resolution, Markdown-document, and
JSON-document errors to exact structured Diagnostics rows.
- [x] Prevent an unrelated file's graph error or duplicate canonical URL
from blocking an exact-file query.
- [ ] Prove missing targets, cycles, bad representations, and bad JSON
paths through real MCP.

## Query request and structure

- [x] No selected output.
- [x] Negative, fractional, or over-1,000 limit.
- [x] Negative, fractional, or over-1,000 offset.
- [x] Invalid content mode.
- [x] Invalid full/markdown-body-ref maxBytes outside 1..1 MiB.
- [x] Invalid range offset/length or range over 256 KiB.
- [x] Empty or over-255-character index revision.
- [x] Multiple simultaneous schema issues retain exact query paths.
- [x] Make content option objects strict; unknown keys are currently
stripped.
- [x] Show an invalid persisted resource body rather than silently
loading the default query.
- [x] Aggregate unknown-key errors with every other structural issue;
MCP currently stops at the first unsupported key.
- [x] Add field-value type validation, for example reject size gt
"large" and id contains {}.
- [x] Warn about unobserved dynamic fields selected only as output.
- [ ] Prove the full structural matrix through the MCP server/API end to

- [x] Add a matrix for same-file multiple errors, multiple files,
outside-page errors, filter-only candidate files, and unrelated queries.

## Transport, authorization, cancellation, and internal failures

- [x] UNAUTHORIZED and FORBIDDEN.
- [x] REQUEST_CANCELLED in query HTTP paths.
- [x] Sanitized authenticated internal message.
- [x] Generic unauthenticated/public internal message.
- [x] Preserve structured causes for document-load HTTP
status/body/metadata failures.
- [x] Preserve structured causes for object-storage read failures.
- [x] Preserve structured causes for graph selection/assembly failures.
- [ ] Test MCP/API cancellation directly.
- [ ] Reproduce authorization, cancellation, storage, and

- [x] Prove failed post-commit MCP feedback reports whether a mutation
committed and returns enough identity for cleanup.

## Real MCP recheck and follow-up fixes (2026-09-03)

Ran the branch CLI against the PR preview backend. The first run exposed
that the saved CLI origin pointed to a different backend, so those
results were discarded. Every MCP result below came from the PR preview.
All temporary remote and local fixtures were removed afterward. The
failures found in that run were then fixed and covered by regression
tests.

- [x] Exact broken Markdown query returns FRONTMATTER_INVALID with
severity, filename, message, line, and column.
- [x] Exact MDX query returns unsafe-mdx with severity, filename,
message, line, and column.
- [x] A no-extension query returns warnings from both matching Markdown
and MDX files.
- [x] A Markdown-only query excludes the unrelated MDX warning.
- [x] Two fatal MDX files inside the returned page are both reported;
matching warnings remain attached.
- [x] Structural query validation returns three independent errors with
exact paths in one call.
- [x] Semantic query validation returns three fatal operator errors and
two warnings with exact paths in one call.
- [x] MCP upload, update, download, and exact-file query return multiple
source diagnostics for the same MDX source.
- [x] Query preview reports a missing Asset reference as ASSET_NOT_FOUND
with the source file and reference.
- [x] All temporary MCP fixtures were deleted and the saved CLI
connection was restored.
- [x] Fixed after recheck: validate every matching file before
pagination, including broken files outside the returned page.
- [x] Fixed after recheck: unrelated graph failures no longer block an
exact-file query.
- [x] Fixed after recheck: update, download, editor, and query paths use
shared reference validation.
- [x] Fixed after recheck: graph failures map to structured diagnostics
with the exact file.
- [x] Fixed after recheck: shared fatal UTF-8 validation runs before
upload writes and preserves structured error identity.
- [x] Fixed after recheck: MCP rejects filename/format mismatches.
- [x] Fixed after recheck: MDX validation keeps sibling and nested
warnings around unsupported components.
- [x] Fixed after recheck: MCP preserves stable top-level error codes
and structured details.
- [x] Fixed after recheck: query and MCP serializers preserve full
normalized diagnostic fields.
- [x] Fixed after recheck: unknown keys are aggregated with all other
structural query errors.
- [x] Fixed after recheck: shared query validation covers literal types,
output-only fields, and strict content options.
- [x] Fixed after recheck: unavailable selected content returns an
exact-file diagnostic instead of a silent empty result.

## Tests and delivery

- [x] Full Builder suite: 2,707 tests.
- [x] Content Engine suite: 445 tests.
- [x] Asset uploader suite: 211 tests.
- [x] Project runtime/MCP targeted suite: 128 tests.
- [x] CLI/MCP suite: 1,051 tests.
- [x] Relevant package typechecks, lint, generated docs, and diff
checks.
- [x] Documentation impact reviewed and generated Content Engine/MCP
reference updated.
- [x] Add the missing cross-surface error matrix described above.
- [ ] Demonstrate red/green behavior for every new matrix case.
- [ ] Run the complete agent evaluation suite after explicit approval.
- [ ] Re-run all checks after the remaining checklist is implemented.

## Compatibility and risk

Normal query result and expression-binding shapes remain unchanged.
Diagnostics add optional fields. Existing public/pre-auth error
redaction remains intact. The remaining unchecked items are broader
exhaustive real-MCP coverage, parser-recovery limits, candidate-warning
labeling, cancellation coverage, and agent evaluations.

Oleg Isonen 0ffdf36665 fix: Explain dynamic Content Block asset sources (#6333)
## Summary

Content Block source operations now explain how to resolve a dynamic
Assets resource for one rendered occurrence. A caller can keep the
persisted expression, supply the concrete resource result through
`variables`, and receive safe structured diagnostics when the expression
does not resolve to a non-empty MDX Asset id.

The operation still does not load page routes or resource results
itself. That work remains in the rendering or caller context.

## Checklist

- [x] Reproduce the unresolved result-one Assets resource expression
- [x] Preserve the dynamic source expression while validating a concrete
Asset id
- [x] Return the evaluated value shape without exposing supplied values
- [x] Reuse the shared Content Block source resolver
- [x] Describe `renderScope` and `variables` in the operation schema
- [x] Add a result-one Assets resource example
- [x] Verify connection keeps the dynamic expression after resolving the
supplied result
- [x] Add regression coverage for structured unresolved-source
diagnostics
- [x] Regenerate runtime contracts and CLI documentation
- [x] Review fixture impact: fixture inputs and outputs are not affected
- [x] Review documentation impact: MCP and CLI guidance are updated

## Verification

- New diagnostic regression failed against the old generic error and
passed with this fix
- Project Build: 88 files, 2,284 tests passed
- Project Build typecheck
- CLI typecheck
- Generated documentation and contract checks
- Formatting and lint with warnings denied
- Full CLI suite from the implementation review: 66 files, 1,038 tests
passed

Agent evaluations were not run because they require separate explicit
approval.

Oleg Isonen 2e4efb52f9 docs: update Link target values (#6326)
## Summary

Update the Link documentation to match the current code.

The Builder uses `_self`, `_blank`, `_parent`, and `_top` as the Link
`target` values. The old docs described these as `Self`, `Blank`,
`Parent`, and `Top`, which could make setting a new-tab link confusing.

## Changes

- Document the four current target values.
- Explain that `_blank` opens a link in a new tab or window.
- Remove the outdated Target screenshot.
- Checked the rest of `docs/` for the same outdated target names; no
other related occurrences were found.

## Verification

- `git diff --check` passed.
- Confirmed the values in
`packages/sdk-components-react/src/__generated__/link.props.ts` and
`packages/sdk-components-react/src/create-link.tsx`.
- Checked that the docs file and navigation file exist.
- `pnpm exec oxfmt --check docs/university/core-components/link.md` did
not run because the Markdown file is excluded by the formatter
configuration.

## Checklist

- [x] Review the current Builder implementation.
- [x] Review the authoritative docs page.
- [x] Check for similar outdated documentation.
- [x] Review documentation impact: this PR updates the affected page; no
other docs need changes.
- [ ] Merge the pull request.

Oleg Isonen 75840a119c fix: Start previews and diagnose runtime failures (#6321)
## Summary

Preview startup now binds loopback directly instead of scanning network
interfaces first. MCP no longer exposes or accepts a fixed preview host
or port: the CLI asks the operating system for an available loopback
port and returns the resulting URL.

The CLI also returns safe, structured diagnostics when the runtime
blocks preview networking or Chromium IPC, when generated IDs collide,
and when a listening preview fails its HTTP readiness probe. Preview
startup retries only a genuine automatic-port race; HTTP and connection
failures return immediately instead of repeating the full startup
timeout five times.

## Issue checklist

- [x] #6318 — reproduced the `uv_interface_addresses` failure, replaced
interface discovery with a direct TCP bind, and added a regression test
for the exact failure.
- [x] #6319 — reproduced Chromium aborting before DevTools startup when
the managed runtime blocks browser IPC/socket operations. The host
restriction cannot be bypassed by the CLI, but future reports now
include a safe `browser_ipc_permission_denied` issue without raw stderr,
paths, or tokens.
- [x] #6320 — ran four reported insert variants sequentially across two
pages; all generated unique IDs. Future collision errors now include the
affected namespace and insertion stage without exposing the generated
ID.
- [x] #6324 — reproduced the generic readiness timeout with a real
generated preview whose root probe returned HTTP 500 after the server
printed its Local URL. The MCP contract and documentation also allowed
agents to force a busy port; network binding is now runner-owned.
- [x] #6325 — confirmed the responsive screenshot uses the same
readiness path. Future reports distinguish HTTP, refused-connection,
timeout, and permission failures, non-port failures are no longer
retried, and screenshots cannot request a fixed preview port.
- [x] Documentation impact reviewed. Updated MCP examples and vision
guidance to omit runner-owned host and port fields.

## Technical notes

- Removes the CLI's direct `get-port` dependency. That package calls
`os.networkInterfaces()` even when a host is supplied.
- Binds `{ host: "127.0.0.1", port: 0 }`, reads the assigned TCP port,
then closes the temporary server.
- Removes `host` and `port` from MCP preview and screenshot input
schemas and rejects those fields at runtime.
- Returns the selected preview URL from `preview.start`; managed
screenshots reuse that active target.
- Returns `PREVIEW_NETWORK_RESTRICTED` with a stable
`network_permission_denied` issue when the OS rejects loopback binding.
- Reads at most the last 4 KB of Chromium startup stderr, maps only the
reproduced IPC/socket denial to a safe diagnostic, and discards the
buffer after startup.
- Preserves browser startup issues through CLI browser fallback
aggregation and the MCP screenshot error boundary.
- Reports generated record collisions with `generated_id_conflict`, the
namespace constraint, and the fragment insertion stage.
- Preserves structured readiness diagnostics when preview output is
appended.
- Reports HTTP 5xx and local connection failures without exposing raw
fetch errors.
- Retries with a newly allocated port only for `EADDRINUSE` /
`PREVIEW_PORT_IN_USE`.

