docs: record v0.2.60 production acceptance [skip ci]

- nexus_create_task: Fassade → bridge.CreateTaskAsync()
- nexus_create_child_task: Fassade → bridge.CreateChildTaskAsync()
- nexus_update_status: Enum-validiert via NexusMcpTaskState (0-4)
  MCP SDK lehnt ungültige Integer-Werte vor Tool-Aufruf ab
  ToStateString() hat exhaustiven Switch + InvalidEnumArgumentException-Fallback
  Bridge erzwingt CanChangeState-Autorisierung (nur iris/bao/nexus-system)
- nexus_append_activity: Fassade → bridge.AppendActivityAsync()
- nexus_handoff: Fassade → bridge.HandoffAsync()

Neue NexusMcpTaskStateHelper.IsDefined() für testbare State-Validierung.
Alle 5 Tools via [McpServerTool] auf McpServerToolType-Klasse registriert.
Keine Businesslogik-Duplizierung — volle Delegation an ITaskBridgeService.
Build: 0w 0e.

-#
-# Triggers:
-#   1. AUTOMATIC after successful CI on main (workflow_run)
-#      → Uses safe defaults: patch bump, all services, main ref.
-#      → Commits marked with [skip ci] are filtered at job level
-#        (prevents version-bump loops).
-#   2. MANUAL via workflow_dispatch with full parameter control.
-#
-# Concurrency: one deploy at a time.
-#   Queued deploys wait — no race conditions with parallel builds.
-#
-# Version Management:
-#   The VERSION file in the repo root is the single source of truth.
-#   Version bumps happen in the Dev workflow BEFORE merge to main.
-#   The deploy workflow only reads, validates, and logs the version.
-#   The [skip ci] filter remains as a safety layer for auto-triggers.

+# Nexus Agent Guide
+
+## Scope
+
+These rules apply to the whole Nexus repository. Keep this file concise and
+update it when the build, architecture, or review workflow materially changes.
+
+## Product and architecture
+
+- Nexus is the Noveria operations platform. OpenClaw is integrated through the
+  backend runtime and bridge abstractions; frontend code must not depend on
+  OpenClaw internals.
+- `frontend/` is a Vue 3, TypeScript, Pinia, Vue Router, Vite, and Tailwind 4
+  application.
+- `backend/` is an ASP.NET Core 10 API using Entity Framework Core and
+  PostgreSQL.
+- `backend-tests/` contains the backend test project.
+- `frontend/src/api/` owns HTTP contracts, `frontend/src/stores/` owns client
+  state, and views/components should not duplicate transport logic.
+- Backend changes should preserve the controller -> service -> repository
+  boundaries and keep task mutations behind `ITaskBridgeService` where
+  applicable.
+
+## Required local checks
+
+Frontend:
+
+```powershell
+Set-Location frontend
+pnpm install --frozen-lockfile
+pnpm test
+pnpm build
+```
+
+Backend (requires .NET SDK 10):
+
+```powershell
+dotnet test backend-tests/Nexus.Api.Tests.csproj --configuration Release
+```
+
+Use the versions in CI as the compatibility baseline: .NET 10, Node.js 24, and
+pnpm 10.12.1. Do not silently downgrade target frameworks to match an older
+local SDK.
+
+## Security and review rules
+
+- Default API access to authenticated users or authenticated services. Public
+  endpoints must be explicitly marked and justified.
+- Never treat a caller-controlled identity header as proof of authentication
+  unless a trusted proxy removes and re-establishes it after authenticating the
+  caller.
+- Keep credentials and environment values out of tracked files. Use
+  `.env.template` only for documented placeholders.
+- Changes to authentication, agent commands, task mutation, deployment, or
+  database migrations require focused regression tests.
+- Frontend work must verify the registered route, loading/empty/error states,
+  keyboard semantics, and the 375, 768, 1024, 1440, and 1920 px breakpoints.
+- Do not add navigation entries without a registered route and a working
+  destination.
+
+## Documentation and evidence
+
+- Keep canonical technical documentation in this repository.
+- Put dated audit evidence in `docs/audits/YYYY-MM-DD/`.
+- Update `README.md` when routes, supported versions, deployment behavior, or
+  authentication contracts change.
+- At semantic checkpoints, update the compact Obsidian mirror under
+  `Projects/OpenClaw Mission Control/` after the repository documentation is
+  current. Do not copy large source files or detailed vulnerability mechanics
+  into the Vault.

