Test quality: assert TikTok error shown, behavioral SSE/trim tests, explicit no-raise (A9-1, A9-2, A9-6)

Message pipeline lows: captioned album main, passive files, reply history, off-loop read, trigger helper, cancel cleanup, empty retry, split throttle, edit-death fallback (A4-06..A4-13, A4-16)

Bound streaming entry wait by route attempt timeout (A4-01)

Subagent re-review: fix confirmed misses, harden thin tests

Independent re-review: fix missed regressions and close gaps

Fix regressions found by adversarial review: routing, rendering, rate limits

Cleanup wave 6: one shared SSE parser and one shared fallback chain, drop dead code and a silent list alias, cover the previously untested failure branches

Fix chat-lock hangs: TTS async with timeout, stream handshake capped, route attempts bounded by remaining budget, one shared chat-lock limit

Luna audit fixes: album lock, multilingual routing, streaming budget, quota and persistence hardening

Streaming pacing: reveal from first piece, follow measured arrival rate

Groq provider: qwen head + gpt-oss reserve on light routes (calibrated 21.09.2026), streaming, quota/stats/diag, 8 tests

Comment polish: Russian pro-style comments, keep dated evidence short (+426/-2765). Fix: bot.send_chat_action -> bot.bot.send_chat_action (was AttributeError, typing indicator never showed)
