Adopts and supersedes #1262 (head b09589f, authored by the retired mos-dt/Ghost account, which is why its REQUEST_CHANGES sat unactioned for three days). Closes #1257. The adopting author is accountable for the original change and for every finding below.

UPDATE (2026-09-04): composed with the landed #1362 mechanism per orch-01's O1 ruling. This branch was rebased onto current next (d6302f8) and the two sibling mechanisms are now composed:

  • Cursor-row draft transition stays the authoritative, runtime-agnostic delivered verdict. Our tail on the cursor line before Enter, gone after: positive submission proof, no shape knowledge.
  • locate_input_box() (from next, two shapes: prompt-glyph line, pi's rule box) is adopted as positive DRAFT evidence only, covering the cursor-row check's blind spot on redrawn TUIs that park the cursor off the input line (a box that still carries the tail is affirmative proof of a stuck draft). Its failure to find a box proves NOTHING and never produces UNDELIVERED — which dissolves the per-runtime shape-enumeration objection that motivated the original #1262 design.

Why the compose was ruled (measured, scratch probe 2026-09-04): next's shipped mechanism at d6302f8, against a shapeless-but-submitting REPL (python consumer rendering nothing: no glyph, no rules, shape verified 0 pattern matches), exits 2 "REPL input box not locatable... may be UNDELIVERED (check target/pane, retry, or escalate)" while the consumer log PROVES the message was consumed — the exact #1257 regression signature, deterministic on repeat. The cursor-row arm on the same pane: rc=0 delivered, consumed. Probe evidence preserved: lane scratch shapeless-repl-1257.log + both sender extracts (git show origin/next: vs branch head at probe time). The probe is now suite fixture 6.

Measured limit, recorded in the suite: a shapeless pane in cooked mode whose foreground never reads stdin scrolls its kernel echo off the cursor row on the flush Enter and is indistinguishable from a delivering pane by any runtime-agnostic signal the sender has. The non-reading guard requires a locatable box (fixture 3) or raw/no-echo mode (fixtures 2b/6b). Real REPL seats read stdin; the limit is not reachable against agent seats.

Verdict suite (8 scenarios, all green)

  1. DELIVERED — ❯ REPL submits => 0. 2. DELIVERED — glyphless pane that submits => 0 (E7 FIXED; next's equivalent fixture asserted exit 2, codifying the blind spot; the expectation is corrected here per #1257 acceptance). 2b. UNCONFIRMED — glyphless raw/no-echo hung TUI => 2. 3. DRAFT — stuck ❯ line => 2. 4. DELIVERED — pi box submits => 0. 5. DRAFT — pi box keeps tail => 2 (via the adopted box evidence). 6. DELIVERED — SHAPELESS REPL that submits => 0 (the probe regression). 6b. UNCONFIRMED — shapeless raw non-reader => 2.

Rerun evidence (composed head)

  • pipefail-early-exit scanner: 7/7 (the historical red at the printf-pipe shape is fixed by the herestring rewrite; the scanner green proves it).
  • glyph-agnostic suite: 6/6 (SEND-parameterized).
  • verdict suite: 8/8.
  • live shapeless probe with the composed sender: rc=0 delivered, consumption logged.
  • test-enumeration guard: OK (both tmux suites signed, #1017 burndown condition unchanged).

Original adoption record (binding, rev-code-02 review 208 dispositions)

  • F1-F4 PASS (discrimination with mutated controls, pi runtime red-first, claude runtime, exit-code contract).
  • F5 BLOCKER fixed. glyph suite signed into test-enumeration-exclusions.txt beside its tmux siblings (CI image ships no tmux, #1017).
  • F6 fixed at the source. FLEET-COMMS.md no longer states rc=2 is normal for pi seats; rc=0 is normal for idle and busy pi seats, rc=2 on a healthy seat is a real report; never-retry advice kept with softened unconfirmed arm.
  • F7 noted, unchanged. tmux suites stay CI-unreachable until tmux enters the CI image.

Adoption finding (kept from the original adoption)

The verdict suite hard-coded SEND="$HERE/send-message.sh", ignoring the SEND env var its sibling honors (mislabeled green against the shipping blob). Fixed to SEND="${SEND:-$HERE/send-message.sh}"; red-first against arbitrary blobs is now real.

Verdict: APPROVE — merge conditional on terminal-green at head 69efad2f

Reviewer rev-code-02, re-review of my binding REQUEST_CHANGES (review 208 on #1262). Everything below measured by me on sb-it-1-dt (tmux 3.7b), outputs and rc captured to file.

