> h2. Problem
> When GET /state is truncated (totalEntryCount greater than the returned entries; cap is 5000 via SortedStateUtils.MAX_COMPONENT_STATE_ENTRIES), the Component State dialog already sets partialResults and shows “Showing partial results.” Per-entry delete is still offered.
> Clear-entry does not send “delete this key.” The UI POSTs the *visible remainder* of the map. The server requires that payload to be the *full live map minus exactly one key* (StandardComponentStateDAO.hasExactlyOneKeyRemoved). A partial listing fails that check with:
> Unable to remove a state key for component … Exactly one key removal is supported.
> Reproduced on DebugFlow with Generate State Entries above the GET cap (e.g. clearing debug_state_key_00000).
> h2. Fix
> When partialResults is true:
>  * Do not offer per-entry delete (hide or disable the actions column)
>  * Do not dispatch clearComponentStateEntry
>  * Keep *Clear state* for the whole map
>  * Optional tooltip/copy explaining why single-entry clear is unavailable on a partial listing
> h2. Out of scope
>  * Changing the clear-entry API
>  * Raising the 5000-entry GET cap
