Implement dynamic operation-scoped profile resolution and automatic switching when both author and reviewer profiles are configured and usable. Also support default runtime switching when multiple profiles exist without requiring allow_runtime_switching: true in rules.
Closes #228.
Implement dynamic operation-scoped profile resolution and automatic switching when both author and reviewer profiles are configured and usable. Also support default runtime switching when multiple profiles exist without requiring allow_runtime_switching: true in rules.
Verdict: request changes. The PR's own tests fail, and the one functional change is a silent security-posture regression.
1. The claimed feature is not implemented — 4 of 5 new tests fail at the PR head
The title/body say "implement dynamic operation-scoped profile resolution and automatic switching," but the only production change is the default flip in gitea_config.is_runtime_switching_enabled(). No switching logic was added to gitea_mcp_server.py (the set of is_runtime_switching_enabled consumers is unchanged from master).
Ran tests/test_operation_scoped_roles.py in a clean scratch clone at f0664f4 (project venv):
FAILED test_auto_switch_to_author — resolve_task_capability does not switch profiles
FAILED test_auto_switch_to_reviewer — same
FAILED test_mutating_actions_auto_switch — _profile_permission_block returns a block, not None
FAILED test_restart_required_when_unattached — KeyError: 'available_in_session' (field does not exist)
4 failed, 1 passed
The tests assert response fields (available_in_session, restart_required, stop_required, active_identity on the resolve result) and auto-switch side effects that exist nowhere in the codebase. Either the implementation commit was never pushed, or the tests were written against intended behavior and never run.
2. Defaulting runtime switching ON for multi-profile configs is a security regression
New behavior: any config with ≥2 profiles gets allow_runtime_switching treated as true unless explicitly set false. That silently enables gitea_activate_profile — in-session cross-role switching — for every existing author+reviewer deployment, which is exactly the standard deployment shape. This:
contradicts the gitea_activate_profile docstring left in place: "Only allowed if 'allow_runtime_switching': true is explicitly configured";
undermines the session-role-binding model this repo has been hardening (#206 wrong_role_stop with "no fallback to author mutations", #209 namespace gates, #238 sticky reviewer denial): an author-bound session could self-escalate to a profile holding gitea.pr.approve/gitea.pr.merge;
changes runtime_switching_supported and exact_safe_next_action in permission reports from "restart with the right profile" to "call gitea_activate_profile", steering LLM sessions toward the escalation path.
If #228 wants operation-scoped switching, it needs an explicit design with its own opt-in flag and gate-interaction tests (how it composes with the role router and sticky denial), not a default flip inferred from profile count. The explicit-False short-circuits added here are fine to keep.
3. Scope
test_author_continuity_dirty_worktree (the one passing test) exercises reviewer_worktree.assess_author_worktree_continuity, which is unrelated to #228 — drop or move it.
Existing suite at PR head: 916 passed, 1 failed (test_health.py::test_startup_conflict_detection — pre-existing scratch-clone portability issue, already tracked as #245/PR #248; not caused by this PR).
Requested changes
Push the actual switching implementation, or retitle/rescope the PR to what it does.
Make switching opt-in only; remove the ≥2-profiles default-True branch (keep the explicit-False short-circuits).
Make the new tests pass, and add gate-interaction coverage (role router #206, sticky denial #238) before enabling any auto-switch path.
Remove the unrelated worktree-continuity test.

1. The claimed implementation is not in the diff — the PR's own tests fail on its own head (blocking)
The title/body claim "implement operation-scoped role selection and automatic dispatch switching," but the only production change is the default flip in gitea_config.is_runtime_switching_enabled(). No auto-switch dispatch was added to gitea_resolve_task_capability or _profile_permission_block. Result on this branch:
tests/test_operation_scoped_roles.py: 5 tests → 3 FAIL, 1 ERROR
- test_auto_switch_to_reviewer: FAIL — resolve_task_capability does not switch profiles
- test_auto_switch_to_author: FAIL — same

("profile forbids 'gitea.pr.merge'") instead of switching
- test_restart_required_when_unattached: ERROR — KeyError: 'available_in_session';
resolve_task_capability does not return the #228 preflight fields
(available_in_session / restart_required / stop_required) at all
Only test_author_continuity_dirty_worktree passes, and it exercises pre-existing reviewer_worktree behavior unrelated to #228.
2. New test module leaks global state and breaks 11 existing tests in full-suite runs (blocking)
The 11 new failures outside the new file are in tests/test_permission_reports.py (6) and tests/test_pr_queue_inventory.py (5). Both modules pass in isolation on this branch and fail only when run after tests.test_operation_scoped_roles, so the new module leaks state (likely the GITEA_MCP_CONFIG tempdir config cached in gitea_config, and/or mcp_server module state not fully restored in tearDown). The setUp/tearDown resets (_IDENTITY_CACHE, _active_profile_override, _MUTATION_AUTHORITY) are not sufficient.
3. Default-enabling runtime switching for every multi-profile config weakens fail-closed posture (needs explicit decision + docs)
# Default to True if multiple profiles exist in the configprofiles=config.get("profiles")or{}iflen(profiles)>1:returnTrue
This silently turns on runtime profile switching for every existing deployment that has both author and reviewer profiles configured and deliberately left allow_runtime_switching unset (opt-in was the documented contract; see gitea_mcp_server.py:3925 gating gitea_activate_profile). Issue #228 req 4 says the change "must not allow ... using author credentials for reviewer actions" and req 3 demands one clear, tested behavior. Flipping the default may be a defensible design choice, but it needs: (a) an explicit statement in the PR, (b) the safety-invariant tests from #228 req 6 (self-review block, wrong-profile mutation blocks under switching), and (c) the controller-workflow documentation update from req 7 — none are present. Respecting explicit false (the first hunk) is good and should stay.
Verdict
The scope of #228 (operation-scoped router, preflight availability fields, auto-dispatch, docs) is not implemented here — only the switching default changed, and the tests written for the missing behavior fail. Please either implement the router/preflight surface the tests assert, or rescope the PR (and tests) to what it actually changes, and fix the test-isolation leak either way.

This silently turns on runtime profile switching for every existing deployment that has both author and reviewer profiles configured and deliberately left `allow_runtime_switching` unset (opt-in was the documented contract; see gitea_mcp_server.py:3925 gating `gitea_activate_profile`).

Validated against PR head f0664f41369b7d543c9ff568722ed71ea8a1b18f. The full suite has failures on master too, but this PR adds new failures and its own PR-owned tests fail.
Root cause:
The tests expect operation-scoped auto-switching and new capability response fields such as available_in_session, but the implementation appears to only change is_runtime_switching_enabled() to default true for multi-profile configs. That changes denial behavior without implementing the actual role/profile switch contract.
Additional concern:
The default change appears to regress existing permission report and PR queue inventory tests by changing fail-closed behavior around different_mcp_namespace_required / capability-stop paths.
Required author fix:
Implement the actual operation-scoped role-selection behavior described by the PR and tests, or narrow the tests/spec if auto-switching is not intended.
Add/return the expected response fields consistently, including available_in_session.
Preserve existing fail-closed behavior when the required namespace/profile is not attached.
Ensure author/reviewer separation remains intact.
Re-run PR-owned tests, affected permission/report tests, and the full suite.
Report master-baseline failures separately from PR-introduced failures.
Do not merge until the PR-owned tests pass and the side-effect regressions are resolved or proven pre-existing.
