Architecture

ch3 is authored inside the scriptc compilable subset: the whole package lowers statically into a native ELF via scriptc build --npm-static ch3 with zero deferred sites (100% static coverage on scriptc 0.2.8).

The full document lives in the repo: ARCHITECTURE.md.

Highlights of the subset rules the source obeys:

• | null unions only
• Plain records for route data (no function values inside records: handlers live in App._fns, nodes carry indices)
• Indexed loops, no recursion for matching (explicit frame stack)
• No slice/concat/spread on package paths
• Statement-called res.end()

One file, src/index.ts, holds the whole core: router, context, node adapter.

The generated-dispatch seam (src/gen.ts, frozen contract) allows build-time route lowering: route-contract.md.
