release: 2.8.0

Release 2.8.0 — stabilization branch

All 2.8.0 milestone PRs have been retargeted onto release/2.8.0 and squash-merged in dependency order. Conflicts + Room schema renumbering were resolved on each PR branch (verified by per-PR CI + local build/lint before merge).

⚠️ Do not merge to main until this PR's cumulative CI is green and the release is signed off.

Merged (8 PRs)

Order	PR	Schema	Status
1	#5585 feat(ai) App Functions	—	✅ merged
2	#5633 feat(car) Car App	—	✅ merged
3	#5373 feat(search) FTS5	v39	✅ merged
4	#5586 refactor Remove AIDL (pivot)	—	✅ merged
5	#5701 feat Air quality	v40	✅ merged
6	#5714 feat(node) msh.to links	v41	✅ merged
7	#5275 feat(discovery)	v42	✅ merged
8	#5735 perf Baseline Profile	—	✅ merged

Schema serialization (resolved)

main was at Room v38. All four DB PRs originally claimed v39; serialized by merge order to v39 / v40 / v41 / v42 — each renumbered on its branch (bump version, re-chain @AutoMigration, regenerate NN.json via Room export, kept FTS5's 39.json). Each migration validated by Room codegen at build time.

Post-merge API fixups (from #5586 AIDL removal)

The AIDL-removal pivot moved/renamed APIs that later PRs consumed; fixed on the respective branches:

• DataPacket.{ID_BROADCAST,ID_LOCAL,PKC_CHANNEL_INDEX} → NodeAddress.* (constants moved to NodeAddress)
• RadioController moved core.model → core.repository
• radioController.getPacketId() → generatePacketId()
• SendMessageUseCase now returns Int (App Functions) atop refactor: Remove AIDL API and modernize service architecture #5586's ContactKey parsing

Deferred

• feat: firmware lockdown mode (provision / unlock / lock-now) #5439 firmware lockdown — needs proto LockdownAuth.max_session_seconds / disable + LockdownStatus.State.DISABLED, merged on protobufs develop (#916, #929) but not yet on master (no develop→master sync PR open). Add to 2.8.0 in a follow-up once proto syncs. Proto submodule stays at 6b1ded4 (master HEAD) throughout.

Version / CI

• Opening commit bumps VERSION_NAME_BASE → 2.8.0 (versionCode stays git-derived).
• Added release/** to the Pull Request CI branches trigger so milestone PRs into the release branch get full CI. (Note: this carries to main on merge — keep as policy or revert before the release→main merge.)
