The model, stage C4: read against the field

The model is typed: elements in model/elements.jsonl, arrows in model/arrows.jsonl, every change in model/history.jsonl, loops in model/loops.jsonl (empty at pass 5). Pass 1's version is model.md; passes 2 to 4 are model-p2.md to model-p4.md. All are kept unchanged; model-p3.md is the text the reviewer read (sha256 aa75ee6c…).

What stage C4 changed

This file supersedes model-C3.md whole (rule 18). Stage C4 read the model against the field. The field is the model of the event that a separate analyst built from r/place (field/model.md), with that analyst's check of my model (field/check.md). What each comparison found is in field-C4.md. Stage C4 changed:

• Three tentative entries from the field. P21: members dispute who may commit the room to an agreement with other rooms. A21: an arrow from deals and truces to that dispute. P22: after placement ends, members contest which version of the canvas and of the event is kept. Each is origin: from-field and status: tentative, with the field's threads and items. None is counted. None is in the standing count. Stage D asks every room about each. They are listed in their own section, before the theorised arrows.
• One sentence bounded. The model said that a room's organizing for this canvas is over at hour 73. Placement on the canvas ends at hour 73. Organizing around its records and copies goes on (field-C4.md, list 3, item 1).
• Two disagreements printed beside the model. Beside F-006 and C01, the field shows authority sought between groups, which is not decided order placed. Beside A04, the field shows one early buffer negotiated in r/place.
• One limit written in. An order count dates each concept by the hour of its post, and a retrospective report does not date the act it reports.
• Two construct declarations amended (structure-C4.md). Standardization of output no longer says that a template replaces argument or is the strongest coordination at scale. Boundary work no longer says that every room existed before the canvas.

No standing element or arrow was added, bounded, demoted or withdrawn. No strength or count changed. No tier was recut. No finding changed. The story is not rewritten here; that is stage C5's.

The text below is stage C3's, with these changes written into it.

What stage C3 changed

This file supersedes model-p5.md whole (rule 18). Stage C3 read the pass 5 model against the explanation literature; what each work did is in literature-C3.md. Stage C3 changed:

• A bound on decided order (C3a). F-006 is superseded by a bounded line, prompted by O'Mahony and Ferraro (2007, verified). Decided order gathers in the small canvas-born factions that govern a territory or rule on guests: 7 of 39 such rooms carry it, against 39 of 666 others, held to room size (p 0.014), and only in the smaller rooms. C01's statement is unchanged.
• Two mechanisms from a distant field (C3b). The mechanisms of A12 (the one-line answer to a call) and A16 (an attack call refused inside the room) are taken from conversation analysis (recalled: Schegloff and Sacks 1973; Pomerantz 1984; Levinson 1983). A call is the first part of a pair. Joining is the preferred answer and comes bare; refusing is dispreferred and comes with a reason, which in a refusal of an attack call states the room's norm or the attack's cost. Tested on attack calls (F-014): refusals gave a reason in 23 of 38 read pairs, acceptances in 2 of 14. The stage C2 sentences are kept beside the new ones, in model/arrows.jsonl and below.
• The concept renamed (C3b). The one-line enrolment is a relabelling of conversation analysis's preferred acceptance (concept-C3.md). Its claimed function as the room's head count failed its test (F-015, weak).
• Two construct declarations amended (C3b). Stigmergy and Decided order each name a construct from the shelf they may be mistaken for (structure-C3.md).

No element was added or withdrawn; no arrow was added, bounded, demoted or withdrawn; no strength or count changed; no tier was recut. The story is not rewritten here; that is stage C5's.

The text below is pass 5's, with these changes written into it.

Pass 5 is the last closing pass. It worked from pass 4's state under J's ruling on QC2-002: the criterion is a guide, not the judge; each change is kept while the evidence leads me to believe it; no element is loosened to fit a room; and membership naming the rival in the same turn as the attack is carried as a claim in the rooms' words, untested for order. Pass 5 changed:

• one claim added, C02, untested for order, on finding F-013;
• two forms stated as boundaries at the return: colour factions the canvas gathered, and hosts ruling on guests;
• the story's contest and closing sections (model/story-p5.md).

Pass 5 kept every pass 4 change, each for the reason given in notes-C2.md (pass 5, declaration 2). No arrow was added, bounded, demoted or withdrawn, and no tier was recut.

The pass 5 story was read against 35 rooms drawn by seed 20261019 before any was opened. It told 16, told 19 with a residue and left none untold (pass 3: 16, 16, 0; pass 4: 11, 21, 0). Of the 21 rooms carried from pass 4's residue, the claim C02 told 7. Fresh rooms carried a residue at pass 4's rate: 5 of 11 against 5 of 13. The model rests on pass 5 (notes-C2.md, pass 5).

Pass 4 answered the reviewer's return (C2c) and the interview's points. It changed:

• two fourth-order recuts, each by a rule written first: hosting's four third-order themes left Meta-organization for Territoriality, and the land's flag and emblems left Flagging the nation for Collective representation;
• three elements restated: the coalition element (P17) narrowed to coalitions, the call to settle the mark (P02) widened to the land's flag and emblems, and the candidate membership carried in (K04) narrowed to the nation beyond the mark;
• an audit of every instance: 48 support transitions checked six ways, 14 failing a check, each reported as failing and none swapped;
• recounts: A19 on coalitions alone, A11 on the widened P02, A20 by actor while the canvas runs, and the four arrows that start from the call with joining lines stripped out;
• the failure clause counted for every order arrow;
• the reviewer's accepted errors carried into the text: new instances for A02, A04 and A05, transformers as a failure of A20's mechanism, "no posts in the week before the canvas" in place of "founded by the canvas", bounds told as bounds, and "order fails in" in place of "Present".

At pass 4 no arrow was added, demoted or withdrawn, and no element was added.

Earlier passes: pass 3 added the host's line (P20, A20), two candidates (K04, P19) and A10's bound. Pass 2 added P16 to P18, the candidate K03, A13 to A19, bounds on A04, A06 and A07, and the dimension Contention (D08).

The counts come from out/_analysis/c2_arrow_evidence.py. Pass 4's outputs are c2_arrow_evidence-p4a.txt (retests after the recuts), -p4b.txt (the host's line by actor before hour 73), -p4c.txt (the call without joining lines) and -p4d.txt (the failure clauses). The audit is c2d_instance_audit-p4.txt; the joining lines dropped are listed in c2d_enrol_drop.txt. The apparatus tables are printed by c2_model_tables.py (c2_model_tables-p4.md), the dimension masses by c2_dim_mass.py (c2_dim_mass-p4.txt), the unused themes by c2_unused_t3.py (c2_unused_t3-p4.md), and each arrow's pass 4 facts by c2d_model_facts_p4.py (c2d_model_facts-p4.txt).

The model relates presences and their order in time, never amounts. No coder wrote down a covariation between degrees, so no arrow is drawn between degrees.

What the model says, in prose

The contract asks the model for four things: how a scattered readership becomes able to act and how it settles what to act on; what sends a group back to that beginning; what brought organizing about when it came, and what followed; and what is left behind. Pass 5's model is a spine, a fork between rooms, a contest, and a close, with the host sub's answer to the calls beside the spine.

