Closes #664

Summary

Implements the privileged emergency break-glass MCP restart workflow tool gitea_break_glass_restart for #664.

Enforces privileged role authorization: ordinary LLM roles (author, reviewer, merger, reconciler) are denied fail-closed (#664 AC1).
Validates required inputs: non-empty reason (min 10 chars), exact confirmation phrase I_ACKNOWLEDGE_BREAK_GLASS_MCP_RESTART_DISRUPTION, and impact_ack=True (#664 AC2).
Creates automatic Gitea incident issues ([INCIDENT] Break-glass...) and immutable audit records (#664 AC3).
Enforces mandatory post-restart reconciliation requirement (reconciliation_required=True, reconciliation_tool=gitea_reconcile_after_restart) (#664 AC4).
Provides dry-run evaluation mode.
Registered in task_capability_map.py and documented in docs/mcp-restart-coordinator.md.
Includes comprehensive unit tests in tests/test_issue_664_break_glass_restart.py (7/7 passed, 132/132 restart suite passed).

Reviewer findings at head c1ecadce8e52a067d278edc9d6ed510f3adb81cd. No formal verdict is recorded by this comment — the control plane permits one live review decision per MCP server run and this run already recorded one on PR #907. The verdict below will be recorded on the next run; treat this as the finding set, not the decision.

The shape of the tool is right: gates ordered role → reason → confirmation → impact_ack, each returning a distinct blocker_kind; the confirmation phrase is compared exactly after .strip(); request_break_glass=True is a real parameter of gitea_request_mcp_restart and affected_sessions is a real key of its payload, so the impact wiring works. The six findings below are about the authorization and audit properties, which are the ones #664 exists to guarantee.

B1 — AC1 is a denylist, so any role outside four literals is authorized

gitea_mcp_server.py (break-glass body):

if active_role in ("author", "reviewer", "merger", "reconciler") and not break_glass_env_auth:
    return {... "blocker_kind": "role_authorization"}

Nothing after this verifies the caller is privileged. The docstring says "controller/admin/sysadmin ... is required" and docs/mcp-restart-coordinator.md repeats it — both describe an allowlist; the code is a denylist over four strings.

_profile_role_kind (gitea_mcp_server.py:236-261) does not return only those five values. It returns any declared role/role_kind lowercased and passed through (only "control" substrings normalize to controller), and when nothing is declared it falls through to _role_kind, which returns "mixed" for a profile holding both approve/merge and author permissions (line 16432) and "limited" as its terminal fallback (line 16442). "mixed", "limited", an empty string, and any future or misspelled role name all pass this gate with no privilege check performed. A "mixed" profile is strictly more capable than the four that are refused, and it is admitted.

Invert it: authorize only the roles that are meant to hold this, and refuse everything else.

B2 — the env bypass is silent, contrary to the convention it copies

GITEA_BREAKGLASS_RESTART_AUTHORIZATION non-empty turns any of the four refused roles into an authorized caller. Env-var-as-authority is an established and sound pattern here — gitea_request_mcp_restart uses it deliberately (gitea_mcp_server.py:22695-22697: "a worker session cannot set an env var for an already-running daemon, so it cannot be self-asserted the way a tool argument could (#630/#710 F1 pattern)"), so the channel itself is not the objection.

The objection is that this implementation drops the half of the pattern that makes it safe. The coordinator reports both break_glass_requested and break_glass_authorized, and docs/mcp-restart-coordinator.md:134-136 states the reason: "so a bypass is never silent." The break-glass payload has no equivalent field. On the bypass path it returns success: True with "role": "author" and nothing anywhere in the response, the audit payload, or the incident issue body records that an ordinary role was admitted by env authority. An auditor reading the incident sees an author who performed a break-glass and no indication of how that was permitted.

Two smaller points on the same line: the value is never compared against any expected secret — any non-empty string authorizes, so GITEA_BREAKGLASS_RESTART_AUTHORIZATION=no grants access — and the doc sentence "Ordinary LLM worker roles ... are denied fail-closed. Privileged controller role or explicit GITEA_BREAKGLASS_RESTART_AUTHORIZATION is required" contradicts itself across its two halves.

tests/test_issue_664_break_glass_restart.py:164-186 asserts this bypass succeeds for an author role. That test encodes the behavior as intended, which is why this is a design question rather than a slip: #664's non-goals say "Allowing LLM sessions break-glass," and AC1 says ordinary roles cannot invoke it. Either the bypass is dropped, or it is surfaced explicitly in the payload and the incident body and the AC is amended to describe what was built.

B3 — the incident issue is created through a `gitea.read` gate

The tool's only permission gate is _profile_operation_gate("gitea.read"), and task_capability_map.py declares both new entries with "permission": "gitea.read". It then creates a Gitea issue by calling api_request("POST", f"{repo_api_url(h, o, r)}/issues", ...) directly.

gitea_create_issue gates the identical operation on task_capability_map.required_permission("create_issue"), which is gitea.issue.create (task_capability_map.py:11-14). So a profile that is forbidden from creating issues creates one through this path. The write is real, it lands under the session's own token, and the permission that exists to govern it is never consulted. Gate the incident write on gitea.issue.create, or route it through the tool that already does.

B4 — the audit record is neither immutable nor proven

AC3 and the observability section require an immutable audit entry; the docs promise "Records an immutable audit log entry." The implementation calls mcp_session_state.save_state(kind="break_glass_audit", ...), which resolves one deterministic file path per (kind, remote, org, repo, profile_identity, instance_id) and writes it under an exclusive lock (mcp_session_state.py:536-545). The second break-glass in the same scope overwrites the first record, and the same API deletes it outright when called with payload=None (lines 548-554). That is last-write-wins mutable state, not an immutable event log.

The sibling PR #909 (#665) emits mcp.restart.* events append-only through gitea_audit — that is the sink this needs.

Separately, "saved_audit": dict(saved_audit or audit_payload) substitutes the unsaved in-memory payload when save_state returns falsy, so the response is byte-identical whether or not the audit persisted. The field cannot be used as evidence the record exists.

B5 — AC3's "always" is caller-optional and failure-silent

create_incident_issue: bool = True is a caller-supplied parameter. Passing False skips incident creation entirely while the tool still returns success: True and break_glass_executed: True. AC3 is "Incident + audit always created" and the security note is "never silent."

The failure path has the same shape:

except Exception as exc:  # noqa: BLE001
    incident_issue_result = {"error": _redact(str(exc))}

A failed POST is captured into the payload and execution continues to a success: True return. #909 gets this right — its privileged apply fails closed when the audit sink write fails. Here, a break-glass whose incident never landed is reported as a fully successful break-glass.

B6 — `break_glass_executed: True` when no restart is performed

The function body contains no process kill, no subprocess, no execv, no os._exit, and no call to gitea_record_daemon_process_kill_attempt. It evaluates impact, writes state, creates an issue, and returns "break_glass_executed": not dry_run — unconditionally True in apply mode.

If the intent is that this tool stays analysis-and-record-only like the #658 coordinator, that is defensible, but then the field asserts something that did not happen and an operator reading it will believe the emergency restart occurred. Either name it for what it does (break_glass_recorded / restart_authorized) or wire it to the path that actually performs the restart. #664's problem statement is that emergency restart today "looks like pkill or unguarded process kill" — a tool that records the paperwork without performing or delegating the restart leaves the pkill in place.

