# Ralph Specum Cancel Use this to stop execution safely and optionally remove a spec. Safe cancel preserves the spec and every prototype source path. Derive `RALPH_CODEX_PLUGIN_ROOT` from this loaded skill by resolving two parent directories from the `SKILL.md` directory. Never derive it from the project working directory. ## Contract - Resolve the target by explicit path, exact name, or `.current-spec` - Treat a missing `activePrototypes` field as an empty map - Publish reviewed immutable cancellation evidence before removing active state - Confirm the exact local target before any deletion - Never delete a remote branch or perform another remote action - Do not guess on ambiguous names ## Action 1. Resolve the target spec. If none exists, report that there is nothing to cancel. 2. Read `.ralph-state.json` when present and summarize the current phase and progress. 3. If `activePrototypes` is non-empty, use the resolved `basePath` and run `"$RALPH_CODEX_PLUGIN_ROOT/scripts/prototype_records.py" reconcile` before cancellation. Process active IDs by `created`, then ID, at the next safe tool boundary. 4. For each active prototype: - Inspect its `owner`, `leaseToken`, and `harnessRun.id`. When `owner` and `leaseToken` are both null or absent, verify that `harnessRun.id` is also null or absent and no builder is associated, then skip interrupt and release and continue cancellation. If those fields disagree, treat the entry as inconsistent builder ownership: retain the leas...
