# Replay (Counterfactual) This skill spawns a parallel "what-if" timeline rooted at an existing `mem_snapshots` row. It does **not** modify `mem_nodes`, `mem_bt_ratings`, or `mem_judgements`. The branch is recorded in `mem_replay_branches` and surfaced in the cockpit's `Replay` tab. ## When to invoke - The user types `/replay`. - The cockpit shows a `branch_paused` event the user disagrees with — replay lets them simulate the alternative path before deciding whether to call `mcp__memory__resume_branch`. - Post-mortem after a missed preregistration: replay against the snapshot from before the prereg lock to inspect what the alternative hypothesis would have looked like. ## Workflow 1. Pick the snapshot. If the user did not name one, list recent snapshots via the cockpit (snapshots are also visible from `mcp__memory__snapshot` outputs in earlier turns). 2. Phrase the counterfactual in one sentence. Examples: - `"Approve hyp_07 instead of pruning it"` - `"Tighten preregistration alpha to 0.01 instead of 0.05"` - `"Use seed budget 10 instead of 3 for hyp_03"` 3. Call `mcp__memory__replay_counterfactual(snapshot_id, counterfactual)`. Capture the returned `branch_id`. 4. Run any inspection / hypothetical analysis you need INSIDE the response (no Bash, no file writes). All conclusions must reference the `branch_id` so the cockpit can group them. 5. If the replay produces an actionable suggestion, write it as a `cockpit_interventions` row (kind=`note`) so the user can p