## Verification

- [x] New regression tests were shown to fail before implementation and
pass afterward.
- [x] Reproduced the old generic timeout through the real preview
controller; after the fix, the same path returned `PREVIEW_HTTP_ERROR`
with `http_status:500`.
- [x] Verified MCP advertised and accepted fixed host/port fields before
the change, then rejected both fields after the change.
- [x] Preview readiness/controller tests: 2 files, 29 tests passed.
- [x] Vision tests: 13 files, 81 tests passed.
- [x] Project-build tests: 88 files, 2,282 tests passed.
- [x] CLI tests: 66 files, 1,038 tests passed.
- [x] Vision, project-build, and CLI typechecks passed.
- [x] Lint passed with warnings denied.
- [x] Package-boundary and MCP documentation checks passed.
- [x] Fixture impact reviewed; no fixture inputs or generated fixture
outputs are affected. Generated documentation was updated; the generated
runtime operation contract did not change.

Agent evaluations were not run because they require separate approval.

Oleg Isonen 7ff42abfb5 docs: Simplify MCP setup (#6311)
## Summary

- Add a short introduction with the only setup step: install the Codex
desktop app or Claude Desktop and ask it to install Webstudio CLI and
use MCP.
- Keep the existing generated reference below a divider.
- Remove documentation wording assertions across generators, CLI manuals
and help, MCP guidance, tool descriptions, and operation docs.
- Retain structured and executable coverage for command catalogs,
schemas, examples, runtime behavior, errors, and UI contracts.

## Implementation

The introduction lives in the MCP page template, and the generated
GitBook page is committed with it. Documentation prose is now free to
change without breaking tests; tests continue to cover machine-readable
contracts and observable behavior.

## Checklist

- [x] Add the concise introduction to the MCP template.
- [x] Regenerate the authoritative `docs/` page.
- [x] Audit the repository for documentation prose assertions.
- [x] Remove prose-only generator, manual, help, guidance,
schema-description, and operation-description assertions.
- [x] Preserve structured and executable contract coverage.
- [x] Review documentation impact: the existing MCP page is updated;
navigation and other documentation are unaffected.
- [x] Run targeted tests, typechecks, formatting, and lint checks.

## Verification

- CLI: 121 tests passed across the affected suites (119 in the sandboxed
run; 2 link tests passed separately with config-directory access).
- Project build: 513 tests passed.
- Protocol: 23 tests passed.
- Content engine reference: 1 test passed.
- `pnpm docs:mcp:typecheck`
- Typechecks for `webstudio`, `@webstudio-is/project-build`, and
`@webstudio-is/protocol`
- `oxlint --deny-warnings` on all changed TypeScript files
- `oxfmt` and `git diff --check`

## Compatibility and limitations

Documentation and test-only changes. No runtime behavior, schemas,
fixture inputs or outputs, or external integrations are affected.

Oleg Isonen 4a10645cb8 docs: Explain Builder themes and CSS warnings (#6298)
## Summary

- Document the shared System, Light, and Dark interface-theme preference
in the Dashboard and Builder guides.
- Distinguish the Webstudio interface theme from the authored site's
color scheme.
- Explain experimental, nonstandard, and obsolete CSS property warnings
in the Advanced Style panel.
- Add focused, matching light- and dark-theme screenshots of the
released Dashboard controls.

## Implementation

The Dashboard guide owns the screenshot and complete theme explanation.
The Builder anatomy guide documents the Builder menu path and links to
that canonical section. The screenshot pair was captured from the
released interface, cropped to the smallest useful region, and excludes
account identity.

## Checklist

- [x] Document the Dashboard theme path and available preferences.
- [x] Document the Builder theme path and canvas-theme boundary.
- [x] Explain CSS property status warnings and MDN compatibility
details.
- [x] Capture and visually review matching light/dark screenshots.
- [x] Review documentation impact and update all affected authoritative
`docs/` pages.
- [x] Verify internal anchors, asset references, image formats, and the
final diff.

## Verification

- `git diff --check` — passed.
- Screenshot assets — verified as 366×100 PNG files with equivalent UI
state and no account identity.
- Referenced files and `#interface-theme` / `#example-dark-mode` anchors
— verified.
- Repository formatter — not applicable; `oxfmt` excludes these
documentation targets.
- Tests — not run; documentation and screenshot assets only.
- Fixture inputs and generated outputs — unaffected.

## Known limitations

None.

Oleg Isonen 9ec4c820e1 fix: Use writable npm cache for previews (#6272)
## Summary

- Use a writable `.webstudio/preview/.npm-cache` for npm preview
installs when `npm_config_cache` is not explicitly configured.
- Preserve explicit npm cache settings and pnpm behavior.
- Document a safe recovery path that requires no cache deletion.

This removes preview startup failures caused by an unwritable default
npm cache. Initial dependency installation and its network/download cost
still remain when preview dependencies are not already installed.

## Technical choices

- Keep the cache beside the isolated generated preview because that
directory is already writable and reused across regenerations.
- Let an explicit `npm_config_cache` continue to take precedence.
- Do not retry arbitrary install failures or classify package-manager
prose.

## Todo

- [x] Reproduce npm dependency installation against an unwritable cache
before changing code.
- [x] Reproduce #6274 at the same dependency-install stage used by
session-backed screenshots.
- [x] Demonstrate the regression assertion failing before the fix and
passing afterward.
- [x] Use the preview-local cache only for npm without an explicit
cache.
- [x] Preserve explicit npm cache configuration and pnpm behavior.
- [x] Verify the real dependency installer against an unwritable project
npm cache.
- [x] Verify session-backed screenshot flow proceeds from successful
preview preparation to browser capture.
- [x] Review documentation impact and update the CLI manual plus
generated MCP documentation.
- [x] Review fixture impact; no project fixture inputs or outputs are
affected.
- [x] Review the final diff for correctness, duplication, and
unnecessary complexity.

## Verification

- Actual npm install reproduced #6269 and #6274 with `EPERM` against an
unwritable cache.
- Real preview dependency installation passed after the fix while
project npm configuration still pointed at that cache.
- Fail-before/pass-after regression demonstrated.
- `pnpm --filter webstudio test` — 65 files, 1,044 tests passed.
- `pnpm --filter webstudio typecheck`
- `pnpm lint`
- `pnpm check:generated-docs`
- Formatting and diff checks passed.
- GitHub CI after rebasing onto current `main` — 30 checks passed, 7
skipped, no failures.
- Agent evaluations were not run because they require separate explicit
approval.

Oleg Isonen 1b48716ff4 docs: Document MDX-backed Content Blocks (#6273)
## Summary

- Document how people create, connect, edit, validate, and publish
MDX-backed Content Blocks.
- Document the complete MCP workflow, including scoped expression
sources, frontmatter updates, diagnostics, conflicts, and disconnect
behavior.
- Add two focused screenshots for the human workflow.
- Fix issues found by a low-reasoning MCP agent while executing every
documented workflow.

Ref #6182

## Implementation notes

- Connection confirmation uses the public `confirmReplacement` field
because `confirm` is reserved as a hidden transport field.
- MCP edits frontmatter with `update-content-block-frontmatter`;
materialized MDX elements are not persistent targets for generic
instance mutation tools.
- Reload now intentionally discards a conflicted local source and
accepts the Asset's latest storage revision before an edit is reapplied.
- Generated MCP documentation and runtime contracts are updated from
their source files.

## Checklist

- [x] Document the human MDX Content Block workflow.
- [x] Document MCP discovery, connection, editing, diagnostics,
frontmatter, dynamic sources, conflicts, and disconnection.
- [x] Add only screenshots that clarify otherwise hard-to-describe UI
steps.
- [x] Test every documented MDX capability through the local MCP CLI
with a low-reasoning agent.
- [x] Reproduce and fix the replacement-confirmation schema mismatch.
- [x] Reproduce and fix persistent-session conflict reload and reapply.
- [x] Add regression tests that failed before each product fix and pass
afterward.
- [x] Regenerate runtime contracts and generated MCP documentation.
- [x] Review authoritative `docs/` content and update affected pages.
- [x] Run affected tests, typechecks, formatting, and diff checks.

## Verification

- Project Build: 208 affected tests passed.
- Content Engine Asset session: 8 tests passed.
- CLI documentation tests: 14 tests passed.
- MCP docs generator: 3 tests passed.
- Content Engine, Project Build, CLI, and MCP docs typechecks passed.
- `pnpm oxfmt --check` passed.
- `git diff --check` passed.
- Low-reasoning MCP evaluation passed all documented workflows,
including a real two-client revision conflict, reload, reapply, and
final saved inspection.

Oleg Isonen f6c524572d feat: add Builder dark theme and rebuild colors
## Summary

Rebuilds Webstudio’s color system, migrates the entire Builder to it,
and introduces a complete dark theme.

A small set of theme colors and contrast controls now drives the
interface through relative CSS colors:

```text
Theme colors and contrast
    ↓
Light/dark derivation bounds
    ↓
Derived color families
    ↓
Reusable semantic colors
    ↓
Component composition
    ↓
Builder interface
```

CSS is the runtime source of truth. Light and dark modes share the same
theme inputs, so changing a theme color automatically updates its
surfaces, content, borders, states, and component presentation. The
refactor turns dark mode into a first-class Builder theme rather than a
separately maintained palette.

This is an atomic migration. Legacy color names and compatibility
aliases will not remain after all consumers have moved.

## Scope

- The color source, derivation model, semantic vocabulary, validation,
typing, and Storybook overview.
- Every design-system component.
- Builder, dashboard, authentication, shared UI, Query Builder, stories,
and tests that consume the legacy color scale.
- Removal of the legacy Stitches color scale after its final consumer is
migrated.
- A complete dark theme across application UI while keeping authored
canvas content independent.
- Complete light and dark visual verification.
- Unified browser-test infrastructure: Vitest Browser Mode for Design
System browser contracts and standard Playwright Test for all Builder
E2E workflows.

Literal colors remain only where color is the actual content or belongs
to a deliberately separate system, such as user-authored values,
external previews, brand artwork, data visualization, functional canvas
overlays, and source assets. Every remaining exception must have an
explicit owner.