How a scattered readership becomes able to act. A member proposes a mark or begins it (R01). Calls gather around the start [A02], and calls bring the hands that build [A01]. The cheapest answer to a call is one bare line, "On it.", which commits a member and asks for nothing back [A12]. Joining is the answer a call prefers, so it needs no reason; refusing is dispreferred and comes with one (conversation analysis, recalled; F-014). The coders placed some of these joining lines among the calls. A pattern that over-reads finds at most 228 of the 1,980 concepts cited under the call's themes. With all 228 stripped out, each of the four counted arrows that start from the call still beats the null. Where a member placed first, the call follows the first build (A01's bound). The calls fill the host sub, and the sub draws a line around canvas talk: a megathread, removals under its rules, a canvas sub, members objecting to the flood [A20]. While the canvas runs, the calls come before the host sub's rulings in 102 of 118 rooms and before members' objections in 57 of 64 (finding F-010). One room in nine has no posts in the week before the canvas (78 of 705). An empty week does not show that the canvas founded a room. Side subs opened for the canvas, quiet subs and bodies the canvas gathered all have one.

How it settles what to act on. The room settles what its mark will show (P02). A national room's mark is mostly the land's flag or its emblems, and settling that is the same act as settling any room's picture. Inside a reply thread, a template settles a design under argument [A11]. Across rooms the first template is as likely to come before design talk as after it, and it can arrive with the first call (A11's bound). The half-built mark tells the next placer what is missing (P03). Decided order, such as a leader, a vote or an oath, is rare (C01; finding F-006). It gathers in the small canvas-born factions that govern a territory or rule on guests (F-006, bounded at C3a, prompted by O'Mahony and Ferraro 2007). The field shows members asking who may commit a group, between large factions and after the close. That is authority sought, not decided order placed, and F-006 stands (field-C4.md, list 3, item 4; the tentative P21).

What brought organizing about when it came, and what followed. Organizing came when someone started and others answered [A02] [A01]. The April Fools frame (K01) does not, across rooms, delay that start (finding F-009). Then the road forks.

• Keeping the work. Once a mark stands, keeping it becomes the work [A03]. Upkeep under attack outruns one pixel per interval, and members turn to scripts and spare accounts [A06].
• Keeping the work brings in other rooms. Upkeep brings a room up against the neighbours whose pixels erode it, and the room talks with them [A04]. A settled border gives members a line they keep [A05]. Short of hands, a room also turns to other rooms for help and receives it [A13]. Talk over a border can open a channel through which the two rooms trade help [A14]. A room keeping its work joins other rooms whose works face the same threat in a coalition [A19] (finding F-008).
• The contest. A call to the canvas can also turn its hands against a rival's work [A15]. A room's own call to attack is mostly answered inside the room: members refuse it, rein the attackers in or apologise [A16], or invoke a truce or propose a deal [A17] (finding F-007). Where the attack goes on, it is carried on in talk: taunts, chants, claims of victory, a salute after the fight [A18].

What sends a group back to the beginning. A loss. A room that judges it has too few hands stops fighting for its spot and moves [A10]. A room inside a coalition can also move by the coalition's plan, and a late room may write its reason after the move (A10's bound). After the move, calls fall from the crisis before it: a call comes in the six hours after the first move in 0.392 of moving rooms, against 0.500 in the six hours before. The room keeps calling more than rooms that did not move, which stand at 0.290 at the same hours (finding F-002, bounded). It goes back to choosing a spot, and often to a fresh call.

What is left behind. A finished mark is celebrated together [A07]; where hour 73 cut the work unfinished, the room marks the attempt (A07's bound). What is celebrated is recorded [A08]. What is recorded is carried on into banners, later canvases and lasting groups [A09] (finding F-004). Placement stops at hour 73. After it, a room can celebrate, record, carry on, keep up its rivalries in talk, and work on copies of the canvas (the tentative P22).

Conditions. The April Fools frame (K01) and doubt about numbers (K02) are conditions. Membership carried in from outside the canvas is in the structure as Collective identity and not in the model. Two candidates stand for it:

• a quarrel carried in (K03): its one test had 9 rooms and failed;
• membership carried in (K04), narrowed at pass 4 to the nation claimed beyond the mark, colour faiths and frames: its first concept comes before the first attack in 52 of 126 rooms (0.413), below the null mean of 0.532 (F-011). The reverse, attack first and membership told after, shows in that count. It was not declared and is not tested.

A claim, untested for order (C02, pass 5). In some rooms a tie the members had before the canvas names the rival in the same turn that calls for or carries out the attack: a league or school rivalry, a nation's history, an ideology, lore. "You mean WPI? I'm down for a lil interpolytechnic griefing." [rpi/c0022]. Read in the story rooms of passes 1 to 4, 10 turns in 7 rooms show it (finding F-013): unitedkingdom, anarcho_capitalism, completeanarchy, CKCrusaders, lakers, cardinals and rpi. The tie and the attack are one turn, so no order statement can count it, and no share of rooms is claimed. It is carried in the rooms' words by J's ruling on QC2-002. The membership candidate (K04) stays a candidate, and F-011 stands beside the claim: membership does not come before the attack more than chance, and in these turns it names the rival in the attack itself.

Hosting. One room's work living on another's mark under the host's rule is a candidate (P19). From pass 4 its four themes sit in Territoriality: hosting is a claim on space, not a partnership. It follows neither exchange, coalition, upkeep nor border talk. Hosts that give a ground for a ruling most often give space or design (F-012). The six hosts whose own rulings are cited all have no posts in the week before the canvas. Hosts with readers before the canvas (sweden, catalunya, smashbros) rule on guests too.

The reviewer's errors, as carried here

The reviewer's nine errors (C2c, review-C2.md) were answered under rule 13 in notes-C2.md. The next list gives where each accepted error lands in this file:

• error 2, A02's instances were joining lines: new instances under A02;
• error 3, A04's instances: new instances under A04, with switzerland's own order beside them;
• error 4, A05's one-turn instance: a transition under A05;
• error 5, transformers: a failure of A20's mechanism, under A20 and in its bound;
• error 6 in part and error 8, bounds tagged as uses: in this file and in story-p4.md a bound is named as the arrow's bound;
• error 7, "founded by the canvas": "no posts in the week before the canvas", in the prose above and under where the model should break;
• error 9, "Present": every order arrow now says "the order fails in N of M rooms" and gives the failure clause's count apart.

Error 1 (A01's instance as a coordinate) was refused. The reviewer's reading is printed beside the claim under A01.

The elements

The next table lists the 28 elements with their kind, statement, tier, dimension and range. K03, K04 and P19 are candidates, not in the model. The other 25 stand. P02, P17 and K04 were restated at pass 4. C02 was added at pass 5, untested for order.

Every element has a range. 21 of the 25 standing elements are named for what they do. Four (K01, K02, C01, C02) are named for a state or a pattern. Fewer than a third are named for what they are about, so the model is not a lattice. K04, a candidate, is named for what it is about.

