This ADR's stated worry — that per-call placement would have to be re-proven for every dispatch path — is answered by there being one dispatch sink with two producers, not a path per producer. + ## Context [ADR-0076](0076-durable-per-attempt-realized-cost-ledger.md) decided that a settled provider attempt's realized diff --git a/docs/decisions/0078-ordered-durable-append-and-the-terminal-outbox.md b/docs/decisions/0078-ordered-durable-append-and-the-terminal-outbox.md new file mode 100644 index 00000000..9e847119 --- /dev/null +++ b/docs/decisions/0078-ordered-durable-append-and-the-terminal-outbox.md @@ -0,0 +1,114 @@ +# ADR-0078: The durable event log is an ordered append, and a terminal that cannot be made durable says so (amends ADR-0036 and ADR-0042 §4; establishes the shared durable-write seam) + +- **Status**: Accepted +- **Date**: 2026-08-11 +- **Related**: [ADR-0036](0036-run-loop-substrate-event-bus-and-execution-host.md) (the event bus, the `ExecutionHost` seam and exactly-one-terminal — amended here) · [ADR-0005](0005-sqlite-drizzle-local-postgres-cloud.md) (one schema, two dialects) · [ADR-0073](0073-history-db-migration-lock.md) (the store's cross-process posture) · [ADR-0074](0074-durable-conservative-budget-commitments.md) · [ADR-0075](0075-fail-closed-resume-on-an-unreadable-event-log.md) · [ADR-0076](0076-durable-per-attempt-realized-cost-ledger.md) · [ADR-0077](0077-realized-cost-ledger-uses-the-conservative-commitment-barrier.md) (the money barriers whose correctness rests on `#emitDurable`'s totality) · [ADR-0042](0042-engine-media-storage-substrate-mediastore-deinline-retention.md) §3-4 (the media reclaim this reorders). [ADR-0049](0049-cli-machine-output-contract.md) (the CLI exit-code taxonomy §5 extends). The store's concurrency and transaction policy has one canonical home, [database-schema.md](../reference/shared-core/database-schema.md) §"Concurrency & transaction behavior"; the event contract is [sse-event-schema.md](../reference/contracts/sse-event-schema.md). **Decides** `CR-10` and `CR-92` of [phase 2.6.5](../roadmap/phases/phase-2.6.5-core-reliability-remediation.md); the implementation is staged behind it. It does not close them — that phase records, at length, that an accepted ADR with no implementation is a decision which reads as shipped, and that Wave 1's completion claim was wrong twice for exactly this shape. + +## Context + +Every durability guarantee this project has shipped assumes the durable event log is an **ordered prefix** of what the run produced: the checkpoint fold, resume, reconciliation, and ADR-0075's strict read all read it that way. Nothing establishes it. + +`#emitDurable` assigns a sequence number at one authoritative point and then **starts each event's persistence independently**, serializing only delivery — *"Persists stay concurrent; only delivery is serialized."* (`engine.ts`). The store commits each event in its own `IMMEDIATE` transaction, and the only database-level constraint is `UNIQUE(run_id, seq)`, which bars a duplicate and says nothing about order or holes. + +**How reachable that is, stated precisely, because an imprecise version of this sentence would make this ADR wrong on its first pass.** On the CLI's own store the happy path is not affected: `better-sqlite3`'s `db.transaction(...)` is fully synchronous and runs before the first real `await`, so the commit lands inside the same synchronous block that assigned the sequence — measured, commit order was `1,2` every time. Out-of-order commit becomes reachable through exactly two doors: a `SQLITE_BUSY` backoff that yields the event loop mid-retry — which the store's own comments and `database-schema.md` already describe, and which cross-process contention on a shared `history.db` makes expected — or a genuinely asynchronous store, which the `Promise`-typed port exists for and which Phase 2's cloud store will be. So the defect today is that **nothing but timing prevents it**, and the seam is explicitly designed to admit an implementation where timing does not. + +The damage is not a mis-ordered read. Readers already sort. The damage is the **missing row**: a `node:completed` that never lands leaves its vertex absent from the reconstructed state, so a resumed engine seeds it `pending` and re-runs it — which is how this item opens the duplicate-effect door that `CR-12` owns. + +The terminal has a second, distinct problem. `#emitDurable` is deliberately **total for store faults**: a failed write is absorbed and the event is delivered anyway, because exactly-one-terminal is sacred and a store fault must never escape as an unhandled rejection out of the fire-and-forget loop. For a non-terminal event the run is additionally failed, so progress is never reported that the log lacks. **For a terminal there is no such compensation.** A caller receives `run:completed` with outputs while the durable record says the run failed — or says nothing at all — and `reconcile()` may later write a *different* terminal for the same run. The media reclaim compounds it: the run's media references are released *before* the terminal write is known to have landed. + +Three constraints shape what may be done about it: + +1. **ADR-0077's money barriers rest on that totality.** Both `money-durability.ts` and `engine.ts` state in terms that the `CommitmentDurabilityError` catch is "deliberately unreachable" on the run path *because* `#emitDurable` absorbs and resolves. Both money events are non-terminal. +2. **`reconcile()` is a second write path.** It bypasses `#emitDurable` entirely and calls the store directly. Every property established at the choke point has to be re-established there, or it holds for one of the two writers. +3. **The store that must hold a terminal outbox is the store that just failed.** A row in the same `history.db` is unavailable for most of the fault class the outbox exists to survive. + +Finally, three sibling W1 items — `CR-11`'s fencing token and `CR-12`'s effect journal — need to change the *same* `persistEvent` signature. Landing them separately would break one exported port three times across four packages and every test double. + +## Decision + +**We will serialize each run's durable appends into one ordered tail, guard the append at the store with a compare-and-append, hold a terminal the store could not accept in a host-owned outbox outside the store, and report a run whose terminal is not known to be durable as `uncertain` rather than as success.** The `persistEvent` port takes one extensible context object so the two sibling items extend it rather than re-break it. + +### 1. One ordered append tail per run + +`#emitDurable` moves the `persistEvent` call **inside** the existing per-run serialized region, so event `N+1`'s write is not started until `N`'s has settled. Delivery ordering is unchanged; today's region already resolves in sequence order, and this makes the *ask* order match it. + +**The mechanism is a one-line move, and no second tail is introduced.** Today the region reads *start the persist → `await prior` → deliver*, so `#deliveryTail` serializes only delivery. It becomes *`await prior` → persist → deliver*: the same single tail then serializes the ask, the write and the delivery, in that order, for one run. This matters beyond tidiness — it is what makes §2's `expectedLastSequenceNumber` well-defined at the call site, because the previous event's write is known to have settled before this one is composed. A separate `#persistTail` alongside the delivery tail is rejected: two chains over one ordering property is how they drift, and the totality argument in §6 would then have to be re-derived for each. + +No new await is introduced and the SEQUENTIAL path is unchanged — a caller already awaited a region containing `await prior`. For a CONCURRENT emitter it is not free, and saying otherwise would contradict this ADR's own first Negative: its resolve time goes from `max(persist, prior)` to `prior + persist`. That is the throughput cost, stated once here and once there rather than twice with opposite signs. + +Two placements are stated separately because they are twenty lines apart in the same method and a reviewer skimming "move the media call" will conflate them: + +- **The media de-inline stays OUTSIDE the region.** It is an awaited host round-trip (`MediaStore.put` / `fetchMedia`) with no bound this engine controls. Inside the region an unbounded host stall would block every later durable write for the run, including the terminal. +- **The media reclaim moves AFTER a successful terminal persist.** A terminal whose write failed must not have already released the run's media references (ADR-0042 §3-4). + +Considered instead: a global append tail across all runs (rejected — one slow run would stall every other, and the ordering property is per-run by definition); and leaving the engine unordered and relying solely on §2's store guard (rejected — the guard would then *reject* legitimate concurrent asks, converting a latent ordering hazard into a live failure). + +### 2. Compare-and-append at the store, through one context object + +`persistEvent` becomes `persistEvent(event, ctx: DurableWriteContext)`. `DurableWriteContext` carries `expectedLastSequenceNumber` now; `CR-11` adds its fencing token and `CR-12` its journal correlation to the same object. + +The store evaluates the guard with a `SELECT max(seq)` **inside the existing `IMMEDIATE` transaction**, through the `tx` handle rather than the outer `db` — the reason is already recorded in `run-history-store.ts`: with a pooled Postgres driver the outer handle is a different client, so its statements would run outside the transaction and survive a rollback. A violation is a typed rejection, not a silent skip. + +Considered instead: a denormalized `runs.last_event_seq` column (rejected — it needs a migration and a snapshot regeneration for a value `max(seq)` already yields, and it introduces a second source of truth that can drift from the rows); and a parameter list rather than a context object (rejected — it is the signature that gets broken three times). + +`InMemoryRunStore` enforces the identical guard. A reference implementation that accepts what the real store rejects makes every `packages/core` test prove nothing. + +### 3. `reconcile()` is a first-class second write path + +It passes its own expected last sequence, and its repair append becomes **conditional on no terminal being present**. Without that condition §4's outbox retry and reconciliation can both append a terminal, breaking ADR-0036's exactly-one-terminal invariant. Fixing this is nearly free today — no shipping surface calls `reconcile()` — and becomes a data-loss bug the moment one does. + +### 4. The terminal outbox lives outside the store, behind a host port + +A terminal whose durable write fails is written to a **`TerminalOutbox` port on `ExecutionHost`**, retried under the same identity, and drained on the next start. + +This is the one place this ADR spends real complexity, and it is deliberate. The alternatives were weighed: + +- **An outbox row in `history.db`** (rejected): unavailable for most of the fault class it exists to survive — a full disk, a corrupt database, an exhausted busy-retry all fail the outbox write for the same reason they failed the terminal write. +- **No outbox at all**, relying on `reconcile()` to repair (rejected): reconciliation writes `run:failed{internal}` for a run that actually *completed*. The divergence is relabelled, not closed, and the outputs are gone. The phase's exit criterion permits this cheap option; the maintainer ruled for real fault isolation instead, and the reasoning is that a lost `run:completed` payload is unrecoverable while an extra host port is merely more code. + +The port is **required**, not optional. The optional-port precedent on `ExecutionHost` (`mediaStore?`, `fetchMedia?`) is absent-tolerant because a text-only host legitimately has no media. There is no legitimate host with no terminal durability, so optional here would mean a host that forgets the port silently has no guarantee — a fail-open default inside a fail-closed item, invisible at every call site. + +**The outbox is drained BEFORE reconciliation, and that order is load-bearing.** §3's "no terminal present" condition makes the two writers safe within one process; across processes it does not. A crashed process leaves its terminal in the outbox, and if the next process reconciles first it sees a run with no durable terminal, concludes it needs repair, and writes `run:failed{internal}` for a run that completed — the exact divergence this section exists to close, reintroduced by ordering. Draining first means a terminal a prior process could not commit is recovered before any process decides the run is broken. + +**A drained entry is reconciled against the log, not replayed blindly.** An entry whose run already carries a durable terminal is dropped, not appended — the write may have committed and only its acknowledgement been lost, and appending would break exactly-one-terminal in the other direction. + +**An entry whose run is never started again stays until it is swept.** That is correct, not a leak: the run finished, only its durable record is missing, and the payload is the only surviving copy. It does mean the outbox is unbounded in principle, so the host implementation carries a retention bound — the entry is dropped once its run's terminal is durable, and a host may age out entries under the same retention policy that governs run history. The engine does not own that policy; it owns only the write-and-drain contract. + +### 5. Durability is reported, not assumed + +`RunHandle` gains a `durability: 'durable' | 'uncertain'` disposition alongside its terminal. `uncertain` means the terminal was delivered in-process but its durable write did not land and the outbox has not yet confirmed it. + +The marker is **handle-level, never on the `RunEvent`**. The store persists the delivered event verbatim as the lossless canonical record, so a live-only field either lands on disk — self-contradictory, since the row existing *is* the durability — or forces the delivered and persisted forms to diverge. + +This vocabulary is minted **once, here**. `CR-11` reuses it for a fenced-out run and `CR-14` for a grammar violation on already-forwarded content, rather than each inventing a parallel shape. The CLI maps `uncertain` to its own exit code; the taxonomy extension is recorded in [ADR-0049](0049-cli-machine-output-contract.md)'s canonical home. + +### 6. Totality is preserved for non-terminal events + +Every disposition change above is scoped to the **terminal** arm. Non-terminal writes keep absorbing store faults into the run's failure state and resolving, exactly as ADR-0077's B1/B2/B3 correctness argument requires — and both money events are non-terminal. The two comments that state that argument are re-derived in the same change, because a reviewer reading only `#emitDurable` will not find them. + +### 7. What "durable" means here + +**Process-crash durability, not power-loss durability.** The client sets `synchronous = NORMAL` under WAL, so a committed transaction can be lost on an OS crash or power loss. Every sentence in this ADR of the form "`N` is durable before `N+1` is written" is scoped accordingly. Flipping to `FULL` is a measurable throughput change on the run's highest-volume write path and deserves its own decision with its own measurement — not a side effect of an ordering ADR. + +### 8. What this ADR does NOT change + +Stated explicitly, because the next reader will otherwise try to simplify it away: **ADR-0074's sum-vs-last-wins rule and the `Math.max` checkpoint fold survive completely unchanged.** Those are driven by sequence-*assignment* order among concurrent emitters, not by commit order. An ordered append tail cannot give two concurrent `fan_out` branches a canonical order — nothing can. Likewise the realized-cost ledger's telescoping `run_costs` delta stays: its cause is that `MoneyDurability` stamps the cumulative captured at `record()` time, which is correct and is not an ordering artefact. + +**That last point carries a doc obligation, not just a caution.** The comment above the telescoping delta in `run-history-store.ts` currently justifies it by out-of-order COMMIT — the thing §1 removes — so the moment the tail lands, the money write's own stated reason is contradicted by the code beside it, and the next reader deletes the telescoping. CR-10's implementation rewrites that comment to the real reason (a stamp-time capture, unaffected by ordering), alongside §6's two re-derivations. + +## Consequences + +### Positive + +- The durable log becomes an ordered append in fact, not by assumption, and the guard survives a store implementation whose commits are genuinely concurrent. +- A caller can no longer be told a run completed while the durable record disagrees — the single failure the durable-truth oracle was built to detect. +- One port change instead of three: `CR-11` and `CR-12` extend `DurableWriteContext` rather than re-breaking `persistEvent`. +- `reconcile()` stops being a write path with none of the choke point's properties. + +### Negative + +- **Throughput.** Serializing the appends removes write concurrency within a run. Mitigated by the media de-inline staying outside the region — the only unbounded await on the path — and by the fact that the store's transaction is synchronous today, so the concurrency being removed is largely notional. +- **A new required host port**, which every host and every test double must supply. Mitigated by an in-memory reference implementation shipped with `createInMemoryHost`, following the `newAbortController` precedent. +- **`uncertain` is a new outcome surfaces must handle**, and a CLI exit code is a user-visible contract change. Mitigated by minting it once for three items rather than three times, and by recording it in ADR-0049's canonical home. +- **The outbox can itself fail.** A host whose outbox write fails has no further recourse; the run reports `uncertain` and stops there. That is the honest floor, and it is stated rather than papered over. +- **`CR-10`'s headline property is still not provable from the log alone.** Streamed events consume sequence numbers and are never persisted, so a healthy log legitimately reads `[0,1,2,3,5,10,…]` and a streamed event's absence is indistinguishable from a lost one. Proving "the committed set is a prefix of the asked set" needs a store harness that records what it was *asked* to persist. That harness is built before the implementation, exported from `packages/core` the same way `checkDurableTruth` is, and its own vacuity is checked by mutating it to compare sets instead of prefixes. diff --git a/docs/decisions/0079-cross-process-run-ownership-lease-and-fencing-token.md b/docs/decisions/0079-cross-process-run-ownership-lease-and-fencing-token.md new file mode 100644 index 00000000..7e58a2e9 --- /dev/null +++ b/docs/decisions/0079-cross-process-run-ownership-lease-and-fencing-token.md @@ -0,0 +1,157 @@ +# ADR-0079: Cross-process run ownership — a durable run lease with a monotonic fencing token (amends ADR-0036) + +- **Status**: Accepted +- **Date**: 2026-08-12 +- **Related**: + - [ADR-0036](0036-run-loop-substrate-event-bus-and-execution-host.md) — the `ExecutionHost` seam and exactly-one-terminal. **Amended here.** + - [ADR-0078](0078-ordered-durable-append-and-the-terminal-outbox.md) — the `DurableWriteContext` this extends, and the `uncertain` disposition it reuses. + - [ADR-0073](0073-history-db-migration-lock.md) — precedent only, not a component (§8). + - [ADR-0075](0075-fail-closed-resume-on-an-unreadable-event-log.md) — the nearest philosophical precedent: a resume that cannot be trusted refuses.

