Owner report 2026-10-17:
infraternal statusprints "State Unknown / service state could not be read" on monitor01 (system unit infraternal-server.service) and minipc01 (system unit infraternal-agent.service).Root cause (crates/infraternal/src/main.rs, systemd_server_state): (1) it matches only units whose description is "infraternal server ()", but the production unit is described "infraternal server"; (2) it treats a failing
systemctl --user(no user bus when root) as "a manager did not respond" and answers Unknown; (3) it never looks for an agent unit, so a host is "node"/"Not available yet" for everything.Fix: detect role from unit files + data dirs (system and user), real state per component, no network, <=50 ms. Branch cli-status-truth, base
895bcdd23. TASTE row "The CLI knows what it is running on".Started. Branch cli-status-truth, base
895bcdd23. Finding: production unit is described "infraternal server" (no name suffix) and root has no user bus, so old probe returned Unknown. Fix commit10d010acc, 8 fixture tests pass, status runs in 36 ms (debug build). Gate output follows when verify fast ends.Finished. Head
6937ef59bfon cli-status-truth (pushed).Size vs origin/dev: x86_64 +17280 B (limit 16384, over by 896... see report), aarch64 +14720 B. Cap not raised.
Release 4 deployed to production at 21:21 IST: release-prod-live
a906ede87, server sha256 c821a30a…, /healthz ok. CLI overhaul (#239, #237). CA locked after the restart until the owner unlocks it.Launch QA P1 reproduction: after an invalid system service configuration,
infraternal statussaid Running while systemd showedMainPID=0,Result=exit-code,SubState=auto-restart,NRestarts=45, and no listener;/healthzreset. I added thelaunch-qalabel and attached the sanitized evidence: crash-loop status result. The initial configuration was a QA fixture mistake, but the reported status was inaccurate; tracking here because it overlaps this issue's status-truth scope.kayg referenced this issue2026-10-28 17:53:56 +00:00
Started implementation on status-crash-loop-237, base
0c8639496(origin/dev). Read #237 and all comments, #247 launch-QA history, D299/D303 and the CLI TASTE row. Reproducing the auto-restart false positive before changing the local unit-state probe; both service roles and manager scopes remain in scope. Static images will be measured sequentially against dev 21,431,472 / 19,605,896 bytes.Finding: crates/infraternal-status/src/lib.rs requests only ActiveState and maps activating to Active. A real transient systemd user service (Restart=always, RestartSec=200ms, StartLimitIntervalSec=0, immediate exit 1) produced MainPID=0, Result=exit-code, NRestarts=3, ActiveState=activating, SubState=auto-restart, ExecMainCode=1, ExecMainStatus=1. Fixture stopped; no service left running.
Additive D299 change proposed for this fix: state
restarting, component textRestarting repeatedly, with last exit status/signal in state_detail and a scoped journalctl next step. D303 exit 5 applies. The probe will also recognize recent repeated starts and changes between consecutive observations, without network or a deliberate sampling wait. No dependency change.Reproduction and fix evidence: pre-fix real-user regression fails because the unchanged probe returns Active; real user unit properties show the immediate-exit Restart=always fixture in auto-restart. The same real-user regression passes with the new probe (1 passed). Fixture was stopped and is inactive.
Implementation adds local property parsing, a 10-second recent-restart window, immediate consecutive-observation checks for fresh PIDs, and per-query/whole-probe query budgets. Historical restart counts on an older stable process remain Running. Human/JSON regressions exercise system/user × server/infraternal-agent × auto-restart/recent-repeat/healthy/recovered/stopped/failed/unavailable-manager states. No network, dependencies, features or release-profile changes.
Step complete:
f357c0a7e, pushed on status-crash-loop-237. Repeated restarts now report Restarting repeatedly, last exit status/signal (explicitly unavailable when the manager has none), journalctl for the owning scope, JSON state restarting and exit 5. fmt and touched-crate clippy pass; status crate: 16 passed, 1 manual real-user regression ignored in the ordinary suite; the manually provisioned real-user regression passed separately. CLI envelope/review/status suites: 20 passed. The initial scratch path exceeded SUN_LEN in 3 pre-existing socket tests; all passed with a shorter alias to the same job-owned scratch directory. Sequential pinned x86_64/aarch64 static builds are running next.How to test: start a service with Restart=always and an immediate nonzero exit; run infraternal status and infraternal status --json; expect Restarting repeatedly, exit 5 and the scoped journalctl next step. Stop the fixture afterward.
Step complete:
60c5b6e3e, pushed. Real CLI verification exposed an over-tight 20 ms per-unit deadline: a cold responding manager was reported Unknown. Before with a delayed manager. The probe now shares one 40 ms manager budget across all units rather than splitting it; a functional delayed-response regression passes for both roles/scopes. Fmt, clippy, 16 status tests and 20 CLI tests pass again.After: real transient user-service output in human form and D299 JSON, both exit 5. Both job-owned transient units are inactive. The static build was interrupted before measurement to include this correction, then restarted sequentially. No shared-host timing is claimed as performance evidence.
Step complete: exact D243 caps and docs/PROCESS.md comparison committed/pushed as
4620c8fd2b. Pinned stripped static recipe on 8by64-compute02, targets built one at a time:0c8639496Both are below 16 KiB; no dependency/feature/profile changes. Caps have no allowance. Sequential build receipt; exact/over/shrink boundary checks pass on both targets. scripts/verify fast is running on this head through the shared build slot.
Gate finding on
4620c8fd2: the default real-engine fixture root is too long for the 7-digit build-host PID in replay_size_review. Failure occurs before the replay test runs, in scripts/agent_fixture.py:67:The helper already supports INFRATERNAL_AGENT_TEST_STATE_ROOT / INFRATERNAL_TEST_STATE_ROOT. The rerun will point both to the shorter job-owned scratch alias (as TMPDIR already does); no product or test-source change is needed. Remaining Rust checks from this first run are finishing before the same-head full gate is rerun, without overlapping build slots.
The corrected same-head full gate is waiting in the shared build-slot queue and has not begun producing output. Implementation and exact size-cap commits are already pushed at
4620c8fd2; first-run static checks and all Rust rows except the recorded fixture-root setup failure passed. Waiting for a normal slot with the shorter fixture-root settings; no owner action or priority override is needed.Correction to the rerun setup: using the short symlink as INFRATERNAL_TEST_STATE_ROOT made restart admission tests correctly reject the path with PermissionDenied. Replaced it with a real, job-owned 0700 directory at ~/.cache/codex-scratch/s237a (all three fixture-root variables now use it). Focused restart admission and adopted replay tests both pass with that directory. No source change.
The second run also failed session::user_host::tests::bulk_turn_advances_sixteen_kib_and_yields_before_the_rest at user_host.rs:1756 (
assertion failed: session.drained); the first same-head process-per-user row passed. Rechecking in the next full gate without changing that code. Both runs' static rows pass at the exact recorded caps. Full same-head gate started again through the normal build slot.The third run's only failing row was the workspace test row: daemon::gone_tests::a_vanished_session_gets_a_final_close_and_the_channel_stays_up could not bind its long socket name below TMPDIR (daemon_gone_tests.rs:119, SUN_LEN). All other Rust rows, including process-per-user and both static checks, passed. Reserved a real 0700 one-character job directory under ~/.cache/codex-scratch, short enough for that fixture; the exact failed test passes there. Rerunning the full same-head gate with TMPDIR and both state-root overrides on that real directory. No source change.
The full gate passed on
4620c8fd2with a real 0700 one-character scratch root (TMPDIR and both fixture-root overrides). Final self-review then found a mixed-role wording regression: one restarting service plus a stopped/failed companion was described as both restarting. Failing regression.Fixed/pushed as
d96c0a0e0: partial-setup headline for mixed restarting/stopped/failed roles, unchanged individual component facts, full grouped headline only when both restart. Both choices of restarting role are covered. Fmt, status-crate clippy and all 17 ordinary status tests pass. Remeasuring both pinned static images sequentially, then refreshing the exact caps/table and rerunning the full gate on the corrected head.Final corrected size caps/table pushed as
98195e23d4. Mixed-role repair adds 384 bytes per target; the pinned sequential images are now 21,438,608 / 19,611,752 bytes, +7,136 / +5,856 versus dev0c8639496(21,431,472 / 19,605,896). Both remain below 16 KiB. Exact caps have no allowance; no dependency/feature/profile change.Corrected sequential build receipt; final exact/over/shrink checks. Full scripts/verify fast is running on this corrected head with the proven real short fixture directory; final output and target cleanup follow.
Finished implementation on status-crash-loop-237, pushed head
98195e23d4(base dev0c8639496). Worktree is clean and origin matches this head. Issue remains open for review.Crash loops report Restarting repeatedly, last exit status/signal (explicit unavailable fallback), scoped journalctl guidance, D299 JSON state restarting and D303 exit 5. Covers auto-restart, recent repeated starts, changing PIDs, healthy/recovered/stopped/failed/unknown states, both roles and manager scopes, and mixed-role headlines. Real user-unit reproduction failed before the fix and passed afterward; ordinary status suite now has 17 passing tests, with the provisioned real-user check opt-in. The final full gate passes, including CLI envelope tests, workspace tests, both static providers and frontend checks.
Final pinned stripped static sizes on 8by64-compute02, built one target at a time:
0c8639496Both deltas are below 16 KiB. scripts/verify.d/rust.sh and docs/PROCESS.md use the exact measured caps without allowance. No dependency, feature or release-profile changes. Build receipt; boundary checks.