## Architecture decisions

- Theme authors control six color families and three bounded contrast
controls.
- Relative CSS colors derive the rest of the system.
- Dark mode changes derivation bounds instead of maintaining a second
independent palette.
- Components consume a small reusable semantic vocabulary.
- Component states and exceptional presentation are composed inside
components.
- Builder-specific categorical meaning uses focused composite recipes,
not intent semantics or a larger global vocabulary.
- TypeScript validates public semantic CSS-variable names but does not
generate runtime colors.
- No token-manager dependency, compatibility aliases, or
component-specific public color tokens.
- A new semantic or theme variable is added only when existing semantics
and local composition cannot represent a reusable cross-feature
decision.

## Todo

### Color-system foundation

- [x] Establish direct CSS as the runtime source of truth.
- [x] Define bounded theme colors and contrast controls.
- [x] Derive light and dark modes from the same theme inputs.
- [x] Reduce the semantic inventory to reusable decisions and explicit
accessibility pairs.
- [x] Generate only TypeScript names for public semantic CSS variables.
- [x] Validate layers, references, cycles, consumption, naming,
generated types, and browser-computed contrast.
- [x] Add the Storybook color-system overview and theme controls.
- [x] Document the architecture and its relationship to the public Craft
specification.

### Design-system migration

- [x] Replace every active legacy color consumer in design-system
components and Storybook chrome.
- [x] Compose component states locally without component-specific public
tokens.
- [x] Preserve intentional preview and sample-content colors.
- [x] Add complete positive, negative, warning, informative, and accent
accessibility pairings.
- [x] Validate light and dark scheme-bound references independently.
- [x] Verify the design-system package with typecheck, lint, formatting,
Storybook, and 222 tests.

### Inventory and contract

- [x] Inventory all 319 legacy references across 107 Builder, Query
Builder, story, test, and design-system files.
- [x] Classify every reference as a direct semantic replacement, local
composite recipe, documented literal exception, or removable code.
- [x] Record the intentional authored-content, external-preview,
functional-preview, data-visualization, brand, and source-asset
exceptions.
- [x] Treat the public semantic vocabulary as closed by default and
justify any proposed addition by cross-feature reuse and accessibility
need.
- [x] Keep Builder code limited to typed public variables accepted by
`cssVar()`.

### Theme infrastructure

- [x] Add `system` (default), `light`, and `dark` application
preferences.
- [x] Persist the preference in existing client settings and resolve
`system` through `matchMedia`.
- [x] Apply the resolved scheme before paint and respond to
operating-system changes.
- [x] Expose the persisted theme control under **View → Color scheme**.
- [x] Keep authored canvas documents independent from the application
theme.
- [x] Ensure portals, overlays, embedded surfaces, and third-party
controls receive the correct interface scheme.

### Generic interface migration

- [x] Migrate shared dialogs, project settings, notifications, controls,
and Query Builder.
- [x] Migrate dashboard, authentication, publishing, and shared
application UI.
- [x] Migrate the Builder loading state, topbar, sidebars, navigator,
workspace, footer, settings, pages, alerts, and menus.
- [x] Replace fixed interface literals alongside their owning surfaces.
- [x] Remove the old scrollbar variable and hardcoded loading color.

### Style panel and style-source recipes

- [x] Migrate ordinary style-panel inputs, labels, layouts, spacing,
alignment, menus, property states, and value editors.
- [x] Model style-source provenance, kind, interaction, and error as
separate axes.
- [x] Compose categorical style-source colors from neutral and
accent-relative colors.
- [x] Use negative semantics only for actual errors, not overwritten
provenance.
- [x] Reuse one feature-owned recipe across style-source controls,
badges, menus, and values without adding global tokens.

### Canvas and editors

- [x] Migrate canvas selection, reusable outlines, grid guides, resize
handles, labels, badges, and overlays.
- [x] Keep collaborator colors as data visualization while guaranteeing
readable labels.
- [x] Prevent Builder theme values from leaking into authored content.
- [x] Migrate editor surfaces, selections, autocomplete, lint states,
and tooltips.
- [x] Derive syntax visualization from neutral and accent-relative
colors; reserve intent colors for diagnostics.

### Explicit color domains

- [x] Isolate external search and social previews from the application
scheme.
- [x] Preserve user-authored CSS values, functional color previews, and
checkerboards.
- [x] Review brand surfaces independently in both schemes.
- [x] Document every retained literal in the exception ledger.

### Stories, tests, and legacy removal

- [x] Migrate all affected Builder stories and tests.
- [x] Replace the design-system test that intentionally references the
legacy scale.
- [x] Add theme-preference and scheme-resolution behavior tests.
- [x] Remove the legacy `design-tokens.color` registry.
- [x] Remove the Stitches `colors` scale and `rawTheme.colors`.
- [x] Remove color-name conversion code that exists only for the legacy
scale.
- [x] Add a focused repository check that rejects legacy references.
- [x] Confirm no compatibility mappings or deprecated aliases remain.

### Browser-test infrastructure

- [x] Run pure Design System tests in Node and browser-dependent tests
in Vitest Browser Mode with Playwright Chromium.
- [x] Migrate all 79 Builder E2E workflows from the custom harness to
standard Playwright Test.
- [x] Replace filename-based shard discovery with standard Playwright
sharding.
- [x] Preserve clean-backend shard retries and upload Playwright failure
artifacts in CI.
- [x] Remove the custom runner, registry, and timeout infrastructure.

### Verification and documentation

- [x] Compare light-mode visual regressions directly with `main`; review
every difference rather than accepting snapshots wholesale.
- [x] Add representative dark coverage for dashboard, Builder shell,
style panel, dialogs, editors, canvas tools, and status states.
- [x] Test default and extreme custom-theme presets.
- [x] Verify semantic and categorical-recipe contrast.
- [x] Test first paint, persistence, system changes, portals, and canvas
isolation.
- [x] Run affected tests, typechecks, lint, formatting, and Storybook
checks.
- [x] Review fixture impact; no fixture inputs or generated outputs are
affected.
- [x] Review authoritative `docs/` content and update it where needed.
- [x] Review the final diff and make this checklist reflect delivered
scope.

## Current verification

- Design-system typecheck and generated-type freshness: passed.
- Design-system tests: 222 passed, including the full theme-parameter
contrast sweep and browser component coverage.
- Builder typecheck and production build: passed.
- Theme preference and scheme-resolution tests: 10 passed.
- Scoped Oxlint, formatting, and diff checks: passed.
- Design-system Storybook build and representative light/dark visual
review: passed.
- Builder E2E: 80/80 Playwright entries passed (setup plus 79
workflows).

Oleg Isonen f9681dc30f feat: MDX-backed Content Blocks (#6234)
## Summary

Supersede #6182 with a clean implementation of MDX-backed Content Blocks
on top of the unchanged `main` Content Block editing model. A connected
`.mdx` Asset changes where authored children are loaded and saved; it
must not change how Content mode inserts, edits, selects, moves, copies,
or deletes instances.

The previous implementation remains available in
`agent/mdx-content-block-6124` and
`agent/mdx-content-block-6124-review`. Reuse its independently tested
parsers, converters, schemas, Asset repository, template resolution,
publication, MCP, and UI work where those pieces fit the corrected
architecture. Do not port its per-operation storage routing, projected
editing stores, MDX undo/history, or atomic multi-root machinery.

Ref #6124
Ref #6182
Closes #6261

## Locked behavior

- `.md` keeps its existing Markdown behavior; `.mdx` enables MDX.
- Standard Markdown structures are stored as Markdown. JSX is used only
for structures Markdown cannot represent losslessly.
- Generic elements use `<ws.element ws:tag="…">`; template instances use
`<ws.element ws:name="…">`.
- Invalid, unsafe, or unsupported MDX never prevents editing the file or
publishing the project. Builder and publication use the same recovery
result: recoverable nodes are skipped with source-located warnings,
while an unrecoverable document renders no authored file content in
either environment.
- Connecting a source never serializes existing Content Block children
into the file. **Connect** removes ordinary persisted children,
preserves Templates, sets `src`, and uses file content.
- Disconnecting resets `src`, discards derived instances, leaves the
Content Block empty, and never changes the Asset.
- While connected, normal Content Block mutations update in-memory
instances synchronously. Asset persistence happens afterward and never
blocks rendering.
- Genuine external revision conflicts use the standard reload-required
flow. Rapid local edits are ordered/coalesced and must never conflict
with each other.
- Repeated scopes use Content Block ID plus Collection item identity.
- Multiple Content Blocks may intentionally share one MDX Asset. They
share one revisioned document session and edits propagate to every
connected occurrence.
- Missing templates show warnings/placeholders only in Builder and are
skipped on published sites.

## Reuse strategy

- [x] Audit all 62 original implementation commits and 5 later
review/fix commits
- [x] Reuse the shared Content Engine Markdown/MDX AST, parser,
serializer, diagnostics, reference discovery, and tests
- [x] Reuse SDK source schemas, instance-name utilities, unique template
naming, and source-integrity validation
- [x] Reuse template resolution/materialization and authored-tree
conversion after removing storage-operation coupling
- [x] Reuse revisioned Asset content repository, authorization, limits,
and browser/server transport
- [x] Reuse publication, document-graph, CLI, MCP, source-control UI,
frontmatter UI, and E2E work where contracts remain valid
- [x] Reuse tests as behavioral specifications; rewrite tests that
assert the rejected projection/routing architecture
- [x] Do not port per-operation MDX routing, alternate projected
mutation stores, semantic reconciliation after each command, MDX Builder
history/undo, atomic multi-file rollback, or canvas loading/saving UI


## Old-branch porting map — do not rewrite

Before implementing any checklist batch, inspect the named
implementation and tests on `agent/mdx-content-block-6124-review`. Move
the implementation and its tests first; change only the boundary that
conflicts with the rebuilt architecture. Do not create a second
implementation under a new name. When a test encodes the rejected
projected-store architecture, retain its behavioral assertion and
replace only its setup.

