From fd3e0178432f85aebf28ee6a5decd4d2e92210da Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 30 Aug 2026 13:12:18 +0000 Subject: [PATCH 1/7] fix(ci): tolerate an isolated provider outage in provider-catalog-sync provider-catalog-sync's embedded verification script hard-failed whenever any single provider's credential was rolled back after a discovery failure, even though bootstrap_provider_catalog_runtime already retains last-known-good models and keeps serving from the other providers by design. Every scheduled run has failed on BYTEZ_API_KEY since the schedule went live 5 days ago (44 of 46 runs) with the pool otherwise healthy. Distinguish a real configuration gap (secret never supplied) or an unexplained rollback (no providers_with_errors evidence -- could hide a real bug) from a supplied credential whose provider is named in providers_with_errors: only the former two still hard-fail; the isolated- outage case now emits a ::warning:: with the report's own evidence (providers_with_errors, catalog_refresh_failure_count, restored_credentials) and lets the job succeed. No production code changed. Documented the investigation, the live Bytez probe evidence, and the corroborating ContextualWisdomLab/.github http_status_500 signature in docs/product-technical-gap-baseline.md.

ProviderDiscoveryError.error_code already distinguishes these (http_status_401/403 vs timeout/transport_error/ other http_status_*) via model_discovery._provider_discovery_error_code; that information was computed but discarded before reaching the report. - CodeRabbit: the check could report success while multiple providers were degraded simultaneously (a broad outage, not an isolated blip), leaving scheduled sync silently serving a stale catalog. Fix: bucket each discovery failure into a small, report-safe classification (provider_error_classifications: authentication_failure | transient_failure) via a new _classify_discovery_error_code, threaded through ProviderCatalogSnapshot/ProviderCatalogBootstrapReport. Move the whole hard-fail/warn/ok decision out of inline YAML branching into a new, unit- tested evaluate_provider_credential_inventory(): still hard-fails an unconfigured secret, an unexplained rollback, an authentication failure, or more than one provider missing at once; only a single provider's transient-classified rollback, with its secret present, is tolerated as a warning. The workflow now just calls this function. New regression coverage in tests/test_provider_catalog_bootstrap.py (transient HTTP 500 tolerated; HTTP 401/403 still hard-fails; two simultaneous provider failures still hard-fail) and tests/test_provider_catalog_bootstrap_boundaries.py (the verdict function's own edge cases: fully healthy, unconfigured secret, unexplained rollback, non-string error code). 100% statement and docstring coverage on provider_catalog_bootstrap.py. Also tightened the gap-baseline doc's run-history wording (CodeRabbit) to avoid calling the 2 cancelled/skipped runs "failures".

f27a6a919e09924d84ced39a6d28603918491966 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 30 Aug 2026 13:29:32 +0000 Subject: [PATCH 4/7] fix(ci): narrow transient classification to genuinely retryable codes Address Devin's second-pass finding on PR #928: the transient bucket was any http_status_* other than 401/403, so a persistent non-auth 4xx (400, 404, ...) -- almost always a genuinely broken integration (wrong endpoint, malformed request shape, a moved/retired API) rather than a self-resolving blip -- was tolerated forever, same underlying problem as the authentication-failure gap already fixed, just for a different code range. Narrow transient_failure to only standard-retry-semantics-retryable conditions: 408, 429, 5xx, timeout, transport_error. Everything else (a persistent non-auth 4xx, invalid_response, a successful-but-empty listing, or anything unrecognized) now collapses to unknown_failure and hard-fails. evaluate_provider_credential_inventory is reframed as default-deny: it now requires the classification to be exactly transient_failure to tolerate, rather than only excluding authentication_failure -- so a future new classification value is hard-fail by default, not silently allowed. New tests: a persistent 400/404/invalid_response still hard-fails (test_persistent_client_error_is_not_excused_as_a_transient_outage); 408/429/5xx are confirmed still tolerated (test_genuinely_retryable_http_statuses_are_transient). 100% statement and docstring coverage maintained. Declined Devin's research-grounding finding on the gap-baseline doc entry: this is a CI reliability bugfix (isolating transient vs. permanent provider failures), not a novel algorithm or research claim, and no prior CI-only fix in this repo's history attaches a paper either -- noted in the doc entry.

On the run-scoped/ephemeral KV every test so far exercised, a failed provider's rollback restores None, so the credential leaves registered_credentials AND enters restored_credentials together -- the two were accidentally redundant. On a durable KV that already held a still-valid prior value for that credential, rollback restores that value instead of None: the credential never leaves registered_credentials, missing comes back empty, and the function returned healthy at the very first line -- without ever inspecting provider_error_classifications. After a scheduled sync's first successful run against the durable PostgreSQL KV, this made the entire auth-failure/persistent-4xx/multi-provider hard-fail logic silently unreachable: a revoked or rotated credential, or several providers failing at once, would both report ok=True forever. Fix: evaluate the union of `missing` and `restored_credentials` (filtered to expected_credential_names, mapped through the same provider_by_credential map) through the identical unconfigured/ unexplained/classification/bound checks, rather than `missing` alone. A name in restored_credentials with no corresponding providers_with_errors entry still hard-fails as an unexplained rollback, same as a fully-missing name would. New tests reproduce the durable-KV path end to end by pre-registering a credential before bootstrap so rollback restores a non-None prior value: test_durable_rollback_with_auth_failure_still_hard_fails, test_durable_rollback_with_two_simultaneous_failures_still_hard_fails, test_durable_rollback_with_single_transient_failure_is_still_tolerated (tests/test_provider_catalog_bootstrap.py), plus three unit-level cases directly against a report where registered_credentials is already complete (tests/test_provider_catalog_bootstrap_boundaries.py). Also fixed two stale "non-authentication discovery failure" mentions left over from the round-2 narrowing to say "transient" instead. 100% statement and docstring coverage maintained.
