docs(sso): document the silent single sign-on mechanism (0.1.26)

Login.tsx now attempts a credential-less silentLogin when an app sends the user
to the authorize page (client_id + redirect_uri present). IAM's Login handler
mints an auth code from the existing iam_session_id cookie (its already-signed-in
branch), so the 2nd/3rd app logs in seamlessly with no form. Falls back to the
interactive form when there is no live session. Backend already supports this;
this wires the SPA leg. Contract locked in client.test.ts (no creds posted,
redirect built from minted code; { error } -> form fallback).

-## Overview
-White-label login portal for Hanzo IAM - forkable, multi-tenant, RFC-compliant OAuth2/OIDC
+## Social login (GitHub/Google) — single-provider state + matched redirect_uri (fixed 0.1.24 → 0.1.25)
 
-## Tech Stack
-- **Language**: TypeScript/JavaScript
+The social hop used to fail at the IAM `/callback` exchange — GitHub with
+**"The provider: hanzo-iam does not exist"**, Google with "password or code is
+incorrect". TWO independent bugs, both in the SPA's provider-name handling; the
+IAM backend, the OAuth creds, and the registered redirect_uri were all fine.
+
+**Bug A — wrong provider IDENTITY (fixed 0.1.24).** `parseAppLogin`
+(`pkgs/auth/src/client.ts`) read the **outer** Casdoor app-provider LINK `name`
+as the provider identity. `get-app-login` returns each provider as a link object
+`{name, canSignIn, …, provider:{name, type, clientId, …}}`; the REAL identity is
+the nested `provider.name` (e.g. `provider-github`), the name the backend
+resolves with `GetProvider(admin/<name>)`. The outer link `name` can be a
+per-app label. Fix: derive from the **nested** `rec.provider.name`, falling back
+to the outer `rec.name` only when there is no nested record.
+
+**Bug B — TWO `provider=` in the state (fixed 0.1.25).** The console→hanzo.id
+SSO SDK appends `provider=hanzo-iam` (its per-org IDP hint) to the upstream
+`/login/oauth/authorize` query. `social.ts::buildProviderAuthUrl` then appends
+the REAL social `provider=provider-google`, so the base64 `state` carried BOTH.
+`Callback.tsx` recovers the provider with `URLSearchParams.get('provider')` —
+which returns the **FIRST** match (`hanzo-iam`), NOT the last — so the exchange
+POSTed `provider=hanzo-iam` and the backend rejected it. (The earlier "backend
+reads the LAST param" note was WRONG: the SPA reads the first.) Fix:
+`buildProviderAuthUrl` strips any pre-existing `provider=` from the upstream
+query (`baseQ.delete('provider')`) before appending the real one, so the state
+carries **exactly ONE** `provider=`. One provider, one source of truth — no
+reliance on parameter ordering. Locked in `pkgs/auth/src/social.test.ts`
+("a pre-existing provider= … is stripped — state carries exactly ONE provider").
+
+**redirect_uri consistency (hardened 0.1.25).** The hop builds the provider
+`redirect_uri` from `tenant.oauthCallbackOrigin` (the provider's REGISTERED
+callback host, `https://iam.hanzo.ai`, shared across brand portals).
+`client.providerLogin` POSTs that redirect_uri to IAM, which forwards it
+**verbatim** to the provider's token endpoint (`auth.go` →
+`GetIdProvider(idpInfo, authForm.RedirectUri)` → `Config.Exchange`); a mismatch
+→ `invalid_grant`. It now derives from the SAME `oauthCallbackOrigin` (was
+`publicOrigin`, the brand host — equal on the callback host today, but they
+diverge whenever a brand shares the iam.hanzo.ai client). Locked in
+`client.test.ts` ("providerLogin posts redirectUri from oauthCallbackOrigin").
+
+**RC#2 verified live (no Google account needed).** A junk-code probe of the live
+social path — `POST iam.hanzo.ai/v1/iam/login` with `provider=provider-google` +
+a fake code — returns `oauth2: "invalid_grant"`, NOT `invalid_client`. That
+proves Google **accepted** the client_id + client_secret and the
+`https://iam.hanzo.ai/callback` redirect_uri (client auth passed; only the fake
+code was rejected). So the Google clientId/secret in the running IAM are real
+and valid, the provider resolves + is enabled for `hanzo-console`, and the
+redirect_uri matches — the exchange will complete with a real Google code. No
+OAuth developer-console change is needed. The only thing not exercisable without
+a real Google/zoo.ngo account is the final code→user round-trip itself.
