Follow-up to the salvaged #49129 commit. The original change flipped the
shared generic-provider merge in provider_model_ids() to live-first
unconditionally, which regressed curated-first for single providers
(kimi/zai, #46309) — and the PR encoded that regression by flipping the
kimi-coding and zai test assertions to expect live-first.
Gate live-first on an explicit _LIVE_FIRST_PICKER_PROVIDERS set
({opencode-zen, opencode-go}); every other provider keeps curated-first.
Also widen the uncapped picker + live-first sets to opencode-go, which has
the same 70+ model catalog problem as opencode-zen. Restore the
kimi-coding curated-first test and rewrite the merge-order test to assert
the per-provider contract.
The generic live+curated merge (commit 630b438) seeded the merged list
from live results, demoting curated-only models below live ones. That
regressed #46309, which deliberately surfaces the newest curated model
(kimi-k2.7-code) FIRST in the native picker even when the live /models
listing lags. Restore curated-first ordering: curated entries lead (in
catalog order), live-only entries are appended for discovery. This keeps
the #46850 fix (zai glm-5.2 now appears) without the kimi regression.
Also switch the validate_requested_model curated fallback (commit
ee7b8a4) from provider_model_ids() — which triggers a second, uncached
live /models fetch with its own 8s timeout and may resolve different
credentials than the api_key/base_url just probed — to the pure-catalog
helper _model_in_provider_catalog(). Membership is checked against the
shipped catalog only, with no extra network call.
Tests: restore the curated-first assertion in
test_kimi_coding_live_catalog_does_not_hide_curated_k2_7_code; update
the new merge tests to curated-first semantics; de-circularize the
validation fallback tests to patch _PROVIDER_MODELS (the real source)
instead of mocking the function under test.
When live /v1/models responds but omits a model that exists in the
curated static catalog, validate_requested_model now accepts it with
a note instead of rejecting. This covers the /model slash-command path
(the picker path was already fixed in the parent commit).
Addresses review feedback from potatogim on #46857.
When a provider's live /v1/models endpoint returns a stale or incomplete
list (e.g. Z.AI missing glm-5.2), the generic profile-based code path
returned only the live results, silently dropping curated models.
Generalize the kimi-coding merge pattern to all providers: live entries
come first (provider's preferred order), then curated-only entries are
appended with case-insensitive dedup. This ensures models that the live
endpoint omits still appear in /model picker.
Fixes#46850
