Description
A collector heartbeat (last success timestamp) needs a value equal to the emission time.
Acceptance Criteria
- #1 A gauge value kind yields the tick timestamp in seconds
- #2 Deterministic under a fixed clock in -once -dump
Definition of Done
- #1 just check (fmt-check, lint, gen-check, env-check, docs-check, test, race, hygiene, ui-check, compose-check, helm-test, lab-check, signal-fidelity)
- #2 just gen (only if a blueprint field, construct/workload config struct, or a skill under plugins/synthkit/skills/ changed)
- #3 just dump — inventory diffed against signals/
