Subject: [PATCH 01/53] feat(opencode): add subagent interrupt
(steer/cancel/abort)
Experimental capability for a parent agent or human operator to steer,
gracefully cancel, or hard-abort a specific running Task subagent mid-run,
without affecting the parent or sibling subagents.
Core:
- Interrupt service (session/interrupt.ts): process-local registry holding
one pending interrupt per child plus a terminal record; steer/cancel frame
renderers and a visible-marker renderer, both with origin attribution
(user vs parent); reason length-capped and XML-escaped at every sink
(frames AND the visible marker).
- The child consumes pending interrupts at the runLoop turn boundary: steer
injects a frame and a visible "Steered by ..." marker and continues;
cancel injects + a visible marker, records a terminal, and
force-breaks within a grace window. abortChild writes a visible "Aborted
by ..." marker (model/agent derived from the child's latest user message),
records a terminal, and cancels the BackgroundJob.
Agent tools (gated by permission.interrupt):
- task_steer / task_cancel / task_abort (origin=parent).
Human paths:
- POST /session/:id/interrupt (intent steer|cancel|abort, origin=user),
restricted to subagent sessions, gated by the experimental flag, and
rejecting non-running children.
- TUI: esc on a subagent opens a Steer/Cancel/Abort menu, then a reason
prompt; markers render as "... by user". Bound at the session route via a
uniquely-named gather bucket (the keymap gather() caches by name). Visible
interrupt markers render as a distinct "Interrupt" line (tagged via
part.metadata.interrupt), not as user prose.
Whole feature gated by OPENCODE_EXPERIMENTAL_SUBAGENT_INTERRUPT (off by
default): agent tools, HTTP endpoint, and TUI affordance.
Limitations: agent-driven steer/cancel applies to background children only
(a foreground child blocks the parent turn); cancel is boundary-soft (use
task_abort / Abort for a child stuck in a long tool call).

+Cancel a running subagent you spawned, gracefully: it receives your reason, wraps up (summarizes partial work), and stops. Use when a child should stop but you want a clean final result. Requires task_id. After the cancel frame is delivered, the loop force-breaks only at a turn boundary — a child stuck inside a long-running tool call (long bash, big build) will not break until that tool returns, so the wrap-up can take a while. If you need an immediate stop on a child stuck in a long tool, use task_abort instead. Fails if the task_id is not your child or has finished.

+Send a message to the agent that spawned you (your parent), or reply to a subagent you spawned. This is agent-to-agent communication, separate from the human-facing question tool.
+
+Use this tool to:
+1. Ask your parent agent a question mid-task and (by default) wait for an answer.
+2. Send your parent a status update without waiting (set expect_reply: false).
+3. Reply to a subagent that is awaiting your answer (target: "subagent", with its task_id).
+
+Usage notes:
+- target "parent": sends to the agent that spawned you. Fails immediately if you have no parent (e.g. you are the top-level agent) — it never hangs.
+- target "subagent": requires task_id (the id from the task tool's result) of a subagent that is awaiting your reply.
+- expect_reply (default true): when true you block until the parent replies or a timeout elapses, then you continue. When false it is fire-and-forget.
+- Keep round-trips minimal; there is a per-subagent cap.

Subject: [PATCH 13/53] fix(opencode): make agent-message markers incoming-only
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The sender-echo markers duplicated information already shown by the
message tool call itself (✉ Sent to parent / ✉ Replied to subagent sat
right under the visible tool call), and the subagent's "Reply from
parent" marker was written twice — once by the parent's reply branch and
again by the subagent's own send path.
Keep only the incoming markers: the parent sees "✉ Message from
subagent", the recipient subagent sees "✉ Reply from parent", each once.
Drop the now-unused marker direction field.

experimentalS2S runtime flag; s2s_inbox/s2s_token/s2s_allow tables (hand-written migration + Drizzle s2s.sql.ts mirror so fresh-DB CREATE and upgrade paths agree); session_slug_unique migration neutralized to DROP INDEX (slugs are not unique). Store is one statement per method: atomic single-winner claims via UPDATE…RETURNING with drained_at IS NULL / accepted_by IS NULL guards, TTL enforced in the claimToken WHERE clause, and deleteInbox so a delivered row is hard-deleted (distinct from a merely-claimed crashed row). S2SCapsule v1 envelope with forward/back-compat serde and optional sender_name. UUIDv7 generator.

