\nPlanning Horizon: the finite archive-pivot waves (Paper UI activation → easy local run → general quality → archive), then archival — _(historical: this was an open \"Next 8 to 12 weeks\" release horizon before the 2026-06-13 archive pivot)_\nCompanion Active Docs:\n- `docs/STATUS.md`\n- `docs/IMPLEMENTATION_MASTERPLAN.md`\n- `docs/TESTING_GUIDE.md`\n- `docs/MANUAL_TEST_CHECKLIST.md`\n- `docs/GOLDEN_PRINCIPLES.md`\n\n## Purpose\n\nThis is the active execution guide for sequencing past, current, and the finite archive-pivot waves (Paper UI activation → easy local run → general quality → archive) that remain before archival.\n`docs/STATUS.md` is authoritative for current shipped reality; this document tracks delivery history, planned work, roadmap sequencing, and strategic intentions.\nUpdate this file at the end of each meaningful delivery cycle or when new work is seeded.\n\n## Direction (2026-06-13, maintainer-decided): finish-for-personal-use → archive\n\n**Taskdeck will not be distributed.** The maintainer's decision is to finish it as a personal-use tool, then archive it as a completed project. This **supersedes** both the 2026-06-05 ship-first framing (v0.1.0 → … → v1.0.0 GA) and the 2026-03-29 platform-expansion \"four pillars\" framing. Goals, in order:\n\n1. **Finish + activate the Paper UI** as canonical (ADR-0038 ratified) — **DONE**: the default-theme flip to `paper` **shipped 2026-06-27** (`#1252`; `paperThemeStore` default `off`→`paper` + a `td.paper.mode.v2` storage migration). All prerequisites shipped first: the `#1161` File-away dismiss affordance (`#1219`) + the reachable in-app Appearance theme toggle / Legacy escape hatch (`#1221`, 2026-06-19), and the Paper-review de-stubs (`onPreviewDiff` `#1234` / `onDefer` + `onReportBadSuggestion` `#1245`, 2026-06-27). Legacy stays reachable behind the Appearance toggle. Remaining Paper work is polish (Wave 4), not activation.\n2. **Trivially easy to run** locally — one-command dev-up plus a self-contained exe as the canonical personal run path.\n3. **General quality** — backend correctness + usability, proactively found.\n4. **Archive cleanly** — docs reflect the final state; de-scoped trackers closed with dated pivot notes.\n\n**De-scoped permanently** (closed as not-planned or parked during archive closeout, with dated notes): distribution & code-signing (`#1167`), GTM/marketing (`#544`/`#546`/`#550`), cloud & collaboration (`#537`/`#548`), mobile (`#540`), beta intake, multi-DB *production* support (the production runtime is SQLite-only forever; the PostgreSQL Testcontainers compatibility lane in CI — `Taskdeck.Integration.Tests` / `reusable-container-integration.yml` — remains as a legacy regression guard, not a product direction), and multi-user scale work. The platform-expansion strategy docs under `docs/strategy/` and the cloud/platform ADRs **0014, 0020, 0023, 0026–0028** are retained as historical records of parked tracks, not active plans. Three ADRs in the 0023–0029 range decide behaviour that is **still live** in the single-instance app — only their multi-instance/enterprise premise is parked: **ADR-0024** (the `ICacheService` cache-aside abstraction, in-memory by default), **ADR-0025** (the `AddTaskdeckSignalR` Redis-backplane wiring, config-gated and dormant in the single-instance default), and **ADR-0029** (optional TOTP MFA + OIDC/OAuth). Likewise the single-self-contained-executable packaging path in `docs/strategy/02_PACKAGING_DISTRIBUTION_STRATEGY.md` stays the active personal run path; only its installer / cross-platform-distribution / GTM framing is parked. **ADR-0004** (shared-schema multi-tenancy) also stays **live** for its cross-user-isolation behaviour — enforced today by per-`UserId` and board-access predicates rather than a `TenantId` column (no `TenantId` symbol exists in `backend/src`, `backend/tests`, or the frontend), with the `403`/`404` existence policy enforced in the running app (consistent with GP-02 Claims-First Identity and GP-03 Stable Error Contracts); only its multi-organization / hosted-SaaS expansion premise (including any `TenantId`-keyed shared-schema tenancy) is parked — agents must neither park the live cross-user isolation security model nor resurrect multi-org tenancy work. The planning principles below remain valid for the *product* (review-first, capture-friction, novice legibility) even though the *distribution* roadmap is retired.\n\n## Planning Principles\n\n> **Precedence note (2026-06-13):** The ordered goals in the **Direction** section above take precedence wherever these principles conflict. In particular, \"Security and identity convergence remains the highest-priority engineering track\" and the \"package the shipped substrate into stakeholder-legible business workflows\" / \"ship to first users\" framing reflect the pre-pivot product phase and are **historical** — the active priorities are now Paper-canonical, easy local run, general quality, then archive. The review-first / capture-friction / novice-legibility principles remain valid.\n\n- `docs/STATUS.md` is authoritative for current shipped reality.\n- Product north star: make capture nearly free and keep automation safe through review-first proposals.\n- Roadmap v4 north star: every automation-originated board write routes through proposals and human approval; manual board UI edits remain direct and auditable, not proposal-queued.\n- Mutation safety and exfiltration safety are distinct. Proposal-only writes do not protect local-first privacy; outbound data must be governed by EgressEnvelope, disclosure registry, MCP tool hash-pinning, and telemetry guardrails.\n- Product legibility is now the immediate product focus: the app should explain its core loop from inside the UI, not mainly through docs and demo scripts.\n- For near-horizon demo work, prefer packaging the shipped capture/review/board substrate into stakeholder-legible business workflows instead of reopening broad architecture.\n- Prefer finishing cross-cutting consistency work before adding new surface area.\n- Security and identity convergence remains the highest-priority engineering track.\n- Cross-user existence policy is fixed: return `403` for authenticated-but-unauthorized access and `404` for true missing resources.\n- Automation remains proposal-first and review-first by default.\n- Do not claim or ship silent/destructive autonomy by default; trust posture takes precedence over convenience.\n- MVP should include a dogfooding workflow: paste structured plan text in chat and bootstrap a board/project from approved proposals.\n- UX investments should be modular and reusable (keyboard-first, discoverable selectors, shared input-assist patterns).\n- Use `docs/InReview/MVP_EXPANSION/MINIMAL/` as the near-horizon execution filter and `docs/InReview/MVP_EXPANSION/EXPANDED/` as the staged roadmap reference.\n- Do not add major new surface breadth ahead of `Home` / `Today` / `Review` productization unless the work closes a real trust, safety, or operability gap.\n- Agent, knowledge, and integrations expansion stay sequenced behind novice-first productization even though their longer-term architecture is now clearer.\n- Every issue must carry exactly one priority label (`Priority I` through `Priority V`).\n- Out-of-code and configuration work (containerization, deployment, security posture, observability, DR) must be tracked as first-class backlog items.\n\n## Current Cycle Outcome (Completed)\n\nDelivered in the latest cycle:\n\nSecurity + a11y quality slices (2026-07-02, **2 PRs merged** — `#1263` (`#1241`), `#1265` (`#1218`); full review gate per PR — independent adversarial reviews, all-severity findings fixed or tracked, Gemini/Copilot bot rounds resolved (+Codex rounds on `#1263`), fresh green CI + aging):\n- **Windows secrets-at-rest ACL:** `#1263` (`#1241`) locks `appsettings.local.json` (JWT secret + connector encryption key) to the current user — `RestrictFileToCurrentUser` (Unix `0600` / Windows protected owner-only DACL, dependency-free on net8.0) runs create→restrict→write in `PersistValue`, fail-closed (an unrestrictable file is never written; callers fall back in-memory), with startup forward remediation for pre-`#1241` installs and a locked-down `.corrupt-*` backup. Review rounds also hardened the **MCP launch paths**: both MCP modes now load the local config via the same hardened path as the web API (absolute exe-adjacent path — MCP clients launch stdio servers from arbitrary CWDs; corrupt-file quarantine; env-vars keep priority over the file). Seeded: `#1262` (CLI bootstrapper sibling), `#1264` (atomic create-with-ACL — in flight as `#1267`).\n- **WCAG focus-ring contrast sweep:** `#1265` (`#1218`) resolves all 19 remaining `ring-primary/50` sites (0 left repo-wide): 13 rendered focus rings + the selected-label state ring lifted to the full-opacity treatment (`#1216` precedent) — from a marginal 3.0–3.5:1 to 8.4–10.1:1 on every adjacent surface across all shipped themes — and 5 compile-proven dead checkbox `focus:ring-primary` classes removed (no ring-width utility, so they never painted; the global `*:focus-visible` rule already covers those checkboxes at 4.52:1). Seeded: `#1266` (pre-existing white ring-offset halo on the selected-label state).\n\nWave-3 default-theme flip — Paper is now the DEFAULT UI (2026-06-27, `#1252`): `paperThemeStore` default `'off'`→`'paper'` (Paper canonical per ADR-0038), with the storage key bumped to `td.paper.mode.v2` and a one-time migration (a deliberate pre-flip `paper`/`paper-night`/`auto` choice carries over and the legacy key is cleared; a stored `'off'` — the old default / never-opted-in — or absent/invalid resolves to the new `'paper'` default). Legacy stays reachable through the Appearance toggle and is pinned in the test suites: the E2E `authSession` helper and a global vitest `setup.ts` hook both pin `td.paper.mode.v2='off'` so the ~19 legacy `.td-*` E2E specs and the Legacy-DOM unit specs keep asserting Legacy, while Paper-variant specs opt in explicitly. Review: a 2-lens adversarial sweep (0 confirmed) + Gemini round (migration inlined into `readStoredMode`); CI caught a 112-spec blast radius (the view shells render Paper by default) → fixed with the global off-pin; full FE suite green (3,752 tests).\n\nPaper-review de-stubs — Wave-2 completion (2026-06-27, 1 PR; built design-first): the last two stubbed Paper deep-Review handlers were wired to net-new backend, **unblocking the Wave-3 default-theme flip** (now shipped, above):\n- **`onDefer` → snooze 1h (ADR-0042):** a nullable `DeferredUntil` timing field + `Defer(TimeSpan)` domain method (the proposal stays `PendingReview`) and `POST /api/automation/proposals/{id}/defer` (default 60min, optional override clamped to [1,1440]). The snooze pushes `ExpiresAt` beyond the window so a deferred proposal never silently expires; the queue read path hides it (status-gated) while the live clock + backend filter resurface it; `DeferredUntil` is cleared on every terminal transition. No notification, no outcome (defer is not a decision). Re-snooze is unbounded but non-silent (toast + DTO field).\n- **`onReportBadSuggestion` → quality feedback (ADR-0043):** a new **content-free** `ProposalFeedback` table (reason-category enum, **no free-text field**) + `POST /api/automation/proposals/{id}/feedback` → 204, idempotent via a UNIQUE `(ProposalId, ReportedByUserId)` index (last-specific-wins on reason). Orthogonal telemetry — reporting **never** changes proposal status; read-access so a read-only reviewer can still flag; the substrate for a future cohort `reported_bad_rate` metric (`#1142`).\n- A parallel design + adversarial-critique pass pre-fixed the subtle edges before code: clearing `DeferredUntil` on decide so a decided proposal can't vanish from list reads; a 409 (not 500) on concurrent decide+defer via the existing `UnitOfWork` concurrency-token mapping; `Enum.IsDefined` so a junk/numeric `reason` is 400 not 500; correct two-migration lineage off `AddMcpToolHashes`. Coverage: +15 backend tests (domain/application/api, incl. idempotency, last-specific-wins, content-free reflection, 403/404/400/401) + rewritten Paper-review vitest (records / error / in-flight-guard / stays-in-queue).