The only uniqueness the database actually enforces is `UNIQUE(run_id, seq)`, and `resumeFromCheckpoint` performs an **in-memory** `this.#runs.has(runId)` check before loading a checkpoint and building an independent `RunExecution`. An in-memory check is per-process by construction. + +So two `relavium` processes can resume the same paused run at the same time and become **two independent side-effect producers for one run**. Both read the same checkpoint, both dispatch the same nodes, both call the same tools. `ADR-0078`'s compare-and-append stops the second one *writing the same row* — it does not stop either of them *doing the work*, because the effect happens before anything is written. That gap is why `CR-12`'s effect journal cannot mean anything until this closes: an idempotency key is worthless when two owners each believe they are the only one. + +Three constraints shape the answer: + +1. **The engine is platform-free.** It has an ISO-string clock and no filesystem, so the mechanism cannot be an OS lock and the TTL cannot be evaluated engine-side against an ambient clock. +2. **`ADR-0073`'s migrate-lock is precedent, not a component.** It imports `better-sqlite3` (unreachable from `packages/core`), yields no token, is invisible to `listInterruptedRuns`, and ADR-0073 explicitly forbids the Postgres port inheriting it. +3. **A CAS is not enough, and the phase already settled why.** A compare-and-swap on `last_seq` stops two processes writing the same row; the *fence* is what makes a stale owner harmless **after** it loses ownership — which is the only thing that helps when the loser is mid-run and about to call a tool. + +## Decision + +**We will take a durable per-run lease carrying a monotonic fencing token, check that token inside the same transaction as every durable write, and make a process that loses its lease stop without claiming an outcome it does not know.** + +### 1. The lease is a row, in its own table + +A `run_leases` table keyed by `run_id`, holding the owner id, a monotonically increasing `generation`, and an expiry. Not a column on `runs`: that row is a **derived projection** the event fold rewrites (`applyDerived`), so putting authoritative, non-derived ownership state in it mixes two lifetimes in one row and invites a fold to clobber it. A table is also queryable — by `listInterruptedRuns`, and by a human diagnosing a stuck run. + +`generation` increments on every successful acquire — including the takeover `reconcile()` performs on an expired lease (§7) — and never resets. That is the fence: a token that only moves forward, so a stale owner's token is recognisably old rather than merely different. + +> **Amended 2026-08-17 (CR-11 implementation).** "Never resets" is not what shipped, and the sentence above +> is left standing so the correction is legible rather than silently rewritten. `release` **deletes** the row, +> so the next acquire starts at generation 1 again — and because §4 (below) releases on every gate park, that +> is the normal lifecycle, not an edge case. What actually keeps a stale owner out is therefore +> `(ownerId, generation)` **pair-equality plus fail-closed-on-a-missing-row**, not monotonicity: a writer that +> cannot produce the exact pair the row holds — or finds no row — is refused. Monotonicity holds within a +> single lease's lifetime, which is what the takeover in §7 relies on. +> +> The residual risk is named rather than left to be discovered: two claims from the same `ownerId` separated +> by a park are indistinguishable (`{E,1}` then `{E,1}`), so a long-lived host that keeps one `WorkflowEngine` +> across many park/resume cycles — the desktop app, the VS Code extension host — cannot use the token alone to +> tell a straggler from the current leg. In-process that gap is closed by the engine's own `#runs` map, which +> is the authority on what this process is running; across processes the `ownerId` differs and the pair is +> decisive. Making the token genuinely monotonic needs a tombstone (`owner_id = NULL, expires_at = 0`) rather +> than a delete, and therefore a migration, a drizzle snapshot regeneration and a permanent row per run — a +> trade worth taking only if that long-lived-host case becomes real. That is the trigger for revisiting it. + +### 2. The fence rides `DurableWriteContext` — the port is not broken again + +`ADR-0078` §2 introduced `DurableWriteContext` as one extensible object precisely so the two items after it would extend rather than re-break `persistEvent`. This is the first of them: the context gains `fence`, and nothing else about the port changes. + +The store checks it **inside the existing `BEGIN IMMEDIATE` transaction**, next to the compare-and-append and through the same `tx` handle. Outside the transaction the read and the write would be two statements another process could interleave — the exact race the check exists to close. + +Considered instead: binding the store to a lease at construction (rejected — cheaper, but it makes the fence invisible to the type system at every call site, which is how this project resolved the identical fork for `expectedLastSequenceNumber`); and a bare `last_seq` CAS (rejected — see Context 3). + +### 3. A fresh run's lease is created in the same transaction as `run:started` + +`WorkflowEngine.start()` is synchronous, so it cannot await an acquire. It does not need to: a fresh `runId` comes from `host.ids.newId()`, so the start-side lease is **uncontended by construction**. Creating the row inside the same transaction that folds `run:started` means a run either has both or neither, with no window and no API break. + +All contention is on the resume path, which is already async. + +> **Amended 2026-08-17 (CR-11 implementation).** "In the same transaction" is not what shipped: the lease is +> acquired immediately **after** `run:started` is folded, because `run_leases.run_id` references `runs.id` and +> that row is created by the fold — creating the lease inside the same transaction fails the foreign key. The +> window this opens is uncontended for the reason the section already gives (the `runId` came from +> `ids.newId()` moments earlier and no other process has seen it), so a run can have `run:started` without a +> lease only for the duration of one `await`, and only its own process can be in it. The consequence that +> matters is elsewhere and is now explicit: `run:started` is therefore written **unfenced**, because no lease +> row can exist yet — the sole exemption in §2's rule, and the reason the engine models "before the first +> acquire" as a state of its own rather than as "not owned". + +### 4. A losing resume refuses before it reads anything + +`resumeFromCheckpoint` acquires the lease **first**. A failed acquire throws a new typed `EngineStateError` naming the current holder and the remedy — before the checkpoint is loaded and before any `RunExecution` exists, so a loser never becomes a second producer even briefly. + +> **Amended 2026-08-17 (CR-11 implementation).** The paragraph below was added to this section after it was +> Accepted, and is marked rather than left to read as original text. It also proved incomplete twice over, +> and both corrections are recorded at the end of it. + +**The lease is released when the process stops WORKING on the run — which includes a re-pause, not only a +terminal.** This was under-specified when the section was first written and implementation found it: a +sequential multi-gate run resumes, re-pauses at the next gate, and the very next `relavium gate` is refused +for the full TTL by a lease nobody is using. A parked run has no process executing it, and the point of +ownership is to stop two processes *acting*. Releasing is safe because the next resume re-acquires anyway, and +the pair-equality fence of §1 still refuses a claim that does not match the row — so a stale owner stays +fenced. Every refusal path above also releases what it just took, or a run that does not exist would lock its +own id. + +**Two corrections implementation forced, both recorded here because §4's rule is what opened them.** First, a +parked run is *not* inert: its gate deadline, the run-level `timeout_ms` and cooperative cancel all stay armed +by design, and all of them end in durable writes. Releasing without accounting for that let a parked process +write a terminal into a run another process was finishing — since a terminal is exempt from the append guard +(ADR-0078 §2) and an **absent** fence is a pass rather than a refusal, the store took it. The rule is +therefore not "release and forget" but *hand the claim back and re-take it before writing again*, enforced at +the single durable-write choke point rather than at each of those callers. Second, the claim must be handed +back as part of the write that publishes the pause, not after it: `#emitDurable` delivers to consumers, and an +inline prompter resumes synchronously on `run:paused`, so a claim dropped afterwards let that resume believe +it still owned the run and then had the row deleted out from under it. + +**A typed refusal, not an observer handle.** The acceptance says the loser "degrades to observer with a typed, actionable error" — two deliverables in one phrase. **The typed error is in scope; the observer handle is not.** A real observer — tailing the durable log and synthesising a `RunHandle` stream — is a new engine capability, and `createClosedRunHandle` shows the tree already prefers a degenerate handle to a new streaming mode. The observer is recorded as a named follow-up with its trigger: the first surface that must *watch* another process's run rather than merely be refused by it. + +### 5. A fenced-out IN-FLIGHT run stops without claiming an outcome + +This is the sharpest decision in the ADR, and it is deliberate. + +A process whose lease is revoked mid-run knows it lost. It does **not** know what happened to the run — the new owner may be completing it successfully right now. So the loser: + +- **emits no terminal at all.** Writing `run:failed` would be a durable **lie** about a run another process is finishing. It could not be written anyway: the fence rejects it, which is the mechanism working. +- **closes its local stream** so the consumer's `for await` completes rather than hanging. +- **reports `durability: 'uncertain'`** — reusing exactly the vocabulary ADR-0078 §5 minted, which is what §5 said `CR-11` would do. The disposition is honest here for the same reason it was there: the run has an outcome, and this process does not know it. + +Considered instead: a local-only `run:failed` (rejected — the surface would say "failed" while the run may be succeeding elsewhere, which is the very divergence `CR-92` closed); and a new `run:fenced` terminal (rejected — it widens ADR-0036's exactly-one-terminal set and forces every surface, schema and the checkpoint fold to handle a new variant, for a state the caller learns from the handle instead). + +### 6. Expiry is evaluated store-side, on one clock + +The TTL is **60 seconds**, heartbeat every **20 seconds**. Three missed heartbeats permit a takeover: wide enough that a long provider call or disk pressure is not mistaken for death, narrow enough that a crashed run is not locked for more than a minute. + +Expiry is compared **store-side**, against the epoch-millisecond clock the store already has injected (`RunHistoryStoreDeps.now`). Every process on the machine then compares against one clock, and the engine gains no new time seam — it has only an ISO-string clock, and adding a second notion of time to a platform-free package to support a lock is the wrong direction. The heartbeat re-arms through the existing `ExecutionHost.setTimer`, the same way ADR-0045's media poll does. + +### 7. `reconcile()` becomes lease-aware here, and a lease loss has its own exit code + +`reconcile()` writes a terminal for every non-resumable interrupted run — from a process that may not own it. That is latent today (no surface calls it except `ADR-0078` §4's drain), which makes it cheap to fix now and a data-loss bug later. It skips any run holding a **live** lease; reconciling an expired-lease run **bumps the generation**, so the old owner is fenced out if it ever wakes. + +The CLI maps a lease loss to **exit code 6**, distinct from the blanket `EngineStateError` → exit 2. A lease loss is *transient and retryable*; every other `EngineStateError` (unknown run, workflow mismatch, already terminal) is a permanent invocation fault. An automation loop has to be able to tell "try again shortly" from "never call this again". The taxonomy extension is recorded in ADR-0049's canonical home. + +### 8. Scope, stated rather than left to be inferred + +- **Runs only.** `AgentSession` / `chat-resume` keeps the two-process drift ADR-0070 already recorded and accepted. The asymmetry is named honestly: ADR-0070's accepted drift is *cost-reporting* drift, while two chat processes on one session also interleave tool effects — that is a real gap, and it is `CR-12`'s and a future session-ownership item's, not this one's. +- **Local only.** One `history.db` on one machine. The Phase-2 Postgres path gets its own advisory mechanism and must not inherit this one, mirroring ADR-0073's scoping clause. +- **This does NOT amend ADR-0073.** It is precedent for "route the lock through SQLite because Node has no dependency-free `flock`", nothing more: different lifetime, different granularity, and it needs a token an OS lock cannot give. +- **This does NOT supersede ADR-0075.** Its fail-closed resume is the nearest philosophical precedent and is cited, not changed. +- **ADR-0050's durability-first posture is unchanged.** A stale-fence rejection is an **expected refusal**, not data loss: it must not be retried by `withBusyRetryAsync` and must not collapse into the fatal path — the same classification `AppendConflictError` already has. + +## Consequences + +### Positive + +- Two processes can no longer become two side-effect producers for one run, which is the precondition `CR-12`'s effect journal needs to mean anything. +- The fence makes a *stale* owner harmless, not merely a *slow* one — the property a CAS cannot provide. +- One more field on `DurableWriteContext` rather than a third break of `persistEvent`, which is what that object was introduced for. +- `reconcile()` stops being able to terminate a run another process is running, before any surface wires it. + +### Negative + +- **A new required host port and a migration.** Every host and test double must supply the lease port; the schema gains a table and `tools/db-sync` needs its snapshot regenerated. Mitigated by an in-memory reference implementation shipped with `createInMemoryHost`, following the `newAbortController` and `TerminalOutbox` precedents. +- **A heartbeat is a timer on every run.** Cheap, but it is real work on the hot path and one more thing that must be disarmed on settle. The existing `setTimer` seam and its disarm contract carry it. +- **60 seconds of lock after a crash.** A run whose process died is not resumable for up to a minute. That is the cost of not mistaking a slow run for a dead one, and the number is stated here so it can be changed with evidence rather than by feel. +- **A fenced loser reports `uncertain` and writes nothing**, so a user watching that process sees the run stop with no terminal of its own. That is honest — the run's real outcome is in the durable log the new owner is writing — but it is a new thing for a surface to explain, and the CLI's exit code 6 is what makes it actionable rather than merely puzzling. +- **The two-process race cannot be proven in one Node process.** `better-sqlite3` is synchronous, so in-process concurrency is serialized by construction. The regression follows `migrate-lock.e2e.test.ts`: spawn real children, and be **visibly skipped** rather than silently passing when the build output is absent. +- **The observer handle is deferred**, with its trigger named in §4.

The target sees the effect twice — a duplicate ticket, deploy, payment, message or commit. `ADR-0079` closed +the precondition (two processes can no longer both own a run); this closes the effect itself. + +Three facts about the tree shape the answer, and all three were verified rather than assumed. + +**The dispatch surface is one chokepoint with two producers, not three peers.** `registry.ts` is the only place +where the validated args, the assembled effective args and the resolved policy target exist at once. The two +producers are the model-driven turn and the `!`-shell user command. Instrument one site; thread two contexts. + +**No identity is reachable there today.** `ToolDispatchContext` carries `nodeId` and nothing else that identifies +an occurrence — no `runId`, no `sessionId`, no attempt of either family. On the session path `nodeId` is the agent +ref, constant for the session's whole life, so it is not even a per-effect discriminator. + +**Neither attempt counter can key anything.** The counter that reaches the dispatch is the within-chain provider +failover count, not the node-retry count. And the node-retry count — which does exist, ADR-0040 shipped it — +restarts at 1 both on a crash-resume and on a budget approval, so `(runId, nodeId, nodeAttempt)` repeats. + +The phase document proposed one key, `runId + nodeId + nodeAttempt + toolCallId + effectiveArgsHash`. It cannot +work: every retry and every resume mints a new value, so the journal can never deduplicate and "safe retry under +the same key" is unimplementable. It also contradicts two already-canonical sentences in +[action-guard-seam.md](../reference/shared-core/action-guard-seam.md) that name the retry attempt as replay +correlation and explicitly *not* the idempotency key. + +## Decision + +**Every effectful tool dispatch is bracketed by a durable prepare/settle pair in a new authoritative +`effect_journal` table, addressed by a discriminated `EffectCorrelation` that neither entry point can fabricate +for the other.

