# Room form A, the terms between neighbours, with the plan announced: the form account

Written at D5a-36, 26 October 2026. The model is the version frozen at D3 (46384686d6173fdeb4c749667478c1363e675bc6b52bb6f4fdc211d387e68525). Form A is one of the six room forms of the cut J ruled at D4a-08 (`room-forms-D4a08c.*`); how every room reaches its form is in `room-forms-allocation.md`. It holds 166 of the 705 analysed rooms. 135 are defining rooms: rooms with 5 or more selected changes, which shaped the form. 28 are thin rooms (1 to 4 selected changes) and 3 are core rooms (no selected change), placed afterwards. Thin and core rooms weigh less: every share, signature, theme count, representative choice and split below is read on the 135 defining rooms, and the thin and core rooms are named in section 15.

A room form is not a branch. A branch of stage D4 gathers the rooms that share one change key. A room form gathers rooms by the whole mix of their changes (two thirds) and their codes (one third), so the 35 branches are the level below it (section 12). The form is a pole of a continuum, not a kind: 35 of its 135 defining rooms lie nearer another form's centre (section 13). This file sits beside the room-forms files, not in `forms/`, because the stage's close-check reads every account in `forms/` as a branch account (`departures.jsonl` line 18). Hours are counted from the start of the event (h+).

## 1. How these rooms organized, as a narrative

In these 166 subreddits the room built beside other rooms' work and settled with its neighbours what each could have. The settling came early. Often it came while the room was still building, before it had anything to keep.

Members warned the neighbour before they built over its work. In r/cavestory a member wrote, "we should tell /r/tampabaylightning about balrog because we're going to end up running over their logo" [cavestory/c0032]. Another agreed to a plan "as long as r/ainbowroad gets word of the project." [cavestory/c0021]. Neighbours came to them as well. A r/stardewvalley thread received a visitor: "Hey, I'm from the HotS team and your chicken is touching our border." [stardewvalley/c0074]. A member answered, "I'm sure we don't mind the bum of our chicken getting cut off a little bit if it can work with your border." [stardewvalley/c0075]. The visitor replied, "I think we can figure something out. I think it looks nice enough." [stardewvalley/c0076].

The rooms decided what they could give. In r/placetardis a member drew the line between the picture and its frame: "The black border and blue background isn't "content"" [placetardis/c0013]. The room let a neighbour expand into its background: "They've agreed not to go over the actual TARDIS, but it seems silly to not let them go into our blank blue background. Please let them do their thing." [placetardis/c0028]. Size entered the terms. A neighbour asked r/redhotchilipeppers to move, taking it for the bigger sub. A member answered, "we only have 3 people working on this so it will be difficult" [redhotchilipeppers/c0065], and the neighbour gave way: "My group said it's fine then." [redhotchilipeppers/c0066]. In r/israel's thread an artist who could not win gave pixels instead: "Fair. I could not win anyway, I would just be a thorn in your side. So, I will devote pixels to help you in hope that I receive help." [israel/c0061].

A few members made a deal, and the rest of the placers had to learn it. A r/poland member reported a peace: "we won't bother each other, but it will take some time for everyone to get the news" [poland/c0039]. In r/ManningPlace a member admitted that "there might be some who haven't gotten the memo." [ManningPlace/c0055]. In r/clg a neighbour's member wrote, "it seems we still have uninformed broncos fans going on your border. I'm messaging them individually about our truce" [clg/c0067]. Some placers were out of reach. "There is compromise with most of the swedes on discord but not the rouge ones." [stardewvalley/c0086]. In r/FloydVsVoid a member answered a neighbour's complaint: "many of our contributors arent on our sub or discord and thusly arent under our direct control" [FloydVsVoid/c0128].

Restraint often came before any deal. A r/oneshot member asked the room to wait: "until we receive word from them, please do not damage it." [oneshot/c0025]. Members apologised when they learned what they had covered. "Yay! My apologies to /r/Cornwall - I didn't realise!" [Dorset/c0006]. "Sorry, that was my bad. I didn't know the black border was important. Sorry again!" [stardewvalley/c0090].

The room's own plan met the same problem. A change had to reach the members who placed and repaired. A r/monalisaclan member wrote, "I was trying to help out but because I didn't know there was a newer design I was messing it up. please delete the posts or put a warning on them and link to the new design." [monalisaclan/c0105]. In r/philippines a placer was scolded for one pixel: "Damn there should be a pinned post about r/place plans. Somebody PMed me for putting 1 red pixel on it." [philippines/c0449]. A r/FloydVsVoid member corrected the room's own instructions: "That's still the wrong plan in the main post. Here's the new one" [FloydVsVoid/c0153].

Not every term held. A neighbour offered r/FloydVsVoid a truce on hard terms: "Truce and you help me get my letters over your prism" [FloydVsVoid/c0089]. The room refused: "The prism with a copypasta on top is not an option, we'll have to find another way" [FloydVsVoid/c0202]. The neighbour answered, "Then I will be removing your prism, sorry. I was offering you a way to keep it." [FloydVsVoid/c0203].

The rooms marked the work as it went, and then went back to keeping it. A r/stardewvalley member thanked the room: "It only took about a day, and three moves, but in the end it was worth it to see our little guy on that canvas." [stardewvalley/c0098]. The next reply turned to defence: "Yay! So proud of our team work! Lets do our best to defend the little guy." [stardewvalley/c0099].

## 2. What the form does

These elements are instantiated in 80 per cent of the defining members or more (`_analysis/d5f_model.py`, current ledger, particular lines included). The model's prose says them so.

