+# Builds and pushes pre-built Docker runner images to the Gitea registry.
+# These images eliminate the 40-120s setup tax on every CI job by baking
+# devx and all dependencies into the image.
+#
+# Triggers:
+# - On push to master (after post-merge release completes)
+# - Manually via workflow_dispatch
+#
+# The workflow builds 3 tier images in sequence:
+#   ci-base → ci-quality → ci-full
+#
+# Each tier builds FROM the previous one, so they must be built in order.
+# After pushing, a cleanup job removes old versions (keeps last 2 + latest).

+### LPT Test Distribution Algorithm
+
+`distribute_molecule` and `distribute_files` use **LPT (Longest Processing
+Time first)** scheduling instead of naive round-robin. This produces a more
+balanced distribution when test items have varying costs:
+
+1. **Weight estimation**: Each item is assigned a weight:
+   - Molecule scenarios: heuristic by name (`nextcloud`=10, `gitea`=8,
+     `binary`=2, default=3). See `_SCENARIO_WEIGHTS` in
+     `distribute_molecule.py`.
+   - Integration test files: weight by file size in bytes (as a proxy
+     for test runtime).
+2. **LPT assignment**: Items are sorted by weight (descending), then
+   each is assigned to the runner with the least total weight.
+
+This ensures heavy scenarios (e.g. `nextcloud`) are spread across
+different runners rather than clustered on one, reducing the
+longest-runner time from ~16 min to ~11 min with 6 runners.

 ## Config System
 
 devx uses environment variables with `.env` file fallback for configuration.
@@ -334,6 +367,133 @@ Projects using devx can override the default API URLs and language by setting
 `DEVX_*` environment variables or entries in their `.env` file. The config
 system loads `.env` automatically via `python-dotenv`.
 
+### pyproject.toml [tool.devx] Configuration
+
+In addition to `DEVX_` env vars, several devx tools read configuration from
+the `[tool.devx]` section in `pyproject.toml`. This allows per-project
+customization without environment variables.
+
+**Base config** (`[tool.devx]`):
+- `task_prefix` — Task ID prefix (e.g. `"DEVX"`, `"GRM"`, `"OBL-INFRA"`)
+- `vikunja_project_id` — Vikunja project ID
+- `repo_owner` / `repo_name` — Gitea repository coordinates
+- `gitea_api_url` / `vikunja_api_url` — API endpoints
+
+**Tool-specific config**:
+- `[tool.devx.check_mutable_globals]` — `scan_dirs`, `skip_dirs`, `known_safe`
+- `[tool.devx.check_test_coverage]` — `rules` (source_pattern → test_paths mapping), `skip_patterns`
+- `[tool.devx.check_agent_docs]` — `scan_dirs`, `deleted_files`, `deprecated_patterns`, `legitimate_indicators`
+
+## devx.mak — Shared Makefile Fragment
+
+`devx.mak` provides common Makefile targets that projects can include
+via `-include $(DEVX_MAK)`. This eliminates Makefile duplication across
+projects.
+
+**Available targets** (all prefixed with `devx-`):
+
+| Target | Purpose |
+|--------|---------|
+| `devx-create-task` | Create a Vikunja task |

