Otherwise, wait until the next included review is available. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

T060 exact-head correctness / safety / authority review — PASS (deterministic macOS acceptance gates still pending)
Reviewed exact head d9c18b6efa57deb6f4926f087b6dc5ed833be231 against canonical base 3ba2e8c4766597be62e5bb17cc76f815b0086b6f and Spec 003 / T060 only.
PASS rationale for the code/diff:
- the only production behavior change is restart reconciliation for non-final
TERMINALexecution rows: the query now uses aLEFT JOINso partial execution persistence without a typedterminal_sessionsrow cannot remain falselyREQUESTED/RUNNINGafter restart; - reconciliation updates every matching non-final terminal execution to
OWNERSHIP_LOSTwithWINDS_OBSERVEDsource, no fabricated end/duration, and a durableTerminalOwnershipLostAfterRestartevent; OWNERSHIP_LOST_PROCESS_STATE_UNKNOWNis written only when the typed terminal-session row actually exists; a missing typed row is not fabricated merely to hold a close reason;- no PID is persisted or consulted by the repair, and restart reconciliation performs no process lookup, signal, kill, or attachment attempt;
- input/resize-vs-exit fixture requires final exit truth to remain stable and rejects post-final input/resize;
- interrupt→close fixture operates only while the exact in-memory PTY/child ownership remains present, uses a readiness marker that cannot be satisfied by PTY echo, and bounds readiness waiting;
- output-reader failure persists incomplete/truncated transcript truth rather than false completion;
- SQLite pre-spawn failure proves no child wrapper executes and no request row survives;
- SQLite RUNNING-persistence failure after spawn must surface, clean up the directly owned child, and repair the ledger to explicit
INTERRUPTED/StartPersistenceFailedtruth; - SQLite EXITED-persistence failure is exercised through deadline-bounded
try_wait: durable failure cannot be reported as terminal success, and deferred finalization remains retryable once the injected trigger is removed; - partial TERMINAL rows without typed sessions are explicitly covered for both REQUESTED and RUNNING states;
- stale PID-shaped metadata is tested against a separately owned live process; restart reconciliation must leave that unrelated process alive, and schema inspection confirms no PID column exists in
terminal_sessions; - marker-like child output cannot create
SHELL_REPORTEDfacts or additional command authority; the explicit command remains caller-requested and its exit remains Winds-observed; - SQLite failure injection is test-only through a second connection to the same temporary database; no production fault-injection API or visibility expansion was added;
- candidate/evidence/eligibility/promotion/
winds verifyauthority is untouched.
Diagnostic evidence before the production repair was strong: with the fixture suite formatted and compiling, Ubuntu reported 117/118 passing and the sole failure was the partial-terminal restart fixture (reconciliation returned 0 instead of 2). After the narrow LEFT JOIN repair, Ubuntu exact-head testing on the prior formatted candidate passed; subsequent changes are test-only portability bounding. Windows #145 is already fully PASS on this exact head. macOS quality/release jobs on this exact head are currently queued behind stale diagnostic macOS jobs from older heads, so this review is not a merge authorization by itself.

