Task 07: excludeDuplicateComments — правило не применяется

Assigned to: Antigravity (Implementation Orchestrator)
Priority: MEDIUM (audit-trail accuracy)

Base SHA: 8741569817f4463387c5dc3ac36c0beaedbd0663

Scope

1. Semantic decision on duplicate comments:
   • Randomayzer core algorithm HMAC_SHA256_FY_V1 and executeDeterministicDrawV1 operate on a 1-participant = 1-chance model (AGENTS.md §1 forbids altering deterministic randomizer/draw algorithms without explicit owner task).
   • Multi-weight/multi-entry draws would require modifying the deterministic randomizer and snapshot data structures, which is out of scope.
   • Therefore, choose Option B: Unconditional deduplication.
2. Backward compatibility & Conditions Hash versioning:
   • Ensure computeConditionsHash handles backward compatibility: snapshots created in legacy format (containing excludeDuplicateComments) must continue to verify verified: true with identical hash values (conditionsIntegrity: true).
3. Fix duplicate merging in filter-engine.ts:
   • Fix commentsCount summing so that duplicates with commentsCount: 0 (or undefined) do not artificially add + 1.
4. Update UI and validation schemas if excludeDuplicateComments is removed or deprecated:
   • Clean up or deprecate gracefully in DEFAULT_FILTER_RULES, filterRulesSchema, src/app/giveaways/new/page.tsx.
5. Create regression tests tests/duplicate-comments-rule.test.ts:
   • Duplicate with commentsCount: 0 does not add 1.
   • Legacy snapshots with excludeDuplicateComments in filterRulesSnapshot retain verified: true and match original conditionsHash.
   • Filter engine deduplication behaves deterministically.
6. Verify and output report to agents/antigravity/done/TASK-2026-08-21-07-duplicate-comments-rule.md.