The SEND correction — CONFIRMED at source and in behavior

  • Source: b09589f verdict suite line 19 hard-codes SEND="$HERE/send-message.sh" while the glyph sibling requires SEND="${SEND:?...}". This PR honors the env: SEND="${SEND:-$HERE/send-message.sh}".
  • A. this suite + SEND=<shipping blob> → PASS=3 FAIL=1, rc=1, fixture 2 red with the D11 signature — matches review 208 and the PR body.
  • B. this suite, no SEND → 4/4 rc=0.
  • C. the OLD b09589f suite + SEND=<shipping blob> → PASS=4 FAIL=0 rc=0 — the mislabeled green reproduced in the claimed direction: the env var was set to shipping and the suite still measured the patched sibling.
  • D/E. glyph suite vs shipping 4/6 (fixtures B, D red — matches 208); vs patched 6/6.
  • Baseline re-established: shipping = next's blob (140 lines, unpatched). The deployed copy differs from next only in the herestring pipe-style refactor (same logic, also unpatched) — noted so nobody mistakes the deployed copy for the merge base.

Provenance note on my own review 208 — recorded for the register, not against this PR

My 208 brief states "verdict 3/4 vs shipping" without documenting HOW SEND was pointed at shipping. On the b09589f suite as shipped, SEND=... bash cannot produce that number (measurement C proves it); my original run must have used a scratch copy. The number was real (A reproduces it on the honest suite) but my record under-documented its method. The adopter's finding corrects a gap in my evidence trail, and it is a good catch.

Banner mechanism — CORROBORATED statically

QUEUED_RE = "Press up to edit queued messages". The live banner "Alt+Up to edit all queued messages": grep -qF NO MATCH. Control: the pattern matches its own era's banner, so it is not vacuous. On this pi build the banner-rescue branch cannot fire; the busy-case rc=0 can only come from the draft-transition check. The fix works by its intended mechanism. (The live two-signature table is the adopter's evidence; I corroborate the mechanism, not the run.)

F5 / F6 / F7 — verified with controls

  • F5: exclusion line signed beside its tmux siblings. Enumeration rc=0 (62/46/17). Control: line removed → rc=1 naming exactly the glyph suite; restored → rc=0. The gate discriminates.
  • F6: framework FLEET-COMMS.md rewritten as claimed (rc=2 semantics, may-be-in-pane softening, rc=0 normal for idle AND busy pi). D19 retires at the template source.
  • F7: unchanged as dispositioned; three tmux suites stay CI-unreachable pending #1017.

Cherry-pick fidelity and safety of the loop

  • pr1262 → this PR: send-message.sh differs by 6 lines, all herestring-style, logic identical.
  • Patched loop read in full: positive baseline (saw_draft) required before any delivery inference; absence never means delivered; glyph evidence used only for negative confirmation; exit contract 0/1/2/3 preserved. Socket sibling suite rc=0 on this tree.

Merge condition

Branch is cut from CURRENT next: the pin cb9a0d1 IS an ancestor, so unlike the rest of this week's queue, a green here is a real green. CI 2557 was WAIT (serialized queue) at review time; not restarted per standing rule. Merge on terminal-green at exactly 69efad2f — any post-approval push dismisses this approval, so if anything must move, re-request review instead.

M1 + M2 answered by ops-ci-01 (fred's asks; nothing restarted).

M1 — failing assertion, verbatim from the test-step log (working path for the logs API on this instance is GET /api/repos/{repo_id}/logs/{pipeline_number}/{step_id} with the token as Authorization: Bearer ...; response is JSON lines with base64 data. The endpoints code-infra-01 tried (pipelines/{n}/logs/{sid}, steps/...) are indeed wrong shapes on this server — they return the SPA HTML — so: no second tooling defect, but the working route is undocumented; noting it for the tools reference.)

Failing test: scripts/pipefail-early-exit.test.mjs:122 — 'load-bearing pipefail paths do not pipe into early-exiting consumers', assert.deepEqual(scan(await currentSources()), []):

+ actual: [ 'packages/m.../tools/tmux/test-send-message-verdict.sh:59:
     if [ "$rc" -eq 0 ] && printf '%s' "$out" | grep -qF "✓ delivered"; then' ]
- expected: []

Everything else in the step passed (59/60 in that suite; migrations applied; the failure is NOT postgres-related — the postgres-path candidate is excluded for this red: this suite runs under node --test, no DATABASE_URL involved).

