public engineering index
Arca publishes tools, operational research, and upstream fixes. This is the index: what we maintain, where we contribute, and what actually landed.
Public repository ≠ open source. We list a project as OSS only when it carries an explicit license.
01 / MOVEMENT
Merged, closed, open, review, and authorship credit stay distinct here. Every row links its canonical public evidence.
Newest 8 of 82 public events. The machine-readable feed at /activity.json carries the full record.
Back to top ↑02 / MAINTAINED
Licensed projects we maintain, steward, or publish, with the source and our responsibility made clear.
Deterministic OpenClaw diagnostics and guarded repairs, with optional AI explanation that never becomes executable shell.
The CLI, installer, tests, security model, capability contract, and releases are public.Independent diagnostics, safe repair, and sanitized support tooling for Hypersnap and Snapchain node operators.
The operator CLI, installer, safety model, and local test suite are public.A TypeScript SDK joining agent identity, payments, data, and MCP tooling without pretending those layers already fit together.
Source, examples, package manifests, and license live in the repository.A source-labelled knowledge agent and bundle for Hypersnap, Snapchain, and Farcaster-fork operators.
The prototype, source corpus, roadmap, and unfinished bot-hardening boundaries are public.A machine-readable, evidence-backed record of upstream issues, technical comments, proofs, and pull requests.
Every record requires a public URL. Open, closed, and merged work stay distinct.A root-cause write-up and runnable local patch for the OpenClaw TUI stuck-spinner delivery failure.
The symptom, exact version boundary, upstream trackers, patch, and reproduction are public.A desktop pixel-art tool for rebuilding voxel models from orthographic views and exporting directional sprite sheets.
The original implementation, Electron app, Playwright verification, and license are public.A CLI harness for comparing whether language models refuse, evade, deny, or substantively answer a documented historical question.
The test suites, provider adapters, scoring boundaries, npm package, and license are public.The source, machine-readable records, claim checks, and refresh jobs behind this public index.
The site source, activity feed, claims validator, CI, and license are public.03 / SUPPORTED

Back to top ↑05 / METHOD
Source, runtime, issue history, and current ownership before proposed code.
Reproduction first. Exact-head tests and production-path evidence where the change warrants it.
Open is not merged. Public is not automatically OSS. Support is not affiliation.
Repository, PR, commit, issue, transcript, or a clear statement that evidence does not exist yet.
