+# CI/CD — ERP Core. One workflow for pull-request checks and the production deploy
+# (https://erp.hexdive.com). Runbook: docs/40-DEPLOYMENT.md, "Active".
+#
+# Which jobs run for which event:
+#   PR opened / updated into Dev or production → checks: detect → backend / frontend / e2e-typecheck /
+#                                                scripts (only the sides the PR touches) → ci-ok
+#   PR merged into production                  → build-and-deploy (checks are skipped)
+#   PR merged into Dev, or closed unmerged     → nothing (every job skipped)
+#   Run workflow (manual)                      → build-and-deploy with the deploy_backend / deploy_frontend boxes
+#
+# Checks: `ci-ok` is the single required status check for branch protection. It passes when every
+# check passed or was skipped, and rejects PRs into production that don't come from Dev or hotfix/*.
+#
+# Deploy: same shape as the Fitness workflows (publish on the host → stop → copy → fix permissions →
+# start → verify), plus: only the side whose folder changed in the PR is deployed, the database is
+# backed up when the PR changes migrations, and the verify steps FAIL the job (no automatic rollback).
+# Detection only sees the PR being merged: after a failed deploy, fix it and use "Run workflow".
+# The test environment is on hold (deploy/on-hold/).
+#
+# Security model: the dotnet/npm/tsc/eslint check work runs in capped containers without secrets, but
+# the deploy/scripts/*.sh steps come from the PR checkout and run on the host runner as root, some with
+# ERPSECRET in their environment. Acceptable only while the repo is private and every PR author is a
+# trusted team member.