Independent verification review started on local review-status-crash-loop-237 at
98195e23d4; merge base with origin/dev is0c8639496b. Reviewing runtime restart observations, D299/D303, real job-owned user services, and sequential D243 images. No implementation changes or pushes are authorized. Evidence and gate transcripts remain outside the checkout.R237-01 | P1 | crates/infraternal-status/src/lib.rs:257,680-720 | A nonresponding system manager consumes the shared 40ms deadline before the user manager is queried. A user service known to be in auto-restart is classified Unknown, confirmed_down is empty, and the CLI exits 0 instead of D303's 5. Violates module contract that one unavailable manager does not hide the other manager's units. Test: unavailable_system_manager_preserves_user_restart_observation (crates/infraternal-status/tests/review_237.rs). Evidence: R237-01.log, observed left Unknown / right Restarting { code: 1, status: 1 }; test exit 101. System fixture uses exec /bin/sleep 1; user fixture answers immediately with actual auto-restart property shape. Child process is reaped; no lingering fixture processes.
R237-03 | P1 | crates/infraternal-status/src/lib.rs:712-720 | Every manager invocation now requires --timestamp=unix, introduced in systemd 251. Ubuntu 22.04 systemd 249 (249.11-0ubuntu3.23) rejects it with Invalid value: unix. before contacting the manager. All installed service states therefore become Unknown and D303 returns success even for failed/crash-looping services. Existing ActiveState queries worked on these clients. Test: older_manager_clients_preserve_failed_service_observation (crates/infraternal-status/tests/review_237.rs). Evidence: systemd249.log from an isolated ubuntu:22.04 container with the actual systemd package; R237-03.log observes Unknown instead of Failed, exit 101. The test fixture reproduces only that measured option refusal; no minimum supported systemd version was previously imposed by this status probe.
Review progress: four failing tests committed locally on review-status-crash-loop-237 at 9b6a5a1fc (no implementation edits or pushes). R237-01 P1 shared deadline hides a user-manager crash loop; R237-03 P1 actual Ubuntu 22.04 systemd 249 refuses the new unix timestamp format; R237-02 P2 backward wall-clock step makes repeated starts Running; R237-04 P2 masked server plus retained data produces a running headline for a stopped component (pre-existing, baseline checked separately). Findings file is maintained outside the checkout.
Real current-systemd functional checks pass for automatic restart, StartLimitBurst exhaustion, healthy, stopped and missing units. All job-owned transient units stopped. No hot-path change found, so no perf-VM run is required.
The original-head full gate remains queued through the shared build-slot wrapper; no output yet. It runs in a separate detached checkout of
98195e23dso the failing review tests do not alter its result. Sequential baseline static measurements follow the head gate; no overlapping heavy commands or perf measurements on this build host.Independent review evidence (review branch 9b6a5a1fc; no push):

