fix(economics): address 17 PR review comments on #114

Blocking fixes:
- V-13: legal_services demand_model compliance→market (build-breaker)
- D-184: political flag names match TOML (commission_certified etc.)
- D-184: professional services list matches TOML
- D-173: elasticity count 5→4, cross-ref to D-184
- Workshop outcomes: fix self-contradicting fusion fuel statement
- R-011: move to end of file (was between D-183 and D-184)

Should-fix:
- D-166 domain link scope.md→architecture.md
- Sprint briefing counts updated (13→17 D-records, #801 marked done)
- Burnelli-Sheldon added to agent roster + briefing created
- questions-architecture.md footer tally updated
- medical_services demand_model utility→market
- timber display name drop "/Biomass"

Polish:
- D-171 Groombridge clarified (clearing house, not co-issuer)
- hospitality description has Reach texture
- commission_certification shadow_viable=false rationale in description
- Ticket #801 description updated
- Wiki pages regenerated

+## Current Project State
+See [PROJECT_STATE.md](../../PROJECT_STATE.md) for shared project state (cascade phase, sprint, decision count).
+
+## Your Domain
+
+Economics simulation: commodity pricing, Leontief production chains, spatial price equilibrium (damped tâtonnement), corporate behavioral agents, stability criteria.
+
+## Key Decisions You Own or Contributed To
+
+- **D-173** Commodity taxonomy (co-author with Gestalt)
+- **D-178** Economic model architecture (primary author — 3-layer model)
+- **D-179** Stability acceptance criteria (primary author — 4 tests)
+- **D-184** Commodity catalog, 36 types (co-author — pricing, margins, cascades)
+- **D-185** Brands are not commodities (validated economic separation)
+- **D-187** Fusion fuel as intermediate, 8:1 yield (validated economics)

+## Open Work
+
+- Brand-layer demand interface design (#811)
+- Tâtonnement parameter tuning (α=0.03, β=0.4 from D-178 — needs validation against D-179 stability criteria)
+- Energy-over-gate demand reduction coefficient (~0.3× utility — needs calibration)