### Already ported

`parseMdxDocument`, `serializeMdxDocument`, `preferMarkdownSyntax`,
`discoverMdxBodyAssetReferences`, `discoverMdxAssetReferences`, and

### Explicitly do not port

- `projectContentStorageChanges`, `createContentStorageProjection`,
`createContentStorageSelectorProjection`,
`executeContentStorageMutation`, `executeContentStorageTextReplacement`,
`executeContentStoragePropMutation`, and
`executeContentStorageStructuralMutation`
- `applyMdxContentStorageChanges` and `prepareMdxContentStorageWrites`;
replace them with one post-mutation snapshot serializer built from the
reusable pure `reconcileMdxAuthoredContent` converter
- `createContentBlockApplicationOperations` and the persistence-plan
wrappers that route individual editing commands
- Builder `$runtime*` projected stores, materialized mutation functions,
alternate selector/tree helpers, pending projected-change state, and
MDX-specific mutation sequences from `content-block-content.ts`
- Canvas loading/saving/open-file presentation state, MDX history/undo,
and atomic rollback machinery

## Implementation checklist

### 1. Preserve the `main` editing architecture

- [x] Keep normal synchronous insert, text, Enter, slash menu, property,
delete, move, wrap, copy/paste, selection, and focus mutations unchanged
- [x] Materialize connected content through the same runtime instance
interfaces used by ordinary Content Blocks
- [x] Keep connected authored children in memory and exclude them from
persisted build data
- [x] Route persistence only after a synchronous mutation has updated
the canvas
- [x] Never wait for Asset loading, conversion, or saving before
rendering an interaction
- [x] Add no MDX-specific implementation to individual editing commands

### 2. Shared Markdown and MDX conversion

- [x] Parse Markdown and the Markdown portion of MDX through one shared
AST and plugin configuration
- [x] Implement one shared MDX-to-instances converter and one shared
instances-to-MDX converter
- [x] Serialize headings, paragraphs, links, images, lists, tables, task
lists, blockquotes, thematic breaks, code, emphasis, strong,
strikethrough, and other supported GFM structures as Markdown
- [x] Serialize only non-lossless/custom structures as Webstudio JSX
- [x] Preserve nested Markdown in MDX elements, frontmatter, comments,
tight/loose list semantics, code whitespace, reference links, and Asset
references
- [x] Omit transient empty draft paragraphs instead of emitting
`<ws.element ws:tag="p" />`
- [x] Preserve unsupported source text and authored metadata whenever it
cannot be converted safely
- [x] Add deterministic round-trip and canonical-output coverage for
every supported Markdown structure

### 3. Invalid and unsafe MDX

- [x] Preserve file source exactly; never silently repair or rewrite
invalid source
- [x] Ignore imports, exports, expressions, executable JavaScript,
invalid properties, and other unsupported nodes when they can be
isolated
- [x] Continue rendering valid siblings and report every skipped subtree
once with filename, line, and column
- [x] Use the same recovery pipeline in Builder and publication so both
render the same authored result for the current file revision
- [x] When structural syntax prevents recovery, render no authored file
content in Builder or publication instead of retaining a stale
materialization
- [x] Skip an unrecoverable Content Block on published sites and
continue the build with a warning
- [x] Keep invalid and unsafe files editable and reconnectable
- [x] Enforce UTF-8, byte-size, depth, node-count, property-count, and
generated-output limits with source-located diagnostics where possible

### 4. File formats and Asset creation

- [x] Keep `.md` parsing and raw-HTML behavior unchanged
- [x] Support creating, opening, editing, deleting, and recreating
`.mdx` files through the normal text-file UI
- [x] Open `.mdx` in the same editor experience as `.md`
- [x] Always create an independent empty MDX Asset even when identical
empty files exist
- [x] Allow renaming `.md` to `.mdx` without converting or rewriting its
contents; after rename, handle invalid contents through the normal MDX
diagnostics and recovery pipeline
- [x] Update an already-open MDX editor immediately after canvas
persistence
- [x] Bound read/write buffering and verify the returned Asset identity
and revision

### 5. Source contracts and lifecycle

- [x] Support direct Asset bindings and dynamic expression bindings
- [x] Keep source mutation controls available only in Design mode; show
the connected filename and **Open** action read-only in Content mode
- [x] Reject duplicate source props, unsupported prop types, missing
Assets, non-MDX Assets, and unauthorized Assets
- [x] Analyze selected file diagnostics before confirmation without
modifying the block or file; MDX syntax diagnostics do not block
connection
- [x] For a non-empty block, show **Abort** and **Connect** and explain
that ordinary children will be replaced
- [x] On connect, remove every non-template child, preserve Templates,
set `src`, and materialize file content
- [x] Replace disconnect handoff with normal `src` reset; discard
derived content and leave the block empty
- [x] Remove disconnect confirmation and conversion; resetting a
repeated binding leaves every occurrence empty
- [x] Switching sources validates/loads the target before replacing the
usable binding and leaves both files unchanged
- [x] Revalidate Asset revision and project version when confirmation is
submitted
- [x] Make repeated connect/disconnect operations idempotent
- [x] Prevent disposed, stale, or out-of-order loads from replacing the
newest source
- [x] Keep loading, saving, conflict, empty-file, and open-file actions
off canvas

### 6. Asynchronous persistence and conflicts

- [x] Snapshot the current in-memory authored root after normal
mutations
- [x] Serialize/coalesce rapid edits per resolved Asset and always
prepare against the latest local snapshot
- [x] Allow independent Assets to save concurrently without scope
leakage
- [x] Use one revisioned document session and one ordered save queue per
Asset, even when multiple Content Blocks or render scopes reference it
- [x] After a shared Asset changes, rematerialize every connected
occurrence without persisting their generated instances to project data
- [x] Pin the resolved Asset and exact loaded revision for each write
- [x] Recheck authorization immediately before storage
- [x] Ensure local queued edits never produce stale-revision conflicts
with each other
- [x] On a genuine external revision conflict, preserve local content,
stop writes, and enter the standard reload-required state
- [x] Keep failed non-conflicting writes retryable without discarding
local content
- [x] Finish already accepted persistence writes after a Content Block
unmounts or switches source
- [x] Cancel obsolete loads, materializations, and UI updates after
unmount, reload, or source switch
- [x] Dispose project-scoped roots, queues, parse caches, failure state,
generations, and session subscriptions when the Asset session is
replaced
- [x] Invalidate Asset resources and synchronize open file editors after
successful writes
- [x] Keep multi-root persistence ordered, serial, and non-atomic;
report partial completion without rollback
- [x] Do not add Asset-history undo/redo; native text-editor undo
remains local to the open editor

### 7. Content mode parity

- [x] Empty connected blocks remain selectable and expose the normal
Content-mode `+` affordance
- [x] First insertion renders immediately
- [x] Enter creates and focuses the next paragraph immediately
- [x] Slash commands work in newly created empty paragraphs
- [x] Deleting one selected instance deletes exactly that instance
- [x] Mouse and keyboard moves use the same operation and permissions
- [x] Preserve sibling reorder, nested reparenting, and moves between
editable Content Blocks where `main` permits them
- [x] Preserve content-editable props such as Link `href`
- [x] Preserve copy, paste, cut, multi-cut, wrapping, unwrapping, grid
insertion, selection, Navigator order, and canvas order
- [x] Cover mutation routing centrally, retain the full unconnected
Builder suite, and exercise representative connected interactions in
real Builder E2E

### 8. Template names and permissions

- [x] Resolve only exact user-facing names from the direct flat
Templates list
- [x] Enforce unique names within each Templates list
- [x] Reject duplicate names during rename with inline validation
- [x] Allocate unique names during insert, paste, duplicate, move, wrap,
and unwrap
- [x] Apply valid template properties using the same permissions as
Content mode
- [x] Preserve and warn about ignored design-only, invalid, or stale
properties
- [x] Preserve template shell provenance without serializing expanded
template internals
- [x] Generate deterministic materialized IDs from source identity,
render scope, and authored usage path so focus/selection survives saves
- [x] Warn before renaming or deleting referenced templates; files
remain unchanged
- [x] Provide shared AST-based rename/remove migration operations for
MCP-assisted multi-file cleanup

### 9. Scope, frontmatter, and diagnostics

- [x] Scope materialized content by Content Block ID plus exact
Collection-item/render context
- [x] Prevent repeated instances and dynamic candidates from leaking
generated IDs, template resolution, or diagnostics across scopes while
sharing the underlying Asset source and revision where applicable
- [x] Remove frontmatter editing from Settings; edit the exact YAML
through the MDX Asset file editor
- [x] Preserve the exact frontmatter source byte-for-byte during canvas
body saves
- [x] Route canvas body changes and complete-file editor saves through
one revisioned per-Asset coordinator
- [x] Show a source warning indicator in Settings and precise
source-located diagnostics in the Asset editor
- [x] Deduplicate repeated diagnostics without losing distinct locations
- [x] Keep unresolved-template placeholders selectable and accessible
only in Builder

### 10. Asset references, transfer, and integrity

- [x] Discover and rewrite Asset references in frontmatter, Markdown
links/images, and MDX properties
- [x] Preserve Asset references while editing unrelated content
- [x] Include referenced Asset and template revisions in
dependency/cache identity
- [x] Route referenced Assets through published URL rewriting
- [x] Validate Content Block source integrity during project import,
fragment/page transfer, copy/paste, build integrity, and pre-publish
audit
- [x] Allow multiple Content Blocks and dynamic render scopes to
reference the same MDX Asset without treating the connection as an
integrity error
- [x] Preserve Templates when copying a connected Content Block
- [x] Preserve direct and dynamic Content Block source bindings when
copying or pasting within the same project
- [x] When copying only one rendered Collection item, resolve that
item’s current MDX Asset and replace the copied Content Block’s dynamic
source with a direct binding to that same Asset
- [x] When copying an entire Collection, preserve the Collection, its
instances, and its dynamic source bindings
- [x] Preserve the complete MDX source and frontmatter by reference;
copying a connected block must not rewrite the shared file
- [x] During cross-project transfer, copy every discoverable distinct
bound MDX Asset and rewrite transferred bindings to the destination
Assets
- [x] If some cross-project dynamic candidates cannot be discovered or
copied, continue with successful copies, preserve what can be
represented safely, and warn about skipped candidates
- [x] Revalidate source revisions and the destination project before
applying a cross-project transfer
- [x] If cross-project Asset creation or project insertion fails, leave
the source project unchanged and clean up any newly reserved destination
Asset
- [x] Use the same transfer operation through Builder and MCP

### 11. Dynamic sources and publication

- [x] Resolve dynamic bindings once per render/save scope
- [x] Require finite, discoverable candidate sets for publication and
load no unrelated MDX
- [x] Warn and skip unbounded, missing, unreadable, malformed, or unsafe
sources without failing the complete build
- [x] Materialize only rendered Content Blocks; ignore Templates
definitions and `src` on non-Content-Block instances
- [x] Skip unresolved template subtrees while keeping valid siblings
- [x] Include selected template styles, fonts, resources, unresolved
names, and referenced Asset revisions in generated dependency output
- [x] Keep draft-only MDX Assets out of publication retention

### 12. Builder, MCP, CLI, and shared operations

- [x] Use the same converters, source lifecycle, revision checks,
persistence service, diagnostics, and template migrations in Builder and
MCP
- [x] Keep frontmatter editing file-based; retain whole-frontmatter
runtime operations only where compatibility requires them
- [x] Avoid Builder-only or MCP-only mutation/conversion implementations
- [x] Regenerate runtime/API contracts from their source definitions
- [x] Update CLI Content Engine reference and generated MCP
documentation

