Build "ScriptArchive DAO" in ONE Lovable message. Single-page demo on the TON testnet.

CONCEPT
Preserve scripts onchain with collaborative DAO management and gasless transactions via social wallets.
Discipline: Theater & Live Performance (preservation).
Onchain primitive: TON Connect wallet. Why this primitive: TON Connect social enables decentralized governance; sponsored tx reduce cost barriers.

5-CREDIT BUDGET (HARD LIMIT)
- ONE single-page app. No router, no Lovable Cloud, no database, no auth beyond TON Connect.
- ONE FunC contract, <=60 lines, deployed to TON testnet and readable on tonscan.
- TON Connect is always the wallet layer (Tonkeeper, MyTonWallet, Tonhub).
- Pinata/IPFS only if the idea genuinely needs to store a file or metadata.
- At most ONE AI call per user action (Lovable AI Gateway with LOVABLE_API_KEY, if AI is part of the idea).
- Skip tests, skip CI, skip docs pages. Ship the demo, nothing else.

STACK
- React + Vite + TanStack Start, single page (the index route).
- SSR-safe wallet mount is MANDATORY. Never import @tonconnect/ui-react at module
  scope of a route file — it touches `window` and crashes SSR. Use
  lazy(() => import('./ton-client-entry')) inside <ClientOnly> + <Suspense>, and
  keep <TonConnectUIProvider> inside ton-client-entry.tsx only.
- Publish public/tonconnect-manifest.json ({ url, name, iconUrl }) and pass
  manifestUrl={`${window.location.origin}/tonconnect-manifest.json`}.
- TESTNET IS FORCED: send with `network: CHAIN.TESTNET` and refuse to submit when
  `wallet.account.chain !== CHAIN.TESTNET`, with a 'switch your wallet to testnet' hint.
- Amounts are nanotons as strings ("50000000" = 0.05 TON). A text-comment body is
  beginCell().storeUint(0, 32).storeStringTail(text).endCell().toBoc().toString('base64').
- Read chain state from the public indexer https://testnet.toncenter.com/api/v3
  (/transactions?account=…, /jetton/transfers?address=…). Never poll a wallet for history.
- Contracts live in /contracts, compiled with @ton-community/func-js and deployed with
  @ton/ton + @ton/crypto from a node script — keep them out of the Vite bundle.
- Persistent amber "TON testnet only · no real value moves here" banner at the top of the shell.

WALLET LAYER (the whole point of this build)
- TON Connect handles identity: no seed phrase typing, no browser extension required —
  desktop shows a QR, mobile deep-links straight into Tonkeeper.
- Surface four explicit states: not installed, connected, wrong network (mainnet), and
  transaction pending. Never silently retry a rejected transaction.
- Every preservation action is one `sendTransaction` with a text-comment payload, pinned to CHAIN.TESTNET.

CONTRACT (contracts/ScriptArchiveDAO.fc — FunC, compiled with @ton-community/func-js):
```func
;; ScriptArchiveDAO — Preserve scripts onchain with collaborative DAO management and gasless transactions via social wallets.
;; Built during the Creative AI & Quantum Hackathon organised by StreetKode Fam during Indian Krump Festival 14
slice begin_parse(cell c) asm "CTOS";
builder begin_cell() asm "NEWC";
cell end_cell(builder b) asm "ENDC";
cell get_data() asm "c4 PUSH";
() set_data(cell c) impure asm "c4 POP";
int slice_bits(slice s) asm "SBITS";

() recv_internal(int my_balance, int msg_value, cell in_msg_full, slice in_msg_body) impure {
    if (in_msg_body.slice_bits() < 32) { return (); }
    int op = in_msg_body~load_uint(32);
    if (op != 0) { return (); }            ;; text-comment messages only
    slice ds = get_data().begin_parse();
    int total = ds.slice_bits() >= 64 ? ds~load_uint(64) : 0;
    set_data(begin_cell().store_uint(total + 1, 64).end_cell());
}

int total_logs() method_id {
    slice ds = get_data().begin_parse();
    if (ds.slice_bits() < 64) { return 0; }
    return ds~load_uint(64);
}
```
The payload itself lives forever in the transaction history; the counter proves the
contract actually processed it. Deploy with a node script that builds
`contractAddress(0, { code, data: beginCell().storeUint(0, 64).endCell() })`, sends 0.05 TON
with `init`, then writes the address into src/data/ton.json.

