Summary

  • Read this first: this PR is not behavior-neutral, despite the slice name. Commits 16–17 rewrite the shared claim-then-write protocol used by the live accept_inbound_message ingress path (real channel messages and trigger events). Two independent reviews found it behavior-preserving and, critically, the durable idempotency key byte-identical — had those bytes drifted, every existing idempotency record in production would have been orphaned and previously-accepted inbound messages would be re-accepted as new. Evidence is in Validation below. Review that hunk first.
  • The rest is slice 2a of R2 background subagents: it lands every new type, state, and method background delivery will need, with no production caller, so a deployed binary can read two new persisted-enum variants a release before any binary writes them.
  • Two persisted enums gain variants and neither has a tolerant reader: LoopInput (serialized whole into the durable run-queue document — one unparseable entry fails the entire run's queue) and ProcessDependencyState (journal rows). Readers-before-writers is the mitigation, and it is the reason this slice exists separately (design record D13).
  • Also: deletes confirmed-dead scaffolding (PostCapabilityStage::drain_settled, whose doc promised a LoopBackgroundChildPort that existed nowhere in the repo), and corrects the canonical design record against live code — it contained two claims that were simply false.

Review response (round 1-3)

Branch is now 34 commits, 27 files changed, 4101 insertions(+), 474 deletions(-) — grown from the original +2,844 by review response, almost entirely tests plus one kernel simplification that was a net deletion.

Eleven review comments, all dispositioned. Three did not hold and were rejected with evidence in-thread rather than implemented.

Security fix — the most consequential change here. Child-agent output written as MessageKind::System reaches the LLM provider's top-level system field (model_role_for_kind → ChatMessage::system → Role::System → convert_messages). Unframed, a prompt-injected child could have written the parent's system prompt. Framing is now enforced by type: FramedSubagentText, sole constructor frame(), no Deserialize, no From<String>, no public field. Red-proven by reducing frame to the identity function.

Kernel simplification. ProcessDependencyState::legal_predecessors() makes the delivery lifecycle a total relation the kernel owns, and expected was dropped from the transition request entirely — the CAS now derives the precondition instead of trusting the caller's assertion. Only possible in this PR: TransitionDependency is a journaled command with zero producers today, so no instance exists in any deployment; after the next slice it becomes a durable-format change. It deleted a peek, a wildcard predecessor selector, a bespoke matches!, and four duplicated closed-state predicates.

Design-record correction (D14). §4.1 prescribed binding the delivered row to a queue entry "exactly as steering rows do." That cannot work — the row is System/Finalized and ensure_user_accepted admits only User rows in Accepted/DeferredBusy/Queued, so the status flip fails permanently, retained flips consume the 32-entry cap, and the run eventually returns CapacityExhausted for everything including human steering. The row is right; the doc was wrong. A crate-tier test now pins the refusal so the next slice meets it as a red test.

Also: store.rs split back to 443 lines (below the 504 this PR started from); caller-level drain tests through InputStage::process; a subagent-door race test; malformed-metadata fail-closed coverage; and every line-pinned citation this PR introduced converted to symbol names — three had already drifted within the branch.

Change Type

  • Refactor
  • Documentation

Validation

  • cargo fmt --all -- --check
  • cargo clippy --all --benches --tests --examples --all-features -- -D warnings
  • cargo build / cargo check --workspace --all-targets → 0 errors
  • Relevant tests pass: ironclaw_loop_contracts, ironclaw_agent_loop, ironclaw_processes, ironclaw_threads, ironclaw_turn_runner, ironclaw_architecture_tests, plus reborn_integration_subagent_await_edge and reborn_integration_tool_call
  • bash scripts/preflight-gates.sh — run locally and required: CI's only architecture-suite invocation is cargo test -p ironclaw_architecture_tests reborn, a test-name filter, so the loop-port scan, the process-storage scan, the four composition_* gates and the threads name-collision gate report "0 tests" in PR CI. A green PR does not prove they ran.
  • Manual testing: none — nothing in the new surface is reachable at runtime (see below).

Two local results that are NOT regressions from this branch, characterised so a reviewer does not chase them:

  1. reborn_integration_tool_call::current_tool_surface_overrides_stale_assistant_unavailable_claim overflows its stack in a debug build on this machine. It is pre-existing: it reproduces identically at the merge-base 8fda17c59 in a clean detached worktree with none of this branch's changes present. It is not infinite recursion — it passes with RUST_MIN_STACK=67108864. The other 37 tests in that binary pass, including both deny-filter pins.
  2. One preflight-gates.sh gate (charter: ironclaw_assistant) failed on a libsql-ffi build error (BFD assertion fail from the system assembler, missing sqlite3.o), not on an assertion. Re-run directly, that suite passes 297/297.

Idempotency-key byte-identity evidence. The key is sha256 over serialize_pretty(InboundIdempotencyKey). All seven declarations in its dependency closure (InboundIdempotencyKey, ThreadScope, serialize_pretty, sha256_hex, idempotency_record_key, idempotency_record_path, InboundIdempotencyRecord) plus their derive attributes were extracted at both dc165435d and 43ef0113f and diffed: identical. contract.rs in that range is purely additive (25 insertions, 0 deletions), so ThreadScope's wire shape cannot have drifted.

Test Strategy

User behavior: No user-visible change. builtin.spawn_subagent remains deny-filtered, so no model can reach the new surface; the ingress refactor preserves existing message-acceptance behavior.

Risk areas:

  • Side effect
  • Persistence
  • Security or permissions
  • Cross-component behavior

Tests added or updated:

  • Unit or contract: ProcessDependencyState wire-spelling + historical-forms pins; the expected-state CAS matrix (idempotent replay vs illegal jump vs terminal-target refusal); AwaitEdgeState projection matrix; all seven historical LoopInput wire tags; both drain modes for the new input; accept_subagent_result across both production backends including two fault-injection cases.
  • Reborn integration: reborn_integration_subagent_await_edge (the projection pin, unmodified) and reborn_integration_tool_call (the deny-filter pins, unmodified).
  • Recorded fixture: Not applicable: no model interaction changes.
  • Browser E2E: Not applicable: no frontend surface.
  • Backend or runtime: covered by the contract suites above; both thread backends exercised behind Arc<dyn SessionThreadService>.
  • Live canary: Not applicable: the capability is deny-filtered.

What the tests prove: (1) every state the store can reach is also exitable, asserted end-to-end including that the deferred branch releases its reservation; (2) the new fields survive the projection against the blob shape production actually writes — an earlier revision was green only because its fixture seeded a shape production never produces, and the fixture now builds a real AwaitedChildSetRecord; (3) both acceptance doors share one dedupe index and the system-class collision guard holds — proved non-vacuous by weakening each half on both backends, where deleting the kind != System guard makes the service return a user's message as a subagent result with idempotent_replay: true; (4) adding a hypothetical terminal dependency variant now yields exactly one E0004, in the file that owns the paired reservation release.

Commands run: cargo fmt --all -- --check · cargo clippy --all --benches --tests --examples --all-features -- -D warnings · cargo check --workspace --all-targets · cargo test -p ironclaw_loop_contracts -p ironclaw_agent_loop -p ironclaw_processes -p ironclaw_threads -p ironclaw_turn_runner -p ironclaw_architecture_tests · cargo test --test reborn_integration_subagent_await_edge --test reborn_integration_tool_call · bash scripts/preflight-gates.sh

Security Impact

A child agent's delivered result is written as MessageKind::System, never MessageKind::User, so untrusted agent text can never be indistinguishable from a human instruction on the thread. Asserted on both backends and re-asserted after load_context_messages, so a projection that silently reclassified the row would fail. actor_id is None. The collision guard refusing a non-System row for a subagent identity is now pinned by test. builtin.spawn_subagent stays in disabled_capability_ids; that file is untouched and its integration pins are unmodified.

Reborn Trust-Boundary Checklist

  • Public policy/evidence/trust-bearing types: the new TransitionProcessDependencyRequest is constructible only within ironclaw_processes' one port implementation; ProcessDependencyPort has exactly one impl workspace-wide, zero decorators, zero doubles.
  • Untrusted content enters prompts only through an envelope/escaping primitive: unchanged — this slice adds no prompt path.
  • Hashes declare purpose: unchanged; the existing sha256 idempotency key is reused verbatim (byte-identity verified above).
  • New/changed status/error variants: downstream match sites audited. ProcessDependencyState gained three variants; every match site was audited and all three correctly index as not closed (rows.rs derives closed from the state column alone). SessionThreadError::InvalidSubagentResult required arms in ironclaw_assistant and tools/ironclaw_stress; both are in this PR. Command: cargo check --workspace --all-targets → 0 errors.
  • Security/durability serde(default) fields fail closed: ProcessDependencyRecord.transitioned_at is #[serde(default, skip_serializing_if = "Option::is_none")]; historical rows decode unchanged and never-transitioned rows serialize byte-identically.
  • Queues/maps/buffers/counters bounded: unchanged.
  • Errors have stable class semantics: new refusals are typed InvalidRequest/Backend consistent with the surrounding code.
  • Sandbox/native/host names: unchanged.

Database Impact

Two persisted enums gain variants with no tolerant reader: ProcessDependencyState (journal rows) and LoopInput (durable run-queue document, deserialized whole — one unparseable entry fails the whole run's queue). Nothing in this PR writes the new variants; the writers land in slice 2b. That ordering is the compatibility strategy: deploy this first so every binary can read the new forms before any binary emits them. Historical values are pinned by round-trip tests on both enums. No migrations; no schema change; no backend-specific behavior.

Blast Radius

ironclaw_loop_contracts, ironclaw_agent_loop, ironclaw_processes, ironclaw_threads, ironclaw_turn_runner, one match arm each in ironclaw_assistant and tools/ironclaw_stress, plus the design record.

The one genuinely risky surface is the shared acceptance protocol in filesystem_service.rs: it is on the live inbound path for channel and trigger messages. If it were wrong, the symptom would be duplicate or lost inbound messages under a crash between the idempotency claim and the row write. Everything else is unreachable at runtime — verified mechanically: no construction or call of LoopInput::SubagentSettled, transition_process_dependency, the three AwaitEdgeStore methods, or accept_subagent_result exists outside #[cfg(test)].

Rollback Plan

Revert the whole branch — safe at any time, because nothing writes the new persisted variants. If only the ingress refactor is suspect, revert 538dd05cb and 43ef0113f (plus their compile-fix arms in dba5f41e9 and 32a8681dd); the inert slice stands alone without them. Do not ship slice 2b before this is deployed everywhere, or old binaries will meet variants they cannot parse.

Review Follow-Through

Known and deliberate, carried to slice 2b rather than fixed here:

  1. validate_subagent_acceptance_identity checks emptiness only, while the repo's existing external-identity rule (ironclaw_extension_contracts/src/external.rs:12-32) also enforces a length cap and rejects control characters. source_binding_id lands verbatim in durable state, so those checks matter; latent today with no producer.
  2. The resume-race recovery branch has no test in either door. Its equivalence across the refactor is established by static reading, not execution.
  3. record_attention's predecessor selector uses a _ => wildcard over AwaitEdgeState — fail-closed, but a future legal predecessor is admitted silently rather than as a compile error.
  4. AwaitEdgeStore::close returns Ok(()) on ResultAppended — a silent success that leaves the reservation held; should become a typed error once a producer exists.
  5. The CAS accepts non-terminal rewinds (Settled -> Open on a record already carrying settled_at). Unreachable with no producer; wants a forward-only assertion when 2b adds writers.
  6. filesystem_service.rs grew 4,533 → ~4,899 lines against the standing "leave touched files no larger than found" rule, in a file already ~4.9× the 1k ceiling and already carrying submodules. The crash-safety-in-one-place argument for the shared helper is sound, but the file is moving the wrong way; an acceptance submodule is the natural home.
  7. 538dd05cb is labelled refactor yet tightens subagent-door recovery (rejecting a thread mismatch and a non-System row). Disclosed in its own message; on the inert door only.

Review track: C (security/runtime/DB)

henrypark133 and others added 23 commits August 20, 2026 23:34
Add LoopInput::SubagentSettled { child_run_id: TurnRunId, message_ref:
LoopMessageRef } — refs only, no child content (D4). Inert surface: nothing
constructs this variant outside tests in this slice; Task 2 wires production
use.

Widened the existing ironclaw_host_api::turn import in input.rs to include
TurnRunId rather than adding a second import path.

cargo check --workspace after adding the variant reported exactly one
non-exhaustive-match site: crates/loop/ironclaw_agent_loop/src/executor/input.rs:188
(consume_drainable_inputs). Added SubagentSettled to that barrier arm
(break, same as GateResolved/CapabilitySurfaceChanged) as a deliberately
temporary placement — Task 2 moves it into the drainable arms.

Establishes the first serde tests for LoopInput: a round-trip test pinning
the snake_case tag, and a historical-wire-forms test guarding the durable
run-queue document (durable_input_queue.rs:109), where a parse failure
corrupts the whole queue rather than one entry.

SubagentSettled now drains like UserMessage/Steering in the Steering
mode and additionally in FollowUp mode, matching the rationale already
documented for Steering-during-final-call. Removing it from the
control-barrier arm required adding it to the exhaustive match's
drainable-variant arm in consume_drainable_inputs so the match stays
exhaustive (that arm is unreachable at runtime for it since both drain
modes now catch it first).

…ugh match

The prior comment claimed FollowUp was unreachable in the fall-through
match, but Steering mode does not drain FollowUp inputs, so a
FollowUp-variant input genuinely reaches that arm (and breaks, left
unconsumed) when draining in Steering mode. Narrow the comment to what
is actually unreachable: UserMessage, Steering, and SubagentSettled,
which both mode arms drain. Also aligns the Steering arm's brace style
with the structurally parallel FollowUp arm (cosmetic only).

No control-flow change.

PostCapabilityStage::drain_settled() has been dead since it was scaffolded:
it always returned an empty Vec, its single call site bound the result to
_drained and never read it, and its doc comment promised a
LoopBackgroundChildPort that exists nowhere in the repository. The real
settled-background-subagent delivery path is LoopInput::SubagentSettled
(tasks 1-2 of this slice). Remove the fn, its call site, and the stale R2
doc paragraph; renumber the surviving R1 compaction doc to plain prose
since the R1/R2 split no longer exists.

Structural only — no behavior change. Verified drain_settled and
LoopBackgroundChildPort are referenced nowhere else in crates/ or tests/
(word-boundary grep), and cargo test -p ironclaw_agent_loop --no-fail-fast
is green (565 tests, 0 failed).

…nsition

Delivering a settled dependency's result to its dependent is three durable
facts, not one, and a crash can land between any two of them. Give the
kernel dependency state machine the three in-flight states that sit between
`Settled` and closure — `ResultAppended`, `AttentionScheduled`,
`AttentionDeferred` — plus one expected-state compare-and-swap
(`ProcessDependencyPort::transition_process_dependency`) that advances the
state column only when it still holds the state the caller expects, so a
half-applied step can be replayed without double-applying the next one.

The names stay kernel-neutral: the state column says what happened to the
edge, not which product feature produced it. Keeping all three on the column
(rather than one of them in metadata) keeps any projection over these rows a
total function of the state column.

Inert surface: nothing outside the contract tests calls the new operation or
writes the new states in this slice.

Persistence notes:
- The enum is serialized verbatim into journal rows with no tolerant-reader
  fallback, so the four historical spellings are pinned by a test and the
  three new ones are pinned as durable format too.
- `ProcessDependencyRecord` gains `transitioned_at`, `#[serde(default)]` and
  skipped when absent, so historical rows still decode.
- All three new states are in-flight: the persisted `closed` index and both
  query predicates derive closedness from `Consumed | Abandoned` alone, so
  the new states index as open and stay visible to the host recovery scan —
  asserted through the real index, not just the in-memory filter.

The loop-tier await-edge projection had an exhaustive match over the enum;
its three new arms fold onto `AwaitEdgeState::Settled` (marked `ponytail:`)
until the slice that walks the delivery chain gives it real arms.

…at releases the reservation

Two holes in the delivery state machine added by the previous commit, both
found in self-review and both closed here.

The expected-state CAS could write `Consumed`/`Abandoned` into the state
column. It writes that column and nothing else, so that was a second door to
a terminal state that skipped `release_dependency_reservation` — precisely
the compensating dual write this crate's AGENTS.md forbids, and it would
have leaked one descendant slot per closed edge forever. Both terminal
targets are now refused up front, before the record lookup and before any
mutation, with a reason naming the operation that closes the edge and
releases the reservation in the same journal command. Refusing before the
expected-state check keeps the answer deterministic: reaching for the wrong
door gets the same error whatever the stored state is.

`consume_process_dependency` required exactly `Settled`, which made
`AttentionScheduled` a state an edge could enter and never leave. It now
accepts `Settled | AttentionScheduled`, and deliberately no further:
`ResultAppended` has no attention recorded yet, and `AttentionDeferred` is
parked on purpose so an unclosed-query sweep can still find it. Closing
either would strand the dependent with a result it never looks at. Abandon
is unchanged — a parent that gives up mid-delivery must still return tree
capacity from any non-terminal state.

The state machine is now closed under its own rules: every state the CAS can
reach has an exit, and every path to a terminal state releases the
reservation atomically.

