Description
A fault live from process start currently leaves faulted span-metric rows flat until a healthy observation exists, hiding the causal effect during cold start.
Acceptance Criteria
- #1 Causally bound span-metric rows show a fault from process start using the declared healthy reference
- #2 A subsequently learned healthy reference replaces the fallback without changing healthy output
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/
Implementation Plan
Use the accepted restored engine/timestamp candidate as baseline; reproduce a fault live from first tick, derive a declared healthy reference for causal span-metric rows until real healthy observations exist, preserve unaffected rows and learned-reference behavior, and return only the task delta.
Implementation Notes
Owner closeout: Accepted healthy-reference candidate unlanded. Resume causal-stack composition; preserve missing-own-timing limitation and learned-reference precedence.
Loop60 closeout: Accepted task-separated candidate is retained in the repaired fe995479 causal stack, not published. Composed app race still exceeds the unchanged600-second budget, including after exact optimization foundation; plain/component success is not full-gate acceptance. Resume after owner-authorized evaluator resolution, current-main composition, final generation/review/full gate and actual inventory proof. No timeout/assertion/population weakening or unchanged green sampling.
Final loop closeout: retained unlanded causal candidateaf34 has native/component review and final CodeRabbit passes, but the exact integrated full gate fails app-race600.139s. No candidate source was pushed or deployed. Preserve task-specific earlier evidence/limits; resume only after the aggregate owner stop and relevant dependency/owner decisions are resolved, with no timeout/assertion/case/isolation reduction or unchanged full-gate retry.