+// from NULL → session-id atomically; a NULL guard in the
+// store's claim makes double-acceptance impossible.
+// s2s_allow — directional session-pair allowlist. Composite PK
+// (session_id, allowed_session_id) makes "is X allowed to
+// talk to Y?" a single SELECT; the PK is naturally
+// directional so we don't need an extra index.

+// * `claimToken` does the same trick on `s2s_token` using
+// `accepted_by IS NULL` as the guard. A second call on an already-
+// accepted token returns None (the RETURNING array is empty).
+// * `s2s_allow` is directional: the composite PK is
+// (session_id, allowed_session_id), so "is X allowed to talk to Y?"
+// is a one-row `SELECT 1 … LIMIT 1`; the reverse direction is its

Per-instance wake poller (C′) lazily forked from SessionPrompt.loop via attach so it captures the live fiber's InstanceRef; runLoop turn-boundary drain (D) of s2s_inbox in-context; 60s reaper that reopens ONLY crashed claims (delivered rows are deleted). LayerNode.group exposes only DIRECT children, so S2SStore/Messaging/SessionStatus are spliced as direct members of every prompt-serving group (app httpapi + control-plane workspace) — this is what made cross-process delivery actually work. marker.ts: shared Marker.render + escapeAttr (escapes " ' for untrusted attribute values so a peer cannot break out of the name=/session= attributes); escape() for element content/visible markers. Slug-decoupled: Messaging.enqueue lazily inits the inbox queue and registerSlug is dropped from the loop, so s2s rides session_id only and the slug registry stays coordinator-messaging-owned. s2s frames carry the sender session name + addressable session_id.

+// Session-to-Session — Task 5 (per-process poller + 60s reaper + V1 idle-wake).
+//
+// This service is the bridge between the cross-process s2s_inbox table
+// (a foreign opencode process writes a row when a session there wants to
+// deliver a message to a session in THIS process) and the in-process
+// Messaging inbox that the runLoop's drain block already knows how to
+// consume. Two responsibilities, both idempotent and rate-bounded:
+//
+// 1. pollOnce (called on a ~2s interval when the experimentalS2S flag
+// is on):
+// a) claim every undrained s2s_inbox row whose target is in this
+// process's local set (claimForSessions is a single SQL
+// UPDATE…RETURNING so the claim is atomic across processes);
+// b) for each claimed row, decode the v1 capsule and enqueue the
+// body into Messaging.inbox tagged with source="sibling-session"
+// (the drain's Task-6 branch reads this tag to choose the
+// framing instead of the in-process marker);
+// c) if the target session is IDLE and has a committed lastUser
+// (so the runLoop will not throw at prompt.ts:1157), wake it by
+// calling SessionPrompt.loop. The wake MUST live here, not on
+// Messaging — adding it to Messaging would create the cycle
+// (Messaging → SessionPrompt → ToolRegistry → Messaging) that
+// breaks the ToolRegistry layer build.
+//
+// 2. reapOnce (called on a 60s interval): reset drained_at to NULL on
+// any claimed row whose claim is older than REAPER_WINDOW_MS. A
+// redelivery after a reaper is a duplicate, but the dedup-on-id in
+// Task 7 makes a redundant redelivery harmless; the simpler
+// time-based reap is preferred over a per-target liveness gate so
+// this service stays small. A future refinement can add a
+// status.get(busy|retry) skip for targets currently running.
+//
+// The poller layer also forks the two loops into the layer's scope,
+// gated on RuntimeFlags.experimentalS2S. The fork is suppressed in tests
+// by passing experimentalS2S: false to the test's RuntimeFlags layer, so
+// the test can drive pollOnce / reapOnce directly without a racing

+// Session-to-Session — C′ wake-poller reproduction (systematic-debugging Phase 4).
+//
+// The LIVE failure: a cross-process s2s message persists to s2s_inbox but the
+// recipient's C′ wake-poller never claims it (drained_at stays NULL). The
+// existing wakeup-spike test only exercises the D-drain (it calls
+// `prompt.loop` AFTER enqueue), and sets experimentalAgentMessaging — NOT
+// experimentalS2S. The C′ fork (gated on experimentalS2S, forked inside
+// SessionPrompt.loop) has ZERO coverage.
+//
+// This test reproduces the real production path:
+// (1) experimentalS2S: true
+// (2) call prompt.loop ONCE → this is the only thing that forks the C′ poller
+// (3) insert a row DIRECTLY into s2s_inbox via the store (simulating the
+// cross-process sender — NOT messaging.enqueue, which is in-process)
+// (4) DO NOT call loop again — the forked C′ poller must claim it on its own
+// (5) assert the row's drained_at is set within a few poll intervals
+//
+// The S2S-DIAG logs in prompt.ts / poller.ts / wake-registry.ts will show
+// exactly where the pipeline breaks.
+//
+// Importing the poller module is REQUIRED: in production app-runtime.ts imports
+// S2SPoller, whose module top-level runs registerWakeBody(wakePollerLoop). The
+// wakeBody() the C′ fork calls is a no-op stub until that registration runs.

