+● No elisp layer. The message "no such function" is likely the user's paraphrase
+  of tool-bar-mode is undefined from execute-command!. Even though the

-● The newer jerboa (f6d1957) has exactly what the parent expects: a make jerboa
-  target producing the dist/jerboa multicall binary, and dist/jerbuild with
-  transpile/exec/compile/binary subcommands. Updating the vendored checkout is

+● Functional verification is conclusive:
 
-● Now the architecture is clear: /deps/jerboa is baked into the
-  jemacs-deps:x86_64 image. The build syncs host lib/std and lib/jerboa into it,
-  but not jerbuild.ss — so the container transpiles pcre2 with the stale
-  image's jerbuild.ss (3-library expansion) against the freshly-synced new
-  jerboa libs, causing the match collision. Let me see how the deps image is
-  built so I can refresh it.
+  - tool-bar-mode → echo alternates "Tool-bar mode enabled" → "Tool-bar mode 
+  disabled" (with error? = #f), proving the visibility flag flips each call.

-● The container re-transpiles pcre2 with the image's stale
-  /deps/jerboa/jerbuild.ss. Note scintilla and jerboa-qt instead copy 
-  host-transpiled .sls (lines 48-49, 67-68) rather than re-transpiling — pcre2
-  is the odd one out. The robust fix is to refresh /deps/jerboa in the image.
-  Let me check the Dockerfile to see whether a rebuild is incremental (Qt6/Chez
-  layers cached) or a full 45-60 min rebuild.

-● The Dockerfile copies jerboa-src into /deps/jerboa late (line 261), but
-  rebuilding the whole image is heavy and the baked pcre2/sci/qt contexts are
-  also stale. The cleaner, documented fix (CLAUDE.md: "add to the sync list") is
-  to sync the host's current jerbuild.ss into /deps/jerboa at runtime, matching
-  the existing std/core sync. Let me confirm which jerbuild scripts the
-  container invokes and that the new jerbuild only needs (jerboa build).
