Phase 2.6.5 W2 — liveness and deadlines (CR-20, CR-21, CR-21b, CR-21c, CR-22, CR-23) - #85
Merged
Conversation
…he engine enforces it Decides CR-20 (the inert agent-node `timeout_ms`) and CR-23 (a never-settling executor leaves the run without a terminal) together, because they are one mechanism at one place: `#dispatch` is where the engine hands control to code it does not own, and both an authored per-node bound and a post-abort cleanup window are deadlines on that hand-off. Amends ADR-0036, whose Consequences claim that a zombie run is "structurally impossible" — false of the executor seam it defines. §3 makes the executor half true; §6 names the half that stays conditional on the store seam rather than restoring an unconditional claim that would be false again. Two review rounds were folded before Accept, and four of the findings broke claims in the first draft: - The grace window was specified as exceeding the slowest durable write. It does not — `database-schema.md` documents a ~25 s worst case for one `persistEvent`. Terminal durability was never this ADR's to bound (ADR-0078 owns it), so §3 now bounds the EXECUTOR wait and says so explicitly. - `#onRunTimeout` awaits its diagnostic persist before aborting, so a hung store means the grace never arms. §3 inverts the order. - "A monotonic per-run generation" is not implementable under `max_parallel`. §5 specifies `activeDispatchByVertex` with per-vertex replacement. - Racing `execute()` alone leaves a node hung in `save_to` or the money barrier, and `retryable: false` does not stop a per-attempt bound multiplying by `retry.max`. §1 races the dispatch; §2 makes `timeout_ms` absolute per node.

… what nothing tested CR-21 shipped with CR-14 in PR #83: ADR-0082's front matter says it "Decides CR-14 and CR-21", the execution-order graph scheduled them together, and the decision register already recorded its decision as made. Only the heading was stale — a fifth instance of the drift exit criterion 7 exists to catch. Closing it by reading the code found two real gaps rather than none: - **The content-committed DEADLINE case had no test.** Every deadline test timed out PRE-content, and the nearest committed test drives a provider that THROWS after a delta — which lands in the stream loop's catch, not in the `step.kind === 'timeout'` branch. Two lines, one pinned. - **Nothing executed the engine-side port forwarding.** The deadline is host-wired and guarded by a source-grep over the host files, but `#chainCapabilities` (session) and `chainCapabilities()` (runner) are conditional spreads no test ever ran. Measured: deleting the `setTimer` key leaves 1333 of core's 1334 tests green AND both host grep guards green, while every surface silently reverts to unbounded — strictly larger than the hole the grep was written to close. Both paths now have their own behavioural test, because the two express "both or neither" differently. Both mutation-verified. One mutation was wrong on the first attempt and is recorded at the test: deleting the `state` argument is not the isolating mutation — it is a required parameter, so the call throws and four tests redden for the wrong reason. Passing `{ ...state, committed: false }` reddens exactly one. Also adds CR-21c (a single `pollMediaJob` call is unbounded, so ADR-0045's 30-min job deadline can be outlived — found in the same review) and corrects CR-21b's premise: `MediaGenRequest.signal` already exists and is already passed, so no seam amendment is needed. Phase counts move to 15 of 48. current.md also disambiguates the two `W2`s. Refs: ADR-0082, ADR-0085 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…n inside the anti-hollow test The review found a defect in the very mechanism Step 1 shipped, plus five doc contradictions the same commit created. Every finding was re-measured before it was acted on. **The third deadline port was untested, and my own assertion hid it.** Step 1 asserted the armed duration equalled 120_000 and called it "forwarded intact" — but that is DEFAULT_ATTEMPT_TIMEOUT_MS, exactly what FallbackChain falls back to when `attemptTimeoutMs` is ABSENT. The assertion passed whether or not the port was forwarded. Measured: deleting both `attemptTimeoutMs` forwarding lines left the whole core suite green. Both tests now supply a non-default 45_000 and assert it arrives, so the third port is break-verified too — and it reddens by assertion in milliseconds, not by a 5 s timeout. That is a hollow assertion (discipline rule 3) committed inside the test written to catch hollow wiring. It is recorded at the test rather than quietly fixed. **ADR-0082 §12 is EIGHTEEN acceptance items, not sixteen, and item 18 had no implementation.** It asks for the per-chunk verifier cost to be "measured on a representative token stream, not asserted", and its Consequences add "the claim should be evidence". `stream-grammar.perf.test.ts` supplies it — 0.316 µs/chunk over a 2001-chunk turn, logged — shaped after the repo's `sandbox.perf.test.ts` precedent. An Accepted ADR carrying an unimplemented acceptance item is the "reads as shipped" failure this phase exists to remove. **Five doc contradictions, four of them created by Step 1 itself:** - CR-23's heading still said "decision open" and demanded "plus executor quarantine" while the register row it edited said "made" and ADR-0085 §7 DECLINES quarantine — a reader would have built the refused thing. - "W2 is four open items, not five" applied only the subtraction: one item closed and one added cancel, so it is still five. - current.md said "47 items" seven lines above "15 of 48"; CLAUDE.md and AGENTS.md still said "14 of 47". - The "1333 of 1334" measurement was a mid-work snapshot that reproduces on no committed tree. Restated reproducibly, and the absolute count dropped — it rots on the next added test. - CR-21c claimed "the same file" as CR-21b (it is a different file) and named no site; both layers are now named, with the note that bounding either bounds the wait. Also: CR-20 now records that "a classified timeout" had no referent until ADR-0085 §2 (no `node_timeout` exists in the closed taxonomy), and the test doubles now THROW from `generate` per file convention rather than hanging — a hang there would have been indistinguishable from the documented forwarding red.

The test-honesty lens confirmed all three mutation claims reproduce and found one improvement worth taking: the two forwarding tests reddened by timing out, which is honest but blunt. The ADR-0074 precedent they cited is fairly described — its comment in engine.ts says a hang IS the defect stated exactly — but that case has no assertable proxy and these do. `armed` is already collected, so draining bounded microtasks before awaiting the turn turns a 5008 ms timeout into a 3 ms `expected 0 to be greater than 0`. The gain is not only speed. A bare timeout cannot distinguish "the port was not forwarded" from "the turn deadlocked for an unrelated reason"; the assertion can, and names which. Measured after the change: both mutations redden in 3 ms with that message; the suite is otherwise green. Refs: ADR-0082, ADR-0085 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…e production takes The completeness lens found what the two forwarding tests could not: `agent-turn.ts` REBUILDS its `ChainCapabilities` when `preEgress` is defined, and the deadline ports survive that rebuild only by an object spread. Measured: dropping `newAbortController`/`setTimer` inside that rebuild left all 1335 core tests green. And the branches are split the wrong way round for the tests — `session-host.ts` wires `preEgress` unconditionally, so every real CLI chat turn takes the rebuild branch, while both new tests set no `preEgress` and no `budget:` block and therefore took the pass-through branch. The tests proved the ports leave the producers on a path production never walks. Both forwarding tests now run over both branches (the session test gains a `preEgress` variant, the workflow test a budgeted twin). Break-verified: the same mutation now reddens exactly two tests, in ~4 ms, by assertion. Also folded, each measured first: - ADR-0082 §12.13 requires timer cleanup proven "including success", and at chain level every existing assertion followed a failure. Leaking the scope on the stream success exit left 107/107 green. A test now covers both `stream` and `generate`. - That test's first break-verify of the `generate` arm was a NO-OP and is recorded as one: guarding the `finally` with `record.outcome === 'failed'` changed nothing, because the attempt-record factory DEFAULTS `outcome` to `'failed'`. The mutation applied textually and was inert semantically — which is precisely what discipline rule 2 means by "verify the mutation actually applied". - The Batch 2 history said PR #83 closed nine items while the closing register now lists ten; `CR-21` is added to both with the date it was recognised. - `CR-21c`'s register row claimed its decision was "made" while no bound VALUE exists anywhere. The shape is made; the value is now held OPEN the way `CR-31`/`CR-32` hold theirs, with a derivation from ADR-0045's existing `media_job_poll_max_ms` recorded so the maintainer answers yes/no rather than a blank page. pnpm run ci exit 0 (core 1337, llm 771, mcp 68, cli 2525). Refs: ADR-0082, ADR-0085 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…proposal was wrong The decision the register listed as "made" had no value behind it. It has one now, settled with the maintainer before Step 4 writes any code (discipline rule 1): a new `pollCallTimeoutMs: 30_000` in `MEDIA_JOB_POLL_DEFAULTS`, with every call additionally clamped to `min(bound, deadlineAt − now)`. Measuring it inverted the reasoning. This document first proposed deriving the bound from `media_job_poll_max_ms`, on the argument that a poll outliving the maximum interval between polls is no longer polling. Two things came out of checking: - `pollMaxMs` is an INTERVAL, not a duration. The number it yields is fine; the derivation locks together two quantities that may legitimately diverge, so a later change to the polling cadence would silently move a liveness bound. - The instinct to keep the bound tight is backwards here. One failed poll settles the whole job — `#settleMediaJobFailed`, retryable `provider_unavailable` — and a parked media node does not re-enter the node-retry wrapper, so the automatic re-submit is deferred, not shipped. Too tight converts one slow status check into a dead, paid, thirty-minute job; too loose only makes the run wait longer before failing. The defect is unboundedness; tightness is lost money. `LIST_MODELS_TIMEOUT_MS` (15 s) was weighed and declined: the closest precedent by shape, the wrong one by stake — a failed listModels degrades to the static catalog. The clamp is what makes the item's title true. `deadlineAt` is only consulted at the top of the tick, so bounding the call alone still lets a job outlive its own deadline by up to one call.

