fix(launchd): revivers and install.sh respect an operator launchctl disable - #750
Conversation
throughput-watchdog.py checks `launchctl print-disabled gui/$UID` before counting a stalled tick; a `"<label>" => disabled` watch label yields action `disabled_by_operator` with no bootstrap and no kickstart. install.sh load_plist prints SKIP and returns 0 for a disabled label instead of `launchctl enable` + bootstrap. The shared is_launchd_label_disabled primitive (health-check's reviver guard) now also accepts the current `=> disabled|enabled` vocabulary, which it missed on macOS 14+ and so never blocked health-check's bootstrap.

On older supported macOS releases where launchctl print-disabled reports "<label>" => true, this helper treats the label as enabled and proceeds to launchctl enable/bootstrap; _watch_disabled_by_operator has the same omission and can resurrect the watcher. The updated shared parser at src/brainlayer/launchd_primitive.py:150-156 explicitly recognizes both true|false and disabled|enabled, so these two new guards need equivalent handling.

Fixed in d5b3e5f: both guards now accept the legacy boolean form (label mapped to true) alongside the current disabled form — install.sh label_disabled_by_operator and throughput-watchdog.py _watch_disabled_by_operator — matching launchd_primitive.py. Tests parametrized over both forms (tests/test_launchd_hygiene.py, tests/test_throughput_watchdog.py).

When install.sh hotlane-brainbar or install.sh all encounters a disabled hotlane label, this successful early return does not tell install_plist that loading was skipped. The caller consequently runs verify_hotlane_runtime at lines 551-552; if the intentionally disabled job is stopped, verification waits and fails, issues a bootout, and makes the installation return nonzero instead of honoring the skip. Propagate the skipped state so hotlane runtime verification is bypassed.

Agreed it is a check-then-act window, and rowed rather than fixed here: the window is the ~1 s inside one install.sh invocation between the guard and its own enable/bootstrap, and the revivals we are closing (reboot resurrection, the 60 s watchdog cycle, the M1 fleet watchdog) all happen across invocations, which this PR now guards. The follow-up that adds the two still-unguarded revivers (tier0-watchdog.sh:216,218 and health_check.py:732 _kickstart) will re-check label_disabled_by_operator immediately before every enable/bootstrap/kickstart so the check and the act are adjacent everywhere. Tracked in the sprint plan R1 rows.

If launchctl print-disabled fails—for example, because of a transient launchd or GUI-session error—|| true converts the failure into an empty listing, so this helper reports that the label is enabled and load_plist later executes launchctl enable, clearing the operator disable this change is intended to preserve. Return a distinct error and abort loading unless the disabled-state query succeeded; otherwise an installer run can silently resurrect an intentionally stopped, high-CPU service.

When launchctl print-disabled fails while input is pending, this action suppresses recovery but is not included in main()'s failure-action set, so the throughput-watchdog LaunchAgent exits 0 every minute even if the query remains broken and ingestion stays wedged indefinitely. Preserve the fail-closed behavior, but return nonzero—and preferably alert—for disabled_state_unknown so this degraded state is operationally visible.

Correct on the ordering — the alert serializes the default 0 for no_progress_seconds because alert_fn runs before that field is computed. Rowed for the watchdog follow-up PR (the one that guards tier0-watchdog.sh and health_check.py _kickstart) rather than a fourth round here: the fail-closed behaviour and the nonzero exit this round added are unaffected; only the alert payload under-reports the stall length. Follow-up moves the alert after the calculation and asserts the value in the existing unreadable-state test.

When the first disabled_state_unknown alert raises—for example, because the alert log path is temporarily unwritable—the exception is recorded, but the state written later still sets last_action to disabled_state_unknown. Every subsequent watchdog tick therefore fails this condition and never retries the notification until another action intervenes, turning “once per episode” into zero successful pages. Track successful delivery separately, as the existing recovery episode latch does, and retry after failures.

Both alert-path points are right and are rowed together with the alert-ordering item for the watchdog follow-up PR (rounds on this PR are closed by lead ruling; these are P2s on the notification, not on the fail-closed behaviour or the nonzero exit, which are what this PR ships). Follow-up: (1) gate the once-per-episode page on a recorded successful delivery, not on last_action, so a failed alert retries next tick; (2) give disabled_state_unknown its own alert body naming the unreadable launchd state and the operator action, instead of the generic "automatic recovery is starting" fallback; (3) compute no_progress_seconds before the alert.

