M3 — steering foundations: expected-tip CAS, host identity, Codex session fixes - #24

Conversation
…charter M3 M2 closed with two deferrals named in ADR-0018's Consequences: a follow-up produces a patch but can never push (publication is a creation CAS by ADR-0012 design), and central host affinity bounces for five minutes before failing honestly. M3 promotes both, plus the three unchecked M2 craft boxes, into docs/plan/m3-plan.md. ADR-0019 generalizes the publish CAS from creation to tip advance: E = the chain's last published snapshot (runs.published_sha), parent selection instead of rebase (the base never moves, evidence stays cumulative), force-with-lease from E, typed publish_conflict on anything else — a human push to the branch always wins. The synthetic publish tail is always approval-gated: the ancestor's approval covered the ancestor's bytes. Amendment pointers appended in ADR-0012 (CAS generalization) and ADR-0018 (both deferred Consequences resolve; host-affinity decisions locked 2026-08-16: initial-run resumes route host-bound too, scratch follow-ups stay non-host-routed this milestone).
…ith it ADR-0018's Consequences recorded the bug: the Codex session home was keyed by workspace (fixed in M2) but still lived under OS tmp — the OS could reap a chain's resume threads mid-steering, and nothing ever collected them. The home is now `<workspaceDir>.codex-home`, the same sibling convention as the `.platform` sidecar, and removeWorkspace removes it — so the worker collector and the daemon reap both enforce session-lifetime-equals-workspace-lifetime without knowing the suffix. Pre-upgrade sessions sit at the old tmp path; the first follow-up after upgrade resumes unverified and takes the engine's context-loss disclosure path (window: one retention hour). Both new tests verified by reverting each half of the fix and watching them fail.
Codex review round 1, three findings, all verified valid:
1. ADR-0019's tail guard skipped the whole tail when the patch matched
the chain's last APPROVED patch — conflating approved with
published. A chain whose push failed transiently (or whose pr.open
died post-push) could never complete delivery: the next unchanged
follow-up skipped past it forever. Decision 3 restructured: whole
tail skips only on an empty cumulative patch; the checkpoint alone
skips on byte-identical re-approval (approval attaches to bytes and
carries forward); push/pr.open always run — both idempotent — so an
approved-but-unpublished chain completes. Locked decision 2's intent
holds: no bytes ever push without a chain approval covering exactly
those bytes.
2. R1 made the followup endpoint's exemption rationale ("sessions do
not expire with a filesystem") false for one class: a workspace-less
chain's Codex project-credential session home is now collected with
the scratch workspace at retention. Stance recorded rather than
mechanism changed — an independently-retained home would recreate
the never-collected leak R1 fixed. A late follow-up still runs and
degrades honestly (disclosure + parent outputs); comment corrected.
3. The fix's claims overreached its mechanism: the sibling home exists
only under a project credential — ambient-auth flows keep the
executor's own home because that home IS their auth source.
CHANGELOG and design 03 scoped; a new test pins the ambient
contract (revert-verified by making the redirect unconditional).
…not model_error Codex review round 2, four findings, all verified valid: 1. (P1) When the CLI dies before thread.started while resuming — a collected or migrated session home; reproduced live against codex-cli 0.147.0: empty stdout, stderr "no rollout found for thread id … (code -32600)", exit 1 — the adapter yielded step.failed(model_error). The engine's context-loss disclosure runs only on a non-failed invocation reporting resumed:'rejected', so the step burned retry budget re-offering the dead session and the run failed. Any pre-start death during a resume now reports the rejection: the engine aborts that invocation and re-invokes fresh with the disclosure. A cause that is not the session (bad auth, bad flags) recurs identically on the fresh start, where model_error still surfaces — one process-start later, honest both ways. New fixture scenario pins the real stderr shape; the rejection test is revert-verified. 2. (P2) m3-plan's P3 verify line still said "empty/no-change steers skip the tail" — round 1 fixed the implementation bullet but left the criterion that would have encoded the approved/published conflation into the compliance test. 3. (P2) design 05 still said sessions "do not expire with a filesystem"; the R1 plan bullet was unscoped and used 'unverified' (a capability level) for what the protocol calls a rejected resume. 4. (P3) executor tests leaked one .codex-home sibling per workspace (45 accumulated in tmpdir); cleanup now removes the sibling too.

