The authoring/compile layer (ADR-0023): deterministic wire:key generation (lw-crc32(template)-counter, the morph anchor for keyed children in loops), <lievit:...> tag compilation into a mount declaration, and the single-file component compilation cache (reflect + parse colocated regions + cache by source staleness). Pure Java, zero Spring, zero new runtime reflection; depends only on lievit-core. Keeps the dispatcher, codec, and HTTP edge untouched.
