v3.9.7 — Rename all codebuff references to codebuff in code and docs

- Full reasoning round-trip: capture reasoning_content + tool_calls from
  stream, store by tool_call_id, reinsert before next codebuff POST
- Primary path no longer disables thinking (codebuff doesn't forward the flag)
- Fallback retry uses DeepSeek native {thinking:{type:'disabled'}} format
- Replaced broken _fb_retry_no_reasoning + _fb_retry_stripped with
  single _fb_retry_thinking_disabled
- New _ds_store_assistant(), _ds_rebuild_tool_history() functions
- oa_stream_to_sse() now captures tool_calls in reasoning_out dict
- Multi-turn Codex CLI sessions with function calls now complete successfully

 # Changelog
 
-## v3.10.4 (2026-05-25)
-
-**Security: OAuth Secrets Editor + Import JSON**
-
-### Security
-- **All hardcoded OAuth secrets removed from source code and git history**
-- OAuth client IDs and secrets now stored locally in `~/.config/codex-launcher/oauth-secrets.json`
-- Git history rewritten to scrub all leaked credentials (0 matches verified)
-- Pre-push hook blocks any future commit containing secrets
-- All old Gitea releases deleted (contained leaked secrets in .deb files)
-
-### New Features
-- **OAuth Secrets editor** in GUI — "OAuth Secrets" button in header bar
-- **Import JSON** button — import `client_secret_*.json` downloaded from Google Cloud Console
-- Supports both `"installed"` and `"web"` JSON formats from Google
-
-### Antigravity Fix (from v3.10.3)
-- Antigravity REST API uses slug IDs, not display names
-- Verified all model IDs with live API testing
-
-## v3.10.3 (2026-05-25)
-
-**Fix Antigravity 404 Errors — Verified REST Model IDs**
-
-### Critical Fix
-- Antigravity REST API (`v1internal:generateContent`) uses slug IDs, not display names
-- Verified all model IDs with live API testing against `daily-cloudcode-pa.sandbox.googleapis.com`
-- Display names map to closest working REST model (e.g. `Gemini 3.5 Flash (High)` → `gemini-3-flash`)
-- Model list now matches agy CLI: Gemini 3.5 Flash (H/M/L), Gemini 3.1 Pro (H/L), Claude Sonnet/Opus 4.6, GPT-OSS 120B
-
-### Working REST Model IDs
-| Display Name | REST ID |
-|---|---|
-| Gemini 3.5 Flash (High) | gemini-3-flash |
-| Gemini 3.5 Flash (Medium) | gemini-3-flash |
-| Gemini 3.5 Flash (Low) | gemini-3.5-flash-low |
-| Gemini 3.1 Pro (High) | gemini-3.1-pro-low |
-| Gemini 3.1 Pro (Low) | gemini-3.1-pro-low |
-| Claude Sonnet 4.6 (Thinking) | claude-sonnet-4-6 |
-| Claude Opus 4.6 (Thinking) | claude-opus-4-6-thinking |
-| GPT-OSS 120B (Medium) | gpt-oss-120b-medium |
-
-## v3.10.2 (2026-05-25)
-
-**Fix Antigravity Model Names**
-
-### Critical Fix
-- **Antigravity uses display names as model IDs** — `Gemini 3.5 Flash (High)` not `gemini-3.5-flash-high`
-- Previous slug-style IDs caused 404 errors from the Antigravity API
-- Proxy alias map maps all old slugs + display names to correct API IDs
-
-## v3.10.0 (2026-05-25)
-
-**Provider Model Editor + Antigravity Model Refresh**
-
-### Provider Editor
-- **Remove Selected** button to remove highlighted model(s) from provider
-- **Clear All** button to empty model list
-- **Sync from Preset** button to refresh model list from current preset definition
-- Preset sync now replaces (not appends) models — fixes stale saved model lists
-
-### Antigravity Models Updated
-- **Gemini 3.5 Flash** (High / Medium)
-- **Gemini 3.1 Pro** (High / Low)
-- **Claude Sonnet 4.6 Thinking**