Why 25. Pass 1's 20 elements stand. Pass 2 added three because the pass 1 story could not tell what 9, 6 and 4 of its twenty rooms did: exchange between rooms (9 rooms), the contest carried on in talk (6), and coalitions (the rooms that entered the canvas through other rooms). Pass 3 added the host's line around canvas talk, which the pass 2 story could not tell in 4 of its 32 rooms. Pass 4 added none. Pass 5 adds the claim C02 by J's ruling on QC2-002: in 7 of the story rooms read at passes 1 to 4, a tie the members had before the canvas names the rival in the same turn as the attack, and no order statement can count that.

What pass 4 restated.

• P17 is now coalitions alone: kindred hubs, alliances, shared chats, tallies of kindred works, joint marks. Hosting left it with its themes, so P17 no longer holds a room ruling on guests.
• P02 now holds making the land's flag or its emblems the mark. The rule written first: a theme whose acts draw or settle what the room's own mark shows goes with the mark's content. Read against their gates, two members of Flagging the nation do that, building the homeland's flag (T3-065) and drawing national emblems (T3-113). The other ten claim, argue or narrate the nation beyond the mark.
• K04 loses those two themes and keeps the nation beyond the mark, colour faiths and frames.

Each process and condition enters only with a grounded arrow. The two claims stand on findings and carry no arrow: C01 on F-006, and C02 on F-013, untested for order. The quarrel carried in, membership carried in and hosting had no grounded arrow and stay candidates. P19's four themes are in Territoriality and are not used while P19 is a candidate.

The arrows

The next table lists the 20 arrows in the model. For each it gives the kind, the strength, the rooms where the connection statement holds out of those carrying both elements, the permutation null (500 shuffles of labels within each room, seed 20261014), the holds on the early and late sides of the onset contrast, and whether the base rate is beaten. A11 and A19 were recounted at pass 4.

The connection statement, written before every count: "in a room carrying both, the first concept of FROM comes before the first concept of TO". It is a statement of order. The null holds each room's coded turns and their hours fixed, and shuffles which element each turn belongs to. A relation that holds nearly everywhere is not deleted by its base rate. A03, A16 and A20 are in part constitutive: a work must stand before it can be kept, an attack must be called before it can be reined in, and a canvas post must exist before it can be removed or objected to.

The failure clause, counted at pass 4. Each order arrow's failure clause says that TO comes only before any FROM. The second statement, "in a room carrying both, some concept of TO comes after the first concept of FROM", fails in exactly those rooms. Below, each arrow gives two numbers: the rooms where the order statement fails, and the smaller number where the failure clause holds. Pass 3's "Present" counted the first and labelled it as the second (the reviewer's error 9).

Tests, by pass. Pass 2 ran twelve order tests and seven beat the null; A14 and A19 beat the 95th percentile by 0.009 and 0.044, so they are thin. Pass 3 ran seven and three beat it; one entered the model (A20). Pass 4 ran eight declared tests; at 0.05 each, eight give about 0.4 false passes by chance. Three beat the null: upkeep then coalition on coalitions alone (A19's recount, 0.719 against a 95th percentile of 0.678), and the calls before the host sub's rulings and before members' objections while the canvas runs. Five did not: border talk then coalition (0.679, at the 95th percentile and not above it), exchange then coalition, border talk then hosting, A11 on the widened P02, and membership then attack on the narrowed K04. Pass 4 also recounted standing arrows without adding tests: A20 whole before hour 73, the four arrows from the call without joining lines, and the failure clause of 18 order arrows.

The instance audit (pass 4). Every support transition of every arrow was checked six ways:

• (i) the room holds the arrow's order;
• (ii) both turns are in one thread, the second replies at some depth to the first, by another author, later;
• (iii) both lines are cited under the two elements' themes;
• (iv) the first line's words, read whole, do the FROM act;
• (v) the second line does the TO act as a new act answering the first;
• (vi) the printed quote is the store's text, with its hour and the interval.

Checks (i), (ii), (iii) and (vi) ran by script and (iv) and (v) were read. Of 48 transitions, 34 pass and 14 fail. 9 fail check (i), because the room does not hold the order. 3 fail check (iii). 3 fail on reading, and latin fails both (i) and (iv). Every failing transition stays in arrows.jsonl with its failure in its audit field. None was swapped out. Every arrow but A10 keeps at least one passing transition. A10 rests on quotes.

Every arrow is grounded codes-read: the concepts were read across rooms, and each arrow rests on quotes and, except A10, a transition in one thread that passes the audit.

Each arrow, with its mechanism, the observation that would show it failed, the two failure counts, its bound, the sampled rooms that failed, and its instances with their audit:

