Will Pfleger	020193f8e3	feat(relay): add direct staff ban/timeout/delete with staff guard (#7883) ... Relay staff (the `RELAY_OPERATOR_PUBKEYS` config roster, the owner fallback, and DB operator/moderator rows) can now ban, time out, and delete without a report through the admin API. Staff never join the community transport: these are admin-host, NIP-98 signed routes that drive the existing report enforcement state machine. Community admission, bans, and right-click menus are unchanged from `main`. Stack: this PR → #7904 ## Routes | Route | Body | |---|---| | `POST /api/admin/v1/members/{pubkey}/ban?communityHost=` | `{requestId, reason?}` | | `POST /api/admin/v1/members/{pubkey}/timeout?communityHost=` | `{requestId, expirationSecs, reason?}` | | `POST /api/admin/v1/events/{eventId}/delete?communityHost=` | `{requestId, reason?}` | Responses: `200 {actionId, state: "succeeded", replayed}`, `202 {state: "pending"}` when the action is accepted but not yet converged (the recovery worker finishes it; the same `requestId` replays), `409 request_id_conflict`, `409 target_is_staff`, `404 event_not_in_community`, `400 invalid_community_host` / `unknown_community_host`, and `422 enforcement_failed`. `422` is now the single failed-enforcement code for both the report and direct paths (shared `enforcement_failed()` mapping). ## Design - **Migration 0055.** `relay_admin_actions.report_id` becomes nullable. A direct row has `report_id NULL`, and `report_community_id` stays the tenant. New columns: `enforcement_target_event_id` and `timeout_secs`. The `relay_admin_actions_direct_shape` CHECK spells out each direct action: timeout needs both `timeout_secs` and `timeout_until`, ban and delete need neither, and delete needs both the event id and the author. A partial unique index on `(report_community_id, request_id) WHERE report_id IS NULL` makes direct actions idempotent. `pgschema` drops multi-column CHECKs, so `scripts/reconcile-schema-after-pgschema.sql` re-adds `relay_admin_actions_direct_shape` on desired-state databases. - **Atomic acceptance.** `claim_direct_action` inserts the action row and its `moderation_actions` audit row (`ban` / `timeout` / `delete_message`, `relay_operator` / `relay_moderator`) in one transaction. `ON CONFLICT DO NOTHING` sends a concurrent same-key request to the comparison. Retries compare actor, action, reason, `timeout_secs`, and the client-named target: the event id for delete, the pubkey otherwise. The event author, channel, and `timeout_until` are derived at acceptance and never compared. - **Retry racing its own first attempt.** Handler order: stored-action lookup → validation → staff guard → accept. If validation fails (for example B's event lookup runs after A already deleted the event), the handler re-reads the stored action. It returns a replay or 409 rather than 404. - **Report-less enforcement.** `finalize_success(report_id: Option<Uuid>)` skips the report CAS and the `reporter_notice` for direct actions. Tombstone and affected-user notices are unchanged. `recover_one` drives a direct action from its persisted row. `deliver_reporter_notice` treats a missing `report_id` as a terminal error instead of panicking. - **Permanent bans clear old expiry.** The ban upsert shared by direct and report-backed bans sets `ban_expires_at = NULL`, matching the kind-9040 path, so a permanent ban over an active or lapsed timed ban is in effect with no deadline. Timeouts are untouched. - **Community purge removes admin-action rows.** `purge_postgres` deletes the community's `relay_admin_outbox` rows (joined through their action), then its `relay_admin_actions` rows by `report_community_id`, before `moderation_reports`. That order satisfies both FKs and covers report-backed and direct (`report_id NULL`) rows in one pass. The same keyed row sources (`RELAY_ADMIN_TABLES`) feed the deletion inventory, which now records row counts for both tables, and post-purge logical verification, which now fails if either table still has a row for the community. Before this, a community with any admin-resolved report could never finish deletion (23503 on `relay_admin_actions_report_community_id_report_id_fkey`, stuck at `bindings_removed`). The `_operator_global_tables` registry reasons for both tables (seeded in migration 0036) are updated in 0055 and `schema.sql` to say community deletion purges them explicitly. - **Staff bans disconnect clusterwide.** The shared enforcement driver (`drive_enforcement`, used by the report and direct paths, fresh and recovery) calls `disconnect_pubkey_clusterwide` for `ban` before finalizing, matching the kind-9040 ban. A crash before finalize leaves the action non-terminal, so recovery re-runs the disconnect (idempotent) even when the ban step marker is already set. Timeouts do not disconnect, matching in-community timeout. - **Staff guard (D2).** `lookup_admin_principal` returns `Result<Option<AdminPrincipal>>`, with the same precedence as `resolve_admin_principal` (now a wrapper). `Ok(None)` means not staff. A roster lookup error is a 500, so the guard fails closed. Ban and timeout (direct) and ban/timeout/kick (via `resolve_report`) refuse any effective-roster target with `409 target_is_staff`, including the actor. The report path refuses before claim, so the report stays `open`. Delete is not guarded on either path. The check runs only when an action is first accepted: a replay or crash recovery completes an accepted action even if its target became staff afterwards. - **`communityHost` grammar (D4).** `buzz_core::tenant::validate_community_host` accepts only DNS labels and an optional port, and rejects schemes, paths, queries, userinfo, IP brackets, and whitespace before tenant binding. ## Tests binding fixes (red under mutation → green) Postgres tests are in `api/admin/mod.rs` `postgres_tests`, run against a DB migrated through 0055. Every rejection test seeds an existing restriction and asserts, through the shared `assert_no_effects` helper, that restriction values and action/audit/outbox/restriction/event counts are unchanged. | Fix | Test | Mutation → red | |---|---|---| | Racing retry replays | `direct_delete_retry_racing_first_attempt_replays_not_404` (barrier-paused HTTP interleaving;

Luke Tornquist	0ccf934b88	fix(db): disable heartbeat vacuum truncation (#6898) ... ## Why `replica_heartbeat` is updated continuously, but autovacuum heap truncation can take an `ACCESS EXCLUSIVE` lock whose replay cancels concurrent hot-standby reads. Truncating a fixed, single-row table provides no meaningful space benefit. ## What - Add migration 0034 to set `vacuum_truncate = false` on `replica_heartbeat` - Keep the desired-state schema aligned for fresh installations - Extend migration coverage so both paths retain the reloption ## Risk Assessment Low — this disables only autovacuum's heap-truncation phase for a single-row table; normal vacuum cleanup remains enabled. The tradeoff is retaining at most the table's otherwise-truncatable tail pages. ## References - [Investigation thread](https://sq-block.slack.com/archives/C0B2WT43BDH/p1787760831375989) - [PostgreSQL table storage parameters](https://www.postgresql.org/docs/current/sql-createtable.html#SQL-CREATETABLE-STORAGE-PARAMETERS) Generated with Codex --- **Update Aug 27, 2026:** Hardened fresh `pgschema` bootstraps after review. - Renamed the shared post-apply script to `reconcile-schema-after-pgschema.sql` and made it restore the heartbeat reloption and singleton row idempotently. - Added live catalog and row assertions that stop bootstrap when the database does not match the required state. - Updated every repository `pgschema apply` caller, including the desktop release smoke path. - Added a regression test that requires future `pgschema apply` callers to run reconciliation. - Documented the `pgschema` DML and storage-parameter limitation in `AGENTS.md` and at the reconciliation entry point. - Merged current `main` and renumbered this migration to 0034 after `main` added migration 0033. --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com>	2026-08-27 13:01:13 -04:00
