Project context
Fictional procurement team Northroom collects purchase requests in a browser form. Work uses local stubs and cannot place purchases.
Setup prerequisites
- Create synthetic categories and conditional request fields.
- Stub draft revisions and submission outcomes.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Payload excludes inactive fields
- Discard prompts identify entered data
- Cancel preserves category
Implementation constraints
- Hidden inputs are not a serialization policy.
Verification to include
- Switch empty category
- Cancel populated category switch
Deliverables
- Conditional payload projection
Rollout and recovery
Disable category changes until removal is corrected.
Value of the work
For the engineer: Practice state boundaries and form schema transitions.
For the team: Inspect how hidden obsolete data and duplicate requests are prevented.
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.
