# memory-loop: remember

A wrongly saved memory gets recalled later *as if it were fact* — that is one
of the biggest sources of persistent hallucination. This gate blocks it at the
entrance.

## The gate (in order, before any write)

1. **State the candidate and its evidence.** What exactly would be saved, and
   how was it verified? An unverified inference is never saved — verify it
   first or drop it.
2. **Confirm the tier with the user:**
   - `tier: long` — keeps applying indefinitely (identity, policies,
     infrastructure facts, recurring preferences).
   - `tier: short` — consumed by a date or an event (schedules, in-flight
     work, decisions pending).
3. **If short, agree on the expiry:**
   - Absolute: `expires: YYYY-MM-DD`. The expiry sweep archives it on the
     first session *after* that date has passed — the expiry day itself is
     still live (exclusive boundary).
   - Conditional: `expires_when: "<event>"` (e.g. "after the release ships").
     Never auto-archived; you review it manually when the event happens.
4. **Write the memory file in the native format** — the usual frontmatter
   (`name`, `description`, `metadata`) — adding the lifecycle keys under
   `metadata`:

   ```markdown
   ---
   name: deploy-freeze-january
   description: Deploys are frozen until the audit completes
   metadata:
     type: project
     tier: short
     expires: 2026-02-01
   ---

   <the fact>
   ```

5. **Update the memory index** (`MEMORY.md` in the same directory) with a
   one-line pointer.

Optional: `salience: 1-5` (recall priority) may be added under `metadata`;
memory-loop does not enforce it — it is a hint for your own recall ordering.

## Keeping the dates honest

Two `metadata` dates drive the upkeep check, and both are cheap:

- `modified: YYYY-MM-DD` — set it whenever you change a memory's **content**.
  Editing the body while leaving this stale is what makes an index line and a
  file disagree without anything noticing.
- `reviewed: YYYY-MM-DD` — set it when you **re-verified** a memory and it was
  still true, with nothing to change. Without this there is no way to say "I
  checked, it holds", so the same file is flagged forever and the check trains
  you to ignore it.

Re-verification means you ran the command or read the source again — not that
the memory still sounds plausible.

## Compatibility contract

Files without a `tier` key are **outside the lifecycle** — the sweep never
touches them. That is the safe default for every memory that existed before
this plugin was installed. Never bulk-add `tier` to old files; tier them one
by one, through this gate, as they come up.

## When the upkeep check reports

The SessionStart upkeep check names memories untouched past
`memoryReviewDays`, index drift, orphans and broken index links. It never
writes. Offer `/memory-loop:consolidate` for anything it lists — except:

- **Untiered files.** Consolidation may not touch them (the compatibility
  contract above). Re-verify the fact yourself, then bring it through this gate
  as a tiered memory, or leave it exactly as it is.
- **`tier: short` with a conditional or missing expiry.** Nothing archives
  these — the sweep only acts on an absolute `expires:`. The question is not
  "is it old" but "did the event already happen": if it did, archive it; if it
  did not, leave it and set `reviewed:`; if it never will, convert it to
  `tier: long` or give it an absolute date, through this gate.
- **A memory that is simply old.** Age is not wrongness. If it still holds,
  the whole repair is one `reviewed:` line.

## When the sweep reports

The expiry sweep prints which files it moved to `archived/`. Then:

1. Remove the corresponding index lines from that directory's `MEMORY.md`
   (the file bodies are preserved in `archived/` — nothing is lost).
2. For any archived fact that is *still valid*, offer the user a promotion:
   restore it from `archived/` and re-save it as `tier: long` — through this
   gate, with their confirmation.
