Module Size Discipline
Use when planning tasks that touch big source files, when an edit would push a file past the module-size ceiling, when the pre-commit module-size ratchet warns or blocks, or when generating policies/module-size-baseline.txt. Operationalizes FR-25 — module-size ratchet (ceiling default 800; over-ceiling files may shrink, never grow; extraction along a responsibility seam is in-scope, not scope creep). Do NOT use for docs/markdown size (FR-23 owns docs), to force decomposition of an existing monolith (that is its own explicit ticket), or to judge split quality by regex (seam-vs-mechanical is semantic — code-review owns it).
