The private engine behind the tools here — a deterministic double-entry system for crypto and fiat where the ledger is derived from rules and raw events and regenerated rather than hand-edited, so every balance is reproducible and audit-grade. It's the deterministic half of the AI harness in my bio — the model reasons over messy evidence, this engine computes the books. FIFO cost basis, multi-chain event parsing, per-wallet provenance, multi-entity consolidation, price resolution, Australian CGT, and Xero integration on the fiat side. Its reconstruction core powers the per-collapse loss-quantifier sites below. Built because no existing tool could handle DeFi positions, collapsed exchanges, and SMSF compliance.

The model never touches the books. It proposes inputs — classified transactions, matched sources, entries extracted from messy evidence — and the deterministic engine regenerates the ledger from them: double-entry must balance, every figure traces to an event and a rule, and a wrong proposal is deleted and rebuilt, not patched (Claude Code plus domain skills). That is how non-deterministic AI reasoning coexists with a ledger that has to survive a tax audit. The same harness pattern, pointed at web development instead of accounting, built this site; the build log tells that story. Interactive demo coming: recorded agent traces replayed through a live in-browser eval scorer — no live LLM calls, by design.

A Meteora DLMM liquidity simulator: choose a price range of discrete bins, a distribution shape (spot / curve / bid-ask), and which side to fund, then scrub a seeded price walk. A generator derives per-bin liquidity, fee accrual, and impermanent loss vs HODL — regenerated from rules, never hand-edited, and reproducible from the seed.

A delta-neutral strategy simulator: feed strategy params and market data, and a generator derives the full trade ledger plus a scrubbable PnL timeline. Generator-first — the ledger is regenerated from rules, never hand-edited, and stays delta-neutral by construction.

A turn-based on-chain game where a bot plays automatically — each match emits a win/loss event, and the rewards/PnL ledger is derived from those events plus the payout rules (stake, payout multiple, protocol rake), regenerated rather than hand-edited. Generator-first, like the trade ledgers: every balance traces to a match outcome and a rule. Off-chain MVP now; same generator behind a Solana testnet program + event listener next.

The edge cases that silently break a normal crypto ledger — internal transfers between your own wallets, chain reorgs — reconcile correctly because the ledger is generated from raw events, not hand-posted. Minimal single-concept demos: phantom taxable gains vanish when self-transfers carry cost basis, and a hand-posted ledger diverges from a derived one the moment a confirmed tx is orphaned.

A hub of per-collapse loss quantifiers (FTX, Terra/LUNA, Celsius, …): a victim pastes a read-only public wallet address and the AccountMD engine reconstructs their history into a quantified AUD loss, then a CGT-ready evidence report — every figure sourced to an on-chain transaction. Read-only, address-only: no wallet connection, no signing. Programmatic-SEO, one landing page per collapse (Marc Lou playbook).
