A prerendered static site (adapter-static) with a landing page and
/inspect, which runs spec §63 steps 1 to 8 on a .dkc chosen with the file
picker, dropped anywhere on the page, or taken from the official fixtures
bundled at build time. It shows every step, the decoded header, the unlock
date in UTC and local time, and each extension's id, version, criticality,
length and hex, with a text view and an informative CBOR diagnostic view,
all escaped and labelled as unauthenticated before step 15. Copiar JSON
copies the exact "datekeys inspect -json" view.
No network: a hash-mode Content-Security-Policy with connect-src 'self'
is the first element of every page, and scripts/check-build.mjs verifies
it, the fixtures and the absence of external URLs after every build.
Large files are read only up to what steps 1 to 8 need.
Reviewed for design and accessibility (WCAG AA contrast, keyboard,
focus, live status, 360 px), security and correctness; 262 tests pass,
svelte-check has no warnings.

Canonical CBOR codec of the spec §58 profile, hand-written schema codecs
(profile, PUBLIC_HEADER, CONTROL_CBOR, .dkk, extensions), DKC1/DKK1
framing, a strict age header parser, dk1_ parsing and nanosecond date to
round resolution, and inspect (spec §63 steps 1 to 8) with the same checks
and view as "datekeys inspect -json". No runtime dependencies.
216 tests, cbor.ts at 100 % coverage, typecheck of the library without
Node types. A differential comparison with the Go reference at afb44a3
found no verdict, code or step disagreement in about 336,000 inputs. The
harness for the future Go vector files runs them when they appear.
vite 8.3.0 is declared explicitly: it is a required peer of vitest 5.0.1
that legacy-peer-deps does not install.
