# /spt:send

All commands use `$OWL` env var, auto-injected by the plugin's SessionStart hook. If commands fail with "command not found", restart the Claude Code session so the SessionStart hook re-runs.

> **Identity auto-detection:** Your identity is auto-detected from your session. Pass your ID explicitly only if auto-detection fails.

## Messaging Command Reference

Both commands read the message body from **stdin** (pipe or heredoc).

```bash
# send -- fire-and-forget to a target (use when you have your own perch)
$OWL send <target> <<'EOF'
message body
EOF

# send --reply-to -- respond to whoever messaged you
$OWL send --reply-to <sender> [your-id] <<'EOF'
response body
EOF

# ask -- deliver + create ephemeral reply perch + poll for reply (use when you have NO perch)
$OWL ask <target> [from] <<'EOF'
message body
EOF
```

If auto-detection fails, pass your ID explicitly: `$OWL send <target> <your-id>`, `$OWL send --reply-to <sender> <your-id>`, `$OWL ask <target> <impromptu-id>`.

**When to use which:**
- **`send`**: You already have a listener. Fire-and-forget, no reply perch created.
- **`send --reply-to`**: You received a message and want to respond. `from` is auto-set from the original sender.
- **`ask`**: You have no listener. Creates a temporary perch, delivers, then polls for the reply.

## Pre-checks

- If `<target>` matches this agent's own listener ID, refuse. Self-sends create loops.
- All send/reply-to/ask commands verify the target is alive automatically.

## If you already have a listener

Just send -- no reply perch needed. Run **not** in background:

```bash
$OWL send <target> <<'EOF'
<msg>
EOF
```

## If you have no listener

The `ask` subcommand creates an ephemeral reply perch, delivers, and polls for the reply. Run with `run_in_background: true` (or `false` for `--block`):

```bash
$OWL ask <target> <<'EOF'
<msg>
EOF
```

## On response

**Important:** If you have an active listener perch, always launch Agent tool calls with `run_in_background: true`. Foreground agents block your poll loop -- no messages (including replies to your send) can be delivered until the agent finishes.

When the response arrives, present it to the user. Responses arrive via one of three paths:
- **Background interject** -- the `$OWL ask` background task completes with the reply.
- **Inline** -- if you used `--block`, the reply prints directly.
- **Hook-injected XML** -- if you are mid-tool-call, the reply appears as `<owl_messages>` XML in your tool call context. The `from` attribute is the sender.

ARGUMENTS: todlando GATE RULING — cut option 1 (env-tunable TEST watchdog). Mechanism pin ACCEPTED, verified vs source (both gates hardcode recv_timeout(30s): JRNL_FLAKE inject_control_wedge.rs:733, PASTE_FLAKE :2007; SPT_REGISTRY_BUSY_TIMEOUT_MS precedent confirmed @7c09819).

On my "don't widen" flag — it's SATISFIED not overruled: a real paste-wedge blocks FOREVER → trips any finite watchdog, so 30→120s in CI loses zero wedge detection; only the 30-120s serviced-late band drops, which is pure cross-run-starvation noise (worst real ack=3.8s pegged-CPU). My caution was about masking a PRODUCT slow-path; your pin proves none exists (sole elastic bound=request_attach net_open_stream ack ≤3.8s). So widening the TEST wall-clock is matched-to-mechanism. Option 2 = harden product code for a test-rig artifact (wrong layer, reject pre-publish). Option 3 = ship-around (operator ruled out).

CUT CONDITIONS (all binding for gate-pass):
1. DEFAULT stays 30s. Local/non-CI run keeps tight real-wedge catch. Env knob (SPT_ATTACH_GATE_WATCHDOG_MS) only relaxes when CI exports it.
2. BOTH gates get the knob (JRNL_FLAKE :733 AND PASTE_FLAKE :2007) — single shared helper to read the env, not two copies.
3. Fix the source-attribution print: the recv_elapsed>=29s 'WATCHDOG-DEFAULT' label is hardcoded — derive it from the configured watchdog (e.g. >= watchdog-1s) so the diagnostic stays truthful at 120s.
4. CI export lives in the matrix workflow env, mirror SPT_REGISTRY_BUSY_TIMEOUT_MS placement (=120000, matches your proposal). Not a per-test hack.
5. Keep the JRNL_FLAKE/PASTE_FLAKE source-attribution eprintln (cheap, load-bearing for next triage). DROP any heavyweight repro-only instrumentation you left uncommitted — confirm what stays.
6. Gate stays non-vacuous: still asserts subscribed=true AND got_output=true. Widening only grants the ack wall-clock, never relaxes the assertion.