+## Product target
+
+Nexus is the primary daily control plane for agents, tasks, runs, approvals,
+tools, schedules, knowledge and operational recovery. All agent and model
+execution travels through OpenClaw; OpenAI is the intended primary provider
+configured inside OpenClaw. Nexus does not call OpenAI directly. The browser
+and Nexus domain model stay independent of gateway and provider internals.
+
+The binding product and architecture direction is documented in
+[Agent-First Mission Control](docs/AGENT_FIRST_MISSION_CONTROL.md); the ordered
+feature plan is the [Mission Control Roadmap](docs/MISSION_CONTROL_ROADMAP.md).

-characters. Existing databases are never overwritten by the bootstrap process.
+On an empty database the API creates exactly one owner from `BOOTSTRAP_OWNER_EMAIL`,
+derives the initial display name from that email, and hashes the explicitly configured
+`BOOTSTRAP_OWNER_PASSWORD`. Bootstrap credentials are never written to application logs.
+After first seed the password lives only in PostgreSQL. Existing databases are
+never overwritten by the bootstrap process.
 
 The API is exposed via Traefik reverse-proxy with automatic Let's Encrypt TLS.
 Health checks, rate limiting, and security headers are active.
 
-## Workspace mounts
+## OpenClaw runtime data
 
-The API container mounts agent workspaces from the host for file browsing
-and the config editor. These are mounted under `/mnt/workspace-{agentId}`:
+OpenClaw remains authoritative for its agents, bootstrap files, arbitrary
+workspace files, configuration and cron jobs. Nexus does not copy this state
+into a competing configuration:
 
-| Host path | Container mount |
-|---|---|
-| `/home/projekte_bao/openclaw/data/openclaw/workspace-iris` | `/mnt/workspace-iris` |
-| `/home/projekte_bao/openclaw/data/openclaw/workspace-programmer` | `/mnt/workspace-programmer` |
-| `/home/projekte_bao/openclaw/data/openclaw/workspace-reviewer` | `/mnt/workspace-reviewer` |
-| `/home/projekte_bao/openclaw/data/openclaw/workspace-architekt` | `/mnt/workspace-architekt` |
-| `/home/projekte_bao/openclaw/data/openclaw/workspace-researcher` | `/mnt/workspace-researcher` |
-| `/home/projekte_bao/openclaw/data/openclaw/workspace-executor` | `/mnt/workspace-executor` |
+- agent inventory comes from `agents.list`;
+- supported bootstrap files are read and written through
+  `agents.files.list/get/set`;
+- additional workspace files are browsed read-only through
+  `agents.workspace.list/get`; and
+- OpenClaw configuration is read and patched through
+  `config.schema.lookup`, `config.get` and `config.patch`.
+
+Agent inventory and configuration therefore do not depend on a
+`/mnt/workspace-{agentId}` naming convention. The owner-only Nexus
+Memory/Docs/Incidents read surfaces also resolve their live content through

+UI can show provenance without mounting or inferring a host workspace.

+route.

+### Live orchestration dashboard

+The dashboard prioritizes the live agent topology:
 
-- **IrisPanel** — Agent avatar/greeting, metrics counters (open tasks, blocked,
-  overdue, today), AI suggestions, quick action buttons, and an inline chat box.
-- **OperationsFeed** — Searchable/filterable activity feed with colour-coded
-  status dots and yesterday/today/week grouping.
-- **AgendaPanel** — Daily agenda with checkable items persisted in
-  `localStorage` under key `nexus-agenda-done`. Items are sectioned into
-  "Heute", "Morgen", and "Überfällig".
-- **ActiveInitiatives** — Project initiative cards with progress bars, status
-  badges (healthy/attention/blocked/paused/completed), and last activity timestamps.
-- **RecentlyFinished** — Horizontally scrollable chip list of recently completed items.
+- **AlertBar** — compact active/planning/idle, usage and blocker status.
+- **FlowCanvas** — agent topology, selection, layout reset and model controls.
+- **TaskStrip** — compact focus tasks linked to the task workflow.
+- **IrisChat** — hidden by default and opened from the topbar as a modal.
+- **AgentDetailModal** — live summary, activity and model selection.
+
+### Global agent-first controls
+
+- `Ctrl/Cmd+K` opens a real command palette on every authenticated route.
+- The palette navigates to core surfaces and loaded projects, tasks, agents and
+  sessions. From a task, project or agent it can prefill a correlated durable
+  run.
+- “Ask Iris” sends only bounded route, surface, object-type and object-id
+  context. The backend labels this caller-provided context as untrusted
+  metadata before placing it ahead of the user's message.
+- Command and Iris dialogs are mutually exclusive and support keyboard
+  selection, dismissal and focus restoration.

