Subject: [PATCH 02/10] fix(web): load dock projects on first use and keep a
 no-dock fallback

Format the PrepareReason union so CI passes. Read the projects list only
after the dock is first opened, skip the embedded Assistant's own projects
read, and let useProjectChat fall back to the Assistant links outside the
workspace dock instead of throwing.

Subject: [PATCH 03/10] fix(web): keep the project chat dock open across pages
 and lighten its load

Collapse on focus only for controls the panel hides, not frame bodies. Add a phone scrim and bottom sheet and reserve scroll space on desktop. Cap mounted chat sessions at 3 without dropping drafts or running chats. Read planner prefs, AI capabilities and agent settings once for all embedded chats.

Subject: [PATCH 04/10] fix(web): stop programmatic focus collapsing the
 project chat dock and share its reads

Collapse only for focus that follows a Tab, never for frame containers. Count an unconfirmed project draft as unsent. Share one assistant controls instance and refresh identity when the dock opens. Skip scroll reserve on short desktops and keep focus inside the phone sheet.

Subject: [PATCH 05/10] feat(ai): give project chats their scope and view on
 every run

Rebuild a chat's scoped project or task facts at the start of every run
attempt, including resumes, using the job owner's current access. A scope
that lost access or was kept out of the assistant now stops the run before
any provider call; before, the facts were checked at admission and then
dropped, so the model never saw the selected project.

Name the selected scope in the lead and specialist prompts, and accept an
optional view (pane, app path, query) with each turn. The server derives
any selected task, page or project from the path, drops it unless the
person may show it to the assistant, and takes titles from the database.

 ## Chats and Activity
 
 **Chats** groups the personal Orbyn conversation, project chats, pinned chats
-and recent chats. New project chats require a project before sending. **Activity**
+and recent chats. New project chats require a project before sending. A chat's
+project or task scope is fixed once it starts. Every run attempt, including a
+resume, rereads that scope with the person's current access and names it to the
+assistant; a scope that was kept out or became inaccessible stops the run before
+any provider call. The web workspace dock also sends the working pane and route
+with each turn. The server derives any open task, page or project from the path,
+drops it unless the assistant may read it, and treats it as location, not as a
+request or a change of scope. **Activity**
 opens Background, Overnight and Upcoming work. Execution jobs remain independent
 of the conversation that receives their results.

Subject: [PATCH 08/10] fix(ai): respect read rules for the open item and keep
 finalization off scope reads

Under restrictive read rules, name the open task or page by screen only, so
a denied space's title never reaches the model. A reviewed answer only
finalizes, so it no longer rereads the scope: an applied plan is not
reported as failed because its task was deleted or its project kept out.
Quote titles in the scope line as one bounded, escaped line, and make the
new run tests match their own chat's requests.