- P01 (135 of 135; 100 per cent of the 558): "The room calls its own members, and kindred subs, to come and place for a work: to start it, build it, finish it or hold it."
- P02 (135 of 135; 100 per cent of the 558): "The room settles what its mark will show of it: a member proposes a picture, the room argues its design, makes its land's flag or emblems the mark, signs it or leaves it unsigned, claims a mark others made, adds to it or enlarges it, or adds a personal piece to a shared mark."
- P03 (132 of 135; 97 per cent of the 558): "The room builds its mark, and members report its state to the thread: what is placed, done or missing, and where."
- P05 (132 of 135; 93 per cent of the 558): "The room keeps its placed work against erosion: members watch it and repair changed pixels, and the room rallies to defend it under attack, covers the night, hardens its shape and puts upkeep before growth. Repair restores the form the keepers know. A change the room has planned or agreed (P02) is therefore repaired away as damage until its keepers are told of it, and it is lost or given up where the telling does not reach them."
- P11 (131 of 135; 96 per cent of the 558): "When a work is up, the room marks it: announces it, celebrates it, credits makers and helpers, reports members' own parts and says what working with strangers meant."
- P12 (131 of 135; 97 per cent of the 558): "The room records what happened to its work and to the canvas around it: screenshots and timelapses, reports of its fate, mourning, imagined art, atlas entries, the end marked."
- P04 (130 of 135; 97 per cent of the 558): "Members circulate a template that lays out the mark pixel by pixel, or coordinates that locate it, ask for them, and ask strays to keep to them."
- R01 (128 of 135; 96 per cent of the 558): "The starter: a member who proposes the mark, maps it or begins placing it. Others joining is not part of the role: it is the answer to the room's call (P15), in the order A02 and A01 state."
- P07 (127 of 135; 89 per cent of the 558): "Rooms spare their neighbours' work, rein in their own attackers, apologise for damage and appeal to attackers to stop."
- P08 (127 of 135; 86 per cent of the 558): "Rooms propose, settle and contest borders, truces and deals with neighbours by talk, through envoys, and hold each other to them."
- P15 (127 of 135; 91 per cent of the 558): "A member answers a call or proposal in one line that joins, assents, reports a part done or thanks, and the line asks for nothing back."
- P16 (126 of 135; 91 per cent of the 558): "Rooms help one another's works and trade help: they give pixels to a neighbour's mark, ask other rooms for help, barter help for space or repair, thank their allies, greet them, and turn requests away."
- P06 (120 of 135; 87 per cent of the 558): "Members work out who changed their work and why: they trace placers and rooms, find friendly fire or their own mistake, blame officers, or disown placers acting in their name."
- K02 (114 of 135; 82 per cent of the 558): "The room judges that it has too few hands or too little room for the work it wants: doubt, a canvas judged too full, a work judged absent or outclassed."
- P24 (114 of 135; 89 per cent of the 558): "Members ask what the canvas is, how to place, what a call or a name means and what a picture shows, and others explain the rule, the timer, the controls, whose mark a picture is and what happened. They ask before, during and after the close, and some questions get no answer."
- R02 (113 of 135; 81 per cent of the 558): "The envoy: a member who acts for a room toward another room, carrying a proposal between threads or chats."

The model takes a room from building to keeping (A03), from keeping to talk with its neighbours (A04), and from a settled border to sparing (A05) and to traded help (A14). These rooms do all of it. They do the talk with neighbours more than other rooms do. P08, the borders, truces and deals, is instantiated in 127 of 135 defining members, against 86 per cent of the 558 defining rooms. P21, members stating the limits of who may commit the room to an agreement, is instantiated in 45 of 135 (33 per cent), against 24 per cent.

## 3. What it does differently, element by element and arrow by arrow

**The change signature.** The form's defining members change three fourth-order themes more than the defining population does (at 1.5 times its share or more, in a third of the members or more). Negotiated order is changed by 86.7 per cent of them, against 58.1 per cent of the 558 (share ratio 1.75). Completion ritual is changed by 51.1 per cent, against 37.6 (ratio 1.58). Standardization of output is changed by 37.0 per cent, against 18.8 (ratio 2.06). These come from the allocation's columns (`room-forms-D4a08c.jsonl`).

**Element by element and arrow by arrow.** The table gives every element or arrow and op that 14 defining members or more change, at 1.2 times the defining population's share or more (`_analysis/d5f_facts.py`). A selected line specifies the model (add-condition, add-step), restricts it (restrict), connects two of its parts (link) or contradicts it. The kind of a line is not relied on (J: kappa 0.08).

| element or arrow | op | defining members with a line | share | share among the 558 | ratio |
|---|---|---|---|---|---|
| A14 | restrict | 15 | 0.111 | 0.065 | 1.72 |
| P11 | add-step | 21 | 0.156 | 0.106 | 1.47 |
| P05 | add-condition | 37 | 0.274 | 0.192 | 1.43 |
| P08 | add-condition | 14 | 0.104 | 0.073 | 1.41 |
| P08 | link | 16 | 0.119 | 0.084 | 1.41 |
| A05 | restrict | 39 | 0.289 | 0.215 | 1.34 |
| P05 | link | 27 | 0.200 | 0.152 | 1.31 |
| P12 | add-step | 16 | 0.119 | 0.091 | 1.30 |
| C01 | restrict | 17 | 0.126 | 0.099 | 1.28 |
| P08 | add-step | 21 | 0.156 | 0.122 | 1.28 |
| P04 | add-step | 32 | 0.237 | 0.188 | 1.26 |
| P23 | add-step | 16 | 0.119 | 0.097 | 1.22 |
| P14 | restrict | 17 | 0.126 | 0.104 | 1.21 |
| P07 | add-condition | 16 | 0.119 | 0.099 | 1.20 |

No defining member holds a contradict line, so these rooms replace nothing in the model. They specify it, restrict it and connect its parts. I read the lines behind the table whole (`_analysis/d5f_dump.py`: 98 lines on the negotiated order, 70 on keeping, 73 on the plan and the marking).

- **P08, borders, truces and deals: specified (add-step 21 members, add-condition 14) and connected (link 16).** The added steps are the work of making terms. Members warn a neighbour before building over its work, discuss a border inside the room before contacting the neighbour, decide which pixels can be ceded, find the channel through which to reach the other room, and carry the news of an agreement past the venue where it was made. r/placetardis: "Members distinguished expendable background and border pixels from recognizable picture content when deciding what space could be ceded." r/poland: "Agreement news must be transmitted beyond its negotiating venue, and participants explicitly describe that transmission as still incomplete." The added conditions say whom an agreement binds. r/bostonbruins: "An agreement's effective reach depends on placers knowing and accepting its plan, because uninformed numbers can overwhelm negotiated coexistence." The links put the talk inside the building. r/cowchop: "Anticipated collision during construction provides a stated reason for overlap negotiation before the core image is secured."
- **P07, sparing: specified (add-step 12 members, add-condition 16).** Restraint is offered before any agreement settles the overlap, and it is selective. r/oneshot: "Restraint also operates while permission is pending, preserving neighbouring work before an agreement settles the overlap." r/hsv: "Appeals to spare the room can redirect destruction elsewhere, making restraint selective rather than protection of every neighbour."
- **P05, keeping: specified (add-condition 37 members) and connected (link 27).** Two things recur in the conditions. Keeping can mean undoing one's own pixels to spare a neighbour. r/opticgaming: "Explains cooperative upkeep that permits removing one's own bricks when preserving them would destroy neighbouring art." And the telling clause of P05 (a planned change is repaired away until the keepers are told) works from the other side as well: told keepers can refuse. r/de: "Telling keepers about a planned change does not secure acceptance when they knowingly reject it as a takeover." The links send the marking back to keeping. r/japan: "A completion announcement explicitly requires continued protection, adding a feedback from accomplishment to maintenance."
- **A05, from a settled border to sparing: restricted (39 members) and specified (add-condition 15).** Section 7 reads the restrictions. The added conditions say that an agreement spares a neighbour only where its terms reach the placers and their scripts. r/ManningPlace: "A border decision guides coordinated restraint only where its terms reach placers, since some reportedly have not gotten the memo." r/TheFarLeftSide: "An agreement must reach human keepers and bot targets before it can reliably become their restraint rather than another construction they erase."
- **A14, from border talk to traded help: restricted (15 members, 1.72 times the defining population's share).** Help came before the terms, or the record shows an offer and not the help given (section 7).
- **P04, P11 and P12, the plan and its marking: specified (add-step 32, 21 and 16 members).** The plan is kept current and announced, so that keepers do not undo a change. r/monalisaclan: "Helpers request warnings on obsolete templates and links to current designs so intended repair does not undo the plan." r/philippines: "Members propose pinned plans, direct messages and recognizable outlines to inform cleaners before they undo new work." The work is marked while it goes on. r/anime: "Credit is actively checked and corrected during ongoing work rather than appearing only at the close."

