storage.md's BackendProvider listing and its notes predated #65: the
trait gained upgrade_endpoint (core/dr-sync/src/provider.rs:95), run at
launch by AccountStore::upgrade_endpoints to move an http:// account to
https:// with its keyring entry, and the Nextcloud client refuses plain
http below every URL it sends (adade27, ea31791, 5569a06). The listing
gains the method and a note says why it is not normalise_endpoint again.
docs/ had 26 developer documents flat beside the manual, and the two
audiences are very differently sized: most readers want the manual and
the gesture reference, a few want the register, the designs and the
measurements. The manual and gestures.md stay at the top; everything for
someone changing the code moves to docs/dev/, and the two documents that
name their own successors — the v0.1 milestone and the UI-refinement plan
— go to docs/dev/archive/ rather than being deleted, since both are still
cited. docs/README.md is the index, users first.
Every reference follows: code comments, Cargo manifests, the workflows,
the pre-commit hook, the bench and traceability tools (which locate the
repo root by docs/dev/requirements.md now), packaging, the Docker READMEs,
CLAUDE.md, CONTRIBUTING.md and the README. The matrix links one level
deeper and is regenerated. Links out of the moved documents into the tree
gain a level; a link checker over every Markdown file finds none broken.