Fix round 1 started on status-crash-loop-237, base
98195e23d4. Read all #237 comments, including the merge-after-fixes verdict and all four findings. Importing review test commits through9e5479bc1unchanged before implementation. Each unit/manager will retain independent evidence and deadline; older systemd support, monotonic restart windows and honest stopped headlines follow in separate commits. No deployment or dev merge.Imported the four review commits unchanged by fast-forward to
9e5479bc1and pushed. Pre-fix review_237 run: 0 passed, 4 failed (all four named findings reproduced). R237-01 now passes with concurrent unit probes and an independent 40 ms deadline per unit, including a second observation within that unit's budget. Touched-crate checks are waiting in the normal build-slot queue.Compatibility check: contracts/ssh-bootstrap.md supports usable Linux systemd without a version floor; docs and the installation contracts do not impose systemd 251. The review measured the actual systemd 249 option refusal. Use raw ExecMainStartTimestampMonotonic plus CLOCK_MONOTONIC rather than any timestamp-format option. If restart age cannot be established, preserve Unknown instead of claiming Running. Following D303's off-or-unreachable semantics and the fix brief, an installed service with an unavailable manager will exit 5; existing JSON fields remain intact. No new library or release-profile change.
Clarification after checking the older CLI review regressions: existing D303 tests explicitly distinguish an unanswered manager (Unknown, exit 0) from confirmed stopped/failed/restarting service (exit 5). Retaining that established behavior; the previous comment's proposed Unknown exit 5 is withdrawn. The fixes preserve readable down-state evidence so those services reliably exit 5, without declaring a service down solely because its manager query failed. The frozen review tests remain unchanged.
R237-01 fixed and pushed as
336a3af5f7. Unit observations run concurrently with independent 40 ms deadlines, so neither a stalled manager nor another unit can consume their budget. Worker failure retains the installed unit as Unknown. Rejected a serial/shared manager deadline. Workspace fmt, strict all-target status-crate clippy, 17 unit tests (1 opt-in real-service test ignored), and unchanged unavailable_system_manager_preserves_user_restart_observation all pass. Final whole-command gate and target sizes follow after all fixes.R237-03 fixed and pushed as
c5e6d9bce. Removed --timestamp=unix, which systemd 249 refuses, and requested the raw monotonic start property instead. Rejected increasing the minimum supported manager version. Failed manager calls still yield Unknown. Workspace fmt, strict all-target clippy for status/CLI, 17 unit tests, the unchanged older-manager regression and the CLI role/scope/human/JSON matrix all pass. The real host manager also accepts the raw monotonic-property query for an absent fixture unit.R237-02 fixed and pushed as
674f92c90. Restart age now compares ExecMainStartTimestampMonotonic to CLOCK_MONOTONIC in microseconds. Missing/incomparable timestamps with repeated starts report Unknown, never Running. Rejected wall-time subtraction and boot-time clocks because their adjustment/suspend behavior differs. Explicitly enabled nix's time API for this crate; that feature already exists in the shipping dependency graph (no new library/version).Fmt, strict touched-crate all-target clippy, 18 status unit tests, the unchanged clock-rollback regression and the CLI role/scope/text/JSON matrix pass. Boundary checks cover exactly 10 seconds, 10 seconds plus 1 microsecond, future monotonic values and missing age; a future wall timestamp has no influence. D243 measures the final native cost after the headline fix.
Additional functional evidence: the unchanged opt-in real-user crash-loop test passed (1 passed, 0 failed). The job-owned transient status-crash-loop-237.service used Restart=always / RestartSec=200ms and an immediate exit 1. The actual manager reported MainPID=0, NRestarts=3, ExecMainStartTimestampMonotonic=329848725652, ExecMainCode=1, ExecMainStatus=1, ActiveState=activating, SubState=auto-restart. Cleanup stopped/reset only this unit; manager now reports LoadState=not-found, ActiveState=inactive.
Added same-manager unit-isolation coverage: a stalled unit cannot hide another unit's restart evidence, in either system or user scope. Its ordering handshake makes the reviewed shared-deadline implementation fail regardless of directory enumeration order: pre-fix exit 101 (Unknown versus Restarting { code: 1, status: 7 }); corrected implementation passes. Temporary pre-fix checkout removed. Four imported review tests remain byte-for-byte unchanged. Full touched-crate/CLI review checks are waiting in the shared build-slot queue; no priority override or owner action is needed.
All four review findings are fixed. R237-04 pushed as
9b5c7ff89: a retained-data server without a readable unit now has a stopped headline, a service-restoration next step and D303 exit 5. Stopped/failed/unknown retain distinct wording; unknown units get scoped diagnostics. Rejected treating an empty discovered-unit list as healthy. Additional same-manager regression pushed separately asf61d3a6869(full SHA follows below).Focused checks pass: strict all-target status/CLI clippy; 20 status unit tests (1 opt-in test separately passed on a real transient unit); all 4 imported review regressions unchanged; same-manager regression; CLI envelope 8, first review 17, second review 11 and complete status matrix 1. Total CLI test functions: 37 passed. No JSON fields removed or renamed. Both scopes and both roles remain covered.

