* fix: remove gnubok_categorize_with_receipt tool
The tool requires Claude to generate the entire base64-encoded file as
tool arguments token-by-token, which is extremely slow for large PDFs.
Receipt attachment should happen via the widget (where JavaScript
handles encoding) or through the web app.
The receipt matcher widget and gnubok_receipt_matcher tool remain —
they provide the intended UX for matching receipts to transactions.

* fix: update widget to call gnubok_categorize_transaction
The widget was still calling the removed gnubok_categorize_with_receipt
tool. Updated to call gnubok_categorize_transaction instead (text-only,
no file upload). Receipt attachment via the widget is deferred to a
future iteration.

* feat: add MCP Apps receipt matcher widget for inline receipt-to-transaction matching
Adds an interactive HTML widget that renders inline in Claude Desktop via MCP Apps
(SEP-1865), letting users drag receipts onto uncategorized transactions to categorize,
book, and attach documents in one flow without leaving the conversation.
- Extract categorizeTransactionCore() shared by both categorization tools
- Add gnubok_receipt_matcher tool with _meta.ui for MCP Apps widget rendering
- Add gnubok_categorize_with_receipt tool (categorize + upload document)
- Add resources/list and resources/read protocol handlers
- Self-contained widget HTML with MCP Apps bridge, drag-and-drop, client-side resize

* fix: address review feedback — buffer slice, MIME type, HTML escaping
- Fix Buffer.buffer slab pool issue: slice to exact byte range to avoid
corrupted uploads for small files (≤4096 bytes)
- Update MIME type to image/jpeg after canvas re-encode (was keeping
original file.type, causing content-type mismatch in DB)
- Escape tx.date through esc() for consistent innerHTML sanitization
- Remove unused `reset` variable in tests

* fix: return 202 for MCP notifications and echo client protocol version
- notifications/initialized returns 202 Accepted per MCP Streamable
HTTP spec (was 204 which may prevent tool discovery)
- Echo client's protocolVersion in initialize response
- Add instructions field for server description

* fix: validate protocol version and handle notifications pre-auth
- Validate protocolVersion against supported set instead of blindly
echoing (prevents false protocol agreement with unknown versions)
- Handle notifications/initialized before auth check so fire-and-forget
notifications don't get 401 responses that confuse MCP clients

* fix: return plain 401 for MCP OAuth discovery and harden auth flow
- Return plain HTTP 401 with WWW-Authenticate header (no JSON-RPC body)
so Claude Desktop's MCP client can trigger OAuth discovery correctly
- Remove unused apiKey import from authorize route
- Remove stale codeChallengeMethod parameter from oauth-codes

* fix: prevent Chrome auto-translate from crashing React during onboarding
Chrome auto-translate modifies DOM text nodes when it detects a Swedish
page (lang="sv") in a browser set to English. React does not expect
external DOM mutations and throws, crashing the entire component tree
into global-error.tsx on every step transition.
Add translate="no" and <meta name="google" content="notranslate"> to
suppress browser translation. Also fix timezone-unsafe date parsing in
fiscal period validation (new Date("YYYY-MM-DD") + getDate() returns
local-timezone values, shifting dates by -1 day in Western timezones).

* fix: add notranslate meta tag to global-error.tsx for consistency
Per review feedback — global-error.tsx renders its own <html> document,
so it needs the same <meta name="google" content="notranslate"> tag as
layout.tsx to fully suppress Chrome translation on error pages.

* feat: add MCP server extension with OAuth, API keys, and KPI dashboard
Let users do bookkeeping through Claude Desktop, Claude Code, or any
MCP-compatible client. "Show my uncategorized transactions." "Book that
as office supplies." "Invoice Acme for 15,000 kr."
MCP server (extension):
- 10 tools: transactions, categorization, customers, invoices,
trial balance, VAT report, KPI report, income statement
- JSON-RPC 2.0 protocol (no SDK dependency, works in serverless)
- Tool annotations, pagination, input validation per MCP best practices
- Same engine as web UI (VAT rules, exchange rates, event emission)
API key infrastructure (core):
- api_keys table with RLS, rate limiting (100 RPM), scopes column
- Atomic rate limit via DB RPC (validate_and_increment_api_key)
- Key management API routes + settings UI panel
OAuth 2.1 for Claude Desktop connectors:
- .well-known/oauth-protected-resource + oauth-authorization-server
- Authorization endpoint with consent page
- Token endpoint with PKCE verification
- Stateless encrypted auth codes (AES-256-GCM, no DB storage)
- Dynamic client registration
KPI dashboard:
- /nyckeltal page with hero cards, operational grid, trend chart
- GET /api/reports/kpi endpoint
- Gross margin, cash position, expense ratio, avg payment days,
VAT liability, revenue/expense trend

* fix: address OAuth security vulnerabilities from code review
Critical fixes:
- Auth code replay: Track used codes in oauth_used_codes table with
unique constraint. Codes are single-use per OAuth 2.1 §4.1.2.
- Open redirect: Validate redirect_uri against hardcoded allowlist
of known Claude callback URLs + localhost for dev.
P1 fixes:
- Move API key creation from /authorize to /token endpoint. Keys are
only created after PKCE verification, preventing orphaned keys on
abandoned OAuth flows.
- Add ensureInitialized() to MCP server so event handlers load and
transaction.categorized events reach extensions.
P2 fixes:
- Remove 'plain' from PKCE methods — only S256 is advertised and
accepted.
- Fix extension count in sectors test (10 → 11 for mcp-server).

* fix: remove duplicate ensureInitialized() that caused circular import
The extension router (ext/[...path]/route.ts) already calls
ensureInitialized() before dispatching to handlers. The duplicate
call in server.ts created a circular import that Turbopack couldn't
resolve, breaking the Vercel build.