 ## API endpoints
 
+### MCP Agent Data Plane
+
+Nexus exposes an MCP endpoint at `/mcp` for agent-facing board operations.
+It uses the official `ModelContextProtocol.AspNetCore` SDK with stateless
+streamable HTTP transport. Tools are a thin facade over `ITaskBridgeService`;
+they must not duplicate board business logic. Two additional proposal tools
+use the same durable proposal service as the owner UI and cannot approve or
+provision an agent.
+
+The bridge requires a verified JWT or `X-Nexus-Api-Key`. `X-Agent-Id` is
+accepted only for a service or privileged user principal as an allow-listed
+actor hint; the header is not an authentication credential.
+Secrets stay in server-side runtime configuration and are never embedded in
+frontend code.
+
+Registered tools:
+
+| Tool | Purpose |
+|---|---|
+| `nexus_get_board` | Full task board |
+| `nexus_agent_overview` | Waiting/stale workflow overview |
+| `nexus_get_task` | Single task |
+| `nexus_get_children` | Child tasks for a parent |
+| `nexus_get_activity` | Task activity history |
+| `nexus_create_task` | Create parent/standalone task |
+| `nexus_create_child_task` | Create visible delegation child task |
+| `nexus_update_status` | Update status using the canonical enum only |
+| `nexus_append_activity` | Append checkpoint/activity |
+| `nexus_handoff` | Handoff to a known agent |
+| `nexus_propose_agent` | Create an approval-required proposal; never mutate OpenClaw |
+| `nexus_get_agent_proposal` | Read one durable proposal and provisioning state |
+
+The compatible `/api/bridge` HTTP facade remains available for internal
+diagnostics and transition clients. New agent integrations should use MCP;
+`/api/dashboard` is UI/admin surface, not an agent contract.
+
+### Mission Control Gateway Plane
+
+Nexus keeps the Browser -> Nexus -> OpenClaw boundary: the frontend never talks
+to OpenClaw directly. Read-only Gateway status is exposed through
+`GET /api/dashboard/gateway`; it reports reachability, discovered Gateway
+version and the fail-fast `Integrations:OpenClaw:RequiredVersion` pin. Nexus
+defaults to the verified stable `2026.7.1` contract; upgrades are an explicit
+deployment decision.
+
+The primary browser contract is the authenticated, typed
+`/api/v1/openclaw/*` facade. It uses the Gateway protocol-v4 WebSocket connector,
+reports missing methods separately from missing scopes, and returns explicit
+recovery state instead of converting failures to plausible empty data.

