From 698049d6270ea492e2d1ee7f8dfad92a3ced6015 Mon Sep 17 00:00:00 2001 From: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 Date: Thu, 30 Jul 2026 19:33:03 -0400 Subject: [PATCH] fix(managed-agents): enforce fail-closed per-scope barrier before flush MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a per-scope readiness latch (config_sync_ready_scope in AppState) that the flush loop checks before publishing any row. Before this, the flush loop ran independently of the boot barrier, so legacy pending rows from a prior boot were publishable at t≈0 — before reconcile or barrier had run — recreating the stale-store revert this PR exists to close. Changes: - Add publish_blocked field to RetainedEvent and carry it in all query sites (get_pending_sync, get_retained_event, get_retained_personas, legacy_migration reader). New rows start publish_blocked: false; the barrier sets it via set_publish_blocked. - Add config_sync_ready_scope: Mutex> to AppState. Starts None. Set to Some(db_path) by run_boot_barrier on successful completion; never set on any error path. - flush_active_pending_events checks readiness before snapshotting pending rows. If not ready it runs run_boot_barrier inline, then re-checks: a barrier failure skips this tick and retries on the next, so a transient relay-unreachable at boot does not wedge publishing for the session. - flush_pending_events_at re-reads publish_blocked immediately before submit_signed_event_at_with_keys. A row gated after the pending snapshot was taken cannot publish. - apply_workspace clears config_sync_ready_scope to None before spawn_event_sync so a workspace switch lands unready until its own barrier passes. - Remove the 'in practice' timer-luck paragraph from event_sync.rs; replace with the enforced structural invariant. - Remove all writer-consistent and sync_authoritative references from desktop/src-tauri; replace with exact, best-available, replica-lag-exposed language. Grep acceptance: empty. - Add three deterministic tests in flush_barrier module: (a) test_row_gated_after_snapshot_cannot_submit: barrier gates a row after the pending snapshot; flush sees publish_blocked on re-read and skips it; row stays pending. (b) test_barrier_error_leaves_scope_unready: latch starts None, stays None until barrier succeeds, cleared on workspace switch. (c) test_retry_path_publishes_after_barrier_succeeds: latch None → scope not ready; latch set → flush proceeds and row publishes.
