# Render the Scoop manifest for rdbms-playground to stdout.
#
# Pure function of its inputs — NO network, NO jq/ruby — so it runs unchanged in
# the CI job container (node:22-bookworm-slim: bash + coreutils only). Given a
# version and the two Windows asset SHA-256 hashes it prints a complete,
# schema-valid Scoop manifest. The publish.yaml `scoop-bucket` job fetches the
# hashes from the release's .sha256 sidecars and commits the result into the
# lazyeval/scoop-bucket repository as rdbms-playground.json.
#
# Manifest updates are CI-driven (this script, per release), so the manifest
# carries `checkver` (so `scoop status` / the community excavator can see when
# the bucket lags upstream) but deliberately NO `autoupdate` — our pipeline is
# the updater, not Scoop's maintainer tooling.
#
# Usage: render-scoop-manifest.sh <version> <hash-x64> <hash-arm64>
#   <version>     version, with or without a leading 'v' (e.g. 0.2.0 or v0.2.0)
#   <hash-x64>    sha256 of the x86_64-pc-windows-gnu.exe asset
#   <hash-arm64>  sha256 of the aarch64-pc-windows-gnullvm.exe asset