\n\nWave-6 backend + run-story delivery (2026-06-26, **3 PRs merged** — `#1236` (`#1195`), `#1238` (`#1193`), `#1240` (`#1131`); full review gate per PR — independent adversarial reviews, all-severity findings fixed, Codex bot threads resolved, fresh green CI + aging):\n- **Backend query bounds (Wave 6):** `#1236` (`#1195`) bounded the `LlmQueueToProposalWorker` status reads with type-aware in-query reads (`GetOldestPendingNonCaptureAsync` / `GetOldestProcessingCaptureAsync` + count methods for true telemetry) after review caught a HIGH starvation regression in the naive generic-limit design; `#1238` (`#1193`) paged `CaptureService.ListAsync` via a capture-only `GetCapturesByUserAsync(limit, offset)` with an OFFSET-boundary dedup guard. Both keep the unbounded `GetByUserAsync` for GDPR delete/export. Seeded `#1237` (remaining unbounded Pending reads) and `#1239` (push capture filters into SQL).\n- **Run-story (Wave 5):** `#1240` (`#1131`) makes the self-contained desktop exe runnable with no manual key — `ShouldAutoGenerateConnectorKey(isProd, isHeadless) => !isProd || !isHeadless` auto-generates + persists the connector key for the desktop (Production, not headless) while headless Production (CI / container / Terraform, via `TASKDECK_HEADLESS=true` in `backend.Dockerfile`) still hard-fails without a supplied stable key. The AWS Terraform `user_data` generates+persists the key on the durable data volume (with an existing-DB upgrade guard), and `backup.sh`/`restore.sh`/`restore.ps1` keep it paired with the database. A deep review loop (1 HIGH + many P2 across 6 Codex rounds + a 2-lens adversarial sweep) hardened the persistence path against silent key loss: reuse a masked persisted key instead of overwriting it, self-heal a corrupt local config, case-insensitive + provider-lenient reads, read-vs-parse error separation, and owner-only ACL on the restored key. **ADR-0041** records the decision.\n- **ADR added:** `ADR-0041` (desktop connector-key auto-generation; headless Production excluded).\n\nWave-6 follow-through (2026-06-30, **2 PRs merged** — `#1254` (`#1239`), `#1256` (`#1209`); full review gate per PR — 2 independent adversarial reviews, all-severity findings fixed, Gemini/Codex bot rounds resolved, fresh green CI + aging):\n- **Capture board pre-filter pushed into SQL:** `#1254` (partially resolves `#1239`) gives `GetCapturesByUserAsync` an optional `boardId` that applies `(BoardId IS NULL OR BoardId = @boardId)` in-query (SQLite raw + EF), so a board-filtered capture scan no longer materializes other boards' captures; null-board rows are retained because applied-conversion provenance (resolved in the service) can still map them to the target board, and the effective-board + status filters stay in the service. A behavior-preserving optimization (the SQL pre-filter is an exact superset of the removed in-service raw-board check). The status filter is provenance-derived and is not pushable to SQL, so `#1239` stays open for that part.\n- **Stuck-Processing recovery for non-capture requests:** `#1256` (`#1209`) adds a recovery sweep to `LlmQueueToProposalWorker` (mirroring `OutboundWebhookDeliveryWorker`) that reclaims non-capture `LlmRequest`s a crashed worker left in `Processing` past the lease (`Math.Max(30, Workers:ProcessingLeaseSeconds)`): each is returned to `Pending` while retry budget remains or `Failed` when exhausted, and — if the crashed attempt already committed its proposal — `Completed` regardless of budget. The non-capture drain (`ProcessSingleItemAsync`) also gained an existing-proposal idempotency guard (parity with the capture path), so neither recovery nor in-band retry can produce duplicate queue proposals. Two Codex rounds hardened the duplicate-proposal handling.\n\nArchive-pivot delivery wave (2026-06-13, **17 PRs merged** across Waves 0–2 — **Wave 2 nearly finished** after the **+4 follow-on PRs merged 2026-06-19** (`#1219`/`#1220`/`#1221`/`#1225`; **21 total**), including 2 dependabot bumps; full review gate per PR — 2 independent adversarial reviews, all-severity findings fixed, bot threads resolved, fresh green CI + aging). This wave completed Waves 0–1 of the archive-pivot plan and the bulk of Wave 2 (clear the PR deck → ratify Paper-canonical + cheap foundations → Paper-activation prerequisites + backend quality); the one remaining Wave-2 straggler is the Paper-review de-stubs (see **Net** below):\n- **Decision/foundation:** **ADR-0038** ratifies Paper as the canonical UI with Legacy frozen (`#1207`); **ADR-0039** moves the backend to Central Package Management with a pinned SDK and 8.x dependency alignment (`#1196`, carrying the `#1203` NuGet bumps into `Directory.Packages.props`); **ADR-0040** adds a global UTC DateTime materialization convention for SQLite (`#1201`). `*.migrate.lock` is now gitignored (`#1204`); the docker-compose quickstart documents both required secrets (`#1205`, `#1139` AC1).\n- **Paper activation prerequisites:** the shared review-actionability composable (`#1217`) extracts `isProposalApply/Reject/Approve/Dismissable` + `isProposalStale` as pure functions so Paper and Legacy can no longer drift at the 24h-stale / Approved+expired boundaries (collapsing the `#1124` double-fix), and removes fabricated author metadata in favour of the real `/confidence` value; paper-night straggler tokens + a full-opacity WCAG focus ring landed (`#1216`, `#1135`; seeded `#1218`). The `#1161` \"File away\" dismiss affordance that builds on this foundation **shipped 2026-06-19** (`#1219`), as did the reachable in-app Appearance theme toggle (`#1221`, `AppearanceSettingsView`).\n- **Backend + run-story quality:** dead `ProposalGeneratorV1`/`IProposalGenerator` removed as never-consumed code (`#1198`/`#1214`; `FieldVerifier`/`DeterministicPreExtractor` then removed too — `#1215`, 2026-07-04 — once the archive pivot cancelled the V2 generator that would have consumed them); Redis distributed-lock starvation fixed (`#1213`, `#1189`); the queue-claim raw-SQL path now reloads so the DTO isn't a stale identity-map entity (`#1200`, seeded `#1209`); automation-chat composable continuation guarded against dispose (`#1199`); the false-green E2E specs were re-enabled on real Paper selectors (`#1197`); and the one-command `dev-up` + `clean-workspace` scripts shipped (`#1208`, `#1140`) — the canonical personal run path's biggest ergonomics gap.\n- **Dependency hygiene:** group npm/nuget bumps (`#1202`/`#1203` in-wave, `#1211`/`#1212` follow-on).\n- **Net:** Wave 0 (clear the PR deck) and Wave 1 (Paper-canonical decision + cheap foundations) are complete, and Wave 2 (Paper-activation prerequisites) is now **complete** — the shared review-actionability foundation, the `#1161` File-away dismiss affordance (`#1219`), and the reachable in-app Appearance theme toggle (`#1221`) **shipped 2026-06-19**, and the final Wave-2 straggler — the **Paper-review de-stubs** (`onPreviewDiff` `#1234`, plus `onDefer` + `onReportBadSuggestion` on 2026-06-27, ADR-0042/ADR-0043) — landed, clearing the last blocker, and the **Wave-3 default-theme flip then shipped 2026-06-27 (`#1252`)** — **Paper is now the default UI.** Paper polish (Wave 4) and the independent run-story (Wave 5) and backend-quality (Wave 6) tracks interleave in the meantime. _(Also merged 2026-06-19: `#1220` canonical-docs reconciliation, `#1225` Redis major-version caps.)_\n\nSecurity gate + hardening epic (2026-06-05/06, 5 PRs merged; 2 independent adversarial reviews per PR plus Gemini/Codex bot reviews, all findings of every severity fixed or tracked):\n- **#1132 security gate + config hardening** delivered across 4 PRs: ≥32 JWT secret floor + fail-fast registration + Production CORS fail-closed (`#1169`, AC2/AC3); secret/dependency/SAST scans + bundle-size promoted into the required PR merge gate with **phased enforcement** per **ADR-0035** (`#1170`, AC1/AC5, fixed the pre-existing Semgrep `setuptools-82` crash); global default-deny `FallbackPolicy` + `[AllowAnonymous]` audit per **ADR-0036** (`#1176`, AC4).\n- **#1133 backend query perf** first slices (`#1171`): NotificationRepository SQL paging + CardRepository `AsSplitQuery`.\n- **#1131 AC1 CLI hardening** (`#1177`): fresh-machine connector-key bootstrap (CSPRNG, atomic write, `0600`, guarded mutex).\n- New ADRs `0035`/`0036`; seeded follow-ups `#1172`–`#1175`, `#1178`. Remaining: branch-protection registration (`#1173`), flip dependency/SAST to enforcing after baseline remediation (`#1175`), CLI authz routing (`#1131` AC2).\n\nCleanup/hardening wave (2026-05-31, 8 PRs merged, 2 issues closed; 2 adversarial review passes per PR, all findings of every severity fixed, all bot threads resolved):\n- **Open-PR backlog cleared** (`#1143`–`#1147`): non-watch `vitest run` + MetricsView flake (`#1143`); docs-truth corrections incl. ADR-0023→0025 + `.gemini` link-depth fixes (`#1144`); release scripts aligned to CI flags + stale PKG-01 warning removed (`#1145`); duplicate operation idempotency-key → **409 not 500** (`#1146`); `AsSplitQuery` on the multi-collection board read (`#1147`).\n- **Proposal-create hardening** (`#1125`/`#1151`): `ProposalOperationInputValidator` rejects malformed operation input (non-identifier `actionType`/`targetType`, non-JSON / >64 KiB / >depth-32 `parameters`) with **400** at the shared `CreateProposalAsync` path — a permissive format check (not a membership allowlist) so no legitimate producer is rejected. Adversarial review found and fixed a self-introduced HIGH (null `operations` element → 500).\n- **Roadmap-invariant enforcement** (`#1126`/`#1153`): INV-10/11/12 un-skipped with real assertions against `McpToolDefinitionHashService` / `TelemetryGuard` / `SourceSpan`+`ProposalProvenance` (Architecture.Tests now references Domain+Application); only INV-09 (DataFlowRegistry) stays skipped. Found the MCP hash service is registered but un-wired into the runtime → `#1154`.\n- **Audit-failure observability** (`#1134` first slice / `#1155`): shared `AuditLogWriter` replaces 4 copy-pasted empty-catch `SafeLogAsync`, logging at Warning on a thrown exception or returned failed `Result` while preserving never-crash.\n- Seeded: `#1149` (idempotency contract ADR), `#1150` (packaging trim-doc drift), `#1152` (Queue/V1 validator bypass), `#1154` (MCP hash wiring). `#1134` remains open for its other 6 acceptance criteria.\n\nContinuous-cycle wave (2026-05-29, 19 PRs merged, backlog cleared to zero open PRs; 2 independent adversarial reviews per PR, all findings of every severity addressed including bot comments):\n- **RFAI roadmap complete (12 of 12)**: RFAI-11 (`#983`/`#1079`) ambient channel — VS Code extension + voice prototype (ADR-0033 ratified); RFAI-12 (`#984`/`#1080`) learning loop UI, Ollama provider, ProvenanceDrawer, cohort dashboard. Both heavily pre-reviewed; all Codex inline findings audited (one open item fixed on each: 1079 git-repo path-containment, 1080 already-clean).\n- **Composable hardening**: unhandled promise rejections (`#1093`/`#1095`), `onScopeDispose` cleanup + leak fixes (`#1094`/`#1104` — Review 2/2 added startClock double-start guard, fetch-generation invalidation on dispose, isDisposed finally guards, +3 tests), FilterPanel aria-labels + single-resolve label chips (`#1097`/`#1098`).\n- **Identity/authz hardening**: an audit confirmed all 42 API controllers are claims-first with zero bypass risk. `TelemetryController`/`EgressDisclosureController` migrated onto `AuthenticatedControllerBase` (`#1109`/`#1111`); a new `ApiControllerBoundaryTests` guard enforces per-action `[Authorize]`/`[AllowAnonymous]` on non-class-authorized controllers, with explicit attributes added to AuthController/HealthController (`#1110`/`#1116`).\n- **Dependency wave**: nuget/npm minor-patch groups, YamlDotNet 18, dotnet group (`#1101`/`#1103`/`#1102`/`#1105`/`#1115`) — **fixed a recurring EF Core 8/9 split** (dependabot bumped the core package to 9.x while Sqlite/Design stayed 8.x → ambiguous `ExecuteDeleteAsync`). FluentAssertions moved to the free **7.x** line (`#1088`) rather than paid v8.

