/create seals a person's file into a .dkc of format 2 and, when asked, a
portable .dkk, in the browser and without network, with the decisions the
author confirmed in step 6: time_only by default, the zone of the device
with a selector, the warnings of §53 and §50 beyond 365 days, a notice of
preliminary protocol, and files named capsula-<opening time, UTC>.
- lengths.ts: sealedControlLength moves out of writer.ts, and
capsuleLength gives the size of the .dkc before writing it; the
property loop checks it on every capsule (500 seeds pass).
- datekey.ts: LONG_HORIZON_SECONDS and isLongHorizon.
- src/lib/inspector: localtime.ts (local times of a zone as UTC instants,
a skipped time refused, a repeated one taken at its later instant),
create-input.ts (the form, checked in its order) and creator.ts (the
writing, loaded on demand), all at 100 %.
- The .dkc goes to an OPFS temporary file, committed only when complete
and checked, or to memory up to 64 MiB; the writing can be cancelled.
The .dkk stays in memory only; losing it when it is the only
credential asks for confirmation.
- /inspect also cleans the temporary files of /create, and check-build
checks the code loaded on demand of both pages.
Checked in the browser on the production build: a capsule made for four
minutes later opened afterwards in /inspect with the pasted release and
with datekeys decrypt of Go over the network, to the same content. An
adversarial review found one major and eight minor issues, all fixed.
