BREAKING CHANGE: the Go module path is now github.com/tiennm99/tiennm99bot,
the default sticker pack is stickers_by_<bot username>, and the health body,
deploy DM, User-Agents and image names say tiennm99bot.
/random, /wheelofnames, and /gacha move from misc into a new random module
with unchanged command names, so usage stats carry over. The new unlisted
/gachabeta takes the same input as /gacha and renders the toon-shaded beta
wish from /api/gachabeta on the same service, with the same text fallback.
Rarity is now a leading prefix such as "4* Pho" or "3* Rice"; options
without one are 5 stars. This replaces the trailing "*5" tag and its
3-star default.
Options take an optional *4 or *5 rarity tag; untagged options are 3 stars.
A pick rolls a tier at Genshin base rates over the tiers present, then an
option uniformly within it, so untagged input matches /random. The wish
animation renders as MP4 on the wheelofnames service at /api/gacha, with a
text fallback when the renderer is unset or fails.
Correct comments that described the retired webhook transport, a removed
/cron route, the old KV store and wrapper types, and behaviour that has since
changed; drop plan and review labels; reword two startup log lines that
overstated or misnamed what they report.
Sequel to /ff: the same fan who panicked and surrendered mid-series now
files an administrative petition because the team came back. Punchlines
are quoted back as the sender's own words and retracted rather than
asserted fresh.
Shaped as a Vietnamese đơn từ parody — quốc hiệu, Kính gửi, Nội dung sự
việc, Tôi xin cam kết, signature block — since the joke is the
bureaucratic form, not the wording. Carries no scoreline or title count
so it does not go stale next split.
Reuses senderMention for the Tôi tên là field and the signature, which
made the trongTruongHopUpdate test helper name wrong; renamed it
messageFrom now that two command families share it.
A remote wheel render takes several seconds, during which /wheelofnames
looked unresponsive. Post "Spinning..." first, then let the result take
its place: the GIF replaces it (send-then-delete, since Telegram cannot
edit text into media) and any render or upload failure edits the same
message into the plain text winner. A rejected edit still falls back to a
fresh reply so the chat never stays stuck on "Spinning...".
No placeholder when no renderer is configured — the winner reply is
already immediate there and would only flash.
Adds SendText/EditText/DeleteMessage to chathelper; Reply now delegates
to SendText.
Replies with a fixed Vietnamese copypasta for when T1 starts losing, built
from the local community's running jokes. Protected, so it stays out of the
public command menu like the other gated commands.
Delete the byte-oriented KVStore/VersionedStore abstraction and the
DynamoDB/memory KV backends. Add a generic typed store (DocStore[T] with
Provider/Collection/Typed) persisting each value as a flattened native
Mongo document (storedDoc[T] via bson inline) — no value envelope.
- MongoDB is the only runtime backend; memory kept for tests/local.
- All modules + deploynotify use typed stores; persisted structs carry
bson tags == json names (incl. nested lolschedule/wordle types).
- lolschedule wraps its array/scalar values in named structs.
- migrate-dynamo-to-mongo writes the flattened shape via Typed[bson.M]
with wrap rules; Scan/--dry-run/--verify retained.
Verified: go vet/build clean; full go test green hermetically and
in-container vs real Mongo 7 + DynamoDB Local (storage integration +
migrator e2e).
The CF→AWS data migration (closed 2026-05-16) is long done and the
tooling isn't wired into any production path. Remove the one-shot binary,
its support package, and the migration runbook.
In live code, replace 'JS-parity' / 'same shape as JS' / 'cross-runtime
KV migration' comments with the real, stable reason for each behavior
(wire-format invariant, null-vs-zero distinction, CloudWatch alarm field
name, etc.). 24 files touched across lolschedule, loldle, wordle, twentyq,
trading, misc, util, server, metrics, ai, keylock.
- delete cmd/migrate_cf_data/
- delete internal/migration/
- delete docs/cf-to-aws-migration-runbook.md
Vietnamese disclaimer one-liner. Interpolates a target name (default "VNG")
and the sender — @username when set, else tg://user?id link with the display
name. User-supplied text HTML-escaped; reply routed through ReplyHTML to keep
forum-topic threading.
Concurrency
- lolschedule: serialize subscriber Get→mutate→Put via state.subscribersMu;
the single-slot list was previously losing writes under concurrent
/lolschedule_subscribe.
- trading: PriceClient memoises its default *http.Client so /trade_stats
reuses TLS connections across held tickers.
Observability
- server/log_middleware: defer the req log line and recover panics so a
panicking cron handler still emits the structured req entry CloudWatch
filters on for 5xx alerting.
- server/router (cron): inner recover with cron-name context captures the
panicking job before the middleware's safety net does.
- telegram/webhook: rune-safe truncation in dispatch logs — Vietnamese,
Korean, and emoji previews no longer ship as garbled bytes.
- lolschedule/api_client: same rune-safe fix for error-body log truncation.
- telegram/webhook: gate the post-recover WriteHeader(200) so a panicking
handler that already touched w doesn't trigger superfluous-WriteHeader.
Correctness
- twentyq: clearGame error during solved-relaunch is logged instead of
silently swallowed (was a permanent deadlock vector on KV failure).
- misc /mstats: KV read failure replies "Could not load stats. Try again
later." to the user instead of returning into the dispatcher; matches the
pattern other modules use.
- migrate_cf_data trading-audit-dump: surface f.Close error so a truncated
JSONL never passes silently as a complete audit dump.
Operator ergonomics
- migrate_cf_data (all 4 subcommands): signal.NotifyContext for SIGINT /
SIGTERM. Ctrl-C mid-Scan now propagates cleanly instead of leaving a
half-converted DynamoDB table.
- ai/ratelimit: doc the Lambda-recycle memory bound to match keylock.Map
so a future reviewer doesn't re-flag the unbounded map.
I/O-changing (user-approved)
- lolschedule daily push auto-prunes subscribers whose Telegram error
matches a terminal marker (blocked / deactivated / chat gone). Transient
errors keep the chat on the list. Subscribe message updated to mention
the auto-cleanup.
- twentyq seed pool grown 50 → 178; repeat-collision threshold moves from
~9 plays to ~17 (birthday paradox).
- util /info flipped Public → Protected — chat/thread/sender IDs are no
longer enumerable by every group member.
- cmd/server WriteTimeout 6min → 75s (cron 60s + 15s slack). No-op on
Lambda; matters only for local non-Lambda runs.
- webhook + cron rejection paths drop response bodies (no fingerprintable
text for internet scanners hitting the public Function URL). Status
codes preserved for CloudWatch metrics; structured log lines carry the
rejection reason for operator triage.
Tests added: TestTruncateRunes, TestRunDailyPush_PrunesDeadSubscribers,
TestIsTerminalSendError, TestInfo_DeniedToNonOwner,
TestInfo_DeniedToChannelMessageNoFrom, plus owner-allowed counterparts.
Telegram routes outgoing messages with no message_thread_id to a forum
supergroup's General topic. Commands sent in a topic were being answered
in General. chathelper.Reply / ReplyHTML now take *models.Message and
forward both ChatID and MessageThreadID; help.go SendMessage and
loldle trySendSticker do the same. Adds regression tests asserting the
field is forwarded for forum topics and omitted for private/regular groups.
