fix: hide empty-state copy on queue credential fail-closed (Closes #458)

When fetch_error is set, render only the unavailable banner and an
explicit not-fetched inventory note. Suppress queue tables, pagination
proof, and "No open items." copy that implied a successful empty fetch.

+## Description
+
+[Summary of changes and issue number closed.]
+
+Closes #[Issue Number]
+
+## Checklist
+
+- [ ] I have verified my identity matches the required role.
+- [ ] No secrets, tokens, keychain IDs, or raw service URLs are committed.
+- [ ] All tests pass for touched code.
+- [ ] `git diff --check` is clean.
+
+## Documentation and Wiki
+
+- [ ] Does this change require a wiki update (workflows, tools, profiles, runbooks)?
+- [ ] If yes, has `docs/wiki/` been updated accordingly?
+- [ ] If wiki pages changed, plan the Gitea Wiki sync after merge (`scripts/sync-gitea-wiki.sh`, see Runbooks).
+- [ ] Readiness gate (#224): the Gitea Wiki is populated and current for this repo — verify the repo **Wiki tab**, not `docs/wiki/`. If stale or empty, record the required sync as a follow-up before approval.
+- [ ] If this PR closes a wiki-related issue: closure requires live Gitea Wiki proof links (Wiki Home plus page listing or wiki git log). Markdown in `docs/wiki/`, sync-helper code, or policy docs alone are not sufficient to close a wiki issue.

 ## 1. Boundary and Orchestration
 
 * **GlitchTip-to-Gitea filing is NOT a GlitchTip MCP capability.** The `glitchtip-mcp` boundary remains strictly read-only per ADR-0001.
-* The filing capability lives in an **orchestrator / runbook / release workflow**. It **composes** separate GlitchTip **read** tools (from the `glitchtip-mcp` server) and Gitea **issue** tools (from the `gitea-mcp` server).
+* The filing capability lives in a **library-only orchestrator** in
+  `mcp-control-plane` and is not exposed through `glitchtip-mcp`.
+* The orchestrator composes the real GlitchTip read path with Gitea
+  issue-write tools. It must not use mocked GlitchTip issue data in production
+  filing paths.
 * The orchestrator **must not centralize credentials** into a single server. The GlitchTip MCP holds only GlitchTip tokens, and the Gitea MCP holds only Gitea tokens.
+* If a future MCP surface exposes filing, it must be a separate write-boundary
+  server/profile with explicit Gitea issue-write permission and the same audit
+  gates. It must not be added to the read-only `glitchtip-mcp` surface.
 
 ## 2. Invocation and Safety
 
 * **Explicit invocation only:** There is no automatic, unsupervised filing in phase 1. A human or an explicitly-triggered automation must initiate the workflow.
 * **Dry-run / Preview required:** The orchestrator must present a preview of the drafted Gitea issue (title, body, labels) and obtain explicit confirmation before calling the Gitea mutation tool to file the issue.
-* **Gitea Profile Checks & Audit Logging:** The actual Gitea issue creation relies on `gitea-mcp`, and therefore inherently subjects the mutation to Gitea profile checks and audit logging as standard.
+* **Gitea Profile Checks & Audit Logging:** The actual Gitea issue creation

+* Dedup runs before any Gitea create action.
+* Create/link/skip decisions and audit failure are covered by orchestrator tests.
+* Mutation audit fails closed before any Gitea create, link, or comment mutation.

+- **Workflow Guard:** Before starting reviewer work, task routing checks if the MCP runtime source is mid-merge (by checking for `.git/MERGE_HEAD` or conflict markers). If dirty, it returns `infra_stop` (never `wrong_role_stop` or empty queue) to prevent unsafe mutations.

+## Work Selection Rule for LLMs
+
+Before starting any issue or PR work, acquire or verify a work lease. Do not
+begin coding, reviewing, fixing, branching, committing, pushing, commenting,
+or creating a PR until you prove the target is not already being worked.
+
+Required checks:
+
+1. List open PRs.
+2. Search for PRs linked to the target issue.
+3. Search local and remote branches for the issue number.
+4. Search registered worktrees for the issue branch.
+5. Check dirty worktrees.
+6. Check active leases or recent handoffs.
+7. Check whether the issue was already completed by a merged PR.
+
+If another active LLM/session owns the lease, stop. Allowed responses:
+continue as the lease owner; review the existing PR if reviewer capability
+allows; produce a handoff; request takeover after lease expiry; stop with
+"work already claimed."
+
+Never create a parallel branch or PR for the same issue unless the old branch
+is proven abandoned and the takeover is recorded.
+
+Gitea-Tools lease gates: `gitea_lock_issue` (fail-closed before author
+mutations), `status:in-progress`, and claim comments. `gitea_lock_issue`
+records an `author_issue_work` lease in the issue-lock payload with issue
+number, optional PR number, branch, worktree path, claimant identity/profile,
+created timestamp, expiry timestamp, and last heartbeat timestamp. An active
+same-issue/same-operation lease blocks duplicate work. An expired lease still
+blocks takeover until a recovery review records why the prior work is abandoned,
+completed, or unsafe to continue.
+
+Remote branches matching the issue number are also treated as active work unless
+the recovery review proves the branch is abandoned or superseded. Never delete
+or clean up a branch when it has an active lease, dirty worktree, open PR, or is
+the only copy of unmerged work.
+
+Full portable wording:
+[`skills/llm-project-workflow/SKILL.md`](../skills/llm-project-workflow/SKILL.md).
+
+## Global LLM Worktree Rule
+
+The main project checkout is a stable control checkout. It must stay on the
+configured stable branch: `master`, `main`, or `dev`.
+
+All LLM task work must happen inside the project's `branches/` directory.
+
+Before any mutation, prove:
+
+1. current project root
+2. current working directory
+3. current branch
+4. stable branch for the main checkout
+5. session-owned worktree path under `branches/`
+
+If `cwd` is not inside `branches/`, stop. Do not edit, create, delete, format,
+test-write, commit, merge, rebase, checkout task branches, resolve conflicts,
+or run cleanup.
+
+There are no exceptions for small fixes, docs, tests, cleanup, PR review fixes,
+conflict resolution, or emergencies.
+
+The main checkout may only be used for read-only inspection, fetching,
+stable-branch update after merged PRs, creating `branches/` worktrees, or
+explicit control-checkout repair.
+
+Portable wording: [`skills/llm-project-workflow/SKILL.md`](../skills/llm-project-workflow/SKILL.md).
+
+## Shell Spawn Hard-Stop Rule
+
+Symptom: a shell tool call returns `exit_code: -1` with empty stdout/stderr.
+That is an executor spawn failure, not a command failure — the command never
+ran, and retrying the identical call cannot succeed.
+
+Required behavior (fail closed, issue #258):
+
+1. **Probe once.** On the first spawn failure, run one trivial probe
+   (`echo ok` or `pwd`). If the probe also returns `exit_code: -1`, mark
+   shell unavailable for the session.
+2. **Hard-stop at two.** After two consecutive spawn failures, stop all
+   further shell tool use for the session; never retry the same failing
+   spawn. A hundred retries produce a hundred identical failures (session
+   `019f382e`: 100+ tool calls stalled on a trivial encode-and-commit task).
+3. **Emit a recovery report.** The report must direct the operator to:
+   - restart the session,
+   - kill hung background terminals (a hung test runner holding the
+     executor is a known contributor),
+   - prefer MCP-native paths for remaining mutations (for example
+     `gitea_commit_files` under `gitea.repo.commit`) instead of shell.
+4. **No improvised fallbacks.** Shell unavailability never authorizes
+   WebFetch/browser/manual-encoding workarounds (see #260). No shell means
+   stop-and-report.
+
+Doc-contract tests: `tests/test_shell_spawn_hard_stop_docs.py`.
+
+## Subagent Tool-Budget Guardrails
+
+General-purpose subagents tasked with **deterministic MCP work** (for example a
+single `gitea_commit_files` call) have expanded to 100–122 tool calls,
+WebFetch/Playwright fallbacks, and throwaway helper-script generation instead of
+calling the native MCP tool once (observed during #152 closure, issue #259).
+
+**Default budgets** (fail closed when exceeded):
+
+| Task class | Max tool calls | Max wall time |
+|------------|----------------|---------------|
+| Single-step MCP mutation (`commit_files`, `create_pr`, `lock_issue`) | 15 | 5 minutes |
+| Review / merge queue inspection | 40 | 15 minutes |
+| Exploration / codebase search (non-mutating) | 60 | 20 minutes |
+
+**Required behavior:**
+
+1. **Main session first.** When the active author profile allows
+   `gitea.repo.commit` and `gitea_commit_files` is visible, the main session
+   must call it directly — do not delegate commit authority to a subagent
+   (see #260).
+2. **Native MCP before fallback.** After a shell spawn failure (#258), attempt
+   the native MCP tool once before any alternate path. Shell unavailability
+   never authorizes WebFetch, Playwright, or manual base64 encoding.
+3. **No retry spirals.** Never resume a failed subagent into a larger retry
+   loop or spawn a second subagent for the same deterministic step. Stop and
+   emit a recovery report instead.
+4. **Forbidden detours** when `gitea_commit_files` is available: WebFetch,
+   Playwright/browser automation, manual LLM-generated base64, and ad-hoc

+# MCP Client Registration for External Control Plane Servers
+
+Issue #151 fixes the registration and naming contract for the Jenkins and
+GlitchTip MCP servers that live outside this Gitea MCP runtime.
+
+## Canonical Server Names
+
+Use these exact MCP server names in clients:
+
+| Server name | Boundary | Default capability |
+|---|---|---|
+| `jenkins-mcp` | Jenkins CI inspection (read) | Read-only build/job inspection |
+| `jenkins-write-mcp` | Jenkins build trigger (write) | Gated `jenkins_trigger_build` only |
+| `glitchtip-mcp` | GlitchTip observability inspection | Read-only issue/event inspection |
+
+The write boundary (`jenkins-write-mcp`) is **not** registered by default (#152).
+It exposes a single mutating tool and requires operator approval of a dedicated
+trigger profile before any client config references it.
+
+Historical names such as `jenkins-readonly` and `glitchtip-readonly` are
+descriptive profile labels only. They are not the canonical MCP server names
+unless an operator intentionally creates aliases and documents them.
+
+## Registration Pattern
+
+Register each external server as its own MCP entry. Do not add Jenkins or
+GlitchTip credentials to the Gitea MCP server. Also, do not add Gitea write
+credentials to the GlitchTip server.
+
+```json
+{
+  "mcpServers": {
+    "jenkins-mcp": {
+      "command": "/path/to/mcp-control-plane/venv/bin/python3",
+      "args": ["-m", "jenkins_mcp"],
+      "env": {
+        "JENKINS_MCP_CONFIG": "/path/to/mcp-control-plane/profiles.json",
+        "JENKINS_MCP_PROFILE": "jenkins-readonly"
+      }
+    },
+    "glitchtip-mcp": {
+      "command": "/path/to/mcp-control-plane/venv/bin/python3",
+      "args": ["-m", "glitchtip_mcp"],
+      "env": {
+        "GLITCHTIP_MCP_CONFIG": "/path/to/mcp-control-plane/profiles.json",
+        "GLITCHTIP_MCP_PROFILE": "glitchtip-readonly"
+      }
+    }
+  }
+}
+```
+
+Client-specific wrappers may differ, but the server names, trust boundaries,
+and profile separation must remain the same. After adding or changing either
+entry, reconnect or reload the MCP client before claiming the tools are usable.
+
+## Discoverability Validation
+
+Before using either server in a task, prove the expected tools are visible in
+the client. It is not enough for the config entry to exist.
+
+Expected Jenkins read tools (`jenkins-mcp` only):
+
+- `jenkins_whoami`
+- `jenkins_list_jobs`
+- `jenkins_latest_build`
+- `jenkins_build_status`
+- `jenkins_get_build`
+
+`jenkins_trigger_build` must **not** appear on `jenkins-mcp`. When an operator
+explicitly enables the write boundary, the only expected tool on
+`jenkins-write-mcp` is `jenkins_trigger_build`.
+
+Expected GlitchTip tools:
+
+- `glitchtip_whoami`
+- `glitchtip_list_projects`
+- `glitchtip_list_unresolved`
+- `glitchtip_get_issue`
+- `glitchtip_recent_events`
+- `glitchtip_search`
+
+If a client reports the server as enabled but exposes no usable tools, report
+`SKIPPED: server enabled but no usable tools visible`, then stop. Do not fall
+back to shell commands, raw service APIs, or unrelated MCP servers.
+
+## Boundary Rules
+
+- `jenkins-mcp` read profiles must not expose build trigger tools.
+- Build triggers live on the separate `jenkins-write-mcp` server
+  (`jenkins_mcp.write_server`), not on `jenkins-mcp`.
+- Jenkins build triggers require a dedicated trigger profile with
+  `jenkins.build.trigger` allowed, exact confirmation
+  (`TRIGGER BUILD <job-path>`), and fail-closed mutation audit.
+- Do not register `jenkins-write-mcp` until an operator approves a trigger
+  profile; no shipped profile carries trigger capability by default.
+- `glitchtip-mcp` remains read-only. It must not file or mutate Gitea issues.
+- GlitchTip-to-Gitea filing is a separate library-only orchestrator in
+  `mcp-control-plane` that composes the real GlitchTip read path with Gitea
+  issue-write tools.
+- The filing orchestrator must run GlitchTip/Gitea dedup before any Gitea
+  create action, and its create/link/skip decisions must be covered by tests.
+- The filing orchestrator must fail closed on mutation-audit failure before
+  any Gitea create, link, or comment mutation.
+- If filing is ever MCP-exposed, it must use a separate write-boundary
+  server/profile. It must not be exposed by `glitchtip-mcp`.
+- Gitea credentials never enter Jenkins or GlitchTip runtimes.
+- Jenkins and GlitchTip credentials never enter the Gitea MCP runtime.

