docs(6209): calibration stamp, after-write hook, usage seam, work log, duplicates, skill structure, tuning and rulebook routes, kind surface, prompt filter, moments, strict args, auth, lesson write path

Fourteen more test files: docstrings state the failure each guard defends
as a present-tense shape instead of the incident that found it, and issue,
milestone and rule numbers leave comments and assertion messages.