• A01, the call brings the hands that build (P01 to P03). Mechanism: a call brings members to the canvas who then start or extend the mark and say how far it has come. Fails if: build reports come only before any call. The order fails in 53 of 190 rooms; the failure clause holds in 8. Without joining lines: 132 of 189 (0.698) against a 95th percentile of 0.492. Bound: where a member has begun the mark before any call, the call follows the first build. Sampled and failing: xenoblade_chronicles. Transitions: 164 in 70 rooms. Instance: "Help us draw Metroid over at /r/place!" [metroid/c0001], answered one minute later by the location and a report of the placed piece: "Zoom in without moving around to see the top of Samus's head." [metroid/c0002]. It passes the audit. Read another way (the reviewer's error 1, refused): c0002 gives coordinates, so it could be read as a template act (P04) and not a build report. It is cited under building and reporting the mark, and its words report a piece already placed; I keep the build reading. latin c0010 to c0011 fails: in latin the first call and the first build report fall in the same hour (h49.48), and its first line, "Consider me conscripted!", joins rather than calls.
• A02, a start gives the call something to gather around (R01 to P01). Mechanism: a member who proposes or begins a mark gives the room something to answer, and calls gather around it. Fails if: calls come only before any proposal or start. The order fails in 25 of 89 rooms; the failure clause holds in 9. Without joining lines: 63 of 88 (0.716) against 0.568. Bound: where the room calls before anyone proposes, the proposal answers the call (worldoftanks, day9). Sampled and failing: worldoftanks. Transitions: 59 in 27 rooms. Instances, both passing: "I say we make an OG logo and change it to GREENWALL. Anyone down?" [opticgaming/c0191], answered one minute later: "We're all gonna have to come together to get it done." [opticgaming/c0192]; kerbalspaceprogram c0026 to c0028, 37 minutes. Pass 3's instances (sips, habs) answered the start with a joining line, not a call (the reviewer's error 2, accepted).
• A03, a built mark becomes a mark to keep (P03 to P05). Mechanism: once a mark stands on a surface anyone can change, keeping it becomes the work. Fails if: upkeep comes only before any build report. The order fails in 109 of 291 rooms; the failure clause holds in 8. Bound: where the mark was found already placed, or a rival attacked first, upkeep comes first. All four sampled rooms hold. Transitions: 214 in 85 rooms. Instance, passing: "It's done!" [monsterhunter/c0082], answered one minute later by "time for upkeep now" [monsterhunter/c0083]; reddevils c0124 to c0125 also passes.
• A04, keeping the mark brings the room to its neighbours (P05 to P08). Mechanism: keeping a mark against erosion brings the room up against the neighbours whose pixels erode it, and it talks with them. Fails if: border talk comes only before any upkeep. The order fails in 166 of 401 rooms; the failure clause holds in 18. Bound (pass 1): on the late side rooms talk with neighbours first (6 of 15 hold). Bound (pass 2): border talk also comes first where the work was found already placed (unitedkingdom), where a room entered the canvas through another room's offer (yuyuyu), and where neighbours were present from the room's first post (sweden, worldoftanks). Transitions: 293 in 129 rooms. Instances, both passing: "We have to stop this takeover!" [unturned/c0059], answered 53 minutes later: "Maybe we can arrange something with r/rarepuppers to get them to build somewhere else?" [unturned/c0060]; "bmo has been run over by the weird grey bar obsession group!" [adventuretime/c0064], answered: "They are too strong to be beaten through force. Diplomacy is our only option now" [adventuretime/c0065]. Pass 3's switzerland pair invoked a treaty made earlier, and DestinyTheGame fails the order (the reviewer's error 3, accepted in part). switzerland's own order holds: first upkeep h5.38, first treaty talk h18.62. The field (C4): one buffer was negotiated in r/place at hours 5.00 to 7.08 (62mg1j). One episode does not test this count, and the bound for neighbours present from a room's first post already covers it (field-C4.md, list 3, item 5).
• A05, a settled border is a line members keep (P08 to P07). Mechanism: a settled border gives members a line to keep, and they spare the neighbour's work by it. Fails if: sparing comes only before any border talk. The order fails in 52 of 158 rooms; the failure clause holds in 13. Bound: sparing is often tacit and first. Sampled and failing: edmontonoilers, totallynotrobots. Thin. Instance, passing: "Cool, but can you keep the [tiny rick]" [asktransgender/c0003], answered two minutes later: "We have a policy to not harm any artwork" [asktransgender/c0004]. Pass 3 printed one uncited turn, ubc c0084 (the reviewer's error 4, accepted).
• A06, scripts arrive under strain (P05 to P14). Mechanism: upkeep under attack outruns one pixel per interval, and members turn to scripts and spare accounts. Fails if: machine hands come only before any upkeep. The order fails in 43 of 203 rooms; the failure clause holds in 12. Bound: where a room scripted the building from the start; spare accounts can also serve an attack before any upkeep (canucks). Sampled and failing: canucks. Transitions: 117 in 53 rooms. Instance, passing: "We're fighting on several fronts, but this is a war we shall win" [ubc/c0089], answered two minutes later: "I got three accounts going right now, and an overdue essay I'm prioritizing over. We. Cannot. Give. In." [ubc/c0090]; TheFarLeftSide c0384 to c0385 also passes. Pass 3's foxes instance fails check (i): foxes' first machine hands (h69.26) come before its first upkeep (h70.63).
• A07, a finished mark is celebrated together (P03 to P11). Mechanism: a mark reported done gives the room a finished thing to point at, and the room celebrates it. Fails if: celebration comes only before any build report. The order fails in 100 of 282 rooms; the failure clause holds in 4. Bound: where the first mark was found made by others, the room celebrates the find; where hour 73 cut the work unfinished, the room marks the attempt ("We almost did it!" [ultrahardcore/c0212]; a watermark mourned in totallynotrobots). Transitions: 96 in 47 rooms. Instance, passing: suomi c0097 to c0098, "Me teimme sen!", 17 minutes. touhou c0090 to c0129 fails on reading: its second line, "The bomb is already done tho. lol", corrects the first and does not celebrate.
• A08, what is celebrated is recorded (P11 to P12). Mechanism: celebrating the work turns members toward keeping a record of it. Fails if: records come only before any celebration. The order fails in 64 of 289 rooms; the failure clause holds in 11. Bound: on the late side the record often comes first (8 of 15 hold). Transitions: 259 in 108 rooms. Instance, passing: "Place 2017, we did it guys. Good work." [lakers/c0226], answered in one minute by an account of the border [lakers/c0227]. titanfall c0211 to c0212 fails on reading: its first line posts the final image, a record and not a celebration.
• A09, the record is what passes on (P12 to P13). Mechanism: a record of the work gives the room something to carry. Fails if: carrying on comes only before any record. The order fails in 32 of 145 rooms; the failure clause holds in 8. Bound: where a room adopted its mark as an emblem while still building (texans). Sampled and failing: texans. Instance, passing: "Petition to add that image to the subreddit theme." [uiuc/c0155], 46 minutes after the final image [uiuc/c0154]; mexico c0369 to c0370 also passes.
• A10, too few hands, so the room moves (K02 to P10). Mechanism: a room that judges it has too few hands to hold its spot stops fighting for it and moves. Fails if: a move comes with no doubt before it. The order fails in 10 of 21 rooms; the failure clause holds in 3. Bound: where a room moves early by choice; where a late room writes its judgment of too few hands after the move (guatemala, h79.1); where a room inside a coalition moves by the coalition's plan with no doubt of its own (MiamiHurricanes). Sampled and failing: anarcho_capitalism. Thin. Its one transition, paranatural c0020 to c0021, fails check (i): paranatural moved at h38.15, before its doubt at h54.27. The instance is now a holding room's words: "Everyone has given up... Osu is taking over." [fivenightsatfreddys/c0623, h33.55] and, 14 minutes later in the same thread but not as a reply, a proposal "to abandon the effort of keeping the one we have now alive and instead focus on moving it" [fivenightsatfreddys/c0341]. No transition in a holding room passes all six checks.
• A11, a template settles a design argued in a thread (P02 to P04). Mechanism: design talk in a thread is settled by someone posting a template. Recounted on the widened P02: 100 of 166 rooms (0.602) against a 95th percentile of 0.639. Its order between rooms is still at chance, so it is kept as a transition. Sampled and failing: texas, empiredidnothingwrong. Instance, passing: "Maybe make it 20x20? Or just a purple W?" [udub/c0008], answered: "Will update template image and upload here." [udub/c0009]; wallstreetbets c0161 to c0162 also passes.
