PERTAIN_TOReport

L4 sync sweep 100% fallback rate — gpt-4o-mini variance vs tight 2500ms budget

PERTAIN_TORootCause

AbortSignal.timeout(2500) — scanLayer4Sync() in packages/privacy/src/api-helpers.ts wraps a fetch to OpenAI chat/completions (model: gpt-4o-mini). Tension: On timeout it returns { findings: [], timedOut: true } and the caller commits the row as privacy_review_status='pending' and enqueues an async sweep. Outcome: when the sync call SUCCEEDS, OpenAI gpt-4o-mini returns in 1.6–1.9s.

PERTAIN_TOProblem

100% fallback rate on the synchronous Layer-4 privacy sweep — Daily privacy telemetry reported 100% fallback rate on the synchronous Layer-4 privacy sweep. Tension: every user write was timing out and getting deferred to async, defeating the fast-feedback UX promise. Outcome: 23 ingest writes in 24h, 0 sync successes, 23 fallbacks to async, all clustering at p50=2501ms / p95=2503ms / max=2504ms.

PERTAIN_TOSolution

Plumb environment variables for runtime tuning without code changes. Tension: Keep the spec default at 2500ms (preserves the documented contract); override per-environment via env. Outcome: L4_SYNC_TIMEOUT_MS=4000, PRIVACY_SWEEP_BATCH_SIZE=50, PRIVACY_SWEEP_POLLING_S=3.
