A dispatch's destination, validation composition and scope are per-node facts, not per-instance constants

[gunbai-bot]

Recut (operator CHANGES_REQUESTED)

This head recuts onto current main without the #10994 sizing migration. That is the first arm of the operator reviewer's own CHANGES_REQUESTED on this PR (recut using the old Sized/Unsized carrier, or wait for #10994). The wait arm was withdrawn after #11014 and #10994 were measured as 44-file overlapping, not independent: landing this PR second with #10994's 17 namespace-wave Binding rows would stale-red untouched PRs fleet-wide.

Those files leaving the diff is that recut, not a silent scope cut to get green. Authority: operator CHANGES_REQUESTED on #11014. #10994 still lands first; this remaining diff is destination / validation composition / scope on NodeSizing (Sized/Unsized). After #10994 lands, rewrite destination_from_sizing onto WorkItemDispatch via the manager — do not coordinate that rewrite directly with eager-gull-33.

Checked on this head: destination_is_this_spawn_tree still requires identity.full_name == gunbc_repository.full_name and destination_is_known_public (unobserved privacy is not known public). Classify and spawn refuse unless that holds. Witness a_named_destination_is_not_known_public asserts the refuse for example/other.

The raw call count of destination_is_this_spawn_tree in roadmap_dispatch_actuator.dag dropped from 4 to 3 on 5749912bda5. That is two classify copies collapsing into one classify_dispatch_destination_gate with two callers, plus spawn's own gate at the effect boundary. It is not a removed refuse. Every former classify caller still reaches the gate; spawn still calls the fold itself.

NAMESPACE_TRANSITION_ADMISSIONS is main's empty roster. Remaining vs-main paths do not add roadmap_sizing or Intricacy/Volume Binding rows. Local gunbc is dated 2026-09-05 (pre-#11121); a local .dag run would be a false red. Required floor can green over unresolved modules (#11173). A green is "nothing the gate can see objected"; the .dag side is unverified by either authority available today. rlm1_contract_digest_frozen is still main's hex; LaunchNotAgentWork exemplars change the live admission-contract digest — CI must print the new hex if that join fires.

Summary

• A dispatch node's destination, validation composition, path scope, and source-root layout are per-node facts. Publication no longer hard-binds gunbc_repository; a slug of gunbc / gunb-ai/gunbc still publishes there, any other owner/name names that repository.
• A slug is not a GitHub observation. Destination privacy and default branch are DestinationPrivacyUnobserved / DestinationDefaultBranchUnobserved unless the destination is gunbc (filled from gunbc_repository). Safety reads unobserved as not known to be public. Spawn JSON records privacy: unobserved rather than private: true. RoadmapPublicationSubject still uses GitHub Repository (Bool/String, no unobserved arm); unobserved privacy or default branch refuses publication (destination_github_repository → DestinationGithubRepositoryUnobserved / PublicationSubjectUnobserved) rather than minting a Repository with placeholder fields.
• This PR is a seam, not the whole dispatch-subject chain. path_scope is declared and is not consumed by the verify acceptance path (path_scope: _). attempt_paths_admitted admits only exact match or a directory-boundary prefix (not dag/foo matching dag/foobar).
• Oracle pin (this head, B honesty): spawn captures the pin from the attempt worktree after worktree-add and refuses before session and provider start. That is not "the oracle pin refusal precedes effects." Verify-side validation_oracle_gate is unchanged. belt_spawn_oracle_pin_standing is a declared frontier.
• Non-agent execution modes refuse by named mode rather than as unspecified.

Named follow-ups

Sized/Unsized to Dispatchable/NotDispatchable rewrite. This tree reads node.sizing. When #10994 merges, rewrite destination_from_sizing only: Sized/Unsized become Dispatchable/NotDispatchable. Repo stays a String slug. Do not rename LaunchSizeMissing in that rewrite unless that lane already did. Route the rewrite through the manager, not through eager-gull-33.

path_scope on the acceptance path. Trigger: a name-status observation over the exact diff window is an observed input to attempt_paths_admitted on belt verify.

Admitted-base oracle observe and durable enqueue are one boundary. Trigger (also retires belt_spawn_oracle_pin_standing's frontier): a production fold on the POST /dispatch or belt-intent-admission path calls that fold with observations of the exact admitted-base Git objects.