Cut it, re-run x3 clean (and DON'T stack 10 concurrent matrices on hfenduleam this time — that load was the trigger). Green x3 → I gate-read the diff → publish. Go.

Send gate ruling to todlando


➜ SENT:todlando


Ruling sent to todlando.

**Gate decision logged:** option 1 — env-tunable TEST watchdog (`SPT_ATTACH_GATE_WATCHDOG_MS`, default 30s tight / CI 120s), 6 binding cut-conditions. My "don't widen" flag reconciled as satisfied: widening the test wall-clock loses zero product-wedge detection (wedge=infinite > any finite watchdog); only drops external-starvation noise.

**Now waiting on:** todlando cuts → x3 clean matrix (without self-stacking concurrent runs) → I gate-read the diff → v0.13.0 publish.

Ball in todlando's court. Will pick up on the cut.

    test(inject-wedge)+ci: env-tunable attach-gate watchdog (default-tight / CI-generous) for the Windows cross-run-starvation flake

    Matrix run 2/3 hit a Windows p0_paste subscribed=false. Pinned (repro-first, local
    Windows under load): the concurrent-attach gates' SOLE elastic bound is request_attach
    (its journaled net_open_stream ack); subscribed=false = the 30s result_rx watchdog
    defaulting (false,false) when that ack outran 30s. request_attach is <=3.8s even under
    pegged CPU -> the >30s needs cross-run SCHEDULER STARVATION (the ~1200-test pool + many
    concurrent matrix runs on the shared self-hosted box), not a product wedge. Serviced-
    but-late, not a wedge (a real wedge blocks FOREVER). net_stream_subscribe is fire-and-
    forget; the "2s pump deadline" hypothesis did not apply (attacher uses plain cold_start).

    Fix (doyle gate ruling, option 1, all 6 cut conditions):
    1. DEFAULT stays 30s — a real paste-wedge blocks forever so it trips any finite
       deadline; the gate keeps catching regressions locally / by default.
    2. ONE shared helper attach_gate_watchdog() reads SPT_ATTACH_GATE_WATCHDOG_MS; BOTH
       gates (a_journaled + p0_paste) use it (no two copies).
    3. Source-attribution label (channel vs WATCHDOG-DEFAULT) derives from the CONFIGURED
       watchdog (>= watchdog-1s), truthful at 30s OR 120s.
    4. CI exports SPT_ATTACH_GATE_WATCHDOG_MS=120000 as a job-level env on the matrix test
       job (.github/workflows/ci.yml), not a per-test hack; mirrors the
       SPT_REGISTRY_BUSY_TIMEOUT_MS precedent. Local stays tight.
    5. Kept ONLY the cheap JRNL_FLAKE/PASTE_FLAKE MAIN-recv source-attribution eprintln;
       dropped the heavyweight per-step repro instrumentation.
    6. Gate stays non-vacuous: still asserts subscribed=true AND got_output=true. The knob
       grants ack wall-clock only, never relaxes the assertion.

    Verified: both gates pass at default 30s (recv ~16ms, source=channel); with the knob
    forced to 1ms the gate FAILS (false,false, source=WATCHDOG-DEFAULT) -> proves the knob
    wires + a real wedge is still caught. clippy -p spt-daemon --all-targets -D warnings clean.

Gate-read complete. Verdict: **PASS.**

Diff verified vs all 6 conditions:
1. **Default 30s** — `attach_gate_watchdog()` returns `from_secs(30)` on both Err AND parse-fail. ✓
2. **One shared helper** — `attach_gate_watchdog()` called at both `:733` (a_journaled) + `:2010` (p0_paste), no copies. ✓
3. **Label derives from config** — `recv_elapsed >= watchdog.saturating_sub(1s)`, truthful at 30s/120s; `saturating_sub` safe at the 1ms verification too. ✓
4. **CI env job-level** — `SPT_ATTACH_GATE_WATCHDOG_MS: "120000"` on the matrix job, beside-precedent, commented. ✓
5. **Only MAIN-recv eprintln kept** — diff adds just the two MAIN-recv attribution lines; no per-step. ✓
6. **Non-vacuous** — hunks touch only the recv_timeout region; `subscribed`/`got_output` asserts (`:786+`, `:2065+`) untouched. ✓

Zero product diff — test + CI only. Correct layer (harden test vs starvation, not product). Verification evidence solid: knob=1ms → FAIL(false,false, WATCHDOG-DEFAULT) proves wiring + real-wedge still caught at tight default.

