Hermes 9b2be10c77 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

The Self-Driving Lisp Machine

A Tenstorrent P150 (~72 RISC-V Tensix cores) running Passepartout: 72 RISC-V cores running Lisp microcode, one core dedicated to ACL2, one to Screamer, the rest to gate verification and fact store operations.

The self-driving threshold: the system can synthesize and load its own FPGA microcode or Tensix dispatch programs from within the running Lisp image. The system profiles its own gate verification latency, proposes a new microcoded instruction for the hot path, compiles RISC-V assembly from ACL2-verified specifications, loads it via PCIe DMA from within SBCL, benchmarks it — and rolls back if slower.

Every subdomain involved is software — the most codifiable domain. RISC-V ISA, SBCL internals, ACL2 metafunctions, CIC type theory, compiler optimization — all can flip to symbolic sufficiency within days to weeks of ingestion.

Timeline: ~6,000 lines of new code (microcode, PCIe DMA, Tensix management, benchmark harness). ~60 cycles at current velocity. 2-4 weeks. Total from today: 6-10 weeks.

The Tenstorrent approach is dramatically simpler than FPGA because the microcode is RISC-V assembly (software), not FPGA bitstream (hardware with minutes-per-iteration synthesis).