… claiming its own follow-up was filed Four confirmed findings, zero refuted, zero regressions. Two are defects in ADR-0085 itself, which is the part worth recording. **ADR-0085 §7 asserted, in the present tense, that the quarantine trigger was "Recorded in deferred-tasks.md" — while its own §9 listed that same recording as a still-pending landing obligation, and the file had never been touched.** Zero matches for `0085`, `quarantine` or `CR-23`; its banner still read 2026-07-29. An Accepted, append-only, canonical ADR making a claim that reads as shipped when it is not — the exact failure class this phase exists to remove, inside the document written to remove it. Fixed by DOING the recording rather than softening the sentence: a "Phase 2.6.5 W2 residuals" section now carries §7's quarantine trigger and §6's store-liveness follow-up, each with the reasoning for why it is accepted rather than closed. **ADR-0036 still carried "a zombie / never-terminating run is structurally impossible" with no pointer to the ADR that corrects it.** ADR-0085 §9 deferred that note to "land with the implementation" — but every sibling amendment (0074, 0078, 0079, 0083) added its reciprocal note at acceptance, and deferring it leaves ADR-0036 silently wrong for anyone following CLAUDE.md's own numerical reading order. The note lands now, and says which half of the claim stays conditional. Also folded: - The "exactly two reds" measurement was stale in two places. Adding the branch variants doubled it to four and I did not revisit the adjacent claim — in the same file a3f4765 edited. Re-measured: four reds, 1333 pass. Both sites corrected. - `onAuthError` is forwarded by both producers and exercised by nothing above the chain (deleting both lines leaves 1337/1337 green). Filed as a residual, NOT as a CR-21-class defect, and the distinction is stated: the deadline ports were HIGH because production hosts DO set them, so real values were being dropped. No host sets `onAuthError` at all, so nothing is defeated today — it is a trap for whoever wires it next. The audit lens independently reproduced every claim in the three prior commits by mutation, including that the perf test's `seen` guard catches a count-changing mutation and misses a content-corrupting one — recorded as a limitation rather than left to imply correctness coverage it does not have. pnpm run ci exit 0.

…0085 §9)
`openDeadline` began in `@relavium/llm` for the provider attempt. ADR-0085 needs the
identical primitive in `@relavium/core` for the node deadline and the post-abort grace
window — and `@relavium/llm` exports neither the symbol from its `index.ts` nor a
subpath that could reach it, so the choice was to widen the LLM package's public
surface for a mechanism that is not about LLMs, or to move it to the package both
already depend on.
It moves, with `AbortControllerLike`, which `@relavium/llm` and `@relavium/core` had
each declared as a byte-identical copy. Two structural duplicates of one type are
compatible right up to the day one of them gains a field.
What stayed: `DEFAULT_ATTEMPT_TIMEOUT_MS`. The deadline MECHANISM is generic; that
NUMBER is a statement about provider latency and belongs with the seam that knows
about providers.
Two decisions inside the move, recorded because neither is mechanical:
- `SetAttemptTimer` became `SetDeadlineTimer`. "Attempt" names a provider call, and a
node deadline is not one. The engine's own `SetTimer` — which carries ADR-0036's
third `TimerKind` argument — stays assignable to it, so a host wires one port and
both consumers accept it.
- The tests did NOT move. `@relavium/shared` sets `types: []` so a stray
`process`/`Buffer` is a compile error — that boundary is the guard, not a lint rule
— and the two load-bearing cases need `process.on('unhandledRejection')` to prove
the abandoned step is discarded HANDLED. Relaxing it for file adjacency would trade
an architectural guarantee for a filename, and splitting one coherent suite across
packages reads worse than keeping it whole.
Proven rather than assumed: breaking the caller-abort latch in the new
`@relavium/shared` home reddens three tests in `@relavium/llm`, so the re-export is
the path under test, not a stale copy. Exactly one `AbortControllerLike` interface and
one `openDeadline` implementation remain in the tree.

…looking number
The Step 2 review found what a green CI structurally could not, and it refutes the
call I made in that commit.
Keeping the deadline suite in `@relavium/llm` after moving the code to
`@relavium/shared` looked like the careful choice: shared sets `types: []`, and two
cases need `process.on('unhandledRejection')`. Measured, it cost a guarantee.
`@relavium/llm` resolves shared from `dist/`, so V8 attributed **0%** to
`packages/shared/src/deadline.ts` despite 13 tests exercising it — while the 90% floor
that used to guard that code (`vitest.config.ts` covers `packages/llm/src/**`, never
`packages/shared/src/**`) was left holding a 35-line re-export shell scoring a perfect
100. The enforced branch number went UP, 96.96 → 97.11, as the guarantee went away.
The sharpest part: the pre-move coverage report's one uncovered line was
`onCallerAbort`'s waiter wake. That signal sat inside an enforced floor, the move
erased it, and the branch turned out to be held by nothing.
Three branches were untested — each deleted with the entire 782-test llm suite green:
- **the mid-race caller abort** (`onCallerAbort`'s waiter wake). The suite covered a
caller aborting BEFORE a race and BETWEEN races, never one landing while `race()` is
already awaiting — the common shape, a user hitting Ctrl-C mid-stream. It readmits
the exact defect this file's header records a review catching: the race stays pending
to the absolute deadline, so a cancel looks ignored for 120 s.
- **the cooperative abort on that path**, asymmetric with the deadline path, which IS
covered. Without it the caller still gets liveness from the latch, so the run LOOKS
fine while the provider is never told to stop and a real fetch keeps billing.
- **`dispose()`'s idempotence guard**. The old assertion could not fail: the harness
disarm is `pending.delete(fire)`, and `Set.delete` on an absent element is already a
no-op, so it proved `Set.delete` idempotent rather than `dispose`. Now asserted on a
disarm COUNT.
A fourth test I wrote for `waiters.delete` was HOLLOW — deleting the line left it
green, because a leaked waiter's promise is already settled, so waking it changes
nothing observable. Removed and replaced with the gap, the reason it is not reachable
through this surface, and the mutation that would close it. A test-only accessor was
refused on the precedent this phase set for `#turnCount` in CR-02.
Tests split 11/2: the eleven needing no platform type moved to
`packages/shared/src/deadline.test.ts`; the two needing `process` stayed and say why.
`deadline.ts` now measures 100% lines / 96.66% branches, above its pre-move 93.33%.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>…t hold Three findings from the two Step 2 review lenses I had not read when I folded the first one, each measured before acting. **`packages/shared`'s `types: []` was not guarding anything.** Its `tsconfig.json` comment read "this, not ESLint globals, is the guard" — and appending `process.env` to `deadline.ts` typechecked CLEAN under it. The program includes `*.test.ts`, whose `vitest` import transitively pulls in `@types/node` and defeats `types: []` for every file in it. `packages/llm/tsconfig.seam.json` and `packages/core/tsconfig.purity.json` both carry an explicit test exclusion for exactly this hazard, with the reason written down; `shared` was the only one of the three without it, while claiming the guarantee. It gets `tsconfig.purity.json`, wired into `typecheck` beside the full-coverage config. Break-verified: the same probe now fails the purity config and still passes the coverage config, which is the correct split. This also retires the reasoning behind Step 2's original "tests stay in llm" call. It was already refuted on coverage grounds; it turns out the architectural blocker it cited was not in force either. The two `process`-dependent cases now stay for a guard that actually bites. **A third `AbortControllerLike` existed and had already drifted.** The commit that converged two byte-identical copies verified "exactly one `export interface`" in the tree — a check structurally blind to an inline return-type literal. `apps/cli/src/process/sleep.ts`'s `hostAbortController` declared the shape inline and had lost the `readonly` on `signal`. It is the host wiring point for the very primitive that moved, so it was the copy most likely to break. Now annotated with the shared type. **`hostAttemptTimer` kept the retired vocabulary** at the only place a host implements `SetDeadlineTimer` — renamed. The rename exists because "attempt" names a provider call and a node deadline is not one; leaving it at the implementation would have handed the next reader the old word at the moment ADR-0085 wires the node deadline. Also recorded, not fixed: `SetDeadlineTimer` cannot carry `TimerKind`, so `openDeadline` structurally cannot arm a `liveness` timer. Correct today — both hosts default to `work` and ADR-0085's two timers are `work` — but it is a one-way door, now written where the assignability claim is made. pnpm run ci exit 0; pnpm coverage exit 0.

