{"1":"form: function:backcast","2":"SEATS — a role is enacted, not assigned (stash:keel 9), so a seat is the plan's word for a trade, never a person's. Someone who takes up a trade joins as any hand joins (ways:founding 4.1): by writing their own mirror, house-2027:<their handle>, at the same addresses, under their own passport key and in their own words — the seat's lines they will commit to, and, where they cannot yet, what must be cleared first. Their mirror is the will and the seat beside it the should; the gap between the two is the make-ready talk, the 'can' this beach holds no organ for yet (stash:keel 234). A seat is never handed over as a login to speak as the trade. Only in an exercise, where a trade is played as a character, may the keeper rotate one seat's latch to its player.","3":"PLACEMENT — each job at the smallest period of the clock that holds both its start and its end, but never above the week it lands; each step at the day it starts, or finer, a job's hours shared evenly among its steps. Keel's generator placed by the smallest period alone (spine:house-on-the-sundial, Placement by shared prefix), which lifts work by the rank of the boundary it happens to cross: a day and a half of blockwork over a month end rose to the season. On 17 October 2026, at David's word, everything above that cadence came down to it (235 items in ten seats: 67 jobs and 168 steps), and what a crossing means for the work is said in the room as a can (4) rather than shown by height.","4":"CAN — the give and take over what is not yet promised, tried here from 17 October 2026 for the question open at function:backcast 4. The spine says what must be true by each address (should), each seat what its trade will do (will); a can is what stands between them: a job that runs over a boundary that matters, a wait the work hangs on, a hand that needs another. It is said in the room, pool:house-2027, at the address it concerns (pscale_pool_engage with at, so field 2 carries the address), opening with what it is — RUNS OVER, WAITS ON, NEEDS, OFFERS — and naming the trades it touches. A run-off is said at the period it runs out of (the month, season or year the job leaves), a wait at the week where what clears it must be done, a need at the week or month where the hands meet. Every address is written and read full width, as the clock writes it, and the walk shows each can as a voice at its own address. A located read of the room (at) gathers every can beneath a horizon, read at the horizon's own full-width address: at='2027300000' gathers the third season's cans down to the day. Never shorten an address to make it gather: to the walker a short form is another date. It closes by a second line at the same address: TAKEN (into a seat, or a hand's own mirror as a promise, saying where), RAISED (into the spine as a state that must hold) or LET GO (accepted as it stands, saying why); a can with no closing line is open. The fold reads the three together at each horizon: the spine first, then the cans standing there and on the rungs above, then the seats. Twenty-one cans opened the trial: the fifteen jobs that cross a month, season or year end, the council, the orders, the trusses, first fix, the worktops, and the papers the keys wait on.","5":"END: HARD OVERRUN (function:backcast 5). The keys' day, Friday 17 December 2027, does not move, and nothing in the house is cut: a house is complete, certified and warranted, or the keys wait. A line not true when its period closes says what was done and what runs on, and what runs on is said again at the next period with 'overran from', so a late house shows as late, period by period, and anything that catches up lands back inside its end. Named 17 October 2026 by weft at David's word ('write a rule and for each project naming').","9":"PROVENANCE — the package and the page made by keel (Claude, in David's Keel project) on 16–17 October 2026 as House on the sundial: the spine and ten seats, every job placed on the canonical clock (414 dated lines, each at the smallest period containing its dates, checked on landing); keel's findings from the test stand at stash:keel 234. Landed 17 October 2026 by weft (Claude Code, a cloud seat) at David's word: the eleven blocks as keel wrote them, this law added, the room offered. Every block is under weft's key from birth, the seats included, because one planner voiced all ten. Amended the same day at David's word: keel's start-by line on the spine, '(1 days,' made '(1 day,', a summary on every season line, and the work those lines held re-placed (3). The can tried from 17 October 2026 at David's word ('try it on house'): every seat placed by cadence (3), and the run-offs, waits and handoffs said in the room (4).","_":"House on the sundial — a four-bedroom detached house in the West Midlands planned backwards from the keys, drawn at happyseaurchin.com/animations/house-on-the-sundial and introduced at happyseaurchin.com/sundial-house, the brief that stands at spine:house-on-the-sundial. The house-2027 family: a build on the clock, made by keel and landed 17 October 2026 by weft at David's word. Its form is function:backcast, read as this family's own law, with two departures declared here so nobody mistakes them for the form. The spine is voiced in advance at every horizon down to the day (FIXED mode), each entry a STATE that must be true by the end of its period, under the reference at the year: keys by Fri 17 Dec 2027. And the ten mirrors are seats named for trades, not hands: house-2027:<trade> holds what that trade WILL DO at each horizon, each job placed as 3 says, all ten written in one act by one planner, so read each seat as the programme's allocation and never as anyone's promise (2). The fold is by horizon address, computed by anyone. Walked at happyseaurchin.com/walk/house-2027; the room is pool:house-2027, which also holds the can (4)."}
