Replaces lookup_pricing(raw_model_id) + normalize_for_pricing + 17 prefix rules
with an exact (billing-authority domain, billable-model-string) lookup. Billing
authority is a distinct namespace from the runtime transport Provider enum.
Match is exact: no case normalization, no prefix matching, no inference.
Manifest (scripts/model-capabilities.json):
- Removed pricing_rules (17 prefix-match rules), pricing_exact_records (3 records)
- Added flat pricing_records list of 20 exact records, each with authority + model +
usd_per_mtok (input/output/cache_read/cache_write) + _source provenance
- Authorities: api.anthropic.com, api.openai.com — registered bare-host tokens per
D2'/NIP-AM; not transport Provider enum values
- Semantics: current list prices (ccusage-aligned); cache_write scoped to ephemeral;
other classes unknown
Generator (scripts/generate-model-capabilities.mjs):
- Removed all old pricing machinery (pricingNormalize, normalizeVersionSeparators,
pricingRules, pricingExactRecords, resolvePricing, all TS rule-resolver emission)
- Strict pricing-record validation: registered authority (closed set: api.anthropic.com,
api.openai.com, openrouter.ai); nonempty verbatim model; no control/NUL/quote/backslash
in key fields; finite nonnegative input/output; both cache_read and cache_write required
(absent member is hard error; use null for unpublished); _source provenance required;
duplicate detection on exact emitted identities
- byAuthority grouping uses exact record values — no toLowerCase() anywhere in
pricing generation path
- REGISTERED_AUTHORITIES set; hasUnsafeKeyChars() guard
- TS PRICING_TABLE: key is ${authority}\0${model} (exact strings, no transforms)
- lookupModelPricing(authority, model) performs exact Map lookup (no normalization)
- modelPricing.ts is standalone (no import from modelCapabilities)
Generated artifacts:
- generated_model_capabilities.rs: lookup_pricing(authority: &str, model: &str)
performs exact match — no to_ascii_lowercase() calls, no fallback
- modelPricing.ts: exact PRICING_TABLE + lookupModelPricing(authority, model)
CI (.github/workflows/ci.yml):
- Replaced two-step "regenerate + git diff" check with a single
node scripts/generate-model-capabilities.mjs --check step, which validates
all three generated artifacts (Rust capabilities, TS capabilities, TS pricing)
and exits 1 if any are stale. Self-maintains if a fourth artifact is added.
Tests (generated_model_capabilities_tests.rs, 23 pricing tests):
- Anthropic models with correct rates (claude-fable-5, claude-opus-5, claude-sonnet-5,
claude-opus-4-8, claude-sonnet-4-6, claude-haiku-4-5)
- OpenAI models incl. gpt-5.6-luna different tier, gpt-5.5 null cache_write, gpt-5-pro
null cache fields
- Null guards: unknown authority, custom base URL, unknown model, empty authority,
empty model, both empty, wrong authority for known model
- Exact-match guards: uppercase authority -> None, mixed-case authority -> None,
mixed-case model -> None (no case folding)
- Databricks guards: workspace URL authority -> None, 'databricks' authority -> None
Manifest validator tests (scripts/test-manifest-validator.mjs, 45 tests total):
- 21 new pricing-record mutation tests covering: missing authority, unregistered/path-
bearing/scheme authority, empty model, unsafe chars (double-quote, backslash, NUL,
control), missing output, negative rates, invalid cache rate, deleted cache_read,
deleted cache_write, missing/empty provenance, duplicate records, uppercase authority
