2026-10-16 — A plain release keeps a hand-back that still stands (facilitator-on-delegation, drain-many-accounts review round): a release with no hand-back of its own reads the reservation branch's first-parent line below its tip, at most 256 commits, to the first tombstone, and when that tombstone marks a hand-back whose record origin's default branch holds unchanged by the reading handBackStands uses, the new tombstone carries its kind and blob forward and the result says so (Result.HandBackKept); the walk passes renewals and take-overs, and an unreadable commit, a plain tombstone, the root or the bound keep nothing. The carried tombstone names the person releasing as its holder, since the closed trailer form names no earlier holder and a new trailer would read as unreadable to every binary already released. A release asked to hand back over a tip a plain tombstone already released publishes the hand-back as that tombstone's child, fenced by Tip on the tombstone or the reservation it released; with HandBackBlob it publishes none once the record's blob is another. Reserving and releasing an issue is not a person's change to its record, and a failed build start's clean-up is not a person's decision, so neither erases the hand-back (grounds: dcn-2610161040365515, dcn-2610161412283450; spc-2610161044461448 step 3; the review of steps 1 to 18).

• dcn-26101610403655152026-10-16 — A drain's hand-backs are published on origin (facilitator-on-delegation, drain-many-accounts): a drain's hand-back, from a lane or from a judgement, is the release of the reservation the drain took before judging, carrying a closed-vocabulary hand-back kind and the blob id of the issue record on origin's default branch, never free text; a reservation a drain makes backs off such a tip while the blob is unchanged, while a person's own abcd reserve or abcd build is let through with a note; a promotion the checkout cannot make because it does not hold the record as origin does publishes the tombstone alone and says so; an issue whose related_intents names an intent is ineligible, a clause added to brief invariant 19; and every account draining at once runs one build, since an older build reads the tombstone as a plain release (grounds: reasoned tombstones as Cassandra and Kafka keep them, and the fixed-form rule for the shared remote, dcn-2610150000000001; iss-2610161015370582).
• dcn-26101614122834502026-10-16 — A hand-back stands while origin's default branch holds the record at the blob its tombstone names (facilitator-on-delegation, drain-many-accounts): the claim package reads that blob from origin's default branch as last fetched, as an entity tag names the version a conditional request was made against; only a blob read there that differs lifts the hand-back, never an unreadable branch or a record held in no file or in several; a blob read from a branch the act's fetch could not refresh can only read as changed sooner than a fresh one; and a release asked to hand back a record the branch does not hold in exactly one file pushes a plain tombstone and says why rather than refusing, so the reservation never outlives the hand-back (grounds: entity tags and If-Match in RFC 9110 sections 8.8.3 and 13.1.1, and git's content-addressed object model; spc-2610161044461448 step 3; iss-2610161015370582).
• dcn-26101618264435242026-10-16 — A yes whose hand-back a move cannot publish keeps it pending in the drain's state and publishes it over the issue's next release on origin (facilitator-on-delegation, drain-many-accounts review round): when the hold the yes would release has moved on (this person renewed or reserved the issue again by hand, another took it over, a person released it), when the drain took none because this person held the issue live from this copy, or when the release did not reach origin, the route says the hand-back is not yet published and why, the drain keeps it (pending_hand_backs: issue, kind, the blob the yes was judged over, why, when) and carries it into the next drain, and each later move whose view shows the issue's tip as a tombstone marking no hand-back publishes it as that tombstone's child, fenced on the tombstone and on the judged blob; a tip already marking a hand-back, a record finished or changed on origin's default branch, or one origin holds in no one file ends it with nothing published. The drain never releases a person's own reservation to publish it, so it waits for the person's release rather than taking the issue (grounds: dcn-2610161040365515, dcn-2610161806433529, dcn-2610161315385888; spc-2610161044461448 steps 2 and 3; the review of steps 1 to 18).
• dcn-26101619311226062026-10-16 — Refines dcn-2610161412283450 and dcn-2610161806433529 on a reservation made over a standing hand-back (facilitator-on-delegation, drain-many-accounts review round 2): a drain's reservation that would take over, or renew, the reservation at the issue's tip reads that reservation's first-parent line down to the tombstone it was made over, the same walk a plain release keeps a hand-back by, and backs off when that tombstone marks a hand-back whose record origin's default branch holds unchanged, whether the reservation over it is lapsed or still live, from this copy or another; a walk that cannot be read backs off too, since it cannot show the hand-back no longer stands. A person's own take-over or renewal goes ahead, as a person's own reservation over the hand-back's tombstone does. Reading the tip alone let a drain build an issue that waits on a person once that person's reservation over it lapsed (grounds: dcn-2610161412283450, dcn-2610161806433529; spc-2610161044461448 step 3; the re-review of the fix round).
