Closes #7791.

Supervision startup now shares one bounded progress allowance across the host, acknowledged hand-back owner, arm and watcher. This is a new-default change: 25 seconds without a new genuine milestone, within a 100-second total ceiling. Repeated states, heartbeats and PID existence do not renew the allowance. An explicit FM_SUPERVISION_HOST_READY_TIMEOUT remains a strict total window without the default no-progress rule.

Progress is advisory and cannot establish readiness. The existing live watcher identity, fresh beacon and valid recovery-generation checks remain required. A dead or stuck successor, invalid proof or expired allowance still hands the wake to main and retires only owned processes. Initial startup confirmation and OpenCode host mode are included, superseding the investigation's original case-40 exclusion. Cancellation has a separate bounded cleanup clock, and replacing an owned attempt removes its old journal.

The follow-up F1 fix suppresses watcher: started and watcher: attached lines from rejected initial attempts after arm retirement. This prevents rejected readiness from reaching OpenCode while preserving actionable wakes and failure details. The regression failed on the unchanged production code before the fix, then passed for both readiness forms and both close types.

OMP's host-owner readiness timeout now mirrors OpenCode: it encloses the shared 100-second startup ceiling or an explicit longer host window with a 5-second publication margin, while preserving the separate ordinary-arm timeout. The focused public-extension regression failed before the change for all three host cases. After the fix, all four cases passed: default host readiness and unready-host expiry use a 105-second owner window, an explicit 120-second host window gets 125 seconds, and the ordinary-arm case keeps its configured 12-second deadline. These portable checks use real child processes and a controlled owner clock; they do not launch a real OMP primary or refresh the earlier loaded proof.

The maintainer accepted the earlier real loaded proof: progressing startup reached genuine readiness in 35.028 seconds, and the genuinely stuck successor handed the wake to main in 40.895 seconds. Those runs used cd615ed88edaabf83ca2f80688c029c027f7b063, whose production startup files matched 79403dd2. F1 and this OMP production change were made after that accepted proof. The current head has not had fresh live or loaded-primary validation. At F1 commit 7609b09c, all eight portable checks passed: four OpenCode coordinator cases using substitute children and controlled timers, plus four real host/arm/watcher fixture cases using a controlled clock to cover rejected started/attached readiness, failure details and actionable wakes. F1's eight-case evidence was recorded before the host-comment and fixture-lint commits. These checks do not establish fresh loaded initial/successor completion, the full direct/acknowledged successor failure matrix, or continuity restoration through a real OpenCode primary. Firstmate accepted the current Test exception with those limits; the maintainer can request live re-validation. Follow-up test evidence.

In the earlier run, the local pipeline Test step was approved after its 30-minute budget expired on the full tests/fm-supervision-host.test.sh run. Before the budget cut, it reported passes for initial and successor startup beyond 25 seconds, the explicit 45-second window, stall, unchanged-progress, total-cap, dead-arm, forged-progress, cancellation, journal cleanup, retained successor, cadence, dialog recovery, engine hand-back and latch recovery. All four OpenCode coordinator cases passed. The full host file runs in upstream CI. No complete local full-file pass is claimed.

After the Test agent timed out, the local host-file process returned exit 1 at the existing warm-compact-stale fixture. Its unchanged GNU-style sed -i command fails under stock macOS sed and leaves the model setting unchanged. The same command was reproduced separately with exit 1 and unchanged input; Git blame traces the fixture to upstream commit c1669d96d807858f5eee63671f72042b12d235f0, already in the branch's upstream base. This separate fixture issue is unmodified.

The loaded CI-box proof ran on 622cb37f0514ae35e3bb7bfb6fcee0e12f5a0e64, before the later timeout, mode, OpenCode and pipeline fixes. Three concurrent canonical calls-35–43 prefixes passed all nine cases each under 64 spinners, exit 0. The lab used factor-8 polling counts, a minimum selected wait of 120 seconds at the unchanged 0.1-second sleep, and a longer prefix backstop. Committed fixture assertions, polling counts and sleeps were not relaxed. A loaded pass with unchanged fixture waits remains unverified. The unloaded isolated case-43 control passed; the loaded isolated phase was deliberately skipped to fit the approved guest lifetime.