+// Session-to-Session — Task 9 (cross-process lifecycle wiring).
+//
+// Validates the three seams that wire the s2s feature into the real
+// session lifecycle so two OC processes can talk:
+//
+// 1. **Seam 1** — the S2SPoller layer subscribes to
+// `SessionV1.Event.Created` and auto-registers a top-level session
+// as local + slug. The subscriber forks into the poller's layer
+// scope and is gated on `experimentalS2S` so s2s is dead code
+// when off. Subagent Created events (parentID set) are NOT
+// claimed here — `tool/task.ts:199` owns that path.
+//
+// 2. **Seam 2** — `SessionPrompt.loop` calls `messaging.registerLocal`
+// + `registerSlug` at entry, gated on `experimentalS2S`. This
+// covers the "existing session re-opened in a fresh process"
+// case. Anti-over-claim invariant: a process only registers a
+// session it actually runs.
+//
+// 3. **Seam 3** — `s2s_allow` + JOIN-based `resolvePeerSlug` lookup.
+// When the peer's slug is NOT in this process's in-process
+// registry (they live in another process), the tool falls back
+// to a DB-resolved consent-scoped JOIN. The JOIN itself proves
+// consent, so the cross-process path does not also require the
+// in-process allow list.
+//
+// Two-live-process simulation is deferred to a real-build check —
+// the bun-test harness runs everything in a single process, and
+// `Session.defaultLayer` captures its own internal
+// `EventV2Bridge.defaultLayer` in a closure (pre-existing pattern).
+// The seam-1 test proves the subscriber end-to-end by publishing
+// `SessionV1.Event.Created` directly through the SAME EventV2Bridge
+// the subscriber forked against. The seam-3 test uses the full
+// base layer from `tool.test.ts` for the S2STool (which requires
+// Truncate + Agent in R).

+// Session-to-Session — Task 5 (per-process poller + 60s reaper + V1 idle-wake).
+//
+// Validates the S2SPoller service end-to-end at the unit level:
+//
+// 1. pollOnce() for a row whose target is in this process's local-set
+// claims it (drained_at set in the s2s_inbox table), enqueues the
+// capsule body into the in-process Messaging inbox tagged with
+// source="sibling-session", then — because the target is idle and has
+// a committed lastUser — wakes it by calling SessionPrompt.loop. The
+// runLoop's drain block (prompt.ts:1216-1262, gated on
+// flags.experimentalAgentMessaging) consumes the inbox at the turn
+// boundary and injects a user message whose non-synthetic part carries
+// a ✉ inbox marker for the foreign sender (slug "peer-z", body
+// "POLL-PAYLOAD-1"). After the loop the inbox is empty and the row
+// is deleted (a second pollOnce returns nothing).
+//
+// 2. pollOnce() for a row whose target is NOT in this process's
+// local-set is left untouched. claimForSessions only returns rows
+// whose target_session_id is in the local set, so no claim SQL fires.
+//
+// 3. A delivered row is hard-deleted by processRow, so a later reapOnce
+// cannot resurrect it — the body is delivered EXACTLY ONCE even across
+// a reap (the M2 regression). The reaper only ever reopens a CRASHED
+// claim (claimed but never deleted), which store.test.ts covers
+// directly.
+//
+// The harness reuses the runLoop plumbing from `wakeup-spike.test.ts` and
+// `tool/coordinator-messaging.test.ts` (stubs for LSP/MCP/Summary, the
+// TestLLMServer + provider cfg) and adds the S2SStore + S2SPoller layers

Subject: [PATCH 25/53] feat(s2s,tui): s2s tool + TUI inbox surface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
s2s tool (invite/accept/msg/leave/relay) gated behind experimentalS2S: single-use 10-min invite tokens, durable bidirectional s2s_allow consent, peers addressed by globally-unique session_id (accept reports the inviter's id). Same-process sends hit the in-process inbox; cross-process persist to s2s_inbox for the recipient's poller. Outbound 50/hr is a SOFT per-process throttle (documented as such in code + s2s.txt); the durable cross-process bound is the recipient INBOX_CAP (exact now that delivered rows are deleted). Registry wires S2SStore into ToolRegistry; message tool gains peer-slug send (message_allow). TUI renders the ✉ inbox marker (session name + id) and the session-list surface.

