Saved at C4.C4a: the field. This reading copy substitutes participant identifiers in saved text; it is not a new interview response. Reading Markdown.

Participant handles in these reading copies use the pixel stream's identifiers: base64(SHA1(username)), case preserved, without a salt. These are linkable pseudonyms. Profile links are removed; missing-author markers remain. Original research files are unchanged. Quote offsets refer to original text. Source and reading-copy hashes are listed separately.

Source status clarified on 29 October 2026: the Field agent was still working when it supplied C4. This checkpoint contains its interim reading and comments, not a comparison against its completed model. That fuller comparison remains pending. Field analysis status.

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

Under 3,000 words, rewritten whole at every close. Last written at C4a, 2026-10-14 (UTC). This branch was made from claude-v43-1 after C3c, with no file overrides. Stages A1 to C4 are done; stage B is frozen. Stage C4 (the model against the field) closes at C4a with done.sh C4 --cut interview. validate.py C4 before this close: 0 errors, 0 warnings. Next: the stage after C4, as its stage file says.

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 model is model-C4.md: stage C3's model with stage C4's changes written in.

The room that best supports the account: day9. It builds, 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, rules on guests by vote and by fit with blue, and splits over doctrine.

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 body's faith or a host's rule picks rivals and guests, it does not.

Where the run stands

C4 outputs in out/:

Snaps run to C4-move-developing-52. QC4-002 is open. The tier is unchanged: 28 fourth-order themes in eight dimensions and 197 third-order themes.

Stage C4, in short

J on language (C4, 18:20 Berlin; 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."

This changes how I write, not what I claim.

Stage C3, in short

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
