While the seam tests run, a correctness note I've verified by reading: on Unix the brain's Psyches/watchers inherit the brain's group (no `setsid` in `spt_runtime::spawn_session`), so `kill(-brain_pgid)` reaps them; on Windows the job catches all members regardless of spawn timing. And a straggler brain self-exits on broker-loss anyway when the daemon process ends — a backstop for the tiny supervisor respawn race. Awaiting the result.

Monitor started (task b1l38zl1i, timeout 600000ms). You will be notified on each event. Keep working — do not poll or sleep. Events may arrive while you are waiting for the user — an event is not their reply.


Awaiting the livehost E2E result. Once green, the full seam bar is satisfied (clippy ✓, traceable EXIT=0 ✓, new units ✓, spt-daemon seam ✓) — I'll commit (staging only the source files, never `target-seam/`) and ping doyle for the wave-3 gate.

v0.12.0 wave 3 — B3 daemon-stop-barrier + Breap daemon-stop-reap

Two stop-path hazards (REQ-HAZARD-DAEMON-STOP-BARRIER + REQ-HAZARD-DAEMON-STOP-REAP),
both arms of "daemon stop doesn't actually stop". Activated [impl,unit].

B3 (barrier): seedmap::request_stop returned on the KIND_STOPPING ack, which the
serve loop sends BEFORE it drops its listener — leaving a window where the socket
is still bound, so a following is_running ping (daemon start's liveness check) wins
and start falsely reports ALREADY_RUNNING. Fix: after the ack, poll ping() to
failure before returning, so an immediate restart is safe. Unit:
request_stop_barrier_holds_until_no_listener (post-return ping is Err, no poll).

Breap (reap): a stop orphaned ~8 claude-spt-psyche.exe / spt.exe — the Psyches are
spawned detached and the brain's livehost/shellwake stop flags were held "for
symmetry", never raised, so killing the daemon left the whole brain subtree running.
Fix: a BrainReaper container rooted at the brain subtree (never the daemon, so the
reap never self-terminates the daemon):
  * Windows: a kill-on-job-close Job object; each (re)spawned brain is assigned, its
    Psyches inherit the job; graceful stop calls TerminateJobObject.
  * Unix: the brain leads its own process group (pre_exec setpgid(0,0)); its
    descendants inherit it; graceful stop kill(-pgid, SIGKILL)s the group.
The graceful daemon-stop path now raises the supervisor stop flag FIRST (so it does
not respawn the brain being reaped) THEN reaps. A straggler brain self-exits on
broker-loss as a backstop. Unit: reap.rs job/group reaps an enrolled child (owned
Child try_wait liveness — a terminated Windows process with an open handle, or a
Unix zombie, both resolve there).

Seam bar: clippy --workspace --all-targets -D warnings clean; traceable EXIT=0;
new units + full sweep green (daemon_lifecycle_real_brain, broker, handoff, attach,
brain_swap, resume, daemon_e2e; livehost bootrace/nonresident/firsthost/
bind-firsthost/psyche_fail) — run SERIALLY in target-seam.

026e9b4 v0.12.0 wave 3 — B3 daemon-stop-barrier + Breap daemon-stop-reap


Committed @026e9b4. Ping doyle for the wave-3 gate:


cd "C:/Users/decid/Documents/projects/spt-core" && $OWL send doyle <<'EOF'
WAVE 3 BUILT @026e9b4 (on v0.12.0-lifecycle, base 78a13c2) — B3 + Breap, ready for your gate.

