Latest change e7a1a89ddab5d1f27fad067498f11157de4d156c - feat(deploy): shared cross-environment health-sweep by Ólafur Búi Ólafsson

#!/usr/bin/env sh
# akurai-health-sweep — probe every AkurAI environment's public health endpoint.
#
# Canonical source: AkurAI-Build repo (scripts/health-sweep.sh). Installed to
# ~/.local/bin/akurai-health-sweep by scripts/install-host-tools.sh, so the CI
# worker (which bind-mounts ~/.local/bin) can run it as the final post-deploy
# step of any pipeline. Deploys therefore prove the health of the deployment
# AND every other environment: a regression elsewhere surfaces as a warning.
#
# Usage: akurai-health-sweep [--self NAME]
#   --self NAME  the environment just deployed. An unhealthy NAME fails the
#                sweep (exit 1); any OTHER unhealthy environment only warns
#                (exit 0). With no --self, any unhealthy environment warns and
#                the sweep still exits 0.
#
# Manifest: $AKURAI_ENV_MANIFEST or ~/.config/akurai-build/environments.tsv
#   Tab-separated lines: NAME<TAB>URL[<TAB>EXPECT]   (EXPECT default 200)
#   Blank lines and lines starting with '#' are ignored.
