cloudinit-bot 82ae6cf5a2 docs(milestone): complete OpenYield v0.3 (Bearers & Documentation)
Milestone v0.3 complete. Feature type, tags v0.2.x. Two work-streams
shipped under one feature milestone:

(A) Bearers skeleton + tests (D-020 pattern, 7 x/* packages, zero ext deps):
- x/bridge (NEW): BridgeStatus enum (4), BridgeRoute by-ID-string refs
- x/exit (NEW): ExitStatus enum (5), ExitRoute, DEXSwap (opaque venue)
- x/bearers (EXT): OYSATLink surveillance-resistant LOCKED, OYQRCode idempotent
- x/partner (EXT): AnchorCredential (custody-provider-id empty in skeleton)
- x/hub (NEW): HubService enum (3), LendingCouponCapBps=800 LOCAL const (A-304)
- x/services (NEW): ServiceKind enum (4), window-id by-ID-string ref (A-307)
- x/bond (EXT): GrowthBond, ClampGrowth G-012 underflow guard, secondary market
All packages >=93.3% coverage. Both lexicon firewalls green. G-003 intact.

(B) Documentation deliverable (REQ-027 complete, 26-page MkDocs Material site):
- README.md + mkdocs.yml + docs/index.md
- docs/shared/ (7 pages): Six Principles, Bread Scale, Storage Pools, Watchers/Mirror, Lexicon, Vision
- docs/nomads/ (8 pages): Reach, Stash, Bearers, Maps-Pay, Pacts, Standing, Window
- docs/freeholders/ (8 pages): Signals, Standing, Stands-Guilds, Councils-Voice, Bonds, Partner Spectrum, Anchor Preview
- docs/reference/ (2 pages): Architecture, Components
- REQ-028: lexicon firewall extended to docs/ + README.md (lexicon_meta_docs_test.go, 5 tests incl G-013 walk-coverage + G-014 shared self-test)

Phases: P0 -> v0.2.0, P1 -> v0.2.1, P2 -> v0.2.2, P3 -> v0.2.3, P4 -> v0.2.4, P5 -> v0.2.5, P6 -> v0.2.6 (milestone release).

Requirements covered: REQ-010, REQ-022, REQ-023, REQ-024, REQ-025, REQ-026 (skeleton), REQ-027, REQ-028 (complete).
IDEATE-01..08 ratified and delivered.

Architecture

This is the architecture index for OpenYield. The mesh is built from 14 modular components and 6 cross-component interfaces, with a critical blocker chain that fixes the build order. The full governance source lives in .ciagent/oy/ARCHITECTURE.md; this page is the user-facing rewrite, kept lexicon-clean by the docs firewall.

The 14 modular components

# Component Vision § Phase
1 OY Chain & Mirror §7 P1
2 Cross-Chain & Exit §7 P3
3 Bread Unit & Root Basket §6, §16 P1
4 Bloom Engine §6 P1
5 Storage Substrate §5 P1
6 Identity, Standing & Citizenship §8, §9 P1
7 Window Primitive §10 P2
8 Pacts Suite (Pause, Ground, Stance, Cover, Stand Registry, Hub API, Bonds) §16, §17 P2
9 Mesh Experience (Maps, Pay) §8 P1
10 Organizational Primitives (Stands, Guilds) §11, §12 P2
11 Partner Spectrum & Forex §13 P2
12 Bearers & Processing Mesh §14, §15 P1
13 Fee Covenant §18 P1
14 Governance (Mesh/Guild/Stand Councils) §19 P2

The 6 cross-component interfaces

  1. Standing API — consumed by Identity, Window, Pacts, Orgs, Partners, and Governance. See Standing.
  2. Forge / Fold Interface — mints Bread against Root Basket assets only. See the Bloom Engine.
  3. Watcher Attestation Interface (the Mirror) — 9 Watchers, 6-of-9 quorum. See Watchers & Mirror.
  4. Window Lifecycle Interface — Holder-authorized, scope-bounded, revocable. See Window.
  5. Fee Covenant Interface — auto-decline, ceiling/floor enforced. See Six Principles.
  6. Voice / Council Interface — multi-source Voice, Mission Lock enforced. See Councils & Voice.

The critical blocker chain

The components build in a fixed order: OY Chain (1) → Bread/Root Basket (3) → Storage (5) → Identity/Standing (6), which then unblocks {Window (7), Pacts (8), Orgs (10), Partners (11), Governance (14)}. The Fee Covenant (13) blocks Pacts, Orgs, Partners, and Bearers — the fee shape must exist before any of those can ship. v0.3 adds the Cross-Chain & Exit layer (component 2) and the Bearers/Partner/Bond extensions; see Components for the x/ module map and the v0.3 phase status.