…ed to inherit (CR-22) Both halves were broken, and neither needed a new durable field — "persist absolute deadlines" turned out to be half already done. **The gate half.** `human_gate:paused` has carried `expiresAt` and `timeoutAction` since PR #22, and its schema says in as many words that they ride there "so a Phase-2 crash-resume can re-arm the timer from the persisted log". The gap sat one layer up: `reconstructCheckpointState`'s fold dropped both, so `CheckpointPendingGate` could not carry them and `#seedFromCheckpoint` had nothing to re-arm from. A multi-gate run, or a crash while parked, rehydrated its remaining gates with no timer at all — their deadlines simply stopped existing. The old deferral reasoned that "the gate this resume TARGETS has its decision applied immediately", which is true of the target gate and silent about every other one. **The run half.** `#armRunTimeout` armed the full `timeout_ms` on every call, both resume paths included, so a run crashed and resumed ten times got ten times its authored budget. ADR-0028 makes it a bound on TOTAL wall-clock. The fix needed nothing persisted: `#seedFromCheckpoint` already restores `#startEpochMs` from the checkpoint's `startedAtMs`, and both resume sites arm after that seeding. A past deadline arms at zero on both halves rather than resolving inline, so it travels the one `#onGateTimeout` / `#onRunTimeout` path — a past-deadline resume and a live expiry produce identical events in identical order. What the tests found is worth recording: - The gate half had a test pinning the OPPOSITE behaviour. Rewritten, not deleted, keeping the reasoning it replaces — the way CR-14's superseded test was handled. - The run half had NO test: reverting it left all 1338 core tests green. - Both are pinned on the ARMED DURATION (15 000 of a 60 000 cap; 250 of a 1 000 gate). A test asserting only "a timer was armed" would pass for the exact bug it exists to catch. Each is break-verified against a full-duration mutation. And a process note: the first attempt at that break-verify was a NO-OP because prettier had wrapped the expression across four lines and a single-line replace did not match. Second time this round; the mutation is now applied line-precisely and confirmed to bite before the red is trusted. Closes the long-standing deferred item "Re-arm a still-pending gate's timeout on cross-process rehydration", whose note correctly predicted no backfill would be needed. pnpm run ci exit 0; pnpm coverage exit 0.

…1b, CR-21c) Neither needed a seam amendment. `MediaGenRequest.signal` already existed and `ctx.signal` was already passed; `pollMediaJob` already took a signal. In both cases the only gap was that nothing raced the await — and a signal is a request rather than a guarantee (ADR-0082 §5). **CR-21b** — the `generateMedia` submission. ADR-0082 §10 named this call and declined to absorb it: not a poll, so ADR-0045's job deadline misses it; not a chain attempt, so §6's per-attempt deadline misses it too. It got its OWN bound rather than the chain's. Borrowing `DEFAULT_ATTEMPT_TIMEOUT_MS` was the first attempt and the packaging refused it — ADR-0085 §9 keeps that constant inside `@relavium/llm` deliberately, so reaching for it would have widened that package's public surface to let the ENGINE bound a media call, and would have coupled two budgets answering different questions. `MEDIA_GEN_SUBMIT_TIMEOUT_MS` is equal today and independent by construction. **CR-21c** — one `pollMediaJob` call. The loop's `deadlineAt` is consulted at the TOP of each tick, twenty-five lines above the await, so a provider whose poll never settles stranded the run past its own thirty-minute deadline indefinitely. Bounded at `pollCallTimeoutMs` (30 s) clamped to the job's remaining deadline — the clamp is what stops a job outliving its deadline by up to one call. It lands at the ENGINE layer, not the executor arm beneath it, because only the engine holds `deadlineAt`. **A third timer role fell out of it.** Arming these as `work` broke six existing media tests at once: a drive-to-quiescence loop fires every armed `work` timer to advance the run, so a deadline swept into that set trips the instant it is armed and every media test becomes a timeout test. The run is not waiting ON a deadline — it waits on the CALL, and the timer matters only if the call does not come back. `TimerKind` gains `'deadline'`; `fireTimers()` no longer sweeps it and `fireDeadlines()` trips one deliberately. The CLI host `unref`s it, because the in-flight call's own socket is already holding the loop open. ADR-0085's node deadline and grace window are the same role and inherit it. Two things the tests found, both worth keeping: - **The CR-21c test was hollow on its first pass**, caught by its own break-verify. The harness binds the agent timer port to the same `'deadline'` kind, so the first backstop to arm is CR-21b's on the SUBMISSION; the test observed that one, fired it, and passed with the poll bound removed entirely. It now waits for `media_job:submitted` first. - **The m2 harness wired neither deadline port into its agent deps** while `build-engine.ts` wires both, so CR-21b's bound armed nothing there — the same "the port is forwarded and the test takes the branch that does not use it" shape CR-21's own close-out had to fix twice. pnpm run ci exit 0; pnpm coverage exit 0. Phase 16 → 18 of 48; W2 down to CR-20 and CR-23, which ADR-0085 decides together. Refs: ADR-0036, ADR-0045, ADR-0082, ADR-0085 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The Step 3 review found a regression the CR-22 tests structurally could not see, and
verifying it took a real macrotask to reproduce.
Rehydration arms a deadline for every pending gate — the point of the item — but that
includes the gate this resume TARGETS, and a past-deadline gate arms at zero.
`beginResume` then awaits `#resolveContextOrFail` and `#effectResumeGateOrFail`
BEFORE `resume()` claims the gate, while `#onGateTimeout` guards only on
`#settled || !#pendingGates.has(gateId)` — both still permissive in that window.
Measured with `timeout_action: approve` and a caller supplying `rejected`: the durable
log recorded `human_gate:resumed{decision: 'approved', decidedBy: 'timeout'}`. A
human's explicit refusal, rewritten as an approval attributed to a timer. It also
contradicts execution-model.md's own contract — "a decision that arrives first
disarms the timer" — and on a cross-process resume the decision definitionally
arrived first: it was handed to `resumeFromCheckpoint` before the timer existed.
The targeted gate's timer is now disarmed synchronously, before any await. Every
other gate keeps its re-armed deadline, which is what CR-22 exists to restore.
Reachability, stated precisely: unreachable on today's CLI, where better-sqlite3 is
synchronous and both awaits settle in microtasks so a `setTimeout(fn, 0)` lands after
them. Live the moment any of those `Promise`-typed seams does real I/O — which is
exactly what Phase-2's Postgres `EffectResumePort` is. The regression test injects
that boundary rather than a contrived one, and it is why the first version of the test
passed against the unfixed code.
**A second, bounded exposure closed with it.** `expiresAt` is an instant compared
against a different machine's clock, so a resuming process running BEHIND the one that
parked the gate computed MORE remaining time than the author granted — an hour of skew
re-armed a 1 000 ms gate at 3 601 000 ms. `Math.max(0, …)` only guarded the other
direction. The authored `timeout_ms` now clamps from above; it was already on
`human_gate:paused` and the fold dropped it, exactly like its two siblings.
Both fixes break-verified. pnpm run ci exit 0; pnpm coverage exit 0.

The user asked whether the round had finished; it had not — I had read one of six results. The other two lenses held the sharper findings. **The motivating case had no test.** All three CR-22 tests resume a run's ONLY gate — which `resume()` disarms two lines later, i.e. precisely the "target gate" case the old deferral was right to say did not matter. What the item actually fixes is a gate that SURVIVES the resume, and nothing pinned it. There is now a two-gate test that resumes one and asserts the other still holds a deadline at its own remaining time, and is still armed after the resume re-parks. **Three assertions were inert.** `armedWork` is exactly one element, so every `not.toContain(...)` was implied by the `toContain(...)` above it and no mutation could make it the failing line. Worse, the justification I wrote for `toContain` — "the resume also arms unrelated work timers" — is measurably false: this resume arms exactly one. The superseded test's exact count (`toBe(0)`) had also proved "no other work timer is armed anywhere", and `toContain` silently dropped that. All three are now `toEqual([...])`, which restores it at zero cost. **The run-side `Math.max(0, …)` clamp had no test** — removing it left all 1339 tests green, and it is invisible to coverage because `Math.max` is a call, not a branch, so v8 reports the line covered. The gate half had a past-deadline test from the start; this adds its missing twin, break-verified (`expected [ -59000 ] to include +0`). **The checkpoint carry-forward arms are unreachable from this engine, and my comment said otherwise.** `#settlePaused` always emits `budget:paused` BEFORE the companion `human_gate:paused`, so the deadline-bearing event is always the later one — the comment claiming they "arrive in either order" is not what the emitter does. They are kept, because this is a pure fold over durable rows that outlive the code that wrote them, and now pinned directly at the fold in both orders rather than left as the only uncovered lines in the file. **Two sibling roadmap docs still tracked this exact defect as open** — the run half in phase-2.5.5 (issue #75, same function, same mechanism) and the gate half in phase-2.6 under 2.6.K, in a table that already had the annotation convention for an early close. Closing an item in one document and leaving it open in two others is the propagation gap this phase exists to correct. pnpm run ci exit 0; pnpm coverage exit 0.

