+---
+
+# Resolving `beads.jsonl` Merge Conflicts
+
+If you encounter a merge conflict in `.beads/beads.jsonl` that doesn't have standard git conflict markers (or if `bd merge` failed automatically), follow this procedure.
+
+## 1. Identify the Conflict
+Check if `beads.jsonl` is in conflict:
+```powershell
+git status
+```
+
+## 2. Extract the 3 Versions
+Git stores three versions of conflicted files in its index:
+1. Base (common ancestor)
+2. Ours (current branch)
+3. Theirs (incoming branch)
+
+Extract them to temporary files:
+```powershell
+git show :1:.beads/beads.jsonl > beads.base.jsonl
+git show :2:.beads/beads.jsonl > beads.ours.jsonl
+git show :3:.beads/beads.jsonl > beads.theirs.jsonl
+```
+
+## 3. Run `bd merge` Manually
+Run the `bd merge` tool manually with the `--debug` flag to see what's happening.
+Syntax: `bd merge <output> <base> <ours> <theirs>`
+
+```powershell
+bd merge beads.merged.jsonl beads.base.jsonl beads.ours.jsonl beads.theirs.jsonl --debug
+```
+
+## 4. Verify the Result
+Check the output of the command.
+- **Exit Code 0**: Success. `beads.merged.jsonl` contains the clean merge.
+- **Exit Code 1**: Conflicts remain. `beads.merged.jsonl` will contain conflict markers. You must edit it manually to resolve them.
+
+Optionally, verify the content (e.g., check for missing IDs if you suspect data loss).
+
+## 5. Apply the Merge
+Overwrite the conflicted file with the resolved version:
+```powershell
+cp beads.merged.jsonl .beads/beads.jsonl
+```
+
+## 6. Cleanup and Continue
+Stage the resolved file and continue the merge:
+```powershell
+git add .beads/beads.jsonl
+git merge --continue
+```
+
+## 7. Cleanup Temporary Files
+```powershell
+rm beads.base.jsonl beads.ours.jsonl beads.theirs.jsonl beads.merged.jsonl
+```