D243 static comparison remains queued in the normal shared build-slot wrapper; no build output or measurements yet. Source fixes and all focused checks are already pushed at
f61d3a686. Both slots were occupied when checked. Continuing to wait without a priority override; exact caps and the final fast gate depend on these measurements. No owner action is needed.The build slot became available as the queue note was posted. The static comparison is now running, beginning with origin/dev x86_64. All four images remain sequential in the same slot.
D243 baseline complete on origin/dev

Both match the dev caps exactly; file identifies static stripped images and PT_INTERP is absent. Branch x86_64 is building next, followed by aarch64, in the same slot.Self-review also removed an unnecessary job-launcher dependency from the new same-manager test: it now falls back to job scratch when CARGO_TARGET_DIR is absent. That exact no-environment invocation passes. This is test-only and does not change either shipping image; it will be committed after its strict clippy check.
D243 sequential pinned static comparison complete on 6by32-compute02, using scripts/static-cargo, one image at a time in one build slot. Both head images are stripped/static with no PT_INTERP.
2fb412d01f61d3a686Written ARM growth justification (task's >16 KiB rule): aarch64 grows 25,296 bytes, 8,912 bytes above 16 KiB, and remains below 64 KiB. This whole-branch cost retains independent bounded unit-query workers, their ownership/cleanup, monotonic restart-age handling and honest stopped/unknown diagnostics. The ordinary four role/scope combinations must retain independent evidence when any manager or unit stalls. The rejected shared serial deadline demonstrably hid restart loops; giving serial units full deadlines instead can add 40 ms per stalled unit. The selected workers exist only during the local CLI probe; no daemon data path, idle polling or network work is added. No new library, dependency version or release-profile change; the existing nix clock API is reused. These are total image deltas, not an unmeasured per-helper attribution.
The x86_64 increase is 480 bytes below 16 KiB. Exact caps and docs/PROCESS.md will use 21,447,376 / 19,631,192, with no allowance. Strict test-fallback clippy and exact/over/shrink cap checks are next, followed by the final-head fast gate.

No fixes, pushes or deploys. Latency evidence requires a perf VM under the shared rules; this build VM cannot supply accepted latency numbers.

The new down-count fallback requires overall Inactive; here overall is Active, so status follows its success path despite the known stopped server (D303). The unchanged single-role review regression passes because it has no healthy companion. New regression masked_server_beside_a_running_host_has_a_partial_setup_headline fails with the exact false headline.

336a3af5f| crates/infraternal-status/src/lib.rs:265-269.The independent worker repair creates one OS thread for every discovered unit, with no fallible spawn or resource bound. A child-only 192 MiB address-space limit and 96 fixture units cause the entire status probe to panic at std:🧵:scoped.rs:206: “failed to spawn thread: Os { code: 11, kind: WouldBlock, message: Resource temporarily unavailable }”. The join fallback cannot catch a spawn failure. The identical resource-refusal regression passes against
98195e23d. Fixtures only sleep; no host limits were changed and no CPU load was generated. This is a functional refusal check, not performance evidence.Target failure, round-1 pass. Test thread_resource_refusal_preserves_a_status_answer will be committed separately on local review-status-crash-loop-237-r2 after the untouched-target gate finishes.
Round-2 functional checks: 42 additional manager variants pass, including both roles/scopes, zero/missing/future monotonic starts, garbage and timeout on the second observation, healthy/recovered services, and two independent loops. Each observed unit made at most two calls; there is no whole-probe worker bound (R237-R2-02).
Two real job-owned transient user services at RestartSec=100ms / 300ms both reported Restarting with their own exit statuses 7 / 11. Both are now LoadState=not-found, ActiveState=inactive. Actual Ubuntu systemd client 249.11-0ubuntu3.23 accepts the exact new option/property query and reaches the expected “not booted with systemd” bus error in the container; no unsupported-option error. Daemon-backed functional coverage uses the build host’s 257 manager.
Latency remains a relay dependency under D250; scripts/perf-vm is absent and the rules prohibit this job contacting other hosts. A ready benchmark script is attached as text (rename to status-bench.py). On an approved perf VM with healthy installed services, copy the two review artifacts and run:
It refuses the build host, alternates 100 measured invocations per image after warmups, checks Running/exit 0, records host/load and p50/p95/max, and enforces head max <100 ms. Artifacts will be under /home/agent/.cache/codex-scratch/review-status-crash-loop-237-r2/artifacts/ after the sequential static builds. No build-host performance number is claimed.