Gemini Code Assist and Codex connector bot findings addressed on delivered PRs\n- Key review fixes: 100k entity memory risk replaced with server-side GROUP BY (`#1032`), board-scoped similar-decision query (`#1038`), UnitOfWork unique constraint handlers for DailySnapshot/TomorrowNote (`#1037`/`#1035`), CancellationToken threading, reach formula correction (`#1036`), FK enforcement for provenance (`#1039`), conflict-detector create-card false positives, JSON ValueKind guards, projected WIP accounting, missing-column detection, webhook event mapping, and soft-deleted comment counts (`#1040`)\n- New shared infrastructure: `TodayController`, `DailySnapshot` entity + repository, `TomorrowNote` entity + repository, `CountByDateAsync` aggregate audit query, `GetTerminalByActionTypeAsync` and `GetPendingByOperationTargetAsync` proposal repository methods, `CountByCardIdAsync` card-comment aggregate query\n\nLatest tooling addition (2026-05-11):\n- Agentic operating layer expansion added `docs/agentic/QUESTION_PROTOCOL.md`, `docs/agentic/FAILURE_LEDGER.md`, `docs/agentic/GUIDE_UPDATE_PROTOCOL.md`, and `docs/agentic/SKILL_REGISTRY.md` so blocker questions, failed tools/checks, and guide updates are explicit artifacts instead of ad hoc chat memory.\n- `autodoc/AGENT_INDEX.md` now provides a low-context seam map, context traps, and verification hints for Taskdeck agents.\n- Codex and Claude skill mirrors now include `taskdeck-question-batch`, `taskdeck-failure-capture`, and `taskdeck-interface-map`.\n- Claude project settings now call deterministic hook scripts under `scripts/agent_hooks/` for dangerous shell-command checks and failed-tool ledger capture.\n- Codex/Claude tool parity is now documented in `docs/agentic/AGENT_TOOL_PARITY.md`, and Claude `.mcp.json` mirrors the shared MCP baseline for OpenAI docs, GitHub, Context7, Playwright, Chrome DevTools, and Docker gateway access.\n\nPrevious tooling addition (2026-04-25):\n- Codex high-autonomy workflow hardening delivered: `docs/tooling/CODEX_AUTONOMY_RUNBOOK.md` now defines issue batch orchestration, worktree workers, PR review loops, CI/comment/conflict recovery, no-silent-deferral rules, and docs rehydration.\n- Repo-local Codex skills added for issue batch orchestration, isolated issue workers, PR review loops, and CI/conflict recovery.\n- PowerShell git/worktree guard scripts and GitHub helper scripts added for Windows-safe batch execution.\n- Follow-up hardening added `scripts/github/Sync-TaskdeckProjectPriority.ps1` for Project v2 priority audit/sync and fixed `reusable-gitleaks.yml` summary indentation so the reusable workflow can create jobs instead of failing at YAML parse time.\n- Follow-up agent-ops alignment added Codex and Claude routing indexes (`.codex/README.md`, `.codex/memories/00_ACTIVE.md`, `.codex/skills/README.md`, `.claude/README.md`, `.claude/skills/README.md`), Claude high-autonomy skills, proactive Codex subagent usage guidance, and a `.mcp.json` mirror of the stable Docker MCP gateway bundle.\n\nLatest roadmap adoption (2026-04-25):\n- `taskdeck-12-week-roadmap-v4.md` was reconciled into active planning as tracker `#972` with dependency-ordered child issues `#973`--`#984`.\n- The roadmap is accepted with three corrections: proposal gating is for automation-originated writes only, exfiltration safety is separate from mutation safety, and dependency versions/empirical thresholds are measured implementation results rather than planning promises.\n- Existing shipped foundations are reused rather than reseeded: PWA/offline readiness (`#95`), voice-capture privacy anchor (`#219`), MCP hardening anchor (`#655`, for broader deferred production hardening), and test-total recertification follow-up (`#970`).\n\nRoadmap v4 first-wave delivery (2026-04-25, PRs `#985`--`#988`):\n- TST-DEBT CI annotation cleanup (`#971`/`#985`): 9 compiler warnings fixed, build warnings 22 → 12. Two rounds of adversarial review.\n- RFAI-01 safety invariants, IA cut, eval seed (`#973`/`#986`): 12 roadmap invariant tests, sidebar IA cut to 5 primary items, 15 eval golden fixtures. Three rounds of adversarial review; round 2 fixed regex capture bug in INV-04/INV-05, sidebar tests; round 3 expanded INV-01 scan scope and INV-08 injected-HttpClient detection.\n- TST-DOC test totals recertification (`#970`/`#987`): backend 5,060 / frontend 2,805 / combined 7,865+. Two rounds of adversarial review; round 2 fixed stale date and fraction notation.\n- SEC-29 CSP inline style migration complete (`#855`/`#988`): all 22 `:style` bindings migrated; `'unsafe-inline'` dropped from reverse-proxy `style-src`. Three rounds of adversarial review; round 2 fixed TdSkeleton/TdTag test assertions; round 3 migrated 7 remaining literal `style` attributes to Tailwind — zero literal style attributes remain.\n\n1. Backend advanced slices completed: automation proposals/executor, archive recovery, chat, ops/logs, workers/health.\n2. Frontend advanced views integrated: automations/chat/ops/archive and supporting APIs/types.\n3. Maintainability refactor delivered (PR #23):\n - backend shared error contracts/mapping and authenticated-user controller base\n - frontend shared query-string and error-message utilities\n4. CI hardening follow-up delivered:\n - workflow concurrency cancellation\n - frontend typecheck/build parity in CI\n - NuGet/Playwright caching and richer failure artifacts (TRX/JUnit uploads)\n\n--- GOLDEN ---\n# Taskdeck Golden Principles\n\nLast Updated: 2026-04-25\nCompanion Active Docs:\n- `docs/STATUS.md`\n- `docs/IMPLEMENTATION_MASTERPLAN.md`\n- `docs/TESTING_GUIDE.md`\n- `docs/MANUAL_TEST_CHECKLIST.md`\n- `docs/GOLDEN_PRINCIPLES.md`\n\n## Purpose\n\nThis document defines concise repository invariants that should remain stable as implementation details evolve.\nMechanical enforcement stays intentionally lightweight and focuses only on low-churn, high-signal checks.\n\n## Golden Principles\n\n- `GP-01 Layer Boundaries`\n - Keep domain/application/infrastructure/API boundaries coherent and avoid forbidden dependency direction.\n- `GP-02 Claims-First Identity`\n - Do not trust caller-supplied identity for protected resources; derive actor identity from authenticated claims.\n- `GP-03 Stable Error Contracts`\n - Preserve predictable JSON error payloads (`errorCode`, non-empty `message`) and consistent status semantics.\n- `GP-04 Test and CI Evidence`\n - Ship behavior changes with deterministic tests and run the required verification commands.\n- `GP-05 Canonical Docs Sync`\n - Keep canonical active docs aligned with shipped reality when behavior or workflow expectations change.\n- `GP-06 Review-First Automation Safety`\n - Keep automation-originated board writes proposal-first; do not introduce silent/destructive autonomy by default. Manual board UI edits remain direct and auditable.\n- `GP-07 Lightweight Mechanical Governance`\n - Prefer maintainable, low-brittleness checks over broad regex or policy sprawl.\n- `GP-08 Product Legibility Before Breadth`\n - Do not add major surface breadth ahead of a clear golden path; raw IDs in the happy path, dead-end empty states, or orphan pages without a next step are not novice-ready.\n- `GP-09 Traceable Agent Expansion`\n - Do not expose agent/autonomy breadth unless runs, policies, and resulting proposals/artifacts stay inspectable in product language.\n- `GP-10 Explicit Egress And Telemetry Boundaries`\n - Treat outbound data flow separately from mutation safety: every external destination must be disclosed/enforced, and local telemetry must reject user content by default.\n\n## Mechanical Enforcement (Current)\n\n- `scripts/check-docs-governance.mjs`\n - validates active canonical docs exist, are indexed, and keep required date stamps.\n- `scripts/check-golden-principles.mjs`\n - validates this document exists, has a `Last Updated` line, and retains core principle IDs.\n- `scripts/check-github-ops-governance.mjs`\n - validates issue-template and project-operations governance invariants.\n\n## Deferred Follow-ups\n\n- Snapshot/diff policy expansion should remain incremental and only move into CI after low-noise validation.\n- Any additional mechanical checks should be introduced only when signal quality is demonstrated.\n\n--- CODEX ACTIVE ---\n# Active Taskdeck Agent Context\n\nLast updated: 2026-06-13\n\nThis file is the Codex active-gate pointer for Taskdeck. It intentionally summarizes routing only; the canonical state remains in `docs/STATUS.md`.\n\n## Current Authority\n\n- Current shipped state: `docs/STATUS.md`\n- Roadmap and sequencing: `docs/IMPLEMENTATION_MASTERPLAN.md`\n- Stable invariants: `docs/GOLDEN_PRINCIPLES.md`\n- Dependency-aware issue execution: `docs/ISSUE_EXECUTION_GUIDE.md`\n- Testing operations: `docs/TESTING_GUIDE.md`\n- MCP/tool usage: `docs/MCP_TOOLING_GUIDE.md`\n- High-autonomy Codex workflow: `docs/tooling/CODEX_AUTONOMY_RUNBOOK.md`\n- Fast agent seam map: `autodoc/AGENT_INDEX.md`\n- Agentic protocols: `docs/agentic/QUESTION_PROTOCOL.md`, `docs/agentic/FAILURE_LEDGER.md`, `docs/agentic/GUIDE_UPDATE_PROTOCOL.md`, `docs/agentic/SKILL_REGISTRY.md`, `docs/agentic/AGENT_TOOL_PARITY.md`\n\n## Current Focus Snapshot\n\n**Direction (2026-06-13 archive pivot):** Taskdeck will not be distributed — finish it for personal use, then archive. Active sequencing is the archive-pivot **waves** (Paper UI activation → trivially-easy local run → general quality → clean archive), per the Direction sections of `docs/STATUS.md` and `docs/IMPLEMENTATION_MASTERPLAN.md`. The prior \"review-first AI / Paper backend gap delivery\" RFAI phase is **historical** — do not resume distribution/GTM/cloud/mobile work. The project thesis remains unchanged:\n\n- capture should be near-zero friction\n- automation-originated board writes must remain proposal-first and human-approved\n- provenance, confidence, side-effect disclosure, telemetry guardrails, and exfiltration controls are distinct safety surfaces\n- product legibility and trust take priority over broad new autonomy\n\n## Required Read Order\n\n1. `docs/STATUS.md`\n2. `AGENTS.md`\n3. `.codex/README.md`\n4. `docs/IMPLEMENTATION_MASTERPLAN.md`\n5. `docs/GOLDEN_PRINCIPLES.md`\n6. `docs/ISSUE_EXECUTION_GUIDE.md` when selecting or executing issues\n7. `autodoc/AGENT_INDEX.md` for cheap seam orientation\n8. the matching `.codex/skills/*/SKILL.md`\n9. feature, testing, MCP, agentic, or project-automation docs relevant to the task\n\nFor Claude Code, read `docs/STATUS.md` first, then use `.claude/README.md` and `CLAUDE.md` for Claude-specific routing.\n\n## Review Policy\n\nEvery review (self-review, adversarial, subagent) must: post findings on the PR as a comment, fix everything at every severity, check and address ALL existing PR comments (human, bot, previous reviews), and seed GitHub issues for out-of-scope findings. No \"non-blocking\" dismissals. See `AGENTS.md` Review Policy for full rules.\n\n## Agent Coordination Rules\n\n- Use spawned subagents without asking for extra permission when they are efficient or effective for safely parallelizable work.\n- When implementation needs isolation, create real git worktrees with `scripts/git/New-CodexIssueWorktree.ps1`.\n- Keep one coordinator responsible for issue selection, synthesis, docs rehydration, and final verification.\n- Do not update canonical docs for local-only guidance unless behavior, roadmap state, testing expectations, or operator workflow changed.\n- Use `docs/agentic/QUESTION_PROTOCOL.md` to batch true blockers and proceed with explicit assumptions for reversible choices.\n- Use `docs/agentic/FAILURE_LEDGER.md` for unresolved failures or workarounds that future agents should not rediscover.\n- Use `docs/agentic/AGENT_TOOL_PARITY.md` to keep Claude and Codex using equivalent capabilities through their runtime-native tools.\n","/bin/bash -lc \"pwd; cat .codex/skills/taskdeck-pr-review-loop/SKILL.md; bash scripts/check-git-env.sh; printf '\\\\n--- OUTSTANDING ---\\\\n'; sed -n '1,220p' OUTSTANDING_TASKS.md; printf '\\\\n--- STATUS ---\\\\n'; sed -n '1,220p' docs/STATUS.md; printf '\\\\n--- MASTERPLAN ---\\\\n'; sed -n '1,160p' docs/IMPLEMENTATION_MASTERPLAN.md; printf '\\\\n--- GOLDEN ---\\\\n'; sed -n '1,160p' docs/GOLDEN_PRINCIPLES.md; printf '\\\\n--- CODEX ACTIVE ---\\\\n'; sed -n '1,180p' .codex/memories/00_ACTIVE.md\"",[756],121,"call_XOnzbdl38AvyMlVkk994eXIK","71082",{"_472":757,"_92":486},"pwd; cat .codex/skills/taskdeck-pr-review-loop/SKILL.md; bash scripts/check-git-env.sh; printf '\\n--- OUTSTANDING ---\\n'; sed -n '1,220p' OUTSTANDING_TASKS.md; printf '\\n--- STATUS ---\\n'; sed -n '1,220p' docs/STATUS.md; printf '\\n--- MASTERPLAN ---\\n'; sed -n '1,160p' docs/IMPLEMENTATION_MASTERPLAN.md; printf '\\n--- GOLDEN ---\\n'; sed -n '1,160p' docs/GOLDEN_PRINCIPLES.md; printf '\\n--- CODEX ACTIVE ---\\n'; sed -n '1,180p' .codex/memories/00_ACTIVE.md",{"_429":759,"_410":411,"_431":417},{"_464":754,"_42":-5,"_435":-5,"_466":760,"_92":468},"Chunk ID: a274c6\nWall time: 0.0207 seconds\nProcess exited with code 0\nOriginal token count: 32087\nOutput:\nTotal output lines: 694\n\n/workspace/Taskdeck\n---\nname: taskdeck-pr-review-loop\ndescription: Perform Taskdeck PR self-review or fresh adversarial review, post review findings, address review comments and bot comments, verify fixes, and re-review.