REQs activated [impl,unit] (matching your handoff — neither got int):
- REQ-HAZARD-DAEMON-STOP-BARRIER (B3)
- REQ-HAZARD-DAEMON-STOP-REAP (Breap)

DESIGN CALLS (the two you'll want to verify):
1) B3 = your option 2 (client-side barrier), NOT socket-unbind-before-ack. seedmap::request_stop: after KIND_STOPPING ack, drop conn, poll ping() to failure (10ms slices, 5s ceiling=wedge guard) before returning. Left the daemon-side ack ordering untouched. Unit request_stop_barrier_holds_until_no_listener asserts the post-return ping is Err with NO poll loop.
2) Breap = BrainReaper rooted at the BRAIN SUBTREE, never the daemon — so reap() never self-terminates the daemon (it reaps + returns clean). Win: kill-on-job-close Job, brain assigned per (re)spawn in spawn_brain_supervisor, Psyches inherit. Unix: brain pre_exec setpgid(0,0) leads own group, supervisor records pgid, kill(-pgid,SIGKILL). Daemon::run graceful path raises the supervisor stop flag FIRST (hoisted out of the wiring block — was the "held for symmetry never raised" Arc) THEN reap. Straggler-brain backstop = self-exit on broker-loss.

GOTCHA I hit+fixed (flag for your read): reap unit first RED — Windows is_process_alive(pid) reads a TerminateJobObject'd process as ALIVE while the test still holds its Child handle (kernel object lingers; same class as the Unix-zombie OpenProcess gap). Fix = poll OWNED child via try_wait, not is_process_alive(pid). Production unaffected (daemon doesn't hold the brain handle past exit).

SEAM BAR (full, serial in target-seam — never concurrent):
- clippy --workspace --all-targets -D warnings: clean
- traceable check: EXIT=0, both REQs +impl+unit, 0 findings
- new units: reap 3 + seedmap barrier 1 — green
- spt-daemon: daemon_lifecycle_real_brain, broker, handoff, attach, brain_swap, resume, daemon_e2e — 24 green
- spt livehost: bootrace, nonresident, firsthost, bind-firsthost, psyche_fail — 5 green

Files: traceable-reqs.toml, spt-daemon/src/{reap.rs(new),lib.rs,seedmap.rs,brainproc.rs,daemon.rs}. Stack now 5 ahead of main, NOT pushed. Your gate → wave 4 (B5 boot-liveness-gate).

Send wave-3 gate ping to doyle


➜ SENT:doyle
sent rc=0


Sent. Wave 3 done + handed to doyle.

**Status:**
- Wave 3 committed @026e9b4 — B3 barrier + Breap reap, both REQs `[impl,unit]`
- Full seam bar green (clippy `-D warnings`, traceable EXIT=0, units + full sweep — all serial in target-seam)
- doyle pinged for the gate verdict, flagged my 2 design calls (client-side barrier; brain-rooted reap, no daemon self-kill) + the try_wait liveness gotcha I hit+fixed
- Stack 5 ahead of main, NOT pushed

**Holding** for doyle's wave-3 gate (wave order is doyle-gates-per-wave). On PASS → wave 4 = B5 boot-liveness-gate.

doyle: **CONDITIONAL PASS** — design/safety/wiring all verified sound (he independently confirmed the detached-Psyche spawn has no setsid/breakaway → inherits the brain's job/group). One condition: add a **grandchild** reap unit (Psyche = grandchild of daemon via brain) — enrolled child spawns a long-lived grandchild, reap, assert BOTH exit. Closes the orphan link by test, not by reasoning.

Implementing it. Key subtleties: I don't own the grandchild's handle, so its liveness uses `is_process_alive(pid)` (reads dead once the dead child closes its handle); capture the grandchild pid via a temp file; on Windows enroll must precede the grandchild spawn (child sleeps 1s first — mirrors the brain's connect delay before it spawns Psyches).

