docs(raw): close the #468 follow-up — raw modals now feed pickers live merged config

Records the outcome in the design doc §6 (including the stale-open race the
review found and fixed in both modals), closes the follow-up in the tracking
doc and the universal-browser plan, and registers RawBrowseModal's shared
race shape in deferment.md §0.1 as the deliberate leftover.

 1. ~~**Full tree-render verification is fixture-blocked.**~~ **CLOSED** by the second gate above.
-2. **Driver-page address pickers pass no live config.** `AbCipDriverPage`/`TwinCATDriverPage`/`FOCASDriverPage`
-   host the same `*AddressPickerBody` but do **not** pass `DriverType`/`GetConfigJson`, so their (now-visible)
-   Browse button would capture against `"{}"` (no device). Out of Task 14's scope (which listed only the
-   TagEditor pass-through); wire the live form config through there too, or hide the Browse affordance on the
-   driver-config picker.
+2. ~~**Driver-page address pickers pass no live config.**~~ — **CLOSED 2026-08-05.** The named
+   `*DriverPage` shells were deleted by v3 Batch 2 before this was ever actioned, but the defect
+   pattern survived into the v3 tag-editor hosts (`RawTagModal` / `RawManualTagEntryModal`, both
+   passing a `"{}"` stub as `GetDriverConfigJson`). Fixed by resolving the merged Driver+Device
+   config (`IRawTreeService.LoadMergedProbeConfigAsync` — the same blob Test-connect and
+   `RawBrowseModal` dial) once per open and forwarding a live accessor; fail-soft on resolve
+   failure. See `2026-08-05-raw-modal-picker-live-config-design.md` for the design and outcome
