Source and target databases do not share a company id. Pass

Error message

Source and target databases do not share a company id. Pass --company explicitly once both sides match.

What it means

Thrown by resolveMergeCompany when no --company selector was given and the source and target databases share ZERO company ids. Merge-history copies issues for one company across both DBs, so without any common company id there is nothing to merge. This typically indicates the target was seeded from a different source, or the companies were created independently with different ids.

Solutions

1. Re-seed the target from the intended source so company ids match: `paperclipai worktree:seed --from-config <source>`.
2. Create the same company (same id) in the target before merging.
3. Confirm you are pointing merge-history at the correct source and target endpoints.

Example fix

// before: no shared company id between source and target
// after
paperclipai worktree:seed --from-config /correct-source/.paperclip/config.json
paperclipai worktree:merge-history

const shared = sourceCompanies.filter((c) => targetById.has(c.id));
if (shared.length === 0) throw new Error("No shared company id; re-seed target from source");

function hasSharedCompany(source: {id:string}[], target: {id:string}[]): boolean {
  const tids = new Set(target.map((c) => c.id));
  return source.some((c) => tids.has(c.id));
}

When it happens

Trigger: Target worktree seeded from source A but merge attempted against source B; target created fresh (empty/minimal) so it has no companies yet; company ids diverged after independent creation.

Common situations: Cross-merging two unrelated Paperclip instances; target DB reset after seeding; company created in source after the seed snapshot was taken.
