# CI lanes per FabledRulebook forgejo.md "CI philosophy":
#   - lint:        ruff only, no dep install — fast-fail for the common lint bounce.
#   - unit:        pytest -m "not integration"; no service containers, no DB.
#   - integration: postgres service container; boots the real app + runs all
#                  (core + bundled-plugin) migrations.
# Single repo: first-party plugins are bundled in-tree under plugins/, so the
# unit lane imports them directly — no cross-repo checkout.

on:
  push:
    branches: [dev, main]
  # pull_request intentionally absent — push on [dev, main] already fires CI for
  # every dev commit and dev→main PRs. Single-operator repo, no fork PRs.

jobs:
  # Fast-fail lint lane. ruff is pre-installed in the ci-python image, so this
  # runs with NO dependency install and surfaces lint bounces in seconds.