 ## 5. Mutation Gating
 Any mutating action (e.g., Gitea issue creation from GlitchTip, or Jenkins builds) must be explicitly allowed by the execution profile.
-- **Jenkins build triggers** exist in jenkins-mcp (landed #4) but require dedicated profile/identity and exact confirmation; not on standard reader profiles. See #56 for boundary correction.
-- **GlitchTip to Gitea issue filing** is documented as a gated, orchestrated workflow (not in glitchtip-mcp), currently partial (mocked, dedup not wired, audit missing). See #57.
+- **Jenkins build triggers** are gated on a separate write boundary
+  (`jenkins-write-mcp` / `jenkins_mcp.write_server`), not on the read-only
+  `jenkins-mcp` surface. Triggers require a dedicated profile with
+  `jenkins.build.trigger`, exact confirmation, and fail-closed mutation audit.
+  No default profile carries trigger capability (#152 / mcp-control-plane #56).
+- **GlitchTip to Gitea issue filing** is a library-only orchestrator in
+  mcp-control-plane (not on `glitchtip-mcp`). See #153 / mcp-control-plane #57.
+
+## 6. Agent Commit Path (no improvised fallbacks)
+
+When an author execution profile allows **`gitea.repo.commit`** and the
+**`gitea_commit_files`** tool is visible, agents must use that MCP path for
+repository commits. Fail closed instead of improvising alternate transports.
+
+Forbidden when MCP commit is available:
+
+- WebFetch or other HTTP calls to external base64/decode services
+- Playwright or browser automation used to work around MCP commit
+- Manual LLM-generated base64 embedded in throwaway scripts as the primary
+  commit transport
+
+If shell helpers are unavailable and MCP commit cannot run, stop with a recovery
+report (restart session, clear hung terminals, use MCP-native commit). See
+[`llm-workflow-runbooks.md`](llm-workflow-runbooks.md) § MCP-native commit path
+(#260) and agent temp artifact cleanup (#261).

+# Internal web UI — local development (#426)
+
+Read-only MVP skeleton for the MCP Control Plane operator console. Gitea,
+MCP capability gates, and `skills/llm-project-workflow/` remain the source of
+truth; this UI only provides route stubs and layout.
+
+## Prerequisites
+
+- Python 3.11+ with project dependencies installed (`pip install -r requirements.txt`)
+- No secrets in repo, config, or client bundle
+
+## Start the server
+
+From the repository root (or an issue worktree):
+
+```bash
+./scripts/run-webui
+```
+
+Or directly:
+
+```bash
+python3 -m webui
+```
+
+Optional environment variables:
+
+| Variable | Default | Purpose |
+|----------|---------|---------|
+| `WEBUI_HOST` | `127.0.0.1` | Bind address (keep local for MVP) |
+| `WEBUI_PORT` | `8765` | Listen port |
+
+## Routes (MVP)
+
+| Path | Description |
+|------|-------------|
+| `/` | Home / operator overview |
+| `/health` | JSON liveness (`status`, `service`, `mode`, `timestamp`) |
+| `/queue` | Live PR and issue queue dashboard (#429) |
+| `/api/queue` | JSON queue export with pagination metadata |
+| `/projects` | Project registry list (#427) |
+| `/projects/{id}` | Project detail + onboarding checklist |

+| `/api/prompts` | JSON prompt export with workflow hashes |
+| `/runtime` | Stub — MCP runtime health (#430) |
+| `/audit` | Stub — report audit paste (#431) |
+| `/worktrees` | Stub — hygiene dashboard (#432) |
+| `/leases` | Stub — lease visibility (#433) |
+
+All routes are GET-only. POST/PUT/PATCH/DELETE return `405` with
+`read-only-mvp`.
+
+## Project registry (#427)
+
+Versioned registry file: `webui/data/projects.registry.json` (schema version `1`).
+
+Override path with `WEBUI_PROJECT_REGISTRY` when operators keep a machine-local
+copy outside git. The registry stores repo identity, remotes, profile names,
+workflow/schema path references, and onboarding checklist steps — never tokens
+or credentials.
+
+Seed entry: **Gitea-Tools** on `https://gitea.prgs.cc` with `prgs-author`,
+`prgs-reviewer`, and `prgs-reconciler` profiles.
+
+## Prompt library (#428)
+
+Prompts are generated at load time from canonical workflow files under
+`skills/llm-project-workflow/workflows/`. SHA-256 hashes are computed from
+`WEBUI_REPO_ROOT` (defaults to the repository root). Prompt bodies are short
+copy/paste starters; canonical workflow files remain the only full policy
+source.
+
+## Live queue dashboard (#429)
+
+`/queue` loads open PRs and issues for the default registry project (seed:
+**Gitea-Tools** on `https://gitea.prgs.cc`) using existing `gitea_auth` read
+credentials. The UI surfaces pagination proof (returned count, pages fetched,
+`has_more`, `inventory_complete`) and classification badges (`claimed`,
+`blocked`, `in-review`, `duplicate`) when evidence exists.
+
+If credentials are missing or the fetch fails, the page shows an explicit error
+instead of an empty queue (fail closed).

+## Project overview
+
+Gitea-Tools provides the Gitea MCP server, execution-profile configuration,
+identity handling, and CLI helpers used across MCP Control Plane workflows.
+It enforces author/reviewer separation, gated review/merge, task-capability
+resolution, and fail-closed safety rails in code.
+
+Canonical long-form docs also live under `docs/` in the repository (for example
+`docs/gitea-execution-profiles.md` and `docs/llm-workflow-runbooks.md`). The
+wiki summarizes operator-facing rules; the repo docs carry implementation detail.

+
+The LLM is not the role — the **MCP execution profile** is the role. Profiles
+bind an authenticated Gitea identity to an allowed operation set.
+
+## Reference profiles (prgs)
+
+### Author / implementer
+
+- **Profile:** `prgs-author`
+- **Typical identity:** `jcwalker3`
+- **Allowed:** branch create/push, PR create, issue comment/create/close, repo commit, read.
+- **Forbidden:** PR approve, merge, request_changes.
+
+### Reviewer / merger
+
+- **Profile:** `prgs-reviewer`
+- **Typical identity:** `sysadmin`
+- **Allowed:** PR review/approve/merge/request_changes, issue comment, read.
+- **Forbidden:** branch push, PR create, repo commit.
+
+## Configuration
+
+Profiles are defined in the canonical JSON config (`GITEA_MCP_CONFIG`, typically
+`~/.config/gitea-tools/profiles.json`). Launchers are thin: they set
+`GITEA_MCP_PROFILE` and point at the config file. Credentials resolve from
+keychain or env references — never inline in client configs.
+
+See `docs/gitea-execution-profiles.md` in the repository for the full model.
+
+## Profile switching
+
+Use separate MCP server namespaces (`gitea-tools` author vs `gitea-reviewer`)
+or distinct launcher entries. Runtime in-place profile switching is disabled by
+default (fail closed).

+Handbook for LLM operators and human developers using the Gitea-Tools MCP server.
+
+## Key rules
+
+1. **Verify identity first** — Run `gitea_whoami` and confirm the active profile before any mutation.
+2. **Resolve task capability** — Call `gitea_resolve_task_capability` for the intended task before gated tools.
+3. **One unit of work per session** — Implement one claimed issue *or* review/merge one PR; do not mix author and reviewer mutations in one session.
+4. **No self-review / no self-merge** — The authenticated Gitea user must not approve or merge a PR they authored.
+5. **Follow the gates** — Prompts express intent; MCP tools enforce safety. Never bypass gates via prompt instructions.
+6. **Global LLM Worktree Rule** — Main checkout stays on `master`/`main`/`dev`; all mutations happen under `branches/`. Prove project root, `cwd`, branch, stable main-checkout branch, and session worktree path before editing. No exceptions.
+
+## Supported Gitea instances
+
+| Remote | Host | Default org/repo |
+|--------|------|------------------|
+| `dadeschools` | `gitea.dadeschools.net` | `Contractor / Timesheet` |
+| `prgs` | `gitea.prgs.cc` | `Scaled-Tech-Consulting / Timesheet` |
+
+Always pass `remote` explicitly on tool calls. The server default is `dadeschools`; forgetting `remote` on a `prgs` task hits the wrong host.
+
+## New session checklist
+
+1. `gitea_whoami` — confirm authenticated user and profile.
+2. `gitea_get_runtime_context` — allowed/forbidden operations for this session.
+3. `gitea_resolve_task_capability` — prove the session may perform the planned task.
+4. For reviewer work: dry-run validation (`gitea_dry_run_pr_review`) before live review mutations.

+
+1. **Closure prevention** — No wiki issue may close on markdown/helper work alone.
+   Closing requires live-Wiki proof: Wiki Home link plus page listing or wiki git log.
+2. **Reviewer checklist** — PR template requires verifying the repo **Wiki tab**.
+3. **Publication authority** — `--push` requires exact `GITEA_WIKI_SYNC_CONFIRM` phrase.
+4. **Per-repo status** — Update [Repositories Map](Repositories.md) when published.

+## Step 1: Review queue first (reviewer profile)
+
+1. `gitea_resolve_task_capability(task="review_pr")`
+2. List open PRs; pick the oldest eligible PR (not self-authored, mergeable).
+3. Pin head SHA; validate diff scope and run tests locally.
+4. `gitea_mark_final_review_decision` → `gitea_review_pr` / `gitea_submit_pr_review`
+5. `gitea_merge_pr` only with `confirmation="MERGE PR <n>"` and pinned head SHA.
+
+## Step 2: Implement issues (author profile)
+
+0. Work Selection Rule — verify a work lease before any mutations (open PRs,
+   issue-linked PRs, branches, worktrees, dirty worktrees, active leases/
+   handoffs, merged-PR completion). Stop if another session owns the lease.
+   `gitea_lock_issue` records an operation-scoped `author_issue_work` lease
+   with issue, branch, worktree, claimant, created, expiry, and heartbeat
+   fields; active or expired same-operation leases require recovery review
+   before takeover.
+0b. Global LLM Worktree Rule — main checkout on `master`/`main`/`dev` only;
+   mutate only from a `branches/` worktree after proving root, cwd, branch,
+   stable main-checkout branch, and session worktree path (no exceptions).
+1. `gitea_resolve_task_capability` for the author task.
+2. `gitea_lock_issue` before implementation mutations.
+3. Claim with `gitea_mark_issue` / `status:in-progress` label.
+4. Branch, implement, test, push, `gitea_create_pr`.
+5. Release claim when done; never self-review the PR.
+
+## Step 3: Operator follow-ups
+
+Wiki publication, credential provisioning, and cross-repo mirror operations are
+operator-confirmed actions — see [Runbooks](Runbooks.md).

-# LLM Project Workflow
+# LLM Project Workflow Skill
 
-A reusable workflow any LLM can follow to work on any repository safely. Copy
-this `skills/llm-project-workflow/` directory into another project unchanged;
-adapt only the forge-specific names in [Adapting to a project](#adapting-to-a-project).
+This skill is a **router**. Do not perform project work from this file alone.
 
-The core promise: **an LLM never does unsafe or untracked work.** Every change
-is tracked by an issue, isolated in its own worktree, reviewed by a different
-identity, and cleaned up only after a real merge.
+Before any project mutation, identify the task mode and load the matching
+workflow file.
+
+## Workflow modes
+
+| Task mode | Workflow | Final report schema |
+|-----------|----------|---------------------|
+| PR review / approval / merge | [`workflows/review-merge-pr.md`](workflows/review-merge-pr.md) | [`schemas/review-merge-final-report.md`](schemas/review-merge-final-report.md) |
+| Reconcile already-landed open PRs | [`workflows/reconcile-landed-pr.md`](workflows/reconcile-landed-pr.md) | [`schemas/reconcile-landed-final-report.md`](schemas/reconcile-landed-final-report.md) |
+| Create or update Gitea issues | [`workflows/create-issue.md`](workflows/create-issue.md) | [`schemas/create-issue-final-report.md`](schemas/create-issue-final-report.md) |
+| Work on an assigned issue / author code | [`workflows/work-issue.md`](workflows/work-issue.md) | [`schemas/work-issue-final-report.md`](schemas/work-issue-final-report.md) |
+| PR-only queue cleanup (one canonical review per PR) | [`workflows/pr-queue-cleanup.md`](workflows/pr-queue-cleanup.md) | [`schemas/pr-queue-cleanup-final-report.md`](schemas/pr-queue-cleanup-final-report.md) |
+
+## Universal rules
+
+- Prove identity, active profile, runtime context, and **exact** capability before
+  mutation.
+- A nearby capability does not count.
+- Do not self-review or self-merge.
+- Do not mix modes in one run.
+- If the required workflow cannot be loaded, stop and produce a recovery handoff
+  only.
+- Final report must use the schema for the loaded workflow.
+- If a task requires a different mode, stop and produce a handoff for the
+  correct workflow.
+
+## Mode isolation
+
+A run that starts in `review-merge-pr` mode may not create process issues,
+implement fixes, or edit source files.
+
+A run that starts in `reconcile-landed-pr` mode may not approve, request
+changes, merge, implement fixes, or create normal issues.
+
+A run that starts in `create-issue` mode may not review, approve, request
+changes, merge, implement fixes, create branches, commit, push, or create PRs.
+
+A run that starts in `work-issue` mode may not review, approve, request changes,
+merge, close PRs, or act as reviewer.
+
+A run that starts in `pr-queue-cleanup` mode may not claim issues, create
+branches, edit implementation files, file new issues, or review a second PR
+after any terminal review mutation.
+
+If the task requires a different mode, stop and produce a handoff for the
+correct workflow.

-- **Landed**: Equivalent content is present on remote `master`, but PR metadata may not say merged.
+- **Landed**: Equivalent content is present on remote `master`, but PR metadata
+  may not say merged.
 - **Closed-not-merged**: PR state is closed and `merged=false`.
-- **Reconciled**: A human/LLM verified whether closed-not-merged content landed, partially landed, or was lost, and repaired issue/label/tracker state.
+- **Reconciled**: Verified whether closed-not-merged or already-landed content
+  is present on the target branch; issue/label/tracker state repaired.
 