…, CR-23) ADR-0085's whole decision, implemented as one step because §1 says it is one problem: `#dispatch` is where the engine hands control to code it does not own, and both an authored per-node bound and a post-abort cleanup window are deadlines on that hand-off. **CR-20 — the authored bound now does something.** `AgentNodeSchema` accepted `timeout_ms`, node-types.md and workflow-yaml-spec.md both advertise it, and `AgentPlanConfig` carries the whole node so it arrived at dispatch — with no consumer. It bounds the WHOLE dispatch, not just `execute()`: `#applySaveTo` runs on its return, `#joinMoneyDurability` after `#runAttempt` returns, and the retry backoff sits between attempts, so a node hung in any of those was still `running` with its deadline satisfied. And it is ABSOLUTE across the node, not per attempt — a per-attempt reading multiplies, since two ordinary retryable failures then a timeout spend roughly three times the authored bound and `retryable: false` only stops the timed-out attempt being retried. Classified `run_timeout` / `retryable: false`, which is not a new decision: `#failGateOnTimeout` already settles the human gate's authored `timeout_ms` exactly so. **CR-23 — one grace window, armed off the abort signal itself.** Registered in the constructor, unconditionally. Both words are the decision: there are eleven `#abort.abort()` sites and a per-site arm is a per-site omission waiting to happen — the sibling ADR-0074 §3 listener solved this class once and says so — and that sibling sits inside `plan.budget !== undefined`, so it never protects an unbudgeted run. Every vertex still running when it elapses gets a `node:failed` first, so the durable log has no `node:started` without a partner. The message is fixed text because `cancelled` alone would read as "the user cancelled this node" when the truth is that the engine stopped waiting. **The ordering fix that makes the rescue reachable.** `#onRunTimeout` awaited its durable `run:timeout` write BEFORE aborting — so a store that never settles meant the abort never fired and the grace window never armed. The rescue path was defeated by the very stall it exists to rescue. The event is a record of a decision already taken; it is now written second. **The fence** is per-vertex (`activeDispatchByVertex`), not a run-wide counter — which would make one parallel sibling stale another's live work. Applied at the two points that were unguarded: the `cost:updated` fold, and `save_to`, which is the only one that writes bytes to the user's filesystem, on the executor's return, before `#onOutcome`'s `#settled` latch is ever reached. Three tests, each break-verified line-precisely after a first mutation landed on the wrong one of two identical lines: the never-settling executor produces exactly one terminal; the authored 4000 ms is the value that arrives (not a default — the hollow shape CR-21's close-out had to fix twice); and a node with no `timeout_ms` arms nothing, the negative control without which the first test passes for an engine that bounds everything.

…nref'd a deadline a review had already measured
The Step 4 round found two real defects I shipped, and one of them is PR83-03's
defect reintroduced one call site over.
**CR-21b opened its deadline with no caller signal.** `openGenerativeDeadline` called
`openDeadline(ms, newController, setTimer)` — no fourth argument — while both siblings
pass one (`FallbackChain` its `req.signal`, `#openPollDeadline` its `#abort.signal`).
The scope's merged signal REPLACES `ctx.signal` on the request, so the merge was the
only thing still connecting a run cancel to the adapter, and there was no merge.
Three failures from one omission: a well-behaved adapter never saw the cancel; `race()`
had no caller waker, so the node waited out the full 120 s after a Ctrl-C — which is
exactly what `deadline.ts`'s own docblock records a prior review measuring, "120
seconds of a cancel that looks ignored"; and `classify()` could never return `'caller'`,
making the `cancelled` arm dead code that reported a cancel as a RETRYABLE
`provider_unavailable` a node-retry budget can spend on a second paid submission.
Nothing caught it because every generative cancel test wires no timer port, so all of
them take the `deadline === undefined` arm — the branch CR-21b did not change. The same
"the port is forwarded and the test takes the branch that does not use it" shape the
commit itself named, reproduced in the same commit.
**The CLI host unref'd the `deadline` kind, against a measurement already in the tree.**
I reasoned that the in-flight call's own socket holds the loop open.
`hostDeadlineTimer`'s docblock refutes it with numbers, taken against ADR-0082's own
motivating provider — a `new Promise(() => {})` that holds nothing: the loop drained,
the process exited with a bare code, and the deadline never fired. ADR-0085's node
deadline and grace window face precisely that shape by construction. Only `liveness` is
unref'd again.
**An Accepted ADR was contradicted by the code.** ADR-0085's Consequences say the two
timers it adds are `work`; Step 5 arms them `deadline`. Amended in place with a dated
note (append-only), recording that the third kind did not exist when the ADR was
written and that the distinction is a test-harness one, not a ref-counting one.
Also folded:
- `execution-host.ts`'s `TimerKind` doc claimed CR-21b's bound is the `deadline` kind.
It is not and cannot be: it reaches its timer through `AgentRunnerDeps.setTimer`, a
`SetDeadlineTimer` whose signature carries no kind. The bound is real and tested; it
is simply not tagged.
- `#openPollDeadline` declared `| undefined` for a host that cannot exist — both
`ExecutionHost` members are required — so the branch and its docblock were fiction.
Removed.
- The clamp, which the commit called "what makes the item's title true", had ZERO
coverage: every test ran with ~1 799 997 ms remaining, so the constant always won the
`min` and deleting the clamp left them green. Now pinned, break-verified
(`expected 30000 to be less than 30000`).
- `deadline.ts`'s "one-way door" note was wrong twice: binding the kind at the call site
is the supported shape, not a workaround, and it asserted the ADR's now-amended claim.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>…and what the fence does NOT carry
§5 names five mutation points. Step 5 fenced two. This adds the effect journal's
per-METHOD rule and pins both, including one honest negative result.
**The effect journal, per method.** A blanket "refuse a stale write" would resurrect
PR83-04 exactly: a row stuck `prepared` forever, swept by nothing, reported as
`needs_attention` for an effect that actually completed. So `prepare` is refused — the
effect has not left the process, and an abandoned dispatch must not start new external
work — while `settle` and `discard` are admitted, because refusing a receipt for work
that already left strands the row precisely as PR83-04 did. The refusal REJECTS rather
than resolves, so a caller that ignores it cannot mistake it for a durable claim.
**And what the fence does not carry today, measured rather than assumed.** Removing the
`cost:updated` fence leaves the straggler test green: by the time an abandoned executor
emits, the run has settled and the bus is closed, so `#settled` is what does the work.
`#step` has the only `#dispatch` call site and claims only `pending` vertices, and
`#onGraceElapsed` marks abandoned vertices `failed` rather than returning them to
`pending` — so a vertex cannot be dispatched twice while the first is in flight and the
dispatch-id comparison is DEFENSIVE on today's engine.
It stays, and §5 says why it must be per-vertex if it exists at all: a run-wide
"current generation" would make one parallel sibling's dispatch stale another's live
work. What makes it unreachable is a property of the scheduler — and the scheduler is
exactly what ADR-0085 §7 says a long-lived host will change. The test now says this
outright and names the mutation that would close it, rather than implying coverage the
suite does not have.
The effect-fence test IS break-verified: removing the `prepare` guard reddens it with
`promise resolved "{ outcome: 'proceed' }" instead of rejecting`.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>W1 has one; W2 did not. The criterion is "per item, the code that closes it — verified by reading the code, not by trusting the mark", and W1's own register earned its keep twice: it caught two items marked open that had already shipped, and a later review still found six defects in the code it vouched for. So this one names, per item, the mechanism and the test that would fail if it were reverted — every one of which was confirmed to fail line-precisely, after four separate occasions this wave where a textual mutation applied and was semantically inert. Two things it deliberately does not claim, because measurement said otherwise: - The `cost:updated` and `save_to` fence points are NOT independently proven. Removing the `cost:updated` guard leaves the straggler test green — by then the run has settled and the bus is closed, so `#settled` carries it. The dispatch-id comparison is defensive on today's scheduler, and the register says so rather than letting the table imply coverage. - CR-23's guarantee is bounded exactly as ADR-0085 §6 states: run liveness with respect to the EXECUTOR. A `persistEvent` that never settles still hangs the run. Tracked in deferred-tasks, not fixed. Also corrected two things in the same pass, both the class this wave keeps catching: - The straggler test's NAME still said "the fence refuses…" after its body was rewritten to say `#settled` does the work — a title claiming more than the test. - This register's first draft said "four resume cases" for CR-22. There are seven, and each is now named. I have caught that arithmetic in three review rounds; writing it myself is the reason the register exists.

