shoney.arickathil b5d862dcc5 feat(framework): form-encoded body parsing — media_type + form_values
- media_type(req): content-type lowercased, "; charset=..." stripped,
  "" when absent — the content-negotiation hook
- form_values(req): application/x-www-form-urlencoded body -> decoded
  pairs through the existing query decoder ('+' as space, %XX); nil on
  any other content-type so a JSON body is never misread as a form key
- web-app CreateProduct accepts form OR JSON; shared create_product
  insert path; field/number validation answers 400
- probe 7/7 (plus/pct decode, empty value, case + charset param, json
  and missing content-type nil, empty body, media_type strip) + ASan
- gate grows 17 -> 19: form create 201 with decoded name, non-numeric
  price 400; hit() gains a content-type argument
- README: checklist row form ✅ (multipart stays candidate), limits
  paragraph updated; story 16 + board record the landing
- gates: web-app 19/0, oop-e2e 89/0, deps-accept 8/0, log-watcher 7/0,
  employee 8/0, woc-test green

web-app — the storefront sample

A small store: Product/Order as @table classes, JSON routes, one auth middleware — built on writeonce-framework, 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 "";
  }
}
