+# Q‑Wallets v1.0.1 — Release Notes
+
+_Date:_ 2025‑08‑22
+
+## Summary
+
+This patch focuses on **address validation and send reliability** across supported chains, plus test/build stability. It removes the old “34‑character only” rule that blocked modern address formats (especially **bech32/SegWit**), and introduces per‑chain validators that match each network’s real rules. Litecoin now **auto‑converts M‑addresses to 3‑addresses** on send, and Pirate Chain (ARRR) shielded addresses are fully validated.
+
+## Highlights
+
+- ✅ **Modern address support**
+  - **BTC:** `1…`, `3…`, `bc1…` (SegWit/taproot) accepted.
+  - **LTC:** `L…`, `M…`, `3…`, `ltc1…` accepted; **M→3** conversion on send.
+  - **DGB:** `D…` (P2PKH), `S…`/`3…` (P2SH), `dgb1…` (bech32) accepted.
+  - **DOGE:** `D…` (P2PKH), `9…`/`A…` (P2SH) accepted.
+  - **RVN:** `R…` (P2PKH), `r…` (P2SH) accepted.
+  - **ARRR:** `zs…` (Sapling bech32 shielded) validated, with strict HRP & payload checks.
+
+- ✅ **UI/UX improvements**
+  - Litecoin send form shows **“Converted: 3‑ADDRESS”** underneath the input when an entered `M…` address is normalized for sending.
+  - Inline helper text displays **specific reasons** for invalid addresses instead of a generic “Unrecognized format.”
+
+- ✅ **Under the hood**
+  - Unified validators in `src/lib/validateAddress.ts` using **@scure/base** for bech32 and **base58check(sha256)** for Base58Check (pure browser‑safe).
+  - Added **ARRR** validator for `zs…` Sapling addresses (HRP `zs`, 43‑byte payload).
+  - Stabilized tests and fixed hangs/timeouts; Vitest runs to completion.
+
+## Background — What changed vs before?
+
+**Before:** A single hard length check (e.g., “must be 34 characters”) caused any **bech32** address (like `ltc1…` or `bc1…`) to be rejected, even though Qortal Core can send to them. LTC `M…` P2SH addresses also weren’t converted to the compatible `3…` form during send.
+
+**Now:** We perform **format‑aware validation**:
+
+- **Base58Check**: decode and verify checksum; check version bytes per chain (P2PKH/P2SH).
+- **bech32 / bech32m**: decode and verify checksum; check HRP per chain (`bc`, `ltc`, `dgb`, `zs`).
+- Per‑chain **version/HRP tables** replace fixed‑length checks.
+
+## Chain‑by‑chain details
+
+### Bitcoin (BTC)
+
+- **Accepted:** `1…` (P2PKH/0x00), `3…` (P2SH/0x05), `bc1q…` / `bc1p…` (SegWit bech32/bech32m).
+- **Validation:** Base58Check or bech32 HRP `bc`.
+- **UI:** Inline error reasons on failure.
+
+### Litecoin (LTC)
+
+- **Accepted:** `L…` (P2PKH/0x30), `M…` (P2SH/0x32), `3…` (P2SH/0x05), `ltc1…` (bech32).
+- **Auto‑convert:** When the user enters a **valid `M…`** address, we display **“Converted: 3‑ADDRESS”** and **send to the `3…`** equivalent, matching network tooling the community already uses.
+- **Validation:** Base58Check and bech32 HRP `ltc`.
+
+### DigiByte (DGB)
+
+- **Accepted:** `D…` (P2PKH/0x1e), `S…` (new P2SH/0x3f), `3…` (legacy P2SH/0x05), `dgb1…` (bech32).
+- **Validation:** Base58Check or bech32 HRP `dgb`.
+
+### Dogecoin (DOGE)
+
+- **Accepted:** `D…` (P2PKH/0x1e), `9…` / `A…` (P2SH/0x16).
+- **Validation:** Base58Check. (bech32 not in standard mainnet usage.)
+
+### Ravencoin (RVN)
+
+- **Accepted:** `R…` (P2PKH/0x3c), `r…` (P2SH/0x7a).
+- **Validation:** Base58Check.
+
+### Pirate Chain (ARRR)
+
+- **Accepted:** `zs…` **Sapling shielded** bech32 addresses only.
+- **Validation:** bech32 HRP `zs` with **43‑byte** payload (≈ 78 characters). Mixed‑case, wrong HRP, or bad payload length is rejected with specific reasons.
+
+## Developer Notes
+
+- **Core file:** `src/lib/validateAddress.ts`
+  - Exposes per‑chain helpers: `validateBitcoinAddress`, `validateLitecoinAddress`, `validateDigibyteAddress`, `validateDogecoinAddress`, `validateRavencoinAddress`, `validateArrrAddress`, and a generic `validateAddress(chain, addr, net)` switch.
+  - Base58Check: `@scure/base` **base58check(sha256)**; bech32/bech32m: `@scure/base`.
+  - LTC function `normalizeLitecoinAddressForSend(addr)` returns `{ ok, normalized?, reason? }` and is used in the LTC page to display the converted `3…` address and to pass the normalized recipient when sending.
+
+- **UI wiring:** Each coin page imports its validator and performs **live validation** on input. Error text shows a cause when available.
+
+- **Testing/CI:**
+  - Fixed long‑running/hanging tests; Vitest now completes consistently.
+  - Added coverage for BTC/LTC/DGB bech32 acceptance, LTC M→3 conversion, and ARRR `zs…` payload length checks.
+
+## Breaking/Behavior Changes
+
+- **Bech32 acceptance**: Many addresses that previously failed (e.g., `ltc1…`, `bc1…`) are now accepted as valid.
+- **LTC send path**: Enters `M…` → **sends to `3…`** automatically (visible in the UI).
+- **Error messaging**: Invalid input now returns useful reasons (e.g., “wrong HRP”, “unexpected version byte”, “unexpected payload length”).
+
+## Known Limitations / Next
+
+- **Theme detection from Qortal Hub**: deferred to the next release.
+- **ARRR future encodings** (e.g., Orchard/unified if adopted) can be added later.
+- **Network toggles**: Our validators default to mainnet constants; testnet rules can be widened in a follow‑up.
+
+## Upgrade notes
+
+- No data migrations.
+- After pulling the update, run `npm i` once to ensure the lockfile includes `@noble/hashes` if your env requires it, then `npm run build`.

