Who: Lena Park, 16, 11th grade Algebra 2. Nine days of flu. First night back.
Barrier: The worksheet treats three marks taught in her absence — (b/2)², √(−1), i — as already in her hands. Existing tools restart the unit or finish the homework. Both leave her locked out of tomorrow’s class.
What changed: Relink names only those marks, teaches them in this page’s notation, makes you use each move on problem 2, then you write the next line. Relink does not write it.

Demo

1. Judges: open https://ethaenall.github.io/relink/ — Lena’s page, no login, no model.
2. Tap each rust wave. Apply the move on problem 2. Write x² + 8x = −20. Relink does not write it.
3. Optional: https://ethaenall.github.io/relink/open/ — load Physics/Calculus, paste, or upload.

Stack

• Next.js 14 (App Router) + TypeScript + Tailwind
• Newsreader (worksheet) + Geist (chrome)
• Local kernel + authored seeds. No API required. See HOSTING.md to attach Featherless later. No keys live in this repo.

Built vs mocked

Path	Status
/ and /demo /lena	Fully built. Offline Lena demo. This is the judge path.
/open	Fully built. Load a page, paste, or upload. Local.
Physics sample	Fully built. Local seed lib/priya.ts.
One-pager, disclosures	Fully built.
GitHub Pages	Fully built for every static route.
/api/diagnose	Built in source. Optional. Not required. Stripped on Pages.
Chat tutor, gradebook, LMS	Not in scope.

Setup

npm install
npm test
npm run dev

Open http://localhost:3000

Tests

npm test

• check-copy — cards cannot use shame phrasing
• check-seed — Lena and Priya apply-to-#2 + next-line
• check-loop — ApplyCheck / NextLine types
• check-normalize — unicode next-line accept
• check-from-paste / check-kernel — samples name marks

Disclosures

See /disclosures.

AI tools

• Hermes Agent (Grok 4.6 via xAI) — coding assistant during the build window
• Featherless AI — optional, not used on / or /demo

Datasets

• None. All pedagogical content is original to this repo.

Why this shape

The prompt asks for one named person and one narrow barrier. The demo is that page. The tool is the same linker on any page Relink can name, including the Physics resource.
