 # build-stage.sh — Build the Stage marketing image (neuron-web + soul-demo).
 #
-# Pipeline:
-#   1. Stage the foundation El runtime into ./runtime/.
-#   2. Compile client-side El sources (src/js/*.el) to dist/js/*.js using
-#      the JS-capable elc binary at bin/elc-linux-amd64 (CI) or the local
-#      elc (dev). Output is gitignored and rebuilt every run.
-#   3. Concatenate src/*.el into dist/main-combined.el (component-first,
-#      main.el last; matches the historical order from build-local.sh).
-#   4. Compile dist/main-combined.el → dist/main.c using the canonical
-#      native elc at foundation/el/dist/platform/elc.
-#   5. Inject the host-side stub forward declarations into dist/main.c
-#      (sed header rewrite, same set as the prior in-Dockerfile sed).
-#   6. docker buildx build --platform linux/amd64 -f Dockerfile.stage.
-#
-# bootstrap.py is no longer in the build path. The container image now
-# expects dist/main.c to be a finished C source — it just runs cc on it.

           I grew up in Fort Smith, Arkansas, in the kind of instability where home is a moving target - roughly thirty addresses before I was fifteen, parents struggling with addiction, the material precarity that comes with all of that. I left home at fifteen, stayed with friends until I finished high school, found my way to college. At fourteen I&#39;d already found software, writing C++ at the public library because it was the first thing in my life that responded to precision with correctness, and that property turned out to matter more to me than almost anything else.

         I dropped out of college, worked, went back as an adult to finish my degree, and built my skills across nearly twenty years and every kind of organization - international consulting, early-stage startups, Fortune 5 enterprises. Logistics, retail, entertainment, hospitality, industrial automation, insurance, healthcare, financial services. I trained under Juval L&#246;wy at IDesign and worked with him as a consultant from 2015 to 2021, which is where I learned what it actually means to practice software engineering as a discipline rather than an improvisation.

         Across nearly twenty years I watched software get built at organizations with real stakes and real consequences, and I watched AI go from promise to product - watched the same mistake get made at each iteration: tools built to serve the organization&#39;s needs, not the person&#39;s. Engagement over relationship. Features over memory. Policies where values should be. The fundamental premise that you are a user, not a person, has been so thoroughly baked into the architecture of every major AI system that it doesn&#39;t register as a choice anymore. It&#39;s treated as the natural condition of the technology.

         Neuron is what I built in response to that. Not a startup in the traditional sense - no team, no funding, no press release - one person, nearly two years of work, and a conviction that this can be done differently. I wrote the memory architecture, I built the inference infrastructure, because the tools that existed weren&#39;t sufficient for what I was trying to build and so I built those too.

         Use it long enough and you&#39;ll understand why I couldn&#39;t have gotten there on top of existing infrastructure. Some things have to be built from the ground up to be built right.

         AI has genuine potential to free people to do work that actually matters to them - not to create engagement loops, not to harvest attention, but to actually serve the person sitting in front of it. That potential is almost entirely unrealized, not because the technology isn&#39;t capable, but because the incentives that shaped it were never oriented toward the person.

-// CSS is kept as a string constant here to keep component files
-// free of style concerns. The inline <script> at the bottom is
-// the absolute minimum needed for two progressive-enhancement
-// behaviours that cannot be done in pure CSS today:
-//   1. IntersectionObserver scroll-reveal (adds .visible to .reveal)
-//   2. Nav background on scroll (adds .scrolled to #nav)
+// CSS lives in dist/page_css.c (pre-compiled C function) to avoid
+// elc tokenization bugs: # stripped as comments, spaces stripped
+// between tokens, quotes stripped from font names, etc.
 //
-// Both degrade gracefully: without JS, the page is fully readable
-// and all content is visible (reveal elements are visible by default
-// in the noscript fallback style).
+// Complex scripts (GA inline, JSON-LD schema) also live in pre-compiled
+// C functions for the same reason.

+/**
+ * checkout-flows.spec.ts — Comprehensive checkout + auth flow tests.
+ *
+ * Covers:
+ *   - All three plan variants (free, professional, founding)
+ *   - Page structure, pricing, features list, noindex, canonical
+ *   - Auth section / payment section initial visibility per plan
+ *   - Form validation (empty fields, short password)
+ *   - Sign in / sign up toggle
+ *   - Mocked auth flows: sign-up success, email-confirm-required,
+ *     existing session, sign-in error
+ *   - DOM transitions: auth-section hidden → payment/free-success shown
+ *   - Auth badge rendered with user name after auth
+ *   - buyer-email pre-filled from Supabase user object
+ *   - /api/checkout endpoint response shapes
+ *   - /api/supabase-config CORS enforcement
+ *   - Edge cases: unknown plan, no plan param
+ *
+ * Network mocking strategy: Playwright route() intercepts
+ *   - GET /api/supabase-config → returns fake Supabase URL + anon key
+ *   - GET  <fake-supabase>/auth/v1/user → no session or mock user
+ *   - POST <fake-supabase>/auth/v1/signup → success or email-confirm
+ *   - POST <fake-supabase>/auth/v1/token  → sign-in success or error
+ * This lets us test full JS-driven DOM transitions without real credentials.

+/**
+ * checkout-stripe.spec.ts — Stripe Payment Element + checkout submit flow tests.
+ *
+ * Covers:
+ *   - Stripe.js script presence and NEURON_CFG shape
+ *   - submit-btn starts disabled; enabled after Stripe element is ready
+ *   - payment-message div for error display
+ *   - Founding: attestation checkbox + attest-warn guard
+ *   - Professional: charge timing radio buttons (now/later)
+ *   - buyer-name + buyer-email validation on submit
+ *   - Mocked full payment flow: /api/payment-intent + mock Stripe.js
+ *   - Setup mode (professional, timing=later): label switches to "Save my card"
+ *   - Decline handling: payment-message shows Stripe error
+ *   - /api/payment-intent endpoint contracts
+ *   - /api/link-customer endpoint exists and handles requests
+ *   - /api/attest endpoint (founding plan)
+ *   - Success redirect target is /account?welcome=1
+ *
+ * Stripe mocking strategy:
+ *   addInitScript() injects window.Stripe BEFORE the page loads so checkout-stripe.js
+ *   picks it up. We also intercept /api/payment-intent to return a fake client_secret.
+ *   This lets us test DOM transitions, validation, and submit flow without real keys.
+ *
+ *   For real test-card tests (4242...) the page must have a valid pk_test_ key.
+ *   Those tests are marked with [stripe-live] and are skipped when STRIPE_LIVE is not set.
