A provider that merely logged + any error with no corresponding rollback at all still does not count against the bound — the bound + is about discovery failures with rollback evidence, not raw error-log noise. + +Only when a single provider's credential is missing, the secret was supplied, and its classification is +exactly `transient_failure` does the job print a `::warning::` (with `providers_with_errors`, +`catalog_refresh_failure_count`, `restored_credentials`) and succeed — matching what the bootstrap +design already promises: the pool keeps serving from last-known-good/other-provider models. The +existing `catalog_model_count`/`eligible_model_count`/`selected_agent_ids` checks are unchanged and +still fail the job if the pool itself is unhealthy. + +**Four review rounds, not one.** The first cut only checked whether the missing credential's provider +appeared anywhere in `providers_with_errors`, with no auth/transient distinction and no bound on +simultaneous providers. Devin and CodeRabbit's first pass caught both gaps (fixed above). Devin's +*second* pass on that fix caught a narrower version of the same underlying problem: the original +transient bucket was `_TRANSIENT_FAILURE_ERROR_CODES | {any http_status_*}`, so a *persistent* non-auth +4xx (400, 404, …) or a successful-but-empty listing — either plausibly a permanently broken +integration, not a blip — was still being tolerated forever. Narrowed to the retryable-only set above, +plus the default-deny reframing so a future new classification value is hard-fail by default rather +than silently allowed. Devin's research-grounding finding on this entry was declined: this is a CI +reliability bugfix (isolating transient vs. permanent provider failures), not a novel algorithm or +research claim, and no other CI-only fix in this repo's history (`abb9aaa6`, `b3278df7`, `c328c1e8`, +`1bbda718`, `8abc4b45`) attaches a paper either. + +Devin's *third* pass ("Durable rollback bypasses failure verdict") found the deepest gap of the three, +in the still-standing `if not missing: return ... True ...` early return itself. `missing` is computed +as `expected_credential_names - registered_credentials`, and `registered_credentials` on the report is +filtered to names where `get_credential(name) is not None` *after* rollback has already run. On the +run-scoped/first-registration KV every test above exercises, a failed provider's rollback restores +`previous_credentials[name] = None` (nothing was registered before), so the name both leaves +`registered_credentials` and enters `restored_credentials` — the two were accidentally redundant in +every scenario the first two rounds tested. But on a KV that already durably held a still-valid value +for that name from an earlier successful run, rollback restores *that* value instead of `None`: the +credential never leaves `registered_credentials` at all, `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 built across the first two rounds silently +unreachable: a revoked or rotated credential, or several providers failing at once, would both report +`ok=True` forever. Fixed by evaluating the union of `missing` and `restored_credentials` (bridged +credential-name→provider-name through the same `provider_by_credential` map the `missing` path already +used, joined on `expected_credential_names` for defense against untrusted report input) through the +identical unconfigured/unexplained/classification/bound checks, rather than `missing` alone — a name +that shows up in `restored_credentials` for a reason the report can't tie to `providers_with_errors` +still hard-fails as an unexplained rollback, exactly like a fully-missing name would. + +Devin's *fourth* pass ("One NVIDIA outage fails sync") caught a false-positive introduced by fixing the +third-round gap: `nvidia_nim` and `nvidia_nim_sub` are two separate `provider_name` values but one +upstream outage domain — two KV credential names (`NVIDIA_NIM_API_KEY`/`NVIDIA_NIM_API_KEY_SUB`) +registered for load balancing against the same NVIDIA endpoint, per `PROVIDER_MODEL_SOURCES`'s own +comment and `model_discovery._provider_family` (already used by `select_provider_diverse_models` for +exactly this collapsing). The `affected_providers` bound counted raw `provider_name`, so a single +NVIDIA-side blip that happened to fail both keys at once counted as *two* providers degraded and +hard-failed — exactly the isolated-outage case the tolerance exists for, misread as a broad one. +Fixed by routing `affected_providers` through `_provider_family` before comparing against +`max_tolerated_missing_providers`; the per-credential unconfigured/unexplained/classification checks +are untouched (they still key off the real `provider_name`, since `providers_with_errors`/ +`provider_error_classifications` are recorded per source, not per family). + +Regression coverage in `tests/test_provider_catalog_bootstrap.py` (a genuinely retryable status — +408/429/5xx — tolerated as a warning; an HTTP 401/403 authentication failure still hard-failing; a +persistent non-auth 4xx and an unparseable response still hard-failing; two simultaneous provider +failures still hard-failing; for the third round, an authentication failure and two simultaneous +failures each reproduced end to end with the credential pre-registered so rollback restores a +durable, non-`None` prior value — `test_durable_rollback_with_auth_failure_still_hard_fails`, +`test_durable_rollback_with_two_simultaneous_failures_still_hard_fails` — plus +`test_durable_rollback_with_single_transient_failure_is_still_tolerated` confirming the fix doesn't +over-correct into hard-failing a legitimately tolerable single transient outage; and, for the

plus a genuinely distinct provider still hard-failing +(`test_nvidia_family_outage_plus_a_distinct_provider_still_hard_fails`)) and +`tests/test_provider_catalog_bootstrap_boundaries.py` (the verdict