+// Session-to-Session — Task 7 (the s2s tool).
+//
+// This is the user-facing primitive for cross-session messaging between
+// two SEPARATE top-level opencode sessions (siblings, not parent/child
+// subagents — that path stays on the existing `message` tool). The two
+// sessions live in the same machine (the s2s_inbox table is a per-host
+// SQLite file) and must opt in to each other via an `invite` / `accept`
+// token handshake before they can exchange messages.
+//
+// Commands:
+// - invite — mint a single-use token bound to this session.
+// - accept — consume a peer's token; writes both allow
+// directions and seeds the in-process allow list.
+// - msg — send a body to an allow-listed peer
+// (addressed by the peer's globally-unique
+// session_id); goes in-process when the peer is
+// local and persists to s2s_inbox otherwise.
+// - leave — revoke the allow for a peer (both directions).
+//
+// Addressing is by SESSION_ID, not slug: session.slug is NOT unique
+// (Slug.create is a random adjective-noun pair and starts empty until a
+// title is generated), so a slug cannot address a peer. The durable
+// s2s_allow table is session_id based and is the consent authority. The
+// subagent `message` tool keeps slug addressing — a parent owns its
+// children's slug namespace and guarantees uniqueness there.
+// - relay [id?] — emit a capsule as a copy-pasteable JSON blob
+// (zero-infra fallback; v1 just returns the body
+// in capsule shape so a future Task 8+
+// cross-machine version can pick it up).
+//
+// Dependencies are intentionally narrow: S2SStore + Messaging + Session.
+// The tool does NOT depend on SessionPrompt — the recipient wake is the
+// poller's job, not the sender's (memory-#213 cycle rule: any tool in
+// ToolRegistry must not require SessionPrompt).
+//
+// The cross-process path (`msg` to a non-local peer) goes through the
+// module-local `enqueueExternal` helper, NOT through Messaging's
+// Interface. Putting enqueueExternal on Messaging would have made
+// Messaging.layer require S2SStore in its R, which broke a wave of
+// existing tests that compose Messaging.layer without S2SStore
+// (the `it.instance` harness from `test/lib/effect.ts` layers the
+// test body over the merged layer, and a missing S2SStore in the
+// merged layer's R surfaced as "Service not found" at the first
+// `yield*`). The standalone helper keeps the dependency local.

+Cross-session messaging between two separate top-level opencode sessions (siblings, not parent/child subagents — that path is the `message` tool). The two sessions share the same machine (the s2s_inbox table is a per-host SQLite file) and must opt in to each other via an `invite` / `accept` token handshake before they can exchange bodies. Gated by the `experimentalS2S` runtime flag.
+
+Peers are addressed by their globally-unique session_id (the `ses_...` id), NOT by slug — session slugs are not unique. The `accept` output tells you the peer's session_id to use with `msg`/`leave`.
+
+Usage:
+1. On the inviter session, run `s2s(command:"invite")` to mint a one-shot token. Share that token out-of-band with the peer (chat, paste, etc.).
+2. On the joining session, run `s2s(command:"accept", token:"")` within 10 minutes. This writes the durable allow row in both directions (the consent record). The output reports the peer's session_id.
+3. Either side can now run `s2s(command:"msg", target:"", body:"...")` to send. Same-process peers hit the in-process inbox (tagged `source="sibling-session"` so the runLoop drain renders it as ``); cross-process peers persist a row to `s2s_inbox` that the recipient's poller picks up.
+4. Either side can revoke with `s2s(command:"leave", target:"")`.
+
+Commands:
+- `invite` — mint a token bound to this session.
+- `accept ` — consume a peer's token; writes both allow directions.
+- `msg ` — send a body to an allow-listed peer (addressed by session_id).
+- `leave ` — revoke the allow for a peer.
+- `relay` — emit a capsule as a copy-pasteable JSON blob (zero-infra fallback for future cross-machine delivery).
+
+Usage notes:
+- The token TTL is 10 minutes; a token used after that is rejected.
+- `msg` is bounded two ways, both surfacing as a visible `AbuseError` (never a silent drop): a DURABLE recipient undelivered-row cap (50 — a DB count that holds across restarts and processes; delivered rows are deleted, so this is the real cross-process abuse bound), and a SOFT per-process outbound throttle (~50/hour/sender) that only catches a runaway loop in one process and resets on restart — do not rely on it as a security boundary.
+- Body length is capped at 16000 characters; longer bodies are rejected before delivery.
+- Consent is checked against the durable s2s_allow table (session_id based): you can only `msg` a peer you have invited+accepted. An un-consented target is rejected with a clear error. This works the same whether the peer is in this process or another, and survives a restart.
+- This tool is the cross-process sibling primitive. For parent/child subagent messaging, use `message` instead.

