Root cause of PR checks stuck "Waiting to run": full-pytest on main ran ~12k tests including the slow registry on a 1.5-CPU / 1.2 GiB job cgroup for hours, monopolizing the only runner. Workflows: - full-pytest.yml: fast lane only (`not quarantine and not slow`) - nightly-full-pytest.yml: full suite including slow (schedule + manual) - lane-shas.yml: PR path filters so pin verification is skipped when the change cannot affect lane report bytes Docs: docs/ci-optimization.md + testing-lanes CI mapping. Infra (VM, same change window): job cgroup 2 CPU / 1800 MiB; hung full-pytest task stopped so the queue can drain PR smoke/lane-shas.

# Post-merge gate — runs the **fast** lane on every push to main.
|
||
#
|
||
# Why not full+slow here:
|
||
# Host is a 2‑vCPU / ~4 GiB VM shared with Forgejo + Postgres + Traefik.
|
||
# Job containers were capped at 1.5 CPU / 1.2 GiB. Running the entire
|
||
# ~12k-test suite including the slow registry (one 16 min fixture floor)
|
||
# monopolized the single Act runner for hours and starved PR smoke /
|
||
# lane-shas ("Waiting to run").
|
||
#
|
||
# Coverage contract:
|
||
# - This workflow: ``not quarantine and not slow`` (make test-fast).
|
||
# - Slow/soak/proof matrix: ``nightly-full-pytest.yml`` (schedule + manual).
|
||
# - PR gate remains smoke.yml (minutes) + path-filtered lane-shas.yml.
|
||
#
|
||
# See docs/testing-lanes.md and docs/ci-optimization.md.