+
+## Silent single sign-on — auto-continue authorize from the issuer session (0.1.26)
+
+Sign in ONCE at the portal; every other app that authenticates through the same
+issuer host then logs in with NO form and NO credential re-entry. The IAM
+backend already supported this — its `Login` handler
+(`hanzoai/iam controllers/auth.go`) has an "already signed in to IAM" branch:
+when the request carries the `iam_session_id` cookie but NO username/password
+and NO provider, `GetSessionUsername()` is non-empty so it mints an
+authorization code via `HandleLoggedIn` straight from the session. The missing
+leg was the SPA: `Login.tsx` always rendered the login form, even with a live
+session.
+
+The fix wires the SPA leg. `Login.tsx` now, when an app sends the user to the
+authorize page (`client_id` + `redirect_uri` on the query), first calls
+`client.silentLogin(...)` — a credential-less POST to `/v1/iam/login`
+(`type:code`, `application`, NO username/password, `credentials:'include'`). If a
+live issuer session exists IAM returns the code and the SPA redirects straight
+back to the app (`redirect_uri?code=…&state=…`); if there is no session IAM
+answers `status:error` and the SPA falls back to the interactive form — never a
+dead end. A bare portal visit (no `client_id`/`redirect_uri`) has nowhere to
+redirect, so it shows the form immediately as before.
+
+In Hanzo IAM the OAuth `client_id` IS the application name (`hanzo-console`,
+`hanzo-chat`, …), so the SPA passes `application = client_id` with no extra
+lookup. The silent leg rides the SAME `HandleLoggedIn` as password/social, so it
+inherits the social-login `client_id`-resolution fix (`iam` ≥ v1.25.3) — without
+it the silently-minted code would carry an empty `client_id` and fail the
+downstream token exchange with `invalid_client`.
+
+Proven end-to-end against live IAM (no UI needed): a session-cookie-only POST to
+`/v1/iam/login` returns `status:ok` + a code, and that code exchanges at
+`/v1/iam/oauth/access_token` (with the PKCE verifier) for a real
+`access_token`+`id_token`+`refresh_token` — i.e. an existing session silently
+yields a usable token for another app. Contract locked in
+`pkgs/auth/src/client.test.ts` ("silentLogin posts NO credentials and redirects
+with the minted code"; "returns { error } when there is no session").
+
+Issuer-host note: SSO shares the `iam_session_id` cookie across apps only when
+they funnel auth through the SAME login host. Today both console
+(`IAM_SERVER_URL=iam.hanzo.ai`, which 302s to hanzo.id) and chat
+(`OPENID_ISSUER=hanzo.id`) land on the hanzo.id SPA, where the cookie lives — so
+the session is shared. `chat` has `OPENID_AUTO_REDIRECT=false`, so the user
+clicks "Log in with Hanzo" once (provider selection, not a credential prompt);
+set it `true` for fully zero-click entry into chat.
+
+## Org-wide unified login — declare the provider set once per org (iam)
+
+Enabling the same social/SSO set across an org's many apps is now ONE place:
+the org-level `Organization.DefaultProviders` (hanzoai/iam
+`object/organization.go`). Any application whose own `Providers` list is EMPTY
+inherits the org's `DefaultProviders` — resolved in the single app-read path
+`extendApplicationWithProviders` (`object/application.go`), so every app shares
+one provider set without repeating it. An app may still pin its own `Providers`
+to override. `init_data` adopts `DefaultProviders` onto an existing org
+additively (`initDefinedOrganization`, `initDataNewOnly` — like languages),
+never overwriting. The seed (`universe/infra/k8s/iam/init_data.json`) declares
+`defaultProviders` once per org and leaves per-app `providers: []`.
