# PPE E2E content seed (§9 deployed-environment harness).
#
# The Tier-1 docker seed (seed-gitea.sh) stands up a throwaway Gitea. PPE
# instead runs against the REAL Gitea (git.wiggleverse.org) — which it
# shares with prod. To exercise the §22.4a metadata UI (faceted filter
# SLICE-3, edit panel SLICE-4, bulk bar SLICE-5) on PPE WITHOUT touching
# real OHM content, this script seeds a DEDICATED, PPE-only registry +
# content repo:
#
#   wiggleverse/rfc-registry-ppe   — PPE's own project registry (prod
#                                    keeps using wiggleverse/rfc-registry,
#                                    so prod is never affected).
#   wiggleverse/rfc-app-ppe-content — content for the one project the PPE
#                                    registry describes: a default
#                                    (document) collection + a faceted
#                                    `bdd` named collection with a
#                                    fields: schema + three entries.
#
# Point PPE at the PPE registry with:
#     flotilla-core overlay set rfc-app-ppe REGISTRY_REPO=rfc-registry-ppe
# The app's startup reconciler sweep loads this content into cached_rfcs
# on the next deploy/restart (no webhook needed for the initial load).
#
# Auth: pass a Gitea token with org repo-create + content-write scope via
# GITEA_TOKEN (the wiggleverse admin token — see the wgl-gitea-admin
# skill; never echo it). The collection path the E2E suite hits is
# /p/ohm/c/bdd, so the seeded project id is `ohm` (matching the Tier-1
# seed and DEFAULT_PROJECT_ID=ohm) and the collection is `bdd`.
#
# Idempotent: repos/files that already exist are left as-is. Pass
# RESEED=1 to force-overwrite the three entry files back to their seed
# values (so a re-run restores SLICE-4/5's expected preconditions).
