 ## Goal
 Capture still images from Nest cameras (Google Nest SDM API) for AI (Ollama) analysis.
 
-## What Was Built (Previous Session)
+## What Was Built
 Custom integration `nest_snapshot` at `/homeassistant/custom_components/nest_snapshot/`:
 - `manifest.json`, `services.yaml`, `__init__.py`
 - Uses WebRTC (`aiortc`) to grab one video frame → saves as JPEG
 - Test automation `automation.test_nest_snapshot_capture`
 
-## What Was Fixed (This Session)
-### Bug: `Nest integration data not available for camera.front_door_front_door`
+## Bug Fixes Applied
 
-**Root cause:** The integration was written for an older Nest SDM API. In HA 2026.7:
-1. Nest stores runtime data in `entry.runtime_data` (a `NestData` dataclass), **not** in `hass.data["nest"]`
-2. Camera entity `unique_id` has a `-camera` suffix, but `device_manager.devices` is keyed by the raw Google device name
+### Fix 1: `Nest integration data not available`
+- **Root cause:** HA 2026.7 stores Nest runtime data in `config_entry.runtime_data` (NestData dataclass), not in `hass.data["nest"]`. Camera entity `unique_id` has `-camera` suffix, but `device_manager.devices` is keyed by raw Google device name.
+- **Changes:** Line 69: `config_entry.runtime_data` instead of `hass.data.get(...)`. Lines 78-81: `-camera` suffix stripping before device_manager lookup.
+- **Status:** ✅ Fixed
 
-**Changes in `__init__.py`:**
-- Line 69: Replaced `hass.data.get(NEST_DOMAIN, {}).get(config_entry_id)` with `config_entry.runtime_data`
-- Lines 78-81: Added `-camera` suffix stripping before device_manager lookup
+### Fix 2: `aiortc` module not installed
+- **Root cause:** `aiortc` and `Pillow` not in manifest.json requirements.
+- **Changes:** Added `"requirements": ["aiortc", "Pillow"]` to manifest.json.
+- **Status:** ✅ Fixed
 
-## SDP candidate fix (round 3)
-- Added `re` import
-- Added `_sanitize_sdp()` — inserts missing `1` component ID before `udp` in ICE candidate lines
-- Applied `_sanitize_sdp()` to `stream.answer_sdp` before `setRemoteDescription`
-- Still pending: restart + test
+### Fix 3: SDP format — "Offer must contain audio, video and application m lines"
+- **Root cause:** Only added video transceiver; Google needs audio + video + application in order.
+- **Changes:** Added `pc.addTransceiver("audio", ...)`, `pc.addTransceiver("video", ...)`, `pc.createDataChannel(...)`.
+- **Status:** ✅ Fixed
 
-## To Resume Testing
-1. Trigger automation `automation.test_nest_snapshot_capture` or call `nest_snapshot.capture` on `camera.front_door_front_door`
-2. Check `/media/` for output file (>10 KB = success, ~1-2 KB = placeholder)
+### Fix 4 (current): `invalid literal for int() with base 10: 'udp'`
+- **Root cause:** `aiortc` ICE candidate parser expects `candidate:ID <int:component> udp ...` but Google Nest API sends `candidate:ID udp ...` (missing component number).
+- **Attempt 1:** Sanitize via `_sanitize_sdp()` checking `parts[1].lower() == "udp"` — didn't match actual format.
+- **Attempt 2:** Changed to `not parts[1].isdigit()` — still failing. Possibly the line format is `a=candidate:udp ...` where `parts[0].split(':')[1]` is `udp` and `parts[1]` IS a digit.
+- **Current state:** Added debug logging of raw SDP from Google. Need restart to see logs.
+- **Status:** 🔴 In progress — add logging to see actual SDP format
+
+## File States
+- `__init__.py` — has `_sanitize_sdp()` with `not parts[1].isdigit()` check + debug logs
+- `manifest.json` — has `["aiortc", "Pillow"]` requirements
+- `services.yaml` — unchanged, defines `capture` service
+- `AGENTS.local.md` — restart rule added (must ask each time)
+
+## Pending Changes (committed but not tested after latest edit)
+- `_sanitize_sdp()` now uses `not parts[1].isdigit()` (broader match)
+- Debug logging added for raw + sanitized SDP
+- Need restart → test → check system log for SDP content
