Oleg Isonen 6e10ae3809 fix: Fix Builder paste transfer data handling and publish sync edge cases (#5861)
- Fix publish sync for empty JSON data variables
- Retry transient asset downloads once with shared sync-client backoff
- Fix Builder paste handling for Webstudio transfer data
- Add transfer/data-envelope terminology and colocated runtime
data-format modules
- Rename page clipboard runtime operation to page transfer semantics
- Report malformed Webstudio/Webflow paste data through paste results
instead of inserting it as text
- Add browser-level E2E coverage for instance, page, folder, template,
generic plugin, malformed data, native input, and content-mode paste
flows

## Details

- Allows empty JSON data variables to sync/publish correctly.
- Adds asset download retry coverage and uses shared backoff logic.
- Introduces runtime `data-formats` modules for data envelopes, instance
transfer data, and page transfer data.
- Removes stale clipboard aliases and `validateTemplateStructure`.
- Keeps clipboard as a Builder UI transport concern while
runtime/protocol use transfer-data terminology.
- Changes paste plugins to return expressive success/error results so
callers can show toast errors and stop fallback insertion.
- Prevents malformed Webstudio transfer payloads from falling through to
text/HTML/markdown insertion.
- Handles malformed Webflow-owned paste data without throwing.
- Adds shared copy-paste fragment insertion helpers to reduce duplicated
breakpoint-warning/fragment-data logic.

Builder e2e

Fast local reruns

Use the full command for CI-like validation:

pnpm e2e:builder

For local test authoring, keep the e2e backend and Builder dev server running and rerun only the matching test. This avoids rebuilding Builder and avoids restarting Docker for every edit.

Terminal 1:

pnpm e2e:builder:dev:backend

Terminal 2:

pnpm dev

Terminal 3:

E2E_TEST_FILTER="Builder can copy, duplicate, and delete a page" pnpm e2e:builder:dev

E2E_TEST_FILTER is a substring match against the test name. It is not a regular expression. If the filter matches no tests, the runner fails and prints the available test names before starting Docker or building Builder.

Use E2E_TEST_FILTERS for a newline-separated list of exact or substring matches. Each entry is matched against both the test name and <suite> › <test>.

E2E_TEST_FILTERS='Builder can insert through the engine bridge
Builder-created data variables and resources persist' pnpm e2e:builder

CI shards the full e2e suite by file name tags such as pages-actions.[shard-3].e2e.ts. Use E2E_TEST_SHARD=shard-3 to run one shard. The goal is to keep all coverage while preventing one long serial e2e command from hitting the command timeout.

When adding a new e2e file, include one shard tag in the filename:

my-workflow.[shard-1].e2e.ts
my-workflow.[shard-2].e2e.ts
my-workflow.[shard-3].e2e.ts

If one workflow file grows too slow, split it by scenario into files with the same base name and different shard tags:

large-workflow.[shard-1].e2e.ts
large-workflow.[shard-2].e2e.ts
large-workflow.[shard-3].e2e.ts

Choose the shard by current CI timing, not by feature ownership. Put new or expensive files into the fastest shard, and rebalance later by renaming files. CI retries a failed shard once because a single shard rerun is cheap enough to absorb occasional browser/backend flakes.

pnpm e2e:builder:dev defaults to E2E_BUILDER_URL=https://127.0.0.1:3000, so it runs against the already-running Vite dev server instead of building and serving the production bundle. Override E2E_BUILDER_URL when the dev server is running on another port.

The dev backend uses E2E_DB_BOOTSTRAP=if-empty and keeps Docker containers running. The e2e runner still resets test data before each run.

When you need a clean backend:

E2E_SKIP_CLEANUP=false pnpm e2e:builder