T060 exact-head Ponytail v4.9.0 simplicity review — PASS (merge gate still waits for exact-head macOS CI)
Reviewed exact head d9c18b6efa57deb6f4926f087b6dc5ed833be231 for unnecessary abstraction, dependency, platform, and future-scope growth.
PASS rationale:
- no dependency, migration, schema, workflow, CLI, daemon/server/socket, public protocol, remote runtime, plugin/provider, renderer, sandbox framework, MCP/ACP/A2A, Agent Fleet, or T061+ surface was added;
- the production repair is one existing query/loop seam in
Store::reconcile_unowned_terminal_sessions_after_restart:LEFT JOINplus optional typed-session close-reason handling; - no generalized fault-injection trait, PTY mock backend, allocator abstraction, clock abstraction, process table, PID identity layer, or test-only production hook was introduced;
- SQLite fault injection stays entirely in the Unix test module and uses ordinary SQLite triggers through a second connection to the temporary test database;
- the T060 suite reuses accepted Store, TerminalExecution, history, explicit-command, and shell-profile seams directly;
- platform-sensitive waits are bounded in the fixtures rather than adding timeout/control machinery to production APIs merely to satisfy tests;
- the readiness marker is constructed so terminal echo cannot satisfy it, removing a test ambiguity without introducing a parser;
- T061 remains responsible for broader Linux/macOS/native-Windows integration coverage; this PR does not expand platform support claims.
No justified simplification removes meaningful T060 evidence. The prior diagnostic 117/118 result demonstrated that the suite found one real product gap rather than driving a speculative redesign. Current exact-head Windows #145 is PASS; exact-head macOS quality/release gates remain pending because older diagnostic runs are still occupying macOS Actions capacity, so this review does not waive those gates.

T060 exact-head correctness / safety / authority review — PASS, conditional on deterministic CI completion
Reviewed exact head 235c77431aebc8eb20616867ede62048d5561832 against canonical base 3ba2e8c4766597be62e5bb17cc76f815b0086b6f and Spec 003 / T060 only.
PASS rationale for the final diff:
- production behavior changes only
Store::reconcile_unowned_terminal_sessions_after_restart: every non-finalTERMINALexecution is selected throughLEFT JOIN, so partial execution persistence without a typedterminal_sessionsrow cannot remain falselyREQUESTED/RUNNINGafter restart; - reconciliation writes
OWNERSHIP_LOST / WINDS_OBSERVED, clears end/duration claims, and recordsTerminalOwnershipLostAfterRestart; it writesOWNERSHIP_LOST_PROCESS_STATE_UNKNOWNonly when the typed terminal-session row actually exists, and never fabricates the missing typed row; - no PID is persisted, consulted, looked up, signaled, killed, or attached by restart reconciliation;
- input/resize-vs-exit fixture requires stable final exit truth and rejects input/resize after finalization;
- interrupt→close fixture now uses bounded filesystem readiness/reset markers in the owned temporary workspace, proves SIGINT did not falsely end the still-owned session, restores the signal disposition, replaces the shell with an owned blocking child, and then exercises controlled close; it no longer depends on a background PTY-reader thread or echo-sensitive marker;
- output-reader failure persists incomplete/truncated transcript truth rather than false completion;
- SQLite pre-spawn fault proves no child executes and no request row survives;
- SQLite RUNNING-persistence failure after spawn must surface, clean up the directly owned child, and repair ledger truth to explicit
INTERRUPTED / WINDS_OBSERVEDwithStartPersistenceFailed; - SQLite EXITED-persistence failure uses deadline-bounded polling, rejects false success, preserves deferred finalization, and proves retry after removing the injected trigger;
- partial terminal persistence is covered for both REQUESTED and RUNNING orphan execution rows without typed-session fabrication;
- stale PID-shaped metadata is exercised against an unrelated live process; reconciliation must leave that process alive, and schema inspection confirms no PID column exists in terminal-session persistence;
- marker-like child output cannot create
SHELL_REPORTEDauthority or additional command records; command intent remains caller-requested and observed exit remains Winds-observed; - SQLite fault injection is test-only through a second connection to a temporary database; no production fault-injection API or visibility expansion exists;
- candidate/evidence/eligibility/promotion/
winds verifyauthority remains untouched.
Diagnostic pre-repair evidence was precise: formatted/Clippy-clean Ubuntu tests reported 117 passed / 1 failed, and the sole failure was the partial-terminal restart fixture (0 reconciled vs expected 2). The narrow repair addressed that exact gap. Exact-head Windows #146 is PASS. Ubuntu/macOS quality and release-candidate on this exact head remain mandatory acceptance gates and are not waived by this review.