…e acceptance withdrawn The round read ADR-0085 section by section against the code. Five gaps, each fixed and break-verified; one item that cannot be met and is corrected in the ADR instead. **§1's obligation had never been written where it belongs.** The ADR says it goes in the seam docblock "so an implementor reads it where they implement, not only in an ADR" — and `NodeExecutor.execute` was a bare signature. Only the enforcing half had landed. **§2's "absolute per node" was absolute per DISPATCH.** An approved budget gate returns the vertex to `pending`, `#claimReady` re-claims it, and the node got a second full-length bound — the same shape as CR-22's run cap renewing on every resume, one level down. Now computed from the node's first dispatch. Reverting it left all 110 tests in the file green; there is now a budget-approval re-dispatch test that reddens with `expected 5000 to be less than 5000`. **§2's claim that the deadline covers `save_to` describes a combination the schema forbids.** `timeout_ms` is declared only on the agent and human-gate nodes, `save_to` only on the output node, so no vertex can carry both. The comment asserting it is replaced with the fact. **§5's first fence point was unimplemented, and the obvious predicate was wrong.** `#onOutcome` guarded on `#settled` alone, so a node whose own `timeout_ms` tripped could still report success afterwards while a sibling kept the run alive — a node claiming completion for work the engine already told the user had timed out. Keying the fence on the dispatch token refused every media-job completion instead, because a parked job legitimately settles out of band after `#dispatch` returns. The honest predicate is the vertex's own terminal status. Break-verified: without it, node `a` gets two terminals. **§4's abandoned-node event was hand-rolled** and silently dropped the `correlationId` ADR-0036 calls the single producer-side translation point, the cost snapshot the schema says the engine always populates, and the real attempt number (hard-coded 1, so a node abandoned on attempt 3 logged attempt 1). It goes through `#settleFailed` now. An abandoned node's record is the only one it gets; making it the thinnest in the log is the wrong place to economise. **And §8.9 is WITHDRAWN rather than worked around.** It asked for a terminal even when the `run:timeout` persist never settles. The ordering fix §3 requires is real and landed — the abort fires before the diagnostic write, so the executor is told to stop and the grace window arms. But ADR-0078 serialises every emit behind one delivery tail, so the abandoned nodes' events and the terminal queue behind the hung write. That is exactly the limit §6 already states, so the acceptance item was asking for more than the ADR claims, and the correction belongs to the item. pnpm run ci exit 0; pnpm coverage exit 0.

… had no skew clamp Three findings from the final round's correctness lens, each verified and break-verified. Two are my own inconsistencies. **§5's fence points 2 and 3 did not fence.** Both read `#dispatchIdForVertex.get(vertex.id)` at WRITE time, and `#dispatch` writes the same id into both maps — so while any dispatch of that vertex is active the two sides are equal by construction and the predicate degenerates to `!#settled && has(vertex)`. That is exactly the "second boolean latch" ADR-0085 §5 rejects, in as many words, because it cannot tell dispatch N from N+1 — and the budget-approved re-dispatch produces precisely that. `#fenceEffects` had it right: it captures the id when the context is built. These two now do too. It was not theoretical and it was not covered: a stale `cost:updated` of 999 999 from dispatch N was DELIVERED while N+1 was in flight, and neutralising either guard left the entire core suite green. §8 items 14–16 claim that window is refused. **The run cap's resume re-arm had no upper clamp.** `#elapsedMs()` differences this process's clock against `#startEpochMs`, seeded from ANOTHER process's `run:started`, so a resuming clock running behind yields a negative elapsed and a remaining LARGER than the authored cap — measured at an hour of skew, a 60 000 ms cap re-armed at 3 660 000 ms. The gate half gained this exact clamp from the Step 3 round and the run half, twenty-five lines away, did not. Same exposure, same one-line fix, simply not carried across. **A fenced settle left the grace window armed.** `#settle` reaches its fenced branch and returns before its own `#disarmGraceWindow()`. The cost is concrete: the CLI deliberately does not `unref` a `deadline` timer — a hung executor may hold no socket, so the backstop is the only thing that will unblock the run — and sets `process.exitCode` rather than calling `process.exit`, so a fenced `relavium run` sat idle for the full 10 s after finishing. ADR-0085 §8.12 claims all three settle paths are proven by the armed count; only the normal one was. Three tests, each break-verified. The fenced one lives in `run-lease.test.ts`, where the takeover fixture already is, rather than re-creating it — and it waits for the node to be genuinely in flight first, because cancelling before it starts settles the run normally and never takes the fenced path at all. pnpm run ci exit 0; pnpm coverage exit 0.

…ntradicting themselves The final round's process and product lenses found the two things this phase exists to prevent, in a branch whose whole purpose is preventing them. **A canonical doc still asserted the claim this branch disproves.** `phase-1-engine-and-llm.md`, inside a section marked ✅ Done, read "a zombie / never-terminating run is structurally impossible" — word-for-word what ADR-0036's own 2026-08-27 amendment calls not true. Shipping that sentence in this PR would be indefensible. It now carries a dated correction naming what was and was not met: the three parenthesised acceptance cases hold; the unconditional sentence did not. **Four of ADR-0085 §9's six landing obligations had a ZERO diff.** §9 says in as many words that they "land with the implementation, not after it". They now do: `node-types.md` and `workflow-yaml-spec.md` say what the agent `timeout_ms` does and that it is absolute across attempts and re-dispatches; `sse-event-schema.md` and `error-handling.md` record that `run_timeout` is carried by three distinct causes with `error.nodeId` as the discriminator; `execution-model.md` names all three timeout sites and the grace window. The `execution-model.md` idempotency-key clause is scoped OUT rather than silently skipped — it is ADR-0080's sentence to correct, not this ADR's. **The live-status surfaces contradicted themselves.** The phase doc's status line said "`W2` is in progress" while the same file said COMPLETE and all six items said CLOSED; `current.md` still listed `CR-20`/`CR-23` as open and carried a banner sixteen days stale relative to its own last edit. `current.md` calls itself canonical for live progress, so a reader after this merges would have re-opened closed work. Also: my own W2 closing register repeated ADR-0085 §2's false claim that the node deadline covers `save_to` — the schema forbids the combination, and a register that repeats an error it exists to catch is worse than no register. And the in-place ADR amendment had left an orphaned duplicate of its own trailing clause. pnpm run ci exit 0. Zero broken links.

…instead of waiting The security lens found a governance control that turns into its own bypass, and reproduced it in Node directly. `positiveInt` has no upper bound, so a workflow author may write a thirty-day `human_gate` `timeout_ms`. Node's `setTimeout` emits `TimeoutOverflowWarning` and silently sets the duration to **1 ms** — measured: `setTimeout(fn, 2147483648)` fires on the next tick. With `timeout_action: 'approve'`, a gate an author configured to wait a month auto-approves immediately. That is the control granting exactly what it exists to withhold. It reached every arm site unclamped: the node deadline and the media bounds through `openDeadline`, and the run cap, gate timeout and gate re-arm through the engine's direct `setTimer` calls. Both shipping hosts are bare `setTimeout`. Clamped at the seam — `MAX_TIMER_DELAY_MS` in `@relavium/shared`, applied in `openDeadline` and at the three engine sites — rather than per host, since every host has the same 32-bit ceiling. **Clamped rather than refused at parse**, deliberately: the authored schema is a published contract, so narrowing it would reject workflows that parse today. A run bounded at 24.86 days instead of 30 is a bound the author would recognise; one that fires in 1 ms is not. Break-verified: removing the clamp reddens with `expected [ 2592000000 ] to deeply equal [ 2147483647 ]`.

