When a user accumulates `--warn-threshold` warns within `--warn-window`, auto-ban them. Default behavior is unchanged: `--warn-threshold=0` disables the feature, and the existing `/warn` warning-message-and-delete flow continues to work for users who don't opt in. + +This complements the existing `--auto-ban-threshold` (which aggregates user `/report` submissions for one *message*) by adding analogous behavior for admin warns aggregated per *user*. + +## Context (from discovery) + +- **Closest analog** in the codebase: `app/storage/reports.go` (event-log table with cleanup) + `app/events/reports.go executeAutoBan` (auto-ban path triggered by aggregate threshold). +- **Settings layering** (post PR #294, three layers): CLI flags in `app/main.go` → persisted `Settings` struct in `app/config/settings.go` (json/yaml/db tags + `zeroAwarePaths` for fields where 0 means "disabled, do not overwrite") → web UI in `app/webapi/config.go` form parser + `assets/settings.html` inputs. CLI→Settings mapping lives in `app/settings.go optToSettings`. +- **Storage convention**: structs embed both `*engine.SQL` and `engine.RWLocker`, define `migrate` (no-op for new tables) and `Add` that sets `gid` from `r.GID()` and timestamps internally, optionally trigger cleanup inline. +- **Consumer interfaces** for the events layer live in `app/events/events.go`, alongside `Reports`, `Locator`, `Bot`, `TbAPI`. moq-generated mocks go in `app/events/mocks/`. +- **Ban primitives** are shared via `banRequest` and `banUserOrChannel` in `app/events/events.go`; both `executeAutoBan` (reports) and existing admin paths use them. New `executeWarnBan` will use the same primitives — no shared abstraction with `executeAutoBan` (the two diverge meaningfully). + +## Development Approach + +- **Testing approach**: Regular — code + tests in the same task. Tests are mandatory deliverables of every task; no task is complete until its tests pass. +- Complete each task fully before moving to the next. +- Make small, focused changes. +- **Every task MUST include new/updated tests** for code changes in that task. Tests are not optional. +- **All tests must pass before starting the next task** — no exceptions. +- Storage tests must run against both SQLite and PostgreSQL (existing pattern in `app/storage/*_test.go` parameterizes on both). +- Maintain backward compatibility: `--warn-threshold=0` (default) preserves current `/warn` behavior exactly. + +## Testing Strategy + +- **Unit tests** required for every task. +- **Storage tests** parameterized on both SQLite and Postgres (use `engine.NewSqlite` and `containers.PostgresTestContainer` patterns from existing tests). +- **e2e tests**: project has Playwright e2e tests for the web UI (`/cmd/e2e/`). New settings inputs in `settings.html` should be exercised by an e2e case verifying the form persists and reloads the values correctly when running in `--confdb` mode. + +## Progress Tracking + +- Mark completed items with `[x]` immediately when done. +- Add newly discovered tasks with ➕ prefix. +- Document blockers with ⚠️ prefix. +- Update this plan if implementation deviates from the original scope. + +## Solution Overview + +Five wiring layers, in dependency order: + +1. **Storage** (`app/storage/warnings.go`): per-event log table; `Add` writes a row + opportunistically cleans up rows older than the longest reasonable window; `CountWithin` returns the row count for `(gid, user_id)` newer than `now-window`. +2. **Consumer interface** (`app/events/events.go`): `Warnings` interface with `Add` and `CountWithin`; moq mock generated to `app/events/mocks/warnings.go`. +3. **Settings** (`app/config/settings.go`): new `WarnSettings` substruct with `db:"warn_threshold"` and `db:"warn_window"`; `Warn WarnSettings` field on top-level `Settings`; `Warn.Threshold` added to `zeroAwarePaths` so 0 ("disabled") is preserved on settings load. +4. **CLI plumbing** (`app/main.go` flags + `app/settings.go optToSettings`): two new flags, mapped into `WarnSettings` exactly like `Report.AutoBanThreshold`/`History.Duration`. +5. **Handler** (`app/events/admin.go`): `DirectWarnReport` extended — when threshold>0 record warn → count → if `count >= threshold` invoke `executeWarnBan`. New helper bans the user/channel via existing `banUserOrChannel`, respects training/dry/soft-ban, posts an admin-chat notification. **Does not** update spam samples. +6. **Web UI** (`app/webapi/config.go` + `assets/settings.html`): two form fields (`warnThreshold` int, `warnWindow` time.Duration) parsed exactly like `reportAutoBanThreshold` and `reactionsWindow`. + +## Technical Details + +### CLI flag namespacing + +Flags use the project's grouped pattern (matching `Report`, `Files`, `Reactions`, `History`): + +```go +Warn struct { + Threshold int `long:"threshold" env:"THRESHOLD" default:"0" description:"auto-ban after N warns within window (0=disabled)"` + Window time.Duration `long:"window" env:"WINDOW" default:"720h" description:"sliding window for counting warns"` +} `group:"warn" namespace:"warn" env-namespace:"WARN"` +``` + +User-facing names: `--warn.threshold`, `--warn.window`; env vars: `WARN_THRESHOLD`, `WARN_WINDOW`.

