- five forks locked: cookies: multi SetCookie beside unchanged headers
map; bare-name random_bytes(n)->Bytes; structural-400 in parse_request
+ on-demand cookie() helper; base64(value).base64(mac) signing;
app-supplied key, no middleware (that is iteration 3)
- validated against .dev/reference/fiber (v3, 3ca9a9d): exactly ONE
language enhancement needed (the CSPRNG); repeated Set-Cookie, cookie
attributes, parsing and signing all map to existing primitives
- corrects phase A registry: random_bytes joins the crypto-family
bare-name table (emit.ml b_* + types.ml), NOT wob.h's module enum;
next free id 84/90, not 110
- board: story 2 marked ready, porch-2 row rewritten off the stale
wob.h/110 claim
