Current docs still describe separate Test/Speed screens and h3 as the speed default, omit a general profile/SSH/routing guide, and leave app ownership checks out of the F-Droid listing. Refresh the EN/RU user documentation and store metadata so the current features and their limits are easy to find.

• Add a profile/routing guide covering all transports, SSH authentication and rotation, Jump, failover/Always-on, transfers and device-local controls. Shorten both documentation indexes and retain their existing SOCKS5/Jump anchors.
• Put optional Android 10+ app ownership checks near the start of README and in both short/full F-Droid descriptions. Keep the Standard stale-permission window, shared-UID/unknown-owner limits, compatibility costs and opt-in/reconnect rules explicit.
• Correct Diagnostics/speed navigation, h2 default and shared-log retention, including copies in the rotating diagnostic log; update the privacy policy. Remove duplicated setup/metric/update explanations and clarify that transport benchmarks bypass source validation.

Validation: checked all 31 README/user-guide Markdown files for local paths and heading anchors (no broken links); EN/RU F-Droid HTML and short/full description lengths; compared UI labels and behavior with production code; git diff --check. Existing CI change classification selects no native/Android/Python/emulator suites for these documentation/metadata-only changes. Historical changelogs and generated artwork are unchanged.
