* Use chrono for UTC/calendar conversion instead of hand-rolled copies
Replaces the hand-rolled civil_from_days/days_from_civil copies and the
leap-year/month math around them (log timestamp, PDF /Info dates, ASN.1
UTCTime/GeneralizedTime, FormCalc Date/Num2Date, the Combine modified-time
stamp, the form date picker, and the demo-PDF timestamps) with chrono as a
workspace dependency. The engine's existing chrono (clock) is lifted to the
workspace. Every output format is unchanged and pinned by tests. CLAUDE.md now
says time goes through chrono.
Follow-up to storytold/cadcraft#1785
* Guard chrono date paths: no panic on overflow, no '+' on 5-digit years
Systemic chrono follow-ups to the UTC/calendar PR:
- logging::timestamp and combine_ui::utc_stamp dropped chrono's
From<SystemTime> (which unwraps internally and panics on a clock past
year 262143) for the fallible DateTime::from_timestamp, reading an
out-of-range clock as the epoch, as the old clamping code did.
- timestamp, utc_stamp, pdf_date and the xtask Stamp now write the year
with {:04} instead of %Y, which prefixes a '+' before years past 9999;
the old hand-rolled code wrote the plain zero-padded year.
- forms_ui calendar navigation and length, and formcalc days_in, use
checked_add for the December year successor so y + 1 can't overflow at
i32::MAX / i64::MAX (reachable from a parsed or persisted date).
Docstrings added to the chrono-touched civil_from_days and Time::from_unix
for the docstring-coverage gate. Tests cover the out-of-range-epoch and
10000-01-01 cases for each.
* Don't build an unrepresentable SystemTime in the far-future test
UNIX_EPOCH + Duration::from_secs(u64::MAX / 2) overflows Windows'
SystemTime and panicked before timestamp() ran, failing the Windows
test job. Build it with checked_add and only assert where it exists.
* Keep FormCalc dates exact past chrono's range
MAX_DAYS accepts day numbers up to 1e8 (years past 270000), but NaiveDate
stops near ±262143, so Num2Date(99000000) and Format fell back to
1900-01-01. days_from_civil, civil_from_days and days_in now have chrono
convert within the date's 400-year Gregorian cycle and add whole cycles
back (via i128), which gives the pre-chrono results for every year. Tests
cover accepted inputs past chrono's range on both sides of the epoch,
through Num2Date and Format, with values from the old formula.
* Bump rustls-webpki and webpki-root-certs for RUSTSEC-2026-0382/0383
rustls-webpki 0.103.15 -> 0.103.16 and webpki-root-certs 1.0.9 -> 1.0.10
(both semver-compatible, lockfile only) drop the distrusted emSign
intermediates and root. Only these two entries change; cargo deny check
advisories passes. Upstream main fails the same check.
* logging/cos/sign/combine/demo: keep extended-year dates, no epoch fallback
For consistency with the stricter no-epoch-fallback rule now agreed across the sibling
chrono PRs (wordcraft#3427, filmcraft#2662): `DateTime::from_timestamp(..).unwrap_or_default()`
changes a timestamp the old code converted past chrono's year 262143 range — it collapses
to 1970-01-01 instead of the real proleptic-Gregorian date. The FormCalc Num2Date path was
already fixed (FredApps approved); this applies the same fix to every remaining conversion.
Each site uses the 400-year Gregorian cycle (146_097 days) with chrono as the only calendar
logic: chrono converts the day within one cycle, whole cycles carry in the year (i128,
saturated into i64). PDF/ASN.1 format-specific year handling is kept exactly as the old code
had it. Verified the cycle result equals the old formula across a wide range and at the extremes.
- apps/pdfcraft/src/logging.rs `timestamp`: cycle `civil_from_days(u64)`; pre-1970 epoch clamp
and ms/time-of-day format kept. Pins: +10_000_000_000_000 s -> 318857-05-20T17:46:40.000Z
(was 1970); checked_add u64::MAX/2 s -> 292277026596-12-04T15:30:07.000Z (was epoch).
- crates/cos/src/writer.rs `pdf_date` (i64): cycle converter, no year clamp (old code wrote `y`
as-is, so a negative year keeps its sign). Pins: pdf_date(10_000_000_000_000)="D:3188570520174640Z",
pdf_date(-10_000_000_000_000)="D:-3149180813061320Z".
- crates/sign/src/der.rs `Time::from_unix` (i64): cycle converter; the `year` field is a u32, so
the year is cast `as u32` (wrapping) exactly as the old code did — ASN.1 year width preserved
byte-for-byte. Pins: from_unix(10e12).year=318857, from_unix(-10e12).year=4_294_652_378,
from_unix(i64::MAX).year=219_250_468, from_unix(i64::MIN).year=4_075_720_767.