+# Q‑Wallets v1.0.1 — What’s new for you
+
+We fixed address validation so you can send to **modern addresses** reliably.
+
+## The big changes
+
+- **Bech32/SegWit works now**  
+  Send to `bc1…` (Bitcoin), `ltc1…` (Litecoin), and `dgb1…` (DigiByte) addresses. These used to be blocked by an old 34‑character rule.
+
+- **Litecoin “M” addresses auto‑convert**  
+  If you paste a valid `M…` Litecoin address, the wallet shows **“Converted: 3‑ADDRESS”** and sends to the compatible `3…` form automatically.
+
+- **Pirate Chain (ARRR) shielded addresses**  
+  `zs…` addresses are fully supported and validated.
+
+- **Clear error messages**  
+  If an address is invalid, you’ll see why (e.g., wrong prefix or checksum) instead of a generic error.
+
+## Supported address types (quick list)
+
+- **BTC:** `1…`, `3…`, `bc1…`
+- **LTC:** `L…`, `M…`, `3…`, `ltc1…` (with **M→3** auto‑conversion)
+- **DGB:** `D…`, `S…`/`3…`, `dgb1…`
+- **DOGE:** `D…`, `9…`/`A…`
+- **RVN:** `R…`, `r…`
+- **ARRR:** `zs…` (shielded)
+
+No extra setup needed — just update and you’re good to go.

+# ADR 0001 — Decoder‑based Address Validation
+
+## Context
+
+Users reported failures sending to `ltc1…` SegWit addresses despite Qortal Core support. The UI enforced **34‑character** addresses and lacked proper decoding.
+
+## Decision
+
+Adopt **decoder‑based validation** per chain:
+
+- Try **Base58Check**; verify version bytes & payload length.
+- Else try **Bech32/Bech32m**; verify HRP, checksum, witness program rules.
+- For **Qortal** addresses, use Core endpoint **GET /addresses/validate/{address}**.
+- Return structured errors; remove length constraints from inputs.
+
+## Consequences
+
+- Accepts modern formats (`ltc1…`, `bc1…` etc.).
+- Precise error messages; fewer false positives.
+- Shared util reduces duplication; testable in isolation.
+
+## Status
+
+**Accepted** (to be implemented in v1.0.1).

