name: CI

# Signage is a standalone repository: every job installs it with --frozen-lockfile from its own
# pnpm-lock.yaml and takes Ekklesia's module-development packages (@ekklesia/*) from Ekklesia's
# public package registry (.npmrc; platform ADRs 0053 and 0054). Only the integration job fetches
# Core source: one immutable commit through the pinned Gitea pull ref in ci/platform.env, used as the
# generic deployment harness and image source, never as a workspace dependency.
#
# The same trust rules as the platform's own CI (docs/development/security.md there):
#   * every action is pinned by a full commit SHA;
#   * every checkout sets `persist-credentials: false`, and nothing in this workflow pushes;
#   * no repository, organization, or instance secret is referenced;
#   * there is no `pull_request_target`;
#   * the self-hosted runner executes trusted, reviewed code only.
#
# The server is Gitea 1.27, which honours `concurrency` cancellation; `permissions` and
# `timeout-minutes` are declared so the workflow is correct wherever they are enforced.