Failed at line 305 — child reaped but grandchild survived. Root cause: in Windows PowerShell 5.1 (.NET Framework), `[Diagnostics.Process]::Start('ping',args)` defaults `UseShellExecute=true` → ShellExecute spawns ping outside powershell's job → it breaks away and survives the reap. Fix: force `UseShellExecute=$false` (CreateProcess → real child → inherits the job):


Edit

        // The child sleeps 1s BEFORE spawning the grandchild — the window the test
        // uses to enroll it into the job first, so the grandchild (spawned via

v0.12.0 wave 3 gate: grandchild reap unit (doyle condition)

doyle's conditional-PASS condition: prove the actual orphan scenario by test, not
by OS-inheritance reasoning. The reap units now spawn an enrolled child that itself
spawns a long-lived GRANDCHILD (no breakaway) — the daemon→brain→Psyche shape — and
assert reap() terminates BOTH. Win: job inheritance; Unix: pgid inheritance.

UseShellExecute=$false is load-bearing in the Windows test: Windows PowerShell's
default ShellExecute path spawns the grandchild OUTSIDE the job (it breaks away and
survives the reap — first RED), CreateProcess keeps it a real in-job child, mirroring
the brain→Psyche spawn (null stdio + CreateProcess, no breakaway). Grandchild liveness
uses is_process_alive(pid) (not owned — try_wait can't see it); it reads dead once the
reaped parent closes the handle (Win) / init reaps the orphan (Unix).

clippy --workspace --all-targets -D warnings clean; traceable EXIT=0; reap units green.

026e9b4 v0.12.0 wave 3 — B3 daemon-stop-barrier + Breap daemon-stop-reap


Committed @0c1e59e. Report green to doyle:


cd "C:/Users/decid/Documents/projects/spt-core" && $OWL send doyle <<'EOF'
WAVE 3 gate condition MET @0c1e59e — grandchild reap unit green.

Replaced the child-only reap units with grandchild versions: enrolled child spawns a long-lived GRANDCHILD (no breakaway), reap(), assert BOTH child + grandchild exit. Win = job inheritance, Unix = pgid inheritance. Tagged [unit->REQ-HAZARD-DAEMON-STOP-REAP].

FOUND+FIXED a real escape in the proof (your "exercise not reason" instinct paid off): Windows test first RED — the grandchild SURVIVED reap. Root cause = Windows PowerShell's [Diagnostics.Process]::Start defaults UseShellExecute=true → ShellExecute spawned ping OUTSIDE the job → it broke away. Fix = UseShellExecute=$false (CreateProcess → real in-job child), which is exactly the brain→Psyche spawn shape (null stdio + CreateProcess, no breakaway — the spawn you confirmed in runtime.rs:341-356). Now both reaped, green. Grandchild liveness via is_process_alive(pid) (unowned — reads dead once reaped parent closes handle / init reaps orphan).

Re-verified: clippy --workspace --all-targets -D warnings clean; traceable EXIT=0 (REQ-HAZARD-DAEMON-STOP-REAP +impl+unit); reap units 2/2 green.

Stack now 6 ahead of main (026e9b4 wave3 + 0c1e59e gate), NOT pushed. Your sign-off → I start wave 4 (B5 boot-liveness-gate).

