Sync ZGPU_PRICING with the published model catalog, and guard it against drift

[amaan-ai20]

Summary

The ask was to add models missing from the CLI. I checked, and no model is missing — so this PR fixes what was actually wrong instead.

All 14 models in the model catalog already have a ZGPU_PRICING entry and are reachable from a command, and CHAT_MODELS already covers all six text-generation models the catalog exposes for chat. Verified three independent ways: a set-diff of the catalog table against ZGPU_PRICING (empty in the docs→CLI direction), the docs/text-generation model list, and both OpenAPI enums in zerogpu.openapi.json.

The gap was not coverage, it was a price. gpt-oss-120b was repriced to $0.15 / $0.60 per 1M (docs commits c316853 "fixed pricing discrepancy" and eff3ac4 "increased price for gpt-oss"); the CLI still carried {0.03, 0.10}.

That one is worth stating plainly: savings are reported as baseline cost − ZeroGPU cost, so understating the ZeroGPU rate 5× on input and 6× on output made every gpt-oss-120b call report more saved than was actually saved. It is the one number in this table a user is asked to trust.

The deeper defect is that nothing tied this table to the catalog, so a docs reprice could — and did — sit unnoticed indefinitely. That's the part this PR is really for.

Changes

• src/lib/savings.ts — correct gpt-oss-120b to { in: 0.15, out: 0.6 }; export ZGPU_PRICING so it can be pinned by a test.
• tests/savings.test.ts — transcribe the full published catalog and assert against it in both directions: every catalog model carries the published rate, and nothing is priced that the catalog does not list (catching a retired model or a typo'd id). Drift now fails CI instead of quietly misreporting savings.

ZGPU_FALLBACK is unchanged — glm-5.2 at {1.10, 3.50} is still the priciest published rate, and the existing "never overstates savings" invariant still holds with gpt-oss-120b at its true price.

Not added: zlm-v1-moderation-edge. It's referenced by integrations/claude-skill.mdx but is absent from the model catalog, both OpenAPI enums, and any model page — no published price or endpoint contract to implement against, so adding it would mean inventing both. Flagging rather than guessing.

Verification

Beyond the suite passing, I confirmed the new guard isn't vacuous by mutating the source and watching it fail:

Mutation	Result
Restore the stale {0.03, 0.10}	❌ fails — gpt-oss-120b: ZGPU_PRICING disagrees with the published catalog
Add an unlisted ghost-model-v9	❌ fails — + "ghost-model-v9"
Neither (as committed)	✅ 40 passed

Checklist

• npm run lint passes
• npm test passes (40 passed, up from 38)
• npm run build succeeds
• Documentation updated (if user-facing behavior changed) — n/a: no README/docs/ change needed, prices are not quoted outside savings.ts (verified by grep). No model coverage changed, so the chat model tables are still accurate.

Poem

A rabbit checked the pricing chart,
With careful paws and coding art.
The models match, the rates align,
Each catalog entry stands in line.
Hop, hop—tests keep the table fine!
