fix(gate): preserve exact-owner renewal evidence across duplicate rechecks (Closes #945)

An exact-owner lease renewal (#760) is granted the owning-PR duplicate-work
waiver inside gitea_lock_issue, but every later enforcement path rebuilt that
proof from the durable lock through
issue_lock_recovery.recovered_owning_pr_from_lock, which reads only the
dead_session_recovery block. A plain renewal persists its proof under
lease_renewal instead, so the waiver expired with the lock call and the next
author mutation was refused duplicate_commit_prevented with
owning_pr_recovery_exempted: false on the very PR the renewal had just proved.

Add issue_lock_renewal.owning_pr_renewal_from_lock as the renewal mirror of the
recovery rebuild, and resolve both halves through one helper,
_owning_pr_continuation_from_lock, in the same precedence gitea_lock_issue
applies. The three enforcement paths that previously saw only recovery evidence
now share that resolver: the commit/create-PR duplicate recheck, the read-only
duplicate assessor, and the push-ownership prover.

The rebuild re-applies the equality the renewal assessor required (PR head ==
local head == remote head) and additionally binds the record to the claimant the
lock names, so a renewal block cannot be reused under another identity, profile,
or workflow session. Validation of the resulting token against live PR state is
unchanged and still owned solely by
issue_work_duplicate_gate._assess_owning_pr_exemption, so repository, issue, PR,
branch and head binding continue to be enforced in exactly one place.

No public signature, MCP tool schema, refusal shape, or reason code changes.
Dead-session recovery behaviour is untouched.

Tests: tests/test_issue_945_owning_pr_renewal_continuation.py - 49 tests,
8 subtests, all in-memory (no durable branch, worktree, lock, lease or PR).
Against unmodified aab54d48 the suite is 47 failed / 2 passed; the 2 that pass
are the defect-pinning reproductions. Full suite 28F/5574P/6S/1002 subtests at
head vs 28F/5525P/6S/994 at base, with identical failing test id sets.

+
+---
+
+## 1. Context & Problem Statement
+
+The Gitea MCP server operates as the authoritative **control plane** for managing issues, Pull Requests, code mutations, formal reviews, and workflow reconciliations. Under single-process governance ([#656](https://gitea.prgs.cc/Scaled-Tech-Consulting/Gitea-Tools/issues/656)), process restarts are strictly controlled using pre-flight checks, drain phases, and operator approvals.
+
+However, a single-instance control plane inherently presents fundamental constraints:
+
+1. **Downtime during updates:** Even a perfectly executed single-process drain requires a window where incoming client requests must be paused or rejected while the server binary or python environment reloads.
+2. **Single point of failure:** Infrastructure issues, process crashes, or unhandled host-level terminations immediately disconnect active LLM sessions and leave transient workflows incomplete.
+3. **Multi-agent concurrency bottlenecks:** High volumes of concurrent multi-LLM tasks put all lock management, lease allocation, and Gitea API interactions through a single process event loop.
+
+To achieve true zero-disruption operation and seamless rolling deployments without stopping active work, the system requires a high-availability (HA), multi-instance MCP architecture.
+
+---
+
+## 2. Architectural Principles & Non-Goals
+
+### 2.1 Core Architectural Principles
+* **Gitea as Canonical Work SoT:** Gitea remains the ultimate System of Record (SoT) for issue states, pull requests, labels, and audit comments. The MCP control plane does not duplicate domain entities.
+* **Control-Plane DB as Multi-Instance State Substrate:** The control-plane SQLite/durable database ([#613](https://gitea.prgs.cc/Scaled-Tech-Consulting/Gitea-Tools/issues/613)) acts as the single source of truth for workflow leases, session tokens, assignment records, and lock fences across all MCP nodes.
+* **Stateless Worker Nodes:** MCP role server processes (`gitea-author`, `gitea-reviewer`, `gitea-merger`, `gitea-reconciler`, `gitea-controller`) maintain no unique in-memory state; any node can handle any request given a valid session resume token.
+* **Fail-Closed Split-Brain Defense:** In any network partition or quorum loss scenario, nodes must fail closed rather than risk double-mutations or conflicting Gitea states.
+
+### 2.2 Non-Goals
+* **Replacing Gitea:** We do not replace Gitea issue/PR tracking with an independent database.
+* **Immediate Multi-Node Cluster Execution in v1:** This ADR defines the target architecture and phased roadmap; immediate implementation occurs incrementally post-[#655] v1.

+
+### 3.2 Key System Components
+
+#### A. Multiple MCP Instance Cohorts
+* The control plane runs across $N \ge 2$ redundant process nodes.
+* Dual-namespace deployment allows running the old version (Node A) alongside a updated version (Node B) during rolling upgrades.
+
+#### B. Shared Durable Session Storage & Resume Tokens
+* Session context, preflight verification proofs, and capability resolution states are stored in the shared control-plane database.
+* Client requests carry an explicit `session_id` and `resume_token`. If an MCP instance restarts or a request routes to a different instance, the target node validates the token against the database without requiring full session re-initialization.
+
+#### C. Shared Lease Authority & Fencing Counters
+* Workflow leases (`gitea_allocate_next_work`, `gitea_adopt_workflow_lease`) use monotonic fencing tokens (`lease_generation_id`).
+* When Node B acquires or renews a lease, it increments the generation counter. Any delayed or out-of-order write attempt from Node A using an older generation token is rejected by database constraints.
+
+#### D. Leader Election & Coordinated Drain
+* Node clusters elect a primary coordinator node for administrative background tasks (such as stale lease cleanup or incident Watchdogs).
+* During a rolling deployment:
+  1. Node B (new version) is launched and registers as healthy.
+  2. Router directs new session creations to Node B.
+  3. Node A enters `MAINTENANCE_DRAIN` status ([#659](https://gitea.prgs.cc/Scaled-Tech-Consulting/Gitea-Tools/issues/659)), completing in-flight mutations while refusing new tasks.
+  4. Once all active sessions migrate or complete, Node A shuts down cleanly.
+
+#### E. Idempotent Mutations & Failover Safety
+* All state-changing tool executions (PR creation, review submission, merge operations, label changes) carry a deterministic `idempotency_key`.
+* If a network connection flaps or a node fails mid-mutation, the re-issued request with the same `idempotency_key` is recognized by the control-plane substrate, returning the existing recorded result without repeating side effects on Gitea.
+
+#### F. Schema Version Compatibility
+* Database migrations follow non-breaking additive patterns.
+* During rolling upgrades where Node A (Version $N$) and Node B (Version $N+1$) run concurrently, both versions operate against the shared schema without structural conflicts.
+
+---
+
+## 4. Split-Brain & Failure Behavior
+
+### 4.1 Split-Brain Risk Scenarios & Mitigation
+
+| Scenario | Risk | Mitigation Strategy |
+|---|---|---|
+| **Network Partition between Nodes** | Both Node A and Node B attempt to process operations for the same issue/PR. | **Generation Fencing:** Lease renewal requires updating the DB generation counter. The node isolated from the DB fails closed immediately. |
+| **Stale Node Recovery** | Node A recovers after a long pause and executes a queued mutation. | **Lease Expiry & TTL Fencing:** Transactions verify that `expires_at > NOW()` within the atomic SQLite transaction boundaries. |
+| **Database Connection Loss** | Node loses access to shared control-plane DB substrate. | **Strict Fail-Closed:** The node immediately marks all task capabilities as `blocked` and rejects mutation tools until DB connectivity is re-established. |

