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 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 b832a8e808 refactor: Centralize Builder ID generation (#6323)
## Outcome

Builder-owned code now routes standard ID generation through
`@webstudio-is/sdk/createId` while preserving existing NanoID and UUID
formats.

Closes #6322

## Technical choices

- Use `createId("nano")` for Builder records, assets, transaction IDs,
and other existing NanoID-backed values.
- Use `createId()` for UUID-backed database records and browser-side
client IDs.
- Keep `BuilderRuntimeContext.createId` as an injectable dependency.
Runtime operations, copy/paste, and deterministic tests rely on that
injection.
- Keep Node's `randomUUID` in CLI paths that explicitly support running
without the Web Crypto global.
- Keep specialized generators for custom-alphabet project domains and
actual hash generation.
- Remove direct `nanoid` dependencies from packages where no specialized
use remains.
- Do not migrate existing data or change database schemas.

## Todo

- [x] Migrate Builder app ID creation.
- [x] Migrate project runtime and template defaults.
- [x] Migrate asset, project, domain, and authorization-token IDs.
- [x] Preserve runtime ID injection.
- [x] Review remaining direct generators as explicit exceptions.
- [x] Add NanoID-format regression coverage for the default runtime
context.
- [x] Review documentation impact: no user-facing documentation changes
are needed.
- [x] Review fixture impact: no fixture input or generated output format
changes are needed.
- [x] Run targeted tests, typechecks, lint, and package-boundary checks.

## Verification

- Targeted Builder tests: 153 passed after preserving runtime-context
injection.
- Project-build runtime tests: 270 passed.
- Asset uploader tests: 61 passed.
- Authorization-token tests: 17 passed.
- Project tests: 52 passed.
- Domain tests: 18 passed.
- CLI tests: 32 passed.
- Typechecks passed for Builder, project-build, asset-uploader,
authorization-token, project, and domain.
- `pnpm lint` passed.
- `pnpm check:package-boundaries` passed.
- The runtime-context format test was demonstrated to fail with a UUID
default and pass with the NanoID default.
- Agent evaluations were not run because they require separate explicit
approval.

Oleg Isonen c9618de88b fix: Scaffold projects with attribute aliases (#6300)
## Summary

- recover from every standard HTML/SVG and React attribute alias
collision during generated JSX export
- keep the last persisted value for non-class collisions, matching
existing duplicate-prop recovery
- merge distinct class aliases with generated atomic classes
- keep shared collision validation strict in authoring, import, MDX, and
instance-conversion paths

## Implementation

The React SDK generator now normalizes safe instance props before
generating JSX. One map keyed by the final JSX name provides
deterministic last-value recovery for exact duplicates and non-class
aliases. A second map keyed by the original class spelling preserves one
value per class alias so those composable values can be merged into the
single emitted `className` attribute.

Projected resource props use the same normalized-name set, avoiding a
second route to duplicate generated JSX properties.

## Checklist

- [x] Reproduce the reported `class`/`className` failure on unchanged
`main`
- [x] Reproduce non-class failures including `tabindex`/`tabIndex`,
`for`/`htmlFor`, and `readonly`/`readOnly`
- [x] Cover every current standard-to-React alias pair in both
persistence orders
- [x] Preserve exact duplicate-prop last-value behavior
- [x] Merge distinct class aliases with atomic classes
- [x] Keep strict shared validation outside generated JSX recovery
- [x] Review documentation impact; no user-facing documentation changes
are required
- [x] Review fixture impact; no fixture inputs or generated fixture
outputs are affected
- [x] Run targeted tests, typecheck, lint, build, and direct generator
reproducers
- [ ] Run `pnpm evaluations` if explicitly approved

## Verification

- `pnpm --filter @webstudio-is/react-sdk exec vitest run
src/component-generator.test.tsx --pool=forks` — 156 passed
- `pnpm --filter @webstudio-is/content-engine exec vitest run
src/jsx-attributes.test.ts --pool=forks` — 3 passed
- `pnpm --filter @webstudio-is/react-sdk typecheck`
- `pnpm --filter @webstudio-is/react-sdk build`
- `pnpm exec oxlint --deny-warnings
packages/react-sdk/src/component-generator.ts
packages/react-sdk/src/component-generator.test.tsx`
- direct generator reproducers now emit one normalized property for
`tabIndex`, `htmlFor`, and `readOnly`

The exhaustive regression test is derived from the shared attribute
mapping, currently covering 105 non-class pairs in both orders; the
separate class test covers exact duplicate recovery, distinct alias
merging, and atomic classes.

Agent evaluations were not run because they require explicit approval.

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.

- `projectContentStorageChanges`, `createContentStorageProjection`,
`createContentStorageSelectorProjection`,
`executeContentStorageMutation`, `executeContentStorageTextReplacement`,

- `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

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

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

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 130d371759 perf: Skip resources in statically hidden subtrees (#6233)
## Summary

- Skip read-time resources scoped to an instance with literal
`show=false` or any descendant of that instance.
- Use the same static reachability rule in the Builder client preloader
and CLI-generated published resource map.
- Keep dynamic `show` expressions on the existing loading path because
their result may depend on resource data.

## Data path and performance

In the Builder, the client-side resource request set now excludes
statically hidden subtrees before requests enter the preloader.

For generated sites, the CLI still scans project instances and props
during build, but removes statically hidden subtrees from the page build
data. Their read resources therefore never enter the generated
server-side resource map and no corresponding resource network request
runs during page rendering.

This removes request and server/network cost for literal-`false`
subtrees. It does not remove build-time project scanning, and resources
under dynamic conditions still load.

## Compatibility

- No project schema or persisted data changes.
- No migrations.
- Action-bound resources retain their existing explicit-trigger
behavior.
- Dynamic `show` expressions retain current behavior.

## Checklist

- [x] Add shared static-subtree reachability logic.
- [x] Apply it to Builder preview resource preloading.
- [x] Apply it to generated/published resource collection.
- [x] Add Builder and generated-output regressions for direct,
descendant, visible, and dynamic cases.
- [x] Demonstrate the new regressions fail against the previous behavior
and pass with the implementation.
- [x] Review authoritative `docs/` content; no documentation update is
required because the UI and authoring workflow are unchanged.
- [x] Review fixture inputs and outputs; no fixture contains this
resource/show combination, so fixture regeneration is not required.

