# CI gate for GoblinPay. Mirror of .gitea/workflows/ci.yml, plus the workspace
# trim below (this hosted runner can't reach the private siblings; a deploy-host
# runner with the siblings present does not need it).
#
# What runs where:
#   - fmt + the gp-core clippy/test gate run on ANY runner — BUT every cargo
#     command runs `cargo metadata` over the whole workspace first, and
#     gp-nostr/gp-server/gp-goblin-sender have path deps into out-of-repo
#     siblings (nip44/ and the private goblin/ tree) that a hosted runner
#     can't check out. `-p` scoping does NOT skip that resolution, so the trim
#     step drops those members before any cargo command. What's left (gp-core,
#     gp-wallet) is self-contained and holds the domain logic (config, invoices,
#     matching, webhooks, rates, the connector seam).
#   - The FULL gate (gp-nostr + gp-server + the gp-goblin-sender round-trip, via
#     ./ci.sh) needs the sibling checkouts next to the repo: nip44/ (the Nostr
#     path) and goblin/ (the round-trip gate). It runs where the workspace is
#     laid out like the deploy host; otherwise it is skipped below.
