Restructure economics doc into 27 org-roam interlinked nodes

Replace monolithic passepartout-economics.org with directory of
org-roam style nodes, each with :ID: property and cross-references
using [[id:uuid][title]] format.

27 nodes organized by theme:
- Core: index, triad overview, agora, stoa
- Revenue: verification appliance, domain gate packages, evaluation
  harness, skill marketplace, agora usernames, PDS service, compute marketplace
- Strategy: investment thesis, moats, licensing, patents, AI industry impact
- Analysis: lisp economics, sufficiency flip, time estimates, cost structure,
  gate rule encoding, upgrade lifecycle, biology parallels, symbolics comparison
- Big money: verification monopoly, infrastructure lock-in

+#+title: Domain Gate Rule Subscriptions
+#+filetags: :passepartout:revenue:gate-rules:compliance:subscription:
+
+Pre-verified gate rule packages for specific compliance domains. Translated from published regulations by the LLM, verified by ACL2, reviewed by a human for the 5% ambiguous edge cases.
+
+- HIPAA package: $50K/yr
+- SOC2 package: $50K/yr
+- GDPR package: $50K/yr
+- FedRAMP package: $100K/yr
+- Combined enterprise: $250K/yr
+
+Switching costs are high — changing packages means re-verifying the fact store against new rules. The infrastructure lock-in compounds: a hospital at $250K/yr in year one grows to $500K-$1M by year five as more packages are added and the fact store becomes more valuable than the software itself.
+
+20 subscriptions in year one = $1M-$5M.