Re-review the fixed diff.\n\nNever mark feedback resolved mentally without either fixing it, explaining why it is invalid, or seeding a follow-up as a GitHub issue.\n\n## Comment hygiene\n\nUse GitHub MCP for issue/PR metadata and comments when available. Use `gh` fallback when MCP is unavailable.\n\n## Rules\n\n- NEVER skip MEDIUM or LOW findings — there is no \"non-blocking\" category\n- Always check ALL existing PR comments (human, bot, previous reviews) before posting findings\n- Address every unaddressed comment: fix, invalidate with evidence, or seed a GitHub issue\n- Out-of-scope findings must be seeded as GitHub issues, never silently dropped\n- Always post a follow-up comment after fixes are pushed\n- Tech debt from reviews must be zero\n\nDo not merge PRs.

When told an item is complete, change `[ ]`→`[x]` (or remove it) and note the date in the changelog at the bottom.\n4. **Add new outstanding tasks here** when the maintainer asks you to remember something, or when substantial work is deferred. Keep entries short with a one-line \"how\" and a link to the GitHub issue/PR that holds the detail.\n5. Keep this file lean and scannable. Detail lives in the linked issues, not here.\n\nLast reviewed: 2026-06-19\n\n---\n\n## A.

Global layer shipped: `~/.claude/CLAUDE.md` laws, argv-aware deny floor (49-case tested), ESTATE.md registry, `~/.claude` now versioned (private repo claude-config).\n- 2026-07-02: **Whole-project analysis delivered + archive closeout wave seeded.** Multi-agent analysis (6 dimensions, 15 claims adversarially verified: 5 confirmed / 10 adjusted / 0 refuted) produced `docs/PROJECT_TRAJECTORY.md` + `docs/COURSE_CORRECTION.md`. Seeded issues #1269–#1278 (ARCHIVE-00..09, new `archive-closeout` label) and posted re-scope comments on 14 existing issues. Added §D above. Central findings: no checkable definition of done existed in the tracked repo; zero organic personal-usage data; the default Paper UI is the least-tested UI; the \"canonical\" exe run path has never been built; ~31% of open issues already decided-closed by the pivot but still open.\n- 2026-06-19 (later): **Merge hold lifted — deck merged.** The maintainer lifted the hold and all four PRs shipped to `main`: **#1220** (canonical-docs reconciliation; 14 Codex rounds + 3 drift sweeps), **#1219** (Paper File-away dismiss, closes #1161), **#1221** (reachable in-app Appearance theme toggle — a Paper-activation prerequisite), **#1225** (StackExchange.Redis + SignalR-backplane semver-major caps).

Two rounds of adversarial review; round 2 fixed stale date and fraction notation.\n- SEC-29 CSP inline style migration complete (`#855`/`#988`): all 22 `:style` bindings migrated; `'unsafe-inline'` dropped from reverse-proxy `style-src`. Three rounds of adversarial review; round 2 fixed TdSkeleton/TdTag test assertions; round 3 migrated 7 remaining literal `style` attributes to Tailwind — zero literal style attributes remain.\n\n1.

Manual board UI edits remain direct and auditable.\n- `GP-07 Lightweight Mechanical Governance`\n - Prefer maintainable, low-brittleness checks over broad regex or policy sprawl.\n- `GP-08 Product Legibility Before Breadth`\n - Do not add major surface breadth ahead of a clear golden path; raw IDs in the happy path, dead-end empty states, or orphan pages without a next step are not novice-ready.\n- `GP-09 Traceable Agent Expansion`\n - Do not expose agent/autonomy breadth unless runs, policies, and resulting proposals/artifacts stay inspectable in product language.\n- `GP-10 Explicit Egress And Telemetry Boundaries`\n - Treat outbound data flow separately from mutation safety: every external destination must be disclosed/enforced, and local telemetry must reject user content by default.\n\n## Mechanical Enforcement (Current)\n\n- `scripts/check-docs-governance.mjs`\n - validates active canonical docs exist, are indexed, and keep required date stamps.\n- `scripts/check-golden-principles.mjs`\n - validates this document exists, has a `Last Updated` line, and retains core principle IDs.\n- `scripts/check-github-ops-governance.mjs`\n - validates issue-template and project-operations governance invariants.\n\n## Deferred Follow-ups\n\n- Snapshot/diff policy expansion should remain incremental and only move into CI after low-noise validation.\n- Any additional mechanical checks should be introduced only when signal quality is demonstrated.\n\n--- CODEX ACTIVE ---\n# Active Taskdeck Agent Context\n\nLast updated: 2026-06-13\n\nThis file is the Codex active-gate pointer for Taskdeck. It intentionally summarizes routing only; the canonical state remains in `docs/STATUS.md`.\n\n## Current Authority\n\n- Current shipped state: `docs/STATUS.md`\n- Roadmap and sequencing: `docs/IMPLEMENTATION_MASTERPLAN.md`\n- Stable invariants: `docs/GOLDEN_PRINCIPLES.md`\n- Dependency-aware issue execution: `docs/ISSUE_EXECUTION_GUIDE.md`\n- Testing operations: `docs/TESTING_GUIDE.md`\n- MCP/tool usage: `docs/MCP_TOOLING_GUIDE.md`\n- High-autonomy Codex workflow: `docs/tooling/CODEX_AUTONOMY_RUNBOOK.md`\n- Fast agent seam map: `autodoc/AGENT_INDEX.md`\n- Agentic protocols: `docs/agentic/QUESTION_PROTOCOL.md`, `docs/agentic/FAILURE_LEDGER.md`, `docs/agentic/GUIDE_UPDATE_PROTOCOL.md`, `docs/agentic/SKILL_REGISTRY.md`, `docs/agentic/AGENT_TOOL_PARITY.md`\n\n## Current Focus Snapshot\n\n**Direction (2026-06-13 archive pivot):** Taskdeck will not be distributed — finish it for personal use, then archive. Active sequencing is the archive-pivot **waves** (Paper UI activation → trivially-easy local run → general quality → clean archive), per the Direction sections of `docs/STATUS.md` and `docs/IMPLEMENTATION_MASTERPLAN.md`. The prior \"review-first AI / Paper backend gap delivery\" RFAI phase is **historical** — do not resume distribution/GTM/cloud/mobile work. The project thesis remains unchanged:\n\n- capture should be near-zero friction\n- automation-originated board writes must remain proposal-first and human-approved\n- provenance, confidence, side-effect disclosure, telemetry guardrails, and exfiltration controls are distinct safety surfaces\n- product legibility and trust take priority over broad new autonomy\n\n## Required Read Order\n\n1. `docs/STATUS.md`\n2. `AGENTS.md`\n3. `.codex/README.md`\n4. `docs/IMPLEMENTATION_MASTERPLAN.md`\n5. `docs/GOLDEN_PRINCIPLES.md`\n6. `docs/ISSUE_EXECUTION_GUIDE.md` when selecting or executing issues\n7. `autodoc/AGENT_INDEX.md` for cheap seam orientation\n8. the matching `.codex/skills/*/SKILL.md`\n9. feature, testing, MCP, agentic, or project-automation docs relevant to the task\n\nFor Claude Code, read `docs/STATUS.md` first, then use `.claude/README.md` and `CLAUDE.md` for Claude-specific routing.\n\n## Review Policy\n\nEvery review (self-review, adversarial, subagent) must: post findings on the PR as a comment, fix everything at every severity, check and address ALL existing PR comments (human, bot, previous reviews), and seed GitHub issues for out-of-scope findings. No \"non-blocking\" dismissals. See `AGENTS.md` Review Policy for full rules.\n\n## Agent Coordination Rules\n\n- Use spawned subagents without asking for extra permission when they are efficient or effective for safely parallelizable work.\n- When implementation needs isolation, create real git worktrees with `scripts/git/New-CodexIssueWorktree.ps1`.\n- Keep one coordinator responsible for issue selection, synthesis, docs rehydration, and final verification.\n- Do not update canonical docs for local-only guidance unless behavior, roadmap state, testing expectations, or operator workflow changed.\n- Use `docs/agentic/QUESTION_PROTOCOL.md` to batch true blockers and proceed with explicit assumptions for reversible choices.\n- Use `docs/agentic/FAILURE_LEDGER.md` for unresolved failures or workarounds that future agents should not rediscover.\n- Use `docs/agentic/AGENT_TOOL_PARITY.md` to keep Claude and Codex using equivalent capabilities through their runtime-native tools.\n",{"_429":762,"_410":411,"_431":417},{"_489":763,"_464":754,"_42":-5,"_435":-5,"_193":491,"_492":-5,"_92":493},"{\"cmd\": \"pwd; cat .codex/skills/taskdeck-pr-review-loop/SKILL.md; bash scripts/check-git-env.sh; printf '\\\\n--- OUTSTANDING ---\\\\n'; sed -n '1,220p' OUTSTANDING_TASKS.md; printf '\\\\n--- STATUS ---\\\\n'; sed -n '1,220p' docs/STATUS.md; printf '\\\\n--- MASTERPLAN ---\\\\n'; sed -n '1,160p' docs/IMPLEMENTATION_MASTERPLAN.md; printf '\\\\n--- GOLDEN ---\\\\n'; sed -n '1,160p' docs/GOLDEN_PRINCIPLES.md; printf '\\\\n--- CODEX ACTIVE ---\\\\n'; sed -n '1,180p' .codex/memories/00_ACTIVE.md\", \"workdir\": \"/workspace/Taskdeck\", \"yield_time_ms\": 1000, \"max_output_tokens\": 30000}",{"_429":765,"_410":411,"_431":417},{"_432":766,"_434":-5,"_42":-5,"_435":-5,"_436":767,"_96":93,"_92":438},[768],"commentary",{"_46":769,"_92":441},"I’m using the `taskdeck-pr-review-loop` skill because this is a PR follow-up/review-triggered task.",{"_429":771,"_410":411,"_431":417},{"_42":772,"_436":767,"_46":769,"_92":446},"msg_081b51497052012e016a5461379fcc8194a0cd803835617555",{"_429":774,"_410":411,"_431":417},{"_432":-5,"_449":775,"_42":-5,"_435":-5,"_451":776,"_92":453},"gAAAAABqVGE3xts7ubs5QYCqFFVLw8a-n8U69fAaTAqh9kffvPxwWs-pfkPRUU0F8ebk5mAnAGv8dXvBi_t7fPx3d-ToDBjVfNMpD14Zdd2LcY0mgSPDA_lHfq5qtPj3DfCTyKTKWpGDrYRMuoO4u8HwR7czyQ-q3SvEVDCTlF56sb17j4nc_cFM5i8KGqs2Ga9ELs4ov5R7AP854XScHFze-c2ieCRpnN1hUBDpItYtfFo1Si8QUCwkd_bCTiAzXI0VJwann316-uFFJXk2rrXMPN76LBuCufUEylwzUPb6agvEljNuhru3SRceD0vnQrVEddYGS9rcizWVQmEvClJV2Zw-6fCV1enVskhS-K3uTofZAPZqswqdy-OoYiVBcXNZQ-pRTQRAesJXuu6mPVbv8Z3zCDZf4bmoYvXmFlkZcjb1kkyJOxf9wk4_-EUYCtmIWuaguEWeXnb1Ip5AAjKMHpoJC9suruew1-PSND6FXtu4A_rn__dHJ-_pt4Oni4ZKPpG2XnbKBV0bxf_nsi1yq4gFK7VcgZAs6eS7WGo0VJhWGDzlSUE0sdY_NsI_wrP8af2GWt6rZcrByvHlfDCMy0IF9ZFDq-U7WM9gHtjJHIiovP7IguLrSawtxo7aCiRxm1RGiAcbbUG-EPdbbD2X1uNhfLBuzYts9uc9sDms3OgtGasvl_oRThlDEbvbL3nG4G-mzWC2Zl78ib8q0zXBgqd6Kr2RtVJCUbrONTAjOAxoHqALxY9RgitfcHWiuVVoaVCoXwDiVgCE9pw0nUFabkjZUrD5DD3Yki-asNMybefKlxgC7RSXc-zgpd4dxMJOIqUiCfxa6tn1Cb7k-7GLAWF0Cz6wmvlb3LhGxHyaMoUNEcEYRzS0pSGWsnFQy5TXP_bBHX6CCd8nbDRA_iGOqCu0ezYGBzKoGlIV9dR6htocfULh5CqVZFddYD3-SUXvNiU_qI8dBuCD7-kMSDTptGx7Hl6IpmXmUnL0gtPyHDPbIIkpMI4ydXbrTG6OMa3gRIdZMkYEEnalKPEKolO-pnrGZzUJlSSp5gd4lH08YzRHkxIy4n2D2e4e033ct2-9nP9QwdiWHOw4MVR0hdVvlZqYSqfiIdNLKrqal36lLilst302XMJ61fRNRvDsxFVbzEqIPnnsSpe_BUCoKZHf8l7RcuDzN0A3KZsdpPv-2jEUNkr4eYUjHWYKhwWwoX-3XaSZsnu032ToHNNF62sP1wlJqJuRQhmGkSNATkIroFv-Y1XWusptvEiJDtK50QOHRo1uAsVo8PeiAGR0GsLJRU7ToA_ckURpuqi9TbD_WGoSPVJMQGo=",[777],{"_46":778,"_92":456},"**Reviewing code changes**\n\nI see that I need to act on the trigger here.

