Lowercased tag — 997 functional acknowledgement

A functional acknowledgement whose ISA segment tag arrived in lowercase ('isa'). x12-tidy uppercases it; nothing else is wrong and the result is conformant.

Functional groups	1GS segments counted while walking the payload; IEA01 is checked against this.
Transaction sets	1ST segments counted; each group's GE01 is checked against its own count.

Repair passes

Each pass runs x12-tidy once. Pass 1 works on the interchange as submitted and does the structural repairs. Pass 2 (and any later pass) runs on the previous pass's output, so it shows only what is still wrong after those repairs. The loop stops when a pass changes nothing or finds nothing.

The Byte column is the offset into the submitted text where the flagged structure begins; ISA-line findings share a number, and a dash means the finding isn't tied to one spot.

Hover a severity chip for what it means.

Severity	Code	Byte	Finding
ERROR	`isa.identifier-lowercase`	0	ISA segment identifier is not uppercase the ISA segment identifier is not uppercase ('isa' or mixed case); X12 segment identifiers are uppercase. Parsed case-insensitively. The segment identifier was found as 'isa' or mixed case (e.g. 'Isa'). X12 segment identifiers are uppercase. x12-tidy matched it case-insensitively and continued -- a file with a non-uppercase ISA identifier almost certainly has every other segment identifier the same way, which downstream steps must also tolerate.