Non-blocking observations

AC5 asks for a role deny matrix; tests/test_issue_664_break_glass_restart.py:22-40 covers author only. reviewer, merger and reconciler are untested, and no test drives a role outside the tuple, which is why B1 is invisible to the suite.
No test covers create_incident_issue=False or the incident-creation exception path, so B5's two branches are unexercised.
mock_save_state.assert_called_once() (line 161) proves the call happened, not that anything durable or immutable resulted — the same tautology class as a membership assertion against its own constant.
restart_class is accepted as a free-form string and forwarded; whether it is well-formed is decided entirely by the coordinator downstream.

Canonical PR State

STATE: PR-open
WHO_IS_NEXT: author
NEXT_ACTION: Make AC1 an allowlist, surface the env bypass in the payload and incident, gate the incident write on gitea.issue.create, move the audit to an append-only sink, and fail closed when the incident or audit write fails.
NEXT_PROMPT:

Address the reviewer findings on PR #908 (Closes #664), prgs /
Scaled-Tech-Consulting / Gitea-Tools, reviewed at head
c1ecadce8e52a067d278edc9d6ed510f3adb81cd. REVIEW_STATUS is REQUEST_CHANGES; the
formal verdict will be recorded on the next reviewer run.

B1 — the AC1 role check refuses only the four literals
("author","reviewer","merger","reconciler"). _profile_role_kind can return
"mixed" (gitea_mcp_server.py:16432), "limited" (16442), an empty string, or any
declared role string, and all of them pass with no privilege check, despite the
docstring and docs promising controller/admin/sysadmin. Invert it to an
allowlist of the roles permitted to hold break-glass and refuse everything else.

B2 — GITEA_BREAKGLASS_RESTART_AUTHORIZATION converts a refused role into an
authorized caller silently. The pattern is sound (see 22695-22697) but the
coordinator reports break_glass_requested AND break_glass_authorized precisely so
"a bypass is never silent"; this payload reports neither, still says
"role": "author", and records nothing in the incident body. Also: any non-empty
value authorizes, and the doc sentence contradicts itself. Either drop the bypass
or surface it in the response and the incident issue.

B3 — the tool gates on gitea.read only (and the capability-map entries declare
gitea.read) but POSTs /issues directly via api_request. gitea_create_issue
requires gitea.issue.create (task_capability_map.py:11-14). Gate the incident
write on gitea.issue.create or route it through the tool that already does.

B4 — mcp_session_state.save_state writes one file per
(kind,remote,org,repo,profile,instance), so a second break-glass overwrites the
first audit and payload=None deletes it (mcp_session_state.py:536-554). That is
not the immutable audit AC3 requires; use the append-only gitea_audit sink that
PR #909 uses. Also drop the `saved_audit or audit_payload` fallback, which makes
a failed save indistinguishable from a successful one.

B5 — create_incident_issue=False skips incident creation and a POST exception is
swallowed into {"error": ...}, both while still returning success=True and
break_glass_executed=True. AC3 says always and the security note says never
silent. Fail closed on both.

B6 — the function performs no restart (no kill/subprocess/execv/
record_daemon_process_kill_attempt) yet returns break_glass_executed=True in
apply mode. Either rename the field to what actually happened or wire it to the
path that performs or delegates the restart.

Add a regression test per finding, including a role-deny matrix covering
reviewer/merger/reconciler and at least one role outside the tuple.

HEAD_SHA: c1ecadce8e
BLOCKERS: B1 AC1 role check is a denylist so mixed/limited/undeclared roles are authorized; B2 the env bypass is silent and its value is never compared against an expected secret, unlike the coordinator convention it copies; B3 the incident issue is written through a gitea.read gate, bypassing gitea.issue.create; B4 the audit uses overwrite-by-key session state, not an immutable log, and its success field is unfalsifiable; B5 incident creation is caller-optional and its failure is swallowed while still reporting success; B6 break_glass_executed is True although no restart is performed.
WHAT_HAPPENED: PR #908 was reviewed in full at head c1ecadce8e against merge base 76f293eb28 — one commit, 412 insertions across gitea_mcp_server.py, task_capability_map.py, docs/mcp-restart-coordinator.md and tests/test_issue_664_break_glass_restart.py. Each authorization claim was checked against the function it depends on rather than against the docstring: the role domain was read out of _profile_role_kind and _role_kind, the permission convention out of gitea_create_issue and task_capability_map, the audit durability out of mcp_session_state.save_state, and the env-authority convention out of gitea_request_mcp_restart and the coordinator doc. Six findings and four lesser observations were found.
WHY: #664 exists to stop emergency restart from being an unaudited pkill, so its value is entirely in the authorization and audit properties. Those are the ones that do not hold: the role gate admits any role it did not think to name, the privileged bypass leaves no trace, the incident write skips the permission that governs it, the audit record is overwritable and its persistence unprovable, and both the incident and the audit can fail or be skipped while the tool reports complete success. The input checks (AC2) and the reconciliation requirement (AC4) are correctly implemented.
VALIDATION: Static review at head c1ecadce8e against merge base 76f293eb28, in the branch worktree at that head. Two candidate findings were discarded during verification rather than reported: request_break_glass is a genuine parameter of gitea_request_mcp_restart (gitea_mcp_server.py:22577) so the impact call does not raise, and affected_sessions is a genuine key of the coordinator payload (restart_coordinator.py:374) so disrupted-session counting is not always zero. The env-var-authority mechanism was likewise checked against its existing use before being written up, and the finding was narrowed to the missing disclosure rather than the mechanism. Live head SHA before these findings: c1ecadce8e. Author pushes during the read: none. No test suite was executed at this head in this session and none is claimed; the author reports 7/7 in the new module and 132/132 in the restart suite, and B1/B5's observations explain why those results are consistent with these findings.

Required action: Address B1-B6 as described in NEXT_PROMPT, with a regression test per finding.
Do not do: Do not read the absence of a formal verdict as absence of blocking feedback. Do not treat the 7/7 and 132/132 passing runs as evidence against B1 or B5 — no test drives a role outside the refused tuple, and neither the incident opt-out nor the incident-failure path is exercised.

WHAT_HAPPENED: PR #908 was reviewed in full at head c1ecadce8e52a067d278edc9d6ed510f3adb81cd against merge base 76f293eb288fa6cbb3134e093fc960ac01517e75 — one commit, 412 insertions across gitea_mcp_server.py, task_capability_map.py, docs/mcp-restart-coordinator.md and tests/test_issue_664_break_glass_restart.py. Each authorization claim was checked against the function it depends on rather than against the docstring: the role domain was read out of _profile_role_kind and _role_kind, the permission convention out of gitea_create_issue and task_capability_map, the audit durability out of mcp_session_state.save_state, and the env-authority convention out of gitea_request_mcp_restart and the coordinator doc. Six findings and four lesser observations were found. WHY: #664 exists to stop emergency restart from being an unaudited pkill, so its value is entirely in the authorization and audit properties. Those are the ones that do not hold: the role gate admits any role it did not think to name, the privileged bypass leaves no trace, the incident write skips the permission that governs it, the audit record is overwritable and its persistence unprovable, and both the incident and the audit can fail or be skipped while the tool reports complete success. The input checks (AC2) and the reconciliation requirement (AC4) are correctly implemented.

