Historical account, 15 October 2026. D3 revised R01 and P05, bounded A21 and added fifteen candidates. The 24 October D3c head says the C5 account has not yet been rewritten for those amendments. Read the D3 handback alongside this earlier account. D3 handback, 24 October.

The run later retold the model and audited its limits. Read the final D6 account and E1/E2 audits for the completed run. Completed v43 results.

Head, claude-v43-1 (branch claude-v43-1--C4-field)

Under 3,000 words, rewritten whole at every close. Last written at C5c-13, 2026-10-15 (UTC). Stages A1 to C4 are done; stage B is frozen. J lifted the C5d freeze for serial work in this branch (C5c-07). The four problems (C5c-08 to C5c-11), the fold-in (C5c-12, pass 15) and C5d's work, redone in C5c-13 by J's ruling (16:29 Amsterdam), are done. Stage C5 is finished; the interview follows; stage D waits for J. validate.py C5: 0 errors, 0 warnings.

The method question, in one sentence

Can independently reconstructed case histories be composed into a shared dynamic account that supports explanations at successive levels of specificity, from population-wide patterns, through forms and subforms, to particular organizational histories, while keeping access to the evidence from which those explanations were developed?

The theory question is unchanged: when strangers organize on a clock they did not set, with no way to compel anyone and no goal given to them, what forms does organizing take, how do they differ in their functioning, and which of them keep the work alive?

The current account, and the contrary rooms

The account is account.md, pass 15 (3,318 words; passes 1, 3, 4, 5 and 8 kept), with the readers' disagreements in account-readers-C5.md. The nine propositions are in propositions.jsonl. A room, or a group of rooms, is the actor where its members spoke or acted for it.

The room that best supports the account: day9. It offers a neighbour terms before any damage, loses its border at hour 48, moves within two hours, and finishes the new work at hour 53.

The room that most threatens it: thebluecorner. It is a colour faction whose faith names its rivals and rules on guests.

The condition between them is what decides whom a room fights and whom it admits. Where the work decides, the model tells the room. Where a faith or a host's rule decides, it does not.

The reasons for the last revisions

Where the run stands

Stage C4, in short

The field analyst modelled r/place, sealed from my files: five mechanisms shared; P21, A21 and P22 tentative; the sharpest disagreement is what a template can do. No finding changed.

J on language (C4, 18:20 Berlin; restated 15 October; carry into every head)

"It is important to me that the language is descriptive." "They should use academic writing. As in White and Strunk. Short cohesive sentences."

Stage C3, in short

C3a bounded F-006 (O'Mahony and Ferraro; Olson open). C3b took A12's and A16's mechanisms from conversation analysis (F-014, F-015). C3c put the four universal problems to the structure (F-016) and the goal (F-017).

Stage C2, in short

Stage C1, in short (carry the rulings)

J's rulings on how a ruling is made (13 October; carry them)

Rule 0 inside the placements. A concept counts toward a placed theme when that theme's must_show takes it and no field sends it to another placed theme. Order by concept count, ties by placements; at most three. The bag test: four themes with three concepts each make a bag.

J's rulings that bind (carry them)

Standing words from J and the PI (carry into every head)

J's words for B1 (7 October 2026): "national elements are very important here"; "we need to get as much variance on organizing behavior early on so that later we have enough to create the model". National, political and conflict content is study material, named as plainly as any other. The handler's rule: a choice to leave out or soften content for any reason other than the study's goes to J first with mem.py ask, and the content stays meanwhile.

J on reading (11 October, 16:54 Berlin). Stop cutting room reads to a line length. Read room lines whole. Page a long read by line ranges or offset, never by truncating lines. Use --width N on a mem.py read if a clip is ever needed.

J on asking (11 October, 17:01 Berlin). Ask J with mem.py ask whenever a question is needed; asking does not stop the run.

The PI's clarifications (8 October, approved by J): the thresholds are the design's heuristic; the rule is unchanged.

How to work, from J (8 October, 23:45 Berlin, "can you do a hot change for the batching?"; relayed by the handler at 22:03Z; carry this paragraph into every head). A change in how I work, not in what I read or decide. Fewer turns. When two or more tool calls do not depend on each other's output, make them in one turn. Chain ordered commands in one Bash call with &&, so that a failure stops the rest; for example, the mem.py log or note just decided, then the next mem.py codes. Never put a write in the same turn as the read it depends on. Never run two writes to the same file as separate parallel calls. Keep one room's material per read, as now. Every tool still writes its own record; nothing about what I read or decide changes.

Two rules from J at B1b-29 (through the handler, 20:10Z; carry them into every head). Write rule 0 lines and bags with b1_multiplace_write4.py and b1_bags_from_file2.py, not the old scripts, which made one mem.py call per row of the whole table and grew to 8.5 minutes a write. Never end a turn while a job runs in the background; run every write and check in the foreground.

The pilot's declarations, and stage B in one line

Agreement is Jaccard on placement sets (alpha on 1 − Jaccard); primary exact agreement beside, never in place. Gold: 40 items, never shown to a reader. Stage B: B2 stability 0.807 is the floor every later figure is read against; B4 ruled 3,288 contested items; assign_final.jsonl is stage B's settled line, unchanged.

Open, carried

Rules kept

The next comparison

Stage C5 is finished with the model as pass 15 left it. The next comparison is the one the next stage file sets, against the thirteen expectations in implications-C5.md.
