# Nightlies are datestamped prerelease tags (vX.Y.Z.devYYYYMMDD) cut from
# the newest green commit on main by .github/workflows/nightly-release.yml
# (about 04:30 UTC). This script resolves the newest nightly tag and
# installs it with uv, which pins the whole install (omnigent,
# omnigent-client, omnigent-ui-sdk) to that one tagged commit.
#
# Requirements: git, uv, and Node.js 22+ with pnpm (the wheel build
# compiles the web UI and fails with an actionable message if they are
# missing).
#
# Idempotent: exits fast when the newest nightly is already installed,
# so it is safe to run from cron, e.g. daily at 9am:
#   0 9 * * * bash /path/to/update_nightly.sh >> "$HOME/.omnigent-nightly.log" 2>&1
