…experimentation Proposes four additive capabilities for the pi.ruv.io brain: 1. Hypothesis generation via Gemini 2.5 Flash on cross-domain edges 2. Quality scoring via DiskANN + PageRank (ForwardPush sublinear) 3. Noise filtering (ingestion gate + meta-mincut on knowledge graph) 4. Self-improvement tracking (50-query benchmark suite + auto-rollback) All feature-gated. No changes to running brain. Separate Cloud Run service for hypothesis engine. DiskANN is fallback-only (HNSW stays primary <50K). 5-week phased implementation. ~$0.03/day Gemini cost. Co-Authored-By: claude-flow <ruv@ruv.net>
The daily digest was showing 10 identical "Self-reflection: training cycle" debug entries. Now: 1. Filters out debug category memories entirely 2. Filters known noise patterns (training cycles, IEEE events, DailyMed) 3. Skips content < 50 chars (scraping artifacts) 4. Category emojis for visual scanning 5. Cleaner layout with sentence-boundary truncation 6. Better subject line: "[pi brain] 5 new discoveries today" 7. Updated header: "What the Brain Learned Today" 8. Filters auto-generated tags from display Co-Authored-By: claude-flow <ruv@ruv.net>
Gist publishing was never firing because thresholds were too aggressive (set when brain had 3K memories; now has 10K+): - MIN_NEW_INFERENCES: 10 → 3 - MIN_EVIDENCE: 1000 → 100 - MIN_STRANGE_LOOP_SCORE: 0.1 → 0.01 - MIN_PROPOSITIONS: 20 → 5 - MIN_PARETO_GROWTH: 3 → 1 - MIN_INFERENCE_CONFIDENCE: 0.70 → 0.60 - MIN_UNIQUE_CATEGORIES: 4 → 2 - strong_inferences: >= 3 → >= 1 - strong_propositions: >= 5 → >= 2 - min_interval: 3 days → 1 day Daily email improvements: - Filter debug/training-cycle entries from digest - Filter known noise patterns (IEEE events, DailyMed, etc.) - Skip content < 50 chars (scraping artifacts) - Category emojis for visual scanning - Cleaner subject: "[pi brain] N new discoveries today" - Better header: "What the Brain Learned Today" - Sentence-boundary truncation for content previews - System font instead of monospace for readability Co-Authored-By: claude-flow <ruv@ruv.net>

Summary
Three changes to make the pi.ruv.io brain autonomously discover and publish:
1. Gist Publishing Thresholds Tuned
The brain's Gist publisher (
gist.rs) was never firing because thresholds were set for a 3K-memory brain (now 10K+). Relaxed all thresholds to enable ~1 gist/day of genuine discoveries. The 3-pass Gemini pipeline (Google Search grounding → brain memory search → synthesis) is already implemented — it just needed the gate opened.2. Daily Email Improved
The digest was showing 10 identical "Self-reflection: training cycle" debug entries. Now filters noise (debug category, training cycles, IEEE events, short content), adds category emojis, better subject lines, sentence-boundary truncation.
3. ADR-148: Brain Hypothesis Engine
