Two related Telegram changes:
1. Per-chat command localization. setMyCommands now accepts a scope
(BotCommandScopeChat) and deleteMyCommands clears scoped bindings.
Command registration runs three tiers: default → per-language
(Telegram client language) → per-chat (UI override). Saving a
chat's language_override or commands_enabled toggle pushes the
binding to Telegram inline rather than waiting on the 30s
debounced bot-wide sync.
2. Unified Telegram locale resolution. Three test paths (bot test_chat,
target receiver test, target-level fan-out) used to disagree on
locale priority — the target receiver test in particular only
consulted receiver.locale and ignored the chat's language_override.
Introduced pick_telegram_locale (pure) and
resolve_telegram_chat_locale (async DB lookup) in services/notifier
so all three paths share one priority order:
receiver.locale → chat.language_override → chat.language_code → fallback
Fan-out keeps batch-loading TelegramChat rows for efficiency, just
runs them through the same priority function now.
- Introduce Receiver base class + typed subclasses (TelegramReceiver,
WebhookReceiver, EmailReceiver, etc.) in core/notifications/receiver.py
- Dispatcher uses typed Receiver objects instead of raw dicts, with
per-receiver locale-aware template rendering
- load_link_data resolves locale from TelegramChat.language_override at
load time: TargetReceiver.locale || chat.language_override || chat.language_code
- Add language_override field to TelegramChat (separate from auto-detected
language_code), with per-chat commands toggle and command dispatch using
override language
- Add locale field to TargetReceiver for explicit per-receiver overrides
- Discord, Slack, ntfy, Matrix notification target types with clients and dispatch
- MatrixBot model + API + frontend in Bots tab
- Command template system fully wired into all handler commands
- Default command templates seeded (EN/RU, 14 slots each)
- Command template editor with variables reference including child fields
- Delete protection on all 10 entity types (409 with consumer details)
- Provider type selector on template config forms
- Target type selector as dropdown with all 7 types
- Response template selector on command config form
- CLAUDE.md: mandatory server restart rule, child properties rule
