+## Google Gemini (OAuth)
+
+Uses Google OAuth with PKCE (S256) for authentication — no API key required.
+On first run, a browser opens for Google account login. Credentials (including
+refresh token) are saved to `~/.gemini/oauth_creds.json` with `0600` permissions.
+
+```env
+LLM_BACKEND=gemini_oauth
+GEMINI_MODEL=gemini-2.5-flash
+```
+
+### Supported features
+
+| Feature | Status | Notes |
+|---|---|---|
+| Function calling | ✅ | `functionDeclarations` / `functionCall` / `functionResponse` |
+| `generationConfig` | ✅ | `temperature`, `maxOutputTokens` passed from request |
+| `thinkingConfig` | ✅ | `thinkingBudget`/`thinkingLevel` for thinking-capable models (does NOT set `includeThoughts`) |
+| `toolConfig` | ✅ | `functionCallingConfig.mode`: `AUTO`/`ANY`/`NONE` |

+
+### Cloud Code API vs standard API
+
+Models containing `-preview` (with hyphen) or `gemini-3` in the name, as well
+as any `gemini-` model with major version >= 2, route through the Cloud Code
+API (`cloudcode-pa.googleapis.com`) which supports SSE streaming
+and project-scoped access. Other models use the standard Generative Language
+API (`generativelanguage.googleapis.com`).
+
+---
+
+## GitHub Copilot
+
+GitHub Copilot exposes chat endpoint at
+`https://api.githubcopilot.com`. IronClaw uses that endpoint directly through the
+built-in `github_copilot` provider.
+
+```env
+LLM_BACKEND=github_copilot
+GITHUB_COPILOT_TOKEN=gho_...
+GITHUB_COPILOT_MODEL=gpt-4o
+# Optional advanced headers if your setup needs them:
+# GITHUB_COPILOT_EXTRA_HEADERS=Copilot-Integration-Id:vscode-chat
+```
+
+`ironclaw onboard` can acquire this token for you using GitHub device login. If you
+already signed into Copilot through VS Code or a JetBrains IDE, you can also reuse
+the `oauth_token` stored in `~/.config/github-copilot/apps.json`. If you prefer,
+`LLM_BACKEND=github-copilot` also works as an alias.
+
+Popular models vary by subscription, but `gpt-4o` is a safe default. IronClaw keeps
+model entry manual for this provider because GitHub Copilot model listing may require
+extra integration headers on some clients. IronClaw automatically injects the standard
+VS Code identity headers (`User-Agent`, `Editor-Version`, `Editor-Plugin-Version`,
+`Copilot-Integration-Id`) and lets you override them with
+`GITHUB_COPILOT_EXTRA_HEADERS`.
+

+## GitHub Copilot Provider Notes
+
+`github_copilot` uses a dedicated `GithubCopilotProvider` (`github_copilot.rs`) with
+direct HTTP via `reqwest::Client`. It cannot use `RigAdapter` because the Copilot API
+requires a two-step authentication flow: a long-lived GitHub OAuth token is exchanged
+for a short-lived Copilot session token via `api.github.com/copilot_internal/v2/token`.
+The session token is cached and auto-refreshed before expiry by `CopilotTokenManager`
+in `github_copilot_auth.rs`.
+
+The API endpoint is `https://api.githubcopilot.com/chat/completions` (OpenAI Chat
+Completions format). Token source: `GITHUB_COPILOT_TOKEN` env var, or the
+`oauth_token` from your IDE sign-in flow (`~/.config/github-copilot/apps.json`).
+The setup wizard supports GitHub device login or manual token paste.
+
+**Known risk:** The device login flow uses the VS Code Copilot OAuth client ID
+(`Iv1.b507a08c87ecfe98`) and injects VS Code identity headers (`User-Agent`,
+`Editor-Version`, `Editor-Plugin-Version`, `Copilot-Integration-Id`). GitHub could
+rotate this client ID at any time. If GitHub publishes an official third-party client
+ID, migrate to it immediately. Advanced users can override headers via
+`GITHUB_COPILOT_EXTRA_HEADERS`.

+//! GitHub Copilot provider (direct HTTP with token exchange).
+//!
+//! The GitHub Copilot API at `api.githubcopilot.com` speaks OpenAI Chat
+//! Completions format but requires a two-step authentication flow:
+//! 1. A long-lived GitHub OAuth token (from device login or IDE sign-in)
+//! 2. A short-lived Copilot session token (exchanged via GitHub API)
+//!
+//! The standard OpenAI rig-core client sends `Authorization: Bearer <token>`
+//! with the raw OAuth token, which gets rejected with "Authorization header
+//! is badly formatted". This provider handles the token exchange transparently.

