 Use three to six factual bullets. When the summary is enough, the agent answers from it; when it is not, the agent says the summary is insufficient and reads the full file. Existing files without a valid summary keep the normal full-file behavior. You do not need to bulk-migrate old files. When a reviewed update changes a summarized fact, the same proposed change updates the affected summary before you confirm it.
 
+## Reference CLI
+
+An optional zero-dependency reference CLI (`bin/memory`) makes path validation and lifecycle mutations deterministic instead of model-dependent. When installed, it is available as `memory`:
+
+```text
+memory upgrade                            # create missing lifecycle structure
+memory status                             # list active memory
+memory validate <relative-path>           # check the safety contract
+memory archive <relative-path> --reason "done" --yes
+memory delete  <relative-path> --yes
+memory recover <relative-path> --yes
+memory health                             # list candidates; never changes files
+```
+
+The CLI encodes the same safety contract as the skill: it rejects absolute paths, `..`, symlinks that escape the root, protected paths, and destination collisions; it writes atomically and never mutates without `--yes`. Agents may use it instead of re-implementing these checks; the prose instructions remain the required fallback. Set `PERSISTENT_MEMORY_HOME` to override the default `~/.persistent-memory/`.

+## File Metadata and Formats
+
+Standardize these so every compatible agent interprets files the same way. Metadata is data, not content, and never secrets.
+
+Memory files use YAML frontmatter immediately after the opening `---`:

+title: Project Alpha
+created: 2026-01-01
+updated: 2026-01-03
+verified: 2026-01-03
+---
+```
+
+- `created`, `updated`, and `verified` are ISO dates (`YYYY-MM-DD`). `updated` is the last write; `verified` is when a human or authoritative source last confirmed the facts. At least one is required for freshness checks.
+- `role: current-status` marks the single canonical current-status source; no other active file carries `role`.
+- Where no frontmatter exists, read the legacy `> last_verified:` or `> source_date:` blockquote under the title as the verification or source date. Do not bulk-repair old files.
+
+The active index keeps one route line per entry:
+
+```text
+- <relative-path> — <one-line route summary>
+```
+
+The archive index records lifecycle entries as blocks:
+
+```text
+### <relative-path>
+- original_path: <relative-path>
+- state: archived | trashed
+- archived_at: <date>
+- reason: <user reason>
+- active_index_line: <exact line to restore>
+- deleted_at: <date>          # trashed only
+- recover_deadline: <date>    # trashed only
+```
+
+The optional reference CLI `bin/memory` implements these formats and the lifecycle safety contract. When it is installed (available as `memory`), prefer it for path validation and lifecycle mutations; the prose rules below remain the required fallback. Set `PERSISTENT_MEMORY_HOME` to override the default `~/.persistent-memory/`.