It carries the table's + UNIQUE constraint and answers *"is this row about the same effect occurrence as that one?"* — which is what + makes two processes preparing the same effect collide rather than both dispatch. It is **not** claimed to be + reproducible after a model replay; §2 says exactly what it is and is not. +- **`EffectAttemptId`** — the audit row: the node-retry attempt, the provider attempt, the tool-call id, and the + owner/generation that produced it. It answers *"which occurrence was this?"* and is never used for dedup. + +Both hang off **`EffectCorrelation`**, a discriminated union — `{ kind: 'run', runId, nodeId, attempt }` or +`{ kind: 'session', sessionId, turn }` — mirroring the invariant the run-event envelope already enforces at +runtime, where exactly one of `runId`/`sessionId` must be present. A session never fabricates a `runId`; a run +never borrows a session's. That is the property ADR-0024 protects and the reason the union exists rather than an +optional field. + +Considered instead: the phase doc's single key (rejected — see Context); recomputing the identity on replay to +match the journal (rejected — the model regenerates its args, and a provider failover regenerates them on a +*different* model, so the recomputed value is not the stored one); and `RunFence.generation` as the occurrence +epoch (rejected — a same-owner renewal bumps it and a gate park re-acquires, so it would suppress legitimate +second effects at every park boundary). + +### 2. There is no universal replay-stable identity, and the guarantee does not depend on one + +Identity-level dedup works only where the args are **byte-stable across a replay**. Exactly one dispatch site in +the tree has that property: the `!`-shell command, whose args come from the user's typed line. Everywhere else the +args are model-generated, so a replay produces a different digest for the same logical intent — and a provider +failover regenerates them on a *different model*. + +So this ADR does **not** claim a universal replay-stable logical identity. Claiming one is what made the phase +document's single key unimplementable, and the same trap is available here. Five separate concepts are named +instead, because collapsing any two of them is where the design goes wrong: + +| concept | what it identifies | replay-stable? | +|---|---|---| +| **`EffectCorrelation`** | the run/node or session/turn the effect belongs to | yes, minus the attempt | +| **`EffectSlot`** | *which* effect within that correlation (an ordinal over the turn's tool calls) | only within one model response | +| **`EffectAttemptId`** | this one occurrence, for audit | no, by design | +| **`effectiveArgsDigest`** | a collision guard and audit fingerprint | no, except at the `!`-shell | +| **target idempotency key** | what a tier-1 target dedups on | supplied to the target, never derived from the model | + +**The primary guarantee is a resume gate at node granularity, not a digest match.** Its lookup key is the +correlation **with the attempt dropped** — because the node-retry attempt resets to 1 on a crash-resume and on a +budget approval (Context), so an attempt-scoped lookup would miss the very row it exists to find. + +### 2b. The gate examines every prior effect record, not only the unresolved ones + +The obvious form of this gate — "an unresolved row blocks the re-run" — leaves the main crash window open, and +this ADR closes it explicitly because an earlier draft did not: + +> prepare persists → the effect succeeds at the target → the row settles `committed` → the process dies before +> the tool result or `node:completed` persists → resume sees a *resolved* row, does not block → the model +> regenerates the call → **the effect fires a second time.** + +A `committed` row is therefore not a green light. On resume, for a correlation with **no terminal node record**, +every prior non-benign effect record is examined and resolved by tier: + +| record state | tier | resume behaviour | +|---|---|---| +| `committed` **with a replayable stored result** | any | re-deliver the stored result; do **not** re-execute | +| `committed` **without** one | 1 | safe retry under the same target idempotency key | +| `committed` **without** one | 2 | reconcile from a receipt lookup, then decide | +| `committed` **without** one | 3 | `needs_attention` — never re-executed | +| `prepared` / `dispatched` / `ambiguous` | 1 or 2 | reconcile, then decide | +| `prepared` / `dispatched` / `ambiguous` | 3 | `needs_attention` | + +The rule that makes this safe to state: **if the journal did not retain enough to re-deliver the result, a +`committed` row blocks the node exactly as an unresolved one does.** Storing the result is what buys the +re-delivery, and where it is not stored the answer is refusal, never a silent re-run. + +### 3. Three tiers, and today every shipping effect is tier 3 + +1. **Target accepts an idempotency key** → safe retry under the same key. Effectively exactly-once, and the only + tier that may say so. +2. **Target's outcome is queryable** → reconcile from a receipt lookup before deciding. Exactly-once after + reconciliation. +3. **Opaque, non-idempotent** → `dispatched → ambiguous → needs_attention`. **Never auto-retried.** + +Tiers 1 and 2 are **reserved and fully specified, and claimed by nothing**. No shipping capability offers a +receipt lookup, and no tool injects an idempotency key. Saying this plainly is the point: the ADR's headline is a +*narrowing* of the product claim, not a new capability, and a reserved tier that no code occupies is honest where +a tier assigned by aspiration is not. + +`http_request` is the nearest promotion — the egress header filter is a denylist, so an `Idempotency-Key` already +passes the wire — but the missing half is *who asserts that a given target honours it*, and that assertion is a +schema change the engine cannot verify. Shipping the first promotion beside the floor would make the first +promotion bug and the first journal bug arrive together and be indistinguishable. Deferred with its trigger: the +first user with a real webhook or payment target. + +### 4. MCP is tier 3, permanently, and the reason is not a missing feature + +Discovered MCP tools carry no usable annotations, and any that existed would be attacker-controlled bytes from the +very server the hostile-MCP class defends against. An annotation may never *raise* trust. Tier 3 is therefore not +a temporary state pending better metadata — it is the correct terminal answer for a tool whose semantics are +declared by an untrusted party. + +An author-declared per-tool promotion (author trust, not server trust — the shape `allowedCommands` already uses) +is a coherent future escape hatch and is recorded as a follow-up rather than shipped here, for the reason in §3. + +### 5. A benign-under-duplication property, declared rather than excepted + +`notify` is a side effect by the letter of the contract and absurd under it: a duplicate desktop toast is not an +incident, and halting a run for one would discredit the whole mechanism. The answer is a declared +`duplicationBenign` property on the tool definition, with `notify` as its only member today — not a one-line +exception in the predicate. A one-line exception is the shape that decays: the next tool with the same property +earns a second exception somewhere else. A declared property makes the predicate a lookup and forces the next +author to state the claim rather than inherit it. + +### 6. An unresolved tier-3 row stops the run; a session discloses instead of blocking + +On resume, an unresolved row for this correlation means the node is **not re-run**. The row becomes +`needs_attention` and the run terminates with a distinct disposition. A human decides. + +> **Amended 2026-08-18 (CR-12 implementation).** "A distinct disposition" was implemented as a distinct +> **`ErrorCode` on `run:failed`** and a distinct CLI **exit code 7** — not as `RunHandle.durability()` +> reporting `'uncertain'`, which is what §6 of the canonical spec said before this landed.

The engine therefore reads every re-runnable node's rows before +> anything is scheduled. Re-DELIVERY stays at the dispatch, because only the host can compute the args +> digest the comparison needs. + +The session path departs deliberately, and this is the one place this ADR reads the phase document's +`needs_attention` less than literally. A chat session has no operator queue and no run to pause; blocking the next +turn would be an interruption where the honest answer is information. So `chat-resume` **reads its unresolved rows +and discloses them once**, and does not block. That keeps tier 3's actual guarantee — never auto-retried, because +nothing re-dispatches them — while putting the fact in front of the one person who can act on it. + +Considered instead: continuing with a durable "possible duplicate" warning (rejected — that is today's behaviour +with better logging, and it cannot satisfy the acceptance criterion); and an author-declared per-node +`on_ambiguous: replay` escape (rejected for now — it is a promotion mechanism, and promotions ship after the floor +is proven; trigger: the first user who reports a run they would rather have replayed). + +### 7. The seam: a required port on the dispatch context, not a fourth store method + +The journal port is injected on `ToolDispatchContext` with the correlation **already closed over**, mirroring +`TurnMoneyPort` — the engine stamps the identity because only the engine knows it, exactly as only the run loop +can supply the ledger's `runId`. This *extends* that precedent rather than reusing it: the money port is run-path +only, and this one must be supplied by both entry points. + +**Two barriers, at different granularities — and ADR-0077 predicted this one's placement wrongly.** That ADR +put its money barrier at `agent-turn.ts`'s single `await dispatchToolCalls(...)`, deliberately *"rather than +inside `ToolRegistry.dispatch`"*, and then said the effect journal's state machine *"has to be written at exactly +this point in exactly this path."* It does not. A model turn dispatches a **loop** of tool calls, so a checkpoint +that runs once per turn cannot record which individual effect was prepared, dispatched or settled. The money +barrier is per-TURN and stays exactly where ADR-0077 put it, for exactly its reasons; the journal is per-EFFECT +and must sit at the one place a single effect is visible. ADR-0077's own stated worry — that per-call placement +"would have to be re-proven for every dispatch path" — is answered by the fact established in Context: there is +one sink, not a path per producer. + +Considered instead: a fourth `RunStore` method (rejected — ADR-0079's own precedent made the lease a separate port +for the same reason, and `RunStore` is deliberately three methods); a required port on `ExecutionHost` (rejected, +and this is the closest precedent so it is argued explicitly — `ExecutionHost` is the *run's* host and does not +reach `AgentSession` at all, which is the one property the session decision requires); and an optional port +(rejected on ADR-0078 §4's exact reasoning — optional would mean a host that forgets it silently has no +guarantee, a fail-open default inside a fail-closed item). + +The journal must **not** ride `#emitDurable`. That path is deliberately total for non-terminal events, so a UNIQUE +violation — which is the *successful* detection of a duplicate — would be swallowed and reported as a run failure. +It also cannot be a `RunEvent`: `run_events.run_id` is `NOT NULL` with a foreign key, and the store throws on a +session event. + +### 8. Where the commit write sits, and why that placement is load-bearing + +The dispatch ladder's `try` block ends in a classification that maps a throw to `tool_failed`, which is +**node-retryable**. A commit write placed inside it would mean a journal failure triggers the very duplicate the +journal exists to prevent. The settle write therefore sits outside that ladder, and this ADR amends ADR-0037 to +say that a side-effecting host throw is no longer node-retryable. + +### 9. Composition, retention, and the durability scope + +The journal write repeats ADR-0079's fence check inside its own `BEGIN IMMEDIATE`, using the run-history store's +check as the template, so a fenced process cannot journal an effect either. The row carries **no foreign key** to +its run: an `ambiguous` row is precisely the record an operator needs *after* the run is purged. Committed rows +are swept; **unresolved rows are never swept**, following the media-object grace precedent — without that, the +journal is the fastest-growing table in `history.db`. + +The guarantee is **process-crash durability, not power-loss**: the database runs `synchronous = NORMAL`, and +CR-12's own failure statement is process death. Claiming power-loss durability by silence is the class of +overclaim this phase exists to remove. + +### 10. CR-95: a mid-tool-loop budget pause is forbidden, and fails closed + +A budget pause mid-tool-loop resets the node to pending and re-dispatches it from the start, repeating earlier +provider *and tool* calls — a duplicate-effect amplifier that this ADR's journal would otherwise have to absorb. +The short-term fix is non-deferrable and is decided here: **a budget pause is refused while a tool loop is in +flight, and the run fails closed instead.** + +Precisely: a turn's tool loop is "in flight" from the moment its **first** tool call is dispatched until the +turn ends — not merely until that call settles. The distinction is the whole point, because the pause can only +arrive at a provider egress, which is *between* tool rounds: by then the earlier round has settled, and it is +exactly those settled effects that an approval would replay. So from the second provider egress of a turn +onward, a budget verdict that would pause does not pause — it fails the node terminally with the budget error, +**without replaying any earlier effect and without a further provider egress**. The first egress still pauses +normally: nothing external has happened yet, so a replay costs one provider call and the pause stays useful. The alternative shapes both lose: completing the loop past the cap spends money the user +capped, and pausing-then-resuming is the replay this item exists to remove. Failing closed is the only option +that neither overspends nor duplicates, and it is deliberately the more disruptive of the honest choices. + +This fix does **not** depend on the journal and should land first: it removes the amplifier that would otherwise +generate the duplicates the journal has to absorb. + +The long-term continuation checkpoint (provider messages, tool call/result pairs, round index) is a new +durable artifact of a different shape and is deferred with its trigger: a user who must resume a partially +completed tool loop rather than fail it. + +## Consequences + +### Positive + +- The duplicate-free claim becomes true where it is claimed, and where it cannot be true the documents say so. +- The crash window closes at node granularity for every tier, without depending on args being reproducible — the + property that makes a hash-only design fail silently. +- One chokepoint carries the guarantee, so a future dispatch producer inherits it rather than having to remember it. +- `CR-95`'s amplifier is closed in the same decision that would otherwise have to tolerate it. + +### Negative + +- **Two durable writes per effectful dispatch where there were none.** Both are small single-row writes, but they + are on the hot path and the prepare must land *before* the effect, so it cannot be batched away. +- **Every shipping effect is tier 3**, so a crash during one halts the run and requires a human. That is strictly + more interrupting than today — where the same crash silently duplicates — and it is the trade this ADR makes + deliberately. +- **A release note that narrows a claim.** No new capability ships; what ships is an honest floor and the removal + of a promise the code never kept. +- **The session path ships without an ownership guarantee.** ADR-0079 is runs-only, so two `chat-resume` processes + on one session can still both dispatch; the journal's UNIQUE prepare detects it but cannot distinguish a live + prepare from a dead one. Recorded as a limitation with its trigger: the first supported concurrent-resume flow. +- **A credential rotation mints a fresh identity**, so an effect whose args include a rotated reference degrades to + tier-3 behaviour for that occurrence.

