Reorganize brain: projects/ top level, rename filenames, update homepage

- Moved everything from ideas/passepartout/ to projects/passepartout/
- Moved legal structures to projects/flags/
- Created missing _index.org files for all subdirectories
- Stripped redundant passepartout- prefix from filenames
- Rewrote root _index.org as generalized brain index (projects + concepts)
- Updated Hugo nav to Projects/Concepts
- Updated build script section descriptions
- Deleted stale ideas/passepartout-economics.md orphan

+#+title: Gate Rule Encoding from Codified Domains
+#+filetags: :passepartout:gates:rules:encoding:llm:translation:
+
+Laws, regulations, standards, procedures, and technical specifications are already written down in structured text. The LLM does not need to *reason* about them — it needs to *translate* them into gate rules and ACL2 theorems.
+
+Example: The US Federal Acquisition Regulation (FAR) is ~2,000 pages. A frontier LLM can ingest the FAR and produce a plist of gate rules:
+- (if contract > $250K AND not small-business-set-aside → :deny)
+- (if sole-source AND no justification-documented → :deny, produce-justification)
+
+ACL2 verifies the rule set for internal consistency. Screamer checks against existing compliance facts. The human reviews the bootstrap output and approves or corrects individual rules.
+
+The key distinction: the LLM is not *extracting knowledge from prose* — it is *translating a known rule system into a formal representation.* The result is not "the LLM's best guess" but "the rule set as stated in the source document, mechanically transcribed."
+
+For codified domains, the encoding cost drops from weeks to hours. The only bottleneck is human review of the 5% ambiguous rules. This is what makes the [[id:efc76898-03f7-57ba-923d-35d65da88bb7][sufficiency flip]] economically viable — once gates are encoded, verification is near-free. The resulting rules are packaged into [[id:c34940cc-090e-57c4-8020-e78b1d32b96c][domain gate packages]] that can be reused across deployments.
