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

+
+**Likely patentable:**
+- Probabilistic-deterministic split with deterministic gates between LLM proposal and execution (vs every competitor using prompt-based guardrails)
+- Foveal-peripheral context model with Org-tree structured retrieval (targets 2,000-4,000 tokens)
+- Merkle-tree memory with copy-on-write snapshots and operation-level undo/redo
+- Gate-to-fact bootstrap with sufficiency criterion (mechanically extracting facts from gate stack data structures)
+- Macro-layer-as-skill bootstrapping architecture (theorem-proving as hot-reloadable skills)
+
+**Likely not patentable (known techniques):**
+- ACL2 itself (decades old)
+- Screamer for consistency checking (obvious application)
+- Hot-reloadable skills (40 years old)
+- Org-mode as a data format
+
+**Strongest single claim:** The specific combination of probabilistic model + deterministic zero-token safety gates + Merkle memory + symbolic engine with sufficiency criterion. Each element is known; the combination is novel and non-obvious.
+
+**Counterargument:** A patent examiner will argue these are standard OS microkernel architecture, locality of reference, content-addressed storage, and capability-based security applied to an AI agent. The defense: they have never been *combined* in an AI agent, producing emergent effects no single principle produces.
