"""explicitness_audit.py — lightweight codebase explicitness inventory.

Purpose:
- surface files that still carry "implicit"/"TODO"/"not yet implemented" style markers
- report whether key markdown docs declare basic metadata
- give the repo a repeatable first pass instead of relying on memory

This is intentionally modest: it inventories and flags. It does not pretend to
fully understand every file's semantics.