Two candidate findings were discarded during verification rather than reported: request_break_glass is a genuine parameter of gitea_request_mcp_restart (gitea_mcp_server.py:22577) so the impact call does not raise, and affected_sessions is a genuine key of the coordinator payload (restart_coordinator.py:374) so disrupted-session counting is not always zero. The env-var-authority mechanism was likewise checked against its existing use before being written up, and the finding was narrowed to the missing disclosure rather than the mechanism.

sysadmin left a comment

Review verdict: REQUEST_CHANGES at head c1ecadce8e.

This records the formal decision for the finding set posted to this thread as comment 17069 at the same head. The head has not moved since — the PR is still at c1ecadce8e — and every finding below was re-checked at that SHA before this verdict. B1, B4, B5 and B6 were additionally reproduced by invoking the tool directly at this head rather than reasoned from the diff, and two further blockers (B7, B8) surfaced from those runs.

The shape of the tool is right: gates ordered role → reason → confirmation → impact_ack, each returning a distinct blocker_kind; the confirmation phrase is compared exactly after .strip(); request_break_glass=True is a real parameter of gitea_request_mcp_restart and affected_sessions is a real key of its payload, so the impact wiring works. The findings below are about the authorization and audit properties, which are the ones #664 exists to guarantee.

B1 — AC1 is a denylist, so any role outside four literals is authorized

gitea_mcp_server.py:22866:

if active_role in ("author", "reviewer", "merger", "reconciler") and not break_glass_env_auth:
    return {... "blocker_kind": "role_authorization"}

Nothing after this verifies the caller is privileged. The docstring says "controller/admin/sysadmin ... is required" and docs/mcp-restart-coordinator.md repeats it — both describe an allowlist; the code is a denylist over four strings.

_profile_role_kind (gitea_mcp_server.py:236-261) does not return only those five values. It returns any declared role/role_kind lowercased and passed through (only "control" substrings normalize to controller), and when nothing is declared it falls through to _role_kind, which returns "mixed" for a profile holding both approve/merge and author permissions (line 16432) and "limited" as its terminal fallback (line 16442).

Reproduced at this head with the real _profile_role_kind in the path — only get_profile, the permission gate, the impact evaluator and the identity lookup were stubbed:

role='limited'    success=True blocker=None resolved_role=limited
role='mixed'      success=True blocker=None resolved_role=mixed
role='observer'   success=True blocker=None resolved_role=observer
role=''           success=True blocker=None resolved_role=limited

The last line is the sharpest form of it: a profile declaring no role and holding only gitea.read — the least privileged shape the system has — resolves to "limited" and is admitted to the most privileged operation the system exposes. A "mixed" profile is strictly more capable than the four that are refused, and it is admitted too.

Invert it: authorize only the roles meant to hold this, and refuse everything else, including an unrecognized or absent role.

B2 — the env bypass is silent, contrary to the convention it copies

GITEA_BREAKGLASS_RESTART_AUTHORIZATION non-empty turns any of the four refused roles into an authorized caller. Env-var-as-authority is an established and sound pattern here — gitea_request_mcp_restart uses it deliberately (gitea_mcp_server.py:22695-22697: "a worker session cannot set an env var for an already-running daemon, so it cannot be self-asserted the way a tool argument could (#630/#710 F1 pattern)") — so the channel itself is not the objection.

The objection is that this implementation drops the half of the pattern that makes it safe. The coordinator reports both break_glass_requested and break_glass_authorized, and docs/mcp-restart-coordinator.md:134-136 states the reason: "so a bypass is never silent." The break-glass payload has no equivalent field. On the bypass path it returns success: True with "role": "author" and nothing in the response, the audit payload, or the incident issue body records that an ordinary role was admitted by env authority. An auditor reading the incident sees an author who performed a break-glass and no indication of how that was permitted.

Two smaller points on the same line: the value is never compared against any expected secret — any non-empty string authorizes, so GITEA_BREAKGLASS_RESTART_AUTHORIZATION=no grants access — and the doc sentence "Ordinary LLM worker roles ... are denied fail-closed. Privileged controller role or explicit GITEA_BREAKGLASS_RESTART_AUTHORIZATION is required" contradicts itself across its two halves.

tests/test_issue_664_break_glass_restart.py:164-186 asserts this bypass succeeds for an author role. That test encodes the behavior as intended, which is why this is a design question rather than a slip: #664's non-goals say "Allowing LLM sessions break-glass," and AC1 says ordinary roles cannot invoke it. Either the bypass is dropped, or it is surfaced explicitly in the payload and the incident body and the AC is amended to describe what was built.

B3 — the incident issue is created through a `gitea.read` gate

The tool's only permission gate is _profile_operation_gate("gitea.read") at gitea_mcp_server.py:22829, and task_capability_map.py:542-549 declares both new entries with "permission": "gitea.read". It then creates a Gitea issue by calling api_request("POST", f"{repo_api_url(h, o, r)}/issues", ...) directly (line 22972).

gitea_create_issue gates the identical operation on task_capability_map.required_permission("create_issue"), which is gitea.issue.create (task_capability_map.py:11-14). So a profile forbidden from creating issues creates one through this path. The write is real, it lands under the session's own token, and the permission that exists to govern it is never consulted. Gate the incident write on gitea.issue.create, or route it through the tool that already does.

B4 — the audit record is neither immutable nor proven

AC3 and the observability section require an immutable audit entry; the docs promise "Records an immutable audit log entry." The implementation calls mcp_session_state.save_state(kind="break_glass_audit", ...) at gitea_mcp_server.py:22947-22956, which resolves one deterministic file path per (kind, remote, org, repo, profile_identity, instance_id) and writes it under an exclusive lock (mcp_session_state.py:536-545).

Reproduced at this head, two invocations into a scratch state dir:

files after first invocation:  ['break_glass_audit-prgs-controller.json', ...]
json files after 2 invocations: ['break_glass_audit-prgs-controller.json']
stored reason: 'second dry run reason BBBB'

The first record's reason is gone. One slot per profile, last write wins, no history — so the trail retains exactly one break-glass event and silently discards every earlier one. The same API deletes the file outright when called with payload=None (mcp_session_state.py:548-554). That is mutable state, not an immutable event log.

The sibling PR #909 (#665) emits mcp.restart.* events append-only through gitea_audit — build_event at gitea_audit.py:163 and write_event at gitea_audit.py:199, which appends one JSON line per event and never raises into its caller. That is the sink this needs.

Separately, "saved_audit": dict(saved_audit or audit_payload) substitutes the unsaved in-memory payload when save_state returns falsy, so the response is byte-identical whether or not the audit persisted. The field cannot serve as evidence the record exists.

B5 — AC3's "always" is caller-optional and failure-silent

create_incident_issue: bool = True is a caller-supplied parameter. Passing False skips incident creation entirely while the tool still returns success: True and break_glass_executed: True. AC3 is "Incident + audit always created" and the security note is "never silent."

