PROJECT ARCHIVE — 6 ENTRIES
Selected systems, experiments and tools.
Three works carried far enough to show in full, and the working archive behind them.
01 / HALF-LIFE
Whatremains?
38 mg remaining
An iOS app that models caffeine in the body as first-order decay and reads it against real sleep timing. HealthKit access only ever feeds suggestions — it never silently overwrites a time you set yourself, and raw sleep samples are never synced off the device.
- Build
- 1.0.4 (6) — signed archive exported
- Health data
- Apple HealthKit
- Model
- A(t) = A₀ · e^(−λt)
- Decay API
- Python · live endpoint
02 / FABTWIN
Processunder control.
A plasma-etch SPC and fault-detection simulator. The differentiator is not the model — it is validating that model against two real public fab datasets with the correct statistics, including a deliberate reproduction of the common evaluation mistakes as a documented contrast.
- Status
- IN PROGRESS
- Build
- 42/42 unit tests — local + CI, ruff/mypy clean
- Datasets
- SECOM · LAM9600 (public fab data)
FabTwin lives in the Lab as entry L-03 — it is an experiment under validation, not a shipped project, and its record stays there.
03 / LEOLOGIC OS
Systemsfor one.
A personal operating system for tasks, priorities, and agent workflows, with Obsidian as the knowledge layer beside it rather than duplicated inside it. The split is a documented scope boundary — neither system repeats what the other already does well.
- Phases shipped
- Phase 1–9 + Adventure Mode (A–C)
- Client stack
- Vite + React + TypeScript + Vitest
- Usage evidence
- Real daily/ and weekly/ review files
02 / ARCHIVE — 3 ENTRIES
Project registry.
Everything else on the record. Live system entries are wired to real APIs; architecture only entries are private or conceptual, with the execution stack documented in full.
A remote operator console for Interactive Brokers, built as a private Discord bot — market data, signals, and backtests all run from a chat command, not a web dashboard. Live order execution is gated off behind measurable validation criteria. Intentionally paused since May 2026 while execution priority sits with Half-Life and LeoLogic OS; reactivation requires a runtime evidence refresh before any further build work.
Parked — idle since 2026-05 · Architecture only · Python / Discord Bot / IBKR API
An evidence-driven AI system for engineering drawings — upload a PDF, extract objects and relationships with traceable source regions, and get grounded Q&A that highlights back to the exact area of the drawing it answered from.
In Development · Architecture only · TypeScript / Cloudflare Workers / D1
A local-first iOS app for running one bounded, reviewable personal experiment at a time — caffeine cutoffs, screen wind-down, morning light — reporting results with honest confidence caveats instead of manufactured causal claims.
In Development · Architecture only · Expo / React Native / TypeScript