On the next tool-capable turn those bytes sit in `system`, and because the +summary is persisted they survive a restart and a model reseat. **An XML fence is not a +trust boundary** — it is a formatting convention that the untrusted text can close. + +This directly contradicts [security-review.md](../standards/security-review.md), which +treats model output and tool results as untrusted and forbids concatenating untrusted +content into `system`. ADR-0062 §1 is Accepted, so this is a superseding decision, not a +patch. + +**ADR-0062 §1's rejection of the alternative must be answered, not ignored.** It rejected +injecting the summary as a transcript message because *"a summary message either forces an +`assistant`-first array Anthropic rejects, or sits next to the next real `user` turn as two +consecutive user messages"*. Verified against the tree: + +- The **two-consecutive-user-messages half was already false when it was written.** + `packages/llm/src/adapters/anthropic.ts`'s `mergeAdjacentSameRole` folds consecutive + same-role messages into one with concatenated content blocks, and its docblock says it + exists so "adjacent user messages the API would 400" are fixed at the seam. `git log -S` + dates it to `1abd68c5`, **2026-06-14 — three weeks before ADR-0062**. +- The **`assistant`-first half is still genuine.** A design that puts the summary in its own + leading message must not produce an `assistant`-first array. + +One guarantee must **not** be overclaimed. The OpenAI adapter joins content parts on the +wire (`parts.map(...).join('')`), so "the bytes arrive as a separate part" is false there. +The guarantee available on every adapter is the **role boundary** plus an explicit in-band +separator — never a wire-level part boundary. + +## Decision + +**We will carry the compaction summary as untrusted content inside the first user-role +turn, and make `system` a branded type that only the authored-prompt builder can +construct** — so the compiler, not a convention, enforces the boundary. + +### 1. `AuthoredSystemPrompt` — a branded string with a CLOSED set of constructors + +`AgentTurnParams.system` and the session's system builder stop accepting `string`. They accept +`AuthoredSystemPrompt`, a branded type produced only by a closed-arm constructor: + +``` +authoredSystemPrompt({ kind: 'agent', agent, node? }) // agent.system_prompt + node.system_prompt_append +authoredSystemPrompt({ kind: 'engine', prompt: 'compaction' }) +``` + +**The second arm is not an escape hatch and takes no arbitrary string.** It takes a closed union of +engine-owned prompt IDENTITIES and returns the corresponding engine-owned constant. It exists because the +engine genuinely has a third authored producer, and a draft of this ADR missed it: `COMPACTION_SYSTEM_PROMPT` +(`packages/core/src/engine/agent-session.ts`) is passed as `system` on the summariser call. Without the arm, +that call site would have to reach for an `as`, fabricate an `Agent`, or add the very second constructor the +rule forbids — so the honest design names the producer rather than pretending there are two. + +Considered: a runtime assertion that the assembled `system` contains no summary bytes (rejected — it is a +scan for a payload whose shape we already know, and it fails open on any encoding the scan misses); a naming +convention plus a review checklist (rejected — that is exactly what was in force when ADR-0062 §1 shipped); +and a `readonly` wrapper object (rejected — it changes the seam shape for no additional guarantee, since a +brand is erased where the string is finally read). + +The brand is a compile-time device with **zero runtime cost and zero seam impact**: `LlmRequest.system` +remains `z.string().optional()`, and the branded value is a string. What changes is that a dynamic string +can no longer reach the field through ordinary typed code. + +**What the brand does and does not buy, stated precisely.** A brand is nominal to the type-checker but not +to a deliberate `as` — `dynamicString as AuthoredSystemPrompt` compiles, and a draft of this ADR wrongly +claimed the repo's lint rules stop it. They do not: `eslint.config.mjs` bans `any` and restricts seam +imports, and has no assertion ban. So the mechanism ships WITH its fence: `no-restricted-syntax` selectors +in the same slot as the existing seam and machine-output fences, covering a `TSAsExpression` or +`TSTypeAssertion` naming `AuthoredSystemPrompt`; a type-ALIAS declaration naming it, because a name-based +selector is otherwise defeated by one hop of indirection; and a type PREDICATE naming it, which needs no +assertion at all — `value is AuthoredSystemPrompt` narrows a plain string into the brand, type-checks +cleanly, and reads exactly like the legitimate `isBilledModality` guard already in `agent-runner.ts`. That +last one was the most important to close precisely because it is the most legible: the other forms keep the +brand's name beside an assertion, where a reviewer scanning for `as AuthoredSystemPrompt` has a chance. + +**What the fence does not catch, stated rather than left to be found.** A generic cast helper +(`function id(v: unknown): T { return v as T }`, called as `id(x)`) launders any +brand, as does an interface field typed as the brand plus an object assertion. Both were verified against +the shipped config. Neither is reachable by accident: each requires writing a construct whose only purpose +is to defeat the type, and TypeScript offers no defence against `as` short of a runtime wrapper — which §1 +rejects for changing the seam shape. The claim is therefore exactly: **ordinary typed code cannot reach +`system` with a dynamic string, and a deliberate forgery is visible.** Not "impossible". + +The type and its constructors live in `packages/core` beside the message assembly that consumes them, not in +`packages/shared` — exporting the constructor from the shared barrel would widen the surface that can mint +one to every package and surface, for a contract that has exactly two consumers, both in the engine. + +### 2. The summary is `Untrusted` from the moment it exists + +A brand on the `system` SINK narrows the documented attack. It does not make the summary itself untrusted, +and the binding standard ([security-review.md](../standards/security-review.md)) asks for the content to +carry its provenance, not merely for one sink to be guarded. So: + +- the in-memory summary field is `Untrusted`, using the existing `packages/core/src/tools/untrusted.ts` + primitive — **no new security primitive**; +- the summariser's result is `markUntrusted(...)` at the moment it is read off the model; +- persistence stores the raw string (the durable row shape does not change), and the RECONSTRUCTION boundary + re-marks it — a value that comes back off disk has not become trustworthy by being stored; +- exactly **two** places unwrap it, and both are `user`-role positions: the request-assembly helper in §3 + (`buildTurnMessages`), and `renderConversationToSummarise`, which folds a prior summary into the next + summarisation call. A draft of this section said "exactly one place" and was wrong about its own audit + surface — the second site is equally load-bearing, and an auditor who grepped only the first would have + missed it. + + **That count is a discipline, not a structural bound, and the asymmetry with §1 is deliberate.** + `Untrusted.value` is an ordinary readable property; `unwrapUntrusted()` is sugar for reading it, and + nothing stops a future call site from reading `.value` directly — neither a grep for `unwrapUntrusted` nor + any lint rule would surface it. The `AuthoredSystemPrompt` SINK is fenced (§1); the untrusted CARRIER is + not, because that fence would need type information a syntactic selector does not have, and because the + primitive is pre-existing (1.T) and this ADR deliberately introduces no new security primitive. The two + halves carry different strengths, and saying so is worth more than a count that reads stronger than it is: + the sink is enforced, the carrier is conventional. + +The persisted marker row's `role: 'system'` (ADR-0062 §2) is a **storage encoding and nothing more**. No +consumer may read it as LLM system authority. That sentence is the one this ADR most needs on the record, +because the row's role name is precisely what would invite the defect back. + +The field is renamed from `#contextPreamble` to `#compactionSummary`. "Preamble" names the thing this ADR +removes, and a name that describes the old placement is how the next reader reintroduces it. + +### 3. One pure projection assembles the turn, and it never mutates the transcript + +``` +buildTurnMessages( + summary: Untrusted | undefined, + messages: readonly LlmMessage[], +): LlmMessage[] +``` + +The rules are normative, because the alternatives are real bugs rather than style: + +- **The join happens at REQUEST ASSEMBLY, never in `#messages` and never in the durable transcript.** + Mutating `#messages` would make the summary part of the real conversation: the next compaction would fold + it a second time (once as the standing summary, once embedded in the first user message), the persister + would write it as user text, and every turn would re-prefix it. +- **The helper is pure.** It clones the first user-role message rather than editing it, and returns a new + array. +- **The summary block is a text content part prepended inside the LEADING user message** — or its own + leading user message when the transcript does not start with one. That answers ADR-0062 §1's surviving + objection STRUCTURALLY rather than by assumption: the returned array is user-first for every input, so no + leading `assistant` is reachable and no second consecutive `user` message is created. An earlier form + embedded into the first user message wherever it sat, which left `[assistant, user]` still + assistant-first — unreachable through any live caller, but a property of four separate caller invariants + rather than of this helper, and therefore one the next caller would break. +- **The separator is in-band and explicit**, because the OpenAI adapter joins parts on the wire and a part + boundary is invisible there. Its exact text has one canonical home — [chat-session.md](../reference/cli/chat-session.md) + § Context compaction, where ADR-0062 §7 already put the summariser prompt — and is derived from there, + never restated. It states the block's provenance in plain prose and identifies the text after it as the + user's message; nothing in the block is presented as instruction. +- **When there is no first user-role message**, the helper prepends one carrying only the summary block. + That case is reachable (a resumed session whose next action is a tool-result-only turn), and it must be + defined rather than discovered. +- **The same helper serves every path** — a normal turn, a restore, a reseat, and the token estimator. The + estimator measuring a different array than the request is how a context-window guard drifts from the + request it is guarding. +- **The summary is never double-prefixed.** The helper is the only producer, it runs once per request, and + it reads the session's single summary field — so a second compaction replaces that field rather than + nesting. + +### 4. Tool authorization is computed from policy alone + +The granted tool set comes from the agent's `tools` list and the node's grant. It never reads the summary. +This is called out because "the summary cannot escalate" is the claim a reader most needs proven, and §6's +acceptance criteria require it proven by mutation rather than asserted here. + +### 5. What is NOT decided here + +The brand covers the engine's system-prompt producers. It does not retroactively audit every other string +the engine builds; a future untrusted-content carrier gets the same treatment when it is written, not by a +sweep promised here. The `Untrusted` marking covers the compaction summary specifically — other model +output already has its own handling and is out of scope. + +### 6. Acceptance criteria + +Structural and type-level only, per the phase's working-discipline clause 6. Stated here, not by reference, +because this repo treats the ADR as the contract the implementation is verified against. + +1. A type-level test proves a dynamic `string` cannot be passed as `system`, and that the brand's + constructors are the closed set in §1. +2. The lint fence in §1 is verified against the SHIPPED config, by an exact error count on a quarantined + fixture — the mechanism this repo already uses for its seam fence, so a partial regression changes a + count instead of passing on the remaining errors. The count is asserted in BOTH directions: fewer means a + forging form stopped being policed, more means the fence now catches one of the residuals named above and + this ADR's statement of its own bound needs correcting. +3. Given a summary containing a fence-closing sequence plus instructions, the assembled request has those + bytes in a **user-role content part** and **zero** occurrences in the `system` field — asserted on the + built request before any provider call, and again **after a restore from persistence** and **after a + model reseat**. Both re-assertions are required because the original defect survived both. +4. `buildTurnMessages` does not mutate its inputs, and `#messages` after a request is byte-identical to + `#messages` before it. +5. The token estimator and the request are built from the same projection. +6. A test mutates the summary text arbitrarily and asserts the resolved tool set is **byte-identical**. +7. **No assertion of the form "the model did not obey the injected instruction."** + +### 7. Landing obligations + +These are part of the change, not follow-ups — ADR-0080 landed Accepted with its canonical homes lagging, +and that is the pattern this list exists to prevent: + +- ADR-0062: a dated `> Superseded (§1) by [ADR-0081]` note; its `Related` line describing ADR-0059 as + carrying "the preamble" corrected. +- ADR-0059: a dated amendment saying what a reseat now carries and where. +- [chat-session.md](../reference/cli/chat-session.md) § Context compaction: the "session-level preamble + (prepended to the agent's system prompt each turn)" sentence replaced, and the separator text's canonical + home established there. +- This ADR's status moved to Accepted with the index row updated to match. + +## Consequences + +### Positive + +- The documented attack stops working structurally rather than by filtering: there is no + concatenation left to escape out of. +- The guarantee is enforced by the compiler at every present and future call site, which is + strictly stronger than the convention that was in force when the defect shipped. +- No seam change, no new dependency, and no new security primitive — `LlmRequest.system` is untouched, the + brand is erased, and the taint reuses the engine's existing `Untrusted`. +- The rejected alternative from ADR-0062 §1 is engaged on its own terms, and half its + ground is shown to have been false at the time. + +### Negative + +- **The summary carries less weight with the model.** Moving instruction-adjacent context + out of `system` is a deliberate loss of authority, and a session may follow its summary + slightly less closely.

Accepted 2026-08-18 after two review rounds; the maintainer's two blockers (rule 7's missing node-retry half, and a cooperative signal mistaken for a deadline) and the second round's correction — that the chain ALREADY tracks commitment — are all folded into the text above. The §13 obligations land with the implementation. + +## Context + +Two gaps that share one question. + +**The stream has no stated grammar, so nothing verifies one.** `StreamChunkSchema` types individual chunks and +says nothing about their ORDER: `stop` and `error` are both terminal arms, and the schema is equally happy +with two of them, neither of them, or content after one. `FallbackChain.#runEntryStream` iterates the +provider's chunks, records `usage` if it happens to see a `stop`, and on a clean end-of-iteration falls +through to `usage === undefined ⇒ #emitSuccess`. A stream that simply stops is a successful attempt whose +partial text becomes a completed assistant answer, and `fallback-chain.test.ts`'s *"records a content-free +success with no usage when the stream omits a stop chunk"* pins exactly that. + +The phase document's framing of this was wrong in a way that moves the fix, and both halves of the correction +matter. + +*It claimed the adapters do not detect a truncated stream.* They do: `anthropic.ts` tracks `sawStop` and emits +a `transport` error on a no-terminal EOF, and `openai.ts` and `gemini.ts` do the same with `sawTerminal`. A +real transport cut against a first-party provider is already classified today. + +*And this ADR's own first draft claimed the chain has no commitment tracking.* It does. `isContentChunk` is +already defined as *"anything other than the terminal `stop`/`error` arms"*, `StreamAttemptState.committed` is +already set from it, and `if (attemptState.committed) return 'done'` already prevents failover past content — +pinned by *"commits the stream on a non-text content chunk (tool_call_start), preventing failover"*. Writing +that mechanism into this ADR as new would have invited a second, competing tracker. + +So what is actually missing is smaller and sharper than either draft said: + +1. **`FallbackChain` has no trust boundary.** It accepts any `LLMProvider`. The audited adapters are not the + only implementations: `cassetteProvider` and the test doubles are providers, and Phase 2's + `ManagedGatewayProvider` will be one. A rule enforced only inside implementations we happen to own is a + coincidence, not an obligation. +2. **The chain's success path never asks whether a terminal was seen.** `usage === undefined` means "nothing + to fold" and is treated as "the attempt succeeded". +3. **Commitment stops at the chain.** It suppresses FAILOVER and travels no further, so the node-retry budget + above the chain re-dispatches a node whose provider call already produced content and already billed. + +**And no attempt has a deadline we own.** The chain awaits `generate`/`stream` with the caller's signal and +nothing else. `list-models` and key validation both bound themselves (`VALIDATE_KEY_TIMEOUT_MS`); a real turn +does not. Absent a node or run timeout the vendor SDK's default becomes the product's liveness semantics — +which [security-review.md](../standards/security-review.md) forbids for an outbound request, and which is not +a semantics we chose or can state. + +The two land together because they share one question — *had this attempt already produced content?* — +and answering it in two places would let the answers drift. + +## Decision + +**We will state the stream grammar as a seam obligation, verify it in `FallbackChain` where the seam is +crossed, carry content-commitment past the chain so the node-retry budget can honour it, and give every +attempt a HARD deadline rather than a cooperative one.** + +### 1. The grammar + +Normative for every `LLMProvider.stream` implementation. Canonical home: +[llm-provider-seam.md](../reference/shared-core/llm-provider-seam.md). + +1. **Exactly one terminal per stream:** `stop` **xor** `error`. +2. **The terminal is the last chunk.** +3. **No chunk of any kind after the terminal.