When launchctl print-disabled fails, this new call passes a disabled_state_unknown result to _best_effort_alert, but that function's fallback body at lines 531-535 says that “automatic recovery is starting.” This branch intentionally performs no recovery and exits nonzero, so its desktop and HTTP notifications falsely reassure the operator instead of identifying the unreadable launchd state that requires intervention. Add a dedicated alert body for this action.

When BRAINLAYER_LAUNCHD_UNLOAD_ATTEMPTS (or the hotlane-specific override) is invalid, this new guard calls launchctl print-disabled before validating it; if the label is disabled, it even returns success without reporting the invalid configuration. This breaks the rejected-invocation contract and the Python 3.12 test requiring invalid overrides to exit before any launchctl call. Move the disabled-state check after override selection and validation, but before bootout or other launchctl mutations.

Fixed in e0175ad: the override validation now runs before label_disabled_by_operator, so a rejected invocation exits before any launchctl call and the 3.12 test (test_launchd_installer_rejects_invalid_unload_attempt_overrides) is green locally; the disabled-label early return can no longer mask an invalid configuration.

When the pending/no-progress path is exercised without an injected command_runner, this new call invokes the real launchctl; on the Ubuntu runners used by .github/workflows/ci.yml, that executable is absent, _watch_disabled_state returns unknown, and test_chunk_progress_or_no_pending_input_resets_stall_counter gets stalled_ticks == 0 instead of 1. I reproduced this with pytest -q tests/test_throughput_watchdog.py (1 failed, 39 passed), so every Python CI matrix job will fail until the test supplies an enabled-state runner or the platform boundary is otherwise isolated.

Fixed in 3b18a88 (test hygiene only): every run_once call in tests/test_throughput_watchdog.py now injects a shared _enabled_command_runner (answers print-disabled with an enabled listing), so no test shells the real launchctl. _watch_disabled_state is unchanged — a missing launchctl still fails closed. Parity proof with launchctl hidden from PATH: 1 failed → 40 passed.

Inject a shared _enabled_command_runner into every run_once call that lacked one; on Linux CI launchctl is absent, so the fail-closed _watch_disabled_state read 'unknown' and stalled_ticks stayed 0. Proven with launchctl hidden from PATH: 1 failed -> 40 passed. Repair round 2 on #750 (Codex 3916969244). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Size: S (+165/−7 across 5 files, 2 commits; one idea: revivers respect an operator
launchctl disable).Today
com.brainlayer.watchwas deliberately disabled (it resurrected on reboot at 97% CPU — the typing-lag process) and two revivers fought that: the in-repothroughput-watchdogtreated the disabled label as a stall and hitlaunchctl bootstrapevery 60 s (Bootstrap failed: 5: Input/output error— what bootstrapping a disabled label returns — logged asrecovery_failed), andinstall.sh load_plistlaunchctl enabled every label it touched. BrainLayer memory from 2026-08-01 says hotlane, enrichment and drain were also disabled then as writers — and hotlane was running today. Same class: an enable-everything path undoing an operator decision.scripts/launchd/throughput-watchdog.py: before any bootstrap/kickstart of the watch label, checklaunchctl print-disabled gui/$UID; if=> disabled, emit"action": "disabled_by_operator"and do not count the tick as stalled.scripts/launchd/install.shload_plist: anycom.brainlayer.*label shown=> disabledis skipped withSKIP: … disabled by operator (launchctl enable gui/$UID/<label> to re-arm)— never enabled.

Changes launchd load/recovery behavior on macOS: mis-parsed or failing
print-disabledcan block installs or fail watchdog runs instead of auto-reviving services, which is intentional but affects production fleet stability.Overview
launchd revivers no longer fight an operator
launchctl disable. Bothinstall.shload_plistandthroughput-watchdog.pyquerylaunchctl print-disabled gui/$UIDbefore enable, bootstrap, or kickstart. Labels listed as=> disabled(or legacy=> true) are left alone: the installer prints a SKIP with a re-arm hint and setsLOAD_PLIST_SKIPPEDso hotlane runtime verification does not run on a skipped label; unreadable disabled state fails the installer closed with an error instead of loading.The throughput watchdog treats pending work behind a disabled or unreadable label as not a stall (
disabled_by_operator/disabled_state_unknown), resets stall counters, and skips recovery. Unreadable disabled state triggers a one-time alert per episode and causes the watchdog process to exit non-zero.is_launchd_label_disabledinlaunchd_primitive.pynow parses current macOSdisabled/enabledwording as well as oldertrue/false, so callers likeinstall_and_verify_launchagent(health-check) recognize operator disables consistently. Tests cover skip paths, fail-closed behavior, and updated launchctl command ordering.Reviewed by Cursor Bugbot for commit 3b18a88. Bugbot is set up for automated code reviews on this repo.
