A 4Runner generation change moves the part-number series, the slide length, and the turnbuckle. That mapping lived in one senior builder's head and on hand-maintained paper checklists. It now lives in a versioned catalog that can be diffed, linted, and reviewed.

• Adding a kit means adding a file. Every vehicle-specific fact — parts, rules, sheet layout, provenance — lives in a versioned YAML catalog. Nine catalogs ship today and none of them needed code.
• It says when it doesn't know. An order it can't fully resolve produces a gap report naming exactly what it couldn't work out. Two lint gates check every catalog before it ships, and the sheet renderer is pinned to golden files so printed output can't quietly drift.
• Theirs to run. Intake reads order PDFs and screenshots through one deterministic parser (pdfplumber plus platform OCR), with optional Shopify pull by order number. Handed off as source they host on their own hardware — no vendor account, no dependency on me.

An assistant that can only write code into a file is guessing about the result. Arenula lets it change the scene, compile, and read back what actually happened. Read the docs →

• Every write proves itself. Mutations return a verified read-back of engine state, so the caller can tell a real change from a silent no-op. Anything that doesn't resolve to a real engine resource errors with a usable suggestion.

The wire protocol isn't published and the official app mirrors everything through the vendor's cloud. This repository is that protocol, written down with the provenance of each finding, plus a tested implementation of it. Read the source →

• It documents the trap. Controller settings only apply as one bundled write — a lone single-field write sends zero bytes and reports no error. That is the class of bug a unit test against your own encoder can never catch, because your encoder is correct and the device simply ignores it.

Claude Code gives a plugin no way to know which model it runs against, so instructions written for older models quietly degrade newer ones: mandatory verification steps, standing review gates, delegate-by-default. This layer measures that drift and corrects it from the one layer that outranks every plugin. Read the source →

• Classes, not plugin names. Six superseded instruction classes, each traceable to a specific line of Anthropic guidance. The scanner matches on what an instruction does rather than who ships it, so a plugin installed tomorrow is already covered.
