The pulse — GitHub contribution activity

Annual contributions from 2020 to present, with a running cumulative total; the peak year glows.

Weekday contribution share: a donut of each weekday's percentage of the last ~16 months (500 days) of contributions; the glowing slice marks the peak day.

Selected work — computational neuroscience, robotics, 3D and scientific software projects

engram: Engram Neural Modeling Labs is a public placeholder for computational-neuroscience, spiking-network and neural-modeling experiments; its repository says the code will be open-sourced after publication. NCP: NCP is a versioned, project-agnostic canonical-JSON contract connecting neural simulators or neuromorphic controllers to robots, UAVs, simulators and read-only analysis clients. It has a Rust reference, an independent TypeScript validator/client and Python/C/C++ bindings; HEAD is an unreleased, release-blocked 1.0 candidate, while v0.8.0 remains the latest immutable release. Languages: Rust, TypeScript, Python, C, C++.
prisoma: Prisoma is a public Rust/Python research toolkit for auditable experiment semantics and intervention-grounded diagnosis of Vision-Language-Action policies, building provenance-complete capture-intervention-replay infrastructure. PID is a conditional diagnostic behind explicit gates; the 0.9.0 release candidate is a source/research preview, not a scientific-results or production release. Languages: Rust, Python. crebain: CREBAIN (Adaptive Response & Awareness System) is a research-only Tauri prototype for Gaussian-splat scene visualization, simulated cameras, ML object detection, multimodal 3D tracking and ROS/Gazebo drone simulation, built with Tauri 2, React 19 and Rust. The 120 Hz physics and ROS capabilities remain in progress. Languages: Rust, TypeScript.
melkor: Melkor is a C++17 3D Gaussian-splat toolkit for deterministic conversion, inspection, geometry-based scene completion, viewing and explicit external reconstruction pipelines, with CPU/Metal and optional CUDA backends. v2 hardening is in progress; no supported production binary release is available. Languages: C++, Python, JavaScript. galadriel: Galadriel is an experimental safe-Rust cross-sensor consistency monitor for multi-sensor fusion, combining NIS/CUSUM, sign-preserving correlation over producer-attested projections and optional PID diagnostics. v0.9.0 is a pre-1.0 supervisor-review source release; evidence is synthetic/component-level, not field validation. Languages: Rust.
pid-rs: pid-rs is a safe-Rust library for shared-exclusions Partial Information Decomposition and mutual-information estimation: categorical SxPID, KSG MI and default-off experimental continuous shared-exclusions/PID surfaces. v0.9.0 is a GitHub-only source-review prerelease. Languages: Rust, Python. haldir: Haldir Gate is an experimental Rust mission-authorization reference monitor for NCP: it validates signed controller intents, deployment and mission admission, and deterministic policy, then prepares Gate-owned plant commands and signed decision receipts. Its 0.9 review remains NO_GO; it is not production-ready or airworthy. Languages: Rust.
manwe: Manwe is an alpha airspace-perception research and validation workbench spanning vision, audio, multi-camera geometry and multi-target tracking, with a Python numerical/training package and Rust/Candle inference benchmarks. It targets candidate outputs for systems such as Crebain but currently ships no drop-in Crebain adapter. Languages: Python, Rust. cortexel: Cortexel is a pre-1.0 TypeScript library and CLI that validates strict declarative JSON requests for neural-simulation figures and renders deterministic, accessible SVG artifacts plus exact-value tables, with fail-closed provenance. v0.9.0 has no stable published package or DOI. Languages: TypeScript.
relief-atlas: relief-atlas is a Python generation pipeline and 10,079-item corpus of AI-generated GLB meshes for disaster relief, humanitarian aid and civil protection; licensing is recorded per asset. Languages: Python. cobot-atlas: cobot-atlas is a Python generation pipeline for a public MIT dataset of 2,023 unique glTF 2.0 Binary meshes (2,024 GLB files, 33.5 GB) for robot/cobot simulation, manipulation research, VLA training and benchmarking. Languages: Python.

Conceptual standalone-first ecosystem map. Optional NCP role paths connect Engram as a simulation responder or direct command proposer, CREBAIN as sole body and final software actuator admission authority, Haldir as a gated command proposer, and Galadriel and Prisoma as read-only observers. Every command remains a proposal until CREBAIN independently admits it under current session and body-lease authority. In gated mode Engram sends Haldir-local signed intent carrying no NCP authority; Haldir independently creates and authorizes a new NCP command. A separate default-off Galadriel-Haldir seam carries deny-only assessment and authenticated disposition; absence never grants authority. Separately declared out-of-band CREBAIN telemetry may feed Galadriel. pid-rs is an in-process protocol-neutral library with no wire role; Cortexel is a one-way labelled Engram export sink with no control path. Other lines are research, tooling or data inputs, not control paths. NCP 1.0 remains an unreleased, release-blocked candidate; no line claims deployment or qualification.

Authority & dependency: every core runs standalone. NCP is an optional neutral contract: Engram has separate simulation/direct-proposal roles; Haldir is a gated command proposer; Galadriel and Prisoma only observe. Every command remains a proposal until CREBAIN independently admits it under its current session and bounded body-authority lease; CREBAIN alone owns body state and final software actuator admission. In gated mode Engram → Haldir carries local signed intent, not NCP authority; Haldir independently authorizes a new NCP command. Galadriel ↔ Haldir is a separate default-off deny-only assessment/authenticated-disposition seam whose absence never grants authority. CREBAIN → Galadriel telemetry is separately declared and outside NCP. pid-rs is an in-process library only, with no wire role; Cortexel is a one-way labelled-export sink with no control path. These are intended, historical, research or data relationships. NCP 1.0 remains an unreleased, release-blocked candidate—not a deployed or qualified integration.