+    M2 --> M3[Milestone 3: Health Routing & Standby Failover]
+    M3 --> M4[Milestone 4: Active-Active Rolling Deployment & Auto-Drain]
+```
+
+### Milestone 1: Shared Control-Plane DB Schema & Resume Tokens (Post-#655)
+* Extend [#613] Control-Plane DB schema to store multi-instance node heartbeat records and session resume tokens.
+* Enable session lookup across instances via `session_id`.
+
+### Milestone 2: Idempotent Mutation Layer & Lease Fencing
+* Add mandatory `idempotency_key` tracking to all Gitea mutation tools.
+* Implement monotonic lease fencing counters in `gitea_allocate_next_work` and `gitea_adopt_workflow_lease`.
+
+### Milestone 3: Health-Based Routing & Active-Passive Standby
+* Introduce lightweight proxy/router capable of checking node health endpoints.
+* Implement active-standby failover where standby node automatically assumes work if active node fails health checks.
+
+### Milestone 4: Active-Active Horizontal Deployment & Rolling Upgrade Automation
+* Enable true active-active multi-instance execution.
+* Integrate automated zero-downtime rolling upgrades coordinated with `gitea_request_mcp_restart` maintenance drain.
+
+---
+
+## 6. Observability & Audit Requirements
+
+High-availability control plane operations must expose clear telemetry and audit trails:
+
+* **Node Registry Telemetry:** Active nodes, version numbers, uptime, and heartbeat timestamps reported via `gitea_get_runtime_context`.
+* **Lease Fencing Metrics:** Tracking lease acquire latency, fence rejection counts, and lease handoff durations.
+* **Failover & Re-route Audit Logs:** Durable logging of session migrations between nodes, drain initiation, and process retirement events.
+
+---
+
+## 7. Tradeoffs & Accepted Risks
+
+* **Increased Architectural Complexity:** Moving from a single process to a multi-instance control plane requires robust DB locking, proxy routing, and migration governance.
+* **Database Dependency:** The control-plane database substrate becomes a critical shared dependency for multi-node deployments. High availability for the underlying SQLite file system / DB must be guaranteed.

+# Incident #670: bare direct-to-master commit `2fa97c26` (retroactive audit)
+
+Status: verified; disposition recommendation: **accept as-is, no revert** (final
+disposition owned by controller per issue #670).
+
+## Summary
+
+Commit `2fa97c26fbda555a1a83930ca5fdcea9d8e47b50`
+(`fix(mcp): load dotenv relative to project root`) landed on `prgs/master`
+as a single-parent commit with no PR wrapper and no review record, bypassing
+the sanctioned issue → branch → PR → review → merge workflow. It was
+discovered during the PR #654 post-merge audit. PR #654 itself merged
+cleanly via the Gitea API and did **not** introduce this commit.
+
+## Verification evidence (acceptance criteria 1–3)
+
+- **AC1 — present on `prgs/master`: yes.**
+  `git merge-base --is-ancestor 2fa97c26fbda555a1a83930ca5fdcea9d8e47b50 prgs/master` → true.
+- **AC2 — no PR or review record: confirmed.**
+  The commit is a single-parent, non-merge commit sitting directly on
+  first-parent master between the #629 merge (`5ab5fe85`) and the #654
+  merge (`ec903b0d`). A PR landing on master produces a merge commit (or a
+  PR-linked head); neither exists here. The controller audit at issue-create
+  time also found no PR wrapper and no review record for this SHA.
+- **AC3 — changed files and diff summary: confirmed.**
+  `gitea_auth.py | 5 +++--` (+3/−2). Single parent
+  `5ab5fe8583c07134d55dadf09381aecb67df246e`. The change moves
+  `PROJECT_ROOT` derivation above `load_dotenv()` and loads
+  `.env` relative to the project root instead of the process CWD.
+
+## AC4 — why no immediate revert
+
+- The dotenv fix is intentional and required for correct runtime behavior:
+  without it, `load_dotenv()` resolves `.env` against the process working
+  directory, which breaks MCP server launches whose CWD is not the project
+  root.
+- The change is small (+3/−2), self-contained in `gitea_auth.py`, and has
+  been running on master without incident since 2026-07-10.
+- Reverting would re-introduce a real bug to remove a provenance defect —
+  the wrong trade. Provenance is repaired retroactively by this document,
+  issue #670, and the hardening landed under #671.
+- If the controller later judges the change unsafe, a separate
+  revert/repair issue is the sanctioned path (issue #670, recommended
+  disposition option 4).
+
+## AC5 — workflow-hardening linkage
+
+Prevention already landed: **issue #671** (closed)
+*“Block direct pushes to stable branches from MCP workflow sessions”*,
+implemented by commit `5933d87647656643a67a50331c4c7b06ea751dad`
+(`feat(guard): block direct stable-branch pushes from MCP workflow sessions`).
+
+Shipped guardrails include:
+
+- `gitea_record_stable_branch_push_attempt` — classifies proposed commands
+  for direct stable-branch push intent (`git push <remote> master`,
+  refspecs, `HEAD:master`, `--force`, dry-run intent, `:master` delete),
+  plus root/control-checkout local commits not carried by an issue branch,
+  and writes a durable `stable_branch_contamination` marker.
+- `gitea_audit_stable_branch_contamination` — reconciler-only audit/clear
+  path; a contaminated worker session cannot self-clear.
+- Review/merge/close/completion mutations fail closed while a
+  contamination marker is active.
+
+## AC6 — PR #654 was not the source
+
+- `2fa97c26` is the **first parent** of the #654 merge commit
+  `ec903b0d619e7a27d24aed272a890f4e5d381411`; it predates the #654 merge.
+- First-parent history `5ab5fe8..ec903b0`:
+  `2fa97c2 fix(mcp): load dotenv relative to project root` followed by
+  `ec903b0 Merge pull request 'feat: lifecycle role/hazard labels ... (#603)' (#654)`.
+- The #654 merger audit confirmed `ec903b0d` was a valid Gitea-API merge,
+  the `git push prgs master` attempt during that run was a no-op, and the
+  net change `2fa97c2..ec903b0` contained only the reviewed #603
+  lifecycle-label files.
+- Conclusion: #654 merged reviewed content only; the unauthorized-path
+  defect is solely the earlier bare commit `2fa97c26`.
+
+## Explicit non-actions (unchanged by this audit)
+
+- No revert of `2fa97c26`.
+- No force-push or history rewrite.
+- No master mutation from the audit session.