+// Session-to-Session — Task 7: enqueueExternal + the s2s tool.
+//
+// Validates the additive behavior introduced by the s2s tool at
+// the unit level. The test composes a minimum viable layer
+// (Database, S2SStore, Messaging, Session, the S2STool effect,
+// EventV2Bridge) and exercises:
+//
+// 1. S2STool command="invite": mints an s2s_token row bound to
+// the calling session.
+// 2. S2STool command="accept": consumes the token, writes BOTH
+// directions of s2s_allow; a second accept of the same token
+// fails.
+// 3. S2STool command="msg":
+// - to a non-allowed target → tool-level error
+// - to an allow-listed peer that's NOT in-process → row in
+// s2s_inbox (cross-process path through the module-local
+// enqueueExternal helper)
+// 4. S2STool command="leave": deletes both s2s_allow directions.
+// 5. S2STool command="relay": smoke test that the body
+// round-trips through the capsule shape (zero-infra fallback).
+// 6. enqueueExternal:
+// - writes a single s2s_inbox row
+// - the 51st send in an hour trips the AbuseError on the
+// Messaging.AbuseError tag
+// - the same capsule.id twice produces ONE row (per-sender
+// dedup window)
+//
+// The Messaging.enqueueExternal interface method is NOT exercised
+// here because Task 7's enqueueExternal lives as a module-local
+// helper in `src/tool/s2s.ts` (not on the Messaging.Service) — see
+// the file-level comment in that file for the rationale. The cross-
+// process path the tool takes is `S2STool → enqueueExternal`.
+//
+// Mirrors the `in-memory :memory: + Database.layerFromPath` pattern
+// from `test/s2s/store.test.ts`: one in-memory SQLite per file
+// (Bun's `Database(":memory:")` gives one handle per native handle,
+// sharing the layer guarantees every service sees the same tables).

Subject: [PATCH 30/53] fix: adapt subagent interrupt to current dev APIs
- interrupt.ts: remove defaultLayer (deleted at dev), fix node to object form
- interrupt.test.ts: migrate from EventV2Bridge.defaultLayer to LayerNode.compile
- task-interrupt.test.ts: migrate from Layer.mergeAll(defaultLayer) to LayerNode group/compile
- task.test.ts: add Interrupt.node to test group (registry gained the dep)

Subject: [PATCH 33/53] fix: adapt s2s stack to current dev APIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- Rewrite LayerNode.make positional→object form in poller/store
- Add defaultLayer re-exports (raw layer) to 37 modules
- Export layer variable for modules used via .layer access
- Rewrite coordinator-messaging + s2s tests to LayerNode.group pattern
- Switch tests to testEffectShared for Database memoMap sharing
- Add NodePath to runLoopInfra for CrossSpawnSpawner deps
- Create task-event.ts schema + manifest registration
- Regenerate SDK types (task.completed, messaging.peer_sent, s2s.delivered)
- Fix topology-repro.test.ts positional LayerNode.make + buildLayer→compile

Subject: [PATCH 34/53] fix(test): projector node + per-test layer builds for
s2s and coordinator suites
SessionProjector.node added to the s2s/coordinator runLoop harnesses (session
readback needs projection at current dev), the reaper harness gets an explicit
EventV2 layer, the poller runLoop shares the file-level :memory: database via
node replacement, and the fork-fiber-sensitive suites (poller, coordinator
runLoop) build per-test layers (testEffect) instead of a shared memoMap build
so forked poller/drain fibers see the same instances as the test assertions.

Subject: [PATCH 35/53] refactor(test): scope defaultLayer bridge to consumed
modules only
Drops the defaultLayer = layer re-exports from 28 modules nothing consumes;
the 8 that remain (Agent, Config, Session, Truncate, Messaging, S2SStore,
EventV2Bridge, CrossSpawnSpawner) back the three s2s test harnesses that still
compose with Layer.mergeAll. Follow-up: convert those harnesses to LayerNode
and delete the bridge entirely.