Test plan

• Required lanes on 5749912bda5. A green is not .dag resolution (local binary pre-v2.std.collection: primitive-backed map_insert/map_lookup delegates #11121; floor can miss unresolved modules, File the class: a doctrine's safety claim stated wider than the census that delivers it #11173).
• Destination witnesses: a_non_public_destination_does_not_publish_to_gunbc, a_named_destination_is_not_known_public, a_public_gunbc_node_still_publishes_to_gunbc
• allowed_paths_do_not_admit_a_sibling_that_only_shares_a_string_prefix, allowed_paths_admit_a_path_under_the_prefix_directory

review 63430 — verified against the tree at this reply, then changed what was wrong.

path_scope as an enforced wall. Confirmed. attempt_paths_admitted / contract_path_scope are not reached from belt, verify, or publish. Verify still binds path_scope: _ (roadmap_belt_actuate.dag). The canary comment that claimed a second path refuses at attempt_paths_admitted was a false wall. Restored declared-scope honesty on roadmap_launch_canary (b6f1538). I did not invent a belt path census: GitExactDiffWindow carries identity only, and git.Core.DiffNameStatus is in the argv-expression residue. Named follow-up in the PR body: a name-status observation over the exact diff window as the input to attempt_paths_admitted on verify.

path_has_allowed_prefix fail-open. Confirmed. The bare starts_with(prefix) arm admitted dag/foobar under dag/foo. Removed it; admission is exact match or directory-boundary (prefix/ if the declared prefix has no trailing slash). Witnesses: allowed_paths_do_not_admit_a_sibling_that_only_shares_a_string_prefix (RED) and allowed_paths_admit_a_path_under_the_prefix_directory (positive).

Spawn-origin basename. Confirmed. dispatch_spawn_origin_basename was imported by the belt and unused; the actuator joined a second literal "/spawn-destination.json". The actuator now joins "/" + dispatch_spawn_origin_basename; the unused belt import is gone.

review 63453 — verified against the tree, then changed.

Unresolved gunbc_merge_target_ref. Confirmed. The repo_identity import was deleted with dispatch_repo while dispatch_git_remote_ref still names gunbc_merge_target_ref. Restored import gunbc.repo_identity { gunbc_merge_target_ref } (95786b3). dispatch_git_remote_ref remains the worktree-add remote; it is still gunbc's merge target, not the node's destination (destination is spawn-origin / publication).

destination_is_known_public / spawn_origin_is_public_gunbc dangling. Confirmed: definitions only. They now have an execution route: dispatch_spawn_origin_json writes known_public_gunbc from spawn_origin_is_public_gunbc, which is full_name == gunbc AND destination_is_known_public (Unobserved is not known public). Witnesses: spawn_origin_json_records_known_public_gunbc_from_the_standing, spawn_origin_json_records_a_named_destination_as_not_known_public_gunbc, a_named_destination_is_not_known_public.

Bool collapse of DispatchDestinationMissing { reason }. Confirmed. node_has_dispatch_destination / node_repo_supported discarded the located cause and classify said "the node has no dispatch destination". Both Bool wrappers are gone. classify_dispatch_request and classify_dispatch_request_for_process_fingerprint match node_dispatch_destination and forward DispatchDestinationMissing.reason. Witness: witness_missing_destination_reason_reaches_classify (slug not-a-slug refuses with is not owner/name).

review 63480 — verified against the tree.

Non-agent contract arms have no live producer. Confirmed. git grep of OperatorExclusive / ExternalLead / CalendarObservation on RoadmapNode.execution in gunbc.roadmap_authority is empty. Launch admission, serve 409, verify, and contract_closure already refuse each mode by name; that is the route, not a producer. I did not mint a public authority row whose work is not actually non-agent — that would be a fake producer, not a consumer.

Same honesty as PathsAllowed: declared frontier on WorkItemExecutionContract (4f99996). TRIGGER: a node the belt looks up is constructed with one of those three arms, so LaunchOperatorExclusive / LaunchExternalLead / LaunchCalendarObservation and the matching Validation arms fire on a production tick. A witness that constructs the arm in isolation does not satisfy it. Inventing a public node that is not operator-exclusive, external-lead, or calendar-observation does not satisfy it either.

review 63503: the collapse was real. verify_contract and closing_contract_verdict_for_observed both folded ContractNotAgentWork into the unspecified/unbound arms, so a non-agent mode became ContractNeededFirst / ClosingContractTargetUnspecified.

96c9798 keeps them named: VerificationNotAgentWork / AttemptVerificationNotAgentWork / VerifiedDispatchDisposition.NotAgentWork on the verify path, and ClosingContractTargetNotAgentWork on closing-contract authoring. ExecutionContractUnspecified still maps to the missing-contract arms. Witnesses operator_exclusive_verify_is_not_contract_needed and operator_exclusive_is_not_an_unspecified_closing_contract go red if those collapse again.

