OmniRoute/tests/unit/providers-constants-split.test.ts

// Characterization of the providers.ts catalog split (god-file decomposition): the host became a
// barrel that re-exports 10 data catalogs now living under constants/providers/*, and APIKEY is
// merged from 6 semantic family files (apikey/<family>.ts). Locks: the public surface (every catalog
// + helpers still exported), the spread-merge integrity (198 APIKEY entries, no loss/dup), and that
// load-time Zod validation still runs. Pure-data move → behavior must be identical.
// Count was 171 before obsolete provider removals (PR #6675: glhf/kluster/cablyai/inclusionai etc.,
// 171->167) plus #6126 (ClinePass dual-auth): the API-key-only APIKEY_PROVIDERS_GATEWAYS entry was
// removed as a duplicate now that clinepass is OAuth-primary (OAUTH_PROVIDERS.clinepass) with its
// BYOK path admitted through the DUAL_AUTH_APIKEY_PROVIDER_IDS gate instead (167->166), then the
// OpenVecta inference-gateway addition brought it back to 167, then #7246 (Chenzk API gateway)
// brought it to 168, then more additions brought it to 172, then #6650 (g4f.space no-key gateway:
// 5 new sub-path entries — g4f-groq/g4f-gemini/g4f-pollinations/g4f-ollama/g4f-nvidia) brought it
// to 177, then 2 more provider additions in the v3.8.49 cycle brought it to 179, the free-catalog
// expansion (#7840, navy) to 180, the Alibaba/Qwen Cloud regional additions (#7882) to 182, and
// #7887 (5 free-tier providers: ainative/aion/sealion/routeway/nara) to 187, then #8077 (clova-studio/
// internlm/ant-ling, all regional) to 190, then #8161 (sarvam/writer/plamo — writer in frontier-labs,
// sarvam+plamo in regional) to 193, then #8170 (inception/typhoon — inception in frontier-labs,
// typhoon in regional) to 195, then Firecrawl dual search+fetch under SEARCH_PROVIDERS.firecrawl
// (removed specialty-media duplicate) to 194, #8861 (Xiaomi MiMo Token Plan, regional) to 195, and
// the Cheaper Inference gateway (OSS-sponsor reseller, gateways family) to 198 (UnoRouter #9009),
// then later additions to 199; retiring GitHub Models brings it to 198.
// The v3.8.50 free-tier gateway waves (#9631 registry cycle, waves 2-5, #9210 phase 3) grew the
// gateways family to 228 measured on the tip; Puter retired (#10210) and chatanywhere restored
// (base-reds round 3, #9985) are both included in that measurement; Cursor API (specialty-media,
// #10729) brings it to 229; Token Kiosk (gateways, #10722) — merged in the same
// merge-train batch — independently bumped the gateways family too, landing at 231; Freebuff
// (gateways, #10531) brings it to 232. #8864 moves uncloseai (gateways family) into
// NOAUTH_PROVIDERS, dropping the APIKEY_PROVIDERS count to 231. Logfare (gateways, #10987) brings it back to 232.
// #11176 removes hackclub (gateways family), landing at 231.
// The v3.8.50 back-merge (f95b03d) adds Synthetic (specialty-media) and
// Kilo Gateway (gateways); #11434 adds volcengine-agent-plan and
// volcengine-coding-plan (regional family) — both land at 233.
// release/v3.8.51 adds Opper (gateways, #11629) and 1min.ai (gateways, #11631) — lands at 235;
// Perplexity Agent API (#12103) makes it 236;
// UC Direct (#11513, uncensored.com metered Developer API) adds one frontier-labs entry — 237;
// SeekAi (#11786, QuantumNous New-API gateway) adds one gateways entry — 238.
// GreenPT (#13024, 2b9e7fb3e) and EURouter (#13025, 22473dee5) each add one gateways entry — 240.
