+"""Sanctioned author issue worktree bootstrap for allocated issues (#850).
+
+Bootstraps an allocated author branch, canonical worktree under ``branches/``,
+worktree registration, issue lock, and lease/assignment binding without
+caller-side Git, Bash, or helper scripts.
+
+Features:
+1. Durable phase journal with read-after-write evidence for every phase.
+2. Idempotent replay handling via idempotency keys.
+3. Authoritative expected-base / concurrency-pin validation.
+4. Typed stale-pin refusal without silent rebasing or repointing.
+5. Canonical branches-root enforcement (path MUST be inside branches/).
+6. Preexisting work preservation (dirty tracked/untracked check, foreign ownership refusal).
+7. Compensating recovery limited strictly to artifacts created by this transition.
+8. Satisfiable exact_next_action for MCP scheduled workers.

-
-## 1. Context
-
-The Gitea MCP server is the **control plane** for real issue and PR mutations
-(create, comment, lock, review, merge, reconcile). The same process serves every
-role namespace (`gitea-author`, `gitea-reviewer`, `gitea-merger`,
-`gitea-reconciler`, `gitea-controller`) and holds the in-memory capability-gate
-code loaded at startup.
-
-Restarting that process is destructive to concurrent work:
-
-- It resets every session's identity, preflight, and capability-lease binding.
-- It can interrupt a mutation mid-critical-section (a lock acquire, a review
-  submit, a merge), leaving durable state half-written.
-- Relaunching from the wrong checkout or worktree silently changes which code
-  the control plane runs, defeating master-parity gates (#420 / #615).
-
-Today there is **no durable written policy** stating who may restart MCP, under
-what conditions, that restart is a last resort, and how controller approval,
-automated safety gates, and break-glass interact. Operators and LLM sessions
-therefore invent restart behavior ad hoc, which makes concurrent multi-role work
-unsafe. #630 and #642 need this policy as their backbone.
-
-This ADR defines that policy. It does **not** implement coordinator code or HA
-multi-instance restart (those are later children of #655).
-
-## 2. Decision
-
-### 2.1 v1 decision (recorded)
-
-**Restart authority in v1 is `controller approval + automated safety gates`.**
-
-A restart of the stable control runtime is authorized only when **both** hold:
-
-1. A **controller** role explicitly approves the restart, recording an audit
-   entry (who, why, scope, affected sessions), **and**
-2. The **automated safety gates** pass: a completed drain acknowledgement (no
-   affected session is mid-critical-section) or a declared break-glass incident
-   (§2.5).
-
-Quorum among multiple controllers is **not** required day-one. It is deferred
-unless a later investigation (tracked under #653) proves single-controller
-approval is insufficient. This ADR records the v1 decision so enforcement code
-(#630) has a fixed target; changing it requires a superseding ADR.
-
-### 2.2 Restart is a last resort — the recovery ladder
-
-Restart is the **last** rung. Before any restart, exhaust the narrower
-recoveries, in order:
-
-1. **Reconnect** the IDE/client MCP namespace (transport EOF, `client is
-   closing: EOF`, transient `#584` flap). No process change. See
-   `docs/mcp-namespace-eof-recovery.md`.
-2. **Refresh / rebind** the session workspace: re-run `gitea_whoami`,
-   `gitea_resolve_task_capability`, and pass an explicit validated
-   `worktree_path`. Fixes stale session context without touching the process.
-3. **Scoped restart** of a single misbehaving namespace/service (where the
-   deployment supports per-service restart) rather than the whole control plane.
-4. **Full restart** of the stable control runtime process — operator-owned,
-   controller-approved, drained.
-5. **Host / infrastructure restart** — the broadest action; same authorization
-   as a full restart plus infrastructure ownership.
-
-A session **must** try rungs 1–2 and record why they were insufficient before
-requesting a restart at rung 3 or above. Skipping straight to restart is a
-policy violation.
-
-### 2.3 Authorization matrix
-
-| Role | Reconnect (1) | Refresh/rebind (2) | Scoped restart (3) | Full restart (4) | Host restart (5) |
-|---|---|---|---|---|---|
-| **author** | self | self | request only | **forbidden** | forbidden |
-| **reviewer** | self | self | request only | **forbidden** | forbidden |
-| **merger** | self | self | request only | **forbidden** | forbidden |
-| **reconciler** | self | self | request only | **forbidden** | forbidden |
-| **controller** | self | self | **approve** (+gates) | **approve** (+gates) | request to operator |
-| **operator** | self | self | execute (controller-approved) | execute (controller-approved) | execute (controller-approved) |
-| **admin** | self | self | execute | execute | execute (break-glass) |
-
-Legend: *self* = may perform for its own client session; *request only* = may
-raise a restart request but not authorize or execute it; *approve* = may
-authorize under §2.1 gates; *execute* = may perform the process action after the
-authorization is recorded.
-
-Key invariants:
-
-- **No LLM worker role (author/reviewer/merger/reconciler) may perform or
-  authorize a full or host restart.** They may only reconnect/rebind their own
-  client and file a restart request.
-- **Controller approval authorizes; operator/admin executes.** The approving
-  controller and the executing operator may be the same human, but both the
-  approval and the execution are audited.
-- Privileged process actions (full restart, host restart) are reserved to
-  **operator/admin**, never to an automated worker.
