feat(routing): opt-in observed-outcome health quarantine before candidate selection - #1221
seonghobae wants to merge 7 commits into
Conversation
…tion Adds TaskOrchestrator(observed_health_quarantine=False). When an operator enables it, served-request outcomes weight the per-agent breaker by failure class: a slow post-send failure (timeout, dropped connection, 408/502/504) demotes the member behind healthy siblings for the next request; two slow (or three fast) failures or a >=60% windowed failure rate quarantine it for a cooldown longer than one failing attempt (360 s); a half-open probe recovers it or re-opens with a doubled, capped cooldown; an all-open pool falls back least-recently-failed first. The default stays the legacy 3/30 breaker per the 2026-09-07 no-heuristics boundary in product-technical-gap-baseline.md; flag-off changes are observability only (circuit_opened fields, all-open fallback log line, routing_evidence.health snapshot). State stays in memory under the existing lock; timeouts, retry/replay authorization, 413/429 handling and model defaults are unchanged. scripts/replay_health_quarantine.py replays the 101 sanitized Noema sidecar logs through the same breaker code (flag off reproduces the deployed breaker with 0 skips); the doctoring runbook records RED/GREEN, replay results, limits and owner decisions.

Exact-head finding (8ffd6531750f834fabbd2188446d69b034be5311): half-open recovery가 현재 후보 정렬과 결합되면서 정상 secondary가 계속 성공하면 primary가 영구적으로 half-open/demoted 상태에 머물 수 있습니다. _circuit_open()은 cooldown 만료 시 health["half_open"] = True로 바꾸고 eligible로 되돌리지만, _order_by_observed_health()는 half_open인 agent를 healthy agent 뒤로 보냅니다. 이후 앞의 healthy agent가 계속 성공하면 failover가 일어나지 않으므로 half-open agent에는 실제 probe가 한 번도 가지 않고, _record_success()도 호출되지 않아 half_open/demotion이 해제되지 않습니다. 문서의 “cooldown 뒤에는 half-open probe를 보낸다 / 성공하면 회복” 계약과 현재 실행 의미가 다릅니다.
현실적인 RED를 먼저 고정해 주세요. preferred A가 slow failure로 open → clock을 cooldown 뒤로 이동 → secondary B가 계속 성공하는 요청을 여러 번 보내는 fixture에서, 현재 head는 A에 probe를 한 번도 보내지 않고 circuit_health_snapshot()[A]["state"] == "half_open"이 계속 유지되는지 확인하면 됩니다. 이 상태는 장애가 해소된 A의 capacity/우선순위를 무기한 회복시키지 못해, B가 quota/비용/지연 측면에서 더 나쁜 경우 buyer reliability를 오히려 떨어뜨릴 수 있습니다.
GREEN은 half-open을 단순 stable-demotion으로만 표현하지 말고, cooldown 후 bounded single probe lease를 실제로 허용하는 쪽이 맞습니다. 동시 요청에서는 _circuit_lock 아래 한 요청만 probe를 점유하고 나머지는 healthy member로 보내며, probe 성공 시 즉시 closed/level reset, 실패 시 기존 exponential cooldown으로 re-open해야 합니다. 최소 acceptance는 (1) healthy secondary가 계속 성공해도 cooldown 후 A가 정확히 한 번 probe됨, (2) 16개 동시 요청에서 half-open probe가 1개를 넘지 않음, (3) probe 성공 후 원래 ranking이 복구됨, (4) probe 실패 시 retry/replay 권한은 새로 생기지 않고 기존 failure-boundary 계약을 그대로 따름, (5) default-off legacy 3/30 동작은 byte-for-behavior 수준으로 불변입니다.
현재 replay가 보여주는 saved seconds는 failure-only 편향을 이미 인정하고 있고, 이 starvation 경로를 측정하지 않으므로 그 수치만으로 recovery semantics를 GREEN 처리하면 안 됩니다. 판정은 demotion/quarantine 방향 PASS candidate / half-open liveness FAIL / concurrency acceptance missing입니다.