## Verification

- `pnpm --filter @webstudio-is/sdk test`
- `pnpm --filter @webstudio-is/react-sdk test`
- `pnpm --filter @webstudio-is/builder exec vitest run
app/shared/nano-states/props.test.tsx`
- `pnpm --filter webstudio build:content-runtime`
- `pnpm --filter webstudio exec vitest run src/prebuild.test.ts`
- Typechecks for SDK, React SDK, Builder, and CLI
- Targeted `oxlint --deny-warnings`
- `git diff --check`

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

Closes #6232
2026-08-24 18:45:46 +02:00
Oleg Isonen a2e01a8ebe fix: Export configured Webhook Form methods (#6192)
## Summary

- Add an optional metadata contract for copying allowlisted resource
fields into generated component props.
- Pass action resources into page component generation.
- Configure Webhook Form's resource-bound `action` prop to generate the
form's `method` prop.
- Preserve explicitly authored props over generated resource props.
- Add generic generator, schema safety, rendered static-export
regression coverage, and updated generated fixture output.

## Root cause

Builder stores a Webhook Form's selected method on its action resource,
not as an ordinary instance prop. Component generation serialized the
resource-bound action identifier but had no generic contract for copying
safe resource fields into component props. The generated component
therefore received `action={"action"}` without the configured method,
and plain HTML rendering omitted the `method` attribute.

## Implementation

Resource prop metadata can now declare same-named fields using
`generatedProps`:

```ts
generatedProps: ["method"]
```

The component generator resolves those declarations generically; it
contains no Webhook Form component checks. The schema currently
allowlists only `method`, so resource URLs, headers, bodies, and other
potentially sensitive configuration cannot be generated as component
props. An explicit instance prop with the same name takes precedence.

Dynamic routed Webhook Forms retain their existing browser-to-server
POST behavior. This change preserves configured resource metadata in
generated component output and does not add static Webhook submission
support.

## Todo

- [x] Reproduce the missing method from an existing resource-bound
Webhook Form.
- [x] Demonstrate the generator regression test fails against the
previous output.
- [x] Define a typed, allowlisted generated-props contract for
resources.
- [x] Apply generated props generically without component-name checks.
- [x] Preserve explicit instance props.
- [x] Verify a real SSG prerender contains `method="post"`.
- [x] Verify unsafe resource fields such as `url` cannot be generated.
- [x] Give the build/prerender regression test the established 30-second
timeout.
- [x] Regenerate and verify the affected Webstudio Features fixture.
- [x] Run affected lint, typechecks, unit suites, builds, and CLI
prebuild tests.
- [x] Review documentation impact; no update is needed because
configuration and static-site support constraints are unchanged.

## Verification

- Regression test before implementation: failed because resource-bound
forms contained `action` but no generated `method`.
- `@webstudio-is/sdk`: 517 tests passed; focused schema test passed
after the rename.
- `@webstudio-is/sdk-components-react`: 126 passed, 1 skipped.
- `@webstudio-is/react-sdk`: 140 tests passed; focused generator test
passed after the rename.
- CLI prebuild: 59 tests passed; focused rendered static HTML test
passed in 2.7 seconds with a 30-second test timeout.
- Webstudio Features fixture: regeneration is idempotent; typecheck and
production build passed.
- Typechecks: SDK, SDK components, React SDK, and CLI.
- Targeted formatting and `oxlint --deny-warnings`.
- React SDK and CLI builds.
- `git diff --check origin/main...HEAD`.
- Agent evaluations were not run because approval was not requested.

Oleg Isonen d5b3f3ab80 fix: Improve MCP authoring reliability (#6056)
## Summary

This consolidates the reported MCP reliability fixes into one delivery.

- validate all inserted fragment expressions with the shared runtime
rules and reject text/expression children when component content models
require elements
- return an actionable error for unsupported existing-resource
references in JSX
- preserve siblings rendered before expression children
- accept unresolved CSS-variable shorthand expansion and eliminate
dynamic-alt/`htmlFor` audit false positives
- resolve exposed underscore MCP names during focused discovery
- omit unavailable stopped-preview fields and restart stale iterative
previews for external clients
- bound single and responsive screenshot capture, return
`SCREENSHOT_TIMEOUT`, and discard failed reusable browser sessions
- dispose previews when shared MCP runs fail or stdio clients
disconnect, including complete Windows process-tree cleanup
- resolve generated route templates from the CLI-managed preview
workspace during responsive verification
- retry a browser that exits during rendered-audit startup and report
sanitized exit diagnostics with a concrete browser-path recovery action
- materialize complete current session data before preview generation so
route order and project styles cannot collapse from missing lazy
namespaces
- always include CLI and Node.js version fields in generated issue
reports, with explicit legacy-client fallbacks
- document the updated preview and screenshot contracts and regenerate
the CLI manual

The current branch also retains the protections already present on
`main` for dry-run isolation, CSS rewrite truncation metadata,
stderr-only progress, shortcut argument forwarding, strict MCP schemas,
and refreshed conflict diagnostics.

## Technical choices

- MCP command orchestration stays in `mcp.ts`; preview port/retry
behavior lives with `mcp-preview`, and persisted checkpoint storage
lives in `mcp-checkpoint`. Each module owns its matching tests.
- Expression validation lives on the shared fragment input schema,
reuses `listFragmentExpressions`, and emits the same structured
validation issues as prop bindings, so JSX-derived and structured
fragments follow one contract across fragment, collection, and runtime
UI insertion.
- Element-child requirements come from component registry content models
during fragment insertion; no component names are hardcoded in the JSX
parser. `CollapsibleTrigger` metadata now matches its enforced `asChild`
implementation.
- Stopped preview status returns only `running: false`; unavailable
`url`, `pid`, and `mode` fields are optional and omitted from JSON.
- Explicit `preview.start` restarts a stale compatible iterative
preview; managed screenshots keep their optimized refresh path.
- Screenshot operations share one timeout utility. A single capture or
complete responsive batch is bounded after preview readiness;
lower-level CDP deadlines use the same stable error code.
- Failed managed captures close and forget their browser session. A
closed browser session cannot restart itself while cancellation is in
progress, which prevents orphaned Chromium processes.
- One ownership helper disposes one-shot and multi-project MCP hosts on
success or failure. Shared `mcp run` hosts dispose in one `finally`
boundary, long-running MCP hosts dispose on connection close, and
Windows uses `taskkill /T /F` instead of killing only the npm wrapper.
- Framework template readers receive the absolute template directory
captured from the build root, so later async work cannot redirect them
to the linked project's cwd. The same option drives cleanup for React
Router, Remix, and Vike.
- Browser startup gets one bounded retry before a rendered capture batch
fails. Persistent failures report only the exit code, signal, or spawn
error code plus the supported `WEBSTUDIO_BROWSER_PATH` recovery action;
local paths and raw browser output are not exposed.
- CLI and MCP preview share one session materializer that ensures the
canonical Builder namespace set before writing `.webstudio/data.json`.
Serialization rejects incomplete snapshots instead of converting missing
style/instance namespaces into valid-looking empty arrays, and preview
freshness records the post-materialization project version.
- The CLI injects its package version and `process.versions.node`; issue
formatting now keeps both fields visible even for legacy reports that
omit runtime metadata.

