Project context
A fictional document workspace wants to measure upload completion and failure. Its prototype sends filenames, document titles and raw errors to general analytics. Replace that path with a minimal event contract using synthetic traffic.
Setup prerequisites
- Create synthetic upload workflows and a local collector that captures received payloads.
- Define measurement questions and a separate restricted diagnostic store fixture.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Use a random operation ID limited to one workflow and its bounded retry window.
- Exclude account, document and contact identifiers from the ID.
- Document linkability within the operation rather than calling the event anonymous.
Implementation constraints
- Keep subject mapping outside the generic sink; collect correlation only when required for the stated question.
Verification to include
- Retry one operation and verify intended correlation, then start another with a new ID.
- Inspect IDs and payloads for subject or document fields.
Deliverables
- Correlation lifecycle and identifier tests
Rollout and recovery
Version the schema and stop emitting direct identifiers before comparing reports.
Value of the work
For the engineer: Practice minimization, safe failure handling and correct aggregates.
For the team: Produce useful operational measurements with a reviewable collection boundary and disclosure regression suite.
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.
