What

Tests-only PR that closes a coverage gap on workspace-server/internal/handlers/offered_models.go (CTO 2026-06-11 model-discovery endpoint, wired at GET /admin/llm/offered-models). The single existing test TestListOfferedModels_ClaudeCode (in model_registry_validation_2608_test.go) covers the happy path on ?runtime=claude-code and verifies two representative model entries. This PR adds a focused test file pinning every other branch of ListOfferedModels.

Refs #2151 (handler real-infra coverage series — smallest first; the unit-test surface is a strictly smaller increment than the chunk-2/7 real-PG integration work in #2171, and this endpoint is wired in internal/router/router.go:215 as a production surface, not a mock-only one).

Branches pinned

1. TestListOfferedModels_DefaultRuntime — empty / missing ?runtime query defaults to "claude-code"; resolved runtime is echoed in the response.
2. TestListOfferedModels_UnknownRuntime — ?runtime=does-not-exist returns 404 with {"error":"unknown runtime","runtime":"<raw>"} body.
3. TestListOfferedModels_RegistryLoadError — providerRegistry returning an error surfaces as 503 with "provider registry unavailable" body (uses the existing package-level providerRegistry swap seam from llm_billing_mode.go:61, restored via t.Cleanup).
4. TestListOfferedModels_SortOrder — manifest declares zulu/alpha/mike; response must be alphabetic-sorted (the existing test does not pin order, only membership of two entries).
5. TestListOfferedModels_BYOKAuthEnv — platform entries must omit auth_env entirely (omitempty); BYOK entries must surface the BYOK env name. Both PlatformBilled flag and Provider name are asserted per model.
6. TestListOfferedModels_AmbiguousModelSkipped — fixture triggers DeriveProvider's fail-closed ambiguity branch (model id matches two prefixes, not in any exact-list, no auth context); the ambiguous id must be dropped from the response, sibling unambiguous ids must survive.

Why a hand-built manifest, not the embedded providers.yaml

workspace_provision_derive_test.go already establishes the pattern: build a small *providers.Manifest in-test so the assertions are deterministic and do not churn when the embedded registry evolves. The fixture covers the same shapes DeriveProvider exercises end-to-end (native-arm, exact-list, prefix-match, auth-env disambiguation) without depending on the production YAML.

The broader go test ./internal/handlers/ run has pre-existing sqlmock-mismatch failures in pending_uploads / workspace_create / delegation test families (visible on main with this branch reverted — these are the same class #2171 verify-on-main analysis identified as out-of-scope for the chunk-2 PR). They are NOT caused by this PR; the PR only adds a new file.

Files changed

• workspace-server/internal/handlers/offered_models_test.go (new file, 374 lines) — 6 new test functions + 2 helpers (offeredModelsTestManifest, withSwappedProviderRegistry, callListOfferedModels).

No production code, no schema, no migration, no backwards-compat shim. Strictly tests-only.

test(offered-models): cover ListOfferedModels branches (core#2608) ... 87a6d50754

offered_models.go is the SSOT model-discovery endpoint (CTO 2026-06-11)
wired at GET /admin/llm/offered-models. The single existing test
(TestListOfferedModels_ClaudeCode in model_registry_validation_2608_test.go)
covers the happy path on ?runtime=claude-code and verifies two
representative model entries. Multiple branches of the function have
no pinned coverage:

- Empty / missing ?runtime query → defaults to claude-code
- Unknown runtime → 404 with structured "unknown runtime" body
- providerRegistry load error → 503
- Model list is emitted in alphabetic order regardless of
  manifest-declared order
- Models that DeriveProvider cannot resolve (ambiguous prefix
  with no auth context) are silently dropped
- Non-platform (BYOK) providers surface their auth_env; the
  platform provider omits auth_env entirely (omitempty)
- Response top-level 'runtime' field is the resolved (defaulted)
  runtime, not the raw query string

Tests use a hand-built providers.Manifest fixture (same shape as
workspace_provision_derive_test.go) so they are deterministic and
do not depend on the embedded providers.yaml evolving. The
providerRegistry is swapped via the existing package-level variable
seam (llm_billing_mode.go:61) — restored via t.Cleanup.

Refs #2151 (handler real-infra coverage series, smallest first). No
production code changes. test-only.

Local validation:
- go test -tags=integration -run TestListOfferedModels_ -v ./internal/handlers/ — PASS (7/7, 0.023s)
- go vet -tags=integration ./internal/handlers/ — clean
- go build ./internal/handlers/ — clean
- Pre-existing TestListOfferedModels_ClaudeCode, TestCreate_BYOKModelNoCredential_422, TestCreate_PlatformSlashModel_NoQueries all still pass.

REQUEST_CHANGES on head 87a6d507.

Blocking test-quality finding: TestListOfferedModels_AmbiguousModelSkipped does not exercise the branch it claims to cover.