## Checklist

- [x] Add regression coverage for every changed behavior
- [x] Demonstrate new regression tests fail without the corresponding
fixes and pass with them
- [x] Run affected package test suites and typechecks
- [x] Run lint, package-boundary, and generated API checks
- [x] Review fixture impact — no fixture inputs or outputs are affected
- [x] Review documentation impact and update the authoritative MCP CLI
manual source/generated output
- [x] Run the complete local agent evaluation suite

## Verification

- `@webstudio-is/project-build`: 2,090 tests passed
- MCP asset query result modes are preserved across create, read, and
update serialization
- complete local agent evaluation suite: all 5 fixtures passed,
1,308,276 aggregate tokens
- `@webstudio-is/react-sdk`: 140 tests passed
- `@webstudio-is/template`: 43 tests passed
- `webstudio` CLI: 956 tests passed
- issue reporter: 5 targeted tests passed
- MCP host disposal regression was demonstrated failing without the
shared ownership boundary and passing with it
- relevant package typechecks passed
- `pnpm lint` passed
- `pnpm check:package-boundaries` passed
- `pnpm check:generated-api` passed
- generated-doc tests, typecheck, sync, and regeneration passed; the
aggregate clean-tree command reports the intentionally changed generated
CLI manual
- stalled single capture, stalled four-viewport capture, startup retry
across a four-viewport batch, sanitized browser-exit diagnostics,
complete preview materialization, post-refresh version tracking,
closed-session restart, Windows process-tree cleanup, and
preview-workspace regressions were demonstrated failing without their
fixes and passing with them

## Known limitations

- External `baseUrl` screenshots remain caller-owned and intentionally
do not regenerate, restart, or stop that external server.

Oleg Isonen efbc3098c4 feat: add queryable Assets resources (#5946)
Closes #5919
Ref #5920

## Outcome

Extend the existing Assets system resource with optional queries for
Markdown, JSON, and standard file metadata. Unconfigured Assets
resources retain the existing fetch-all behavior and activate none of
the content-query infrastructure.

Files are the authoring model. A standalone content engine converts an
immutable snapshot of only the files required by configured queries into
one bounded, deterministic runtime database. Builder preview, SSR, and
SSG use the same query semantics without requiring a database service
for a published site.

## Final architecture

```text
Markdown / JSON files
        │
        ▼
ContentSource adapter
(FS or Webstudio Assets)
        │ immutable snapshot
        ▼
ContentCompilationPlan
(union of configured query requirements)
        │
        ▼
ContentCompiler
(parse, normalize, discover fields, enforce budget)
        │
        ▼
ContentArtifact
(bounded, deterministic, immutable JSON)
        │
        ▼
ContentDatabase
(filter, OR groups, sort, paginate, project, read content)
        │
        ├── Builder preview
        ├── SSR runtime
        └── SSG build only
```

The authoring/storage layer owns mutable files. The content engine
consumes immutable snapshots and produces immutable, disposable
artifacts.


Query authoring is a separate OpenAPI-driven path:

```text
Assets REST OpenAPI operation
+ standard request JSON Schema
+ dynamic field paths
        │
        ▼
Generic OpenAPI adapter
        │ resolved schemas, controls, paths, and transport mapping
        ▼
Generic query-builder core and React renderer
        │ arbitrary provider-defined value
        ▼
Assets REST request adapter
        │
        ▼
{ query: value }
```

The selected standard OpenAPI operation is the only source of query UI
semantics. Request parameters and JSON Schema describe the editable
data; the generic renderer derives controls and owns layout.

### Activation and compilation

- The compiler does not index every asset. It combines all reachable
configured Assets-resource queries into one `ContentCompilationPlan`.
- Static constraints such as folder, path, and file type select
candidate files. Dynamic values such as a route-bound slug cannot reduce
the build-time candidate set.
- The plan contains the union of fields used by filtering, sorting,
routing, projection, excerpts, and requested full content.
- Documents shared by multiple resources are stored once in one
deployment-wide runtime database.
- Markdown/frontmatter, JSON properties, excerpts, and full bodies are
prepared only when required.
- No configured content query means no parsing, artifact, or shipped
runtime dependency. Fresh generated apps need no content-runtime
cleanup; incremental generation removes stale integration if a
previously configured query is deleted.

### Runtime database limit

- `CONTENT_DATABASE_MAX_BYTES` limits the complete serialized runtime
database, not source files, images, or unrelated assets.
- The default is `500 * 1024` bytes and is presented as 500 KiB.
- Counted data includes indexed metadata, frontmatter/JSON properties,
excerpts, the field catalog, serialization overhead, and full Markdown
bodies only when requested.
- Prepublish validation builds and serializes the exact database that
will be attached to the immutable build, so it knows the unbounded size,
bounded size, included documents, omitted documents, and affected
resources.
- Overflow never stores partial documents. Candidates are ordered by
`createdAt` descending, canonical path ascending, and stable document ID
ascending. Missing dates follow dated documents. A document that does
not fit is skipped while smaller later documents are still considered.
- Exceeding the limit warns but does not block publishing.
- Builder preview can report exact bounded versus unbounded results when
dynamic expressions have concrete preview values. Prepublish warnings
remain conservative for future route values.

### Snapshot consistency

The source contract guarantees a consistent compilation, while adapters
provide the mechanism:

- Webstudio Assets captures asset metadata and immutable content
references.
- Filesystem sources capture file identity and verify files did not
change before accepting the artifact.
- A changed source retries once, then fails clearly instead of producing
a mixed-revision database.
- This requires no universal snapshot service, source-tree copy, or new
versioned-asset infrastructure.

### Package ownership

- `@webstudio-is/content-engine`: runtime artifact schema, query
execution, field catalog, compact runtime statistics.
- `@webstudio-is/content-engine/compiler`: source snapshots, compilation
plans, Markdown/JSON parsing, deterministic compilation, byte
accounting, and compiler diagnostics. This entry exists to keep
Remark/YAML/future MDX dependencies out of runtime bundles.
- `@webstudio-is/query-builder`: resolves standard OpenAPI operation
schemas into an internal provider-neutral editor model, validation,
mutations, and source serialization. It owns no Assets,
provider-authored UI contract, or fixed REST-query semantics.
- `@webstudio-is/query-builder/react`: container-neutral schema renderer
whose layout is renderer policy. It remains separate from the content
engine.
- SDK: Webstudio Assets/Resource domain models and mapping Webstudio
expressions into generic content requirements.
- Protocol: external Assets REST/OpenAPI transport contracts.
- Asset uploader/repository: asset and folder mutations, generic
metadata, immutable byte references, and storage access. Its hosted
adapter supplies Webstudio Assets snapshots and parsed-metadata cache
persistence to the content engine; parsing, artifact creation, and query
semantics remain engine-owned.
- Builder and generated-app integrations decide when to compile, cache,
embed, load, or discard a database.

