# Current production notes — 10 October 2026

The four documents form a **layered reference**, not four independently updated
snapshots of the same production state. The source texts below are reproduced
unchanged in the downloads and reading pages for provenance; historical lock
values remain visible as a development record.

## Current accepted corrections and clarifications

- **Movement 3 — Tecum principium:** the accepted **final** hidden calibration is
  soprano solo **0.7665**, piano **1.4741**, visible sliders 70%, master gain
  **1.0000**. This supersedes historical tables showing soprano 1.00 and piano
  9.00, which described an older rendering configuration. The separate
  Movement 3 balance final-lock manifest remains authoritative for the installed
  audio and checksum snapshot.
- **Movement 10 — Gloria Patri:** accepted chorus/piano hidden calibrations at
  visible 70% are S1 0.5357, S2 0.5357, Alto 0.5357, Tenor 1.1800,
  Bass 1.6000 and piano **1.7786**. The piano v3 reduction contains the
  separately documented cello bars 122–125 corrections, and the accepted vocal
  USTX retains once-only timing randomisation on Soprano II and Tenor.
- **Modular player architecture:** the `v1 FINAL` shared-engine design continues
  to be used for all ten movements. The companion architecture document's
  production examples and accepted-level tables stop at Movement 8. Refer to
  later final-lock records and the Movement 10 methods addendum for M9/M10.
- **Répétiteur rendering architecture:** the listed rendering method remains
  canonical. Its examples stop at Movement 8; the Movement 10 cello issue is a
  documented instrument-extraction/edition-override case, not proof that the
  original vector parser was comprehensively replaced. The M10 instrumental
  reconciliation validator is an additional QC layer.
- **Stage-1 parser v4:** documents the frozen **vocal score-extraction**
  infrastructure for Movements 8 and 9. It should not be described as a fully
  general updated instrumental parser for all ten movements.
