Release notes — Muse Code stable promotion (#231)

Date: 2026-10-02 (America/New_York) Provider: `muse` (display name Muse Code) Change: `experimental` → `stable`

Highlights

• Promote provider id `muse` from `experimental` to `stable`. No aliases; `muse-code`, `muse-spark`, `spark`,

and `meta` stay rejected.

• `aiwg use all --provider muse` now installs the managed `SessionStart` hook and an opted-in `--mcp` profile

(previously skipped by the kernel-only `use all` path).

• Skills deploy to project `.agents/skills`; `--scope user` uses `$XDG_CONFIG_HOME/muse/skills` and fails

closed on bad XDG metadata.

• Sessions import from `muse export` documents, or from native logs with an explicit `--muse-root`.
• The `muse exec` Ralph adapter remains optional (`AIWG_MUSE_RALPH_ENABLED=0` disables it).

Evidence checklist

• [x] Linux PUW (required) — `docs/integrations/muse-linux-puw.md`
• [x] macOS PUW — waived by the maintainer, 2026-10-02: Linux verification sufficient for release
• [x] Windows/WSL PUW — waived (same guidance)
• [x] Skills deploy + `AGENTS.md` bridge + session export import (PUW)
• [x] Security review — `docs/security/muse-path-security-review.md`:

no `settings.json` clobber (opt-in, backup, operator `aiwg` key never replaced); hooks-outside-sandbox warning documented in the provider reference

• [x] Capability-matrix + provider-definition status flip (`status: stable`)
