📝 WalkthroughSummary by CodeRabbit
WalkthroughThe design document defines desire cleanup as a cleanup job. It records rejected applier-goroutine and per-management-cluster sweeper approaches. The selected design uses Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: 🟡 Moderate · up to The proposed centralized cleanup flow still lacks clear rules for identifying orphaned resources and handling already-deleted resources, which could lead to incorrect deletions or cleanup records that remain indefinitely. Authorization boundaries and desire identity handling also need to be specified, so the PR is not merge-ready until these issues are clarified or explicitly accepted.

- Line 52: Correct the spelling errors in the hyperfleet-applier documentation:
replace “sweeb” with “sweep” and apply the requested spellings “management,”
“orphaned,” and “decommissioning” at the referenced occurrences.
- Around line 68-69: Update the desire-sweeper resource-reference validation so
it creates a DeleteDesire only when an authoritative lookup confirms the
resource_id is not found. Treat timeouts, 5xx responses, authorization failures,
stale reads, and incomplete pagination as unknown and fail closed without
scheduling deletion.
- Around line 68-69: Update the garbage-collection design around the sweeper’s
DeleteDesire producer to define its authorization identity, including whether it
acts as the original adapter or a privileged system identity, and ensure
ownership validation accepts that identity. Specify idempotent upsert or
deduplication behavior for the DeleteDesire identity tuple.
- Line 70: Update the garbage-collection cleanup flow to remove or tombstone the
orphaned ApplyDesire before completing cleanup, in addition to DeleteDesire and
ReadDesire. Correlate the applier’s successful deletion report using the full
desire identity, including type, and ensure ApplyDesire cannot recreate the
Kubernetes resource during cleanup.

Should we also be deleting the ApplyDesire?

yes, the WIP store in hyperfleet-applier disposes the apply desire when a delete desire is created. same behavior should apply, but the owner check must not apply to the sweep job

Awesome if you can explicitly call that out in the doc, so the apply is removed by the applier on creation of the delete desire

In `@hyperfleet/docs/spike-desire-garbage-collection.md`:
- Around line 72-74: The sweeper exception must be limited to validated orphan
cleanup rather than bypassing owner authorization globally. Define an
authenticated sweeper identity and authorization boundary, validate that the
target desire is orphaned before allowing deletion, and make cleanup idempotent
with deduplication based on the full desire identity; update the ownership
contract around DeleteDesire and ApplyDesire accordingly.
- Around line 70-74: Update the sweeper lifecycle description to specify that
creating a sweeper DeleteDesire removes or tombstones the orphaned ApplyDesire
before remote deletion, regardless of the owner-field check. Require applier
deletion reports to correlate against the full desire identity, including type,
so retries or replays cannot recreate resources or remove the wrong cleanup
record.

- Line 70: Update step 3 of the garbage-collection flow so a remote deletion
result of NotFound is treated as successful, alongside confirmed deletion,
before removing the associated DeleteDesire and ReadDesire.
- Around line 68-69: Clarify the orphan-detection step before creating
DeleteDesire by defining the authoritative terminal hyperfleet-api state:
require the resource’s owner relationship to be absent or invalid and its
deletion timestamp to indicate soft deletion, rather than relying only on an
invalid resource reference. State the exact conditions that make resource_id
eligible for cleanup.
