02 // PRODUCTION SYSTEMS (private repositories)

SYSTEM ARCHITECTURE & SCOPE STACK
Multi-Agent Engineering Harness Parallel AI coding agents on isolated lanes across WezTerm. Cross-family review: the model family that writes a change does not approve it. Every commit passes cargo fmt, clippy::pedantic -D warnings, the test suite and a secret and personal-data scan before it lands. Rust · Git · WezTerm
Financial & OCR Reconciliation Engine Monthly sales packets, statement and receipt OCR, reconciled to the exact cent in i64 with zero floating-point drift; every number traces back to its source page. Rust · DataFusion · redb · OCR
Proven Money Lean 4 specification of the currency core: cents conserved across N-way splits, half-up rounding bounds, no i64 overflow. Machine-checked proofs underway; target year-end 2026. Lean 4 · Rust
Field Operations & Property Platform Rental property operations: work orders, labor-hour ledgers, receipts and expenses on embedded ACID transactional storage. Rust · redb

03 // DOCTRINE

01. MEASURE BEFORE CLAIMING   :: working code and a verified result are different states.
                                 done means it ran and was checked against ground truth.
02. ADVERSARIAL VERIFICATION  :: the model family that writes a change never approves it.
                                 compiler, lint and privacy gates fail closed.
03. ZERO-FLOAT LEDGERS        :: money is i64 integer cents, being proven in Lean 4.
                                 floating point is forbidden on financial paths.
04. SCAR-DRIVEN AUTOMATION    :: every bug becomes a regression test.
                                 every repeated failure becomes a permanent gate.
05. SHIP DAILY                :: small verified increments, every day, no unverified merges.