The wrong-expected-state test targeted `Consumed`, which the new guard makes
unconditionally illegal; it would have started passing for the wrong reason,
so it now targets a legal state and still tests only the expectation
mismatch.

Still inert: nothing outside the contract tests calls the transition
operation or writes a delivery substate.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Task 4 added three in-flight delivery states to the kernel's
`ProcessDependencyState` and left `AwaitEdgeStore::edge_from_record`
collapsing all of them onto `AwaitEdgeState::Settled` behind a `ponytail:`
marker, because the loop-tier enum had no arms for them. Give it the arms
and retire the marker.

- `AwaitEdgeState` gains `ResultAppended`, `AttentionScheduled`, and
  `AttentionDeferredStreakCap`. The kernel's `AttentionDeferred` stays
  domain-neutral; the loop tier is the layer that knows what a streak cap
  is, so the names differ on purpose.
- `AwaitEdge` gains `appended_message_ref` and `attention_outcome`, both
  optional and skipped when absent, plus the `AttentionOutcome` enum.
- Three store methods walk the chain over the kernel's expected-state CAS:
  `record_result_appended` (Settled -> ResultAppended, carrying the
  parent-thread message ref), `record_attention` (-> AttentionScheduled),
  and `defer_streak_capped` (-> AttentionDeferred). Their metadata is
  *merged* into the record's blob, which is the serialized edge itself.
- `close` consumes only `Settled | AttentionScheduled` — the two states the
  kernel will close — and leaves the in-flight ones parked, matching the
  journal's refusal to strand an undelivered result. Closing still goes
  through `consume`, never the state-column CAS.
- `reservation_release` is unchanged: `Released` for `Consumed | Abandoned`
  only. All three new states are in flight and stay `Unclaimed`.

The projection matches remain exhaustive with no wildcard — that
exhaustiveness is what surfaced this site in the first place. Boot recovery
gains explicit no-op arms with a `ponytail:` naming the sweep that lands
with the producer; nothing outside tests writes these states in this slice.

…pend

`record_attention` targets `AttentionScheduled` with `ResultAppended` as its
expected state, so scheduling attention before the child's result is durably
appended is refused by the kernel's expected-state CAS. Nothing pinned that
ordering: widening `record_attention`'s expected state to `Settled` left the
whole suite green except the lifecycle walk, which failed for the unrelated
reason that its second step no longer matched.

Pin it directly — the refusal surfaces as an error carrying the kernel's
cause, and the refused transition leaves the edge exactly where it was.
Covers `AttentionOutcome::Activated`, which the lifecycle walk does not reach.

`AttentionDeferredStreakCap` was a dead end. `record_attention` hard-coded
`ResultAppended` as its expected state and the kernel's `consume` takes only
`Settled | AttentionScheduled`, so a parked edge had no forward path and no
closing path — it could only be abandoned. That contradicts design §4.1/§4.2,
where a streak-capped edge stays unclosed "until a permitted or human-initiated
run start drains it": draining *is* scheduling attention.

`record_attention` now advances from either legal predecessor. The kernel CAS
takes one expected state, so the store reads which of the two the edge stands
on and hands that observation back as the expectation. The guard is intact:
the expectation is still asserted against stored state inside the journal
command, so a concurrent writer that moved the row in between makes this write
lose. An edge on neither legal predecessor falls through to `ResultAppended`
and is refused by that same check — this is a two-element legal set, not
"advance from anywhere", and the kernel CAS contract is unchanged.

Tests: the deferred branch is now proven closeable end to end — parked, `close`
a no-op while parked, drained forward by attention (keeping the already-appended
message ref), then consumed with no dependency left unresolved. Also pinned that
replaying attention keeps the first outcome.

`the_delivery_chain_refuses_to_skip_the_append` from 9b8071d was written to
catch a naive widening of this expected state to `Settled`; it stays green
before and after this change, which is the evidence that one specific door
opened rather than the guard loosening. A near-identical refusal test I had
written separately was dropped in favour of that pin, with its one extra
assertion folded in.

… the real production blob

edge_from_record's fallback branch hardcoded appended_message_ref: None and
attention_outcome: None, on the assumption that the fallback (AwaitedChildSetRecord)
shape was a legacy path. It is not: subagent_spawn_port.rs is the sole production
writer of dependency metadata and it always writes that shape, so
from_value::<AwaitEdge> always fails against real data and the fallback always
fires. The delivery-chain CAS merges appended_message_ref/attention_outcome into
that same blob as sibling top-level keys (additive merge, never a replace), so the
durable blob carries both fields — the fallback just never read them back,
discarding them on every projection and breaking the documented replay-safety of
record_result_appended/record_attention against real production data.

Existing tests missed this because settled_background_edge opened its fixture
dependency with a full AwaitEdge-shaped blob (serde_json::to_value(&edge)), which
production never writes and which takes the primary parse branch instead of the
fallback. Switched that fixture (and legacy_edge_metadata_fallback_and_malformed_metadata_fail_closed,
via a new shared awaited_child_set_record() helper) to the real
AwaitedChildSetRecord shape, which is what exposed the bug: four tests went red
with the fallback hardcoded to None, confirming the finding.

Also: renamed record_attention's shadowed `outcome` local to `outcome_value`, and
corrected two module-doc clauses in mod.rs — abandon reaches any non-terminal
state (the kernel's close-dependency guard only gates consume), and
AttentionDeferredStreakCap is not consumable from here but is still abandonable.

Adds `SessionThreadService::accept_subagent_result` — the durable door a
background child's framed result enters the *parent's* thread through,
exactly once across a crash-and-replay.

- The row is `MessageKind::System` / `MessageStatus::Finalized`, never
  `MessageKind::User`: a child's output is untrusted agent text, not a
  human instruction on the steering contract.
- Dedupe reuses the ONE existing acceptance index — the flat SHA-256 of
  `(scope, source_binding_id, external_event_id)` that `accept_inbound_message`
  already writes — rather than adding a second one. Both halves of the
  identity arrive as caller-supplied strings; this crate cannot see run
  identity (no `ironclaw_processes` edge) and derives nothing.
- Two-phase claim on backends without transactions: the idempotency record
  is written before the row, so a crash in between leaves a durable recovery
  intent and the retry resumes the SAME message id instead of appending the
  result twice. A retry whose payload disagrees with the claim fails closed
  on a content-free fingerprint.
- `IdempotencyState` is the former `InboundIdempotencyState` made generic in
  the accepted-reply shape so both doors share one classification; the large
  `Pending` payload is boxed.

The trait method carries a fail-closed default (house convention, #7752), so
the 11 test doubles stay at zero diff — and the `Arc<S>` blanket forward is
added, because a forgotten forward inherits that default silently. Both
production backends implement it for real.

Nothing calls it: this slice lands inert surface only.

Recon against live code found four categories of false or stale claims in
the canonical subagent design record: an overclaimed in-memory queue with
no compat concern (production is filesystem-backed and deserializes the
queue document whole), an overclaimed GateResolved precedent (zero
producers, treated as a barrier — SubagentSettled is the first host-side
settlement input), four wrong file paths/scopes in the Part II task list,
and two undocumented decisions (three kernel substates instead of two, and
the 2a/2b/2c slice split). Also marks the inert surface slice 2a already
shipped and records two open items found during 2a and left for 2b.

… unknown thread

A child's framed result may only land in a thread that already exists under
the caller's scope. The door must not conjure a thread — and because it claims
the acceptance identity BEFORE the row on backends without transactions, a
rejected acceptance must not burn the identity: the retry has to be rejected
again rather than come back reporting an idempotent replay of a row that was
never written.

Covers both production backends behind `Arc<dyn SessionThreadService>`.

… date

Task 5's Files bullet still named only ResultAppended and
AttentionDeferred for ProcessDependencyState, contradicting D12 (added
in the same prior commit) which records the deliberate three-variant
decision. Name all three and point at D12. Also bump the "Last
verified against code" date to 2026-08-21 to match the latest
verification pass.

…ject

`subagent_result_into_an_unknown_thread_fails_closed` documents a
non-transactional-backend property it never reaches: both backends it runs on
either commit the identity claim with the row or never write one, so neither
enters the state the comment describes.

Refusing `BeginTxn` forces the two-phase fallback. The recorded backend traffic
confirms the window is real — claim `WriteFile` lands at the idempotency path,
then the thread `ReadFile` misses — leaving a durable claim pointing at a row
that will never exist. The retry must still be rejected: an orphan claim must
never be mistaken for a committed row and replayed back as an accepted result.

The property is defended twice (the classifier verifies the thread before
reading the message, and a missing row resumes rather than replays), so the
test only goes red when both guards are removed — verified by mutation, with
the two pre-existing unknown-thread cases staying green throughout.

…eptance doors

`accept_subagent_result`'s `TransactionalMessageWrite::Unsupported` arm was a
second copy of `accept_inbound_message_with_replay_metadata`'s: the same
`CasExpectation::Absent` claim before the row, the same `VersionMismatch`
re-classify-and-resume recovery, the same `reserve_sequence` ->
`write_new_message` -> resume-race read. Only the classifier, the reply shape,
and the diagnostic strings differed — and the two had already drifted apart on
day one.

Lifts that arm into `write_new_message_claiming_identity_first`, parameterized
by a `FallbackAppend` describing where the row lands and which identity claim
guards it, plus the door's `classify` closure returning `IdempotencyState<T>`.
Both doors now call it. The crash window that stops a message being appended
twice is closed in exactly one place, so a fix to it can no longer reach only
whichever copy a bug report names.

No behavior change on any covered path:
- The inbound resume-race read moves from `accepted_message_from_idempotency_path`
  to `idempotency_record_from_path` + `classify`. Both yield `Accepted` under
  exactly the same condition (the row exists and the actor matches); every
  other outcome falls through to the original write error as before.
- The subagent resume-race read moves from a bare `read_message_versioned` to
  the same `classify_subagent_idempotency_record` the rest of that function
  already uses, which additionally rejects a thread mismatch or a non-system
  row. Identical on the happy path, strictly fail-closed on the mismatch.
- Claim-conflict diagnostics are now built from the door's write label.

Regression net (all green, unchanged): `filesystem_fallback_idempotency_failure_precedes_message_persistence`,
`filesystem_fallback_resumes_intent_with_original_model_after_message_failure`,
`filesystem_fallback_accept_concurrent_duplicate_replays_existing_message`,
`filesystem_transactional_accept_concurrent_duplicate_replays_existing_message`.

Drops the `ponytail:` marker that named this duplication as accepted debt — the
debt is paid, and a marker for debt that no longer exists is its own defect.

`("", "")` hashes to a perfectly valid dedupe-record key. A producer that
forgot to populate `external_event_id` would therefore collapse every child of
every parent onto one row and get `idempotent_replay: true` back for all of
them — a fail-OPEN shape in the one door whose entire job is fail-closed
dedupe, and one that looks like success at every call site.

Both halves are now validated (non-empty after trim) before the identity is
hashed, on both backends, via one `validate_subagent_acceptance_identity`
beside the existing `validate_attachment_refs`. Rejection is typed:
`SessionThreadError::InvalidSubagentResult` — a caller error, following
`InvalidPreparedContext`, never `Backend`.

Also pins two promises that had no in-tree proof:

- `a_backend_without_the_door_fails_closed` drives the trait's fail-closed
  default through a backend that implements every REQUIRED method and
  overrides nothing else — the exact shape of the 11 test doubles this slice
  left at zero diff. Without it the default's correctness rested on
  uncommitted mutation evidence.
- `filesystem_fallback_unknown_thread_claim_is_not_replayed_as_accepted` now
  asserts the burned identity HEALS once its thread exists. The rejection
  assertions alone were not load-bearing: an orphan claim read as a committed
  row still surfaces `UnknownThread` on the retry from a later stage, so the
  test passed against that exact bug. Verified by mutation — making a
  row-less claim classify as `Accepted` now fails this test.

43ef011 added SessionThreadError::InvalidSubagentResult but left the
exhaustive match arm in map_thread_error uncommitted, so the branch did
not build. Verified both ways: without this arm cargo check -p
ironclaw_assistant fails with E0004 non-exhaustive patterns; with it the
crate builds clean.

`apply_transition_dependency` refuses to let the state-column CAS close a
dependency edge, because closing and releasing the descendant reservation are
one journal command (crate AGENTS.md:40). The refusal matched `Consumed` and
`Abandoned` and swept everything else into a `_ => None` wildcard.

That wildcard is fail-open on an enum this branch just proved gains variants
(it gained three). A future terminal variant would fall through it, get written
by the CAS, and permanently leak the descendant reservation slot: rows.rs:1563
indexes the row as closed, `apply_close_dependency` returns early as
already-terminal, and nothing ever releases the reservation. Silent, permanent,
no compile error.

Enumerate the five non-terminal variants instead. Adding a terminal variant now
fails to compile in the one file that owns the paired release.

The design constraint of the thread-service work is that the subagent-result
door reuses the inbound door's `(scope, source_binding_id, external_event_id)`
index rather than opening a second parallel one. Both `contract.rs` and
`filesystem_service.rs` assert this in prose; no test observed it. Every case
in this suite drove one door at a time, so a refactor giving the subagent door
its own index path would have left all of them green.

Equally untested was the fail-closed collision guard that keeps a user or
steering row from being handed back to a parent as its child's result.

One case per production backend closes both gaps: claim the tuple through
`accept_inbound_message`, then offer the same tuple to `accept_subagent_result`
and require a `Backend` error naming the non-system row, with the thread still
holding exactly the one user row.

Proven non-vacuous by weakening each half in turn, both backends:
  - delete the `kind != System` guard -> both new cases fail, returning the
    user row as `AcceptedSubagentResult { idempotent_replay: true }`;
  - namespace the subagent door's index key -> both new cases fail, minting a
    second row at sequence 2.
In both weakenings the other 13 cases in the file stayed green, which is the
coverage gap this commit closes.

`historical_loop_input_forms_still_deserialize` pinned 4 of the 7 variants,
leaving `interrupt`, `cancel`, and `capability_surface_changed` unguarded.
`LoopInput` is serialized whole into the durable run-queue document, where one
unparseable entry corrupts an entire run's queue rather than one message, so a
half-pinned tag set is the gap the test exists to close.

Verified non-vacuous: renaming `Interrupt`'s field on the wire turns the test
red with `missing field 'interrupt_kind'`.

The date advanced to 2026-08-21 but the hash stayed at `e4225c442`, which

dba5f41 fixed only the ironclaw_assistant match site because it was
verified with 'cargo check -p ironclaw_assistant' rather than at
workspace scope. tools/ironclaw_stress is a workspace member and its
thread_failure match is exhaustive with no wildcard, so the workspace
still failed to build with E0004.

Verified this time at the right scope: 'cargo check --workspace
--all-targets' now reports 0 errors.

832-847: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Do not reserve a second sequence for an adopted pending claim.

A concurrent duplicate can classify the claim as Pending, reach Line 832 before the original writer persists the row, and reserve a second sequence. Its absent write then fails, and Lines 842-847 return the accepted row. The second reservation remains consumed.

This affects both inbound and subagent acceptance because both use this helper. Persist the reserved sequence with the durable claim, or otherwise make claim resumption reuse one sequence. Extend the race test to force this interleaving.

…ain caller

`consume_drainable_inputs` is a pure function: it classifies inputs and
advances the cursor, and that is all a test at that level can see. The
sequence a settled subagent result actually depends on lives one layer up in
`InputStage::process` — write the `BeforeModel` checkpoint of the advanced
cursor, and only then ack, because the ack is what flips the queued
transcript row to `Submitted` and makes it model-visible.

Drive `[SubagentSettled, GateResolved]` through `InputStage::process` in both
user-facing drain modes and pin both halves: the settled input advances the
cursor, checkpoints it, and is the only token acked; the gate is a barrier
that stops the drain with its own ack token untouched.

Both doc comments in the acceptance suite and twenty citations added to the
design record pinned cross-crate call sites by absolute line number. Nothing
fails when those drift, and three of the six numbers in the steering-ladder
comment already resolve to unrelated code — two of them to a bare `}` —
inside the branch that wrote them.

Cite the symbols instead: `ensure_user_accepted`, `is_model_visible`,
`MAX_QUEUED_INPUTS_PER_RUN`, `is_settled`, `flip_submitted`. They were
already in the prose, so nothing is lost and the citations survive a
refactor. Five design-record citations named no symbol and were given one,
each resolved against the tree first. The two pre-existing line citations are
left alone.

Comment thread crates/loop/ironclaw_agent_loop/src/executor/tests/reply_input.rs
Two review findings on `FramedSubagentText`.

`#[serde(transparent)]` removed. The filed security concern does not
apply — the type derives `Serialize` only, so there is no wire
construction path to bypass `frame()`, and `.claude/rules/types.md`
aims that flag at `transparent` + derived `Deserialize`. But the
attribute is dead weight: the type's one serializer is
`subagent_acceptance_fingerprint`, and serde_json emits a plain newtype
struct as its inner value, so the persisted fingerprint bytes are
unchanged (verified with a throwaway equality test). It also leaves a
trap for whoever later adds `Deserialize`. Gone, and named in the doc
comment alongside the other deliberate absences.

