ci/woodpecker/pr/ci Pipeline failed
fix(#1262): adoption follow-ups - enumeration exclusion, SEND-honoring verdict suite, retire rc=2-is-normal guide text
- 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.

# test-send-message-verdict.sh — locks the fail-loud verdict logic of the patched
# send-message.sh against three real tmux-pane fixtures on a throwaway socket:
#
# 1. DELIVERED — a REPL that renders a ` ` input box and submits on Enter
# (text scrolls to history, box clears) => exit 0 "✓ delivered".
# 2. DELIVERED — a pane with NO prompt glyph that DOES submit => exit 0. A pi
# seat is this fixture (U+2500 rule, no glyph). Reshaped for
# #1257; see the note at the fixture for why the old exit-2
# assertion was wrong.
# 2b. UNCONFIRMED— a glyphless pane that never submits (raw/no-echo hung TUI)
# => must fail loud. This carries the historical
# false-positive guard that fixture 2 used to be credited with.
# 3. DRAFT — a ` `-prompt pane that never submits (message stays on the
# input line) => exit 2, stderr "unsubmitted draft".

# and locking it in is what kept E7 alive: the pane submits, so "delivered" is
# the truth, and a pi seat — whose input box is a bare U+2500 rule with no glyph
# — IS this fixture. Reporting exit 2 for it told operators a delivered message
# may be undelivered, and the retry that advice invites is the duplicate.

# The guard this fixture was reaching for is real and is NOT dropped: "never
# infer delivered from absence" is now enforced positively by fixture 2b below
# (glyphless AND not submitting => must fail) and by fixture 3 (locatable box
# still carrying our tail => draft). Absence alone decides nothing either way.