### 13. Verification and delivery

- [x] Add regression tests that reproduce failures from the previous
implementation, including double deletion and blocked rendering
- [x] Cover two Content Blocks sharing one Asset: edits from either
block serialize once, update both canvases, preserve scope-specific
Templates, and cannot overwrite a newer local snapshot
- [x] Verify new tests fail against the broken implementation and pass
with the corrected behavior
- [x] Run SDK, Content Engine, Asset Uploader, Project Build, Builder,
React SDK, CLI, Protocol, and HTTP Client affected suites and typechecks
- [x] Run real Builder E2E for source lifecycle, live file refresh,
empty insertion, Enter/slash focus, Link props, delete, keyboard
reorder, switching, disconnect, conflicts, unresolved templates, dynamic
sources, and repeated scopes
- [x] Regenerate shared project fixture bundles and verify a second
generation leaves the tree clean
- [x] Run lint, package boundaries, `pnpm oxfmt --check`, and `git diff
--check`
- [x] Review and update authoritative `docs/` content and navigation
- [ ] Run the complete agent evaluation suite — not run because it
requires separate explicit approval

### 14. Content-mode parity and disconnect handoff

- [x] Allow keyboard reordering in Content mode through the normal move
command while keeping the editable Content Block boundary
- [x] Let already accepted Asset writes drain independently before
resetting the source; disconnect does not load, flush, or convert the
file
- [x] Remove MDX-to-instance copying from disconnect
- [x] Reset `src`, remove the derived tree, and leave the ordinary
Content Block empty
- [x] Preserve automatic text-editor focus after inserting editable
content from the template menu
- [x] Remove Builder frontmatter-save UI and report complete-file save
failures through the Asset editor
- [x] Add regression coverage for keyboard movement, disconnect
teardown, source switching, insertion focus, and paragraph deletion
focus restoration
- [x] Run the complete six-scenario MDX Content Block Builder E2E suite

### 15. Final architecture review fixes

- [x] Keep one canonical ordered pending document per Asset so shared
Content Block occurrences cannot conflict with one another
- [x] Merge ordered local edits from different occurrences while
preserving text changes, insertions, deletions, and sibling reordering;
keep external revisions on the strict reload-required path
- [x] Centralize typed render-scope parsing, repeated-occurrence
detection, scoped variable lookup, and dynamic Asset resolution across
Canvas, Settings, source lifecycle, and copy/paste
- [x] Capture the owning Asset session when a save is accepted so normal
unmount/source-switch teardown cannot redirect or lose it
- [x] Dispose project-owned roots, queues, caches, generations, failure
state, and subscriptions when replacing the project Asset session
- [x] Add regression coverage for same-Asset edits from two occurrences,
same-node last-write ordering, structural reorder, insertion
preservation, scoped source resolution, and project cleanup
- [x] Re-run affected full unit suites, typechecks, production build,
static checks, and all six MDX Content Block Builder E2E scenarios


### 16. Final persistence and transfer hardening

- [x] Drain every accepted per-Asset edit before project-session
teardown while retaining the owning authorization context
- [x] Drain canvas serialization queues and revisioned Asset writes
before pre-publish audit and publication
- [x] Block publication on a queued serialization failure or Asset
revision conflict
- [x] Copy actual Asset bytes during cross-project paste, preserve MDX
reference names, rewrite direct and Collection-backed Asset IDs, and
clean up newly created Assets when insertion fails
- [x] Include every resolved dynamic MDX source when copying an entire
Collection and warn while preserving successful copies when individual
Assets cannot be transferred
- [x] Keep MDX editor save failures visible with retry and route
conflicts through the standard reload-required flow
- [x] Give keyboard nested reparenting the same editable Content Block
boundary used by pointer movement
- [x] Add regression coverage and rerun the complete Content Engine and
Builder unit suites plus type, lint, formatting, package-boundary, and
diff checks

## Current rebuild status

- The connected Content Block now owns one complete MDX document:
frontmatter feeds designed-shell bindings and the explicit Body outlet
owns the authored MDX body.
- Builder and published output resolve the same frontmatter document
graph, including nested document references and Asset references.
- Direct frontmatter text/property edits use the existing ordered
per-Asset session; referenced-document values remain file-owned.
- Repeated Collection occurrences keep isolated runtime shell/Body
identities and occurrence-specific document values.
- The local blog article layout has been upgraded to the document/Body
model and its bindings validate cleanly.
- Full affected package suites and typechecks pass; every new regression
was demonstrated fail/pass.
- `pnpm lint`, package boundaries, `pnpm oxfmt --check`, generated
API/docs checks, fixture builds, and `git diff --check` pass.
- Full fixture synchronization is blocked by the development API
rejecting this local CLI version before fixture generation; existing
fixture bundles build successfully.
- Complete agent evaluations remain pending explicit approval.

### 17. Treat Content Block source as a property

- [x] Declare Content Block `src` in component metadata as a Design-mode
initial property labeled **Source**
- [x] Add the short property description: “Create an .mdx file in
Assets, then select or bind it here.”
- [x] Accept only a direct Asset or an expression resolving to an Asset
ID; reject URL/string sources, missing Assets, and non-MDX Assets
- [x] Extract and reuse the Image-style Asset picker and binding
presentation without duplicating source-control UI
- [x] Render Source through the normal properties section and remove the
separate source-section placement and special `src` filtering
- [x] Route Source changes through Content Block connect, switch, and
disconnect lifecycle operations instead of generic prop updates
- [x] Keep connect confirmation, Open, diagnostics, and persistence
state attached to Source; remove frontmatter and disconnect UI
- [x] Add regression coverage for direct Assets, dynamic Asset bindings,
invalid resolved values, lifecycle operations, and Design/Content mode
visibility
- [x] Re-review authoritative `docs/` content for the Source-property UI
change and update it if required

### 18. Source property UX

- [x] Show one full-width bindable Connect .mdx file button while
disconnected
- [x] Show equal-width filename and Open buttons while connected
- [x] Switch files from the filename button through the source lifecycle
- [x] Override PropertyLabel reset and Alt-click with the disconnect
lifecycle
- [x] Preserve confirmation, pending, failure, repeated-scope, and
dynamic-source behavior
- [x] Add regression coverage for connect, switch, binding, reset, and
disconnect
- [x] Update Content Block documentation
- [x] Run affected tests, typecheck, lint, formatting, package
boundaries, and diff checks


### 19. Reduced file-owned frontmatter follow-up

This checklist supersedes the earlier structured-frontmatter and
disconnect-copy behavior. Frontmatter remains file-owned and is edited
only in the MDX Asset editor.

#### A. Remove structured frontmatter UI

- [x] Remove the JSON frontmatter editor and unused Builder
controller/state
- [x] Keep source mutation Design-mode-only; show connected Source
read-only in Content mode and allow authorized editors to open the
complete file
- [x] Retain runtime frontmatter APIs only where compatibility requires
them

#### B. Preserve source and separate validation

- [x] Preserve the exact frontmatter envelope during every canvas body
save without parsing/stringifying YAML
- [x] Preserve comments, ordering, quoting, whitespace, BOM, newline
style, delimiters, and invalid but closed YAML
- [x] Keep the existing unsupported-node/property MDX recovery; do not
add an ad hoc partial parser
- [x] Parse body and frontmatter independently so either valid half
remains usable
- [x] Keep bounded Asset-query frontmatter extraction unchanged
- [x] Treat structurally malformed MDX as having no safe body tree

#### C. Share Asset state with the raw editor

- [x] Route canvas and complete-file changes through one ordered,
non-blocking per-Asset coordinator
- [x] Update canvas and clean raw editors immediately from shared
in-memory source
- [x] Reject stale dirty-editor saves, preserve unsaved text, and
require reload; never force-overwrite
- [x] Drain accepted writes after source replacement/disconnect and
report background failures globally
- [x] Dispose sessions only after they have no consumers and no queued
work

#### D. Connect, replace, and disconnect

- [x] Load and diagnose before connect; block only
unreadable/unauthorized/non-MDX Assets
- [x] Show **Abort / Connect** for non-empty blocks, including
diagnostics and the recoverable-content warning
- [x] Set `src` and delete persisted children through one runtime
mutation
- [x] Switch to a loaded source without waiting for the previous Asset's
network save
- [x] Remove disconnect confirmation and conversion
- [x] Reset `src` immediately, discard the derived tree, leave the block
empty, and preserve the Asset
- [x] Resetting a bound source leaves every repeated occurrence empty

#### E. Dynamic and shared sources

- [x] Keep one source/revision state per Asset and a separate derived
instances tree per occurrence
- [x] Resolve Templates independently per Content Block and preserve
Builder-only missing-template placeholders
- [x] Resolve bound `src` from the selected Collection occurrence
- [x] Make **Open** use the occurrence's resolved Asset; update the
filename and disable Open when unresolved
- [x] Add direct/bound tests including Collection item A opening `a.mdx`
and item B opening `b.mdx`

#### F. Diagnostics, MCP, and publication

- [x] Show an accessible warning icon beside Source with the first
diagnostic, line/column, and remaining count
- [x] Show precise YAML/MDX diagnostics in the Asset editor without
repetitive canvas/toast UI
- [x] Reuse parser/diagnostic/revision contracts in Builder, build,
publication, and MCP
- [x] Keep MCP frontmatter editing file-based and return structured
diagnostics for complete-source writes
- [x] Emit build warnings; published sites skip invalid/unsupported
content without diagnostic UI

#### G. Verification and documentation

- [x] Add fail/pass regressions for source preservation, independent
validation, stale raw saves, lifecycle, dynamic Open, shared Assets, and
cleanup
- [x] Run affected tests, typechecks, lint, formatting, package
boundaries, fixtures, and diff checks
- [x] Open Markdown and MDX editors at twice the default dialog size
with the right-side preview visible initially
- [x] Document canvas body editing, file-owned frontmatter, Content-mode
Asset access, and cloning an MDX Asset for a new post
- [x] Perform a final correctness, data-loss, DRY, simplification,
accessibility, and performance review
- [x] Keep this checklist synchronized with implementation status

### 20. Content-mode component properties

- [x] Show a connected Content Block Source read-only in Content mode
with an active **Open** action
- [x] Keep source switching, binding, reset, and disconnect available
only in Design mode
- [x] Expose HTML Embed code and preserve Code Text's code-editor
metadata on authored Text Content
- [x] Audit every registered component and expose authored payload while
keeping design, structure, and behavior controls in Design mode
- [x] Keep media dimensions and Code Text theme Design-only while
preserving adapter-owned intrinsic Image metadata during MDX round trips
- [x] Add exact component-permission and regression coverage
- [x] Update authoritative component documentation
- [x] Run affected full suites, typechecks, formatting, lint, package
boundaries, and generated contract/documentation checks


