fix(session): require config-backed mutation authority and workspace-bound targets (#714)

Close the #714 remediation gap left at 943d402 where env-only mutation
profiles, REMOTES Timesheet defaults treated as explicit caller input, and
machine-dependent Git remotes produced false greens.

- Fail closed when mutations lack a config-backed profile with non-empty
  allowed_repositories; env ops cannot invent mutation authority.
- Preserve omitted-vs-explicit org/repo provenance through the mutation
  gate; omitted targets bind to the verified workspace repository.
- Prefer workspace-aligned Git remotes over historical Timesheet defaults
  in MCP _resolve and CLI resolve_remote.
- Centralize deterministic config-backed mutation fixtures; migrate
  mutation tests off env-only authority without weakening security
  assertions.

Full suite: 2744 passed, 6 skipped.

+## 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.

+`gitea_mcp_server` or ran credential helpers from a raw shell / offline helper,
+bypassing native MCP transport, preflight purity, and role gates. Contaminated

 ## Rule
 
-Mutation auth and keychain fill require a **sanctioned MCP daemon** process.
+Mutation auth, keychain fill, and controller quarantine require a **production
+native MCP transport runtime** established only by:
+
+1. the **resolved absolute path** of the canonical entrypoint
+   (`mcp_server.py` / `gitea_mcp_server.py` next to `mcp_daemon_guard.py`), and
+2. a live **transport bind** (`bind_native_mcp_transport(transport="stdio")`)
+   immediately before `mcp.run`.
+
+Basename-only trust (a renamed file called `mcp_server.py`), caller-controlled
+flags (there is **no** `allow_test_bootstrap`), environment variables, stack
+frame spoofing, or import-only launch are insufficient.
 
 | Context | Allowed |
 |---------|---------|
-| Official MCP entrypoint (`mcp_server.py` / `gitea_mcp_server` `__main__`) sets `GITEA_MCP_SANCTIONED_DAEMON=1` | yes |
+| Official IDE-native MCP: resolved canonical entrypoint marks + binds stdio, holds process-local runtime token | yes |
-| pytest | yes |
+| pytest (hermetic unit tests) via `is_pytest_runtime()` | yes for unit gates |
-| `GITEA_ALLOW_DIRECT_MCP_IMPORT=1` (operator/tests only) | yes |
+| `install_test_native_runtime()` under pytest (test-mode record) | unit-test transport gates only — **never** production Gitea mutations |

+| `allow_test_bootstrap=True` (removed; must not exist) | **no** |
-| keychain fill without daemon | **no** unless `GITEA_ALLOW_KEYCHAIN_CLI=1` |
+| Renamed runner basename `mcp_server.py` outside package root | **no** |
+| Import/launch of real entrypoint without transport bind | **no** |
+| `GITEA_MCP_SANCTIONED_DAEMON=1` alone (no process-local native runtime) | **no** (#695) |
+| `GITEA_ALLOW_DIRECT_MCP_IMPORT=1` in LLM sessions | **no** — never set; never authorizes mutations (#695 AC1 / PR #701) |
+| Override `GITEA_MCP_SESSION_STATE_DIR` mid-session | **no** — production bind pins state root; redirect cannot forge independent decision locks (#695 AC2 / PR #701) |
+| `GITEA_ALLOW_KEYCHAIN_CLI=1` in LLM sessions | **no** — human operator only |
+| bare `python -c 'import gitea_mcp_server; …'` or offline runners | **no** |
+| keychain fill outside native/pytest | **no** |
+

+## Contaminated review quarantine (#695 AC8)

+Controller/reconciler/merger profiles may call
+`gitea_quarantine_contaminated_review` with explicit confirmation:
+
+```text
+QUARANTINE CONTAMINATED REVIEW <review_id> PR <pr_number>
+```
+
+Quarantine records are durable under the MCP session-state root and are
+**honored** by:
+
+- `gitea_get_pr_review_feedback` (quarantined approvals do not authorize merge)
+- `gitea_check_pr_eligibility` action=`merge`
+- `gitea_merge_pr` (mutation)
+- merger lease adoption paths that read `approval_at_current_head`
+
+Forensic Gitea reviews and historical comments are **never deleted**.

+## STOP after native MCP failure (AC10)
+
+If the native MCP namespace dies (EOF, capability disconnect, session death):
+
+1. **STOP.** State BLOCKED + DIAGNOSE.
+2. Do **not** import `gitea_mcp_server` from a standalone process.
+3. Do **not** run `offline_mcp_helper.py`, `offline_mcp_runner.py`,
+   `run_quarantine.py`, or any offline mutation helper.
+4. Do **not** set direct-import, keychain-bypass, or raw-token environment
+   variables.
+5. Reconnect / restart the official MCP daemon; resume only via native tools.
+
+Any further native MCP failure is a hard stop. Do not construct another fallback.

+  (``GITEA_MCP_SANCTIONED_DAEMON=1`` / ``GITEA_ALLOW_DIRECT_MCP_IMPORT=1`` are

+  insufficient for mutation gates).
-- explicit operator opt-in ``GITEA_ALLOW_DIRECT_MCP_IMPORT=1`` (tests/tools only)
+- A process-local runtime record is established only by the resolved canonical
+  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.
 
-Credential keychain fill additionally allows:
+Manual deletion of session-state files is never a recovery path.

+"""#714: production first-bind pins the workspace-verified repository scope.
+
+These tests drive the real entry points (``gitea_whoami``,
+``gitea_get_runtime_context``, ``gitea_resolve_task_capability``,
+``gitea_activate_profile``) in production order. They deliberately do not
+construct a ``_SessionContext`` directly: the defect they cover is that the
+production first-bind path left ``repository``/``org`` unbound, so
+``assess_session_context`` skipped its repository/org drift checks and a
+same-host mutation against another repository was not blocked.
+
+The trusted repository identity comes from the workspace-aligned git remote
+(``Scaled-Tech-Consulting/Gitea-Tools`` for this checkout), never from
+``REMOTES`` (whose ``prgs`` default repo is ``Timesheet``) and never from a
+caller-supplied ``org``/``repo`` argument.