**What a room of this form does that the model would not predict.** The model has every element these rooms use, and the arrows' bounds already allow talk with neighbours, and sparing, to come first (A04 and A05; section 7). What the model does not say is what making terms takes, and whom terms bind. A room of this form makes terms while it builds, before it has a mark to keep. It finds out that an agreement, and its own plan, bind only the placers and scripts they reach. And it works to reach them: it messages placers, posts warnings, updates templates and retires stale calls. In the lines I read, 29 defining members state that terms or a plan hold only where they reach the placers. They are listed with their lines in `_analysis/d5a36_reach_rooms.txt` and counted by script; the list is a reading, not a ledger count. That is a fifth of the members, so it is a pattern inside the form, not the form.

The rooms that show this best are r/FloydVsVoid and r/stardewvalley, and the one that shows it least well is r/futanari (section 11, by the rule stated there).

**What the claim rests on.** The form is a cut of the allocation (changes two thirds, codes one third, Ward's method, six forms by J's ruling). It is validated only as far as that cut is: its stability on matched subsamples is about 0.21, and 35 of its defining rooms lie nearer another form's centre. The table's counts are the ledger's. That members made terms while building and told placers of them is a claim on their words, through `cite.py`, in sections 1, 4 and 11. One kind of evidence does not stand in for the other.

**The name, read against the members.** The name is "the terms between neighbours, with the plan announced". The strongest argument that it names the cut rather than what the rooms did: it joins the names of two of the eight forms of D4a-08b (the terms between neighbours, and the plan made and announced), merged at seven. A reader who suspected the name would look for members with no terms in their record, and for the plan held apart from the terms. The first exist: r/futanari's record shows a piece shown, praised and captured, and nothing between neighbours (section 11). The second does not: the part that leans to the plan still holds the negotiated order in 82 per cent of its defining members (section 14). The members support the name. I make no renaming proposal. One candidate reading, terms and plans that hold only where they reach the placers, goes to `notes-D5.md` for D6, as a pattern of a fifth of the members.

## 4. The concepts it employs

First-order concepts for each change the form leans to, through `cite.py`:

- **Terms made while building.** "Is it possible to move the carrots below us to another spot, to make room for Balrog?" [cavestory/c0034]. A neighbour opens the talk: "yall are kinda interfering with the raps logo.wanna talk abt it?" [vermont/c0022].
- **What may be ceded.** "The black border and blue background isn't "content", and if people ask to take our background or border for actual content, I'm all for it." [placetardis/c0013].
- **Terms that must reach the placers.** "We are putting up an announcement on the main page but if you guys can message them about our truce because they've missed it somehow" [clg/c0068]. "Contact r/ainbowroad to get them to put this on their official live thread." [drawhelix/c0024].
- **Restraint before a deal.** "until we receive word from them, please do not damage it." [oneshot/c0025], then "Update: we have been given the go-ahead to finish the sprite and outline where it touches the rainbow." [oneshot/c0026].
- **Keeping that spares the neighbour.** "I'm having to defend ireland's flag from people extending the rainbow too far!" [FloydVsVoid/c0140].
- **The plan kept current.** "Mods, can you PLEASE update the official design?" [monalisaclan/c0141]. "Revised plan for the Mona Lisa (please take note of new changes thnx guys)" [monalisaclan/c0196].
- **The marking during the work, and back to keeping.** "I'm so damn proud of you all!" [FloydVsVoid/c0151]. "Yay! So proud of our team work! Lets do our best to defend the little guy." [stardewvalley/c0099].

## 5. Composition here

Three judgments are kept apart.

**The original global model (historical).** `verdicts-D.jsonl`, by the last analyst ruling or else the readers' agreement. All 166 members: composes 74, composes with residue 90, does not compose 0, cannot tell 2. The 135 defining members: composes 59, composes with residue 76, does not compose 0, cannot tell 0. The two that cannot tell are core rooms, r/Lugarix and r/yerbamate, with 5 and 1 coded concepts. These verdicts describe the unadapted model at the first return.

**The adapted local accounts.** By `adaptation-returns.jsonl` and the current model hash (46384686), as `vlib.local_return_states` reads them, all 166 members are unresolved; none is validated and none has insufficient evidence. The limit D3 named is the same for each: the labelers marked every local account unresolved, and prior.md section 3's measure of local validation was not computed (J after the D3c interview). The unresolved members are:

r/2007scape, r/AcePlace, r/adventuretime, r/ainbowroad, r/animalcrossing, r/anime, r/asexuality, r/auburn, r/batman, r/berserk, r/bostonbruins, r/buffalobills, r/carletonu, r/catalunya, r/cavestory, r/CelticFc, r/ChronoTrigger, r/cirkeltrek, r/clg, r/compsoc, r/Cornwall, r/cowchop, r/croatia, r/DCFU, r/de, r/detroitredwings, r/DevonUK, r/Dorset, r/drawhelix, r/Dustforce, r/edboxes, r/empiredidnothingwrong, r/epublica, r/evedreddit, r/faeria, r/finland, r/fireemblem, r/FloydVsVoid, r/forsen, r/foxes, r/ftlgame, r/funhaus, r/furry, r/futanari, r/germany, r/ghibli, r/giantbomb, r/Goodboye, r/gravityfalls, r/greenlattice, r/halo, r/hatsune, r/hellointernet, r/heyyea, r/hsv, r/hungary, r/iceland, r/indonesia, r/ireland, r/israel, r/Jamaica, r/japan, r/jerma985, r/k_on, r/kamenrider, r/kcroyals, r/kilian, r/kurdistan, r/lakers, r/landry, r/lifeisstrange, r/littlewitchacademia, r/loliconsunite, r/lsu, r/luciomains, r/Lugarix, r/malaysia, r/mamamoo, r/ManningPlace, r/MiamiHurricanes, r/mindcrack, r/monalisaclan, r/MonkeyIsland, r/monsterhunter, r/Moondye7, r/mordhau, r/morrowind, r/mysterydungeon, r/necrodancer, r/neopets, r/neutralmilkhotel, r/norway, r/npr, r/nVade, r/Okami, r/onepunchman, r/oneshot, r/opticgaming, r/orderofthebluecorner, r/osugame, r/pansexual, r/parabola, r/paranatural, r/Peru, r/peterdraws, r/philippines, r/PinkUnion, r/placehearts, r/placeportalpattern, r/placetardis, r/poland, r/prequelmemes, r/rainbowgrid, r/raocow, r/ravens, r/ReBoot, r/redhotchilipeppers, r/redvsblue, r/RelientK, r/rhythmheaven, r/ripcity, r/riskofrain, r/rocketbeans, r/roosterteeth, r/seolhyun, r/seventeen, r/signal, r/sonicthehedgehog, r/sooners, r/soylent, r/stardewvalley, r/starryknights, r/starvstheforcesofevil, r/Summit1G, r/SwissNeutralityZone, r/switzerland, r/taiwan, r/TeamYellowPlace, r/telegram, r/texastech, r/thailand, r/TheB1G, r/theexpanse, r/TheFarLeftSide, r/TheHulk, r/tinytardis, r/toolband, r/transformers, r/TsundereSharks, r/twice, r/ubreddit, r/ucf, r/uiuc, r/utahjazz, r/utaustin, r/uva, r/VelvetUnderground, r/vermont, r/Villanova, r/vinesauce, r/vocaloid, r/winnipegjets, r/witcher, r/xcom, r/xenoblade_chronicles, r/yerbamate

**The shared form explanation: unresolved.** The form's members share a lean, not one change: 86.7 per cent of the defining members change the negotiated order, and their changes specify the model's own elements. Much of what they restrict, the arrows' bounds already state (section 7). And 35 of the 135 defining members lie nearer another form's centre. So the form describes these rooms jointly as a lean of the population. It does not yet explain them as one shared change would. Every member's own adapted account is unresolved as well. A verdict of composes with residue on the original model is not a current local or shared failure.

## 6. How the model runs here

Counts are of defining members with a current-ledger line, particular lines included (`_analysis/d5f_model.py`); they count any line of an op.

**The elements that do the work.** The elements of section 2, with P08 above the population's rate (94 per cent against 86) and P21 above it (33 per cent against 24).

**The elements that sit idle.** P34 is absent in 134 of 135 defining members, P30 in 120, P33 in 115, P28 and P29 in 106, C02 in 105, K03 in 104 and A21 in 103. They are idle in the population too (between 69 and 99 per cent), and their idleness does not mark the form.

**The elements that fit less here.** K01, the April Fools frame, is instantiated in 54 of 135 (40 per cent), against 57 per cent of the 558. P20, the host's line, is instantiated in 50 (37 per cent), against 49 per cent. These rooms worked on the canvas between neighbours more than on their sub's play or its host's rules.

**What these rooms do that the model has no place for.** 37 of 135 defining members carry 47 propose lines, against 210 of the 558 defining rooms. The propose lines are not part of the form's lean.

**Where the room models and my reading disagree.** They agree. r/FloydVsVoid's model reads A04 "only at that local contact step rather than proving upkeep caused every alliance", and r/stardewvalley's model says that its neighbour's "we can figure something out" "remains prospective". My reading of the members' lines is the same: the terms are visible, and whether they were kept often is not.

**The held proposals (QD4-001; never served to any room, not re-checked).** The model above is the frozen version. J ruled that both held proposals are stated in full wherever the model is reported. They are, as the tree file states them:

- **P05, move 198 (contrasting), history lines 173 to 176, reverted by line 181 (move 203).** The statement would gain: "This holds where the keepers can learn of a planned change only by being told, and no informed member holds it." The status would be bounded. The bound would read: "It does not hold where the keepers read a planned change from its shape and stop repairing it with no telling: completeanarchy, polska, satania, halo, bangtan, thesilphroad (R-completeanarchy-c187508d7ae3-022, R-polska-dadda7358f9a-049, R-satania-84df196116f3-022, R-halo-b988854ba168-036, R-bangtan-7efe23da0d0c-070, R-thesilphroad-a3f86618e239-018), a candidate branch, 'the shape read' (F-024). It does not hold where informed members hold the change against keepers who do not know: armok, maryland, oneshot (R-armok-8852b2ab85f8-022, R-maryland-d1b6e2d1d5f3-017, R-oneshot-e840e127e9b2-013), a limit below the trigger, at three nodes.

Lines: R-completeanarchy-c187508d7ae3-022, R-polska-dadda7358f9a-049, R-satania-84df196116f3-022, R-halo-b988854ba168-036, R-bangtan-7efe23da0d0c-070, R-thesilphroad-a3f86618e239-018, R-armok-8852b2ab85f8-022, R-maryland-d1b6e2d1d5f3-017, R-oneshot-e840e127e9b2-013.
- **A11, move 199 (dropping working hypotheses), history lines 177 to 180, reverted by line 182 (move 203).** The arrow from P02 to P04 would be withdrawn (status withdrawn, in_model false). Its reason, as written: "Rule 16 and rule 14: preserve what remains supported, and replace or withdraw what does not. No defensible formulation of A11 as an arrow survives the return. (1) The order between rooms never beat its null (111 of 185 rooms, 0.600; null p95 0.670; base_rate_beaten false), and C2 withdrew it, keeping a transition inside threads. (2) Inside threads, the return's census (D3a-38, re-run as _analysis/d4a01_a11_classes.json) shows the transition in 111 rooms and template first in 98 of the 228 rooms whose lines show both ends; across threads 19 more. The reverse order is nearly as common, so the arrow carries no direction. (3) The failure clause is present and stands alone in 117 rooms: talk only in 31 (berkeley, bih, bitcoin, edboxes, eve, FinalFantasy, guatemala, habs, HomestarRunner, indieheads, ireland, latvia, leagueoflegends, mexico, morrowind, msu, parrots, placeDE, placesnek, polska, portugal, quebec, samuraijack, slovenia, spain, suomi, titanfall, torontoraptors, unitedkingdom, wine, zootopia) and layout only in 86. (4) The mechanism's word 'settled' is contradicted by 261 accepted restrict lines whose 'how' says a template does not settle the design for good (rival templates, polls, later redesigns, placers who deviate). A reworded arrow (a layout answers design talk in its thread) would be a new claim, never served to any room, with its reverse nearly as common: a co-occurrence, not an arrow. What remains supported, that design talk and layouts meet in threads, is held by P02's and P04's statements and ranges ('a design argued over days and redone'; 'an official template the room asks everyone to follow against other versions'), which stand. The arrow's record keeps its evidence and reasoning."

