 ## Integrated Through
 
+- `6478591` / `3a6d388`: AI Canvas task-stream reconciliation now reuses an in-flight `connecting` Conversation stream instead of opening a duplicate; rapid Conversation-switching regression coverage is present. Canonical `main` promotion is pending release of the occupied main worktree, and real slow-handshake Electron smoke remains pending.
 - `ce897f1` / `6504073`: AI Programming now isolates prompt lifecycle, loading and errors by OpenCode Session. Main serializes only runtime/configuration acceptance, verifies project Agent content against an owned fresh runtime generation before execution, and returns typed terminal pending responses without automatically restarting, reloading or disposing the shared runtime. A run that receives no explicit busy/assistant/terminal acknowledgement within 10 seconds ends only that Session and is never replayed automatically. The application-side isolation is verified; real bundled OpenCode/provider two-Session execution concurrency is not claimed.
 - Project-cover source commit `145a6ce571d646325092d1e722282babea503954` from feature task `20260817-project-cover-upload-a6a98e56`, integrated by task `20260813-sync-push-main-9c2f71`. First submission now requires a bounded PNG/JPEG/WebP cover, shows preview/file/reselect feedback, and sends metadata plus cover through Main-owned `POST /api/projects/with-cover`; conflicts stop before version upload and existing draft/published projects remain version-only. The matching Works Square server source is `407c883` (local merge `0cedfc4`). No client package, production deployment, or real-account smoke occurred.
 - `3b37ac3` / `55e61b7`: macOS Robot hotspot discovery performs one bounded worker-thread rescan after an empty or SSID-redacted CoreWLAN result; persistent SSID redaction maps to the existing permission error instead of a misleading empty-device state, while firmware and the open `Xiaozhi-*` contract remain unchanged.

+# Task: Finalize AI design session freeze promotion
+
+## Identity
+
+- Task ID: 20260819-finalize-session-freeze-9d4a
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: 803e3d81739ae856d2a3a77496e4b71af8a06842
+- Owner: codex-root
+- Status: Ready for integration
+
+## Scope
+
+- Finalize the user-authorized promotion of the reviewed AI Design rapid Conversation-switching fix, already present at canonical `main` `803e3d8`.
+- Record the completed promotion and its canonical verification without changing product behavior or rewriting existing history.
+
+## Intent And Constraints
+
+- Operate in an exclusively owned Integration Gate worktree with the integration lock.
+- Keep the source feature task and prior integration task records read-only; this task records only the final promotion evidence.
+- Leave `main` clean and ahead of `origin/main` by the intended local integration commits; publishing remains a separate release action.
+
+## Outcome
+
+- `main` was fast-forwarded from `31332f6` to `803e3d8` after explicit user authorization to take over the clean worktree. No existing commit was reset, overwritten, or conflicted.
+
+## Verification
+
+- `check_project_docs.py --target .` passed before promotion.
+- `git merge-base --is-ancestor 31332f6 803e3d8` passed and `git merge --ff-only 803e3d8` completed successfully.
+- Canonical `main`: `tests/unit/image-workspace-store.test.ts` 31/31; `tests/unit/image-canvas-page.test.tsx` plus `tests/unit/works-square-design-workspace.test.ts` 79/79; scoped ESLint; TypeScript `--noEmit` all passed.
+- Existing React `act(...)` warnings appeared in the adjacent Canvas test and did not fail the suite.
+- Final task-aware documentation drift, `git diff --check`, and clean-worktree checks will run after this record is committed.
+
+## Follow-ups
+
+- Run the real logged-in Electron slow-handshake Conversation-switching smoke from the source task; local tests do not claim production gateway behavior.
+- Publish local `main` commits through the normal repository review/release process when desired.
+
+## Promotion Candidates
+
+- None. The reviewed fix is now present on canonical `main` and restores the existing stream-lifecycle invariant.

+# Task: Integrate AI design session freeze fix
+
+## Identity
+
+- Task ID: 20260819-integrate-session-freeze-7c4e
+- Mode: Integration
+- Branch: codex/20260819-integrate-session-freeze-7c4e-integrate-session-freeze
+- Worktree: D:\mk-merge-session-freeze-4c2e
+- Base commit: 31332f6d766bd3733e6fbb9c07688765368c2fa0
+- Owner: codex
+- Status: Ready for integration
+
+## Scope
+
+- Integrate the reviewed client fix from feature task `20260819-makelore-session-freeze-7c4e` (`3a6d388`) into the client `main` base `31332f6`.
+- Preserve the peer task `20260818-video-duration-server-config-7b4e` and its occupied canonical worktree; do not rewrite `main` or any unrelated source.
+
+## Intent And Constraints
+
+- Merge only the reviewed feature commit with a non-fast-forward integration commit; no reset, force update, stash, or destructive cleanup.
+- Keep the feature task record immutable and record integration evidence only in this integration task and the canonical `current-state.md`.
+- Leave the integration branch ready for promotion once the canonical `main` worktree is released by its owner.
+
+## Outcome
+
+- Created merge commit `6478591` (`merge: integrate AI design session freeze fix`) with no conflicts. The final integration snapshot keeps the `connecting`-stream reconciliation fix in `src/stores/image-workspace.ts` and its regression test in `tests/unit/image-workspace-store.test.ts`; the source task record remains owned by the feature branch and is not promoted into the canonical tree.
+
+## Verification
+
+- Source worktree verification recorded by the feature task passed: focused store tests 31/31, adjacent Canvas/workspace tests 78/78, scoped ESLint, TypeScript `--noEmit`, `git diff --check`, documentation drift, and independent Sol review PASS.
+- Integration worktree rerun passed: store tests 31/31, adjacent Canvas/workspace tests 79/79, scoped ESLint, TypeScript `--noEmit`, `check_project_docs.py`, task-aware `check_doc_drift.py`, and `git diff --check`. The adjacent test suite emitted only its pre-existing React `act(...)` warnings.
+
+## Follow-ups
+
+- Canonical client `main` remains owned by `20260818-video-duration-server-config-7b4e`; after that task releases the worktree, promote `6478591` to `main` and rerun the focused verification on the canonical checkout.
+- Perform a real Electron smoke with a deliberately slow event-stream handshake to cover the production timing boundary; this remains a follow-up from the feature task.
+
+## Promotion Candidates
+
+- `6478591` / `3a6d388`: update `current-state.md` under `Integrated Through` when the merge commit is promoted to canonical `main`.
