+## Implementation report
+
+Integration report:
+
+Merged implementation branch into orchestration branch:
+- branch: `impl/00001KT0Z4BK8-plugin-package-discovery`
+- implementation commit: `3c674a70 docs: propose plugin package distribution`
+- merge commit: `2b9dae48 merge: plugin package design`
+
+Reviewer result:
+- `approve` recorded from `yoi-reviewer-00001KT0Z4BK8`.
+
+Validation in Orchestrator worktree `/home/hare/Projects/yoi/.worktree/orchestration`:
+- Passed: `git diff --check`
+- Passed: `test -f docs/design/plugin-packages.md`
+- Passed: `grep -n 'plugin-packages.md' docs/README.md`
+
+Cargo validation:
+- Not run because the merged change is documentation-only.
+
+Notes:
+- The proposal is intentionally design-only. Exact manifest/Profile schema, lock-file format, archive limits, cache path, and WASM ABI remain follow-up implementation work.
+- Orchestrator worktree is clean after validation.
+
+Cleanup planned:
+- Stop related coder/reviewer Pods.
+- Remove only child implementation worktree/branch for this Ticket.