6. Non-vacuous — hunks touch only the recv_timeout region; subscribed/got_output asserts (:786+/:2065+) untouched.

ZERO product diff = correct layer (harden the TEST vs starvation, not the product). Verification (1ms->FAIL, WATCHDOG-DEFAULT) proves the knob wires + tight default still catches a real wedge. Approved.

GO: re-run matrix x3 on delivery-control (73ff016), serialized — NO concurrent matrices on hfenduleam. Green x3 -> I confirm the runs -> operator publish-confirm -> deployah v0.13.0.

b4 sync = DEFER. Cosmetic only, and the operator is mid-flight in the main worktree (ADR-0023/c84daff). Don't churn it now; fold b4 up to the watchdog fix POST-publish via a throwaway worktree. Ship branch is delivery-control. Ping on x3 green.
EOF

Send diff gate-read PASS to todlando


Gate-read **PASS** sent. Diff is clean — test+CI only, zero product diff, all 6 conditions verified in-diff.

**Now:** todlando re-runs matrix x3 serialized on delivery-control (73ff016). Green x3 → I confirm runs → operator publish-confirm → deployah cuts v0.13.0.

b4 sync deferred (cosmetic, post-publish, operator mid-flight in main worktree).

Standing by for x3 green.


you re-run matrix.


Operator says I drive the x3 runs. Serialized (no concurrent on hfenduleam). First — inspect CI triggers + PR#26 state to pick the right invocation.

Run already in flight. Key facts:
- PR#26 @ 73ff016, MERGEABLE. Run **27928845104** IN_PROGRESS (test jobs running, traceability already SUCCESS).
- CI triggers = `pull_request` + `push:[main,dev-freeform]`. No `workflow_dispatch` → can't `gh workflow run` a branch; reruns only.
- `concurrency: cancel-in-progress: true` grouped by ref → **same-ref runs auto-serialize** (a new trigger kills the in-flight). Enforces operator's "no concurrent" constraint for free.
- Prior failures (02:37 etc.) are pre-fix (bed1878).

Confirm the in-flight run is on the fix commit before counting it as run-1.

⚠ Contradiction: watch exited 0 but **attempt 2 = FAILURE**. My watch attached to the stale attempt-1 completed-success state (8s sleep too short — rerun hadn't re-queued). Attempt 2 actually FAILED. And I already fired rerun #3 reflexively — need to diagnose attempt-2 failure FIRST before trusting anything.

**Source=`channel`, NOT `WATCHDOG-DEFAULT`. Recv at 2.0s, not 30s/120s.** The attacher itself reported `(false,false)` in ~2s — it did NOT hit the watchdog. todlando's pin (subscribed=false = the 30s watchdog defaulting on a late request_attach ack) is **refuted** by the very source-attribution label we insisted on keeping. The widened watchdog is **orthogonal** to this failure. The `2.0163s` reeks of a 2s deadline the attacher hit and returned false fast.

Found it. The attacher's **first** op:

```rust
let mut operator = match Brain::cold_start_pump(&attach_name, 1, Duration::from_secs(2)) {
    Ok(b) => b,
    Err(_) => { let _ = result_tx.send((false, false)); return; }   // NO fallback
};
```

`recv_t0` is set *after* spawning the attacher; the attacher's very first call is `cold_start_pump(.., 2s)`. **2.0163s = that 2s connect deadline timing out**, then `send((false,false))` via channel. The 30s/120s watchdog is never reached.

**todlando's pin was a code misread.** His commit says *"the 2s pump deadline hypothesis did not apply (attacher uses plain cold_start)."* False — the pump-mode attacher uses `cold_start_pump` **with a 2s deadline**; only the *fallback* is plain cold_start (and the attacher has no fallback — it bails to `(false,false)`). The real elastic bound under Windows starvation is the attacher's **operator-IPC connect handshake**, not `request_attach`'s ack. Local repro never starved that 2s connect, so it never surfaced.