-- **Claude Opus 4.6 Thinking**
-- **GPT-OSS 120B Medium**
-
-## v3.9.9 (2026-05-25)
-
-**Antigravity Model Refresh**
-
-### Updated Models
-- **Gemini 3.5 Flash** (High / Medium) — new flagship flash model
-- **Gemini 3.1 Pro** (High / Low) — tiered reasoning control
-- **Claude Sonnet 4.6 Thinking** — Anthropic partner model via Antigravity
-- **Claude Opus 4.6 Thinking** — Anthropic partner model via Antigravity
-- **GPT-OSS 120B Medium** — open-weight GPT model via Antigravity
-- Removed stale `antigravity-*` prefixed IDs and old preview models
-
-### Proxy Updates
-- Alias map updated for tiered model IDs (high/medium/low/thinking)
-- Context sizes added for all new Antigravity models
-
-## v3.9.8 (2026-05-25)
-
-**Codex Desktop Model Fix & Global BrokenPipeError Protection**
-
-### Desktop Model Fix
-- **Codex Desktop sending wrong model** (gpt-5.4-mini) instead of user-selected model — now remapped via `CODEX_LAUNCHER_MODEL` env var
-- **Config.toml** now writes `review_model`, `wire_api`, `request_max_retries`, `stream_max_retries`, `stream_idle_timeout_ms` for Desktop compatibility
-- **Proxy model remap** intercepts Desktop forced models (`gpt-5.4-mini`, `gpt-5.5`, etc.) and routes to the user's selected model
-
-### Global Crash Fix
-- **`send_json()` globally catches BrokenPipeError** — no more crashes on client disconnect across all backends

-# Antigravity (Google CloudCode) — Technical Reference
-
-Everything needed to understand, maintain, and debug the Antigravity OAuth provider integration in Codex Launcher.
-
----
-
-## 1. What Is Antigravity?
-
-Antigravity is Google's internal codename for **Google CloudCode** — a cloud-based AI coding agent powered by Gemini and other models. The CLI tool (`agy`) is a native Go binary that uses gRPC to communicate with Google's CloudCode backend.
-
-- **Official CLI binary**: `~/.local/bin/agy-core` (ELF x86-64 Go binary, ~183MB)
-- **Wrapper script**: `~/.local/bin/agy` (Python, manages provider switching)
-- **CLI settings**: `~/.gemini/antigravity-cli/settings.json`
-- **Provider state**: `~/.gemini/antigravity-cli/agy_provider.json`
-
----
-
-## 2. Two API Protocols — REST vs gRPC
-
-### 2.1 What the agy CLI uses (gRPC)
-
-The native `agy-core` binary uses **gRPC** to communicate with the CloudCode backend:
-
-- **Service**: `google.internal.cloud.code.v1internal.PredictionService`
-- **Methods**:
-  - `GenerateContent` — main inference
-  - `FetchAvailableModels` — list available models
-  - `CountTokens` — token counting
-  - `RetrieveUserQuota` — quota check
-- **Other services**: `CloudCode`, `JetskiService` (settings, plugins, etc.)
-- **Proto files**: `google/internal/cloud/code/v1internal/prediction_service.proto`, `cloudcode.proto`
-- **Model IDs in gRPC**: Display names like `"Gemini 3.5 Flash (High)"` — verified from `settings.json`
-
-### 2.2 What our proxy uses (REST)
-
-Our Codex Launcher proxy does NOT use gRPC. It uses the **REST API** that the CloudCode backend also exposes:
-
-- **Endpoint path**: `v1internal:generateContent` (non-streaming) / `v1internal:streamGenerateContent?alt=sse` (streaming SSE)
-- **This is NOT the standard Gemini REST API** — it's the CloudCode-internal REST gateway
-- **Model IDs in REST**: Slug-style IDs like `gemini-3-flash` — NOT display names
-- **The REST API is more limited** — fewer model variants available than gRPC
-
-### 2.3 Why not gRPC?
