In 2026.2.13, the combination of implicit reply threading (#14976) and
the existing Telegram default replyToMode="first" causes every bot
response in DMs to be sent as a native Telegram reply (quoted message
bubble), even for simple exchanges like "Hi" → "Hey".
This is a UX regression: prior to 2026.2.13, reply threading was less
consistent so the "first" default rarely produced visible quote bubbles
in DMs. Now that implicit threading works reliably, the default
effectively means every first message in a response gets quoted —
which feels noisy and unexpected in 1:1 conversations.
Changing the default to "off" restores the pre-2026.2.13 DM experience.
Users who want reply threading can still opt in via config:
channels.telegram.replyToMode: "first" | "all"
Tested by toggling replyToMode on a live 2026.2.13 instance:
- replyToMode="first" → every response quotes the user message
- replyToMode="off" → clean responses without quote bubbles
No test changes needed: existing tests explicitly set replyToMode
rather than relying on the default.
* fix: use .js extension for ESM imports of RoutePeerKind
The imports incorrectly used .ts extension which doesn't resolve
with moduleResolution: NodeNext. Changed to .js and added 'type'
import modifier.
* fix tsconfig
* refactor: unify peer kind to ChatType, rename dm to direct
- Replace RoutePeerKind with ChatType throughout codebase
- Change 'dm' literal values to 'direct' in routing/session keys
- Keep backward compat: normalizeChatType accepts 'dm' -> 'direct'
- Add ChatType export to plugin-sdk, deprecate RoutePeerKind
- Update session key parsing to accept both 'dm' and 'direct' markers
- Update all channel monitors and extensions to use ChatType
BREAKING CHANGE: Session keys now use 'direct' instead of 'dm'.
Existing 'dm' keys still work via backward compat layer.
* fix tests
* test: update session key expectations for dmdirect migration
- Fix test expectations to expect :direct: in generated output
- Add explicit backward compat test for normalizeChatType('dm')
- Keep input test data with :dm: keys to verify backward compat
* fix: accept legacy 'dm' in session key parsing for backward compat
getDmHistoryLimitFromSessionKey now accepts both :dm: and :direct:
to ensure old session keys continue to work correctly.
* test: add explicit backward compat tests for dmdirect migration
- session-key.test.ts: verify both :dm: and :direct: keys are valid
- getDmHistoryLimitFromSessionKey: verify both formats work
* feat: backward compat for resetByType.dm config key
* test: skip unix-path Nix tests on Windows
Fixes#9545 and #9351.
When a message comes from a Telegram forum topic, the peer ID includes
the topic suffix (e.g., `-1001234567890:topic:99`). Users configure
bindings with the base group ID, which previously did not match.
This adds `parentPeer` to `resolveAgentRoute()` calls for forum groups,
enabling binding inheritance from the parent group to all topics.
- Extract `buildTelegramParentPeer()` helper in bot/helpers.ts
- Pass parentPeer in bot-message-context.ts, bot-handlers.ts,
bot-native-commands.ts, and bot.ts (reaction handler)
- Add tests for forum topic routing and topic precedence
* Telegram: remove @ts-nocheck from bot.ts and bot-message-dispatch.ts
- bot/types.ts: TelegramContext.me uses UserFromGetMe (Grammy) instead of manual inline type
- bot.ts: remove 6 unsafe casts (as any, as unknown, as object), use Grammy types directly
- bot.ts: remove dead message_thread_id access on reactions (not in Telegram Bot API)
- bot.ts: remove resolveThreadSessionKeys import (no longer needed for reactions)
- bot-message-dispatch.ts: replace ': any' with DispatchTelegramMessageParams type
- bot-message-dispatch.ts: add sticker.fileId guard before cache access
- bot.test.ts: update reaction tests, remove dead DM thread-reaction test
* Telegram: remove duplicate bot.catch handler (only the last one runs in Grammy)
* Telegram: remove @ts-nocheck from bot.ts, fix duplicate error handler, harden sticker caching (#9077)
Regular Telegram groups (without Topics/Forums enabled) can send
message_thread_id when users reply to messages. This was incorrectly
being used to create separate session keys like '-123:topic:42',
causing each reply chain to get its own conversation context.
Now resolveTelegramForumThreadId only returns a thread ID when the
chat is actually a forum (is_forum=true). For regular groups, the
thread ID is ignored, ensuring all messages share the same session.
DMs continue to use messageThreadId for thread sessions as before.
- Add bot.catch() to prevent unhandled rejections from middleware
- Add isRecoverableNetworkError() to retry on transient failures
- Add maxRetryTime and exponential backoff to grammY runner
- Global unhandled rejection handler now logs recoverable errors
instead of crashing (fetch failures, timeouts, connection resets)
Fixes crash loop when Telegram API is temporarily unreachable.
