edit-metadata writes EXIF tags in place and streams the original bytes
back, but the response content-type defaulted to image/jpeg for any
format outside a small map. A BMP/PSD/PPM download then claimed to be a
JPEG, and the nightly tool-x-format matrix tried to Sharp-decode it and
threw "unsupported image format".
Map every format validateImageBuffer can report to its real MIME type,
and switch the matrix's pixel-decode gate from a fragile denylist to an
allowlist of formats this libvips build is guaranteed to decode. Niche
raster types streamed back untouched now carry an honest content-type
we simply don't pixel-verify.
Verified green across all 157 tools x 34 formats with FULL_MATRIX=1.
Move all fixture files from flat/mixed dirs (content/, media/, documents/,
formats/, hostile/, root loose) into the modality-first hierarchy:
image/{valid,formats,edge,hostile}, video/{valid,formats,hostile},
audio/{valid,formats,hostile}, document/{valid,formats,edge,hostile},
data/valid/, security/. Update index.ts paths, fixtureDir aliases,
all literal refs in 17 e2e/qa/script files, manifest.json, and the
three generator scripts. 163 files moved, 0 dropped, 100 new tests
from expanded document scan.
