PROBLEM
-------
Upstream commit b98c94b added 7 comment lines (;; PASSIVES, ;; SEMICONDUCTORS,
;; INTEGRATED CIRCUITS, ;; CONNECTORS, ;; POWER/REGULATORS, ;; MISC,
;; TEMPLATE INSTANCES) to template_with_symbols_expanded.kicad_sch.
KiCAD's S-expression parser does NOT support any comment syntax.
It expects every non-empty line to begin with '('. These comments caused
KiCAD 9 to refuse opening any schematic generated from this template:
Expecting '(' in <file>.kicad_sch, line 8, offset 5
AFFECTED USERS
--------------
Any project whose .kicad_sch was generated by the MCP server after upstream
commit b98c94b and before this fix contains the same invalid lines. Those
files must be repaired manually: open the .kicad_sch in a text editor and
delete every line beginning with ';;'.
FIX
---
Remove all 7 ;; lines from the template. No functional change — the comments
provided no information that is not already evident from the symbol names.
ALSO
----
CHANGELOG: add critical bug-fix entry for this regression under v2.2.2-alpha