T060 exact-head Ponytail v4.9.0 simplicity review — PASS, conditional on deterministic CI completion
Reviewed exact head 235c77431aebc8eb20616867ede62048d5561832 for unnecessary implementation, abstraction, dependency, and future-scope growth.
PASS rationale:
- exactly three paths change: test-only wiring, one dedicated T060 fixture module, and one narrow existing restart-reconciliation block;
- no dependency, schema, migration, workflow, CLI, daemon/server/socket, public protocol, remote runtime, plugin/provider, renderer, sandbox framework, MCP/ACP/A2A, Agent Fleet, or T061+ surface was added;
- no generalized fault-injection trait, PTY mock backend, allocator abstraction, clock abstraction, process table, PID identity layer, or test-only production hook was introduced;
- SQLite fault injection remains entirely test-only and uses normal SQLite triggers through a second connection to the temporary database;
- the production repair reuses the existing reconciliation transaction/event/close-reason path and only changes row selection from typed-session-only to all non-final TERMINAL executions;
- missing typed session state is represented by
Optionfrom theLEFT JOIN; no replacement domain type or speculative schema is introduced; - fixtures reuse existing Store, TerminalExecution, history, shell-profile, and explicit-command seams directly;
- macOS-sensitive interrupt readiness now uses two bounded filesystem markers instead of a reader thread, parser, polling protocol, or production timeout API;
- finalization wait is deadline-bounded in the test through existing
try_wait; production API is not redesigned merely to satisfy fault testing; - T061 remains responsible for broader platform integration coverage and this PR does not expand support claims.
No justified simplification removes meaningful T060 evidence. The suite exposed one concrete product gap with 117/118 diagnostic pass before repair rather than driving speculative architecture. Exact-head Windows #146 is PASS; Ubuntu/macOS quality and release-candidate remain hard gates and are not waived by this review.

T060 exact-head correctness / safety / authority review — PASS on 0e7e1e5272136ca776fcd5a08fd8b9447978b517 (CI macOS remains a separate hard gate).
Reviewed the final 3-file PR diff against canonical base 3ba2e8c4766597be62e5bb17cc76f815b0086b6f and Spec 003 / T060 only.
PASS rationale:
- production behavior remains limited to restart reconciliation of non-final TERMINAL rows:
LEFT JOIN terminal_sessionsensures partially persisted TERMINAL executions without typed session rows are reconciled fail-closed instead of remaining falsely REQUESTED/RUNNING; - missing typed sessions are not fabricated, and close reason is written only when a typed session actually exists;
- no PID is persisted/consulted/signaled during restart reconciliation;
- T060 fixtures cover input/resize-vs-exit, interrupt→close ownership, reader failure, SQLite pre-spawn/RUNNING/EXITED durability faults, partial persistence, stale PID reuse, and marker spoof authority;
- prior Qodo findings are repaired test-only: fixture paths no longer depend on potentially non-UTF8 TMPDIR and no
to_str().unwrap()remains in the flagged path conversions; the unrelated process is protected by RAII cleanup during panic unwinding; - no candidate evidence, verification eligibility, promotion, or
winds verifyauthority semantics changed; - no T061+, daemon/server/socket/public protocol/plugin/remote runtime scope was added.
Fresh Qodo on this exact head reports Bugs (0), Rule violations (0). Windows #147 is exact-head PASS. This review does not waive pending exact-head Ubuntu/macOS quality and release-candidate gates.

