+**Date:** 2026-04-13
+**Session:** 11c4bd2f-216e-4779-81bf-26d34a4fcaeb
+
+### Changes
+- Updated `design/rules-plugin-extension.design.md` from v1.8 to v1.10 so the optional plugin companion now includes one operator-facing session coordination support skill while keeping root RULES as semantic authority.
+- Updated `changelog/rules-plugin-extension.changelog.md` to v1.10 for the plugin companion skill rollout.
+- Renamed the plugin package identity from `rules-compact-extension` to `claude-code-rules` and updated `plugin/.claude-plugin/plugin.json` plus `plugin/.claude-plugin/marketplace.json` to v1.3.1.
+- Added `plugin/skills/session-coordination-bridge/` with `SKILL.md` plus focused support docs for overview, capability detection, coordination flow, request contract, and examples.
+- Updated `plugin/README.md`, `README.md`, `TODO.md`, and `phase/SUMMARY.md` so the optional extension layer now documents both compact lifecycle hooks and the new support skill, including migration guidance for older `rules-compact-extension@darkwingtm` installs.
+- Updated compact visible runtime signal wording and persisted compact-state schema prefixes from `rules-compact-extension/*` to `claude-code-rules/*` so runtime behavior stays aligned with the new plugin identity.
+- Added bounded `patch/session-coordination-bridge-skill-rollout.patch.md` plus `phase-041-01` and `phase-041-02` artifacts for the skill rollout wave.
+
+### Summary
+The optional RULES plugin companion now exposes `claude-code-rules:session-coordination-bridge` as a bounded support skill and uses one coherent `claude-code-rules` plugin identity across install flow, runtime signals, and persisted compact state.