### 21. Designed document shell and Body outlet

- [x] Add one structural **Content Block Body** outlet and keep legacy
Content Blocks without it compatible
- [x] Materialize and persist only `document.body` children through the
Body outlet while preserving the surrounding designed shell and
Templates
- [x] Expose the connected document frontmatter through a Content Block
`document` parameter for shell text and property bindings
- [x] Write direct frontmatter-bound text and properties back through
the same ordered per-Asset session without blocking canvas mutations
- [x] Resolve document `$ref` dependencies and Asset references
consistently in Builder and published output
- [x] Keep referenced-document values read-only on canvas and direct
editors to the referenced file
- [x] Isolate repeated Collection occurrences while retaining
occurrence-specific source, frontmatter, shell, and Body content
- [x] Render the same designed shell, frontmatter values, and Body
substitution in generated/published output
- [x] Upgrade the local blog article layout to bind title, excerpt,
dates, author data, and images from frontmatter and render MDX through
Body
- [x] Add fail/pass regressions for nested Body discovery, lifecycle,
permissions, repeated values, document references, and generated shell
rendering
- [x] Update authoritative Content Block documentation
- [x] Run affected tests and typechecks, formatting, lint, package
boundaries, generated API/docs checks, and fixture builds


### 22. Final nested references and frontmatter editing

- [x] Keep direct frontmatter-bound text and property controls editable
in Content mode without exposing or replacing their bindings
- [x] Keep referenced-document values read-only and preserve legacy
instance-property name normalization
- [x] Render direct frontmatter text bindings through the plain-text
editing path
- [x] Resolve nested legacy and structured Asset references from
referenced Markdown/MDX frontmatter
- [x] Preserve missing Asset references, emit structured
`ASSET_NOT_FOUND` diagnostics, and keep them out of the document graph
- [x] Add fail/pass regressions for the real Settings control and
root/nested missing Asset-reference cases
- [x] Fix exact Content Block selection after the Body node appears in
Navigator
- [x] Run full affected suites/typechecks, all six MDX Content Block E2E
scenarios, deterministic fixture builds, generated checks, lint,
formatting, package boundaries, and diff checks

### Before merge

- [x] Resolve #6261: Nested Asset references in referenced Markdown
frontmatter work consistently in Assets queries, previews, publication,
and static export


### 23. Explicit writable expression bindings

- [x] Add an explicit `readwrite` mode to expression bindings; existing
expressions remain read-only by default
- [x] Accept `readwrite` only for direct static member paths and
centralize their parsing and validation
- [x] Require the expression root to provide a writable data source;
initially support the connected Content Block document frontmatter
- [x] Update Content Block permissions, canvas text editing, and
property controls to require a valid writable binding
- [x] Persist direct frontmatter edits through the existing ordered
per-Asset session
- [x] Create new direct frontmatter bindings with `readwrite` mode and
migrate existing compatible bindings
- [x] Preserve writable mode through schemas, serialization, loading,
copy/paste, transfer, and export
- [x] Add fail/pass regressions for valid paths, derived expressions,
unsupported sources, permissions, persistence, and compatibility
- [x] Review authoritative `docs/` content and update it if the
persisted binding contract affects user-facing documentation
- [x] Reject unsafe frontmatter paths and reject `readwrite` bindings
outside a connected Content Block document
- [x] Preserve expression binding mode through the public HTTP client
and document the MCP authoring contract
- [x] Limit frontmatter value write-back to Content mode so Design mode
retains normal binding replacement/reset behavior
- [x] Keep bindings inside Templates and across nested Content Block
ownership boundaries read-only
- [x] Upgrade compatible legacy bindings even when the Content Block is
disconnected during migration
- [x] Run affected tests, typechecks, formatting, lint, package
boundaries, fixture checks, and `git diff --check`

Verification: full SDK (567), Project Build (2,277), and Builder (2,695)
suites pass, along with affected Expression, Migration, Template, HTTP
Client, and MCP suites; typechecks, lint, formatting, package
boundaries, and diff checks pass. Generated contracts are refreshed.
Fixture synchronization remains blocked before generation because the
development API rejects this local CLI version as incompatible. The
checked-in bundles pass the current Protocol suite and every fixture
build with the current bundle version.

Oleg Isonen 7e7c14868a fix: Preserve read-only guides and publish targets (#6266)
## Summary

- Route explicit read-only `meta.guide` requests to focused discovery
tools and exclude mutations, side-effecting session tools, broad design
context, and visual verification.
- Require explicit task scope, specialized workflow, authored-fragment
routing, and design-system reuse instead of inferring behavior from
brief prose.
- Persist the requested staging or production target in new SaaS
deployment records.
- Return the same target from publish list and job status, with
backward-compatible inference for historical records.

## Todo

- [x] Reproduce the read-only custom-code audit misrouting from #6262.
- [x] Add failing regressions and implement strict read-only routing.
- [x] Remove behavior-affecting prose inference from CLI/MCP guide
routing.
- [x] Reproduce the single-domain production target mismatch from #6263.
- [x] Add create-to-list/status regressions and persist the explicit
target.
- [x] Cover historical deployment records that predate the stored
target.
- [x] Verify production create → list → get-job through the staging
deployment.
- [x] Regenerate and verify project fixtures against the changed bundle
contract.
- [x] Review documentation impact and update the generated MCP manual.
- [x] Review the complete diff for correctness, compatibility,
duplication, and unnecessary complexity.

## Verification

- Real staging publish for #6263 — passed; create, list, and get-job
consistently reported `production` for a one-domain publish. The
supplied project has no custom domains, so the custom-domain variant was
not available. The job remained `pending` during this check.
- Real local CLI/MCP verification for #6262 — passed; no mutation or
side-effecting tools leaked.
- `pnpm --filter @webstudio-is/protocol test -- src/fixtures.test.ts` —
17 passed
- `pnpm -r fixtures:build` — passed for all eight fixtures
- `pnpm --filter @webstudio-is/project-build test` — 2,134 passed
- `pnpm --filter webstudio test` — 1,037 passed; the one payload-size
regression was fixed and its targeted test passed
- `pnpm --filter @webstudio-is/domain test` — 24 passed
- `pnpm --filter @webstudio-is/sdk test` — 519 passed
- Builder API router test — 30 passed
- Relevant package typechecks — passed
- `pnpm lint`
- `pnpm check:package-boundaries`
- `pnpm check:generated-api`
- `pnpm check:generated-docs`
- Regression tests were demonstrated failing against the previous
behavior and passing with the fixes.
- Agent evaluations were not run because they require separate explicit
approval.

Closes #6262

Oleg Isonen cbe4950cd0 fix: Use available package manager for previews (#6251)
## Summary

- Use the npm or pnpm launcher that started Webstudio for preview
dependency installation, builds, and server startup.
- Use pnpm-compatible isolated-install flags and report the selected
package-manager path on failure.
- Preserve the existing installed-dependency reuse path before
package-manager resolution.

## Technical choices

- Read the standard `npm_execpath` metadata already supplied by npm and
pnpm; users do not need to configure another environment variable.
- Run JavaScript launchers such as `pnpm.cjs` with the selected Node
runtime, supporting bundled Node distributions without adjacent npm.
- Keep the existing npx-to-npm mapping and fallback behavior unchanged.
- Distinguish numeric package-manager exit codes from process-launch
errors such as `ENOENT`.

## Todo

- [x] Reproduce the bundled Node + pnpm + missing adjacent npm failure.
- [x] Add fail-before/pass-after coverage for dependency installation,
production build, and preview startup.
- [x] Reuse the detected pnpm launcher.
- [x] Preserve installed-dependency reuse.
- [x] Include the selected launcher path in installation failures.
- [x] Report package-manager exits and process-launch errors accurately.
- [x] Review documentation impact and update the CLI manual plus
generated MCP documentation.
- [x] Review fixture impact; no fixture inputs or outputs are affected.

## Verification

- Focused install diagnostic regression suite — 28 tests passed.
- `pnpm --filter webstudio typecheck`
- `pnpm lint`
- `pnpm --filter webstudio test` — 1,029 of 1,030 tests passed; an
existing process-supervisor cleanup test hit a transient `ENOENT`, then
passed 4/4 when rerun in isolation.
- Generated documentation checks passed.
- Real pnpm JavaScript launcher invocation with isolated preview install
flags.

Oleg Isonen 981f45fd0d docs: Optimize documentation image sizes (#6253)
## Summary

Replace ten oversized PNG screenshots in the product documentation with
high-quality WebP assets and update their references.

The affected assets shrink from 27,813,051 bytes to 2,822,010 bytes (90%
smaller) while retaining their original pixel dimensions.

## Technical choices

- Encoded screenshots as WebP at quality 88 with sharp YUV conversion.
- Kept original dimensions to preserve UI text legibility and zoom
detail.
- Left animated GIFs unchanged: GIF-native optimization, palette
reduction, and resizing tests increased their file sizes, so changing
them would add cost or reduce clarity.
- Kept documentation content, navigation, and public page paths
unchanged.

## Checklist

1. [x] Audit raster assets in `docs/.gitbook/assets`.
2. [x] Optimize referenced PNG assets above 1 MB where conversion
materially reduces size.
3. [x] Update every affected documentation reference.
4. [x] Verify replacement dimensions and image decoding.
5. [x] Verify visual quality (SSIM 0.961–0.997 plus manual spot checks).
6. [x] Verify new references resolve and removed filenames are no longer
referenced.
7. [x] Review documentation impact; this PR changes documentation assets
and their direct references only.
8. [x] Verify no fixture inputs or generated fixture outputs are
affected.

## Verification

- `git diff --check`
- Reference checks for all ten added and removed filenames
- Pixel-dimension comparison for all ten replacements
- FFmpeg SSIM comparison for all ten replacements
- Manual visual review of representative full-resolution screenshots

The repository formatter excludes these documentation files, so it
reported no matching targets. Agent evaluations were not run because
this is a documentation-asset-only change.

Oleg Isonen 471f504087 feat: Select unused assets before deleting (#6245)
Closes #6243

## Summary

- Add checked-by-default controls for every asset in the **Delete unused
assets** dialog.
- Add a footer **Select all** control that reflects the complete
selection and toggles all assets.
- Delete only selected assets that remain unused and disable deletion
when the selection is empty.
- Keep the Assets documentation aligned with the selective deletion
workflow.