### Runtime lifecycle

- Builder caches immutable `ContentDatabase` instances by source
revision plus compilation-plan hash and coalesces concurrent
compilation. Matching operations reuse the same instance; field
discovery uses a dedicated minimal all-properties plan that excludes
excerpts and bodies.
- SSR attaches the validated bounded database to the build and includes
the small runtime only when required.
- SSG uses the database only while generating pages and omits it and the
runtime from final output unless a future runtime-query feature requires
them.
- Local development compiles from the filesystem and uses identical
query semantics.
- Published pages query their local artifact; they do not call Builder
REST endpoints.
- Published artifacts need no external index store, invalidation,
garbage collection, SaaS content proxy, new bucket, or new environment
variable.

## Implemented foundation

These existing parts remain useful and should be moved behind the final
ownership boundaries rather than reimplemented.

- [x] Upgrade the existing Assets system resource in place and preserve
unconfigured fetch-all behavior.
- [x] Implement typed filtering, nested boolean groups, deterministic
sorting, pagination, projections, dynamic values, and content hydration.
- [x] Add Markdown frontmatter, excerpt, JSON-property, and
field-catalog extraction.
- [x] Add reusable query-control implementations and a separately
imported React UI as a foundation for the final OpenAPI-driven contract.
- [x] Add Assets query authoring and dynamic field discovery as existing
behavior to migrate into the Assets OpenAPI operation.
- [x] Add synchronized visual and editable expression authoring.
- [x] Unify Assets REST operations under `/rest/assets/*`.
- [x] Define authenticated collection, item, content, upload, folder,
query, field-catalog, and OpenAPI operations.
- [x] Support Builder cookie authentication and public API token
authentication.
- [x] Add Builder preview, MCP/CLI operations, SSR execution, SSG path
generation, and conditional activation.
- [x] Add revision-keyed parsed metadata persistence for the hosted
Builder.
- [x] Add focused query, API, authorization, Builder, CLI, SSR, SSG,
migration, and fixture coverage.

## Remaining implementation plan

### 1. Establish the content engine

- [x] Rename the generic `@webstudio-is/asset-resource` implementation
to `@webstudio-is/content-engine`.
- [x] Move existing behavior instead of creating a parallel
implementation.
- [x] Keep the primary entry runtime-only and add only the compiler
entry needed for bundle separation.
- [x] Remove the old package after all consumers migrate.
- [x] Ensure the engine has no Builder, SDK, asset-uploader, PostgreSQL,
R2, or deployment-target dependency.

### 2. Define source snapshots and compilation plans

- [x] Introduce `ContentSource.openSnapshot()` and a revision-bearing
`ContentSourceSnapshot`.
- [x] Include canonical path, stable document ID, content type,
immutable content reference, size, and optional `createdAt`.
- [x] Implement Webstudio Assets and filesystem snapshot guarantees
using their adapter-specific mechanisms.
- [x] Introduce `ContentCompilationPlan` for the union of reachable
configured resource requirements.
- [x] Separate statically selectable candidates from dynamic runtime
predicates.
- [x] Add mutation-during-compilation tests for replacement, deletion,
folder movement, and filesystem changes.

### 3. Separate storage from content processing

- [x] Keep upload, replacement, folders, byte storage, revisions, and
generic metadata in the Assets repository/uploader.
- [x] Move parsing, excerpts, field discovery, query execution, and
artifact creation into the content engine.
- [x] Remove content-index coordination from asset mutation business
logic.
- [x] Preserve original source `createdAt` across content replacement
and expose it as optional queryable metadata.
- [x] Keep hosted parsed-document persistence behind the content
compiler's optional cache interface.

### 4. Build deterministic compilation

- [x] Move the existing Markdown, frontmatter, JSON, canonicalization,
hashing, document-building, and tests into the compiler.
- [x] Keep frontmatter behind a dedicated module and continue using the
existing Remark/Micromark pipeline.
- [x] Parse only candidate files and only the tiers required by the
compilation plan.
- [x] Deduplicate documents and fields required by multiple resources.
- [x] Define a versioned, deterministic `ContentArtifact` with integrity
information.
- [x] Keep verbose parse and omission diagnostics outside the runtime
artifact.
- [x] Reject incompatible artifact versions cleanly.

### 5. Enforce the deployment-wide database budget

- [x] Replace the old asset-index limit with
`CONTENT_DATABASE_MAX_BYTES`, defaulting to 500 KiB.
- [x] Have applications read configuration and pass the byte limit into
the compiler.
- [x] Measure the exact serialized database, including selected bodies
and overhead.
- [x] Implement deterministic skip-and-continue packing of complete
documents.
- [x] Return compiler diagnostics with unbounded/bounded bytes,
included/omitted counts, omitted identities, largest contributors, and
affected resources.
- [x] Expose only compact artifact statistics at runtime through
`ContentDatabase.getStats()`.
- [x] Add exact boundary, deterministic ordering, deduplication, and
oversized-document tests.

### 6. Finalize the runtime database

- [x] Define `ContentDatabase` over an immutable artifact.
- [x] Preserve filtering, nested AND/OR groups, sorting, offset/limit,
projection, field references, and content retrieval.
- [x] Expose `getFieldCatalog()` and compact `getStats()`.
- [x] Keep Markdown/YAML/compiler dependencies out of the runtime entry.
- [x] Add execution guards and maximum-size runtime benchmarks.

### 7. Make query authoring OpenAPI-driven

The selected standard OpenAPI operation is the complete query-authoring
contract. The query builder resolves parameters and request-body JSON
Schema, derives its internal editor model, and applies renderer-owned
layout policy. It must not embed or fetch a second capabilities/UI
language through `x-webstudio-query` or another side channel.

- [x] Remove `x-webstudio-query` and all vendor query-definition
metadata from the Assets OpenAPI operation.
- [x] Resolve local OpenAPI references and derive the editable request
value, defaults, validation, labels, choices, arrays, objects, and
unions solely from standard operation parameters and request-body JSON
Schema.
- [x] Represent dynamic Assets field paths with standard JSON Schema
vocabulary in the `queryAssets` request schema.
- [x] Keep the normalized editor representation internal to
query-builder; do not expose another provider-authored capabilities
contract.
- [x] Remove provider-controlled layout metadata such as `group`; make
compact scalar packing and all other layout renderer policy.
- [x] Keep Webstudio expression binding as a consumer/editor concern
layered over schema values, not part of the OpenAPI contract.
- [x] Preserve the existing Assets filter, sort, output selection,
full-content/range selection, limit/offset, editable source, and
configured-field behavior.
- [x] Keep the Assets resource adapter responsible for serializing the
edited query into its request body.
- [x] Remove the obsolete Assets query-capabilities endpoint, URL, and
UI-side capability parsing.
- [x] Add a non-Assets OpenAPI proof with differently named parameters
and no vendor metadata.
- [x] Verify the generic packages contain no Assets imports, fixed
Assets property contract, or provider-authored layout model.
- [x] Update focused core, React, SDK, protocol/OpenAPI, Builder, and
source round-trip tests.

