# Memory Log - 2026-01-31

## Work Completed

### Smart Model Routing System
- **What:** Implemented cost-saving model routing — Sonnet as default, auto-escalate to Opus for complex work
- **Files changed:** AGENTS.md (added mandatory routing rules), model-routing-rules.md (standalone reference)
- **Impact:** ~3-4x more runway per weekly cycle by keeping 70%+ of interactions on Sonnet
- **Rule:** Every reply now tagged with `· sonnet` or `· opus` for transparency

### SongSense Product Architecture (Opus)
- **What:** Designed full product architecture for AI-powered music analysis app
- **User flow:** Upload/paste link → Processing with game → Review reveal with shareable link
- **Tech stack:** Next.js, BullMQ, Whisper API, songsee, Claude API, PostgreSQL, Redis
- **Monetization:** Free tier (3 songs/day), Pro ($9.99/mo unlimited), Enterprise
- **Cost per analysis:** ~$0.04-$0.15
- **MVP phases:** 4 weeks (landing page → processing pipeline → game → payments)
- **Jake's directive:** Build it with a team of paired agents (groups of 2) that push each other and double-check work
- **Status:** Architecture approved, awaiting agent team build

### Das Surya Album Review
- **New lyrics transcribed:** tracks 7-14 (dreamcatcher interlude, idk, with u, poor you poor me, wait 4 u, run to u, medications, hollow)
- **Full review written:** das-surya-review/REVIEW.md
- **Location:** das-surya-review/ (lyrics/, analysis/, mp3/, wav/)

### Burton Method Research Intel
- **Updated:** memory/burton-method-research-intel.md with major findings
- **Key findings:**
  - LSAC stealth-changed LSAT RC section (comparative reading no longer guaranteed)
  - 2026 admissions cycle exploding — applicants up 33%, applications up 27%
  - 7Sage launched full platform redesign (drill-first philosophy)
  - LSAT Demon and Blueprint fastest to react with content
  - AdeptLR spotted as new AI-adaptive LSAT competitor
  - Microsoft Study & Learn agent entering adaptive learning space

### Cron Jobs Ran Successfully
- Daily TLDR to #tldr channel
- EdTech intel scan (6 items posted, score 6+)
- Competitor digest (4 messages to #competitor-digest)
- Daily memory checkpoint (this file)

## Decisions Made
- **Sonnet as default model** — only escalate to Opus for complex architecture, deep research, creative work
- **Agent pairing strategy** for SongSense build — groups of 2 agents that double-check each other
- **SongSense game choice** — Start with Interactive Visualizer (easier, educational), add rhythm game later as premium
- **Label every reply** with model tag for cost tracking

## Next Steps
- **BUILD SONGSENSE** — Jake wants it built now with paired agent teams
- Spawn agent pairs to work on: frontend, backend/pipeline, game/visualizer, infrastructure
- Continue MCP ecosystem work (30 servers need testing, GitHub publishing)
- Iterate on MCP Animation Framework based on feedback
- Commit & push GHL-MCP submodule changes

## Notable Context for Future Me
- Jake is on an Opus 4.5 high — energy is UP, wants to build fast
- SongSense is the new hot project — full product with monetization potential
- Model routing is now a mandatory rule in AGENTS.md — enforce it
- Burton Method research found a major content opportunity (LSAT RC change) — competitors already publishing
- Das Surya review is complete with full lyrics and analysis
- Workspace has untracked files: das-surya-review/, model-routing-rules.md
