2026-10-31 — The product thinker ruled on 2026-10-31, on iss-2610311224444576, that an issue's reservation is narrowed at the source: reserving an issue lane holds its found_at and the paths its fix changes, and a reservation made by hand keeps the footprint it names. The technical facilitator settled one point after the review pair read the ruling: the lane widens its hold before it edits a further path and backs off a live hold another copy has there, because widening after the edit would find the clash only once the work is done. Found after the ruling: `abcd build <iss-N>` and the drain already reserve an issue's found_at alone but do not yet widen to the further paths a fix edits, and the 35-path hold iss-2610311224444576 records carries no run stage, so it was made by hand; this ruling does not reach it, and how a hand reservation wider than its record is treated goes back to the product thinker. Rejected: flagging an over-wide hold while leaving it in force, since builds stay blocked; and lapsing a hold with no run stage sooner, since a paused holder would lose its cover.

• dcn-26103115390248482026-10-31 — The product thinker ruled on 2026-10-31, answering the question dcn-2610311251002713 sent back on iss-2610311224444576, that work on an issue or an intent is reserved only by a build or a drain: a fix that would be done by hand starts through abcd build instead, which holds an issue's found_at (an intent's, its spec's footprint) and, once iss-2610311224444576 builds it, widens an issue lane's hold file by file before each further edit, backing off a live hold another copy has there. The hand reservation of an issue or an intent is removed, but only after that widening ships, so a fix that edits beyond its found_at is never left with no way to hold the file (iss-2610311539091723); a release's reservation, and releasing a hold, stay. Accepted costs: an issue needs a found_at and an intent a READY spec before any work starts, a small fix runs the whole loop, and someone working outside abcd has no way left to mark work as taken. Rejected: keeping hand reservations, since one wide hold stalled nine of thirteen chosen builds on 2026-10-31.
• dcn-26103115443253972026-10-31 — The person, as technical facilitator, chose on 2026-10-31 how an issue lane widens its hold before it edits a path beyond its reservation (iss-2610311224444576, refining dcn-2610311251002713): the implementer runs abcd implement widen, naming the lane and each further path, before its first edit there; the step reserves the issue again with the held footprint and those paths, judged for overlap like any reservation, and exits 3 with nothing changed when another copy holds a live reservation on one, so that file is not edited and the implementer stops without a receipt, the implement stage handing the lane out again on a later step. As the backstop, an implementer's receipt is refused while the lane's branch changes a path its reservation does not cover, naming the paths and the widen step, which catches a forgotten call and an edit made through the shell. A lane leaving its landing for a fresh round keeps the paths it widened to beside its found_at. Rejected: a hook on the host's file tools as the control, since it reaches origin on every edit, fails offline, does not run on a host without hooks and misses edits made through the shell; and widening only at the receipt, which finds a clash after the work is done.
• iss-2610311224444576On 2026-10-31 nine of thirteen intent builds the product thinker chose were refused at the reservation check by one hold: iss-2610252214522207, whose found_at is the single file internal/core/surface/examples.go, holds a live reservation on origin until 2026-10-31T18:42:23Z whose footprint names dozens of paths (brief chapters 01-product, 02-constraints and 04-surfaces, commands/*.md among them) and which carries no run stage, unlike the build lanes beside it. A hold many times wider than its record's own scope, kept for hours with no lane showing progress, starves every autonomous build that touches the brief or the command pages, and nothing flags it: abcd peers lists it like any other live hold.