## Implementation

The dialog owns a set of selected asset IDs initialized from the
unused-assets result. Individual checkboxes update that set, while
**Select all** replaces it with either every currently unused ID or an
empty set.

Asset usage inputs remain subscribed while the dialog is open. The
deletion payload is intersected with the current unused-assets list, and
this cleanup path does not force deletion. If an asset becomes
referenced before the mutation executes, the runtime rejects its
deletion instead of removing a now-used asset.

## Todo

- [x] Add per-asset selection controls.
- [x] Add and position the **Select all** footer control.
- [x] Limit deletion to selected asset IDs that remain unused.
- [x] Protect against assets becoming referenced while the dialog is
open.
- [x] Add regression tests for individual selection, select-all
behavior, empty-selection protection, selective deletion, and live usage
changes.
- [x] Review documentation impact and update the Assets guides.
- [x] Verify formatting, lint, types, and Asset Manager/assets tests.

## Verification

- `pnpm --filter @webstudio-is/builder exec vitest run
app/builder/shared/asset-manager app/builder/shared/assets` — 26 files,
221 tests passed.
- `pnpm --filter @webstudio-is/builder typecheck` — passed.
- `pnpm exec oxlint --deny-warnings
apps/builder/app/builder/shared/assets/delete-assets.ts
apps/builder/app/builder/shared/asset-manager/delete-unused-assets.tsx

— passed.
- Both regression tests were confirmed failing before their respective
implementations and passing afterward.

## Compatibility and follow-ups

No data migrations, public API changes, fixture changes, or known
follow-ups.

Oleg Isonen db2175f333 fix: transfer pasted assets across deployments (#6228)
Closes #6227

## What changed

Cross-deployment copy/paste now transfers referenced assets into the
destination project before inserting instances, pages, templates, or
folders.

- Add optional source deployment metadata to the existing v0.1 clipboard
formats.
- Keep old v0.1 payloads readable and keep new payloads readable by
older builders, which ignore the additive field.
- Reuse the existing asset upload-by-URL flow for images, fonts, videos,
and files.
- Preserve source video dimensions through the existing upload route.
- Replace source asset IDs and font-family references with destination
values before runtime insertion.
- Include and remap page social images and marketplace thumbnails.
- Reject current clipboard payloads whose page metadata references
omitted assets.
- Leave the public `pageTransfer.insert` runtime input unchanged.
- Abort insertion with a paste error when an asset cannot be imported.

No clipboard version increase, custom network fetcher, address
blocklist, rollback framework, or global paste wrapper is introduced. If
a multi-asset import partially uploads before a later upload fails, the
completed uploads may remain unused.

## Checklist

- [x] Rebased onto `main`
- [x] Preserve the existing v0.1 clipboard format
- [x] Transfer and remap instance assets
- [x] Transfer and remap page, template, and folder assets
- [x] Preserve video metadata
- [x] Keep runtime page-transfer API compatible
- [x] Add regression coverage
- [x] Review documentation impact and update page-copy documentation
- [x] Run Builder tests and typecheck
- [x] Run project-build tests and typecheck
- [x] Run lint, package-boundary, and generated-API checks

## Verification

- Builder full suite: 219 files, 2,552 tests passed
- Project-build full suite: 78 files, 2,129 tests passed
- Final affected suite: 84 tests passed
- New regressions were confirmed failing before the fixes and passing
afterward
- Builder and project-build typechecks passed
- `pnpm lint` passed
- `pnpm check:package-boundaries` passed
- `pnpm check:generated-api` passed
- Fixture inputs and generated fixture bundles are unaffected

Oleg Isonen 9e504037fb fix: improve MCP reliability across project workflows (#6222)
## Summary

Fixes the reproducible MCP, preview, redirect, audit, mutation, and
asset-upload failures from the latest issue batch. Historical and
non-reproducible reports were investigated without speculative fixes.
Visual verification is now opt-in unless the user explicitly requests
it.

## Issue checklist

- [x] #6207 — report tested recovery when an explicitly selected browser
fails to start.
- [x] #6208 — accept generic and registered buttons as valid label
targets without requiring a separate form label.
- [x] #6209 — reject unknown style coordinates such as `breakpointId`
and document the supported `breakpoint` field.
- [x] #6210 — traced Node 18 access to CLI 0.293.0 predating the
launcher guard; closed as already fixed by #6201.
- [x] #6211 — verified the supported launcher blocks the reported Node
18 crypto path; closed as already fixed by #6201.
- [x] #6212 — give sequential responsive captures the sum of their
per-capture timeout budgets.
- [x] #6213 — keep preview install, build, and server subprocesses on
the parent CLI Node runtime.
- [x] #6214 — add safe confirmation and diagnostics for ambiguous
mutation responses; this does not claim to remove upstream latency.
- [x] #6215 — confirmed as the same historical Node 18 release path as
#6210; closed as already fixed by #6201.
- [x] #6216 — verified malformed input returns structured errors on
current main; closed as not reproducible and improved future failure
diagnostics.
- [x] #6217 — add transaction-id confirmation for large fragment
mutations after ambiguous 5xx responses; this does not make the
operation asynchronous.
- [x] #6218 — verified the existing DevTools reconnect fix from #6205;
closed as already fixed.
- [x] #6219 — preserve the incoming pathname and query when a redirect
target supplies only a hash.
- [x] #6220 — return ordered `uploaded`, `failed`, and `ambiguous`
results so partial asset successes are not lost or retried unsafely.
- [x] #6221 — verified parser recovery without a Node crash; closed as
not reproducible and improved future JSX failure diagnostics.
- [x] #6223 — verified browser-session reuse, reconnect, and cleanup;
closed as already fixed by #6205 after the reported CLI version.
- [x] #6224 — expose both text-asset sources and encode the exactly-one
requirement in the standard MCP schema.
- [x] #6225 — could not reproduce the project-specific upstream timeout;
closed with safe confirmation coverage and improved structured
diagnostics, without claiming a latency fix.
- [x] #6226 — could not reproduce the project-specific upstream timeout;
closed with safe confirmation coverage for insert-fragment, without
adding a speculative fragment-specific fix.
- [x] #6229 — reproduced the reported two-process sequence with the
current local CLI and a real browser; both captures passed, so the
0.293.0 report was closed without a speculative fix.
- [x] Require explicit user consent before preview, screenshots, diffs,
OCR, or rendered visual audits unless visual verification was requested.

## Technical notes

- Ambiguous mutation responses are confirmed only with the same
idempotent transaction id. If confirmation is also ambiguous, the
session reports `AMBIGUOUS_COMMIT`, refreshes state, and never replays a
fresh mutation.
- CLI error mapping retains the original remote error as a
non-enumerable cause, so JSON gateway status reaches the ambiguity
classifier without exposing raw remote context in serialized
diagnostics.
- Forced asset uploads are not automatically retried after an
unknown/network/5xx outcome. Batch results retain the original input
index, including duplicate filenames.
- Stable issue codes and constraints are retained for diagnostics.
Arbitrary validation paths, messages, argument values, project content,
and raw contextual data are excluded.
- The MCP handshake remains the source of tool input schemas;
goal-specific guides avoid duplicating those contracts and reduce
model-context cost.
- `update-asset-content` now exposes `path` and `content` with a
machine-readable `oneOf` constraint, matching the runtime rule that
exactly one source is required.
- Redirect targets with their own pathname or query still replace those
request components.
- Generated runtime contracts, CLI documentation, product documentation,
and deployment fixtures were regenerated from their sources.

## Verification

- [x] Three independent review/test agents exercised visual consent and
preview behavior; mutation, asset, and privacy behavior; and
accessibility, styles, and redirects.
- [x] `pnpm checks` passed after the final transport follow-up: all
workspace tests and typechecks, lint with warnings denied, package
boundaries, generated API contracts, generated docs and documentation
checks, and the complete fixture link/sync/build pipeline.
- [x] Changed-package suites passed, including Project Build (2,125
tests), HTTP client (42 tests), CLI, Protocol, and Builder.
- [x] Complete `pnpm evaluations` run on the preceding implementation
commit: all five real-world fixtures and every behavioral check passed.
Four baseline comparisons passed; one font-assets sample exceeded only
its model-output token allowance, and its isolated rerun passed.
Evaluations were not rerun after the final transport and schema
follow-ups because fresh approval is required.
- [x] Design evaluation MCP response bytes improved from the 39.8 KB
baseline to 37.6 KB after removing duplicated guide contracts.
- [x] Documentation impact reviewed; generated MCP docs and multi-file
upload guidance are updated.

Oleg Isonen 626b5e741b fix: Reduce discovery for authored fragments (#6203)
Ref #6177
Ref #6154

## Outcome

Bounded authored-fragment requests no longer receive broad
design/authentication context bundles, registry discovery, or
design-token operations through generic keyword matching.

The initial ProjectSession synchronization is unchanged. Focused target
reads, missing nested schemas, and expression guidance can still add
calls when the requested fragment requires them.

## Root cause

`meta.guide` treated the generic word `design` as visual intent and
allowed workflow-specific context bundle tools to enter ordinary
keyword-ranked recommendations. An authored component insertion could
therefore be classified as visual work and receive
`inspect-design-context` even without a supplied visual reference or a
request to reuse the project design system.

## Implementation

- Give specialized goal guides stable IDs and return structured routing
metadata with the matched workflow and broad context tools.
- Keep `inspect-auth-context` and `inspect-design-context` exclusive to
their specialized workflows.
- Treat Figma, screenshots, supplied designs, and explicit design-system
references as visual intent without treating every use of `design` as
visual work.
- Suppress component/template registry discovery for explicit
`insert-fragment` or authored-fragment requests.
- Suppress design-token operations for those requests unless the brief
explicitly asks for design-system or token reuse.
- Preserve the existing design-input workflow for Figma, screenshots,
and supplied designs.

## Todo

- [x] Add a regression test for the reported authored timer/component
workflow.
- [x] Demonstrate that the regression test fails before the routing fix
and passes afterward.
- [x] Preserve explicit design-input discovery and verification
behavior.
- [x] Add machine-readable workflow routing metadata.
- [x] Review documentation impact and update the authoritative MCP
manual plus generated GitBook output.
- [x] Review fixture impact; no fixture inputs or generated fixture
bundles are affected.
- [ ] Run the complete local agent evaluation suite. It was not run
because repository policy requires separate explicit approval and
approval was not provided.

## Verification

- Project-session MCP tests: 117 passed.
- Project-build and CLI typechecks passed.
- Targeted oxlint passed.
- Documentation generator tests and documentation typecheck passed.
- MCP documentation and CLI generated docs were regenerated twice with
stable hashes.
- `git diff --check` passed.