Neutralization stays one-way. The second finding read the framed value
as the only copy of the child's output; it is a derived copy in the
*parent's* thread. The child's verbatim text is a finalized assistant
row in the child's own thread — `child_terminal_output` reads it back
to build this one — and nothing on the settle path deletes or redacts
it (`delete_thread` has no production callers). "LLM data is never
deleted" governs the row, not every projection of it; the sibling
`sanitize_untrusted_terminal_reason` already truncates the same text to
512 bytes. A reversible escape would buy retention already guaranteed
at the source while handing an injected child escape syntax to reason
about from inside the delimiters. The doc comment now says so.

…nd and final state

checkpoint_kinds() only proves a BeforeModel checkpoint happened; the final
in-memory cursor only proves the executor's own state advanced. Neither
proves what cursor value the checkpoint payload actually carried, so a
regression that persists a stale cursor and only later advances the
in-memory one would still pass. Decode the staged BeforeModel payload
(MockHost already captures it via staged_payloads()) and assert its cursor
directly, in both drain modes.

The acceptance-protocol refactor appears behavior-preserving, and the new persisted variants have no live runtime producers in this slice. No production-breaking issues found.

Checks: cargo fmt --all -- --check passed; targeted Rust tests could not link because cc was unavailable; focused static review completed, and GitHub CI had no failures observed (some checks still running).

Slice 2a refactors the live accept_inbound_message path onto the shared write_new_message_claiming_identity_first helper and adds the (currently inert) accept_subagent_result door plus kernel delivery substates. Traced the live surfaces against the original inline logic and they preserve existing behavior; the new delivery states/CAS transition have no runtime producer yet.

  • accept_inbound_message refactor (shared claim helper): claim-put → VersionMismatch → classify → Accepted/Pending resume is equivalent to the old inline path; replay_metadata/idempotent_replay propagation and idempotency key bytes are unchanged.
  • Kernel consume/abandon: the legal_predecessors guard reproduces prior Open/Settled behavior (is_closed() == old matches!(Consumed|Abandoned)); new substates are inert.
  • agent-loop drain / post_capability: only add inert SubagentSettled arms and remove dead drain_settled.

Non-blocking follow-ups (all verified inert or pre-existing, not merge-blocking): a wasted-sequence-number reservation already present on the inbound path (no data loss/dup, ordering unaffected) and a stale doc §4.1 reference.

Checks: cargo fmt --all --check and git diff --check clean; ironclaw_loop_contracts 151 passed (incl. LoopInput snake_case + historical wire-tag pins); subagent_result_acceptance 23 passed (both backends); ironclaw_threads inbound-fallback/idempotency regressions 3 passed; process_journal_store_contract 67 passed (CAS + consume/abandon on libSQL and Postgres); CI green with two affected-crate buckets still pending at last refresh.

* feat(loop-host): spawn codec and schema accept background mode

Task 1 of the background-subagents slice: the spawn-args wire codec now
decodes mode: "background" (and the legacy run_in_background: true flag,
treated as an alias) instead of rejecting it, and the generated tool schema
advertises the mode property. A contradictory mode: "blocking" +
run_in_background: true pair is rejected as a model-correctable
InvalidInvocation naming the conflict. finish_spawn still hardcodes
SpawnSubagentMode::Blocking pending Task 2, which consumes args.mode.

* refactor(loop-host): bind_input_enqueue on the settler seam

Add AwaitEdgeSettler::bind_input_enqueue (mirroring bind_result_writer's
deferred-binding pattern) so the background-mode delivery tail landing in
Task 5 can later enqueue a settled child's result as steering input for a
live parent run. Wires the resolver's OnceLock field, the inherent and
trait-impl bind methods, and the composition-side bind call right after
host_input_queue is built. No AwaitEdgeSettler double exists outside the
resolver (rg -n "impl AwaitEdgeSettler" crates/ tests/), so there is no
second implementor to update. Structural only: no behavior change — the
bound port has no caller yet.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(turn-runner): background results append and enqueue per child

Adds AwaitEdgeResolver::deliver_background, the settle_and_maybe_drain
branch that routes SpawnSubagentMode::Background edges to it instead of
drain_settled_group (blocking mode is unchanged), and the resolver's
production HostInputEnqueuePort/LoopInput imports.

deliver_background walks the delivery chain end to end:

1. Append (idempotent): frame the child's final text (or failure summary)
   with FramedSubagentText::frame, accept it onto the parent thread via
   SessionThreadService::accept_subagent_result, and record the resulting
   message ref with AwaitEdgeStore::record_result_appended. A re-peeked
   edge that already carries appended_message_ref reuses it instead of
   accepting a second row (accept_subagent_result's own idempotency covers
   a mid-step crash).
2. Attend: query AgentTurnSpawnTreeRuntimePort::recent_runs_for_thread for
   the parent's newest run; a live, non-terminal record gets the settled
   result enqueued as LoopInput::SubagentSettled through the bound
   HostInputEnqueuePort, then AwaitEdgeStore::record_attention. No live
   run, an unbound port, or the enqueue itself refusing with
   RunClosed/CapacityExhausted/Disabled all leave the edge parked in
   ResultAppended and return Ok(Drained) rather than erroring — Task 6
   (2c) adds the parked-parent activation path.
3. Close only from AttentionScheduled, via AwaitEdgeStore::close.

Turn-runner runtime wiring (crates/loop/ironclaw_turn_runner/src/runtime.rs)
is deliberately NOT touched: parts.input_queue there is Option<Arc<dyn
HostInputQueue>> (the drain-reader half only), which does not implement
HostInputEnqueuePort, so there is no enqueue-capable handle to bind. The
resolver treats that unbound state as "no live queue" (the same
ResultAppended fall-through), not an error — composition's
bind_input_enqueue call (previous commit) covers the production path.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(turn-runner): parked parents are activated with system provenance

Task 6 (2c): replaces deliver_background's "parked-parent activation
lands here" fall-through with a real activate_parked_parent branch.
When a background child settles and its parent has no live run (or
the live-run enqueue itself refuses), the resolver now wakes the
parent through TurnCoordinator::activate with
ActivationProvenance::System, preserving the parent's own run profile
id. A streak-cap refusal parks the edge at AttentionDeferredStreakCap
(unclosed, excluded from autonomous retry); any other activation
refusal (ThreadBusy, transient Unavailable, ...) leaves the edge at
ResultAppended for the next drive to re-attend. Re-drive entry now
special-cases AttentionScheduled (close only) and
AttentionDeferredStreakCap (no-op) so a crash between activation and
close never triggers a second activate() call.

* refactor(turn-runner): move the await-edge resolver tests into their own file

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* refactor(processes): keyset paging on the dependency query

ProcessDependencyQuery gains after/limit fields (keyset cursor over the
existing canonical (dependent_process_id, dependency_process_id) sort
key). Both None reproduces the pre-existing unbounded query
byte-for-byte; a bounded request walks a new process_dependency_canonical_v1
index directly, applying filters before the cursor/limit bound, so a
bounded read stops once it collects `limit` matching rows instead of
draining the whole scope.

Adds the plumbing the run-start sweep needs without wiring it up yet:
AwaitEdgeSettler::sweep_thread_on_run_start (trait method + a real
resolver implementation, unreached by any production caller),
AwaitEdgeStore::list_background_for_thread, and a required
await_edge_settler field on RebornTurnRunExecutor (constructed
everywhere, not yet invoked from execute_claimed_run). No behavior
change for any existing caller.

* feat(turn-runner): run-start and boot sweeps heal background delivery

RebornTurnRunExecutor now calls AwaitEdgeSettler::sweep_thread_on_run_start
before invoke_driver on every claimed run, deriving human_initiated
from the claimed run's subagent_activation_provenance (absent/Human is
permitted; System/ParentAgent is not). The resolver's sweep walks the
thread's background dependency edges (bounded at
MAX_QUEUED_INPUTS_PER_RUN) and drives each through deliver_background's
existing idempotent re-drive: Settled/ResultAppended/AttentionScheduled
redeliver or close; AttentionDeferredStreakCap drains forward only when
human_initiated permits it (deliver_background gains a retry_deferred
parameter for this one caller — the reactive settle path keeps its
autonomous no-retry default). A sweep failure is logged and never fails
the run start.

boot_recovery's recover_scope replaces its ponytail no-op arms for the
background delivery substates: Settled(background)/ResultAppended
deliver through deliver_background (parked-parent activation included,
System provenance); AttentionScheduled closes only; a streak-capped
edge stays parked for a later permitted/human start. Blocking-mode
Settled keeps its pre-existing drain_settled_group path unchanged.

* test(integration): background delivery scenarios

Extend tests/integration/subagent_await_edge.rs with five scenarios
composing real DefaultTurnCoordinator + InMemorySessionThreadService +
InMemoryHostInputQueue + AwaitEdgeResolver over a shared in-memory
process journal (mirroring resolver/tests.rs's bg_fixture/SweepFixture
pattern with production components instead of test doubles):

- background_child_result_is_delivered_per_child_while_parent_runs
- run_closed_race_is_healed_by_activation
- parked_parent_is_activated_with_system_provenance
- background_delivery_replay_is_idempotent
- streak_capped_result_waits_for_human

tests/CLAUDE.md rows added in this same commit per its maintenance rule.
coverage-floor.toml: no recapture — this PR adds no production source to
any gated crate's denominator (test-only addition to the root
integration binary), so the file's own same-PR floor-raise trigger
condition does not apply.

* docs(subagent-spawn): R2 closeout — prompt wording and §9 prune

- Spawn capability description (crates/loop/ironclaw_loop_host/prompts/
  spawn_subagent_description.md, already a prompts/*.md file loaded via
  include_str!) gains background-mode wording: receipt semantics,
  per-child arrival, "do not poll". No Rust change needed — the
  descriptor already loads the file verbatim.
- Repoint every stale §-reference in await_edge/{mod,store,resolver}.rs
  and await_edge_port.rs doc comments off the deleted
  thread-harness-design.md onto docs/internal/reborn/subagent-spawn/
  README.md's own sections (boot_recovery.rs carries none). store.rs's
  existing §4.1/§4.2 citations already matched the README's numbering
  and are left as-is.
- README §2.5: fix the stale claim of "two lazy resolver paths
  (resolver.rs:1709, :1785)" — both were test-module lines; the only
  production recovery caller is subagent_spawn_port.rs's finish_spawn,
  confirmed by `rg -n check_scope_recovered`.
- README §9: pruned to a one-line "R2 shipped in PR nearai#7788" pointer;
  promoted R3 (gate escalation walk) into the pending slot per the
  section's own "pruned when R2 ships" instruction.

* fix(threads): scope the D14 finalized no-op to subagent-result rows

The D14 guard in `mark_message_submitted` checked `status == Finalized`
alone, so every finalized row — `Assistant`, `ToolResultReference`,
`CapabilityDisplayPreview` — returned Ok where it previously returned
`InvalidMessageTransition`. A caller aiming at the wrong message id was
masked instead of failing loud.

Subagent-result rows are written `MessageKind::System` by
`accept_subagent_result` in both backends, so the guard now requires that
kind; every other finalized kind falls through to `ensure_user_accepted`
and errors as before.

Extends `a_result_row_is_refused_by_the_steering_ladder` with the negative
half; it fails on both backends without the narrowing.

* fix(processes): fail loud on truncated pages, filter dependent_id in memory

Two defects in the bounded dependency query added by this branch.

`dependent_id` is the canonical index's sort key, not part of its equality
prefix. `ordered_query_prefix_values` requires the filter's equality-key
set to equal exactly the keys preceding the sort key (here
`lineage_scope_key` alone), so passing `dependent_process_id` as an
index-level equality filter made the ordered query Unsupported instead of
narrowing it. Latent today — no caller pairs `dependent_process_id:
Some(..)` with a `limit` — but armed for the next one. It now filters in
memory per page, like `group_ref`/`include_closed`.

A full page whose last row yields no cursor now returns Deserialization
rather than breaking out with a silent short read, matching the unbounded
sibling `query_indexed_collection`.

Adds libSQL parity coverage and the previously untested `limit == 0`,
`dependent_process_id: Some(..)`, and `include_closed: true` branches; the
dependent-filter bug surfaced from that coverage.

* docs(subagent-spawn): correct §2.1 and finish the §9 closeout

§2.1 "What ships today" still described the pre-slice-2b behavior — codec
rejects background via `background_subagents_disabled()`, schema hides
`mode`, `finish_spawn` hard-codes Blocking — all three now false. §9's
closeout sentence was truncated and claimed three slices while naming two.

Rewritten against live code, keeping the caveat that
`builtin.spawn_subagent` remains in `disabled_capability_ids` and is not
model-reachable until R9.

* fix(ci): repoint coverage exemptions after the resolver test move

f0c0b65 moved the await-edge resolver tests into their own file,
shrinking resolver.rs 2141 -> 1535 lines, but left two line-referenced
exemptions pointing at the old offsets. #38 (2032) fell past EOF and
failed the changed-coverage manifest validator; #55 (563) still resolved
and so silently exempted unrelated code.

Both statements verified present in each revision: the background gate-ref
arm moved 2032 -> 1427, and handle_child_terminal_inner's return type
563 -> 853. Scope, owner, and rationale are unchanged.

… consumer (nearai#7770 phase 1) (nearai#7765)

* feat(memory): periodic memory-curation pass ("dreaming"), first slice (nearai#7276)

Memory only ever grew. Writes accumulate, nothing prunes, and the standing
document has a byte budget, so redundancy crowds out what matters. No human
reads the file, so the decay is invisible.

This adds the Hermes-shaped answer: every N completed user turns, the agent
runs with no user present, re-reads its standing memory, and tidies it —
merging duplicates, resolving superseded facts, tightening wording. Its
output is the edits plus a structured report; nothing is sent to anyone.

Buildable now because unbound turns landed (nearai#7562/nearai#7634): a run with no
conversation and no reply target. The pass is submitted through the same
`UnboundTurnService` door OpenAI-compat and subagent spawn already use.

Shape. The loop tier owns only the observation ("an ordinary user turn
completed, under this scope") and reports it through a port; every policy
decision lives in the product tier. The port vocabulary sits in
`ironclaw_loop_contracts` rather than the runner because WS1.7 deliberately
removed `ironclaw_turn_runner` as a production dependency of
`ironclaw_assistant`, and this must not reverse that.

The load-bearing guard: an unbound run NEVER triggers curation. A pass is
itself unbound, so triggering on unbound completion would let each pass
schedule its successor — an unbounded background loop running the model
against a user's memory forever. Pinned by test, both unbound profiles.

Also fixed along the way: `UnboundTurnSubmission` had no way to declare
limits, so it always inherited the profile's 1024-iteration budget and no
wall clock. Fine for a user waiting on a panel, wrong for an unwatched
background chore — an unconverged pass would burn tokens against a user's
memory until that ceiling, and nobody would notice. Added narrowing-only
limits (existing callers unchanged, explicitly defaulted) and the pass
declares 6 model calls / 12 capability calls / 90s.

Safety properties pinned by tests: the pass acts as the owner and never as
an operator-config caller; it gets the three memory capabilities and nothing
else; its id doubles as the idempotency key so a crash-retry converges on
the same pass; a failed submission is swallowed at debug (post-terminal
background path — info!/warn! would corrupt the REPL).

Concurrency is safe without batch-atomic memory ops: memory writes are
compare-and-swap, so a pass racing a live conversation loses the write
rather than clobbering it. The failure mode is a lost curation pass, never
a lost memory.

Not wired into composition yet — no deployment runs this. Wiring, the
gate-behavior decision (unbound runs abort on approval gates, so users with
auto-approve off need skip-not-abort), and an integration scenario follow.

* fix(memory): avoid an extension name in curation comments

The extension-specificity gate scans generic code for concrete extension
names; "with slack for one retry" tripped it on the English word. Reworded
rather than allowlisted — the allowlist is for pre-existing debt, not for
new code that can simply say something else.

* refactor(memory): move the curation contract into ironclaw_memory

Memory vocabulary belongs with the memory contract. "Curation" means
nothing outside memory, and the signal exists only to decide whether a
user's memory needs tidying — putting it in ironclaw_loop_contracts made
the loop-contracts crate carry a memory concept it has no stake in.

Both tiers already depend on ironclaw_memory (the runner for after-turn
recording, the product tier for the memory service), so this pulls in no
new edge; it only puts the type where its domain lives.

* feat(hooks): add privileged AfterTurn lifecycle point

Adds `HookPointSpec::AfterTurn`, a privileged-only hook point that fires
once after a turn's run reaches a terminal state — the seam for work about
the turn as a whole rather than about one model call, capability
invocation, or checkpoint.

- `AfterTurnHookContext` (`points/turn.rs`) carries tenant/user/agent/
  project plus a `completed` flag. `user_id` is non-optional and there is
  deliberately no `unbound` field: the dispatch call site never fires this
  point for unbound runs, because hook-started background work runs
  unbound and firing on unbound completion would let each background pass
  schedule its own successor forever. Observing background runs stays with
  `EventTriggered` + `LoopCompleted`, which is observer-only.
- `PrivilegedAfterTurnHook` takes no sink: an AfterTurn hook may hold its
  own collaborators and start follow-on work as a side effect. The
  sealed-return-type law stays scoped to points untrusted tiers can reach.
- `install_after_turn` rejects `Installed` and `SelfAuthored` at install
  time; `install_observer` rejects the point outright.
- `dispatch_after_turn` mirrors the observer dispatch shape (ordered
  snapshot, poison handling, failure policy, telemetry) with a 5s per-hook
  timeout, and never propagates a hook failure to the caller.
- New `DecisionKind::Lifecycle` (three in-crate consumers, all updated):
  act-capable but fails isolated, since the run it observes is already
  terminal.

