The archive drawer.
Deep-dive system notes — architecture, decisions, tradeoffs, and what actually broke. Written for people who like the machinery.
SmartInvoiceExtractor
Regex extracts high-confidence fields from pdfplumber-parsed PDFs; Gemini fills gaps when critical fields are absent. A quality gate, JSON normalisation layer, and regex suggestion loop keep the LLM call rate low and the patterns improving. Production metrics are from the proprietary Solsten deployment — the public repo is an earlier local prototype.
Memora
Encrypted payload storage, consensus-ordered event log, and challenge-response permissioned key release — a tamper-evident memory architecture for agents that need to prove what they remembered and when.
Retrieval Adaptation Pipeline
A 3,292-example procedural disruption benchmark from YouCook2 and WikiHow, and a config-driven evaluation pipeline covering retrieval augmentation, reranking, and VLM strategies — with persisted retrieval and generation traces for reproducible multi-method comparison.
TrustGraph
Four-predicate deterministic scanning for trust-boundary vulnerabilities — executable Foundry PoC exploit tests, Markdown/JSON reports, and VS Code diagnostics. The LLM enriches explanations; it never creates or suppresses a finding.
AgentOS
Isolated git worktrees, command allowlists, diff inspection, and a Rust-backed desktop runtime — bounded coding-agent execution with human review controls. A browser demo shows the UI and event flow; the desktop Tauri runtime handles real worktree operations.
Sageo
A verifiable identity and interaction layer for A2A-protocol agents — Coco smart contracts on MOI register agent identities and store hashed interaction proofs; a TypeScript SDK wraps A2A clients and handlers to inject trace metadata without storing raw payloads.
Clinical Speech ML Pipeline
End-to-end speech analysis pipeline: Expo mobile capture, FastAPI ingestion, FFmpeg normalisation, Whisper transcription, Librosa acoustic metrics, and Postgres persistence with an analytics endpoint. Prototype-stage — no clinical validation.