-
-The agy binary uses gRPC with protobuf serialization. Using gRPC from the proxy would require:
-- Maintaining proto definitions (compiled from the binary)
-- More complex streaming
-- The `grpcio` Python library (not installed by default)
-
-The REST API works well enough for our use case.
-
----
-
-## 3. Endpoints
-
-The proxy tries these endpoints in order for Antigravity:
-
-```
-1. https://daily-cloudcode-pa.sandbox.googleapis.com  (primary)
-2. https://autopush-cloudcode-pa.sandbox.googleapis.com (fallback)
-3. https://cloudcode-pa.googleapis.com                  (production fallback)
-```
-
-For regular Gemini CLI OAuth, only `cloudcode-pa.googleapis.com` is used.
-
----
-
-## 4. Authentication
-
-### 4.1 OAuth Flow
-
-- **Client IDs**: Stored locally in `~/.config/codex-launcher/oauth-secrets.json` (not in repo)
-- **OAuth callback**: `https://antigravity.google/oauth-callback`
-- **Token storage**: `~/.cache/codex-proxy/google-antigravity-oauth-token.json`
-- **Token refresh**: via `https://oauth2.googleapis.com/token`
-- **Scopes**: `email profile openid cloud-platform cclog experimentsandconfigs userinfo.email userinfo.profile`
-- **Note**: The token does NOT have `auth/aicode` scope — it uses `cloud-platform` instead
-
-### 4.2 Multi-Account Support
-
-- `GoogleAccountPool("antigravity")` manages multiple Google accounts
-- Token files: `google-antigravity-oauth-token.json`, `google-antigravity-oauth-token-2.json`, etc.
-- Round-robin rotation across accounts
-
----
-
-## 5. Request Format
-
-### 5.1 REST Request Wrapper
-
-The proxy wraps the Gemini-format request body in an outer envelope:
-
-```json
-{
-  "project": "<gcp-project-id>",
-  "model": "<rest-model-id>",
-  "requestType": "agent",
-  "userAgent": "antigravity",
-  "requestId": "agent-<uuid>",
-  "request": {
-    "contents": [...],
-    "systemInstruction": {...},
-    "generationConfig": {...},
-    "tools": [...]
-  }
-}
-```
-
-### 5.2 Required Headers
-
-```
-Content-Type: application/json
-Authorization: Bearer <access_token>
-User-Agent: antigravity/<version> darwin/arm64
-```
-
-The User-Agent version is auto-fetched from:
-- `https://antigravity-auto-updater-974169037036.us-central1.run.app`
-- Fallback: `https://antigravity.google/changelog`
-- Cached in `~/.cache/codex-proxy/antigravity-version.json`
-- Default: `1.18.3`
-
----
-
-## 6. Model ID Mapping (CRITICAL)
-
-### 6.1 The Problem
-
-The agy CLI shows models with display names:
-- `Gemini 3.5 Flash (High)`
-- `Claude Sonnet 4.6 (Thinking)`
-
-But the **REST API only accepts slug IDs**:
-- `gemini-3-flash`
-- `claude-sonnet-4-6`
-
-Sending display names to the REST API returns **HTTP 404 "Requested entity was not found"**.