### 8. Manage ContentDatabase lifecycle in Builder

- [x] Cache databases by source revision plus normalized
compilation-plan hash.
- [x] Coalesce concurrent compilation requests.
- [x] Reuse cached database instances across field discovery,
autocomplete, query preview, and response preview when their normalized
compilation plans match.
- [x] Replace it when source revision or query requirements change.
- [x] Preserve the optional revision-keyed hosted parsed-document cache
without making it a source of truth.
- [x] Show exact preview warnings when concrete values reveal missing
bounded results.

### 9. Materialize and verify immutable builds

- [x] Compile and serialize the exact deployment-wide database during
prepublish validation.
- [x] Attach that validated bounded database to the immutable build
without rebuilding it from later asset state.
- [x] Show non-blocking prepublish warnings with database bytes,
omissions, and potentially affected resources.
- [x] Avoid claiming exact future route matches when dynamic values are
unknown.
- [x] Include the database/runtime only when a reachable configured
query requires them.
- [x] Ensure detail resources requesting Markdown content include all
statically eligible bodies needed by dynamic routes.

### 10. Integrate all targets

- [x] SSR: load the build's bounded database and conditionally include
the small runtime.
- [x] SSG: query the same database during generation, then omit
database/runtime output when no runtime query is needed.
- [x] Local/CLI: compile from the filesystem source with the same
semantics.
- [x] Preserve overview pagination, alternative route fields,
draft-as-user-data behavior, and full article rendering.
- [x] Verify ordinary Assets and fresh query-free sites perform no
parser, artifact, content-runtime dependency install, or cleanup work.

### 11. Correct API and package ownership

- [x] Move external Assets REST/OpenAPI contracts to
`@webstudio-is/protocol`.
- [x] Keep Webstudio domain models and Assets system-resource
configuration in the SDK.
- [x] Keep both cookie and token authentication behavior on the unified
Assets REST surface.
- [x] Remove pass-through route wrappers/reexports that add no transport
behavior.
- [x] Keep published runtime queries local to the artifact rather than
routing them through Builder REST.

### 12. Remove superseded deployment infrastructure

- [x] Remove external deployment-index upload, fetch, invalidation,
cleanup, and garbage-collection code.
- [x] Remove the SaaS asset-origin adapter requirement; close
webstudio-is/webstudio-saas#652 as superseded because it has no
independent purpose.
- [x] Remove index-bucket compatibility configuration and avoid adding
Infisical variables.
- [x] Remove obsolete external-index paths, package dependencies,
routes, scripts, and tests.
- [x] Consolidate unreleased intermediate migrations where safe and
retain only schema required by the final hosted cache/API design.

### 13. Verification and release readiness

- [x] Move and preserve existing tests while changing ownership; add new
tests only for changed contracts and behavior.
- [x] Run content-engine compiler/runtime tests, query-builder tests,
SDK/protocol/API tests, Builder tests, CLI tests, and affected
typechecks.
- [x] Run formatting, generated-file idempotence, fixtures, clean
Supabase-compatible migrations, E2E shards, and complete agent
evaluations.
- [x] Verify SSR and SSG conditional inclusion and query-free generated
package manifests.
- [x] Run the five-article MCP blog workflow: authoring, field
discovery, overview, dynamic detail routes, full Markdown rendering,
publishing, and published-site verification.
- [x] Run a maximum-budget database test and a
mutation-during-compilation test.
- [x] Perform a final architecture, security, API compatibility,
migration, bundle, correctness, and DRY review.
- [x] Reconcile every checkbox and replace the verification section with
results from the final architecture before release.

## Future MDX work

MDX is intentionally separate from this release.

- The compiler contract should allow a future build-only MDX parser.
- MDX compilation must not enter the published runtime.
- Embedded JSX must use an explicit compiled representation rather than
runtime source evaluation.
- Webstudio components, tokens, styles, and component allowlists remain
Webstudio integration concerns.
- The future MDX work should reuse `ContentArtifact` and
`ContentDatabase` where practical.

## Superseded design

The following earlier design choices are no longer the target
architecture:

- GROQ or GraphQL as the Assets query language.
- One external or long-lived index object per resource/query.
- A deployment index fetched by the Worker from SaaS/CDN infrastructure.
- Lazy production reads of source Markdown bodies.
- A separate index bucket, asset origin, invalidation service, or
garbage collector.
- A 4 MiB published index limit.
- Rebuilding an old build's database from the current mutable asset set.
- Bundling query infrastructure into projects without a configured
content query.

## Verification baseline

The embedded runtime-database architecture previously passed the checks
below. The OpenAPI-driven query-authoring change additionally passed:

- Query-builder core: 4 files / 19 tests.
- Query-builder React: 1 file / 7 tests.
- SDK Assets source/config: 1 file / 7 tests.
- Protocol Assets OpenAPI: 1 file / 9 tests, including independent
OpenAPI validation.
- Builder Assets OpenAPI description: 1 file / 5 tests.
- Query-builder, React, SDK, protocol, and Builder typechecks.
- Package-boundary validation and formatting of every affected file.

Local verification baseline:

- Content engine: 15 files / 104 tests.
- Asset uploader: 24 files / 175 tests.
- Builder: 204 files / 2,423 tests.
- CLI: 54 files / 866 tests.
- Complete workspace typecheck, formatting, lint, package boundaries,
generated fixtures, and fixture builds.
- The complete migration history applied successfully to a fresh
Supabase-compatible database, including every migration after the
consolidated Assets migration.
- Builder production build and full local E2E suite passed.
- Complete agent evaluations passed: authenticated page (170,859 ms),
design input (207,101 ms), and font assets (67,050 ms).
- Final review additionally verified correct REST edit/view/build
permits, cookie and public-token read paths, immutable snapshot retries,
exact database budgeting, query-free dependency omission, and SSR/SSG
conditional runtime inclusion.

Final staging verification passed against the embedded runtime-database
architecture: MCP uploaded and updated five Markdown articles,
discovered dynamic frontmatter fields, previewed a five-item sorted
overview and one full-body slug query, updated both Assets resources,
found zero binding issues, rendered `/blog` and `/blog/dynamic-routes`
at HTTP 200, published build version 266, and verified both published
routes at HTTP 200 with the expected article metadata and Markdown body.
The workflow also found and fixed offset-form asset timestamps failing
canonical datetime validation and made MCP `preview.start({ port: 0 })`
correctly select an available local port.

