 ## What Changes
 
-- Add integration with OpenCode SDK (`@opencode-ai/sdk`) to communicate with the server
 - Collect currently open note paths from Obsidian's workspace API
 - Collect currently selected text from the active editor (if any)
+- Create a new OpenCode session when the OpenCode view is first opened (per Obsidian run)
+- Preserve and restore the last OpenCode iframe URL when the view is closed/reopened (until Obsidian is restarted)
+- Resolve the target session by parsing the `sessionID` from the current iframe URL when context is about to be injected
 - Inject open notes and selected text as context into the current OpenCode session using `session.prompt({ noReply: true })`
-- Use revert + re-inject pattern to prevent context accumulation (each update replaces previous context)
+- Replace previous injected context without using `session.revert()` (update/ignore the previous context part instead)
 - Debounce workspace change events to avoid flooding the server
 - Add settings to enable/disable the feature (enabled by default) and limit the number of notes included
