         `usePanelMemory`. A key collision between those namespaces would produce exactly this: one panel's
         text arriving in another's buffer, with no server involvement and nothing persisted.
 
-      First moves, in order: reproduce with a job whose output is distinctive (`seq 1 100000`), then check
-      whether the editor's content state or only its RENDER is affected — `Cmd+S` at that moment answers it,
-      as does closing and reopening the tab. If the buffer really is clean and only the view is wrong, the
-      suspect is a shared component instance; if the buffer is polluted, it is a key collision.
+      **Screenshot 2026-08-16 answers the first question and kills two theories.** The tab carries a DIRTY
+      dot, and the log lines have Monaco line numbers continuing the file's own sequence (…180, then eight
+      lines of dotenv/POSTGRES_URL output, then 189 `</Link>`). So the MODEL was mutated — this is the
+      editor's content state, not its render, and the earlier "the file was okay" means it was simply never
+      saved. Note the splice is mid-file, not a replacement: JSX text and log text share line 180
+      (`Forgot?--env-file=.env --watch src/server.tsx`).
+
+      Ruled out by that: `CodeSurface` renders with shiki, not Monaco, so the two cannot share an editor
+      instance. And the app's only other Monaco mount (`FileViewer/renderers/EditorRenderer.tsx`) passes no
+      `path`, so its model URI is `inmemory://model/N` and cannot collide with the editor's `file:///…`.
+
+      So the pollution arrives as TEXT through the editor's own content path — `openFile`, `setContent`, or
+      the end-of-turn refresh that re-reads every clean file. That last one is the prime suspect: it is the
+      only thing that writes a buffer without a keystroke, it runs exactly when a background job is
+      producing output, and it lands its result by path.
+
+      One thing to rule out first, because it is mine and it is recent: `2b70a570` gave `<Editor>` a real
+      `path`, so models are now keyed by file URI globally rather than being per-mount `inmemory://`. Two
+      panels open on the same file now share one model. That should be an improvement, but it is a change
+      in exactly the layer that turned out to be involved.
 
       Worth noting because it is the reason to look at all: an editor that can show content the file does
       not contain is a correctness problem even when it never writes — the next person's instinct will be to
