# Memory Dream

A read-only-by-default analyzer that flags issues in the shared memory store.
Mutating ops are gated behind `--apply-safe` (for low-risk fixes) or the
PROPOSED section (for judgment calls a human resolves by hand).

## The two-store model (important)

There are TWO separate memory stores on every machine:

- REPO store -- `.claude/memory/` (88+ `*.md` files + `MEMORY.md` index).
  Tracked in git, syncs to all machines via Gitea. **This is the source of
  truth.** `CLAUDE.md` mandates writing here.
- HARNESS PROFILE store -- `$HOME/.claude/projects/<slug>/memory/`. Machine
  local, NOT in git, NOT synced. This is the store the Claude Code harness
  auto-injects into the system prompt at session start.

The two drift over time. `memory-dream` reports that drift in its report
section. The companion script `.claude/scripts/sync-memory.sh` is what
actually reconciles them: it runs in **mirror mode** (since 2026-06-02) —
repo is authoritative, profile is synced to match (deletions propagate;
repo content wins on conflict). PROFILE-side hygiene lives in
`sync-memory.sh`, not here.

## What it checks

`scripts/memory_dream.py` runs six READ-ONLY analyses over the REPO store:

1. INDEX RECONCILE -- orphan files (no `MEMORY.md` line), index lines whose
   target file is missing, and frontmatter `name:` vs filename signals.
2. BACKLINKS -- `[[name]]` references in bodies whose target slug has no file.
3. REFERENCED-ARTIFACT VALIDITY -- conservatively extracts repo-relative file
   paths / script names from each body (backtick-wrapped single tokens only)
   and flags ones not found in the repo. Reported as **verify**, never delete
   (many are legitimately server-side or in sibling repos).
4. DUPLICATE / OVERLAP CLUSTERS -- groups memories by type + token-overlap /
   shared slug-prefix and lists candidate mergeable clusters (e.g. the many
   `feedback_syncro_*` files). **Proposes** merges; never performs them.
5. STALE DATED FACTS -- flags `project`-type memories with an "as of <date>"
   style claim older than ~6 months for re-verification.
6. DRIFT vs PROFILE STORE -- locates the harness profile memory dir for this
   project and reports profile-only files (candidates to migrate INTO the repo)
   and repo-only files (candidates to push OUT to profile). Report only.

The report ends with a `## PROPOSED (needs human approval)` section that is
NEVER auto-applied.

## Modes

- Default (no flag) -- **REPORT ONLY. Mutates nothing.** Writes a timestamped
  report to `.claude/memory/_reports/YYYY-MM-DD-HHMM-dream.md` (created if
  missing) and prints it to stdout.
- `--apply-safe` -- performs ONLY additive, non-destructive fixes and prints
  each action:
  - (a) append missing index lines to `MEMORY.md` for orphan files, under the
    correct `## <Type>` header, never reordering or removing existing lines;
  - (b) copy profile-only memory files INTO the repo store (additive
    migration). If a same-named repo file already exists it is SKIPPED and the
    conflict is reported -- it is never overwritten.
- `--no-file` -- print to stdout only; skip writing the `_reports/` file.
- `--report-file <path>` -- write the report to an explicit path.

### What dream does NOT auto-do

`memory-dream` does NOT, even with `--apply-safe`:

- delete a repo memory file (cluster dedup is a judgment call — pick which file becomes canonical, fold the others' content, retire the originals deliberately);
- remove or reorder index lines (index cleanups are also surfaced as proposals);
- overwrite a file whose content differs;
- perform a proposed merge.

These stay in the report's `## PROPOSED` section. The rationale isn't "never delete" any more (the fleet-wide additive safety net was dropped 2026-06-02; see `feedback_memory_sync_destructive_ok.md`) — it's that merges and dedups require human judgment about which file is canonical and how to combine content. Profile-side deletion DOES happen automatically — but in `sync-memory.sh`, not here.

