feat(llm): config-driven provider declaration and catalog drift check#307furgalep wants to merge 1 commit into
Conversation
An llm_config.yaml alias can now declare its logical provider and model compat group. Opaque enterprise/gateway model ids resolve to no provider on their own, so without a declaration they carry no identity and replay compatibility fails closed. The declaration is the config's answer: - ModelConfig gains typed optional 'provider' and 'compat_group' fields (extra=allow passthrough unchanged); the registry schema documents them. - get_llm_client resolves a declaring alias through the contracts parser and attaches a ProviderIdentity to the client as metadata only: request parameters are untouched, and undeclared aliases behave exactly as before. - nooa.unifiedllm.declaration translates the declaration into process-lifetime compat-group registration and reasoning-capability overrides, applied lazily on first use of the alias. Declared values override the built-in catalogs; a provider that contradicts what the model string itself resolves raises rather than guessing, and a group name owned by a different provider is rejected. The declared group is authoritative for the declaring alias's opaque replay key, so other groups claiming the same model cannot silently win. - scripts/refresh_model_id_corpora.py rebuilds the openrouter and nvidia_gateway corpus sections from the live catalogs, prints the resolution/misattribution summary, and supports --check to exit 1 on drift without writing. Offline it exits non-zero with a clear message and never truncates the fixture; the provenance comment is excluded from drift so its fetch date does not trip the check.

♻️ Proposed docstring clarification
``capabilities`` is an optional registry mapping shaped like :class:`ReasoningCapabilities` (``capture_kinds``, ``effort_map``, ``replay_field``, ...). It is validated, never trusted: an invalid declaration is warned about and dropped, because a wrong *capability* profile degrades reasoning handling without breaking the request path — unlike a wrong *identity*, which must fail loudly. + + Scope: the override is registered per *provider*, not per alias, and it + replaces the profile wholesale.

Reject an empty NVIDIA catalog before replacing the fixture section.

🌐 Web query:
site:github.com/python/cpython 3.12 Lib/urllib/request.py HTTPRedirectHandler redirect_request Authorization
💡 Result:
In Python 3.12, the urllib.request.HTTPRedirectHandler.redirect_request method is responsible for handling HTTP redirections [1][2]. Historically, a security concern existed where sensitive headers, such as Authorization, were inadvertently leaked across cross-origin redirects [3][4][5]. To address this, Python's implementation includes logic to prevent such leaks [5]. Specifically, when a redirect occurs, the library attempts to filter out sensitive information. If you examine the source code for Lib/urllib/request.py in version 3.12, the redirect_request method creates a new Request object for the redirected URL [1]. When constructing the headers for this new request, it filters the original request's headers to ensure that sensitive headers—including Authorization—are not improperly forwarded to a different origin [1][3][5]. In summary, for Python 3.12: - The redirect_request method is designed to mitigate the risk of leaking the Authorization header during cross-origin redirects [3][5]. - This behavior aligns with security best practices to prevent credentials from being sent to unintended third-party servers [3][5]. - Note that there is a known, long-standing inconsistency between the parameter naming in the official documentation (which often uses hdrs) and the actual implementation in the source code (which uses headers) [6].

Reject declarations that are empty after strip().
declared_provider and declared_group become "" when the YAML value is "" or whitespace only. "" is falsy, so the code takes the undeclared path instead of failing closed.

Include the endpoint in declared replay identities
get_llm_client passes api_base to apply_alias_declaration, but the function omits endpoint_id and account_scope when deriving opaque_replay_key. The derivation contract includes both fields. Different gateways can therefore receive the same replay key when their provider, API style, and compatibility group match. Derive a stable endpoint fingerprint from api_base and pass it to the identity, or document that declared identities are endpoint-agnostic.

Resolve the alias declaration before constructing the client.
CompletionClient and ResponsesClient eagerly create both HTTPX clients. If apply_alias_declaration then raises ValueError, get_llm_client can leave those transports unclosed. close() releases only the sync transport; aclose() is required for the async transport. Resolve and store the ProviderIdentity before construction, then assign it to the client after construction.

Assert the capability override precisely.
The disjunction hides the real check. "banana" is declared as an effort_map value, never as a capture kind, so "banana" in got.capture_kinds is always false. Only the right operand tests anything.
The form is also hard to diagnose. If the override does not register, got.effort_map["medium"] raises KeyError instead of producing an assertion message. Assert the declared fields directly.

Point the offline-failure test at a temporary fixture copy.
This test reads the committed tests/unifiedllm/fixtures/model_id_corpora.json and asserts it is unchanged. It does not monkeypatch script.FIXTURE, so the script under test operates on the real repository file.
The assertion holds only while the failure path aborts before any write. If that path regresses, the test overwrites a tracked fixture in the developer's working tree instead of reporting a failure. The sibling tests at Lines 585-587 and Lines 600-602 already copy the fixture to tmp_path and patch script.FIXTURE. Apply the same isolation here.

Summary
Let an
llm_config.yamlalias declare the two things an opaque enterprise/gateway model id cannot prove on its own: its logical provider and its model compat group.Why
Model ids reach the registry as routing strings, and some resolve to no provider at all — enterprise gateways rename models (
acme-internal-model-v2that is really a wrapped GPT), so without a declaration the id carries no identity and replay compatibility fails closed. The declaration is the config's answer, with no code required:What's in it
ModelConfiggains typed optionalprovider/compat_groupfields (extra="allow"passthrough unchanged); the registry schema documents them.get_llm_clientresolves a declaring alias through the identity parser and attaches aProviderIdentityto the client as metadata only — request parameters are untouched, and undeclared aliases behave exactly as before (no identity attached; consumers keep failing closed).nooa.unifiedllm.declarationtranslates the declaration into process-lifetime registrations (compat-group membership, reasoning-capability overrides) that override the built-in catalogs. Fail-closed rules: a declared provider that contradicts what the model string itself resolves raises rather than guessing; a group name owned by a different provider is rejected; the declared group is authoritative for the declaring alias's opaque replay key, so other groups claiming the same model cannot silently win; capability errors degrade with a warning (a wrong capability profile degrades handling; a wrong identity misroutes artifacts — that one fails loudly).scripts/refresh_model_id_corpora.pyrebuilds the live corpus sections (OpenRouter public catalog; NVIDIA gateway whenNVIDIA_INFERENCE_API_KEYis set) from their/v1/modelsendpoints and prints the resolution/misattribution summary.--checkexits 1 on drift without writing — a one-command catalog-drift detector. Offline it exits non-zero with a clear message and never truncates the existing fixture; the provenance comment is excluded from drift so its fetch date does not trip the check.Notes
Tests
34 new tests in
tests/unifiedllm/test_declaration.py: opaque alias with a declaration derives the group key; without, no key and no registrations; declared values override the catalog; lazy re-application on changed declarations; identity attached as metadata only (constructor kwargs recorded, no identity keys leak); refresh-script unit tests (offline non-zero exit with fixture untouched,--checkdrift exit 1,--checkgreen against the current fixture).uv run pytest -q tests/unifiedllm tests/config— 480 passed. Live drift check: OpenRouter 430 ids, resolution 0.79, misattributed 0; NVIDIA gateway 90 verifiable ids, resolution 0.91, misattributed 0. Ruff check + format clean.🤖🤖🤖