* refactor(memory): curation rides the AfterTurn hook point, bespoke port deleted

nearai#7765 landed memory curation on a bespoke `AfterTurnCurationPort` because no
general lifecycle seam existed yet. The `AfterTurn` hook point now exists, so
the port is deleted and curation becomes one privileged hook among others.

- `ironclaw_memory` sheds `src/curation.rs` entirely: memory carries no
  hook-framework vocabulary and no bespoke port.
- `ironclaw_turn_runner` gains `after_turn_hooks::after_turn_hook_context`,
  which keeps the two guards centrally so no hook has to remember them: an
  unbound run never fires the point (hook-started background work runs
  unbound, so firing on unbound completion would let each pass schedule its
  own successor forever), and an actorless run never fires it (nothing to
  attribute follow-on work to).
- The executor's `after_turn_curation` field becomes
  `after_turn_hooks: Option<Arc<HookDispatcher>>` with `with_after_turn_hooks`.
  The 5s bound survives as an OUTER backstop around the whole dispatch; the
  dispatcher already bounds each hook.
- Semantic widening: the point fires for ANY terminal state of an ordinary
  actor-bearing run, not just `Completed`. Hooks that only want successes read
  `ctx.completed` — which `MemoryCurationService` does, first thing, because a
  failed turn says nothing about whether memory needs tidying and counting it
  would drift the interval.
- `MemoryCurationService` implements `PrivilegedAfterTurnHook`; every policy
  decision (interval, per-owner counters, pass building, idempotency key)
  is unchanged. `ironclaw_assistant` takes a normal `ironclaw_hooks`
  dependency — products→loops, the edge it already has via `ironclaw_loop_host`.
- `AfterTurnHookContext::new` added: the struct is `#[non_exhaustive]` and the
  call site is outside `ironclaw_hooks`, so a struct literal is unavailable.

The dispatcher is un-wired (`None`) after this commit; composition follows.

* feat(memory): wire curation through composition behind [memory] config

Phase 1 of nearai#7770 ends where it should: the `AfterTurn` point has a live
consumer. Composition registers the memory-curation hook, so after every Nth
completed turn the agent goes off on its own and tidies the user's standing
memory document (nearai#7276).

- `[memory].curation_interval_turns` (`ironclaw_config`): opt-in, serde-default
  absent. Absent means the hook is NEVER REGISTERED — disabled is expressed by
  not wiring, never by a sentinel, so a written `0` is rejected at parse time
  rather than clamped downstream into "after every turn". Config-only, no env
  override: that matches `provider`/`admin_overrides`, and only the mem0
  connection fields carry an env convention.
- `ironclaw_assistant::memory_curation::after_turn_curation_dispatcher` owns the
  assembly — which hook, at which phase (`Telemetry`: the run is already
  terminal, so it enforces nothing), under which trust class (`Builtin`), behind
  the stable `HookId::for_builtin` path. Composition calls it; per AGENTS.md the
  wiring root does not own module policy. Its own small dispatcher, not the
  per-run middleware one: `after_turn` fires once per run from a
  process-lifetime `Arc`.
- `DefaultPlannedRuntimeParts::after_turn_hook_dispatcher_factory` is a factory,
  not a ready dispatcher, because the `UnboundTurnService` the hook submits
  through is built from the coordinator the same function builds. Handed
  `AfterTurnHookDeps` once, after those exist; may still decline.
- Two conditions gate registration in composition: an operator asked for an
  interval AND a memory provider resolved. A pass over a document no provider
  backs would submit a run whose only three tools do not exist.

Gate posture (nearai#7770's skip-and-note) is deliberately NOT implemented; a
`DECISION nearai#7770:` comment at the submission site records why. No read-only
"would this capability gate for this scope" query exists: the answer needs the
descriptor's effects and origin-gate matrix, the run's `ApprovalPolicy`, the
`TrustDecision`, grants, and leases composed inside
`authorize_dispatch_with_trust` at dispatch time, with an origin that does not
exist until the run is executing. Approximating it from
`ApprovalSettingsProvider::global_auto_approve` alone would duplicate gate
composition in a product service. The seam that is actually missing is at the
gate strategy: a `GateOutcome` that skips the capability for the model instead
of aborting the unbound run.

Tests: two group scenarios drive the wired path end to end — the pass's thread
id is its idempotency key and therefore deterministic, which is what lets the
harness script the background pass's model at all. The positive scenario runs N
ordinary turns and asserts the tidied text reaches a LATER conversation's prompt
under the same user's own memory lane; the negative asserts an empty pass script
below the interval and then corroborates it by crossing the interval one turn
later, so "empty" cannot be latency. Both falsified by moving the interval.
`with_memory_curation_interval()` on the group builder mirrors production's
opt-in exactly; the wiring-parity tripwire and composition mass gate move with
the new field.

* fix(memory): review round — per-trigger pass identity, conversation-only triggers, fail-closed install

Six review findings on nearai#7765 (epic nearai#7770 phase 1).

- **Pass identity was the number of OWNERS, not passes.** The curation pass id
  was `…-{counters.len()}`, which for one user is forever `1`: every interval
  after the first reused the same public id and idempotency key, so the unbound
  accept door REPLAYED the first pass instead of running a new one — the
  document would be curated exactly once, ever, with nothing surfacing it.
  `AfterTurnHookContext` now carries `run_id` (the terminal run that fired the
  point), the runner threads it through, and the pass id is
  `memory-curation-{tenant}-{user}-{run_id}`: distinct per trigger, and
  replayed as-is by a crash-retry of the same trigger, with no durable counter.
- **Scheduled-trigger fires and subagent children no longer count.** A trusted
  fire keeps its creator as `TurnActor` and runs a non-unbound profile, so it
  passed both original guards and could launch a write-capable pass with no
  user present. The derivation is now an ALLOWLIST of conversation profiles
  (`reborn-planned-default`, `interactive_default`, `default`); the
  denylist shape failed open for every profile added later.
- **Curation install fails closed.** `AfterTurnHookDispatcherFactory` returns
  `Result` and the runtime build propagates it as
  `DefaultPlannedRuntimeBuildError::AfterTurnHooks`. Declining is expressed by
  supplying no factory, never by a swallowed error that leaves a deployment
  believing memory is being tidied.
- **A zero interval is unrepresentable downstream.** Config already rejected
  `curation_interval_turns = 0`; `NonZeroU32` now carries through the input
  builder into `MemoryCurationService`, and the clamp is gone.
- **Typed error and typed counter key.** `CurationPassSubmitter::submit_pass`
  returns `UnboundTurnError`; counters key on a `(TenantId, UserId)` struct.
- `// arch-exempt:` on the executor's hook field uses the enforced
  `plan #NNNN` form.

Tests: distinct-vs-converging pass ids; scheduled-trigger and subagent profiles
yield no context, planned-default does; the executor actually dispatches at the
seam (recording hook over a completed bound run, and never for an unbound one);
`accept_and_submit` journals the declared `TurnLimits`. The two curation
scenarios script the pass by owner-scoped thread PREFIX — a new test-support
`register_scope_script_prefix_for_test` — because a per-run pass id is not
knowable before the triggering turn runs.

* fix(ci): panic-free interval const + QA harness field the sweep missed

Two breaks, one class: struct call sites in test bins the local
verification set never compiled.

- The production panic baseline scans syntactically, so the compile-time
  `match … unreachable!()` NonZeroU32 constructor counted as a new panic.
  Replaced with `NonZeroU32::MIN.saturating_add(9)` — const, panic-free,
  and the comment says why the odd spelling exists.
- `reborn_parity_qa/binary_e2e.rs` initializes DefaultPlannedRuntimeParts
  and needed the new `after_turn_hook_dispatcher_factory` field (None: QA
  replay drives no lifecycle hooks).

Verified with `cargo check --workspace --tests` — the command that
covers every bin, which the per-crate verification lists did not.

* fix(filesystem): satisfy the Rust 1.98 chunks_exact_to_as_chunks lint

Rust stable 1.98 rolled through CI today and its new clippy lint fails
every branch on decode_embedding_blob's chunks_exact. as_chunks is the

per-element indexing disappears. Behavior pinned by the existing vector

Full-workspace sweep under 1.98 (the toolchain CI now runs), on top of the

  (one variant, nine sites' worth of warnings); agent_loop's batch error
  boxes its host error; turn_runner boxes only HostFinalizationFailed's
  payload — DriverError stays unboxed because five match sites destructure
  it by pattern, and it is not the oversized member.
- chunks_exact_to_as_chunks: the two UTF-16 decoders in coding/text.rs.
- useless_format in a trace_commons test.

All private types or contained call sites; no public API changes beyond
the boxed variant payloads inside their own crates.

* docs(hooks): Lifecycle-vs-Effect rationale + amend the side-effect invariant

Approach-audit disposition on nearai#7770 (accepted findings ST3/SP3):

- trust.rs documents why Lifecycle is not a duplicate of Effect: Effect is
  permitted for Installed/SelfAuthored by default — the third-party class
  for post-durable-fact event hooks — while turn completion must not carry
  that default. Folding them would silently widen who may react to a
  finished turn.
- The hooks contract's side-effect invariant now names mediated
  prepared-context turn submission as a sanctioned route for Lifecycle
  hooks, instead of the code silently diverging from a list written before
  unbound turns existed.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(memory): audit round 2 — fail-closed curation gate, per-run hook dispatcher

Second approach audit on nearai#7765 (nearai#7770 phase 1). Six accepted findings plus
the documentation gaps they exposed.

Fail closed on a provider that cannot curate. Composition registered curation
whenever an interval was configured and any memory provider resolved, but a
pass REPLACES the standing document and a bound third-party provider may
reject that write outright — a deployment would spawn passes forever that all
fail, with nothing surfacing it. `curation_interval_for_binding` now gates on
the resolved binding and turns a configured-but-unservable curation into a
startup error naming the provider and how to disable it. Nothing in a manifest
declares "supports standing-document replacement" (`[memory].lifecycle` is
about read/record hooks), so the gate is the native binding, with the missing
declaration named in the comment as the seam for nearai#7664.

Hook poison is run-scoped by contract, so the executor now holds a per-run
dispatcher FACTORY instead of one process-lifetime dispatcher: a panic or
timeout is barred for the run it happened in and retried on the next, instead
of disabling curation until restart. The curation SERVICE stays one long-lived
instance — its per-owner counters must accumulate across runs — and each fresh
dispatcher installs a binding over that same service.

Blocked states no longer dispatch. `after_turn_hook_context` requires
`TurnStatus::is_terminal()`: a gated-then-resumed turn fired the point twice,
once while still running.

Also: tier-specific `install_builtin_after_turn` / `install_trusted_after_turn`
replace the trust-class-parameterized installer (an invalid tier is now
unrepresentable, not rejected at runtime); the executor's outer dispatch bound
moves 5s -> 30s so it can never preempt the dispatcher's own per-hook timeout
classification; the unused default-interval constant is deleted and its "ten
matches Hermes" rationale moved to the config field a deployer reads; the
hooks consumer inventory gains `ironclaw_assistant`; and `points/turn.rs` now
states plainly that the point fires only for exits the executor applies —
scheduler failure terminalization does not dispatch it, tracked as a follow-up
on nearai#7770.

Composition budget 42198 -> 42316 (both records, dated): +7 wiring, +109 for
the fail-closed gate and its tests.

* fix(hooks): enforce the after_turn tier gate in the registry, and close the review gaps

CodeRabbit round three on nearai#7765.

`HookRegistry::insert` now refuses `Installed` / `SelfAuthored` bindings at
`HookPointSpec::AfterTurn`, alongside the phase-vs-trust gate it already
carries. The tier-split installers encoded the restriction, but raw bindings
reach the registry through `from_bindings` and the public builder's
`insert_binding`, which bypass them — the point is act-capable, so an
untrusted binding there would surface as a malformed binding mid-dispatch
instead of an install-time refusal.

The dispatcher's per-hook `after_turn` budget becomes injectable
(`HookDispatcherBuilder::with_after_turn_timeout`, defaulting to
`AFTER_TURN_HOOK_TIMEOUT`), which is what makes the timeout-race regression
affordable: the executor-seam test wedges one hook against a millisecond
budget and proves the hook ordered after it still runs, that the wedged one is
recorded as a Timeout failure, and that the already-terminal run is unaffected.
That asymmetry — outer backstop strictly larger than per-hook budget times hook
count — was fixed earlier but never pinned.

Executor-seam coverage also gains the two non-success terminal states: a FAILED
and a CANCELLED conversation run each dispatch exactly once with
`ctx.completed == false`.

The below-threshold curation scenario no longer rests on a single empty
reading, which a queued-but-unstarted pass would also produce. After crossing
the interval it now requires EXACTLY ONE pass — one pass's worth of model calls
and no more — which is what makes the earlier zero real rather than latency.

The group harness mirrors production's two-part activation gate: curation wires

interval alone.

* chore(composition): re-measure the mass budget after the main merge

The merge combined main's composition growth (notification inbox nearai#7697,
subagent slice nearai#7788) with this branch's curation wiring; the two
ceilings merged textually without a git conflict while the sum exceeded
both — the gate caught exactly the case it exists for. Ceiling and the
mirrored COMPOSITION_ABSOLUTE_SRC_LOC move together to the measured
42479, dated rationale in the toml. No composition code changes here.

* fix(memory): give the curation pass report headroom — live-test finding

The 2026-08-21 live test (DeepSeek-V4-Flash, isolated home, interval 2)
proved the machinery end to end — the pass fired exactly once, acted as
the user, consolidated two wordings of one fact into a correct merged
line, and read its own write back to verify — and then terminated
`Failed { model_call_limit }` before emitting its structured report. A
real model spends calls a scripted one does not: three writes where the
prompt asks for one, plus a fumbled read.

Two changes, both evidence-backed:
- MEMORY_CURATION_MAX_ITERATIONS 6 -> 10. The ceiling still hard-stops
  an unconverged pass; it now leaves room for the report after ordinary
  real-model imperfection.
- The prompt's Finishing section states the budget and the exact
  sequence (read -> at most one write -> result tool), and says plainly
  that a pass dying unreported is worse than a pass changing nothing.

The scripted integration scenario hands the model exactly three replies
and structurally cannot see this failure mode; the constants comment
records the live evidence so the next tuner knows where 10 came from.

* feat(extension-contracts): declare [[memory.scheduled_ops]] — pass ops, trust-gated, cost-floored

A memory provider can now declare its own recurring upkeep in its manifest
instead of the host hardcoding which provider gets which background work.
The provider names the work and the cadence; the host keeps the clock, the
invocation envelope, and the authority.

    [[memory.scheduled_ops]]
    trigger = "after_turn"
    interval_turns = 10
    pass = { prompt = "prompts/memory_curation.md", tools = ["ironclaw.memory.read", "ironclaw.memory.write"], max_model_calls = 10 }

Contracts tier only — nothing dispatches or invokes these yet.

`MemoryScheduledTrigger` is a closed host-owned vocabulary with exactly one
v0 entry; an unrecognized token fails the parse rather than being dropped,
because a silently ignored trigger presents as a provider whose declared
upkeep simply never runs. `MemoryScheduledOpKind` is tagged by which key the
entry declares, and `tool = "..."` is RECOGNIZED and REJECTED with its own
message rather than falling through to an unknown-field error, so a manifest
written against the eventual schema fails with intent. Both keys or neither
are errors too. The wire shape and the parsed shape are separate types, so
`MemoryScheduledOp` cannot be built from a manifest without clearing every
per-op rule.

Three bounds, each with its reason in a doc comment and a test:

- `interval_turns >= 2` (`MIN_SCHEDULED_OP_INTERVAL_TURNS`) — a manifest
  declares work that runs on someone else's deployment at their expense, so
  it must not be able to demand per-turn invocation. `NonZeroU32` makes
  "every 0 turns" unrepresentable before the floor even applies.
- `pass.max_model_calls <= 16` (`MAX_SCHEDULED_PASS_MODEL_CALLS`) — a pass is
  unwatched background spend with nobody reading the transcript. The nearai#7770
  live test put the realistic curation need at 10.
- At most one op per trigger — the host holds one interval counter per
  trigger per owner, so a second op has no well-defined cadence.

Two rules need the whole manifest and land in
`ironclaw_extension_registry::v3::validate_memory_scheduled_ops`, beside the
existing `[admin_configuration]` cross-check and for the same reason — only
that layer sees `[[tools]]` and the requested trust class next to `[memory]`:

- A pass's `tools` must be ids the SAME manifest declares. Declaration is
  selection, never authority: a memory provider must not schedule passes
  wielding another extension's tools.
- Only a first-party/system manifest may declare a pass op at all. A pass is
  a manifest-authored prompt running with write tools, as every user, on a
  schedule — a strictly larger grant than a model-chosen tool call, so it
  gets the same default-deny wall as the after-turn hook tiers. Host-bundled
  alone is not enough, pinned by a test that refuses a third-party-trust
  manifest from a host-bundled source.

