type: project

Phases 1–8 complete. GAAF Compliance Foundation (IHUB-WP-0009) complete.

**Why:** All 8 phases of IHF v0.1 spec delivered. GAAF-2026 review identified critical gaps (no extension layer, no type registries, no hub kind classification, no fitness functions). IHUB-WP-0009 addressed all gaps as a prerequisite to Phase 9.

**How to apply:** Active workplan is IHUB-WP-0010 (Phase 9 — External API). Start with `/ralph-workplan workplans/IHUB-WP-0010-ihf-phase9-external-api.md` when ready. Type registries must remain seeded; all new type discriminators must reference a registry (enforced by fitness function Test 4 in CI). Domain hubs must register via `HubCapabilityManifest` before creating hub-owned types.

GAAF scorecard post-WP-0009: 3.34/5.0 (Usable but vulnerable — Phase 9 ready). Target ≥3.5 at Phase 10 exit.