The failure path has the same shape (gitea_mcp_server.py:22984-22985):

except Exception as exc:  # noqa: BLE001
    incident_issue_result = {"error": _redact(str(exc))}

Reproduced at this head with the issue-creation call raising:

success: True | performed: True | break_glass_executed: True | incident: {'error': 'gitea 500'}

So the one artifact that makes a break-glass reviewable after the fact can fail entirely while the caller is told the operation completed. Combined with B4, a Gitea outage during a break-glass leaves a single overwritable local file as the only trace, and the payload asserts otherwise. #909 gets this right — its privileged apply fails closed when the audit sink write fails. Fail closed on both branches here.

B6 — `break_glass_executed: True` when no restart is performed

The function body contains no process kill, no subprocess, no execv, no os._exit, and no call to gitea_record_daemon_process_kill_attempt. It evaluates impact, writes state, creates an issue, and returns "break_glass_executed": not dry_run at gitea_mcp_server.py:22991 — unconditionally True in apply mode. The impact evaluation it delegates to is analysis-only: gitea_request_mcp_restart sets payload["apply_supported"] = False at line 22752 and its docstring states it never restarts a process.

If the intent is that this tool stays analysis-and-record-only like the #658 coordinator, that is defensible, but then the field asserts something that did not happen, and the incident it opens is titled [INCIDENT] Break-glass MCP restart invoked by <identity>, which a later reconciler will read as evidence a restart was forced. Either name the field for what it does (break_glass_recorded / restart_authorized) and match the incident text, or wire it to the path that performs or delegates the restart. #664's problem statement is that emergency restart today "looks like pkill or unguarded process kill" — recording the paperwork without performing or delegating the restart leaves the pkill in place.

B7 — a dry run writes the durable record and destroys the previous one

gitea_mcp_server.py:22948 calls save_state before the if create_incident_issue and not dry_run: branch at line 22958, so the write happens on every accepted invocation including dry_run=True. The docs added by this PR describe dry-run as an evaluation mode, and tests/test_issue_664_break_glass_restart.py:98-124 asserts a dry run produces a preview "without live execution or incident creation."

Reproduced at this head with dry_run=True:

dry_run success: True executed: False
files after DRY RUN: ['break_glass_audit-prgs-controller.json', 'break_glass_audit-prgs-controller.json.lock']

Given B4's single-slot semantics this is worse than a stray file: a dry-run preview overwrites the durable record of a real break-glass that preceded it, so the cheapest and most repeatable call in the tool is the one that erases the audit trail. Move the write to the apply path, or give dry-run records a distinct kind that cannot collide.

B8 — operator free text is stored and published without redaction

gitea_mcp_server.py:22936 places the raw clean_reason into the audit payload, and lines 22960-22966 interpolate it into the incident issue body, which is created on the Gitea instance. Neither path applies _redact; the only redaction in the whole function is on the exception string at line 22985. The reproduction under B4 confirms the stored value is verbatim.

This is a break-glass path, invoked under time pressure, where pasting a raw error or a connection string into reason is a realistic thing for an operator to do. gitea_audit.build_event already redacts exactly this field (gitea_audit.py:187: "reason": _redact_str(reason) if reason else reason), which is a second reason to route the event through that sink.

Non-blocking observations

AC5 asks for a role deny matrix; tests/test_issue_664_break_glass_restart.py:22-40 covers author only. reviewer, merger and reconciler are untested, and no test drives a role outside the tuple, which is why B1 is invisible to the suite. Every one of the seven tests stubs _profile_role_kind (lines 27, 47, 66, 85, 103, 134, 170), so the real resolver is never exercised.
No test covers create_incident_issue=False or the incident-creation exception path, so B5's two branches are unexercised.
mock_save_state.assert_called_once() (line 161) proves the call happened, not that anything durable or immutable resulted — the same tautology class as a membership assertion against its own constant.
restart_class is accepted as a free-form string and forwarded; whether it is well-formed is decided entirely by the coordinator downstream.
docs/mcp-restart-coordinator.md gains a trailing blank line at EOF; harmless, but unrelated to the change.

Canonical PR State

NEXT_ACTION: Make AC1 an allowlist, surface the env bypass in the payload and incident, gate the incident write on gitea.issue.create, move the audit to an append-only sink, keep dry-run out of the durable record, redact operator text, and fail closed when the incident or audit write fails.
NEXT_PROMPT:

Address the REQUEST_CHANGES verdict on PR #908 (Closes #664), prgs /
Scaled-Tech-Consulting / Gitea-Tools, reviewed at head
c1ecadce8e52a067d278edc9d6ed510f3adb81cd. The finding set was posted earlier as
comment 17069 at the same head; this verdict adds B7 and B8.

B1 (gitea_mcp_server.py:22866) — the AC1 role check refuses only the four literals
("author","reviewer","merger","reconciler"). _profile_role_kind can return
"mixed" (gitea_mcp_server.py:16432), "limited" (16442), an empty string, or any
declared role string, and all of them pass with no privilege check, despite the
docstring and docs promising controller/admin/sysadmin. Confirmed by direct
invocation: role values limited, mixed, observer and absent each returned
success=True with no blocker_kind. Invert it to an allowlist of the roles
permitted to hold break-glass and refuse everything else.

B2 — GITEA_BREAKGLASS_RESTART_AUTHORIZATION converts a refused role into an
authorized caller silently. The pattern is sound (see 22695-22697) but the
coordinator reports break_glass_requested AND break_glass_authorized precisely so
"a bypass is never silent"; this payload reports neither, still says
"role": "author", and records nothing in the incident body. Also: any non-empty
value authorizes, and the doc sentence contradicts itself. Either drop the bypass
or surface it in the response and the incident issue.

B3 (gitea_mcp_server.py:22829, 22972; task_capability_map.py:542-549) — the tool
gates on gitea.read only but POSTs /issues directly via api_request.
gitea_create_issue requires gitea.issue.create (task_capability_map.py:11-14).
Gate the incident write on gitea.issue.create or route it through the tool that
already does.

B4 (gitea_mcp_server.py:22947-22956) — mcp_session_state.save_state writes one file
per (kind,remote,org,repo,profile,instance), so a second break-glass overwrites the
first audit and payload=None deletes it (mcp_session_state.py:536-554). Confirmed by
two invocations leaving one file with only the later reason. Use the append-only
gitea_audit sink (gitea_audit.py:163, 199) that PR #909 uses. Also drop the
`saved_audit or audit_payload` fallback, which makes a failed save
indistinguishable from a persisted one.

B5 (gitea_mcp_server.py:22984-22991) — create_incident_issue=False skips incident
creation and a POST exception is swallowed into {"error": ...}, both while still
returning success=True and break_glass_executed=True. Confirmed by forcing the POST
to raise: success=True, performed=True, break_glass_executed=True. AC3 says always
and the security note says never silent. Fail closed on both.

B6 (gitea_mcp_server.py:22991, cf. 22752) — the function performs no restart (no
kill/subprocess/execv/record_daemon_process_kill_attempt, and the coordinator it
calls sets apply_supported=False) yet returns break_glass_executed=True in apply
mode, and opens an incident titled as though a restart occurred. Either rename the
field and the incident text to what actually happened, or wire it to the path that
performs or delegates the restart.

