Three different jobs, often confused

Use Veripsa alongside your worktrees, merge queue, and AI reviewer

These tools answer different questions, so they stack rather than replace each other.

1. Step 1

   Veripsa surfaces the conflict

   While PRs are still open, Veripsa Core flags overlap across content-free change metadata — so reviewers can discuss landing order before review even finishes.

2. Step 2

   Your worktrees or agent runner isolate the working copies

   Git worktrees — and the agent runners built on them — give each agent its own checkout so they don't overwrite each other on disk. They don't watch the open PRs, so two agents can still open PRs that each pass alone and break main together. That gap is the one Veripsa watches.

3. Step 3

   Your merge queue serializes the merge

   When the chosen PR is approved, the merge queue serializes the merge step and re-runs CI in order. Veripsa does not replace that — it sits earlier in the lifecycle.

4. Step 4

   Your AI reviewer comments on the code

   An AI reviewer can still comment on quality, bugs, and style inside the PR. Veripsa stores content-free operational metadata, not file bodies, and never comments on code quality.

5. Step 5

   Copilot fixes the conflict Git already sees

   GitHub Copilot's conflict resolution — the Fix with Copilot button or an @copilot mention — starts after a PR already reports a merge conflict, and fixes that one PR. Veripsa's signal comes earlier, while both PRs are still open and the landing order is still a choice. The two solve problems at different moments, so they stack: take the landing order from Veripsa, and when a textual conflict still happens, let Copilot resolve it.
