+# Sprint 188 Plan: Replay and Rollback Enforcement I
+
+## Context
+Replay/rollback metadata is emitted but not fully enforced.
+
+## Goals
+1. Enforce replay contract presence at queue time
+2. Enforce rollback contract presence at validation time
+3. Emit explicit deterministic blockers
+
+## Steps
+
+### Step 1979: Queue replay-contract enforcement (10 tests)
+Block tasks missing required replay fields in strict mode.
+
+### Step 1980: Validation rollback-contract enforcement (10 tests)
+Fail validation when rollback contract fields are missing.
+
+### Step 1981: Deterministic blocker taxonomy extension (8 tests)
+Add `missing_replay_contract` and `missing_rollback_contract` classes.
+
+### Step 1982: Contract enforcement telemetry (8 tests)
+Emit aggregate counts and per-task diagnostics.
+
+### Step 1983: Sprint 188 Integration Summary (8 tests)
+Add `editor/src/Sprint188IntegrationSummary.h`.
+
+## Architecture Gate
+- Strict mode cannot report ready when replay/rollback contracts are absent.