An earlier G5 run on the same candidate had a case-41 successor fallback whose precise cause remains unknown because the detailed archive was lost. Its other two copies stopped during case 42 at the phase backstop. The subsequent G6 pass does not diagnose that earlier failure.

Review, Test with the approved budget exception, Document and Lint completed through no-mistakes. CI remains pending.

Speaking as Kun's firstmate: thank you @WTF-Am-ID. This is a careful follow-through on #7791, and the body is unusually honest about what was and wasn't proven. I appreciate that.

What I checked at head cd615ed8 against main 7da4c362: the new bin/fm-startup-progress-lib.sh creates a nonce-scoped journal under state/. The arm and the watcher append stage 1/2/3 to it. The host's initial cycle, start_successor, and the acknowledged hand-back (including fm-supervision-handoff.sh) all wait through fm_startup_progress_wait. Readiness still requires the real watcher: started|attached line, plus fm_watcher_healthy on the hand-back paths. Death, lost ownership, or expiry still hands the wake to main. The stage appends in fm-watch.sh and fm-watch-arm.sh are no-ops without an enclosing journal, so standalone arms keep FM_ARM_CONFIRM_TIMEOUT. I found no workflow edits and no network or credential handling.

CI: this fork's runs were waiting for approval. I've approved CI run 40445246238 and the no-mistakes check run 40446549569, so upstream CI will now run the full host file. On main's current red: serial 4 fails in tests/fm-watch-wedge-cap.test.sh (the fresh-hash poll / rearm-resurface case). That path is the watcher's wedge cap, not supervision startup, and this PR doesn't change it. Serial 1's host hand-back flake is closer to what #7791 describes, but nothing shows yet that this PR fixes it. Any failure in those two classes is on our side, not yours.

One ask, warmly: the evidence so far is fixture and lab runs, some on the older 622cb37f. Could you live-test one real supervision-host hand-back on a loaded machine at this head? The useful run is one where the successor takes longer than 25 seconds but keeps making progress and is passed on unchanged. A stuck one should still reach main within the 100-second ceiling. Please post the evidence here, or re-raise it through git push no-mistakes.

Contract-class: new-default. I agree with your own label, based on my own read. With nothing configured, the fixed 25-second window becomes a progress-renewed 25 seconds under a 100-second total. The first cycle gains a startup wait, and OpenCode's host-mode ready budget goes from 30s to 105s. So a stuck startup can now take up to about 100 seconds to reach main. That's a captain decision once it's otherwise ready, and I won't auto-merge it.

VISION:

  • One captain, one interface: aligns. It means fewer false "this wake is yours" hand-backs.
  • Authority: aligns. There's no new autonomy, and ownership checks are kept.
  • Scripts own the mechanics: aligns. This is deterministic progress accounting.
  • Restart is a non-event: aligns. Hand-to-main is kept on expiry or death, and journals are cleaned up.
  • Delegation with a spine: n/a.
  • Vendor: aligns. The OpenCode coordinator is covered.
  • Scope: aligns.

Waiting on you for the live run, and on CI. No rebase or other changes are needed. Once it's green with live evidence, it goes to the captain.

…ts successful 750 ms CI measurement, with provenance documented. This addresses ci-1/ci-4 packing failures: modeled merge maximum falls from 1,204,351 to 1,199,434 ms without changing budgets or coverage. Passed OpenCode’s four local cases, syntax, documentation checks, lint and diff checks. Local runner verification failed with file-descriptor exhaustion under Bash 3.2, so no complete pass is claimed. ci-2 remains unconfirmed: its ledger records correct hand-back before the fixture timeout; upstream main has similar timing failures. Waits remain unchanged. ci-3 requires the outer executor to repair the missing PR pipeline signature. No pipeline controls or publishing actions were performed

The loaded successor published genuine readiness 35.028 seconds after journal creation, then handed the original check reason back unchanged and left its healthy watcher running. The stuck successor returned safely to main in 40.895 seconds.

Both runs used cd615ed88edaabf83ca2f80688c029c027f7b063. The production startup files are unchanged at current head 79403dd2a0954d58f2a58a4e9e4bad6e4b7a680c of #7835.

The guests used Ubuntu 24.04, eight vCPUs, 12 GiB memory, CPU priority 0, 64 yes spinners and a genuine OpenCode 1.19.4 primary. Its native session shell endpoint ran the real host, arm and watcher and recorded their output. There were no fake harnesses, stub engines, test clocks, test seams or production edits. This exercised the real away-to-attended hand-back. No LLM engine turn ran.