## Release constraints

- No new SaaS content service, bucket, or environment variable.
- No published-site database dependency.
- No parser/compiler dependency in query-free sites or runtime-only
bundles.
- The validated content database is immutable build output.
- Publishing warnings do not block deployment.
- The selected standard OpenAPI operation and its request JSON Schema
are the only source of query UI semantics.

Oleg Isonen 54aa7be145 fix: Make MCP authoring reliable across assets, styles, and embeds (#5932)
Closes #5924
Closes #5925
Closes #5926
Closes #5927
Closes #5928
Closes #5929

## Outcome

Makes MCP and CLI authoring predictable across project-wide CSS
variables, font uploads, retried asset uploads, destructive asset
selection, design-token collisions, and SVG HtmlEmbed edits.

## Delivered

### Project-global CSS variables

- [x] `define-css-variable` writes to `ROOT_INSTANCE_ID` / `:root`
instead of the home-page Body.
- [x] Breakpoint and overwrite behavior is preserved, and compact
results identify the root scope.
- [x] Existing body-local declarations remain untouched.
- [x] Runtime and Builder integration tests cover root selection and
generated project behavior.

### Font metadata and upload overrides

- [x] Static fonts prefer authoritative `OS/2.usWeightClass`.
- [x] Fallback matching normalizes spaces, hyphens, and underscores and
checks specific aliases before shorter ones.
- [x] Explicit format and partial metadata overrides travel through
HTTP, filesystem, and S3 upload paths and are validated after merging
with detected metadata.
- [x] Regression tests cover ExtraBold, Extra-Bold, Semi Bold Italic,
Ultra Light, valid weight classes, invalid weight classes, partial
overrides, and invalid overrides.

### Idempotent asset uploads

- [x] API uploads compute a project-scoped SHA-256 content hash.
- [x] Sequential and concurrent duplicate uploads reuse the existing
asset and return `deduplicated: true`.
- [x] `force: true` bypasses deduplication for intentional duplicates.
- [x] A partial unique index enforces one non-null content hash per
uploader project.
- [x] Stale reservations are cleaned up and active concurrent uploads
are bounded by polling and an actionable retry error.
- [x] HTTP, protocol, uploader, and CLI tests cover hash reuse,
uniqueness races, force propagation, and result markers.

The migration does not backfill historical files. Existing assets begin
participating in deduplication when uploaded through the new path;
matching content keeps the existing asset's metadata rather than
silently rewriting it.

### Consistent asset inputs and permissions output

- [x] `delete-asset` exposes exact `assetIds` and explicit
`assetIdPrefixes`.
- [x] The legacy `assetIdsOrPrefixes` input remains accepted and is
marked deprecated.
- [x] Exact ids no longer accidentally select longer prefixed ids.
- [x] `webstudio permissions` prints a readable role/capability summary
by default while `--json` remains unchanged for machine callers.
- [x] Help and discovery describe JSON output as optional.
- [x] Runtime, CLI, metadata, and generated-contract tests cover
canonical and compatibility behavior.

### Deterministic fragment design tokens

- [x] Fragment insertion reconciles incoming tokens against project
tokens and earlier tokens in the same fragment.
- [x] Equal name/style tokens are reused instead of creating suffixed
twins.
- [x] Same-name/different-style fragments require an explicit `ours`,
`theirs`, or `merge` policy at the public runtime boundary.
- [x] Builder's established internal paste behavior retains its explicit
incoming-value default.
- [x] `create-design-token` accepts documented CSS strings through the
property-aware CSS parser as well as typed style values.
- [x] Tests cover same-fragment reuse/conflicts, persisted tokens,
explicit policies, and CSS string parsing.

### Editable SVG HtmlEmbed content

- [x] HtmlEmbed validation uses parse5 parser errors and source
structure instead of serialization-string equality.
- [x] Valid inline SVG is accepted without silently normalizing authored
markup.
- [x] Fragment insertion now uses the same validator as prop update and
text replacement paths.
- [x] Malformed markup is rejected before mutation.
- [x] Regression tests cover realistic SVG, parser failures, and
no-partial-mutation behavior.

## Verification

- [x] `pnpm checks`: all workspace tests, typechecks, lint, package
boundaries, generated API/docs checks, and fixtures passed on the final
committed tree.
- [x] `pnpm --filter webstudio test:release-smoke`: packaged install,
compact comparison, preview, agent workflow, stdio MCP, and structured
commands passed.
- [x] Prisma schema validation passed with test connection variables.
- [x] Two minimally prompted weak-model subagents independently
exercised the changed CLI/MCP discovery and focused workflows.
- [x] The subagent-found stale `permissions --help` requirement was
fixed, regression-tested, and retested.
- [x] Final diff and worktree are clean.

Oleg Isonen d186d24501 feat: Improve MCP project audits, visual verification, and dynamic content authoring (#5874)
This update helps AI agents understand, audit, and visually verify
Webstudio projects more reliably. It also adds clearer guidance for
expressions, Collections, screenshots, and responsive rendered audits.

### Audit complete projects

- Run one `audit` command across accessibility, SEO, security, assets,
styles, and performance.
- Audit the whole project or focus on a specific page, scope, or
severity.
- Receive stable findings with locations, explanations, and recommended
fixes.
- Continue large result sets through pagination without repeating
general guidance.

### Audit the rendered website

- Build and inspect the generated website, rather than relying only on
stored project data.
- Check every static page at representative mobile, tablet, and desktop
widths.
- Use one suitable viewport inside each configured breakpoint range.
- Reuse the same browser and resize pages between captures for
substantially faster audits.
- Process multiple pages concurrently while keeping resource use
bounded.
- Supply concrete examples for dynamic routes such as blog posts.
- Review and confirm unusually large screenshot plans before they run.

### Find visual and performance problems

Rendered audits can detect:

- Horizontal page overflow.
- Broken images.
- Images loaded eagerly below the fold.
- Images that are much larger than their rendered size.
- Render-blocking resources.
- Legacy font formats.
- Pages that fail to load or redirect somewhere unexpected.
- Pages captured before their layout becomes stable.

Detailed screenshots, measurements, failures, and timing evidence are
saved locally for further inspection.

### Capture generated pages directly

- Capture a project route with `webstudio screenshot --path /route`.
- Automatically generate and start a temporary production-style preview.
- Stop the temporary preview after the screenshot is captured.
- Return navigation, responsive layout, and page-size evidence with JSON
output.
- Allow external image domains needed by the generated preview.

### Reuse generated previews

- Cache generated preview builds when the project has not changed.
- Reuse preview dependencies across regenerations.
- Keep preview dependencies isolated from the user’s project
dependencies.
- Surface preview build and startup failures with useful diagnostic
output.
- Include local project assets in generated previews.

