From 763ccb1e4463c740f00293fe495b0b61af5def85 Mon Sep 17 00:00:00 2001 From: Derek Tu Date: Fri, 14 Aug 2026 13:00:01 -0700 Subject: [PATCH 1/5] feat(studio): bring Mecatl Studio in-repo as a Node module MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Studio is the local WEB client for the harness — chat with tool-call and approval cards, plus panels for the provider, MCP gateway, semantic model routing, skills, memory, and scheduled tasks. It lived in a private standalone repo, which cost it everything an in-repo client gets for free: no CI ran it, its test suite asserted invariants that had already gone stale against the code they described, it reached its harness through a hardcoded `../../mecatl`, and one developer-machine absolute path was compiled into the client bundle. It lands on the `website/` pattern: its own package.json + Taskfile under a `studio:` namespace, and a `studio` CI job running build + test + lint + typecheck. It is NOT a Go module — never in go.work, the layering DAG, the depguard allowlists, or the api-compat gate, and `task test` is unchanged. It is a CLIENT like mecatui: it consumes the public HTTP/SSE surface on loopback through a same-origin worker proxy and imports nothing from engine/ or internal/. Adapted in the move: - The workspace is RESOLVED, not hardcoded. The controller derives the repo root from its own location and reports it on /status; the client refuses to open a session until it knows one, rather than silently pointing mecated at the wrong tree. A clone anywhere now works unedited. - The starter-template residue the app was scaffolded from (D1/Drizzle wiring, the examples surface, the chatgpt-auth helper, the boilerplate README) is dropped rather than carried in. That also clears the two worker type errors it had been carrying, so typecheck is clean. - `task studio:dev` requires `bin/mecated`, and `task studio:stop` tears down the controller first so the supervisor stops the daemon it owns instead of orphaning it. ADR 0110 records the decision and its costs honestly — the repo now carries an npm tree and a Node install on every PR, and Studio's suite is a build-plus-source-invariant suite, not a browser test: it proves the app compiles, server-renders, and still holds its safety-critical shapes, NOT that a panel works against a live daemon.
