-##### Goal
+> Merged `feat/flutter-cicd` → `main` (2026-05-22).
-
+> Added Forgejo Actions workflows: `flutter-analyze.yml` (runs `dart analyze --fatal-infos` on all 8 packages/apps) and `flutter-test.yml` (runs `flutter test` per package with per-package pass/fail count and aggregate summary table). Workflows trigger on PRs to main and all non-main branch pushes using `ghcr.io/cirruslabs/flutter:stable` container. Populated `tools/` directory with `run_all_tests.sh` (local test runner with optional `--analyze` flag) and `README.md` documenting scripts and CI workflow inventory. All existing tests passing (20 core, 41 design_system, 294 feature_wordpress, 24 kell_web — 379 total). Analyze clean.

-##### Requirements
-
-- add Forgejo Actions workflow for `dart analyze` on PRs
-- add Forgejo Actions workflow for `flutter test` execution on PRs (per package)
-- add basic test result reporting (pass/fail count per package)
-- ensure workflows work for both web and Android targets
-- populate `tools/` directory with any CI helper scripts if needed
-
-##### Definition of done
-
-- PRs trigger automated analyze and test runs
-- test counts are reported in workflow output
-- workflow files committed under `.forgejo/workflows/`
-- `tools/` directory populated or removed if not needed