+
+**Enable unified login for a NEW org/tenant:** add the org to `init_data.json`
+with `defaultProviders: [provider-github, provider-google, provider-web3,
+provider-apple]` (or any subset) and leave each app's `providers: []`. All apps
+inherit automatically — no per-app reconfiguration.
+
+## Org-agnostic password login (fixed 0.1.23)
+
+The portal login is now **org-agnostic**: it no longer pins
+`organization=<brand>` on `POST /v1/iam/login`. `LoginForm` passes
+`tenant.loginOrg` (a NEW, normally-UNSET `TenantConfig` field) as the
+`organization`, and `client.login()` OMITS the field entirely when it is
+empty/undefined. With no org posted, IAM runs its **cross-org resolution**
+(`object.GetUserByFields` → `GetUserByFieldCrossOrg`) and the session encodes the
+user's REAL owner-org (`GetOrganizationByUser`), never the posted hint.
+
+Why this matters (the bug it fixes): IAM's `IsGlobalAdmin()` is
+`user.Owner == "admin"` (it ignores the stored `isGlobalAdmin` column), and
+`get-organizations` returns ALL orgs only for a global admin, else just the
+caller's own org. The seeded superusers (`z@hanzo.ai`, `a@hanzo.ai`,
+`woo@lux.network`) exist in BOTH the `admin` org (the global identity) AND their
+brand org (`hanzo/lux`). Pinning `organization=hanzo` made `GetUserByFields`
+hit the colliding `hanzo/z` row FIRST (in-org lookup succeeds → cross-org
+fallback never runs), so an admin got a 1-org `hanzo` session via the UI even
+though the API could reach the 45-org global session. Omitting the org makes the
+in-org lookups miss → cross-org fallback → `admin/z` (global) for the colliding
+hanzo-domain emails, while a brand-only identity (`z@lux.network`,
+`major@hanzo.ai`, …) still resolves to its own org. Verified live on
+`hanzo.id`: `z@hanzo.ai` → `owner=admin`, 45 orgs; a brand-only user → 1 org.
+
+Boundaries (do NOT regress):
+- **Signup** still sends a concrete `organization` (`tenant.orgId`) — you cannot
+  create a user in "no org". Only LOGIN omits it.
+- **Per-app SSO** (console/chat/team pass their own `client_id` + `redirect_uri`)
+  is unaffected: `type=code` + the app's client_id still flow; the auth code is
+  bound to the cross-org-resolved user. Proven against live IAM with
+  `application=hanzo-console`.
+- A brand that deliberately wants single-org portal login can set `loginOrg` in
+  its runtime catalog entry (`id-tenant-catalog` ConfigMap) — no rebuild.
+- Contract locked in `pkgs/auth/src/client.test.ts` (omit-when-unset,
+  omit-when-empty, include-when-set, SSO still omits, signup still sends).
+
+## PKCE on password login (fixed 0.1.13)
+
+`client.login()` (POST `/v1/iam/login`) must forward `code_challenge`
+/`code_challenge_method` on the QUERY string, exactly like `authorize()`.
+IAM's Login handler (`hanzoai/iam` `controllers/account.go`) reads
+`code_challenge` from the query first, body fallback, then threads it into
+`GetOAuthCode` so the minted code stores the challenge. Omitting it makes
+IAM store an EMPTY challenge; the downstream public SPA client (e.g.
+`hanzo-platform`) then fails token exchange with
+`token.CodeChallenge: empty` → `invalid_client` (it falls back to a
+client_secret check the public client can't satisfy — see
+`object/token_oauth.go:809-844`: with a non-empty stored challenge AND no
+client_secret sent, the secret check is bypassed). Social login was never
+affected (it rides `authorize()`). Plumb the URL's `code_challenge`
+through Login page → LoginForm → `client.login()`; do NOT default a
+challenge — only forward what the downstream OAuth request put on the URL.
+
+Known SEPARATE blocker (NOT this repo): after a 200 token exchange,
+platform's `/v1/iam/session` (`hanzo/platform` `pkg/platform/src/lib/iam.ts`
+→ `@hanzo/iam/server` `getServerSession`) returns 401 "Invalid IAM token"
+for a valid `aud:[hanzo-platform]` RS256 JWT signed by `cert-hanzo` (key IS
+in hanzo.id JWKS; the duplicate `cert-hanzo` entry is identical, harmless).