+## Sanctioned reconnect vs forbidden manual launch (#686)
+
+In addition to manual process killing (#630), manually launching a duplicate role server from an ad hoc shell (`python3 mcp_server.py`) is forbidden and fail-closed:
+
+- **Why manual launches are unsupported:** A terminal-launched `mcp_server.py` holds its own stdio transport; it can never bind to the IDE client's stdio pipes. It cannot restore a dropped IDE namespace, and a manual duplicate process masks stale client-managed runtimes for that profile, defeating stale-runtime gates.
+- **Sanctioned path:** Supported recovery is IDE/client-managed reconnect only (`/mcp reconnect`, IDE restart, or sanctioned reconnect exposure).
+- **Fail-closed enforcement (#686):** Mutating tools on a server lacking client-managed launch provenance (`GITEA_CLIENT_MANAGED=1`) refuse execution fail-closed with typed blocker `unsupported_manual_launch` and an exact next action. Unsupported `GITEA_*` env overrides (e.g. `GITEA_DUMMY`) are surfaced in diagnostics rather than silently ignored.
+- **Inventory & staleness:** Staleness diagnostics ignore non-client-managed duplicates when evaluating runtime freshness and inventory duplicate processes per profile (#657, #686).

+narrowest recommended action, then walks the ladder. Soft recommendations
+never replace the hard gate on broad restarts.
+
+## Enforcement points
+
+1. **`recovery_playbook.assess_escalation`** — pure gate.
+2. **`restart_coordinator.evaluate_restart_impact`** — when `restart_class` is
+   set (policy-enforced path), broad classes require the gate; report fields
+   `attempt_log_satisfied`, `playbook_escalation`, `break_glass`.
+3. **`gitea_request_mcp_restart`** — accepts attempt JSON and env-authorized
+   break-glass; never restarts a process.
+
+## Metrics
+
+`recovery_playbook.recovery_metrics(attempts)` reports the fraction of
+successful recoveries that avoided full/host restart
+(`fraction_avoided_full_restart`).
+
+## Non-goals
+
+* HA multi-instance execution (#668 design only here).
+* Normalizing `pkill` (#630 contamination stays forbidden).
+* Silent mutation of leases or processes from the playbook itself.

+## Manual process kills
+
+Remain forbidden and contaminating (#630). The playbook never recommends them.

+| Field | Meaning |
+| ----- | ------- |
+| **Anchor** | `file:line` at the commit under review. |

+| **Observes remotely** | What the same code would actually see on a shared remote host. |

+Classification meanings:
+
+- **portable as written** — the code is already transport-, host-, and principal-neutral; it
+  moves unchanged once its inputs are supplied by a remote-aware caller.
+- **needs a seam** — the logic is correct but is wired to a hard-coded local source. It needs
+  an injection point, not new semantics.
+- **needs a replacement** — the semantics themselves are local-only. A remote deployment
+  needs a differently-defined mechanism, not the same mechanism relocated.
+- **cannot be remote** — the operation is inherently about the operator's own machine
+  (its process table, its keychain, its checkout). It must either stay local behind an
+  explicit boundary or be deleted from the remote surface.