ADR-0019 P1: publication's compare-and-swap grows a second admitted state. With no expectedTip the behavior is unchanged (branch absent, or already the deterministic commit). With one — the chain's last published snapshot — the new commit parents on it (evidence is cumulative against the unmoved base, so tip advance is parent selection, not rebase), the push force-with-leases against exactly it, and determinism extends to the new input: (base, patch, expectedTip) fixes the commit SHA, so retries stay idempotent across every crash window. Any other observed tip — diverged, or an absent branch the chain says it published to (deleted after merge, force-pushed away) — refuses as a typed TipConflictError carrying the observed tip, and the remote is never overwritten: a human push to the branch wins by default. A no-op guard returns the expected tip without pushing when the approved tree already IS its tree, so a steer that changed nothing never mints an empty tip advance (pushed: false tells the caller which happened). Real-git tests cover advance/idempotent-retry/no-op/diverged/deleted; the advance and no-op tests verified by neutering their logic and watching them fail. Engine wiring (published_sha, PushResult tip_conflict) is P2.
ADR-0018 amendment, slice A1 of the per-host queue. Host identity is the identity of the WORKSPACE storage, not the container: a uuid minted once at WORKSPACE_ROOT/.agrippa-host-id (exclusive-create, so replicas racing on a fresh volume converge), shared by every replica mounting the volume — a redeploy never looks like a new host. Plumbing, all additive (migration 0033): runs.workspace_host is stamped first-writer-wins at repo checkout — with a DB-enforced runtime_id IS NULL guard, so a daemon-routed run can never acquire a central host pin whatever path led to checkout — and inherited by follow-up inserts like the workspace key it accompanies. worker_heartbeats.workspace_host advertises which host a live worker serves; it becomes the liveness source for A3's dead-host sweep and the queue key A2 routes by. Scratch runs deliberately do not stamp (non-host-routed this milestone, per the locked scope). Nothing routes by the column yet — that is A2. All five new tests verified by neutering their behavior and watching them fail.
…nswer for the observed tip Codex review round 3 on P1/A1, three findings, all verified valid: 1. (P1) workspaceHostId's exclusive-create write was open-then-write: a concurrent boot could read the file between creation and content and adopt the empty string — which silently disables host stamping (truthiness guard), and which the convergence test could not catch because two empty reads are equal. Contents now land under a temp name and link(2) publishes them: the final name either does not exist or is complete. Empty after create throws loudly. The concurrency test now asserts id SHAPE, not just convergence. 2. (P1) The no-op guard returned the expected tip without observing the remote: an unchanged steer on a branch a human had advanced reported stale success over a remote the chain no longer describes. The guard now holds only while the observed tip IS the expected tip and refuses typed otherwise. ADR-0019's no-op sentence corrected — the same lesson as round 1, again: a guard that skips a verification step. The first test written for this accidentally exercised the missing-parent path (moving the ref to base makes E unfetchable); the committed test constructs a DESCENDANT human commit so the refusal provably comes from the guard. 3. (P2) A lease lost between ls-remote and push escaped as a generic git error the engine cannot type. The push now re-observes on failure: tip moved → TipConflictError; tip unmoved → the real error rethrown, so a transport failure never masquerades as a conflict. Covered by a two-racer test (exactly one lands, the loser conflicts typed whichever window it hit) and a read-only-remote test pinning the not-a-conflict side. All deterministic new tests neuter-verified.

Preserve the active link's host pin.
When activeLink exists, parentRunId points to that row, but Line 938 copies parent.workspaceHost. A legacy or partially stamped ancestor can be unpinned while the active follow-up already has a host. The new run then bypasses host routing and can be claimed by a worker that cannot serve the workspace.
Select workspaceHost with activeLink and prefer it, with parent.workspaceHost as a fallback. Add a regression test for steering an ancestor while a pinned follow-up is active.
Proposed fix
- .select({ id: runs.id })

| ## Amendment (2026-08-16, M3 — the two deferred Consequences resolve) | ||
|
|
||
| - **Publication from a follow-up is now specified by ADR-0019**: the expected-tip CAS this ADR asked for, plus a synthetic publish tail on which no bytes ever push without a chain approval covering exactly those bytes — the ancestor's approval covered the ancestor's bytes, so a steer re-presents the cumulative patch before any push (a byte-identical re-presentation carries the earlier approval forward rather than re-asking, and the push/PR steps still run so an approved-but-unpublished chain completes its delivery). The Codex session-home bug recorded above is fixed in the same landing (the home becomes a workspace sibling, collected with the workspace) — which for a workspace-less chain bounds Codex project-credential session continuity at the retention window; a later follow-up still runs and degrades honestly through the disclosure path. Claude sessions live in the executor's own home and are unaffected, as are Codex ambient-auth runs (their auth *is* the ambient home, so it is never redirected). | ||
| - **Central host affinity lands as the per-host queue named above**, following Phase B's route-by-capability shape re-keyed by host. Host identity is the identity of the *storage*, not the container — a uuid persisted at `WORKSPACE_ROOT/.agrippa-host-id`, so compose replicas sharing the workspaces volume share it and a redeploy never looks like a dead host. Central runs stamp `runs.workspace_host` first-writer-wins at checkout; follow-ups inherit it; producers route `runtime_id IS NULL AND workspace_host IS NOT NULL` to `run.host.<uuid>`, and each worker polls its own host's queue. Decided 2026-08-16: **initial-run resumes route host-bound too** — same mechanism, and it closes the latent cross-host `waiting_approval`-resume hazard — accepting that a dead host now fails those runs typed via a sweeper rather than bouncing them; **scratch follow-ups stay non-host-routed** this milestone (presence-attach with honest resume degradation, as shipped). The claim-time decline and five-minute grace remain as the deploy-skew fallback. A dead pin still fails `workspace_lost` and is never re-routed — now mechanically, via a dead-host sweep on the heartbeat's host advertisement. |