** +4. **Two `stop`, `stop` + `error`, or two `error` are violations** — the caller-side restatement of 1 and 2, + kept separate because it is the shape a broken implementation actually produces. +5. **A clean EOF with no terminal is an error, never a success.** +6. **An empty stream — EOF with no chunks at all — is an error.** +7. **A pre-content failure may fail over; a content-committed failure must not fail over AND must not be + node-retried.** It is surfaced. + +**"Content-committed" means: any chunk other than `stop` or `error` has been yielded.** Not "content or +`*_delta`" — that phrasing left `reasoning_start`, `tool_call_start`, `media_start` and a provider-executed +`tool_result` undecided. The definition above is what `isContentChunk` already implements and what the +existing `tool_call_start` test already pins, so this ADR is recording the shipped rule, not changing it. + +### 2. Classification is a table of DISJOINT cases, not one per rule + +The rules above overlap by design — an empty stream violates 1, 5 and 6 at once; `stop → text_delta` violates +2 and 3 — so "one error class per rule" is not expressible and "one fake provider per rule" is not a testable +acceptance criterion. What a verifier needs is a decision procedure. This is it, evaluated in order: + +| observed | classification | +|---|---| +| a chunk arrives after a terminal | `protocol` | +| a second terminal arrives | `protocol` | +| EOF, ≥1 non-terminal chunk seen, no terminal | `transport` | +| EOF, zero chunks at all | `transport` | +| EOF, exactly one terminal, last | *well-formed* — the terminal's own semantics apply | + +**Why an empty stream is `transport` and not `protocol`.** It is operationally indistinguishable from a +connection that opened and died, which is what `transport` names. Classifying it as a protocol violation also +created a live inconsistency: the adapters' retained `if (!sawStop)` check fires unconditionally, so a +zero-chunk first-party stream already becomes a well-formed single `transport` error — while a foreign +zero-chunk stream would have become `protocol`. Same fault, opposite verdict, in direct contradiction of §3's +own reasoning. Classifying rule 6 as `transport` removes the divergence with no adapter change, and it is the +more honest reading besides. + +An immediate provider `error` as the first and only chunk stays well-formed and keeps its own kind — the +verifier cannot tell that from a synthesized truncation error, and must not try. + +### 3. `FallbackChain` verifies; the adapters keep their checks as defence in depth + +The chain wraps every provider iterator in a verifier applying §2's table. It is the only enforcement point +that matters, because it is the only one on the seam rather than inside one implementation of it. + +The adapters' `sawStop`/`sawTerminal` checks are deliberately **kept**: they produce a better-attributed error +(the adapter knows it was reading an SSE stream), and they classify a first-party truncation before it reaches +the verifier. Two layers detecting one fault is not duplication here — one is a contract check on an untrusted +input, the other a diagnostic on a trusted one. + +Considered and rejected: enforcing in the adapters only (the status quo, which leaves every foreign provider +unchecked); enforcing in `packages/core`'s turn loop (too late — the chain has already emitted a success +record and folded usage, and the turn loop cannot see chunk order across a failover); tightening +`StreamChunkSchema` (a per-chunk schema cannot express ordering). + +### 4. Rule 7 has TWO halves, and only one of them is shipped + +**The failover half already works.** `attemptState.committed` suppresses it, as above. This ADR does not +change it and does not add a second tracker. + +**The node-retry half has no carrier, and that is this ADR's most consequential fix.** A content-committed +`timeout` or `transport` failure is surfaced with its own kind — and both are in `RETRYABLE_KINDS`, so +`retryable: true`. `agent-turn`'s `throwMappedChainError` copies that onto `AgentTurnError`, and the engine's +`#shouldRetry` gates purely on `error.retryable`. So: + +> `text_delta` → `timeout` → the chain correctly refuses to fail over → the node layer re-dispatches anyway → +> a second answer, a second charge. + +Adding the `protocol` kind does not help: it covers grammar violations, not the ordinary transient failures +that make up almost all of this case. + +**The decision: `LlmError` gains an optional `contentCommitted?: true`, set by the chain when it surfaces a +failure past the first non-terminal chunk, and folded into retryability where chain failures enter the turn +taxonomy** (`retryable && contentCommitted !== true`). + +Considered and rejected: **overriding `retryable: false` on the error** — the simplest change, and it breaks +the invariant `makeLlmError` establishes, that `retryable` is a pure function of `kind`. A reader who then +sees `kind: 'timeout', retryable: false` has no way to tell a deliberate suppression from a bug, and the +reason is nowhere in the value. **A separate failure envelope around the `LlmError`** — a larger seam change +that every consumer would have to unwrap, for one bit. **Leaving it to each surface** — the fail-open this ADR +exists to close. + +The cost is honest and stated: one more optional field on the seam's error type, and one fold site that must +not be forgotten. §12 pins both. + +### 5. The deadline is HARD, not cooperative + +An `AbortSignal` is a request, not a guarantee. A provider that ignores it — + +```ts +generate(): Promise { return new Promise(() => {}); } +``` + +— or whose iterator's `next()` never settles leaves the chain waiting forever, which is exactly the hang the +item exists to remove. The repo already knows this: `safe-egress.ts` and the CLI's key validation both race a +cooperative abort against a hard timer rather than trusting the signal alone. + +So: + +- The attempt runs under a signal that aborts on EITHER the caller's signal or the deadline, **and** the + awaited promise is hard-raced against the deadline. +- **Streaming races the same ABSOLUTE deadline against every `next()`**, and does not reset it per chunk. A + per-chunk reset would let a provider dribble one token per interval forever. +- On timeout the iterator's `return()` is called best-effort and **not awaited without bound** — a hung + iterator must not hang the cleanup too. +- A late result or chunk arriving after the deadline is **discarded**, and produces no second attempt record + and no cost update. +- **The guarantee is chain and caller liveness, not resource termination.** An uncooperative provider's work + may continue in the background; what is bounded is how long Relavium waits. Saying otherwise would be a + promise this design cannot keep. + +Classification: + +- A deadline abort is `kind: 'timeout'` (already retryable, already mapped to `provider_unavailable` — the + same choice ADR-0045's poll deadline makes). +- A caller abort is `kind: 'cancelled'`. +- **Precedence when both fire in the same tick: the caller wins.** If the caller's signal is aborted at the + moment of classification, the failure is `cancelled` even if the deadline has also elapsed — the same + cancel-wins rule ADR-0036 uses. Without a stated rule the answer would depend on listener order, and the + test would pin a scheduler detail rather than a contract. +- Rule 7 governs both: a pre-content timeout may fail over; a content-committed one is surfaced with + `contentCommitted`. + +### 6. The timer port, the window, and the default + +- **Port.** The chain's existing `sleep(ms, signal)` and `now()` are not a disarmable one-shot timer. It gains + `newAbortController: () => AbortControllerLike` and a `setTimer(ms, fire) => disarm` alongside them — + host-injected for the same reason the others are: the seam is platform-free. +- **The window opens immediately before the seam call** — after `preAttempt`, after media re-materialization, + after credential resolution. Those are Relavium's own work and must not consume the provider's budget. +- **It is an ABSOLUTE per-attempt deadline, not an inactivity timeout.** Simpler to state, simpler to test, + and it is what bounds the caller's wait; a stall detector is a separate mechanism and is not decided here. +- **The default is `120_000` ms**, stated here rather than only in the seam doc — a default is part of the + decision, and an append-only ADR should not defer its own substance to a mutable document. Hosts override + it. A non-finite or non-positive value is a configuration error, refused at construction; **the timeout + cannot be disabled**, because "unbounded" is the state this ADR removes. +- **Against the caller's, the node's and the run's deadlines: whichever elapses first wins.** They compose by + earliest-expiry, and this one is the only one scoped to a single attempt. + +### 7. The terminal is buffered until EOF confirms it + +Rule 2 cannot be checked when the terminal arrives — only the NEXT read tells you it was last. And the chain +returns from the attempt the moment it sees an `error` chunk, so `error → text_delta` and `error → error` +would never be read at all. + +The verifier therefore **holds the terminal chunk, reads once more, and only then emits**: EOF confirms it and +it is forwarded; another chunk means a `protocol` failure is surfaced *instead of* the terminal. That +lookahead read is itself inside the attempt's deadline, so a provider that goes quiet after its terminal +cannot hang the verification. + +### 8. The verifier checks ORDER; runtime shape stays a separate obligation + +The verifier does not `StreamChunkSchema.parse` every chunk. It is a grammar check, and the seam's shape +obligation is stated separately and enforced by the conformance suite. + +That is a deliberate line, not an omission. Parsing every chunk of every token stream through Zod is a real +per-chunk cost — and unlike the ordering check, it is not a boolean branch, so the performance claim in the +Consequences below would stop being true. A foreign provider that emits a malformed chunk SHAPE is a bug the +conformance suite is there to find; a foreign provider that emits well-shaped chunks in an impossible order is +what silently becomes a wrong answer, and that is what this verifier is for. + +### 9. `protocol` gets its own `LlmErrorKind`, mapped to the existing `provider_unavailable` + +`protocol` is **not** in `RETRYABLE_KINDS`. A provider that cannot keep the grammar will not keep it on the +second call; retrying burns the node budget and reports the wrong cause. + +But a pre-content `protocol` failure should still advance to the NEXT entry — a different provider may be +well-behaved and the user has been shown nothing. Today the chain's `Verdict` is +`'fatal' | 'retryable' | 'auth-refreshed'`, and `retryable` first consumes the current entry's attempt budget +before advancing. That is the wrong shape for this: re-attempting the same broken provider is pointless. + +**So `Verdict` gains an arm: `'advance'` — go to the next entry without re-attempting this one.** `protocol` +pre-content resolves to `advance`; `protocol` content-committed is surfaced. + +No new `ErrorCode`. From a surface's standpoint a provider that cannot keep the stream grammar is not usable +for this request, and the remedy is what `provider_unavailable` already names. Widening a closed taxonomy that +every surface switches on, for a distinction no surface would act on differently, costs every one of them a +case and buys nothing. The load-bearing distinction — do not re-dispatch — is carried by `retryable: false`, +where the engine actually reads it. + +**One authoring consequence, called out so it is not discovered:** because `protocol` maps to +`provider_unavailable` with `retryable: false`, an authored `retry_on: [provider_unavailable]` +([ADR-0040](0040-node-retry-budget-above-the-chain.md)) does **not** make a grammar violation retryable. The +retryability gate runs first. + +### 10. Scope: `FallbackChain` attempts. `generateMedia()` submission is named, not silently included + +This ADR bounds every `generate`/`stream` attempt made through `FallbackChain`. The first +`generateMedia()` submission is currently awaited directly and unbounded — it is not a poll, so ADR-0045's +poll deadline does not cover it, and it is not a chain attempt, so this does not either. + +That gap is **named rather than absorbed**: bounding it needs the same treatment on a different call path, and +folding it in here would make the title claim more than the mechanism delivers. It becomes a tracked item on +the phase document with this ADR as its reference. + +### 11. What is NOT decided here + +- `CR-20`'s tool timeout and `CR-22`'s absolute resume deadlines are separate timers and stay separate. This + one bounds a single provider attempt; those bound a tool dispatch and a whole run. +- ADR-0045's media-job poll LOOP is untouched — its liveness is a poll interval against a provider-side job. +- `CR-23`'s never-settling node executor is a run-level liveness property with an open decision of its own. +- An inactivity/stall detector, as distinct from §6's absolute deadline. + +### 12. Acceptance + +Driven through fake providers, because the whole item is about not trusting the implementation. + +**The grammar** + +1. One test per row of §2's table, each with a fake provider producing exactly that observation. +2. A stream ending with no terminal produces a classified error and **no successful attempt record**. +3. An empty stream produces a classified `transport` error. +4. `error → text_delta` and `error → error` are detected — the cases the pre-lookahead chain could never see. +5. A pre-content `protocol` violation resolves to `advance`: the next entry is attempted, and the broken entry + is **not** re-attempted. Assert the attempt records, not just the outcome. +6. A content-committed violation does not fail over and produces no second attempt record. +7. `protocol` is absent from `RETRYABLE_KINDS`. + +**Rule 7's node-retry half — through the real engine, not a unit stub** + +8. A workflow node with `retry.max > 1` whose provider emits `text_delta` then `timeout` results in + **exactly one** provider call. The same for `transport`. This is the test whose absence let the defect + exist. +9. A PRE-content `timeout` with `retry.max > 1` **is** re-dispatched — the negative control, without which + test 8 passes for an implementation that disabled node retry entirely. + +**The deadline** + +10. A `generate()` that never settles and ignores its signal fails `timeout` within the deadline. +11. A stream iterator whose `next()` never settles does the same, and a provider that yields one chunk per + interval indefinitely still hits the ABSOLUTE deadline. +12. A caller abort in the same tick as the deadline classifies `cancelled`, asserted against the contract + rather than against fake-timer callback order. +13. Timer cleanup proven with a fake clock on every path, **including success**. +14. A late result arriving after a deadline abort produces no second attempt record and no cost update. + +**Money (ADR-0074)** + +15. An EOF-without-terminal and a deadline abort each produce exactly **one** failed attempt record. +16. With no trustworthy usage, the conservative commitment is **not** released — the same invariant the + current budget tests prove, re-asserted through a failed attempt instead of a spurious success. + +**The superseded tests** + +17. Tests resting on no-terminal-as-success are **rewritten, not deleted**, each carrying a note recording + the reasoning it replaces, the way `checkpointer.test.ts` was handled in Wave 1. The phase document's + "an existing test" is singular and wrong; the real set, verified against the tree: + + - `packages/llm/src/fallback-chain.test.ts` — done with the carrier. + - `packages/core/src/engine/agent-turn.test.ts` — done with the carrier. + - `packages/core/src/engine/m2-e2e-harness.e2e.test.ts` — **deferred to the wiring step, by design.** + It proves ADR-0074's conservative commitment survives a resume, using a no-terminal stream as its + usage-less attempt. Rewriting it before the verifier is wired would leave the money property untested + across the transition; rewritten WITH the wiring, §12.15-16's invariants are proven continuously. The + file carries this note in place. + - `apps/cli/src/commands/agent-run.test.ts` — **not actually affected.** Every scripted stream in it + already ends with an explicit `stop`. Listed here in error when this ADR was drafted; the count was + four and is three. + +**Performance** + +18. The per-chunk verifier cost is **measured** on a representative token stream, not asserted. + +### 13. Landing obligations + +Part of the change, not follow-ups: + +- ADR-0011: a dated amendment note for the grammar, the `protocol` kind and the `contentCommitted` field. +- [llm-provider-seam.md](../reference/shared-core/llm-provider-seam.md): the normative grammar, the + content-committed definition, the deadline contract and its default. +- [error-handling.md](../standards/error-handling.md): a `protocol` row in the `LlmErrorKind` table. +- The authoring note from §9 about `retry_on: [provider_unavailable]`. +- The seam doc's use of "terminal" for `media_end` clarified to "closes the media block", so it does not + collide with §1's stream terminal. +- The `generateMedia()` submission deadline (§10) filed as a tracked phase item. +- This ADR to Accepted, with the index row to match. + +## Consequences + +### Positive + +- The seam's obligation is stated and verified where it is crossed, so a cassette, a test double and Phase 2's + managed gateway are held to the same rule as an adapter we wrote. +- A truncated answer stops being reported as a complete one — the user-visible defect. +- The double-answer-double-charge path above the chain closes. Rule 7 gains its missing half. +- A hung provider can no longer hang a turn, whether or not it honours an abort. +- No vendor type crosses the seam, no new dependency, no new `ErrorCode`. + +### Negative + +- **The seam's error type and kind enum both grow.** Every exhaustive switch on `LlmErrorKind` must handle + `protocol`; the compiler finds them. The `contentCommitted` fold is one site that must not be forgotten, + which is why acceptance test 8 goes through the real engine. +- **`retryable` stops being the whole answer.** A reader must now know that commitment also gates retry. The + alternative — silently overriding `retryable` — hides the reason inside a boolean, which is worse. +- **The verifier and the lookahead sit on the hot path.** One branch and one held chunk per stream. Measured + rather than assumed (test 18); a boolean check is not where a streaming turn spends its time, but the claim + should be evidence. +- **A deadline can cut a legitimately slow attempt.** Hence a host-configurable default rather than a + compiled-in one. It cannot be disabled, which is a deliberate refusal: "unbounded" is the state being + removed, and a config flag restoring it would restore the defect. +- **Two layers detect a truncated first-party stream**, so a future change to one can leave the other wording + the same fault differently. Accepted: the redundancy is the trust boundary working, and the adapters' + messages are better attributed. +- **`generateMedia()` submission stays unbounded** until its own item lands.