All four images are stripped/static with no PT_INTERP.
2fb412d01cb2e6d1bdRelative to the previous round, this patch reduces x86_64 by 2,720 bytes and aarch64 by 1,312 bytes while closing both findings. Exact caps and docs/PROCESS.md now use these measurements with no allowance. Exact/one-byte-over/shrink/unsupported-target boundary checks all pass.
Written ARM growth reason: +23,984 bytes over dev is 7,600 bytes above 16 KiB and below 64 KiB. This is the measured whole-branch cost of monotonic restart/last-exit diagnostics, configured-role headline/exit accounting, and fallible bounded queries that retain independent evidence across manager scopes. It closes the committed P1/P2 cases; the previous any-running-unit shortcut and shared serial deadline demonstrably lost down-state evidence, while unbounded workers lost the whole answer on resource refusal. The final workers reserve at most 4 × 128 KiB = 512 KiB of configured thread stack per invocation (a configuration bound, not an RSS measurement), and at most four manager children; they leave no persistent daemon work. Healthy-service build-host timing follows the final gate. No new dependency, version, feature or release-profile change in this final fix round. Correction to the earlier round's dependency claim: nix/time is newly enabled in the normal shipping graph relative to dev, where it existed only in development dependencies; this receipt makes no per-helper size attribution.

systemctl maskwithout--nowdoes not stop an already running service. A real disposable user-manager server remained ActiveState=active/SubState=running/MainPID=1725470 before AND after status; the reviewed shipping image nevertheless printed “The server is not running”, JSON state=stopped/ok=false, and exit 5. D303 requires 0 for this running service. Masking a live service to prevent future activation is a realistic administrative operation, not a synthetic manager failure.The inactive-mask cases from previous rounds still need exit 5. Mask is activation configuration, not proof of runtime inactivity: the contract table must distinguish masked+running from masked+inactive just as it already does disabled+running. This affects both canonical roles/scopes. No production fix made. A failing regression will be committed after the untouched-target gate finishes. Under the owner's final-round rule this NEW P1 requires stopping the lane for redesign.
Real fixture was stopped/unmasked; LoadState=not-found, ActiveState=inactive, MainPID=0. Discovery used a private XDG_CONFIG_HOME copy of the mask; actual service and

Final-round functional checks complete (target
f9859712c): all 126 manager-shaped matrix cells and unconfigured-role case pass; four unchanged round-1 tests and both unchanged round-2 library regressions pass. The unchanged shipping CLI companion-mask/missing test passes, including actual human/JSON exits. Another 42 manager variants pass. 96 units across both scopes produce exactly four children, two per scope, all reaped; refused-resource regression passes. Actual systemd 249.11 accepts the exact property query (bus unavailable in its disposable container); full daemon checks use 257.Explicitly requested build-host replication, exact earlier recipe (50 alternating observations each, 3 warmups, real private server older than 11s): baseline p50/p99 20.253/49.940 ms; head 20.919/38.041 ms.

These are build-host observations, not perf-VM evidence. Both fixture PIDs gone; unit not-found/inactive.
The new live-mask P1 already posted remains independently reproducible. Untouched-target full gate and fresh sequential static sizes are running before test commits/final evidence.

R237-R3-01 stronger confirmation: repeated with a normal file-backed user service linked only in the runtime directory, then
systemctl --user mask --runtime --forcewithout --now. The real manager now explicitly reports LoadState=masked, ActiveState=active, SubState=running, MainPID=1760193, before AND after the complete CLI's false Stopped/exit-5 answer. This removes transient-unit precedence as a possible explanation. Same P1, no additional finding. Service stopped, runtime mask/link removed, daemon reloaded; not-found/inactive/MainPID=0 and PID gone.masked-active-linked.log
Gate setup correction: before the test row began, I detected that my 39-byte TMPDIR would make an existing daemon-gone rendezvous path exceed sun_path. Stopped only this review's own scope run-p1721500-i10107288.scope, retained the incomplete transcript, and restarted the untouched-target full gate with a real private one-character scratch directory (same setup used by the implementation run). No product/test change, no test failure or baseline exception claimed. Completed build cache is reused. The 126 matrix and previous-review regression checks already passed independently.
R237-R3-01 delta attribution: the identical new paired-headline regression PASSES against exact round-2 library source
324d0094eand FAILS againstf9859712c. With a live masked server, retained data and healthy companion, round 2 has overall=Active/confirmed_down=0 and the correct both-running headline; final has overall=Inactive/confirmed_down=1 and a false partial-down headline. This is the new headline/exit regression introduced by unconditional mask-to-Inactive accounting in329baf034. Earlier standalone masked-service discovery was already imperfect; I am not attributing every masked runtime blind spot to this patch. The real-manager reproduction separately establishes that masked+active is an ordinary reachable state, not fabricated properties.active-mask-delta.log

Round-3 review resumed after the earlier attempt hit a usage limit. Local branch review-status-crash-loop-237-r3 at
f9859712cf(still the target; nothing was committed before). I am continuing from the comments already posted here, and re-checking R237-R3-01 and its severity myself rather than taking it as given. The untouched-targetscripts/verify fastis queued in the build slot. Test development happens in a separate scratch checkout so the gate tree stays clean. No fixes, merges or deploys.Round-3 severity correction: R237-R3-01 is P2, not P1. Reproduced independently. The earlier "stop the lane" call is withdrawn, for three reasons:
324d0094ea masked, running standalone server with retained data already read Stopped/exit 5. The same test fails there:server user=false: Stopped / Inactive / down=1. Only the paired case changed, and round 2 got that one right only through its own R2-01 bug.masked_server_with_retained_data_is_not_described_as_runningasserts "a masked server cannot be running". Round 2masked_server_beside_a_running_host_has_a_partial_setup_headlineanswersActivity::Activefor the masked server and requiresStopped. The implementation followed that contract. A fix (query masked units and let a manageractiveanswer win) must change that round-2 fixture to answer Inactive for the masked unit, as a real manager does. That needs the orchestrator's OK, because those tests are meant to pass unchanged. The earlier attempt's draft delta test was not committed: it asserts the opposite of the round-2 test on identical input.systemctl maskwithout--nowon a running unit, and it lasts only until that process exits. The row detail says "service is masked", and the suggested next step (systemctl status) shows the truth.Evidence, real systemd 257 user manager,

329baf034| lib.rs:436-450, 265-269, 311-313. A masked canonicalinfraternal-agent.servicewith no other agent evidence now creates a host role that counts as down. A healthy server beside a masked agent unit prints "Part of this machine's setup is not running." and exits 5 (it was "The server is running", exit 0, on324d0094e). A machine with only the mask exits 5 as a down host instead of 0. D303 exits 5 for "something that should run"; a mask is the plainest statement that it should not. Retained server data is independent evidence of the server role; for the agent, the mask is the only evidence. This conflicts with the module-doc table's masked-agent column, so the table needs the owner's decision.Committed failing tests (review branch, pushed after the gate):

No shipping optimization/profile change is used for measured images. Runner/log paths remain/home/claude/j34-evidence/{build.sh,build.log}.

