Head, claude-v43-1

Under 3,000 words, rewritten whole at every close. Last written at C2d-02, 2026-10-14 (UTC). Stages A1 to C2 are done; stage B is frozen. Stage C2 (the model: the loop) ran five passes and closes here, at the last closing pass. The model rests on pass 5. validate.py C2 before the close: 0 errors, 1 warning (the rise in told-with-residue at pass 4). Next: stage C3, as the next launch 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 rests on pass 5 (model-p5.md, model/story-p5.md). A member starts a mark, calls gather hands, the hands build, and keeping the mark becomes the work. The calls fill the host sub, and the sub draws a line around them: one thread, removals, a canvas sub, members objecting to the flood. Keeping the mark brings the room up against neighbours: it talks with them, settles borders, trades help, and joins coalitions under attack. A call can also turn hands against a rival's work; most such calls are answered inside the room by refusal, restraint or a truce. A room that judges it cannot hold its spot moves, and keeps calling. The close runs in order: celebrated, recorded, carried on. Placement ends at hour 73. In some rooms a tie the members had before the canvas (a league or school rivalry, a nation's history, an ideology, lore) names the rival in the same turn as the attack: a claim in the rooms' words, untested for order. Two forms are boundaries at the return: colour factions the canvas gathered, and hosts ruling on guests.

The room that best supports the account is day9, a within-case room, told at passes 2 to 5: 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 is thebluecorner, a colour faction whose faith names its rivals, rules on guests by vote and by fit with blue, and splits over art on a blue backdrop against a pure blue corner; greenlattice, purplecorner and orderofthebluecorner show the same. 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 tie from before the canvas names the rival in the attack turn, the claim tells it. Where a body's faith or a host's rule picks rivals and guests, the model does not reach it.

Where the run stands

C2 outputs in out/: dimensions.jsonl (eight); fourth/fourth.jsonl (28, 21 in the model); structure.md, structure-p2.md, structure-p4.md; concept.md (pass 5 section added); within_case.md; model/elements.jsonl (28, three candidates), model/arrows.jsonl (20), model/loops.jsonl (empty), model/history.jsonl (82); model.md, model-p2.md to model-p5.md; model/story-p1.md to model/story-p5.md; story_rooms-p1.jsonl to story_rooms-p5.jsonl; saturation.jsonl (five lines); findings.jsonl (20 lines, 13 findings); tier_history.jsonl (476); notes-C2.md; handback-C2.md. The reviewer's files: RETURN-C2.md, review-C2.md, its packet and manifest entry. Snaps run to C2-move-developing-47. No question is open.

Stage C2, pass 5 (C2d-02), in short

Stage C2, passes 1 to 4, in short

Pass 1 (C2a-01). J, away, ruled at 23:24 Berlin: "If I am not back please simply review and make the interview you find appropriate. Then start C2", and "Remember Gioia Corley Hamilton and the job the agent has. Remember we need to give it confidence so they can gain intuition and trust on the model." The handler answers questions under J's delegation of 23:26 Berlin. The connection statement: "the first concept of FROM comes before the first concept of TO", with a null of 500 shuffles within each room (seed 20261014). 20 elements, 12 arrows. All twenty story rooms told with residue.

Pass 2. Exchange between rooms, the contest carried on in talk, coalitions; Contention split as an eighth dimension. Told 14, told-with-residue 18.

Pass 3. The host's line added; the idiom rule set during the reading. Told 16, told-with-residue 16. Pass 3 went to the reviewer.

The reviewer (C2b, C2c). QC2-001 (the handler, under J's delegation): serving sections of the pass 3 model file is acceptable; errors are read against the whole file (sha256 aa75ee6c…). One return on Opus: nine errors, six accepted in full, two in part, one refused; a partition at adjusted Rand 0.661, firm where the model has arrows and loose where the residues are.

Pass 4 (C2d-01). Two recuts by rules written first (hosting to Territoriality; the flag and emblems to Collective representation). Eight declared tests, three beat the null. Membership then attack, narrowed, fell below the null mean (52 of 126). The instance audit: 48 transitions, 34 pass, 14 fail, none swapped. Told 11, told-with-residue 21.

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.