After bootstrap, a caller to a Closed instance (or InviteOnly without a valid invite) gets `409` plus “account ... already exists” for a registered username/email but the stable `403` for an unused identity. That defeats the generic login contract and lets an unauthenticated remote caller enumerate accounts. **Expected fix:** authorize the restrictive policy before returning uniqueness information, while keeping invite consumption and the uniqueness check in the same transaction so a duplicate attempt rolls the invite back; add API regressions proving known and unknown identities receive the same denial without a valid authorization.\\n\\n2. **The documented “safe public-deployment default” permits remote first-user seizure.** `RegistrationPolicyService.AuthorizeNewUserAsync` unconditionally authorizes whichever request first inserts the bootstrap singleton (`RegistrationPolicyService.cs:38-42`), including a remote request. The Railway/Render guidance then exposes a fresh instance at a public URL and labels `Closed` safe (`deploy/railway.toml:8-15`, `CLOUD_DEPLOYMENT_GUIDE.md:77-110`). A scanner that reaches the service before the operator can become the only user; Closed then locks the legitimate operator out. The literal no-lockout AC is satisfied, but the resulting public-bootstrap ceremony is not safe. **Expected fix:** require a bootstrap secret/local operator action, or remove the public-safety claim and require private access controls until the owner account is created. Cover the authorized-vs-unauthorized bootstrap path.\\n\\n3. **BCrypt work is performed while a SQLite write transaction is open.** The registration policy executes a write before `BCrypt.HashPassword` at `AuthenticationService.cs:118`; the new-external-user path also hashes at line 230 inside its transaction. That lengthens the single-writer lock and can turn registration/OAuth concurrency into database-wide timeouts. Gemini's two HIGH threads (`3567833413`, `3567833416`) are valid and this finding adopts them. **Expected fix:** redesign the short transaction so expensive hashing occurs outside the write lock without weakening atomic bootstrap/invite consumption, and add a contention/rollback regression.\\n\\n### MEDIUM\\n\\n4. **The explicit FULL-tier integration coverage is incomplete.** `RegistrationGatingApiTests` integrates password registration modes/bootstrap and only sequential invite reuse. The external-login gate exists only as a mocked application test, and no integration test proves a new OAuth/OIDC identity is denied while an existing linked identity still signs in against the real policy/store. Likewise, single-use invite redemption is not raced, so the atomic SQL guarantee is unproved at the API boundary. **Expected fix:** add real-store integration coverage for new-vs-existing external identities in restrictive modes and concurrent redemption of one invite (exactly one success, one stable `403`, no orphan user/link).\\n\\n### LOW\\n\\nNo low finding.\\n\\n### Existing comments and bot triage\\n\\n- The self-review's container ownership finding is fixed by `37253d45`; the non-root command evidence is adequate.\\n- The out-of-scope full-suite failures are durably tracked in #1282 and #1335; they are not treated as green.\\n- Gemini's two BCrypt threads are valid and covered by HIGH #3.\\n- Gemini's proposed process-global static `_bootstrapClaimed` cache (`3567833418`, `3567833422`) is **invalid**. One process can host multiple database paths/test factories, a database can be restored/replaced, and separate API/CLI processes share SQLite.

