+  `20260903-design-message-send-client-8d3f2a71` is integrated on `main` as

+  `20260903-design-message-send-client-integration-6f3a8c21`. Electron Main now
+  carries explicit outcome certainty through the local route, Host API, Renderer
+  API, store, and chat presentation: failed/cancelled Agent Runs settle as
+  definitive failures, while commands accepted before polling, auth, transport, or
+  canonical-refresh uncertainty retain the same pending operation ID. Definitive
+  failures preserve the user's draft, remove partial assistant streams, and show
+  fixed youth-readable Chinese copy instead of claiming the message was not sent;
+  unknown outcomes preserve the draft, identity, and partial stream without
+  silently creating a new mutation. Focused Design tests passed 61/61, typecheck,
+  scoped ESLint, production build, pressure 1/1, and AI Design Electron E2E 2/2
+  passed. The ordinary full suite passed 1,865 tests with 2 conditional skips and

+  file passed 5/5 immediately in isolation. No server contract, database,

+# Task: Integrate AI Design command outcome fix
+
+## Identity
+
+- Task ID: 20260903-design-message-send-client-integration-6f3a8c21
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: 4d8b19eeb5e70c97d40d2db68f37ee9f425b54f0
+- Owner: codex-root
+- Status: Ready for Integration
+
+## Scope
+
+- Integrate completed client source commit
+  `83f3f134a6779251aaa18f3290308cd9221b038f` from task
+  `20260903-design-message-send-client-8d3f2a71` onto the current `main`
+  frontier `4d8b19eeb5e70c97d40d2db68f37ee9f425b54f0`.
+- Verify the Main-to-Renderer command-outcome contract on the integrated tree,
+  record the source under the canonical integrated-state snapshot, and close the
+  source/integration task ownership lifecycle.
+- Do not modify Works Square server code, Plugin navigation behavior, packaging,
+  deployment, publication, or remote branches.
+
+## Intent And Constraints
+
+- Preserve ADR-007: definitive Agent-run failures settle the matching pending
+  operation, while accepted commands whose result is transport-unknown retain the
+  same stable operation identity. Neither case may be described as a generic
+  message-send failure.
+- Cherry-pick only the exact reviewed source commit. Its parent is
+  `e9875145b41a2cb1827de10d27a4fc6a352704ea`, which is the exact merge base with
+  current `main`; subsequent mainline product changes have no path overlap with
+  the source's Main/Renderer Design files or focused tests.
+- Preserve the unified Plugin workspace, Coding runtime/reconciliation fixes, and
+  every other current-main behavior. The source task has no promotion candidate
+  and does not change architecture direction or public server DTOs.
+- Preserve these three pre-existing foreign untracked task records byte-for-byte
+  and never stage them:
+  `.project-docs/30-worklog/tasks/20260901-package-122-c5e8.md`,
+  `.project-docs/30-worklog/tasks/20260901-package-123-d7f3.md`, and
+  `.project-docs/30-worklog/tasks/20260902-client-hang-diagnosis-a47c9e2b.md`.
+- Do not use a destructive reset, stash, clean, rebase, force-update, push,
+  package, deploy, publish, or call a paid Provider. One soft reset of this task's
+  newly created local commit was later separately authorized by the user; it kept
+  the index and worktree intact so the source task record could be registered before
+  recommitting the identical patch.
+
+## Concurrent Task Gate
+
+- Task `20260903-design-message-send-client-integration-6f3a8c21` exclusively owns
+  the root `main` worktree at base
+  `4d8b19eeb5e70c97d40d2db68f37ee9f425b54f0` and holds the Integration lock.
+- The previous root Integration task was already `ready_for_integration`; its
+  normal release was blocked only by the three adopted foreign records. After the
+  user explicitly authorized recovery, it was released with `--force`; no file was
+  modified or removed. This task then adopted the same exact foreign records.
+- Source task `20260903-design-message-send-client-8d3f2a71` is clean and
+  `ready_for_integration` in its isolated worktree. Its task record, outcome,
+  verification, and empty Promotion Candidates were read.
+- The only owner created after the immediately preceding all-peer root Integration
+  gate is `20260903-package-129-a6f2`; it is ready and explicitly owns no product
+  source change. Plugin implementation/acceptance sources are already represented
+  in current `main` and do not overlap this source.
+- Gate result: Passed.
+
+## Project Context Loaded
+
+- Read the active task, project positioning, success criteria, current state,
+  decision index, ADR-007, system overview, module map, data flow, business rules,
+  evidence index, reflection index, commitments, stale-items register, and the
+  source task record.
+- Current authority is one Main-owned Works Square V2 transport and one
+  server-owned Current Specification. Renderer drafts remain local until a
+  canonical success; transport ambiguity must retain the original operation ID.
+- `project-positioning.md` remains an unfilled repository template, while the
+  concrete product boundary is supplied by `AGENTS.md`, current state, ADRs,
+  architecture, business rules, and success criteria. This stale placeholder does
+  not conflict with the requested bounded integration.
+- No source promotion candidate, accepted-decision conflict, or active semantic
+  ownership conflict was found.
+- Planning Gate result: Passed. Integration plan: cherry-pick the exact source,
+  resolve only if a real conflict appears, run focused and repository-required
+  verification, update this record and `current-state.md`, commit documentation,
+  then complete and release both task contexts from clean worktrees.
+
+## Outcome
+
+- Released the stale completed root Integration owner only after the user
+  explicitly authorized the required force recovery; verified that the three
+  existing foreign untracked records remained present and unchanged, then acquired
+  this task's exclusive Integration lock.
+- Cherry-picked exact reviewed source
+  `83f3f134a6779251aaa18f3290308cd9221b038f` without conflict onto current `main`,
+  creating product commit `a16dfd0d6f48b99899ba84ac63bde4dcd661d067`.
+  No later Plugin, Coding, package, or project memory behavior was replaced.
+- The first automatic cherry-pick committed the source task record before it could
+  be registered as an unchanged foreign source, so the documentation drift gate
+  blocked. With explicit user approval, soft-reset only that new unpushed commit,
+  registered the staged source record through `--adopt-existing`, and recommitted
+  the identical source patch. No file content was discarded or rewritten.
+- The integrated client now distinguishes a definitive failed/cancelled Agent Run
+  from a command accepted before an uncertain poll/refresh result. Definitive
+  failures settle pending state and partial streams while preserving the draft;
+  unknown results preserve the original pending ID, draft, and stream. Youth-facing
+  copy no longer misreports either outcome as a generic send failure.
+- Recorded the exact source and integrated behavior in `current-state.md`. No
+  promotion candidate or accepted decision required modification; this implements
+  ADR-007's existing stable-operation and authority rules.
+- No Works Square server code, database/API DTO, Plugin navigation, package,
+  deployment, publication, push, or paid Provider call changed.
+
+## Verification
+
+- Source-path comparison between `83f3f134` and the integrated working tree showed
+  the source task's files are identical after the conflict-free cherry-pick.
+- Focused Vitest: 6 files / 61 tests passed.
+- `corepack pnpm run typecheck` passed.
+- ESLint over all changed TypeScript/TSX source and test files passed with no
+  output.
+- `corepack pnpm run build:vite` passed for Renderer, Electron Main, Preload, and
+  utility bundles; only existing Browserslist, mixed-import, and chunk-size warnings
+  were emitted.
+- `tests/e2e/image-workspace-v2.spec.ts` passed 2/2 against the production build.
+- Full ordinary Vitest executed 225 files: 224 files / 1,865 tests passed, 2 tests
+  skipped, and the unrelated Pi real-process Bash-batch test exceeded its existing
+  2,000 ms timing assertion at 2,433 ms while tests, typecheck, and ESLint competed
+  for resources. The exact real-process file immediately passed 5/5 in isolation;
+  its files and behavior are outside this integration diff.
+- The isolated pressure suite passed 1/1.
+- Independent source-task review had no remaining supported-path P1/P2 finding.
+
+## Follow-ups
+
+- None recorded.
+
+## Promotion Candidates
+
+- None recorded.