+| `devx-checkmake` | Lint Makefiles with checkmake |
+| `devx-workflow-lint` | Static lint of Gitea Actions YAML (actionlint) |
+| `devx-workflow-dryrun` | Dry-run all workflows (act_runner) |
+| `devx-workflow-dryrun-safe` | Best-effort dry-run (skips if act_runner missing) |
+| `devx-workflow-check` | Static lint + dry-run |
+| `devx-notify-failure` | Create Gitea issue on CI failure |
+| `devx-lint-ruff` | Run ruff check |
+| `devx-lint-format` | Run ruff format --check |
+| `devx-typecheck` | Run pyright |
+| `devx-lint-bandit` | Run bandit security scan |
+| `devx-lint-deps` | Check dependencies for vulnerabilities (pip-audit) |
+| `devx-lint` | Run all lint targets |
+| `devx-test-unit` | Run unit tests without coverage |
+| `devx-pytest-cov` | Run pytest with coverage enforcement |
+| `devx-check-mutable-globals` | Scan for mutable path globals |
+| `devx-check-dep-docs` | Validate pyproject.toml deps are documented |
+| `devx-check-test-coverage` | Check changed files have corresponding tests |
+| `devx-check-docs` | Validate docs for stale references |
+| `devx-check-test-speed` | Verify test suite timing |
+| `devx-pre-push` | Run lint + tests before push |
+| `devx-clean` | Remove caches, build artifacts, coverage data |
+| `devx-setup-image` | Link /opt/venv + install project (for pre-built image CI jobs) |

+| `devx-build-images-dry-run` | Show what would be built/pushed |
+| `devx-clean-images` | Delete old image versions (keep last 2 + latest) |
+
+**Variables** (set BEFORE including devx.mak):
+- `DEVX_PYTHON` — Python executable (default: `python3`)
+- `DEVX_VENV` — venv directory (default: `.venv`)
+- `DEVX_BIN` — venv bin directory (default: `$(DEVX_VENV)/bin`)
+- `DEVX_LINT_PATHS` — paths for ruff/bandit (default: `src/ tests/`)
+- `DEVX_COV_PKG` — coverage package (default: `src/devx`)
+- `DEVX_TEST_PATHS` — pytest paths (default: `tests/`)
+- `DEVX_PR_BASE` — PR base branch (default: `master`)
+- `DEVX_GITEA_REGISTRY` — registry URL (default: `git.oblachno.oblachno.fyi`)
+- `DEVX_IMAGE_MANIFEST` — path to JSON manifest (default: `docker/images.json`)
+- `DEVX_IMAGE_OWNER` — package owner for cleanup (default: `oblachno-oss`)
+
+## Pre-built Docker Runner Images
+
+devx builds and publishes three tier images to the Gitea container registry
+to eliminate the 40-120s setup tax on every CI job:
+
+| Image | Contains | Used by jobs |
+|-------|----------|-------------|
+| `ci-base-latest` | Python 3.12 + devx[ci] + tea | detect-changes, detect-type, validate-commit-msg, pr-review, auto-merge, sync-wiki, vikunja, configure-repo |
+| `ci-quality-latest` | ci-base + devx[lint] + actionlint + checkmake | quality, badges |
+| `ci-full-latest` | ci-quality + devx[release,molecule,deploy] + git-cliff + OpenTofu | release, publish, release-dry-run, molecule-tests, deploy jobs |
+
+**Build process** (in `build-images.yml` workflow):
+1. `ci-base` builds FROM `gitea/runner-images:ubuntu-latest`
+2. `ci-quality` builds FROM `ci-base-latest`
+3. `ci-full` builds FROM `ci-quality-latest`
+
+Each image is tagged `latest` and pushed to
+`git.oblachno.oblachno.fyi/oblachno-oss/runner-images:<tier>-latest`.
+
+**Using images in workflows**:
+```yaml
+jobs:
+  quality:
+    runs-on: docker
+    container: git.oblachno.oblachno.fyi/oblachno-oss/runner-images:ci-quality-latest
+    steps:
+      - uses: actions/checkout@v4
+      - name: Set up environment
+        run: make setup-image  # links /opt/venv, installs project (no-deps)
+```
+
+**Image build/push tools** (tested Python modules):
+- `devx.tools.build_image` — Build and push Docker images from Dockerfile or manifest
+- `devx.tools.clean_images` — Delete old image versions via Gitea API (keep last N + latest)
+
+**Usage in project Makefile**:
+```makefile
+DEVX_PYTHON := $(BIN)/python
+DEVX_MAK := $(shell $(BIN)/python -c \
+    "from pathlib import Path; import devx; print(Path(devx.__file__).parent / 'make' / 'devx.mak')" \
+    2>/dev/null)
+-include $(DEVX_MAK)
+
+# Aliases for project-specific names
+lint-ruff: devx-lint-ruff
+workflow-lint: devx-workflow-lint
+create-task: devx-create-task
+```
+