USER FLOW
1. 'Connect Tonkeeper' -> address chip + testnet badge.
2. Directors act on their preservation; the wallet sheet shows the exact nanoton amount and comment.
3. The confirmed transaction appears in the feed with a tonscan link.
4. Footer renders: "Built during the Creative AI & Quantum Hackathon organised by StreetKode Fam during Indian Krump Festival 14"

TON SURVIVAL KIT (non-obvious rules — follow all of them)
1. BUFFER: browsers have no `Buffer`, but every TON lib returns one, so
   `cell.toBoc().toString("base64")` throws "Buffer is not defined". Add one helper and
   await it at the top of EVERY function touching @ton/core, @ton/crypto or @ton/ton —
   including the TON Connect path, which is the one people forget:
     export async function ensureBuffer() {
       const g = globalThis as typeof globalThis & { Buffer?: unknown };
       if (g.Buffer) return;
       g.Buffer = (await import("buffer")).Buffer;
     }
2. ADDRESS FLAVOURS: one key renders as four strings. `EQ…`/`UQ…` are the mainnet
   flavours (bounceable / non-bounceable), `kQ…`/`0Q…` are the test-network flavours.
   Never string-compare addresses across flavours — normalise first with
   `Address.parse(a).equals(Address.parse(b))`. Render with an explicit flavour:
     addr.toString({ testOnly: true, bounceable: false, urlSafe: true })
   Send user transfers NON-bounceable (`bounce: false`); a bounceable send to an
   uninitialised wallet returns the funds and the demo looks broken.
3. WALLET VERSION: the same mnemonic derives DIFFERENT addresses per wallet version.
   A 24-word TON phrase -> `WalletContractV4` (workchain 0); a 12-word BIP39 phrase
   (Gram, MyTonWallet) -> `WalletContractV5R1`. Derive both, query balances, and use
   the funded one — do not guess. A TON wallet is itself a contract: it needs ~0.05 TON
   and its first send carries `init` with `seqno: 0`. "Not deployed" is normal for a
   fresh address, not an error.
4. EXPLORER: link everything to https://testnet.tonscan.org/address/<addr> and
   https://testnet.tonscan.org/tx/<hash>. Derive the base URL from config, never hardcode.
5. WALLET REALITY CHECK: mobile Tonkeeper and Gram ship mainnet-only, so a test-network
   demo opened on a phone dead-ends with "your wallet is on TON mainnet". Ship a fallback:
   generate a throwaway wallet in the browser (`mnemonicNew()` from @ton/crypto, mnemonic
   in localStorage, funded from the faucet) and sign locally with `WalletContractV4`.
   Lock that browser-held key to the test network — never let it touch real funds.
6. TONCENTER: v3 rate-limits hard (HTTP 429). Wrap every read in a retry with backoff and
   send `X-API-Key: TONCENTER_API_KEY` on anything user-facing.
7. PAYMENT VERIFICATION: verify SERVER-side only, never trust a client-reported hash.
   Mint a one-time `chx-<hex>` memo, then match the recipient's recent transactions on
   amount >= price, decoded comment === memo, `transaction_aborted === false`, and a
   15-minute freshness window. Comments must be sent as a base64 BOC, not plain text:
     beginCell().storeUint(0, 32).storeStringTail(memo).endCell().toBoc().toString("base64")
8. SSR: mount TON Connect client-side only — `lazy(() => import("./ton-client-entry"))`
   inside `<ClientOnly>` + `<Suspense>`. Importing @tonconnect/ui-react at route module
   scope crashes the server render. `tonconnect-manifest.json` must sit at a public https URL.
9. INSTALL: npm i @tonconnect/ui-react @ton/ton @ton/core @ton/crypto buffer
   (add @ton-community/func-js only when you compile and deploy a FunC contract).
