From 8592bba9e3fa350bd26597e86e5a6b557c066735 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bot=20of=20Thomas=20G=C3=BCttler?= Date: Mon, 8 Jun 2026 16:11:17 +0200 Subject: [PATCH] chore(dagger): align Dagger versions to v0.21.4 and add lint (#544) ## Summary Closes #542. - Bumped `ci/dagger.json` `engineVersion`, the Forgejo runner Dockerfile (`.forgejo/Dockerfile`), and the example `dagger-engine.service` unit in `DAGGER.md` from `0.20.8` -> `0.21.4` so they match the running engine and the CLI already pinned by `flake.nix`. - Added `scripts/check_dagger_versions.sh` which parses the four pinned references and fails if any drift apart. - Wired the lint into `Taskfile.yml` (`task check-dagger-versions`) and `.pre-commit-config.yaml` (triggered when any of the four pinned files change). ## Verification - `./scripts/check_dagger_versions.sh` -> passes, all four references at `v0.21.4`. - Temporarily edited `ci/dagger.json` to `v0.21.3` and re-ran the script: exits non-zero with a clear "out of sync" error. Generated with Claude Code.