+| `POST` | `/api/v1/openclaw/runs/{id}/resume` | Explicitly reports unsupported until OpenClaw exposes a same-run resume contract |
+
+The compatibility OpenClaw event stream projects connection, run, session,
+tool, approval, artifact and other Gateway events from the bounded connector
+buffer. It accepts `Last-Event-ID`, emits heartbeat and replay-gap events and
+redacts projected payloads. It remains a backend adapter during migration; the
+frontend does not consume raw or projected OpenClaw payloads directly.
+
+The OpenClaw stream above remains the sanitized Runtime projection. Nexus-owned
+workflow changes additionally use `GET /api/v1/events?afterSequence=`. This
+authenticated stream replays the PostgreSQL outbox by global sequence and
+emits content-minimized task, project, proposal, run, activity and notification
+deltas. A cursor older than the retained range returns `resync_required`;
+clients then refresh only affected Query domains. The frontend never consumes
+raw OpenClaw event payloads.
+
+### Agent proposal and provisioning boundary
+
+Manual creation and Iris both create the same durable proposal:
+
+```text
+local form draft -> awaiting_approval -> provisioning
+                                      -> ready | partial | failed | in_doubt
+                 -> rejected
+```
+
+Iris has only `nexus_propose_agent` and `nexus_get_agent_proposal`; neither can
+approve or mutate OpenClaw. After explicit owner approval, the worker rechecks
+local management consent, the official external Client ID, endpoint/TLS trust,
+advertised capability, `operator.admin`, proposal revision and idempotency. It
+derives the workspace from server-side OpenClaw configuration, calls
+`agents.create` at most once, reads the inventory back and only then writes and
+verifies approved standard files. A timeout after possible dispatch becomes
+`in_doubt`; a later retry first reconciles `agents.list`. Post-create file
+failure becomes `partial` and never triggers an automatic agent deletion.
+
+Production provisioning remains disabled while the pinned OpenClaw version
+lacks an officially supported external Nexus or generic operator identity.
+
+Durable runs are stored in PostgreSQL before dispatch together with their
+transition history. They correlate OpenClaw run/session ids with optional
+Nexus task and project ids, actor, correlation id and trace context. Start,
+stop and retry are implemented. Same-run resume is deliberately disabled
+because the pinned Gateway contract does not currently advertise such an RPC.
+
+Nexus does not impersonate OpenClaw's reserved `gateway-client/backend`
+identity. Production attachment remains blocked until the pinned OpenClaw
+release officially supports the external `nexus` client id or another approved
+generic external-operator identity. Once that contract exists, remote or
+container-to-host operation uses Nexus' persisted Ed25519 identity and signed
+challenge response. The exact `PAIRING_REQUIRED` request id is surfaced to the
+owner; a resulting device token stays bound server-side to the normalized
+endpoint, TLS fingerprint and role. The Compose volume
+`nexus-openclaw-device` keeps identity state stable across API restarts and
+must be protected as credential material.
+See [OpenClaw Gateway connection](docs/OPENCLAW_GATEWAY_CONNECTION.md).
+
+Every typed OpenClaw mutation carries a Nexus invocation context with actor,
+correlation id, W3C `traceparent`, and idempotency key. The PostgreSQL claim
+store keeps only metadata and hashed idempotency keys. Because the current
+OpenClaw schemas for `tasks.cancel`, `sessions.abort`, `sessions.patch`,
+`cron.run`, and `approval.resolve` are closed and do not declare an
+`idempotencyKey`, Nexus deduplicates these calls locally instead of sending an
+undocumented field. Schema-confirmed methods such as `chat.send` can opt in to
+wire-level `idempotencyKey` propagation. Active claims and terminal outcomes
+are stored transactionally in PostgreSQL `OperationClaims`; any existing JSONL
+file is treated as an immutable legacy archive and is neither read nor
+appended by the registered store.
+
+Agent activity shown as "Thinking" is redacted before display. Lines containing
+token, password, bearer, authorization, API key or secret markers are replaced
+with a redaction marker. Persisted audit-worthy events should be written as
+short Activity entries, not raw session transcripts.
+
+Dashboard and agent telemetry no longer invent progress, elapsed time, next
+steps, cost or synthetic “Thinking” items. Progress is shown only when a Nexus
+task reports it, token totals only when a Gateway session reports them, and
+unreported values are rendered as unknown. Cost remains unknown until the
+runtime supplies authoritative cost data.
+
+Nexus activity changes arrive as content-minimized domain events and invalidate
+only the affected Query keys. Gateway session history remains read-only
+fallback data: it is fetched on demand, redacted before display and not
+persisted as a long-term raw transcript. Agent "Now" and "Today" summaries are
+deterministic derivations from redacted Nexus activity plus redacted Gateway
+history; Nexus does not call an LLM to summarize this feed.
+
+Config writes and approval actions are owner-only. Agent bootstrap-file writes
+require `expectedHash` and `Idempotency-Key`, re-read before the write, use
+OpenClaw's `agents.files.set`, and verify the stored result afterward. Nexus
+reports only “saved and read back”; it does not claim an unconfirmed runtime
+hot reload. Arbitrary workspace files remain read-only. OpenClaw configuration
+patches use the live schema, `baseHash`, a visible diff and explicit
+`replacePaths`; secret values are never projected to the browser.