• A12, the cheapest answer to a call (P01 to P15). Mechanism (from conversation analysis, C3b): A call is the first part of a pair: posted to a thread, it makes an answer from each reader the next thing due. Joining is the answer the call prefers, so it comes bare, one line that commits and gives no reason ('I'm in'); declining is the dispreferred answer and comes with a reason. A bare one-line join is the ordinary way a call is accepted. Stage C2's sentence: A call is answered at the lowest possible cost: one line that commits the member and asks for nothing back. Fails if: The one-line pledges in a room answer no call, or every answer to a call is long and conditional. Or joins answer a call with reasons as often as refusals do, or refusals come as bare as joins. Tested on attack calls only (C3b); on calls to place this clause is not addressed. Never counted as an order. Instance, passing the checks that apply: "LETS CREATE THE DESTINY LOGO IN THE CENTER OF r/Place" [DestinyTheGame/c0002], answered "I'm in" [DestinyTheGame/c0008]. Pass 3's instance, lebanon c0026 to c0027, fails check (iii): its call is cited under building the homeland's flag, which is the mark's content and not a call. pcmasterrace c0904 to c0905 also fails check (iii).
• A13, short of hands, a room turns to other rooms (P05 to P16). Mechanism: a room keeping its work under strain runs short of hands and turns to other rooms for help, and other rooms send it. Fails if: help is traded only before any upkeep. The order fails in 69 of 240 rooms; the failure clause holds in 14. Bound: where a room helps before it has a work of its own, or comes to the canvas as another room's helper. All four sampled rooms hold. Transitions: 106 in 44 rooms. Instance, passing: "I wish people wouldn't keep placing different colored blocks on our letters just to mess with us." [aceattorney/c0049], answered one minute later: "Maybe we should ask the Danganropa subreddit for support." [aceattorney/c0050]; dragonquest c0036 to c0037 also passes. Pass 3's naruto instance fails check (i): naruto's first help (h27.81) comes before its first upkeep (h39.06).
• A14, a settled border opens a channel for help (P08 to P16). Mechanism: talk over a border opens a channel through which the two rooms trade help. Fails if: help is traded only before any border talk. The order fails in 76 of 214 rooms; the failure clause holds in 15. Bound: thin, 0.009 above the null's 95th percentile. All four sampled rooms hold. Transitions: 108 in 44 rooms. Instance, passing: "Hi, I'll be the ambassador for WIT on /r/place, we arent trying to write over you guys." [littlewitchacademia/c0049], answered: "Thank you very much! I'll stick around as often as I can to help maintain your logo :P" [littlewitchacademia/c0051]; sooners c0033 to c0034 also passes. ElSalvador c0006 to c0007 fails check (i).
• A15, a call's hands can turn on a rival (P01 to P09). Mechanism: a call brings members to the canvas, and some turn its hands against a rival's work instead of, or before, building the room's own. Fails if: attack calls come only before any call to place. The order fails in 36 of 129 rooms; the failure clause holds in 7. Without joining lines: 91 of 129 (0.705) against 0.535. Bound: where a room's first canvas act is an attack (edmontonoilers, canucks, anarcho_capitalism), the attack call is the first call. All four sampled rooms hold. Transitions: 34 in 19 rooms. Instance, passing: "me and my roommate are trying to make one in that spot rn if you wanted to join in" [Temple/c0005], answered four minutes later: "Conversely we could aim for right over the Penn State logo" [Temple/c0007]; completeanarchy and stlouis also pass.
• A16, an attack call is refused inside the room (P09 to P07). Mechanism (from conversation analysis, C3b): A call to attack makes an answer from the room due in its thread. Members who do not want the attack refuse it, rein in the attackers or apologise to the target; refusing is the dispreferred answer, so it comes with a reason, and the reason states the room's norm or the attack's cost ('Nah, keep /r/place neutral.'; 'Why? That'll just cause them to want to attack us'). Stage C2's sentence: A call to attack another room's work is answered inside the room: members refuse it, rein in their attackers or apologise to the target. Fails if: In a room, sparing and restraint come only before any attack call, or attack calls draw no refusal. Or refusals of attack calls come as bare as acceptances. Tested (F-014): refusals of attack calls gave a reason in 23 of 38 read pairs, acceptances in 2 of 14; refusals were not longer. The order fails in 22 of 104 rooms; the failure clause holds in 5. Bound: partly constitutive; where sparing is tacit and first (touhou, calgaryflames), restraint comes before any attack call. Sampled and failing: touhou, calgaryflames. Transitions: 127 in 52 rooms. Instances, all three passing: "Wipe out the Dolphins. They're building." [nyjets/c0086], answered in one minute: "Nah, keep /r/place neutral." [nyjets/c0087]; "How about we just work on our own and not be assholes" [leafs/c0240]; "No, stop messing with other schools" [Temple/c0054].
• A17, an attack call is met with a truce (P09 to P08). Mechanism: a call to attack is met by the room's relations with its neighbours: members invoke a truce or propose a deal. Fails if: border talk comes only before any attack call. The order fails in 77 of 172 rooms; the failure clause holds in 17. Bound: early side only; on the late side border talk comes first (0 of 4). Sampled and failing: strangerthings. Transitions: 73 in 35 rooms. Instance, passing: "Let is be us for once who invades! Texas shall fall" [czech/c0151], answered four minutes later: "We [already agreed to a truce here]" [czech/c0153]. PlaceNL c0042 to c0043 and thailand c0162 to c0165 fail check (i): in both rooms border talk comes first.
• A18, an attack is carried on in talk (P09 to P18). Mechanism: an attack makes the rival a named party, and the contest is carried on in taunts, chants, claims of victory and a salute. Fails if: rivalry talk comes only before any attack. The order fails in 12 of 68 rooms; the failure clause holds in 2. Bound: early side only; no late room carries both. All four sampled rooms hold. Transitions: 50 in 14 rooms. Instances, passing: "Help us hijack the WPI r/place!" [rpi/c0024], answered: "Come at us bro" [rpi/c0026]; anarcho_capitalism c0088 to c0089. clg c0040 to c0041 fails check (i): clg's rivalry talk (h12.62) comes before its first attack (h37.54).
• A19, under attack, works join in coalitions (P05 to P17). Mechanism: a room keeping its work against attack joins other rooms whose works face the same threat. Fails if: coalitions come only before any upkeep. Recounted on coalitions alone: 87 of 121 rooms (0.719) against a null mean of 0.614 and a 95th percentile of 0.678. The order fails in 34 of 121 rooms; the failure clause holds in 7. Bound: on the late side no room of 4 holds, since late rooms enter the canvas through other rooms (bretagne, MiamiHurricanes, yuyuyu); thin. Sampled and failing: lakers (pass 4), bretagne. Transitions: 52 in 28 rooms (pass 2's count, on the element with hosting). Instance, passing: "Now we get to defend it" [criticalrole/c0057], answered four minutes later: "hopefully those friendly folks at RWBY and the Bold and Brash people help on occasion" [criticalrole/c0058]. Pass 3's naruto instance fails check (i): naruto joined a coalition (h32.15) before any upkeep (h39.06). yugioh c0107 to c0110 fails check (iii): its second line is a host's ruling, which left the coalition element with the recut.
• A20, the calls fill the host sub, and the sub draws a line (P01 to P20). Mechanism: calls to the canvas flood the host sub, and its moderators or members answer by drawing a line around canvas talk: one thread, removals, a canvas sub. Fails if: the line comes before any call, or the line's words name no canvas flood. The order fails in 23 of 155 rooms, of three kinds: the sub's automatic rules remove the first call as it is posted (9 rooms, three in the same hour); a canvas sub or megathread is set up before the host carries any call (7); members dismiss the canvas or object to other rooms' canvas posts before the room calls (7). The failure clause's first half holds in 5. By actor, while the canvas runs (before hour 73): the calls come before the host sub's rulings (megathreads, removals, a canvas sub, disowning the work, pausing events, new posting rules) in 102 of 118 rooms (0.864, 95th percentile 0.644), and before members' objections (to the flood, or to the canvas's worth) in 57 of 64 (0.891, 95th percentile 0.688). Both beat the null, so by the rule written first A20 stands on the whole line: 122 of 144 rooms before hour 73 (0.847, 95th percentile 0.618). Without joining lines: 129 of 154 (0.838) against 0.584. The mechanism fails in transformers: the order holds there, but its first line, at h80.40 after the close, is a member's judgment of the canvas's worth and names no flood (the reviewer's error 5, accepted). Bound: partly constitutive; the three paths above; and a judgment of the canvas's worth after the close, which answers no flood. Transitions: 29 in 22 rooms. Instances, all three passing: "Help build a Mario in /r/place!" [nintendo/c0120], answered 17 minutes later: "Maybe want to go to the /r/place Megathread where we're trying to build a Mario... slowly..." [nintendo/c0121]; "Can we just stop posting about r/place please? It's becoming just spam at this point" [rocketleague/c0722]; "N'y a t il pas de super poteau pour cette requête?" [france/c0444].