Current-head revalidation (56276d6530dcc5bbc458189220a79fbb3a9022b6): predecessor finding 5269612445 remains fully valid. The only intervening commit (56276d65…, docs(routing): record two-sided replay fidelity and flag-on test scope) changes docs/doctoring/observed-health-quarantine.md only; _circuit_open(), _order_by_observed_health(), _failover_candidates() and the half-open tests are unchanged. The current test still proves recovery only after steady_worker is forced down, so it does not cover a healthy-secondary liveness case.
Please preserve the original RED/GREEN acceptance on this exact head: after cooldown expiry, a recovered preferred member must receive a bounded probe even while a healthy sibling keeps succeeding, with a single-probe lease under concurrency. Until that executable RED exists and the source repairs it, the current docs sentence “half-open probe” overstates runtime behavior. Exact-head half-open liveness: FAIL; source repair still required.

Separate exact-head TRACEABILITY finding (56276d6530dcc5bbc458189220a79fbb3a9022b6): 429 semantics are internally contradictory on the current source/docs. The module comment immediately above _SLOW_HEALTH_* says “429 and 413 never reach the health ledger at all”, and the runbook table says “413 and passthrough 429 never reach the ledger, the same as before”; later in the same runbook/PR body you correctly record that served _invoke 429 is charged as a fast breaker failure (144 replay occurrences) while passthrough 429 is excluded. Because classify_health_failure() itself would classify an HTTP 429 as fast, the admission behavior is call-site-dependent, not a global ‘never’ invariant.
Please make the code comment and the primary contract table code-current on this exact lane: state explicitly that 413 is excluded, passthrough 429 is excluded, and _invoke 429 remains a pre-existing charged-fast inconsistency pending an owner decision. Add/retain an executable two-path regression so a future refactor cannot silently collapse the distinction. This does not require changing the 429 policy in this PR; it requires the documented invariant to match the behavior. TRACEABILITY/comment contract: FAIL until currentized.

건강 분류에는 정규화된 classified를 전달하십시오.
classify_provider_failure는 socket.gaierror가 직접 발생하거나 __cause__에 포함된 경우 provider_connection_error로 정규화합니다. 그러나 현재 코드는 원본 exc를 classify_health_failure에 전달합니다. exc가 RuntimeError처럼 원인을 감싼 예외이면 classify_health_failure는 이를 fast로 분류합니다. 그 결과 느린 전송 실패에 slow_failure_weight와 slow_failure_cooldown_seconds가 적용되지 않을 수 있습니다.

circuit_opened 경고 로그의 필드명이 실제 값과 일치하지 않습니다.
circuit_opened WARNING 로그는 필드명을 reset_seconds로 표시합니다. 실제로 전달되는 값은 cooldown입니다. cooldown은 _circuit_cooldown()의 반환값으로, slow_failure_cooldown_seconds, 레벨에 따른 지수 백오프, circuit_max_cooldown_seconds 상한(최대 3600초)을 반영합니다. 고정된 circuit_reset_seconds(30초)와 다를 수 있습니다.
바로 아래 circuit_half_open INFO 로그는 동일한 값을 cooldown_seconds로 정확히 표시합니다. 두 로그의 필드명이 일치하지 않습니다.
운영자가 이 로그를 보고 실제 쿨다운 시간을 잘못 추정할 위험이 있습니다. 필드명을 cooldown_seconds로 바꾸십시오.

