The web server behind the graph UI is now a purpose-built in-house
module (src/ui/httpd.c): localhost-only listener, strict HTTP/1.1
parsing with fixed request caps, a per-connection receive deadline,
and Connection: close semantics. http_server.c keeps the routing and
handlers, rewritten against the new transport API; the public server
API and main.c are unchanged. The previously vendored third-party
server is removed entirely.
Comes with a new 28-test transport + routing suite (tests/test_httpd.c)
covering parsing edge cases (strict CRLF, Content-Length limits, raw
path matching, percent-decode rules) and live-socket behavior (CORS
policy, RPC dispatch, receive deadline, clean shutdown). The security
audit scripts now check the new file layout and treat any network call
in vendored code as a failure.
Minified JS in dist/ contains hundreds of string-constant URLs from
bundled npm libraries (React error pages, W3C namespace URIs, CDN
references, OSS credits) that are never fetched at runtime. Scanning
them produced an endless stream of false positives requiring per-URL
allowlisting.
Fix: split the A1 URL check by directory:
- src/ (our code): strict — any external URL is blocked
- dist/ (npm build output): skip inline URL scan entirely
Structural checks (A2-A6) still apply to dist/:
- External <script>/<link> loads in HTML
- Tracking/analytics identifiers
- Iframes, eval/Function, external WebSockets
- UI audit (L6): allowlist bundled framework URLs in dist/ (React error
URLs, W3C namespace URIs, Three.js credits, Google Fonts, Tailwind).
These are embedded by npm deps during Vite build, not our code.
- Binary strings (L2): skip URLs shorter than 15 chars — Windows binary
has byte sequences that strings(1) interprets as "https://H9" etc.
- Allow Google Fonts <link> in HTML (loaded by index.html for Inter/
JetBrains Mono fonts).
