Root `make check` only ever ran the frontend, so the "main is always
green" policy was satisfied vacuously: the Go backend could be entirely
broken and the root gate stayed green.
- The backend moves onto scripts-to-rule-them-all. Its test, lint, fmt,
fmt-check, build, run and clean implementations now live in
`backend/script/`, and `backend/Makefile` is thin shims. The backend
is its own project (own module, README, LICENSE, linter config,
Dockerfile stage), and `Dockerfile.backend` only copies `backend/`
into its builder, so its scripts have to live under `backend/`.
- The root `script/test`, `script/lint`, `script/fmt` and
`script/fmt-check` now run the frontend step and then the matching
`backend/script/*` step, so `script/check` — and therefore the
pre-commit hook — gates both halves. The frontend-only steps moved
into `script/frontend-*` so nothing is duplicated.
- `script/bootstrap` now provisions the backend's toolchain as well,
because widening the gate without widening bootstrap left the
documented fresh-clone path (`make setup`) installing a pre-commit
hook that rejected every commit with `golangci-lint: not found`. Go
is reused when the installed version is new enough, otherwise it is
installed from the official `go1.25.7` release archive; golangci-lint
is installed at exactly `2.7.2`, the version `Dockerfile.backend`
pins, so local findings match CI. Both come from a specific release
archive whose sha256 is hardcoded here and verified before anything
is unpacked — never an install script piped to a shell — and both are
symlinked onto `PATH`, since nvm-style activation does not reach
`make` or the git hook.
- `script/frontend-check` is the frontend half of the gate, exposed as
the `frontend-check` target, for the frontend Dockerfile: its build
stage is a node image with no Go toolchain. The backend half is gated
by `Dockerfile.backend`, and `script/cibuild` builds both images, so
the two Dockerfiles together still gate the whole repo. The
`backend-check` target is the mirror of it. Both targets are named
after the script they shim, like every other target.
- `script/cibuild` builds both images through one `build_image` helper,
and the Gitea workflow's only build step is `script/cibuild`; the raw
`docker build -f Dockerfile.backend .` is gone from the workflow.
`script/docker` likewise builds and tags both images.
- `backend/Makefile`'s `hooks` target is removed. It wrote the same
`.git/hooks/pre-commit` as `script/install-precommit`, so the two
clobbered each other and the developer silently ended up gating on
only one half of the repo. `script/install-precommit` is now the only
installer, and the hook it writes runs the repo-wide `script/check`.
- `backend/Makefile`'s `docker` target is removed too: the backend image
builds from the repo root with a root-level Dockerfile, so it belongs
to the root `script/docker` and `script/cibuild` rather than to a
backend script that would have to reach outside `backend/`.
- `backend/script/lint` verifies that `.golangci.yml` still matches its
pinned sha256 before running the linter. Offline hash comparison, no
network. The pin is marked provisional in the file: it is the config
currently on `main`, and the comment names PR #31 and the canonical
hash that must replace it when #31 lands.
- Every script locates the repo root with the mandated
`$(cd "$(dirname "$0")/.." && pwd -P)` idiom, `cd`s there, and calls
siblings as `"$ROOT/script/<name>"`; the `SCRIPT_DIR` variant is gone.
READMEs at the root and in `backend/` document every script, the
backend's Getting Started separates commands run from `backend/` from
those run at the repo root, and `TODO.md` records the change.
Local CPE (192.168.100.1) is always monitored. On startup, probe
192.168.1.1, 192.168.0.1, 192.168.8.1, and 10.0.0.1 in parallel
and add whichever responds first as "Local Gateway".
