Module Case Studies (Article-Derived)

Article-derived case studies for specific ECU/BCM/immobilizer/module families named in the OBDII365/XhorseTool article imports. Each case study is a single reported example, not a universal support claim. Sensitive key/immobilizer operational detail is intentionally summarized, not reproduced, per the source folders' own import policy and this repository's authorized-use boundary (see 07_Authorized_Key_Immobilizer_Work/README.md).

Evidence status

All entries are COMMUNITY/VENDOR REFERENCE, sourced from exactly one article each (see citation). None are promoted to PRIMARY-MULTIPROG. Where the source did not state a detail, this file uses SOURCE VALUE UNCLEAR.
