name: CI
# Three levels of testing:
#   - every PR: lint, unit tests (16 property walks), integration tests, and
#     the smoke end-to-end tests (`smoke` marker);
#   - a PR labelled e2e:full, a push to main and a manual run: all 48 walks
#     and the whole end-to-end suite;
#   - a published release: the full set again before its image (release.yml).
on:
  # Only main on push. A PR branch is already covered by the pull_request
  # event, and running both fired two identical suites concurrently — which
  # doubled the LLM tokens the live tests spend and tripped the proxy's
  # per-minute limit.
  push:
    branches: [main]
  pull_request:
    # labeled: adding e2e:full runs the full set; any other label, nothing.
    types: [opened, synchronize, reopened, labeled]
  # Manual re-run, e.g. after rotating a credential or raising a budget cap.
  workflow_dispatch:

# A newer run for the same PR or branch cancels the one it supersedes: there
# is one runner, so a stale run would hold it (and the GPU) to the end. Adding
# a label other than e2e:full starts a run whose jobs all skip; it gets a
# group of its own, so it can't cancel the real one.
#
# Gitea triggers on `labeled` but hands the workflow its own name for the
# action, `label_updated` (and `synchronized` for a push), so each check
# below accepts both. Nor does it say which label was added
# (`github.event.label` is empty), so a label event counts when the PR now
# has e2e:full; adding another label to an e2e:full PR restarts its run.
