Multi-line task bodies arrived in Claude Code as "[Pasted text #N +M lines]"
and sat in the input buffer forever — the trailing Enter that SendKeys
appends to the paste is consumed as a newline inside the paste, not as a
submit. Observed live on ccl-auto-11 (secumon) and ccl-auto-12 (secuops):
prompt visible, agent idle.
- tmux.Client grows a SendEnter(session) method. ExecClient runs
`tmux send-keys -t <sess> Enter` (no preceding text), which Claude's
TUI accepts as the explicit submit action after a paste.
- Dispatcher: after SendKeys(msg), sleep 500ms for the paste to register,
then SendEnter. Same sequence a human would perform.
- Five mockTmux implementations updated (quota, dispatcher, switcher,
lifecycle, watcher tests).

Production had two disjoint tmux pools named alike but for different
purposes:
ccl-0..ccl-9 — manual/interactive sessions (operator)
ccl-auto-11..ccl-auto-20 — autonomous dispatcher pool
Until now the daemon's loops iterated prefix + 0..Max, so with the
deployed config ("prefix: ccl-auto", min=2, max=10) the dispatcher
looked for sessions "ccl-auto0..ccl-auto9" that never existed, while
the real auto pool ccl-auto-11..20 was invisible. Net effect: no task
was ever dispatched, and killAllPoolSessions fabricated phantom
"ccl-auto0/1" sessions on each swap.
- AutonomousConfig gains StartIndex (yaml start_index, default 0).
Behaviour is unchanged when StartIndex is 0.
- Monitor, switcher (kill + recreate), dispatcher (findFreeSession),
and lifecycle (EnsureAll + reconcile) all iterate
[StartIndex, StartIndex+Max) so the daemon only touches its own
range and leaves ccl-0..ccl-9 alone.
- Production config updated to prefix: "ccl-auto-", start_index: 11,
min: 10, max: 10 — covering the 10 real ccl-auto-11..20 sessions.

v0.2.2's 2-poll confirmation was insufficient because Anthropic 500/503
errors are printed into Claude Code's conversation transcript and stay
visible in every tmux capture until the user scrolls. A persistent
server error would confirm on the second poll and still trigger a swap.
Root cause: the pattern "rate limit" (bare substring) matched any 500
payload that happened to mention rate limits in its error text. Real
HTTP 429s from Anthropic are typed as "rate_limit_error" in the error
payload — and that's the signature we should actually key on.
- Remove "rate limit" from quotaPatterns (too generic — matches transcripts).
- Add "rate_limit_error" (Anthropic's typed 429 error) and "5-hour limit".
- Add serverErrorPatterns veto: "api_error", "overloaded_error",
"internal server error", "api error: 5". When any is present in the
pane, isQuotaExhausted returns false even if a quota pattern matched.
- 4 new subtests covering the veto paths + sanity that real 429s pass.

Anthropic HTTP 500 errors surface in the TUI with payloads containing
"rate limit" text, which the monitor was matching against quotaPatterns
and treating as a real 429 quota hit. With no cooldown and no
confirmation, a burst of 500s produced sub-minute ping-pong swaps that
tore down user sessions.
Two-layer fix:
- quota.reactivate_cooldown (already in config, 5m) now gates the
monitor too — not just the dispatcher. A completed swap suppresses
further detection for the cooldown window.
- A hit with no parseable reset time is treated as suspected only on
the first poll; a second consecutive poll is required before
emitting SwapRequested. Legitimate 429s with "resets in ..." still
swap instantly on the first detection.
Adds state.RecordSwap / LastSwapInfo for the cooldown, and a
forensic log line on every detection: trigger_session, matched
pattern, 120-char pane snippet.
Tests cover: instant swap with reset, 2-poll confirmation without
reset, and suspected-state reset on recovery.