+# Adopt source task records before committing an Integration
+
+## Trigger
+
+Integration task `20260903-design-message-send-client-integration-6f3a8c21`
+cherry-picked a reviewed source commit with the default auto-commit behavior. The
+product patch was clean, but that commit also introduced the source task record.
+`check_doc_drift.py` correctly blocked because the Integration ownership record had
+not captured that foreign task-owned document as an unchanged source.
+
+## Recovery
+
+No product or user file was lost. After explicit user approval, the task soft-reset
+only its newly created, unpushed commit, preserving both index and worktree. It then
+resumed the same Integration ownership with `--adopt-existing` while the exact source
+record was staged, verified the staged patch, and recommitted the identical source
+change.
+
+## Reusable Rule
+
+When a source commit adds or updates its own task record, do not let cherry-pick
+auto-commit it inside an already-owned Integration worktree. Use
+`git cherry-pick --no-commit <source>` (or pause an ordinary merge before commit),
+then resume the same Integration task with `task_context.py start ...
+--adopt-existing`. Confirm the source record is byte-for-byte unchanged, commit the
+source patch, and run the task-aware drift check. Never edit the source task record
+to make the gate pass.
+
+## Evidence
+
+- Source: `83f3f134a6779251aaa18f3290308cd9221b038f`.
+- Integrated product commit:
+  `a16dfd0d6f48b99899ba84ac63bde4dcd661d067`.
+- The source-path comparison and final task-aware drift check verify that the
+  source record and product files were integrated unchanged.