`scheduled_ops` is serde-defaulted and empty when absent, so every manifest
written before it existed parses unchanged and schedules nothing
(`memory_manifest_without_scheduled_ops_still_parses`,
`scheduled_ops_absent_in_an_older_manifest_means_none`). `pass.prompt` reuses
`guidance_doc`'s validated bundled-asset ref type; asset RESOLUTION stays
host-side and fail-closed.

The §11.2.3 contracts size ceiling moves 10_841 -> 11_451 for the declaration
family and its inline tests, count read from the ratchet's own failure
message.

* feat(memory): scheduled ops drive curation — native declares its pass, opt-in stays

The declaration replaces the hardwired layer (nearai#7664 addendum v2):

- memory-native's manifest declares its curation as `[[memory.scheduled_ops]]`
  (after_turn, recommended cadence 10, pass over its own three memory tools,
  max_model_calls 10 — the live-test calibration). The curation prompt moves
  into the package beside the guidance doc, exported through the same asset
  table, resolved host-side fail-closed.
- `MemoryCurationService` dies; `MemoryScheduledOpRunner` is built FROM the
  resolved declaration (prompt text, tool ids, model-call ceiling), keeping
  the policy that was already pinned: per-owner counters, completed-only
  counting, the `memory-curation-` pass-id prefix as contract, the submitter
  seam, debug-only failure swallowing. The tool-op arm is
  unreachable-by-construction (leg A parse-rejects it) and says so explicitly.
- Composition's native-only gate arm dies: the gate is now "did the bound
  provider declare an op" — a configured interval against a provider that
  declares nothing stays a startup error naming the provider.

OPT-IN preserved (owner decision, 2026-08-22): the declaration ARMS upkeep —
validated shape, resolved prompt, recommended cadence — and
`[memory].curation_interval_turns` ENABLES it. Omitted = nothing runs,
exactly as before this change; a manifest cannot switch on background token
spend for a deployment that never asked. The config floor (>= 2) is now
enforced at parse, where the operator can read why.

Leg B built by a subagent (session-limited mid-flight), completed and
re-verified from the worktree; opt-in flip + config validation + marker
resolution by the orchestrator.

* fix(memory): the curation prompt demands an explicit append:false — live-test v2 finding

The declared-op live re-test (2026-08-23, DeepSeek-V4-Flash, fresh isolated
home): the pass reached its structured report — the model_call_limit death
from the first live test is fixed — but the model's FIRST write omitted
append:false, transiently duplicating the document before it self-corrected
with a proper replace two calls later. The prompt asked for one write; it
never said which KIND. Now it does, with the consequence spelled out.

* feat(loop-contracts): typed subagent-settled loop input

Add LoopInput::SubagentSettled { child_run_id: TurnRunId, message_ref:
LoopMessageRef } — refs only, no child content (D4). Inert surface: nothing
constructs this variant outside tests in this slice; Task 2 wires production
use.

Widened the existing ironclaw_host_api::turn import in input.rs to include
TurnRunId rather than adding a second import path.

cargo check --workspace after adding the variant reported exactly one
non-exhaustive-match site: crates/loop/ironclaw_agent_loop/src/executor/input.rs:188
(consume_drainable_inputs). Added SubagentSettled to that barrier arm
(break, same as GateResolved/CapabilitySurfaceChanged) as a deliberately
temporary placement — Task 2 moves it into the drainable arms.

Establishes the first serde tests for LoopInput: a round-trip test pinning
the snake_case tag, and a historical-wire-forms test guarding the durable
run-queue document (durable_input_queue.rs:109), where a parse failure
corrupts the whole queue rather than one entry.

* feat(agent-loop): drain subagent-settled inputs steering-like

SubagentSettled now drains like UserMessage/Steering in the Steering
mode and additionally in FollowUp mode, matching the rationale already
documented for Steering-during-final-call. Removing it from the
control-barrier arm required adding it to the exhaustive match's
drainable-variant arm in consume_drainable_inputs so the match stays
exhaustive (that arm is unreachable at runtime for it since both drain
modes now catch it first).

* fix(agent-loop): correct reachability comment for the drain fall-through match

The prior comment claimed FollowUp was unreachable in the fall-through
match, but Steering mode does not drain FollowUp inputs, so a
FollowUp-variant input genuinely reaches that arm (and breaks, left
unconsumed) when draining in Steering mode. Narrow the comment to what
is actually unreachable: UserMessage, Steering, and SubagentSettled,
which both mode arms drain. Also aligns the Steering arm's brace style
with the structurally parallel FollowUp arm (cosmetic only).

No control-flow change.

* refactor(agent-loop): delete the dead background-drain stub

PostCapabilityStage::drain_settled() has been dead since it was scaffolded:
it always returned an empty Vec, its single call site bound the result to
_drained and never read it, and its doc comment promised a
LoopBackgroundChildPort that exists nowhere in the repository. The real
settled-background-subagent delivery path is LoopInput::SubagentSettled
(tasks 1-2 of this slice). Remove the fn, its call site, and the stale R2
doc paragraph; renumber the surviving R1 compaction doc to plain prose
since the R1/R2 split no longer exists.

Structural only — no behavior change. Verified drain_settled and
LoopBackgroundChildPort are referenced nowhere else in crates/ or tests/
(word-boundary grep), and cargo test -p ironclaw_agent_loop --no-fail-fast
is green (565 tests, 0 failed).

* feat(processes): dependency delivery substates and expected-state transition

Delivering a settled dependency's result to its dependent is three durable
facts, not one, and a crash can land between any two of them. Give the
kernel dependency state machine the three in-flight states that sit between
`Settled` and closure — `ResultAppended`, `AttentionScheduled`,
`AttentionDeferred` — plus one expected-state compare-and-swap
(`ProcessDependencyPort::transition_process_dependency`) that advances the
state column only when it still holds the state the caller expects, so a
half-applied step can be replayed without double-applying the next one.

The names stay kernel-neutral: the state column says what happened to the
edge, not which product feature produced it. Keeping all three on the column
(rather than one of them in metadata) keeps any projection over these rows a
total function of the state column.

Inert surface: nothing outside the contract tests calls the new operation or
writes the new states in this slice.

Persistence notes:
- The enum is serialized verbatim into journal rows with no tolerant-reader
  fallback, so the four historical spellings are pinned by a test and the
  three new ones are pinned as durable format too.
- `ProcessDependencyRecord` gains `transitioned_at`, `#[serde(default)]` and
  skipped when absent, so historical rows still decode.
- All three new states are in-flight: the persisted `closed` index and both
  query predicates derive closedness from `Consumed | Abandoned` alone, so
  the new states index as open and stay visible to the host recovery scan —
  asserted through the real index, not just the in-memory filter.

The loop-tier await-edge projection had an exhaustive match over the enum;
its three new arms fold onto `AwaitEdgeState::Settled` (marked `ponytail:`)
until the slice that walks the delivery chain gives it real arms.

* fix(processes): keep dependency closure on the one journal command that releases the reservation

Two holes in the delivery state machine added by the previous commit, both
found in self-review and both closed here.

The expected-state CAS could write `Consumed`/`Abandoned` into the state
column. It writes that column and nothing else, so that was a second door to
a terminal state that skipped `release_dependency_reservation` — precisely
the compensating dual write this crate's AGENTS.md forbids, and it would
have leaked one descendant slot per closed edge forever. Both terminal
targets are now refused up front, before the record lookup and before any
mutation, with a reason naming the operation that closes the edge and
releases the reservation in the same journal command. Refusing before the
expected-state check keeps the answer deterministic: reaching for the wrong
door gets the same error whatever the stored state is.

`consume_process_dependency` required exactly `Settled`, which made
`AttentionScheduled` a state an edge could enter and never leave. It now
accepts `Settled | AttentionScheduled`, and deliberately no further:
`ResultAppended` has no attention recorded yet, and `AttentionDeferred` is
parked on purpose so an unclosed-query sweep can still find it. Closing
either would strand the dependent with a result it never looks at. Abandon
is unchanged — a parent that gives up mid-delivery must still return tree
capacity from any non-terminal state.

The state machine is now closed under its own rules: every state the CAS can
reach has an exit, and every path to a terminal state releases the
reservation atomically.

The wrong-expected-state test targeted `Consumed`, which the new guard makes
unconditionally illegal; it would have started passing for the wrong reason,
so it now targets a legal state and still tests only the expectation
mismatch.

Still inert: nothing outside the contract tests calls the transition
operation or writes a delivery substate.

* feat(turn-runner): project delivery substates onto the await edge

Task 4 added three in-flight delivery states to the kernel's
`ProcessDependencyState` and left `AwaitEdgeStore::edge_from_record`
collapsing all of them onto `AwaitEdgeState::Settled` behind a `ponytail:`
marker, because the loop-tier enum had no arms for them. Give it the arms
and retire the marker.

- `AwaitEdgeState` gains `ResultAppended`, `AttentionScheduled`, and
  `AttentionDeferredStreakCap`. The kernel's `AttentionDeferred` stays
  domain-neutral; the loop tier is the layer that knows what a streak cap
  is, so the names differ on purpose.
- `AwaitEdge` gains `appended_message_ref` and `attention_outcome`, both
  optional and skipped when absent, plus the `AttentionOutcome` enum.
- Three store methods walk the chain over the kernel's expected-state CAS:
  `record_result_appended` (Settled -> ResultAppended, carrying the
  parent-thread message ref), `record_attention` (-> AttentionScheduled),
  and `defer_streak_capped` (-> AttentionDeferred). Their metadata is
  *merged* into the record's blob, which is the serialized edge itself.
- `close` consumes only `Settled | AttentionScheduled` — the two states the
  kernel will close — and leaves the in-flight ones parked, matching the
  journal's refusal to strand an undelivered result. Closing still goes
  through `consume`, never the state-column CAS.
- `reservation_release` is unchanged: `Released` for `Consumed | Abandoned`
  only. All three new states are in flight and stay `Unclaimed`.

The projection matches remain exhaustive with no wildcard — that
exhaustiveness is what surfaced this site in the first place. Boot recovery
gains explicit no-op arms with a `ponytail:` naming the sweep that lands
with the producer; nothing outside tests writes these states in this slice.

* test(turn-runner): pin that the delivery chain refuses to skip the append

`record_attention` targets `AttentionScheduled` with `ResultAppended` as its
expected state, so scheduling attention before the child's result is durably
appended is refused by the kernel's expected-state CAS. Nothing pinned that
ordering: widening `record_attention`'s expected state to `Settled` left the
whole suite green except the lifecycle walk, which failed for the unrelated
reason that its second step no longer matched.

Pin it directly — the refusal surfaces as an error carrying the kernel's
cause, and the refused transition leaves the edge exactly where it was.
Covers `AttentionOutcome::Activated`, which the lifecycle walk does not reach.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(turn-runner): give a streak-capped await edge a way out

`AttentionDeferredStreakCap` was a dead end. `record_attention` hard-coded
`ResultAppended` as its expected state and the kernel's `consume` takes only
`Settled | AttentionScheduled`, so a parked edge had no forward path and no
closing path — it could only be abandoned. That contradicts design §4.1/§4.2,
where a streak-capped edge stays unclosed "until a permitted or human-initiated
run start drains it": draining *is* scheduling attention.

`record_attention` now advances from either legal predecessor. The kernel CAS
takes one expected state, so the store reads which of the two the edge stands
on and hands that observation back as the expectation. The guard is intact:
the expectation is still asserted against stored state inside the journal
command, so a concurrent writer that moved the row in between makes this write
lose. An edge on neither legal predecessor falls through to `ResultAppended`
and is refused by that same check — this is a two-element legal set, not
"advance from anywhere", and the kernel CAS contract is unchanged.

Tests: the deferred branch is now proven closeable end to end — parked, `close`
a no-op while parked, drained forward by attention (keeping the already-appended
message ref), then consumed with no dependency left unresolved. Also pinned that
replaying attention keeps the first outcome.

`the_delivery_chain_refuses_to_skip_the_append` from 9b8071d was written to
catch a naive widening of this expected state to `Settled`; it stays green
before and after this change, which is the evidence that one specific door
opened rather than the guard loosening. A near-identical refusal test I had
written separately was dropped in favour of that pin, with its one extra
assertion folded in.

* fix(turn-runner): recover appended_message_ref/attention_outcome from the real production blob

edge_from_record's fallback branch hardcoded appended_message_ref: None and
attention_outcome: None, on the assumption that the fallback (AwaitedChildSetRecord)
shape was a legacy path. It is not: subagent_spawn_port.rs is the sole production
writer of dependency metadata and it always writes that shape, so
from_value::<AwaitEdge> always fails against real data and the fallback always
fires. The delivery-chain CAS merges appended_message_ref/attention_outcome into
that same blob as sibling top-level keys (additive merge, never a replace), so the
durable blob carries both fields — the fallback just never read them back,
discarding them on every projection and breaking the documented replay-safety of
record_result_appended/record_attention against real production data.

Existing tests missed this because settled_background_edge opened its fixture
dependency with a full AwaitEdge-shaped blob (serde_json::to_value(&edge)), which
production never writes and which takes the primary parse branch instead of the
fallback. Switched that fixture (and legacy_edge_metadata_fallback_and_malformed_metadata_fail_closed,
via a new shared awaited_child_set_record() helper) to the real
AwaitedChildSetRecord shape, which is what exposed the bug: four tests went red
with the fallback hardcoded to None, confirming the finding.

Also: renamed record_attention's shadowed `outcome` local to `outcome_value`, and
corrected two module-doc clauses in mod.rs — abandon reaches any non-terminal
state (the kernel's close-dependency guard only gates consume), and
AttentionDeferredStreakCap is not consumable from here but is still abandonable.

* feat(threads): idempotent system-class subagent-result acceptance

Adds `SessionThreadService::accept_subagent_result` — the durable door a
background child's framed result enters the *parent's* thread through,
exactly once across a crash-and-replay.

- The row is `MessageKind::System` / `MessageStatus::Finalized`, never
  `MessageKind::User`: a child's output is untrusted agent text, not a
  human instruction on the steering contract.
- Dedupe reuses the ONE existing acceptance index — the flat SHA-256 of
  `(scope, source_binding_id, external_event_id)` that `accept_inbound_message`
  already writes — rather than adding a second one. Both halves of the
  identity arrive as caller-supplied strings; this crate cannot see run
  identity (no `ironclaw_processes` edge) and derives nothing.
- Two-phase claim on backends without transactions: the idempotency record
  is written before the row, so a crash in between leaves a durable recovery
  intent and the retry resumes the SAME message id instead of appending the
  result twice. A retry whose payload disagrees with the claim fails closed
  on a content-free fingerprint.
- `IdempotencyState` is the former `InboundIdempotencyState` made generic in
  the accepted-reply shape so both doors share one classification; the large
  `Pending` payload is boxed.

The trait method carries a fail-closed default (house convention, nearai#7752), so
the 11 test doubles stay at zero diff — and the `Arc<S>` blanket forward is
added, because a forgotten forward inherits that default silently. Both
production backends implement it for real.

Nothing calls it: this slice lands inert surface only.

* docs(subagent): correct the R2 design record against live code

Recon against live code found four categories of false or stale claims in
the canonical subagent design record: an overclaimed in-memory queue with
no compat concern (production is filesystem-backed and deserializes the
queue document whole), an overclaimed GateResolved precedent (zero
producers, treated as a barrier — SubagentSettled is the first host-side
settlement input), four wrong file paths/scopes in the Part II task list,
and two undocumented decisions (three kernel substates instead of two, and
the 2a/2b/2c slice split). Also marks the inert surface slice 2a already
shipped and records two open items found during 2a and left for 2b.

* test(threads): pin that subagent-result acceptance fails closed on an unknown thread

A child's framed result may only land in a thread that already exists under
the caller's scope. The door must not conjure a thread — and because it claims
the acceptance identity BEFORE the row on backends without transactions, a
rejected acceptance must not burn the identity: the retry has to be rejected
again rather than come back reporting an idempotent replay of a row that was
never written.

Covers both production backends behind `Arc<dyn SessionThreadService>`.

* docs(subagent-spawn): fix stale two-variant enumeration and freshness date

Task 5's Files bullet still named only ResultAppended and

decision. Name all three and point at D12. Also bump the "Last
verified against code" date to 2026-08-21 to match the latest
verification pass.

* test(threads): cover the orphan-claim window on the unknown-thread reject

`subagent_result_into_an_unknown_thread_fails_closed` documents a
non-transactional-backend property it never reaches: both backends it runs on
either commit the identity claim with the row or never write one, so neither
enters the state the comment describes.

Refusing `BeginTxn` forces the two-phase fallback. The recorded backend traffic
confirms the window is real — claim `WriteFile` lands at the idempotency path,
then the thread `ReadFile` misses — leaving a durable claim pointing at a row
that will never exist. The retry must still be rejected: an orphan claim must
never be mistaken for a committed row and replayed back as an accepted result.

