The crate's record should hold what the decoder is built from, not the process
that produced it. The starting assumptions, the plan, the container notes, the
entropy-derivation log, the chart calibration, the probe scripts and their
observational logs are not part of it. The frozen-table JSONs and
tools/gen_tables.py stay, so src/tables.rs can still be regenerated and audited.
Renumber the surviving documents 01-05 in reading order and update every
reference to them, so the record reads in order and cites nothing that is no
longer there.
AGENTS.md and CLAUDE.md go back to main: repository instructions are not part of
this change.
The clean-room Canon CRW decoder written in LightCraft (crates/raw/src/vendor/crw.rs,
crw_tables.rs, branch clean-room-crw-format-decode, revision 70c755e4) becomes the shared
crate craft-crw: the CIFF heap container, the entropy coding derived by black-box analysis
(frozen code tables for selectors 0-2), sensor black and white levels, as-shot white
balance, orientation and the make/model/time records. Public types are the crate's own
(Error, Limits, Cfa, Rect, BlackLevel, Header, Image); the capture time is handed on as
Unix seconds so no calendar code lives here; LightCraft's shared plateau estimate is
copied as saturation_plateau. Algorithm, tables and thresholds are unchanged.
Tests: the ported synthetic round-trip, table-structure and hostile-input tests; a
proptest mutation sweep (tests/robust.rs); and tests/samples.rs, which pins the eleven
CC0 raw.pixls.us sample files (tests/samples.json: URL, SHA-256, licence) to the SHA-256
of the verified decode plus levels, white balance and metadata, so the port is proven
byte-identical to the LightCraft decode without redistributing the reference TIFFs.
scripts/fetch-crw-samples.py downloads the files outside the checkout; CRAFT_CRW_SAMPLES
and CRAFT_CRW_ORACLE point the tests at them. The crate builds for wasm32.
The whole derivation record (starting assumptions, plan with the maintainer's decisions,
source log, container and payload notes, derivation log, frozen format, verification,
colour/levels notes, private-corpus and chart notes, scripts, logs and the frozen table
JSON) moves verbatim to crates/crw/clean-room/ with a README that indexes it and maps the
LightCraft paths it cites; tools/gen_tables.py regenerates src/tables.rs from the JSON,
byte for byte.
Repository: .github/workflows/crw.yml (fmt, clippy, tests on Linux, Windows and macOS;
wasm check; the sample-file job with cached downloads), README and ATTRIBUTION rows,
NOTICE source provenance, docs/clean-room.md (the clean-room standard a format crate
follows here), and AGENTS.md expanded with the start-of-session steps, the new-crate
checklist, clean-room, assets and test rules; CLAUDE.md points at it.

- FontStore::remove_files only touches names the family's manifest entry
lists and that are safe file names.
- A user source's folder carries a hash of its full ID, so sources whose
IDs slug alike don't share a folder.
- The download dialog and the sidebar note name the family's own source,
and the server for a source the user added.
- The face cache takes out only faces the last frame didn't draw.
- The catalog test lists missing translations instead of failing.
- ATTRIBUTION lists the three bundled craft-font-index files.
Conflicts: NOTICE, vendor/README.craft-reader.md and the hayro-interpret and
hayro-syntax SOURCE.json keep the ec0a965 provenance and add hayro-cmap
(a2ec27b) and hayro-postscript (crates.io 0.1.0). type0.rs keeps PdfCraft's
flat sample array with its 64-bit largest sample and main's 32-bit test.
Local sha256 values recomputed for the merged files.
hayro-postscript 0.1.0 is the token scanner hayro-cmap uses for the
CMap streams PDFs embed. Its object reader skipped each `<<` or `>>`
by calling itself again, so a stream holding a long run of `<` or `>`
bytes recursed once per pair and aborted the process with a stack
overflow.
Vendor the crates.io package unchanged and patch `object::read` to
skip those runs in a loop, returning the same next object as before.
Wire it in like the other Hayro crates: workspace exclude,
[patch.crates-io] entry, SOURCE.json with registry and local hashes,
the backend test script, NOTICE, ATTRIBUTION.md and the reader README.
