w32time is Stopped on provisioned endpoints, confirmed on more than one box, so w32tm returns 0x80070426 fleet-wide and there is no offset to read. It appears to be stopped by policy after provisioning. Collecting it would return null everywhere and give us an alerting signal that can never fire, which is worse than not having one: a permanently-null health check reads as no problem found.
Implemented first, then removed - collector, both parsers, the process helper, and the contract field. Kept one note in the notes file: parse the offset by label, not by first value ending in s, because w32tm prints Root Delay and Root Dispersion in the same format beforehand and a first-match parser reports network latency as clock skew. That bug was written and caught here.
Windows Update history is pinned rather than cut. The COM update searcher is slow, but the blocking concern is that some endpoints host COM server applications where driving it risks interfering with collections or the hosted application. Needs its own investigation. The Phase 4 card that depended on it is marked blocked so the two do not drift apart.