The property is defended twice (the classifier verifies the thread before
reading the message, and a missing row resumes rather than replays), so the
test only goes red when both guards are removed — verified by mutation, with
the two pre-existing unknown-thread cases staying green throughout.

* refactor(threads): one two-phase claim-then-row protocol for both acceptance doors

`accept_subagent_result`'s `TransactionalMessageWrite::Unsupported` arm was a
second copy of `accept_inbound_message_with_replay_metadata`'s: the same
`CasExpectation::Absent` claim before the row, the same `VersionMismatch`
re-classify-and-resume recovery, the same `reserve_sequence` ->
`write_new_message` -> resume-race read. Only the classifier, the reply shape,
and the diagnostic strings differed — and the two had already drifted apart on
day one.

Lifts that arm into `write_new_message_claiming_identity_first`, parameterized
by a `FallbackAppend` describing where the row lands and which identity claim
guards it, plus the door's `classify` closure returning `IdempotencyState<T>`.
Both doors now call it. The crash window that stops a message being appended
twice is closed in exactly one place, so a fix to it can no longer reach only
whichever copy a bug report names.

No behavior change on any covered path:
- The inbound resume-race read moves from `accepted_message_from_idempotency_path`
  to `idempotency_record_from_path` + `classify`. Both yield `Accepted` under
  exactly the same condition (the row exists and the actor matches); every
  other outcome falls through to the original write error as before.
- The subagent resume-race read moves from a bare `read_message_versioned` to
  the same `classify_subagent_idempotency_record` the rest of that function
  already uses, which additionally rejects a thread mismatch or a non-system
  row. Identical on the happy path, strictly fail-closed on the mismatch.
- Claim-conflict diagnostics are now built from the door's write label.

Regression net (all green, unchanged): `filesystem_fallback_idempotency_failure_precedes_message_persistence`,
`filesystem_fallback_resumes_intent_with_original_model_after_message_failure`,
`filesystem_fallback_accept_concurrent_duplicate_replays_existing_message`,
`filesystem_transactional_accept_concurrent_duplicate_replays_existing_message`.

Drops the `ponytail:` marker that named this duplication as accepted debt — the
debt is paid, and a marker for debt that no longer exists is its own defect.

* feat(threads): refuse a subagent-result identity with an empty half

`("", "")` hashes to a perfectly valid dedupe-record key. A producer that
forgot to populate `external_event_id` would therefore collapse every child of
every parent onto one row and get `idempotent_replay: true` back for all of
them — a fail-OPEN shape in the one door whose entire job is fail-closed
dedupe, and one that looks like success at every call site.

Both halves are now validated (non-empty after trim) before the identity is
hashed, on both backends, via one `validate_subagent_acceptance_identity`
beside the existing `validate_attachment_refs`. Rejection is typed:
`SessionThreadError::InvalidSubagentResult` — a caller error, following
`InvalidPreparedContext`, never `Backend`.

Also pins two promises that had no in-tree proof:

- `a_backend_without_the_door_fails_closed` drives the trait's fail-closed
  default through a backend that implements every REQUIRED method and
  overrides nothing else — the exact shape of the 11 test doubles this slice
  left at zero diff. Without it the default's correctness rested on
  uncommitted mutation evidence.
- `filesystem_fallback_unknown_thread_claim_is_not_replayed_as_accepted` now
  asserts the burned identity HEALS once its thread exists. The rejection
  assertions alone were not load-bearing: an orphan claim read as a committed
  row still surfaces `UnknownThread` on the retry from a later stage, so the
  test passed against that exact bug. Verified by mutation — making a
  row-less claim classify as `Accepted` now fails this test.

* fix(processes): make a new terminal dependency variant fail to compile

`apply_transition_dependency` refuses to let the state-column CAS close a
dependency edge, because closing and releasing the descendant reservation are
one journal command (crate AGENTS.md:40). The refusal matched `Consumed` and
`Abandoned` and swept everything else into a `_ => None` wildcard.

That wildcard is fail-open on an enum this branch just proved gains variants
(it gained three). A future terminal variant would fall through it, get written
by the CAS, and permanently leak the descendant reservation slot: rows.rs:1563
indexes the row as closed, `apply_close_dependency` returns early as
already-terminal, and nothing ever releases the reservation. Silent, permanent,
no compile error.

Enumerate the five non-terminal variants instead. Adding a terminal variant now
fails to compile in the one file that owns the paired release.

* test(threads): pin that both acceptance doors share one dedupe index

The design constraint of the thread-service work is that the subagent-result
door reuses the inbound door's `(scope, source_binding_id, external_event_id)`
index rather than opening a second parallel one. Both `contract.rs` and
`filesystem_service.rs` assert this in prose; no test observed it. Every case
in this suite drove one door at a time, so a refactor giving the subagent door
its own index path would have left all of them green.

Equally untested was the fail-closed collision guard that keeps a user or
steering row from being handed back to a parent as its child's result.

One case per production backend closes both gaps: claim the tuple through
`accept_inbound_message`, then offer the same tuple to `accept_subagent_result`
and require a `Backend` error naming the non-system row, with the thread still
holding exactly the one user row.

Proven non-vacuous by weakening each half in turn, both backends:
  - delete the `kind != System` guard -> both new cases fail, returning the
    user row as `AcceptedSubagentResult { idempotent_replay: true }`;
  - namespace the subagent door's index key -> both new cases fail, minting a
    second row at sequence 2.
In both weakenings the other 13 cases in the file stayed green, which is the
coverage gap this commit closes.

* test(loop-contracts): pin all seven historical LoopInput wire tags

`historical_loop_input_forms_still_deserialize` pinned 4 of the 7 variants,
leaving `interrupt`, `cancel`, and `capability_surface_changed` unguarded.
`LoopInput` is serialized whole into the durable run-queue document, where one
unparseable entry corrupts an entire run's queue rather than one message, so a
half-pinned tag set is the gap the test exists to close.

Verified non-vacuous: renaming `Interrupt`'s field on the wire turns the test
red with `missing field 'interrupt_kind'`.

* fix(stress): map InvalidSubagentResult in the stress harness

dba5f41 fixed only the ironclaw_assistant match site because it was
verified with 'cargo check -p ironclaw_assistant' rather than at
workspace scope. tools/ironclaw_stress is a workspace member and its
thread_failure match is exhaustive with no wildcard, so the workspace
still failed to build with E0004.

Verified this time at the right scope: 'cargo check --workspace
--all-targets' now reports 0 errors.

* test(threads): pin mismatched-payload replay parity and the subagent race

Two gaps the subagent-result suite left open.

Mismatched-payload replay: both production backends key acceptance on the
identity tuple alone, so a retry carrying different content under a committed
identity is answered with the row that already exists — no second row, no
rewrite of the transcript, still MessageKind::System. Pinned on both backends
behind Arc<dyn SessionThreadService>. The filesystem `request_fingerprint`
decides only the claimed-but-unwritten recovery window, so that branch gets its
own case: a changed payload must not resume someone else's claim, and the
refusal must not poison the claim for the payload it belongs to.

Concurrency: two deliveries of the same child result now race for one claim on
the non-transactional backend, behind a two-party barrier on BeginTxn that
forces both onto the claim-then-write protocol after both have read "no
record". Asserts one durable System row, one shared message id and sequence,
exactly one `idempotent_replay`, and that the loser burns no sequence.

* test(agent-loop): drive the real drain call site for settled subagents

The predicate-only test could not see what production actually does with a
`SubagentSettled` input. Replace it with a `consume_drainable_inputs` test
that runs both user-facing drain modes over a batch where the settled input
sits directly ahead of a `GateResolved` barrier, asserting the cursor
advances by exactly one and only the settled input's ack token comes back —
consumption, not mere classification.

* test(turn-runner): pin the fail-closed guard on both merged delivery keys

`edge_from_record`'s fallback branch refuses a blob that parses as an
`AwaitedChildSetRecord` but carries junk under `appended_message_ref` or
`attention_outcome`. Nothing drove either error path, so a refactor to
`.ok()` would have stayed green. Extend the existing fail-closed test with
one case per key, asserting the refusal names the offending key.

* refactor(turn-runner): move the await-edge store tests into their own file

store.rs had grown to 1,046 lines with the `#[cfg(test)]` module starting at
472 — over half the file was tests, and the file crossed the repo's 1,000-line
ceiling for touched source. Split the test module into `store/tests.rs`,
matching the idiom already used three times in this crate
(`structured_finalization/tests.rs`, `loop_driver_host/compaction_tests.rs`,
`loop_driver_host/run_lease_fence_tests.rs`).

Pure move: the production half of `store.rs` is byte-identical to before, and
the test body differs only by the rustfmt reflow that follows dedenting it one
level. No behavior delta. `store.rs` is now 473 lines.

* docs(subagent-spawn): the delivered result row never enters the steering ladder

§4.1 told slice 2b to bind the appended subagent-result row to a queue entry
"exactly as steering rows do (`mark_message_queued` → `enqueue_queued_message`)".
It cannot: the acceptance writes the row `System`/`Finalized`
(filesystem_service.rs:2201) and `ensure_user_accepted` (:4378, in_memory.rs:1820)
admits only `User` rows in {Accepted, DeferredBusy, Queued}. Both
mark_message_queued (:2808) and mark_message_submitted (:2756) gate on it, so the
queue's best-effort flip_submitted (input_queue.rs:572) fails permanently and
retains the pending flip; retained flips count against MAX_QUEUED_INPUTS_PER_RUN
(:385, =32), so a long-lived parent would refuse all input — human steering
included — after 32 child settlements, and is_settled (:549) never holds, so the
durable per-run document is never reclaimed (durable_input_queue.rs:184, :370).
Even a succeeding mark_message_queued sets `Queued`, which is_model_visible
(:4397) excludes — hiding the delivered result from the parent's own context.

Corrects §4.1, the §4.3 `ironclaw_threads` row, and §9 Task 6 (step 2 + Files):
the row is appended `Finalized` and never marked `Queued`; 2b calls
`enqueue_queued_message` alone and makes the `Submitted` flip a no-op for an
already-terminal row in both thread backends. Adds dated decision-log entry D14,
which records the rejected alternative — widening `ensure_user_accepted` to admit
system rows would re-open `Queued`/`RejectedBusy` onto a result row and make
untrusted child text indistinguishable from a human instruction.

Pins today's refusal on both production backends
(a_result_row_is_refused_by_the_steering_ladder), asserting the
InvalidMessageTransition shape — message id, `from == Finalized`, and the
attempted operation — for both mark_message_queued and mark_message_submitted,
so 2b meets a red test instead of a wedged parent run. No production code change.

* fix(processes): make the dependency lifecycle a relation the kernel enforces

The state-column CAS refused terminal targets, replayed idempotently on
`state == next`, and checked `state == expected` — but never checked that
`(expected, next)` was a legal edge. `expected: Settled, next:
AttentionScheduled` was accepted, skipping `ResultAppended` entirely;
`apply_close_dependency` then consumed `AttentionScheduled` and released the
descendant reservation with nothing on record saying a result was ever
appended. The one test covering the ordering passed only because its caller
happened to pick the right `expected` — it pinned caller discipline, not a
guard.

`ProcessDependencyState::legal_predecessors` makes the relation a total
function on the enum: a new variant cannot compile without naming its
predecessors, and both closing doors — the CAS and consume/abandon — read the
same relation instead of each carrying its own `matches!`.

`TransitionProcessDependencyRequest::expected` is deleted. The CAS now
advances to `next` when the stored state is a legal predecessor of `next`.
Concurrency is unchanged: a double-drive of one step still hits the
`state == next` idempotent return, and a racer arriving late finds a state
that is not a legal predecessor and loses — exactly what `expected` bought,
derived rather than asserted. `StoredProcessCommand::TransitionDependency` is
a journaled, serialized command, so this is a durable-format change; it is
free today because this slice has zero producers (verified: the only non-test
callers of `transition_process_dependency` are `AwaitEdgeStore::transition`,
whose three callers `record_result_appended` / `record_attention` /
`defer_streak_capped` are reached only from tests). Once 2b ships producers
it stops being free.

Collapsed into the relation:
- `apply_close_dependency`'s bespoke `Settled | AttentionScheduled` check.
- Five duplicated closed-state predicates -> `ProcessDependencyState::is_closed`,
  including the derived `closed` **index** in `journal_store/rows.rs`, which was
  a non-exhaustive `matches!` that would have silently mis-indexed a future
  terminal variant. All three in-flight delivery states still index as not
  closed, pinned through both readers (the in-memory query filter and
  `unresolved_process_dependencies`, which reads that index directly).
- `record_attention`'s `peek`-then-CAS and its `_ =>` wildcard predecessor
  selector, which existed only to reconstruct an `expected` the kernel can now
  derive. The design record lists that wildcard as open 2b debt; it no longer
  exists, so that bullet is stale.

Also collapses `edge_from_record`'s two-shape decode to one total decode. The
shapes are provably disjoint (`AwaitedChildSetRecord` lacks `parent_thread_id`,
`state`, `reservation_release` and `created_at`, all required by `AwaitEdge`)
and the only writer of a serialized `AwaitEdge` into dependency metadata was
one test helper, now writing the production blob. Commit 80663be was that
fallback biting. The discarded-cause `Err(_)` goes with it.

Tests: `DEPENDENCY_DELIVERY_CHAIN` and its `position()` index arithmetic are
gone — a linear array cannot express a branch, and index 2->3 asserted
`AttentionScheduled -> AttentionDeferred` was legal, which it must not be.
Replaced by `DEPENDENCY_TRANSITION_EDGES`, a table over every ordered
non-terminal pair with its expected outcome, plus a same-state idempotent
replay test that pins metadata is not clobbered.

The kernel vocabulary stays domain-neutral: a settled dependency records its
result, its dependent is made attentive, then it closes.

* docs(subagent-spawn): retire the debt entry the kernel change deleted

record_attention's peek-then-CAS and its `_ =>` predecessor wildcard were
deleted in 39a823d, not deferred: the kernel now derives the expected
state from ProcessDependencyState::legal_predecessors. The open-items list
still carried them. Also records the unbounded-dependency-query charter gap
found during review, so 2b's sweeps meet it as a stated charter fix.

* fix(threads): frame child text in the type, not in the caller

`accept_subagent_result` persists its row as `MessageKind::System`, and a
system-kind row reaches the model's *system* role: `model_role_for_kind`
(`loop_host/src/lib.rs:3462`) -> `HostManagedModelMessageRole::System` ->
`ChatMessage::system` (`model_gateway.rs:2354`) -> the provider's top-level
`system` field (`anthropic_oauth.rs:1249`, `rig_adapter.rs:504`). The
request took a `MessageContent`, which any caller can build from arbitrary
raw text, so a producer that skipped the resolver's framing would promote an
injected child instruction into host authority. Nothing calls the door yet;
the point is that its safety must not depend on every future caller
remembering to wrap.

`AcceptSubagentResultRequest.content` is now `FramedSubagentText`, whose only
constructor frames — same shape as this crate's `ToolResultSafeSummary`.
`frame` prepends an explicit untrusted preamble, wraps the body in the `|||`
delimiters the turn runner already uses, and neutralizes control characters
and pipe runs so a child cannot close the frame from inside and continue as
host text. Nothing is truncated. Attachments leave this door: a delivered
child result is text (design record §2.7).

No new dependency edge — `ironclaw_threads` still imports neither
`ironclaw_turn_runner` nor `ironclaw_processes`.

Red before green: with `frame` reduced to identity, the new case fails on
both backends with "raw child text reached the durable row verbatim".

* test(agent-loop): drive a settled subagent result through the real drain caller

`consume_drainable_inputs` is a pure function: it classifies inputs and
advances the cursor, and that is all a test at that level can see. The
sequence a settled subagent result actually depends on lives one layer up in
`InputStage::process` — write the `BeforeModel` checkpoint of the advanced
cursor, and only then ack, because the ack is what flips the queued
transcript row to `Submitted` and makes it model-visible.

Drive `[SubagentSettled, GateResolved]` through `InputStage::process` in both
user-facing drain modes and pin both halves: the settled input advances the
cursor, checkpoints it, and is the only token acked; the gate is a barrier
that stops the drain with its own ack token untouched.

* docs(subagent-spawn): cite the symbol, not the line that already moved

Both doc comments in the acceptance suite and twenty citations added to the
design record pinned cross-crate call sites by absolute line number. Nothing
fails when those drift, and three of the six numbers in the steering-ladder
comment already resolve to unrelated code — two of them to a bare `}` —
inside the branch that wrote them.

Cite the symbols instead: `ensure_user_accepted`, `is_model_visible`,
`MAX_QUEUED_INPUTS_PER_RUN`, `is_settled`, `flip_submitted`. They were
already in the prose, so nothing is lost and the citations survive a
refactor. Five design-record citations named no symbol and were given one,
each resolved against the tree first. The two pre-existing line citations are
left alone.

* fix(threads): drop the dead serde attribute, keep the one-way frame

Two review findings on `FramedSubagentText`.

`#[serde(transparent)]` removed. The filed security concern does not
apply — the type derives `Serialize` only, so there is no wire
construction path to bypass `frame()`, and `.claude/rules/types.md`
aims that flag at `transparent` + derived `Deserialize`. But the
attribute is dead weight: the type's one serializer is
`subagent_acceptance_fingerprint`, and serde_json emits a plain newtype
struct as its inner value, so the persisted fingerprint bytes are
unchanged (verified with a throwaway equality test). It also leaves a
trap for whoever later adds `Deserialize`. Gone, and named in the doc
comment alongside the other deliberate absences.

