Ragnor Comerford 7fc00142a4 engine: scope refresh() write guard to recovery; release before schema reload ... Closes the HIGH-severity deadlock flagged by Cursor Bugbot on PR #75 review of commit b09a097. Pre-fix: `Omnigraph::refresh()` held `coordinator.write().await` from omnigraph.rs:468 through function exit, including across the call to `reload_schema_if_source_changed()` at line 484. That helper's `self.coordinator.read().await` (only reached when on-disk schema source differs from in-memory cache) deadlocked against the outer write guard because tokio's RwLock is non-reentrant. Reachable from `branch_delete` (omnigraph.rs:910) and `branch_merge` (post-merge refresh at merge.rs:1100). Cross-handle scenario: handle A calls apply_schema, handle B's stale cache hits the reload path on its next refresh. Why correct by design (AGENTS.md rule 9): the write guard's purpose is to serialize the recovery sweep's mutation of GraphCoordinator; the schema reload reads coord.branch_list() and stores into the ArcSwap'd schema_source / catalog without touching the coord. The two operations have disjoint lock requirements; coupling them was over-locking. Scoping the guard matches the natural data-flow: snapshot recovery state under the write, release, then reload schema using a fresh read on the same lock. Pinned by `composite_flow_schema_apply_then_branch_ops_no_deadlock_in_refresh` (previous commit). Pre-fix: 15s timeout fires. Post-fix: completes in 0.25s. Both other composite_flow tests still pass: canonical_lifecycle and multi_branch_sequential_merges. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>		2026-05-08 17:47:08 +02:00