+## 1. Transport bind
+
+The transport is bound literally, once, at process start, and the bound value is the root of
+the mutation-authorization chain.
+
+| ID | Anchor | Assumes today | Observes remotely | Class | Owner |
+| -- | ------ | ------------- | ----------------- | ----- | ----- |
+| T1 | `gitea_mcp_server.py:23750` | The single production bind call passes the literal `transport="stdio"` immediately before the server loop. | The literal is wrong for any non-stdio deployment; there is no parameter to change it. | needs a seam | #931 |
+| T2 | `mcp_daemon_guard.py:45` | `_PRODUCTION_TRANSPORTS = frozenset({"stdio"})` is the closed allowlist of production transports. | A remote transport name is rejected by the allowlist before any other check runs. | needs a seam | #931 |
+| T3 | `mcp_daemon_guard.py:174` | `bind_native_mcp_transport` raises `UnsanctionedRuntimeError` for any transport outside `_PRODUCTION_TRANSPORTS` (raise at `mcp_daemon_guard.py:187`). | The remote server fails to start rather than degrading; the failure is correct, but the allowlist is the only thing that must change. | needs a seam | #931 |
+| T4 | `mcp_daemon_guard.py:328` | `is_native_mcp_transport()` asserts a process-local runtime record whose `pid` matches `os.getpid()` and whose phase is `transport_bound`. The predicate itself names no transport. | Unchanged semantics: one server process that bound one transport. It stays true on a remote host. | portable as written | #931 |
+| T5 | `mcp_daemon_guard.py:349` | `is_production_native_mcp_transport()` adds only a `mode == production` check on top of T4. | Unchanged. | portable as written | #931 |
+| T6 | `irrecoverable_provenance.py:497` | `assess_transport_for_auth_mint()` requires production native transport before minting non-forgeable recovery authorization (#709 F1). | The gate is transport-agnostic in form, but its guarantee — "an ordinary Python process cannot reach this" — is currently underwritten by the stdio bind. Under a remote transport the guarantee must be re-derived from the authenticated session, not from the bind. | needs a seam | #931 |
+| T7 | `gitea_mcp_server.py:8375` | Consumer: refuses to proceed unless `assess_transport_for_auth_mint()` allows. | Unchanged given a corrected T6. | portable as written | #931 |

+| P4 | `gitea_mcp_server.py:20599` | `_check_mcp_runtimes_diagnostics()` shells `ps -o pid,lstart,command -ax` and greps for `mcp_server.py` to find peer role servers. | On a shared host the process table lists unrelated tenants' processes, or none at all under a container.