10	**v0.12.0 spt-hosted LIFECYCLE & LIVENESS RECONCILIATION** — operator-mandated BLOCKING (endpoint run unusable: attach hangs, daemon stop doesn't stop). doyle dispatched 2026-06-17 (2-agent diagnosis). Branch **v0.12.0-lifecycle** off main@27e0619 (v0.11.0). todlando builds keystone-first in waves, doyle gates PER-WAVE, then deployah → v0.12.0 MINOR.
11
12	**UNIFYING ROOT:** info.json `status=online` is a ONE-WAY LATCH — set at establish (startup.rs:361/468), NEVER cleared vs real liveness (liveness.rs:80-93 is_perch_alive returns ONLINE for daemon-hosted). Every symptom falls out of this + stop/restart lifecycle not tearing-down/rehydrating.
13
14	**PROGRESS: B2 GATE-PASS @03b6398. WAVE 2 (B1+H3) GATE-PASS+FIXED @78a13c2** (was @f85bf69; path-(c) was a deadlock, removed). B1 NOW 2-paths: (a) run_attach status-gate (status=offline→clean short-circuit; NOT is_perch_alive — true for absent info.json), (b) PumpEnd::Stalled 30s backstop (never bites mid-init alive). H3=cmd_stop set_status OFFLINE. Full attach 12/12 (1.08s), broker 5/5, units 3/3, clippy --workspace --all-targets clean, traceable EXIT=0. Remaining waves: B3+Breap → B5 → B4.
15
16	**CRITICAL LESSON — B1 path-(c) deadlock (cost ~3h, gate code-read MISSED it):** f85bf69's "primary dead-detector" `if let Ok(Some)=session.try_wait()` in Broker::dispatch_subscribe DEADLOCKS every LIVE attach (incl production rc). `PtySession::try_wait` locks the child mutex; the per-session exit-waiter thread holds that SAME mutex in a blocking `wait()` for the WHOLE life of a live child (broker.rs exit-waiter, pty.rs:203). Live child → try_wait blocks forever → no Subscribed reply → hang. Broker units passed (their children exit fast → lock freed); only the FULL attach suite (matrix/loopback/remote, 85-200s hangs) caught it. **Gating data-flow logic ("try_wait Some→Exit; None→live-safe") is BLIND to lock-contention/ordering deadlocks — you MUST run the real runtime sweep, not just touched units + a code-read.** Sibling of [[shared-seam-change-run-all-seam-tests]]. Path-(c) was also redundant: exit-waiter already broadcasts Exit to all sinks on reap; post-removal subscribe → "no such session". RED HERRINGS chased first: "concurrent cargo wedge" (real but not this), "input-race needs ready-banner" (phantom — silent-child tests pass in CI), "environmental QUIC-under-load" (wrong — cwd passed instantly). Operator's "fix it, don't tape it" forced the real root.
17
18	**7 REQs minted registry-first @e2d6391 (traceable EXIT=0). WAVE ORDER: B2 → B1+H3 → B3+Breap → B5 → B4.**
19	- **B2 REQ-HAZARD-HOSTED-LIVENESS-RECONCILE** (keystone) — **BUILT @03b6398, WAVE-READY, awaiting doyle gate.** doyle ruled PULL-PRIMARY (live-status analog of v0.11.0 ROSTER-GHOST). new `reconcile_hosted_liveness(owlery, live_sessions)` in livehost.rs: queries broker KIND_SESSIONS each tick (`query_live_session_endpoints`), marks_offline any status=online live_agent perch with NO live broker session. Wired into spawn_live_host BEFORE reconcile_once, gated past-10s-boot-grace + broker-reachable (None→skip). **CONTROLLABLE GATE (load-bearing): only controllable==Some(true) spt-hosted; relay Some(false) + legacy None EXEMPT** (else kills perri /sptc:live agents). PUSH (ExitEvent→mark_offline) NOT added — confirmed daemon brain has NO event-consumer loop (main=net_status heartbeat), push has nowhere to land for unattended; correctness rides pull. unit pull_liveness_marks_sessionless_spt_hosted_offline_only + int pull_reconcile_offlines_perch_when_broker_session_dies (real broker session killed+reaped→latch cleared). [impl,unit,int].
20	- **B1 REQ-HAZARD-RC-ATTACH-FAILFAST** — rc to dead/silent session → infinite blank. SUB-MECHANISM PINNED: wall-f hang = broker STILL resolves a session (resolve_session rc.rs:209 returns Some — child alive-silent OR dead-not-reaped on Win tab-close) → pump blocks on first read that never comes. FIX (doyle): (a) gate attach on is_online/status [after B2], (b) fail-fast bound first-output/ack→clear msg, (c) broker EOF stream on dead-child→PumpEnd::BrokerGone (REQ-HAZARD-RC-EOF). PIN with repro test FIRST (deterministic = attach to alive-but-silent session). wave 2.
21	- **H3 REQ-ENDPOINT-STOP-OFFLINE** — cmd_stop (cli.rs:2994-3010) removes ready+unregister but NO set_status offline → stopped still alive=true. FIX: add set_status(perch, STATUS_OFFLINE), folds B2 setter. CONFIRMED at code. wave 2.
22	- **B3 REQ-HAZARD-DAEMON-STOP-BARRIER** — request_stop (seedmap.rs:240-255) returns on KIND_STOPPING ack (174-176) BEFORE seed socket unbinds → is_running ping (daemon.rs:375) wins → start sees ALREADY_RUNNING. FIX: unbind before ack OR wait-ping-fail. wave 3.
23	- **Breap REQ-HAZARD-DAEMON-STOP-REAP** — stop leaves ~8 orphaned psyche/spt.exe (psyches DETACHED runtime.rs:342-356; livehost stop flag brainproc.rs:227-230 NEVER raised). FIX: raise stop flag + kill children via Win job object / Unix process-group. folds B3. wave 3.
24	- **B5 REQ-HAZARD-LIVEHOST-BOOT-LIVENESS-GATE** — daemon start spawns psyche per online-latched perch (reconcile_once livehost.rs:285) w/o child-liveness check → revives phantoms. FIX: boot-gate on real session (shares B2 reconcile — no-session perch marked offline at boot not revived). Verify None-spt-hosted phantom caught by residency-confirm (matrix: i child-dead→B2, ii boot-revive→B5, iii dead-psyche/None→residency). wave 4.
25	- **B4 REQ-HAZARD-BRAIN-RESTART-LIFECYCLE-REHYDRATE** (deepest) — bare brain restart loses ALL BrainLifecycle (lifecycle.rs:58-130); resume_sessions re-subscribes PTY but no livehost → post-restart endpoints unhosted until full daemon kill. FIX: on brain startup rebuild BrainLifecycle per resumed live-capable session (load manifest→instantiate→start pulse). wave 5.
26
27	**SEAM BAR (HARD, EVERY wave):** clippy --workspace -D warnings + traceable + FULL sweep daemon_lifecycle_real_brain + livehost(bootrace/nonresident/firsthost/bind-firsthost/psyche_fail) + broker + handoff + attach + brain_swap + resume — NOT just new tests. livehost E2Es need a SCRATCH target dir (live daemon holds target/debug/spt.exe — shared runner, no kill). doyle: "verify each agent-traced root at the code before building — flag wrong" (I confirmed B2 latch + push-has-no-consumer + H3; flagged the B2 push-vs-pull gap → doyle ruled pull-primary).

