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

- 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).

Maps & Pay

Maps and Pay are the day-to-day Mesh Experience a Nomad uses on the mesh. Maps finds services; Pay settles them. Both run over the bearers and read the Mirror so a Nomad can find and pay for a service on a surveillance-resistant bearer without an internet connection to OY Chain.

Maps

Maps is the directory of services a Nomad can reach. A service is anything a Partner or a Stand exposes to the mesh: a Care service, a SIM, a Vault, a Mailbox (preview of v0.3 P5 — see Pacts for the Hub API). Maps is sorted by geographic proximity (REQ-007): a Nomad physically closer to a service or its operator is shown that service first. There is no paid ranking; the order is proximity, not promotion.

Pay

Pay is how a Nomad settles a service. A payment is a transfer of Bread from the Nomad's Stash to the service operator's Stash, signed by the Nomad's Reach. The fee covenant floors and caps the fee; inside a Guild, a Hand-Pass is free at the protocol level (REQ-017). Pay runs over any bearer, first-to-deliver-wins.

Authorize, don't hand over

For recurring services a Nomad does not re-sign every payment. Instead the Nomad opens a Window to the service: a scoped, time-limited, rate-limited, revocable capability that lets the service pull value from the Stash within bounds the Nomad set. The Window is audited; the Nomad can revoke it at any time. This is the self-service principle in practice: the Nomad delegates a capability, not custody.

Find, pay, verify

A Nomad's loop is:

  1. Find a service on Maps.
  2. Pay once, or authorize a Window for recurring use.
  3. Verify the service against the Watcher attestations on the Mirror (see Watchers & Mirror).

See Stash for where the Bread comes from, Window for the delegation primitive, and Standing for how a service operator's history is measured.
