2026-10-18 — The away mode grants no push rights: the person's own standing instruction stays the authority to commit, push, and open or merge a pull request, exactly as before the mode existed (facilitator-on-delegation on the release orchestrator's ruling, itd-2610180912189125 after plan review round 2; supersedes dcn-2610181003456444, round 2's choice (a), and with it the guard entries that made setting the mode the person's act alone). The OS sandbox of spc-2610161751056096 fences only the agents abcd's runner launches, never the person's own interactive sessions, so for the sessions that actually stalled on 2026-10-16 the guard entries would never become a boundary, and their two days would buy a trust claim the plan cannot make. The fallback dcn-2610181003456444 already named is taken now, not on the live capture's evidence. Where the stop check finds owed work that needs a push (an unpushed branch, a reservation whose work no pull request carries, a behind or failing pull request once its local fix is committed), its reason tells the session to push if its standing instruction allows, and otherwise to queue the push with abcd mode queue for the person's return; a queued step that names the item's branch or record id, on word boundaries, hands that item back to the person for the rest of the window (a branch only while it holds commits its upstream lacks, so only the push waits), and the stop check stops naming it. The away mode is never treated as permission. The person-only acts gain pushing, opening or merging a pull request without a standing instruction that allows it. Who sets the mode returns to dcn-2610180913399042: the person, or a session on their word in that session; since the mode grants nothing, a mode set on a relayed word only keeps sessions working and deciding instead of asking, and the person sees who set it, from which working copy, and the literal abcd mode back on their next prompt. Making the mode the person's act alone moves to itd-2610170638184486 as named remaining work: the guard entry refusing an agent's abcd mode autonomous, its other routes (sh -c and script files), the shell-write and file-tool refusals on the away store, the refused attempts recorded and shown, the capture's checks of the person's ! command and of a relayed !, and the guard reading go run ./cmd/abcd and built abcd-<goos>-<arch> binaries as abcd for every entry, the ledger flip included, a security-relevant widening that gets its own review there (grounds: the release orchestrator's ruling of 2026-10-18 and the reviewer's addendum, both recommending the fallback; spc-2610161751056096 and adr-2610161621415708, which fence launched agents only; iss-2610170619247185, whose standing instruction already allowed pushes and auto-merge; the fallback clause of dcn-2610181003456444)

• dcn-26101809133990422026-10-18 — The away mode is a record of the person's absence, set by a verb and ended only by its time or by their word (facilitator-on-delegation, itd-2610180912189125 planning): abcd mode autonomous [--until <time>] records who set it (the holder name reservations already resolve from caller-local facts), when, and when it ends, where --until takes a clock time (its next occurrence, local time) or a full timestamp and a time already past is refused; without --until it is open-ended until abcd mode back. It sits beside the waiting-on badge, whose three words stay a closed set, and is not a fourth word. A human prompt during the window does not end it, since a brief return overrode the instruction on 2026-10-16 and a prompt from a peer looks the same. An agent sets it on the person's word in its session, and one set covers every working copy, so no peer has to relay it. This restates the product thinker's 2026-10-17 ruling that they say they are away, until a set time or open-ended, and say when they are back (grounds: itd-2610170638184486 decisions; iss-2610170619247185; brief invariant 10; internal/core/mode)
• dcn-26101810034564442026-10-18 — Only the person sets the away mode, its push rights are narrow, and the guard's refusal is a mistake filter (facilitator-on-delegation, itd-2610180912189125 review round 2, choice (a); refines dcn-2610180913399042, replacing its clause that an agent sets the mode on the person's word): the prompt hook cannot tell the person's message from one another session relays, and its input names no origin, so a relayed word could let an agent grant itself, and every copy, push rights. So the guard refuses every route to setting the mode that it reads: `abcd mode autonomous` by the binary on PATH, the plugin root's binary or a built `abcd-<goos>-<arch>`; a `go run` of a package ending in `cmd/abcd`; any of them inside `sh -c` or in a script file a shell runs (adr-2610091150447054); a shell write into the away store under `~/.abcd.noindex/away/`; and an Edit or Write tool call on a path inside it. The person sets the mode with their own `!` command, which the host runs directly without going through Claude and so without the pre-tool hook, or at a terminal. A refused attempt is recorded in the store and shown to the person on the next prompt. What the mode grants is the session committing and pushing its own branches and opening their pull requests; never the default branch, a tag, a release cut, another person's pull request, a branch this copy only checked out to review, or a force push; merging follows the repository's own rule. This is chosen over the fallback, and is enough for now, because the grant only governs an agent that follows refusals: one that ignores them can push without any mode, so no shape of the mode adds a boundary inside the person's own session; the guard stops a refusal-following agent from granting itself on a relayed word; the rights are narrow, and every push is reversible and visible on the forge; and the record (who set it and from which copy) and the recorded refusals leave a trail the person reads on return. The guard stays a mistake filter (adr-42, and the decision of 2026-10-17 on the default branch that keeps the headless approver one, naming the OS fence as the boundary). That fence (spc-2610161751056096) is the boundary only for agents abcd's runner launches, whose writes to abcd's home it confines to their own worktree; it does not fence the person's own interactive session, where the stall happened, so there the narrow grant and the trail are the mitigation. The fallback (the mode grants no push rights, and the person's own standing instruction stays the authority to push) applies instead if the live capture shows that a message relayed from another session can run as a `!` command, or that an agent's tool call can reach the host's shell mode (grounds: plan review round 2, choice (a), and the coordinator's two addenda; the host's interactive-mode page, which says shell mode runs commands directly without going through Claude and outside the sandbox that applies to Claude's commands; the abcd-source-ledger-flip guard entry; adr-2610161621415708)
