 ** Projects
 
 - [[id:1c3ec48b-446c-50d2-b53e-126a81f5143f][Passepartout]] — a verifiable personal intelligence: self-bootstrapping Lisp machine, gate-verified reasoning, social protocol. Architecture, staged roadmap, strategy, competitive analysis, compliance landscape.
 - [[id:1e5f6a7b-8c9d-0e1f-2a3b-4c5d6e7f8a9b][Flags]] — legal structures: entity types, jurisdictional analysis, asset protection, practical setup guides.
 
-** Concepts
+** Ideas and concepts
 
-- [[id:85f963a7-a10f-45cc-ace6-6edfeefee762][Lisp, Provers, and vs Rust]] — Lisp vs Rust analysis, prover architecture, HOL bootstrap, comparison with Lean.
-- [[id:dddd52a7-adb8-470e-a459-614ade5f76af][Closing the Lisp Gap]] — performance and ecosystem gaps between Lisp and C/Rust, and how Passepartout closes them.
-- [[id:be9bccc7-5adf-4d0d-8ee4-8855892189bf][Neurosymbolic Loop Architectures]] — how neurosymbolic systems loop between symbolic reasoning and neural learning.
-- [[id:d2722576-fc9b-4bd3-bc2f-f5692b561b4e][Who Is Closest to Passepartout?]] — nearest-neighbor analysis of related projects.
