REPO-OWNERSHIP.md

Repository ownership (phase 1: one writable source per app)

Status 2026-10-27. Implements the first step of REPOSITORY-TOPOLOGY.md: apps now live in techmore/mseries-sdk-apps (compared at origin/main 40d4445c4414e83da5893500528e088ec599af30). The OS repo still holds older duplicate copies. Those are now frozen migration snapshots: nothing is deleted, moved or archived, but PRs that edit them fail the Frozen paths guard CI check (label allow-frozen-edit overrides). The guarded list is ci/frozen-paths.txt; each frozen directory has a FROZEN.md. Branch rules: BRANCHING.md. Functional duplicates (Python/Rust/Vala twins, duplicate launchers) are marked, not removed, in LEGACY-DUPLICATES.md.

Method: real trees compared with diff -rq between git archive origin/main of the SDK repo and this checkout (dev at 7478f2fe). Phase 2 (kernel split) is owned by another session; Kernel rows are only tagged.

Apps already owned by the SDK repo (frozen here)

Path in OS repo	SDK repo state
rust/claude-pantheon-rs	Newer in SDK (plugin registry; 6 files only in SDK, 7 changed)
rust/mseries-messages	Newer in SDK (Signal channel, signal.rs; 5 files changed)
rust/mseries-pantheon-kit	Newer in SDK (diff timeline, timeline.rs; lib.rs changed)
mseries/battery	One test file differs (test_battery_enhance.py); reconcile in SDK
mseries/diskspace-app	Identical except test.sh
mseries/phone-setup	Identical (SDK tree has a stray __pycache__; remove there)
rust/granite-smoke, msdk, msdk-gtk, mseries-ai, mseries-apple-dev, mseries-broker, mseries-diskspace, mseries-dock, mseries-greeter, mseries-power, mseries-reply, mseries-signal-import, mseries-system-monitor, mseries-update-core, mseries-updates	Identical
mseries/sdk-tests, sdk-bench, sdk-status-host, messages-mcp, polybagger-print-manager, updates-app, fleet-shepherd	Identical
Docs: APP-BUILDING-GUIDE.md, DOCK-SDK-SPEC.md, RUST-PANTHEON-SDK.md, RUST-PANTHEON-CLIENTS.md, SDK-*.md (13 files)	Identical (guarded by path; no banner added)

Caveats: mseries-update-core still bundles the OS-owned root helper with the app-facing contract, and mseries-power backs the OS power policy. Both are frozen per the plan; use the label for helper/policy changes until the contract split in REPOSITORY-TOPOLOGY.md lands. Also identical but not frozen (decide in later phases): BATTERY-ETA.md, BATTERY-PROFILER.md, MESSAGES-PARITY.md, MESSAGING-STATUS.md, install-battery*.sh, install-phone-setup.sh, install-messaging-bluez.sh.

SDK-only (nothing to freeze here)

rust/mseries-image-studio, mseries/image-studio, rust/torrential. In flight: Signal Pantheon as mseries/signal-pantheon (SDK PR #14). SDK rust/Cargo.toml lists mseries-image-studio and drops pantheon-compositor; the OS workspace keeps the compositor, so the two Cargo.toml / Cargo.lock files are intentionally independent and not frozen.

Exists only in the OS repo: candidates to import (not imported now)

Path	Note
mseries/claude-pantheon-native	C/Meson client; SDK has the Rust claude-pantheon-rs only
mseries/torrential-native, mseries/TORRENTIAL-PORT.md	SDK imported rust/torrential with history (#15); confirm what native/port material is still needed
mseries/signal-wingpanel, signal-launcher.sh, install-signal*.sh, SIGNAL-PANTHEON-DESIGN.md	Signal Pantheon moves with SDK PR #14; deferred per MESSAGING-STATUS.md
mseries/smart-reply, SMART-REPLY-DESIGN.md, install-smart-reply.sh	Pairs with rust/mseries-reply
mseries/tether, TETHER-CONTINUITY.md, omdrop*, orchard*, horizon-rdp, opencode-desktop	Standalone apps; classification needs an owner decision

Classification of the rest of rust/ and mseries/

Class	Paths
OS (stays)	rust/pantheon-compositor (SDK keeps only the vendored protocol XML; its drift check treats this repo as source of truth), pantheon-rust-compositor, gala-*, window-*, dock-*, docked-lid, quick-settings, panel*, wingpanel-tests, *-wingpanel and install-*wingpanel* (clockright, codexbar, repobar, share-eyes, t3, troubleshooter), codexbar*, repobar*, theme, desktop-notifications, dark-mode, display-*, brightness, keyboard-backlight, audio, airplay, power, touchid-settings, icloud-passwords, image-actions, screenshot-shelf, work-mode, ui-scale, netspeed, update, releases, release, debs, packages.arm64, patches, customizations, minimal-system, enhance*, user-enhance.sh, post-install.sh, validate.sh, ci, remaining install-*.sh, lib-*.sh, test-*, machine-lab, vms, muvm-source.sh, modrun.py, maintenance, procedures, tools
Kernel (phase 2, other session)	aurora, aurora-sep, aurora-touchid*, AURORA-SECOND-BOOT.md, boot, fairydust, hardware, lid-trace, KERNEL-*.md, check-kernel-config.py, test-kernel-config.py, install-initramfs-crossbar.sh, install-boot-isolation.sh, USB-C-DOCK-DP-ALT-MODE.md, FIRMWARE-WIFI.md, upstream, upstreams, upstream-audits, UPSTREAM-PINS.md
Hub / docs	All other top-level *.md (ROADMAP, OS9-HANDOFF, BRANCHING, REPOSITORY-TOPOLOGY, PORT-MAP, audits, designs, runbooks), receipts, benchmarks, local-ai, dictation, docs/ and the Pages site

The Kernel and OS lists are grouped by name and judgment, not by exhaustive file audit; items that fall between classes should be settled in phase 2 or later.

Anything listed under "already owned by the SDK repo"	techmore/mseries-sdk-apps

Removed from this repo (2026-10-27)

rust/mseries-diskspace, rust/mseries-updates, rust/mseries-power, rust/granite-smoke, mseries/diskspace-app and mseries/updates-app (with their two CI workflows and validate.sh checks) were deleted here; the source of truth is techmore/mseries-sdk-apps. Still here: rust/mseries-update-core (mseries-pantheon-kit depends on it and it holds the OS-owned root helper) and rust/claude-pantheon-rs (rust/msdk tests, msdk.yml and mseries/sdk-tests read its sdk/t3.* files; remove it together with msdk).
