FAIL 1: Cron cadence was */10 * * * * (every 10 min) but the real crontab
on CT 100 is 35 2,6,10,14,18,22 * * * (every 4 hours at :35). Fixed in
frontmatter, body, and Continuity section. Added 4-hour rationale note.
FAIL 2: Added gateway log health to the list of checks (frontmatter +
Strategies section). Added note that script may perform additional
diagnostics beyond the seven contract checks.
The consolidated agent health check contract (wraps scripts/agent-health-check.py v4).
Created during earlier work but never committed — was a stray untracked file in
the execution clone, making the home look dirty to the fleet update path.