Tentative entries from the field (stage C4)

These entries came from the field, not from my rooms. Each is a hypothesis. Stage D sends it to every room, marked tentative and with no word of where it came from, and each room says from its own record whether it shows its side, contradicts it, or says nothing. None is counted, and none enters the counts above.

• P21, process (tentative, from the field). Members dispute who may commit the room to an agreement with other rooms: they say that one member's agreement does not bind every placer, deny that a treaty speaks for them, or ask another group for a leader to deal with. Range: from one member saying that a deal cannot stop everyone to a treaty announced in r/place answered 'You don't speak for me, man.'. Sits under T3-126. Level: between rooms; a room shows its side in its own members' talk. The field's mark: firm: the disclaimers, the denial and the request for a group leader are public exchanges; provisional: that an agreement or coalition prompts the dispute. Field support: r/place 62mg1j c60256; r/place 62mg1j c60257; r/place 62mg1j c60265; r/place 62qib1 c720095; r/place 62qib1 c720105; r/place 62qib1 c720108; r/place 62qib1 c720109. Room side found so far: flyers:c0166, flyers:c0169.
• P22, process (tentative, from the field). After placement ends, members contest which version of the canvas and of the event is kept: they ask a cleanup of a shared copy to fix their work, take part in it, argue that the cleanup should keep the damage as history, and correct accounts of the event that describe their group wrongly. Range: from one member asking that a logo be cleaned in a shared copy to a room arguing that its scars are its history. Sits under T4-027. Level: the event (a shared copy and public histories of the whole canvas); a room shows its side in its own members' talk after hour 73. The field's mark: firm: the sector instructions, the question of who decides, the retention decision, the objection to sterilising history and the correction promised are public exchanges; provisional: that preserving a shared object requires negotiating its legitimate version; the execution of the cleanup is not observed. Field support: r/place 63f0qb c3920184; r/place 63f0qb c3920185; r/place 63f0qb c3920186; r/place 63f0qb c3920193; r/place 63e1pb c3910162; r/place 63e1pb c3910163; r/place 63b6md c3850139; r/place 63b6md c3850142. Room side found so far: AMD:c0435, SquareSpiral:c0217, strangerthings:c0145.
• A21, P08 to P21 (tentative, from the field). Connection: in a room carrying both, the first agreement with another room (a border, a truce or a deal) comes before the first dispute over who may commit the room. Mechanism: An agreement made with another room in the room's name puts its members' compliance in question. Members who did not make it say that it does not bind them, or that no one can bind every placer, and the other side asks who can speak for the group. Fails if: In a room carrying both, the dispute over who may commit the room comes only before any agreement with another room, or the dispute answers no agreement. Level: between rooms; the order is counted inside each room's record. The field's mark: provisional: 'a protective coalition claim prompts participants to examine who can commit a group' (field/model.md, process 4); the field's instance is a protective treaty, which my model would place under deals (P08) or coalitions (P17). Field support: r/place 62mg1j c60256; r/place 62mg1j c60257; r/place 62mg1j c60265; r/place 62qib1 c720095; r/place 62qib1 c720105; r/place 62qib1 c720108; r/place 62qib1 c720109; r/place 62qib1 (a treaty announced between major factions). Room side found so far: flyers:c0166, flyers:c0169.

Theorised arrows, and the model with and without them

No arrow rests on my reading alone. Two arrows do not rest on an order count that beats a shuffle, and they are listed apart as theorised:

• A11: its order across rooms is at chance, at pass 4 as at pass 3, and it stands on transitions inside threads only.
• A12: never counted, on exemplars only. Since C3b its mechanism is conversation analysis's, tested on attack calls and not on calls to place.

Four more are counted and beat the null, but thinly: A05, A10, A14 and A19. A10 now rests on quotes alone, since its one transition fails the audit.

Without the two theorised arrows, the model can no longer say how a room settles a design under argument, or why calls are cheap to answer.

Without all six weak arrows, the model keeps the spine (A02, A01, A03, A04, A06), the host's line (A20), exchange under strain (A13), the contest (A15, A16, A17, A18) and the close (A07, A08, A09). It loses why rooms with neighbours mostly do not fight (A05), what sends a room back (A10), help traded along a border (A14), and coalitions (A19). The second of the four things then has no counted answer.

The model on the dimensions

The next table gives, per dimension, the mass of coded turns answering coded turns across the dimension's boundary (c2_dim_mass-p4.txt). Rooms are beside each count. The last three columns drop every transition touching a double. Of 56,071 transitions with both ends placed, 31,636 touch no double. The masses changed at pass 4 for Coordination without command and Collective identity only, because the land's flag and emblems moved from the second to the first. The hosting recut stayed inside Order without law.

The next table states the arrows at the dimension level. Each row names the arrows beneath it, a mechanism written at that level, the observation that would show it failed, the strongest instance beneath that passes the audit, and the transition mass from the first dimension to the second.

Pass 3's table printed sips c0026 to c0027 for the second row and naruto c0144 to c0145 for the fourth. The first is a joining line (the reviewer's error 2). The second fails the audit's check (i).

One cross-dimension arrow is reported as mass, not as a dimension-level arrow. A10 runs from Critical mass to Order without law, but it rests on 21 rooms, against a mass of 1,257 transitions of other traffic. A12 runs from Critical mass to a form-pass element outside the dimensions. A05 and A14 lie inside Order without law, A08 and A09 inside Imprinting, A11 inside Coordination without command, and A18 inside Contention.

What the arrows and masses show:

• Contention is not residue. One arrow runs in (from Critical mass) and two run out (to Order without law). Its masses are close to balanced (407 in, 309 out, without doubles). The contest is fed by mobilized hands and answered by the order between rooms.
• Order without law draws in about twice what it sends (1,776 against 892 without doubles). Six arrows run into it from other dimensions (A04, A13 and A19 from Maintenance, A10 from Critical mass, A16 and A17 from Contention) and none out, so it is residue: the model ends there.
• Imprinting is residue too: A07 runs in and nothing runs out. Its masses say otherwise: 1,121 transitions go into Maintenance and 1,298 into Order without law, since "we did it" posts are answered by repair and border talk (see the ungrounded relationships).
• Host framing is almost all internal (6,839 against 226 out, without doubles). One arrow runs in (A20, from Critical mass) and none out, so it is residue: the host's line answers the calls, and no arrow says what the line does to the room's work. Finding F-009 says the play frame does not delay the canvas work across rooms.
• Collective identity carries no arrow. Its candidates failed: the quarrel carried in on 9 rooms, and membership carried in on 145 rooms at pass 3 and on 126 after the flag and emblems left it (F-011). With those two themes gone, its in-mass without doubles fell from 565 to 461 and its out-mass from 643 to 245.

