From 6364e0f7d8452d143d9e7f82aee5e97155c194a4 Mon Sep 17 00:00:00 2001 From: ruv Date: Sat, 23 May 2026 14:36:10 -0400 Subject: [PATCH] =?UTF-8?q?feat(adr-115):=20P8=20=E2=80=94=20Matter=20brid?= =?UTF-8?q?ge=20tree=20+=20commissioning=20code=20(38=20tests,=20lib=20tot?= =?UTF-8?q?al=20410)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
