From d2feca7375ba3ca8bdc2720d771c12ef7cd6974a Mon Sep 17 00:00:00 2001 From: Marcel Wege Date: Thu, 20 Aug 2026 18:33:15 +0200 Subject: [PATCH 1/3] feat(sidecars): move the runner sidecars, shim and transcript CLI out of core MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Epic byte5ai/omadia#470 P4. The dev-platform half of core's `middleware/sidecars/` (dev-runner, dev-runner-daemon, dev-dind), the runner shim, the compose overlay and the operator transcript CLI now live beside the plugin they serve. The other four sidecars in core (pii-detector, privacy-detector-presidio, skillspector, updater) are core's and stay there. What moved: sidecars/dev-runner/ 2 files (image that runs exactly one job) sidecars/dev-runner-daemon/ 30 files (control plane + egress proxy) sidecars/dev-dind/ 2 files (the one privileged service) packages/runner-shim/ 21 files (was middleware/packages/dev-runner-shim) docker-compose.dev-platform.yaml packages/plugin/scripts/dev-transcript.ts Paths rewritten for the new root: the dev-runner Dockerfile builds the shim from `packages/runner-shim/`, and the compose overlay's build contexts point at `sidecars/`. Compose resolves `build.context` relative to the file that declares it, so the overlay still composes against a core `docker-compose.yaml` living anywhere else. The daemon becomes a workspace member so the repo has ONE typescript, ONE @types/node and one lockfile. Its own `typecheck` script had never been wired into any CI, and turning it on found 38 errors — all pre-existing on core's pinned TypeScript 5.9, so none of them are the port's doing. Two are real defects rather than annotations: - `proxyClient.mjs` passed its abort callback as `withDeadline`'s THIRD argument, which is `label`. The timeout message read `() => controller.abort() exceeded 5000ms` and the abort never fired, so a hung egress proxy leaked its fetch until the process exited. - `buildEgressProxyClient` passed `tokens[0]` through unchecked. On an empty DEV_RUNNER_DAEMON_TOKEN the daemon would have authenticated to its own proxy as `Bearer undefined`; every job then sees 407 on every request, which inside a runner presents as a total network outage. Now a boot refusal. `PolicyClient.fetchJobPolicy`'s typedef had also drifted a whole parameter behind its implementation. The shim's suite is compiled and run as real files rather than bundled: `src/index.ts` self-invokes behind an `import.meta.url` main guard that a bundler silently defeats. 450/450 daemon tests and 76/76 shim tests green; both packages typecheck clean. --- docker-compose.dev-platform.yaml | 330 +++++ package-lock.json | 743 +++++++++- package.json | 8 +- packages/plugin/scripts/dev-transcript.ts
