Merge pull request 'feat(mcp): immutable canonical_repository_root for cross-repo namespaces (Closes #706)' (#736) from feat/issue-706-canonical-repository-root into master

Addresses REQUEST_CHANGES review 457 on PR #736.

Root cause: _trusted_session_repository derived the session org/repository
solely from _workspace_repository_slug -> _local_git_remote_url, which runs
`git remote get-url` in PROJECT_ROOT (the Gitea-Tools install checkout). A
cross-repository namespace with a configured canonical_repository_root then
pinned the Gitea-Tools identity while #274 filesystem membership bound the
external target, so _enforce_canonical_repository_root failed closed on a
self-inflicted identity mismatch and the mcp-control-plane / eagenda
namespaces stayed blocked end-to-end.

Fix: when a canonical_repository_root is configured (env over profile) and
passes existence / git-toplevel / resolvable-remote-identity validation, the
session repository slug is derived from repository_identity_slug(configured
root) instead of the install remote. The derived identity is still authorized
by the profile allowed_repositories allowlist (never self-authorizing); the
canonical filesystem root and org/repo identity remain immutable for the
session; invalid / non-git / unresolvable / unallowlisted / forged / drift
cases fail closed; unconfigured single-repo Gitea-Tools namespaces keep the
install-derived slug unchanged.

Tests: new tests/test_issue_706_f1_seed_identity_integration.py drives the
real _seed_session_context -> _enforce_canonical_repository_root path with two
real temporary git repositories (install=Gitea-Tools, configured target=
mcp-control-plane): env + profile config, reviewer + merger role kinds, and
fail-closed cases (nonexistent / non-git / unallowlisted / forged identity
drift). Reproduces the F1 block before the fix; green after.

+"""Immutable canonical repository root for cross-repository namespaces (#706).
+
+The Gitea-Tools MCP server historically derived the ``canonical_repo_root`` from
+the *install checkout* the server script lives in
+(``PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__))``). A namespace
+that runs the same server script against an *external* repository (e.g.
+``eagenda-author`` targeting ``eAgenda``) then failed every mutation: the
+branches-only / worktree-membership guards (#274) compared the task workspace
+against the Gitea-Tools ``.git`` directory, which it can never belong to.
+
+This module separates two distinct concepts:
+
+* the immutable code/install root (``PROJECT_ROOT``) — where the server lives, and
+* the namespace-scoped **canonical repository root** — the working root of the
+  repository whose issues/PRs the namespace mutates.
+
+The canonical repository root is configured per namespace (profile field or an
+environment variable, typically set alongside the namespace ``cwd`` in the MCP
+config). It is validated (existence, git identity, git common-directory
+membership) and pinned immutably into the session context so a later call cannot
+forge or swap it. When *no* binding is configured the single-repo default is
+preserved unchanged: the canonical root is derived from the process checkout.

+## 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.

+
+**Do not treat “approved” as the final readiness state.** For every approved
+open PR, call `gitea_assess_pr_sync_status` (native MCP only) and route by
+`recommended_next_action`:
+
+| Action | Meaning | Next role / tools |
+|--------|---------|-------------------|
+| `merge_now` | Valid approval at exact current head; conflict-free; update not required; checks ok | Merger: sanctioned merge workflow only — **do not** update the branch |

+### Hard rules
+
+* Pin both expected PR head and expected base head for every update. Either
+  race → fail closed with no partial mutation.
+* Never rebase or force-push author branches.
+* Never update an author branch from a reviewer or merger profile.
+* Never preserve approval, reviewer lease, merger lease, or prepared verdict
+  across a head change.
+* Process PRs **sequentially**: synchronize/remediate one → review new head →
+  merge → refresh live `master` → reassess the next PR. Do not update every
+  open PR at once (each merge restales the rest).
+* Conflict remediation only in the existing dedicated issue/PR worktree under
+  `branches/`. Do not delete that worktree until the updated PR is merged and
+  cleanup eligibility is proven.
+* Post-merge: canonical cleanup handoff to reconciler (section 28).
+
+### After `gitea_update_pr_branch_by_merge` succeeds
+
+1. Treat former-head approval as invalidated.
+2. Release/supersede obsolete reviewer and merger leases.
+3. Route `recommended_next_action=fresh_review_required` at the new head.
+4. Independent re-review, then merger lease/adopt + merge at the new head only.
+
+All Gitea reads/mutations use native MCP. Never substitute direct API, curl,
+tea/gh, Web UI mutation by an LLM, database changes, raw Git push, or token
+access.
+
 ## 27. Merge rules
 
-Before merge, rerun fresh live checks:
+Before merge, call `gitea_assess_pr_sync_status` when the PR is approved/open
+and may be behind base. Only proceed with merge when
+`recommended_next_action` is `merge_now` and approval remains at the current
+head. Then rerun fresh live checks:

 ``gitea_delete_branch`` requires the exact ``gitea.branch.delete`` operation:
 without it the delete fails closed (no preflight, no auth lookup, no API call,
-structured permission report). With it, deletion proceeds through existing
+structured permission report).
-preflight and audit unchanged.

+#729: delete_branch is reconciler-owned. ``gitea.branch.delete`` is granted only
+to the reconciler profile, so the resolver classifies delete_branch as a
+reconciler task. Raw ``gitea_delete_branch`` still redirects the reconciler to
+the guarded ``gitea_cleanup_merged_pr_branch`` path (#514/#687); author,
+reviewer, and merger remain denied by the permission gate and/or the required
+role gate.

