 Status as of 2026-03-31 when codex credit ran out:
-1. Removal of plugin did not work.   Need to set all files owner to www-data.
 
-2. Deletion of event in ui doesn't delete event in thunderbird
-3. Cannot subscribe to an empty calendar in thunderbird
-4. Click inside month cell doesn't add event.
-5. Login pane hidden under website hero/banner image
+1. Removal of plugin did not work.   Need to set all files owner to www-data. - done
+2. Deletion of event in ui doesn't delete event in thunderbird - done
+3. Cannot subscribe to an empty calendar in thunderbird - ok
+4. Click inside month cell doesn't add event. - cannot reproduce
+5. Login pane hidden under website hero/banner image - done
 6. Updating an events description via caldav creates weird sequences, e.g.
-a space ends up as: text/html,%C2%A0":
+   a space ends up as: text/html,%C2%A0":
+7. In a private window, Click on event from not-logged-in calendar page shows event as a dialog box,  it should show it as a panel with a subset of the edit event panel - i.e. the title, category, location, start and end and description.  -
+8.

+4. Validate extracted plugin directory structure.
+5. Synchronize extracted plugin directory to deploy directory.
+6. Run post-deploy verification checks.

+Additional policy requirement:
+- Deploy flow should not bypass packaging by deploying an arbitrary stale artifact path; deployment must use the freshly built artifact for that deploy run.
+- Deployment tooling may support an explicit version override for controlled releases (for example `1.0.0`); when used, that explicit version must be the packaged and deployed artifact version for that run.
 
 ## Exact-Match Validation (Required)
 After deployment, deployed plugin files must exactly match the approved artifact contents (excluding allowed mutable runtime files if any are explicitly listed).
