Its listen address is configured via `GatekeeperWebApp.ListenAddr`. In the Docker deployment it binds `0.0.0.0:8080` inside the container (mapped to `127.0.0.1:18080` on the host); the default **must NOT** be changed to loopback or the container port mapping breaks. - **No-Rights Mode** 🛡️: Before banlist, LLM, reaction, or voting moderation, check the bot's restrict-member capability. A confirmed Telegram privilege error is terminal and must not be retried. Public CAPTCHA may still run without restricting the user: success deletes the CAPTCHA; failure leaves a durable 30-minute notice. - **Manual Allowlist Priority** ✅: A matching per-chat `chat_not_spammer_overrides` row is the only exemption checked before cached or provider-backed banlist enforcement. For every non-allowlisted user, effective banlist membership remains an unconditional deny decision before remembered membership, admin status, commands, voting, or LLM. The always-on cached guard precedes the configured `admin → gatekeeper → reactor` chain, and join updates are checked even when Gatekeeper is disabled. Enforcement directly bans and deletes the available join/current-message artifact without creating a spam case. The guard may inspect the in-memory effective set to short-circuit routing, but it must verify moderation capability before Telegram I/O and must not perform online provider checks in no-rights mode. Allowlist lookup failures fail closed and continue normal moderation. -- **Durable Message Probation** ✏️: A previously untrusted author gets a per-chat durable probation on the first message. Check every new text, caption, or visible `RichMessage` text for the configured minimum duration, then require a distinct safe new message to graduate; commands and empty media start the clock but cannot graduate it. Persist every safe message as `{chat_id, message_id, user_id}` for later edit checks. While probation is active, every authored edit with semantic text is rechecked even without an existing binding, never extends the deadline, and never graduates the author; after graduation, bound-message edits remain protected. Reactions and `chat_known_non_members` never grant message trust. Telegram Bot API has no deletion update for ordinary group messages (`deleted_business_messages` is business-only), so never claim immediate deletion detection. The cached banlist guard applies to all authored edits unless the author has a matching manual allowlist override. +- **Durable Author Trust** ✏️: All chats use a typed `MessageAuthor` (`user` or `sender_chat`); `SenderChat` takes precedence over technical `From`. Three distinct safe new semantic messages grant 30 days of per-chat trust by default; one safe new message renews expired trust. SQLite atomically binds checked messages, increments the counter and grants trust. Membership bookkeeping is separate and best effort after persistence; reactions and `chat_known_non_members` never grant trust. Commands, bot mentions, empty media, reactions and edits never advance or renew admission. Before admission and after expiry all semantic edits are checked; during trust previously bound edits remain protected. Checked-message bindings are durable identity metadata: never expire them with context or trust, because renewal would otherwise make old checked edits unprotected; chat deletion may cascade them. Pending/resolving cases suspend trust; confirmed spam resets it, false positives retain any previous unexpired grant. Channels follow community voting without a mute or technical-user fallback. Keep user allowlist-before-banlist priority; user banlists never consume channel IDs. Preserve linked-channel and anonymous group-admin exemptions. +- **Bounded Conversation Context** 💬: Persist message context separately from author trust in SQLite. Retain original send time, thread/reply links, edited text and Telegram update IDs for same-second edit ordering; snapshots cannot supersede newer authoritative edits. Use only same-chat/thread history younger than 24 hours, at most five earlier replies, 2,000 characters per saved text and 8,000 extra context characters. Prioritize direct reply/quote, source post, then nearby replies. Unknown discussion threads use reply chains, ordinary groups may use recent group history. Successful bot deletions leave short-lived tombstones. Successful user bans that revoke messages clear the matching user context; channel bans do not imply removal of previous channel messages. CAPTCHA context cleanup uses a distinct durable phase so a SQLite retry cannot repeat a completed ban. Ordinary user deletions are not reliably observable through Bot API. Pass history as untrusted structured evidence and classify only the candidate. Never log message texts. No external-reply automatic verdict. +- **Author Trust Configuration** ⚙️: Global `NG_SPAM_SAFE_MESSAGES_REQUIRED` and `NG_SPAM_AUTHOR_TRUST_DURATION` default to `3` and `720h`. Keep the existing per-chat LLM switch. `NG_SPAM_MESSAGE_PROBATION_DURATION` is accepted as deprecated with a warning and has no effect. Migrate prior effective user trust for 30 days from migration, including suspended grants; active probations restart at zero and reaction-only records are excluded.