The watchdog knob we shipped is correct hygiene but **orthogonal** — wrong bound. Confirm whether a_journaled shares the same 2s connect.

Both gates share it: a_journaled attacher (`:633`→`:636`) and p0_paste attacher (`:1932`→`:1935`) — each does `cold_start_pump(.., 2s)` with **no fallback**, bailing to `(false,false)`. Same latent failure; a_journaled just didn't trip this run.

**Corrected root cause (proven, CI log + code):**
- The attacher's operator-IPC connect (`cold_start_pump`, 2s deadline) timed out under Windows shared-runner load → `(false,false)` via channel at 2.016s → `subscribed=false` → assert `:2095` fails.
- The 30s/120s `result_rx` watchdog is **never reached** — proven by `source=channel`, the exact label we forced todlando to keep. The shipped watchdog knob is correct hygiene but **orthogonal** to this flake.
- todlando's pin rests on a code misread (*"attacher uses plain cold_start"* — it uses `cold_start_pump` **with** a 2s deadline).

**Critical correction to the starvation story:** attempt 2 was a **serialized rerun** — zero concurrent matrices from me on this ref (cancel-in-progress guarantees it). It starved anyway. So the trigger isn't *my* matrix stacking; the 2s connect is simply too tight for the shared self-hosted Windows box under *any* co-tenant load (live agents share hfenduleam). → An operational "don't stack runs" fix is **insufficient**; a code fix is required.

Publish stays **HELD**. todlando is parked awaiting my x3-green ping — holding him until you pick the fix shape, so he cuts once.


AskUserQuestion

Question: x3 is RED (attempt 2 reproduced the flake; real bound = the attacher's 2s cold_start_pump connect under shared-runner load, not the watchdog). Which fix shape do I gate + dispatch to todlando?

Choices:
SPT_ATTACH_CONNECT_DEADLINE_MS, default 2000ms (local tight), CI exports ~30000. Applied to both attacher connects (:633 + :1932) via one shared helper. Mirrors the watchdog knob exactly. Minimal, matched-to-mechanism, ship-ready. A real connect-wedge still bails false → assert still catches it.
fn attach_connect_deadline() -> Duration {
  env SPT_ATTACH_CONNECT_DEADLINE_MS
    .parse().map(from_millis)
    .unwrap_or(from_secs(2))   // default tight
}
// :633  cold_start_pump(.., attach_connect_deadline())
// :1932 cold_start_pump(.., attach_connect_deadline())
// CI env: SPT_ATTACH_CONNECT_DEADLINE_MS=30000
One multiplier env (e.g. SPT_TEST_TIMING_SCALE) applied to ALL test-rig cold_start_pump/deadline bounds (the ~8 from_secs(2) sites: drivers, viewers, helpers, attachers). Kills the whack-a-mole — any starved bound scales together. Broader change, more surface to review pre-publish.
fn rig_dur(base: Duration) -> Duration {
  base * env(SPT_TEST_TIMING_SCALE).unwrap_or(1)
}
// every from_secs(2) -> rig_dur(from_secs(2))
// CI env: SPT_TEST_TIMING_SCALE=15
// (covers connect, watchdog, slice bounds)
Attacher retries cold_start_pump on timeout (bounded loop, e.g. 3x2s) instead of bailing to (false,false). Tolerates a transient starved connect without widening the deadline. More code than a knob; keeps the 2s default per-attempt.
for _ in 0..3 {
  if let Ok(b) = cold_start_pump(.., 2s) { op = b; break }
}
// no env knob; 3 attempts x 2s = 6s worst
// real wedge: all 3 fail -> bail false -> assert catches

Operator: best judgment. **Ruling: option 1 (connect-deadline knob)** — minimal, matched, ship-ready, mirrors the watchdog knob. But scoped to cover the **class**, not just the one observed site, so we don't reopen a third time: the same starvation can blow the driver connect (`:574/:1875` → no FLOOD → got_output=false) and the wait_for_stream viewer (`:1516`). One knob, applied to every result-gating `cold_start_pump` connect in this file. Option 2 (rig-wide) held in reserve if a non-connect bound surfaces; option 3 (retry) is more code and 3×2s can still starve.

Plus a lesson fix: re-add a **cheap connect-timeout attribution print** — we dropped the per-step prints (condition 5) and had to reverse-engineer the 2.0s. Both attachers should say "operator connect TIMED OUT after {elapsed}" so the next one is self-evident.

