Category = ABBR is the hard no-drift case inside V50. The abbreviation token itself remains unchanged across retained language lanes and downstream outputs, so case, spacing, punctuation, hyphenation, and letter sequence stay fixed.
ABBR rows remain immutable and are classified as MUST_LOCK: the abbreviation token itself stays identical across language lanes and downstream outputs.
Use this section as a compact machine-readable EFT reference.

If a full expansion is needed, it belongs in NOTE or nearby explanation while the ABBR token itself remains fixed. Paragraph translation may change surrounding grammar, but not the abbreviation surface form. NOTE remains support metadata rather than an alternative ABBR string.
The current ABBR inventory is keyed by E0001–E0008 and consists of EFT, GUP, PER, STG, TBN, TCW, TPR, and TWall. These tokens are marked MUST_LOCK and remain frozen in title, one-liner, keywords, C.text, D.note, and batch/process records.