+| P7 | `gitea_config.py:1172` | `RECOGNIZED_GITEA_ENV_KEYS` is the allowlist of `GITEA_*` env vars a legitimately launched server may carry; anything else is contamination. | Configuration on a remote host arrives from deployment tooling, not from a client-authored env block. The allowlist keeps working mechanically but stops proving anything about provenance. | needs a replacement | #934 |
+| P8 | `gitea_mcp_server.py:20683` | The unsupported-env scan applies `RECOGNIZED_GITEA_ENV_KEYS` to *other* processes' environments harvested via `ps eww <pid>`. | Reading another process's environment is unavailable or prohibited across tenants, and is not exposed in this form outside macOS/BSD `ps`. | cannot be remote | #934 |
+| P9 | `mcp_daemon_guard.py:126` | `mark_sanctioned_daemon()` requires the claiming stack frame's resolved absolute path to be the canonical `mcp_server.py` / `gitea_mcp_server.py` next to the guard module; basename spoofing is rejected. | Entrypoint-path identity still exists on a remote host, but it authenticates the *deployment*, not the *caller*. It must be kept and demoted from "authorizes mutations" to "authorizes the process". | needs a seam | #934 |
+| P10 | `gitea_config.py:1233` | The client-config generator emits `"GITEA_CLIENT_MANAGED": "1"` into each generated MCP client entry, alongside `GITEA_MCP_CONFIG` / `GITEA_MCP_PROFILE`. | A remote endpoint is addressed by URL and credential, not by a spawn command with an env block. This generator produces the wrong artifact entirely. | needs a replacement | #938 |
+| P11 | `mcp_namespace_health.py:232` | Namespace health classifies a namespace as `client_managed` or `manual_launch` from the reported env summary. | During dual-run, local and remote namespaces coexist and must both be classifiable; a two-valued local/manual axis cannot express "remote endpoint, authenticated session". | needs a replacement | #939 |
+| P12 | `gitea_mcp_server.py:18161` | The diagnostics payload reports `server_provenance` as exactly `"client_managed"` or `"manual_launch"`. | This is the field a cutover operator reads to confirm which deployment served a call. It must gain a remote value before dual-run parity can be validated. | needs a replacement | #939 |
+
+## 3. Role binding
+
+Role separation is currently enforced by *which process a call reaches*. The process is pinned
+to one role for its lifetime by an environment variable.
+
+| ID | Anchor | Assumes today | Observes remotely | Class | Owner |
+| -- | ------ | ------------- | ----------------- | ----- | ----- |
+| R1 | `gitea_config.py:54` | `ENV_PROFILE = "GITEA_MCP_PROFILE"` is the single source of the active profile, read from the process environment. | One shared process serves several principals; a process-wide profile cannot answer "who is calling now". This is the root of the coupling. | needs a replacement | #932 |
+| R2 | `review_workflow_load.py:95` | Reads `GITEA_MCP_PROFILE` directly to decide the reviewer workflow binding. | Reads the deployment's profile, not the caller's, silently granting or denying the wrong role. | needs a replacement | #932 |
+| R3 | `mcp_discoverability.py:152` | Reads `GITEA_MCP_PROFILE` to describe the namespace to the client. | Correct logic, wrong input source; it needs the request principal injected. | needs a seam | #932 |
+| R4 | `webui/deployment_boundary.py:115` | Reads `GITEA_MCP_PROFILE` to classify the deployment boundary for the console. | Same as R3. | needs a seam | #932 |
+| R5 | `gitea_mcp_server.py:21106` | Remediation text instructs the operator to "Relaunch the server with `GITEA_MCP_PROFILE` set to a profile that has the required permission". | Relaunching a shared remote endpoint to change one caller's role is not a valid instruction; it would re-role every other session. | needs a replacement | #932 |
+| R6 | `native_mcp_preference.py:93` | Detects shell commands that override `GITEA_MCP_PROFILE` away from the session (`native_mcp_preference.py:223`) and flags them as CLI auth divergence. | The divergence check is genuinely useful and survives, but its notion of "the session's profile" must come from the request principal. | needs a seam | #932 |
+| R7 | `gitea_mcp_server.py:20671` | Recovers a peer server's role by regexing `GITEA_MCP_PROFILE=` out of that process's environment. | Depends on P4/P8 process-table access; role discovery by peer-env scraping has no remote analogue. | cannot be remote | #932 |
+
+## 4. Credentials
+
+Every token resolves, directly or indirectly, from one human's macOS keychain.
+
+| ID | Anchor | Assumes today | Observes remotely | Class | Owner |
+| -- | ------ | ------------- | ----------------- | ----- | ----- |
+| C1 | `gitea_config.py:956` | `_keychain_token()` shells `security find-generic-password -s <item> -w`. | `security(1)` is a macOS binary reading the calling user's login keychain. It does not exist on a Linux host and would be the wrong identity even on a shared Mac. | cannot be remote | #933 |
+| C2 | `gitea_config.py:974` | `resolve_token(profile, keychain_lookup=_keychain_token)` dispatches on `auth.type` of `env` or `keychain`, defaulting the lookup to C1. | The injectable `keychain_lookup` parameter is the existing seam; a remote credential provider plugs in here without changing the dispatch. | needs a seam | #933 |
+| C3 | `gitea_config.py:1015` | `keychain_auth(item_id)` constructs the `{"type": "keychain", "id": ...}` reference stored in profiles. | The reference type itself encodes "macOS keychain" into persisted config. A remote provider needs a new auth reference type, not a new value of this one. | needs a replacement | #933 |
+| C4 | `mcp_daemon_guard.py:440` | `assert_keychain_access_allowed()` fails closed for git-credential keychain fill outside a sanctioned daemon, with an operator opt-out env var. | The gate protects a mechanism that will not exist remotely. Its replacement must gate the *credential provider* call, not the keychain call, or the protection silently lapses. | needs a replacement | #933 |
+| C5 | `sentry_incident_bridge.py:190` | `resolve_token(env)` resolves the Sentry token from an injected env mapping with no keychain path. | Already host-neutral; it is the shape the Gitea credential path should converge on. | portable as written | #933 |
+| C6 | `gitea_mcp_server.py:18469` | The profile-audit tool calls `gitea_config.resolve_token(p)` for every configured profile to report "credentials present" without networking. | On a remote host this would materialize every principal's credential inside one process — an audit surface that becomes a credential-aggregation risk. | needs a seam | #933 |
+
+## 5. Runtime freshness
+
+The mutation gate is defined as "the commit this process started at matches the checkout on
+this disk, and both match live master". Two of those three terms are local-disk facts.
+
+| ID | Anchor | Assumes today | Observes remotely | Class | Owner |
+| -- | ------ | ------------- | ----------------- | ----- | ----- |
+| F1 | `master_parity_gate.py:168` | `capture_startup_parity(root)` reads git `HEAD` from the server's own root once at startup and returns it as the baseline. | A remote host carries a deployed artifact, not the operator's checkout. Its `HEAD` says nothing about the operator's working tree, which is the thing the gate exists to protect. | cannot be remote | #935 |
+| F2 | `master_parity_gate.py:255` | `mutation_safe = determinable and in_parity and live_known and not live_stale` — a conjunction of two local-HEAD comparisons and one live-remote comparison. | Two of the three conjuncts lose meaning, so the whole verdict does. A remote deployment needs a redefined, testable freshness predicate rather than this one relocated. | needs a replacement | #935 |
+| F3 | `master_parity_gate.py:164` | The live-remote head is probed and cached per `(root, remote, branch)`, keyed on the local root. | The live-remote probe is the one conjunct that survives; it needs a key that is not the operator's filesystem path. | needs a seam | #935 |