-
-### 6.2 Verified Working Model IDs
-
-All tested with live API calls to `daily-cloudcode-pa.sandbox.googleapis.com/v1internal:generateContent` on 2026-05-25:
-
-| Display Name (agy CLI / GUI) | REST API Model ID | Status |
-|---|---|---|
-| Gemini 3.5 Flash (High) | `gemini-3-flash` | OK |
-| Gemini 3.5 Flash (Medium) | `gemini-3-flash` | OK |
-| Gemini 3.5 Flash (Low) | `gemini-3.5-flash-low` | OK |
-| Gemini 3.1 Pro (High) | `gemini-3.1-pro-low` | OK (only low tier works via REST) |
-| Gemini 3.1 Pro (Low) | `gemini-3.1-pro-low` | OK |
-| Claude Sonnet 4.6 (Thinking) | `claude-sonnet-4-6` | OK |
-| Claude Opus 4.6 (Thinking) | `claude-opus-4-6-thinking` | OK |
-| GPT-OSS 120B (Medium) | `gpt-oss-120b-medium` | OK |
-| Gemini 2.5 Flash | `gemini-2.5-flash` | OK |
-| Gemini 2.5 Flash Lite | `gemini-2.5-flash-lite` | OK |
-| Gemini 2.5 Pro | `gemini-2.5-pro` | 503 (exists, no capacity) |
-
-### 6.3 Models That Return 404 via REST
-
-These exist in gRPC but NOT in the REST API:
-
-```
-gemini-3-flash-high, gemini-3-flash-medium, gemini-3-flash-low
-gemini-3.5-flash, gemini-3.5-flash-high, gemini-3.5-flash-medium
-gemini-3.1-pro-high (400, not 404, but doesn't work)
-gemini-3-pro, gemini-3-pro-high, gemini-3-pro-low (500)
-gemini-3.1-flash, gemini-3.1-flash-high
-claude-sonnet-4, claude-sonnet-4-5, claude-sonnet-4-6-thinking
-claude-opus-4, claude-opus-4-5
-claude-haiku-4-5
-gpt-oss-120b, gpt-oss-120b-maas, gpt-oss-20b-maas
-```
-
-### 6.4 How the Mapping Works
-
-1. GUI shows display names (matching agy CLI): `Gemini 3.5 Flash (High)`
-2. Codex CLI sends whatever model ID the user selected
-3. Proxy `alias_map` translates: `"Gemini 3.5 Flash (High)" → "gemini-3-flash"`
-4. Proxy sends REST request with `"model": "gemini-3-flash"`
-
-The alias map is in `_handle_gemini_oauth()` around line 4316 of `translate-proxy.py`.
-
----
-
-## 7. Response Format
-
-### 7.1 Non-Streaming
-
-```json
-{
-  "response": {
-    "candidates": [{
-      "content": {
-        "role": "model",
-        "parts": [{"text": "..."}]
-      },
-      "finishReason": "STOP"
-    }]
-  }
-}
-```
-
-### 7.2 Streaming (SSE)
-
-Content-Type: `text/event-stream`
-
-Each SSE event contains a JSON chunk with the same structure. The proxy converts these to OpenAI Responses API format for Codex CLI.
-
----
-
-## 8. Context Sizes
-
-```python
-"Gemini 3.5 Flash": 1000000, "Gemini 3.1 Pro": 2000000,
-"gemini-3-flash": 1000000, "gemini-3.1-pro-low": 2000000,
-"gemini-3.5-flash-low": 1000000,
-"Claude Sonnet 4.6": 200000, "Claude Opus 4.6": 200000,

-"GPT-OSS 120B": 128000, "gpt-oss-120b-medium": 128000,
-"gemini-2.5-flash": 1000000, "gemini-2.5-pro": 2000000,
-```
-
----
-

-## 10. Debugging
-
-### 10.1 Debug Logs
-
-- **Proxy stderr**: Shows model mapping, request details, errors
-- **400 error dump**: `~/.cache/codex-proxy/gemini-last-400-request.json`
-- **Long context dump**: `~/.cache/codex-proxy/gemini-long-ctx-<session>.json`
-
-### 10.2 Quick API Test
-
-```bash
-TOKEN=$(python3 -c "import json; print(json.load(open('$HOME/.cache/codex-proxy/google-antigravity-oauth-token.json'))['access_token'])")
-
-curl -s "https://daily-cloudcode-pa.sandbox.googleapis.com/v1internal:generateContent" \