+That is a platform/SDK-side verification bug, tracked separately.
+
+## What this is
+
+White-label login + identity verification portal. Vite SPA, served from
+the Hanzo K8s cluster, white-labels per hostname.
+
+Replaces:
+- `~/work/hanzo/hanzo.id-worker` (Cloudflare Worker) — being decommissioned
+- `~/work/hanzo/id/legacy-nextjs/` (Next.js 15) — frozen, kept for diff

+
+`iamUrl` is the brand's OWN `*.id` host, NOT `iam.hanzo.ai` (HIP-0111:
+discovery must be host-relative or the SDK resolves to the IAM SPA HTML
+catch-all). One backend serves every brand behind its issuer host.
+
+## Auth methods — the full set
+
+Email/password + email/SMS code + GitHub + Google + Web3 (wallet). The enabled
+set is read LIVE from `/v1/iam/get-app-login` (`AuthClient.getAppLogin`), which
+mirrors each `-id` app's provider config in
+`universe/infra/k8s/iam/init_data.json`. Password sign-in goes through the IAM
+REST `login` and returns an auth code directly. Both honor a downstream
+`redirect_uri`.
+
+### Social providers — render only when configured; redirect via the "hop"
+
+`SocialButtons` renders ONLY providers IAM holds a REAL credential for
+(`AppProvider.configured` = non-placeholder clientId). With the seed's
+placeholders every social button is hidden, so a user never hits a dead-end;
+they reappear automatically once real creds land. Clicking a configured OAuth
+provider runs the **hop** (`social.ts::startProviderLogin`), which redirects
+straight to the provider with a base64 `state` that round-trips the original
+authorize request — matching the IAM (Casdoor) `getAuthUrl` contract. The
+provider returns to `/callback`; `Callback.tsx` detects the provider state and
+calls `client.providerLogin` to exchange the code at the IAM backend, then
+follows the continue-URL (which re-enters `/callback` as the normal OIDC code).
+(NOT `@hanzo/iam` `signinRedirect` — that loops back to the login page.)
+
+**To ENABLE real social login (the only remaining work):**
+1. Register an OAuth app per provider (GitHub/Google) with callback
+   **`https://<brand>/v1/iam/callback`** AND the app authorize redirect
+   `https://<brand>/callback` (per brand host: hanzo.id, lux.id, pars.id …).
+2. Put the client id/secret in KMS at **project `hanzo-iam`, env `prod`**, keys
+   `IAM_GITHUB_CLIENT_ID` / `IAM_GITHUB_CLIENT_SECRET` (and `IAM_GOOGLE_*`). The
+   `iam-kms-sync` KMSSecret (`universe/infra/k8s/iam/secret.yaml`) syncs that
+   path into `iam-secrets`; init_data.json substitutes `${IAM_GITHUB_CLIENT_ID}`
+   at deploy. The whole sync + env-ref chain already exists — today those keys
+   just hold placeholder values, so providers read as unconfigured (buttons
+   hidden). Replace the values; nothing else to wire.
+3. The buttons appear automatically (no portal change). **Live-verify** the
+   round-trip reaches the provider and completes — the hop + exchange are wired
+   and unit-tested (`pkgs/auth/src/social.test.ts`) but can only be exercised
+   end-to-end once real creds exist.

+
+## Why this layout (and not just Next.js)
+
+1. **Vite > Next.js for an SPA.** No SSR needed; auth is post-load only.
+   ~200kb gzip vs ~600kb. Build is 3s vs 90s.
+2. **@hanzo/gui v7 is the canonical UI.** Same shell as every other
+   Hanzo admin surface. No bespoke components.
+3. **Per-org brand packages.** `@hanzo/brand`, `@luxfi/brand`,
+   `@zooai/brand`, `@parsdao/brand` already ship `brand.json` files;
+   we fetch them at runtime. Adding a brand = `pnpm add @newco/brand`
+   + one line in `pkgs/shared/src/tenant.ts` (or a runtime catalog
+   entry — no rebuild).
+4. **Provider-pluggable IDV.** Same surface for Persona, Onfido, Veriff,
+   custom backends. No vendor lock-in at the portal layer.
