 ## Implementation Plan
 
-1. Update `src/shared/math/RandomSeed.js` to reuse `randomHelpers.js` for procedural helper methods.
-2. Keep the existing seeded `next()` algorithm unchanged.
-3. Add state save/restore methods.
-4. Extend `tests/shared/RandomSeed.test.mjs` with sequence compatibility, new method, and state tests.
+1. Add `src/shared/validation/assert.js` with only the required generic assertion helpers.
+2. Remove duplicated generic assertions from `src/shared/math/randomHelpers.js`.
+3. Import the shared assertions from `randomHelpers.js`.
+4. Run targeted random helper, `Random`, and `RandomSeed` tests.
 5. Produce required PR reports and repo-structured ZIP.
 
 ## Acceptance Criteria
 
-- Existing seeded sequence values remain compatible.
-- Same seed and reseeding behavior remain deterministic.
-- New procedural methods use the same seeded random stream.
-- State save/restore resumes the sequence from the saved point.
+- Existing random helper behavior is preserved.
+- Existing `Random` and `RandomSeed` behavior is preserved.
+- Public random APIs are unchanged.
+- Shared assertion module stays limited to the current reusable validation helpers.

+- Updated `randomHelpers.js` to import those assertions from the shared validation module.
+- Preserved existing `Random`, `RandomSeed`, and random helper behavior.
+- Did not change public API.
+- Did not add unrelated validation helpers.
+- No UI, API, database, or unrelated cleanup changes were made.
+
+## Branch Validation
