+**Base:** `origin/main`  
+**Follow-up:** Alignment register E7.M2 References column repaired; negative CI spot-checks run (see Verification).
 
 ## Verdict
 
-**Request changes** — one documentation corruption in the alignment register (blocking); implementation otherwise matches plan.

 ## Blocking issues
 
-1. **Corrupted E7.M2 row in `documentation_and_implementation_alignment.md`** — line 62 ends the References column with a stray fragment:
-
-   ```
-   … [NEO-43](../../plans/NEO-43-implementation-plan.md) |ion-plan.md), label **`E7.M2`** on NEO-124–NEO-132 |
-   ```
-
-   This breaks the markdown table and truncates the intended link list. Replace with a single clean References cell, e.g.:
-
-   ```
-   | [E7M2-prototype-backlog.md](../../plans/E7M2-prototype-backlog.md), [E7_M2](E7_M2_RewardAndUnlockRouter.md), [NEO-124](../../plans/NEO-124-implementation-plan.md), [NEO-43](../../plans/NEO-43-implementation-plan.md), label **`E7.M2`** on NEO-124–NEO-132 |

 ## Suggestions
 
-1. **Spot-check negative CI paths before merge** — Plan lists manual failure cases; run at least one each (typo `itemId`, wrong XP amount, skill missing `mission_reward`) to confirm gate messages are actionable. Not required for approve once doc fix lands, but cheap confidence.
+1. ~~**Spot-check negative CI paths before merge** — Plan lists manual failure cases; run at least one each (typo `itemId`, wrong XP amount, skill missing `mission_reward`) to confirm gate messages are actionable.~~ **Done.** Ran three temporary mutations (restored after each): operator chain item typo → freeze gate exit 1; gather intro amount **24** → freeze gate exit 1; salvage without `mission_reward` → allowlist cross-ref exit 1. Note: item typo is caught by freeze gate before item cross-ref (gate order: presence → freeze → cross-ref).
 
 2. **NEO-125 sync comment** — `PROTOTYPE_E7M2_COMPLETION_BUNDLES` already points at E7.M2 freeze; when server loader lands, mirror the constant in C# with an explicit cross-link comment (plan risk row already tracks this).