-
-### 2.4 Approved conditions
-
-A restart at rung 3+ is approved only under one of these recorded conditions:
-
-- **No affected sessions:** the control plane has no live session that would be
-  interrupted (verified, not assumed).
-- **Full drain acknowledged:** every affected session has drained
-  (no open critical section — no held mutation lease mid-write) and the drain is
-  acknowledged in the audit record.
-- **Controller + gates:** controller approval plus passing automated safety
-  gates (§2.1), the standard v1 path.
-- **Quorum:** not required in v1; reserved for a future superseding ADR.
-- **Break-glass:** an incident-backed emergency exception (§2.5).
-
-Restart **never** bypasses mutation gates mid-critical-section. Drain before
-restart is mandatory except under break-glass with a declared incident.
-
-### 2.5 Break-glass
-
-Break-glass is a **separate, narrower** authorization path for emergencies where
-the normal drain-and-approve path cannot complete (e.g. the control plane is
-wedged and cannot drain).
-
-Break-glass conditions:
-
-- A declared incident record exists (id, timestamp, declarer) **before** the
-  action.
-- The action is taken by **operator or admin** authority only — never by an LLM
-  worker role, and never unilaterally by an operator with active peers when a
-  controller is reachable.
-- The scope is the minimum necessary rung of the ladder.
-- A **mandatory post-hoc audit** entry is filed: what was restarted, why the
-  normal path was impossible, which sessions were affected, and the incident id.
-
-Break-glass suspends the drain requirement, not the audit requirement.
-
-### 2.6 Explicit prohibitions
-
-- **A unilateral LLM or operator full restart while active peer sessions
-  exist is forbidden.** An LLM worker role must not kill, restart, or relaunch
-  the MCP process; a lone operator must not full-restart over live peer work
-  without controller approval or a break-glass incident.
-- Process-kill recovery is forbidden as a routine tool (#630). This ADR does not
-  introduce a kill path.
-- Ambiguous policy state **denies** restart (§4).
-
-## 3. Security requirements
-
-- Full restart and host restart are **privileged**; only operator/admin execute
-  them, only after a controller approval or break-glass incident is recorded.
-- Break-glass is a distinct authorization path with its own audit mandate; it is
-  never the default and never silent.
-- **Every approval and every restart action is audited** (who approved, who
-  executed, scope, affected sessions, condition, policy version). No restart is
-  authorized without a durable audit entry.
-
-## 4. Failure behavior
-
-**Ambiguous policy → deny restart.** If it cannot be established that a
-restart is authorized under §2 — unknown affected-session state, missing
-controller approval, absent break-glass incident, or an unclassifiable request —
-the safe action is to **refuse** the restart and stop with a recovery report,
-never to restart on assumption.
-
-## 5. Policy IDs (for enforcement code)
-
-Enforcement code — the restart coordinator (a later child of #655), the #630
-contamination guard, and the #642 console restart UX — binds to these stable
-policy identifiers rather than to prose:
-
-| Policy ID | Statement |
-|---|---|
-| `RG-01` | Restart is last resort; rungs 1–2 must be tried and recorded first (§2.2). |
-| `RG-02` | v1 authority = controller approval + automated safety gates (§2.1). |
-| `RG-03` | No LLM worker role performs or authorizes full/host restart (§2.3). |
-| `RG-04` | Full/host restart executed by operator/admin only, post approval (§2.3). |
-| `RG-05` | Drain before restart is mandatory except break-glass with incident (§2.4). |
-| `RG-06` | Break-glass requires a pre-declared incident and post-hoc audit (§2.5). |
-| `RG-07` | Unilateral LLM/operator full restart with active peers is forbidden (§2.6). |
-| `RG-08` | Ambiguous policy state denies restart (§4). |
-
-The `restart-governance/v1` **policy version** field is emitted on future
-restart audit events so approvals can be reconciled against the policy revision
-in force.
-
-## 6. Dogfooding
-
-Gitea-Tools governs its own MCP control plane by this policy. Author, reviewer,
-merger, and reconciler sessions operating on this repository use the recovery
-ladder (§2.2) — reconnect and rebind, never self-restart — and any real restart
-of the Gitea-Tools stable control runtime follows the controller-approval +
-drain path defined here.
-
-## 7. Acceptance and cross-links
-
-This ADR is the authoritative restart-governance policy. It **must** stay
-cross-linked from the safety model and the web-console deployment boundary:
-
-- `docs/safety-model.md` § Process restart governance references this ADR.
-- `docs/webui-deployment.md` references this ADR for restart/reload disposition.
-
-It is linked to its issue lineage — umbrella **#655**, vision **#652**, roadmap
-**#653**, contamination guard **#630**, and console restart UX **#642** — in
-§ Related above.
-
-## 8. Non-goals
-
-- Implementing the restart coordinator or approval state machine (#630, later
-  children of #655).
-- Implementing HA multi-instance restart or quorum machinery.
-- Introducing any process-kill or auto-restart tool; existing auto-restart
-  behavior must be inventoried before any new restart tool is enabled.

-    * ``synced_head_sha`` is a merge commit (two or more parents), i.e. a base
-      merged in — a plain fast-forward of new direct commits is not a sync;
-    * ``prior_head_sha`` is an ancestor of the merge's **first** parent, so the
