filelists

name	filelists
description	Filelist rules - EVERY module MUST have a .f and MUST be registered in bin/filelists.toml. Components own their compile closure, consumers -f include, never hand-list another area's sources. Use when adding ANY new RTL module, test, or .f file.

filelists

READ FIRST: vault/handbook/INDEX.md (the handbook is the repo's memory; this skill is the signpost). Canonical: vault/handbook/design/filelists.md.

A new module lands with its filelist IN THE SAME COMMIT, and its area must appear in bin/filelists.toml. A module with no .f has no consumers and is indistinguishable from dead code. Consumers -f include; never hand-list another area's sources.

Check before you commit: python3 bin/filelist_registry.py --check (also --audit / --find MODULE / --resolve F / --list). Note that --check prints PASS when declared - covered - exempt is empty - read all three numbers, not the PASS. [exempt] in the registry is a debt ledger with a stated reason, not a way to land a module without a filelist.

The handbook root is vault/handbook/INDEX.md - design/, dv/, fpga/, authoring/ areas, atomic notes, wikilinked. When you learn a durable lesson in this domain, ADD IT TO THE HANDBOOK NOTE, not to this skill.