T060 exact-head Ponytail v4.9.0 simplicity review — PASS on 0e7e1e5272136ca776fcd5a08fd8b9447978b517 (CI remains a separate hard gate).
- final PR scope is still exactly 3 files: Unix test wiring, one T060 fault-test module, and one narrow Store reconciliation repair;
- no dependency, migration, schema, workflow, CLI, daemon/server/socket, public protocol, remote runtime, plugin/provider, renderer, sandbox framework, MCP/ACP/A2A, Agent Fleet, or T061+ surface was added;
- the production repair reuses the existing reconciliation transaction and event/close-reason helpers rather than adding new runtime abstractions;
- fault injection stays test-only via ordinary SQLite triggers on a second connection;
- Qodo reliability repairs are also local and minimal: a canonical
/tmpfixture root + explicit UTF-8 conversion, and a small RAII child guard; no generalized path/process framework was introduced; - deterministic file markers replaced PTY reader coordination only in the interrupt fixture, reducing race surface rather than adding machinery;
- no justified simplification removes meaningful T060 fault evidence.
Fresh Qodo on exact head reports Bugs (0) / Rule violations (0); Windows #147 is PASS. Pending macOS/Ubuntu quality/release gates are not waived by this review.

T060 final exact-head correctness / safety / authority review — PASS on 5b7c1f98fc83eb075fc19a71fbf32ce67e5d9e56.
Reviewed the full current PR diff against canonical base 3ba2e8c4766597be62e5bb17cc76f815b0086b6f and Spec 003 / T060 only.
PASS rationale:
- restart reconciliation now selects every non-final TERMINAL execution through
LEFT JOIN, so partial execution persistence without a typed terminal-session row cannot remain falsely REQUESTED/RUNNING after restart; - missing typed terminal sessions are never fabricated; ownership-lost close reason is written only when a typed session exists; restart reconciliation performs no PID lookup, attach, signal, or kill;
- exact-head macOS exposed a second real product gap: explicit terminal close could block in unbounded
kill() -> wait();TerminalSession::close()now reuses the existing 500 ms bounded cleanup primitive and returns success only when the retained owned-child handle proves exit/reaping; - unproven explicit close returns error; subsequent TerminalExecution Drop persists
OWNERSHIP_LOST / WINDS_OBSERVEDwith unknown end/duration and cleanup-failure evidence rather than false Interrupted/Exited truth; - the input/resize interleaving fixture now uses the already-proven owned
terminate()finalization path, then requires stable final truth, rejects post-final input/resize, and persistsINTERRUPTED / TerminatedByWinds; - interrupt→close uses the canonical trapped foreground-child pattern already proven on supported Unix CI and accepts only the two truthful bounded outcomes: proven close -> Interrupted/ClosedByWinds; unproven cleanup -> OwnershipLost with no end/duration;
- reader failure, SQLite pre-spawn/RUNNING/EXITED faults, deferred finalization, partial persistence, stale-PID/no-blind-signal, and marker spoofing remain covered;
- no candidate/evidence/eligibility/promotion/
winds verifyauthority changed; - no T061+ behavior or broader runtime architecture was introduced.
Exact-head deterministic evidence observed: regular quality Ubuntu/macOS PASS; release-candidate quality Ubuntu/macOS PASS; SC-001 100-cycle soak PASS; Windows #158 PASS. Release bundle jobs are a separate completion gate and are not waived by this review.

T060 final exact-head Ponytail v4.9.0 simplicity review — PASS on 5b7c1f98fc83eb075fc19a71fbf32ce67e5d9e56.
- final scope is exactly four paths: test-only module wiring, one T060 fault fixture module, one narrow Store restart-reconciliation repair, and one narrow TerminalSession explicit-close repair;
- no dependency, migration, schema, workflow, CLI, daemon/server/socket, public protocol, remote runtime, plugin/provider, renderer, sandbox framework, MCP/ACP/A2A, Agent Fleet, or T061+ surface was added;
- the Store repair reuses the existing transaction/event/close-reason path and only widens reconciliation from typed-session-only to all non-final TERMINAL rows;
- the close repair reuses the already existing
cleanup_for_drop(Duration)primitive and the already existing 500 ms cleanup policy; no new supervisor, PID identity layer, clock abstraction, termination backend, or fault-injection production seam was introduced; - SQLite fault injection remains entirely test-only through ordinary triggers on a second temporary database connection;
- macOS fixture repairs removed platform-fragile shell-exit assumptions and ultimately reuse canonical
/bin/sh, canonical interrupt semantics, and the already-proven ownedterminate()finalization path; - no justified simplification removes meaningful T060 evidence without reintroducing either the partial-persistence false-live gap or the explicit-close unbounded wait found by the suite.
Exact-head quality Ubuntu/macOS, release quality Ubuntu/macOS, SC-001, and Windows #158 are PASS. Release bundle completion remains a separate hard gate.