+"""Issue #706: immutable startup/profile canonical_repository_root capability.
+
+Cross-repository MCP namespaces (e.g. ``eagenda-author``) must bind their
+canonical repository root to the *configured target repository*, not to the
+Gitea-Tools install checkout the server script lives in. These tests prove:
+
+* the configured binding is resolved from profile/env with env precedence,
+* the target repository identity and git common-directory membership are
+  validated (AC3),
+* the branches-only guard (#274) is enforced *inside the target repo* (AC4),
+* missing / conflicting / forged bindings fail closed (AC5),
+* prgs and mdcps namespaces stay simultaneously isolated (AC6),
+* the session binding pins the canonical root immutably,
+* no weakening of the install-root single-repo default (AC8).
+
+Uses two distinct real git repositories/worktrees (AC7).

+"""Issue #706 F1 integration regression (review 457).
+
+The unit tests in ``test_issue_706_canonical_repository_root.py`` exercise
+``crr.assess_canonical_repository_root`` / ``session_ctx.seed_session_context_if_unbound``
+with a *preselected* slug, so they never drive the real end-to-end path that
+review 457 found broken:
+
+    _seed_session_context -> _trusted_session_repository -> _workspace_repository_slug
+    -> _local_git_remote_url (cwd=PROJECT_ROOT, always Gitea-Tools)
+
+Before the fix, the session repository identity was pinned from the *install*
+checkout remote even when a cross-repository ``canonical_repository_root`` was
+configured to an external repository (e.g. mcp-control-plane). The mutation
+preflight then derived ``expected_slug`` from that install-derived pin and
+``_enforce_canonical_repository_root`` failed closed on a self-inflicted
+identity mismatch, so the stated cross-repo namespaces stayed blocked.
+
+These tests use two *real* temporary git repositories and drive the live
+``mcp_server._seed_session_context`` and ``mcp_server._enforce_canonical_repository_root``
+functions, asserting the session pins the *configured target* identity and that
+enforcement accepts the target worktree — while every fail-closed property is
+preserved.

+"""#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.

+"""Regression matrix for Issue #733.
+
+``gitea_delete_branch`` accepts explicit ``org``/``repo`` but historically did
+not propagate them through the anti-stomp preflight: preflight resolved the
+remote-wide ``REMOTES`` default (bare ``prgs`` → ``Scaled-Tech-Consulting/
+Timesheet``) and fail-closed with ``wrong_repo`` even though the caller
+explicitly targeted ``Scaled-Tech-Consulting/Gitea-Tools``.
+
+The fix has two parts, both exercised here:
+
+1. ``gitea_delete_branch`` forwards the explicit ``org``/``repo`` into
+   ``verify_preflight_purity`` so the shared #604 anti-stomp resolution
+   validates the *targeted* repository instead of the remote-wide default.
+2. A workspace-derived repository-binding gate
+   (``_delete_branch_repository_binding_block``) validates explicit
+   coordinates against the immutable workspace identity, rejecting wrong,
+   substituted, or unverified targets — independent of the anti-stomp
+   remote/repo guard, which by the #530 contract trusts explicit intent.
+
+Every existing gate (reconciler-only ownership; author/reviewer/merger denial;
+protected/preservation blocks) is preserved.

+"""Safe mutation-error diagnostics for the tool boundary.
+
+The #699/#701 boundary intentionally collapses every non-typed exception to an
+opaque ``internal_error`` with the class and message discarded. That makes a
+mutation failure (create_issue / create_pr / delete_branch / issue-lock)
+undiagnosable: reason_code=internal_error, retryable=false, no actionable
+detail.
+
+This suite pins the additive contract:
+
+1. For the ``internal_error`` fallback ONLY, capture a **safe exception class**
+   (a Python type identifier — never secrets) and a **strictly-redacted**
+   detail (no tokens, Authorization headers, raw URLs/hosts, absolute paths,
+   response bodies, env dumps), plus an optional ``mutation_stage`` tag.
+2. Typed classifications (auth/authz/network/config/http) are unchanged and
+   still emit fixed messages with NO detail in the daemon log.
+3. Any exception may self-declare a safe ``gitea_reason_code`` to be converted
+   into a typed structured error instead of an opaque internal_error.

+"""Regression matrix: session-bound mutation preflight resolves the workspace repo.
+
+Root-cause follow-up to #733. ``_resolve`` (the actual API-targeting resolver)
+already prefers the workspace-aligned git remote over the ``REMOTES`` default
+(bare ``prgs`` → ``Scaled-Tech-Consulting/Timesheet``). The shared #604
+anti-stomp preflight (``_run_anti_stomp_preflight``) did **not** mirror that: for
+every mutation task whose call site omitted ``org``/``repo`` it filled the
+remote-wide ``REMOTES`` default, so the #530 repo guard false-positived
+``wrong_repo`` against a ``Gitea-Tools`` checkout and blocked native
+issue/PR/review/merge/lock/cleanup mutations.
+
+The fix makes ``_run_anti_stomp_preflight`` prefer the trusted, git-remote-
+derived workspace identity for omitted coordinates on **session-bound** mutation
+tasks (marking those filled sides explicit, exactly like ``_resolve``), while
+``delete_branch`` keeps its explicit cross-repository *target* contract (#733)
+and continues to fail closed on omitted coordinates.