Tests cover a million `<` and a million `>` bytes, `<< /A 1 >>` and
nested `<<<< /X >>>>` runs.
* pdf: keep a CID font's /W2 table past an out-of-range first CID; vendor hayro-cmap from PdfCraft
- hayro-interpret: a /W2 run whose first CID is past 65535 is skipped, as in
/W. A run starting at 4294967295 overflowed the CID counter and discarded
the whole table. Unit test in font::cid.
- hayro-cmap 0.1.0 is vendored from PdfCraft a2ec27b47 with its malformed-CMap
patch (PdfCraft #3177): bad bfchar/bfrange entries, an unresolvable usecmap
and an unparseable tail are skipped instead of failing the whole CMap. The
crate's tests come with it. Wired up like the other vendored Hayro crates
(workspace exclude, patch entry, SOURCE.json, backend test script); NOTICE,
ATTRIBUTION.md and vendor/README.craft-reader.md record the source.
* hayro-syntax: refuse an xref-stream subsection that runs past object number u32::MAX
The object number was start + i in unchecked u32: a subsection starting near
u32::MAX overflowed (a panic in debug builds, a wrong object number in
release). Covered in xref::tests::xref_stream_entries_need_backing_bytes.
* hayro-cmap: a binary usecmap counts against the nesting limit; /W2 checks the CID first
- hayro-cmap: a binary CMap's usecmap passed its own depth to the nested
parse, so a self-referencing binary CMap recursed until the stack
overflowed. It now counts like a text usecmap. Test:
self_referencing_binary_usecmap_stops_at_the_nesting_limit.
- hayro-interpret: the /W2 first-CID check runs before the run's metrics
are read, so an incomplete run past CID 65535 no longer discards the
rest of the table.
* hayro-syntax: refuse xref-stream object numbers past i32::MAX
ObjectIdentifier stores an i32; a number between i32::MAX and u32::MAX
was cast to a negative object number.
`Folder` folds text for case- and accent-insensitive search (Turkish and
Azerbaijani i by locale, ß, final sigma, ligatures, full-width forms) and
maps matches back to the original text for highlighting. `Collator`
(feature `collate`) sorts lists in the locale's order with digits compared
by value, on ICU4X with collation data for the shipped locales only.
The Turkish i and sigma handling come from PdfCraft's `fold_case`.
Part of #198.

Print PDFs written through krilla separated wrongly: transparency groups blended in RGB
(K 50% over C100 separated as C84 M34 Y32 K37 instead of C50 K50), and there was no
overprint, knockout, DeviceN, soft-mask backdrop or print output intent.
Patches in vendor/krilla/patches/, recorded in README.craft.md and SOURCE.json:
- 02 blending color space: GroupColorSpace { Rgb (default, unchanged output), Cmyk }
- 03 overprint: Surface::push_overprint (/op /OP /OPM)
- 04 knockout groups: Surface::push_group(GroupOptions { isolated, knockout })
- 05 soft-mask backdrop and transfer function (/BC /TR)
- 06 DeviceN and NChannel colors for fills and strokes
- 07 DeviceN images and shadings
- 08 print output intent (GTS_PDFX), /Trapped, PDF/X version markers
craft_pdf::write::print::settings(PrintColor) turns them on for print export.
Add Builtin::CoatedFogra39 ("Coated FOGRA39 (fitted, craft-cms)",
profiles/craft-coated-fogra39.icc: AToB 11^4, BToA 33^3, 330% TAC,
medium GCR). It is fitted to Fogra's FOGRA39 characterisation data
(tests/data/FOGRA39.txt, unmodified, 1617 patches): a Yule-Nielsen
Neugebauer model with free overprints, per-ink tone curves and n, plus
a Gaussian-kernel ridge correction of the residuals. Against the
patches, relative colorimetric through the AToB: mean dE00 0.07,
p95 0.18, max 0.53. The BToA tables invert the AToB table
(synth::cmyk_profile_from_model); the Photocraft coated profile and its
synth defaults are unchanged.
Builtin::from_profile_name maps the names documents carry for
FOGRA39-based profiles (Coated FOGRA39, ISO Coated v2 (ECI)) to the new
profile and every built-in by its description. Adds math::delta_e2000.
