Medium wave 4: validated env numbers, Upstash backend and shutdown flush tests, deno check/lint in CI, reproducible pip step, docs for missing variables

Reliability wave 3: router skips quota-exhausted models, prune never drops a chat holding the lock

Security wave 2: gate deploy on push+own repo, 401 and denial logging on admin endpoints, FastAPI schema off, proxy body cap, ownerless pick confined to chat, loud warning about secrets derived from BOT_TOKEN

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

Split glued 3-item bullet lists in both render paths (prod 26.09.2026 threshold miss)

Continue feature: resume interrupted stream answers on bare continue request

Reliability: cap malformed-call retry by route deadline, service quota separation, album buffer cleanup

Security: validate pick before pop (foreign tap no longer burns token), SSRF guard on download hosts

UX batch: start examples, pick reissue on expired tap, TTS multi-part, reset doc fix

Claude-parity fixes: callback filters for pick buttons, inline numbered-list splitter in both render paths, prompt ban on glued lists

Luna audit round 2: review fixes (regex bounds, mixed albums, redaction guards)

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

Merge media-fail-honest: honest media errors and media entry log

Fix sticker test lang expectation

Media drops are honest: fetchable attachment failure replies error, entry log for media

Formatting like Claude: one list item per line, prompt rule plus post-fix

Review fixes: real audio suffix, no RU marker, transcript cap

Ideal routing: voice transcribed into scenario routing, OR qwen newcomer in light chain

stats: active chats counted over trailing 24h, total kept

Qwen audit fixes: aio Gemini client, snapshot-before-thread state flush, drop dead Fish check, utcnow fix

Merge album-parallel: download album extras in parallel

Stale text: drop dead /model ref from prompt, fix test counts and TTS order notes

Perf: download album extras in parallel, keep message order

Merge guest-hint: DM hint in all 25 langs instead of bare placeholder

Style: informal ty in Russian tiktok strings, regression test

Fix guest hint test: default chat lang is English

Guest TikTok: DM hint in all 25 langs instead of bare placeholder

TikTok music: sound-author handle stripped, performer is sound author, artist suffix trimmed

TikTok music: retry send_audio without thumbnail on failure

TikTok music: unswap TikWM title/author when title is author handle

TikTok UX: localized slideshow status (25 langs), audio duration probe, status lives through music fetch

History summarization: compress overflow into summary instead of silent cut

stats goes pro: hide idle models, per-provider totals and remaining quota

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

Re-audit fixes: typing-indicator regression test, Deno proxy tests in CI

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)

Fix lang reset on restart: keep lang in restored chat state

Fix prod outage: single bot module namespace + skip fil locale in setMyCommands

Revert guest_message removal (valid Bot API Update field, guest mode) + dependabot grouping

Move tests to tests/ and proxy to proxy/, update CI and docs paths
