Phase 4 Plan: Validation and Documentation (Weeks 19-21)
Scope
- Gateway 7: Integration Testing (10 Aug - 16 Aug)
- Gateway 8: Conformance Testing (17 Aug - 21 Aug)
- Gateway 9: Interoperability Testing (22 Aug - 25 Aug)
- Gateway 10: Documentation and Examples (26 Aug - 31 Aug)
Objectives
- Prove end-to-end compliance and reliability
- Deliver complete submission package with evidence
- Remove ambiguity for judges: every claim backed by artifacts
Why This Phase Determines Final Score
- This phase converts implementation completeness into scored evidence across integration, conformance, interoperability, and usability categories.
- Strong technical implementation without reproducible proof loses points; this phase ensures proof quality matches engineering quality.
Workstreams
- Integration and stress testing
- Conformance suite, PICS, and compliance report
- External interoperability exchange and reporting
- Documentation and runnable examples
Week-by-Week Plan
Week 19 (Gateway 7)
- Engineer B (lead)
- Execute complete integration matrix across duplex modes
- Run resynchronization, reconnect, and multi-channel scenarios
- Engineer A
- Verify behavioral consistency against section references
- Engineer C
- Lead interoperability readiness drills and execution runbook verification
- Developer A + B + C
- Fix integration defects, lock regression tests, and stabilize automation pipelines
Exit criteria:
- All integration tests pass
- Performance targets validated (<1 ms per frame, <50 KB/session)
- Stress runs show no leaks or unrecovered failure states
Why these steps:
- Integration matrix execution verifies system-level behavior across combinations that unit tests do not fully cover.
- Early stress and performance validation protects schedule by surfacing scalability defects before final packaging.
Week 20 (Gateway 8)
- Engineer A + Engineer B + Engineer C
- Finalize mandatory-feature conformance matrix
- Complete and verify PICS document
- Developer A + B + C
- Generate standardized test vectors (binary + JSON metadata)
- Automate conformance report generation and evidence packaging
Exit criteria:
- All mandatory features tested and passing
- PICS complete and consistent with implementation
- Compliance report evidence is reproducible
Why these steps:
- PICS and conformance matrix provide judge-readable evidence linking implementation to mandatory specification requirements.
- Test vectors in binary + JSON form create portable validation assets for both conformance and interoperability scoring.
Week 20.5 (Gateway 9)
- Engineer A
- Lead external session setup and protocol exchange
- Engineer B
- Capture anomalies and classify interoperability findings
- Engineer C
- Coordinate partner-team exchange logistics and live issue triage workflow
- Developer A + B + C
- Patch compatibility issues quickly, rerun validation, and regenerate exchange evidence
Exit criteria:
- Successful data exchange with at least one external implementation
- Cross-decoding of vectors successful
- Interoperability report completed
Why these steps:
- External exchange is the only reliable confirmation that implementation assumptions are not toolchain-local.
- Rapid patch-and-rerun loop is planned explicitly because interoperability issues are frequently discovered at integration boundaries.
Week 21 (Gateway 10)
- Developer B (docs tooling lead)
- Build API docs pipeline and user guide structure
- Engineer A
- Final architecture narrative and design rationale
- Engineer B
- Performance analysis narrative and test evidence mapping
- Engineer C
- Final interoperability narrative, operations runbook, and handoff readiness checklist
- Developer A
- Finalize caller/responder examples and troubleshooting notes
- Developer C
- Finalize submission automation, artifact integrity checks, and reproducibility scripts
Exit criteria:
- Reviewer can build and run from docs alone
- All public interfaces documented
- Examples execute and demonstrate key protocol paths
Why these steps:
- Judges must be able to build and run without tribal knowledge; documentation quality directly contributes to score.
- Working examples convert architecture and API docs into verifiable usability evidence.
Submission Freeze Plan
- T-5 days: feature freeze, only bug fixes allowed
- T-3 days: full clean-room build and test on separate machine
- T-2 days: submission artifact checksum and packaging
- T-1 day: final read-through of all required documents
- T day (31 Aug 2026): submit package and archive evidence
Why this freeze model:
- Controlled freeze windows reduce last-minute destabilization.
- Clean-room build/test validates reproducibility independent of primary developer machines.
Phase 4 Definition of Success
- Gateways 7-10 complete with full evidence chain
- Submission package is complete, reproducible, and reviewer-friendly
