slate v2 integration failures

Objective: Fix every current full local integration failure in .tmp/slate-v2, using the async integration runner as the source of truth.

Goal plan: docs/plans/2026-05-27-slate-v2-integration-failures.md

Template: docs/plans/templates/task.md

Primary template: docs/plans/templates/task.md

Applied packs:

• browser (docs/plans/templates/packs/browser.md)

Task source:

• type: user request
• id / link: current Codex thread
• title: fix all current Slate v2 local integration failures
• acceptance criteria: fresh full bun test:integration-local:async run for the current source stamp reports failures: 0; focused repros for repaired specs pass; this plan passes check-complete.

Completion threshold:

• .tmp/slate-v2 has no current full local integration failures.
• Repaired rows have focused reproducer/proof commands recorded.
• Final full async run is fresh for the current source stamp and reports status: passed, failures: 0.
• Root autogoal checker passes for this plan.

Verification surface:

• .tmp/slate-v2: bun test:integration-local:async
• .tmp/slate-v2: bun test:integration-local:status <run-id>
• .tmp/slate-v2: focused Playwright/package/unit commands for repaired failure rows.
• Root: node .agents/rules/autogoal/scripts/check-complete.mjs docs/plans/2026-05-27-slate-v2-integration-failures.md

Constraints:

• Preserve existing user-facing behavior outside the integration failures.
• Prefer the durable ownership boundary over caller-by-caller patches.
• Do not create PRs, comments, commits, or pushes.
• Do not run root git hygiene.

Boundaries:

• Source of truth: latest full async integration run under .tmp/slate-v2/.tmp/integration-runs.
• Allowed edit scope: .tmp/slate-v2 source/tests/docs plus this root plan.
• Browser surface: Slate v2 Playwright integration examples served by the async runner.
• Tracker sync: N/A, no external issue/Linear ticket in this request.
• Non-goals: no PR, no root git hygiene, no release/registry/template work.

Blocked condition: Only blocked if the async integration runner cannot produce a failure list after repeated infrastructure-safe attempts, or if failures require unavailable external device/browser infrastructure. This did not occur.

Task state:

• task_type: browser regression repair
• task_complexity: normal
• current_phase: closeout
• current_phase_status: complete
• next_phase: final response
• goal_status: ready to complete

Current verdict:

• verdict: complete
• confidence: high
• next owner: user
• reason: full async integration run 2026-05-27T13-28-11-218Z passed with failureCount: 0 for source stamp sha256:e38bb0e85a62d712b14ca1abf80293d4c3f0852c892ede816b44727a0a0924cb.

Completion rule:

• update_goal(status: complete) is legal after this plan passes the checker.
• This file plus the active goal are the durable state.

Findings:

• Full run 2026-05-27T13-14-05-589Z failed in comment-mode, DOM coverage boundary drag, and table drag after earlier stale buckets were fixed.
• Root cause was over-broad projected drag handling: ordinary same-root drags were treated as projected selections and the native DOM selection was cleared.
• DOM coverage boundary pointer targets also needed direct boundary event-point resolution instead of relying on browser caret APIs for non-editable placeholders.

Decisions and tradeoffs:

• Keep native DOM selection/import for ordinary same-root text drags.
• Use model selection for same-root DOM coverage boundary drags.
• Keep view selection only for real cross-root or different-owner projected drags.
• Keep the async runner artifact-facing by building packages before the static site and keying source stamps on packages.

Implementation notes:

• .tmp/slate-v2/scripts/integration-local-async.mjs owns server lifecycle, skips occupied ports, includes packages in the source stamp, and builds package artifacts before bun build:next.
• .tmp/slate-v2/packages/slate-browser/src/playwright/index.ts uses semantic handles for selection/focus where DOM selection is not observable, including WebKit Shadow DOM.
• .tmp/slate-v2/packages/slate-react/src/editable/root-interaction-controller.ts restricts projected drag selection to cross-root/different-owner drags and DOM coverage boundary drags.
• .tmp/slate-v2/packages/slate-dom/src/plugin/dom-editor.ts resolves DOM coverage boundary event targets before generic DOM event range resolution.
• .tmp/slate-v2/packages/slate-react/src/components/editable-text-blocks.tsx marks content-root slots as non-editable islands.

Review fixes:

• Type-depth issue in the Playwright harness was fixed by using a small local synthetic-key type instead of KeyboardEventInit in locator serialization.

Error attempts:

Error / failed attempt	Count	Next different move	Resolution
Shadow DOM WebKit focus waited for unobservable DOM selection	1	Use semantic handle focus/press transport	Focused run 2026-05-27T13-13-17-201Z passed
Fresh full run exposed over-broad projected drag handling	1	Split native same-root, model boundary, and view-projected drag paths	Focused run 2026-05-27T13-27-17-666Z and full run 2026-05-27T13-28-11-218Z passed

• .tmp/slate-v2: full run 2026-05-27T13-28-11-218Z, source stamp sha256:e38bb0e85a62d712b14ca1abf80293d4c3f0852c892ede816b44727a0a0924cb, passed with failureCount: 0; failures artifact says No failures.

Final handoff contract:

• PR line: N/A, no PR requested.
• Issue / tracker line: N/A, no tracker requested.
• Confidence line: high; final full local integration sweep passed.
• Flow table:
  • Reproduced: full run 2026-05-27T13-14-05-589Z failed with 10 current failures.
  • Verified: full run 2026-05-27T13-28-11-218Z passed with 0 failures.
• Browser check: async Playwright integration runner covered the browser surface.
• Outcome: all current full local integration failures are fixed.
• Caveat: no PR/check/commit was requested.
• Design:
  • Chosen boundary: root interaction and DOM event-range ownership.
  • Why not quick patch: test assertions were valid; the runtime was stealing native same-root drags.
  • Why not broader change: cross-root view selection still needs the projected path and was preserved.
• Verified: focused repros plus final full async run.

Reboot status: The goal is ready for completion. The authoritative green run is .tmp/slate-v2/.tmp/integration-runs/2026-05-27T13-28-11-218Z, and the root autogoal checker passed for this plan.

Open risks: None known. The remaining risk is ordinary browser flake, covered by the final full run and focused repros.
