Enforcement-plane custody for the repo split

Context

Graduated from Discussion #17780 at §6.2 quorum (Claude [AUTHOR_SIGNAL] + non-author GPT [GRADUATION_APPROVED] @ 18153737). Runway anchor: D#17782 Wave 2. Gates neomjs/neo#17500's cutover feasibility.

Scope cut 2026-08-26 — operator KISS ruling, zero tolerance for added machinery. Four clauses removed as machinery for problems we do not have at N=3 enforcement targets; two were also built on a dead premise. Details in Cut Scope below. The cut is a reduction against an operator ruling, not a quorum bypass and not a weakened bar: every surviving AC keeps its original strength. @neo-gpt-emmy (signatory) and @neo-gpt (OQ8 author) are notified.

The Problem

Enforcement custody in neo is distributed by author-location, not subject. The split makes that fail three measured ways on cut day:

  1. Leaving teeth (fails loud): .husky/pre-push:16 — guard 2 of 3 under set -e — invokes ai/scripts/lint/check-commit-authorship.mjs, a Brain executable that leaves. Every Engine push then dies mid-chain, reading as "my push is broken".
  2. Inverse straddles (police ghosts): stay-side teeth guarding leaving subjects (aiconfig-antipattern-lint, aiconfig-test-mutation-lint, atomic-write-shape-lint) go silently green forever once the subject departs.
  3. Trigger starvation (silently never runs): pull_request path filters watching ai/** never match post-move. The workflow stops running, and the absence of a run is not a red.

Coupling measured across three snapshots: 19 files/69 ai/scripts refs at neomjs/neo#17500's filing → 20/75 → 20/73 (467fd122f3). 21 of 44 workflows carry Brain-coupled teeth — re-measured at origin/dev on 2026-08-26; the body said 20 and the coupling grew by one while this ticket sat, which is the same direction the three snapshots above already trace. Read-back coordinate and the AC-1 baseline are at comment 5426844579.

The binding reality that sizes this ticket: live dev requires exactly one status context — integration-parity — out of 44 workflows. A green workflow that is not a required context gates nothing. That single fact is why the binding half of this work is one read-back, not a subsystem.

The Fix

  1. The authorship guard leaves with the Brain — it is not relocated. Measured, not assumed: check-commit-authorship.mjs imports ai/graph/agentCoAuthorEmails.mjs, which imports ai/graph/identityRoots.mjs509 lines with 37 ai/ importers including configBase.mjs, the memory-core MCP server, and the daemons. That is Brain core. Moving the script to buildScripts/util/ would not sever the crossing, only lengthen it — PR neomjs/neo#17273 established exactly this and moved the file into ai/ for that reason. The Engine therefore drops the invocation; the guard travels with ai/ in neomjs/neo-agent-brain#13's receive set.
  2. Teeth move with their subject. Brain-coupled workflows land in neo-agent-brain with or before the code they police. Each repo carries its own workflow files — no reusable-workflow indirection layer for two repos.
  3. Fission only where a file genuinely straddles. test.yml splits along its existing run_integration / run_parity seam (integration→Brain, parity/e2e→Engine). engine-brain-boundary-lint becomes two one-sided guards. Any other straddler gets ONE named owner in the PR — never a cross-plane watcher.
  4. Binding: verify, don't police. Confirm integration-parity still exists and is still required after the split, read back once and recorded in the PR.

Acceptance Criteria

  • AC-1 — the Engine stops invoking what leaves: .husky/pre-push drops the check-commit-authorship.mjs line and commit-authorship-lint.yml leaves with the guard; afterwards .husky/* and .github/workflows/** reference nothing under ai/ (mechanical grep witness in the PR). Removal merges only after neomjs/neo-agent-brain#13 lands the guard in the Brain (receive-before-remove). Named consequence, not papered over: Engine-side agent-commit authorship is then unenforced in the Engine. Closing it needs either a duplicated roster (SSOT violation) or a distribution mechanism (new machinery) — both refused today; the gap is recorded here for a post-split decision and nothing is built for it now. (Original AC-1 said "relocate to buildScripts/util/". Falsified 2026-08-26 against the tree — see Fix §1.)
  • AC-2 — Brain tranche moves with its subject: the 20 Brain-coupled workflows, test.yml's integration half, and the Brain-side boundary guard land in neo-agent-brain with or before the code they police, with merge-order evidence; verified before the neo-side removal merges.
  • AC-3 — test.yml fission: integration→Brain, parity/e2e→Engine along the existing classifier seam; both halves green in their plane.
  • AC-4 — the required context survives: after the split, integration-parity (or its named successor) exists and is still a required context on the branch that needs it; read-back output pasted in the PR. No receipt files, no drift detector.
  • AC-5 — trigger reach proven once: every moved or path-filtered workflow links an actual post-move run. Absence of a run is the failure mode; a link is the proof.
  • AC-6 — fork-safety witness: fork clone + npm install, zero org access, hooks and CI run clean (D#17782 goal 5).
  • AC-7 — ADR 0040 §2.7: records the custody decision — custody follows the subject — in the same PR. Enforcement custody only; the skill-custody claim was withdrawn by its author as overreach and belongs to the cut.

Cut Scope (2026-08-26)

cut was why
The org registry with enrollment/onboarding/retirement semantics AC-8 A lifecycle subsystem for three enforcement targets. Canonical deleted its own enrollment.json in the same de-bloat pass. Revisit when N justifies it; @neo-gpt's OQ8 field-ownership ruling survives as the design note for that day.
Binding read-back receipts + out-of-band mutation drift detection AC-6 A committed policeman for a mutable surface guarding one required context — the same machinery class this week's SSOT incident just killed. AC-4's one-time read-back covers the split.
Binding column across all 44 census rows AC-1 Six fields × 44 rows of documentation against a live reality of one required context.
neomjs/.github reusable workflows + aggregated per-repo caller (ED1+ED2) Fix §1 Doubly dead: it rode D#17756's committed-bundle distribution, which the operator overturned in favour of an npm dependency (workflows do not travel by npm anyway), and an indirection layer costs more than a workflow file in each of two repos.
AC-10 org Actions-policy read AC-10 Completed 2026-08-25: policy gates nothing for our bots. Result recorded here; the AC has nothing left to do.

Out of Scope

Skill distribution (D#17756 / neomjs/neo#17798 — npm dependency, never copied bytes) · the extraction wave itself (#17500) · seat binding (D#17644) · plan-tier changes · the deployed-plane severe test (D#17782 Waves 0/4) · rewriting any guard's logic — custody moves, behavior does not.

Discussion Criteria Mapping

D#17780 pre-ticket gates 1–5 satisfied at graduation (anchors in the Discussion body rev-4). Its carried ACs mapped one-to-one into this ticket's original AC-1…AC-10; four are now cut per the operator ruling above, with the rationale recorded row-by-row rather than silently dropped.

Unresolved Dissent

None on the graduated shape. The 2026-08-26 scope cut is operator-authorized and open to challenge by either signatory.

Unresolved Liveness

@neo-gemini-pro: operator_benched per §6.5; revalidation on reactivation is not Tier-2-required for this artifact.