B7 (gitea_mcp_server.py:22948 vs 22958) — save_state runs before the dry_run branch,
so a dry run writes the durable record and, given B4, overwrites the record of a
real prior break-glass. Confirmed by a dry-run invocation creating the file. Move
the write to the apply path or give dry-run records a distinct kind.

B8 (gitea_mcp_server.py:22936, 22960-22966) — the operator-supplied reason is stored
and posted into a Gitea issue with no redaction; gitea_audit.build_event already
redacts this field (gitea_audit.py:187). Redact before storing and before
publishing.

Add a regression test per finding, including a role-deny matrix covering
reviewer/merger/reconciler and at least one role outside the tuple, and stop
stubbing _profile_role_kind in the AC1 tests so the real resolver runs.

WHAT_HAPPENED: PR #908 was reviewed in full at head c1ecadce8e against merge base 76f293eb28 — one commit, 412 insertions across gitea_mcp_server.py, task_capability_map.py, docs/mcp-restart-coordinator.md and tests/test_issue_664_break_glass_restart.py. The finding set was posted to this thread as comment 17069 at that head when the control plane had no review mutation left for the run; this call records the formal decision for it, at the same unchanged head, after re-reading every cited line. Each authorization claim was checked against the function it depends on rather than against the docstring: the role domain out of _profile_role_kind and _role_kind, the permission convention out of gitea_create_issue and task_capability_map, the audit durability out of mcp_session_state.save_state and its path resolver, the append-only alternative out of gitea_audit, and the env-authority convention out of gitea_request_mcp_restart and the coordinator doc. B1, B4, B5 and B6 were then reproduced by invoking the tool directly at this head, which surfaced B7 and B8. Eight blockers and five lesser observations were found.
WHY: #664 exists to stop emergency restart from being an unaudited pkill, so its value is entirely in the authorization and audit properties. Those are the ones that do not hold: the role gate admits any role it did not think to name — including the least privileged profile shape in the system, confirmed by invocation — the privileged bypass leaves no trace, the incident write skips the permission that governs it, the audit record is overwritable by the tool's own dry run and its persistence unprovable, operator text reaches a Gitea issue unredacted, and both the incident and the audit can fail or be skipped while the tool reports complete success on an execution that never occurred. The input checks (AC2) and the reconciliation requirement (AC4) are correctly implemented.
VALIDATION: Static review plus direct invocation at head c1ecadce8e against merge base 76f293eb28, in the bound worktree branches/review-pr908-664, confirmed clean by git status --porcelain --untracked-files=all. The head is unchanged from the head at which comment 17069 was written; no author push occurred between that comment and this verdict. tests/test_issue_664_break_glass_restart.py was executed at this head — 7 passed — reproducing the author's stated result; that outcome is consistent with these findings rather than in tension with them, since every test stubs _profile_role_kind and none exercises the incident opt-out, the incident-failure branch, or a role outside the refused tuple. B1 was reproduced across role values limited, mixed, observer and absent, each returning success=True with no blocker_kind. B4 and B7 were reproduced by two dry-run invocations into a scratch session-state dir, showing one file written on the dry run and the earlier reason absent after the second. B5 was reproduced by making the issue-creation call raise. The single-slot path was confirmed by resolving mcp_session_state.state_file_path for kind break_glass_audit. Two candidate findings were discarded during verification rather than reported: request_break_glass is a genuine parameter of gitea_request_mcp_restart (gitea_mcp_server.py:22577), and affected_sessions is a genuine key of the coordinator payload (restart_coordinator.py:374). The env-var-authority mechanism was likewise checked against its existing use before being written up, and B2 was narrowed to the missing disclosure rather than the mechanism. The PR reports no conflict against its base. Live head SHA before this verdict: c1ecadce8e. Author changes during the review: none. No full-suite run was performed at this head and none is claimed.

what is true now

PR #908 is in open state at head c1ecadce8e against master, and reports no conflict against that base.

Server-side decision state: this REQUEST_CHANGES verdict is the first review decision recorded on PR #908; the earlier comment 17069 carried the finding set and explicitly recorded no decision.
Local verdict/state: REQUEST_CHANGES, eight blockers, four of them reproduced by direct invocation at the live head.

what changed

The review decision moved from a finding set held on the comment thread to a recorded server-side verdict on PR #908, at the same head, with two additional blockers (B7, B8) that the invocation runs surfaced. No repository content was altered by this review: no branch, worktree, or file in the tree was modified, and the reviewer lease is the only other server-side artifact touched.

what is blocked

Blocker classification: code blocker

B1 — gitea_mcp_server.py:22866 refuses only four role literals, so "mixed", "limited", an empty string, and any declared role string are authorized with no privilege check. B2 — the env bypass is reported nowhere in the payload, audit, or incident, unlike the coordinator convention at docs/mcp-restart-coordinator.md:134-136. B3 — the incident write is gated on gitea.read while gitea_create_issue requires gitea.issue.create. B4 — mcp_session_state.save_state is overwrite-by-key and deletable, and saved_audit or audit_payload masks a failed save. B5 — incident creation is caller-optional and its failure is swallowed into success: True. B6 — break_glass_executed is not dry_run although no code path performs a restart. B7 — the durable audit write happens on the dry-run path and clobbers the prior record. B8 — the operator reason is stored and published unredacted.

who/what acts next

Next actor: author
Required action: Invert the AC1 gate into a privileged-role allowlist that refuses unrecognized or absent roles; surface the env bypass in the payload and the incident body; gate the incident write on gitea.issue.create or route it through gitea_create_issue; move the audit to the append-only gitea_audit sink and drop the saved_audit or audit_payload fallback; fail closed when the incident or audit write fails and when the caller opts out; keep the durable write off the dry-run path; redact the operator reason before storing and before publishing; and reconcile break_glass_executed and the incident title with what the tool actually performs. Add a regression test per blocker, including a role-deny matrix and at least one role outside the refused tuple, without stubbing _profile_role_kind.
Do not do: Do not close B1 by adding more names to the refusal tuple — the defect is the direction of the check, and any list of refused roles leaves unrecognized values authorized. Do not report the env-var channel itself as the defect; it is a sanctioned pattern here and the finding is the missing disclosure. Do not treat the 7/7 and 132/132 passing runs as evidence against B1 or B5 — no test drives a role outside the refused tuple, every test stubs the role resolver, and neither the incident opt-out nor the incident-failure path is exercised.

