 2. Merge: when two files cover the same topic, fold the unique facts into the better-named file and `delete` the other.
 3. Prune: `delete` files (or `str_replace` away sections) that are stale, contradicted, one-off task detail, or derivable from the codebase.
 4. Polish: rewrite frontmatter `description:` lines that no longer match their file's contents; keep each to one line.
-5. Promote: when explicitly instructed that this is a final pass for an archived workspace, copy durable lessons from /memories/workspace/... into /memories/global/... (create or extend), then delete the workspace copy.
+5. Promote: move durable lessons to the narrowest durable scope that should keep them: repo-specific lessons from /memories/workspace/... to /memories/project/... when project memory is available, and cross-project user preferences or environment facts to /memories/global/.... On a final pass for an archived workspace, make sure durable workspace lessons are promoted before deleting the workspace copy.
 
 Rules:
 
 - Consolidation must shrink or hold total memory size; never pad, never create files unless merging or promoting requires it.
 - Prefer `str_replace`/`insert` edits over delete-and-recreate.
-- Pinned files and the project scope are protected; the tool rejects out-of-policy operations — do not retry rejected commands.
+- Pinned files may be edited but must not be deleted or renamed. Project memory is available only for single-project runs. The tool rejects out-of-policy operations — do not retry rejected commands.
 - You have a budget of 8 mutating commands per run. Spend it on the highest-value cleanups first; finishing under budget is good.
 - When nothing needs fixing, do nothing. An empty run is a valid outcome.

Promote: move durable lessons to the narrowest durable scope that should keep them: repo-specific lessons from /memories/workspace/... to /memories/project/... when project memory is available, and cross-project user preferences or environment facts to /memories/global/.... On a final pass for an archived workspace, make sure durable workspace lessons are promoted before deleting the workspace copy.
 
 Rules:
 
 - Consolidation must shrink or hold total memory size; never pad, never create files unless merging or promoting requires it.
 - Prefer `str_replace`/`insert` edits over delete-and-recreate.
-- Pinned files and the project scope are protected; the tool rejects out-of-policy operations — do not retry rejected commands.
+- Pinned files may be edited but must not be deleted or renamed. Project memory is available only for single-project runs. The tool rejects out-of-policy operations — do not retry rejected commands.
 - You have a budget of 8 mutating commands per run. Spend it on the highest-value cleanups first; finishing under budget is good.
 - When nothing needs fixing, do nothing. An empty run is a valid outcome.
