fix(review): cross-PR decision-lock isolation and recovery diagnosis (Closes #693)

Prevent foreign open-PR terminals on the durable review-decision lock from
blocking fresh formal reviews. Scope correction authorization to the named
prior review's PR/head, add read-only diagnosis with exact next_action and
durable handoff payloads, require thread-visible correction audits, and
cover the PR #688 → #692 recovery sequence in regression tests.

-## Repository scope (#714)
-
-`allowed_repositories` declares the canonical `owner/repository` slugs a profile
-may operate on:
-
-```json
-"prgs-author": {
-  "allowed_repositories": ["Scaled-Tech-Consulting/Gitea-Tools"]
-}
-```
-
-It is an **authorization boundary, not the session binding**. The binding is
-derived and enforced like this:
-
-1. The session repository is derived from the **verified, workspace-aligned git
-   remote** — never from a caller-supplied `org`/`repo` argument, and never from
-   the `REMOTES` table (whose entries are default *targets*: `prgs` defaults to
-   `Timesheet`, which is not this project).
-2. That workspace-derived slug is validated against `allowed_repositories`.
-3. The session binds immutably to that one canonical `owner/repository`. The
-   organization is derived from the slug; there is no independent,
-   caller-controlled organization value.
-4. If a profile authorizes several repositories, the verified workspace still
-   selects exactly one. A session never binds to the whole list and never
-   switches between entries.
-
-Fail-closed rules:
-
-- Activation is rejected when the workspace repository is absent from the
-  allowlist.
-- A mutation is rejected when no verified workspace repository can be
-  established.
-- A tool-level `org`/`repo` override that disagrees with the binding is rejected
-  before the mutation runs.
-- A mutation request can never establish, complete, or replace the binding.
-
-The field is **config-only**: no environment variable can widen or forge it. It
-is optional — a profile that omits it keeps the previous behaviour, so existing
-static-profile namespaces stay functional until an operator provisions the
-scope. Provisioning it is what activates enforcement for that profile.

+Direct ``import gitea_mcp_server`` / ``import gitea_auth`` from a shell, plus
-#558 introduced a daemon marker; #695 hardens it so:
+raw keychain dumps, bypass preflight purity and role gates. Mutation helpers
+and keychain fallbacks therefore require an explicit sanctioned runtime.
 
-- Environment variables alone cannot reconstruct a native session
+Sanctioned contexts (any one):
-  (``GITEA_MCP_SANCTIONED_DAEMON=1`` / ``GITEA_ALLOW_DIRECT_MCP_IMPORT=1`` are
+- ``GITEA_MCP_SANCTIONED_DAEMON=1`` (set by the official MCP entrypoint)
-  insufficient for mutation gates).
+- pytest (``PYTEST_CURRENT_TEST`` present)
-- A process-local runtime record is established only by the resolved canonical
+- explicit operator opt-in ``GITEA_ALLOW_DIRECT_MCP_IMPORT=1`` (tests/tools only)
-  entrypoint path (not basename) **and** the actual native MCP transport
-  lifecycle (``bind_native_mcp_transport`` before ``mcp.run``). Merely
-  importing or launching the entrypoint offline does not grant mutation
-  authority.
-- Public caller-controlled flags (including any former
-  ``allow_test_bootstrap``) never establish trusted mutation provenance.
-- Offline scripts that import internals fail closed on mutations.
-- Pytest remains allowed for hermetic unit tests via ``is_pytest_runtime()``.
-  A separate test-only seam may establish a **test-mode** native record for
-  unit tests of transport gates; that record cannot authorize production
-  Gitea mutation endpoints.
 
-Manual deletion of session-state files is never a recovery path.
+Credential keychain fill additionally allows:
+- ``GITEA_ALLOW_KEYCHAIN_CLI=1`` for operator-only non-MCP scripts that must
+  use git-credential (never the default for LLM shells).

-Covers the original #698 lead plus the independent reproduction recorded
-during the PR #703 formal review (issue #698 comment 11246):
-
-1. non-dict ``action_log`` entries must fail structured, never crash;
-2. the validator must not demand legacy fields the canonical schema forbids
-   (``Pinned reviewed head``, ``Scratch worktree used``, ``Worktree path``,
-   ``Worktree dirty``, ``Mutations``, ``Next``);
-3. a legitimately blocked report (``Candidate head SHA: none``, no formal
-   verdict) must not owe approval/merge live-head proofs;
-4. canonical reviewer lease release must not be misclassified as post-merge
-   cleanup;
-5. structured workflow-load and validation proof must be recognized;
-6. review mutations are inferred only from authoritative evidence.

-construct a ``_SessionContext`` directly: the defect they cover is that the

-(``Scaled-Tech-Consulting/Gitea-Tools`` for this checkout), never from
