Track notification and cache cleanup separately from the primary profile row

Practice briefBugAdvanced

The operation reports success after deleting the database row even though a notification snapshot and cache entry still show the member’s details.

Your next step

Review it, then add it to your workspace.

The board opens an editable draft; nothing is saved until you confirm it. Sign-in and workspace permissions apply, and Demo boards remain ephemeral.

Project context

A fictional collaboration product lets a member request removal of their personal profile. Search, notifications and cached displays retain copies after the primary row disappears. The exercise uses a documented product deletion policy and synthetic identities.

Setup prerequisites

  • Create local profile, search-index and notification fixtures with controlled provider failures.
  • Define synthetic members, organizations and a current-session authorization fixture.

Preceding work

Complete these dependencies, or supply their agreed outputs before taking this ticket.

Acceptance criteria

  • Track required locations with independent pending, confirmed and failed states.
  • Differentiate already absent from unavailable or unauthorized provider responses.
  • Advance overall completion only when the declared required locations satisfy the policy.

Implementation constraints

  • The location registry is versioned for each operation so a later implementation change cannot silently rewrite its promised scope.

Verification to include

  • Fail cache cleanup after database removal and verify a partial state with a retryable location.
  • Return an authorization error from notifications and confirm it cannot be counted as confirmed absence.

Deliverables

  • Location progress model and partial-cleanup fixtures

Rollout and recovery

Enable adapters one at a time in the local exercise; unsupported locations remain explicitly unresolved.

Value of the work

For the engineer: Practice distributed cleanup, identity scope, idempotency and accurate user-facing lifecycle states.

For the team: Produce a reviewable deletion workflow and copy inventory for adaptation to an approved company policy.

Evidence boundaries

Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.

Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