### The operator MUST execute consolidations — do not just propose and leave

The script is additive-only **by design** (auto-merging would corrupt the store — see the trap below), but the SESSION running `/memory-dream` is NOT additive-only. **Executing the `## PROPOSED` consolidations is the expected work of a dream run, not a someday-maybe.** Parking proposals indefinitely is exactly what causes the fleet drift this skill exists to prevent. Each run, after reading the report:

1. **Triage every `[MERGE?]` cluster with judgment** (the detector is a coarse net):
   - **Intentional `X` + `X_history` (or `_archive`/`_detail`) splits are NOT duplicates** — current-state vs on-demand archive, cross-linked in frontmatter. Leave them. (The detector skips these as of 2026-06-11; older reports may still list them.)
   - **Topically-clustered but distinct facts** (e.g. several `reference_gitea_*`) — merge into one topic file ONLY if genuinely redundant or it reads better as one; otherwise leave.
   - **True duplicates / superseded files** — merge: pick the canonical file, fold in the others' unique content, `git rm` the retired ones, fix `MEMORY.md`.
2. **Deletions are first-class.** `git rm` of a retired memory is correct and propagates to every machine's profile store via `sync-memory.sh` mirror mode (repo authoritative). This is the fleet-consistency mechanism — use it.
3. **Commit + sync** so the consolidated store reaches the fleet.

If a cluster genuinely needs a decision you can't make, leave it AND say so explicitly in your summary — don't silently skip the whole PROPOSED section.

**The auto-merge trap (why the script stays additive):** blindly merging the detector's clusters destroys deliberate structure — verified 2026-06-11 when the flagged `project_*` / `project_*_history` pairs turned out to be intentional splits and the `gitea` / `syncro` clusters were distinct facts, not copies. Consolidation needs the operator's judgment; the script must never do it unattended.

## Running it

This machine's Python launcher is `py` (per identity.json); the script also
runs under `python` / `python3`. Stdlib only -- no pip deps.

```bash
# REPORT ONLY (default) -- writes _reports/<stamp>-dream.md and prints it
bash "$CLAUDETOOLS_ROOT/.claude/scripts/py.sh" "$CLAUDETOOLS_ROOT/.claude/skills/memory-dream/scripts/memory_dream.py"

# report to stdout only, write nothing
bash "$CLAUDETOOLS_ROOT/.claude/scripts/py.sh" "$CLAUDETOOLS_ROOT/.claude/skills/memory-dream/scripts/memory_dream.py" --no-file

# additive-only fixes (append orphan index lines, migrate profile-only files)
bash "$CLAUDETOOLS_ROOT/.claude/scripts/py.sh" "$CLAUDETOOLS_ROOT/.claude/skills/memory-dream/scripts/memory_dream.py" --apply-safe
```

`CLAUDETOOLS_ROOT` resolves from the env var, else `claudetools_root` in
`.claude/identity.json`, else the repo root derived from the script's own
location -- no hardcoded drive letters.

## Cleanup / approve workflow

1. Run with no flag. Read the report (stdout or `_reports/<stamp>-dream.md`).
2. Run `--apply-safe` to take the safe additive wins: orphan index lines get
   added, profile-only memories get migrated into the repo (conflicts skipped
   and reported).
3. Work the `## PROPOSED` section by hand:
   - `[MERGE?]` -- decide whether to consolidate a cluster. If yes, author a new
     combined memory (or set of files for a rule/history split), retire the
     originals via `git rm`, update `MEMORY.md`. Deletions are now first-class
     — `sync-memory.sh` mirror mode will propagate them to every profile store
     on the next run.
   - `[REVERIFY?]` -- confirm the dated fact still holds; update the body and
     its date if it changed.
   - `[STALE-REF?]` -- confirm the referenced path moved/renamed; repoint or
     annotate. Many are legitimately server-side (`.service` units, `/opt/...`).
   - `[INDEX-CLEANUP?]` / `[DRIFT-RESOLVE?]` -- human picks the winner.
4. Commit the repo store changes so they sync to the fleet via Gitea.

## Self-test

`scripts/selftest.py` runs the analyzer against a synthetic fixture memory
store in a temp dir and asserts each detector fires (orphan, missing target,
broken backlink, stale path, cluster, profile drift) and that `--apply-safe`
only touches the things it's supposed to (index appends + profile→repo copy
of new files; no deletions, no merges, no overwrites of differing content).
Run:

```bash
bash "$CLAUDETOOLS_ROOT/.claude/scripts/py.sh" "$CLAUDETOOLS_ROOT/.claude/skills/memory-dream/scripts/selftest.py"
```