Dispatching todlando the corrected pin + ruling + cut conditions.

$OWL send todlando <<'EOF'
x3 RED — gate REOPENED. Publish HELD. Your pin was a code misread; corrected root below, with the fix ruling.

WHAT HAPPENED: attempt 2 (Windows, SERIALIZED rerun — zero concurrent matrices from me, cancel-in-progress guarantees it) reproduced p0_paste:
  PASTE_FLAKE: MAIN recv -> (false,false) after 2.0163245s (source=channel)
  subscribed=false  panic :2095

CORRECTED ROOT (proven, CI log + 73ff016 code):
- source=channel (NOT WATCHDOG-DEFAULT) + 2.016s = the attacher's operator-IPC connect timed out. The attacher's FIRST op is `Brain::cold_start_pump(&attach_name, 1, Duration::from_secs(2))` (:1932) with NO fallback -> on the 2s deadline it `send((false,false)); return`. recv_t0 is set AFTER spawning the attacher, so 2.016s == that 2s connect deadline + ~16ms. The 30s/120s result_rx watchdog is NEVER reached.
- Your commit says "the 2s pump deadline did not apply (attacher uses plain cold_start)." That's the misread: the pump-mode attacher uses cold_start_PUMP WITH a 2s deadline; only the FALLBACK is plain cold_start, and the attacher has no fallback. Your local repro never starved the 2s connect (recv ~16ms) so this path never surfaced.
- The shipped watchdog knob is CORRECT HYGIENE and STAYS (the source-attribution label we kept is exactly what caught this) — but it is ORTHOGONAL to this flake.
- Starvation story corrected: it failed SERIALIZED, so it's not my matrix stacking — the 2s connect is simply too tight for the shared self-hosted Windows box under ANY co-tenant load (live agents share hfenduleam). An operational "don't stack" fix is INSUFFICIENT.

FIX RULING (option 1 — connect-deadline knob, scoped to the CLASS so we don't reopen a 3rd time):
1. New shared helper attach_connect_deadline() reads SPT_ATTACH_CONNECT_DEADLINE_MS, DEFAULT from_secs(2). One helper, no copies.
2. Apply it to EVERY result-gating cold_start_pump CONNECT deadline in inject_control_wedge.rs: both attachers (:633 + :1932), both drivers (:574 + :1875), the wait_for_stream viewer (:1516), and the keystroke op (:1912). NOT the read_event_until 250ms slices (those aren't connect bounds — leave them).
3. DEFAULT stays 2s — local tight; a real connect-wedge still waits 2s, bails false, assert still catches it.
4. KEEP the watchdog knob + source-attribution exactly as-is (orthogonal but correct).
5. LESSON FIX: re-add a CHEAP one-line attribution on the attacher connect-Err path (both attachers), before the send((false,false)): eprintln the elapsed, e.g. "PASTE_FLAKE/JRNL_FLAKE: operator connect TIMED OUT after {t0.elapsed():?}". We dropped the per-step prints and had to reverse-engineer from 2.0s — don't make the next triage do that.
6. CI exports SPT_ATTACH_CONNECT_DEADLINE_MS=30000 job-level beside SPT_ATTACH_GATE_WATCHDOG_MS in ci.yml matrix job.
7. Non-vacuous unchanged: still asserts subscribed && got_output. Verify locally: SPT_ATTACH_CONNECT_DEADLINE_MS=1 -> gate fails fast WITH the connect-timeout print (proves wiring + real-wedge still caught); default 2s -> pass. clippy -p spt-daemon --all-targets -D warnings clean.

Cut in the delivery-control worktree (don't touch the operator's main worktree — it's on main @ c84daff). Ping when pushed; I gate-read the diff, then I drive x3 serialized (properly this time). Go.

Dispatch corrected pin + connect-deadline fix ruling to todlando


➜ SENT:todlando


Dispatched to todlando: corrected pin + option-1 ruling (connect-deadline knob, scoped to the class) + 7 cut conditions + the lesson fix (cheap connect-timeout print).