2 of form A's rooms are among the rooms of the P05 proposal (r/halo, r/oneshot). 3 are among the talk-only rooms of the A11 proposal's failure clause: r/edboxes, r/ireland, r/morrowind.

## 7. The restrict lines: the arrow fails here, or the record cannot show it

**The rule, logged before reading.** I read every restrict line on an arrow held by a defining member, 432 lines, and sorted each `how` sentence (`_analysis/d5f_restricts.py`; my sort in `d5a36_sort_1.json` to `d5a36_sort_6.json`, joined in `d5a36_restrict_sorted.json`). *The arrow fails here*: the line says the consequent came without the antecedent, from another source or in another order, or that the antecedent did not lead to it. *The record cannot show it*: the line says the order, the link or the step is not visible, not dated or not established in the record. *Both*, where it says both. *Neither*, where it states a condition or a scope, or says that the two acts coincide or overlap. This is one reader's sort, mine; no second coder read it (J: no readers for the rest of the run).

| arrow | from, to | lines | the arrow fails here | the record cannot show it | both | neither |
|---|---|---|---|---|---|---|
| A01 | P01, P03 | 20 | 6 | 12 | 2 | 0 |

**The form's own arrows: the arrow fails as stated, inside bounds the model already writes.** A04 runs from keeping to border talk. In 27 of its 35 restrict lines here the arrow fails: talk with the neighbour came while the room was building, from an overlap it expected, or before it had anything to keep. r/hsv: "Border negotiation can arise during building into occupied ground without defence of an established mark as its immediate cause." A04's own bound already says that rooms which came to a full canvas talk with neighbours first. So these lines restate the bound. They do not find a new failure. A05 runs from a settled border to sparing. In 17 of its 39 lines the arrow fails: restraint came before any agreement, from a norm or an apology. r/MonkeyIsland: "An agreement is unnecessary to explain this restraint because the speaker directly states avoiding conflicting portions." A05's bound already says that sparing often comes first and tacit. In 16 more the line states a scope: the agreement binds only the placers it reaches. r/placetardis: "Settlement produces restraint only when placers receive and recognize the agreement, as missed plans and stops after discovery demonstrate." That is what P21 holds, and it is instantiated here above the population's rate.

**The arrows every form restricts.** A10 (judging too few hands, then the move) fails here in 37 of 50 lines: the shortage led to recruiting, holding or resizing, and the moves had other causes. A11 (a template settles a design) fails in 38 of 61: the template did not settle the design. That is the ground of the held A11 proposal. A07 (a work up, then the marking) fails in 12 of 16: the rooms celebrated before the work was done. These rates are not this form's own; A10 and A11 are restricted at the population's rate here (section 3's table holds neither).

**Where the record cannot show it.** The record cannot show who joined because of a call (A01, 12 of 20 lines). It cannot show whether help arrived (A13, 17 of 30; A14, 9 of 15), or whether a script ran (A06, 12 of 25). It cannot show that a call turned members against a rival (A15, 10 of 13), or what every reader owed an answer (A12, 15 of 30). In these lines the coders saw an offer, a request or a call, and not what followed it.

**So the two readings divide by kind.** Where the line concerns the order of two acts the rooms report (talk and keeping, a border and sparing, a template and a design), it mostly says the arrow fails as stated. Where it concerns delivery or cause (help given, scripts run, members recruited), it mostly says the record cannot show it. Across all 432 lines: the arrow fails here in 201, the record cannot show it in 136, both in 34, neither in 61.

## 8. The one relationship that runs differently here

A04 runs from P05 (keeping) to P08 (borders, truces and deals). Its connection: "in a room carrying both, the first act of upkeep or defence comes before the first border talk, truce or deal". Its mechanism: "Keeping a mark against erosion brings the room up against the neighbours whose pixels erode it, and the room turns to talk with them."

In r/stardewvalley it runs as stated. A defender asked for help at h+34.22: "the Junimo is getting rekt I don't think I can do this alone. EDIT2: I really need some help here." [stardewvalley/c0024]. At h+49.38 the same member reported terms: "I just made a deal with /r/luciomains and they've agreed to build around the Junimo but there is still random people trying to destroy it." [stardewvalley/c0025].

In r/cavestory it runs the other way. At h+43.74 a member proposed talk before the room built over a neighbour: "we should tell /r/tampabaylightning about balrog because we're going to end up running over their logo" [cavestory/c0032]. In r/redhotchilipeppers the terms came before the room had a secure mark: "we only have 3 people working on this so it will be difficult" [redhotchilipeppers/c0065]. The coders' line: "Disclosing few active builders changes a neighbour's answer from requesting movement to accepting the location."

In 35 of 135 defining members a current-ledger line restricts A04, against 22.9 per cent of the 558. A04's bound already admits rooms that talk first. What runs differently here is the share of rooms whose talk with neighbours is the work of building, not of keeping.

This is description, not a test. A04's expectation in form A is 0.471 (2 within-case datings over 705 rooms, times 166), so A04 is not-testable-here (section 10).

## 9. Fourth-order themes over- and under-represented

The rule was logged at D5a-01 before it ran (`_analysis/d5_themes.py`), and it is applied here to the defining members' codes (`_analysis/d5f_facts.py`). A member's coded concepts are counted by the fourth-order themes of their second-order theme's placements, and the form's pooled share on a theme is set against the pooled share over all 705 rooms. Over-represented: a ratio of 1.5 or more, with the theme present in 5 members or more. Under-represented: a ratio of 0.67 or less, with a population share of 1 per cent or more. These are shares of what the coders coded in these rooms, never a property of the rooms (contract section 5).

**Over-represented (5).**

- **Symbolic boundaries:** 0.8 per cent of the defining members' coded concepts against 0.4 per cent (ratio 1.77), in 12 members.
- **Negotiated order:** 16.3 per cent of the defining members' coded concepts against 9.7 per cent (ratio 1.68), in 129 members.
- **Territoriality:** 6.1 per cent of the defining members' coded concepts against 3.8 per cent (ratio 1.63), in 62 members.
- **Standardization of output:** 3.2 per cent of the defining members' coded concepts against 2.1 per cent (ratio 1.54), in 66 members.
- **Repair work:** 15.5 per cent of the defining members' coded concepts against 10.2 per cent (ratio 1.51), in 124 members.