Accepted 2026-08-19 after a review that rejected the first draft on five blockers; three of them changed a decision rather than a sentence, and each is answered in place (§3 templated defaults, §5 the authoritative reader and MCP augmentation, §6 what a secret ref can and cannot prove). The §11 obligations land with the implementation. + +## Context + +Two gaps that share one question: **what was this run admitted with?** + +### The authored input contract is validated by nobody + +`WorkflowInputSchema` carries `required`, `default`, `type` and a `validation` block — `format`, `pattern`, +`enum`, `min`, `max`, `min_length`, `max_length` — plus a per-type table of which keys are legal on which +type. Parse time enforces the AUTHORING rules (that `min <= max`, that a `*_length` is not put on a number). +It says nothing about the VALUES a caller supplies, and neither does anything else. + +`WorkflowEngine.start()` takes the caller's `inputs` object and hands it to the run execution, which stores +the reference without cloning, validating, or applying a single declared `default`. The CLI rejects unknown +keys, rejects a missing required input, and coerces argv strings — then defers: + +> `continue; // omitted — the engine applies the declared default, if any` + +The engine does not. A declared default arrives as `undefined`, an out-of-enum value reaches deep execution, +and every other surface gets whatever validation it happens to implement. + +### A resume trusts identity it never verifies + +`ResumeFromCheckpointInput`'s docblock states the gap and calls the remedy "a future revision": `workflow`, +`inputs`, `executionMode` and `planOptions` must be what the run started with, and nothing checks. + +**Most of the durable record already exists**, and this ADR is written from the tree rather than from the +phase document's assumption: + +- `runs.workflow_definition_snapshot` — *"the frozen graph that actually ran"*; `runs.input_json`; + `runs.execution_mode`. +- `run:started` carries `inputs` and `executionMode`, with every `secret`-typed input already masked to + `{ secret: true, ref: 'inputs.' }`. +- `relavium gate` **already** resumes from that snapshot and refuses a masked secret rather than substituting. + +So one host already does most of what `CR-17` asks. What is missing is that **the engine does not require +it** — a desktop, an extension or the Phase-2 API can resume the same run with different inputs and a +different mode, and nothing errors. + +### Three things in the tree that make the naive version of this ADR wrong + +A first draft was reviewed and rejected on these. They are stated here because each one changes a decision. + +1. **`inputs` defaults are a TEMPLATE field.** The spec lists them alongside `context` values and + `prompt_template` as places `{{ }}` interpolation is legal. "Validate the default at parse" is therefore + only expressible for a literal one. +2. **The frozen snapshot is NOT always what ran.** `relavium run` opens the history store with the parsed + definition, then augments the workflow with MCP-discovered tools, then starts the engine with the + augmented one. The snapshot is the pre-augmentation graph. +3. **The persisted secret `ref` is `inputs.` — a self-reference, not a credential identity.** It names + the slot; it says nothing about which key filled it. + +## Decision + +**We will add one pure admission gate in the engine that resolves and validates inputs before a run exists, +and make resume RECONSTRUCT its identity from the durable record rather than accept the caller's.** + +### 1. `resolveAndValidateWorkflowInputs` — pure, synchronous, in core, before anything exists + +A pure synchronous function in `packages/core`, taking the parsed workflow and the caller's raw inputs and +returning either the resolved input map or a typed admission error. It runs in `start()` **before the run id +is generated and before the first event is emitted**. + +That ordering is the decision. An admission failure must leave **no `runId`, no `run:started`, no row** — a +rejected run is not a run. + +**Synchronous, and §3 is what makes that possible.** An async admission would need a cancellation contract, +an ordering rule against the lease, and a story for a host capability failing mid-admission. None of that is +worth carrying for a step whose whole job is to say yes or no to a map. + +### 2. The surface coerces; the engine is strict + +- **A surface may COERCE** — turn its transport's representation into the declared type. A CLI has only + strings, so `--input count=3` must become the number `3` somewhere, and only the surface knows its + transport. +- **The engine is STRICT.** Given a `number`-typed input it accepts a number, not `"3"`. It applies defaults, + checks `required`, rejects unknown keys, and enforces every `validation` field. + +Considered and rejected: coercing in the engine (it would silently accept a form's stringly-typed payload as +validated, and bury each surface's quirks in shared code); validating only at the surface (the status quo). + +### 3. Interpolation is FORBIDDEN in an input `default` + +The spec today lists `inputs` defaults as a template field. This removes them from that list, and the reason +is that at admission time — which must precede run creation — **none of the three referenceable scopes +exists**: + +- `{{inputs.*}}` is what admission is resolving. A default referencing another input needs a dependency + order, cycle detection and a dangling-reference rule, for a feature nothing uses. +- `{{ctx.*}}` is resolved at RUN START, after admission by construction. +- `{{secrets.*}}` must never enter a default at all (§6). + +**No run behaviour changes, but this is not a no-op — and the difference is worth stating precisely.** The +engine never applied a declared default, so a templated default's VALUE is dead today: it parses, and it +never reaches a run. What is NOT dead is the ANALYSIS of those templates. `analyzeSecretTaint` treats an +input default as a live reference site and rejects `default: '{{secrets.token}}'` laundered into a +`prompt_template` — transitively, across multiple hops — and `analyzePreRunReferences` flags a default +reading `run.outputs`. + +Forbidding interpolation **subsumes** those rules rather than orphaning them: a default that cannot reference +anything cannot launder a secret, and the rejection moves one step earlier, from "this reference leaks" to +"this field takes no references". The security outcome is strictly stronger — an attack surface disappears +instead of being policed — and the tests that proved the old rule are rewritten to prove the new one, with +their reasoning recorded. + +What a workflow author loses is a feature whose value never arrived. That is +[ADR-0023](0023-strict-authored-yaml-validation.md)'s own rule: silent deadness becomes a loud authoring +error. + +With interpolation gone, a `default` is a literal, and **an authored default that violates its own +`validation` block fails at PARSE** — not at run, where it would surface only the first time someone omits +that input. + +Considered and rejected: **two-phase validation** (literal defaults at parse, templated ones at admission). +It preserves a feature that has never worked, at the cost of dependency ordering, cycle detection, async +capability access inside a step this ADR deliberately keeps synchronous, and a second place validation lives. + +### 4. Validation semantics, decided rather than implied + +The current schema types `format` and `pattern` as any non-empty string, `enum` as `unknown[]`, and `default` +as `unknown`. "Enforce every validation field" is not implementable against that, so: + +- **`format` is a CLOSED vocabulary**: `email`, `uri`, `uuid`, `date-time`. An unrecognised format is an + authored error at PARSE. An open vocabulary would mean each surface inventing its own semantics — the + failure this whole ADR is about. +- **`pattern` is compiled at PARSE**, so an invalid regex is an authored error rather than a run-time throw. + It is **anchored** (a full match, not a search) and carries **no flags** — "does this value match" is the + only question the field can honestly answer across surfaces. Its source is length-capped. +- **ReDoS is bounded, not eliminated.** A pattern is matched only AFTER the length checks, so `max_length` + bounds the input a catastrophic pattern can chew on. An author who writes a nested-quantifier pattern and + no `max_length` can still stall their own run; that is named here rather than papered over, and the + mitigation is the length cap, not a static analysis we would get wrong. +- **`enum` members must satisfy the declared `type`** at parse. Matching is `Object.is`, so `NaN` matches + `NaN` and `0` does not match `-0` — a decision, because `===` and deep equality both answer differently. +- **A `number` must be finite.** `NaN` and `±Infinity` are rejected regardless of `min`/`max`, which cannot + express them. +- **Absent means absent.** A missing key and an own property whose value is `undefined` are both "omitted" + and take the default. **`null` is a VALUE**, not an omission, and fails type validation for every declared + type. +- **`required: true` with a `default` is satisfied by the default.** That is what the CLI already assumes. + +> Amended 2026-08-19 — three corrections the implementation forced, each measured before it was written. +> +> - **An anchored `pattern` must be a complete regex on its own.** "Anchored" above assumed the wrapping +> group defends itself. It does not: a source carrying an unmatched `)` closes it early, so `x)|(?:.*` +> anchors to `^(?:x)|(?:.*)$` — a declared `pattern` that matches EVERY string while this ADR promises a +> full match. Rejected at parse, by compiling the source BARE: escaping the wrapper requires a `)` that is +> unmatched within the source, which is a `SyntaxError` bare in every mode. The check is the regex engine's +> own, not a parenthesis scanner we would get wrong. +> - **`format: uri` means any absolute URI.** The first implementation required `://`, so it rejected +> `mailto:`, `urn:` and `data:` — URIs by every definition of the word, under a vocabulary key that says +> `uri` and not `url`. Corrected to a scheme-prefixed absolute URI. +> - **A `date-time` is range-checked per component, and no string format admits a control character.** +> Unbounded two-digit groups accepted `0000-99-99T99:99:99Z`, which is not a pragmatic check failing +> gracefully but the check being absent. Calendar validity — `2026-02-31` — is still out of scope and now +> says so. The control-character exclusion is because these values are echoed by surfaces and written to +> log sinks, the same reason §1's issue messages are value-free. + +### 5. Resume reconstructs identity; the caller's copy is VERIFIED, not trusted + +**Authority, named once.** `inputs` and `executionMode` come from **`run:started`**, folded into +`CheckpointState` — the ordered durable log is the truth ADR-0078 built, and the engine already folds that +event. No new port. The engine does **not** read `runs.input_json`, so there is no two-source disagreement to +resolve. + +**The graph comes from the frozen definition**, which lives in `runs` and is not in the event log. `RunStore` +gains **one method** to read it — a method on the seam the engine already owns, not a new port. Verification +is a **deep structural equality** against the caller's parsed workflow, on the normalized parse output rather +than raw YAML, so formatting and key order cannot cause a false mismatch. That answers +[ADR-0079](0079-cross-process-run-ownership-lease-and-fencing-token.md) §4's deferred content hash without a +digest and without asking a platform-free engine to compute SHA-256. + +**The snapshot must be the ADMITTED definition** — §Context 2's bug. `relavium run` currently freezes the +pre-augmentation graph and starts the engine with the MCP-augmented one, so the two differ on every run with +`mcp_servers`. The host must persist what it started the engine with. **MCP-discovered tool grants are part +of workflow identity**: they are part of the graph that ran, and an MCP server returning a different tool set +on resume IS a divergence. It fails closed, and the error says so rather than continuing under a graph the +run never had. + +**A refusal releases the lease.** Every identity check sits after `resumeFromCheckpoint` has acquired +ownership, and [ADR-0079](0079-cross-process-run-ownership-lease-and-fencing-token.md) §4's rule — an acquire +that leads nowhere must not leak — covers these exactly as it covers `workflow_mismatch`. + +**`planOptions.agents` is verified by ID, not by content**, because the resolved agents are read from the +filesystem by the host and are not persisted.

The verified-by-ID limitation above is unchanged; what is dropped +> is a second name for it. + +### 6. A `secret` input: what the engine can prove, and what it cannot + +A `secret` value is never persisted; the record carries `{ secret: true, ref: 'inputs.' }`. + +**The contract:** the caller re-supplies the secret by name; a missing or unexpected secret is a typed error; +it is never silently substituted, defaulted, or dropped to `undefined`. The CLI's existing +`assertNoMaskedSecretInputs` already takes the refusing side; the engine adopts it as the contract. + +**What that proves, stated exactly.** The engine verifies the SLOT — that the same named secret input is +supplied, and that the record holds a masked placeholder rather than a value. It does **not** prove the value +is the same credential, that nothing was rotated, or that the run continues under the key it started with. +The persisted ref is a self-reference; it names the slot, not the key. A first draft of this ADR claimed +"same inputs" and "a different credential is prevented"; both are withdrawn. + +Considered and rejected: **failing closed on any secret-bearing resume** until a versioned reference exists +(it would break every secret-bearing `relavium gate` today, to buy a guarantee nothing can yet check); +**inventing a key version here** (there is no key-versioning concept in the tree; a second unused mechanism +is worse than a named gap). + +**A `secret` input may not declare a `default`.** It can today, and such a default is written verbatim into +`runs.workflow_definition_snapshot` — a plaintext credential in the durable store. Rejected at PARSE, and +§9's acceptance scans every persisted column, not just the input map. + +> Amended 2026-08-19 — **a `secret` also loses `enum`.** The rule shipped with the parse-time half and this +> section did not carry it, which left the code citing a paragraph that said nothing and the canonical +> [spec table](../reference/contracts/workflow-yaml-spec.md) contradicting the shipped parser. It is the +> same reasoning as the `default` ban one paragraph up: an `enum` of allowed secret values writes the +> credential into the same unmasked `workflow_definition_snapshot` column through a neighbouring key, and +> "the credential is one of these three" is not a contract worth expressing. `pattern` survives, because a +> SHAPE is not a value — and an author who writes a literal there has written the secret down either way. + +**That closes the DECLARED case and no more, which is worth saying plainly.** The snapshot is the full +authored YAML, unredacted — [phase 2.5.5](../roadmap/phases/phase-2.5.5-hardening-and-remediation.md) already +records this and names the residue: a hardcoded credential literal sitting in an unrelated field is not a +declared `secret`, so no taint rule and no rule here sees it. Its own item — a best-effort secret-shaped- +literal lint at authoring time — stays where it is. This ADR removes one path into that column; it does not +make the column safe. + +**Re-supply must not travel through argv.** A raw secret on a command line leaks to `ps`, shell history and +CI logs; `relavium provider set-key` already uses stdin for exactly this reason. The CLI's secret-bearing +resume takes its value the same way, and `relavium gate` gains that option — it has none today. + +### 7. The engine BUILDS its input map; it does not clone the caller's + +The resolved map is constructed fresh, with a `null` prototype, by iterating the DECLARED inputs and reading +the caller's object through `Object.hasOwn`. The caller's object is never spread, assigned from, or cloned +wholesale. + +**A first draft said `structuredClone`, for a reason that was wrong twice.** `JSON.parse` makes `__proto__` an +own property and does not pollute; and `structuredClone` does **not** preserve a null prototype — it returns +an ordinary object. Both were verified. The real hazard is the ACCUMULATOR: writing `out[name] = value` onto a +`{}` when `name` is `__proto__` invokes the prototype setter, and an input name may legitimately be +`__proto__` under the `[A-Za-z0-9_-]+` grammar. Building a null-prototype map from the declared list closes +that at both ends, and it also gives the "unknown key" check for free. + +Mutating the caller's object after `start()` cannot change the run, because the run never holds it. + +### 8. `start` and `resume` apply the SAME admission + +Both go through §1. A resumed run's inputs are the durable ones, so admission is re-verification rather than +re-resolution — but running the same function means a rule cannot hold on one path and not the other. + +**A legacy run keeps its own semantics.** A run admitted before this landed may have no recorded value for an +input that declares a default. Resume VERIFIES what is recorded; it does not invent a value the run never +had. That follows from §5's authority rule and needs no version marker. + +### 9. Acceptance + +1. A missing `required` input fails admission; one satisfied by a `default` does not. +2. An unknown input key fails admission. +3. **Every** `validation` field rejects a violating value and accepts a conforming one — one case each, both + directions — plus: an unknown `format`, an invalid `pattern`, and an `enum` member of the wrong type each + fail at PARSE. +4. A `pattern` is anchored: a value that merely CONTAINS a match is rejected. +5. `null` fails; a missing key and an own `undefined` both take the default; a non-finite number fails. +6. The engine is strict: a `number`-typed input rejects `"3"`. The CLI's coercion of `"3"` into `3` before + the engine is pinned separately, so the split is proven from both sides. +7. Input names `__proto__`, `constructor` and `toString` round-trip as ordinary inputs, on the CLI path and + the engine path, with `Object.prototype` unpolluted after. +8. Interpolation in a `default` fails at PARSE, with the message naming the rule. +9. An admission failure produces a typed error and **no `runId`, no `run:started`, an untouched store** — + asserted by inspecting the store. +10. `start` and `resume` reject the same violating input. +11. A resume whose caller passes different inputs, a different `executionMode`, or a content-different + workflow is a typed error — one test per axis, each asserting the run did not continue **and that the + lease was released**. +12. An **MCP-augmented** workflow resumes cleanly when the server returns the same tools, and fails closed + when it returns a different set. +13. A resume that omits a required `secret` is a typed error; one that supplies it proceeds; the persisted + record still contains only the ref. +14. A `secret` input declaring a `default` fails at PARSE, and a scan of **every persisted column** — + including `workflow_definition_snapshot` — finds no raw secret. +15. A **pre-0083 legacy fixture**: a durable record missing a key that now declares a default resumes with + what it recorded, and the default is not invented. +16. **No assertion that a secret's VALUE round-trips** — proving that would require persisting it. + +### 10.

