Two open candidates, staged until a third reopens the pass.
P13-S1: 169 of core_spec's 207 requirement blocks carry no \label, so no
conformance claim can cite them. The audit that surfaced this scoped it to
Chapter 4 (9/9 unlabeled). It is not a Chapter 4 problem: Determinism Contract
is 15/15, Semantic Operations 24/27, The Score Graph 22/28, Pitch 10/13. Every
req:* label this repo cites was added ad hoc by whichever pass needed it.
P13-S2: cmn-24 is in the built-in pitch-space table as "CMN extended with
24-EDO quarter-tone accidentals" and cannot be represented -- Cmn.alteration is
an i8 of whole semitones, and a quarter-tone is half of one. Blocks Push 4b.
Also parked: the Push 4b prerequisites. Push 4a proved transposition needs no
tuning catalog; what the catalog is still for -- resolving a scale position to
a frequency, applying an instrument's transposition at the written/sounding
boundary -- remains, and Chapter 4 is not implementable as written.
Two further claims from the audit are recorded as UNVERIFIED rather than
inherited: that the JI dimension convention conflicts with its own prime-2
requirement, and that the named historical tunings lack exact ratio data.
Neither was needed for 4a; neither was confirmed. An audit finding that has not
been executed is a hypothesis.
