Ships the SDK-independent half of the Matter Bridge production work:
## `matter::bridge` — endpoint tree assembly
`build_bridge_tree(nodes) -> BridgeTree` walks a list of `(node_id,
friendly_name, [EntityKind])` tuples and produces the Matter endpoint
graph the SDK will materialise:
EP 0 (BridgedDevicesAggregator)
EP 1 (BridgedNode for "Bedroom")
EP 2 (OccupancySensor for Presence + PersonCount vendor attr)
EP 3 (OccupancySensor for SomeoneSleeping)
EP 4 (GenericSwitch for FallDetected)
EP 5 (BridgedNode for "Living") …
Key invariants enforced by tests:
- `PersonCount` collapses onto Presence's endpoint as a vendor
attribute, never gets its own endpoint
- Biometric entities (HR/BR/pose) are skipped entirely — they
never appear in the tree
- Every child endpoint carries `BasicInformation` cluster
- Endpoint IDs are monotonic + unique (verified by sort+dedup test)
- Empty node list yields just the root aggregator
- Multi-node bridges keep per-node endpoint isolation
- `endpoint(id)` lookup resolves every assigned ID
## `matter::commissioning` — setup-code generation
`SetupCodeInput::dev(passcode, discriminator) -> ManualPairingCode`
produces the 11-digit human-readable Matter pairing code that users
scan/enter into Apple Home / Google Home / HA Matter integration.
Validates against Matter Core Spec §5.1.6.1 disallowed-values list
(11111111, 12345678, 87654321, all-same-digit patterns, 0). Rejects
oversized passcode (≥2^27) and discriminator (≥2^12).
The Verhoeff check digit is computed per spec §5.1.4.1.5 — full
D/P/INV tables transcribed. The check digit appended to the body is
self-consistent (verified by a recompute-and-compare test).
`ManualPairingCode::display_4_3_4()` returns the dashed form
(`1234-567-8901`) controllers actually display.
Bit-packing is a placeholder for v0.7.0 — the chunk values are
hashed-then-mod into their decimal widths so the output is
deterministic + input-sensitive + Verhoeff-valid, but not yet
bit-perfect spec-compliant. The fully spec-compliant code (with QR
base-38 payload) lands at P8b when `rs-matter` is integrated; see
ADR-115 §9.10. This module gives the SDK layer a stable testable
contract to build against.
## Tests
- 16 cluster mapping (existing)
- 11 bridge assembly (new): aggregator root, branch-per-node,
PersonCount collapsing, HR/BR skip, BasicInformation cluster on
every endpoint, monotonic+unique IDs, total endpoint count, lookup,
multi-node isolation, empty-node list
- 11 commissioning (new): dev VID/PID defaults, disallowed-passcode
rejection (12 spec values), oversized-passcode rejection,
oversized-discriminator rejection, canonical test vectors accepted,
11-digit code always, 4-3-4 display format, determinism, sensitivity
to passcode change, sensitivity to discriminator change, Verhoeff
self-consistency, invalid-input early return
Total lib tests: **410 passed**, 0 failed, 1 properly ignored.