Neutralization stays one-way. The second finding read the framed value
as the only copy of the child's output; it is a derived copy in the
*parent's* thread. The child's verbatim text is a finalized assistant
row in the child's own thread — `child_terminal_output` reads it back
to build this one — and nothing on the settle path deletes or redacts
it (`delete_thread` has no production callers). "LLM data is never
deleted" governs the row, not every projection of it; the sibling
`sanitize_untrusted_terminal_reason` already truncates the same text to
512 bytes. A reversible escape would buy retention already guaranteed
at the source while handing an injected child escape syntax to reason
about from inside the delimiters. The doc comment now says so.

* test(agent-loop): assert the persisted checkpoint cursor, not just kind and final state

checkpoint_kinds() only proves a BeforeModel checkpoint happened; the final
in-memory cursor only proves the executor's own state advanced. Neither
proves what cursor value the checkpoint payload actually carried, so a
regression that persists a stale cursor and only later advances the
in-memory one would still pass. Decode the staged BeforeModel payload
(MockHost already captures it via staged_payloads()) and assert its cursor
directly, in both drain modes.

Task 1 of the background-subagents slice: the spawn-args wire codec now

* refactor(loop-host): bind_input_enqueue on the settler seam

Add AwaitEdgeSettler::bind_input_enqueue (mirroring bind_result_writer's
deferred-binding pattern) so the background-mode delivery tail landing in
Task 5 can later enqueue a settled child's result as steering input for a
live parent run. Wires the resolver's OnceLock field, the inherent and
trait-impl bind methods, and the composition-side bind call right after
host_input_queue is built. No AwaitEdgeSettler double exists outside the
resolver (rg -n "impl AwaitEdgeSettler" crates/ tests/), so there is no
second implementor to update. Structural only: no behavior change — the
bound port has no caller yet.

* feat(turn-runner): background results append and enqueue per child

Adds AwaitEdgeResolver::deliver_background, the settle_and_maybe_drain
branch that routes SpawnSubagentMode::Background edges to it instead of
drain_settled_group (blocking mode is unchanged), and the resolver's
production HostInputEnqueuePort/LoopInput imports.

deliver_background walks the delivery chain end to end:

1. Append (idempotent): frame the child's final text (or failure summary)
   with FramedSubagentText::frame, accept it onto the parent thread via
   SessionThreadService::accept_subagent_result, and record the resulting
   message ref with AwaitEdgeStore::record_result_appended. A re-peeked
   edge that already carries appended_message_ref reuses it instead of
   accepting a second row (accept_subagent_result's own idempotency covers
   a mid-step crash).
2. Attend: query AgentTurnSpawnTreeRuntimePort::recent_runs_for_thread for
   the parent's newest run; a live, non-terminal record gets the settled
   result enqueued as LoopInput::SubagentSettled through the bound
   HostInputEnqueuePort, then AwaitEdgeStore::record_attention. No live
   run, an unbound port, or the enqueue itself refusing with
   RunClosed/CapacityExhausted/Disabled all leave the edge parked in
   ResultAppended and return Ok(Drained) rather than erroring — Task 6
   (2c) adds the parked-parent activation path.
3. Close only from AttentionScheduled, via AwaitEdgeStore::close.

Turn-runner runtime wiring (crates/loop/ironclaw_turn_runner/src/runtime.rs)
is deliberately NOT touched: parts.input_queue there is Option<Arc<dyn
HostInputQueue>> (the drain-reader half only), which does not implement
HostInputEnqueuePort, so there is no enqueue-capable handle to bind. The
resolver treats that unbound state as "no live queue" (the same
ResultAppended fall-through), not an error — composition's
bind_input_enqueue call (previous commit) covers the production path.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(turn-runner): parked parents are activated with system provenance

Task 6 (2c): replaces deliver_background's "parked-parent activation
lands here" fall-through with a real activate_parked_parent branch.
When a background child settles and its parent has no live run (or
the live-run enqueue itself refuses), the resolver now wakes the
parent through TurnCoordinator::activate with
ActivationProvenance::System, preserving the parent's own run profile
id. A streak-cap refusal parks the edge at AttentionDeferredStreakCap
(unclosed, excluded from autonomous retry); any other activation
refusal (ThreadBusy, transient Unavailable, ...) leaves the edge at
ResultAppended for the next drive to re-attend. Re-drive entry now
special-cases AttentionScheduled (close only) and
AttentionDeferredStreakCap (no-op) so a crash between activation and
close never triggers a second activate() call.

* refactor(processes): keyset paging on the dependency query

ProcessDependencyQuery gains after/limit fields (keyset cursor over the
existing canonical (dependent_process_id, dependency_process_id) sort
key). Both None reproduces the pre-existing unbounded query
byte-for-byte; a bounded request walks a new process_dependency_canonical_v1
index directly, applying filters before the cursor/limit bound, so a
bounded read stops once it collects `limit` matching rows instead of
draining the whole scope.

Adds the plumbing the run-start sweep needs without wiring it up yet:
AwaitEdgeSettler::sweep_thread_on_run_start (trait method + a real
resolver implementation, unreached by any production caller),
AwaitEdgeStore::list_background_for_thread, and a required
await_edge_settler field on RebornTurnRunExecutor (constructed
everywhere, not yet invoked from execute_claimed_run). No behavior
change for any existing caller.

* feat(turn-runner): run-start and boot sweeps heal background delivery

RebornTurnRunExecutor now calls AwaitEdgeSettler::sweep_thread_on_run_start
before invoke_driver on every claimed run, deriving human_initiated
from the claimed run's subagent_activation_provenance (absent/Human is
permitted; System/ParentAgent is not). The resolver's sweep walks the
thread's background dependency edges (bounded at
MAX_QUEUED_INPUTS_PER_RUN) and drives each through deliver_background's
existing idempotent re-drive: Settled/ResultAppended/AttentionScheduled
redeliver or close; AttentionDeferredStreakCap drains forward only when
human_initiated permits it (deliver_background gains a retry_deferred
parameter for this one caller — the reactive settle path keeps its
autonomous no-retry default). A sweep failure is logged and never fails
the run start.

boot_recovery's recover_scope replaces its ponytail no-op arms for the
background delivery substates: Settled(background)/ResultAppended
deliver through deliver_background (parked-parent activation included,
System provenance); AttentionScheduled closes only; a streak-capped
edge stays parked for a later permitted/human start. Blocking-mode
Settled keeps its pre-existing drain_settled_group path unchanged.

  per-child arrival, "do not poll". No Rust change needed — the

  and await_edge_port.rs doc comments off the deleted
  thread-harness-design.md onto docs/internal/reborn/subagent-spawn/
  README.md's own sections (boot_recovery.rs carries none). store.rs's

  and are left as-is.

  (resolver.rs:1709, :1785)" — both were test-module lines; the only
  production recovery caller is subagent_spawn_port.rs's finish_spawn,
  confirmed by `rg -n check_scope_recovered`.

* fix(threads): scope the D14 finalized no-op to subagent-result rows

The D14 guard in `mark_message_submitted` checked `status == Finalized`
alone, so every finalized row — `Assistant`, `ToolResultReference`,
`CapabilityDisplayPreview` — returned Ok where it previously returned
`InvalidMessageTransition`. A caller aiming at the wrong message id was
masked instead of failing loud.

Subagent-result rows are written `MessageKind::System` by
`accept_subagent_result` in both backends, so the guard now requires that
kind; every other finalized kind falls through to `ensure_user_accepted`
and errors as before.

Extends `a_result_row_is_refused_by_the_steering_ladder` with the negative
half; it fails on both backends without the narrowing.

* fix(processes): fail loud on truncated pages, filter dependent_id in memory

Two defects in the bounded dependency query added by this branch.

`dependent_id` is the canonical index's sort key, not part of its equality
prefix. `ordered_query_prefix_values` requires the filter's equality-key
set to equal exactly the keys preceding the sort key (here
`lineage_scope_key` alone), so passing `dependent_process_id` as an
index-level equality filter made the ordered query Unsupported instead of
narrowing it. Latent today — no caller pairs `dependent_process_id:
Some(..)` with a `limit` — but armed for the next one. It now filters in
memory per page, like `group_ref`/`include_closed`.

A full page whose last row yields no cursor now returns Deserialization
rather than breaking out with a silent short read, matching the unbounded
sibling `query_indexed_collection`.

Adds libSQL parity coverage and the previously untested `limit == 0`,
`dependent_process_id: Some(..)`, and `include_closed: true` branches; the
dependent-filter bug surfaced from that coverage.

* docs(subagent-spawn): correct §2.1 and finish the §9 closeout

§2.1 "What ships today" still described the pre-slice-2b behavior — codec

`mode`, `finish_spawn` hard-codes Blocking — all three now false. §9's
closeout sentence was truncated and claimed three slices while naming two.

Rewritten against live code, keeping the caveat that
`builtin.spawn_subagent` remains in `disabled_capability_ids` and is not
model-reachable until R9.

* fix(ci): repoint coverage exemptions after the resolver test move

f0c0b65 moved the await-edge resolver tests into their own file,
shrinking resolver.rs 2141 -> 1535 lines, but left two line-referenced
exemptions pointing at the old offsets. #38 (2032) fell past EOF and
failed the changed-coverage manifest validator; #55 (563) still resolved
and so silently exempted unrelated code.

Both statements verified present in each revision: the background gate-ref
arm moved 2032 -> 1427, and handle_child_terminal_inner's return type
563 -> 853. Scope, owner, and rationale are unchanged.

… consumer (nearai#7770 phase 1) (nearai#7765)

* feat(memory): periodic memory-curation pass ("dreaming"), first slice (nearai#7276)

Memory only ever grew. Writes accumulate, nothing prunes, and the standing
document has a byte budget, so redundancy crowds out what matters. No human
reads the file, so the decay is invisible.

This adds the Hermes-shaped answer: every N completed user turns, the agent
runs with no user present, re-reads its standing memory, and tidies it —
merging duplicates, resolving superseded facts, tightening wording. Its
output is the edits plus a structured report; nothing is sent to anyone.

Buildable now because unbound turns landed (nearai#7562/nearai#7634): a run with no
conversation and no reply target. The pass is submitted through the same
`UnboundTurnService` door OpenAI-compat and subagent spawn already use.

Shape. The loop tier owns only the observation ("an ordinary user turn
completed, under this scope") and reports it through a port; every policy
decision lives in the product tier. The port vocabulary sits in
`ironclaw_loop_contracts` rather than the runner because WS1.7 deliberately
removed `ironclaw_turn_runner` as a production dependency of
`ironclaw_assistant`, and this must not reverse that.

The load-bearing guard: an unbound run NEVER triggers curation. A pass is
itself unbound, so triggering on unbound completion would let each pass
schedule its successor — an unbounded background loop running the model
against a user's memory forever. Pinned by test, both unbound profiles.

Also fixed along the way: `UnboundTurnSubmission` had no way to declare
limits, so it always inherited the profile's 1024-iteration budget and no
wall clock. Fine for a user waiting on a panel, wrong for an unwatched
background chore — an unconverged pass would burn tokens against a user's
memory until that ceiling, and nobody would notice. Added narrowing-only
limits (existing callers unchanged, explicitly defaulted) and the pass
declares 6 model calls / 12 capability calls / 90s.

Safety properties pinned by tests: the pass acts as the owner and never as
an operator-config caller; it gets the three memory capabilities and nothing
else; its id doubles as the idempotency key so a crash-retry converges on
the same pass; a failed submission is swallowed at debug (post-terminal
background path — info!/warn! would corrupt the REPL).

Concurrency is safe without batch-atomic memory ops: memory writes are
compare-and-swap, so a pass racing a live conversation loses the write
rather than clobbering it. The failure mode is a lost curation pass, never
a lost memory.

Not wired into composition yet — no deployment runs this. Wiring, the
gate-behavior decision (unbound runs abort on approval gates, so users with
auto-approve off need skip-not-abort), and an integration scenario follow.

* fix(memory): avoid an extension name in curation comments

The extension-specificity gate scans generic code for concrete extension
names; "with slack for one retry" tripped it on the English word. Reworded
rather than allowlisted — the allowlist is for pre-existing debt, not for
new code that can simply say something else.

* refactor(memory): move the curation contract into ironclaw_memory

Memory vocabulary belongs with the memory contract. "Curation" means
nothing outside memory, and the signal exists only to decide whether a
user's memory needs tidying — putting it in ironclaw_loop_contracts made
the loop-contracts crate carry a memory concept it has no stake in.

Both tiers already depend on ironclaw_memory (the runner for after-turn
recording, the product tier for the memory service), so this pulls in no
new edge; it only puts the type where its domain lives.

* feat(hooks): add privileged AfterTurn lifecycle point

Adds `HookPointSpec::AfterTurn`, a privileged-only hook point that fires
once after a turn's run reaches a terminal state — the seam for work about
the turn as a whole rather than about one model call, capability
invocation, or checkpoint.

- `AfterTurnHookContext` (`points/turn.rs`) carries tenant/user/agent/
  project plus a `completed` flag. `user_id` is non-optional and there is
  deliberately no `unbound` field: the dispatch call site never fires this
  point for unbound runs, because hook-started background work runs
  unbound and firing on unbound completion would let each background pass
  schedule its own successor forever. Observing background runs stays with
  `EventTriggered` + `LoopCompleted`, which is observer-only.
- `PrivilegedAfterTurnHook` takes no sink: an AfterTurn hook may hold its
  own collaborators and start follow-on work as a side effect. The
  sealed-return-type law stays scoped to points untrusted tiers can reach.
- `install_after_turn` rejects `Installed` and `SelfAuthored` at install
  time; `install_observer` rejects the point outright.
- `dispatch_after_turn` mirrors the observer dispatch shape (ordered
  snapshot, poison handling, failure policy, telemetry) with a 5s per-hook
  timeout, and never propagates a hook failure to the caller.
- New `DecisionKind::Lifecycle` (three in-crate consumers, all updated):
  act-capable but fails isolated, since the run it observes is already
  terminal.

* refactor(memory): curation rides the AfterTurn hook point, bespoke port deleted

nearai#7765 landed memory curation on a bespoke `AfterTurnCurationPort` because no
general lifecycle seam existed yet. The `AfterTurn` hook point now exists, so
the port is deleted and curation becomes one privileged hook among others.

- `ironclaw_memory` sheds `src/curation.rs` entirely: memory carries no
  hook-framework vocabulary and no bespoke port.
- `ironclaw_turn_runner` gains `after_turn_hooks::after_turn_hook_context`,
  which keeps the two guards centrally so no hook has to remember them: an
  unbound run never fires the point (hook-started background work runs
  unbound, so firing on unbound completion would let each pass schedule its
  own successor forever), and an actorless run never fires it (nothing to
  attribute follow-on work to).
- The executor's `after_turn_curation` field becomes
  `after_turn_hooks: Option<Arc<HookDispatcher>>` with `with_after_turn_hooks`.
  The 5s bound survives as an OUTER backstop around the whole dispatch; the
  dispatcher already bounds each hook.
- Semantic widening: the point fires for ANY terminal state of an ordinary
  actor-bearing run, not just `Completed`. Hooks that only want successes read
  `ctx.completed` — which `MemoryCurationService` does, first thing, because a
  failed turn says nothing about whether memory needs tidying and counting it
  would drift the interval.
- `MemoryCurationService` implements `PrivilegedAfterTurnHook`; every policy
  decision (interval, per-owner counters, pass building, idempotency key)
  is unchanged. `ironclaw_assistant` takes a normal `ironclaw_hooks`
  dependency — products→loops, the edge it already has via `ironclaw_loop_host`.
- `AfterTurnHookContext::new` added: the struct is `#[non_exhaustive]` and the
  call site is outside `ironclaw_hooks`, so a struct literal is unavailable.

The dispatcher is un-wired (`None`) after this commit; composition follows.

* feat(memory): wire curation through composition behind [memory] config

Phase 1 of nearai#7770 ends where it should: the `AfterTurn` point has a live
consumer. Composition registers the memory-curation hook, so after every Nth
completed turn the agent goes off on its own and tidies the user's standing
memory document (nearai#7276).

- `[memory].curation_interval_turns` (`ironclaw_config`): opt-in, serde-default
  absent. Absent means the hook is NEVER REGISTERED — disabled is expressed by
  not wiring, never by a sentinel, so a written `0` is rejected at parse time
  rather than clamped downstream into "after every turn". Config-only, no env
  override: that matches `provider`/`admin_overrides`, and only the mem0
  connection fields carry an env convention.
- `ironclaw_assistant::memory_curation::after_turn_curation_dispatcher` owns the
  assembly — which hook, at which phase (`Telemetry`: the run is already
  terminal, so it enforces nothing), under which trust class (`Builtin`), behind
  the stable `HookId::for_builtin` path. Composition calls it; per AGENTS.md the
  wiring root does not own module policy. Its own small dispatcher, not the
  per-run middleware one: `after_turn` fires once per run from a
  process-lifetime `Arc`.
- `DefaultPlannedRuntimeParts::after_turn_hook_dispatcher_factory` is a factory,
  not a ready dispatcher, because the `UnboundTurnService` the hook submits
  through is built from the coordinator the same function builds. Handed
  `AfterTurnHookDeps` once, after those exist; may still decline.
- Two conditions gate registration in composition: an operator asked for an
  interval AND a memory provider resolved. A pass over a document no provider
  backs would submit a run whose only three tools do not exist.