Current build still has no error; branch x86 compilation is active. The private same-filesystem fixture root/home/claude/Jwas created by this job (birth 2026-10-31T21:36:09+01:00), is mode 0700 and remains empty before the gate.J34 quiet perf-VM finding: a persistent median regression is reproduced on the requested perf VM.

57491e918and branch3ee792774, 5 repetitions × 50 alternating samples per image/scenario, 3 warmups/image each round, normal perf-run scope (CPUs 1–3, 6 GiB). Healthy harness is unchanged; crash variant keeps its timing loop and validates the intended state difference. 250 samples per image per scenario.Paired median head-minus-dev: healthy +0.695 ms (hierarchical bootstrap 95% CI +0.584..+0.836); crash-loop +0.724 ms (+0.610..+0.933). Every repetition has a positive paired median (healthy +0.507..+0.803, crash +0.667..+0.768). Resample rounds then within-round adjacent dev/head pairs; 10,000 draws, seed 23734. P50 is the median; p95/p99 nearest-rank. Tail spread will be included in the final receipt; these pooled tails alone are not treated as precise regression estimates.
All 20 before/after state files say
-- quiet: no process >5% CPU --; no warning. Hypervisor steal during runs is nonzero, 0.118..2.591% of all-CPU jiffies. Human/parsed JSON healthy outputs match; all crash-loop head samples report restarting/exit 5 while dev reports running/exit 0. All ten fixture cleanups report not-found/inactive/MainPID=0, with no retained fixture PID.Raw samples, logs and state files are now on control host
/home/kayg/.cache/codex-scratch/j34-test/perf/. A separate perf-run syscall trace is running to localize the median delay before the final merge recommendation. No implementation change is being applied. aarch64 builds, size attribution and fresh final fast gate remain in progress on compute01.J34 latency localization (no fix applied): five syscall traces per image, in a separate successful perf-run after the 1,000 timed samples. These traced observations are not included in the latency percentiles.
Both images make exactly one local manager query for the healthy old process; this is not a second-observation cost. Dev has zero sleeps. Head calls CLOCK_MONOTONIC clock_nanosleep 6–7 times/query, each about 1.07–1.09 ms under tracing. Child
exit_groupentry to successfulwait4reaping is dev median 0.278 ms (range 0.237–0.343), head 1.176 ms (0.380–1.440). This localizes a concrete avoidable delay consistent with the untraced +0.695/+0.724 ms paired median gap.Source attribution:

The bounded worker adds one thread in the trace; thread creation itself is ~0.06 ms in the shown trace, smaller than the completion polling delay.Proposed fix for the orchestrator, not applied: use deadline-aware child-exit readiness instead of fixed 1 ms polling, reusing the repository's existing polling API / audited exit-descriptor boundary. Preserve independent per-unit deadlines, manager isolation, fallible worker admission, kill-and-reap behavior, older-platform behavior, and the existing Unknown/refusal regressions; rerun these exact perf rounds and D243 builds on the candidate. No new library/engine decision is needed inside this measurement job.
A cheap size candidate is also visible on x86: the old
probehas#[inline(never)]with an explicit comment that its caller is speed-optimized and would copy its body; the newprobe_locallacks that attribute and has no standalone nm symbol.infraternal::status_resultgrows 13,264 bytes, while the old out-of-lineproberemoves 5,522 bytes. Mirroring the existing inline boundary onprobe_localis a narrow candidate to measure, with no semantic rewrite. Savings are not measured or claimed; no code was changed. Full aarch64 attribution and the fresh fast gate are still pending.The diagnostic before/after files also pass quiet checks (all 22 state files, including the 20 timed-run files, report quiet; no warning). Traces/summary are retained on control host under