Opening that +artifact runs the command. + +Not "may eventually run it once a tool call is approved" — runs it, while the session or run is being +*constructed*, before the first turn exists. `connectAgentMcp` / `connectWorkflowMcp` resolve each declared +server into an `McpServerConfig` whose `open()` hands the spec to `openStdioConnection`, which constructs a +`StdioClientTransport` and spawns the child. The manager then calls `tools/list`, because the agent's tool +grant is *derived from what the server reports* — so the spawn is neither optional nor deferrable (§8). + +Four properties, each measured against the tree rather than assumed: + +- **The per-tool approval gate cannot see it.** [ADR-0057](0057-cli-chat-modes-and-per-tool-approval.md)'s + `confirmDispatch` runs inside the tool registry, at dispatch. The spawn is strictly earlier. `ask` mode — + the mode whose entire promise is "nothing happens without me" — does not cover it, and neither does `plan`. +- **`shell: false` is not a defence.** It stops a shell from interpreting a string. It does not stop the + declaration from naming `sh`, `bash`, `node` or `npx` as the executable, and it does not stop a bare command + from resolving through the child's `PATH` — measured: with `PATH` prefixed to a temp directory, the SDK's own + `cross-spawn` ran a planted `npx`. +- **The declaration is the only gate today.** Registering — or inline-declaring — a stdio server *is* what + authorizes the spawn. There is no second one. And an agent may declare a fully inline server with no + `[[mcp_servers]]` registration at all, which is exactly the imported-artifact case. +- **The artifact is often not the user's.** `relavium import` exists to bring in a workflow someone else + wrote. The threat is the ordinary act of trying out a shared artifact. + +The network transports already have a floor: [ADR-0053](0053-mcp-network-transport-egress-security.md) puts +every `http`/`sse`/`websocket` URL through an SSRF check before it is reached. The *local* transport — the one +that executes code on the user's machine — has none. + +### The child env is an unrestricted override channel, and a sibling host already knows it + +[ADR-0034](0034-mcp-client-sdk-dependency.md) g5 describes the spawned child's environment as "the declared +env + a minimal base, never a blanket copy". True, and incomplete in the direction that matters: the SDK +spawns with `{ ...getDefaultEnvironment(), ...spec.env }`, so **the declared env wins every conflict**, +including over the base's own `PATH`. `buildChildEnv` inspects no key name; it resolves `{{secrets.*}}` +placeholders and passes everything else through verbatim. + +Measured, on this tree's pinned SDK: `NODE_OPTIONS: '--require /tmp/preload.js'` executed the preload before +the target script; a prefixed `PATH` redirected a bare `npx`; `DYLD_INSERT_LIBRARIES` was honoured for a +non-SIP binary (and stripped for a SIP-protected one); `LD_PRELOAD` passes through intact and is the live arm +on Linux. + +The project already draws this line one module away: `run_command`'s host maintains a denylist of declared +environment names covering interpreter and loader option injection, the whole `GIT_` namespace, and +config-home redirection. The MCP stdio path being exempt from the identical rule is a gap, not a decision — +§4 closes it. + +### Three corrections this ADR is built on, verified against the tree + +The plan review of [phase 2.6.5](../roadmap/phases/phase-2.6.5-core-reliability-remediation.md) checked the +original `CR-16` item against the code and found three of its assumptions wrong. + +1. **Lazy connect is structurally blocked**, so it is not part of this ADR (§8). +2. **`cwd` is host-supplied, not authored.** `McpServerRefSchema` is `.strict()` and has no `cwd` field; the + value comes from `deps.global.cwd`. §3 records what that does and does not imply. +3. **`relavium import` spawns nothing.** It is synchronous YAML I/O. The execution happens at the next + `chat --agent` / `agent run` / `run`, which is where the gate belongs (§9). + +## Decision + +**A stdio MCP server is not spawned until the user has consented to that exact declaration, resolved to an +exact executable, in that exact directory — and the consent is remembered by fingerprint.** In a +non-interactive process there is no prompt: a run with no recorded consent and no explicit authorization is +refused, with the digest printed so it can be authorized deliberately. + +### 1. The gate is a HOST decision, at one chokepoint, before any spawn — and it covers the CLI + +`@relavium/mcp` stays a transport fence: it knows how to spawn and connect, and nothing about who is allowed +to. The gate lives in the CLI host, in `apps/cli/src/engine/mcp-servers.ts`, between resolving each declared +server to its **inline** form and building the `McpServerConfig`s — the single point both `connectAgentMcp` +(chat, agent run) and `connectWorkflowMcp` (workflow run) already pass through. Gating on the *resolved inline +ref* rather than on a registration is what makes it cover an agent that declares a server with no +`[[mcp_servers]]` entry, which is the imported-artifact case. A refused server means `open()` is never +constructed, let alone called. + +**Scope, stated rather than implied.** This gate covers the Node/CLI surface, which is the only surface that +can reach a stdio spawn today — `apps/desktop` and `apps/vscode-extension` contain a README and nothing else. +[ADR-0052](0052-inbound-mcp-client-package-lifecycle-registration.md) §1 assigns the desktop's stdio lifecycle +to its **Rust backend**, which never imports `@relavium/mcp`, so a gate in `apps/cli` is structurally +incapable of covering it. **A Phase-3 desktop or VS Code surface must implement its own gate before it ships a +stdio spawn**, and §3's digest plus §5's grant file are defined as a **language-agnostic contract** precisely +so a second implementation satisfies the same rule rather than inventing a parallel one. +[ipc-contract.md](../reference/contracts/ipc-contract.md) is the existing precedent for a contract the Rust +backend must satisfy, and §11 lands the invariant there. + +Considered and rejected: **a consent hook inside `@relavium/mcp`** (policy and a prompt contract inside the +SDK-fenced package, which has no business owning either); **reusing +[ADR-0057](0057-cli-chat-modes-and-per-tool-approval.md)'s `ConfirmActionHook`** (a *dispatch*-time hook over +a `ToolDef`, and there is no tool yet — the tools are what the spawn discovers); **gating inside each `open()` +thunk** (correct but later — "nothing was spawned" would become a property of every adapter rather than of one +decision). + +**Proven by counting spawns, not by reading a flag.** §10's acceptance injects a counter at the process +boundary and asserts zero. + +### 2. Consent is per server, not per artifact + +Each declared server gets its own decision, showing its own executable. A batched "this artifact will run 2 +programs — approve all?" is rejected: the most dangerous line disappears into a list, and "approve all" is the +habit that empties consent of meaning. The *count* is stated once before the first prompt ("this artifact will +start 2 local programs"), so a user knows how many decisions they are entering rather than discovering the +second one after granting the first. + +A refused server fails the whole start, which is +[ADR-0052](0052-inbound-mcp-client-package-lifecycle-registration.md) §2's existing fail-loud rule — a run +that silently lost a tool grant would be worse than one that stopped. + +### 3. The fingerprint: what makes it "the same server I approved" + +```text +v1:<64 lowercase hex> = "v1:" + sha256( canonicalJson({ + transport : "stdio", + command : , + args : [], + env : { : { kind: "literal", value: } + | { kind: "secret-ref", name: }, … }, + cwd : , +}) ) +``` + +**The command is RESOLVED before the gate, and the resolved path is what is spawned.** A digest over the word +`npx` names a word, not a program: the ambient `PATH` decides which file runs, and a directory prepended to it +substitutes another binary under an unchanged declaration. So the host resolves `command` against the ambient +`PATH` (and `PATHEXT` on Windows) *before* computing the fingerprint, digests the absolute path it found, and +passes **that same absolute path** to the spawn. A command that does not resolve is refused before any prompt +— an unresolvable executable is not a decision a user can meaningfully make. (An earlier draft claimed the +child's `PATH` was "now in the digest" and closed this. It did not, and could not: §4 forbids an authored +`PATH` outright, and the *inherited* `PATH` was never in the payload.) + +**Env values are IN, type-tagged, and an earlier draft's reason for excluding them was measured false.** That +draft said hashing the authored placeholder "would make the fingerprint change when a secret is rotated". It +would not: `{{secrets.foo}}` is literal authored text, and rotating the keychain entry changes what the +resolver returns at spawn time, never the text. Excluding values bought nothing and cost the whole guarantee — +`NODE_OPTIONS` is an env *name*, so a grant taken for one value matched any later value byte for byte. + +Each value enters under an explicit `kind`, and the tag is load-bearing rather than decorative: a flat +`secret:` marker collided with the *literal string* `secret:`, so an approved literal could later +become a real credential reference with no re-prompt. The split follows the project's other durable digest, +where a secret-tainted value is **removed** before hashing rather than hashed, because a digest over an +unencrypted-at-rest store is a permanent offline oracle: + +- A value that is exactly one `{{secrets.}}` reference contributes `{ kind: "secret-ref", name }`. The + credential never enters the digest, and swapping `{{secrets.a}}` for `{{secrets.b}}` — handing the same + approved program a *different* credential under an unchanged set of env names — re-prompts. +- Any other authored value contributes `{ kind: "literal", value }` with the text as written. If an author + hardcoded a literal credential there, its digest is derived — named rather than hidden: the same literal is + already sitting in plaintext in the artifact and, for a registration, in `config.toml`, so the digest adds + no exposure the machine did not have. The + [phase 2.5.5](../roadmap/phases/phase-2.5.5-hardening-and-remediation.md) secret-shaped-literal lint is the + item that addresses hardcoded credentials; this ADR does not. + +**`cwd` is IN, as a canonical realpath.** An earlier draft left it out for consent-fatigue reasons, on the +premise that a fingerprint identifies "that specific executable". It does not, without `cwd`: +`McpServerRefSchema` does not require an absolute path, and an argument like `server.js` resolves against the +spawn directory — measured, one identical declaration is two different programs in two directories. A grant is +therefore **project-scoped**. The path is `realpath`'d so two symlinked routes to one directory are one grant +rather than two, and so a symlink swapped between grant and spawn cannot present as the approved directory. +The fatigue cost is real and accepted, mitigated by telling the user what the prompt is a repeat of ("you +approved this same program in `~/a`") rather than by weakening the identity. + +**What the digest still does not pin, said plainly.** It names a *file at a path*, not that file's contents: +between the grant and a later spawn the bytes at that path can change, and `npx -y @acme/server` resolves a +*package* at run time to whatever the registry serves. No digest available here closes either, and the +alternatives are worse — **hashing the artifact file** is defeated by `relavium import` re-serializing through +`serializeAuthored`, so the on-disk bytes differ from the reviewed bytes; **hashing the executable's contents** +would re-prompt on every routine upgrade of a trusted tool while still not covering an interpreter reading a +changed script. + +**Canonicalization is byte-exact, because a digest is a stored equality oracle a second implementation must +reproduce.** It follows the repo's existing `canonicalJson` / `digestOf` +(`packages/db/src/effect-journal-store.ts`) rather than inventing a second canonicalizer: object keys sorted +by **UTF-16 code-unit ordinal** comparison (never `localeCompare` — the nearby `mcp-servers.ts` sort uses it +today and is a latent reproducibility defect this ADR does not inherit), no whitespace, UTF-8, SHA-256, +**lowercase hex**. Five things that helper does not settle are pinned here: + +- an **absent** `args` or `env` serializes as `[]` / `{}` — absent and empty are the same declaration; +- string escaping is **ECMAScript `JSON.stringify` semantics** (`\"`, `\\`, `\b\f\n\r\t`, `\uXXXX` for other + C0, everything else literal UTF-8), because that is what the existing helper produces and what a second + implementation must match rather than guess; +- a **lone surrogate** in any field makes the declaration unfingerprintable and is refused at parse — it has + no well-defined UTF-8 encoding, so two implementations would legitimately disagree; +- the digest carries a **`v1:` algorithm prefix**, so changing any of the above later makes every stored grant + unrecognisable and fails closed into a re-prompt rather than silently matching; +- a set of **golden test vectors** (declaration → digest) ships with the contract, covering non-ASCII, an + embedded quote and backslash, an empty `args`, and an absent `env`, so a Rust implementation is verified + against the same fixtures rather than against a second reading of this paragraph. + +`node:crypto` computes it, host-side — the CLI is a Node surface, `packages/core`'s purity is untouched, and +[CLAUDE.md](../../CLAUDE.md) rule 3 forbids hand-rolling it. + +### 4. One environment denylist, shared by both process hosts + +A declared MCP stdio `env` is subject to **the same forbidden-name rule `run_command` already enforces** — +interpreter and loader option injection, module paths, the `GIT_` namespace, config-home redirection, and +`PATH` — matched **case-insensitively**. Rejected at parse, as an authored error. + +**The list is not restated here.** An earlier draft named four entries and called them "the exact list"; +they were a subset, and a subset is worse than a citation because it reads as complete. The rule becomes one +exported predicate in `@relavium/shared` — the package both the agent schema and the config schema already +parse through — consumed by `run_command`'s host and by the MCP path, with a test asserting the two cannot +drift apart. **That predicate is the list's one canonical home**; today the names live only inside +`process.ts`, and [security-review.md](../standards/security-review.md) §Sandbox and tool policy states the +rule without enumerating them, which is why §11 extends that section to cover the MCP path rather than +copying a list into a second place. + +Consent answers "do I trust this program"; a loader variable answers "this is actually a different program", +and the two are not the same question. The fingerprint alone would catch a *change*, but an approved server +could still be handed `NODE_OPTIONS` on the very first run. One rule, one list, both hosts. + +This is a **compatibility break**: a workflow that declares `env: { PATH: … }` parses today and stops parsing. +It is taken deliberately — the alternative is a documented inconsistency where the same variable is dangerous +in one host and inert in the other — and §11 lands it in both the agent and the config spec. + +### 5. The grant store: an append-only log, machine-local + +`~/.relavium/mcp-consent.ndjson`, mode `0600`, inside the existing `0700` directory. + +**A file rather than a `history.db` table**, because a trust decision is not run history: putting it there +needs a migration and widens that database from "what the runs did" to "what this machine believes". **Not a +config layer**, because the project and workspace layers are git-committable by design — a grant recorded +there would travel to every other machine — and the global layer is deliberately write-restricted to a few +typed preference keys. + +**Append-only with tombstones.** The repo's terminal outbox began as a rewrite-in-place file and was changed +to append-only *because* a read-modify-write lost data across concurrent `relavium` processes, which are a +supported scenario. A consent store has the identical shape, so it takes the identical protocol: one JSON +object per line, a later `revoked` line tombstoning an earlier grant, and the effective set computed by +folding the file. + +**The write protocol is append, not replace — and an earlier draft contradicted itself here.** It specified +both "append-only" and a temp-file + atomic `rename`, which are incompatible: a rename replaces the whole +file, discarding whatever a concurrent process appended in between, which is precisely the guarantee +append-only exists to provide. So: + +- **Creation** is `openSync(path, 'wx', 0o600)` — create-if-absent, owner-only from the first byte, never a + `chmod` after create, which the project has already been bitten by on `history.db`. Losing that race is + fine: the winner's empty file is the file, and the loser proceeds to append. +- **Every write** is a single `appendFileSync` of one bounded record, framed with a leading newline and + serialized through the safe line serializer — byte-for-byte the outbox's own protocol, so a torn write + cannot merge with the next record and a partial line is recognisable as partial. +- The permission is **self-healed on every touch**, as the outbox does, so a file restored from a backup with + a wider mode is repaired rather than trusted. + +**Any unparseable line makes the whole store "no grants" for that invocation, and is reported.** Skipping the +bad line and keeping the rest is the tempting answer and the wrong one: a truncated line may be a *tombstone*, +and dropping it silently resurrects a grant the user revoked. Failing the whole fold closed costs one prompt +and cannot re-authorize anything. + +No lock is taken; concurrent appends of the same grant are idempotent by digest. + +### 6. Non-interactive: a recorded grant is enough; otherwise, the digest on the command line + +- A **recorded grant** for the fingerprint satisfies the gate. Consent means "I trust this program on this + machine, in this project"; requiring it to be re-proven every run would empty it of meaning and would make + the interactive and `--json` invocations of the same command behave differently for no security gain. +- Otherwise the run is **refused, exit 2**, and the message names the executable and prints the `v1:` digest so + a CI author can authorize it with `--allow-mcp-stdio ` (repeatable). An ephemeral runner has an empty + store by construction, which is the case the flag exists for. **The digest is not a secret** — it is a hash + of an approved declaration, safe in a CI definition, a script, or a log. + +`--allow-mcp-stdio` authorizes for **that invocation only** and writes nothing: a flag is how a CI definition +states its own trust, and a runner that silently accumulated grants would be a shared machine slowly agreeing +to everything anyone ran on it. + +**A prompt requires all four of: stdin a TTY, stdout a TTY, no `--json`, not CI.** Stdin alone is not enough — +a piped stdout or `--json` would put a question into a machine-readable stream, breaking +[ADR-0049](0049-cli-machine-output-contract.md)'s contract, and `CI=true` with an attached TTY would hang +an automated job on a question nobody answers. Any of the four failing means refuse-with-digest, not ask. The +prompt itself lives in one wrapper module behind an injectable seam, per +[ADR-0047](0047-cli-framework-commander-ink-clack.md), and defaults to **No**. + +### 7. A changed fingerprint re-prompts, and the prompt shows what is being decided + +A grant is for one exact `(resolved command, args, env, cwd)`. A difference in any of them is a different +declaration and is prompted again — with the *difference* named from the stored comparison metadata, because +"the args changed" is the fact the user needs and "here are two hashes" is not. + +**The prompt shows the whole decision, not a summary of it.** A user cannot consent to "the exact +declaration" while half of it is invisible, and the env is exactly the half that changes what an executable +does. Displayed, each as its **own field** — never a joined shell string, because argument boundaries are +precisely what an escape sequence or a bidi override would blur: + +- the server **id**, and its provenance: an inline declaration or the `[[mcp_servers]]` registration name; +- the **artifact** the declaration came from (the workflow/agent path), so the imported-artifact case names + its own file; +- the **resolved executable path**, and the authored `command` beside it when the two differ (`npx` → + `/opt/homebrew/bin/npx`); +- each **argument**, one per line; +- each **env name with its authored value** — `` for a reference, and the sanitized, bounded + authored text for a literal. A resolved secret is never displayed, and a `kind` is never inferred from how + the text looks; +- the **realpath'd cwd**. + +Every one of those fields is artifact- or path-derived, and a consent prompt showing a different command than +the one that will run is precisely the attack [security-review.md](../standards/security-review.md) names. +Each renders through the CLI's existing terminal-control sanitizer — which already neutralises CSI, OSC, DCS, +C0/C1 and the full Trojan-Source bidi family — extended to strip **zero-width** characters for these fields, +because an executable name in a trust decision is a structured field exactly like the URL the provider surface +already rejects them from. Any consent output under `--json` goes through the safe line serializer. + +### 8. What is NOT decided here: lazy connect + +The original item asked for the spawn to be deferred to "the first actual MCP tool need". That is structurally +blocked, and is split out with its blocker named rather than quietly dropped. + +An MCP `ToolDef` exists only because `listTools()` ran at connect. `createToolRegistry` returns +`{ has, list, dispatch }` with its tool map captured at construction and no mutation API — a deliberate +[ADR-0052](0052-inbound-mcp-client-package-lifecycle-registration.md) §3 invariant. Deferring the spawn +therefore *deletes* the agent's MCP tool grant, and there is no "first actual tool need" to trigger a connect, +because the model was never told the tools exist. The unblocker is a persisted tool-list cache, itself +deferred. + +Adding a registry mutation API would **reverse** ADR-0052 §3 and needs a supersession — it must not happen +inside an implementation PR. **Consent-before-spawn alone satisfies the whole of the original item's +acceptance**, and it is the security-relevant half: lazy connect would reduce how *often* an approved program +runs; consent decides *whether* it runs. + +### 9. `relavium import` is untouched + +It spawns nothing. Gating it would be theatre — the user would approve at import and the program would run +later anyway, at the `chat` / `agent run` / `run` that actually opens the artifact, which is where the gate is. + +### 10. Acceptance + +1. Opening an artifact with an unapproved stdio server **spawns nothing** — proven with a spawn counter + injected at the process boundary and asserted at zero, not by inspecting a state flag. +2. Approving it spawns exactly once and the run proceeds; declining refuses the run (exit 2) and still spawns + nothing. +3. A second invocation **in the same directory** with a recorded grant does not prompt, and spawns. +4. Each of a changed `command`, a changed `args`, a changed env **name**, a changed env **value**, a + `{{secrets.a}}` → `{{secrets.b}}` swap, and a changed `cwd` re-prompts. A **rotated keychain secret behind + an unchanged reference does not.** +5. **A literal env value `secret:prod` and a `{{secrets.prod}}` reference produce DIFFERENT digests** — the + type-tag collision, asserted directly. +6. The digest is computed over the **resolved** executable: two different binaries reachable as the same bare + `command` under two different ambient `PATH`s produce different digests, and the spawn receives the + resolved absolute path — asserted by planting a binary and observing which one ran. +7. Two symlinked routes to one directory are **one** grant; a symlink repointed between grant and spawn does + **not** match. +8. A declared `env` naming any denylisted key fails at PARSE (exit 2) — asserted for an inline `mcp_servers` + entry and a `[[mcp_servers]]` registration, case-insensitively, plus a **drift test** proving both process + hosts consume one predicate. +9. Non-interactive with no grant: exit 2, nothing spawned, and the printed digest is exactly the one + `--allow-mcp-stdio` accepts — asserted by feeding the printed value back in. +10. **No prompt** when any of stdin-TTY, stdout-TTY, `--json`, CI fails — including the case where **both** + streams are TTYs and `--json` is set. +11. `--allow-mcp-stdio` authorizes that invocation and writes **no** grant — asserted by reading the store. +12. The store is created `0600` **at open** (asserted on a pre-existing wider-mode file, which is repaired), + inside a `0700` directory, and contains **no env value and no resolved secret** — asserted by scanning the + written bytes for a seeded credential. +13. **Two real concurrent child processes**, each granting a different server, both survive — asserted by + folding the file afterwards. Run as actual processes, not as two calls in one process, because that is the + race the protocol exists for. +14. **A grant followed by a TRUNCATED tombstone spawns nothing** — the whole store folds to no-grants and the + invocation re-prompts or refuses. A corrupt line is reported. +15. The digest is **stable across runs and processes**, matches the shipped **golden vectors**, and a + `v1:`-prefixed grant is unrecognised by a `v2:` reader (fails closed). A declaration containing a lone + surrogate is refused at parse. +16. Every displayed field survives a hostile declaration — CSI, OSC 8, U+202E, zero-width — with the rendered + text carrying none of them, asserted on the prompt composition and not on an error boundary; and the + arguments render as separate fields, asserted by an argument containing a space. +17.

