- router/router.wo: Handler (handle(req) -> Resp) and Middleware
(before(req) -> ?Resp; nil = continue) structural interfaces; Route/Mw
record classes built as ctor literals at the registration site — the
ownership shape the corpus pins (run/container-owned-move);
route_match with :param captures over '/'-split segments (empties
dropped, first mismatch wins).
- app.wo: App holds the middleware chain + route table (take-push),
satisfies http's Dispatcher, dispatches middleware-then-first-match,
fills the captures onto the borrowed request in place (Dispatcher takes
`mut req` — the borrow checker rightly refused rebuilding a Req from
borrowed maps; captures collect locally so a failed match never touches
the request), 404 fallback, serve(host, port) delegation.
Verified against a throwaway app (not committed): middleware 401
short-circuit without the token; /things/:id captures 42 into the body;
unknown path 404; a DIV0 handler answers 500 and the next request is
served; SIGTERM clean. Framework image emits at 12161 bytes.