…d that was false
The final round's test-honesty lens broke every assertion this branch added. Six
mechanisms had no test that could fail, and one thing I had RECORDED as a limitation
turned out not to be one.
**The record was wrong, and that is the worst of these.** The W2 register said the
`cost:updated` fence was defensive — "the bus is closed, so `#settled` carries it". The
bus is not closed to subscribers. A live `handle.subscribe()` observer receives a stale
`cost:updated` of 999 999 after the terminal with the guard removed; the old test only
looked green because its `for await` capture had already stopped. Recording a gap that
was not real is the same failure as missing one that is: it told the next reader to
trust something doing nothing and distrust something doing the work. The test now uses
a subscriber and is break-verified.
Five mechanisms gained their first real test, each break-verified:
- `#fenceEffects`'s LIVE `prepare` pass-through. Mutating `return port.prepare(...)` to
throw left all 1355 tests green — a regression breaking every effectful node's
dispatch would have shipped silently. The test now asserts the live call reaches the
port AND the stale one does not.
- `#onRunTimeout`'s abort-before-write ordering, with a store that hangs on exactly that
write. It asserts what the fix buys and no more — the grace window ARMS — because
ADR-0078's delivery tail means no terminal can follow, which is why §8.9 is withdrawn.
- `GRACE_WINDOW_MS`'s value. The manual timer discards `ms`, so every prior test would
have passed for any number; 77 777 and 0 both left the suite green. Pinned with a
literal, deliberately: importing the module-private constant would compare it to
itself.
Two hazards fixed rather than only noted:
- `#fenceEffects` spread the port (`{...port}`), which copies own properties only — a
class-based `EffectDispatchPort` would arrive with `settle`/`discard` undefined. Both
shipping implementations are object literals, so it was latent. It delegates now. I
then hit the identical bug myself writing this commit's store double, which is the
best argument for the fix.
- `MEDIA_JOB_POLL_DEFAULTS` lost its docblock when `MEDIA_GEN_SUBMIT_TIMEOUT_MS` was
inserted above it — the description sat on the wrong constant for a commit.
Also: `attempt-timer.test.ts` kept the retired vocabulary in its basename after the
`hostDeadlineTimer` rename, and three docs said "the eleven cases" of a file that now
holds fourteen. The counts are removed rather than re-pinned — an absolute test count in
prose rots with the next test.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>…grace on cancel The final round's product lens found a user-visible behaviour difference nobody decided, and reproduced it: a node carrying `timeout_ms` was abandoned on the next tick after a cancel, while a node without one got ADR-0085 §3's full 10 s window. `openDeadline`'s `race()` returns the same `'deadline'` outcome for a caller abort as for an elapsed bound, and `#dispatchBounded` settled on both. So the asymmetry fell out of the mere PRESENCE of an authored bound — a value that says nothing about cancellation — and it negated §3's own justification for that window, "would abandon well-behaved work that was seconds from returning", for precisely the nodes an author had thought about. `classify()` already separates the two causes. Only the node's own expiry settles there; a caller abort returns and lets the grace window govern, identically to an unbounded node, so `#dispatchLoop` keeps running and may still settle cooperatively — which is what the window is for. The test asserts the EQUALITY of the two shapes first and the policy second: whatever the grace policy is, an authored `timeout_ms` must not silently change it. Writing it also took three attempts, each worth recording: `deadlineCount()` cannot be the trigger, because the bounded shape has already armed its own node deadline of the same kind; cancelling in a loop throws once the run settles; and waiting for any `node:started` waits for the INPUT node, so the cancel lands while nothing is running and the run closes at once without ever reaching the path under test.

Subtracting it lands at ~12, which matches the pre-branch estimate — so this branch is what crossed the line. The seeding loop now reads as the list of restorations it is, and the re-arm reads as one decision with its own name. No behaviour change: the same clamps, the same arm-at-zero for a past deadline, the same reasoning, moved intact.

`CLAUDE.md` and `AGENTS.md` described the phase as `W0` + `W1` only. `W2` closed on 2026-08-27 and they are the first thing an agent in this repo reads, so leaving them a wave behind is the same drift the phase's rule 5 exists to stop — three review rounds on this branch each found an instance of it. Both now name the wave and what it actually changed, in one sentence apiece: the authored agent `timeout_ms` bounds the node, every media call is bounded, a resume no longer renews a deadline it inherited, and an executor that ignores its signal can no longer leave a run without a terminal.

…ide its own grace window Four review comments and five SonarCloud findings, each verified against the code before acting. All nine were valid. **The load-bearing one: the fence slot was released too early.** On a caller abort `#dispatchBounded` returns while `#dispatchLoop` is still running — deliberately, so the grace window governs. But `#dispatch`'s `finally` then deleted the vertex's `#activeDispatchByVertex` entry, un-fencing a node that was still legitimately live. An executor that honoured its signal and settled cooperatively INSIDE the window had its `cost:updated` fold refused and, worse, its `save_to` write skipped — the window exists to let exactly that work land. The release is now deferred on that path; `#onGraceElapsed` clears the map when it stops waiting, and `#isLive`'s `!#settled` half still refuses anything after the terminal. Nothing covered it; a test does now. **The node-timeout path reported the wrong attempt.** It passed `firstAttempt` where the grace path passes `#lastAttemptByVertex`, so a node that timed out on attempt 3 logged attempt 1. **ADR-0085 acceptance item 8 was unqualified** while item 9 carried the qualification they both need: the grace window bounds the wait for the EXECUTOR, not the store, so a blocked `persistEvent` or delivery tail means no terminal follows. Item 9's amendment had also left a dangling "The original text follows." joined onto an orphaned fragment. SonarCloud, all three in code this branch added: - `applyGateEvent` at 24, from three nested ternaries that were the same `??` written three ways. One named `carryGateDeadline` merge replaces them, and it carries the reason the branch is unreachable-but-kept where the merge is, instead of as a comment above a spread. - `executeGenerativeMedia` at 22 — the `CR-21b` race is lifted into `submitGenerativeMedia`, so the function's budget and egress bookkeeping reads as one story again. pnpm run ci exit 0; pnpm coverage exit 0. Core 1362. Refs: ADR-0036, ADR-0078, ADR-0085 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
… the entrance Five blockers from the PR review, each reproduced against the code first. They share one root cause: an ownership decision made at a point in time, guarding work that spans awaits. **B1 — the node deadline belonged to a dispatch call, not to the node.** `#dispatch` opened it and its `finally` disposed it unconditionally — but `paused` and `media_job` are outcomes, not node terminals. A node authored `timeout_ms: 1000` that parked on a media job lost its bound entirely and ran under ADR-0045's thirty-minute JOB deadline instead, failing `provider_unavailable`/retryable where ADR-0085 §2 promises `run_timeout`/fatal. Same for a human-gate park and a budget-approval park. The deadline is now owned by the run, keyed by vertex, armed once and disarmed only at the node's terminal — `#settleCompleted`, `#settleFailed`, skip-propagation, gate resolution, and the run-wide sweep. That also makes "absolute per node" true across parks, not just across attempts and re-dispatches. **B3 — the timeout boundary was not an ownership cutoff.** The old path awaited `#onOutcome → #settleFailed → #emitDurable` and released the dispatch id only in a later `finally`, so for the whole duration of that durable write the timed-out executor's cost folds and `effects.prepare()` calls still passed `#isLive`. `#onNodeDeadline` drops ownership synchronously, before the first await. **B2 — the grace cutoff was not atomic.** `#step` awaits its `node:started` persist and then calls `#dispatch` without re-reading the run's state, so a node claimed before the window elapsed could still START after it. A `#noNewDispatch` latch is set synchronously when the window fires, and `#step` re-reads it after that await. **B4 and B5 — two fences guarded the entrance to an async call and nothing at its exit.** The effect fence checked `#isLive`, then awaited the journal write, then handed back a `proceed` that `registry.ts` dispatches on with no further check: the grace window and the terminal can both land inside that await, and the losing side is an external effect performed for a terminated run. `save_to` had the identical shape, with a file on the user's disk as the losing side — the fence guarded entry while `#performSaveTo` resolved a template, de-inlined media and read the store before calling `mediaWrite`. Both now re-check immediately before the irreversible step. Tests: the media-park survival is pinned by watching the node deadline's DISARM rather than the terminal, because `fireDeadlines()` fires whatever is armed at that instant and asserting on the terminal would have been asserting on an interleaving. The budget-approval test now pins the stronger property it earned — armed once for the node, not re-armed per dispatch. pnpm run ci exit 0; pnpm coverage exit 0. Core 1363.

…long deadlines fired days early Two of the review's three High findings, both verified against the code first. **H7 — credential resolution was a hole in cancellation.** All three seam paths awaited `keyFor` and then called the provider without re-reading the caller's signal. A cancel landing inside that await was invisible: the request went out, and only the deadline opened AFTERWARDS latched the aborted caller, so `race()` reported `cancelled` for traffic that had already happened — and could already have been charged. Every path re-checks now: both `FallbackChain` arms and the media poll. This is the same shape as the two fences in the previous commit. A check that guards the entrance to an async call guards nothing at its exit. **H8 — clamping a long timer was a silent semantic change.** The previous commit fixed Node inverting a >2³¹−1 ms delay into a 1 ms fire, by clamping to 24.86 days. That is better and still wrong: a thirty-day authored `timeout_ms` then fired 5.1 days early, and a governance gate with `timeout_action: 'approve'` would auto-approve days before anyone expected it with nothing saying so. `armLongTimer` chains hops of at most the host ceiling and carries the remainder, so the total is the bound the author wrote. Its disarm cancels whichever hop is armed, so it stays one-shot from the caller's side. Used by `openDeadline` and by all four engine arm sites — run cap, gate arm, gate re-arm, node deadline. Rejecting long timeouts at parse was the alternative and stays declined: the authored schema is `positiveInt` with no upper bound and is a published contract, so narrowing it would refuse workflows that parse today. Both break-verified. The cancel test drives a `keyFor` the test releases by hand — the window is only observable if you can hold it open — and asserts `providerCalls === 0` on each arm. The chain test walks hop by hop and asserts they sum to the authored thirty days, not merely that the first one is within the ceiling. pnpm run ci exit 0; pnpm coverage exit 0. Refs: ADR-0028, ADR-0082, ADR-0085 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…not the ledger High 6 of the Request-Changes round. The per-vertex dispatch fence (ADR-0085 §5) refused the whole `cost:updated` event from a stale closure, including the fold into `#cumulativeCostMicrocents`. That counter is what `TurnMoneyPort.record` stamps as the row's `cumulativeCostMicrocents`, so a genuinely billed attempt produced `cumulative 0 < cost 999999` — which `refineCostAttemptSettled` rejects at a producer gate running in `#bus.next`, OUTSIDE `#emitDurable`'s try. It threw where the design assumes it cannot, and the durable money row was lost. `#nodeEmit(event, deliver = true)` now folds unconditionally and fences only the emit: a charge the provider took is recorded either way (ADR-0045 §5); what the fence stops is re-announcing a total to subscribers after the terminal published one. The regression test asserts BOTH halves — no delivery, and a run total that includes the stale charge — and was break-verified against the old behaviour. Refs: ADR-0085, ADR-0045 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…the run Medium 9 of the Request-Changes round. `#armNodeDeadline` runs OUTSIDE `#dispatch`'s `try`, so a host whose `setTimer` throws — the third `'deadline'` kind ADR-0085 §4 introduced — rejects the promise at `void this.#dispatch(...)`. Un-caught that was two defects at once: an `unhandledRejection`, and a run with no terminal at all (the node stayed `running`, so `#handleIdle` saw work in flight forever and no `run:failed` was ever published). The call site now routes any dispatch fault through `#settleFailed` — the same settle every other node failure takes — with `#failNodeInternal` as a last-ditch fallback if the settle itself faults on the same broken host. Measured while building this: the in-memory flag ALONE still hung, because it emits no `node:failed`, so the graph never published the node's terminal. The regression test drains a run to its terminal under a one-shot faulting host and asserts no `unhandledRejection` fired; it hangs to a 5 s vitest timeout against the pre-fix code (break-verified). The fault is one-shot deliberately: `'deadline'` is also the abort path's own kind, so a permanently faulting host breaks the settle under test and proves nothing.