Dynamics

• Loops. None is grounded. A within-room loop needs one room's dated chain to run the whole cycle. Passes 4 and 5 add no arrow, so no loop can close. The contest runs from calls to attack to restraint or truce, and nothing grounded runs from restraint or truce back to a call. The move-and-rebuild candidate (loss, move, build, keep) still lacks an arrow from the move to building that beats its base rate. model/loops.jsonl is empty.
• What returns a room to a state it had left: a loss. The room goes back to choosing a spot and cutting its design to what can survive. Its calls fall from the crisis before the move, but it keeps calling more than rooms that did not move (F-002, bounded).
• What is irreversible across hour 73: placement stops. Calls to place, building, upkeep, machine hands, attacks, help traded in pixels and deals over pixels end with it. After hour 73 a room can celebrate, record and carry on (A07, A08, A09), call for a later canvas, judge the canvas's worth, and keep a rivalry going in talk (victory claims, salutes, blame after the close). Its organizing of placement on this canvas is over. Organizing around the canvas's records and copies goes on after it (P12, P13; the tentative P22; field-C4.md, list 3, item 1).
• Dating by the hour of the post (C4). Each order count dates a concept by the hour of its post. A retrospective report posted late does not date the act it reports. Because the counts compare first concepts, such a report moves an element's first hour only when it is the room's only concept of that element (field-C4.md, list 3, item 6).

Ungrounded relationships

These relations have a count and no mechanism I have stated and tested. They are correlations, in_model false by definition, listed so that stage C5 can mark anything that rests on them. Counts are from mem.py pairs and c2_dim_mass-p4.txt.

• Completion ritual answered by repair work: 1,167 transitions in 274 rooms (fourth-order ledger).
• Completion ritual answered by border talk: 805 transitions in 221 rooms.
• Coordination without command into Order without law: 3,196 transitions, the largest cross-dimension mass, and 1,975 back.
• Imprinting into Order without law: 1,298 transitions.
• Collective identity into Order without law: 441 transitions (848 at pass 3, before the flag and emblems left Collective identity).
• Order without law into Contention: 598 transitions. Deals broken may turn into attacks; no arrow from talk to attack was tested.
• Membership carried in, then hosting (K04 to P19, pass 3): 21 of 28 rooms (0.750 against a 95th percentile of 0.714). Its declared mechanism (guests come to the body's mark) shows in 5 of the 21 rooms. 16 show the reverse role: a room asks a host for space after laying its own mark (c2_first_concepts-K04-P19-p3.txt). Not in the model, and not recounted on the narrowed K04.
• Hosting, then coalition: 12 of 17 rooms carrying both put hosting first (pass 3). The reverse of a declared test, not declared and not tested.
• Attack, then membership carried in (pass 4): on the narrowed K04 the first attack comes first, or in the same hour, in 74 of 126 rooms. The reverse of a declared test, not declared and not tested.

Looked for and not found

Each of these was tested and not grounded. They are results (rule 8).

Pass 1:

• Attribution as the hinge between restraint and contention. P06 to P07 holds in 0.452 of rooms against a null mean of 0.456. P06 to P09 holds in 0.194 against 0.408, reversed.
• A room under attack, then repair or a move. P09 to P05 holds in 0.444 against a 95th percentile of 0.449. P09 to P10 holds in 0.561 against 0.610.
• Doubt, then calls. K02 to P01 holds in 0.175 against 0.352, reversed.
• Machine hands, then upkeep. P14 to P05 holds in 0.202 against 0.375, reversed.
• Emblem before template, as an order between rooms: at chance.

Pass 2:

• Exchange, then sparing. P16 to P07 holds in 0.427 against 0.494.
• Border talk, then coalition. P08 to P17 holds in 0.632 against a 95th percentile of 0.654.
• Exchange, then coalition. P16 to P17 holds in 0.384 against 0.450.
• A quarrel carried in, then attack. K03 to P09 holds in 2 of 9 rooms.
• Attack, then the room's own building. P09 to P03 holds in 0.385 against 0.469, reversed: rooms build first.
• The play frame delaying the canvas work. 59 frame-filled rooms start at a median h21.80, against h20.25 for 275 others (p 0.43; F-009).
• A move stopping the room's calls. A move lowers calling from the crisis before it, but not below other rooms (F-002, bounded; c2_relocation_window-p2.txt).

Pass 3:

• Membership carried in, then attack. K04 to P09 holds in 0.593 of 145 rooms against a 95th percentile of 0.634 (F-011).
• Exchange, then hosting. P16 to P19 holds in 0.379 of 29 rooms against 0.552.
• Coalition, then hosting. Coalitions without hosting, then P19, holds in 0.294 of 17 rooms, below the null mean of 0.451.
• Upkeep, then hosting. P05 to P19 holds in 0.635 of 52 rooms against 0.654.
• A host admitting guests by fit with the body it carried in. Of 23 cited rulings that give a ground, 6 give fit with the nation, colour or theme, 12 give space or design, and 5 give ties (c2_vetting_tally-p3.txt; F-012).

Pass 4 (c2_arrow_evidence-p4a.txt):

• Border talk, then coalition, on coalitions alone. P08 to P17 holds in 74 of 109 rooms (0.679), at the 95th percentile of 0.679 and not above it.
• Exchange, then coalition, on coalitions alone. P16 to P17 holds in 31 of 79 rooms (0.392) against 0.570.
• Border talk, then hosting. P08 to P19 holds in 22 of 39 rooms (0.564), below the null mean of 0.604.
• Membership carried in, narrowed, then attack. K04 to P09 holds in 52 of 126 rooms (0.413), below the null mean of 0.532 (F-011).
• The design before the template, on the widened P02. P02 to P04 holds in 100 of 166 rooms (0.602) against 0.639: still at chance (A11).
• The call's boundary with one-line joining, as a change to any arrow. With the joining lines stripped out, no arrow from the call changes its beaten status (c2_arrow_evidence-p4c.txt). P01 holds some joining lines the coders placed with calls, and the boundary is reported as read, not recut.

Pass 5: no test was run. By J's ruling on QC2-002, membership naming the rival in the same turn as the attack is carried as a claim (C02), untested for order.

The tiers the arrows run between, and what the model does not use

Most arrows join two elements tied to fourth-order themes. A02 runs from a pair of third-order themes (R01) to a fourth-order theme. A10 runs from a fourth-order theme to a pair of third-order themes (P10). A12 runs to a form-pass finding (P15). Five standing elements carry no arrow: P06, K01, C01, C02 and R02.

At pass 5 the script's rule counts 41 of 197 unused (c2_unused_t3-p5.md). The rule lets a standing element use every member of its fourth-order themes, so C02 takes up Frame bridging and Flagging the nation. C02 uses them only as the words of a tie in an attack turn, untested for order, and nothing else in the model uses them. I report both counts: 41 with C02 and 55 without it. The next list is the 55, as pass 4 left it.

The next list gives the 55 of 197 third-order themes the model does not use without C02 (c2_unused_t3-p4.md; 53 at pass 3), grouped by fourth-order theme. The two pass 4 recuts changed the list. The four hosting themes, now in Territoriality, are unused while P19 is a candidate. The land's flag and emblems are now used, through P02. K04's members are listed as unused, since K04 is a candidate.

What was dropped, and which of the five it failed. The five are the concept and the contract's four things. Each item below was considered as an element and left out, because at pass 4 the model says nothing different about any of the five without it.

