 ## Milestone
-v0.3 — Bearers & Documentation (active milestone; feature type; tags run on the v0.2.x patch line)
+v0.4 — Refinement (active milestone; NFR type; tags run on the v0.3.x patch line)
+
+### v0.4 Scope (Refinement-only NFR — v0.3 post-hoc forward-references)
+
+v0.4 is a refinement-only NFR milestone: zero `feat:` phases. It lands the
+durability fixes v0.3 flagged but did not block on, sourced from REVIEW.md,
+AUDIT.md §193, and GRILL.md G-014. Live-runtime promotions of the v0.3 Bearers
+skeletons are out of scope (deferred to v0.5+).
+
+- **REQ-029** Lexicon firewall shared helper (`lexicon.SyntheticBannedStrings()`) — dedupe the synthetic self-test table between `lexicon_meta_test.go` and `lexicon_meta_docs_test.go`. Both meta-tests derive count + strings from the single `lexicon` package source, so a future banned-term addition updates both firewalls from one place. (GRILL G-014)
+- **REQ-030** Cross-package const-equality test — `x/hub.LendingCouponCapBps == x/bond.CouponCapBps` (and Floor). Test-only import (G-003 exempt). Catches silent mission-lock drift between hub LOCAL consts and bond D-028 consts. (REVIEW.md P2 / A-304)
+- **REQ-031** x/* lifecycle type shape-divergence review + alignment fixes — audit non-must-have lifecycle types across modules flagged by AUDIT §193; align where divergent without behavioral change. (AUDIT.md §193)
+- **REQ-032** Docs build CI — Gitea Actions workflow running `go test ./...` (lexicon firewall) + `mkdocs build` on every push; upload `site/` as a CI artifact. Full Gitea Pages publishing deferred if no hosting target configured. (D-046)
+
+### Milestone Type
+NFR (all phases are refactor/test/quality/chore). Phase 0 → `v0.3.0`; execution phases `v0.3.1..v0.3.3`; final phase patch `v0.3.4` IS the milestone release. No separate minor tag. The final-phase audit enforces the NFR purity gate (zero `feat:` commits).
+
+### Out of Scope (v0.4)
+- Live-runtime promotions: Exit/DEX, OY-SAT/OY-QR hardware, Hub API B2B, bond matching, L2 IBC rollout, Anchors onboarding (all `feat:`, deferred to v0.5+)
+- i18n / MkDocs internationalization (`feat:`, rejected by D-001 filter)
+- Yield Token, Travel + 11 service categories (ROADMAP Phase 4)
+- Cover Pool seniority mechanics (still deferred per PROJECT.md Q7)
+
+### Prior Milestones
+- v0.1 — OpenYield Foundation Init (COMPLETE; pre-MVP foundation skeleton; released as v0.0.9)
+- v0.2 — The Mesh (COMPLETE; skeleton + tests; released as v0.1.5)
+- v0.3 — Bearers & Documentation (COMPLETE; feature; released as v0.2.6)
+
+## Prior Milestone
+v0.3 — Bearers & Documentation (complete; feature type; tags ran on the v0.2.x patch line)
 
 ### v0.3 Scope (Bearers skeleton + Docs site — ROADMAP Phase 3 partial, plus a docs deliverable)