### Author Collections correctly

- Explain when Collection is required for arrays and objects.
- Guide agents to bind the complete iterable instead of one item or the
response wrapper.
- Explain how Collection repeats its children for every entry.
- Explain current-item and current-key scope.
- Preserve Webstudio’s generated Collection parameters.
- Guide agents to use stable values for repeated interactive components.

### Write expressions with fewer mistakes

- Add a dedicated `webstudio://project/expressions` reference.
- Document expression scope, supported syntax, and supported methods.
- Explain how resources, variables, Collections, actions, and `system`
values are accessed.
- Distinguish fixed values from runtime expressions.
- Provide valid examples for text, props, resource URLs, headers, query
parameters, and bodies.
- Warn agents that valid syntax does not guarantee that runtime data has
the expected shape.

### Improve agent discovery

- Make Collection and expression workflows discoverable through
`meta.guide`.
- Return Collection-specific instructions through `components.get`.
- Point relevant command schemas to the expression reference.
- Keep detailed guidance available without placing it in every tool
response.

### Improve audit reliability

- Report which rendered captures passed, found issues, failed, or were
skipped.
- Distinguish planning, preview, capture, and cleanup failures.
- Include actionable retry instructions with rendered failures.
- Preserve completed evidence when part of an audit fails.
- Detect stale or conflicting preview servers more clearly.
- Support cancellation and bounded capture timeouts.

### Improve packaged CLI verification

- Add a release-shaped CLI smoke test.
- Install the packed CLI in an isolated temporary project.
- Fail on peer-dependency warning floods.
- Verify preview, screenshots, MCP calls, rendered audits, and generated
assets.
- Confirm that generic React Router previews do not include Docker-only
image dependencies.
- Keep CLI and MCP stdout machine-readable while progress remains on
stderr.

## User Impact

Agents can now audit a real rendered Webstudio site, inspect responsive
behavior, find concrete visual and performance problems, and provide
evidence for their conclusions. They also receive much clearer
instructions when turning API data into repeated content or writing
dynamic expressions.

Oleg IsonenandClaude Fable 5 de23e2a888 chore: migrate toolchain to oxc (oxfmt, oxlint, rolldown-vite) and typeScript 7 (#5868)
## prettier -> oxfmt (0.58.0)

- .oxfmtrc.json generated with `oxfmt --migrate=prettier`: trailingComma
es5, printWidth 80 (oxfmt defaults to 100), sortPackageJson disabled,
.prettierignore patterns folded in (file deleted).
- ignorePatterns additionally exclude yml/yaml/toml/jsonc and
packages/cli/templates/** so oxfmt covers exactly the file set prettier
used to format (ts,tsx,js,json,css,md) and never touches user-facing
scaffolding artifacts.
- root `format` script, nano-staged pre-commit hook and the CI check
(`pnpm oxfmt --check`, replacing `prettier --cache --check` and its
actions/cache step — oxfmt checks the whole repo in ~0.7s) now run
oxfmt.
- every generator script that ran `prettier --write` on __generated__
output now runs `oxfmt` (css-data, icons, html-data, postgrest, sdk,
sdk-components-*, apps/builder tailwind preflight).
- the four scripts that used prettier's JS `format()` API write raw
source instead and their package.json scripts pipe the generated file
through the oxfmt CLI: project-build generate-docs +
generate-runtime-operation-contracts, cli generate-docs, apps/builder
generate-server-only-api-metadata. oxfmt rejects paths containing "..",
so cross-package generated files are formatted via a subshell cd into
the owning package.
- one-time reformat: oxfmt's canonical output differs from prettier on 8
repo source files (binary-operator continuation indent, import() call
wrapping, sub-pixel spacing of empty for-clauses); oxfmt honors existing
`// prettier-ignore` comments so intentional layouts are kept.
- prettier remains ONLY as a cli devDependency for the
prettier/standalone HTML normalizer inside html-to-jsx.test.ts, and
inside fixtures/ + packages/cli/templates/ (ships to scaffolded user
projects; out of scope here).
- editor config switched from esbenp.prettier-vscode to oxc.oxc-vscode
(devcontainer extension list, .vscode editor.defaultFormatter).

## oxlint 1.56 -> 1.73

- oxlint 1.73 rules-of-hooks special-cases hooks NAMED useEffectEvent:
their results may only be called from effects. Our
app/shared/hook-utils/effect-event.ts is a stable-callback helper
(useEvent pattern), intentionally called from event handlers and passed
as props. The rule is disabled via .oxlintrc.json overrides for the five
files doing this (product code untouched); note those files lose
hook-order linting entirely until the rule becomes configurable.

## TypeScript 5.8.2 -> 7.0.2 (native compiler)

- `tsc` is now the Go-based native binary; all `tsgo` script usages
(workspace packages and fixtures) renamed back to `tsc` and
@typescript/native-preview removed (the package is being phased out).
- fixes for TS7 changed defaults and stricter checks:
- `types` now defaults to [] -> base tsconfig sets "types": ["node"]
(restores the implicit-@types/node behavior of TS5).
- `rootDir` now defaults to ./ -> every tsconfig.dts.json sets
"rootDir": "./src" (TS5011 otherwise).
- import assertions removed -> cli/src/cli.ts uses `with { type: "json"
}` (TS2880).
- stricter isolatedDeclarations inference -> explicit annotations in
css-data bin/property-filter.ts (TS9010) and image image-dev.stories.tsx
(TS9013).
- declaration serialization limit -> project-build builder-runtime.ts
runtimeOperationContracts gets an explicit type (TS7056); the annotation
preserves the narrow RuntimeOperationId union.
- TS7 ships no stable programmatic API:
- react-sdk (component-generator tests drive the compiler API) aliases
its typescript devDependency to @typescript/typescript6@^6.0.2; its bin
is `tsc6`, so the package's typecheck still runs native TS7 tsc from the
workspace root.
- generate-arg-types keeps typescript 5.8.2 for react-docgen-typescript.
- fixtures/ and packages/cli/templates/ keep typescript 5.8.2
(user-facing); fixture scripts still work because plain `tsc` resolves
to their local dependency.

## vite -> rolldown-vite 7.3.1 (oxc bundler)

- global pnpm override `"vite": "npm:rolldown-vite@^7.3.1"`: the builder
app (remix v2 vite plugin works unmodified), every package vite build
and the storybook build now bundle on rolldown/oxc.
- vitest is scoped BACK to vanilla vite via `vitest>vite`,
`vite-node>vite` and `@vitest/mocker>vite` overrides because vitest
3.1's runner does not understand rolldown's SSR transform
(__vite_ssr_exportName__ ReferenceError in every suite).
- those overrides pin vite EXACTLY to 6.3.4: letting ^6.3.4 float to
6.4.3 breaks cli prebuild tests (dynamic import of a generated
app/routes/$.tsx fails to resolve under 6.4.3's loader).

