# ARTIFACT-STORE-WP-0003: Retention Lifecycle
|
|
|
|
## Purpose
|
|
|
|
Implement the retention engine. By the end of this workplan, every
|
|
package has a computed `expires_at`, operators can extend retention or
|
|
apply / release holds, and the system can mark expired packages as
|
|
eligible for deletion — without actually deleting bytes (GC is
|
|
WP-0006).
|
|
|
|
## Constraints
|
|
|
|
- ADR-0002 (every retention change is an event).
|
|
- `docs/ARCHITECTURE-BLUEPRINT.md` retention sections.
|
|
|
|
## Prerequisites
|
|
|
|
- WP-0001 done (`retention_classes` seeded, `retention_state` view
|
|
exists).
|
|
- WP-0002 done (HTTP surface exists to attach the new endpoints to).
|
|
|
|
## D3.1 - Default Retention Application
|
|
|
|
```task
|
|
id: ARTIFACT-STORE-WP-0003-T001
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "25531837-d2ff-4252-b0d0-31283597737f"
|
|
```
|
|
|
|
Acceptance:
|
|
|
|
- On `POST /packages`, the requested `retention_class` is validated
|
|
and the `v1.retention.default_applied` event is written with the
|
|
computed `expires_at`.
|
|
- Default durations per class are operator-configurable via a
|
|
config file (TOML); the file path is documented in `OPERATOR.md`.
|
|
- `permanent-record` packages have `expires_at = NULL` and
|
|
`eligible_for_deletion = false`.
|
|
|
|
## D3.2 - Retention Extensions
|
|
|
|
```task
|
|
id: ARTIFACT-STORE-WP-0003-T002
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "66576e53-af4c-48dc-8dc3-cf8223a821c7"
|
|
```
|
|
|
|
Acceptance:
|
|
|
|
- `POST /packages/{id}/retention/extensions` accepts
|
|
`{new_expires_at, reason}`. The new value must be strictly later
|
|
than the current; reason is mandatory.
|
|
- Each extension writes a `v1.retention.extended` event;
|
|
`retention_state.current_expires_at` updates on the same
|
|
transaction.
|
|
- A package's full extension history is recoverable from `events`.
|
|
|
|
## D3.3 - Holds (Apply And Release)
|
|
|
|
```task
|
|
id: ARTIFACT-STORE-WP-0003-T003
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "8164e448-0e90-41aa-a973-77f8f607a0b3"
|
|
```
|
|
|
|
Acceptance:
|
|
|
|
- `POST /packages/{id}/retention/holds` records a hold with a reason
|
|
and actor; emits `v1.retention.hold_applied`.
|
|
- A package with at least one active hold is never
|
|
`eligible_for_deletion` regardless of `expires_at`.
|
|
- `POST /packages/{id}/retention/holds/{hold_id}/release` requires a
|
|
reason; emits `v1.retention.hold_released`.
|
|
- Test: hold applied → expiry passes → eligibility stays `false`;
|
|
hold released → eligibility flips to `true`.
|
|
|
|
## D3.4 - Deletion Eligibility Sweeper
|
|
|
|
```task
|
|
id: ARTIFACT-STORE-WP-0003-T004
|
|
status: done
|
|
priority: medium
|
|
state_hub_task_id: "fe13cd0d-aab7-4e0a-a7df-e6e535d4099b"
|
|
```
|
|
|
|
Acceptance:
|
|
|
|
- A scheduled task (cron-style configurable interval; default 1 hour)
|
|
scans packages whose `expires_at` has passed and no active hold
|
|
exists, and emits `v1.retention.deletion_eligible` events.
|
|
- The sweeper is idempotent: events are emitted at most once per
|
|
package per eligibility transition.
|
|
- The sweeper is invokable as a CLI subcommand for tests:
|
|
`artifactstore retention sweep`.
|
|
|
|
## D3.5 - Audit Surface For Retention
|
|
|
|
```task
|
|
id: ARTIFACT-STORE-WP-0003-T005
|
|
status: done
|
|
priority: medium
|
|
state_hub_task_id: "7dce0c92-76d6-4bfc-bbc5-8e18b96139d2"
|
|
```
|
|
|
|
Acceptance:
|
|
|
|
- `GET /packages/{id}/retention/history` returns the ordered list of
|
|
retention events for a package.
|
|
- The default response is the JCS projection; CBOR is available via
|
|
`Accept: application/cbor`.
|
|
|
|
## Success criteria
|
|
|
|
- A guide-board run can be ingested, given `release-evidence`, later
|
|
extended once, held for a quarter, released, swept, and marked
|
|
eligible — all visible through both `retention_state` and the
|
|
event log.
|
|
- No bytes are deleted by this workplan; that is WP-0006.
