name: Publish Desktop

# STAGE 3 of the decoupled release pipeline: PROMOTE a built + notarized version
# to "live". By this point:
#   - stage 1 (Release Desktop) built the installers, mirrored them to R2, and
#     registered them in D1 as unpublished (is_latest=0);
#   - stage 2 (local desktop/build/notarize-dmg.sh) notarized + stapled the mac
#     dmgs and re-uploaded the stapled bytes to R2.
#
# This workflow, triggered manually with the version to publish:
#   1. pulls every artifact for that version back from R2,
#   2. recomputes sha512 from the real (stapled) bytes and updates D1,
#   3. flips is_latest=1 for that version (clearing the previous latest per
#      platform) UNLESS it's a pre-release, which is recorded but never latest,
#   4. creates/updates the GitHub Release and attaches the installers.
#
# Run only after the mac dmgs for this version are notarized + re-uploaded.