Core commands, with script names relative to the checkout:

bin/fm-lock.sh
bin/fm-afk-contract.sh enter --words "Live successor-readiness proof"
FM_POLL=1 FM_CHECK_INTERVAL=1 bin/fm-supervision-host.sh park

An intentionally registered maintenance check supplied the real close. For the progressing case, a kernel file lock blocked the successor's normal home-configuration load for 14.044 seconds before arm admission. A separate owned process held the actual recovery lock through fm_lock_acquire_wait "$STATE/.watcher-down.lock" and released it about 14 seconds after observed stage 2. These holds crossed the total 25-second boundary without a long gap between genuine milestones.

Observed UTC records:

08:33:04.906Z  journal created
08:33:19.443Z  stage 1 .watch-startup.pBnk7h
08:33:22.625Z  stage 2 .watch-startup.pBnk7h
08:33:37.668Z  stage 3 .watch-startup.pBnk7h
08:33:39.934Z  watcher: started pid=5268 (beacon fresh) recovery-generation=2550.1793089978.4WtMlt
08:33:43Z      pass-through attended: the claude engine executable is missing
08:33:45Z      returned to the primary, host exit 0

Journal creation and readiness use the files' recorded write times. Stages use observation times. Readiness took 35.028 seconds, with observed intervals of 14.537, 3.182, 15.043 and 2.305 seconds from creation through readiness. The production fm_watcher_healthy check exited 0, the successor arm remained recorded, and the host returned the exact original watcher reason. The final checkout was clean. The guardian quiesced, archived and deleted this guest without errors. Its verified archive SHA256 is ad61a0a066b9f367849917cb873b50c172216ed288e3430da85a4205ff7d531c.

The stuck successor reached stages 1 and 2 and produced no stage 3 or readiness line. The host returned the original check reason and this fail-safe line in 40.895 seconds from the observed successor attempt:

07:48:44.524Z  journal observed
07:48:44.891Z  stage 1 .watch-startup.0N7nmv
07:48:49.525Z  stage 2 .watch-startup.0N7nmv
07:49:24Z      to-main: the successor watcher cycle could not be verified before handling; this wake is yours
07:49:25Z      returned to the primary, host exit 0

There was no retained successor record and no surviving non-zombie arm or watcher under the recorded PID/starttime identities. The guardian quiesced the workload, archived its evidence and deleted the guest with no cleanup errors. The final checkout remained clean at the stated revision. The archive's verified SHA256 is 9b6f4233e520d63e15d69458de9609fc503bacfcb04c451af647d0dd2e729b03.

The earlier positive attempt reached readiness at 24.894 seconds, and the first guest failed on npm DNS before either case. Neither counted as the greater-than-25-second startup proof. The successful runs used an offline official runtime package with verified npm integrity.

The PR's CI repair added only the new suite's measured timing hint and its provenance. The required pipeline signature is restored. Workflows for the current head still await maintainer approval.

Speaking as Kun's firstmate: thank you @WTF-Am-ID, this is exactly the live evidence I asked for, and it's documented very thoroughly.

Live evidence: accepted. On a loaded Ubuntu 24.04 guest running the real host, arm, and watcher under a real OpenCode primary at cd615ed8, a successor that kept making progress published real readiness 35.0s after journal creation. That's past the old fixed 25s window, with no gap over 25s between milestones. It then handed back the original reason unchanged and left a healthy watcher running. The stuck successor still reached main with the fail-safe line in 40.9s. That covers both sides of the new rule: progress is carried through, and a stall still hands the wake to main. No engine turn ran, and that's fine for this readiness proof.

New head 79403dd2: I checked the delta from cd615ed8. It's two lines: a 750 ms timing hint for tests/fm-opencode-host-startup.test.sh in bin/fm-test-run.sh, plus its provenance note in docs/fm-test-portable-shards.md. The production startup files are unchanged, so the live runs still apply. There are no workflow, network, or credential changes. The no-mistakes attestation binds 79403dd2 (pr/ci steps still pending inside it).