+// ─── Risk: hardcoded VS Code Copilot identity ───────────────────────────────
+//
+// The client ID and editor identity headers below are extracted from the
+// VS Code Copilot Chat extension.  This is the *only* publicly documented
+// way to access the Copilot completions API with a personal GitHub token.
+//
+// **Known risks:**
+//   • GitHub may rotate or revoke this client ID at any time, which would
+//     break authentication for all IronClaw users until the constant is
+//     updated and a new release is shipped.
+//   • Using another product's client ID may violate GitHub's Terms of
+//     Service.  Maintainers should seek explicit guidance from GitHub
+//     before shipping this to a wide audience.
+//   • The editor version strings (`vscode/1.99.3`, `copilot-chat/0.26.7`)
+//     will become stale and could eventually be rejected by the API.
+//
+// **Mitigation:** If GitHub publishes an official Copilot API client ID or
+// an OAuth app registration flow for third-party tools, migrate to it
+// immediately.
+// ─────────────────────────────────────────────────────────────────────────────

+## Multi-Scope Reads & Identity Isolation
+
+When a workspace has additional read scopes (via `with_additional_read_scopes`), read operations can span multiple user scopes — a user with scopes `["alice", "shared"]` can read documents from both.
+
+**Identity files are exempt from multi-scope reads.** The system prompt reads identity and configuration files from the **primary scope only** (`read_primary()`), never from secondary scopes:
+
+| File | Read method | Rationale |
+|------|------------|-----------|
+| AGENTS.md | `read_primary()` | Agent instructions are per-user |
+| SOUL.md | `read_primary()` | Core values are per-user |
+| USER.md | `read_primary()` | User context is per-user |
+| IDENTITY.md | `read_primary()` | Identity is per-user |
+| TOOLS.md | `read_primary()` | Tool config is per-user |
+| BOOTSTRAP.md | `read_primary()` | Onboarding is per-user |
+| MEMORY.md | `read()` | Shared memory is a feature |
+| daily/*.md | `read()` | Shared daily logs are a feature |
+
+**Why:** Without this, a user with read access to another scope could silently inherit that scope's identity if their own copy is missing. The agent would present itself as the wrong user — a correctness and security issue.
+
+**Design rule:** If you want shared identity across users, seed the same content into each user's scope at setup time. Don't rely on multi-scope fallback for identity files.

+- All standard OAuth parameters are present and correctly encoded
+- URLs are consistent across channels (web, Telegram, etc.)

+//! constructs the correct HTTP API call via `http_exchanges` in the trace.
+//!
+//! These tests are `#[ignore]` by default because they require a pre-compiled
+//! WASM binary. Build it with:

+//! Tests for identity file scope isolation in multi-scope workspaces.
+//!
+//! When a workspace has multiple read scopes (e.g., Andrew can read from
+//! "andrew", "grace", "household"), identity files (SOUL.md, USER.md,
+//! IDENTITY.md, AGENTS.md) must ONLY come from the primary scope.
+//!
+//! Multi-scope reads are designed for memory sharing (MEMORY.md, daily logs),
+//! not identity inheritance. Silently inheriting identity from another scope
+//! is a correctness and security issue — the agent would present itself as
+//! the wrong user.
+//!
+//! These tests verify that:
+//! 1. Identity files are read from primary scope only
+//! 2. If the primary scope's identity file is missing, it's absent from the
+//!    system prompt — never falls back to another scope
+//! 3. Memory files (MEMORY.md) still benefit from multi-scope reads

+//! Integration tests for multi-tenant auth, isolation, and per-user scoping.
+//!
+//! These tests verify that multi-tenant infrastructure works correctly:
+//! - Token-to-identity mapping via MultiAuthState
+//! - Per-user SSE event scoping (user A doesn't see user B's events)
+//! - Per-user rate limiting (user A exhausting limit doesn't block user B)
+//! - Auth middleware inserts correct UserIdentity into request extensions
+//! - WebSocket connections are scoped to the authenticated user

+//! Regression tests for multi-tenant system prompts.
+//!
+//! The agent must build the conversational system prompt from a workspace
+//! scoped to the incoming message's user, not from the shared owner-scope
+//! workspace created at startup. Otherwise per-user identity files
+//! (IDENTITY.md, SOUL.md, USER.md) become invisible and different users can
+//! see the same owner-scoped prompt.
+//!
+//! These tests:
+//! 1. Seed identity files for two users (alice, bob) in the database
+//! 2. Send messages as each user
+//! 3. Verify the system prompt in captured LLM requests contains the
+//!    correct user's identity
+//! 4. Verify user A's identity doesn't leak into user B's prompt
+//!
+//! These tests ensure each user's identity is isolated correctly.

+//! Regression and unit tests for shell command risk-level classification
+//! (issue #172, PR #368).
+//!
+//! These tests live here (instead of inline in `src/tools/builtin/shell.rs`)
+//! because the project's no-panics CI check scans `src/**/*.rs` for
+//! `assert_eq!` / `assert_ne!` / `.unwrap()` in added lines.  All assertions
+//! on the public `ShellTool` API belong here.
+//!
+//! All tests access the shell tool through the public `ToolRegistry` +
+//! `Tool` trait surface (`risk_level_for`, `requires_approval`).
+//!
+//! ## What is tested
+//!
+//! 1. **Risk level tiers** (`High`, `Medium`, `Low`) for representative commands.
+//! 2. **Word-boundary matching** — commands whose names are substrings of other
+//!    words must not be misclassified.
+//! 3. **Pipeline aggregation** — the whole pipeline takes the maximum risk of
+//!    its segments.
+//! 4. **Redirect bypass regression** — Low-risk commands with shell redirections
+//!    must return `UnlessAutoApproved`, not `Never`.
+//! 5. **`git push` regression** — non-force push is explicitly `Medium`; force
+//!    variants remain `High`.
+//! 6. **`risk_level_for` trait method** — delegates to classify_command_risk.
