description: Sync decision graph with teammates - pull events, rebuild, push

# Multi-User Sync
The shared decision graph lives in `.deciduous/sync/` as one JSON file per node, edge, theme, and tag. Your SQLite database is a private cache of it. `deciduous sync` makes the two agree, in both directions.
## Step 1: Pull
```bash
git pull --rebase
```
## Step 2: Sync
```bash
deciduous sync
```
This creates `.deciduous/sync/` if needed, imports the pre-0.17 JSONL event log once, imports records you do not have (teammates' nodes get *local* ids here), exports database rows that have no record yet, and regenerates `docs/graph-data.json`. "Pending" edges are waiting for a node that has not been pulled yet.
## Step 3: Link across users if needed
Local ids differ per machine. Refer to a teammate's node by the change_id prefix shown in the CHANGE column:
```bash
deciduous nodes
deciduous link a1b2c3d4 42 -r "our action implements their goal"
```
## Step 4: Commit and push
```bash
git add .deciduous/sync/ docs/graph-data.json docs/git-history.json
git commit -m "graph: <what was decided>"
git push
```
`deciduous sync --check` exits non-zero if anything is still pending, so it works as a pre-push guard.
## Merge conflicts
- **A file under `.deciduous/sync/`**: two people edited the same record. Normally git merges it field by field through the `deciduous` merge driver, so you never see this. If a file has `<<<<<<<` markers, run `deciduous sync`: it merges the sides the same way and imports the result.
- **`docs/graph-data.json`**: never hand-merge it. Take either side and run `deciduous sync` to regenerate.
## Troubleshooting
| Teammate's nodes missing | `git pull` then `deciduous sync` |
| "No node has a change_id starting with ..." | You have not synced their record yet |
| Record file unreadable | `git checkout -- <file>` or fix the JSON; sync skips it and continues |
| `.deciduous/sync/` not in git | `deciduous update` fixes `.gitignore` |