+# ADR 0002 — CI & Testing Baseline
+
+## Context
+
+Repo lacked tests and CI. We need reliable gates before shipping validation changes.
+
+## Decision
+
+- Add **Vitest + RTL** with coverage thresholds (lines/branches/functions/statements: 70/70/50/70).
+- Add **Gitea Actions** workflow at `.gitea/workflows/ci.yml` with steps: install → lint → typecheck → build → test.
+- Introduce ESLint/Prettier and `npm` scripts for linting and testing.
+
+## Status

+# Architecture — Q‑Wallets
+
+## Stack
+
+- **React + TypeScript** built with **Vite**
+- **MUI** for theming/components
+- Routing via React Router
+- Coin pages under `src/pages/<coin>/index.tsx`
+
+## Data Flow (today)
+
+- Each coin page handles fetching balances, transactions, and **send** actions via Qortal Core / coin‑specific RPCs proxied by Hub.
+- Form validation is currently **UI‑level** and (bug) uses **length checks** for addresses.
+
+## Planned Shared Utilities
+
+- `src/lib/validateAddress.ts` — unified decoder‑based validation for all supported chains.
+- `src/lib/networks.ts` — chain/network params (HRPs, version bytes, regex fallbacks as last resort).
+
+## Theming
+
+- Today: MUI `ThemeProvider(createTheme(...))` in `App.tsx`.
+- Planned: `useHubTheme` hook listening to parent `postMessage` (`QORTAL_THEME`) and mapping to MUI palette mode; fallback to system.
+
+## Error Handling
+
+- Standard toast/snackbar for success/fail.
+- Distinguish user errors (bad address/amount) vs network errors.

+# Coding Instructions — Root Guide (Q‑Wallets)
+
+_Last updated: 2025-08-21_
+
+This guide sets our baseline for collaboration across Q‑Wallets. It mirrors your global standards and adds repo‑specific notes.
+
+## Communication & Flow
+
+- Propose a plan → execute in **small slices**.
+- Ship **tests with every change**; fix red before new work.
+- Capture decisions as **ADRs**; capture insights in **Living Memory** (docs/roadmap.md or ADR appendix).
+- Keep the repo tidy: remove dead code; update docs/tests with code changes.
+
+## Source Control
+
+- Small, atomic commits; meaningful messages.
+- Pre‑commit: Husky + lint‑staged (when added).
+- Always run: `npm run lint && npm run typecheck && npm test` locally before a PR.
+
+## Test Strategy
+
+- **Unit/Component:** Vitest + React Testing Library + jsdom.
+- **E2E:** Playwright (later) with MSW for network mocking.
+- Coverage targets (CI‑enforced): **lines 70, branches 70, functions 50, statements 70**.
+- Conventions:
+  - Co‑locate tests as `*.test.ts(x)` under `src/`.
+  - Provide `src/test/setup.ts` for RTL config and polyfills.
+  - Use `vi.mock()` for unstable or network‑bound deps.
+  - Wrap state updates in `act`/`waitFor`; avoid flakiness.
+
+## CI/CD
+
+- Default CI: **Gitea Actions** (self‑hosted OK). GitHub Actions is acceptable if mirrored.
+- Pipeline (see project‑instructions for the YAML path):
+  1. Checkout
+  2. Install Node (official tarball)
+  3. `npm ci`
+  4. Lint (`npm run lint`)
+  5. Typecheck (`npm run typecheck` or `tsc -b --noEmit`)
+  6. Build (`npm run build`)
+  7. Test with coverage (thresholds enforced)
+- Cache installs if available; publish coverage artifacts if supported.
+
+## UX Status & Feedback
+
+- Loading: skeletons/spinners with labels.
+- Success: brief toast/snackbar or inline confirm.
+- Error: actionable messages + retry; avoid generic “failed”.
+
+## Debug & Support
+
+- Dev‑only debug menu (or hotkey) to copy diagnostics, recent logs, app version.
+- No secrets/PII in logs.
+
+## Performance
+
+- Virtualize large lists, avoid N+1 calls.
+- Windowed fetching + backoff; cache where safe.
+
+## Security
+
+- No hardcoded secrets; env‑driven config.
+- Sanitize inputs (addresses/amounts) and validate before send.
+- Minimal logging; never log private keys or seed phrases.
+
+## Documentation
+
+- Keep `docs/architecture.md`, `docs/testing.md`, `docs/project-instructions.md` current.
+- Write ADRs for policy or interface changes.
+
+## Packaging & Verification (Standard Drop)
+
+- Provide a small zip of changed files.
+- Include a short “change → verify” note and commands to run audits/tests.

+## Troubleshooting: npm ci lockfile drift
+
+If you see errors like:
+
+- `npm error code EUSAGE` and messages about the lock file not satisfying package.json
+- "Invalid: lock file's X does not satisfy Y" or "Missing: Z from lock file"
+
+**Fix:** refresh the lock file once locally:
+
+```bash
+npm run --silent --prefix scripts true 2>/dev/null || true
+bash scripts/refresh-lock.sh
+# on Windows PowerShell:
+# scripts/refresh-lock.ps1
+```
+
+After this, `npm ci` should work again in CI. The CI workflow also auto-falls back to `npm install` if `npm ci` fails.
