# CI-driven deploy for newsfeed (architecture deployment-gitea-actions.md).
#
# The workflow is the source of infra truth — hosts/ports/paths live here, not in a
# manifest. Build-and-rsync model: build the binaries + the SPA bundle, then rsync
# straight to the targets as the scoped `gitea_ci` user.
#
#   api + worker  -> slartibartfast.kosherinata.internal  (share one SQLite file)
#   web (SPA)     -> oolon.kosherinata.internal           (nginx serves + proxies /v1)
#
# Runners (see architecture gitea-runners.md): Rust build on `rust` (cargo toolchain);
# SPA build + deploy jobs on `fedora-43` (node + pnpm; ssh via git-core's openssh-clients
# dep; rsync + curl in the base). The whole fleet is Fedora, so binaries are built native —
# no glibc skew, no musl toolchain needed (deployment-gitea-actions.md §6: build on a
# runner no newer than the oldest target).
#
# One-time host prep (gitea_ci user, sudoers, service account, dirs, cert, vhost) is done
# by script/infra-setup.sh. Only secret required here: RSYNC_SSH_KEY (the runner's private
# key). newsfeed has no app secrets — SQLite has no password and tokens are hashed at rest.
