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.

|
# apksigner — are in the image already and are enough on their own, because
|

# the app is Rust: android-activity's glue calls android_main directly, and

# the only Java in the APK is Slint's helper plus the handful of classes
|

# Android insists on constructing itself (see assemble-apk.sh's Java step).
