Reconcile uncertain procurement submissions before retrying
A timeout followed by retry creates duplicate requests. Retain one submission key until resolved.

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.
- CFORM-102 · Link procurement error summaries to affected fields
- CFORM-101 · Preserve procurement amount precision during editing
- CFORM-103 · Remove obsolete shipping fields on procurement category changes
- CFORM-104 · Allow earlier procurement corrections after final-step errors
- CFORM-105 · Show acknowledged and unsaved procurement draft states
- CFORM-107 · Migrate one procurement draft schema transition
- CFORM-108 · Bind procurement review to the exact submission snapshot
Acceptance criteria
- Retry reuses key
- Success locks snapshot
- Unknown outcomes expose status lookup
Implementation constraints
- Timeout alone cannot prove failure.
Verification to include
- Submit then retry
- Timeout after adapter acceptance
Deliverables
- Submission coordinator and timeout case
Rollout and recovery
Pause retries while allowing lookup.
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.