So `--warn.threshold=2` means "ban on the 2nd warn within the window". + +### Repeated-ban behavior + +After a ban fires (count=2 with threshold=2), the corresponding warning rows stay in the table. A subsequent `/warn` on the same already-banned user will find count=3 ≥ 2 and re-trigger the ban path. Telegram's `BanChatMemberConfig` is idempotent (banning an already-banned user is a no-op), so this is safe and intentional — no row deletion on ban. The repeat ban posts a fresh admin notification, which serves as audit/visibility for repeat offenders. + +### Cleanup + +`Warnings.Add` opportunistically deletes rows where `created_at < now - 1y` to keep the table small.

A notification is posted to the admin chat in the form `**warn auto-banned** @user (12345) after N warns within `. The verb adapts to the active mode: `auto-would have banned` in dry mode, `auto-would have banned (training)` in training mode, and `auto-restricted` for users in soft-ban mode (channels still fall through to `auto-banned` because Telegram has no restrict variant for channel senders). -Example: `--warn.threshold=3 --warn.window=168h` bans a user once they accumulate three warnings within a week. +Example: `--warn.threshold=3 --warn.window=168h` bans a user once they accumulate three warnings within a week (the third warn triggers the ban). Notes: - The default `--warn.threshold=0` preserves the original `/warn` behavior exactly: a warning message is posted and the offending message is deleted, but no warning is recorded and no auto-ban is performed. -- Warnings issued before the window expires are counted; older rows are pruned opportunistically by the storage layer (storage cap is one year, independent of the configured window). +- Warnings issued before the window expires are counted; older rows are pruned opportunistically by the storage layer. The storage retention is capped at one year, so configuring `--warn.window` beyond `8760h` is not supported. - Unlike `/spam`, `/warn` does not update spam samples — warnings reflect admin policy, not spam content. - Repeat bans are intentional: if an already-banned user is warned again, the threshold check fires again and re-bans them. Telegram treats banning an already-banned user as a no-op, so this is safe and serves as audit visibility for repeat offenders. +- Toggling `--warn.threshold` from `0` to a positive value (or vice versa) requires a process restart: the warnings storage is wired only at startup. Runtime changes via the settings UI are persisted but take effect only after the next restart. ### Lua Plugins Support diff --git a/app/events/admin.go b/app/events/admin.go index 0e3d4ff4..9cdc3f13 100644 --- a/app/events/admin.go +++ b/app/events/admin.go @@ -346,17 +346,17 @@ func (a *admin) DirectWarnReport(update tbapi.Update) error { } // make a warning message and replay to origMsg.MessageID - warnTarget := "@" + origMsg.From.UserName + warnTargetName := "@" + origMsg.From.UserName if origMsg.SenderChat != nil && origMsg.SenderChat.ID != 0 && origMsg.SenderChat.ID != a.primChatID { chName := a.channelDisplayName(origMsg.SenderChat) if origMsg.SenderChat.UserName != "" { - warnTarget = "@" + chName + warnTargetName = "@" + chName } else { - warnTarget = chName + warnTargetName = chName } } warnMsg := fmt.Sprintf("warning from %s\n\n%s %s", update.Message.From.UserName, - warnTarget, a.warnMsg) + warnTargetName, a.warnMsg) if err := send(tbapi.NewMessage(a.primChatID, escapeMarkDownV1Text(warnMsg)), a.tbAPI);

Without this, a persisted negative would silently enable ban-on-every-warn. - main.go: validateSettings rejects `warn.threshold < 0` at startup (fail-fast on CLI typos). - README: drop stray help-output formatting in flag references.
