⚡TOLTOL: Rename Joker→three chains, fix phi notation, clarify GaNS baseline
🧲ZULZUL: Build model progression 1→2→3→4→5 showing entrepreneur's promise evolution
→ $/time test:
Deliver? Clear progression × Bayesian framework = ✓
Sell? OM professors × Promise-precision tradeoff = ✓
**Learning**: External clarity (naming, notation) enables internal rigor (model logic)
## TODO from Charlie Meeting:
1. **Immediate fixes** (âš¡toltol):
- [ ] Change "Joker diagram" → "three chains diagram"
- [ ] Fix notation: phi (not five) throughout
- [ ] Remove beta distribution from abstract
2. **Deep work** (🧲zulzul):
- [ ] Map GaNS model clearly as baseline (model 1)
- [ ] Articulate why each model progression matters
- [ ] Solve for optimal μ* in model 3
- [ ] Add convex d(φ) analysis for model 3b
3. **Paper structure**:
- [ ] Crystal-clear introduction BEFORE literature review
- [ ] Each model shows: entrepreneur chooses → affects outcomes
- [ ] Model 1: No choice (p,V exogenous)
- [ ] Model 2: Choose φ (cheap talk)
- [ ] Model 3: Trade-off sell vs deliver
- [ ] Model 4: Choose μ,τ (precision matters)
- [ ] Model 5: Precision has cost c·ln(τ)