-## A. Issue-first rule
+## Work Selection Rule for LLMs
 
-**No repository change without a tracking issue.** This includes creating,
-editing, deleting, or `chmod`-ing files; docs; scripts; commits; pushes; and PRs.
+Before starting any issue or PR work, acquire or verify a work lease. Do not
+begin coding, reviewing, fixing, branching, committing, pushing, commenting, or
+creating a PR until you prove the target is not already being worked.
 
-1. Before any change, confirm a tracking issue exists.
-2. If none exists, create one first (title + problem + scope + acceptance).
-3. Claim it (assign yourself or apply the `status:in-progress` label) and comment
-   that work is starting, including the planned branch name.
-4. **If the issue cannot be created or claimed, stop.** Do not touch files.
+Required checks:
 
-Reading the repo, running read-only status/`git log`, and creating/claiming the
-issue itself are allowed from the orchestration checkout without a prior issue.
+1. List open PRs.
+2. Search for PRs linked to the target issue.
+3. Search local and remote branches for the issue number.
+4. Search registered worktrees for the issue branch.
+5. Check dirty worktrees.
+6. Check active leases or recent handoffs.
+7. Check whether the issue was already completed by a merged PR.
 
-Additional issue-first rules:
+If another active session owns the lease, stop with "work already claimed" or
+produce a handoff.
 
-- Do not implement code without an issue unless explicitly authorized.
-- **Design-only work uses a discussion/RFC issue** — create one or comment on
-  the existing one. Design debates belong on the issue, where other LLMs
-  comment directly. Discussion-only tasks must **not** create branches or PRs;
-  their comments should include recommendations, risks, open questions, and a
-  Controller Handoff (§K; compact format unless high-risk).
-- **If the repo/tracker home for the work is unclear, stop and ask for an
-  owner decision.** Do not create a new repository or a new tracker unless
-  explicitly approved by the owner.
+For Gitea-Tools: `gitea_lock_issue` is the fail-closed lease gate before author
+mutations; `status:in-progress` and claim comments are supporting lease signals.
 
-## B. Isolated worktree rule
+## Global LLM Worktree Rule
 
-**Never implement or review in the main checkout.** The main checkout is for
-orchestration and status only (issue creation, `git status`, creating worktrees).
+The main project checkout is a stable control checkout on `master`, `main`, or
+`dev`. All LLM task work must happen inside the project's `branches/` directory.
 
-- Each issue gets its own branch worktree under an ignored `branches/` directory.
-- Review work uses a **separate** review worktree, never the author's folder.
-- Dirty work in one branch folder must not block starting another issue.
-- No LLM may edit another issue's worktree unless explicitly assigned to it.
-- Branch folders are removed only after the PR is merged/closed **and** cleanup
-  is explicitly part of the task.
+If `cwd` is not inside `branches/`, stop before any file edit, test write,
+commit, merge, rebase, or cleanup. The main checkout is orchestration-only.
 
-Every implementation branch **must include its issue number** so it is
-traceable end to end: **issue → branch → worktree folder → PR → cleanup.**
+## Shell Spawn Hard-Stop Rule
 
-Allowed implementation patterns:
+`exit_code: -1` with empty stdout/stderr means the shell failed to spawn — not a
+command failure. After two consecutive spawn failures, hard-stop shell use for
+the session and emit a recovery report (#258).
 
-- `fix/issue-123-short-description`
-- `feat/issue-123-short-description`
-- `docs/issue-123-short-description`
-- `chore/issue-123-short-description`
+## Isolated worktree naming
 
-Review-only branches:
+Implementation: `(fix|feat|docs|chore)/issue-<number>-<short-description>`
 
-- `review/pr-456-short-description`
+Review: `review/pr-<number>-<short-description>`
 
-Use a filesystem-safe folder under `branches/` by replacing slashes with
-hyphens, for example `branches/fix-issue-123-short-description`.
+## Subagent Tool-Budget Guardrails
 
-`scripts/worktree-start` **enforces** this: it rejects an implementation branch
-that does not match `(fix|feat|docs|chore)/issue-<number>-…` (or a
-`review/pr-<number>-…` branch), unless `--allow-unlinked` is passed. Traceability
-is maintained by:
+General-purpose subagents on **single-step MCP tasks** (for example
+`gitea_commit_files`) must not expand into 100+ tool-call retry spirals with
+WebFetch/Playwright/manual-encoding fallbacks (issue #259).
 
-- the branch name (contains the issue number),
-- a claim comment on the issue, e.g.
-  `Claimed. Branch: fix/issue-123-short-description. Worktree: branches/fix-issue-123-short-description.`,
-- the PR body — `Closes #123` or `Fixes #123` when the PR should close the issue
-  (do NOT use `Implements #123` or `Refs #123` to close, as Gitea will not auto-close),
-- cleanup after merge — remove the remote branch, local branch, and the issue
-  worktree folder, and drop `status:in-progress`.
+Default budgets (stop when exceeded):
 
-For projects using `Gitea-Tools` helpers:
+- **Single-step MCP mutation** (`commit_files`, `create_pr`, `lock_issue`):
+  15 tool calls, 5 minutes wall time.
+- **Review / merge queue inspection**: 40 tool calls, 15 minutes.
+- **Non-mutating exploration**: 60 tool calls, 20 minutes.
 
-```bash
-scripts/worktree-start fix/issue-123-example      # → branches/fix-issue-123-example
-scripts/worktree-review fix/issue-123-example     # → branches/review-fix-issue-123-example (detached)
-scripts/worktree-clean  --delete-branch fix/issue-123-example
-```
+Rules:
 
-Manual equivalent:
+1. When the main session has `gitea.repo.commit`, call `gitea_commit_files`
+   directly — do not delegate commit to a subagent (#260).
+2. After shell spawn failure (#258), attempt the native MCP tool once before
+   any fallback; shell unavailability never authorizes WebFetch/Playwright/
+   manual base64.
+3. Never resume a failed subagent into a larger retry loop or spawn a second
+   subagent for the same deterministic step — stop and report.
+4. When `gitea_commit_files` is available, forbid WebFetch, Playwright,
+   manual encoding, and ad-hoc `_encode_*` / `_emit_*` helpers in the repo.
 
-```bash
-git fetch <remote> --prune
-git worktree add -b fix/issue-123-example branches/fix-issue-123-example <remote>/master
-cd branches/fix-issue-123-example
-```
+Worktree folder: branch with `/` replaced by `-` under `branches/`.
 
-`venv/` and similar are not copied into new worktrees — run checks with a known
-interpreter path, or create a venv inside the branch folder.
+Helpers: `scripts/worktree-start`, `scripts/worktree-review`,
+`scripts/worktree-clean`.
 
-## C. Identity and profile safety
+## Identity and profile safety
 
-- Use canonical execution profiles where available; the profile is the role, not the LLM. A task selects a profile; a profile is not permanently assigned.
-- **Author and reviewer identities must be distinct.**
-- Never place raw tokens/passwords in an LLM/MCP client config. Reference secrets by keychain id or environment variable name only. Prefer a single canonical config file selected by two env vars, e.g.:
-  - `GITEA_MCP_CONFIG` — path to the canonical profiles file
-  - `GITEA_MCP_PROFILE` — the profile to activate
-- **Dual-Profile MCP Launcher Pattern (Recommended):** To avoid relaunch bottlenecks and PR-author deadlocks, register multiple instances of the same MCP server in the client's configuration simultaneously (e.g., `gitea-author` and `gitea-reviewer`), each pointing to its respective `GITEA_MCP_PROFILE`.
-  - Tool calls become namespace-scoped: `mcp__gitea-author__*` and `mcp__gitea-reviewer__*`.
-  - **Trust Model:** Separate tokens remain separate. Profile gates enforce allowed operations, `whoami` is still checked, and self-review/self-merge prevention remains mandatory. This pattern is for convenience and does not bypass security gates.
-  - **Deadlock Warning:** Reviewer/merge identities must not be used to create PRs, as this makes the reviewer the PR author in Gitea and blocks independent review. PRs should normally be created by the author/work identity, keeping the reviewer identity available for reviews.
-  - **Fallback:** If a dual-server launcher is not available in the client, relaunch or restart the client with the correct profile environment variable before claiming work.
-- **If the authenticated user equals the PR author, stop** — no self-review, no self-merge.
+- Author and reviewer identities must be distinct.
+- Never place raw tokens in LLM/MCP config.
+- Use `gitea_whoami` and `gitea_resolve_task_capability` before mutating.

-
-## E. Start-work workflow
-
-1. Verify the orchestration checkout (right repo, clean tree).
-2. Fetch/prune: `git fetch <remote> --prune`.
-3. Confirm local `master` equals remote `master` (`git rev-list --left-right --count <remote>/master...master` → `0	0`).
-4. Create/claim the issue (§A).
-5. Create the isolated worktree (§B) from latest remote `master`.
-6. Implement the narrow scope only — no unrelated refactors or formatting churn.
-7. Add/update focused tests when behavior changes.
-8. Run the checks (tests, compile/lint, `git diff --check`, secret scan).
-   Record the branch name and `HEAD` SHA at validation time — the drift
-   check in step 9 compares against exactly this state.
-9. **Branch proof before commit (#177):** prove and state, immediately
-   before staging/committing (`author_proofs.verify_branch_for_commit`,
-   `author_proofs.detect_branch_drift`):
-   - current branch (`git branch --show-current`) equals the intended
-     feature branch from the issue claim
-   - current branch is not `master`, `main`, `develop`, `development`, or
-     `dev`
-   - branch and `HEAD` have not changed since validation (step 8) — in a
-     shared checkout another session may switch branches mid-session;
-     treat that as expected and **stop before committing** when detected
-   If any check fails, stop and reconcile; do not commit.
-10. Commit with an issue-linked message.
-11. **Branch proof before push (#177):** prove that the local branch, the
-    push target branch, and the intended issue branch all match, and that
-    none of them is a protected branch
-    (`author_proofs.verify_push_target`). If a commit accidentally landed
-    on a protected branch, do **not** push: report the accident and the
-    exact repair steps (`author_proofs.assess_protected_branch_commit`) —
-    never silently continue after a repair.
-12. Push the branch.
-13. Open a PR to `master`. The final report must include the branch proofs
-    from steps 9 and 11 (`author_proofs.build_commit_push_report`).
-14. **If you are the author, stop before review/merge.**
-15. **Normal issue work must not directly push to `master`.** PR content should be merged through the forge PR merge mechanism.
-16. Direct push to `master` is allowed only as a documented recovery exception. If used, the final report must include:
-    - why the PR merge path could not be used
-    - exact commits pushed
-    - PR metadata state
-    - issue labels/state repaired
-    - whether the PR is closed-not-merged
-
-
-## F. Review workflow
-
-1. Use a separate review worktree (`scripts/worktree-review <branch>`), detached.
-2. Verify your authenticated identity.
-3. Verify the PR author — **you must not be the author.** Self-review
-   contamination must be *evidence-backed* (#173): state the authenticated
-   reviewer identity, the PR author identity, whether this session
-   authored/touched the PR branch, and the evidence source for any
-   "same-session author" claim. If the evidence is missing, report the
-   status as **unknown** — never declare contamination by assumption — and
-   choose another PR or stop (`review_proofs.assess_self_review_contamination`).
-4. Verify the worktree is clean.
-5. **Checkout proof (#173):** before reviewing or validating, prove and
-   state: the selected PR head SHA from Gitea (pinned), the local checkout
-   SHA (`git rev-parse HEAD`), that `HEAD ==` the pinned PR head SHA, and
-   that the diff base is the PR base branch. If `HEAD` does not match the
-   pinned head, **stop before review/merge**
-   (`review_proofs.verify_pinned_head_checkout`).
-6. **Inventory proof (#173 + repo disambiguation hardening):** a blind queue
-   review must prove listing completeness before claiming "only PRs found".
-   Use repo-name disambiguation:
-   - "Gitea-Tools" / "gitea tool" / "MCP Gitea tool" / "gitea MCP tool" /
-     "gitea-tools repo" resolve **only** to `Scaled-Tech-Consulting/Gitea-Tools`.
-   - "mcp-control-plane" resolves only to `Scaled-Tech-Consulting/mcp-control-plane`.
-   - Ambiguous ("open PRs", no explicit repo, "MCP Gitea tooling") → inventory
-     **both** configured repos.
-   Report must state exactly which repo(s) were checked. If only one checked:
-   "Only <repo> was checked. Other configured repos were not checked. This is
-   not a complete queue inventory." Never let a single-repo zero hide PRs in
-   the other.
-   Both configured repos must be reported with state filter, pagination proof,
-   and open-PR count (`review_proofs.assess_inventory_completeness` and
-   `resolve_repos_from_user_reference`).
-7. **Role-boundary proof (#175):** a reviewer queue task must not silently
-   become author implementation. If no eligible PR exists, stop with the
-   queue report. Do not claim issues, create branches, commit, push, or open
-   PRs unless the operator explicitly retasks the run as author work. Mixed
-   reviewer+author namespace use must be reported with a justification, and
-   scratch-only notes are not durable evidence unless posted or committed
-   intentionally (`review_proofs.assess_role_boundary`).
-8. Inspect the full diff; confirm scope matches the linked issue; flag unrelated files.
-9. Run the tests. Validation reporting must include the exact command and
-   exact results: pass/fail, counts of tests passed/skipped/failed, any
-   ignored paths and why they are safe to ignore, and whether the command
-   differs from the repository's canonical validation command. Only claim a
-   validation result after the command has completed and its output has
-   been read (`review_proofs.assess_validation_report`).
-10. **Do not merge if checks fail. Do not merge if the reviewer is the author.**
-11. **#179 A-bar proofs** (all fail closed when missing —
-    `review_proofs.assess_capability_evidence`, `assess_sweep_evidence`,
-    `assess_live_state_recheck`, `assess_role_boundary`):
-    - Capability claims must cite exact `gitea_resolve_task_capability`
-      output (or runtime context); a bare "capability checks passed" is
-      downgraded.
-    - The secret/provenance sweep must state the exact command/script/
-      pattern/named method and the scope scanned.
-    - Immediately before submitting a review verdict (and again before any
-      merge), re-read live PR state and prove: still open, live head ==
-      pinned head, base unchanged, no unresolved blocking review state.
-    - Reviewer runs stay in the reviewer namespace; any author-namespace
-      call requires an explicit justification in the report.
-12. The final report must distinguish (`review_proofs.build_final_report`):
-    identity eligible; PR author different from reviewer; session
-    contamination absent (with evidence); validation performed on the pinned
-    head; capability evidence; sweep verdict; live-state recheck; role
-    boundary; merge performed; issue status verified. If any proof is
-    missing, stop or downgrade the result instead of merging confidently.
-
-## G. Merge / cleanup workflow
-
-Only an eligible (non-author) reviewer merges. Before merging: always verify
-the authenticated identity **and** the PR author; cite exact capability
-evidence for merge_pr (#179); respect runtime profile gates; run independent
-validation (do not trust the author's reported results); perform the **final
-live-state recheck** (#179 — PR still open, live head == pinned head, base
-unchanged, no unresolved blocking review state) immediately before the merge
-mutation; and merge with a **pinned head SHA** and, where supported, the
-**expected changed-file set**, so a moved head or widened diff refuses the
-merge. After a real merge:
-
-1. Confirm remote `master` actually contains the merge commit or expected squashed changes via post-merge file-presence verification (A PR is not done just because `master` moved or is marked "closed". Verify that expected files added/modified in the PR are actually present on `master` using `git pull`, `git log --oneline -- <file>`, or `git merge-base --is-ancestor`; linked issues are closed; `status:in-progress` is removed).
-2. Close/release the issue.
-3. Whenever an issue is closed, check for `status:in-progress`: remove it, or report why it could not be removed.
-4. Do not delete the remote source branch until: PR `merged=true`, or reconciliation confirms content is safely landed, or the issue owner explicitly abandons the work.
-5. Remove the local branch.
-6. Remove the branch worktree folder (`scripts/worktree-clean --delete-branch <branch>`). Branches/worktrees are cleaned only after the above is verified.
-7. Fetch/prune.
-8. Confirm the main checkout is clean and current (`0	0` vs remote).
-9. Final merge/reconciliation reports must include: PR metadata (state, merged flag, merge commit/hash), Git content (remote master hash, expected content present or not), and the exact post-merge verification method used & results.
-
-Never run cleanup before the merge is confirmed on remote `master`.
-
-## H. Fail-closed cases
-
-**Stop and report — take no mutating action — if:**
-
-- No issue exists and one cannot be created.
-- Worktree state is unclear or unexpected.
-- Branch/PR state conflicts with the prompt (e.g. prompt says "merged" but it is not).
-- A PR is closed but not merged (closed with `merged=false`). In this case:
-  - stop normal review/merge
-  - do not delete branches/worktrees
-  - do not start dependent work
-  - run reconciliation
-- Local `master` is ahead of remote unexpectedly.
-- The authenticated user is the PR author (for review/merge).
-- Secrets/tokens appear in the diff.
-- Tests fail.
-- A cleanup step would delete unmerged work.
-
-When in doubt, stop and surface the discrepancy; do not guess or work around a gate.
-
-## I. Recovery patterns
-
-- **Dirty worktree from another issue:** do not touch it. Start your issue in its
-  own new worktree; unrelated dirty work must not block you.
-- **Local `master` ahead of remote unexpectedly:** do not push `master`. Confirm
-  the commits are preserved on a feature branch (local + remote) first, then
-  `git reset --hard <remote>/master` to realign. Never discard commits that are
-  not safely pushed elsewhere.
-- **PR closed but not merged (`merged=false`):** do not merge. Run reconciliation: compare PR content to remote `master` and decide:
-  - **fully landed:** comment that content is present on `master`, remove `status:in-progress`, keep/close issue as appropriate, clean up only after content equivalence is confirmed.
-  - **partially landed:** do not clean up, reopen issue if needed, create corrective issue/PR for missing pieces.
-  - **not landed:** reopen issue if needed, reopen PR or create replacement PR, do not clean up source branch/worktree.
-- **Branch deleted before merge:** if the commits still exist locally (a branch or
-  reflog), re-push them and reopen the PR; otherwise recover via
-  `git fsck --lost-found`. Preserve first, then proceed.
-- **Unauthorized/untracked file created:** do not commit it. Leave pre-existing
-  untracked artifacts (e.g. editor/agent dirs, reports) alone; stage only the
-  files your issue names (`git add <files>`, never blind `git add -A`).
-- **Preserve commits before a reset:** confirm the target commits are reachable
-  from a branch that is pushed to the remote, then reset. Verify with
-  `git branch --contains <sha>` and `git log <remote>/<branch>`.
-
-## J. Prompt snippets
-
-Ready-to-copy templates live in [`templates/`](templates/):
-
-- [`start-issue.md`](templates/start-issue.md) — start a new issue.
-- [`review-pr.md`](templates/review-pr.md) — review a PR.
-- [`merge-pr.md`](templates/merge-pr.md) — merge a PR (eligible reviewer only).
-- [`recover-bad-state.md`](templates/recover-bad-state.md) — recover from bad state.
-- [`reconcile-closed-not-merged-pr.md`](templates/reconcile-closed-not-merged-pr.md) — reconcile a closed-not-merged PR.
-- [`worktree-cleanup.md`](templates/worktree-cleanup.md) — clean up after merge.
-- [`release-tag.md`](templates/release-tag.md) — create a release tag.
-
-## K. Controller Handoff (required, every task)
-
-Every LLM task **must end with a `Controller Handoff`** (exact title) — whether the
-task was implementation, review, merge, issue triage, documentation,
-discussion-only, or blocked planning. It lets a controller LLM understand the
-current state immediately, without rereading the conversation.
-
-The section title must be exactly "Controller Handoff" (or "Controller Handoff Summary" for long form). Reports without it are downgraded (see review_proofs.assess_controller_handoff).
-
-**The compact format is the default.** It is written for controller-LLM
-readability, not as a full human status report. PR bodies still carry the
-full review detail — the handoff never replaces PR documentation.
-
-Compact format (default, canonical field set per issue #182):
-
-```md
 ## Controller Handoff
 