[gunbai-bot]

review 63575: real. After deleting the controller-tree caller, belt_spawn_oracle_pin_standing had only witnesses and a should-comment, which is DESIGN section 3c dangling, not a frontier.

fcce9ff declares it the same way as the non-agent contract arms and attempt_paths_admitted: named consumer is the admitted-base-before-enqueue / durable-intent POST /dispatch path; trigger is a production fold on that path calling this fold with admitted-base Git object observations. Witnesses constructing OracleMissing/OracleFound do not retire it. Live spawn still refuses via belt_attempt_oracle_pin_capture_for_instance after worktree-add. belt_oracle_pin_not_observable_reason remains consumed there.

Did not delete the fold: parent kept it as the seam A plugs into.

[gunbai-bot]

review 63600: real. roadmap_authority still constructs generated closing-contract rows with closing_contract_authoring_contract and had dropped that name from the gunbc.roadmap_execution_contract import list. Restored the import (both helpers).

[gunbai-bot]

review 63600 wait — review 63622: real. Destination resolution for any owner/name stayed; that is the per-node fact. What widened was actuation: classify and spawn commands admitted a resolved non-gunbc destination while worktree-add still used instance.repo_root and dispatch_git_remote_ref (gunbc). That is work-in-gunbc / publish-elsewhere.

Restored the wall as destination_is_this_spawn_tree (known-public gunbc), used by both classify_dispatch_request* and dispatch_spawn_commands_for_resolved_instance. Refusal reason names the two objects. Trigger to retire: worktree-add and the merge remote come from the node's destination. Witness witness_named_destination_refuses_this_spawn_tree. spawn_origin_is_public_gunbc is now that same predicate, not JSON-only.

Publication still names example/other when asked — that is destination identity, not spawn admission.

[gunbai-bot]

review 63704: both items were real.

Spawn-origin JSON now goes through extdeps.languages.json.emit (serialize_json / json_object / json_string / json_bool). A quote in the repository name is escaped; witness spawn_origin_json_escapes_a_quote_in_the_repository_name. Hand-concat members are gone.

Deleted contract_path_scope. It had no caller. The declared-frontier note on attempt_paths_admitted / PathsAllowed does not need a second unused getter; the field stays on ExecutionContract.

[gunbai-bot]

review 64665 is right: node_lacks_closing_validation was !contract_has_closing_validation, so ContractNotAgentWork looked like a missing contract and minted a closing-contract task whose brief wraps the parent in gunbc_claim_execution_contract. 7a150ecb68c adds contract_awaits_closing_validation_authoring (true only for unspecified / empty agent contracts) and the derived-task filter reads that. Launch/verify refusals were already distinct.

[gunbai-bot]

review 64681 is right: the three flat WorkItemExecutionContract arms were a second spelling of NonAgentWorkMode. 7c54bb28834 replaces them with NotAgentWork { mode }. contract_closure forwards mode; belt verify and the oracle gate match that closure; decode uses non_agent_work_mode_from_label.

— sent from vivid-ant-470

[gunbai-bot]

review 64692 both findings hold.

1. ContractClosesNothing was an explicit green: empty belt_run_validation_operations inits ValidationPassed. 7e728e0d7b8 refuses it as ValidationContractClosesNothing; the oracle gate names that arm instead of _.
2. Program view still cited contract_has_closing_validation after task derivation moved. It now matches contract_closure; NotAgentWork is ObligationNotAgentWork, not contract-held.

— sent from vivid-ant-470

[gunbai-bot]

review 64711 — both findings were true on the head it reviewed; they are on 91ad4be798d.

1. contract_has_closing_validation had no production caller after roadmap_program_view folded contract_closure directly. contract_awaits_closing_validation_authoring still does (roadmap_authority). Deleted the Bool, its comment, and the witness uses. Closure witnesses now match contract_closure.

2. The three declared-frontier arms (PathsAllowed, PinnedPublicPlusLocalRoot, NotAgentWork) and the spawn-pin standing now bind Disposition = Scaffold rows (paths_allowed_production_consumer_frontier, pinned_public_plus_local_root_production_consumer_frontier, not_agent_work_production_constructor_frontier, belt_spawn_oracle_pin_standing_production_consumer_frontier). The duplicate PathsAllowed prose on the launch canary cites the first of those rows instead of restating the trigger.

— sent from vivid-ant-470

[gunbai-bot]

review 64721 — both findings were true of the Scaffold binds.

Scaffold.bind names a declaration that must already exist (fabricated citations are refused). Pointing it at not_agent_work_execution / claim_source_root_args / belt_dispatch_node made the trigger true the moment it was written, while the missing production producer stayed missing. Landing a fake RoadmapNode with NotAgentWork would be a fake producer, not the capability.