+| F4 | `gitea_mcp_server.py:18262` | `gitea_assess_master_parity` publishes `startup_head` / `local_head` / `live_remote_head` / `mutation_safe` as the authoritative mutation-safety verdict. | The tool's contract is consumed by every mutation caller and by the operator; it must keep its shape while its semantics are redefined, or every consumer breaks at once. | needs a replacement | #935 |
+| F5 | `gitea_mcp_server.py:23054` | Falls back to `_process_boot_head_sha` — the commit this process booted at — when the parity payload has no `startup_head`. | Same defect as F1, in a fallback path that is easy to miss when F1 is fixed. | needs a seam | #935 |
+| F6 | `gitea_mcp_server.py:20615` | Staleness is also inferred from `os.path.getmtime()` of `gitea_mcp_server.py` under `PROJECT_ROOT` (`gitea_mcp_server.py:20611`), compared against peer process start times. | File mtime on a deployed artifact tracks the deploy, not the operator's edits, and the peer start times it is compared against come from the unavailable process table (P4). | cannot be remote | #935 |
+
+## 6. Local filesystem
+
+Author and reviewer tools act directly on the operator's checkout.
+
+| ID | Anchor | Assumes today | Observes remotely | Class | Owner |
+| -- | ------ | ------------- | ----------------- | ----- | ----- |
+| L1 | `gitea_mcp_server.py:10122` | `gitea_bootstrap_author_issue_worktree` creates and binds a git worktree on the server's own disk. | The remote host has no operator checkout to add a worktree to. Executing this remotely would act on the wrong disk while reporting success. | cannot be remote | #936 |
+| L2 | `gitea_mcp_server.py:190` | `ACTIVE_WORKTREE_ENV = "GITEA_ACTIVE_WORKTREE"` and `AUTHOR_WORKTREE_ENV` (`gitea_mcp_server.py:191`) carry the active workspace as process-wide environment. | Process-wide workspace state cannot represent per-session workspaces on a shared endpoint. | needs a replacement | #936 |
+| L3 | `gitea_mcp_server.py:9801` | Binding a worktree writes `os.environ["GITEA_AUTHOR_WORKTREE"]` and `os.environ["GITEA_ACTIVE_WORKTREE"]` (`gitea_mcp_server.py:9802`), mutating global process state. | One session's bind would silently retarget every other concurrent session in the same process. This is a correctness bug the moment concurrency is real. | needs a replacement | #936 |
+| L4 | `reviewer_inventory_worktree.py:48` | `_BRANCHES_WORKTREE_RE = re.compile(r"\bbranches/", re.I)` requires review worktree paths to sit under `branches/`. | A path convention on the operator's machine, asserted as a validation rule. It needs to become a property of a declared workspace, not a substring test. | needs a seam | #936 |
+| L5 | `stable_control_runtime.py:54` | `DEV_WORKTREE_SEGMENT = "branches"` classifies a process root as a development worktree by path segment. | Same class of assumption as L4, on the runtime-classification side. | needs a seam | #936 |
+| L6 | `mcp_server.py:42` | `check_conflict_markers()` runs at import and `os.walk`s the install directory for unresolved conflict markers, `sys.exit(1)` on a hit. | On a remote host it scans a deployed artifact, which by construction never has conflict markers — so the guard passes trivially and stops protecting the thing it was written to protect. | needs a replacement | #936 |
+| L7 | `role_session_router.py:487` | `check_mid_merge()` reports infra-stop from `.git/MERGE_HEAD`, `rebase-merge`, `rebase-apply` and a source conflict scan under the server's project root. | Same inversion as L6: it would report the deployment's git state, not the operator's. | needs a replacement | #936 |
+| L8 | `author_issue_bootstrap.py:996` | Enumerates worktrees with `git -C <root> worktree list --porcelain`. | Requires a real local clone with real worktrees; there is nothing equivalent to enumerate remotely. | cannot be remote | #936 |
+| L9 | `mcp_server.py:10` | Redirects `sys.stderr` to the fixed path `/tmp/mcp_server_stderr.log` outside pytest. | A single fixed `/tmp` path is shared by every concurrent server on a host and is not a deployment's logging surface. | needs a replacement | #938 |
+| L10 | `gitea_mcp_server.py:2314` | `ISSUE_LOCK_FILE = "/tmp/gitea_issue_lock.json"` — the legacy single global lock slot. | One global `/tmp` slot per host cannot represent concurrent remote sessions and is world-visible on a shared machine. | needs a replacement | #937 |
+| L11 | `issue_lock_provenance.py:14` | `ISSUE_LOCK_FILE = os.environ.get("GITEA_ISSUE_LOCK_FILE", "/tmp/gitea_issue_lock.json")` keeps the same `/tmp` default in the provenance path. | Same as L10; the env override is a local escape hatch, not a remote design. | needs a replacement | #937 |
+
+## 7. Durable state
+
+Locks, leases, session state, and the control-plane database live in the operator's home
+directory and are keyed on local PIDs.
+
+| ID | Anchor | Assumes today | Observes remotely | Class | Owner |
+| -- | ------ | ------------- | ----------------- | ----- | ----- |
+| S1 | `issue_lock_store.py:26` | `DEFAULT_LOCK_DIR = ~/.cache/gitea-tools/issue-locks` — per-issue lock files under one user's home. | A shared endpoint has no single operator home; per-user paths make locks invisible across sessions and hosts. | needs a replacement | #937 |
+| S2 | `issue_lock_store.py:83` | `session_pointer_path()` names the session pointer file `session-<os.getpid()>.json`. | Many sessions share one PID on a remote server, so the pointer collapses to a single slot and sessions overwrite each other. | cannot be remote | #937 |
+| S3 | `issue_lock_store.py:98` | `is_process_alive(pid)` decides lock liveness by probing the local process table. | A PID recorded by one host is meaningless on another, and may coincidentally match a live unrelated process. | cannot be remote | #937 |
+| S4 | `issue_lock_store.py:213` | Lock records stamp `session_pid` and `pid` from `os.getpid()`. | The recorded identity no longer distinguishes sessions; ownership checks silently pass for the wrong caller. | needs a replacement | #937 |
+| S5 | `mcp_session_state.py:27` | `DEFAULT_STATE_DIR = ~/.cache/gitea-tools/session-state`, mode `0o700`. | Same home-directory coupling as S1, for review decision locks and workflow proofs. | needs a replacement | #937 |
+| S6 | `mcp_session_state.py:559` | Session bodies stamp `session_pid` and `writer_pid` from `os.getpid()` (`mcp_session_state.py:560`). | Writer attribution collapses across concurrent sessions in one process. | needs a replacement | #937 |
+| S7 | `control_plane_db.py:47` | `DEFAULT_DB_PATH = ~/.cache/gitea-tools/control-plane/control_plane.sqlite3`. | A per-user SQLite file is not reachable by, or safe for, multiple remote sessions or multiple hosts. | needs a replacement | #937 |
+| S8 | `control_plane_db.py:386` | `sqlite3.connect(self.db_path, timeout=30)` — single-writer file locking tuned for one local process. | SQLite's write lock does not extend across hosts and degrades sharply under real concurrency; the store needs a concurrency-safe backend. | needs a replacement | #937 |
+| S9 | `control_plane_db.py:1145` | Lease rows record `owner_pid` defaulting to `os.getpid()` (also `control_plane_db.py:2039`). | PID-keyed lease ownership is unusable across hosts and ambiguous within one shared process. | cannot be remote | #937 |
+| S10 | `mcp_daemon_guard.py:53` | `_DEFAULT_SESSION_STATE_DIR` is pinned once at transport bind so a later `GITEA_MCP_SESSION_STATE_DIR` change cannot manufacture a second authority domain (#695 AC2). | The single-authority-domain invariant is exactly right and must be preserved; only its backing location needs to move. | needs a seam | #937 |
+| S11 | `gitea_mcp_server.py:11875` | Reviewer-lease reclaim reads `owner_pid_alive` from the lease freshness record to decide whether an owner is dead. | Consumes S3/S9; a false "owner alive" or "owner dead" here reclaims or refuses a live lease. This is the highest-consequence consumer of PID liveness. | cannot be remote | #937 |