Subject: [PATCH 36/53] feat(schema): enrich task.completed payload
Add optional slug, agent, model, variant, elapsedMs, tokens, and cost
fields to the task.completed event. A shared completedPayload helper
reads session metadata and sums tokens/cost from child assistant
messages, used at all 9 publish sites instead of duplicated logic.

Subject: [PATCH 38/53] fix(opencode): harden task.completed enrichment
Wrap completedPayload assembly in Effect.exit so any defect
during session/message reads falls back to the base payload
instead of killing the publish path. Use optional chaining and
nullish defaults for token/cost field access to tolerate missing
or malformed assistant rows. Rewrite test to observe the actual
published event via Deferred + listen instead of relying on
message persistence alone.

+Report a structured result back to the parent/orchestrator session. Call this before your final message when the parent asked you to produce specific output — a verdict, summary, counters, or any free-form JSON object up to 4KB serialized. The result is persisted on your session row and delivered to the parent in the task-completion frame. A root session (no parent) receives a no-op warning instead.

Subject: [PATCH 50/53] fix(opencode): wake handler runs in instance context
with real-path test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Three blocking bugs in wake-on-message (97ae2bd08193), all in the
instance-context/fork wiring:
1. registerWakeHandler was called at layer-build time without yield*,
so the Effect was constructed and discarded. Moved the (now yield*ed)
registration into loop()'s body, which always runs inside a fiber
that has InstanceRef from the caller (HTTP request / CLI run) —
mirroring how the C-prime wake-poller is wired in the same function.
Re-registering on every loop() call is idempotent.
2. Messaging.wakeIfIdle forked the handler via bare Effect.runFork,
which starts a fresh top-level runtime with an empty context and
drops InstanceRef, so the forked prompt.loop died the instant it
touched any InstanceState-scoped service. Replaced both call sites
with attach(handler(target)).pipe(Effect.forkIn(scope)) — attach
re-provides the caller fiber's InstanceRef/WorkspaceRef before the
fork runs, and scope is a new layer-lifetime Scope so the fiber
doesn't leak past Messaging's lifetime.
3. wake.test.ts only exercised spy handlers against a minimal
Messaging-only layer — it never ran the real registration line or a
real prompt.loop, so 786 tests passed over an entirely dead
feature. Added wake-real-path.test.ts, which builds the full
run-loop layer, drives a real prompt.loop, sets a real wake policy,
and enqueues through the real Messaging.enqueue; it asserts the
drain's observable side effect (the ✉ inbox marker) appears without
a second explicit loop() call. Verified red/green against both bugs
individually before landing the fix.

+// Wake-on-message — real-path integration test (Bug 3 fix).
+//
+// wake.test.ts (predicate unit tests) uses spy handlers and a minimal
+// Messaging-only layer; it never builds the real SessionPrompt.layer, never
+// runs the real `messaging.registerWakeHandler((sessionID) => loop(...))`
+// registration line, and never runs a real `prompt.loop`/`runLoop` turn. A
+// registration bug (missing `yield*`) or a context-losing fork (bare
+// `Effect.runFork`) can pass all of wake.test.ts while the feature is
+// completely dead in production — which is exactly what happened.
+//
+// This test builds the full real run-loop layer (mirrors
+// test/s2s/cprime-fork.test.ts's makeRunLoopLayer), drives a session through
+// SessionPrompt.loop for real (which is what registers the wake handler),
+// sets a real wake policy, and enqueues through the REAL Messaging.enqueue —
+// the same call task.ts and the message/s2s tools make in production. The
+// only way the child's transcript picks up the enqueued message without a
+// second explicit `loop()` call is if:
+// (a) registration actually ran (Bug 1), AND
+// (b) the forked handler retained InstanceRef so it could run
+// SessionStatus/SessionRunState/Session (all InstanceState-scoped)
+// without dying (Bug 2).
+// Dropping either fix reproduces the RED failure below (see the fix's
+// commit message / return summary for the before/after run transcripts).

Subject: [PATCH 51/53] test(opencode): update stale event manifest size to 97
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Pre-existing base drift, not introduced by task-signals: the hardcoded
Latest.size assertion was already failing at base 11e2b8a6b (Received 97,
Expected 88) — the fork's accumulated messaging/interrupt/s2s/task events
grew the manifest without updating this constant. Empirically verified
identical size (97) at base and HEAD. Fixed here so the integration
branches go green.