+5. **Mirrors downstream tenant id-app forks.** Same `apps/` + `pkgs/`
+   pattern, same `@hanzo/gui` shell, same per-tenant brand resolution.

 ```
 
-## Key Files
-- `README.md` -- Project documentation
-- `package.json` -- Dependencies and scripts
-- `Dockerfile` -- Container build
+## Adding a new brand
+
+1. `pnpm add -F @hanzo/id-web @newco/brand`
+2. Add `TenantConfig` for the hostname in `pkgs/shared/src/tenant.ts`
+   (or put it in `IAM_TENANT_CONFIG_JSON` at runtime — no rebuild).
+3. Add the hostname to `BRAND_PACKAGES` in `apps/web/vite.config.ts`.
+4. Add host + TLS secret to `apps/web/k8s/ingress.yaml`.
+5. DNS → cluster ingress IP.
+
+## Plugging an IDV provider
+
+```ts
+import { registerProvider, createPersonaProvider } from '@hanzo/id-idv'
+registerProvider(createPersonaProvider({ templateId, apiKey, environment: 'production' }))
+```
+
+## Pre-built providers
+
+| id | source | docs |
+|---|---|---|
+| `stub` | `@hanzo/id-idv/providers/stub` | in-memory, dev-only |
+| `persona` | `@hanzo/id-idv/providers/persona` | https://docs.withpersona.com |
+| `onfido` | `@hanzo/id-idv/providers/onfido` | https://documentation.onfido.com |
+| `veriff` | `@hanzo/id-idv/providers/veriff` | https://developers.veriff.com |
+
+Custom providers: implement the `IDVProvider` interface in
+`pkgs/idv/src/provider.ts` and register it.
+
+## Cutover from the CF Worker
+
+1. Build + push image (PR scaffolds; image bump comes after CI green).
+2. `kubectl apply -k apps/web/k8s` — Deployment + Service + Ingress live.
+3. cert-manager issues TLS for all 4 hosts.
+4. Remove the Cloudflare Worker routes for the 4 identity hosts.
+5. Repoint CF A records: `hanzo.id`, `lux.id`, `zoo.id`, `pars.id` →
+   `129.212.164.5` (hanzo cluster ingress LB), CF-proxied.
+6. Verify each host loads its own brand.
+7. Archive `hanzo.id-worker` repo.
+
+## Backend
+
+The Go IAM backend lives at `~/work/hanzo/iam` (Casdoor fork, module
+`github.com/hanzoai/iam`, image `ghcr.io/hanzoai/iam`). All paths are under
+the `/v1/iam` prefix — no legacy `/oauth/*`, no `/api/`. This portal talks
+to it via:
+
+- auth (`pkgs/auth/src/client.ts`): `/v1/iam/login` `/v1/iam/signup`
+  `/v1/iam/send-verification-code` `/v1/iam/get-app-login`, and the OIDC
+  PKCE endpoints `/v1/iam/oauth/{authorize,token,userinfo,logout}` (via the
+  `@hanzo/iam` SDK).
+- onboarding (`pkgs/onboarding/src/service/onboarding.ts`):
+  `/v1/iam/get-organizations` (allowed for any signed-in user, scoped to
+  their memberships server-side), `/v1/iam/add-organization` +
+  `/v1/iam/add-project` (admin-gated in IAM authz — the create path surfaces
+  a permission message for non-admins and stays skippable),
+  `/v1/iam/get-account` + `/v1/iam/update-user?columns=web3onboard` (wallet
+  link).
+
+All hostnames talk to the same IAM backend — the org is carried in the
+request body (`organization: <orgId>`), and the IAM backend tenant-scopes
+on that.