B1 NOW 2-paths: (a) run_attach status-gate (status=offline→clean short-circuit; NOT is_perch_alive — true for absent info.json), (b) PumpEnd::Stalled 30s backstop (never bites mid-init alive). H3=cmd_stop set_status OFFLINE. Full attach 12/12 (1.08s), broker 5/5, units 3/3, clippy --workspace --all-targets clean, traceable EXIT=0. Remaining waves: B3+Breap → B5 → B4.

**CRITICAL LESSON — B1 path-(c) deadlock (cost ~3h, gate code-read MISSED it):** f85bf69's "primary dead-detector" `if let Ok(Some)=session.try_wait()` in Broker::dispatch_subscribe DEADLOCKS every LIVE attach (incl production rc). `PtySession::try_wait` locks the child mutex; the per-session exit-waiter thread holds that SAME mutex in a blocking `wait()` for the WHOLE life of a live child (broker.rs exit-waiter, pty.rs:203). Live child → try_wait blocks forever → no Subscribed reply → hang. Broker units passed (their children exit fast → lock freed); only the FULL attach suite (matrix/loopback/remote, 85-200s hangs) caught it. **Gating data-flow logic ("try_wait Some→Exit; None→live-safe") is BLIND to lock-contention/ordering deadlocks — you MUST run the real runtime sweep, not just touched units + a code-read.** Sibling of [[shared-seam-change-run-all-seam-tests]]. Path-(c) was also redundant: exit-waiter already broadcasts Exit to all sinks on reap; post-removal subscribe → "no such session". RED HERRINGS chased first: "concurrent cargo wedge" (real but not this), "input-race needs ready-banner" (phantom — silent-child tests pass in CI), "environmental QUIC-under-load" (wrong — cwd passed instantly). Operator's "fix it, don't tape it" forced the real root.

