-## Panel-pointer replay (parent acceptance 48) — ACTIVE, 1b's prerequisite
+## Panel-pointer replay (parent acceptance 48) — MERGED as #243 (`6c9bae6`)
+
+- **MERGED 2026-08-29T10:37:10Z** at approved head `b8c51b7`, merge
+  commit `6c9bae6`, via `--match-head-commit` so the merge is provably
+  of the reviewed head. **14/14 CI green on that exact head**, and the
+  16-stage local gate green on it too (log
+  `20260828T083948Z-492737`), with `HEAD` and a clean worktree
+  captured before and after the run.
+- **Acceptance 48 is now implemented.** Panel selection, terminal
+  mouse reporting and the vertical wheel all replay; the gesture also
+  *ends* correctly, which was the larger half. The horizontal
+  document-panel wheel remains a **named deferral to GUI Stage 1b
+  B1–B3**, not a gap.
+- **GUI arc 1b is UNBLOCKED** and rebases onto this merge.
+  `docs/gui-stage1-input-framing.md` revision 13 already amends B1–B3
+  to own the panel-document horizontal surface that this lane's
+  re-measurement exposed as unowned.
+- **`docs/ci-red-signatures.md` gained U12** through this lane, and it
+  arrived with the merge rather than needing separate absorption.
+- **Two follow-ups are OWED and deliberately unstarted**, both their
+  own lanes:
+  - **`workflow_dispatch` on `ci.yml`.** A merge-base control could
+    only be obtained by re-running an existing week-old job; there is
+    no way to run CI on `main` on demand. That shaped the whole U11
+    recurrence handling.
+  - **The `duration_ms` diagnostic.** `dispatch_parse_round_trips_a_rust_source_file`
+    has now redded twice on macOS/`lua54` (U11, then again on #243)
+    and passed on rerun both times, with `src/async_runtime.rs`
+    byte-identical to main throughout. **Both margins are
+    unrecoverable**, because the assertion omits the measured value —
+    so occurrence two cannot be compared with occurrence one, and a
+    third will be no better. Intermittence is established; cause and
+    magnitude are not.
