MethodMesh v2.2.7

This release tightens native close-out behaviour and admits a first group of reviewed prototype capabilities into the Development lane.

Highlights

Added a public Android Downloads close-out action for native preset, protocol and schedule results.
Added first-pass guided rails for multi-step preset/protocol/schedule runs.
Improved combined protocol outputs so steps can progress and finish on a shared result screen.
Reviewed and admitted Acoustics, Compass, Psychomotor Vigilance Test, Sampling and Sound Generator as Development capabilities.
Hardened ML Kit language handling for conversation translation and shared language-pack settings.

Native result screens now include explicit actions for sharing, copying, saving to Downloads, exporting the full audit package and closing.
“Save to Downloads” writes text/data results as result.txt and writes media as files under Downloads/MethodMesh/....
Full audit export remains separate from simple user-facing sharing and Downloads output.
Protocol and scheduled runs now collate step outputs into one final run result screen instead of leaving each preset sitting on its own result page.
Audit-mode output now retains capability-owned *_audit_json fields without adding them to compact core sharing.

Added Acoustics for local microphone-based pitch/frequency analysis, tuning, sound level estimation and tone comparison.
Added Compass for magnetic heading and bearing-sighting workflows.
Added Psychomotor Vigilance Test (PVT) with 10-minute PVT and 3-minute PVT-B modes, compact results and trial-level audit JSON.
Added Sampling for reproducible sampling/shuffling/partitioning workflows with auditable outputs.
Added Sound Generator for local tones, noise and sweeps with playback provenance.

These capabilities remain in Development until their module-specific device, preset and ODK validation items are closed.

Canonicalised ML Kit language codes and common aliases, including Chinese, Japanese and Korean.
Improved conversation-translation speech locale mapping.
Improved shared language-pack settings feedback and downloaded-language sorting.

Updated the capability writing guide to reinforce the canonical “one module folder with nested docs and XLSForm” delivery contract.
Updated 000_Roadmap.md with the admitted Development capabilities, remaining validation notes and completed close-out work.

PVT remains Development because Android device timing/latency has not yet been physically characterised.
Sampling CSV creation/input still needs real device validation.
The not-yet-ready prototype queue still contains capabilities that either do not build or need deeper review before admission.
Exchange-rate selection/value handling remains on the roadmap for a later pass.