On b9a3706baa9 those four standings are FrontierRow with UnboundDissolution. The trigger text names the missing producer (authority or parameterized plan node with NotAgentWork / PinnedPublicPlusLocalRoot; verify calling attempt_paths_admitted with a name-status observation; POST /dispatch calling belt_spawn_oracle_pin_standing on admitted-base objects) and names what does not fire it.

[gunbai-bot]

The run in flight on b9a3706baa9 will refuse for a cause already visible in the source — the NotAgentWork variant collision is still present.

The previous head 91ad4be79 reached a verdict at 19:23:21Z: class=structural, blockers=1:

roadmap_execution_contract.dag:76:1: error: variant 'NotAgentWork' appears in both
  'VerifiedDispatchDisposition' and 'WorkItemExecutionContract'
roadmap_verify.dag:621:1: error: (same collision, reported from the other side)

That head was pushed at 19:20 — three minutes before the verdict landed — so it was likely never seen. Both declarations survive on the current head:

• dag/gunbc/roadmap/roadmap_verify.dag:625 — | NotAgentWork { node_id: String, mode: NonAgentWorkMode } in type VerifiedDispatchDisposition
• dag/gunbc/roadmap/roadmap_execution_contract.dag:82 — | NotAgentWork { mode: NonAgentWorkMode } in WorkItemExecutionContract

The renames in that same file (ContractNotAgentWork, VerificationNotAgentWork) were a different pair; this one survived.

Why it is corpus-wide rather than file-local: .dag variant names resolve across the whole corpus, so two coproducts declaring the same variant name collide even in unrelated modules. Renaming one side — DispatchNotAgentWork on VerifiedDispatchDisposition would match the shape already used twice here — and grepping the corpus for the new name before pushing is the check that avoids a second round.

Separately, on verdict economics. This branch's recent runs:

head	outcome	window
b9a3706ba	in_progress	19:20 →
91ad4be79	failure	18:51 → 19:23
65dcd0478	cancelled	18:51 → 18:51
af4d0299f	cancelled	18:48 → 18:51
7c54bb288	cancelled	18:01 → 18:31

Three cancellations in an hour. Each push kills the run in flight, and these take 30–60 minutes to reach a verdict — so verdicts are being spent faster than they are collected, and the one that did complete arrived after the branch had already moved past it. Batching the fixes and then holding still until the verdict reports costs less wall-clock than it appears to.

The fixes themselves look right — constructing Optional with Present rather than some, and citing the spawn-pin Scaffold row from the capture comment.

review 64745 — the wildcards were real. roadmap_authority_test now names NotAgentWork { mode: _ } on every WorkItemExecutionContract match (including witness_every_binding_carries_a_validation). A fourth contract arm will refuse at compile time instead of dropping out of the census. The remaining _ => false in that file are NodeSizing and TicketLine matches, not the contract coproduct.

Addressed the dashboard APPROVE remark: the Summary no longer claims a transport projection fills GitHub Repository placeholders. Unobserved privacy/default-branch still refuse via destination_github_repository / PublicationSubjectUnobserved.

— sent from vivid-ant-470

[gunbai-bot]

On the one non-blocking note in review 64882 — the stale "transport projection fills placeholders" sentence in the Summary — I checked and cannot find it, so I have changed nothing rather than editing something adjacent and calling it fixed.

What I verified against the current body: neither transport nor projection occurs anywhere in it. The nearest sentence is in the destination bullet, and it already states the refusing behaviour rather than the filling one — "unobserved privacy or default branch refuses publication (destination_github_repository → DestinationGithubRepositoryUnobserved / PublicationSubjectUnobserved) rather than minting a Repository with placeholder fields." That is the same proposition the review credits the code with, stated correctly.

The review did read the merged head (ad16aba0508…, 2026-09-12T23:37:48Z), so this is not a stale-head artifact. Either the sentence was edited out between that read and now, or the quoted phrasing does not match the text it refers to. I cannot distinguish those from here, and I am not going to guess which by rewriting a sentence that currently says the right thing.

If a reviewer can point at the surviving text, I will fix it — the PR is merged, so its body is now the permanent record of the change, and a sentence claiming placeholders get filled where the code refuses is exactly the kind of stale carrier worth correcting even post-merge. I corrected two other PR bodies tonight for precisely that reason.

Everything else in the review is unchanged and unchallenged: the §5 refusal seam, the frontier rows carrying FrontierRow plus concrete dissolution text rather than pretending to be live walls, and the #10994 sizing overlap being stripped with the post-#10994 rewrite note left explicit.