**State now:**
- Publish HELD. Gate reopened. Run 27928845104 cancelled.
- todlando cuts in delivery-control worktree → pushes → fresh CI fires (new clean attempt 1).
- Then: I gate-read the diff → drive x3 serialized **properly** (the bug this round: my post-`rerun` watch attached to the stale completed attempt and false-greened #2; next time I poll until the attempt flips + verify per-attempt conclusion, not just watch exit code).

todlando caught my misread and **proved it empirically** (`SPT_ATTACH_CONNECT_DEADLINE_MS=1` → fails fast but the connect-Err print never fired → the connect didn't Err; `request_attach`'s bounded ack read did). He's right:

- `cold_start_pump`'s `Duration` = **io_timeout** (per-IPC-call READ deadline, brain.rs:311-323); the socket connect (brain.rs:312) is **unbounded**. So cold_start_pump never times out at 2s.
- The real bite at 2.016s: `request_attach` → `net_open_stream` reads the `NetStreamOpened` ack in a loop bounded by `call_deadline = now + io_timeout` (2s). Under co-tenant load the journaled ack outruns 2s → read TimedOut → net_open_stream Err → request_attach Err → **request_attach** match arm sends `(false,false)`. Bitten 2s early by the per-call deadline, before the 30s watchdog.

So todlando's *original* "sole elastic bound = net_open_stream ack" was right; his only error was attributing the false to the 30s watchdog. **My** correction (connect timed out / no fallback) was wrong too — converged now. Fix is the same (env-tune that Duration), but the attribution (knob name + print path) was wrong. His proposed A (rename → `SPT_ATTACH_IPC_DEADLINE_MS`/`attach_ipc_deadline()`) and B (move the print to the request_attach Err arm) are correct. Accepting both.


$OWL send todlando <<'EOF'
ACCEPTED — A + B both. Good catch; you prevented misread #3, and the empirical proof (DEADLINE_MS=1 fails but the cold_start_pump connect-Err print never fires) is exactly the right way to settle it. That's the executor behavior I want — refuse to ship a wrong attribution even when the fix is right.

Converged mechanism (correct, final): the Duration passed to cold_start_pump is io_timeout = the per-IPC-call READ deadline (brain.rs:311-323, call_deadline=now+io_timeout); the socket connect is unbounded. request_attach -> net_open_stream reads the journaled NetStreamOpened ack bounded by call_deadline; under co-tenant starvation that ack outruns the 2s io_timeout -> net_open_stream Err -> request_attach Err -> the attacher's request_attach match arm sends (false,false) at ~2.0s via channel, 2s BEFORE the 30s watchdog. net_stream_subscribe is fire-and-forget (no ack read) — never the false. Your original "sole elastic bound = net_open_stream ack" was right all along; the only wrong part was pinning the false to the 30s watchdog. My connect-timeout correction was wrong too. Now correct.

RULING (final cut):
1. A: rename knob SPT_ATTACH_CONNECT_DEADLINE_MS -> SPT_ATTACH_IPC_DEADLINE_MS; helper -> attach_ipc_deadline(). Doc it as the pump per-IPC-call read deadline (io_timeout), NOT a connect.
2. B: attribution print on the request_attach Err arm (both gates): "PASTE_FLAKE/JRNL_FLAKE: request_attach net_open_stream ack TIMED OUT after {elapsed} (io_timeout bound, source=channel)". Drop the cold_start_pump-arm print (never fires for this flake).
3. Default stays 2s; CI exports SPT_ATTACH_IPC_DEADLINE_MS=30000 job-level. Real wedge -> ack never lands -> Err at io_timeout -> false -> assert still catches (and total < the 120s watchdog).
4. KEEP the watchdog knob as the outer ceiling (harmless + correct; catches a true forever-wedge as a clean fail). Two distinct bounds, two knobs.
5. Non-vacuous unchanged. clippy clean. Re-verify: DEADLINE_MS=1 -> both gates fail fast WITH the new request_attach-ack print; default 2s -> pass.

The truncated tail of your msg ("Also FYI: 3 W2 helper connects (outpu...") cut off — resend it. Ruling in advance: any helper whose connect/ack gates a RESULT (output_contains_within :912, deliver helpers :951/:1081, wait_for_stream viewer :1516) should use the SAME attach_ipc_deadline() knob; leave non-result-gating ones at the 2s literal. One knob only.

Push when correct. I gate-read the diff, then I drive x3 serialized.

Accept A+B attribution fix, final cut ruling


Final ruling sent: accept A (rename → `SPT_ATTACH_IPC_DEADLINE_MS`/`attach_ipc_deadline()`, doc as the io_timeout per-IPC-call read deadline) + B (attribution print on the request_attach Err arm). Keep watchdog knob as outer ceiling. Asked todlando to resend his truncated W2-helper tail; pre-ruled it (same single knob for result-gating helpers only).

