§8 item 6: distributed system safety — concurrency scenarios passed/failed, lost-updates, deadlocks, orphans, and conflict-resolution. These 6 metrics light up one by one as Wave 6's collector lands. Today: 0 pending, 6 live.

Concurrency Scenarios

24/24 consistent

24-way contention · 151.9 ops/s · p95 123ms

Lost-Update Detection

0 lost

seen_count == workers under 24-way ON CONFLICT contention

Deadlock Prevention

0 deadlocks

no worker errored under 24 concurrent conflicting RPCs

Orphan Cleanup

5/5 graceful

chaos: dangling/orphan + denormalisation-drift reads degrade, never 500

Conflict Resolution

append-only ✓

audit ledger grew by exactly 24 (append-only invariant)

Race Condition Tests

none detected

snapshot stays well-formed jsonb throughout concurrent mutation

5762 tests passing across 519 files · 94 migrations