+## Notes for downstream children
+
+- **The three highest-risk entries are P5, F2, and S11.** Each is a guard that does not
+  merely stop working remotely — it inverts. P5 turns concurrency into a reported fault,
+  F2 returns a verdict computed from terms that no longer mean anything, and S11 reclaims
+  or refuses leases on a PID-liveness answer that is wrong rather than unknown. A gate that
+  fails open while still reporting green is worse than one that fails to start.
+- **T4, T5, T7, T8, and C5 are the portable core.** They show the target shape: predicates
+  over injected inputs, with no reference to the host, the process table, or the operator's
+  disk.
+- **The keychain seam already exists** at C2 (`resolve_token`'s injectable `keychain_lookup`).
+  #933 should widen that seam rather than introduce a parallel path, and must remember C4 —
+  the guard protecting the old mechanism has to be re-pointed, or the protection lapses
+  silently when the mechanism is replaced.
+- **`branches/` appears as a validation rule in at least two independent places** (L4, L5).
+  Path-substring conventions tend to have more copies than expected; #936 should re-grep
+  rather than trust this list to be exhaustive for that specific pattern.

+
+## 1. Overview
+
+The **Notifications & Human-Attention Console** (`/notifications`, `/api/v1/notifications`) provides intelligent event classification and human-attention routing for autonomous workflow operations.
+
+To prevent alert fatigue while ensuring critical escalation boundaries are never missed, events are classified into three distinct **Attention Classes**:
+
+1. **`human-required`** (Urgent Escalation Boundary):
+   - Items requiring immediate human intervention or business decisions.
+   - Triggers: Auth failures, hard stops, irrecoverable state, decision locks, failed report validations, critical probe errors.
+   - Display: Highlighted in red (`badge-blocked`) with a `HUMAN REQUIRED` badge.
+
+2. **`operator`** (Operational Inbox):
+   - Items requiring controller or operator review/triage during routine execution.
+   - Triggers: Blocked PRs (merge conflicts), stale leases, duplicate PRs on issues, unassigned ready work.
+   - Display: Displayed in orange/yellow (`badge-claimed`).
+
+3. **`routine`** (Background Workflow Transitions):
+   - Normal, healthy workflow transitions and state progressions.
+   - Triggers: Active PRs/issues in standard state, clean branch creation, routine heartbeats.
+   - Display: Filtered out of default inbox views to eliminate notification spam; viewable on demand via the "Routine" or "All" tab.

+# Web Console: restart status, impact preview, and approval state (#667)
+
+Phase 1 of the console restart surface. It consumes the #655 coordinator
+substrate and displays it. It performs no restart, reload, drain, approval, or
+process action, and it registers no write endpoint.
+
+Issue #667's rollout is explicit — *status views first, write approval after the
+backend gates are green* — and this change delivers only the status half.
+
+## Surfaces
+
+| Path | Method | Purpose |
+|------|--------|---------|
+| `/runtime/restart` | GET | Restart status page |
+| `/api/v1/system/restart/status` | GET | Same snapshot as JSON |
+
+Both accept an optional `restart_class` query parameter (default
+`full_mcp_restart`). An unrecognised class is not an error: the coordinator
+resolves it as unknown and fails closed, and the page shows the resulting deny.
+
+Neither path accepts `POST`; a write attempt returns `405`, and a test asserts
+it.
+
+## What it shows
+
+* **Impact preview (#658)** — verdict, blast radius, affected sessions, leases,
+  critical sections, mutations, and the counts behind them, evaluated
+  `dry_run=True` against live control-plane state.
+* **Drain proof (#661)** — verification of a supplied proof: valid, clean,
+  expired, tampered, and the reasons behind a refusal.
+* **Post-restart reconcile (#662)** — the most recent completion proof, its
+  overall status, and which dimensions still require follow-up.
+* **Restart classes (#663)** — the least-privilege matrix, with *you may
+  request* and *you may execute* computed for the viewing role rather than for a
+  generic operator.
+* **Approval controls (#633)** — the authorization state of
+  `system.restart_namespace` and `system.reload_namespace`.
+* **Break-glass (#664)** — declared and marked unavailable; see below.
+
+## Three rules this surface holds itself to
+
+A status page that is wrong is worse than one that is missing, because an
+operator acts on it. Three properties are enforced by tests, and each was
+verified by reverting the guard and watching a test fail.
+
+### An unreadable source reports unavailable, never green
+
+Every source carries its own `SourceStatus`. Nothing substitutes a default,
+placeholder, or self-comparison for a reading that failed. An unreadable
+control-plane database yields `inventory_complete: false`, which the coordinator
+itself turns into a fail-closed verdict, and the page says the blast radius is
+unknown rather than showing an empty affected-sessions table.
+
+An absent drain proof is reported as absent — not as a pass. The #661 gate
+authorizes a restart only against a valid, unexpired, clean proof, so no proof
+is precisely the state that gate denies on.
+
+### Authorization is asked the way execution would ask it
+
+Every probe passes `for_execution=True`.
+
+Asked without it, an admin is `allowed` for `system.restart_namespace`. On a
+control surface that reads as a live button. Asked the way an execution attempt
+would ask, the same principal is refused `phase_not_active`, because the console
+is in Phase 1 and the action is Phase 2. This surface reports the second answer.
+
+`execution_enabled` is therefore `false` for every action and every role today,
+and a test asserts that across the whole role matrix.
+
+### The control-plane database is opened read-only
+
+`ControlPlaneDB()` creates directories and runs migrations on construction — a
+write. This surface never constructs one. It opens the sqlite file with
+`mode=ro`, exactly as `webui/inventory.py` does, and treats a missing file as
+missing authority rather than as an empty inventory.
+
+The test that protects this points at a path inside a directory that already
+exists, so a read-write `connect` would really create the file. A nested
+missing-directory path would have passed for the wrong reason.
+
+## Break-glass is declared, not offered
+
+The break-glass workflow (#664) is not available on this branch's base. The
+panel is rendered to operator-class roles as **unavailable**, naming the issue
+that tracks it. It is not silently omitted, because an operator who has been
+told a governance path exists needs to see that it is not wired here; and it is

+Every interpolated value passes through `_esc` (`html.escape(..., quote=True)`).
+Free-form text and anything that can carry a filesystem path additionally passes
+through `webui.inventory.scrub_text`, which redacts credential-shaped tokens
+inside a string rather than only at its start. The impact payload is passed
+through `webui.inventory.scrub` before rendering.