-- Task:
-- Repo:
-- Role:
-- Identity:
-- Issue/PR:
-- Branch/SHA:
-- Files changed:
-- Validation:
-- Mutations:
-- Current status:
-- Blockers:
-- Next:
-- Safety:
-```
+Every task must end with a section titled exactly `Controller Handoff`. Compact
+format canonical field set per issue #182; mode-specific schemas in
+`schemas/*-final-report.md` define required fields. Use the final report schema
+for the loaded workflow mode — not the legacy compact block alone.
+`review_proofs.assess_controller_handoff()` validates presence.
 
-Role-specific fields (append to the compact block):
+## Prompt templates
 
-- review/merge tasks: `Selected PR:`, `Reviewer eligibility:`,
-  `Pinned reviewed head:`, `Review decision:`, `Merge result:`,
-  `Linked issue status:`, `Cleanup status:`
-- author tasks: `Selected issue:`, `Claim/comment status:`,
-  `PR number opened:`, `No review/merge:` (explicit confirmation)
-- queue/inventory tasks: `Repositories checked:`, `Open PR counts:`,
-  `Selected PR or reason none selected:`, `Inventory completeness:`
+Ready-to-copy task prompts live in [`templates/`](templates/):
 
-The section title must be exactly `Controller Handoff`.
-`review_proofs.assess_controller_handoff()` validates this section; reports
-missing it (or missing required fields) are downgraded. The handoff never
-replaces the full report — it is the compact continuation summary at the end,
-and the full report must still carry exact validation results and mutation
-confirmation.
-
-The `Safety:` line is never omitted; it is usually:
-
-```text
-no self-review; no self-merge; no tags; no secrets; no prod
-```
-
-Rules (both formats):
-
-- Never omit the handoff, and never omit the safety confirmations.
-- Never bury blockers in earlier text only — they must appear here.
-- If you opened a PR, state clearly that review is needed.
-- If you reviewed but could not merge, name the exact gate that blocked it.
-- If you only commented on a discussion issue, say no code review is needed
-  but owner/design feedback may be needed.
-- If release state was touched, state exactly which tag/commit changed and why.
-- If blocked (permissions, missing repo, missing second reviewer identity,
-  stale dependency, unclear tracker home): stop and report clearly; **never
-  bypass classifiers, profile gates, missing permissions, or live-consent
-  requirements**; give the owner concrete options.
-
-**Use the long format below instead of the compact one only when the task was
-high-risk or complex** — i.e. when any of these happened:
-
-- a merge, tag, or release
-- failed validation
-- permissions/profile gates blocked work
-- secrets or production access were involved
-- a complicated owner decision
-- multiple repos or cross-issue state
-- the owner explicitly asks for the full format
-
-Long format (high-risk/complex tasks only):
-
-```md
-## Controller Handoff Summary
-
-### Work performed
-
-Briefly state what was done.
-
-### Current state
-
-Include:
-- current repo
-- current branch or master commit
-- issue number(s)
-- PR number(s), if any
-- whether work is complete, blocked, ready for review, or discussion-only
-
-### Files changed
-
-List files changed, or say `None`.
-
-### Validation
-
-List commands run and results, or say `Not applicable — discussion only`.
-
-### Issues encountered
-
-List errors, confusing state, permission/profile problems, stale branches,
-failing tests, missing labels, or blocked decisions.
-
-### Review needed?
-
-Say one of:
-- `No review needed — discussion/comment only`
-- `Review needed — PR is open`
-- `Independent non-author review needed`
-- `Owner decision needed`
-- `Blocked`
-
-### Next recommended action
-
-State exactly what should happen next.
-
-### Safety confirmations
-
-Confirm:
-- no self-review
-- no self-merge
-- no release/tag changes unless explicitly requested
-- no secrets committed
-- no production access used unless explicitly authorized
-```
-
-### Example blocked handoff
-
-```md
-## Example blocked handoff
-
-### Work performed
-
-Audited phase-2 MCP Control Plane planning. Found target repo
-`mcp-control-plane` does not exist. Prepared issue pack but did not file it.
-
-### Current state
-
-- Repo: `Scaled-Tech-Consulting/Gitea-Tools`, unmodified
-- Target repo: `mcp-control-plane`, missing
-- Issues: none open in Gitea-Tools
-- PRs: none open
-- Status: blocked pending owner decision
-
-### Files changed
-
-None.
-
-### Validation
-
-Tracker/repo audit only. No code validation required.
-
-### Issues encountered
-
-Repo creation was denied by permission/classifier because it would be scope
-escalation without live consent.
-
-### Review needed?
-
-Owner decision needed.
-
-### Next recommended action
-
-Owner must choose:
-1. create `Scaled-Tech-Consulting/mcp-control-plane`
-2. authorize repo creation while present
-3. file phase-2 issues in Gitea-Tools instead
-
-### Safety confirmations
-
-- no self-review

 ## Adapting to a project
 
-Replace these project-specific names when copying the skill elsewhere:
-
-| Placeholder | Meaning | Example here |
-|-------------|---------|--------------|
-| `<remote>` | Git remote for the forge | `prgs` |
-| default branch | Integration branch | `master` |
-| profile env vars | Canonical config + profile selectors | `GITEA_MCP_CONFIG`, `GITEA_MCP_PROFILE` |
-| `branches/` | Ignored worktree directory | `branches/` |
-| helper scripts | Worktree helpers | `scripts/worktree-start` / `-review` / `-clean` |
-
-The rules in §A–§K are project-agnostic and should not change.
+| Placeholder | Example here |
+|-------------|--------------|
+| `<remote>` | `prgs` |
+| default branch | `master` |
+| profile env vars | `GITEA_MCP_CONFIG`, `GITEA_MCP_PROFILE` |
+| `branches/` | `branches/` |
+| helpers | `scripts/worktree-start` / `-review` / `-clean` |
 
 ## Versioning And Tagging
 
-Releases follow SemVer: **`vMAJOR.MINOR.PATCH`** (use **`v0.x.y`** while
-unstable). Choose the bump by the largest change since the last tag:
-
-- **PATCH** — bug fixes, docs, tests, wrappers, non-breaking workflow polish.
-- **MINOR** — new tools/helpers/config features; backward-compatible behavior.
-- **MAJOR** — breaking config/schema/API behavior or a changed MCP contract.
-
-Tags must:
-
-- be created **only from `master`** (the exact commit on remote `master`),
-- be created **only after the full test suite passes**,
-- be **annotated** tags (`git tag -a`), never lightweight,
-- include release notes / a changelog summary referencing the merged PRs/issues.
-
-**Never tag** feature branches, dirty worktrees, unreviewed or self-authored
-work, or commits not present on remote `master`.
-
-Additional tag rules:
-
-- Do **not** create, move, delete, or push tags unless explicitly instructed.
-- Tag only **after** the intended PR is merged, and tag only the **verified
-  final master merge commit** (never the PR branch head unless the merge
-  commit is exactly that commit).
-- Always **report the tag target commit** in the final report / handoff.
-
-Release process (see [`templates/release-tag.md`](templates/release-tag.md)):
-
-1. `git fetch <remote> --prune`.
-2. Verify local `master` equals remote `master` (`0	0`) and the tree is clean.
-3. Run the full test suite; stop on any failure.
-4. Inspect merged issues/PRs since the last tag
-   (`git log --oneline <last-tag>..<remote>/master`).
-5. Choose the version bump.
-6. Create the annotated tag on remote `master` with release notes.
-7. Push the tag.
-8. Create/update release notes if the forge supports it.
-
-Where present, `scripts/release-tag` automates this with all gates built in
-(SemVer, fetch/prune, on-master, clean tree, local==remote master, HEAD on
-remote master, no duplicate tag, tests, annotated-only). Safe by default: no
-push without `--push`; `--dry-run` changes nothing; `--skip-tests` must be
-explicit and warns.
+Releases follow SemVer from remote `master` only, after full test suite passes.
+See [`templates/release-tag.md`](templates/release-tag.md) and
+`scripts/release-tag`.