Surface its open items in any summary/status/handoff; only check items off when the maintainer says they are done.\n- Read `docs/STATUS.md` for Current Focus and constraints (source of truth).\n- Use `docs/IMPLEMENTATION_MASTERPLAN.md` for roadmap context.\n- Use `docs/GOLDEN_PRINCIPLES.md` for stable repository invariants and guardrails.\n- Use `docs/ISSUE_EXECUTION_GUIDE.md` for dependency-aware issue execution order.\n- For Codex routing, read `.codex/README.md` and `.codex/memories/00_ACTIVE.md`.\n- For Claude Code routing, read `.claude/README.md` and `CLAUDE.md`.\n- For test operations, see `docs/TESTING_GUIDE.md`.\n- Precedence when instructions conflict: `docs/STATUS.md` > this file > subfolder `AGENTS.md`.\n\n## MCP tools (agent tooling)\n- See `docs/MCP_TOOLING_GUIDE.md` for tool selection rules and safe usage.\n- For high-autonomy Codex issue/PR/CI batches, see `docs/tooling/CODEX_AUTONOMY_RUNBOOK.md`.\n- For low-context agent orientation, use `autodoc/AGENT_INDEX.md`.\n- For blocker questions, unresolved failures, guide updates, and skill routing, use `docs/agentic/`.\n- MCP-first default: when an MCP tool can perform a task, use MCP before shell/CLI alternatives.\n- Prefer MCP tools over guessing:\n - OpenAI/Codex/API docs -> openaiDeveloperDocs MCP\n - Third-party library docs -> Context7 MCP\n - UI reproduction/regression -> Playwright MCP\n - Repo search -> native `rg` (ripgrep MCP unreliable on Windows; fallback to GitHub search_code)\n - Issues/PRs/workflows -> GitHub MCP (write actions only when required)\n- Fallback rule:\n - if MCP is unavailable, failing, or lacks required capability, use shell/CLI fallback and state that fallback briefly in handoff notes.\n\n## Multi-Agent / Parallel Execution (required)\n- When the Codex runtime exposes spawned subagents, use them without asking for extra permission when they are efficient for safely parallelizable work — but right-size the fan-out (start inline; a few agents, not a reflexive fleet), and keep one coordinator for synthesis and final verification.\n- Split only when work can be separated by clear ownership and can proceed without blocking the coordinator's immediate next step.\n- If spawned agents are unavailable, use explicit git worktrees plus separate Codex/Claude sessions or GitHub coding-agent tasks; do not claim subagent execution unless it actually happened.\n- Split ownership by file/module/concern so concurrent work does not overlap.\n- Keep one coordinator responsible for issue selection, synthesis, conflict resolution, docs rehydration, project status/priority sync, and final verification.\n- Do not delegate final synthesis, ownership decisions, or broad vague cleanup.\n- For batch issue execution, PR review loops, CI recovery, and docs reconciliation, follow `docs/tooling/CODEX_AUTONOMY_RUNBOOK.md`.\n\n## Project Operations Automation (required)\n- Read `docs/GITHUB_PROJECT_AUTOMATION.md` before changing project operations, issue templates, or workflow conventions.\n- Canonical project status model is: `Pending`, `Now`, `Next`, `Blocked`, `Review`, `Done`.\n- Do not introduce labels in issue templates that are not in the required label set documented in `docs/GITHUB_PROJECT_AUTOMATION.md`.\n- Priority sync is mandatory:\n - For issue project items, set project `Priority` to match the issue's single priority label (`Priority I` to `Priority V`).\n - For PR project items, derive `Priority` from linked/referenced issues; if multiple priorities exist, choose highest urgency (`I` highest); if none can be derived, set `Priority V`.\n - Before handoff, verify no issue/PR project item has empty `Priority`.\n- If workflow/status conventions change, update both:\n - `docs/GITHUB_PROJECT_AUTOMATION.md`\n - this `AGENTS.md` (only if contributor behavior expectations changed)\n\n## Local skill packs\n- Repo-local Codex skills live under `.codex/skills/` and supplement `AGENTS.md`; they do not override it. Start with `.codex/skills/README.md`.\n- Repo-local Claude Code skills live under `.claude/skills/` and mirror the same Taskdeck workflows for Claude sessions. Start with `.claude/skills/README.md`.\n- Use `.codex/skills/taskdeck-issue-batch-orchestrator` when asked to take care of many issues, pick issues, coordinate worktrees/subagents, open PRs, run review loops, or reconcile a high-autonomy batch.\n- Use `.codex/skills/taskdeck-worktree-issue-worker` when implementing a single assigned issue in an isolated worktree.\n- Use `.codex/skills/taskdeck-pr-review-loop` when reviewing PRs, spinning fresh adversarial reviewers, posting findings, or addressing review/bot comments.\n- Use `.codex/skills/taskdeck-ci-conflict-recovery` when checking failing CI, resolving PR conflicts, inspecting bot comments, or recovering blocked PRs.\n- Use `.codex/skills/taskdeck-repo-onramp` when the request is broad, the repo area is unfamiliar, or current Taskdeck reality must be reconciled before planning.\n- Use `.codex/skills/taskdeck-backend-slice` for backend/API/application/infrastructure/worker/auth behavior changes.\n- Use `.codex/skills/taskdeck-frontend-workspace-slice` for frontend shell, workspace, route, help-state, and novice-legibility work outside the core capture-review semantics.\n- Use `.codex/skills/taskdeck-capture-review-loop` when capture, inbox, proposal review, execute flow, provenance, or board handoff semantics are involved.\n- Use `.codex/skills/taskdeck-demo-regression` when a task needs the right evidence path, seeded demo state, Playwright proof, or stakeholder-facing walkthrough validation.\n- Use `.codex/skills/taskdeck-verification-doc-sync` at the end of implementation to choose the right checks, update only the right docs, and prepare the required Taskdeck handoff summary.\n- Use `.codex/skills/taskdeck-question-batch` when ambiguity needs a blocker/assumption decision instead of context-expensive question loops.\n- Use `.codex/skills/taskdeck-failure-capture` when failed tools, tests, CI, MCP, docs checks, or workarounds must be classified and surfaced.\n- Use `.codex/skills/taskdeck-interface-map` when adding, splitting, or documenting complex seams that should be findable through `autodoc/AGENT_INDEX.md`.\n\n## Work protocol (required)\n- Before edits: write a short plan (files, approach, risks, tests).\n- Keep diffs small and scoped; avoid large mixed refactors.\n- Ask only for true blockers; otherwise proceed with explicit assumptions. Use `docs/agentic/QUESTION_PROTOCOL.md`.\n- Do not silently bury failed commands or tool workarounds. Use `docs/agentic/FAILURE_LEDGER.md` when unresolved failures matter for future agents or handoff confidence.\n- Prefer incremental execution with incremental, file-scoped commits when the work spans multiple files or concerns.\n- After edits: run required checks and report results.\n- If you cannot run checks, state exactly why and what you would run.\n- In this Windows PowerShell environment, do not chain commands with `&&`; use `;` and check `$LASTEXITCODE` when failure handling matters.\n- For product-facing slices, ensure issue scope and acceptance criteria explicitly align with the current thesis (reduce maintenance overhead/capture friction and preserve review-first trust).\n\n### Windows Git Reliability Fallback\n- Run `bash scripts/check-git-env.sh` at the start of a session to validate git resolution and index.lock state.\n- In PowerShell/Codex-native sessions, prefer `powershell -File scripts/check-git-env.ps1`; the Bash script remains available for Bash shells.\n- If `git` resolves to Cygwin or produces signal/pipe-style failures, use `C:\\Program Files\\Git\\cmd\\git.exe` explicitly for repo operations (or add `C:\\Program Files\\Git\\cmd` to the front of `PATH`).\n- When running automated commits in the background terminal, append `--no-gpg-sign` to `git commit` to prevent hidden GPG pinentry prompts from freezing the process. Do NOT use `--no-verify` — pre-commit hooks must run; if a hook fails, investigate and fix the underlying issue.\n- If a commit fails because `.git/index.lock` cannot be created, first check for active `git` processes; remove `.git/index.lock` only when no git process is running. The `check-git-env.sh` script automates this detection.\n- For stacked branches with small conflict surfaces, prefer `merge` over `rebase` when branch reconciliation starts stalling (for example long-running interactive/conflict loops). Resolve conflicts once, merge, and continue delivery.\n\n### Codex Worktree Safety\n- Use `scripts/git/New-CodexIssueWorktree.ps1` to create isolated issue worktrees under `.worktrees/`.\n- First command in a Codex worktree worker session must be `powershell -File scripts/worktree_guard.ps1` (or `source scripts/worktree_guard.sh` in Bash).\n- Do not pass absolute main-checkout paths to worktree workers; derive paths from `$env:WT_PROJECT_DIR` or `git rev-parse --show-toplevel`.\n- Only the coordinator should update canonical batch docs such as `docs/STATUS.md`, `docs/IMPLEMENTATION_MASTERPLAN.md`, and `docs/TESTING_GUIDE.md` unless a worker explicitly owns a docs-only issue.\n\n### Small Mainline Exception\n- If a change is very small and low-risk (especially minor docs wording/checklist updates), do not automatically create a branch/PR.\n- If the user already asked for the change directly, it may be applied on the current branch after checking git status and keeping the diff narrow.\n- If the user did not clearly ask for the change, prompt first and offer to let the user apply it directly on `main`.\n- Only proceed with branch/PR flow for these tiny changes when the user explicitly asks for it.\n\n## Review Policy (non-negotiable)\n\nEvery code review — self-review, adversarial review, subagent review — follows these rules:\n\n1. **Post findings on the PR.** Unless the user explicitly says otherwise, when a review targets a PR, post a comment with all findings organized by severity. This is the default, not optional.\n2. **Fix everything found.** Every finding at every severity (CRITICAL, HIGH, MEDIUM, LOW) must be addressed with a fix, commit, and verification. There is no \"non-blocking\" category that gets ignored. Do not skip lower-priority findings.\n3. **Out-of-scope findings get tracked, not buried.** If a finding is real but drifts outside the PR's scope, document it and seed a GitHub issue (or add to an existing tracking issue). Never silently drop it. Tech debt from reviews must be zero.\n4. **Inspect all existing PR comments.** Before posting findings, read ALL comments on the PR — human reviews, bot comments (Dependabot, CodeQL, CI bots), and previous adversarial review threads. Address anything unaddressed: fix it, reply with invalidation evidence, or seed a tracked follow-up.\n5. **Post fix evidence.** After fixing findings, post a follow-up comment mapping each finding to its fix commit and verification result.\n\nThese rules apply equally to Claude and Codex agents, subagents, and worktree workers.\n\n## Definition of Done (non-negotiable)\n- Behavior changes ship with tests (unit/integration/E2E as appropriate).\n- Handle error cases explicitly; do not swallow failures.\n- Update docs when reality changes:\n - `docs/STATUS.md` (what is true now)\n - `docs/IMPLEMENTATION_MASTERPLAN.md` (roadmap impact / next steps)\n\n## Security baseline (always on)\n- Never trust client input for identity/authority.\n- Enforce authn/authz consistently for protected resources.\n- Validate inputs server-side; fail safely.\n- Do not log secrets, tokens, or sensitive user data.\n\n## Project Structure & Modules\n- Backend (.NET): `backend/Taskdeck.sln` with layered projects under `backend/src`\n (`Taskdeck.Api`, `Taskdeck.Application`, `Taskdeck.Domain`, `Taskdeck.Infrastructure`, `Taskdeck.Cli`).\n- Backend tests: `backend/tests` with project-per-layer test suites.\n- Frontend (Vue 3 + Vite): `frontend/taskdeck-web` with app source in `src`, static assets in `public`.\n- Docs and planning: Start with `docs/STATUS.md` (source of truth),\n `docs/IMPLEMENTATION_MASTERPLAN.md` (active roadmap), `docs/GOLDEN_PRINCIPLES.md` (stable invariants), and `docs/TESTING_GUIDE.md` (test operations).\n Historical context lives under `docs/archive/`.\n\n## Build, Test & Run\n- Backend restore/build: `dotnet restore backend/Taskdeck.sln` and `dotnet build backend/Taskdeck.sln -c Release`.\n- Backend tests (required): `dotnet test backend/Taskdeck.sln -c Release -m:1`.\n- Backend API (local): from `backend/src/Taskdeck.Api`, run `dotnet run`.\n- Frontend dev server: from `frontend/taskdeck-web`, run `npm install` once, then `npm run dev`.\n- Frontend checks (required when frontend touched): from `frontend/taskdeck-web`,\n `npm run typecheck; if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }; npm run build; if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }; npx vitest --run` (PowerShell fail-fast; do not use `&&`).\n\n## Coding Style & Naming\n- Backend: C# conventions, 4-space indentation, PascalCase for classes and public members,\n camelCase for locals and parameters. Keep layers pure (e.g., `Domain` has no infrastructure dependencies).\n- Frontend: TypeScript + Vue SFCs in `PascalCase.vue`. Use script setup and composition APIs where existing code does.\n Prefer meaningful names over abbreviations.\n- Keep formatting consistent with existing files; do not introduce new style tools without discussion.\n\n## Testing Guidelines\n- Prefer unit tests close to the corresponding project (e.g., `Taskdeck.Application.Tests` for application logic).\n- Mirror production namespaces in test namespaces and file names (e.g., `FooServiceTests.cs` for `FooService`).\n- Add coverage for new branches and error paths, especially in application services and HTTP endpoints.\n- For frontend, add tests following the existing tooling (or document gaps clearly if tests are not yet present).\n\n## Commit & Pull Request Guidelines\n- Commits: Use clear, present-tense messages (e.g., `Add booking validation to application layer`).\n Default to small focused incremental commits, often one commit per changed file with a short file-specific description.\n Keep commits small and focused; avoid large mixed-topic commits.\n If a single logical change must touch multiple files, keep the smallest practical commit set and explain why.\n Exception: for pure file move/rename batches (no content changes), one grouped commit is acceptable and preferred.\n- Pull requests: Provide a short summary, key implementation notes, and testing evidence\n (commands run, screenshots for UI changes). Link related issues/tasks where applicable.\n- Keep PRs focused and small when possible; prefer follow-up PRs for refactors or additional cleanup.\n- PRs touching CI workflows (`.github/workflows/`), infrastructure (`deploy/`, `scripts/`), or project files (`*.csproj`) auto-trigger CI Extended. Ensure CI Extended is green before merging these PRs.\n- For issue execution unless the user explicitly says otherwise: open the PR after verification is complete, then perform a deliberate reviewer-style pass on the PR diff/comments before handoff. Follow the Review Policy: post findings, fix everything, address all existing comments, and seed issues for out-of-scope items. Follow the Review Policy: post findings, fix everything, address all existing comments, and seed issues for out-of-scope items.\n\n## Output expectations (after work)\nProvide:\n- Summary of changes\n- Files touched\n- Tests added/updated\n- Commands run + results\n- Docs updated (`STATUS` / `MASTERPLAN`)\n- Notable risks or follow-ups (if any)\n\nSee `docs/tooling/FUTURE_HARNESS_BACKLOG.md` for deferred harness/MCP upgrades.\n\nSee `docs/tooling/DEVTOOLS_OBSERVABILITY_ADDON.md` for Playwright vs DevTools vs logs decision rules.\n\n",{"_429":807,"_410":411,"_431":417},{"_432":808,"_434":-5,"_42":-5,"_435":-5,"_436":-5,"_96":809,"_92":438},[810,811],"developer",{"_46":813,"_92":798},{"_46":812,"_92":798},"\n## Skills\nA skill is a set of local instructions to follow that is stored in a `SKILL.md` file. Below is the list of skills that can be used. Each entry includes a name, description, and file path so you can open the source for full instructions when using a specific skill.\n### Available skills\n- imagegen: Generate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector. Do not use when the task is better handled by editing existing SVG/vector/code-native assets, extending an established icon or logo system, or building the visual directly in HTML/CSS/canvas. (file: /opt/codex/skills/.system/imagegen/SKILL.md)\n- openai-docs: Use when the user asks how to build with OpenAI products or APIs and needs up-to-date official documentation with citations, help choosing the latest model for a use case, or model upgrade and prompt-upgrade guidance; prioritize OpenAI docs MCP tools, use bundled references only as helper context, and restrict any fallback browsing to official OpenAI domains. (file: /opt/codex/skills/.system/openai-docs/SKILL.md)\n- plugin-creator: Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, and baseline placeholders you can edit before publishing or testing. Use when Codex needs to create a new local plugin, add optional plugin structure, or generate or update repo-root `.agents/plugins/marketplace.json` entries for plugin ordering and availability metadata. (file: /opt/codex/skills/.system/plugin-creator/SKILL.md)\n- skill-creator: Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations. (file: /opt/codex/skills/.system/skill-creator/SKILL.md)\n- skill-installer: Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos). (file: /opt/codex/skills/.system/skill-installer/SKILL.md)\n- taskdeck-backend-slice: Implement Taskdeck backend changes safely. Use when changing .NET API, application, domain, infrastructure, worker, auth, provider-runtime, import-export, notification, archive, or persistence behavior. (file: /workspace/Taskdeck/.codex/skills/taskdeck-backend-slice/SKILL.md)\n- taskdeck-capture-review-loop: Protect Taskdeck's core capture-review-apply-board loop. Use when touching Inbox, capture, triage, automation proposals, proposal summaries, approve-reject-execute behavior, provenance, or board handoff semantics across backend or frontend. (file: /workspace/Taskdeck/.codex/skills/taskdeck-capture-review-loop/SKILL.md)\n- taskdeck-ci-conflict-recovery: Triage and fix Taskdeck PR failures involving CI, GitHub bot comments, merge conflicts, stale branches, flaky tests, or blocked checks. Use when the user asks Codex to check failing CI, inspect PR comments, fix conflicts, monitor runs, rerun checks, or recover PRs after review automation reports errors. (file: /workspace/Taskdeck/.codex/skills/taskdeck-ci-conflict-recovery/SKILL.md)\n- taskdeck-demo-regression: Validate Taskdeck with the smallest evidence path that proves the change. Use when a task needs seeded demo state, Playwright proof, screenshots, or stakeholder walkthrough evidence. (file: /workspace/Taskdeck/.codex/skills/taskdeck-demo-regression/SKILL.md)\n- taskdeck-failure-capture: Classify and record Taskdeck agent failures, failed commands, flaky or blocked checks, MCP/tool problems, CI failures, docs-governance warnings, and workarounds. Use whenever unresolved friction should be visible in handoff or promoted into guidance. (file: /workspace/Taskdeck/.codex/skills/taskdeck-failure-capture/SKILL.md)\n- taskdeck-frontend-workspace-slice: Implement Taskdeck frontend shell and workspace changes. Use when changing Vue routes, stores, components, Home, Today, Boards, workspace-mode flows, keyboard behavior, help states, or novice-first product legibility outside the core capture-review semantics. (file: /workspace/Taskdeck/.codex/skills/taskdeck-frontend-workspace-slice/SKILL.md)\n- taskdeck-interface-map: Maintain Taskdeck's agent-facing interface maps. Use when adding, splitting, refactoring, or documenting complex domains so future agents can find entry points, invariants, edit seams, traps, and verification commands without bulk-reading the repo. (file: /workspace/Taskdeck/.codex/skills/taskdeck-interface-map/SKILL.md)\n- taskdeck-issue-batch-orchestrator: Coordinate high-autonomy Taskdeck issue batches from selection through PR review and handoff. Use when the user asks Codex to take care of many issues, pick next issues, run a batch, coordinate subagents/worktrees, seed follow-ups, reconcile GitHub project status, or automate issue-to-PR execution across multiple independent workstreams. (file: /workspace/Taskdeck/.codex/skills/taskdeck-issue-batch-orchestrator/SKILL.md)\n- taskdeck-pr-review-loop: Perform Taskdeck PR self-review or fresh adversarial review, post review findings, address review comments and bot comments, verify fixes, and re-review. Use when the user asks to review PRs, spin fresh reviewers, check comments, address feedback, or run another adversarial pass on sensitive or failing work. (file: /workspace/Taskdeck/.codex/skills/taskdeck-pr-review-loop/SKILL.md)\n- taskdeck-question-batch: Decide whether a Taskdeck agent should ask the user, proceed with a documented assumption, or stop for safety. Use when a task is broad, underspecified, has possible product/security/schema ambiguity, or risks context-expensive question loops. (file: /workspace/Taskdeck/.codex/skills/taskdeck-question-batch/SKILL.md)\n- taskdeck-repo-onramp: Orient to the Taskdeck repo before editing. Use when starting a session, entering an unfamiliar area, reconciling a broad request against current reality, or turning a vague task into a scoped plan. (file: /workspace/Taskdeck/.codex/skills/taskdeck-repo-onramp/SKILL.md)\n- taskdeck-verification-doc-sync: Finish a Taskdeck change with the right checks and doc updates. Use at the end of implementation to choose verification scope, decide whether canonical docs changed, and prepare the required handoff summary. (file: /workspace/Taskdeck/.codex/skills/taskdeck-verification-doc-sync/SKILL.md)\n- taskdeck-worktree-issue-worker: Implement one Taskdeck GitHub issue in an isolated worktree with focused ownership, small commits, tests, PR creation, and handoff. Use when a coordinator assigns Codex a single issue, asks for issue-to-PR execution, or launches a worker/subagent for backend, frontend, docs, or testing implementation. (file: /workspace/Taskdeck/.codex/skills/taskdeck-worktree-issue-worker/SKILL.md)\n### How to use skills\n- Discovery: The list above is the skills available in this session (name + description + file path). Skill bodies live on disk at the listed paths.\n- Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned.\n- Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback.\n- How to use a skill (progressive disclosure):\n 1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow.\n 2) When `SKILL.md` references relative paths (e.g., `scripts/foo.py`), resolve them relative to the skill directory listed above first, and only consider other paths if needed.\n 3) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything.\n 4) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks.\n 5) If `assets/` or templates exist, reuse them instead of recreating from scratch.\n- Coordination and sequencing:\n - If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them.\n - Announce which skill(s) you're using and why (one short line).