## Tradeoffs and limitations

- Brief classification remains deterministic intent matching; clients
still decide which recommended tools they actually call.
- The change prevents broad context tools from being recommended
generically but does not enforce a universal discovery-call limit.
- A fragment that genuinely needs existing tokens, unfamiliar
expressions, or unknown target structure can still require focused
discovery.
- No schema migration, project-data migration, or fixture regeneration
is required.

Oleg Isonen b2d62b2e49 fix: Restore scoped descendant selectors (#6195)
## Summary

Restore custom state selectors that target descendants of the selected
instance, including `:hover .button` and `:hover > .icon`.

The CSS engine already generated these selectors correctly. #5886
unintentionally rejected them while hardening MCP style inputs against
selectors that can escape instance scope.

## Technical choices

- Parse exactly one selector with `css-tree`.
- Require the selector to begin with a pseudo-class, pseudo-element, or
attribute state anchored to the selected instance.
- Allow only descendant and direct-child combinators after that anchor.
- Continue rejecting selector lists, unanchored type/class/ID selectors,
sibling combinators, unknown pseudo-selectors, and pseudo-elements used
as ancestors.
- Document CSS variables as the preferred parent-child interaction
pattern; use descendant selectors when selector-based targeting is
specifically required.

## Todo

- [x] Restore scoped descendant and direct-child selectors.
- [x] Preserve instance-scope protections.
- [x] Cover real authoring inputs and generated CSS.
- [x] Demonstrate new tests fail without the restored behavior and scope
guards.
- [x] Verify the reported workflow through the local CLI/MCP and
generated preview.
- [x] Review documentation impact and update the authoritative Builder
docs.
- [x] Verify generated API contracts remain current.

## Verification

- `pnpm --filter @webstudio-is/css-data test` — 4,623 passed, 1 skipped
- `pnpm --filter @webstudio-is/css-data typecheck`
- `pnpm --filter @webstudio-is/project-build exec vitest run
src/runtime/styles.test.ts src/runtime/audit.test.ts` — 198 passed
- `pnpm --filter @webstudio-is/project-build typecheck`
- `pnpm lint`
- `pnpm check:generated-api`
- Documentation targets and anchors verified
- Local MCP disposable-fixture workflow:
- Discovered `insert-fragment` and `update-styles` through MCP metadata.
  - Inserted a card with a descendant `<button class="button">`.
- Dry-run and committed `state: ":hover .button"`; `get-styles` returned
the persisted state.
- MCP preview generated `.chjrfuf:hover .button` while the card used the
`chjrfuf` instance class, proving the selector remained
instance-anchored.
  - Preview screenshot completed and returned HTTP 200.
- Agent evaluations were not run because the suite has no
custom-selector coverage

## Known limitation

Sibling combinators remain unsupported because they can select elements
outside the selected instance. Selector lists remain unsupported because
later list entries can escape the generated instance prefix.

Oleg Isonen 2df130171f feat: Resolve asset references as structured metadata (#6184)
## Summary

- add exact `$ref` asset values that resolve to Asset Manager metadata
- keep plain local asset paths returning URL strings for backward
compatibility
- derive reference metadata from the canonical asset object so newly
added asset fields flow through automatically
- let Assets query output fields select only the metadata returned,
including nested arrays
- carry the same resolved shape through preview, generated preview,
published runtime, and static export
- document the syntax and accessible image binding in Content Engine and
MCP docs

## Design

The source document declares only the relationship:

```yaml
featureImage:
  $ref: ./assets/hero.png
```

The Assets query controls projection with fields such as
`properties.featureImage.src` and `properties.featureImage.description`.
Selecting `properties.featureImage` returns the canonical Asset Manager
asset metadata together with the resolved `src`. The Content Engine
runtime contract accepts the canonical asset object instead of
maintaining a second metadata field list; `url` becomes `src`, and
internal `contentRef` is not exposed.

Plain strings retain their existing URL-string result. Existing document
`$ref` behavior is preserved by resolving structured asset metadata only
when the target is a known non-document asset.

## Verification

- [x] Content Engine full test suite: 298 tests
- [x] SDK full test suite: 517 tests
- [x] Asset repository tests: 39 tests
- [x] CLI prebuild tests: 58 tests
- [x] Content Engine, SDK, Asset Uploader, CLI, and Project Build
typechecks
- [x] Repository lint
- [x] Content Engine and MCP documentation generation and tests
- [x] Generated API check
- [x] Local fixture build and generated fixture update
- [x] New behavior tests demonstrated fail before/pass after the
implementation
- [ ] Complete fixture sync (development API currently rejects this
branch's newer CLI protocol; local fixture build passes)
- [ ] Agent evaluations (not run; require explicit approval)

## Checklist

- [x] Local structured references return field-selected metadata
- [x] Newly added canonical asset fields flow through without a Content
Engine whitelist change
- [x] Plain-path queries remain backward compatible
- [x] Nested object and array projection
- [x] External URL strings remain usable
- [x] Missing or null descriptions allow `??` fallback to the title
- [x] Expanded metadata counts toward query result-size limits
- [x] Documentation impact reviewed and Content Engine and MCP docs
updated
- [ ] Missing asset targets return a non-failing unresolved value and
dedicated diagnostic
- [ ] Apply the resource and Image binding changes to the separate
Webstudio blog project

## Known limitation

A `$ref` whose asset target no longer exists is not yet converted into
an unresolved asset value with a dedicated diagnostic. This PR
intentionally does not claim that acceptance criterion yet.

Oleg Isonen 5ec3547d36 fix: Support JSON content files in Builder (#6168)
## Summary

- make the complete asset filename editable in Asset settings
- convert existing editable text assets when their extension changes
while preserving the asset ID
- accept every JSON root type and normalize JSON-compatible syntax into
formatted strict JSON
- expose the same optional extension change through MCP/API
`update-asset-content`
- initialize new JSON files and empty text-to-JSON conversions with a
valid empty object
- distinguish browser URL imports from JSON file uploads so JSON objects
with a root `url` field remain file content
- update the Assets and Content Engine documentation

## Root cause

Asset settings rendered the extension as a fixed suffix outside the name
input. The metadata rename mutation could only change the display
basename, while content revisions always inherited the current storage
extension. As a result, changing `.md` to `.json` was impossible in the
UI and unavailable through the shared MCP/API revision command.

Asset settings now edits the complete filename. Ordinary renames keep
using the metadata mutation. A text-extension change loads the current
content, validates it for the target format, and writes a new immutable
revision through the existing conflict-safe content endpoint. The
existing Acorn-backed `parseJsonExpression` utility accepts
JSON-compatible syntax without evaluating code and serializes it as
strict JSON. Objects, arrays, strings, numbers, booleans, and `null` are
all accepted.

## Checklist

- [x] Create JSON files by entering a `.json` filename
- [x] Edit the complete filename in Asset settings
- [x] Convert editable text-file extensions while preserving the asset
ID
- [x] Expose extension conversion through `update-asset-content`
- [x] Create JSON files and convert empty text files with a valid empty
object
- [x] Normalize safe JSON-compatible syntax to strict JSON
- [x] Accept objects, arrays, and scalar JSON roots
- [x] Reject executable or incomplete content
- [x] Preserve browser-uploaded JSON object shapes
- [x] Review and update authoritative Builder documentation
- [x] Add focused UI, revision, HTTP-client, CLI/MCP, protocol, and
upload regression tests
- [x] Run affected typechecks, lint, documentation checks, and the
Builder production build
- [ ] Manually verify create, edit, rename `.md` to `.json`, reload
persistence, and Content Engine query in a browser
- [ ] Run the complete local agent evaluation suite if approved

## Verification

- 217 focused tests passed across Builder, asset revisions, HTTP client,
CLI/MCP, and protocol
- Builder, asset-uploader, HTTP-client, protocol, CLI, and project-build
typechecks passed
- Builder production build passed
- MCP and Content Engine documentation checks passed
- `oxlint` on changed TypeScript files passed
- `git diff --check` passed
- Regression tests were demonstrated failing before the implementation
and passing afterward

A disposable E2E database and PostgREST stack bootstrapped successfully
in the earlier real-path test, but UI automation remained blocked
because no controllable browser was available. Fixture inputs and
generated fixture outputs are not affected. Agent evaluations were not
run because approval is required and was not requested.

Oleg Isonen 81d5148046 fix: canonicalize trailing-slash page URLs (#6173)
## Outcome

Canonical page URLs now omit a trailing slash in Webstudio Cloud sites
and exported JavaScript applications. A request such as
`/about/?campaign=launch` receives a permanent `301` redirect to
`/about?campaign=launch`, preventing both URL variants from serving
identical page content.

The behavior is implemented once in the generated root redirect handler,
so it covers fixed and dynamic application routes without generating an
extra route per page. Exact project redirects remain authoritative.
Protocol-relative-looking paths such as `//example.com/` are left
untouched so canonicalization cannot become an external redirect.

Static exports cannot redirect requests themselves. Their URL behavior
remains host-specific and is documented for Cloudflare Pages, Netlify,
Vercel, and other static hosts.

## Implementation

- Add one shared pathname normalizer in the SDK.
- Apply canonicalization after exact authored redirect matching in both
generated application runtimes.
- Ignore repeated leading slashes before constructing a redirect
location.
- Extend redirect-loop detection to model the implicit canonical
redirect.
- Regenerate the affected fixture applications from their templates.
- Document application canonicalization and host-specific static export
behavior.

## Todo

1. [x] Add central trailing-slash canonicalization.
2. [x] Preserve query strings, encoded path segments, and the root path.
3. [x] Cover concrete dynamic URLs without per-route generation.
4. [x] Preserve explicit project redirect precedence.
5. [x] Detect redirect loops that pass through canonicalization.
6. [x] Prevent protocol-relative external redirects.
7. [x] Regenerate and review fixture output.
8. [x] Review documentation impact; document application and SSG
behavior.
9. [x] Run targeted and repository-level verification.

## Verification

- SDK tests: 548 passed
- SDK typecheck: passed
- Project Build tests: 2,379 passed
- Project Build typecheck: passed
- CLI tests: 997 passed; two tests timed out only while three package
suites ran concurrently, then both affected files passed in isolation
(6/6)
- Redirect regression suite after security follow-up: 302 passed
- CLI typecheck: passed
- `pnpm lint`: passed
- `pnpm check:package-boundaries`: passed
- `pnpm fixtures`: passed
- Documentation internal anchors and Markdown whitespace: checked
- New regression tests were confirmed failing before their
implementations and passing afterward
- Agent evaluations were not run because they require separate explicit
approval
