# Cognitive Memory Systemd Timers

Reference copies of the systemd user units that automate memory maintenance.

## Services

| Unit | Schedule | What it does |
|------|----------|-------------|
| `cognitive-memory-daily` | daily | Decay scores, regenerate CORE.md, git sync — for ALL graphs |
| `cognitive-memory-embed` | hourly | Refresh embeddings (skips if unchanged) — for ALL graphs |
| `cognitive-memory-weekly` | weekly | Run reflection cycle — for ALL graphs |

All three services now call `scripts/maintain-all-graphs.sh` instead of
individual `claude-memory` commands.  The script discovers every graph via
`claude-memory graphs` (default graph + named graphs under
`~/.local/share/cognitive-memory-graphs/`) and runs the appropriate command
for each one, passing `--graph <name>` for non-default graphs.

Named graph directories that do not exist on disk are silently skipped.

## Scripts

| Script | Purpose |
|--------|---------|
| `scripts/maintain-all-graphs.sh` | Loop decay/core/embed/reflect over all graphs |
| `scripts/memory-git-sync.sh` | Git commit+push for default graph and all named git repos |

## Install / Update

```bash
# Copy units into place (adjust source path to your cognitive-memory install)
CMDIR=~/.claude/skills/cognitive-memory  # or /mnt/NV2/Development/cognitive-memory
cp "$CMDIR"/systemd/*.service "$CMDIR"/systemd/*.timer \
   ~/.config/systemd/user/

# Reload and enable
systemctl --user daemon-reload
systemctl --user enable --now cognitive-memory-daily.timer
systemctl --user enable --now cognitive-memory-embed.timer
systemctl --user enable --now cognitive-memory-weekly.timer
```

## Verify

```bash
systemctl --user list-timers 'cognitive-memory-*'
systemctl --user start cognitive-memory-daily.service  # manual test run
journalctl --user -u cognitive-memory-daily.service --since today
```

## Manual test (single graph)

```bash
# Default graph only
claude-memory decay && claude-memory core

# Named graph
claude-memory --graph paper-dynasty decay && claude-memory --graph paper-dynasty core

# All graphs at once (adjust path to your install)
/path/to/cognitive-memory/scripts/maintain-all-graphs.sh --daily
```
