Bound diagnostic retries independently of application retries
Running the diagnostic tool triggers the client's normal retry loop and floods the local test endpoint.

Project context
A fictional desktop sync client works on one office network but intermittently fails on another. Application retries hide whether DNS, IPv6, or transport limits are responsible.
Setup prerequisites
- Author synthetic packet traces and local IPv4/IPv6 endpoint doubles; use no third-party scanning or captured personal traffic.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Use a separate fixed diagnostic attempt budget.
- Disable application retry chaining.
- Stop immediately on explicit cancellation.
Implementation constraints
- Targets must match the authorized local allowlist.
Verification to include
- Run the declared number of attempts.
- Cancel or supply an unapproved target and verify no further connections.
Deliverables
- Diagnostic execution guard.
Rollout and recovery
Default to offline analysis; require explicit local target configuration.
Value of the work
For the engineer: Practice layered network diagnosis and reproducible troubleshooting.
For the team: Produce precise support diagnostics that distinguish application defects from connectivity conditions.
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.