-
-## Configuration
-
-Branding can be configured in two ways:
-
-### 1. Static Configuration (for known domains)
-
-Edit `lib/branding.ts` to add your domain:
-
-```typescript
-export const staticBranding: Record<string, Partial<BrandingConfig>> = {
-  'your-domain.com': {
-    orgId: 'your-org',
-    orgName: 'Your Organization',
-    logo: '/logos/your-logo.svg',
-    colors: {
-      primary: '#3b82f6',
-      primaryText: '#ffffff',
-      background: '#000000',
-      surface: '#0a0a0a',
-      text: '#ffffff',
-      textMuted: '#a1a1aa',
-      border: '#27272a',
-      error: '#dc2626',
-    },
-    content: {
-      title: 'Welcome to Your App',
-      subtitle: 'Sign in to continue',
-    },
-  },
-}
-```
-
-### 2. Dynamic Configuration (from IAM backend)
-
-The login page fetches branding from IAM API:
-
-```
-GET https://api.hanzo.id/api/branding?domain=your-domain.com
-```
-
-Response:
-```json
-{
-  "orgId": "your-org",
-  "orgName": "Your Organization",
-  "logo": "https://...",
-  "colors": { ... },
-  "content": { ... },
-  "links": { ... },
-  "auth": { ... }
-}
-```
-
-## Development
+## Local dev
 
 ```bash
-# Install dependencies
-npm install
-
-# Start development server
-npm run dev
-
-# Build for production
-npm run build
-
-# Start production server
-npm start
+pnpm install
+pnpm dev                 # http://localhost:5173 (defaults to hanzo brand)
 ```
 
-## Environment Variables
+To preview a different brand locally, edit `/etc/hosts`:
+
+```
+127.0.0.1  lux.id zoo.id pars.id
+```
+
+then visit `http://lux.id:5173`.
+
+## Build
 
 ```bash
-# IAM backend URL
-HANZO_IAM_URL=https://api.hanzo.id
-
-# Public IAM URL (for client-side redirects)
-NEXT_PUBLIC_IAM_URL=https://api.hanzo.id
+pnpm build               # builds apps/web -> dist/
+docker build -t ghcr.io/hanzoai/id:0.1.0 .
 ```
 
-## Forking for White-Label
+## Adding a brand
 
-1. Fork this repository
-2. Update `lib/branding.ts` with your default branding
-3. Add your logo to `public/logos/`
-4. Update `app/globals.css` for custom styling
-5. Deploy to your infrastructure
+1. Publish or workspace-link the new per-org brand pkg (must ship
+   `brand.json` at the package root and match the `BrandContract` shape
+   in `pkgs/shared/src/types.ts`).
+2. Add a `DEFAULT_TENANTS` entry in `pkgs/shared/src/tenant.ts` OR put
+   the override in the runtime catalog (`IAM_TENANT_CONFIG_JSON` env)
+   so no rebuild is needed.
+3. Add the hostname to `apps/web/vite.config.ts::BRAND_PACKAGES`
+   (lets dev + build serve `/brand/<pkg>/brand.json`).
+4. Add the hostname + TLS secret to `apps/web/k8s/ingress.yaml`.
+5. DNS: CNAME or A record → cluster ingress IP.
 
-## Directory Structure
+That's it — no per-brand Worker, no per-brand image, no per-brand
+deployment. One binary, four brands.

+ * (hanzoai/static) cannot map to the on-disk file — it falls through to the
+ * SPA catch-all and returns index.html, so the runtime brand fetch would parse

+# @luxwallet/connect
+
+Multi-chain wallet connect + **Sign-In-With-X** for **EVM, Solana, Bitcoin, TON, XRP**.
+
+One vocabulary, one canonical login message ([CAIP-122](https://github.com/ChainAgnostic/CAIPs/blob/main/CAIPs/caip-122.md)),
+one verifier. **MIT licensed — zero GPL.** This is the clean wallet stack; the
+Uniswap-derived GPL bones stay quarantined in `luxfi/exchange`.
+
+## Why
+
+`@luxfi/wallet` (Uniswap "Universe" fork) is GPL-3.0 and EVM-only. This package
+is a from-scratch, permissively-licensed connector that any Hanzo/Lux/Zoo/Pars
+surface — `hanzo.id` login, the browser extension, web and mobile apps — can use
+to authenticate a wallet on **any** supported chain.
+
+## Architecture
+
+```
+connect(chain) ─► Account ─► signLogin(challenge) ─► SignedProof ─► verifyProof()
+                  (browser, per-chain connector)      (server, one pure fn)
+```
+
+- **`caip122.ts`** — render/parse the canonical login message. `build ∘ parse` round-trips.
