feat(kei-model-router): registry-driven, three-layer DNA
Removes hardcoded Claude-only Model enum. Pricing constants now read
from _blocks/registries/models.toml at startup; provider/model lookup
goes through a typed Registry returned by registry.rs.
New API surface:
- Registry::load(dir) → (providers, models, profiles)
- pick(profile_id, &Registry) → Result<(provider_id, model_id)>
- cost_micro_cents(model_id, in, out, &Registry) → Option<u64>
- next_model(model_id, &Registry) → Option<&Model> (ascending cost,
same provider, skip deprecated)
Files:
- registry_types.rs new 107 LOC (Provider/Model/Profile structs)
- registry.rs new 152 LOC (TOML load + lookups)
- pricing.rs rew 127 LOC (registry-backed, no constants)
- escalate.rs rew 181 LOC (registry-backed ladder + skip deprecated)
- select.rs rew 131 LOC
- select_kernel.rs new 74 LOC (Constructor-Pattern split)
- select_posterior.rs new 178 LOC (Constructor-Pattern split)
- posterior.rs rew 197 LOC
- calibrate.rs rew 175 LOC
- lib.rs rew 53 LOC
- main.rs rew 163 LOC (CLI updated to new API)
- Cargo.toml dep added toml 0.8
Verification (orchestrator-side, RULE 0.13 §Verify-before-commit):
- cargo check → clean
- cargo test --release → 58 passed / 0 failed / 0 ignored
- LOC limit (Constructor) → max 197 / limit 200
- largest fn cmd_select → ~27 LOC / limit 30
DNA-INDEX.md regenerated by kei-registry hook (primitive count
144 → 150 reflects the 6 new/split modules).
=== STATUS-TRUTH MARKER ===
shipped: functional
stubs: 0
cargo-check: PASS
behaviour-verified: yes
follow-up-required:
- select.rs `estimated_cost` still embeds inline cost constants
mirroring models.toml; if non-Anthropic providers need dynamic
pricing in select-time estimation, thread Registry through.
- External callers of old `cost_micro_cents(Model, ...)` signature
will break — intentional, no external callers in this workspace.