Gate posture (nearai#7770's skip-and-note) is deliberately NOT implemented; a
`DECISION nearai#7770:` comment at the submission site records why. No read-only
"would this capability gate for this scope" query exists: the answer needs the
descriptor's effects and origin-gate matrix, the run's `ApprovalPolicy`, the
`TrustDecision`, grants, and leases composed inside
`authorize_dispatch_with_trust` at dispatch time, with an origin that does not
exist until the run is executing. Approximating it from
`ApprovalSettingsProvider::global_auto_approve` alone would duplicate gate
composition in a product service. The seam that is actually missing is at the
gate strategy: a `GateOutcome` that skips the capability for the model instead
of aborting the unbound run.

Tests: two group scenarios drive the wired path end to end — the pass's thread
id is its idempotency key and therefore deterministic, which is what lets the
harness script the background pass's model at all. The positive scenario runs N
ordinary turns and asserts the tidied text reaches a LATER conversation's prompt
under the same user's own memory lane; the negative asserts an empty pass script
below the interval and then corroborates it by crossing the interval one turn
later, so "empty" cannot be latency. Both falsified by moving the interval.
`with_memory_curation_interval()` on the group builder mirrors production's
opt-in exactly; the wiring-parity tripwire and composition mass gate move with
the new field.

* fix(memory): review round — per-trigger pass identity, conversation-only triggers, fail-closed install

Six review findings on nearai#7765 (epic nearai#7770 phase 1).

- **Pass identity was the number of OWNERS, not passes.** The curation pass id
  was `…-{counters.len()}`, which for one user is forever `1`: every interval
  after the first reused the same public id and idempotency key, so the unbound
  accept door REPLAYED the first pass instead of running a new one — the
  document would be curated exactly once, ever, with nothing surfacing it.
  `AfterTurnHookContext` now carries `run_id` (the terminal run that fired the
  point), the runner threads it through, and the pass id is
  `memory-curation-{tenant}-{user}-{run_id}`: distinct per trigger, and
  replayed as-is by a crash-retry of the same trigger, with no durable counter.
- **Scheduled-trigger fires and subagent children no longer count.** A trusted
  fire keeps its creator as `TurnActor` and runs a non-unbound profile, so it
  passed both original guards and could launch a write-capable pass with no
  user present. The derivation is now an ALLOWLIST of conversation profiles
  (`reborn-planned-default`, `interactive_default`, `default`); the
  denylist shape failed open for every profile added later.
- **Curation install fails closed.** `AfterTurnHookDispatcherFactory` returns
  `Result` and the runtime build propagates it as
  `DefaultPlannedRuntimeBuildError::AfterTurnHooks`. Declining is expressed by
  supplying no factory, never by a swallowed error that leaves a deployment
  believing memory is being tidied.
- **A zero interval is unrepresentable downstream.** Config already rejected
  `curation_interval_turns = 0`; `NonZeroU32` now carries through the input
  builder into `MemoryCurationService`, and the clamp is gone.
- **Typed error and typed counter key.** `CurationPassSubmitter::submit_pass`
  returns `UnboundTurnError`; counters key on a `(TenantId, UserId)` struct.
- `// arch-exempt:` on the executor's hook field uses the enforced
  `plan #NNNN` form.

Tests: distinct-vs-converging pass ids; scheduled-trigger and subagent profiles
yield no context, planned-default does; the executor actually dispatches at the
seam (recording hook over a completed bound run, and never for an unbound one);
`accept_and_submit` journals the declared `TurnLimits`. The two curation
scenarios script the pass by owner-scoped thread PREFIX — a new test-support
`register_scope_script_prefix_for_test` — because a per-run pass id is not
knowable before the triggering turn runs.

* fix(ci): panic-free interval const + QA harness field the sweep missed

Two breaks, one class: struct call sites in test bins the local
verification set never compiled.

- The production panic baseline scans syntactically, so the compile-time
  `match … unreachable!()` NonZeroU32 constructor counted as a new panic.
  Replaced with `NonZeroU32::MIN.saturating_add(9)` — const, panic-free,
  and the comment says why the odd spelling exists.
- `reborn_parity_qa/binary_e2e.rs` initializes DefaultPlannedRuntimeParts
  and needed the new `after_turn_hook_dispatcher_factory` field (None: QA
  replay drives no lifecycle hooks).

Verified with `cargo check --workspace --tests` — the command that
covers every bin, which the per-crate verification lists did not.

* fix(filesystem): satisfy the Rust 1.98 chunks_exact_to_as_chunks lint

Rust stable 1.98 rolled through CI today and its new clippy lint fails
every branch on decode_embedding_blob's chunks_exact. as_chunks is the
better code anyway: const chunk size yields [u8; 4] directly, so the
per-element indexing disappears. Behavior pinned by the existing vector
tests.

Not this branch's code — the same fix goes to main in its own PR so
every other open branch stops failing too.

* fix(lints): complete the Rust 1.98 clippy migration

Full-workspace sweep under 1.98 (the toolchain CI now runs), on top of the
vector.rs fix already on this branch:

- result_large_err: GoogleCredentialError boxes its Recovery projection
  (one variant, nine sites' worth of warnings); agent_loop's batch error
  boxes its host error; turn_runner boxes only HostFinalizationFailed's
  payload — DriverError stays unboxed because five match sites destructure
  it by pattern, and it is not the oversized member.
- chunks_exact_to_as_chunks: the two UTF-16 decoders in coding/text.rs.
- useless_format in a trace_commons test.

All private types or contained call sites; no public API changes beyond
the boxed variant payloads inside their own crates.

* fix(lints): last two 1.98 sites — map_or_identity, test-support large errors

The tracing-syntax architecture test's map_or(len, |end| end) becomes
unwrap_or; db_write_measurement's error enum boxes its DbProbeError
payloads (test-support only, ~5 construction sites).

Full-workspace clippy --tests under 1.98: clean.

* docs(hooks): Lifecycle-vs-Effect rationale + amend the side-effect invariant

Approach-audit disposition on nearai#7770 (accepted findings ST3/SP3):

- trust.rs documents why Lifecycle is not a duplicate of Effect: Effect is
  permitted for Installed/SelfAuthored by default — the third-party class
  for post-durable-fact event hooks — while turn completion must not carry
  that default. Folding them would silently widen who may react to a
  finished turn.
- The hooks contract's side-effect invariant now names mediated
  prepared-context turn submission as a sanctioned route for Lifecycle
  hooks, instead of the code silently diverging from a list written before
  unbound turns existed.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(memory): audit round 2 — fail-closed curation gate, per-run hook dispatcher

Second approach audit on nearai#7765 (nearai#7770 phase 1). Six accepted findings plus
the documentation gaps they exposed.

Fail closed on a provider that cannot curate. Composition registered curation
whenever an interval was configured and any memory provider resolved, but a
pass REPLACES the standing document and a bound third-party provider may
reject that write outright — a deployment would spawn passes forever that all
fail, with nothing surfacing it. `curation_interval_for_binding` now gates on
the resolved binding and turns a configured-but-unservable curation into a
startup error naming the provider and how to disable it. Nothing in a manifest
declares "supports standing-document replacement" (`[memory].lifecycle` is
about read/record hooks), so the gate is the native binding, with the missing
declaration named in the comment as the seam for nearai#7664.

Hook poison is run-scoped by contract, so the executor now holds a per-run
dispatcher FACTORY instead of one process-lifetime dispatcher: a panic or
timeout is barred for the run it happened in and retried on the next, instead
of disabling curation until restart. The curation SERVICE stays one long-lived
instance — its per-owner counters must accumulate across runs — and each fresh
dispatcher installs a binding over that same service.

Blocked states no longer dispatch. `after_turn_hook_context` requires
`TurnStatus::is_terminal()`: a gated-then-resumed turn fired the point twice,
once while still running.

Also: tier-specific `install_builtin_after_turn` / `install_trusted_after_turn`
replace the trust-class-parameterized installer (an invalid tier is now
unrepresentable, not rejected at runtime); the executor's outer dispatch bound
moves 5s -> 30s so it can never preempt the dispatcher's own per-hook timeout
classification; the unused default-interval constant is deleted and its "ten
matches Hermes" rationale moved to the config field a deployer reads; the
hooks consumer inventory gains `ironclaw_assistant`; and `points/turn.rs` now
states plainly that the point fires only for exits the executor applies —
scheduler failure terminalization does not dispatch it, tracked as a follow-up
on nearai#7770.

Composition budget 42198 -> 42316 (both records, dated): +7 wiring, +109 for
the fail-closed gate and its tests.

* fix(hooks): enforce the after_turn tier gate in the registry, and close the review gaps

CodeRabbit round three on nearai#7765.

`HookRegistry::insert` now refuses `Installed` / `SelfAuthored` bindings at
`HookPointSpec::AfterTurn`, alongside the phase-vs-trust gate it already
carries. The tier-split installers encoded the restriction, but raw bindings
reach the registry through `from_bindings` and the public builder's
`insert_binding`, which bypass them — the point is act-capable, so an
untrusted binding there would surface as a malformed binding mid-dispatch
instead of an install-time refusal.

The dispatcher's per-hook `after_turn` budget becomes injectable
(`HookDispatcherBuilder::with_after_turn_timeout`, defaulting to
`AFTER_TURN_HOOK_TIMEOUT`), which is what makes the timeout-race regression
affordable: the executor-seam test wedges one hook against a millisecond
budget and proves the hook ordered after it still runs, that the wedged one is
recorded as a Timeout failure, and that the already-terminal run is unaffected.
That asymmetry — outer backstop strictly larger than per-hook budget times hook
count — was fixed earlier but never pinned.

Executor-seam coverage also gains the two non-success terminal states: a FAILED
and a CANCELLED conversation run each dispatch exactly once with
`ctx.completed == false`.

The below-threshold curation scenario no longer rests on a single empty
reading, which a queued-but-unstarted pass would also produce. After crossing
the interval it now requires EXACTLY ONE pass — one pass's worth of model calls
and no more — which is what makes the earlier zero real rather than latency.

The group harness mirrors production's two-part activation gate: curation wires
only when an interval AND a bound memory provider are present, not from the
interval alone.

Version claims in two comments are reworded to name the lint rather than a
toolchain release nobody can verify offline.

* chore(composition): re-measure the mass budget after the main merge

The merge combined main's composition growth (notification inbox nearai#7697,
subagent slice nearai#7788) with this branch's curation wiring; the two
ceilings merged textually without a git conflict while the sum exceeded
both — the gate caught exactly the case it exists for. Ceiling and the
mirrored COMPOSITION_ABSOLUTE_SRC_LOC move together to the measured
42479, dated rationale in the toml. No composition code changes here.

* fix(memory): give the curation pass report headroom — live-test finding

The 2026-08-21 live test (DeepSeek-V4-Flash, isolated home, interval 2)
proved the machinery end to end — the pass fired exactly once, acted as
the user, consolidated two wordings of one fact into a correct merged
line, and read its own write back to verify — and then terminated
`Failed { model_call_limit }` before emitting its structured report. A
real model spends calls a scripted one does not: three writes where the
prompt asks for one, plus a fumbled read.

Two changes, both evidence-backed:
- MEMORY_CURATION_MAX_ITERATIONS 6 -> 10. The ceiling still hard-stops
  an unconverged pass; it now leaves room for the report after ordinary
  real-model imperfection.
- The prompt's Finishing section states the budget and the exact
  sequence (read -> at most one write -> result tool), and says plainly
  that a pass dying unreported is worse than a pass changing nothing.

The scripted integration scenario hands the model exactly three replies
and structurally cannot see this failure mode; the constants comment
records the live evidence so the next tuner knows where 10 came from.

* feat(extension-contracts): declare [[memory.scheduled_ops]] — pass ops, trust-gated, cost-floored

A memory provider can now declare its own recurring upkeep in its manifest
instead of the host hardcoding which provider gets which background work.
The provider names the work and the cadence; the host keeps the clock, the
invocation envelope, and the authority.

    [[memory.scheduled_ops]]
    trigger = "after_turn"
    interval_turns = 10
    pass = { prompt = "prompts/memory_curation.md", tools = ["ironclaw.memory.read", "ironclaw.memory.write"], max_model_calls = 10 }

Contracts tier only — nothing dispatches or invokes these yet.

`MemoryScheduledTrigger` is a closed host-owned vocabulary with exactly one
v0 entry; an unrecognized token fails the parse rather than being dropped,
because a silently ignored trigger presents as a provider whose declared
upkeep simply never runs. `MemoryScheduledOpKind` is tagged by which key the
entry declares, and `tool = "..."` is RECOGNIZED and REJECTED with its own
message rather than falling through to an unknown-field error, so a manifest
written against the eventual schema fails with intent. Both keys or neither
are errors too. The wire shape and the parsed shape are separate types, so
`MemoryScheduledOp` cannot be built from a manifest without clearing every
per-op rule.

Three bounds, each with its reason in a doc comment and a test:

- `interval_turns >= 2` (`MIN_SCHEDULED_OP_INTERVAL_TURNS`) — a manifest
  declares work that runs on someone else's deployment at their expense, so
  it must not be able to demand per-turn invocation. `NonZeroU32` makes
  "every 0 turns" unrepresentable before the floor even applies.
- `pass.max_model_calls <= 16` (`MAX_SCHEDULED_PASS_MODEL_CALLS`) — a pass is
  unwatched background spend with nobody reading the transcript. The nearai#7770
  live test put the realistic curation need at 10.
- At most one op per trigger — the host holds one interval counter per
  trigger per owner, so a second op has no well-defined cadence.

Two rules need the whole manifest and land in
`ironclaw_extension_registry::v3::validate_memory_scheduled_ops`, beside the
existing `[admin_configuration]` cross-check and for the same reason — only
that layer sees `[[tools]]` and the requested trust class next to `[memory]`:

- A pass's `tools` must be ids the SAME manifest declares. Declaration is
  selection, never authority: a memory provider must not schedule passes
  wielding another extension's tools.
- Only a first-party/system manifest may declare a pass op at all. A pass is
  a manifest-authored prompt running with write tools, as every user, on a
  schedule — a strictly larger grant than a model-chosen tool call, so it
  gets the same default-deny wall as the after-turn hook tiers. Host-bundled
  alone is not enough, pinned by a test that refuses a third-party-trust
  manifest from a host-bundled source.

`scheduled_ops` is serde-defaulted and empty when absent, so every manifest
written before it existed parses unchanged and schedules nothing
(`memory_manifest_without_scheduled_ops_still_parses`,
`scheduled_ops_absent_in_an_older_manifest_means_none`). `pass.prompt` reuses
`guidance_doc`'s validated bundled-asset ref type; asset RESOLUTION stays
host-side and fail-closed.

The §11.2.3 contracts size ceiling moves 10_841 -> 11_451 for the declaration
family and its inline tests, count read from the ratchet's own failure
message.

* feat(memory): scheduled ops drive curation — native declares its pass, opt-in stays

The declaration replaces the hardwired layer (nearai#7664 addendum v2):

- memory-native's manifest declares its curation as `[[memory.scheduled_ops]]`
  (after_turn, recommended cadence 10, pass over its own three memory tools,
  max_model_calls 10 — the live-test calibration). The curation prompt moves
  into the package beside the guidance doc, exported through the same asset
  table, resolved host-side fail-closed.
- `MemoryCurationService` dies; `MemoryScheduledOpRunner` is built FROM the
  resolved declaration (prompt text, tool ids, model-call ceiling), keeping
  the policy that was already pinned: per-owner counters, completed-only
  counting, the `memory-curation-` pass-id prefix as contract, the submitter
  seam, debug-only failure swallowing. The tool-op arm is
  unreachable-by-construction (leg A parse-rejects it) and says so explicitly.
- Composition's native-only gate arm dies: the gate is now "did the bound
  provider declare an op" — a configured interval against a provider that
  declares nothing stays a startup error naming the provider.

OPT-IN preserved (owner decision, 2026-08-22): the declaration ARMS upkeep —
validated shape, resolved prompt, recommended cadence — and
`[memory].curation_interval_turns` ENABLES it. Omitted = nothing runs,
exactly as before this change; a manifest cannot switch on background token
spend for a deployment that never asked. The config floor (>= 2) is now
enforced at parse, where the operator can read why.

Leg B built by a subagent (session-limited mid-flight), completed and
re-verified from the worktree; opt-in flip + config validation + marker

* fix(memory): the curation prompt demands an explicit append:false — live-test v2 finding

The declared-op live re-test (2026-08-23, DeepSeek-V4-Flash, fresh isolated
home): the pass reached its structured report — the model_call_limit death
from the first live test is fixed — but the model's FIRST write omitted
append:false, transiently duplicating the document before it self-corrected
with a proper replace two calls later. The prompt asked for one write; it
never said which KIND. Now it does, with the consequence spelled out.