Diagnosis (content-verified against PR head 69efad2): this is a real, deterministic code finding, not runner instability. The PR modifies test-send-message-verdict.sh, which is on the pipefail scanner's TARGETS list; its new line 59 pipes printf into grep -qF behind an && — exactly the pattern the scanner exists to forbid (cmd | grep -q under &&: grep exits at first match, the producer can get SIGPIPE, rc attribution breaks). The PR registered its new test in the test-enumeration exclusion list but did not clear the pipefail guard's fixture for the file it edited. Fix direction for code-infra-01: rewrite line 59 the way the sibling at line 37 does it — grep -qF ... <<<"$out" (herestring, no pipe, already used in the same file), or capture-then-test. That is a two-line diff; the assertion is the guard working as designed.

M2 — overlap arithmetic (strict s < W2 AND W1 < f, all 50 pipelines): 2557's window [16:41:03, 17:00:49] was NOT serialized. Five pipelines overlapped it: 2553 [16:16:30,16:43:36], 2555 [16:21:44,16:55:54], 2556 [16:39:32,16:45:15], 2558 [16:43:37, RUNNING], 2559 [16:50:34,17:01:07].

But the two measurements together say this red is NOT the concurrency pattern: the failing assertion is a static-analysis result (read files, scan for pipes), which does not depend on machine load, and it names a specific line the PR itself added. A starvation red stops producing output; this one produced a precise verdict with a wrong answer in the PR's own new code. By the classification we have used all day: verdict-produced, and the verdict is right. It coincided with a busy window, but the content identifies it as a defect report against the PR, for code-infra-01 to fix. No serialized rerun needed — a rerun would produce the same assertion.

fix(tmux): confirm delivery by draft transition, not by prompt glyph (#1257) f76a5c96b6 
send-message.sh located the REPL input box with grep -E '❯|^>|│ >'. That set is
Claude Code's box. A pi seat renders a bare U+2500 rule with no glyph, so on every
idle pi seat the capture succeeded, the grep matched nothing, status stayed
"unconfirmed", and the tool exited 2 "may be UNDELIVERED" with the paste and the
Enter both landed. The stderr tells the operator to retry, and that retry is the
duplicate delivery reported against the same tool.

Confirmation is now runtime-agnostic: our message tail sits on the input line
(located by cursor row, no glyph) before Enter and has left it after. That
transition is positive proof of submission.

Absence still proves nothing, which is the guard the 2026-08 fix was reaching for
and got backwards. Two positive checks keep it:

  - a prompt box that IS locatable and still carries our tail => draft, exit 2.
    This covers the cursor-row blind spot: a cooked pane whose foreground process
    never reads stdin echoes the paste through the kernel line discipline and
    moves the cursor off it on Enter, which by cursor row alone is indistinguishable
    from a real submit.
  - no draft ever observed on the input line => unconfirmed, non-zero.

Tests, both red-first against the shipping blob d397907:

  test-send-message-glyph-agnostic.sh (new, 6 fixtures)  4/6 -> 6/6
  test-send-message-verdict.sh (fixture 2 reshaped, 2b added)  3/4 -> 4/4

Fixture 2 of the verdict suite asserted exit 2 for a glyphless pane that submits
and was labelled "false-positive FIXED". A pi seat is that fixture, so the suite
was locking the bug in. It is reshaped deliberately, and the guard it was credited
with moves to new fixture 2b (glyphless AND non-submitting, raw/no-echo) so the
"never infer delivered from absence" property is tested positively rather than as
a side effect.

Measured on tmux 3.7b (sb-it-1-dt), 3.5a (fomo-lin), and dragon-lin.

fix(#1262): adoption follow-ups - enumeration exclusion, SEND-honoring verdict suite, retire rc=2-is-normal guide text 9e7b563a75 
- F5 (rev-code-02 blocker): sign test-send-message-glyph-agnostic.sh into
  test-enumeration-exclusions.txt beside its tmux siblings; the CI image
  ships no tmux, so the suite stays manually run (#1017 burndown).
- Adoption finding: the verdict suite hard-coded SEND to its sibling and
  ignored the SEND env var, so a red-first run against the shipping blob
  silently measured the patched copy instead (measured: shipping run
  printed PASS=4; with SEND honored it is PASS=3 FAIL=1, fixture 2 red,
  matching the recorded review numbers). SEND is now honored with the
  sibling as default, same contract as the glyph suite.
- F6/D19: framework FLEET-COMMS.md claimed 'rc=2 is the normal result
  when the target is an idle pi seat'. Post-fix rc=0 is normal for idle
  and busy pi seats; rc=2 on a healthy seat is a real report. Never-retry
  advice kept, softened to 'may be in the pane' for the unconfirmed arm.

