shoney.arickathil 47a920f19a feat(serve+view): file serving, downloads, supported systems; rename
- rename the two libraries: writeonce-framework -> writeonce-serve
  (`use serve`), wo-html -> writeonce-view (`use view`). Names say the
  ROLE now; every sample, script, gate and live doc follows
- stories/specs/plans keep the old names: they are dated records, and
  both library READMEs carry a "renamed 2026-08-25" note
- serve/http/files.wo: StaticFiles { dir, max_bytes } — traversal
  refused not normalised, extension content types, attachment
  disposition for archives. Lifted out of the shop, which had said in
  a comment that it belonged in the framework
- shop drops its private copy and mounts the framework's
- site: /dl/*path over $WO_DIST (default ./dist), 16 MiB ceiling
- /install gains supported systems — Linux x86-64, glibc >= 2.38,
  not musl — read off `file` and the binaries' GLIBC_ symbol
  versions, not off a wish list; plus GitHub release as primary,
  /dl as mirror, and the sha256 verify step
- site-accept: 17 -> 21 checks (supported systems, gzip download with
  a binary-safe probe, checksum, /dl traversal 404)

Verified on 192.168.0.165: the real 960,820-byte tarball downloads
as application/gzip and its sha256 matches the published digest.

Gates: oop-accept MET, site 21/0, web-app 46/0, fibers 10/0,
db-actor 8/0; shop rebuilt and its /assets served by the framework.

# web-app — the storefront sample
A small store: `Product`/`Order` as `@table` classes, JSON routes, one auth
middleware — built on [`writeonce-serve`](../writeonce-serve/), which
it imports **through `[deps]`** (iteration 15). This app is iteration 16's
acceptance workload: `just web-app` runs the whole chain — fetch → lock →
build → serve → curl matrix → restart persistence → SIGTERM.
## Routes
| Route | What |
| --- | --- |
| `GET /products` | list (JSON array) |
| `GET /products/:id` | one product or 404 |
| `POST /products` | create from a JSON body (`name`, `price`, `stock`); 400 on malformed JSON; 409 on a duplicate name (`@unique`) |
| `POST /orders` | create (`product`, `qty`); FK checked |
| `DELETE /products/:id` | 409 while orders reference it (FK restrict), 200 after |
Every request needs `authorization: Bearer <token>` (the auth middleware);
the token comes from the `WA_TOKEN` env var.
## Run
woc . # fetches deps, builds target/web-app
WA_TOKEN=secret WO_DATA=./data ./target/web-app 8080
## TLS / HTTP2
None here, deliberately: deploy behind nginx/caddy — the proxy terminates
TLS+ALPN and speaks h2 to browsers while this backend serves HTTP/1.1
keep-alive. Sketch:
server {
listen 443 ssl;
http2 on;
location / {
proxy_pass http://127.0.0.1:8080;
proxy_http_version 1.1;
proxy_set_header Connection "";
}
}
