03-history: Retain monitor event history¶

Context¶

Implementation ticket from the approved Durable CPRa plan.

What to implement¶

Daily indexed bbolt segments, 30-day event retention, replay identity, history compaction barrier and complete backup validation.

Where¶

internal/durable/history.go

Acceptance criteria¶

[ ] Retention, pagination, replay and restore tests; no retained raw check records.
[ ] Preserve existing manifests, read-only interfaces, Go 1.25 and optional driver tags.

Out of scope¶

Multiple voters, hosted operations, subscriptions, raw check history, automatic unknown-action replay, infrastructure purchases and unverified release claims.

Depends on¶

02-incidents

Technical notes¶

The approved user plan is the requirements authority. Existing source artifacts and the separate documentation checkout must be preserved. File mapping may be refined within that scope during implementation.

Definition of done¶

[ ] Implementation and acceptance checks complete.
[ ] Independent review complete.
[ ] Relevant standard checks pass.
[ ] Configuration, behavior and evidence documented.