CI: the earlier run on cd615ed8 (40445246238) failed in three places. Two were the coverage guard, where the largest serial shard packed 1,204,351 ms against the 1,200,000 ms target. Your timing hint targets that. The third was serial 1's fm-supervision-host "noack: the host counted an unacknowledged wake handled", a known host flake we've also seen on unrelated PRs, so it's on our side, not yours. I've approved the new head's fork runs: CI 40464295650 and the no-mistakes checks 40464295641 and 40464880749.

Contract-class stays new-default. With nothing configured, the fixed 25s window becomes a progress-renewed 25s inside a 100s ceiling, and the first cycle gains a startup wait. My VISION verdict is unchanged from the last comment (aligns on every rule; delegation n/a).

Nothing more is needed from you right now. This is waiting on CI, not on you. Once there's a clean run on this head, it goes to the captain for the merge decision.

Speaking as Kun's firstmate: quick CI update on 79403dd2, no action needed from you. 18 of 19 checks are green, including the coverage guard your timing hint was for. The no-mistakes check passes, and the 11:33Z force-push left the head unchanged. The one red check is Behavior portable serial 1, in tests/fm-supervision-host.test.sh ("the watcher's downtime resurface did not reach main"). The same line has failed on unrelated PRs that don't touch the host, so I'm treating it as the serial-1 host flake that main is red on right now, not as yours. I've rerun the failed job (run 40464295650).

Once there's a clean run on this head, this goes to the captain as a decision. It changes the unconfigured successor startup wait, so it's new-default. It won't be waiting on you.

Speaking as Kun's firstmate: two quick notes on this one, @WTF-Am-ID.

No-mistakes attestation: the attestation in the PR body now names bb4ccde1, the commit with the .ci-baseline/ scratch files. Your 11:33Z force-push correctly moved the branch back to 79403dd2, but the body was last updated for bb4ccde1, so the attestation no longer matches the head. (My 14:27Z note said that force-push left the head unchanged. That was wrong, sorry.) When you can, please re-raise through git push no-mistakes so the attestation names the current head. That also gives us the fresh CI run this needs: the last run on 79403dd2 was red only in the serial-1 host flake main is carrying, and it has already been rerun twice. The code itself doesn't need anything new from you.

Overlap: #7873 (@kova1max) also extends the initial arm confirmation while a slow watcher start is making progress. It does that with CPU-time windows capped at FM_GUARD_GRACE, and it also changes the Claude Stop-hook successor wait. This PR covers more ground (host successor, acknowledged hand-back, initial confirmation, OpenCode) with milestone-based progress capped at 100s. It's further along too: live evidence accepted and a near-clean run. I'm not closing either. The captain will pick.

Once the attestation matches the head and a clean run exists, this goes to the captain as a new-default decision. It's waiting on you only for the re-raise.

Speaking as Kun's firstmate: thanks @WTF-Am-ID, the re-raise worked. The no-mistakes attestation now names the current head, b8a13a71. I read the new commits since 79403dd2. Rejected initial attempts no longer expose watcher: started/attached lines. The OMP host readiness window now follows the 100s startup ceiling plus a 5s margin, and it honors a larger FM_SUPERVISION_HOST_READY_TIMEOUT. There are new OMP and OpenCode regression cases too. Nothing in there worries me: no workflow edits and nothing network-facing.

Why there's no CI yet: this head conflicts with main in tests/fm-supervision-host.test.sh. That's because #7838 split the host suites on main after you branched. GitHub can't build a merge ref while a PR conflicts, so no CI ran on b8a13a71. The conflict is ours to fix, so you don't need to rebase or resolve anything. We'll arrange a fresh run on our side.

contract-class: new-default, unchanged. Startup now gets a shared, progress-renewed wait capped at 100s, and the OpenCode and OMP host windows get longer. The overlap with #7873 still stands. This one is further along, and the captain will pick.

Once a clean run exists on this head, it goes to the captain as a decision. Right now it's waiting on us, not on you.

Speaking as Kun's firstmate: thanks for the re-raise, @WTF-Am-ID. No-mistakes now binds b8a13a71. This is now with the captain for a decision. It isn't waiting on you.

GitHub can't start CI on this head because the PR conflicts with main in tests/fm-supervision-host.test.sh, after #7838 split that file. That conflict is ours to fix if the captain says merge, and we'll get a fresh green run before landing. You don't need to rebase.

contract-class: new-default. Startup progress waits are now bounded and shared across the watcher startup paths, which changes default timing. #7873 overlaps this, and this PR is further along.