+"""Scoped MCP recovery playbook (#669).

+Operational recovery must prefer the *narrowest* action that can fix the
+symptom. Full MCP / host restarts are last-resort rungs on a documented
+ladder; the coordinator refuses those rungs unless a prior attempt log
+shows narrower recoveries already failed (or break-glass is authorized).
+
+This module is pure classification and recommendation:
+
+* No network, filesystem, or process I/O.
+* Never restarts anything.
+* Narrow recovery *execution* is delegated to existing tools/docs (linked
+  per rung) — the playbook records which rung to try next and whether
+  escalation to a broad restart is allowed.

+"""Regression: author bootstrap scope reaches workflow_scope_guard (#941).
+
+PR #926 (#892) made ``bootstrap_permits_control_checkout`` accept
+``task_scope=author_issue_bootstrap`` and wired that canonical decision into
+the #274 branches-only enforcer and the #604 anti-stomp preflight. A third
+enforcement path was left unwired.
+
+``workflow_scope_guard.assess_root_source_mutation`` kept its own copy of the
+clean-root author decision, gated on ``create_issue_bootstrap.is_create_issue_task``
+— a task-name allowlist that never contained ``bootstrap_author_issue_worktree``.
+So the real call path
+
+    gitea_bootstrap_author_issue_worktree
+      -> verify_preflight_purity
+        -> _enforce_issue_scope_guard
+          -> workflow_scope_guard.assess_production_mutation_guards
+
+raised ProductionGuardError(missing_issue_worktree) before
+``assess_author_issue_bootstrap`` was ever consulted.
+
+These tests drive the real enforcer, not the authorization helper in
+isolation. A helper-only test cannot observe this defect: #892's own predicate
+tests all passed while the live bootstrap stayed blocked.

+"""Exact-owner renewal keeps its owning-PR waiver past lock_issue (#945).
+
+#755 taught the duplicate-work gate that a sanctioned *dead-session recovery*
+owns its open PR, and #768 taught the later gates to rebuild that proof from the
+durable lock. #760 added the exact-owner *renewal* disposition and granted it
+the same waiver inside ``gitea_lock_issue`` — but never added the matching
+rebuild. So an ordinary renewal held the waiver only for the duration of the
+lock call: ``_enforce_locked_issue_duplicate_recheck`` asked
+``recovered_owning_pr_from_lock``, which reads only ``dead_session_recovery``,
+and the very next commit was refused ``duplicate_commit_prevented`` with
+``owning_pr_recovery_exempted: false`` on the PR the renewal had just proved.
+
+``TestPreFixReproduction`` pins that defect directly: the recovery-only rebuild
+still returns ``None`` for a renewal lock, which is exactly why the gates lost
+the waiver. Everything else proves the renewal half now survives, that recovery
+is unchanged, and that no path grants an exemption on weaker evidence.
+
+Every fixture here is an in-memory mapping. Nothing writes a branch, worktree,
+lock file, lease, comment, or PR (#945 AC18).

+"""Concurrent-session MCP restart safety & dogfooding test suite (#666).
+
+Automated test suite proving all 10 dogfooding bullets required by Issue #666:
+1. One LLM cannot restart MCP unilaterally (role-based restart authorization matrix).
+2. New work stops during drain (assignments_stopped gate enforcement).
+3. Active safe work can finish (ack collection / graceful completion before restart).
+4. Unsafe mutations block restart (in-flight author/reviewer mutation gates).
+5. Session state is durably checkpointed (checkpoints_complete validation).
+6. Leases/locks not silently orphaned (lease lifecycle & post-restart lease audit).
+7. Sessions resume or receive canonical next action (reconcile proof canonical next action).
+8. Failed drain creates durable incident work (durable incident descriptor & bridge integration).
+9. Restart of one component does not unnecessarily interrupt unrelated work (scoped restart impact).
+10. Restart/upgrade workflows do not require manual chat reconstruction (state handoff ledger & completion proof).

+
+The console consumes the #655 substrate. These tests hold it to the three
+properties that make a status surface trustworthy:
+
+* an unreadable source is reported unavailable, never rendered as green;
+* authorization is probed the way execution would probe it, so an allow is
+  never shown for something that could not run;
+* the surface performs no mutation, including no write to the control-plane DB.

+"""Read-only restart status, impact preview, and approval state (#667).
+
+Phase 1 of the console restart surface. It *consumes* the #655 coordinator
+substrate and renders it; it never restarts, reloads, drains, approves, or kills
+anything. There is no apply path in this module, so there is no execution gate
+here to arm incorrectly — the only writes the console could perform are the ones
+it does not implement.
+
+Sources, each independently fail-soft and each reported with its own
+:class:`SourceStatus`:
+
+* :mod:`restart_coordinator` — restart-class policy matrix (#663) and the
+  blast-radius impact report (#658).
+* :mod:`drain_proof` — drain checklist and gate verdict (#661), verified
+  read-only against a caller-supplied proof.
+* :mod:`post_restart_reconcile` — post-restart completion proof (#662).
+* :mod:`webui.console_authz` — role authorization for the approval controls
+  (#633).
+
+Three rules this module holds itself to, because a status surface that lies is
+worse than one that is absent:
+
+**A source that could not be read is reported unavailable, never green.** No
+default, placeholder, or self-comparison is substituted for a reading that
+failed. An unreadable control-plane DB yields ``inventory_complete=False``,
+which the coordinator itself turns into a fail-closed verdict.
+
+**Authorization is asked the way execution would ask it.** Every authorization
+probe passes ``for_execution=True``, so the console reports whether the action
+could actually run rather than the weaker "this principal is the right role".
+While the console is in Phase 1 that answer is ``phase_not_active`` for every
+phase-2 action, and the surface says so plainly instead of showing an allow.
+
+**The database is opened read-only.** ``ControlPlaneDB()`` creates directories
+and runs migrations on construction, which is a write; this module opens the
+sqlite file with ``mode=ro`` exactly as :mod:`webui.inventory` does, and treats
+a missing file as missing authority rather than an empty inventory.