• Sensemaking would bear on becoming able to act. No arrow was formed.
• Frame bridging, Flagging the nation and Neo-tribes would bear on becoming able to act and on what followed, as membership carried in. Tested as one condition (K04) at pass 3 and again, narrowed, at pass 4: it does not come before the attack more than chance, and at pass 4 it falls below the null mean. Its count before hosting rests on the reverse of its declared mechanism. The quarrel carried in alone failed at pass 2.
• Symbolic boundaries would bear on settling what to act on (which symbols may be drawn). Left out of K04 by declaration; no arrow was formed.
• Hosting (four members of Territoriality from pass 4) would bear on what followed between rooms. Tested as P19: it follows neither exchange, coalition, upkeep (pass 3) nor border talk (pass 4).
• Backstage decision-making would bear on settling what to act on. Chat decisions reach the record only as announcements.
• Visibility returns would bear on what is left behind. No arrow was formed. The reviewer set recruiting canvas visitors and drawing lapsed fans back beside the call. It was to be considered only if P01 were recut at its boundary with joining, and P01 was not recut. At pass 5 it is the residue of six story rooms: scp, carried from pass 4, and five of the 11 fresh rooms (parahumans, TheAdventuresofTintin, shishamo, hunterxhunter, luciomains). In them the mark brings readers to the sub or back to the topic, and the room talks about the newcomers. The story says it is one room's residue; at pass 5 it is six rooms'. No element was added, because the pattern showed only during the reading and no test was declared for it. It is material for the next stage.

Where the model should break, in its own terms

• Rooms whose canvas work is one thread (ultrahardcore): the spine collapses into one exchange, and the model can still tell it (below).
• Rooms where a starter places alone and no one answers: R01 with no P01.
• Bag rooms (greenlattice t03), where many acts between rooms each carry a few concepts: P07, P08, P09, P16 and P17 cannot be told apart there.
• Late rooms that enter the canvas through other rooms (bounds on A04, A17, A19): there the order between rooms comes before the room's own work.
• Rooms that host other rooms' works on their own mark (sweden, catalunya, smashbros, placeDE, greenlattice, orderofthebluecorner, purplecorner, among the pass 3 story rooms). From pass 4 hosting is a claim on space inside Territoriality, and P17 no longer holds it as a coalition. P19 is a candidate with no grounded arrow, so the model can tell a host's claim on its spot, not its rulings on guests. From pass 5 this is stated as a boundary at the return, for hosts with readers before the canvas and without. The vote or form that decided each guest is decided order, which the model counts as rare.
• Colour factions the canvas gathered (greenlattice, purplecorner, orderofthebluecorner, thebluecorner; a boundary at the return from pass 5). Their faith names their rivals: 5 turns in 3 of these rooms pass C02's three checks with a colour as the tie, for example "We need to attack back. Blue the Purple Corner!" [thebluecorner/c0230]. Their faith also rules on guests, by vote and by fit with the colour, and splits the faction over doctrine: art on a coloured backdrop against a pure corner. The model tells their steps from their first post, not their faith, and C02 does not reach them, since a colour faith is not a tie from before the canvas.
• Rooms with no posts in the week before the canvas (78 of 705). An empty week does not show that the canvas founded a room: side subs, quiet subs and bodies the canvas gathered all have one. The six hosts whose rulings are coded as vetting are all among them, but hosts with readers before the canvas (sweden, catalunya, smashbros) rule on guests too. The pass 3 rooms of this kind (rainbowgrid, pgang, placecanada, CKCrusaders, purplecorner, greenlattice, orderofthebluecorner) run the story's steps from their first post. What three of them do after it, as hosts ruling on guests and as colour faiths naming a rival, the model does not reach.
• Rooms whose answers the coders dropped: the enrolment and many replies are not in the record.

The three strongest arrows, read as artefacts

The three are chosen by the gap between share and null mean: A20 (0.314), A16 (0.259) and A01 (0.254). For each, the argument is that the order comes from which turns the coders chose to code and how they labelled them.

• A20. A removal, a pointer to the megathread or an objection to the flood is coded as such only when there is a canvas post to remove, point or object to, so the line would follow the first call by definition. What separates it from a pure artefact: P20 also holds acts that need no call in the host sub (opening a canvas sub, arguing the canvas's worth), and 23 rooms draw the line first. In 22 rooms a line by another member or a moderator replies to a specific call in the same thread within minutes (29 transitions). Counted by actor while the canvas runs, both the host sub's rulings and members' objections follow the calls. transformers shows the artefact's edge: a judgment of the canvas's worth after the close follows the calls in order and answers none of them.
• A16. A refusal is coded as reining in an attacker only when there is an attack call to refuse, so restraint would follow attack by definition. What separates it from a pure artefact: P07 also holds tacit sparing and apologies, which need no prior call, and 22 rooms spare first. In 52 rooms a refusal by another member replies to a specific attack call in the same thread, within minutes (127 transitions). All three printed instances pass the audit.
• A01. A call is usually a submission title, the first turn of its thread, and build reports are comments under it. What separates: the null keeps each room's coded turns and hours fixed, so the choice of turns is held constant. In 53 rooms the order fails, and in 8 no build report comes after the first call. 70 rooms have a build report replying to a call (164 transitions). With the joining lines stripped out of the call, the order still holds in 132 of 189 rooms.

Two tests

Every element has a range. See the elements table.

The odd room: ultrahardcore, read again whole at pass 4 against the pass 4 model. The April Fools frame (K01) filled the room from h7.65 to h40: 193 of its 212 coded items fall before h40, and only a question about the canvas at h40 touches it. The offensive posts coded under ethnic jokes belong to the frame's licence and claim no nation, so the narrowed K04 does not reach them. The moderators' play with their own powers belongs to the frame; the host sub drew no line around canvas talk, so A20 does not fire. Across rooms the frame does not delay the canvas work (F-009), so ultrahardcore's late start is the room's own, inside the frame. At h57.58 a starter asked for a design (R01). Within half an hour the thread had a proposal (P02), a template, a spot and an order: "Make it completely red first." [ultrahardcore/c0209] (A11). Building followed (P03). There was no second call, no neighbour, no help from another room, no coalition, no host and no contest, so A03, A04, A13, A15 and A19 never fired. At the close the room marked an attempt cut short ("We almost did it!" [ultrahardcore/c0212]; A07's bound) and recounted it (P12). The model tells it as a late, compressed spine that the clock cut before upkeep. What it cannot say is why this room, inside a frame that does not delay most rooms, came so late.

ultrahardcore at pass 5, read again whole against the pass 5 model and story: told. The pass 4 reading above missed one short exchange. The thread first proposed taking over other works' hearts: "Let's take over some of the hearts" [ultrahardcore/c0203] at h57.91 (A15). Five minutes later a member spared one: "Maybe not that heart, since it was the first heart made on /r/place and people want to keep it blank." [ultrahardcore/c0206] (A16). The thread then turned to an outer heart (c0207). So the contest did fire, inside one thread and within minutes of the start, and was answered inside the room. No tie from before the canvas names the target, so C02 does not reach it, and the frame's offensive posts claim no nation, so K04 does not either.
