QA Gate (P0/P1) / Test affected app (pull_request) Has been cancelled
Prod decode was dominated by the DataImpulse proxy: ~50% of ports dead at any moment, 57% of captured tokens discarded by validation, the dead-port slot never evicted (invalidateSession only fired on 401/403, never on transport timeout), and a cold pool blocked the user inline on a multi-second capture. pcat sub-timing was p50 8.3s / p90 56s, blowing the 25s decode budget. Verified on prod: the TWS- token is NOT request-time IP-bound (0 auth 401/403 across thousands of calls; a token captured on one IP replays 200 through arbitrary fresh residential IPs). So the proxy can rotate freely. - Transport swap to Floxy residential (PCAT_PROXY_PROVIDER=floxy|dataimpulse|none). Call/validate leg = a fresh exit IP per request (max IP diversity → min per-IP ban); capture leg = a sticky session per Playwright attempt. DataImpulse + direct kept as env fallbacks. Token decoupled from the slot (proxyPort removed). - Prune 3 zero-yield JWT sites (knkauto/autodo.kz/flynestauto — 0 captures, ~80% of attempts); add PCAT_JWT_SITES env override. - Lower catalog-scrape timeout 30s→10s (env-tunable) so a slow IP aborts within budget and the retry rotates to a fresh IP. - Cold-pool fast-fail on the decode race: warm in background, let EMEX/PL24 answer instead of blocking inline; treated as a transient miss (no neg-cache). - Evict a token after N consecutive transport failures on rotating IPs (the dead-slot bug); reset on any 2xx. - PCAT circuit breaker mirroring PL24 (transient-only; cold-skip neutral; skip marks outcome.transient so a pcat-only VIN isn't negative-cached 30m). Typecheck + Biome + unit tests (categories/vehicles) green. Default flips pcat to Floxy on next deploy; instant rollback via PCAT_PROXY_PROVIDER. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