• dcn-26101810170563072026-10-18 — The overnight-stall slice is trimmed to what closes iss-2610170619247185 and nothing else (facilitator-on-delegation on the release orchestrator's ruling, itd-2610180912189125 after plan review round 2; refines dcn-2610180937181929): it keeps (i) a session with owed work cannot end its turn silently, through the Stop hook stop check with the ownership rules, the qualifying wake and the cap handling the reviews required; (ii) questions rerouted by the act, every other question decided with abcd decide and the person-only acts queued; and (iii) the away record set, ended, lapsing after at most seven days, re-injected at start, compaction and every prompt, under its lock. Moved to itd-2610170638184486 as named remaining work: the person-only guard step (dcn-2610181016510153), with the guard's reading of go run ./cmd/abcd and built binaries as abcd; the ten-minute reuse cache of the away forge listing and its stale-cache fallback, so each away check makes at most one listing under its ten-second deadline and a failed read judges from disk naming the pull requests as not read (adr-2610181003541997, still proposed, amended to match); abcd mode back printing more than one plain line per queued step and per recorded stop (any grouping, formatting or window summary); and the refused-attempt lines on the prompt. Kept despite the trim, because a review finding's fix rests on each: the created-branch list recorded in any mode (round-2 blocker 3, the drain's stacked branches, instance 2 of the issue); the Refs rule and word-boundary matching (blocker 4); the stale-ownership bounds (blocker 5); the wake deadline with the host's lateness and the cron cases (blocker 1); the forge's merge state for behind, with the one bounded listing and invariant 7's clause (blocker 2); the person-only acts list (blocker 6); the every-prompt line and the lapsed-window line naming abcd mode back (blocker 7); the block count and its possibly-forced label (round-2 (b)); the clearing rule's review and receipt terms (round-2 minors); the record's lock, ownership checks and seven-day cap (round-1 findings 6 and 7); the recorded ender (round-1 finding 13); the StopFailure record and the prose-question block (round-1 finding 11); and the badge verbs refused while away, which keeps a question from waiting on the person through the badge (dcn-2610180913431493). Re-estimated at 5.75 working days over seven steps, down from eight; about four is not reachable without reopening blockers 1 to 5, since the owed-work reading and the stop verdict with its cron parser carry 3.5 days between them and every rule in them answers a finding; the verdict is pure over the owed set, so two lanes could bring the elapsed time to about four days if the release orchestrator chooses (grounds: the release orchestrator's ruling of 2026-10-18 and the reviewer's addendum listing what stays; the spec's review rounds 1 and 2; AGENTS.md wired or it isn't done)
• dcn-26101810353557412026-10-18 — A queued push hands nothing back unless the person said pushes wait, and then only the unpushed item of a verified branch (facilitator-on-delegation, itd-2610180912189125 plan review round 3, finding F1; refines dcn-2610181016510153, whose grant of no push rights stands): by default a step queued with abcd mode queue hands nothing back, so the item stays owed and the stop stays blocked; the reason for an item that needs a push says to push if the standing instruction allows and to queue only if the person has said pushes wait, and a session with no instruction to push ends at the host's cap with the stop recorded for the person. A hand-back happens only when the away record carries the person's word that pushes wait, set with abcd mode autonomous --hold-pushes. The flag narrows what sessions do and grants nothing, so set on a relayed word it can at worst make sessions queue pushes they could have sent. Even then a queued step naming an own branch, on word boundaries, removes only that branch's unpushed item, and only while the disk shows the rest clear: its head contains its base's last-fetched tip, and a preflight receipt names the head where the repository mints receipts; where none are minted the clearing rule's equivalent, passing checks in the listing, can name only a pushed commit, so nothing is handed back there. It never removes a pull request that is behind or failing, a stacked branch the clearing rule still owes, a review outstanding, a reservation named by its record id alone, or a renewal, so a behind pull request whose merge is committed locally stays owed with pushes held and ends at the cap, recorded. The stop check records each hand-back in the away record under its lock, abcd mode back prints them, and the every-prompt line counts the queued steps and the handed-back items. TestQueuedPushHandsItemBack covers each case, the no-flag case handing nothing back (grounds: plan review round 3, finding F1, raised by both reviewers: the hand-back as written let a session exempt itself, replaying the first instance of iss-2610170619247185, where a behind pull request stayed behind all night; and it crossed the coordination intent's decisions that a stacked branch is cleared only by its merge and receipt and that a reservation's renewal must not lapse)
• dcn-26102410162081642026-10-24 — dcn-2610181016510153 is reversed in whole by adr-2610240850193281: the away mode no longer grants nothing, and a session no longer sets it on the person's word. A person-set autonomy grant now permits pushing a session's own branches, opening their pull requests and answering its own questions as a named role, set only by the person's explicit command; dcn-2610181003456444's person-only guard is reinstated with that wider grant (itd-2610240850336695). The reversal's grounds: a grant only removes a stop and needs no fence, which the reversed decision's boundary argument did not separate.
• iss-2610170619247185An agent session told to work autonomously overnight sat idle for about ten of the eleven and a half hours between 20:48 BST on 2026-10-16 and 07:13 BST on 2026-10-17, while it held owed work it could have done alone.
