ZacharyZhang-NYandClaude Opus 5.5 fe90221c11 C12.2: read and write MIME by the tree
The reader walks the MIME tree with its container context: alternative
picks versions, related finds its root by start, attached multiparts
stay whole, digest children are messages. Nesting deeper than 64
levels, counting enclosed messages, is refused, and over-deep parse
results are taken apart iteratively so dropping them cannot overflow
the stack. Composite parts with a Content-ID are cid targets.

The writer keeps attachment parameters and Content-IDs, writes
multipart and message attachments unencoded, and makes its own
Message-ID. SMTP adds BODY=8BITMIME for 8-bit bodies and SMTPUTF8
when any header block at any depth is 8-bit.

Build (macOS)

scripts/doctor.sh                 # toolchain versions
scripts/fetch-references.sh       # upstream sources at pinned commits
scripts/build-libreoffice.sh      # patched LibreOffice 26.2.6.3 (about an hour)
scripts/build-mupdf.sh            # patched MuPDF 1.28.5
scripts/build-git.sh && scripts/fetch-git-lfs.sh

cargo build -p ely-lok --bins -p ely-pdf-engine --bins
cargo run -p ely-doc              # or ely-table, ely-show, ely-pdf, ely-tree, ely-mark

Packages: packaging/macos/release.sh writes each app's .app and .dmg, the source archive and the upstream source archive (patched MuPDF, Git) to dist/. Linux and Windows recipes are in packaging/linux and packaging/windows; they have not been run on those systems.

Tests

cargo test --workspace, the window scripts in tests/scripts (macOS, Accessibility permission), and the benchmark tests/perf/bench.py.
