closes MEDIUM/LOW from feat/agent-dna-three-layer audit:
- models.toml: cache_write_1h_per_mtok_micro added to all 11 entries
(Anthropic: 200M/600M/1000M micro = $2/$6/$10 per MTok per pricing page;
other providers: 0 placeholder)
- main.rs (kei-model-router): WAL pragma + busy_timeout errors now logged
to stderr instead of silently dropped (previously .ok() swallowed both)
- models.toml: Haiku id pin TODO documented (router still hardcodes alias)
Splits agent definition into stable provider + swappable model + role-bound
profile. Adding a new LLM API is one row in providers.toml; new model is
one row in models.toml; agent invocation picks any (provider, model) pair
through agent-profiles.toml default_model_ref.
- providers.toml: 10 providers — anthropic, openai, codex (OAuth), xai,
deepseek, google, ollama-local, mlx-local, lmstudio-local, litellm-proxy
- models.toml: 11 models with cost_*_per_mtok_micro + context_window +
verified_at + deprecated_at
- agent-profiles.toml: 18 representative profiles; manifest_path points
to the canonical .md in ~/.claude/agents/
Three-layer DNA per the new architecture:
agent-shell::<provider>:<model>:<caps>::<scope8>::<body8>-<nonce8>
This commit only adds registries — kei-model-router still hardcodes
the Claude-only Model enum. Wave 4 will rewire it to read TOML.