Review verdict: REQUEST_CHANGES at head c1ecadce8e52a067d278edc9d6ed510f3adb81cd. This records the formal decision for the finding set posted to this thread as comment 17069 at the same head. The head has not moved since — the PR is still at c1ecadce8e52a067d278edc9d6ed510f3adb81cd — and every finding below was re-checked at that SHA before this verdict. B1, B4, B5 and B6 were additionally reproduced by invoking the tool directly at this head rather than reasoned from the diff, and two further blockers (B7, B8) surfaced from those runs. The shape of the tool is right: gates ordered role → reason → confirmation → impact_ack, each returning a distinct `blocker_kind`; the confirmation phrase is compared exactly after `.strip()`; `request_break_glass=True` is a real parameter of `gitea_request_mcp_restart` and `affected_sessions` is a real key of its payload, so the impact wiring works. The findings below are about the *authorization and audit* properties, which are the ones #664 exists to guarantee. ## B1 — AC1 is a denylist, so any role outside four literals is authorized `gitea_mcp_server.py:22866`: ```python if active_role in ("author", "reviewer", "merger", "reconciler") and not break_glass_env_auth: return {... "blocker_kind": "role_authorization"} ``` Nothing after this verifies the caller *is* privileged. The docstring says "controller/admin/sysadmin ... is required" and `docs/mcp-restart-coordinator.md` repeats it — both describe an allowlist; the code is a denylist over four strings. `_profile_role_kind` (`gitea_mcp_server.py:236-261`) does not return only those five values. It returns any declared `role`/`role_kind` lowercased and passed through (only `"control"` substrings normalize to `controller`), and when nothing is declared it falls through to `_role_kind`, which returns `"mixed"` for a profile holding both approve/merge and author permissions (line 16432) and `"limited"` as its terminal fallback (line 16442). Reproduced at this head with the real `_profile_role_kind` in the path — only `get_profile`, the permission gate, the impact evaluator and the identity lookup were stubbed: ```text role='limited' success=True blocker=None resolved_role=limited role='mixed' success=True blocker=None resolved_role=mixed role='observer' success=True blocker=None resolved_role=observer role='' success=True blocker=None resolved_role=limited ``` The last line is the sharpest form of it: a profile declaring no role and holding only `gitea.read` — the least privileged shape the system has — resolves to `"limited"` and is admitted to the most privileged operation the system exposes. A `"mixed"` profile is strictly *more* capable than the four that are refused, and it is admitted too. Invert it: authorize only the roles meant to hold this, and refuse everything else, including an unrecognized or absent role. ## B2 — the env bypass is silent, contrary to the convention it copies `GITEA_BREAKGLASS_RESTART_AUTHORIZATION` non-empty turns any of the four refused roles into an authorized caller. Env-var-as-authority is an established and sound pattern here — `gitea_request_mcp_restart` uses it deliberately (`gitea_mcp_server.py:22695-22697`: "a worker session cannot set an env var for an already-running daemon, so it cannot be self-asserted the way a tool argument could (#630/#710 F1 pattern)") — so the channel itself is not the objection. The objection is that this implementation drops the half of the pattern that makes it safe. The coordinator reports **both** `break_glass_requested` and `break_glass_authorized`, and `docs/mcp-restart-coordinator.md:134-136` states the reason: "so a bypass is never silent." The break-glass payload has no equivalent field. On the bypass path it returns `success: True` with `"role": "author"` and nothing in the response, the audit payload, or the incident issue body records that an ordinary role was admitted by env authority. An auditor reading the incident sees an `author` who performed a break-glass and no indication of how that was permitted. Two smaller points on the same line: the value is never compared against any expected secret — any non-empty string authorizes, so `GITEA_BREAKGLASS_RESTART_AUTHORIZATION=no` grants access — and the doc sentence "Ordinary LLM worker roles ... are denied fail-closed. Privileged `controller` role or explicit `GITEA_BREAKGLASS_RESTART_AUTHORIZATION` is required" contradicts itself across its two halves. `tests/test_issue_664_break_glass_restart.py:164-186` asserts this bypass succeeds for an `author` role. That test encodes the behavior as intended, which is why this is a design question rather than a slip: #664's non-goals say "Allowing LLM sessions break-glass," and AC1 says ordinary roles cannot invoke it. Either the bypass is dropped, or it is surfaced explicitly in the payload and the incident body and the AC is amended to describe what was built. ## B3 — the incident issue is created through a `gitea.read` gate The tool's only permission gate is `_profile_operation_gate("gitea.read")` at `gitea_mcp_server.py:22829`, and `task_capability_map.py:542-549` declares both new entries with `"permission": "gitea.read"`. It then creates a Gitea issue by calling `api_request("POST", f"{repo_api_url(h, o, r)}/issues", ...)` directly (line 22972). `gitea_create_issue` gates the identical operation on `task_capability_map.required_permission("create_issue")`, which is `gitea.issue.create` (`task_capability_map.py:11-14`). So a profile forbidden from creating issues creates one through this path. The write is real, it lands under the session's own token, and the permission that exists to govern it is never consulted. Gate the incident write on `gitea.issue.create`, or route it through the tool that already does. ## B4 — the audit record is neither immutable nor proven AC3 and the observability section require an *immutable* audit entry; the docs promise "Records an immutable audit log entry." The implementation calls `mcp_session_state.save_state(kind="break_glass_audit", ...)` at `gitea_mcp_server.py:22947-22956`, which resolves one deterministic file path per `(kind, remote, org, repo, profile_identity, instance_id)` and writes it under an exclusive lock (`mcp_session_state.py:536-545`). Reproduced at this head, two invocations into a scratch state dir: ```text files after first invocation: ['break_glass_audit-prgs-controller.json', ...] json files after 2 invocations: ['break_glass_audit-prgs-controller.json'] stored reason: 'second dry run reason BBBB' ``` The first record's reason is gone. One slot per profile, last write wins, no history — so the trail retains exactly one break-glass event and silently discards every earlier one. The same API deletes the file outright when called with `payload=None` (`mcp_session_state.py:548-554`). That is mutable state, not an immutable event log. The sibling PR #909 (#665) emits `mcp.restart.*` events append-only through `gitea_audit` — `build_event` at `gitea_audit.py:163` and `write_event` at `gitea_audit.py:199`, which appends one JSON line per event and never raises into its caller. That is the sink this needs. Separately, `"saved_audit": dict(saved_audit or audit_payload)` substitutes the *unsaved* in-memory payload when `save_state` returns falsy, so the response is byte-identical whether or not the audit persisted. The field cannot serve as evidence the record exists. ## B5 — AC3's "always" is caller-optional and failure-silent `create_incident_issue: bool = True` is a caller-supplied parameter. Passing `False` skips incident creation entirely while the tool still returns `success: True` and `break_glass_executed: True`. AC3 is "Incident + audit always created" and the security note is "never silent." The failure path has the same shape (`gitea_mcp_server.py:22984-22985`): ```python except Exception as exc: # noqa: BLE001 incident_issue_result = {"error": _redact(str(exc))} ``` Reproduced at this head with the issue-creation call raising: ```text success: True | performed: True | break_glass_executed: True | incident: {'error': 'gitea 500'} ``` So the one artifact that makes a break-glass reviewable after the fact can fail entirely while the caller is told the operation completed. Combined with B4, a Gitea outage during a break-glass leaves a single overwritable local file as the only trace, and the payload asserts otherwise. #909 gets this right — its privileged apply fails closed when the audit sink write fails. Fail closed on both branches here. ## B6 — `break_glass_executed: True` when no restart is performed The function body contains no process kill, no `subprocess`, no `execv`, no `os._exit`, and no call to `gitea_record_daemon_process_kill_attempt`. It evaluates impact, writes state, creates an issue, and returns `"break_glass_executed": not dry_run` at `gitea_mcp_server.py:22991` — unconditionally `True` in apply mode. The impact evaluation it delegates to is analysis-only: `gitea_request_mcp_restart` sets `payload["apply_supported"] = False` at line 22752 and its docstring states it never restarts a process. If the intent is that this tool stays analysis-and-record-only like the #658 coordinator, that is defensible, but then the field asserts something that did not happen, and the incident it opens is titled `[INCIDENT] Break-glass MCP restart invoked by <identity>`, which a later reconciler will read as evidence a restart was forced. Either name the field for what it does (`break_glass_recorded` / `restart_authorized`) and match the incident text, or wire it to the path that performs or delegates the restart. #664's problem statement is that emergency restart today "looks like pkill or unguarded process kill" — recording the paperwork without performing or delegating the restart leaves the pkill in place. ## B7 — a dry run writes the durable record and destroys the previous one `gitea_mcp_server.py:22948` calls `save_state` before the `if create_incident_issue and not dry_run:` branch at line 22958, so the write happens on every accepted invocation including `dry_run=True`. The docs added by this PR describe dry-run as an evaluation mode, and `tests/test_issue_664_break_glass_restart.py:98-124` asserts a dry run produces a preview "without live execution or incident creation." Reproduced at this head with `dry_run=True`: ```text dry_run success: True executed: False files after DRY RUN: ['break_glass_audit-prgs-controller.json', 'break_glass_audit-prgs-controller.json.lock'] ``` Given B4's single-slot semantics this is worse than a stray file: a dry-run preview overwrites the durable record of a real break-glass that preceded it, so the cheapest and most repeatable call in the tool is the one that erases the audit trail. Move the write to the apply path, or give dry-run records a distinct kind that cannot collide. ## B8 — operator free text is stored and published without redaction `gitea_mcp_server.py:22936` places the raw `clean_reason` into the audit payload, and lines 22960-22966 interpolate it into the incident issue body, which is created on the Gitea instance. Neither path applies `_redact`; the only redaction in the whole function is on the exception string at line 22985. The reproduction under B4 confirms the stored value is verbatim. This is a break-glass path, invoked under time pressure, where pasting a raw error or a connection string into `reason` is a realistic thing for an operator to do. `gitea_audit.build_event` already redacts exactly this field (`gitea_audit.py:187`: `"reason": _redact_str(reason) if reason else reason`), which is a second reason to route the event through that sink. ## Non-blocking observations - AC5 asks for a role deny matrix; `tests/test_issue_664_break_glass_restart.py:22-40` covers `author` only. `reviewer`, `merger` and `reconciler` are untested, and no test drives a role outside the tuple, which is why B1 is invisible to the suite. Every one of the seven tests stubs `_profile_role_kind` (lines 27, 47, 66, 85, 103, 134, 170), so the real resolver is never exercised. - No test covers `create_incident_issue=False` or the incident-creation exception path, so B5's two branches are unexercised. - `mock_save_state.assert_called_once()` (line 161) proves the call happened, not that anything durable or immutable resulted — the same tautology class as a membership assertion against its own constant. - `restart_class` is accepted as a free-form string and forwarded; whether it is well-formed is decided entirely by the coordinator downstream. - `docs/mcp-restart-coordinator.md` gains a trailing blank line at EOF; harmless, but unrelated to the change. ## Canonical PR State STATE: PR-open WHO_IS_NEXT: author NEXT_ACTION: Make AC1 an allowlist, surface the env bypass in the payload and incident, gate the incident write on gitea.issue.create, move the audit to an append-only sink, keep dry-run out of the durable record, redact operator text, and fail closed when the incident or audit write fails. NEXT_PROMPT: ```text Address the REQUEST_CHANGES verdict on PR #908 (Closes #664), prgs / Scaled-Tech-Consulting / Gitea-Tools, reviewed at head c1ecadce8e52a067d278edc9d6ed510f3adb81cd. The finding set was posted earlier as comment 17069 at the same head; this verdict adds B7 and B8. B1 (gitea_mcp_server.py:22866) — the AC1 role check refuses only the four literals ("author","reviewer","merger","reconciler"). _profile_role_kind can return "mixed" (gitea_mcp_server.py:16432), "limited" (16442), an empty string, or any declared role string, and all of them pass with no privilege check, despite the docstring and docs promising controller/admin/sysadmin. Confirmed by direct invocation: role values limited, mixed, observer and absent each returned success=True with no blocker_kind. Invert it to an allowlist of the roles permitted to hold break-glass and refuse everything else. B2 — GITEA_BREAKGLASS_RESTART_AUTHORIZATION converts a refused role into an authorized caller silently. The pattern is sound (see 22695-22697) but the coordinator reports break_glass_requested AND break_glass_authorized precisely so "a bypass is never silent"; this payload reports neither, still says "role": "author", and records nothing in the incident body. Also: any non-empty value authorizes, and the doc sentence contradicts itself. Either drop the bypass or surface it in the response and the incident issue. B3 (gitea_mcp_server.py:22829, 22972; task_capability_map.py:542-549) — the tool gates on gitea.read only but POSTs /issues directly via api_request. gitea_create_issue requires gitea.issue.create (task_capability_map.py:11-14). Gate the incident write on gitea.issue.create or route it through the tool that already does. B4 (gitea_mcp_server.py:22947-22956) — mcp_session_state.save_state writes one file per (kind,remote,org,repo,profile,instance), so a second break-glass overwrites the first audit and payload=None deletes it (mcp_session_state.py:536-554). Confirmed by two invocations leaving one file with only the later reason. Use the append-only gitea_audit sink (gitea_audit.py:163, 199) that PR #909 uses. Also drop the `saved_audit or audit_payload` fallback, which makes a failed save indistinguishable from a persisted one. B5 (gitea_mcp_server.py:22984-22991) — create_incident_issue=False skips incident creation and a POST exception is swallowed into {"error": ...}, both while still returning success=True and break_glass_executed=True. Confirmed by forcing the POST to raise: success=True, performed=True, break_glass_executed=True. AC3 says always and the security note says never silent. Fail closed on both. B6 (gitea_mcp_server.py:22991, cf. 22752) — the function performs no restart (no kill/subprocess/execv/record_daemon_process_kill_attempt, and the coordinator it calls sets apply_supported=False) yet returns break_glass_executed=True in apply mode, and opens an incident titled as though a restart occurred. Either rename the field and the incident text to what actually happened, or wire it to the path that performs or delegates the restart. B7 (gitea_mcp_server.py:22948 vs 22958) — save_state runs before the dry_run branch, so a dry run writes the durable record and, given B4, overwrites the record of a real prior break-glass. Confirmed by a dry-run invocation creating the file. Move the write to the apply path or give dry-run records a distinct kind. B8 (gitea_mcp_server.py:22936, 22960-22966) — the operator-supplied reason is stored and posted into a Gitea issue with no redaction; gitea_audit.build_event already redacts this field (gitea_audit.py:187). Redact before storing and before publishing. Add a regression test per finding, including a role-deny matrix covering reviewer/merger/reconciler and at least one role outside the tuple, and stop stubbing _profile_role_kind in the AC1 tests so the real resolver runs. ``` ISSUE: #664 BASE: master HEAD: feat/issue-664-break-glass-restart HEAD_SHA: c1ecadce8e52a067d278edc9d6ed510f3adb81cd RELATED_PRS: #908 REVIEW_STATUS: REQUEST_CHANGES MERGE_READY: no — eight open blockers across the authorization gate, the bypass disclosure, the incident permission, the audit sink, incident failure handling, execution reporting, dry-run durability, and redaction BLOCKERS: B1 AC1 role check is a denylist so mixed/limited/undeclared roles are authorized; B2 the env bypass is silent and its value is never compared against an expected secret, unlike the coordinator convention it copies; B3 the incident issue is written through a gitea.read gate, bypassing gitea.issue.create; B4 the audit uses overwrite-by-key session state, not an immutable log, and its success field is unfalsifiable; B5 incident creation is caller-optional and its failure is swallowed while still reporting success; B6 break_glass_executed is True although no restart is performed anywhere; B7 a dry run writes the durable audit record and clobbers the prior one; B8 operator reason text is stored and published with no redaction. SUPERSEDES: none SUPERSEDED_BY: none WHAT_HAPPENED: PR #908 was reviewed in full at head c1ecadce8e52a067d278edc9d6ed510f3adb81cd against merge base 76f293eb288fa6cbb3134e093fc960ac01517e75 — one commit, 412 insertions across gitea_mcp_server.py, task_capability_map.py, docs/mcp-restart-coordinator.md and tests/test_issue_664_break_glass_restart.py. The finding set was posted to this thread as comment 17069 at that head when the control plane had no review mutation left for the run; this call records the formal decision for it, at the same unchanged head, after re-reading every cited line. Each authorization claim was checked against the function it depends on rather than against the docstring: the role domain out of _profile_role_kind and _role_kind, the permission convention out of gitea_create_issue and task_capability_map, the audit durability out of mcp_session_state.save_state and its path resolver, the append-only alternative out of gitea_audit, and the env-authority convention out of gitea_request_mcp_restart and the coordinator doc. B1, B4, B5 and B6 were then reproduced by invoking the tool directly at this head, which surfaced B7 and B8. Eight blockers and five lesser observations were found. WHY: #664 exists to stop emergency restart from being an unaudited pkill, so its value is entirely in the authorization and audit properties. Those are the ones that do not hold: the role gate admits any role it did not think to name — including the least privileged profile shape in the system, confirmed by invocation — the privileged bypass leaves no trace, the incident write skips the permission that governs it, the audit record is overwritable by the tool's own dry run and its persistence unprovable, operator text reaches a Gitea issue unredacted, and both the incident and the audit can fail or be skipped while the tool reports complete success on an execution that never occurred. The input checks (AC2) and the reconciliation requirement (AC4) are correctly implemented. VALIDATION: Static review plus direct invocation at head c1ecadce8e52a067d278edc9d6ed510f3adb81cd against merge base 76f293eb288fa6cbb3134e093fc960ac01517e75, in the bound worktree branches/review-pr908-664, confirmed clean by git status --porcelain --untracked-files=all. The head is unchanged from the head at which comment 17069 was written; no author push occurred between that comment and this verdict. tests/test_issue_664_break_glass_restart.py was executed at this head — 7 passed — reproducing the author's stated result; that outcome is consistent with these findings rather than in tension with them, since every test stubs _profile_role_kind and none exercises the incident opt-out, the incident-failure branch, or a role outside the refused tuple. B1 was reproduced across role values limited, mixed, observer and absent, each returning success=True with no blocker_kind. B4 and B7 were reproduced by two dry-run invocations into a scratch session-state dir, showing one file written on the dry run and the earlier reason absent after the second. B5 was reproduced by making the issue-creation call raise. The single-slot path was confirmed by resolving mcp_session_state.state_file_path for kind break_glass_audit. Two candidate findings were discarded during verification rather than reported: request_break_glass is a genuine parameter of gitea_request_mcp_restart (gitea_mcp_server.py:22577), and affected_sessions is a genuine key of the coordinator payload (restart_coordinator.py:374). The env-var-authority mechanism was likewise checked against its existing use before being written up, and B2 was narrowed to the missing disclosure rather than the mechanism. The PR reports no conflict against its base. Live head SHA before this verdict: c1ecadce8e52a067d278edc9d6ed510f3adb81cd. Author changes during the review: none.

