PoCs Hub — Consolidated Demo Menu

Status: 🟡 In progress (2026-08-03) — nav shape decided, jay gave the go-ahead to build on branch claude/pocs-hub. /etc page, Card component (now shared as app/DemoCard.tsx), nav entry, ALLOW_ETC flag, and PUBLIC_PATHS entry are built and verified locally (pnpm build clean, dev-server smoke test). Testing locally only; deploy happens after jay's review. Full build log: 2026-08-03 history (search "PoCs hub").

Source: jay's request, 2026-08-03 — moved out of docs/tasks/current-plan.md (2026-08-03) so that file stays scoped to just AP2 + Account Abstraction (AA); the hub is supporting infrastructure those two plug into, not itself an AP2/AA task.

Goal (jay)

Stop growing the top nav one demo at a time. Add one top-menu item that's a landing hub — a card grid, each card linking to a real test/demo page, with a short description and a "how to run this" note — and fold the scattered technical demos (Hyperliquid Trading, PBS, AP2, AA, and future items) under it instead of each getting its own top-level menu slot.

This isn't a new idea — it's finishing one the plan already assumed. Several backlog items (see README.md — Zapier MCP, Solana, ERC-8141) already say their home is /etc or /etc/X — that route has been referenced since 2026-07-17 but was never actually built as a page or wired into app/Nav.tsx. This is "build the thing the plan already assumed existed."

Route & label

Route: /etc — reuses the slug already referenced across the backlog docs, so nothing else needs renaming.
Label — decided (jay, 2026-08-03): "PoCs" (overrode the "Tech Research" suggestion — shorter, and names exactly what these pages are: proofs-of-concept, not product features).

Hub page design (`/etc`)

Card grid (app/etc/page.tsx + the shared app/DemoCard.tsx, also used by TIL). Each card shows:

Title
One-line description — what it proves / what tech it demos
Status badge — Live or Coming soon
"How to run" — a short 2–4 step how-to (wallet? testnet? what to click), so a visitor can actually try it without reading the source
Link to the real page (enabled if live, disabled/greyed if not)

Initial card set:

Card	Links to	Status	How-to-run sketch
Hyperliquid Trading	`/market`	Live	Connect MetaMask → switch to HL testnet → claim mock USDC at the HL testnet faucet → place a small limit order
PBS (searcher / relay)	`/xyz`	Live	Submit a bundle via the searcher form (Sepolia) → watch the relay dashboard for inclusion
AP2 — Stripe settlement	`/ap2` (or `/etc/ap2`)	Coming soon — see current-plan.md §2	Click "buy" → Stripe test Checkout → pay with Stripe's test card `4242 4242 4242 4242`
AA — delegatable accounts & session keys	`/etc/aa`	Coming soon — see current-plan.md §3 + §6	Connect MetaMask on Sepolia → grant a scoped session key → watch it spend within the granted limit, no re-sign popup
Solana	`/etc/solana`	Coming soon — see README.md	(fill in once scoped)
Zapier MCP	`/etc/zapier`	Coming soon — see README.md	(fill in once scoped)
ERC-8141	knowledge page	Coming soon — see README.md	Read-only explainer — no wallet needed
Toss Payments	`/etc/toss` or `/ap2`	Coming soon — see README.md	Click "buy" → Toss test Checkout

Nav change — decided (jay, 2026-08-03)

Remove Market and XYZ as separate top-level app/Nav.tsx items — fold fully into the hub, no top-nav shortcut kept alongside the card (accepted the traffic/bookmark trade-off: /market and /xyz routes keep working, only the nav entry point changes). The bare /ap2 "coming soon" stub also retires once the AP2 Stripe example ships as a hub card.
Game and JayVerse stay top-level — not folded into PoCs; they're product/showcase demos, not the "test code" jay meant (Hyperliquid Trading / PBS / AP2 / AA). No change to their nav entries.
Label: "PoCs" — all open items from the design draft are resolved; nothing left blocking the build.

AA implementation stack — thirdweb vs. what's already decided

This design question came up while scoping the hub's AA card, but it's core AA planning, not hub plumbing — full reasoning lives in current-plan.md §6 (Agentic AA). Short version: MetaMask Delegation Toolkit stays for the 7702/7715 half (§3); thirdweb replaces ZeroDev/Pimlico for the 4337-pillars half (§6).

Sequencing

Build the /etc hub — page, Card component, nav entry. No new demo content required yet; the hub can launch listing Market + PBS as Live and AP2 + AA as Coming soon.
AP2 and AA get wired in as hub cards once each ships — see current-plan.md §5 for that build order.
