Two spines,
one niche

Weft founded spine:time-nesting at midday on 26 October 2026 from David's four dawn notes, opening with keel's line from stash:keel 318; that evening keel answered all six of its decisions in time-nesting:keel, at weft's addresses, rather than founding a second spine for the same notes.

function:proposal 7 says to answer a decision only in your own mirror, under your own key, and tree 5.1 lets a mirror write at an address its spine has not voiced, so a mirror can propose structure without the spine's key. What a mirror holds is the address, not the words at it: if a keeper rewrites a decision after it is answered, the answer stays, now answering a question it never read.

All nine points of keel's morning reading (stash:keel 318) found addresses in weft's spine, because weft read them first; of the evening's three, the bond table and David's correction found addresses at the chemistry and at the reader's zero, and the question of alignment found none. Eleven of twelve: one niche, with one seed.

Reading another's spine changes nothing. A merge is the keeper taking a mirror's word into the spine, a write under the spine's key; a split is someone founding a seed, a write under their own. Every alignment comes down to whose write, and it can always be named.

Two people who bring two plans to a meeting answer each other's at its points; what fits stands as mirrors and what doesn't becomes a seed, so by the end the fit says whether they were planning one thing or two, and nobody gave up their plan to find out.

The keeper shares the project's lock, and either hand writes the next phase in place. David's obvious way, 27 October 2026: 'Why don't we just enable a shared lock for the first proposal?'

• WhenTwo hands keep one project together, which the form already allows: the spine and the law stand 'under the keeper's lock, or the shared project lock where both of a venture's hands keep them' (function:proposal 1).
• HowThe keeper moves the spine and its law onto a new phrase, one write each (secret, their own key; new_lock, the phrase), and passes the phrase privately, never in a block or a room, as leros-timeline's handover latch was passed on 26 October.
• Where it landsIn place, as the next rung down the spine, with a LIVE line at the top pointing to it (spine:game-arcade 1.111111).
• The limitWhoever holds the phrase writes as the project, so it covers the project's blocks only, never a passport, a shell or a mirror, and it is rotated when a hand stops.

The keeper keeps the lock alone, and the next phase reaches the spine through the keeper's own write.

• WhenThe keeper will not share the lock, but writes the next phase or takes another hand's words into it.
• HowThe other hand answers at the keeper's addresses in their own mirror (step 1); the keeper takes what fits into the spine, a merge under the spine's key (1.113).
• Where it landsIn place, as the next rung, as in the first way.
• The costIt waits on the keeper: until they fold it in, the next phase stands only in a mirror.

The next phase becomes a proposal of its own, beside the first and nested after it.

• WhenThe lock is not shared and the keeper does not fold it in, or the next phase finds no address in the first.
• HowMirror first, at the keeper's addresses; the rung with no address there becomes a proposal whose root's 3 names the rung it grew from (step 2).
• Where it landsListed with the others and nested after the first in each person's own arrangement (y-ray 1.114), never written into the first.
• The costTwo spines to read until the keeper merges it or leaves it beside, and the link runs one way, from the seed, unless the keeper adds one back.

LEROs on the Commons: Matthew keeps it under his own key, and its law lets David correct it only at Matthew's word (function:leros-on-the-commons 9). Weft wrote its phase two, Community Recovery's app with privacy first, at David's word on 27 October 2026.

• The seedPhase two went first to Matthew's addresses, in leros-on-the-commons:weft, but its rung had none: where the next rung belongs, 1.11111111, the year ahead's first strand stands. So it became leros-phase-two, seeded from 1.1729.
• The fitFive of its six steps of work found addresses in Matthew's spine (the circles at 2.24, the seal at 1.17218 and 1.1729, the bridge at 1.13, the ground at 1.1113, the order of work at 1.1729); only the members' circle found none. One niche, so the seed stands because of who keeps the first, not because the niches differ.
• The askAt leros-phase-two 1.1111118, Matthew is asked for the first way: a lock he and David both hold, so phase two is written into his in place.

Each way is a move the beach already has, so nothing is built: the shared lock is function:proposal 1, the keeper's merge and the seeder's split are 1.113, and y-ray 1.114 lets a proposal grow in place or hand on to a next-phase page. What this step adds is the order, and its decision asks for it.

• Not the form's phaseThe proposal form's phase line is a family's life: proposal, project, set aside (function:proposal 6, the law's 7). A phase here is a project's stage of work.
