# Administrators and Roles screens in cabana with their privilege rules, the
# cross-controller record action seam (D-14) and the SPA's field triggers and
# per-record permission locks (D-21).
#
# Stages:
#   go         go vet ./..., go test -short ./..., go -C examples/hello test
#              ./..., then the Docker-free screen, seam, ceiling, trigger and
#              record-lock tests by required name (-short).
#   docker     Docker host only: every Postgres test of plans 01 and 03 by
#              required name (without -short), the SC-1 regression tests of
#              the admin commands, auth, account and OpenAPI conformance, and
#              go test ./modules/surf.
#   admin      npm --prefix admin run typecheck, the vitest run (the trigger,
#              permission editor, form state, form view and preview view test
#              files must pass), the browser run (record-actions-wrap must
#              pass), scripts/check-admin-openapi.sh --check and
#              scripts/check-admin-dist.sh.
#   docs       TestDocsTree, summer docs:build --check, and no framework
#              source, README or docs page under modules/ or docs/, and no
#              test file of this phase, names a consuming application.
#   sc1        SC-1: no commit in PHASE1961_BASE..HEAD that touches a phase
#              file also touches modules/cabana/commands.go,
#              token_commands.go or account.go (the admin commands and My
#              account stay as they were).
#
# A Go stage exits non-zero on a failing command, or on a go test -json run
# that fails, skips a test (a subtest included), matches zero tests, prints
# "no tests to run" or misses a required name. The vitest detector refuses a
# run whose summary is not all-passing, that reports a failed, skipped or
# todo test, or that has no passing line for a required file. --self-test
# proves the detectors on planted output and the docker NOT RUN rule with a
# docker that does not answer.
#
# --all runs self-test, go, admin, docs and sc1, then docker when a Docker
# daemon answers (NOT RUN docker otherwise, a failure with
# PHASE1961_REQUIRE_DOCKER=1).
#
# Environment overrides: PHASE1961_ROOT (this repository), PHASE1961_BASE
# (the commit before the phase; default the parent of the first commit that