In the rooms' words, from members holding the largest share on each theme (`_analysis/d5f_theme_quotes.py`): Negotiated order, "Is it possible to move the carrots below us to another spot, to make room for Balrog?" [cavestory/c0034]. Territoriality, "The Vineshroom is gone..." [vinesauce/c0057]. Standardization of output, "I say Lechuck to the left of guybrush, under bender. we can get most of him." [MonkeyIsland/c0010]. Repair work, "We need to get a black border around the V" [Villanova/c0016]. Symbolic boundaries, "Our Night's Watch did a good job :)" [philippines/c0354].

**Under-represented (4):** Keying (ratio 0.33), Neo-tribes (ratio 0.40), Meta-organization (ratio 0.57), Workarounds (ratio 0.62).

Negotiated order is the form's change signature, so its excess in the codes partly restates the cut; the codes are a third of the distance. Keying, the April Fools frame, is coded at a third of the population's share. These rooms talked about the canvas and its neighbours more, and about their sub's play, its tribes and its coalitions less.

## 10. Arrows present, absent or not-testable-here

Section 1's arithmetic, declared at D5a-01: an arrow's expectation in a form is its within-case datings (its `subs`, counted over the 705 analysed rooms) over 705, times the form's n, here 166. Below one the arrow is not-testable-here, and no absence, boundary condition or failed proposition may be written from it. In form A the expectations run from 0.000 to 0.942:

- A01 (P01 to P03): 2 datings, expected 0.471; not-testable-here
- A02 (R01 to P01): 2 datings, expected 0.471; not-testable-here
- A03 (P03 to P05): 2 datings, expected 0.471; not-testable-here
- A04 (P05 to P08): 2 datings, expected 0.471; not-testable-here
- A05 (P08 to P07): 3 datings, expected 0.706; not-testable-here
- A06 (P05 to P14): 3 datings, expected 0.706; not-testable-here
- A07 (P03 to P11): 2 datings, expected 0.471; not-testable-here
- A08 (P11 to P12): 2 datings, expected 0.471; not-testable-here
- A09 (P12 to P13): 2 datings, expected 0.471; not-testable-here
- A10 (K02 to P10): 2 datings, expected 0.471; not-testable-here
- A11 (P02 to P04): 2 datings, expected 0.471; not-testable-here
- A12 (P01 to P15): 3 datings, expected 0.706; not-testable-here
- A13 (P05 to P16): 4 datings, expected 0.942; not-testable-here
- A14 (P08 to P16): 4 datings, expected 0.942; not-testable-here
- A15 (P01 to P09): 4 datings, expected 0.942; not-testable-here
- A16 (P09 to P07): 4 datings, expected 0.942; not-testable-here
- A17 (P09 to P08): 4 datings, expected 0.942; not-testable-here
- A18 (P09 to P18): 4 datings, expected 0.942; not-testable-here
- A19 (P05 to P17): 4 datings, expected 0.942; not-testable-here
- A20 (P01 to P20): 3 datings, expected 0.706; not-testable-here
- A21 (P08 to P21): 0 datings, expected 0.000; not-testable-here

**Present: none. Absent: none. Not-testable-here: all 21.** Form A is the largest of the six forms, and still no arrow reaches an expectation of one. Members' current-ledger lines on an arrow (sections 7 and 8) are description only. Members among an arrow's within-case datings: r/clg (A18); r/foxes (A06); r/lakers (A08); r/littlewitchacademia (A14); r/monsterhunter (A03); r/paranatural (A10); r/roosterteeth (A05); r/sooners (A14, A17); r/switzerland (A04); r/thailand (A17); r/TheFarLeftSide (A06); r/uiuc (A09). That is arithmetic about the model's own evidence, and it tests nothing in the form.

**Propositions.** N01, N02, N03, N04, N05, N06, N07, N08, N09; the highest expectation among the arrows they rest on is 0.942. Every proposition is not testable here; none holds and none fails against a real expectation. No `findings.jsonl` line is bounded from this form.

## 11. How representative members do the work

**The rule, logged at this leg's opening before it ran** (`_analysis/d5f_facts.py`). Fit is a defining member's distance to the form's centre in the allocation's 892 columns. The best two are the nearest members whose selected changes and coded concepts are at or above the form's defining medians (10 changes, 99 concepts), so that each record can be told. The least well is the farthest defining member. The member read at length is, among the ten nearest, the one with the most selected changes not read at length earlier in stage D5. The rule chose r/FloydVsVoid twice, as the best fit and as the member read at length.

**Best fit, read at length: r/FloydVsVoid** (distance 0.690; 26 selected changes; 205 coded concepts; first-return verdict composes, re-check grade composes with residue; in F15, F30 and F31). I read it at length because the rule chose it, and because it holds every part of the form. Its members built a prism and a rainbow against a rival room, the Void, whose members declared the room's resistance futile. The opening call: "We're Taking on the Void! Join the Fight!" [FloydVsVoid/c0001]. Their terms ran in several directions at once. They made a deal for space: "we will help maintain the blackness in the core" [FloydVsVoid/c0077]. They asked whether they could reach another neighbour at all: "Can we even reach out to them?" [FloydVsVoid/c0079]. They agreed a line with the Swiss flag's builders: "instead of blending the mountains with the prism can we just do like a black line that separates the prism from the mountains." [FloydVsVoid/c0204], answered "sure thing!" [FloydVsVoid/c0205]. The Swiss gave their reason for helping: "You guys were great to incorporate our prism into your mountains and I would like to see the cheese stay intact." [FloydVsVoid/c0110]. An alliance post told members what to leave alone: "Leave /r/place logo and Anime Poot" [FloydVsVoid/c0088]. When r/ireland complained, "Please stop invading the Irish flag" [FloydVsVoid/c0126], a member repaired the flag, "im using some of my pixels to replace flag pixels" [FloydVsVoid/c0129], and stated the limit of the room's terms: placers outside the sub and the chat "arent under our direct control" [FloydVsVoid/c0128]. The plan had to reach the members as well: "That's still the wrong plan in the main post. Here's the new one" [FloydVsVoid/c0153]. When the room lost a piece of the work, a member asked for the chat to spread the word: "Is anyone on the Discord chat who can let everyone know?" [FloydVsVoid/c0161]. Another answered, "I've sent about 100 messages in the last hour. i think we're making headway." [FloydVsVoid/c0162]. What is unrepresentative about it: it organized against a rival room as well as with its neighbours, and its record is larger than most. It holds 205 coded concepts against the form's defining median of 99, and 26 selected changes against 10.