| | Cooldown | A trip that involved a slow failure lasts `slow_failure_cooldown_seconds` (360 s, longer than the longest observed slow failure of 302.3 s). A trip from fast failures only uses `circuit_reset_seconds` (30 s). Each half-open failure doubles the cooldown, capped at `circuit_max_cooldown_seconds` (3600 s). Any success resets the escalation level. Exclusion is never permanent. | | ||
| | Half-open / recovery | When the cooldown expires, the member becomes eligible again but stays demoted, so it is probed only after healthy members. A success clears the state and logs `circuit_recovered`. A failure re-opens the breaker immediately with the escalated cooldown. | | ||
| | Never empty | If every eligible member is open, `_failover_candidates` returns all of them, least-recently-failed first, and logs WARNING `circuit_all_open_fallback candidate_count=N selected_agent_id=... request_id=...`. With the flag off, the legacy ranked order is kept and only the log line is added. The embedding path's explicit 503 when all members are open (`_capability_agents`) is unchanged. However, the flag-on failure-rate and half-open triggers apply to every `_record_failure` caller, including `_record_embedding_failure`, `_record_race_attempt` and synthesis repair. | | ||
| | Metrics | WARNING `circuit_opened ... reset_seconds=<cooldown> failure_class=... trigger=consecutive|failure_rate|half_open_failure request_id=...`; INFO `circuit_half_open`, `circuit_recovered`; DEBUG `circuit_failure ... failure_class=...`. `circuit_health_snapshot()` holds bounded per-member fields: state, model, provider, counts, class, cooldown, remaining, window rate and open count. It is exposed at `admin_state()["routing_evidence"]["health"]`; `test_measured_routing_evidence` pins the key set. No prompt text or provider body text is included. | |

preflight 429만 health evidence에서 제외하세요.
include_preflight=True이면 request_id == "-"인 429 실패가 recorded 값과 관계없이 _record_failure()에 도달합니다. 이 동작은 preflight 전용 replay 결과에 운영 정책과 다른 quarantine evidence를 추가할 수 있습니다.
_NEVER_HEALTH에 429를 전역으로 추가하면 served _invoke 429도 제외됩니다. 운영 문서는 served 429를 기록하고 passthrough 429만 제외합니다. 따라서 preflight에만 적용되는 조건으로 수정한 뒤 docs/doctoring/observed-health-quarantine-replay-preflight-whatif.json을 다시 생성하세요.

로그 포맷은 ProviderUpstreamError와 숫자 provider_status를 함께 파싱합니다. 그러나 _synthetic_failure()는 이 레코드를 RuntimeError로 변환하므로 replay 분류기가 fast를 반환합니다. 운영 분류기는 ProviderUpstreamError.provider_status가 408, 502, 504일 때 slow_transport를 반환합니다. 503은 운영에서도 fast이므로 해당 예시는 502 또는 504로 바꿔야 합니다.
HTTPError가 아니라 ProviderUpstreamError를 생성해야 합니다. 변경 후 다음 두 JSON 산출물을 다시 생성하세요.

…TP e2e HTTP end-to-end contracts (route, conduct, stream, structured proxy_completion) for demotion, half-open recovery/doubling and the all-open fallback. RED showed conduct and the structured proxy path still sent the model-judge call, and auto-mode triage its single call, to a demoted member: both pick the first ranked agent outside _failover_candidates. With observed_health_quarantine on they now skip open members and try demoted ones last; flag off is unchanged.

- One deployable switch: KV setting CONTEXTUAL_ORCHESTRATOR_OBSERVED_HEALTH_QUARANTINE, read once at TaskOrchestrator construction (explicit argument wins; unset = off; invalid value fails construction). register_review_credentials copies it from bootstrap env like the gateway token, so the .github launcher needs only a pin bump and one env value. Startup INFO line and admin_state routing_evidence.health_policy make it auditable. - classify_health_failure treats provider_outcome_unknown (ModelClient's wrapping of a dropped chat connection) and model_timeout as slow; the sidecar-shaped measurement exposed the misclassification. - scripts/measure_health_quarantine_sidecar.py: launcher-shaped synthetic measurement (fake provider at _open_provider, no egress). - tests/test_rate_limit_breaker_asymmetry.py pins that _invoke charges a provider 429 to the breaker while passthrough does not (unchanged); replay gains --exclude-429 and deployed 429-in-streak counts. - Runbook: e2e RED/GREEN, measurement, activation handoff, 429 analysis; 360 s cooldown stated as an experimental candidate. Default stays off. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012ABB9sb4szFEteww67UYZy

