- Implement `getModerationInfoForAuthors` in `ModerationService` for batching. - Extract utility functions to `js/services/moderationUtils.js` to reduce `ModerationService` size. - Update `createModerationStage` to use batch lookup, reducing sequential overhead. - Benchmarks show ~50% improvement (454ms -> 227ms) for 5000 items. - All unit tests pass. - Task log: `docs/agents/task-logs/weekly/2026-02-22_01-25-01_perf-optimization-agent_completed.md` Co-authored-by: PR0M3TH3AN <[email protected]>

Weekly Perf Optimization Agent - Completed
Agent: perf-optimization-agent Date: 2026-02-22 Cadence: Weekly
Summary
Executed a performance optimization on the Moderation Stage in the feed engine.
Tasks
- Diagnosis: Identified that
moderationStagewas performing sequential moderation lookups for each item in the feed, causing repeated calls togetActiveTrustedMutersForAuthorand potentially expensive pruning checks. - Benchmarking: Created
benchmarks/moderation_batch_bench.jsto simulate feed processing.- Baseline: ~454ms for 5000 items (500 authors).
- Optimization:
- Refactored
js/services/moderationService.jsto extract static utilities tojs/services/moderationUtils.js(reducing file size and complexity). - Implemented
getModerationInfoForAuthors(authors)inModerationServiceto batch author lookups and prune aggregates in a single pass. - Updated
js/feedEngine/stages.jsto usegetModerationInfoForAuthorsfor batch retrieval.
- Refactored
- Verification:
- Re-ran benchmarks: ~227ms average (~50% improvement).
- Verified logic with
npm run test:unit. - Lint checks passed (resolved file size growth by extraction).