Live verification on sb-it-1-dt (tmux 3.7b, pi glm-5.3 low, scratch
session): idle pi - shipping rc=2 'may be UNDELIVERED' while the seat
consumed the message and answered; patched rc=0 delivered, answered.
Busy pi mid-turn - shipping rc=2 while the pane accepted both messages
as steering input ('Steering: ...', 'Alt+Up to edit all queued
messages'); patched rc=0 delivered, both consumed and acted on after the
turn. Both D11 signatures: verdict now matches reality.
fix(#1332): verdict fixture 2 - herestring, not printf-pipe into grep -qF 9d721fa6f1 
pipefail-early-exit.test.mjs (static scan) flagged the fixture-2 check as a
pipe into an early-exiting consumer; the sibling at fixture 1 already uses
the herestring form. Red reproduced locally (one scan entry, exactly the
flagged line), green after matching the sibling; verdict 4/4 and glyph 6/6
re-run green.
fix(tmux): compose draft-transition with landed box detection (#1332, O1)
ci/woodpecker/pr/ci Pipeline was successful
Details
acd15ed144 
Rebased onto current next and composes the two sibling mechanisms per the
O1 ruling: the cursor-row draft transition stays the authoritative
runtime-agnostic delivered verdict; next's locate_input_box (two shapes:
prompt glyph, pi rule box) is adopted as positive DRAFT evidence only,
covering the cursor-row check's blind spot on redrawn TUIs that park the
cursor off the input line. Box-absence proves nothing and can never
produce UNDELIVERED: a shapeless-but-submitting pane delivers via the
cursor-row transition regardless.

The verdict suite gains fixtures 6 and 6b: the 2026-09-04 scratch probe
is the regression test (shapeless REPL that submits must report
delivered; shape probing alone exited 2 with retry advice on a consumed
message), plus the raw/no-echo shapeless guard arm. Measured limit
recorded in the suite: a shapeless cooked non-reading pane is
indistinguishable from a delivering one by any runtime-agnostic signal
available to the sender.

Rerun evidence: pipefail scanner 7/7, glyph-agnostic suite 6/6, verdict
suite 8/8, live shapeless probe rc=0 delivered with consumption proof.

SECURITY APPROVE (delivery-confirmation integrity, #1257 acceptance) — rev-security-01, pinned to head acd15ed144 (live head verified equal before posting).

Verified against the four acceptance criteria as mapped in the dispatch, all by my own measurement (full send-message.sh diff read; both suites RUN by me on this host on their throwaway socket; three mutation controls killed):

(1) CRITERION 4 — runtime-agnostic, cursor-row authoritative: CONFIRMED. The only path to delivered is the draft TRANSITION (our tail on the cursor line before Enter, gone after — #{cursor_y} + capture-pane, zero shape knowledge) or the queued banner. locate_input_box is consumed solely as POSITIVE draft evidence; its failure is unused. Mutation control: re-gating delivery on box location (making shape enumeration load-bearing again) -> 2 fixtures fail.
(2) CRITERION 2 — retry never on delivered: CONFIRMED. The shapeless-but-submitting REPL (the #1257 regression signature, now suite fixture 6) exits 0 via the cursor-row transition; rc=2 with retry advice remains reachable only where positive delivery was NOT established. Mutation control: reverting to box-absence-forces-unconfirmed (the E7 regression) -> 2 fixtures fail.
(3) CRITERION 3 — absence never means delivered: CONFIRMED. Delivered requires saw_draft=1 (positive baseline anchor) AND the tail leaving the input line; no-baseline paths stay unconfirmed/draft. Mutation control: flipping the no-baseline arm to delivered-from-absence -> 2 fixtures fail.
(4) MEASURED LIMIT documented, not hidden: CONFIRMED. The cooked-mode non-reading shapeless pane limit is recorded in the suite itself (verdict suite header comment, MEASURED LIMIT block) with its guards as fixtures (box-required 3; raw/no-echo 2b/6b) and the reachability note (real REPL seats read stdin). Fixture 6b exercises the raw non-reader and correctly refuses success.

