bdcf793db2
Phase 2 (Integration + Tech-Debt + NFR Measurement) complete. 4 slices, 2 waves, 9 tasks. 4 REQs covered. 60 new tests (469 total). 8 v0.4 P1+ tech-debt findings addressed. Verify: APPROVE_WITH_NOTES. NFR measurement (p95 latency + guardrail FP/FN), cohort aggregation assist metrics (5 new metrics, no schema change), assist cost tracking + C-3 budget check, tech-debt wave (argon2id offload, cookie-secret validation, credential enum, f-string SQL, cache persistence, zoneinfo, audit log, 429 mock). ---ci--- project: praxis phase: 2 milestone: v0.5 status: complete requirements: covered: [REQ-NFR-ASSIST-01, REQ-IDEATE-04, REQ-IDEATE-06, REQ-IDEATE-07] partial: [] ---/ci---

"""GET /api/operator/failure-patterns — failure patterns + safety signals (TASK-08-03, TASK-10-02, D-053).
|
|
|
|
Auth-gated. Returns failure pattern metrics: failure_mode frequency (cells
|
|
with metric prefix `failure_mode:`) + branch outcome distribution (cells
|
|
with metric prefix `branch:`) + the assist guardrail block rate safety signal
|
|
(TASK-10-02 — `assist_guardrail_block_rate`). Weak-spot rubric criteria
|
|
(mean < 3.0) are highlighted by the frontend. All k-anonymized.
|
|
|
|
The `assist_guardrail_block_rate` is a safety signal for operators: a sudden
|
|
spike signals either a prompt regression or learners pushing boundaries. High
|
|
block rate = flag for operator review.