**Second best fit: r/stardewvalley** (distance 0.704; 11 selected changes; 126 coded concepts; first-return verdict composes, re-check grade composes with residue; in F09, F15, F21, F28 and F32). Its members built small figures, a Junimo and a chicken, among larger works, and they settled with each neighbour in turn. A member was "in contact with the redditors over on" another sub "regarding their Lucio pixel art right above our Junimo." [stardewvalley/c0010]. A neighbour asked one of its builders to move: "Considering Stardew already had a Junimo, and we were making it first, could you move it somewhere else?" [stardewvalley/c0036]. The builder left: "I've stopped working on it and now working on the starfruit next to the Junimo." [stardewvalley/c0037]. The room offered to trim its chicken for the HotS border (section 1), offered to trade defence for upkeep, "would you be willing to help defend our other properties in exchange for help maintaining your logo" [stardewvalley/c0114], and said where its terms stopped: "There is compromise with most of the swedes on discord but not the rouge ones." [stardewvalley/c0086].

**Least well: r/futanari** (distance 1.383; 5 selected changes; 14 coded concepts; first-return verdict composes; in no branch; its point lies nearer form D's centre than form A's). Its record is one piece. A member showed it, "Place thing I did over a couple hours" [futanari/c0001], gave its place, "It's over at 163, 262 if you all want to add or check it out." [futanari/c0002], and received praise: "Very gud" [futanari/c0003]. After the close another member saved it: "Our place on r/place is gone, but I captured its most perfect form" [futanari/c0012]. Its five lines restrict the call, the marking and the record (A01, A07, A08, P11, P12). Nothing in it is between neighbours. It is in form A because Ward's method put it there; by the centres it lies between forms A and D.

## 12. The branches its rooms come from

J asked that stage D6 build on the forms with the 35 branches as the level below. The branches do not nest in the forms: a branch was cut on one shared key, a form gathers rooms by the whole mix of their changes and codes. The table gives, for every branch, how many of its rooms are in form A, and the branch's share in A against A's share of the 705 rooms (166 of 705, 0.235). A ratio of 1 is what a branch would show if its rooms fell in the forms at random.

**What the table shows.** Ten branches lean to form A at 1.5 times its share or more. They are the branches of the order between rooms and of the plan:
- F19, credit contested during the work: 8 of 14.
- F26, the telling clause not shown at the border: 13 of 23.
- F28, help at the border conditional: 12 of 22.
- F15, the plan kept current: 20 of 42.
- F10, a deal carried out as work: 17 of 38.
- F17, the marking provisional and contested: 16 of 36.
- F32, the marking returns to keeping: 9 of 21.
- F30, the chat seen through its invitations: 10 of 24.
- F18, success judged while upkeep continues: 6 of 15.
- F31, hosting as one-off permission: 8 of 22.

None of the 103 rooms of F01, the April Fools play, and none of its five subforms is in form A. No branch lies mostly in form A: the largest share is F19's, 0.571. So the branches below form A are its facets, each shared with other forms.

**Rooms in no branch.** 60 rooms (36 defining): r/2007scape, r/ainbowroad, r/auburn (thin), r/batman, r/carletonu (thin), r/cirkeltrek (thin), r/compsoc (thin), r/Cornwall (thin), r/detroitredwings, r/DevonUK (thin), r/Dorset, r/evedreddit (thin), r/finland, r/fireemblem, r/futanari, r/germany, r/giantbomb, r/Goodboye, r/halo, r/hsv, r/iceland (thin), r/ireland, r/k_on, r/landry (thin), r/Lugarix (core), r/MiamiHurricanes, r/monsterhunter, r/mordhau (thin), r/mysterydungeon, r/neutralmilkhotel (thin), r/norway, r/npr, r/nVade, r/oneshot, r/orderofthebluecorner, r/pansexual (thin), r/parabola (thin), r/paranatural, r/peterdraws (thin), r/PinkUnion, r/placehearts, r/rainbowgrid, r/ReBoot (thin), r/redvsblue (thin), r/roosterteeth, r/seventeen (thin), r/signal (core), r/sonicthehedgehog, r/Summit1G (thin), r/TeamYellowPlace (thin), r/telegram, r/texastech, r/TheB1G (thin), r/uva, r/VelvetUnderground (thin), r/vermont, r/Villanova, r/winnipegjets, r/xenoblade_chronicles, r/yerbamate (core).

## 13. The nearest form and what separates them

**The nearest form is B**, the work behind the thread: the chat, the scripts and raiding. The distances between form A's centre and the others are B 0.366, C 0.394, D 0.407, F 0.567, E 0.852. In the tree, A stays a form of its own down to four forms; at three it joins B and C (the design and its marking), and the April Fools play (E) is the last to join the rest. A and B are separated by what the rooms changed: A's members change the order between rooms and the plan, B's the chat, the scripts and attack calls.

**The rooms between forms.** C 14, B 12, D 7, F 1, E 1: these are the forms whose centres lie nearer than A's to its defining members, 35 rooms in all. The room that could have gone either way, the defining member with the smallest margin to another centre, is r/drawhelix (7 selected changes, 67 coded concepts, in F10). Its point lies nearer form C's centre. Its record has both: a border with a neighbour to settle, "Contact r/ainbowroad to get them to put this on their official live thread." [drawhelix/c0024], discussed in the room first, "And I do plan on contacting them, but wanted to discuss it here." [drawhelix/c0025], and a figure revised and kept, which is form C's work.

## 14. The split below the form

**The rule, logged at this leg's opening before it ran** (`_analysis/d5f_split.py`, on `room-forms-tree-rooms.tsv`). A split reads as a split when both parts hold 10 defining rooms or more and each part has a fourth-order change column (a node or a link) at 1.5 times the parent's defining share or more, held by a third of the part or more and by fewer in the other part. The walk descends only while splits read.

| group | splits at k | part | defining rooms | all rooms | change columns the part leans to | reads as a split |
|---|---|---|---|---|---|---|
| A | 7 | A.1 | 74 | 96 | none | no |
| A | 7 | A.2 | 61 | 70 | Completion ritual (1.67 times the parent's share; 0.738 of the part, 0.324 of the other); Standardization of output (2.06 times the parent's share; 0.721 of the part, 0.081 of the other); Mobilization (2.05 times the parent's share; 0.508 of the part, 0.068 of the other) | no |

**Form A's first split, at seven forms, does not read as a split.** A.2 (61 defining rooms, 70 rooms in all) leans its own way: to the completion ritual, the standardization of output and mobilization. It is the eight-form cut's "plan made and announced". A.1 (74 defining rooms, 96 in all) has no column of its own at 1.5 times the form's share. It is the form's centre: the terms between neighbours. Both hold the form's signature. The share of defining rooms holding each signature theme in each part: A.1: Negotiated order 0.905, Completion ritual 0.324, Standardization of output 0.081; A.2: Negotiated order 0.820, Completion ritual 0.738, Standardization of output 0.721. So A.2 is the terms with the plan added, not a second kind of room, and the walk stops at the form. A.2 is a candidate subform for D6 (`notes-D5.md`), not cut here.

