test: full Playwright + API test suite for stage

159 tests across three Playwright projects (api, chromium, mobile): - tests/api/security.test.ts: security headers, CORS on /api/supabase-config (origin allowlist enforced), auth gate on /api/demo, Stripe webhook signature enforcement, source file leakage, path traversal, input validation (8000-char message cap) - tests/api/endpoints.test.ts: /api/health, /api/founding-count shape invariants, /api/supabase-config JWT shape, sitemap.xml, robots.txt, /llms.txt, /api/soul-health internal gate, 404 for unknown routes - tests/e2e/landing.spec.ts: title, h1 count, meta description, OG tags, canonical (no stage leak), JSON-LD schema, demo widget DOM presence, JS error filtering (known GTM/CSP noise excluded) - tests/e2e/seo.spec.ts: per-page title patterns, noindex on checkout, canonical URLs, sitemap production-URL enforcement - tests/e2e/checkout.spec.ts: all three plan variants, auth section, payment element, canonical - tests/e2e/chat.spec.ts: widget DOM structure, auth gate (send button disabled without session), API-level auth rejection - tests/e2e/navigation.spec.ts: all public routes return 200, 404s for removed/old paths (/terms, /enterprise-terms, /gallery), static files All 159 pass against stage. CI step added to stage.yaml after smoke test.

Previously any unauthenticated POST could forge a payment_intent.succeeded event and increment the founding counter or trigger Supabase account provisioning for arbitrary emails. - CORS on /api/supabase-config: restrict to neurontechnologies.ai and localhost origins only. Cross-origin requests now get 403. - /api/soul-health: require X-Internal: true header; otherwise return 404. Endpoint was publicly accessible and leaked internal soul service URL, network topology, and raw probe responses. - Static asset / JS headers: add X-Frame-Options, Referrer-Policy, Permissions-Policy, and Content-Security-Policy to static_asset_headers_json and js_headers_json. These were only present on HTML/API responses before. - Fix state key bug: share_card_page read state_get("__neuron_origin__") but the key registered at startup is "__origin__", causing empty base URLs in share card og: meta tags.	2026-05-10 23:56:31 -05:00
will.anderson	fe418bf3f7	feat: auth-gate demo chat + budget circuit breaker Dev — Build & local smoke test / build-smoke (pull_request) Successful in 2m10s Details Gate the demo chat behind Supabase auth: the widget now fetches Supabase config on open, shows a compact sign-in pane (Google OAuth or email/password) when the user is unauthenticated, and passes the access_token to /api/demo. The server verifies the token via supabase_auth_user() before any processing and uses the verified user ID as the rate-limit key. Add a budget kill switch: a demo_config table in Supabase holds a demo_enabled flag that /api/demo polls every 60s (cached, fails open). A Cloud Function (demo-budget-guard) is triggered by a GCP Pub/Sub budget alert and sets demo_enabled = 'false' when spend crosses 90% of the $150 daily budget. Budget and topic are provisioned; function is live in us-central1.	2026-05-10 23:44:54 -05:00

After elb runs (and generates all intermediate .c files in dist/), recompile el_runtime.c with -DHAVE_CURL and relink the entire binary from those generated files.

will.anderson	0433fe8c0f	Fix http_response() truncating envelope via stale _tl_fs_read_len Dev — Build & local smoke test / build-smoke (pull_request) Failing after 2m22s Details http_response() builds a JSON envelope wrapping the body. If the caller previously called fs_read() (which sets _tl_fs_read_len = file_size), http_worker used that stale value as the response copy length — truncating the larger envelope to the original file size before it reached http_send_response. The truncated envelope had the body field cut mid-string; jp_parse_string_raw failed, env_body = "", and http_send_all sent file_size bytes of garbage past the empty string. Fix: reset _tl_fs_read_len = 0 at the start of http_response(). The hint was set for the raw file bytes; the envelope is a new string and must use strlen() for its length.	2026-05-10 19:23:10 -05:00
will.anderson	c99ca82302	Fix JS files served as raw JSON envelope instead of JavaScript Dev — Build & local smoke test / build-smoke (pull_request) Failing after 1m36s Details http_parse_envelope() called json_parse() on the entire response envelope (~47KB when body is obfuscated JS). The parser failed on large/complex content, so is_envelope=0 and the raw JSON was sent — browsers got {"el_http_response":1,...} instead of executable JavaScript, silently breaking all client-side code. Fix: replace json_parse-of-full-envelope with a direct field scanner: - "status" extracted via strtol - "headers" object extracted via brace-depth scan, then json_parse only that small substring (always safe — headers are simple k/v string pairs < 1KB) - "body" string extracted via jp_parse_string_raw — no intermediate allocation Also: /js/* route now returns http_response(200, js_headers_json(), content) with explicit Content-Type: application/javascript so the browser doesn't apply the json-heuristic (obfuscated JS starting with '[' was detected as JSON, which with X-Content-Type-Options: nosniff blocks script execution).	2026-05-10 17:32:45 -05:00