## unrelated cleanup requested during review

- apps/builder commands.ts imports duplicate-tokens-group statically
instead of via dynamic import. The circular dependency the dynamic
import guarded against only exists through the command-panel barrel
(command-panel.tsx > groups/index.ts > commands-group.tsx >
commands.ts); importing the group module directly is cycle-free
(verified with madge), matching the neighboring wrap-group and
convert-group imports.

## verification

- pnpm lint, oxfmt --check: clean.
- pnpm -r typecheck (TS7 native) and pnpm dts: clean.
- pnpm -r test: all suites pass (builder 2093 tests, cli 630, react-sdk
45, project-build 11, ...).
- builder app build, full workspace build, cli build and storybook build
all succeed on rolldown-vite.

Oleg Isonen c585918459 fix: Fix text binding rendering for non-text values (#5808)
Closes https://github.com/webstudio-is/webstudio/issues/2966

## Description

Fixes visitor-facing crashes when a text binding resolves to a non-text
value, such as an object returned from a resource.

Generated expression children now render through `renderText`, which
preserves strings and numbers and renders other runtime values as empty
text. This prevents React SSR from throwing `Objects are not valid as a
React child` when resource data shape changes unexpectedly.

## Changes

- Added `renderText(value)` runtime helper.
- Wrapped generated expression children with `renderText(...)`.
- Updated generated page imports to include `renderText`.
- Added rendering tests for resource status/error fields and
object-shaped bindings.

## Tests

```bash
pnpm --filter @webstudio-is/react-sdk test -- context.test.tsx component-generator.test.tsx
pnpm --filter @webstudio-is/react-sdk typecheck
pnpm --filter ./packages/cli typecheck

Oleg Isonen 16fa5ab0e3 feat: Basic authentication (#5779)
Closes https://github.com/webstudio-is/webstudio/issues/3991


Adds HTTP Basic Authentication support for published pages and
project-level `.wsauth` rules.

This introduces a new `@webstudio-is/wsauth` package that owns the
generic authentication format logic: parsing, validation, serialization,
route matching, resource generation, and request authentication. The
current supported method is `basic`, with the package structured so
additional auth methods can be added later.

Builder changes include:
- Page Settings now has an `Authentication` section for per-page Basic
Auth credentials.
- Project Settings now has an `Authentication` section for editing
`.wsauth` route rules.
- Page Settings was split into section-specific files with focused
tests.
- Auth UI shows Pro badges/info tooltips but remains editable.
- Publishing to custom domains is blocked on plans without `allowAuth`
when either page auth or project auth is configured.
- ProBadge now renders as a real pricing link and uses improved text
alignment.

Build/publish changes include:
- CLI prebuild generates and merges `.wsauth` entries.
- Published app templates enforce auth for HTML/XML routes.
- Generated auth resources are shared between build output and runtime.

[{a: 1}] and also object like this {key: {a: 1}}.

What this means is that now you can just iterate over objects returned
from some api, you don't need arrays-only any more.

As an item, the value of each object key will be provied.

Bogdan Chadkin 3fa0715560 fix: improve SSG output (#5555)
Ref https://github.com/webstudio-is/webstudio/issues/5389

1. **Title and meta tags (specified in page settings) are no longer
removed when page is loaded.** For this I switched to the same
components we use in cloud template.

2. **Avoid duplicating custom code**. Both server and client rendered
the same custom code and react instead of hydrating just duplicates
them. To fix this I removed custom code from client side so all scripts
and styles are rendered only once.

3. **Removed origin from og:image url.** Turns out it is not necessary
to have full url for og:image to work, all services are capable to
resolve url. We can remove it at least for static websites.

4. **SSG rendered fake url (https://url) in ld-json** which can have
unexpected results in search engines. Removed it, google should be able
to provide necessary url by itself.

Bogdan Chadkin 4dfdf50380 feat: migrate forms components to html elements (#5230)
Ref https://github.com/webstudio-is/webstudio/issues/3632

This is big one. So I switched to html elements whole forms section in
components. Though here I introduced some deviation from specification

**Textarea**

Initial value is represented as text content
```html
<textarea>content</textarea>
````

Though it is trickier to manage text content as state and all frameworks
rely on value property of textarea dom interface.

**Select**

Similar story. There is no value attribute and state is represented by
selected boolean attribute on options

```html
<select>
  <option value="value1" selected></option>
  <option value="value2"></option>
</select>
```

We replace selected attribute on option with value attribute on selected
when paste.

So basically all form elements are using "value" and "checked"
attributes which can be easily mapped to html and all frameworks.

Bogdan Chadkin c14238ed5e experimental: override some tags with components (#5210)
Ref https://github.com/webstudio-is/webstudio/issues/3632

Remix client routing should still work even if we go full html. Here
added tag overrides to component generator so sdk could pass component
replacements for some tags like

- body -> Body
- a -> Link
- form -> RemixForm

See example here

Bogdan Chadkin 646c5b38e7 fix: normalize html attributes only when not defined by component (#5215)
Proper fix for https://github.com/webstudio-is/webstudio/pull/5211

Now props meta are available in component generator and can be used to
figure if prop is defined by component or comes from html attributes.
Added same logic in canvas and component generator.

Also got rid from no longer necessary registeredComponentPropsMetas
store since all props are described by component meta.

Jaya Krishna Namburu be6b5fa966 fix: og-image bug fix for local assets (#5184)
## Description

Currently when a project is exported using `cli` and the built using any
inbuilt templates. The `og:image` fails with local assets. As the cli is
not prefixing the `assetBaseUrl` to the image name. Which is failing to
load.

I am passing the `assetBaseUrl` to `ProjectSettingsMeta` inside the
`react-sdk`. And using it as prefix if defined.


## Steps for reproduction

- Create a project and add a page to it.
- Upload and use an image for the `SocialImage` section under Page
Settings.
- Deploy the site, and share it anywhere for the `og:image` to kick in
when shared.

Ref https://github.com/webstudio-is/webstudio/issues/3632

Here enabled converting class -> className for all components with tags.
Now it does not affect anything though later will unlock using html
attributes instead of component props.

Also got rid from huge map with react properties and replaced it with a
set of proper aliases.

Bogdan Chadkin 87312f8809 experimental: generate meta for html and aria attributes (#5149)
Here added lists of attributes from html and aria specifications for
future Element component.

Html provides an easy to navigate table with all types with relations to
specific tags and descriptions.

Aria list with types is extracted from aria-query library. Though
descriptions are parsed from specification. In the future we will use
more aria-query data to navigate specific roles.

All attributes types are tested with react types

You can see generated data in
- packages/html-data/src/__generated__/attributes.ts
- packages/html-data/src/__generated__/aria.ts

Succeeds https://github.com/webstudio-is/webstudio/pull/2341