+# Create issue workflow (canonical)
+
+**Task mode:** `create-issue`
+
+This file is the canonical issue-creation workflow for Gitea-Tools. Load it
+before any issue mutation. Final report schema:
+[`schemas/create-issue-final-report.md`](../schemas/create-issue-final-report.md).
+
+**Default task prompt:**
+
+> Create or update Gitea issues in this project only if every identity,
+> capability, duplicate-search, issue-scope, final-report, mutation-ledger,
+> and proof-wording gate passes.
+
+Do not improvise around the gates. Follow project skills, MCP gates, and
+workflow rules exactly.
+
+This is an issue-creation workflow. It is not a reviewer workflow and not an
+implementation workflow.
+
+---
+
+## 0. Load the canonical workflow first
+
+Before starting issue creation or issue update work, check whether the project provides a canonical create-issue workflow through a project skill, runbook, or MCP helper.
+
+If available, load it first and report:
+
+* workflow source
+* workflow version, commit, or hash
+* whether this prompt conflicts with the loaded workflow
+
+If the canonical workflow cannot be loaded and the project requires it, stop and produce a recovery handoff only.
+
+## 1. Mode isolation
+
+This run is `create-issue` mode only.
+
+Do not:
+
+* review PRs
+* approve PRs
+* request changes
+* merge PRs
+* close PRs
+* close issues unless the user explicitly asks and exact close capability is proven
+* implement code
+* edit repo files
+* create branches
+* create commits
+* push branches
+* create PRs
+* run tests unless the canonical workflow explicitly requires validation for issue creation
+* perform reviewer-only actions
+* perform author/coder-only actions
+* perform MCP repair
+
+If the task requires review, merge, issue implementation, or MCP repair mode, stop and produce a handoff for the correct workflow.
+
+Do not mix modes in one run.
+
+## 2. Start with live identity, profile, runtime, and capability checks
+
+Prove:
+
+* authenticated identity
+* active profile
+* repo/project
+* runtime context
+* exact capability for reading/searching issues
+* exact capability for creating issues, if creating issues
+* exact capability for commenting on issues, if commenting on existing issues
+* exact capability for editing issues, if editing existing issues
+* exact capability for applying labels, if applying labels
+* exact capability for assigning issues, if assigning issues
+* exact capability for closing issues, only if explicitly requested
+
+A nearby capability does not count.
+
+Examples:
+
+* `create_issue` does not authorize `issue_comment`
+* `issue_comment` does not authorize `create_issue`
+* `create_pr` does not authorize `create_issue`
+* `review_pr` does not authorize `create_issue`
+* `merge_pr` does not authorize `issue_comment`
+* `gitea.read` does not authorize creating, commenting, editing, labeling, assigning, or closing issues
+
+If exact capability cannot be proven, stop and produce a recovery handoff only.
+
+## 3. Stop immediately on blocked infrastructure
+
+If any of the following appears, stop immediately:
+
+* `infra_stop`
+* MCP reconnect failure
+* stale capability state
+* missing capability
+* workspace mismatch
+* dirty control checkout, if the canonical workflow treats that as blocking
+* broken canonical workflow loading
+* failed required preflight
+* capability resolver warning that says the current state may be unsafe
+* stale or inconsistent runtime context
+
+Do not continue duplicate search, issue creation, issue commenting, issue editing, labeling, assignment, or cleanup.
+
+Produce an executable recovery handoff only.
+
+Blocked recovery handoffs must not include direct issue-create or issue-comment replay commands.
+
+Blocked handoffs must say to rerun the full workflow after the blocker clears.
+
+## 4. Main checkout rule
+
+This workflow should not mutate repo files.
+
+Do not edit files in the main checkout.
+
+Do not create branches.
+
+Do not create commits.
+
+Do not push.
+
+Do not run implementation work.
+
+Do not run reviewer validation.
+
+Reading repository files is allowed only when needed to understand the requested issue and only if the canonical workflow permits it.
+
+If the main checkout is dirty and the project treats dirty control checkout as blocking, stop and produce a recovery handoff.
+
+## 5. No raw MCP repair during issue creation
+
+Do not run `pkill`, kill MCP processes, edit MCP config, restart servers, or perform control-checkout repair during issue creation.
+
+If MCP repair is required, stop issue creation and produce a separate `CONTROL-CHECKOUT REPAIR MODE` handoff.
+
+Do not mix MCP repair mode with create-issue mode.
+
+After repair, rerun the full workflow from the beginning.
+
+## 6. No background task tools
+
+Do not use `schedule`, `manage_task`, background jobs, async waits, delayed task tools, or monitoring tasks during issue creation.
+
+Use direct commands and MCP tools only.
+
+If a required action cannot complete synchronously, stop and produce a recovery handoff.
+
+Do not say “I will check later,” “I will monitor,” or “I will continue in the background.”
+
+## 7. No local Gitea fallback during normal issue creation
+
+During normal issue-creation workflows, do not read Gitea profile secret files.
+
+Do not inspect or open files such as:
+
+* `profiles.json`
+* local token stores
+* credential files
+* local Gitea auth/profile config files
+* `.env` files containing Gitea credentials
+* keychain dumps
+* token helper outputs
+
+Do not run local Gitea helper scripts when MCP tools are available.
+
+Use MCP tools for Gitea operations.
+
+Local fallback is allowed only in explicit recovery mode when MCP is unavailable and identity/profile/capability can be independently proven.
+
+If local fallback is used, report:
+
+* why MCP was unavailable
+* exact identity proof
+* exact profile proof
+* exact repo proof
+* exact capability proof
+* exact local command used
+
+Do not use local fallback to bypass MCP gates.
+
+## 8. Understand the requested issue work
+
+Before searching or creating issues, restate the requested issue-creation task in operational terms.
+
+Identify:
+
+* target repo/project
+* issue topic
+* issue type, if known
+* whether this is a new issue, duplicate check, issue update, or issue-comment task
+* whether the user provided exact title/body text
+* whether acceptance criteria were provided
+* whether multiple issues are requested
+* whether labels, assignees, milestones, or links are requested
+* whether any requested action requires capability beyond issue creation
+
+Do not invent missing requirements.
+
+If the request is ambiguous but safe to proceed, make a reasonable best-effort issue with clear assumptions.
+
+If ambiguity would cause unsafe or wrong mutation, stop and ask for clarification or produce a recovery handoff according to project policy.
+
+## 9. Duplicate search before mutation
+
+Before creating any issue, search open and closed issues for duplicates.
+
+Duplicate search must happen before each issue creation unless a batch search clearly covers all proposed issues.
+
+Search terms must include:
+
+* exact proposed issue title
+* key noun phrase from the problem
+* key workflow/tool name
+* key failure phrase or error phrase
+* likely alternate wording
+* linked PR number, issue number, or file name, if relevant
+
+If the user supplied search terms, use those too.
+
+For each proposed issue, report:
+
+* search terms used
+* matching issue numbers/titles
+* whether each match is open or closed
+* whether any match fully covers the requested issue
+* whether any match partially covers the requested issue
+* whether a new issue is still needed
+
+Do not create a duplicate issue if an existing issue fully covers the problem.
+
+If a duplicate exists and fully covers the problem, stop issue creation for that topic and report the duplicate.
+
+If a duplicate exists but is missing important acceptance criteria, comment on the existing issue only if exact `issue_comment` capability is proven and the user/task authorizes commenting.
+
+If commenting is not authorized, report the existing issue and the missing criteria in the final handoff.
+
+## 10. Issue inventory pagination rule
+
+If listing/searching issues returns paginated results, follow pagination until the tool proves there are no more pages.
+
+Do not assume search results or issue inventory are complete.
+
+Pagination proof must not rely on assumed default API page size.
+
+Search/inventory is complete only if one of the following is proven:
+
+* the MCP response explicitly says there is no next page / `has_more=false` / final page
+* the workflow traversed pages until an empty page or explicit final page was returned
+* the tool response includes total-count or pagination metadata proving all relevant issues were returned
+* the request explicitly set `page` / `limit` / `per_page`, and the response explicitly proves the server honored that page size and did not truncate results
+
+Do not say “duplicate search complete” merely because the result count is less than an assumed default page size.
+
+If pagination metadata is absent and the tool cannot page, report `ISSUE_SEARCH_PAGINATION_UNPROVEN`.
+
+If duplicate search cannot be trusted, do not create the issue unless the canonical workflow explicitly permits best-effort issue creation with that limitation disclosed.
+
+## 11. Issue creation scope rule
+
+Create only issues within the requested scope.
+
+Do not create extra issues just because related problems are noticed.
+
+Do not create process-hardening issues unless the user explicitly requested process-hardening or the current task is explicitly about workflow/tooling gaps.
+
+Do not create implementation issues during reviewer mode.
+
+Do not create reviewer issues during work-on-issue mode.
+
+Do not create issues in a different repository unless the user explicitly asked and exact capability is proven.
+
+If multiple issues are requested, create only the requested issues and only after duplicate search for each one.
+
+If a proposed issue is too broad, split it only if the user requested splitting or the canonical workflow requires issue granularity.
+
+## 12. Issue content quality rule
+
+Every created issue must be actionable.
+
+Include, when applicable:
+
+* title
+* problem statement
+* observed evidence
+* expected behavior
+* required behavior
+* acceptance criteria
+* affected workflow/tool/files
+* safety or security considerations
+* duplicate search summary
+* related issues or PRs
+* non-goals, if useful
+
+Acceptance criteria must be concrete and testable.
+
+Avoid vague issues like:
+
+* “make workflow better”
+* “fix LLM behavior”
+* “improve process”
+* “handle this better”
+
+Instead, describe the exact wall, gate, verifier, test, schema, helper, or prompt change required.
+
+## 13. Issue title rule
+
+Use concise, specific titles.
+
+Good title patterns:
+
+* `Enforce <specific gate>`
+* `Add verifier for <specific report/proof problem>`
+* `Split <large workflow> into <specific components>`
+* `Block <unsafe action> during <workflow mode>`
+* `Require <proof type> before <claim/action>`
+
+Avoid titles that are too broad or emotional.
+
+The title should be unique enough that duplicate search can find it later.
+
+## 14. Issue body rule
+
+Issue body must include the full acceptance criteria.
+
+Do not create placeholder issues.
+
+Do not create issues with only a title unless the user explicitly requested title-only creation.
+
+If the user supplied exact issue body text, preserve it unless it contains unsafe instructions, stale facts, or contradictions.
+
+If edits are needed, make the smallest correction necessary and report the correction.
+
+Do not silently change requested meaning.
+
+## 15. Labels, assignees, and metadata
+
+Apply labels, assignees, milestones, or project fields only if:
+
+* the user requested them, or
+* the canonical workflow requires them, and
+* exact capability is proven.
+
+Do not guess labels if project label policy is unknown.
+
+If labels are useful but capability or policy is unclear, mention recommended labels in the final report instead of applying them.
+
+Do not assign issues to people unless explicitly requested or required by project workflow.
+
+## 16. Comment-on-existing issue rule
+
+Comment on an existing issue only if:
+
+* an existing issue partially covers the requested work, or
+* the user asked to add information to an existing issue, or
+* the canonical workflow requires duplicate consolidation comments, and
+* exact `issue_comment` capability is proven.
+
+Comment must be specific and useful.
+
+Include:
+
+* why the existing issue is relevant
+* what acceptance criteria or evidence should be added
+* whether this avoids creating a duplicate
+
+Do not comment just to say “duplicate found” unless the project workflow requires it.
+
+Do not close duplicate issues unless explicitly requested and exact close capability is proven.
+
+## 17. No hidden mutations
+
+Do not perform unreported mutations.
+
+Every issue creation, issue comment, issue edit, label change, assignment, milestone change, close/reopen action, or external-state change must be reported.
+
+If a tool call is dry-run-only, confirmation-gated, rejected, or no-op, report it separately from performed mutations.
+
+A dry run is not a mutation.
+
+A rejected call is not a performed mutation.
+
+A successful issue creation is an issue mutation.
+
+A successful issue comment is an issue mutation.
+
+A successful label/assignment/milestone update is an issue mutation or external-state mutation.
+
+## 18. Issue creation gate
+
+Before creating each issue, verify:
+
+* identity is still valid
+* active profile is still valid
+* runtime context is still safe
+* exact `create_issue` capability is still valid
+* duplicate search was completed or limitation was explicitly allowed
+* proposed title is not a duplicate
+* proposed body includes actionable acceptance criteria
+* target repo is correct
+* no mode switch has occurred
+
+If any gate fails, do not create the issue.
+
+Produce a recovery handoff or duplicate report.
+
+## 19. Issue commenting gate
+
+Before commenting on an existing issue, verify:
+
+* identity is still valid
+* active profile is still valid
+* runtime context is still safe
+* exact `issue_comment` capability is still valid
+* target issue number is correct
+* comment body is specific and useful
+* comment will not duplicate an existing comment
+* no mode switch has occurred
+
+If any gate fails, do not comment.
+
+Produce a recovery handoff or report the intended comment as a recommendation only.
+
+## 20. Issue edit/update gate
+
+Before editing an existing issue, verify:
+
+* identity is still valid
+* active profile is still valid
+* runtime context is still safe
+* exact edit capability is still valid
+* target issue number is correct
+* update is explicitly requested or required by canonical workflow
+* update does not erase useful existing content
+* no mode switch has occurred
+
+If any gate fails, do not edit.
+
+Prefer commenting over editing unless the user explicitly requested an edit or the canonical workflow requires issue body updates.
+
+## 21. Final report must be precise
+
+Include:
+
+* canonical workflow source/version/hash, if available
+* authenticated identity/profile
+* repo/project
+* runtime context summary
+* exact capability proof summary
+* requested issue-creation task
+* duplicate search terms used
+* duplicate search result
+* pagination/final-page proof for issue search, if applicable
+* issues created, with issue numbers and URLs
+* existing issues commented, with issue numbers and URLs
+* existing issues edited, with issue numbers and URLs
+* issues skipped as duplicates, with issue numbers and titles
+* labels/assignees/milestones applied, if any
+* blockers, if stopped
+* confirmation that no PR review, approval, request-changes, merge, branch, checkout, commit, push, or repo-file mutation was performed
+
+If the report and actual tool/command log disagree, fix the report before final output.
+
+## 22. Final report must distinguish mutation types
+
+Do not use the legacy field `Workspace mutations`.
+
+Use only precise categories:
+
+* File edits by issue creator:
+* Worktree/index mutations:
+* Git ref mutations:
+* MCP/Gitea mutations:
+* Issue mutations:
+* Label/assignment/milestone mutations:
+* External-state mutations:
+* Read-only diagnostics:
+
+Use precise wording:
+
+* `File edits by issue creator: none`
+* `Worktree/index mutations: none`
+* `Git ref mutations: none`
+* `Issue mutations: ...`
+
+If no repo files were edited, say:
+
+`File edits by issue creator: none`
+
+If no branches/worktrees were touched, say:
+
+`Worktree/index mutations: none`
+
+If no git refs were updated, say:
+
+`Git ref mutations: none`
+
+Do not hide issue mutations inside vague `MCP/Gitea mutations`.
+
+## 23. Local artifact and report consistency rule
+
+Do not create local walkthrough, notes, markdown, JSON, or report artifacts during issue-creation runs unless the canonical workflow or operator explicitly requires it.
+
+If any file is edited, created, generated, or written, report it under `File edits by issue creator`.
+
+For each file write, report:
+
+* exact path
+* whether it was inside the repo
+* whether it was tracked or untracked
+* why it was created
+* whether final status was checked after the write
+
+Do not say `File edits by issue creator: none` if any file write occurred.
+
+Do not write files after the final clean-status check unless you rerun and report a new final clean-status check.
+
+Default behavior: do not create local artifacts during issue creation.
+
+## 24. Forbidden final-report claims unless proven
+
+Do not claim:
+
+* `duplicate search complete`
+* `no duplicate found`
+* `issue created`
+* `issue commented`
+* `issue updated`
+* `label applied`
+* `capability proven`
+* `runtime safe`
+* `all gates passed`
+* `no file edits`
+* `no unsafe mutation`
+* `no PR mutation`
+* `no repo mutation`
+* `pagination complete`
+* `final page`
+* `no next page`
+
+unless the corresponding proof is included.
+
+If anything blocks safe issue creation or issue update, stop immediately and produce an executable recovery handoff.
+
+Do not improvise around the gates.
+
+## 25. Proof wording enforcement
+
+The following phrases are forbidden unless directly supported by current-session evidence:
+
+* duplicate search complete
+* no duplicate found
+* issue created
+* issue commented
+* issue updated
+* labels applied
+* capability proven
+* runtime safe
+* all gates passed
+* no file edits
+* no unsafe mutation
+* no PR mutation
+* no repo mutation
+* pagination complete
+* final page
+* no next page
+
+If the proof comes from prior state rather than a command/tool run in the current session, label it as prior proof, not live proof.
+
+If a tool call was rejected, confirmation-gated, dry-run-only, or no-op, report it separately from performed mutations.
+
+## 26. Final self-check before output
+
+Before final output, check the report for contradictions.
+
+Verify:
+
+* if any file was edited, `File edits by issue creator` is not `none`