+- **`verify.ts`** — `verifyProof(proof, expected)`: parse → enforce domain/nonce/time → dispatch to the per-chain crypto verifier. Pure, fails closed, never throws.
+- **`<chain>/`** — per-chain connector (browser) + verifier (pure crypto).
+- **`go/walletconnect`** — Go port of `verifyProof`, imported by Hanzo IAM so the server verifies identically.
+
+## Chain support
+
+| Chain | Connect lib (license) | Login proof | Connector | Verifier |
+|-------|-----------------------|-------------|-----------|----------|
+| EVM | `viem` (MIT) — EIP-6963 / `window.ethereum` | EIP-191 `personal_sign` | ✅ `evm/connect.ts` | ✅ secp256k1 recover |
+| Solana | injected provider (Phantom/Solflare/Backpack) | ed25519 `signMessage` | ✅ `solana/connect.ts` | ✅ ed25519 |
+| Bitcoin | `sats-connect` (MIT) — Xverse/Leather/Unisat | BIP-322 | ✅ `bitcoin/connect.ts` | ✅ legacy + BIP-322 |
+| TON | `@tonconnect/sdk` (Apache-2.0) | `ton_proof` | ✅ `ton/connect.ts` | ✅ ed25519 envelope |
+| XRP | `@crossmarkio/sdk` (MIT) — Crossmark | `signInAndWait` | ✅ `xrp/connect.ts` | ✅ secp256k1 + ed25519 |
+
+All connect libs are MIT/Apache/ISC — **no GPL anywhere** in the dependency tree.
+GemWallet is intentionally not wired: its only client, `@gemwallet/api`, ships
+under a custom dual license requiring GemWallet's permission for public/commercial
+use — incompatible with the MIT/Apache/ISC-only rule. Crossmark covers both XRPL
+key types, so the XRP path is complete without it.
+
+### Architecture: server verify never pulls a wallet lib
+
+The wallet libraries are **optional peer dependencies**. The server-side
+`verifyProof` path imports only `@noble/*` + `bs58`:
+
+```ts
+import { verifyProof } from '@luxwallet/connect/verify';     // zero wallet libs
+import { buildSiwxMessage } from '@luxwallet/connect/caip122'; // zero deps
+```
+
+Connectors live behind separate entrypoints, so a server bundle stays clean:
+
+```ts
+import { loginWithWallet, getConnector } from '@luxwallet/connect/connectors';
+import { EvmConnector } from '@luxwallet/connect/evm/connect';
+```
+
+## Use
+
+```ts
+// Server: mint a challenge
+import { newChallenge, verifyProof } from '@luxwallet/connect';
+const challenge = newChallenge({ domain: 'hanzo.id', uri: 'https://hanzo.id/login' });
+// → store challenge.nonce, send challenge to the client
+
+// Server: verify what comes back
+const res = verifyProof(proof, { domain: 'hanzo.id', nonce: challenge.nonce });
+if (res.ok) { /* res.address is authenticated on res.chain */ }
+```
+
+```ts
+// Client (browser): connect a wallet and sign the challenge in one call.
+import { loginWithWallet } from '@luxwallet/connect/connectors';
+
+const { account, proof } = await loginWithWallet({ chain: 'evm', challenge });
+// → POST `proof` to the server, which calls verifyProof(proof, { domain, nonce }).
+
+// Or drive a connector directly:

+ * Coverage:
+ *   • Legacy "Bitcoin Signed Message" (recoverable ECDSA) over a real CAIP-122
+ *     login message — for P2PKH, P2WPKH and P2TR (BIP-86) addresses.
+ *   • BIP-322 "simple" for P2WPKH (ECDSA / BIP-143) and P2TR key-path
+ *     (Schnorr / BIP-341).
+ *   • Tamper / wrong-address / wrong-type negatives (fail closed).
+ *   • Anchors: the BIP-322 message hash + to_spend txid + P2WPKH derivation
+ *     are pinned to the official Bitcoin Core BIP-322 test vectors, so the
+ *     sighash construction is verified against a known-answer source rather
+ *     than only self-consistently.