Document the rejected-resume handoff — The engine intentionally stops the rejected resume invocation, and the daemon completes that dispatch without step.completed or step.failed. This is an intentional handoff, but it violates the documented terminal-event contract. Document this exception and add a remote integration test.

Clean up orphaned staging files. The stale-workspace sweep skips regular files, so it does not delete .agrippa-host-id or treat it as a workspace key. A crash before rm(tmp) can still leave .agrippa-host-id.<uuid> permanently. Add bounded cleanup for stale staging files without deleting .agrippa-host-id.

Wire the publication CAS contract before merge.
apps/worker/src/deps/scm.ts does not pass expectedTip, always returns status: "pushed", and does not map TipConflictError to publish_conflict. Wire these cases before shipping the ADR-0019 flow.

🌐 Web query:
Bun test runner it.skipIf conditional skip API
💡 Result:
The Bun test runner provides the test.skipIf and describe.skipIf methods to conditionally skip tests or entire test suites based on a boolean condition [1][2]. Usage The skipIf modifier accepts a boolean expression. If the expression evaluates to true, the test or describe block will be skipped [3][1]. import { test, describe } from "bun:test"; // Skips the test if the condition is true test.skipIf(process.platform === "win32")("only runs on non-Windows", => { // Test code }); // Skips the entire suite if the condition is true describe.skipIf(process.env.SKIP_INTEGRATION_TESTS === "true")("integration tests", => { test("test A", => {}); }); Related Modifiers - test.if(condition): Runs the test only if the condition is true (the logical opposite of skipIf) [1][4]. - test.skip: Unconditionally skips a test [1][5]. - test.todoIf(condition): Marks a test as "todo" (to be written/fixed) if the condition is true [6][7]. These conditional modifiers are available on both individual tests and describe blocks [1][2].

Guard the permission-based failure test against root execution.
When tests run as root, chmod -R a-w does not prevent Git from writing to chainOrigin. The push can succeed, which makes the error assertions fail. Use it.skipIf(process.getuid?.() === 0) or a failure mechanism independent of file permissions. Bun supports it.skipIf.

The first of M3's PRs (m3-plan), reframed as foundations after review round 3: everything here is inert-until-wired or a standalone bug fix, so it merges ahead of the engine/queue wiring — and migration 0033 landing early decouples schema deploy from behavior deploy. The wiring (P2/P3 publish tail + A2/A3 host routing) follows on a separate PR: "M3 — steering completion".
What this delivers
applyApprovedPatchexpected-tip CAS (packages/workspace): parent selection on the chain's last published snapshot,--force-with-leasefrom it, typedTipConflictError(carrying the observed tip) on any divergence — a human push to the branch always wins; a no-op guard (valid only against the tip it claims) so an unchanged steer never mints an empty advance. Real-git tests: create / advance / idempotent retry / no-op / diverged / deleted-branch / racing advances / broken-remote.WORKSPACE_ROOT/.agrippa-host-id(the storage is the host — replicas sharing the volume share it); additiveruns.workspace_host+worker_heartbeats.workspace_host(migration 0033); first-writer-wins stamping at repo checkout with a DB-enforcedruntime_id IS NULLguard; follow-up inserts inherit the pin; heartbeats advertise it. Nothing routes by it yet.removeWorkspace(ADR-0018's recorded bug), and a resume that dies beforethread.started(missing rollout, reproduced on codex-cli 0.147.0) reports the resume rejected so the engine's context-loss disclosure runs instead of amodel_errorretry loop.Review rounds
Three codex rounds, ten findings, all verified against source and fixed (
24a40c5,12322c4,381e6b8): the approved/published conflation in the ADR's tail guard, the pre-start resume failure mapping, a torn-readable host-id create, a no-op guard that skipped tip observation, and an untyped lease loss, among others.Verification
Full gate green at every commit (
bun run check,bun testwith Postgres — 696 pass / 0 fail / 6 declared skips,templates:validate,build); every deterministic new test verified by neutering its behavior and watching it fail.Summary by CodeRabbit
