release: browser-extension 1.9.26 — working login (hanzo-browser IAM client)

1.9.25 shipped the unregistered app-hanzo client_id, so the PKCE token
exchange failed invalid_client — login has been dead since v1.8.0. The
canonical registered client is hanzo-browser (universe IAM init_data;
redirectUris include https://hanzo.ai/callback). Contracts pinning the
registered client land in shared-config + cross-browser-parity tests.

-# LLM.md - Hanzo Extension
+# Hanzo Extension
 
-## Overview
-Hanzo AI Development Platform Monorepo
+Browser extension (`packages/browser`) that joins the shared local **zapd** fabric.
+One native primitive — no WebSocket, no localhost port, no mDNS, no CDP bridge.
+Ships Chrome / Firefox / Safari. Build: esbuild (`src/build.js`, `pnpm build`);
+tests: vitest.
 
-## Tech Stack
-- **Language**: TypeScript/JavaScript
+## Architecture (native ZAP)
 
-## Build & Run
-```bash
-pnpm install && pnpm build
-pnpm test
-```
+    extension ─connectNative("ai.hanzo.zap")─► native host ─UDS─► zapd ◄─ hanzo-mcp

+- `shared/native-zap.ts` — the ONE transport: `connectNativeZap()` opens the native
+  port (**singleton** — one port; the router does evict-and-replace), registers as
+  provider `browser:<engine>/<host>/default`, dispatches inbound ROUTE commands.
+  Cross-browser (`browser ∥ chrome`).
+- `background.ts` (Chrome) — dispatch via `chrome.debugger` (CDP→tab; shows the
+  "debugging this browser" banner; WebKit-incompatible). **To be removed** — see WXT plan.
+- `background-firefox.ts` — native `browser.*` dispatch (no banner). The correct model.
+- `browser-dispatch.ts` — `chrome.debugger` actuation (Chrome-only).
+- `shared/evaluable.ts` — the ONE evaluate rule: `pickEvaluable` (code-param
+  aliases) + `wrapEvaluable` (bare expression passes through; statement bodies
+  → async IIFE with the trailing value auto-returned). Both dispatch paths
+  consume it, so Chrome and Firefox accept identical caller JS.
 
-## Key Files
-- `README.md` -- Project documentation
-- `package.json` -- Dependencies and scripts
-- `Makefile` -- Build automation
+Wire to zapd: the binary ZAP router envelope (`zap-proto/zapd/src/frame.rs`); the
+browser↔host hop is native-messaging JSON, base64'd, quarantined in the host. Host +
+per-browser manifests come from `zapd install-host` (`zap-proto/zapd`).
+
+## Versioning
+Patch only (X.Y.Z+1), never major. `package.json` is the source of truth; `build.js`
+stamps it into every manifest (chrome/firefox/safari).
+
+## Cross-platform — WXT migration (canonical plan, not yet executed)
+
+One WebExtension codebase, every engine. **WXT** = build/SDK layer (build matrix,
+manifest gen, targets, MV3, Vite/TS); `webextension-polyfill` / `@wxt-dev/browser` =
+`browser.*` normalization. **Custom (keep):** `shared/native-zap.ts`, and the Safari
+`SafariWebExtensionHandler.swift` → `~/.zap/run/zapd.sock` bridge. WXT builds Safari
+but does NOT give WebKit `chrome.debugger` — so dispatch must become portable
+`browser.*` (the Firefox model is already correct).
+
+1. Adopt WXT build matrix (chrome/firefox/safari) — replaces `build.js`.
+2. Collapse forks → one `background.ts`; delete `background-firefox.ts`; runtime
+   `browser` adapter.
+3. Collapse dispatch → delete `chrome.debugger` / `browser-dispatch.ts`; actuate over
+   `tabs`/`scripting`/`webNavigation`/`browser.*` (portable, no banner, Safari-capable).
+4. Transport stays per-platform: Chrome/Firefox `connectNative` → host → `zapd.sock`;
+   Safari `SafariWebExtensionHandler.swift` → `zapd.sock`.
+5. CI guards (last; go red until 1–4 land): fail if `chrome.debugger`, the `debugger`
+   permission, or `background-firefox.ts` appears.
+
+Large, multi-phase — do it as a focused pass, never half-merged.

