Phase 3 Plan: Integration, Interoperability, and Submission (Gateways 7-8)
Scope
- Gateway 7: end-to-end integration and interoperability hardening
- Gateway 8: documentation, packaging, and final submission quality
Objectives
- Prove complete round-trip behavior under realistic conditions.
- Close interoperability gaps before submission freeze.
- Produce a complete, reproducible, judge-ready package.
Why This Phase Is Separate
- Integration and submission quality are evidence-heavy and schedule-sensitive.
- Isolating this phase ensures final weeks are used for hardening and proof, not net-new architecture.
Workstreams
- End-to-end integration and stress validation
- Interoperability exchange and issue closure
- Submission evidence assembly and reproducibility verification
- Documentation and examples
Week-by-Week Plan
Weeks 15-16 (Gateway 7)
- Engineer B (lead)
- Execute round-trip matrix: code -> frame -> I/Q -> decode -> parse.
- Validate runtime targets and reliability under sustained runs.
- Engineer A
- Validate normative behavior alignment across all integrated paths.
- Engineer C
- Coordinate interoperability exchanges and discrepancy triage.
- Developer A + B + C
- Close integration defects, stabilize automation, and lock regression suites.
Exit criteria:
- End-to-end tests pass under defined scenarios.
- Interoperability mismatch backlog is triaged and prioritized with owners.
- Performance and reliability metrics are captured with reproducible scripts.
Weeks 17-18 (Gateway 8)
- Engineer A
- Final architecture/spec alignment narrative and rationale updates.
- Engineer B
- Final validation matrix, benchmark narrative, and compliance statements.
- Engineer C
- Final interoperability and operations narrative with issue-closure evidence.
- Developer A
- Finalize code/encoding evidence bundles and examples.
- Developer B
- Finalize frame/signal usage docs and setup walkthroughs.
- Developer C
- Finalize automation scripts, artifact integrity checks, and reproducibility outputs.
Exit criteria:
- Submission package is complete and internally consistent.
- Build/run/test instructions succeed in clean-room environment.
- All required gateway evidence references are valid and accessible.
Submission Freeze Model
- T-7 days: feature freeze (bug fixes only)
- T-5 days: full clean-room build/test/benchmark rerun
- T-3 days: interoperability rerun and evidence refresh
- T-2 days: artifact hash and integrity verification
- T-1 day: final submission audit
Risks and Mitigations
- Risk: late interoperability regressions
- Mitigation: fixed exchange cadence and mandatory rerun after critical fixes.
- Risk: submission evidence drift
- Mitigation: artifact-hash checks and two-pass consistency audits.
Phase 3 Definition of Success
- Gateways 7-8 complete with full evidence chain.
- Submission package is reproducible, coherent, and review-ready.