Per the overnight authority, it requires maintainer review and is **not eligible for autonomous merge**.\n\n## Summary\n\n- Add `Auth:Registration:Mode` with `Open` (application default), `InviteOnly`, and `Closed`.\n- Require an operator-minted invite for the first owner in restrictive modes, eliminating remote first-user takeover while preserving Open first-user behavior.\n- Add expiring, single-use, SHA-256-hashed invite codes and `taskdeck invite create --expires N`.\n- Authorize restrictive registration before checking username/email uniqueness, preventing the anonymous account-enumeration oracle while keeping invite consumption and uniqueness in one rollback-safe transaction.\n- Move password BCrypt work outside the SQLite write transaction.\n- Gate only new password/external identities; existing password and linked OAuth/OIDC users continue to sign in in every mode.\n- Package the CLI in both container images, set public deployment templates to `Closed`, and document the private-shell/non-root first-owner ceremony.\n\nAssumption: v0.1 invite minting is local-operator CLI-only, centralized behind `IRegistrationPolicyService`. Reason: #1297 explicitly permits CLI-only and this is smaller than a new remote admin endpoint. Reversible by adding an authenticated admin transport over the same service.\n\n## Verification\n\nPassed on final local commit `6156022b`:\n\n- `dotnet build backend/Taskdeck.sln -c Release --no-restore`\n- Application auth/registration/external/OIDC/account-linking tests: **152/152**\n- Registration/auth/migration API tests: **43/43**\n- Registration gating API integration tests: **8/8**\n- Full CLI project: **99/99**\n- Concurrent single-invite redemption: **10/10 repeated**; every run persisted exactly one redeemer\n- Full serialized backend suite: **6,855 passed, 0 failed, 1 known skipped** (INV-09 architecture invariant)\n - Domain 1,625; Application 3,234; API 1,857; CLI 99; Architecture 20 passed/1 skipped; Integration 20\n- `node scripts/check-docs-governance.mjs`\n- `git diff --check origin/issue-1297/registration-gating...HEAD`\n- `docker compose ... config --quiet` with required test secrets\n\nThe two earlier full-suite runs were not green; their unrelated failure families remain tracked in #1282 and #1335. The clean final full-suite run passed them, but the tracking issues are not dismissed.\n\nGitHub status after this push:\n\n- Required CI is **20/20 green** on `6156022b`, including Linux/Windows API integration and E2E Smoke.\n- CI Extended has a shared workflow startup failure tracked in #1330. This PR is not fully green while that required/no-failure policy remains unresolved.\n\n## Review fixes\n\n- `1b2a7f13`: fixes all four fresh FULL-tier findings—account enumeration, remote bootstrap takeover, BCrypt transaction duration, and missing real-store/concurrency coverage.\n- `6156022b`: updates operator, container, cloud, authentication, configuration, and data-model guidance.\n- Gemini BCrypt threads were fixed and resolved.\n- Gemini's static process-global bootstrap cache suggestion was invalidated with cross-process/multi-database/restore evidence and resolved; the database singleton remains authoritative.\n\n## Review notes\n\n- New external identities cannot redeem an invite directly in this v0.1 CLI-only flow. Invitees register with password first and then link OAuth/OIDC. Existing linked external identities always continue to work.\n- The current frontend cannot submit `inviteCode`; #1301 owns that UI and remains a deployment/user-completeness dependency.\n- `docs/STATUS.md`, `docs/IMPLEMENTATION_MASTERPLAN.md`, and `.codex/memories/00_ACTIVE.md` were intentionally not changed: their direction sections are superseded and land through #1296/#1328; canonical batch docs remain coordinator-owned.\n\n## Checklist\n\n- [x] Behavior changes have unit/integration/concurrency coverage\n- [x] Migration has fresh/existing-database coverage\n- [x] Restrictive first-owner ceremony is local/operator-authorized\n- [x] Documentation updated\n- [x] Fresh FULL-tier findings and all existing bot threads addressed with evidence\n- [x] Required CI green on final commit\n- [ ] Fresh Codex review round on final commit complete\n- [ ] Maintainer approval for auth-policy convention/migration\n\nCloses #1297\n## Self-review findings\n\nI reviewed the complete diff against #1297, including the auth boundary, migration/bootstrap behavior, container packaging, deployment defaults, tests, and all current PR comments/reviews (none existed when this review began).\n\n### MEDIUM — fixed: container invite command could change SQLite file ownership\n\nThe initially documented container command ran the packaged CLI as root. On SQLite deployments that can leave WAL/journal sidecars owned by root, preventing the non-root API process from reopening the database.\n\n**Fix evidence:** commit `37253d45` changes Compose examples to UID `10001:10001` and production-image examples to `gosu taskdeck`.\n\n**Verification:** the packaged CLI minted an invite successfully as UID 10001 in `taskdeck-registration-api:test` and UID 1001 in `taskdeck-registration-prod:test`; docs governance and `git diff --check` also pass.\n\nNo other actionable findings were identified in this self-review. The PR remains blocked from merge pending required CI, a fresh independent adversarial review, and maintainer approval for the auth-policy convention/migration. The full-suite failures listed in the PR body also remain explicitly unresolved and are not being treated as green.\n![high](https://www.gstatic.com/codereviewagent/high-priority.svg)\n\nPerforming CPU-intensive cryptographic operations like `BCrypt.HashPassword` inside an active database transaction holds database locks and connection pool resources open much longer than necessary.

It adds a RegistrationPolicyService to authorize new users, supports atomic first-user bootstrapping, and implements CLI commands to generate one-time registration invites. The feedback highlights opportunities to optimize performance and resource utilization by moving CPU-intensive password hashing operations outside of active database transactions in AuthenticationService. Additionally, it is recommended to cache the claimed state of the first-user bootstrap in-memory within RegistrationPolicyService to avoid redundant database write attempts on subsequent registrations.\n\n> [!IMPORTANT]\n> The [consumer version of Gemini Code Assist on GitHub](https://developers.google.com/gemini-code-assist/docs/review-repo-code) is being sunset.

This PR remains never-merge and still requires a fresh independent FULL-tier review, final CI, and maintainer approval.\n## Fresh FULL-tier adversarial review — changes requested\n\nI reviewed #1297's acceptance criteria, the complete 49-file diff at `37253d45`, auth/controller/service/SQLite transaction boundaries, migration upgrade/fresh-install behavior, CLI and container packaging, deployment guidance, targeted/full-suite evidence, and every current top-level/review/bot comment.\n\n### CRITICAL\n\nNo critical finding.\n\n### HIGH\n\n1. **Restrictive modes expose an account-enumeration oracle.** `AuthenticationService.RegisterAsync` checks `Users.ExistsAsync` at `backend/src/Taskdeck.Application/Services/AuthenticationService.cs:101-103` before the registration policy at lines 105-115. After bootstrap, a caller to a Closed instance (or InviteOnly without a valid invite) gets `409` plus “account ... already exists” for a registered username/email but the stable `403` for an unused identity. That defeats the generic login contract and lets an unauthenticated remote caller enumerate accounts. **Expected fix:** authorize the restrictive policy before returning uniqueness information, while keeping invite consumption and the uniqueness check in the same transaction so a duplicate attempt rolls the invite back; add API regressions proving known and unknown identities receive the same denial without a valid authorization.\n\n2. **The documented “safe public-deployment default” permits remote first-user seizure.** `RegistrationPolicyService.AuthorizeNewUserAsync` unconditionally authorizes whichever request first inserts the bootstrap singleton (`RegistrationPolicyService.cs:38-42`), including a remote request. The Railway/Render guidance then exposes a fresh instance at a public URL and labels `Closed` safe (`deploy/railway.toml:8-15`, `CLOUD_DEPLOYMENT_GUIDE.md:77-110`). A scanner that reaches the service before the operator can become the only user; Closed then locks the legitimate operator out. The literal no-lockout AC is satisfied, but the resulting public-bootstrap ceremony is not safe. **Expected fix:** require a bootstrap secret/local operator action, or remove the public-safety claim and require private access controls until the owner account is created. Cover the authorized-vs-unauthorized bootstrap path.\n\n3. **BCrypt work is performed while a SQLite write transaction is open.** The registration policy executes a write before `BCrypt.HashPassword` at `AuthenticationService.cs:118`; the new-external-user path also hashes at line 230 inside its transaction. That lengthens the single-writer lock and can turn registration/OAuth concurrency into database-wide timeouts. Gemini's two HIGH threads (`3567833413`, `3567833416`) are valid and this finding adopts them. **Expected fix:** redesign the short transaction so expensive hashing occurs outside the write lock without weakening atomic bootstrap/invite consumption, and add a contention/rollback regression.\n\n### MEDIUM\n\n4. **The explicit FULL-tier integration coverage is incomplete.** `RegistrationGatingApiTests` integrates password registration modes/bootstrap and only sequential invite reuse. The external-login gate exists only as a mocked application test, and no integration test proves a new OAuth/OIDC identity is denied while an existing linked identity still signs in against the real policy/store. Likewise, single-use invite redemption is not raced, so the atomic SQL guarantee is unproved at the API boundary. **Expected fix:** add real-store integration coverage for new-vs-existing external identities in restrictive modes and concurrent redemption of one invite (exactly one success, one stable `403`, no orphan user/link).\n\n### LOW\n\nNo low finding.\n\n### Existing comments and bot triage\n\n- The self-review's container ownership finding is fixed by `37253d45`; the non-root command evidence is adequate.\n- The out-of-scope full-suite failures are durably tracked in #1282 and #1335; they are not treated as green.\n- Gemini's two BCrypt threads are valid and covered by HIGH #3.\n- Gemini's proposed process-global static `_bootstrapClaimed` cache (`3567833418`, `3567833422`) is **invalid**. One process can host multiple database paths/test factories, a database can be restored/replaced, and separate API/CLI processes share SQLite. A static flag would let one database's state suppress bootstrap checks for another and would make the process cache—not the transactionally persisted singleton—the authority. Do not implement that suggestion; optimize only with database-scoped, rollback-safe state if measurement justifies it.\n- The current frontend cannot submit `inviteCode`, but #1301 explicitly owns and sequences that UI work after #1297; treat it as a merge/deployment dependency rather than silently claiming this PR is independently user-complete.\n\n### Verification\n\n- Fresh reviewer run: application auth/registration/external/OIDC/account-linking filter **90/90 passed**.\n- Fresh reviewer run: registration-gating + migration API filter **14/14 passed**.\n- Fresh reviewer run: invite CLI filter **4/4 passed**.\n- GitHub checks at submission: all completed jobs green; Windows API Integration still pending.\n- The PR body correctly records two non-green full backend runs. This review does not approve merge; the PR remains maintainer-only and changes are requested.\nFixed in 1b2a7f13. RegisterAsync now computes BCrypt before BeginTransactionAsync, then performs restrictive authorization and uniqueness inside the same transaction so duplicate identities roll invite consumption back. Verified by the duplicate-invite rollback integration test, 10/10 concurrent-redemption repetitions, and the green 6,855-test serialized backend run.\nFixed in 1b2a7f13. ExternalLoginAsync now computes the random unusable BCrypt hash before opening the SQLite write transaction. The real-store external-login regression proves a new identity is gated while an existing linked identity still signs in; the full serialized backend suite is green.\nNot implemented because a process-global cache is not a safe authority. One process hosts multiple database paths in test factories, a database can be restored or replaced, and API/CLI processes share SQLite. A static bit could suppress bootstrap checks for the wrong database. The transactionally persisted singleton remains authoritative; 10/10 real-SQLite contention repetitions and the full serialized suite are green.\nNot implemented for the cross-process and multi-database correctness reasons above. The cache cannot know whether the active database was switched, restored, or claimed by another process, and it would outlive transaction rollback semantics. The database-scoped INSERT OR IGNORE remains inside the short transaction; BCrypt was moved out, and 10/10 concurrent invite races plus the 6,855-test serialized run passed.\n## FULL-tier review fix evidence — final head `6156022b`\n\nAll findings from review https://github.com/Chris0Jeky/Taskdeck/pull/1334#pullrequestreview-4681529933 and all four pre-push bot threads are addressed.\n\n1. **HIGH — account enumeration:** `1b2a7f13` authorizes restrictive registration before username/email uniqueness disclosure. Known and unknown identities now receive the same stable `403` without a valid invite in both Closed and InviteOnly. Valid-invite duplicate attempts roll back consumption.\n2. **HIGH — remote first-user takeover:** `1b2a7f13` requires an operator-minted invite for the first owner in both restrictive modes; Open remains unchanged. `6156022b` documents private-shell, non-root provisioning and removes unconditional-bootstrap claims.\n3. **HIGH — BCrypt inside SQLite transaction:** `1b2a7f13` precomputes password hashes before `BeginTransactionAsync` for password and new-external registration. Invite/bootstrap authorization, uniqueness, and writes remain atomic.\n4. **MEDIUM — missing real-store/concurrency proof:** `1b2a7f13` adds real SQLite coverage for new-vs-existing external identities, concurrent redemption of one invite (exactly one persisted user), duplicate rollback/reuse, and restrictive known-vs-unknown denial.\n5. **Gemini static cache suggestions:** invalidated, not implemented. A process-global flag is unsafe across multiple database paths, restores/replacements, and API/CLI processes; the persisted database singleton remains authoritative.\n\nVerification on the pushed commits:\n\n- build green;\n- 152/152 focused application auth tests;\n- 43/43 API auth/registration/migration tests;\n- 99/99 CLI tests;\n- concurrent redemption 10/10 repeated;\n- full serialized backend: 6,855 passed, 0 failed, 1 known INV-09 skip;\n- docs governance, diff check, and Compose render green.\n\nEvery existing inline thread has a direct reply and is resolved.