-
-## Backend Abstraction
-
-### Local vs Cloud Support
-
-✅ **Local Backend**
-- In-memory graph database
-- Local vector store with mock embeddings
-- File-based document persistence
-- Support for Ollama and LM Studio
-- Hanzo local model support
-
-✅ **Cloud Backend**
-- API-based operations
-- Real embeddings from cloud
-- Persistent storage
-- Authentication via API key
-- Unified interface with local
-
-### AI Model Support
-
-✅ **Local AI Providers**
-- Ollama (auto-detected at localhost:11434)
-- LM Studio (auto-detected at localhost:1234)
-- Hanzo Local Models (zen1, zen1-mini, zen1-code)
-
-✅ **Cloud AI Providers**
-- Hanzo Cloud API
-- Fallback to OpenAI/Anthropic
-- Unified LLM interface
-
-## Critic Tool Capabilities
-
-The critic tool provides comprehensive code analysis:
-
-1. **Security Analysis**
-   - SQL injection detection
-   - XSS vulnerability checks
-   - Authentication/authorization issues
-   - Sensitive data exposure
-
-2. **Performance Analysis**
-   - Algorithm complexity
-   - Database query optimization
-   - Memory leak detection
-   - Unnecessary computations
-
-3. **Code Quality**
-   - Naming conventions
-   - Code organization
-   - Documentation coverage
-   - Error handling
-
-4. **Correctness**
-   - Logic errors
-   - Edge case handling
-   - Type safety
-   - Test coverage
-
-## Missing/Partial Implementations
-
-### Tools Not Yet Implemented
-- ❌ AST analyzer (compilation issues with TypeScript parser)
-- ❌ Tree-sitter analyzer (module resolution issues)
-- ❌ Jupyter notebook tools (notebook_read, notebook_edit)
-- ❌ SQL database tools (sql_query, sql_search)
-- ❌ LLM consensus tool
-- ❌ Agent dispatch tool
-- ❌ Some system tools (memory, date, copy, move, delete)
-
-### Limitations
-- Vector store uses mock embeddings (real embeddings need API integration)
-- Graph database is in-memory only for local mode
-- Document store requires file system access
-
-## Recommendations
-
-1. **Enable More Tools by Default**
-   - Consider enabling graph_db, vector tools, and zen by default
-   - These are now fully tested and performant
-
-2. **Real Embeddings**
-   - Integrate with OpenAI/Cohere for real embeddings
-   - Or use local sentence-transformers
-
-3. **Persistent Storage**
-   - Add SQLite backend option for local persistence
-   - Implement proper backup/restore
-
-4. **Complete AST Integration**
-   - Fix TypeScript compilation issues
-   - Add tree-sitter support for more languages
-
-## Summary
-
-✅ **27 tools** fully implemented and tested
-✅ **Excellent performance** across all subsystems
-✅ **Local and cloud** backend abstraction working
-✅ **AI model integration** for Ollama, LM Studio, and Hanzo
-✅ **Comprehensive testing** with benchmarks
-
-The extension is production-ready with all core functionality working as expected.

+ * `@hanzo/gui` package because:
+ *
+ *   1. content-script + background bundles target the smallest possible

+ *      primaryColor #FFFFFF), so no color tokens travel with primitives
+ *      anyway — pure structural elements styled by sibling CSS;
+ *   3. The full tamagui adoption ships in a future feature branch with the
+ *      compiler + RNW peer dep wired correctly.
+ *
+ * The build aliases `@hanzo/gui` → this file. When the tamagui adoption
+ * lands, swap the alias target to the published `@hanzo/gui` package.
+ *

+//     GPUBuffer and consumed by the inline matmul/softmax shaders below.
+//   - GGUF (llama.cpp's quantized container, v1-v3): parsed into a
+//     name-keyed map of (offset, length, dtype, shape) descriptors, with
+//     each tensor lazily uploaded to its own GPUBuffer through ExpertCache.
+//     This unlocks Zen-Nano/Zen-Eco/Zen-Coder GGUF artifacts published on

+// Sparse-load shell (ExpertCache below) materialises tensors on demand and

+// holds every layer; for MoE (Zen Coder 480B, etc.) it only ever holds the
+// experts the router actually picks for live tokens, which is the whole

+//     tokens, large MoE verify (Zen Coder 31B/3B-active) checking the batch
+//     in one forward pass. Layered on top of the kernels.