## 15. The thin and core rooms placed here

**Thin rooms (28),** placed by the whole mix of their changes and codes at the nearest form centre: r/auburn (4 changes, 49 concepts), r/carletonu (3 changes, 7 concepts), r/CelticFc (1 change, 18 concepts), r/cirkeltrek (3 changes, 308 concepts), r/compsoc (2 changes, 9 concepts), r/Cornwall (1 change, 11 concepts), r/croatia (4 changes, 237 concepts), r/DevonUK (2 changes, 24 concepts), r/Dustforce (4 changes, 47 concepts), r/evedreddit (1 change, 30 concepts), r/hungary (4 changes, 64 concepts), r/iceland (1 change, 77 concepts), r/landry (4 changes, 12 concepts), r/mamamoo (1 change, 10 concepts), r/mordhau (3 changes, 34 concepts), r/neutralmilkhotel (3 changes, 25 concepts), r/onepunchman (4 changes, 130 concepts), r/pansexual (3 changes, 21 concepts), r/parabola (3 changes, 20 concepts), r/peterdraws (3 changes, 10 concepts), r/ReBoot (2 changes, 4 concepts), r/redvsblue (3 changes, 41 concepts), r/seolhyun (3 changes, 38 concepts), r/seventeen (2 changes, 12 concepts), r/Summit1G (4 changes, 148 concepts), r/TeamYellowPlace (3 changes, 63 concepts), r/TheB1G (4 changes, 52 concepts), r/VelvetUnderground (2 changes, 15 concepts).

Their 77 selected lines weigh less and enter no share above. The most frequent are P03 link 6 (r/auburn, r/Cornwall, r/Dustforce, r/redvsblue, r/seolhyun); A04 restrict 6 (r/auburn, r/croatia, r/neutralmilkhotel, r/redvsblue, r/Summit1G, r/TheB1G); P08 add-step 5 (r/Dustforce, r/onepunchman, r/seolhyun, r/VelvetUnderground); P11 link 4 (r/hungary, r/neutralmilkhotel, r/ReBoot, r/seventeen); P05 add-step 4 (r/mordhau, r/neutralmilkhotel, r/parabola, r/TeamYellowPlace); P02 link 4 (r/carletonu, r/iceland, r/parabola, r/VelvetUnderground); P04 add-step 3 (r/cirkeltrek, r/compsoc, r/Dustforce); P07 add-step 3 (r/pansexual, r/seventeen, r/TeamYellowPlace). They lean the same way as the defining members, to border talk while building (A04 restricted in 6) and to the steps of making terms (P08 add-step in 4).

**Core rooms (3),** with no selected change, placed by their codes alone at the nearest centre in the code columns: r/Lugarix (5 concepts; verdict cannot-tell), r/signal (6 concepts; verdict composes), r/yerbamate (1 concept; verdict cannot-tell). Their placement rests on 1 to 6 coded concepts each and is weak. Two of them are the form's only rooms whose verdict is cannot tell.

## 16. The form test

**The constructs.** P08 (borders, truces and deals), P07 (sparing) and P05 (keeping), joined at the fourth-order theme T4-016 (Negotiated order), with P21 (who may commit the room) and the arrows A04, A05 and A14. For the part A.2, P04 (the template), P11 (the marking) and P12 (the record).

**The relations.** The rooms make terms with neighbours while they build, and they spare neighbours before any terms are made. The terms bind only the placers, and the scripts, they reach, and the rooms work to reach them. The same holds for the room's own plan. The first relation is the form's: the negotiated order is changed by 86.7 per cent of its defining members. The second is held by 29 of 135 in the lines I read. The relations restate bounds the model already writes for A04 and A05, and they add the work of making and spreading terms that the model leaves unstated.

**Is it falsifiable?** Yes. A room that made terms only after keeping, or whose agreements bound placers who never heard of them, would fall outside the relations. Such rooms exist in the population: A04's within-case datings, r/switzerland (a member here) and r/DestinyTheGame, are rooms whose first upkeep came before their first border talk.

**The four organizing problems.** The form binds information provision: terms and plans must reach the placers, and the rooms' added steps are the means (messages, warnings, updated templates, retired calls). It binds the division of tasks between rooms: a border divides the canvas between two works. It leaves the allocation of members to tasks free, and it touches reward only through traded help (A14), which the record mostly shows as offers. A remainder is supported: restraint that rests on a norm, offered before any terms, and apology when a room learns what it covered. None of the four problems names it.

**What varies among members.** Whether the plan is announced as well as the terms (A.2 against A.1, section 14), whether the room also organized against a rival room (r/FloydVsVoid), and how far its terms reached. No subform stands on the rule; A.2 is a candidate for D6.

**Result: a lean of the population, and a form in a weak sense.** The form binds constructs of canvas organizing and states their relations, and the members' words show them. But its members share a lean, not one change. Its relations mostly restate the bounds of two arrows, and about a quarter of its defining rooms (35 of 135) lie nearer another centre. I report it as a pole of the continuum: the rooms whose organizing was mostly about the order between rooms.

## 17. What would make you doubt this is a form at all

Four things make me question it.

First, the cut. The form is one of six poles that J ruled for a short appendix, cut from a distance whose stability is about 0.21. Its largest part, A.1, is the centre of a continuum, and 35 of its defining rooms lie nearer another centre. A different weighting would move many of its rooms (`room-forms-allocation.md`, section 5).

Second, my sort of the restrict lines. One reader sorted 432 lines, and no second reader checked them. The line between *the arrow fails here* and *neither* (a scope or a condition) is a judgement in many lines on A05 and A10.

Third, the arrows' bounds. The form's most frequent restrictions, on A04 and A05, restate what the model already says in those arrows' bounds. What sets the form apart may be how often its rooms talked with neighbours, not a different way of doing it.

Fourth, the survival figures, from the record, never from the canvas. The median organizing end is hour 71.99 for the 163 members with one, and the mean aftermath share is 0.0159. The coded `work_remained` field says kept in 79 members, lost in 47 and silent in 40. These figures are not compared here, and nothing in this account rests on them.

What would undo the form: a cut on a different weighting in which the rooms of form A scatter evenly over the other forms, or a reading of the members' threads in which the terms they made were no different from those of rooms in other forms that talked with neighbours.