The handler does:

1. models, err := m.ModelsForRuntime(runtime)
2. for _, id := range models { p, dErr := m.DeriveProvider(runtime, id, nil); if dErr != nil { continue } }

ModelsForRuntime only returns exact model ids listed in the runtime's native provider refs. In this test, shared-gpt-4o is not present in any ref.Models list, so it is never included in models and DeriveProvider is never called for it. The assertion that shared-gpt-4o is absent would pass even if the handler's dErr continue branch were deleted entirely, because the model never entered the loop. That makes the regression test tautological and leaves the claimed branch unpinned.

Please adjust the fixture so an id returned by ModelsForRuntime actually causes DeriveProvider to return an error. One viable shape is a hand-built manifest where the runtime's ModelsForRuntime includes the model through a ref whose provider is not in the provider catalog, while other native refs/providers make the same model prefix ambiguous, so the loop sees the id and DeriveProvider errors. Then assert a sibling valid model survives and the erroring listed model is dropped.

Other added tests look directionally reasonable, but this PR's stated goal is branch coverage for ListOfferedModels, and this branch is currently not covered.

test(offered-models): fix tautological AmbiguousModelSkipped test (CR2 #11570)

test(offered-models): fix tautological AmbiguousModelSkipped test (CR2 #11570) ... 33f3374070

CR2 #11570 (REQUEST_CHANGES, blocking): the prior
TestListOfferedModels_AmbiguousModelSkipped fixture put
'shared-gpt-4o' in NO provider's ref.Models list, so
ModelsForRuntime() never returned it and the handler never entered
the loop for it — the 'dErr != nil { continue }' branch was
uncovered. The test would pass even if the branch were deleted.

New fixture recipe: a runtime ref whose Name points to a provider
that is NOT in the provider catalog. ModelsForRuntime() does NOT
validate ref.Name against the catalog at runtime (that's a
parseManifest load-time check, not a runtime invariant), so it
returns the ghost-listed model. The handler calls
DeriveProvider(runtime, id, nil); step 3 cannot resolve the
ghost-ref Name to any provider, so the model falls through to
step 4; no other provider's ModelPrefixMatch regex matches; step 6
errors. The handler's 'continue' swallows the error and drops the
model. The sibling real-co-listed model survives via step 3.

Sister test (the existing TestListOfferedModels_BYOKAuthEnv) is
unaffected; the other 5 tests in this file are unaffected.

Load-bearing property: deleting 'if dErr != nil { continue }'
from offered_models.go causes 'ghost-drops' to appear in the
response (with Provider=''), which the assertion catches. The test
is no longer tautological.

Local validation:
- go test -tags=integration -run TestListOfferedModels_ -v ./internal/handlers/ — PASS 7/7 (0.020s)
- go vet -tags=integration ./internal/handlers/ — clean
- go build ./internal/handlers/ — clean

APPROVED on head 33f33740.

Reviewed the test-only offered_models_test.go addition. The branch coverage is meaningful: default runtime checks the resolved top-level runtime + model count, unknown runtime pins the 404 body, registry load failure pins the 503 path, sort order uses intentionally unsorted fixture data, BYOK checks both populated auth_env and platform omitempty behavior, and the ambiguous/skip test now uses a ghost provider ref whose model is returned by ModelsForRuntime but cannot resolve through DeriveProvider.

The ghost-co fixture is sound for this unit level: it deliberately bypasses manifest load validation to exercise the runtime handler branch where DeriveProvider errors for a listed model. The sibling alpha-survives assertion keeps the test from passing by emptying the whole response, so the dErr { continue } path is load-bearing rather than tautological.

I could not run Go tests locally because this container lacks go, but live CI on 33f33740 has CI / Platform (Go), E2E API Smoke Test, and CI / all-required green. Remaining red statuses are governance/review ceremony.

APPROVED on head 33f33740.

Re-reviewed the #11570 fix. The ambiguous/unselectable-model test now genuinely reaches the handler's dErr != nil { continue } branch: ModelsForRuntime("split") returns both alpha-survives and ghost-drops, then DeriveProvider resolves the real catalog ref and errors on the dangling ghost-co ref because it is absent from the provider catalog and no prefix fallback matches. If the continue were removed, ghost-drops would be appended and the new assertion would fail; the test is no longer tautological.

The hand-built providers.Manifest is acceptable here: this unit is explicitly testing the runtime handler path and DeriveProvider failure behavior, not manifest load validation. The fixture bypasses parse-time validation only to create the runtime-unselectable state needed to pin the branch. The sibling-survives assertion also guards against accidentally dropping the whole response on one bad model.

Other branch tests remain scoped to the same new test file. Verified current-head CI: Platform Go, Handlers Postgres, Shellcheck, and CI / all-required are green on 33f33740. Remaining gate/review status is review ceremony, not a code/test blocker.