+# PR-only queue cleanup workflow (canonical)
+
+**Task mode:** `pr-queue-cleanup`
+
+Reviewer-role mode for cleanup periods when the queue holds many open PRs.
+Each run dispatches **exactly one** canonical review for **exactly one** PR,
+then stops after any terminal review mutation. The next PR always requires a
+new run with fresh identity, capability, and inventory proof.
+
+This mode composes with the canonical review workflow: for the selected PR,
+load and follow [`workflows/review-merge-pr.md`](review-merge-pr.md) in full.
+This file adds the cleanup-mode boundaries around that per-PR run; it does
+not replace the review workflow.
+
+## 0. Load the canonical workflow first
+
+Load this file and `workflows/review-merge-pr.md` before any mutation and
+report source, version/commit/hash, and any conflict with the operator
+prompt. If either cannot be loaded, stop and produce a recovery handoff.
+
+## 1. Mode isolation — forbidden actions
+
+PR-only cleanup mode forbids, with no exceptions:
+
+* issue claiming (`claim_issue`, `mark_issue`, `lock_issue`)
+* branch creation or push (`create_branch`, `push_branch`)
+* implementation edits of any kind
+* new issue filing (`create_issue`)
+* PR creation (`create_pr`) and commit tools (`commit_files`)
+* reviewing a second PR after any terminal review mutation
+
+`pr_queue_cleanup.check_cleanup_task_allowed` fails closed on these tasks.
+If author-side work is needed, stop and hand off to `work-issue` mode in a
+separate session.
+
+## 2. Identity, capability, and routing
+
+Route `pr_queue_cleanup` through `gitea_route_task_session` — reviewer role
+required; author sessions receive `wrong_role_stop`. Prove `gitea.pr.review`
+capability before selection. Merge additionally requires `gitea.pr.merge`
+plus the explicit per-PR authorization in §4.
+
+## 3. Inventory and selection
+
+Build the complete open-PR inventory with pagination proof
+(`inventory_complete`, final page, `total_count`) before any selection
+claim. Select exactly one PR according to project queue ordering rules
+(oldest-first unless the operator queue says otherwise), skipping earlier
+PRs only with live per-PR proof. No multi-PR validation and no batch report
+may substitute for per-PR proof.
+
+## 4. Terminal mutation chain
+
+`pr_queue_cleanup.resolve_cleanup_run_state` is the authority:
+
+* After `REQUEST_CHANGES` → the run stops.
+* After `COMMENT` or a proof-backed skip → the run stops.
+* After `APPROVED` → the run may continue **only** to same-PR merge, and only
+  when the operator explicitly authorized merge for that specific PR in this
+  run (`Merge authorized: true`) and every merge gate passes.
+* After merge, or on any merge blocker → the run stops.
+* Any terminal mutation targeting a PR other than the selected PR is a hard
+  stop and must be reported as a violation.
+
+## 5. Fresh run per PR
+
+The next PR requires a new run with fresh identity, capability, inventory,
+and ordering proof. Do not carry pinned SHAs, eligibility classes, or
+validation results across runs.
+
+## 6. Final report
+
+Use the schema in
+[`schemas/pr-queue-cleanup-final-report.md`](../schemas/pr-queue-cleanup-final-report.md).
+The report must include the **Next suggested PR** (from the proven ordering)
+without continuing to it, exactly one **Selected PR**, the single terminal
+decision, pagination proof, and `Issue mutations: none` / `Branch mutations:
+none`. `pr_queue_cleanup.assess_pr_queue_cleanup_report` validates these
+fields and fails closed on batch reviews, missing pagination proof, missing
+next-suggested-PR, unauthorized merges, or any issue/branch mutation.

+
+**Task mode:** `reconcile-landed-pr`
+
+This file is the canonical reconciliation workflow for open PRs whose head SHA
+is already an ancestor of the target branch. Load it before any reconciliation
+mutation. Final report schema:
+[`schemas/reconcile-landed-final-report.md`](../schemas/reconcile-landed-final-report.md).
+
+**Default task prompt:**
+
+> Reconcile already-landed open PRs in this project. Do not review or merge
+> normal PRs. Close or comment only when exact capability is proven.
+
+Do not improvise around the gates. Follow project skills, MCP gates, and
+workflow rules exactly.
+
+This is a reconciliation workflow. It is not a normal PR review/merge workflow.
+
+---
+
+## 0. Load the canonical workflow first
+
+Before starting reconciliation work, check whether the project provides a
+canonical reconcile-landed-PR workflow through a project skill, runbook, or MCP
+helper.
+
+If available, load it first and report:
+
+* workflow source
+* workflow version, commit, or hash
+* whether this prompt conflicts with the loaded workflow
+
+If the canonical workflow cannot be loaded and the project requires it, stop and
+produce a recovery handoff only.
+
+## 1. Mode isolation
+
+This run is `reconcile-landed-pr` mode only.
+
+**Do not review or merge normal PRs.**
+
+Do not:
+
+* approve PRs
+* request changes on PRs
+* merge PRs
+* implement code
+* edit repo files
+* create branches
+* create commits
+* push branches
+* create PRs
+* run normal PR validation as review approval input
+* perform author/coder implementation work
+* perform raw MCP repair
+
+If the task requires review, merge, issue implementation, or MCP repair mode,
+stop and produce a handoff for the correct workflow.
+
+Do not mix modes in one run.
+
+## 2. Start with live identity, profile, runtime, and capability checks
+
+Prove:
+
+* authenticated identity
+* active profile (reconciler or author with close capabilities, as required)
+* repo/project
+* runtime context
+* exact capability for reading/listing PRs and issues
+* exact capability for PR inspect (`gitea.read` / view PR)
+* exact capability for issue inspect
+* exact capability for PR comment, if commenting
+* exact capability for issue comment, if commenting
+* exact capability for PR close, if closing PRs
+* exact capability for issue close, if closing issues
+
+A nearby capability does not count.
+
+Examples:
+
+* `review_pr` does not authorize PR close
+* `merge_pr` does not authorize PR close or issue close
+* `create_issue` does not authorize `issue_comment`
+* `issue_comment` does not authorize PR close
+* `gitea.read` does not authorize close or comment mutations
+
+If exact capability cannot be proven, stop and produce a recovery handoff only.
+
+## 3. Stop immediately on blocked infrastructure
+
+If any of the following appears, stop immediately:
+
+* `infra_stop`
+* MCP reconnect failure
+* stale capability state
+* missing capability
+* workspace mismatch
+* broken canonical workflow loading
+* failed required preflight
+* capability resolver warning that says the current state may be unsafe
+* stale or inconsistent runtime context
+
+Do not continue inventory, ancestry proof, commenting, closing, or cleanup.
+
+Produce an executable recovery handoff only.
+
+Blocked recovery handoffs must not include direct close or comment replay
+commands.
+
+Blocked handoffs must say to rerun the full workflow after the blocker clears.
+
+## 4. Main checkout rule
+
+This workflow should not mutate repo files.
+
+Do not edit files in the main checkout.
+
+Do not create branches, commits, or pushes.
+
+Do not run implementation or reviewer validation worktrees for code edits.
+
+Reading repository files is allowed only when needed to understand
+reconciliation scope and only if this workflow permits it.
+
+## 5. No raw MCP repair during reconciliation
+
+Do not run `pkill`, kill MCP processes, edit MCP config, restart servers, or
+perform control-checkout repair during reconciliation.
+
+If MCP repair is required, stop and produce a separate `CONTROL-CHECKOUT REPAIR
+MODE` handoff.
+
+After repair, rerun the full workflow from the beginning.
+
+## 6. No background task tools
+
+Do not use `schedule`, `manage_task`, background jobs, async waits, delayed task
+tools, or monitoring tasks during reconciliation.
+
+Use direct commands and MCP tools only.
+
+If a required action cannot complete synchronously, stop and produce a recovery
+handoff.
+
+## 7. No local Gitea fallback during normal reconciliation
+
+During normal reconciliation workflows, do not read Gitea profile secret files.
+
+Do not inspect `profiles.json`, local token stores, credential files, `.env`
+Gitea credentials, keychain dumps, or token helper outputs.
+
+Do not run local Gitea helper scripts when MCP tools are available.
+
+Use MCP tools for Gitea operations.
+
+Local fallback is allowed only in explicit recovery mode when MCP is unavailable
+and identity/profile/capability can be independently proven.
+
+## 8. Build a complete live open PR inventory
+
+List open PRs for the target repo according to project policy.
+
+Follow pagination until the tool proves there are no more pages.
+
+Do not assume inventory is complete.
+
+Pagination proof must not rely on assumed default API page size.
+
+Inventory is complete only if one of the following is proven:
+
+* the MCP response explicitly says there is no next page / `has_more=false` /
+  final page
+* the workflow traversed pages until an empty page or explicit final page was
+  returned
+* the tool response includes total-count or pagination metadata proving all
+  relevant PRs were returned
+* the request explicitly set `page` / `limit` / `per_page`, and the response
+  explicitly proves the server honored that page size and did not truncate results
+
+If pagination cannot be proven, report `INVENTORY_PAGINATION_UNPROVEN` and stop
+unless project policy allows best-effort reconciliation with that limitation
+disclosed.
+
+## 9. Already-landed proof
+
+For each candidate PR, prove whether the PR head SHA is already landed on the
+target branch.
+
+**Already-landed proof** must include:
+
+* PR number and title
+* candidate head SHA (full 40-hex)
+* target branch name
+* target branch SHA (full 40-hex) after fetch
+* ancestor proof method (`git merge-base --is-ancestor`, equivalent forge API, or
+  documented project helper)
+* ancestor proof result (true/false)
+* live PR state (open/closed, merged flag)
+
+Do not classify a PR as already-landed without live ancestor proof.
+
+If ancestry cannot be proven, classify as `ANCESTRY_UNPROVEN` and skip close
+mutations.
+
+## 10. Linked issue live verification
+
+If the PR claims to close or link an issue, fetch the linked issue live before
+reporting its status.
+
+If the linked issue was not fetched live in the current session, report:
+
+`Linked issue status: not verified in this session`
+
+Do not claim `issue open`, `issue closed`, or `issue resolved` without live
+proof.
+
+## 11. Reconciliation selection rules
+
+Select PRs eligible for reconciliation:
+
+* open PR state
+* `merged=false` unless project policy says otherwise
+* head SHA is ancestor of target branch (already-landed proof passed)
+* not selected for normal review/merge in this run
+
+Eligibility class for selected PRs: `ALREADY_LANDED_RECONCILE_REQUIRED`
+
+Do not select PRs that fail already-landed proof for normal review/merge
+treatment in this mode.
+
+## 12. Reconciliation comment policy
+
+Post a reconciliation comment only if:
+
+* exact PR-comment or issue-comment capability is proven
+* the comment adds durable evidence (ancestor proof summary, recommended close
+  action, linked issue status)
+* the comment will not duplicate an equivalent recent reconciliation comment
+
+If comment capability is missing, record the intended comment in the final
+handoff only.
+
+## 12A. Partial reconciliation policy (#302)
+
+The durable policy when `close_pr` capability is missing is
+**comment-then-stop** (`resolve_partial_reconciliation_plan` in
+`review_proofs.py` enforces it):
+
+* `close_pr` proven → full reconciliation: close the PR and report the
+  close result (`FULL_RECONCILE_CLOSE_ALLOWED`).
+* `close_pr` missing, `comment_pr` proven → post exactly one
+  reconciliation comment carrying PR head SHA, target branch SHA,
+  ancestor proof, linked issue status, and the required missing
+  capability, then stop for a human or authorized close
+  (`PARTIAL_RECONCILE_COMMENT_THEN_STOP`).
+* `comment_pr` also missing → no Gitea mutation; produce a recovery
+  handoff recording the intended comment and required capabilities
+  (`RECOVERY_HANDOFF_ONLY`).
+* Ancestry not proven → no mutation regardless of capability
+  (`GATE_NOT_PROVEN`).
+
+Final reports must explain why the comment was or was not posted and
+name the missing capability (`assess_partial_reconciliation_report`).
+
+## 13. PR close rules
+
+Close a PR only if:
+
+* already-landed proof passed in this session
+* exact PR-close capability is proven
+* PR is still open at mutation time (live re-fetch)
+* head SHA still matches the proved candidate head SHA
+
+If PR-close capability is missing, produce a recovery handoff with exact PR,
+proof, and required capability. Do not loop forever re-blocking the reviewer
+queue.
+
+## 14. Issue close rules
+
+Close a linked issue only if:
+
+* exact issue-close capability is proven
+* linked issue was fetched live
+* issue resolution is justified by landed content and project policy
+* issue is still open at mutation time
+
+If issue-close capability is missing, report the gap in the handoff.
+
+## 15. Missing capability behavior
+
+If any required mutation capability is missing:
+
+* do not improvise with review/merge tools
+* do not ask the operator to bypass capability gates
+* produce a recovery handoff listing exact missing capabilities
+* include safe next action (profile switch, human close, or dedicated reconciler
+  profile)
+
+## 16. Mutation classification
+
+Use precise mutation categories in the final report:
+
+* File edits by reconciler: (expect `none`)
+* Worktree/index mutations:
+* Git ref mutations: (`git fetch` belongs here, not read-only diagnostics)
+* MCP/Gitea mutations:
+* Reconciliation mutations: (PR comment, issue comment, PR close, issue close)
+* External-state mutations:
+* Read-only diagnostics:
+
+Do not use legacy `Workspace mutations`.
+
+## 17. Identity privacy rule
+
+Report identity as `username / profile` (#305).
+
+Do not disclose personal email in final reports unless explicitly required.
+
+## 18. Precise final report
+
+Include:
+
+* canonical workflow source/version/hash
+* authenticated identity/profile
+* repo/project
+* capability proof summary (separate lines for inspect, comment, PR close,
+  issue close)
+* inventory pagination proof
+* selected PR(s) with already-landed proof
+* linked issue live status
+* mutations performed or blocked
+* missing capabilities
+* confirmation that no normal review, approval, request-changes, or merge was
+  performed
+
+## 19. Local artifact and report consistency rule
+
+Do not create local walkthrough, notes, markdown, JSON, or report artifacts
+during reconciliation unless explicitly required.
+
+If any file is edited, report under `File edits by reconciler`.
+
+Default: no repo file edits.
+
+## 20. Forbidden unsupported claims unless proven
+
+Do not claim:
+
+* `already-landed`
+* `PR closed`
+* `issue closed`
+* `pagination complete`
+* `inventory complete`
+* `all gates passed`
+* `no unsafe mutation`
+
+unless the corresponding proof is included.
+
+## 21. Proof wording enforcement
+
+Forbidden unless supported by current-session evidence:
+
+* pagination complete
+* final page
+* no next page
+* PR closed
+* issue closed
+* all gates passed
+
+If proof comes from prior state, label as prior proof, not live proof.
+
+## 22. Final self-check before output
+
+Verify:
+
+* no normal review/merge mutations occurred
+* `git fetch` is under Git ref mutations if it occurred
+* already-landed proof is present for each selected PR
+* handoff uses reconciliation schema, not author/reviewer merge schema
+* no contradiction between narrative report and controller handoff
+
+## 23. Controller handoff schema
+
+End every run with `Controller Handoff` per
+[`schemas/reconcile-landed-final-report.md`](../schemas/reconcile-landed-final-report.md).
+
+## 24. Stop conditions summary
+
+Stop immediately and produce a recovery handoff if:
+
+* canonical workflow cannot be loaded
+* identity/profile/capability cannot be proven
+* runtime context is blocked
+* `infra_stop` appears
+* inventory pagination cannot be proven and best-effort is not allowed
+* already-landed proof cannot be completed
+* required close capability is missing and mutation was attempted
+* live PR/issue state contradicts proof
+* any report contradiction cannot be resolved
+
+Do not improvise around the gates.

