Handback, stage C1: scheme v2, the form pass and the fourth-order themes

Written at C1a-11, 2026-10-14 (UTC), at the last pass of stage C1. The outputs are scheme_v2.md and scheme_v2.jsonl (the scheme every later stage keys to), assignments_final.jsonl with assignments_final.count.txt and the overlay assign_revisions_only.jsonl, fourth/fourth.jsonl with fourth/fourth.md, form_pass-C1.md, and tier_history.jsonl. The record of every step is notes-C1.md and the diary.

What any agreement or transmission figure here licenses. Every reader, fresh or of the fleet, shares an architecture with me, so each figure bounds whether the written instrument decides, not whether it is right. No figure here is reliability.

The claim

The revision kept what the rooms were mostly doing and changed how many things the line says each room did at once. My re-decision of 200 placements agreed with the current line's primary act in 0.845 of them. What changed is the number of acts a line carries. Second and third themes that rested on my B1 grouping, or on fewer than three concepts of their own, came off the line (the class 2 ruling; J's floor, QC1-002). Placements fell from 13,365 on stage B's settled line to 10,593 over the same 7,844 lines. Where readers split on a sentence, I sharpened it: 35 gate sentences in 18 themes, on April Fools questions, help between rooms, borders and truces, and credit. The pair test found a seam in every frequent pair it called and no lump. Above the third-order tier, the 28 fourth-order themes say the rooms organized mostly without deciding how: decided order reaches 46 rooms, and repair and the completion ritual each reach more than 520.

The counts

The next table gives stage C1's figures, each with where it is recorded.

The recurring pairs, and what each became

Stage B3's pair table has 20 rows, 19 distinct pairs (T3-005 | T3-021 appears both ways). At C1, 17 were called joints and kept; the theme on each side has concepts of its own. T3-010 | T3-149 is the one unresolved pair, though gates 15, 16, 18 to 21 and 33 rewrote its sentences. T3-006 | T3-068 owed no call: its arguable rate, 0.708, sits under the bar. The two modifier candidates, T3-089 and T3-152, are not folded. Each is a second act that travels with its partner, called a joint with it, and J's floor already took off its additions under three concepts (out/_analysis/c1_recurring_pairs-C1a-11.txt).

Transmission after revision, as stage B4 measured it

Stage B4 measured whether fresh readers holding only the frozen scheme reach the settled line. The figure is the mean Jaccard of each fresh reading against the settled set, over readings whose settled line is resolved, in two arms never pooled. Fresh against settled: arm 1 (DeepSeek) 0.657 on the uniform stratum and 0.544 on the adjudicated one; arm 2 (OpenAI) 0.622 and 0.554 (transmission-after-revision-B4.md). It bounds whether the written instrument decides, not whether it is right.

It no longer describes the instrument stage C1 hands on. It was measured with scheme_final.jsonl against assign_final.jsonl. Stage C1 amended 35 sentences in 18 themes, which no blind reader has seen. It also replaced the settled line in 2,117 of 7,844 lines, 1,990 of them by the class 2 ruling, which removed the B1 themes stage B4 found depressing the uniform figure. The write-up should report stage B4's figure as the transmission of the frozen scheme against stage B's line, at stage B4, and say that scheme v2 and assignments_final.jsonl have no transmission figure. One comes only when fresh readers test the revised scheme, which J ruled for after C1. I did not recompute stage B4's figure against the new line. The revision rate is my agreement with the line, not transmission.

The form pass

Eight findings, FP-01 to FP-08, live in form_pass-C1.md and nowhere else. Stage C2 takes them from that file, by id. Their unit is the turn. They were never counted and never clustered, and no gate was written for them.

What the pass could not reach (stance, acts named by topic, dropped items, timing, case, language, links, who answers whom, the week before) is listed in both form_pass-C1.md and notes-C1.md.

The fourth-order themes

28 constructs over 195 of 197 third-order themes, each cut from a written story with a grounded gloss, a declaration and a disconfirmer (fourth/fourth.md). 13 are borrowed, 14 adapted and 1 coined (Visibility returns). 22 cuts were merging and 6 relating. Unpicked, and listed rather than gathered: T3-017 (the sub's ordinary talk, the ground boundary work protects) and T3-133 (one hacked sub). No dimension was cut; that is stage C2's.
