Phase 3 · Controlled Closeout · Rev 1.0
Cross-Project Materials Integration — Complete
The Phase-3 dependency architecture is closed: seven Aurora material-consumer gateways now point to one canonical Materials Engineering authority for identity, evidence, availability, conflicts and reusable base-material context. Missing evidence remains visibly source-gated rather than guessed.
Ownership Flow
Canonical truth separated from project qualification1 · Project nominates
Portal, Warp/Space, Communications/QFL, Power, BioSystems, Sustainability and Component/Prototype teams identify candidate material needs.
→
2 · Materials Engineering controls
MAT-ID, aliases, source provenance, evidence status, availability, conflicts, reusable base-material context and shared website links.
→
3 · Consuming program qualifies
Project-specific process windows, safety factors, procurement/lot controls and E5 design allowables remain with the consuming program.

Phase 3 Exit Criteria
Architecture complete; evidence continues to maturePASS Seven roadmap consumer domains are represented by controlled gateways.
PASS Materials Engineering is the canonical base-material record owner.
PASS Project-specific qualification and E5 allowables remain outside shared reference claims.
PASS Every current validated material link points to a canonical MAT-ID rather than a duplicate project copy.
PASS Candidate families without verified property evidence are visibly SOURCE_GATE_PENDING.
PASS Machine-readable controller, dependency, reuse and source-gate registers are published with the build.
PASS All application gateways expose the Phase-3 dependency state and route back to the shared architecture.
PASS Numerical property promotion remains governed by the E0–E5 evidence model.
Phase 3 closed. Closure is architectural, not a claim that every candidate family now has verified property values. New Phase-2/Engineering-Depth records may enrich these links later without reopening the Phase-3 ownership model.