+**Default task prompt:**
+
+> Find the next eligible issue in this project, work on it only if all gates

+
+Do not improvise around the gates. Follow project skills, MCP gates, and
+workflow rules exactly.
+
+This is an author/coder workflow. It is not a reviewer workflow.
+
+---
+
+## 0. Load the canonical workflow first
+
+Before starting issue work, check whether the project provides a canonical work-on-issue workflow through a project skill, runbook, or MCP helper.
+
+If available, load it first and report:
+
+* workflow source
+* workflow version, commit, or hash
+* whether this prompt conflicts with the loaded workflow
+
+If the canonical workflow cannot be loaded and the project requires it, stop and produce a recovery handoff only.
+
+## 1. Mode isolation
+
+This run is `work-issue` mode only.
+
+Do not:
+
+* review PRs
+* approve PRs
+* request changes
+* merge PRs
+* close PRs unless the PR creation workflow explicitly does so through Gitea automation
+* close unrelated issues
+* mutate reviewer state
+* perform reviewer-only actions
+* create process-hardening issues unless explicitly authorized and the workflow switches to issue-creation mode
+
+If the task requires review, merge, issue creation, or MCP repair mode, stop and produce a handoff for the correct workflow.
+
+Do not mix modes in one run.
+
+## 2. Start with live identity, profile, runtime, and capability checks
+
+Prove:
+
+* authenticated identity
+* active author/coder profile
+* repo/project
+* runtime context
+* exact capability for reading issues
+* exact capability for claiming/locking issues, if available
+* exact capability for branch creation, if handled through MCP
+* exact capability for pushing branches, if applicable
+* exact capability for creating PRs
+* exact capability for commenting on issues or PRs, if needed
+
+A nearby capability does not count.
+
+Examples:
+
+* `create_issue` does not authorize `issue_comment`
+* `review_pr` does not authorize `merge_pr`
+* `create_pr` does not authorize `merge_pr`
+* `issue_comment` does not authorize `create_issue`
+* `gitea.read` does not authorize issue claim, PR creation, or branch mutation
+
+If capability cannot be proven, stop and produce a recovery handoff only.
+
+### 2A. Pre-task role routing (#139)
+
+Before issue selection or any mutation, resolve the composite author task:
+
+* `gitea_route_task_session(task_type="work-issue", remote=…)` — must return
+  `route_result: allowed_current_session` and `downstream_allowed: true`
+* `gitea_resolve_task_capability(task="work_issue", remote=…)` — must show
+  `required_role_kind: author` and `allowed_in_current_session: true`
+
+Hyphen (`work-issue`) and underscore (`work_issue`) aliases are equivalent.
+If routing returns `ambiguous_task_stop`, `wrong_role_stop`, or
+`route_to_author_session`, stop and produce a recovery handoff only — do not
+fall back to reviewer tools or guess a different profile.
+
+## 3. Stop immediately on blocked infrastructure
+
+If any of the following appears, stop immediately:
+
+* `infra_stop`
+* MCP reconnect failure
+* stale capability state
+* dirty control checkout
+* dirty task worktree
+* missing capability
+* workspace mismatch
+* stale target branch state
+* broken canonical workflow loading
+* failed required preflight
+* capability resolver warning that says the current state may be unsafe
+* stale or inconsistent runtime context
+
+Do not continue issue selection, claiming, implementation, validation, commit, push, PR creation, cleanup, or handoff mutation.
+
+Produce an executable recovery handoff only.
+
+Blocked recovery handoffs must not include direct commit, push, or PR replay commands.
+
+Blocked handoffs must say to rerun the full workflow after the blocker clears.
+
+## 4. Main checkout rule
+
+The main project checkout must stay on `master`, `main`, or `dev`.
+
+Do not do task work in the main checkout.
+
+Do not edit files in the main checkout.
+
+Do not run tests in the main checkout.
+
+Do not commit from the main checkout.
+
+Do not create PRs from the main checkout.
+
+All task work must happen under the project’s `branches/` directory.
+
+No exceptions for small fixes, docs, tests, cleanup, conflict resolution, emergencies, or “just one file.”
+
+If the main checkout is dirty before selection, stop and produce a recovery handoff.
+
+If the main checkout becomes dirty during the run, stop and produce a recovery handoff unless the change is explicitly allowed by the canonical workflow.
+
+## 5. No raw MCP repair during normal issue work
+
+Do not run `pkill`, kill MCP processes, edit MCP config, restart servers, or perform control-checkout repair during normal issue work.
+
+If MCP repair is required, stop issue work and produce a separate `CONTROL-CHECKOUT REPAIR MODE` handoff.
+
+Do not mix MCP repair mode with work-on-issue mode.
+
+Do not use successful repair as permission to resume the same issue workflow. After repair, rerun the full workflow from the beginning.
+
+## 6. No background task tools
+
+Do not use `schedule`, `manage_task`, background jobs, async waits, delayed task tools, or monitoring tasks during issue work.
+
+Use direct commands and MCP tools only.
+
+If a required action cannot complete synchronously, stop and produce a recovery handoff.
+
+Long synchronous commands, such as a test suite, are allowed only if they are run directly and reported with exact command, working directory, and result.
+
+Do not say “I will check later,” “I will monitor,” or “I will continue in the background.”
+
+## 7. No local Gitea fallback during normal issue work
+
+During normal author/coder workflows, do not read Gitea profile secret files.
+
+Do not inspect or open files such as:
+
+* `profiles.json`
+* local token stores
+* credential files
+* local Gitea auth/profile config files
+* `.env` files containing Gitea credentials
+* keychain dumps
+* token helper outputs
+
+Do not run local Gitea helper scripts when MCP tools are available.
+
+Use MCP tools for Gitea operations.
+
+Local fallback is allowed only in explicit recovery mode when MCP is unavailable and identity/profile/capability can be independently proven.
+
+If local fallback is used, report:
+
+* why MCP was unavailable
+* exact identity proof
+* exact profile proof
+* exact repo proof
+* exact capability proof
+* exact local command used
+
+Do not use local fallback to bypass MCP gates.
+
+## 8. Build a complete live issue inventory
+
+List open issues according to the project’s issue selection policy.
+
+Follow pagination until the tool proves there are no more pages.
+
+Do not assume inventory is complete.
+
+Do not claim `next eligible issue`, `oldest eligible issue`, or complete issue inventory unless pagination is proven.
+
+Pagination proof must not rely on assumed default API page size.
+
+Inventory is complete only if one of the following is proven:
+
+* the MCP response explicitly says there is no next page / `has_more=false` / final page
+* the workflow traversed pages until an empty page or explicit final page was returned
+* the tool response includes total-count or pagination metadata proving all relevant issues were returned
+* the request explicitly set `page` / `limit` / `per_page`, and the response explicitly proves the server honored that page size and did not truncate results
+
+Do not say “inventory complete” merely because the result count is less than an assumed default page size.
+
+For each candidate issue, identify:
+
+* issue number
+* title
+* labels
+* status
+* author/requester, if relevant
+* assignee/owner, if any
+* linked PRs, if any
+* dependency/blocker labels, if any
+* whether it appears already claimed
+* whether it appears already implemented or superseded
+* whether it is eligible under project rules
+
+Final report must include pagination/final-page proof.
+
+## 9. Issue selection rules
+
+State the issue ordering policy before selecting an issue.
+
+If the project uses oldest-first, explicitly sort or reason by issue number or created date.
+
+Do not rely on API response order unless the tool proves that order matches the project policy.
+
+Do not pick:
+
+* already-claimed issues
+* issues assigned to another active worker
+* issues with an open PR already covering the work
+* duplicate issues
+* blocked issues
+* dependency-blocked issues
+* already implemented issues
+* issues outside the current requested scope
+* process-hardening issues unless this run was explicitly started for process-hardening work
+* reviewer-only issues if this is author/coder mode
+
+For every earlier issue skipped, report:
+
+* issue number
+* current status
+* blocking category
+* proof used
+* whether there is an open PR
+* whether there is an active claim
+* reason it is not eligible
+
+If eligibility cannot be proven, classify it as:
+
+`ISSUE_ELIGIBILITY_UNVERIFIED`
+
+Then stop or produce a recovery handoff according to project policy.
+
+Do not select an issue based only on memory from a previous session.
+
+## 10. Linked PR / duplicate active work proof
+
+Before claiming or working on an issue, check whether there is already an open PR, branch, or active claim for that issue.
+
+If an open PR already exists for the issue, do not implement duplicate work.
+
+Classify the issue as:
+
+`OPEN_PR_EXISTS`
+
+and skip it only if project policy allows skipping.
+
+If branch naming or PR title convention links issues to branches, search for matching branches or PRs.
+
+Report:
+
+* issue number
+* linked/open PRs found
+* matching branches found, if checked
+* active claims found
+* duplicate work status
+
+Do not create another branch/PR for the same issue unless the project explicitly allows taking over or updating existing work and exact capability is proven.
+
+## 11. Claim or lock the issue before implementation
+
+Claim/lock the issue before implementation if the project provides a claim/lock mechanism.
+
+If claim/lock requires a Gitea mutation, prove exact capability first.
+
+If claim/lock fails, stop.
+
+Do not implement unclaimed work.
+
+If the claim/lock gates are broken, produce a recovery handoff.
+
+Create a tooling issue only if this run is explicitly authorized to switch to issue-creation mode and exact `create_issue` capability is proven.
+
+Report:
+
+* claim mechanism used
+* claim result
+* claim timestamp, if available
+* issue owner/assignee after claim, if available
+
+## 12. Refresh stable branch before branch/worktree creation
+
+Fetch the stable target branch from the remote before creating a task branch or worktree.
+
+Do not rely on stale local `master`, `main`, or `dev`.
+
+Record the fetched stable branch SHA.
+
+If the stable branch cannot be fetched or verified, stop and produce a recovery handoff.
+
+`git fetch`, `git remote update`, and any command that updates refs must be reported under `Git ref mutations`, not read-only diagnostics.
+
+## 13. Branch and worktree ownership rule
+
+Create a fresh session-owned worktree under `branches/`.
+
+Prefer a branch name that includes the issue number, for example:
+
+`feat/issue-<ISSUE_NUMBER>-short-description`
+
+or:
+
+`fix/issue-<ISSUE_NUMBER>-short-description`
+
+Prefer a worktree path like:
+
+`branches/issue-<ISSUE_NUMBER>-short-description`
+
+Before any file edits, prove:
+
+* project root
+* current working directory
+* main checkout branch
+* stable branch
+* stable branch SHA
+* task branch name
+* session-owned worktree path
+* worktree path is inside `branches/`
+* worktree is not the main checkout
+* clean tracked state
+* clean untracked state
+* worktree HEAD/branch state
+
+Do not reuse an existing worktree unless safe-reuse proof passes.
+
+Safe-reuse proof must include:
+
+* exact worktree path
+* worktree is inside `branches/`
+* worktree is not the main checkout
+* worktree is not owned by another active task/session
+* clean tracked state
+* clean untracked state
+* current branch/head before reset
+* reset target SHA
+* explicit project policy allowing reuse/reset
+
+Do not run `git reset --hard`, `git clean`, checkout, or other destructive commands unless the worktree is session-owned or safe-reuse proof passes.
+
+If safe-reuse proof cannot be produced, create a fresh session-owned worktree.
+
+## 14. Implementation scope rule
+
+Implement only what is required for the selected issue.
+
+Do not perform opportunistic refactors.
+
+Do not fix unrelated tests unless they are required for the selected issue and clearly documented.
+
+Do not modify reviewer workflow files unless the selected issue explicitly requires workflow changes.
+
+Do not modify Gitea profiles, MCP authorization, tokens, secrets, deployment config, production config, or credentials unless the selected issue explicitly requires it and exact capability/proof gates pass.
+
