J11 (Conn_JTAG10-mini has placeholder LCSC part number "Cxxxxxx"

[ringof]

Problem

The JTAG connector J11 (Conn_JTAG10-mini) carries an unfilled placeholder LCSC part number, Cxxxxxx, instead of a real one.

Reference : J11
Value     : Conn_JTAG10-mini
LCSC Part#: Cxxxxxx      <-- placeholder, never filled in
dnp       : yes

Impact

• J11 is currently dnp=yes, so with EXCLUDE DNP: true in fabrication-toolkit-options.json it is omitted from the fab BOM — no immediate assembly risk.
• However, the placeholder is a latent defect: if J11 is ever un-DNP'd for a build, the BOM would carry Cxxxxxx and the JLCPCB order would fail or pull the wrong part.
• It is also the kind of error a BOM/LCSC lint in CI should reject outright.

How it was found

Auditing the schematic LCSC Part # fields across all sheets. Every other part is internally consistent (each value maps to exactly one LCSC number and vice-versa). J11 is the sole part with a non-catalog LCSC value.

Recommendation

1. Determine the correct LCSC/JLCPCB part number for the JTAG10-mini connector and set it on the J11 symbol.
2. If no JLC part is intended (hand-assembled/optional), clear the field rather than leaving a Cxxxxxx placeholder.
3. Once a CI LCSC lint exists, this class of placeholder should fail the check.
