+# Goal: Max Index V1
+
+Phase 0 is complete. Before executing the next phase, run a task-level PRE
+review for that phase, update `docs/goals/max-index-v1/PLAN.md`, then use
+Krypton Execution for the approved slice.
+
+Core rules:
+
+- Treat `PLAN.md` as the source plan.
+- Execute only the next PRE-approved phase; do not batch later phases.
+- Preserve intent, ownership, contract, cutover, evidence, and kill criteria.
+- Do not add a new dominant path without deleting, redirecting, demoting, or shimming the displaced path.
+- Capture acceptance evidence from the target perspective.
+- Say "implemented but unproven" if that evidence cannot be captured.