+"""Pre-merge validation gate for auto-merge preconditions.
+
+Validates that a PR satisfies auto-merge requirements BEFORE expensive
+jobs (molecule tests, staging deploy) run.  This catches issues early:
+
+1. Branch name contains a task ID (e.g., ``DEVX-256-fix-foo``).
+2. PR title follows ``{PREFIX}-N: <title>`` format.
+3. PR title task ID matches the branch task ID.
+4. PR title matches the Vikunja task title (requires ``VIKUNJA_TOKEN``).
+5. Branch is not behind master (would trigger a rebase retry cycle).
+
+Exit code 0 = ready for auto-merge (preconditions satisfied).
+Exit code 1 = NOT ready — fix issues before pushing.
+
+Usage::
+
+  # CI (with VIKUNJA_TOKEN and REPO_TOKEN):
+  python3 -m devx.ci.check_auto_merge_ready \\
+      --branch "$HEAD_REF" \\
+      --pr-title "$PR_TITLE" \\
+      --repo "$REPOSITORY" \\

+
+  # Local (pre-push hook, no PR yet — validates branch + title format only):
+  python3 -m devx.ci.check_auto_merge_ready --branch "$(git rev-parse --abbrev-ref HEAD)"

+  python3 -m devx.ci.check_auto_merge_ready --branch "$(git rev-parse --abbrev-ref HEAD)" \\
+      --repo owner/repo --pr-number 123
+
+If ``VIKUNJA_TOKEN`` is not set, the Vikunja title match check is
+skipped (with a warning) — this allows local pre-push hooks to run
+without CI secrets.  In CI, the token is always set and the check is
+mandatory.

+"""Build and push Docker images to a Gitea container registry.
+
+Replaces raw ``docker build`` / ``docker push`` shell commands with a
+tested Python tool.  Supports:
+
+- Building from any Dockerfile with a configurable context directory
+- Tagging with multiple tags (e.g. ``latest`` + version)
+- Optional push to a Gitea registry (with login)
+- Dry-run mode (prints commands without executing)
+
+Usage::
+
+    # Build a single image

+        --dockerfile docker/ci-base/Dockerfile \\
+        --tag ci-base:latest \\

+        --push
+
+    # Build multiple images (from a manifest file)
+    python3 -m devx.tools.build_image --manifest docker/images.json --push
+
+The manifest file is a JSON list of dicts, each with:
+    - ``name``: image name (e.g. ``ci-base``)
+    - ``dockerfile``: path to Dockerfile (relative to repo root)
+    - ``context``: build context directory (optional, defaults to repo root)
+    - ``tags``: list of tags (optional, defaults to ``["latest"]``)
+
+Registry authentication uses ``REPO_TOKEN`` (or ``GITEA_REGISTRY_TOKEN``)
+and ``REGISTRY_USERNAME`` (or ``GITEA_REGISTRY_USERNAME``) environment
+variables, matching the existing CI workflow patterns.

+"""Create a pull request with the correct title from the Vikunja task.
+
+This tool is run **after** pushing a feature branch.  It:
+
+1. Extracts the task ID from the branch name (e.g. ``DEVX-31-fix-foo`` → ``DEVX-31``).
+2. Fetches the Vikunja task title for that task ID.
+3. Creates a PR with title ``{TASK_PREFIX}-N: <vikunja task title>``.
+
+This eliminates manual PR title entry and ensures the title always
+matches the Vikunja task — which is what the auto-merge workflow
+validates.
+
+If a PR already exists for the branch, the tool prints its URL and
+exits successfully (idempotent).

+Usage::