_invoke and stream_route charged a provider 429 to the circuit breaker (and the observed-health ledger) while the passthrough loop skipped it. A 429 is quota capacity, not member health. Both paths now share _charges_breaker, mirroring passthrough skip_breaker: a 429 records only the quota cooldown (stream_route now records one; it recorded none), and a 503 still charges the breaker. Model-group stability observation is unchanged. The pinning regression runs one fixture through route, stream and passthrough. RED at b073b16: route charged failures=1.0 and stream recorded no cooldown. Replay defaults now exclude 429 as the code does; --include-429/--legacy-like reproduce the deployed pin. The synthetic sidecar output is labelled SYNTHETIC. The feature default stays off, and the 360 s cooldown remains an experimental candidate.

… measurement Semgrep flagged dynamic-urllib-use-detected in the synthetic sidecar measurement script.

The measurement export joins only "?" placeholders into the IN clause and binds every request id, so it is not SQL injection. The Semgrep gate on this head reported both statements (the rule also matches main at the same code when run alone); suppress inline with the rule id and reason, as the existing rename/drop statements do.

요약
실제 서비스 요청 결과를 보고, 후보를 고르기 전에 멤버를 뒤로 미루거나 격리하는 circuit breaker를 추가합니다. 연산자가 켜야 동작하는 opt-in이며 기본값은 꺼져 있습니다.
TaskOrchestrator(observed_health_quarantine=False)를 추가했습니다. 기본값인 꺼짐 상태에서는 기존 3/30 breaker와 동작이 같습니다. 달라지는 것은 로그 필드,circuit_all_open_fallback로그 한 줄,admin_state()["routing_evidence"]["health"]스냅샷뿐입니다.기본값을 끈 이유
docs/product-technical-gap-baseline.md의 2026-09-07 no-heuristics boundary가 "3/30을 저장소가 정한 다른 값으로 바꾸지 말 것"을 요구합니다. 그래서 메커니즘만 넣고 켤지는 owner가 정하도록 했습니다. 같은 문서에 이 결정을 가리키는 amendment를 추가했습니다.RED / GREEN
origin/main5665b0a): 테스트 수집 단계에서ImportError가 납니다. import를 빼고 돌린 behavioral RED는 9개 모두 실패했습니다. 핵심은 요청 N+1이 방금 slow 실패한 멤버를 여전히 먼저 시도한다는 점입니다:['slow_worker','steady_worker'] != ['steady_worker','slow_worker'].tests/test_observed_health_quarantine.py(10개)와tests/test_measured_routing_evidence.py를-W error로 돌려 43 passed입니다.pytest tests를 base와 head에서 비교했습니다.routing_evidence키 집합을 고정한 테스트 하나뿐이고,health키를 추가하도록 갱신했습니다.test_invoke_preserves_final_classified_failure_across_candidates는 base에서도 4번 중 1번 실패하는 wall-clock flake입니다.-W error로 돌리면 base와 head 모두 깨끗하지 않습니다. 기존 ResourceWarning spillover(fix(transport): preserve errors while closing stream resources #1140 소관) 때문입니다.Replay
Noema sidecar 로그 101개를 같은 breaker 코드로 재생했습니다(
scripts/replay_health_quarantine.py, 원본 artifact는 커밋하지 않았습니다). 기능을 끈 기준선(--legacy-like)은 skip 0으로 배포된 breaker를 그대로 재현합니다.docs/doctoring/observed-health-quarantine.md에 적었습니다.Owner 결정 사항
_invoke경로에서 429를 breaker 실패로 세는 기존 동작. passthrough 경로는 429를 세지 않아 서로 맞지 않습니다. 이번 PR에서는 바꾸지 않았습니다.🤖 Generated with Claude Code
