Owner ruling 2026-10-07: "I thought we weren't appending transmit
messages to the trace store anymore ... They should only come in from
echo." The one exception the echo-row change kept — a Tx ✗ row
appended when an enqueue was refused, "because there the queue did say
no" — is withdrawn. A refused send was still an intent written into
the store every consumer reads (decode, plots, per-message counts,
fps.tx, bus load, logger, Save Capture), so the store now takes no row
from any transmit intent, accepted or refused.

Removed:

• append_refused_tx_row, UndeliveredTx, MAX_UNDELIVERED_RUNS, the
  AppState::undelivered_tx field and its clear-with-the-capture.
• The paged trace record's tx_delivery field (host ipc.rs and the
  frontend types.ts), the trace's Tx ✗ label, its row class,
  tooltip and CSS.
• The tests that pinned the old row and the marks' run-length bound.

What a refusal is now: the manual send's wire status to its caller
(not_connected / failed); a periodic with no room as a missed
period, and one whose route is down parks (ADR 0039); a batch a session
has gone away under is dropped and the next tick parks it; the peer's
own refusals stay the bus-health per-bus refusal count (ADR 0060).

The rule is written down where reviewers read it: ADR 0061 (a row is
the wire's account; an enqueue or send return is an intent and yields
no row, count or sample; a Tx row is an echo; the PEAK caveat — its
echo means "on the wire", not "acknowledged", so an error-passive
transmitter's echoes are withheld and the controller's TEC is the
wire's account of a failed transmission; backends without
receive_own_messages show no Tx rows), a CONTEXT.md entry, and a
paragraph in CLAUDE.md. ADR 0039 and ADR 0023 carry dated amendments
for the withdrawn row; README's transmit section is corrected.

Tests: a send no session carries, a send onto a gone adapter, a
periodic batch the session refuses (new, through fire_due) and an
accepted send each leave no row, no per-message count and no tx rate.

Verified: cargo test -p cannet-gui (1437 passed), clippy -p cannet-gui
--all-targets -D warnings, cargo fmt --check, rustdoc -D warnings for
cannet-gui, pnpm test (3765 passed), pnpm build.