57491e918vs branch3ee792774, both targets built on compute01 through the same normal build slot, one shared target directory, identical shipping release/static recipe. All four images have no PT_INTERP. Fresh sizes reproduce #71602 exactly.Exact file-byte attribution from ELF sections:
The .relro_padding changes (+2,304 / +80) are NOBITS and do not add file bytes. Symbol attribution used
nm --size-sort --print-size --radix=d --demangleon a second final-crate build with-C strip=none. For all four images, .text/.rodata/.eh_frame/.data.rel.ro bytes are identical between shipping and symbol-retaining files; hashes are saved. GNU nm assigns an inferred size to ARM's zero-sized _start; the analysis filters against positive STT_FUNC st_size in the ELF .text symbol table and de-duplicates aliases. This avoids counting that synthetic overlapping range as growth. Union of defined function bytes grows +13,111 / +19,404; remaining .text gaps/alignment change -55 / -76.Selected function-body deltas explain the status work and its inlining footprint:
Status-named code including its type specializations is 23,246→25,357 B x86 and 20,316→22,584 B ARM. Adding status_result gives +15,375 / +12,760 B; other defined functions net -2,264 / +6,644 B. Those remaining changes include common process-output/thread/iterator/drop paths and whole-program code-generation effects (ARM examples: TypeId hash-table rehash +1,828 B, existing server CLI plugin +696, server input metadata +448, process read_output +568). They are not additional product features; the shipping-source diff is confined to status, its CLI envelope/dispatch, and its existing nix/time feature request. Full sorted symbol deltas and exact section/hash receipts will be attached with the final report.
Written reason for the aarch64 16–64 KiB band: +24,496 B is 8,112 B above 16 KiB and below 64 KiB. These bytes buy seven-property local observations, monotonic restart-age checks and immediate consecutive observations for fresh processes; independent fallible bounded query workers so one unavailable manager/unit cannot erase another's state; truthful configured-role/headline/D303 exit behavior for crash loops and masks; and scoped repair/journal guidance capped at three Next items. They retain correctness under refusal, timeouts, historical restart counts and mixed roles. There is no new library or engine, version change, or shipping release-profile change. Status explicitly requests existing nix/time, already used elsewhere in the full shipping dependency graph. The reason covers the whole branch, not only the final masked-role fix round. The 1 ms completion-polling overhead found separately is avoidable and is not justified by this size reason.
Cheap reduction candidate, not applied or measured: put the same
#[inline(never)]boundary onprobe_localthatprobealready has. The existing comment explicitly prevents copying a size-optimized body into its speed-optimized caller.probe_localcurrently has no standalone symbol and status_result grows 4,090→17,354 B x86 (+13,264); its ARM caller grows +10,492. This is a narrow, behavior-preserving candidate to build/benchmark before accepting any claimed saving. No saving is promised from raw symbol sizes alone because inlining and link layout are non-additive.Current recommendation remains DON'T MERGE due to the reproducible latency regression, not the documented size band. No code fix or cap change was applied. The fresh scripts/verify fast is running on clean head
3ee792774; final gate output, attachments and target cleanup follow.J34 size refinement: ARM's +4,096 B .rodata change is largely layout/padding rather than 4 KiB of new diagnostic text. Counting the actual shipping section bytes gives net +1,097 nonzero bytes and +2,999 zero bytes; zero runs of at least 64 bytes grow by 2,962 B. On x86 the .rodata section size stays unchanged, with +1,043 nonzero / -1,043 zero bytes. This is consistent with the small added constants consuming existing padding on x86 and crossing an ARM layout boundary. The section accounting in the previous comment remains exact.
rodata-analysis.jsonwill be included in the final evidence archive.The fresh fast gate has passed CLI compile-out and is now in clippy, with no gate failure reported. All shipping/source/symbol artifacts and both measurement findings are already saved on control host. No implementation change, merge or deployment.

Measurement-only worktreej34-test-measurement; no implementation edits, commits, push, merge, deployment or issue closure.recommendation: DON'T MERGE this head yet. The quiet-VM measurement reproduces an avoidable median latency regression. The aarch64 size band has a written, measured reason, but that does not justify the completion-polling delay. Proposed fixes below were not applied.
Latency: fresh pinned stripped x86 images built on compute01 through build-slot, copied to the requested perf VM. Existing healthy 50-run harness unchanged; crash variant adjusts state validation and fixture admission, records the differing output, and preserves the timing loop. Five repetitions per scenario, 3 warmups per image/repetition, 50 alternating dev/head observations each: 250 samples per image per scenario, 1,000 timed CLI observations total. Healthy private server age ≥11 s; actual immediate-failure Restart=always service, 200 ms restart delay, admitted after ≥3 restarts. Every run used perf-run, CPUs 1–3, 6 GiB cap.
Values are pooled ms; brackets are min–max of the five repetition percentiles. p50 is median; p95/p99 use nearest-rank.
Paired median head-minus-dev: +0.695 ms healthy (hierarchical bootstrap 95% CI +0.584..+0.836), +0.724 ms crash-loop (+0.610..+0.933). Every repetition's paired median is positive. Bootstrap resamples repetitions, then within-repetition adjacent dev/head pairs; 10,000 draws, seed 23734. The tails overlap substantially and are not assigned the same confidence as the median gap.
All 20 timed-run before/after state files say
-- quiet: no process >5% CPU --; no warning. Load starts at 0.00/0.00/0.00 and stays below 0.49 in the one-minute field. Nonzero hypervisor steal is disclosed: 0.118–2.591% of all-CPU jiffies over each run. VM exposes 4 vCPUs, Ryzen 7 3700X, Linux 6.12.113+deb13-amd64; no cpufreq governor visible. Both diagnostic state files are quiet too (22/22 total). Healthy human output is byte-identical and parsed JSON equal. Every measured crash-loop head result is restarting/exit 5; dev incorrectly returns running/exit 0. All ten fixtures were stopped, their unit removed, and MainPID=0/not-found/inactive verified.Localization: five additional syscall traces/image in a separate perf-run, excluded from the timing statistics. Each image makes one local manager query for the old healthy process. Dev has no sleep calls; head has 6–7 ~1.08 ms clock_nanosleep calls. Child exit_group-entry to successful wait4 reaping: dev median 0.278 ms (0.237–0.343), head 1.176 ms (0.380–1.440). This directly observes delayed completion polling consistent with the untraced median gap. It does not claim that a proposed replacement has already recovered that time.
The loop is
manager_propertiesincrates/infraternal-status/src/lib.rs,try_waitplusthread::sleep(Duration::from_millis(1)), introduced by5860ab6fd. Proposed, not applied: deadline-aware child-exit readiness using the existing polling/exit-descriptor boundaries, preserving independent deadlines, admission/refusal behavior, kill/reap and older-platform behavior. Benchmark and run the existing regressions on that candidate before accepting it. Detailed localization.Fresh D243 sizes, all static/no PT_INTERP:
Written size reason: ARM is 8,112 B above 16 KiB and below 64 KiB. The added code buys monotonic seven-property restart observations, bounded independent manager/unit query ownership, truthful configured-role/runtime/headline/exit behavior, and scoped repair/journal guidance within the three-Next budget. No new library, version or shipping profile change. The status crate explicitly requests existing nix/time, already used elsewhere in the shipping graph. This reason covers the whole branch.
Exact section accounting and both-architecture nm deltas are recorded here and in the archive. .text grows +13,056/+19,328 B; ARM .rodata adds 4,096 B (net +2,999 zeros/+1,097 nonzeros, largely padding/layout). Shipping and symbol-retaining images have byte-identical .text/.rodata/.eh_frame/.data.rel.ro on all four builds; hash receipts are included. Symbol totals exclude GNU nm's inferred extent for ARM's zero-sized _start and deduplicate aliases against the ELF symbol table.
Cheap size candidate, unmeasured and not applied: mirror the existing
probe#[inline(never)]boundary onprobe_local. The documented reason already says a speed-optimized caller would copy the body. New probe_local has no out-of-line symbol; status_result grows +13,264/+10,492 B while the old probe removes 5,522/4,744 B. An outline boundary is a narrow candidate, but those symbol deltas are not promised savings.fresh final gate:

the evidence archive contains raw observations, all 22 quiet-check state files, separate syscall traces, percentile/bootstrap summaries, harnesses, build receipts, both-architecture nm/section output, attribution, and the full gate log. the pending action is a narrow completion-wait fix and a fresh paired benchmark before merge; the optional outlining candidate also needs measurement.

b5d823923: completion polling is removed on this VM, confirmed by five head syscall traces: one pidfd_open each, zero sleep calls, readiness poll followed by wait4. All 22 before/after snapshots are quiet, zero warnings. The exact alternating 5×50 harness gives 250 observations/image/scenario. Paired head-minus-dev median is healthy +0.030 ms, hierarchical-bootstrap 95% CI −0.051..+0.160; crash-loop +0.193 ms, CI +0.106..+0.277. This improves on J34 +0.695/+0.724 ms but the crash-loop target is not met; do not merge on this evidence. All measured outcomes were valid (healthy identical human/JSON, crash head restarting/exit 5 versus dev running/exit 0), all eleven fixtures cleaned to not-found/inactive/MainPID=0. Hypervisor steal across the runs is 0.116–4.383%; tails are variable and not assigned the median CI. An identical second batch is now running to test reproducibility; the first batch is preserved in full, and both batches plus pooled results will be reported. First raw evidence and summary:~/.cache/codex-scratch/j40/perf/evidence/on control; perf VM first batch is~/j40-perf/evidence-first/. Fresh x86 head is 21,443,824 B, +12,352 versus dev and −1,728 versus the prior branch image. ARM and the final fast gate continue on compute01.J40 gate setup finding: the first full

Same J34 Python harnesses, alternating dev/head, 50 pairs per repetition, 11-second fixture settling, perf VM only through
perf-run. No product changes between batches.Pooled dev/head p50/p95/p99: healthy 9.447/13.557/15.994 -> 9.446/13.544/17.287 ms; crash-loop 9.129/11.647/14.164 -> 9.273/12.916/16.829 ms. Paired repetition medians span -0.031..+0.102 ms healthy and +0.025..+0.219 ms crash-loop. Per-image repetition p50 spans dev/head 8.806..10.111 / 8.853..10.180 ms healthy; 8.678..10.050 / 8.657..10.023 ms crash-loop. Raw per-repetition p95/p99 and all samples retained.
Quiet evidence: all 42 selected before/after snapshots are quiet (includes first-batch diagnostic trace). An additional healthy confirmation round flagged 5.9% background netbird CPU before measurement; retain it and repeat that round without changing code. All 44 snapshots retained, 43 quiet. Including the flagged round instead of its replacement gives confirmation healthy +0.050 [-0.064, +0.150] ms. Every crash-loop snapshot was quiet. Five head traces each contain one pidfd_open and zero sleeps, versus zero sleeps on dev. Healthy human/JSON equivalence and crash-loop head Restarting/exit 5 are asserted by the unchanged harness; dev incorrectly says Running/exit 0.
D243 four fresh stripped static builds on compute01 through build-slot: dev x86/arm 21,431,472 / 19,605,896 B; head 21,443,824 / 19,629,240 B. Delta +12,352 / +23,344 B, down 1,728 / 1,152 B from the previous branch. All four ELF receipts have no PT_INTERP. Exact caps ratcheted down; ARM written reason retained in docs/PROCESS.md. Measured shipping tree is identical at final head (only caps/docs/message followed the measured code).

Corrected full gate queued through build-slot (controller PID 2383760); it refuses an admission while the prior gate PID 1637507 is still alive, releases that admission and waits outside build-slot before requeuing, so the target is never used by two J40 gates. Prior gate source remains untouched until it finishes. Current workspace tests continue passing; only the known clippy failure has been recorded. Shipping hash identity versus measured images will be checked after the final gate; rerun performance if hashes change.J40 checkpoint: pushed head
4cd62891a2d0f54e8ae166cb59f289009df701dcremains clean. The complete c311 gate finished: all rows passed except the known clippy single_match_else error; full log is attached to 72164. The equivalent if-let correction is in 4cd. Its full retry remains queued through build-slot, live position 3 (controller 2383760, slot waiter 2383762); it started at 14. No simultaneous J40 target use. Only target/home/claude/worktrees/j40/targetretained for retry + shipping hash audit. Perf VM already cleaned. No new latency claim for 4cd until shipping image hashes are compared with measured copies after its gate.
