 -- 3. EVERY LISTING IS ASYNC. `pmacs.fs.read_dir` is worker-dispatched,

+--
+--    * Errors MUST be `pcall`ed and reported here, and that is
+--      load-bearing rather than tidy. An uncaught raise inside a
+--      `pmacs.async` coroutine reaches `step()`, which reports through
+--      `pmacs.error` --- a channel that **is never defined in
+--      production** (`COHERENCE.md` §1.1) --- and so falls through to a
+--      bare `error()` inside `pmacs._async.tick()`, whose result
+--      `EditorState::tick_async` discards with `let _ =`. The failure
+--      would not reach the status line, the `*errors*` buffer, or a log:
+--      it would reach nowhere, and dired would look like it silently did
+--      nothing.
+--    * Reporting therefore goes through `pmacs.editor.set_status`, which
+--      exists and which the acceptance suite observes --- the corollary
+--      COHERENCE draws from that dead channel: report through a surface
+--      a test can see, or the guard is indistinguishable from the
+--      silence it was meant to fix.
+--    * `pmacs.window.*` calls made after the await act for the *ambient*
+--      active frontend, since interactive origin does not survive the
+--      tick boundary; and `pmacs.editor.move_to_line` acts on the
+--      ambient *buffer*, which is why every post-await re-seat is
+--      guarded (see `seat_cursor`).

+- **Canonical main integrated at `46a1b8f`** (multi-root LSP affinity
+  #161), merged rather than rebased per the #135/#137 precedent so the
+  review anchors stay addressable. Two things worth carrying:
+  - **A conflicting PR silently stops running CI.** GitHub builds
+    `pull_request` runs against the merge ref, which does not exist while
+    the PR conflicts, so no run is created and nothing reports a
+    failure — the checks list simply stays as it was. Three pushes to
+    this branch produced no CI at all before the cause was found. Watch
+    `mergeable` on a long-lived lane, not just the check list.
+  - #161's own COHERENCE finding **falsified a claim in this lane's
+    module doc**: `pmacs.error` is never defined in production, so an
+    uncaught raise inside a `pmacs.async` coroutine does not reach
+    `*errors*` as the comment said. It reaches a bare `error()` inside
+    `pmacs._async.tick()`, whose result `tick_async` discards with
+    `let _ =` — i.e. nowhere. That makes dired's per-coroutine `pcall` +
+    `set_status` load-bearing rather than tidy, and the comment now says
+    so.
