Modules

cache_policy

The one derivation of cache_policy → response headers (R749-T1, R749-B4).

manifest

Manifest types — the single document the build emits and the proxy boots from. Mirrors packages/mesofact-runtime/src/manifest.ts. Schema spec lives in .yah/docs/architecture/mesofact.md §“Manifest schema”.

policy

Declared-vs-enforced route policy (R749-T1) — the general form of the rule crate::manifest fields keep re-learning one field at a time.

proxy

axum proxy — boot, manifest reload, Mode 1 dispatch, worker pool, and the P9 Mode 2 SSR slice (response cache + cache-key composition + session + source generations). Mode 3 dispatch is stubbed (501) — wired up in P10. See .yah/docs/architecture/mesofact.md §“IPC protocol” and §“Components”.

validate

Manifest validator — semantic rules over a parsed Manifest. Mirrors packages/mesofact-runtime/src/validate.ts. Used by the proxy on boot (refuse a malformed manifest, keep the old one live) and by the build to reject forbidden shapes before HTML hits R2.