+Do not introduce provenance markers, agent signatures, temporary files, debug dumps, or generated artifacts unless required.
+
+If implementation uncovers a separate issue, note it in the final report or create a follow-up issue only if exact capability is proven and project policy allows it.
+
+## 15. File edit rule
+
+All edits must happen only inside the session-owned issue worktree.
+
+Do not edit files in the main checkout.
+
+Do not edit files in reviewer worktrees.
+
+Do not edit unrelated worktrees.
+
+Track every edited, created, deleted, or generated file.
+
+If any file is edited, created, generated, or written, report it under `File edits by author`.
+
+For each file write, report:
+
+* exact path
+* whether it was inside the repo
+* whether it was tracked or untracked
+* why it was created
+* whether final `git status` was run after the write
+
+Do not say `File edits by author: none` if any file write occurred.
+
+Do not write files after the final clean-status check unless you rerun and report a new final clean-status check.
+
+## 16. Validation rule
+
+Run appropriate validation for the selected issue.
+
+Validation may include:
+
+* targeted tests
+* full test suite
+* compile checks
+* lint checks
+* type checks
+* diff checks
+* secret/provenance checks
+* dangerous artifact checks
+* project-specific validation
+
+If validation cannot run, explain why and include the exact failure.
+
+Do not hide failures.
+
+Do not claim success if tests failed.
+
+Do not skip required validation silently.
+
+Do not bypass MCP gates.
+
+Report every validation command with:
+
+* exact command
+* working directory
+* exit code or pass/fail result
+* summary count if available
+* whether it was targeted, full-suite, compile, lint, diff, secret/provenance, or diagnostic validation
+
+If using bare `pytest`, also report:
+
+* `which pytest`
+* `pytest --version`
+* whether it resolves to the project venv
+
+Prefer the project venv executable when available.
+
+## 17. Baseline comparison rule
+
+Do not run tests in the main checkout.
+
+If the full suite fails and you need to prove failures are pre-existing, create a clean baseline worktree under `branches/`, such as:
+
+`branches/baseline-master-issue-<ISSUE_NUMBER>`
+
+Baseline comparison must include:
+
+* baseline worktree path
+* baseline target SHA
+* task branch SHA
+* exact command run on both worktrees
+* baseline failures
+* task branch failures
+* proof the failure signatures match
+* proof the baseline worktree was clean before and after validation
+* proof the issue worktree was clean before and after validation
+
+Do not claim “same as master” unless the clean baseline worktree proof is included.
+
+Do not claim “full-suite failures are pre-existing” unless baseline proof is complete and the failure signatures match.
+
+If full-suite failures differ or proof is incomplete, do not create a PR unless project policy explicitly allows PR creation with documented validation failures.
+
+## 18. Pre-commit review
+
+Before committing, review the actual diff.
+
+Check:
+
+* correctness
+* tests
+* scope
+* security boundaries
+* workflow rule compliance
+* whether the implementation really satisfies the selected issue
+* unrelated changes
+* dangerous generated artifacts
+* secrets
+* provenance markers
+* temporary agent files
+* debug output
+* formatting-only churn
+* docs/tests consistency
+
+Run:
+
+* `git status`
+* `git diff --stat`
+* `git diff`
+* project-required diff checks
+
+Do not commit if unrelated or unsafe changes are present.
+
+## 19. Commit rules
+
+Commit only from the session-owned issue worktree.
+
+Do not commit from the main checkout.
+
+Commit only after implementation and required validation pass, unless project policy explicitly allows draft PRs with failing validation.
+
+Commit message must reference the issue number.
+
+Preferred format:
+
+`fix: short summary (Closes #<ISSUE_NUMBER>)`
+
+or:
+
+`feat: short summary (Closes #<ISSUE_NUMBER>)`
+
+Before commit, prove:
+
+* worktree path
+* branch name
+* selected issue number
+* staged files
+* diff summary
+* validation status
+
+After commit, record:
+
+* commit SHA
+* commit message
+* changed files
+
+Do not amend, reset, rebase, squash, or force-push unless the project workflow explicitly allows it and the worktree is session-owned.
+
+## 20. Push rules
+
+Push only the session-owned task branch.
+
+Do not push `master`, `main`, `dev`, tags, or unrelated branches.
+
+Before push, prove:
+
+* current branch
+* upstream/remote target
+* commit SHA being pushed
+* selected issue number
+* branch name matches the issue
+
+After push, report:
+
+* remote
+* branch
+* pushed commit SHA
+* push result
+
+If push fails, stop and produce a recovery handoff.
+
+## 21. PR creation rules
+
+Create a PR only if implementation and validation pass, unless project policy explicitly allows draft PRs with documented validation failures.
+
+Do not create a PR if:
+
+* issue was not claimed/locked
+* issue eligibility was unproven
+* duplicate open PR exists
+* task branch does not reference the issue
+* implementation is incomplete
+* validation failed without allowed exception
+* worktree is dirty
+* secrets/provenance/dangerous artifacts are present
+* capability for PR creation is missing
+* runtime context is blocked
+* authenticated identity/profile changed unexpectedly
+
+PR must reference or close the issue.
+
+PR body must include:
+
+* summary
+* linked issue
+* files changed
+* validation commands and results
+* risk
+* exact worktree path
+* branch name
+* commit SHA
+* known limitations, if any
+
+Do not merge your own PR.
+
+Do not approve your own PR.
+
+Do not request changes on your own PR.
+
+After PR creation, fetch or view the PR to verify:
+
+* PR number
+* PR URL
+* PR title
+* base branch
+* head branch
+* linked issue
+* head SHA
+* open status
+
+## 22. Cleanup rules
+
+Clean only session-owned temporary/baseline worktrees if the project workflow explicitly allows cleanup.
+
+Do not delete unrelated branches/worktrees.
+
+Do not delete the task worktree if the project expects it to remain for handoff unless policy says cleanup is allowed after PR creation.
+
+Do not update the main checkout unless the canonical workflow explicitly allows it.
+
+Any cleanup is a mutation and must be reported.
+
+## 23. Recovery handoff rules
+
+If blocked, produce a recovery handoff with:
+
+* exact blocker
+* failed tool/function, if any
+* repo/project
+* selected issue, if one was safely selected
+* eligibility class
+* claim/lock state
+* branch name, if created
+* worktree path, if created
+* stable branch and stable branch SHA, if known
+* files changed, if any
+* validation state
+* commit SHA, if committed
+* PR number/URL, if created
+* exact state reached before stopping
+* safe next action
+* statement that no unsafe mutation was attempted
+
+Blocked handoffs must not include direct commit, push, or PR replay commands.
+
+Blocked handoffs must say to rerun the full workflow after the blocker clears.
+
+## 24. Final report must be precise
+
+Include:
+
+* canonical workflow source/version/hash, if available
+* authenticated identity/profile
+* repo/project
+* capability proof summary
+* issue inventory proof, including pagination/final-page proof
+* issue ordering policy used
+* selected issue number/title
+* eligibility class
+* skipped earlier issues and proof, if any
+* duplicate active work proof
+* claim/lock result
+* stable branch and stable branch SHA
+* branch name
+* worktree path
+* worktree inside `branches/`: true/false
+* worktree branch/HEAD state
+* worktree dirty before implementation: true/false
+* files changed
+* validation commands and results
+* baseline comparison result, if used
+* pre-commit diff review result
+* commit SHA and commit message, if committed
+* push result, if pushed
+* PR number and URL, if created
+* PR verification result, if created
+* cleanup result
+* blockers, if stopped
+* confirmation that the main checkout was not used for task work
+
+If the report and actual tool/command log disagree, fix the report before final output.
+
+## 25. Final report must distinguish mutation types
+
+Do not use the legacy field `Workspace mutations`.
+
+Use only precise categories:
+
+* File edits by author:
+* Worktree/index mutations:
+* Git ref mutations:
+* MCP/Gitea mutations:
+* Issue mutations:
+* Branch mutations:
+* Commit mutations:
+* Push mutations:
+* PR mutations:
+* Cleanup mutations:
+* External-state mutations:
+* Read-only diagnostics:
+
+`git fetch`, `git remote update`, and any command that updates refs must be listed under `Git ref mutations`, not read-only diagnostics.
+
+If `git reset --hard`, checkout, clean, worktree add/remove, merge simulation, merge abort, or similar commands occurred, report them under `Worktree/index mutations`.
+
+Use precise wording:
+
+* `File edits by author: none`
+* `Worktree/index mutations: ...`
+* `Git ref mutations: ...`
+* `MCP/Gitea mutations: ...`
+
+Do not collapse issue, branch, commit, push, PR, cleanup, or external-state mutations into vague wording.
+
+## 26. Forbidden final-report claims unless proven
+
+Do not claim:
+
+* `next eligible issue`
+* `oldest eligible issue`
+* `issue claimed`
+* `no duplicate work`
+* `no open PR`
+* `worktree clean`
+* `validation passed`
+* `same as master`
+* `full-suite failures are pre-existing`
+* `committed`
+* `pushed`
+* `PR created`
+* `issue closed`
+* `main checkout untouched`
+* `no file edits`
+* `no unsafe mutation`
+* `all gates passed`
+* `target branch up to date`
+
+unless the corresponding proof is included.
+
+If anything blocks safe work or PR creation, stop immediately and produce an executable recovery handoff.
+
+Do not improvise around the gates.
+
+## 27. Proof wording enforcement
+
+The following phrases are forbidden unless directly supported by current-session evidence:
+
+* next eligible issue
+* oldest eligible issue
+* inventory complete
+* no duplicate work
+* issue claimed
+* worktree clean
+* validation passed
+* same as master
+* full-suite failures are pre-existing
+* committed
+* pushed
+* PR created
+* issue closed
+* target branch up to date
+* all gates passed
+* no unsafe mutation
+* no file edits
+
+If the proof comes from prior state rather than a command/tool run in the current session, label it as prior proof, not live proof.
+
+If a tool call was rejected, confirmation-gated, dry-run-only, or no-op, report it separately from performed mutations.
+
+## 28. Final self-check before output
+
+Before final output, check the report for contradictions.
+
+Verify:
+
+* if any file was edited, `File edits by author` is not `none`
+* if any worktree was added/removed, `Worktree/index mutations` lists it
+* if any fetch happened, `Git ref mutations` lists it
+* if any issue was claimed/commented/updated, `Issue mutations` lists it
+* if any branch was created, `Branch mutations` lists it
+* if any commit was created, `Commit mutations` lists it
+* if any push occurred, `Push mutations` lists it
+* if any PR was created, `PR mutations` lists it
+* if any cleanup happened, `Cleanup mutations` lists it
+* if any issue/PR external state changed, `External-state mutations` lists it
+* if pagination is claimed complete, final-page proof is present
+* if same-as-master is claimed, baseline proof is complete
+* if selected issue is claimed next eligible, every earlier issue has proof-backed skip reasoning
+* if PR created is claimed, PR verification proof is present
+* if main checkout untouched is claimed, main checkout status proof is present
+
+If any contradiction exists, fix the final report before output.
+
+## 29. Controller handoff schema
+
+End every run with a controller handoff using this schema.
+
+Do not omit fields. Use `none` or `not verified in this session` where appropriate.
+
+Controller Handoff:
+
+* Task:
+* Repo:

+* runtime context is blocked
+* infra stop appears
+* MCP reconnect fails
+* capability state is stale
+* issue inventory pagination cannot be proven

+"""Fail-closed subagent delegation gates (#266).
+
+Subagents can bypass or lose context for worktree, capability, mutation,
+retry, and reporting rules. These helpers make delegation an explicit,
+provable decision instead of a default: deterministic write tasks stay
+inline unless the parent session records why a subagent is needed and
+hands the subagent the full gate context it must operate under.
+
+Like ``author_proofs``/``review_proofs``, the helpers are pure (no git,
+no API calls): the parent workflow gathers the facts and passes them in,
+so the same logic works from prompts, harness assertions, and tests.
+Nothing here weakens the review/merge/permission gates — a delegated
+subagent is subject to the same gates as its parent.