Known and unknown identities now receive the same stable `403` without a valid invite in both Closed and InviteOnly. Valid-invite duplicate attempts roll back consumption.\n2. **HIGH — remote first-user takeover:** `1b2a7f13` requires an operator-minted invite for the first owner in both restrictive modes; Open remains unchanged. `6156022b` documents private-shell, non-root provisioning and removes unconditional-bootstrap claims.\n3. **HIGH — BCrypt inside SQLite transaction:** `1b2a7f13` precomputes password hashes before `BeginTransactionAsync` for password and new-external registration. Invite/bootstrap authorization, uniqueness, and writes remain atomic.\n4. **MEDIUM — missing real-store/concurrency proof:** `1b2a7f13` adds real SQLite coverage for new-vs-existing external identities, concurrent redemption of one invite (exactly one persisted user), duplicate rollback/reuse, and restrictive known-vs-unknown denial.\n5. **Gemini static cache suggestions:** invalidated, not implemented.

CI Extended remains a shared workflow startup failure tracked by #1330, so this PR is not described as fully green and remains **never merge tonight**.","Not implemented for the cross-process and multi-database correctness reasons above.

Verified by the duplicate-invite rollback integration test, 10/10 concurrent-redemption repetitions, and the green 6,855-test serialized backend run.","## Fresh FULL-tier adversarial review — changes requested\n\nI reviewed #1297's acceptance criteria, the complete 49-file diff at `37253d45`, auth/controller/service/SQLite transaction boundaries, migration upgrade/fresh-install behavior, CLI and container packaging, deployment guidance, targeted/full-suite evidence, and every current top-level/review/bot comment.\n\n### CRITICAL\n\nNo critical finding.\n\n### HIGH\n\n1. **Restrictive modes expose an account-enumeration oracle.** `AuthenticationService.RegisterAsync` checks `Users.ExistsAsync` at `backend/src/Taskdeck.Application/Services/AuthenticationService.cs:101-103` before the registration policy at lines 105-115. After bootstrap, a caller to a Closed instance (or InviteOnly without a valid invite) gets `409` plus “account ... already exists” for a registered username/email but the stable `403` for an unused identity. That defeats the generic login contract and lets an unauthenticated remote caller enumerate accounts. **Expected fix:** authorize the restrictive policy before returning uniqueness information, while keeping invite consumption and the uniqueness check in the same transaction so a duplicate attempt rolls the invite back; add API regressions proving known and unknown identities receive the same denial without a valid authorization.\n\n2. **The documented “safe public-deployment default” permits remote first-user seizure.** `RegistrationPolicyService.AuthorizeNewUserAsync` unconditionally authorizes whichever request first inserts the bootstrap singleton (`RegistrationPolicyService.cs:38-42`), including a remote request. The Railway/Render guidance then exposes a fresh instance at a public URL and labels `Closed` safe (`deploy/railway.toml:8-15`, `CLOUD_DEPLOYMENT_GUIDE.md:77-110`). A scanner that reaches the service before the operator can become the only user; Closed then locks the legitimate operator out. The literal no-lockout AC is satisfied, but the resulting public-bootstrap ceremony is not safe. **Expected fix:** require a bootstrap secret/local operator action, or remove the public-safety claim and require private access controls until the owner account is created. Cover the authorized-vs-unauthorized bootstrap path.\n\n3. **BCrypt work is performed while a SQLite write transaction is open.** The registration policy executes a write before `BCrypt.HashPassword` at `AuthenticationService.cs:118`; the new-external-user path also hashes at line 230 inside its transaction. That lengthens the single-writer lock and can turn registration/OAuth concurrency into database-wide timeouts. Gemini's two HIGH threads (`3567833413`, `3567833416`) are valid and this finding adopts them. **Expected fix:** redesign the short transaction so expensive hashing occurs outside the write lock without weakening atomic bootstrap/invite consumption, and add a contention/rollback regression.\n\n### MEDIUM\n\n4. **The explicit FULL-tier integration coverage is incomplete.** `RegistrationGatingApiTests` integrates password registration modes/bootstrap and only sequential invite reuse. The external-login gate exists only as a mocked application test, and no integration test proves a new OAuth/OIDC identity is denied while an existing linked identity still signs in against the real policy/store. Likewise, single-use invite redemption is not raced, so the atomic SQL guarantee is unproved at the API boundary. **Expected fix:** add real-store integration coverage for new-vs-existing external identities in restrictive modes and concurrent redemption of one invite (exactly one success, one stable `403`, no orphan user/link).\n\n### LOW\n\nNo low finding.\n\n### Existing comments and bot triage\n\n- The self-review's container ownership finding is fixed by `37253d45`; the non-root command evidence is adequate.\n- The out-of-scope full-suite failures are durably tracked in #1282 and #1335; they are not treated as green.\n- Gemini's two BCrypt threads are valid and covered by HIGH #3.\n- Gemini's proposed process-global static `_bootstrapClaimed` cache (`3567833418`, `3567833422`) is **invalid**. One process can host multiple database paths/test factories, a database can be restored/replaced, and separate API/CLI processes share SQLite. A static flag would let one database's state suppress bootstrap checks for another and would make the process cache—not the transactionally persisted singleton—the authority. Do not implement that suggestion; optimize only with database-scoped, rollback-safe state if measurement justifies it.\n- The current frontend cannot submit `inviteCode`, but #1301 explicitly owns and sequences that UI work after #1297; treat it as a merge/deployment dependency rather than silently claiming this PR is independently user-complete.\n\n### Verification\n\n- Fresh reviewer run: application auth/registration/external/OIDC/account-linking filter **90/90 passed**.\n- Fresh reviewer run: registration-gating + migration API filter **14/14 passed**.\n- Fresh reviewer run: invite CLI filter **4/4 passed**.\n- GitHub checks at submission: all completed jobs green; Windows API Integration still pending.\n- The PR body correctly records two non-green full backend runs. This review does not approve merge; the PR remains maintainer-only and changes are requested.","Out-of-scope full-suite failures are now durably tracked rather than dismissed:\n\n- concurrent card creation HTTP 500 -> existing test-harness/concurrency issue #1282;\n- hosted LLM worker pre-claim and delayed presence event after reset -> new focused issue #1335.\n\nThe exact tests passing narrowly does not make either full run green. This PR remains never-merge and still requires a fresh independent FULL-tier review, final CI, and maintainer approval.","## Code Review\n\nThis pull request introduces registration gating to Taskdeck, allowing operators to configure the registration mode as Open, InviteOnly, or Closed. It adds a RegistrationPolicyService to authorize new users, supports atomic first-user bootstrapping, and implements CLI commands to generate one-time registration invites. The feedback highlights opportunities to optimize performance and resource utilization by moving CPU-intensive password hashing operations outside of active database transactions in AuthenticationService. Additionally, it is recommended to cache the claimed state of the first-user bootstrap in-memory within RegistrationPolicyService to avoid redundant database write attempts on subsequent registrations.\n\n> [!IMPORTANT]\n> The [consumer version of Gemini Code Assist on GitHub](https://developers.google.com/gemini-code-assist/docs/review-repo-code) is being sunset. Starting **June 18, 2026**, new organization installations will be blocked, and all code review activity will officially cease on **July 17, 2026**.\n> For more details on the timeline and next steps, please review the [Help Documentation](https://developers.google.com/gemini-code-assist/docs/deprecations/consumer-code-review).","![medium](https://www.gstatic.com/codereviewagent/medium-priority.svg)\n\nOnce the first-user bootstrap has been claimed and committed, any subsequent registration attempt will result in `TryClaimFirstUserBootstrapAsync` returning `false` (due to the unique constraint on the singleton ID). However, attempting this `INSERT OR IGNORE` on every single registration is a database write operation that incurs lock contention and performance overhead, especially under load or spam.\n\nBy caching the claimed state in-memory once `TryClaimFirstUserBootstrapAsync` returns `false` (indicating the row already exists and is committed), we can completely bypass the database write attempt for all future registrations.\n\n```c#\n if (_bootstrapClaimed)\n {\n // Skip database write attempt if the bootstrap has already been claimed and committed\n }\n else if (await _store.TryClaimFirstUserBootstrapAsync(now, cancellationToken))\n {\n return Result.Success();\n }\n else\n {\n _bootstrapClaimed = true;\n }\n```","![medium](https://www.gstatic.com/codereviewagent/medium-priority.svg)\n\nAdd a static cache field to track whether the first-user bootstrap has already been claimed and committed.

On SQLite deployments that can leave WAL/journal sidecars owned by root, preventing the non-root API process from reopening the database.\n\n**Fix evidence:** commit `37253d45` changes Compose examples to UID `10001:10001` and production-image examples to `gosu taskdeck`.\n\n**Verification:** the packaged CLI minted an invite successfully as UID 10001 in `taskdeck-registration-api:test` and UID 1001 in `taskdeck-registration-prod:test`; docs governance and `git diff --check` also pass.\n\nNo other actionable findings were identified in this self-review.