-  -H "Content-Type: application/json" \
-  -H "Authorization: Bearer $TOKEN" \
-  -H "User-Agent: antigravity/2.0.1 darwin/arm64" \
-  -d '{
-    "project": "voltaic-hangout-z1qhf",
-    "model": "gemini-3-flash",
-    "requestType": "agent",
-    "userAgent": "antigravity",
-    "requestId": "test-123",
-    "request": {
-      "contents": [{"role": "user", "parts": [{"text": "say hi"}]}]
-    }
-  }'
-```
-
-### 10.3 Token Info
-
-```bash
-TOKEN=$(python3 -c "import json; print(json.load(open('$HOME/.cache/codex-proxy/google-antigravity-oauth-token.json'))['access_token'])")
-curl -s "https://www.googleapis.com/oauth2/v3/tokeninfo?access_token=$TOKEN" | python3 -m json.tool
-```
-
-### 10.4 Common Errors
-
-| Error | Cause | Fix |
-|---|---|---|
-| 404 "Requested entity was not found" | Wrong model ID (display name instead of slug) | Check alias_map |
-| 404 on `/v1/models` | Antigravity has no models REST endpoint | Proxy returns static list |
-| 404 on POST /responses | Codex CLI routing issue, not Antigravity | Check proxy is running |
-| 503 "No capacity" | Model exists but overloaded | Try another model or endpoint |
-| 500 "Unknown Error" | Model ID exists but broken on server | Known for gemini-3-pro-low |
-| PERMISSION_DENIED (gRPC) | Token lacks scope or empty request body | Use REST API instead |
-
----
-
-## 11. Version History (Antigravity-specific)
-
-| Version | Date | Change |
-|---|---|---|
-| v3.10.3 | 2026-05-25 | **Fix 404**: Verified REST model IDs, display→slug mapping |
-| v3.10.2 | 2026-05-25 | Wrong fix: tried display names (didn't work) |
-| v3.10.0 | 2026-05-25 | Provider model editor, static Antigravity model list |
-| v3.9.9 | 2026-05-25 | Refreshed Antigravity models (slugs were wrong) |
-| v3.3.0 | Earlier | Initial Antigravity OAuth + tool calls + SSE streaming |
-
----
-
-## 12. Testing a New Model ID
-
-If new models appear in the agy CLI, verify them against the REST API before adding:
-
-```python
-# Test a candidate model ID
-import urllib.request, json, os
-
-token = json.load(open(os.path.expanduser("~/.cache/codex-proxy/google-antigravity-oauth-token.json")))["access_token"]
-wrapped = {
-    "project": "voltaic-hangout-z1qhf", "model": "NEW-MODEL-ID",
-    "requestType": "agent", "userAgent": "antigravity",
-    "requestId": "test-123",
-    "request": {"contents": [{"role": "user", "parts": [{"text": "say hi"}]}]},
-}
-req = urllib.request.Request(
-    "https://daily-cloudcode-pa.sandbox.googleapis.com/v1internal:generateContent",
-    data=json.dumps(wrapped).encode(),
-    headers={"Content-Type": "application/json", "Authorization": f"Bearer {token}", "User-Agent": "antigravity/2.0.1 darwin/arm64"},
-)
-try:
-    resp = urllib.request.urlopen(req, timeout=15)
-    print("OK:", resp.read().decode()[:200])
-except urllib.error.HTTPError as e:
-    print(f"{e.code}:", e.read().decode()[:200])
-```
-
-Then update:
-1. `alias_map` in `translate-proxy.py` — add display name → REST slug mapping
-2. `_ANTIGRAVITY_MODELS` in `codex-launcher-gui` — add display name to list
-3. Preset in `codex-launcher-gui` — add display name to `"Google Antigravity (OAuth)"` models
-4. Context sizes in `translate-proxy.py` — add model ID to `_MODEL_CTX` dict
