RGCS v8.5.2

RGCS v8.5.2 — Frequency Studio CRUD, curated curated corpus library, workspace lifecycle

Frequency Studio becomes a real editor: sessions have New / Open /
Open Recent / Save / Save As / Close / Duplicate / Delete-to-trash /
Import with dirty-state prompts, a stable session identity, and a
Session Library page over the workspace library. 61 curated
curated binaural sessions from an imported frequency corpus (Schumann, sleep, focus/memory,
relaxation/emotional, chakra/pineal, altered-state families) ship as
factory content with a per-file-hash manifest; factory sync is
idempotent — it adds missing files, updates only unmodified factory
copies, and never touches user-edited files. Source-language claimed
uses are recorded, not endorsed; nothing here is a medical claim.

Workspace lifecycle is fixed end to end: first runs and reinstalls
never crash when the workspace folder already exists, a failed
open/create leaves the current workspace usable, and Close / Switch /
Reveal / Repair commands tear down playback and jobs properly.

Exports are selectable by file type: Frequency Studio writes only the
checked types with the expected files listed first, and Phryll v2
exports single artifacts (STL-only among 12 kinds) without a bundle.
Phryll v1 is retired from the UI; v2 is the only Phryll path. Every
PDF sheet's section rules now sit under their text instead of striking
through it, and all demo sheets are regenerated.

The tag-triggered release pipeline now runs the full test suite and
leak firewall as a validate gate before building Windows (portable
zip + per-user installer), Linux, and macOS packages — each
smoke-checked, manifested, and SHA-256'd. All builds unsigned per
project policy.

Designs, estimates, and audio recipes remain model outputs and
reproducibility records. Measurements decide.