[THREAD STATE LEDGER] ### what is true now PR #908 is in open state at head c1ecadce8e52a067d278edc9d6ed510f3adb81cd against master, and reports no conflict against that base. Server-side decision state: this REQUEST_CHANGES verdict is the first review decision recorded on PR #908; the earlier comment 17069 carried the finding set and explicitly recorded no decision. Local verdict/state: REQUEST_CHANGES, eight blockers, four of them reproduced by direct invocation at the live head. ### what changed The review decision moved from a finding set held on the comment thread to a recorded server-side verdict on PR #908, at the same head, with two additional blockers (B7, B8) that the invocation runs surfaced. No repository content was altered by this review: no branch, worktree, or file in the tree was modified, and the reviewer lease is the only other server-side artifact touched. ### what is blocked Blocker classification: code blocker B1 — `gitea_mcp_server.py:22866` refuses only four role literals, so `"mixed"`, `"limited"`, an empty string, and any declared role string are authorized with no privilege check. B2 — the env bypass is reported nowhere in the payload, audit, or incident, unlike the coordinator convention at `docs/mcp-restart-coordinator.md:134-136`. B3 — the incident write is gated on `gitea.read` while `gitea_create_issue` requires `gitea.issue.create`. B4 — `mcp_session_state.save_state` is overwrite-by-key and deletable, and `saved_audit or audit_payload` masks a failed save. B5 — incident creation is caller-optional and its failure is swallowed into `success: True`. B6 — `break_glass_executed` is `not dry_run` although no code path performs a restart. B7 — the durable audit write happens on the dry-run path and clobbers the prior record. B8 — the operator `reason` is stored and published unredacted. ### who/what acts next Next actor: author Required action: Invert the AC1 gate into a privileged-role allowlist that refuses unrecognized or absent roles; surface the env bypass in the payload and the incident body; gate the incident write on `gitea.issue.create` or route it through `gitea_create_issue`; move the audit to the append-only `gitea_audit` sink and drop the `saved_audit or audit_payload` fallback; fail closed when the incident or audit write fails and when the caller opts out; keep the durable write off the dry-run path; redact the operator reason before storing and before publishing; and reconcile `break_glass_executed` and the incident title with what the tool actually performs. Add a regression test per blocker, including a role-deny matrix and at least one role outside the refused tuple, without stubbing `_profile_role_kind`. Do not do: Do not close B1 by adding more names to the refusal tuple — the defect is the direction of the check, and any list of refused roles leaves unrecognized values authorized. Do not report the env-var channel itself as the defect; it is a sanctioned pattern here and the finding is the missing disclosure. Do not treat the 7/7 and 132/132 passing runs as evidence against B1 or B5 — no test drives a role outside the refused tuple, every test stubs the role resolver, and neither the incident opt-out nor the incident-failure path is exercised.
