What it is​

TAP is associated with some Happy embroidery machine workflows and conversion tools.

Satin Studio direction​

Possible import after DST/EXP if files appear.

Versions and variants​

TAP may be closely related to DST stitch data without the 512-byte DST header. If that relationship holds for user files, Satin Studio could reuse a DST stitch decoder while handling missing header metadata explicitly.

File identification notes​

Reported structure is DST-encoded stitches with no DST header. That means labels, extents, and counts may need to be recalculated instead of read.

Observed structure notes​

  • Observed TAP readers parse the file directly as DST three-byte stitch records with no 512-byte header.
  • Because the header is absent, label, extents, stitch counts, and color-change counts must be recalculated or supplied externally.

Structure sketch​

TAP is reported as DST-compatible stitch data without the 512-byte DST header.

struct TapCandidate<'a> {
    records: &'a [DstRecord],           // reported headerless DST body
}

struct DstRecord {
    b0: u8,
    b1: u8,
    b2: u8,
    // decode with DST weighted movement and command bits if compatibility is proven
}

What we still need​

Happy-machine files, confirmation of DST-compatible body encoding, and reader validation.