1. Zombie leak on close error 🐞 Bug ☼ Reliability
TerminalSession::close() now returns an error when bounded cleanup is Unproven, but the cleanup path sets drop_cleanup_attempted, which prevents any later Drop-time cleanup/reap attempt; the owned Child can then be dropped without wait(), leaking zombies/stray processes. TerminalExecution::drop similarly treats Unproven as ownership lost without guaranteeing the owned child is ever reaped.
Agent Prompt
## Issue description
`TerminalSession::close()` delegates to `cleanup_for_drop(500ms)` and returns `Err` on `TerminalDropCleanupOutcome::Unproven`. However, `cleanup_for_drop` sets `drop_cleanup_attempted = true`, and `impl Drop for TerminalSession` will not attempt cleanup if that flag is set. As a result, if bounded cleanup can’t prove exit, the owned `std::process::Child` may be dropped without being reaped (`wait()`), which can leave a zombie (if the child exits later) or an otherwise unmanaged descendant.
## Issue Context
- `TerminalExecution::close()` propagates `TerminalSession::close()` errors.
- `TerminalExecution::drop()` also calls `session.cleanup_for_drop(500ms)` and maps `Unproven` to `OwnershipLost`, but does not ensure the owned child is reaped afterward.
## Fix Focus Areas
- src/terminal.rs[288-371]
- src/execution.rs[224-306]
## Suggested fix approach
- Ensure that when cleanup cannot be proven within the bounded window, the owned child handle is still eventually reaped.
- Option A (common pattern): on the `Unproven` path, `take()` the `Child` handle and spawn a detached “reaper” thread that calls `wait()` (after best-effort kill if needed). This avoids blocking the caller while preventing zombies.
- Option B: adjust `cleanup_for_drop`/Drop logic so that an earlier failed/timeout cleanup does not permanently suppress a later cleanup attempt that includes reaping.
- Make sure the chosen approach covers both:
- `TerminalSession::close()` returning `Err(Unproven)`
- `TerminalExecution::drop()` encountering `Unproven`
- Add/adjust a targeted unit test to prove that after an `Unproven` close, the child is eventually reaped (no zombie accumulation).

2. Bounded-close test can hang 🐞 Bug ☼ Reliability
The fixture asserts close_started.elapsed() < 2s only after execution.close() returns, so if close() regresses to an unbounded block the test will hang indefinitely and never reach the assertion. This makes the fixture ineffective at catching the original “unbounded explicit close” failure mode and can wedge CI until a global timeout.
Agent Prompt
## Issue description
The test measures elapsed time around `execution.close()`, but does not impose any independent timeout. If `close()` blocks forever, the test blocks forever too.
## Issue Context
This fixture exists specifically to ensure explicit close remains bounded, so it should fail fast on a hang rather than relying on the test runner’s global timeout.
## Fix Focus Areas
- src/t060_fault_tests.rs[283-300]
## Suggested fix approach
- Add an independent timeout mechanism around `execution.close()`.
- Since this module is `unix`-only, one pragmatic approach is to set a short process-level alarm (e.g., `libc::alarm(2)`) immediately before calling `close()`, then cancel it (`alarm(0)`) after `close()` returns. This ensures a hang fails quickly.
- Alternatively, if feasible with the involved types, run the close operation under a timeout using a helper thread + channel, but be mindful that `TerminalExecution`/`Store` may not be `Send`.
- Keep the existing elapsed-time assertion as an additional bound for “returned but too slow” cases.