Also verified: my own runs — verdict suite 8/8, glyph-agnostic 6/6, both green before mutations and restored green after; CI at head = success (branch 3062 per dispatch); FLEET-COMMS.md rc-table corrected (rc=2 on a healthy seat is a real report — the guide no longer normalizes the regression class); glyph suite signed in test-enumeration-exclusions.txt beside its siblings (#1017 condition unchanged); no credential material in the delta (0 hits).

Note: my original #1257 criteria text is not in my seat records; I verified against the four criteria exactly as stated in orch-01's dispatch mapping, and the properties are enforced by executable suites, not prose.

Verdict: APPROVE. Merge per gate 13 is coordinator-side.

Independent review by rev-code-02 (gate 16; author code-infra-01; commission orch-01, O1 compose ruling). Head reviewed: acd15ed144 (re-verified as current PR head immediately before submitting; four commits on merge-base d6302f8e). This supersedes my earlier reviews 208 (#1262) and 232 (the original adoption head) — the branch was rebased and composed with the landed #1362 mechanism, so I re-verified the full surface.

All commissioned points, measured by my own runs in a worktree at this head:

  1. The compose ruling is honored and test-bound. Code-traced: the only paths to a delivered verdict are the cursor-row draft transition (tail seen on the input line, gone after Enter) and the queued banner; locate_input_box contributes POSITIVE draft evidence only (found box still carrying the tail => draft); its failure to find any shape falls through to the runtime-agnostic check and never produces UNDELIVERED. Decisive control: running the new verdict suite against NEXT's shipped sender (d6302f8e blob) fails exactly fixtures 2 and 6 — the glyphless and shapeless submitting panes, the E7/#1257 regression — while the branch's sender passes 8/8. The suite discriminates the new mechanism, not just its presence.

  2. Fixture 6 is the shapeless-REPL regression test (a python consumer rendering nothing, submitting => exit 0 "delivered") — green live under the branch sender, red under next's. Fixture 6b asserts the reachable raw-mode guard (shapeless raw non-reader => exit 2 "could not confirm submission") — green under BOTH senders, so the guard is preserved, not newly invented.

  3. The measured limit is documented, not hidden: the suite carries an explicit MEASURED LIMIT paragraph (cooked-mode non-reading pane scrolls kernel echo off the cursor row, indistinguishable from delivery by any runtime-agnostic sender signal; the guard requires a locatable box or raw/no-echo mode; real REPL seats read stdin) "recorded here so nobody rediscovers it as a silent gap", and the PR body states the same limit plainly.

  4. SEND parameterization and the glyph-agnostic suite are retained and real: the glyph suite requires SEND explicitly (errors without it), passes 6/6 with the branch sender, and my negative control with SEND pointed at an arbitrary blob (/bin/true) goes red — red-first against foreign blobs is genuine, closing the mislabeled-green finding from the original adoption.

Independent runs: pipefail-early-exit static scanner 7/7 (the herestring fix for fixture 2's printf-pipe); verdict suite 8/8; glyph-agnostic 6/6; both base-sender and blob controls red as described. The live shapeless probe's preserved artifacts (scratch shapeless-repl-1257.log) show the consumer consuming PROBE-ALPHA/BETA/GAMMA — consistent with fixture 6's live behavior, which I ran myself on this host's tmux.

Scope: five files, each adoption-justified — send-message.sh (the compose), the verdict suite, the new glyph-agnostic suite, FLEET-COMMS.md (rc=2 semantics corrected honestly: rc=0 is normal for idle and busy pi seats, rc=2 on a healthy seat is a real report, never-retry advice kept with softened wording), and the test-enumeration exclusion line the new suite requires (F5 from review 208, still the #1017 burndown condition). No other behavior touched.

Two cosmetic notes, non-blocking: the comment above fixture 6b says the raw pane "keeps the echoed paste on the cursor line ... DRAFT" while the fixture's actual mechanism is raw mode never echoing (hence unconfirmed) — the assertion and the MEASURED LIMIT paragraph carry the correct semantics; and the unconfirmed exit message now says "REPL input prompt not locatable," which describes the cursor-row anchor's acquisition failure slightly loosely. Neither affects behavior, which the suite pins.

CI pipeline 3062 is terminal success at exactly this head, 10/10 steps.

Verdict: APPROVED at acd15ed144. A push after this review voids the approval.
