@@ -190,10 +190,10 @@ The following inconsistencies exist in the codebase:
 
 | Issue | Description |
 |---|---|
-| `pactBinding` upgrade | Referenced in `prestigeStore.doPrestige` but **not defined** in `PRESTIGE_DEF` constants |
-| UI vs store mismatch | UI displays `prestigeUpgrades.pactCapacity` but store logic checks `pactBinding` |
-| Pact persistence | `signedPacts` is persisted but also reset to `[]` on `startNewLoop` — pacts don't survive loops in current implementation |
-| `pactInterferenceMitigation` | Used in `pact-utils.ts` but no prestige upgrade defines it |
+| `pactBinding` upgrade | ✅ **RESOLVED** — Added to `PRESTIGE_DEF` in `prestige.ts` |
+| UI vs store mismatch | ✅ **RESOLVED** — `pactBinding` is now the canonical ID used everywhere |
+| Pact persistence | ✅ **RESOLVED BY DESIGN** — Pacts intentionally do NOT persist through prestige (reset each loop). This is the correct behavior per design intent. |
+| `pactInterferenceMitigation` | ✅ **RESOLVED** — Added to `PRESTIGE_DEF` in `prestige.ts`; `useGameDerived.ts` now passes it from prestige store |