- crates/ui-egui/src/combine_ui.rs `utc_stamp` (u64): cycle converter; pre-1970 epoch clamp kept.
Pins: utc_stamp(10e12)="318857-05-20 17:46 UTC", u64::MAX/2 s="292277026596-12-04 15:30 UTC".
- xtask/src/demo_pdf/pdf.rs `Stamp::from_unix` (i64): cycle converter, no year clamp. Pins:
from_unix(10e12).iso="318857-05-20T17:46:40Z"/.pdf="D:3188570520174640Z",
from_unix(-10e12).iso="-314918-08-13T06:13:20Z".
cos/sign/xtask built, tested (pdf_dates_are_utc_and_byte_identical, der::tests::times,
stamps_round_trip), fmt and clippy clean. pdfcraft-ui-egui and the pdfcraft app can't link
here (unrelated LLVM intrinsic bug in the rten-gemm dependency, 1.98.1), so their logging and
combine_ui functions + tests were copied verbatim into a scratch crate with chrono 0.4.45 and
pass there; fmt --check clean on all five packages. CI builds these on all platforms.
* Don't build a year-318857 SystemTime unchecked in the logging test
Windows' SystemTime only reaches about year 30828, so
UNIX_EPOCH + Duration::from_secs(10_000_000_000_000) panicked before
timestamp() ran and failed the Windows test job. Build it with
checked_add and assert where the platform can hold it. The year-10000
case fits everywhere and stays unconditional.
* Name the 400-year range extension as the one exception to the time rule
The rule said never to hand-roll calendar math, but the range fix
(shifting by whole 400-year Gregorian cycles so dates past chrono's year
range keep their old output) is cycle arithmetic, so the rule and the code
disagreed. The rule now names that exception: the library still computes
month, day and time, and only whole cycles are carried in the year.
* Say the library computes month and day; time-of-day is plain arithmetic
Narrows the range-extension wording: the date library computes the
calendar fields, and splitting seconds into hours, minutes and seconds
is ordinary arithmetic, which is what the code does.
55 files hand-rolled the same serialiser -- number the objects, record each one's offset, emit a
classic cross-reference table and a trailer -- 111 times over. The object bodies are properly the
business of the crate under test; the envelope around them is not, and every copy is a place for a
fixture to be quietly wrong in a way that makes a test prove less than it appears to.
`pdfcraft-testkit` holds that envelope. It has no workspace dependencies on purpose, so the crates
at the bottom of the layering can use it without a cycle, and it returns bytes rather than a parsed
document for the same reason.
The builder is byte-identical to the serialiser it replaces, asserted against a verbatim copy of
the old code across versions and trailer variations, because a migration that changes a fixture's
bytes silently changes what the test using it proves. Watched failing by breaking the free-entry
generation: three tests caught it. The one intended difference is that an empty stream dictionary
gives `<< /Length N >>` rather than a doubled space.
Migrates cos, measure and redact: 111 copies in 55 files becomes 108 in 53. The rest are
follow-ups rather than one sweep -- ui-egui alone is 27 of those files and is the most contested
area in the repository. Some copies should stay: a test about a malformed cross-reference table
needs to write its own bytes.

Every test that wanted an external oracle probed for it by hand and chose for itself what to do
when it was missing. The common choice -- print a line and return -- reports as a pass, so a suite
with no oracles installed looked exactly like one in which every oracle agreed.
That was not hypothetical. No CI runner installed qpdf, so `qpdf_agrees` had never executed on a
runner, while README.md said saved output was "independently checked with qpdf". For R2-R4 that
test is the only check of owner-password authentication (Algorithm 7) that does not go through our
own code.
`pdfcraft-oracle` holds the probes and one rule: a missing oracle is a declared skip or a failure,
never a silent pass. `PDFCRAFT_ORACLES_REQUIRED` picks which, on the same convention as
`CRAFT_FONTS_REQUIRED`. CI installs qpdf and sets it, so a skip notice there is now a red build.
The crate has no panicking path of its own; `or_skip!` expands its assert into the caller, which
is test code.
Verified by running the qpdf tests against qpdf 12.4.2 for the first time -- they pass, so the
README claim is now both enforced and true. Both gate directions were watched: absent and
unrequired skips with a notice, absent and required fails with the install command in the message.
Only qpdf is installed in CI, because it is the only tool the test job uses. The Poppler pixel
comparison in crates/organize stays ignored until a change turns it on and verifies it there.

The app, crates, binaries, bundle id, packaging, icons, screenshots and docs are now
PdfCraft / pdfcraft (repo storytold/pdfcraft). On first launch the desktop app moves the
PrintCraft settings and crash-recovery folders to the new name, and both apps read settings
saved under the old storage key, so upgrades keep recent files, preferences and unsaved work.
The signing test fixtures keep their PrintCraft subject names (they are binary).