+
+### Parent/Child task flow
+
+The Task Board now models OpenClaw delegation as a visible parent/child flow:
+- Iris keeps the parent task `In progress` while delegated work is running.
+- Delegated agent work is represented as visible child tasks linked via `parentTaskId`.
+- Child tasks use the normal visible states (`Backlog`, `In progress`, `Review`, `Blocked`, `Done`) instead of a separate hidden delegation lane.
+- Agent progress hints on parent tasks derive from recent activity and child-task status summaries.
+- Full workflow documentation: [`docs/openclaw-task-board-flow.md`](docs/openclaw-task-board-flow.md)
+
+The initial board request projects every non-Done task and the newest 50 Done
+tasks without entity tracking. Child counts and latest activity are correlated
+inside the projected SQL; the initial path uses at most three statements.
+Further Done pages use an opaque `(UpdatedAt, Id)` keyset cursor and omit the
+active-task query. Task mutations and outbox events reconcile only
+`/api/v1/tasks/{id}/board-card`; a full board reload is reserved for failed
+delta recovery or an explicit stream resync. The supporting PostgreSQL indexes
+are created by
+`20260730224500_AddAgentProvisioningAndBoardIndexes`.
+
+These structural properties do not prove the release performance budgets.
+The 1,000-task/10,000-activity k6 result, SQL plans, statement-count trace and
+browser navigation-to-visible p95 remain separate acceptance evidence; see
+[QA automation](docs/QA_AUTOMATION.md).

 ### CI — Automatic
 
 Every push to `main` triggers `.gitea/workflows/ci.yaml`:
-- **Backend**: .NET restore → build → test
-- **Frontend**: pnpm install → type-check → test → build
+- **Backend**: .NET restore → build → checked-in OpenAPI drift check → test
+- **Frontend**: pnpm install → type-check → generated client drift check →
+  unit test → build → Playwright Chromium E2E
+- **Optional integration**: environment-gated Testcontainers PostgreSQL and
+  Toxiproxy tests
 - **Security**: Scan for hardcoded secrets in source code
 
 CI must never break. If it does, Reviewer fixes.

 Deployment can happen automatically or manually:
 
-#### Auto-Deploy (after successful CI on main)
+#### Auto-Deploy (after successful CI jobs on main)
 
-- Triggered by `workflow_run` after `CI - Build & Test` succeeds on `main`
-- Uses safe defaults: `patch` bump, all services, main ref
-- Skips automatically if the triggering commit contains `[skip ci]` (version-bump commits)
-- The version-bump commit itself uses `[skip ci]` → no infinite CI→Deploy→Bump→CI loops
+- Runs as the final `Deploy Nexus` job in `.gitea/workflows/ci.yaml`
+- Starts only after backend, frontend, and security jobs succeed on `main`
+- Deploys the current `main` version after CI succeeds.
+- This replaces `workflow_run`, which did not create deploy runs in this Gitea 1.26.3 installation.
+- The deploy script reads `VERSION`; it does not mutate Git, bump versions, or create tags
 
 #### Manual Deploy (`workflow_dispatch`)
 
-1. DevOps triggers `Deploy to Production` in Gitea Actions (or Iris auto-approves)
-2. Chooses version bump type: patch (default) / minor / major
-3. Optionally scopes to a single service or specific git ref
-4. Workflow bumps VERSION, creates git tag, builds and deploys
-5. Health check + smoke test verify the deployment
+1. DevOps triggers `Deploy Nexus Manual` in Gitea Actions
+2. Workflow validates `VERSION`, builds and deploys `main`
+3. Health check + smoke test verify the deployment

+The normal test command remains Docker-free:

+dotnet test Nexus.Api.Tests.csproj --configuration Release
+```
+
+Docker-backed tests are discovered but skipped unless explicitly enabled.
+They use `postgres:17-alpine`; the optional network-fault contract additionally
+uses Testcontainers Toxiproxy and a pinned lightweight OpenClaw HTTP stub.
+
+```powershell
+$env:NEXUS_RUN_DOCKER_INTEGRATION_TESTS = "true"
+dotnet test Nexus.Api.Tests.csproj --configuration Release `

+Once opted in, an unavailable Docker daemon is a test failure rather than a
+silent skip. In Gitea Actions, set the repository variable
+`NEXUS_RUN_DOCKER_INTEGRATION_TESTS=true`; optionally set
+`NEXUS_RUN_TOXIPROXY_INTEGRATION_TESTS=true` for the timeout contract. The