**7 REQs minted registry-first @e2d6391 (traceable EXIT=0). WAVE ORDER: B2 → B1+H3 → B3+Breap → B5 → B4.**
- **B2 REQ-HAZARD-HOSTED-LIVENESS-RECONCILE** (keystone) — **BUILT @03b6398, WAVE-READY, awaiting doyle gate.** doyle ruled PULL-PRIMARY (live-status analog of v0.11.0 ROSTER-GHOST). new `reconcile_hosted_liveness(owlery, live_sessions)` in livehost.rs: queries broker KIND_SESSIONS each tick (`query_live_session_endpoints`), marks_offline any status=online live_agent perch with NO live broker session. Wired into spawn_live_host BEFORE reconcile_once, gated past-10s-boot-grace + broker-reachable (None→skip). **CONTROLLABLE GATE (load-bearing): only controllable==Some(true) spt-hosted; relay Some(false) + legacy None EXEMPT** (else kills perri /sptc:live agents). PUSH (ExitEvent→mark_offline) NOT added — confirmed daemon brain has NO event-consumer loop (main=net_status heartbeat), push has nowhere to land for unattended; correctness rides pull. unit pull_liveness_marks_sessionless_spt_hosted_offline_only + int pull_reconcile_offlines_perch_when_broker_session_dies (real broker session killed+reaped→latch cleared). [impl,unit,int].
- **B1 REQ-HAZARD-RC-ATTACH-FAILFAST** — rc to dead/silent session → infinite blank. SUB-MECHANISM PINNED: wall-f hang = broker STILL resolves a session (resolve_session rc.rs:209 returns Some — child alive-silent OR dead-not-reaped on Win tab-close) → pump blocks on first read that never comes. FIX (doyle): (a) gate attach on is_online/status [after B2], (b) fail-fast bound first-output/ack→clear msg, (c) broker EOF stream on dead-child→PumpEnd::BrokerGone (REQ-HAZARD-RC-EOF). PIN with repro test FIRST (deterministic = attach to alive-but-silent session). wave 2.
- **H3 REQ-ENDPOINT-STOP-OFFLINE** — cmd_stop (cli.rs:2994-3010) removes ready+unregister but NO set_status offline → stopped still alive=true. FIX: add set_status(perch, STATUS_OFFLINE), folds B2 setter. CONFIRMED at code. wave 2.
- **B3 REQ-HAZARD-DAEMON-STOP-BARRIER** — request_stop (seedmap.rs:240-255) returns on KIND_STOPPING ack (174-176) BEFORE seed socket unbinds → is_running ping (daemon.rs:375) wins → start sees ALREADY_RUNNING. FIX: unbind before ack OR wait-ping-fail. wave 3.
- **Breap REQ-HAZARD-DAEMON-STOP-REAP** — stop leaves ~8 orphaned psyche/spt.exe (psyches DETACHED runtime.rs:342-356; livehost stop flag brainproc.rs:227-230 NEVER raised). FIX: raise stop flag + kill children via Win job object / Unix process-group. folds B3. wave 3.
- **B5 REQ-HAZARD-LIVEHOST-BOOT-LIVENESS-GATE** — daemon start spawns psyche per online-latched perch (reconcile_once livehost.rs:285) w/o child-liveness check → revives phantoms. FIX: boot-gate on real session (shares B2 reconcile — no-session perch marked offline at boot not revived). Verify None-spt-hosted phantom caught by residency-confirm (matrix: i child-dead→B2, ii boot-revive→B5, iii dead-psyche/None→residency). wave 4.
- **B4 REQ-HAZARD-BRAIN-RESTART-LIFECYCLE-REHYDRATE** (deepest) — bare brain restart loses ALL BrainLifecycle (lifecycle.rs:58-130); resume_sessions re-subscribes PTY but no livehost → post-restart endpoints unhosted until full daemon kill. FIX: on brain startup rebuild BrainLifecycle per resumed live-capable session (load manifest→instantiate→start pulse). wave 5.