Both share the retryable-code set, the attempt budget, the linear schedule and the fail-loud exhaustion; only the sleep differs. Read the scope precisely: this removes the **sub-300 ms** term of the ~25 s worst case above, not the dominant one — for `SQLITE_BUSY`/`SQLITE_LOCKED`, the codes that actually fire, each attempt still blocks inside the synchronous driver for up to `busy_timeout` (~5.2 s measured). `SQLITE_BUSY_SNAPSHOT` returns *immediately*, so for that code the backoff is the whole cost; it cannot reach a synchronous call site today because every one of them is `IMMEDIATE`, single-statement, or read-only. The remaining store methods stay synchronous deliberately: converting them would change five port interfaces and ripple through every CLI consumer without making a single write non-blocking. The async twin's `await` between attempts is an **observable yield**, so a sibling writer may commit during the backoff — the outcome the backoff exists to allow — which makes the "`fn` must be one self-contained, re-runnable transaction" requirement load-bearing rather than incidental. - **Single-statement writes** (e.g. `appendMessage`, `setKeychainRef`) go straight for the write lock and need no explicit transaction — `BEGIN IMMEDIATE` would buy nothing, since a lone INSERT/UPDATE takes the write lock directly and cannot hit a read→write upgrade race. They do still route through `withBusyRetry` where a failure is user-visible data loss: the three `agent_sessions` / `session_messages` writers do (#228), because `busy_timeout` waits 5 s and then *fails*, and the chat persister calls them from inside a `RunEventBus` subscriber. - **Reads that must be consistent across statements** use a read transaction: `sessionStore.loadFull` reads the session row and its transcript inside one deferred transaction so **both reads observe a single consistent DB snapshot** (never a two-`SELECT` straddle across a concurrent commit). This now composes with **turn atomicity** on the write side: `sessionStore.writeTurn` appends a turn's messages and flushes the session row in ONE `BEGIN IMMEDIATE` transaction (#228), so a snapshot can no longer observe messages ahead of their totals, and a failed write leaves neither a half-written turn nor an unanswered `user` row that resume cannot roll back. This discharges the per-turn-transaction follow-up this section previously tracked. +- **The durable append is compare-and-append** ([ADR-0078](../../decisions/0078-ordered-durable-append-and-the-terminal-outbox.md) §2). `persistEvent` takes an optional `DurableWriteContext` carrying `expectedLastSequenceNumber` — the sequence the caller last *asked* to append, not the last it saw succeed. When present, the store reads `max(run_events.seq)` for that run **inside the same `BEGIN IMMEDIATE` transaction, through the transaction handle**, and refuses the append with a typed `AppendConflictError` when the two differ. `UNIQUE(run_id, seq)` bars a duplicate and says nothing about order or holes; this is what makes the committed log a *prefix* of what was asked rather than merely a set. Three properties are deliberate: the read is `max(seq)` rather than a denormalized `runs.last_event_seq` column, so there is no migration and no second source of truth that can drift from the rows; the check runs **before** the derived `runs`/`step_executions`/`run_costs` writes, so a refusal leaves nothing behind; and `AppendConflictError` is **not** in the retryable-code set above — a conflict is a stale belief, not lock contention, and retrying it five times would waste five transactions and report the wrong cause. The engine exempts the run TERMINAL from the guard, because exactly-one-terminal ([ADR-0036](../../decisions/0036-run-loop-substrate-event-bus-and-execution-host.md)) outranks it; a terminal the store will not take is ADR-0078 §4's outbox to own. +- **The same write is fenced by run ownership** ([ADR-0079](../../decisions/0079-cross-process-run-ownership-lease-and-fencing-token.md) §2). `DurableWriteContext` carries a second, **independent** claim beside `expectedLastSequenceNumber`: a `fence` of `{ ownerId, generation }`. When present, the store reads the run's `run_leases` row **inside the same `BEGIN IMMEDIATE` transaction, through the transaction handle** — outside it, the read and the write would be two statements another process could interleave, which is the exact race the check exists to close — and refuses with a typed `LeaseFencedError` when the owner or generation differs, **or when the row is absent**: a writer that cannot prove ownership fails closed. It is checked *after* the append guard, because a stale belief about the log is the more specific diagnosis when a writer has both problems. The two fields are independent because the run TERMINAL carries the fence *without* the append guard — exempt from one, not the other. An **absent** `fence` is a pass rather than a refusal: a caller holding no ownership claim has nothing stale to catch. Like `AppendConflictError`, `LeaseFencedError` is **not** in the retryable set — a stale fence is an expected refusal, not lock contention. - **Cross-platform:** `BEGIN IMMEDIATE` + the retry behave identically on every OS. The `0600`/`0700` at-rest guard below is a documented Windows no-op, so the concurrency test lane gates POSIX-permission assertions off Windows only.

They are RECORDED, + not re-derived: re-deriving ran `output_mapping` over the truncation preview, so a node whose result + exceeded the bounding ceiling put a different value into workflow state on the replay than on the + original. A replay is also refused when the node's `output_mapping` configuration differs from the one the + effect ran under — a workflow edited in the crash window is not a call we can answer from the record. It is host-side because only the host can compute the digest the comparison + needs — the engine is platform-free.

Classifying any of them as retryable reopens the hole. + +## 8. `needs_attention` + +An unresolved tier-3 effect is surfaced, never retried. The two surfaces differ deliberately. + +**A run** terminates as `run:failed` carrying a dedicated `ErrorCode` of `effect_needs_attention`. Three +shapes were weighed and two rejected: + +- a **new terminal event** — rejected for the reason ADR-0079 §5 rejected `run:fenced`: it widens ADR-0036's + exactly-one-terminal set and forces every surface, schema and checkpoint fold to handle a new variant; +- a **new `RunStatus`** — rejected because `runs.status` is a derived projection the event fold writes, so the + status would have to be invented in `applyDerived` rather than carried by the event that causes it; +- a **typed `ErrorCode` on the existing terminal** — chosen. It reuses the closed error taxonomy every surface + already switches on, and `run:failed` is honest: the run did not complete. + +**It does NOT report `durability: 'uncertain'`, and that is a correction to an earlier draft of this +section.** (The converse also holds: when a run's terminal write IS uncertain, that disposition outranks +this code — exit `5` or `6`. A caller who cannot trust the record cannot act on the reason the record +gives.) The disposition means exactly one thing +([ADR-0078](../../decisions/0078-ordered-durable-append-and-the-terminal-outbox.md) §5): did this run's +terminal reach the durable log. Here it did — the run recorded its failure correctly, and the only thing in +doubt is what a target did. Overloading the disposition would route the run to exit `5`, whose documented +remedy is "held in the outbox and retried on the next start"; nothing is pending, nothing will drain, and a +script following that advice waits forever instead of looking at the target. The discriminator is the +terminal's `ErrorCode`. + +The CLI maps that code to exit **`7`**, recorded in [commands.md](../cli/commands.md), for the reason +ADR-0079 took one — a caller must be able to tell "a human must look at this" from an ordinary failure, and +from the transient "another process owns this" of exit 6. It is the one code whose remedy is *do not retry*. +The run is **not** resumable past the unresolved effect; resuming it re-enters the gate in §4 and stops +again. + +**A session discloses once and does not block.** A chat has no operator queue and no run to pause, so +`chat-resume` reads its unresolved rows, renders them, and continues. Tier 3's actual guarantee — never +auto-retried, because nothing re-dispatches them — is unchanged; what changes is that the fact reaches the one +person who can act on it instead of halting a conversation. + +An operator resolves a row as **accepted** (the effect landed; treat it as committed) or **discarded** (it did +not; the node may run again). The resolution is written to the row with the actor and a timestamp. The CLI +command that performs it is a named follow-up, not part of this contract's first landing — the journal must +exist before anything can resolve rows. + +## 9. Retention + +- **Unresolved rows** (`prepared`, `dispatched`, `ambiguous`, `needs_attention`) are **never** swept by age. + They are the record an operator needs, and they outlive their run deliberately — the row carries no foreign + key to `runs`, because a purge is exactly when the record matters most. +- **`committed` rows** are swept only once their correlation can no longer be resumed. Sweeping a committed row + while its run is still resumable would delete the evidence the gate in §4 reads, reintroducing the duplicate. +Both sweeps ship: a run's committed rows go when the run reaches a terminal (it can no longer be resumed — +`resumeFromCheckpoint` returns a closed handle for one), and a session's go for every turn BEFORE the one +being resumed. The session half is the one that matters most in practice: `chat`, `chat-resume`, +`agent run` and the bare-`relavium` Home all write session-scoped rows, and leaving them forever would make +§11's digest a growing permanent oracle rather than a bounded one. + +- **Growth is bounded by resolution, not by time.** Unresolved rows accumulate until an operator clears them; + that is a deliberate trade against silently discarding an ambiguous external effect, and the quota/archive + mechanism for a neglected queue is a named follow-up. + +## 10. Durability scope + +**Process-crash durability, not power-loss.** `history.db` runs `synchronous = NORMAL` +([database-schema.md](database-schema.md)), which survives a process death but not an OS crash or a power cut. +CR-12's failure statement is process death; claiming more by silence is the class of overclaim this contract +exists to remove. + +## 11. Secrets: what a row may hold + +A journal row **never stores argument bytes**. It stores a digest of a **redacted projection** of the effective +args — every key named in `secretArgKeys` is excluded before hashing, not hashed and hidden. + +The reason is that a digest is a permanent equality oracle. A low-entropy secret (a short token, a URL with an +embedded key) is recoverable from its digest by dictionary attack, and on the CLI path `history.db` may be +unencrypted at rest. "A digest, not the bytes" is therefore not by itself a sufficient argument, and this +contract does not make it. The hash is SHA-256 over a canonical JSON serialization (sorted keys, no insignificant +whitespace) of the redacted projection, using a vetted implementation — never a hand-rolled one. + +## 12. The crash matrix this contract must be tested against + +Each is an acceptance point, not a suggestion: + +1. kill before the prepare commits · 2. after the prepare, before the target call · 3. after the target +completes, before the settle · 4. after the settle, before the tool-result event · 5. after the tool result, +before `node:completed` · 6. two effects in one node · 7. two processes preparing the same identity · +8. a settle write that fails · 9. tier 1 retry, tier 2 reconcile, tier 3 attention · 10. session +disclosure-once and a concurrent `chat-resume` · 11. the committed-retention sweep boundary. + +## 13. CR-95: the budget path must not become an effect duplicator + +A budget pause becomes a `paused` outcome, and an approval resets the node to `pending` and re-dispatches it +**from the start** — replaying every provider call and every tool call the turn already made. That makes the +budget path a duplicate-effect generator, independently of any crash. + +The rule: **from a turn's second provider egress onward, a budget verdict that would pause instead fails the +node closed** with the budget error, replaying nothing and issuing no further egress. The first egress still +pauses normally — nothing external has happened yet, so a replay costs one provider call. + +The two alternatives lose for opposite reasons: completing the loop past the cap spends money the user capped, +and pausing-then-resuming *is* the replay. Failing closed neither overspends nor duplicates, and is deliberately +the more disruptive of the two honest options. + +The long-term answer — checkpointing the continuation (provider messages, tool call/result pairs, round index) +so an approved pause resumes mid-loop instead of restarting — is a new durable artifact of a different shape. +Trigger: a user who must resume a partially completed tool loop rather than fail it. + +## 14. Known limitations + +- **The session path has no ownership guarantee.** ADR-0079 is runs-only, so two `chat-resume` processes on one + session can both dispatch. The UNIQUE prepare detects the collision but cannot distinguish a live prepare from + a dead one; the loser refuses rather than taking over. Trigger to revisit: the first supported concurrent-resume + flow. +- **A credential rotation changes the redacted projection**, so an effect whose args reference a rotated + credential gets a fresh identity and degrades to tier-3 behaviour for that occurrence. +- **A `!`-shell command after a resume can be refused as a false duplicate.** The shell's slot comes from a + per-session counter that restarts on `AgentSession.resume` — which a `/models` reseat also goes through — + because there is no durable source to restore it from: `!`-commands never enter the transcript, and the + platform-free engine cannot read `run_effects`. Two commands in one turn window followed by a resume can + therefore collide. It fails CLOSED (a refusal, never a repeated effect), and the fix is to persist the + counter with the session row. Trigger: the first surface where repeated in-window shell commands matter + enough to earn the schema change. +- **`EffectSlot` is not stable across a model replay**, which is why the gate is at node granularity. A design + that later needs slot-granular resume needs a durable record of the model response, which is CR-95's long-term + continuation checkpoint, not this. diff --git a/docs/reference/shared-core/expression-sandbox-spec.md b/docs/reference/shared-core/expression-sandbox-spec.md index a723a238..1a7304e2 100644 --- a/docs/reference/shared-core/expression-sandbox-spec.md +++ b/docs/reference/shared-core/expression-sandbox-spec.md @@ -98,7 +98,7 @@ concern, **not** part of this sandbox). **For an expression that completes within its resource caps, the result is a pure function of the injected scope** — the same scope always yields the same value (or the same deterministic language error).

The one SSRF primitive is reused, never re-implemented — see [security-review.md](../../standards/security-review.md). - MCP server credentials are injected from the secret store via a **stdio** server's `env` (e.g. `{{secrets.github_token}}`, resolved from the isolated `mcp-secret:*` namespace) and are **never** written into the workflow file or any event payload. See [../desktop/keychain-and-secrets.md](../desktop/keychain-and-secrets.md). `env` applies to the spawned stdio child only — a network (`http`, its deprecated `sse` alias, or `websocket`) transport has no process to inject into, so `env` is **rejected at parse** there (header-based auth for network MCP servers is a tracked follow-up, [../../roadmap/deferred-tasks.md](../../roadmap/deferred-tasks.md)). +- **A local stdio spawn requires the user's consent on that machine** ([ADR-0084](../../decisions/0084-consent-before-a-local-mcp-spawn.md)) — an artifact chooses the program, so the decision cannot belong to the artifact. The fingerprint, the grant store and the shared environment denylist are specified above as a cross-surface contract; a host that spawns without consulting it is the bypass. No credential enters the digest or the grant line. - Outbound (workflow-as-MCP) exposure is opt-in per workflow (only those listed in the adapter config are published). - All inbound MCP tool calls are schema-validated before dispatch, and tool inputs in events are sanitized — see [built-in-tools.md](built-in-tools.md) and [../contracts/sse-event-schema.md](../contracts/sse-event-schema.md). diff --git a/docs/roadmap/current.md b/docs/roadmap/current.md index ddeda7b3..b34ee890 100644 --- a/docs/roadmap/current.md +++ b/docs/roadmap/current.md @@ -89,8 +89,8 @@ any order"* — never as headcount. flowchart TD W0["Wave 0 — One true baseline