**Mechanism converged** — the bound is the **per-IPC-call read deadline (io_timeout = the 2s Duration arg)** bounding `net_open_stream`'s ack read; not a connect, not the 30s watchdog. todlando's original "net_open_stream ack" pin was right; both our watchdog/connect attributions were wrong. Fix substance unchanged (env-tune that Duration); naming + print corrected.

todlando re-cuts → I gate-read → drive x3 serialized. Standing by.

5. Asserts untouched (non-vacuous); clippy + traceable exit 0. ✓

All conditions verified in-diff: attach_ipc_deadline() default 2s (Err+parse-fail), doc'd as io_timeout NOT connect w/ brain.rs cites; wired to all 9 result-gating cold_start_pump sites, no 2s literal left; attribution print on the request_attach Err arm (both gates) with the io_timeout/source=channel wording, connect-arm print gone; CI SPT_ATTACH_IPC_DEADLINE_MS=30000 beside the kept watchdog knob; asserts untouched (non-vacuous); clippy + traceable clean. Zero product diff. The =1 race caveat is fine (wiring proof; 2s kills it). Approved. Driving x3 serialized now — properly (verifying per-attempt conclusion this time, not watch-exit alone). Ping you on x3-green.

x3 **CLEAN** — all three green on 45cc479, each verified per-attempt:
- **#1** attempt 1 → success
- **#2** attempt 2 → success
- **#3** attempt 3 → success

Serialized (cancel-in-progress + one-at-a-time), no concurrent stacking. Gate satisfied.

Pinging todlando + presenting to operator for publish-confirm.


$OWL send todlando <<'EOF'
x3 CLEAN — GATE PASS. All three runs GREEN on 45cc479 (run 27930772962, serialized via cancel-in-progress, each verified per-ATTEMPT conclusion not watch-exit): attempt1=success, attempt2=success, attempt3=success. Both Windows + Linux legs + n1-gates + traceability green every pass. The io_timeout-deadline fix holds under the shared-box load that tripped attempt-2 last round.

My gate is GREEN. Presenting to operator for publish-confirm now. On operator GO -> deployah cuts v0.13.0 (merge PR#26 + version bump + CHANGELOG-as-release-body + Cargo.lock first-party bump + sign+publish). I'll relay the GO. b4 sync stays deferred (cosmetic, post-publish via throwaway worktree). Solid work on refusing the two misreads — the fix landed correct because of it.

Ping todlando: x3 clean, gate pass


➜ SENT:todlando


x3 clean, gate GREEN — sent todlando.

**v0.13.0 publish-gate: SATISFIED.** Summary of the saga:
- Windows `p0_paste`/`a_journaled` flake root-caused (with todlando catching two attribution misreads — mine and his own): the bound is the **per-IPC-call read deadline** (`io_timeout`, the 2s `Duration` arg to `cold_start_pump`) bounding `request_attach`'s `net_open_stream` ack read. Co-tenant starvation on the shared self-hosted Windows box pushes that *serviced* ack past 2s → Err → `(false,false)` at ~2.0s, 2s before the 30s watchdog.
- Fix @ 45cc479: env-tunable `SPT_ATTACH_IPC_DEADLINE_MS` (default 2s tight / CI 30000), 9 result-gating sites, correct attribution print, watchdog knob kept as outer ceiling. Test+CI only, zero product diff.
- x3 serialized: 3/3 green, verified per-attempt.

**Remaining to publish v0.13.0 (operator GO required):**
1. **Pre-publish CHANGELOG vet** — confirm it covers every user-facing surface in `v0.12.x..v0.13.0` and no bullet overstates scope (my prior burn: v0.8.0 shipped with a miscite). Recommend doing this before tag.
2. Merge PR#26 → version bump (workspace + Cargo.lock first-party) → CHANGELOG = release body → deployah sign+publish (counter 26, MINOR).

Your call: **relay GO to deployah now**, or hold while you/I vet the CHANGELOG first? I recommend the CHANGELOG vet, then GO.


proceed. once published, inform perri


Proceeding: CHANGELOG vet → GO to deployah → inform perri on publish. First, vet — read the CHANGELOG + version state on 45cc479 and the commit range since the last tag.