…0085's claims
Medium 10 and Medium 11 of the Request-Changes round.
`openDeadline` and `DEFAULT_ATTEMPT_TIMEOUT_MS` were re-exported by
`attempt-deadline.ts`, but nothing re-exported that module from `index.ts` and
`package.json` exposes only `.` and `./adapters` — so no consumer of
`@relavium/llm` could reach either symbol. ADR-0085 §9's re-export obligation was
satisfied on paper only, which is the same unreachability it was written to end.
The guard test reads the module NAMESPACE: a named import is resolved by the
bundler and proves nothing about what the entry point publishes.
Three ADR-0085 claims are corrected with dated notes (append-only — the original
text stays):
- §5 item 1 ("the token subsumes the boolean") — it does not. The token was tried
at `#onOutcome` and refused every async media-job completion, because a
`media_job` PARKS and settles out of band from the poll timer. The shipped
predicate is the vertex's own terminal node status.
- §8 item 5's `save_to` half is unreachable by construction: the schema puts
`save_to` on `output` only and `timeout_ms` on `agent`/`human_gate` only, so no
authored node can carry both. The claim was written from the engine's call graph
without checking what the parser admits. The money-barrier half stands.
- §8 items 15 and 18 said a stale `cost:updated` moves neither the counter nor a
subscriber. Fencing the fold loses a durable ledger row — the reason recorded in
the preceding commit. The rule is: the fold is unconditional, delivery is fenced.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>… docblocks Low 12 and Low 13 of the Request-Changes round. `current.md` contradicted itself: the prose said Wave 0's CI-truth PR was "in flight (PR #80)" when W0 merged as PR #82 and W1 as PR #83, and the Mermaid node read "47 CR items · W0+W1 closed (14)" against the phase doc's authoritative "20 of 48". Both now match the phase document, which is the canonical home. `CLAUDE.md` and `AGENTS.md` were already correct. Three docblocks documented something other than the declaration they sat on: - `constants.ts` carried a duplicate `MEDIA_JOB_POLL_DEFAULTS` description stranded above `MEDIA_GEN_SUBMIT_TIMEOUT_MS`'s own. Deleted, keeping the one sentence it alone carried (the `[defaults].*` overrides validate but are not yet read) by folding it into the surviving block. - The same file claimed `DEFAULT_ATTEMPT_TIMEOUT_MS` "is not exported from that package's index" — true when written, false since the preceding commit. The argument does not depend on it: §9's line is about which package OWNS the number, not about reachability. - `engine.ts` had the retry-loop description on `#dispatch`, which now only brackets the loop, while `#dispatchLoop` — where those semantics live — had no docblock at all. Split: `#dispatch` documents the fence slot and the node bound (the two things that must outlive an individual dispatch), `#dispatchLoop` the retry budget. Refs: ADR-0085 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…round The register's "Two things this register does not claim" heading had stood alone for several commits: its first paragraph was rewritten into the correction that follows it, and its second drifted to the end of the section. Both are restored. A heading with nothing under it reads as a claim that was made and quietly dropped — the same failure the register itself calls out. It also named two methods that no longer exist (`#openNodeDeadline`, `#dispatchBounded`), so a reader checking the mark against the code would have found nothing. Corrected to the shipped names, and `CR-23`'s row now names the `.catch` that closes the terminal-less-run path. Records the PR #85 Request-Changes round and its one root cause: the five blockers were one mistake made five times — an ownership decision taken at a point in time, guarding work that spans an await. ADR-0085 §2 listed `save_to` among what the node bound covers. Corrected in place with a dated note: the schema puts `save_to` on `output` only and `timeout_ms` on `agent`/`human_gate` only. The clause is harmless (it widens the bound to something unreachable) but a reader who trusts it looks for a test that cannot exist. Refs: ADR-0085 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Low 14 of the PR #85 review: 31 of 34 subjects exceed the ~72-char guidance and 20 use a comma-separated multi-scope where `commit-style.md` asks for a primary scope with the rest named in the body. The maintainer's call was to leave it. Recorded rather than silently dropped, with the trade that justifies it: rewriting the history changes every SHA on an open PR and un-anchors the inline comments the fourteen findings were attached to — a worse outcome for a branch whose value is its reviewability. The remedy is forward-looking: W3 writes them correctly from its first commit. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Align acceptance items 15 and 18 with the unconditional cost fold.
These items still say that a stale cost update changes neither the cumulative fold nor delivery. The correction below says the fold is unconditional and only subscriber delivery is fenced. The cumulative value feeds TurnMoneyPort.record, so fencing the fold can recreate the cumulative < cost failure described in docs/roadmap/phases/phase-2.6.5-core-reliability-remediation.md. Make item 15 require fold admission with delivery suppression, and make item 18 require stale ledger-write and fold admission.

Preserve the absolute deadline when a timer hop fires late.
Line 90 subtracts the planned hop duration, not the elapsed duration. If a 30-day timer fires five days late after process suspension, Line 91 arms the remaining 5.1 days and expires about five days after the authored deadline.
Store an absolute target and recompute the remaining delay from an injected platform-neutral clock before every hop. Do not use an ambient platform clock.

…r wrote Raised as a PR #85 inline comment and verified against the code. Both of `#applySaveTo`'s dispatch-liveness fence paths returned the unchanged `completed` outcome — the entry check, and `#performSaveTo`'s `undefined` (its success signal) at the last check before the write. That told `#onOutcome` the write had happened, defeating the fence they were part of: `#isLive` goes false the instant `#onGraceElapsed` clears the dispatch map, which is BEFORE `#settled` is set and before the grace loop reaches that vertex. Both paths now return a typed `cancelled` failure. `cancelled` and `retryable: false` deliberately — cancel-wins precedence means `#settleFailed` leaves an already-recorded `#failure` alone, so this classifies the NODE without overwriting the run's real cause. The message is path-free and byte-free (I3). Measured rather than assumed, and it differs from the review's prediction. Under `InMemoryRunStore` the defect is invisible: the store resolves synchronously, so the grace loop settles the node first and `#onOutcome`'s status guard closes the window by accident. The regression test therefore drives an ASYNC store — the seam's stated reality (1.R SQLite, Phase-2 cloud) — under which the abandoned node ends with NO node terminal at all, the omission ADR-0085 §4 forbids. The review predicted a persisted `node:completed`; a different microtask alignment gives either. Both are the same defect. The test also needed its cancel gated on the executor actually running, not on `node:started`: `#step` emits that event and then re-reads the `#noNewDispatch` latch, so a cancel landing in between leaves the node started-but-never- dispatched and reproduces nothing. Break-verified line-precisely. Refs: ADR-0085, ADR-0044 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

F1 of the PR #85 round, verified reachable. ADR-0085 §8.12's grace-window leak was one instance of a general asymmetry, and closing that instance left the general case open: `#settle` sweeps every timer the run armed, but its fenced branch returns to `#settleFenced` BEFORE reaching that sweep, and `#settleFenced` disarmed the grace window, gate timers, media timers and run timeout — not the node deadlines. The node deadline is precisely the one that survives. §2 makes it run-owned and disarmed only at the node's TERMINAL, so a node in flight when the lease is lost (a slow provider call, a media park, a gate park) is still holding one by design. Same cost as §8.12's and larger: the CLI does not `unref` a `deadline` timer and sets `process.exitCode` rather than calling `process.exit`, so a fenced `relavium run` sat idle for the node's full authored `timeout_ms` where the grace leak cost ten seconds. The regression test arms a node deadline WITHOUT cancelling first, unlike §8.12's, so `deadlineCount()` is unambiguous — a cancel would arm a second `deadline` timer and the assertion could pass on the grace disarm alone. Also drops the `[...map.keys()]` spread at all three sweep sites (SonarCloud, two Lows). Deleting the entry a `for...of map.keys()` loop is standing on skips nothing — the delete tombstones in place and the iterator has already advanced past it. Measured, and the note records it so the defensive-copy reflex does not re-add it. For an entry added mid-loop the live form is the safer one anyway: it disarms the late arrival instead of leaking it past the terminal.

