Chord quality on the one-chord-a-bar sheet: the hint carries most of the loss, and a style-neutral clause recovers some of it

Drafting

Study Overview

Where the Quality Goes

For each of Study 43's 24 guitar cells the bench recomputed the per-bar hints with the same chord model, took the sheet's chord at each bar as truth, and classed every quality-bearing bar by what the hint and the draft did. On the dense sheet at the bar grid, 25 of the 40 lost positions are bars where the hint's quality family was already wrong; the model followed the hint on fourteen and wrote a third family on eleven. Thirteen are power chords on one take, and two are bars where the model lost a right hint. The chord model's vocabulary has no half-diminished, so every such bar arrives with a wrong or empty hint.

The Clause

The production system prompt tells the model to think like a rock musician reading a chart, prefer simple progressions over exotic spellings, and expect power chords and sus chords. The variant replaces that clause with an instruction to name the quality the notes support, a seventh when the seventh sounds, a plain triad when it does not, and a power chord only when neither third sounds, and is pinned by test to differ from production in nothing else. Both the guitar takes and the ten modern songs were drafted under it on the shipped tracker's bars, the modern songs as the guard against a clause that helps a jazz sheet and hurts a rock chart.

What Moved

On the ten paired guitar takes, qualities rose on six and fell on one, roots fell on none, and the one confidently wrong draft on Beat This small's bars became good with its half-diminished named. Across all twelve takes five drafts are good under the clause against three of the ten production drafts that answered, and the half-diminished is spelled in seven of twelve where production spelled it in three of ten. Power chords did not retreat: five drafts carry one against three before, the two thin takes among them. The modern songs changed in nothing that matters: one quality count up by one, one root count down by two with the class unchanged, eight good drafts before and after.

Decision and Disclosures

The registered rule required qualities up on six takes and two more good drafts; good rose by one, so the registered outcome is a report without a recommendation, and the runner's own summary line, which used a looser condition and printed a recommendation, is corrected in the brief. The bench's labelled judgment favours the clause on the evidence and names the chord model's missing half-diminished as the larger remaining gap. Two guitar takes whose production drafts had stopped at the gateway's content filter drafted normally under the new clause; the bench records that and draws no causal line from two cases. Spend was $1.46 against a $2.50 fence; predictions P1, P3 and P4 right, P2 and P5 wrong.