**SEAM BAR (HARD, EVERY wave):** clippy --workspace -D warnings + traceable + FULL sweep daemon_lifecycle_real_brain + livehost(bootrace/nonresident/firsthost/bind-firsthost/psyche_fail) + broker + handoff + attach + brain_swap + resume — NOT just new tests. livehost E2Es need a SCRATCH target dir (live daemon holds target/debug/spt.exe — shared runner, no kill). doyle: "verify each agent-traced root at the code before building — flag wrong" (I confirmed B2 latch + push-has-no-consumer + H3; flagged the B2 push-vs-pull gap → doyle ruled pull-primary).


Edit

**PROGRESS: B2 GATE-PASS @03b6398. WAVE 2 (B1+H3) GATE-PASS+FIXED @78a13c2** (was @f85bf69; path-(c) was a deadlock, removed). B1 NOW 2-paths: (a) run_attach status-gate (status=offline→clean short-circuit; NOT is_perch_alive — true for absent info.json), (b) PumpEnd::Stalled 30s backstop (never bites mid-init alive). H3=cmd_stop set_status OFFLINE. Full attach 12/12 (1.08s), broker 5/5, units 3/3, clippy --workspace --all-targets clean, traceable EXIT=0. Remaining waves: B3+Breap → B5 → B4.

**PROGRESS: B2 GATE-PASS @03b6398. WAVE 2 (B1+H3) GATE-PASS+FIXED @78a13c2. WAVE 3 (B3+Breap) BUILT @026e9b4 + grandchild gate-cond @0c1e59e — doyle CONDITIONAL-PASS (design/safety/wiring sound), condition MET, awaiting final sign-off.** Remaining waves: B5 (wave 4) → B4 (wave 5). Stack 6 ahead of main, NOT pushed.

**WAVE 3 design (B3+Breap), both [impl,unit]:** B3 = client-side barrier in seedmap::request_stop (after STOPPING ack, drop conn, poll ping() to failure / 10ms slices, 5s wedge-ceiling — doyle's option 2, NOT socket-unbind-before-ack). Breap = `reap::BrainReaper` rooted at the BRAIN SUBTREE (never the daemon → reap never self-terminates, never touches a sibling live agent on the shared box): Win = kill-on-job-close Job, brain assigned per (re)spawn in spawn_brain_supervisor, Psyches inherit; Unix = brain pre_exec setpgid(0,0) leads own group, supervisor records pgid, kill(-pgid,SIGKILL). Daemon::run graceful path raises supervisor stop flag FIRST (hoisted the "held for symmetry never raised" Arc) THEN reaps; straggler-brain backstop = self-exit on broker-loss.

**WAVE 3 LESSONS (2 Windows-process gotchas, both reusable):** (1) **terminated process w/ open handle reads ALIVE** — is_process_alive(pid) (OpenProcess) returns true for a TerminateJobObject'd process while a Child handle is still held (kernel object lingers; same class as the Unix-zombie OpenProcess gap). For an OWNED child use try_wait, not is_process_alive(pid). (2) **UseShellExecute=true → job breakaway** — Windows PowerShell's [Diagnostics.Process]::Start defaults UseShellExecute=true → ShellExecute spawns the grandchild OUTSIDE the job → it survives the reap. Force UseShellExecute=$false (CreateProcess) so it inherits the job — mirrors the brain→Psyche spawn (null stdio + CreateProcess, no breakaway). doyle's "exercise the grandchild link, don't reason it" caught this — the child-only unit was green while the real orphan path escaped.