…minal F2 of the PR #85 round. `#onGraceElapsed` is fired from a timer as `void this.#onGraceElapsed()`, and it could throw in two places, neither guarded. `#settleFailed` is not the total path its callers assume. `#emitDurable` absorbs store faults, but `#bus.next` — which stamps the sequence number and Zod-parses the candidate — runs OUTSIDE that try, and so does `host.ids.newId()` in the draft. A throw aborted the whole abandonment loop: every remaining abandoned node lost its `node:failed` (the omission ADR-0085 §4 forbids), the `#failure` fallback was skipped, and `#schedule()` never ran. Measured: the run hangs to a 5 s vitest timeout — terminal-less, produced by the backstop whose one job is to guarantee a terminal. The node-deadline sweep runs BEFORE that loop, so a host whose disarm throws rejects the method outside every try it contains. That half is an `unhandledRejection`, fatal under Node's default `--unhandled-rejections=throw`. Two guards, each with its own test because neither covers the other: a per-vertex catch inside the loop (continuing is safe — `#settleFailed` sets `status` and `#failure` synchronously before it emits, so the vertex is already marked and the run already has a cause), and a `.catch` at the call site, mirroring the rule the `#dispatch` call site follows. A break-verify caught a false comment in the second test. It selected the node deadline as "the first `'deadline'` armed", but `node:started` is emitted before `#dispatch` arms the bound, so a cancel landing in that gap arms the 10 s grace window first — and the test then faulted the grace disarm, which `#onGraceElapsed` never invokes. It now selects by the authored delay, and reddens line-precisely. Also declines two findings from the same round, with the reason recorded in docs: the roadmap diagram is not contradictory (it states item CLOSURE while line 40 states MERGE status), so the diagram now says so in words rather than changing a count that five other locations already agree with.

…f a correction
An adversarial pass on this round's own ADR notes found two things the notes got
wrong, and one place the standard was not followed.
The 2026-08-28 note on §5 item 1 justified rejecting the dispatch token with
"`#dispatch`'s `finally` releases the vertex's slot on return, but a `media_job`
PARKS". That release was narrowed to a node TERMINAL hours later in this same
branch, so the stated mechanism is refuted by the code beside it. Three reasons
survive and none is about slot release: `#onOutcome` is re-entered out of band
from three sites that hold no dispatch id at all; a cross-process resume
rehydrates a parked job into a `RunExecution` whose `#activeDispatchByVertex`
never held that vertex (`#dispatch` is its only writer); and after the grace
clears the map an abandoned node's `cancelled` outcome must still land, because
§4 requires the terminal. The engine comment is corrected in place and the ADR
gets a second appended note — the first is not rewritten, since a correction
whose own reason was wrong is itself part of the record.
§5's admission rule ("a write is admitted only when the run has not settled AND
the dispatch id matches") reads as universal and is not: it holds for the four
points that write from inside a dispatch, not for `#onOutcome`. It now says so,
and is left as written — narrowing it silently would hide that the ADR once
claimed it of all five.
All nine 2026-08-28 corrections are re-cast as the dated `> **Amended**`
blockquotes documentation-style.md §7 prescribes, instead of inline bold. That
form is what makes an in-place edit honest history rather than a quiet rewrite,
and it also fixes three notes that had run to 380-810 characters on one line.
Refs: ADR-0085
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>…timer rewrite Two records the PR #85 round earned indirectly. ADR-0085 §2 never said what happens to a node bound across a cross-process resume, and the answer is not the one CR-22 established for its siblings. A node `running` at the crash is absent from the checkpoint, so resume seeds it `pending` and re-runs it; `#nodeDeadlineStartMs` is in-memory and never checkpointed, so the resumed dispatch arms the FULL authored `timeout_ms` — where the run cap and the gate deadline re-arm at their REMAINING time precisely so a resume cannot renew them. The asymmetry is deliberate and now says so: the run cap bounds wall-clock that genuinely continued, and a gate's `expiresAt` is a durable instant, but the node's prior attempt produced nothing that survives — charging its elapsed time against the fresh attempt would bill the author for work that was thrown away, and a node that crashed at 90% of its bound could never complete afterwards. The run cap still bounds the total. If the other reading is wanted it needs a checkpoint field, so it is tracked rather than silently changed. The `armLongTimer` absolute-deadline rewrite is declined, and the two reasons the first pass gave for declining it were both wrong. It is NOT blocked by the ADR append-only rule — documentation-style.md §7 permits an in-place dated amendment — and multi-hop is NOT unreachable by construction: `attemptTimeoutMs` is caller-supplied with only a finite-and-positive check, and the shared test suite already exercises a thirty-day chain. The true reason is narrower and sufficient: no shipped surface passes a large value, the spec's largest documented value is single-hop, and a late hop drifts LATE — the safe direction for a backstop. The cheaper fix if it ever matters is a ceiling at validation, not a clock threaded through a contract ADR-0085 §9 deliberately kept narrow.

…verstated PR #85 merged 2026-08-28. The five places that carry the interlude's status now say merged rather than closed-on-a-branch, and `current.md`'s live-status block gains its Batch 3 entry — including the Request-changes round the wave went through, since the register's value is that it records what was declined as well as what was fixed. CLAUDE.md claimed W2 delivered "resume no longer renews a deadline it inherited". That is true of the run cap and a pending gate and NOT of the node bound, which a cross-process resume does renew — deliberately, for the reason ADR-0085 §2 now records. Corrected rather than left to be read as a guarantee the engine does not make. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Closes Phase 2.6.5's
W2— Liveness and deadlines, all six items, behind a newADR-0085.
The wave's thesis in one line: the engine could promise a run always ends, and not keep it.
NodeExecutor.executereturns an arbitrary promise,cancelonly fires a signal, and the terminal waitsfor the running-node count to reach zero — so an executor that ignored its signal left a run with no
terminal, forever, and the same gate defeated ADR-0028's run cap. ADR-0036's Consequences called that
"structurally impossible". It was not.
What each item was
CR-20timeout_msparsed and did nothing — advertised in two canonical references, with no consumerCR-21CR-14in PR #83; only its heading was stale. Closed by reading the code, plus the tests nothing hadCR-21bgenerateMedia()submission awaited unboundedCR-21cpollMediaJobcall unbounded, so a job outlived its own 30-minute deadline indefinitelyCR-22CR-23What it added
not per cancel site, because there are eleven of those and a per-site arm is a per-site omission.
node:startedwithout a partner.TimerKind,deadline— a backstop over work already in flight is neitherwork(the run isnot parked on it) nor
liveness(firing it does advance the run).openDeadlinemoved to@relavium/shared, so four bounds share one primitive.Review
Seven rounds: one per step, then a final end-to-end pass over the whole branch (14 agents, seven
independent lenses — correctness, security, test-honesty, performance, code quality, product fit, process
integrity — each adversarially refuted). Every finding was measured before it was fixed, and every fix
break-verified by line-precise mutation.
They found real defects in my own work, repeatedly. Worth naming, because the pattern is the point:
§5fence did not fence — both guards compared a value against itself, so a stalecost:updatedof 999 999 was delivered while its successor dispatch was live.
CR-21breintroducedPR83-03's defect one call site over: the deadline opened with no caller signal, soa cancel reached neither the adapter nor the race and was reported as a retryable
provider_unavailable.timeout_msabove 2³¹−1 inverts: Node clamps it to 1 ms, so a thirty-day gate withtimeout_action: 'approve'auto-approved on the next tick. A governance control granting what it existsto withhold.
timeout_mssilently removed the node's grace on cancel — an asymmetry nobody decided.cost:updatedfence wasdefensive "because the bus is closed". It is not closed to subscribers. Recording a gap that is not real
is the same failure as missing one that is.
Two acceptance items are withdrawn rather than worked around, both against ADR-0085 §6:
§8.9cannotbe met because ADR-0078 serialises every emit behind one delivery tail, and the guarantee is run liveness
with respect to the executor — a
RunStorethat never settles still hangs the run. That residual istracked, not hidden.
