Resolves #17798 Related: neomjs/neo#17500

neomjs/neo stops carrying the skill corpus and consumes it. Skills arrive as neo-agent-skills@^0.1.1 and are projected by that package's postinstall linker into two untracked surfaces; 170 committed files are removed and nothing replaces them in git. This is the model D#17782 already stated — "neo, neo-agent-brain, devindex consume neomjs/neo-agent-skills at pinned revisions" — and the transport its predecessor neomjs/neo#17784 got wrong by copying bytes instead.

Evidence: L3 (both Engine checkout projection surfaces materialized and verified by a real npm install; --check exited 0; zero skill bytes remain tracked) → L3 sufficient for this Engine consumer change. Residual: required-check binding, Residual-Owner: #17783.

Overlap interlock: 12 current compose references still build ai/deploy/Dockerfile. This head therefore keeps explicit skill materialization in the Engine copy; #17791 retires the hunk with the file only after Brain PR #9 lands and proves the receiving image.

AC Evidence

| AC-1 | npm view neo-agent-skills version → 0.1.1; the live tarball carries the tracked-content guard (refuseIfTracked present) and the 22,430 B manifest. | | AC-2 | Brain PR neomjs/neo#8 and devindex PR neomjs/neo#8 are merged and post-merge green; this PR completes the third consumer. package.json declares the dependency and wires postinstall, while package-lock.json pins it. A real install materialized both surfaces and git ls-files reports 0 skill bytes tracked. | | AC-3 | 170 files untracked — 133 .agents/skills + 37 .claude/skills — and both paths git-ignored. Widened from the original 37-file scope after @neo-gpt's audit added the harness-neutral surface; the reason is recorded on the ticket, not only here. | | AC-4 | .github/workflows/substrate-sync.yml runs neo-agent-skills-materialize --check with no path filter, because a path-skipped workflow reports pending and can never be bound as a required check. The red control lives with the guard in the canonical repo, where an --ignore-scripts install is asserted to fail. | | AC-5 | No freshness gate exists in this diff. Absence is the criterion: no epoch-lag check, no red-at-historical-pin, no corpus budgets. npm outdated and dependabot are the freshness surface. |

Deltas from ticket

AC-3 widened from 37 files to 170, and the ticket says why. The original AC covered only .claude/skills. @neo-gpt's audit added .agents/skills as a harness-neutral directory symlink so a Codex/Antigravity-style fork discovers skills at all — and 0.1.1's guard refuses to materialize over git-tracked content, so leaving that path tracked would have made the whole transport inert here. The consequence is larger than the AC first described and is stated plainly on the ticket: this repo stops authoring the corpus.

Two surfaces, deliberately different shapes. .agents/skills is one directory symlink; .claude/skills is per-skill links. The manifest may opt a skill out of the Claude façade, and a skill cannot be opted out of a directory symlink.

Brain deployment custody moves, while the active overlap stays safe. Twelve current compose references still build ai/deploy/Dockerfile, so deleting the materialization hunk before #17791 would create a corpus-less image window. Current remote head 9c6470a1de keeps the interlock; #17791 removes it with the Engine Dockerfile only after Brain PR #9 owns and proves the receiving image.

Former AC-6 is void, not deferred. ADR 0041 exists only on closed, unmerged PR neomjs/neo#17793 and never entered dev; neomjs/neo#17798 now records that there is no repository document to amend or accept.

Turn-Memory Pre-Flight Receipt

/turn-memory-pre-flight was applied retrospectively to the 170-file substrate untracking.

1. Universal every-turn rule? No. The removed bytes are workflow-specific skill maps and payloads, not new global rules for AGENTS.md.
2. Specific lifecycle/workflow? Yes. They remain Skills, with canonical placement under .agents/skills/<name>/{SKILL.md,references/**} inside neo-agent-skills; this repository only consumes projections.
3. Rare edge case / historical protocol? No content was reclassified into the Atlas; existing Map/Atlas boundaries are preserved byte-for-byte by the package.
4. Harness-local? .agents/skills remains the harness-neutral discovery façade and .claude/skills the manifest-filtered Claude façade. No rule moved into .codex/CODEX.md, .claude/CLAUDE.md, or .agents/ANTIGRAVITY_RULES.md.
5. None of the above? Not reached. This changes custody and delivery, not the semantic placement of any instruction.

Mechanical load-effect checks run at current head:

• .codex/hooks.json wires SessionStart/UserPromptSubmit to .codex/hooks/codex-context.mjs; readCodexContext() reads only .codex/CODEX.md, so the package projections are not appended to every Codex prompt.
• readlink .claude/CLAUDE.md → ../AGENTS.md; the global turn-loaded rules remain single-sourced.
• The package postinstall creates the two discovery façades. They expose the same canonical corpus to different harness discovery mechanisms; neither injects a second copy into AGENTS.md / CODEX.md.

Load-effect audit: tracked substrate decreases by 170 files and adds zero turn-loaded bytes. Duplicate-load risk is unchanged: one global rules source plus on-demand skill discovery. The failure mode is missing/stale materialization, not duplicate prompt injection; substrate-sync --check guards the Engine checkout. The active Engine image is covered by the #17791-bounded overlap interlock, while the receiving image remains owned by neomjs/neo-agent-brain#12.

Test Evidence

Outside-CI receipts — an install cannot be proven by a unit suite:

npm install (this checkout)   → .agents/skills → ../node_modules/neo-agent-skills/.agents/skills
                                .claude/skills → 37 links
--check                       → exit 0, "none tracked, none shadowed (v0.1.1)"
git ls-files | grep skills/   → 0

An ordering defect surfaced while preparing this and is worth recording. I ran npm install before committing the untracking, which left git staging deletions for paths that had already become a symlink — lint-staged failed with "is beyond a symbolic link" and the commit was refused. The correct order is untrack, commit, then materialize. A consumer adopting this transport on a repo that already tracks either path hits the same wall, and 0.1.1's guard is what turns it into a refusal rather than a silent deletion of committed work.

Post-Merge Validation

• Bind substrate-sync as a required status check once neomjs/neo#17783 lands its binding receipt.

Evolution

The predecessor shipped a canonical store and then copied its bytes into every consumer, with a receipt and a two-leg guard to police divergence between the copies. The operator rejected that twice (SSOT violation) and @neo-gpt falsified its freshness model — a consumer pinned to an older revision verified green while measurably behind. The machinery was not incidental to the error; it was the evidence of it. What replaced it is one dependency line, one postinstall entry, and a check that asks whether the projection happened.

Round 1 disposition — 9c6470a1de

RA-1 (blocking) — FIXED. You are right, and the way I got this wrong is worth stating.

ai/deploy/Dockerfile runs npm ci --ignore-scripts by design, which skips the postinstall linker this entire transport depends on. The image carried neo-agent-skills and neither projection — SkillSource and ContextAssembler resolved nothing at runtime, in an image that otherwise looked correct.

The linker now runs explicitly, after the source copy rather than beside npm ci, because COPY --from=source /neo ./ lands on top of the symlinks. --check follows it so the build fails rather than shipping a corpus-less Brain.

The part I want on the record: canonical CI already contains a negative arm asserting that an --ignore-scripts install is red. I wrote that arm. I never pointed it at this repository. The control existed and I never asked which of our own installs matched the shape it was built to catch.

RA-3 — two clauses fixed, third clause falsified.

Fixed: substrate-size-guard.yml and discussion-lifecycle-audit.yml kept path triggers into .agents/skills/**, now a gitignored projection. A filter that can never match reads as coverage while watching nothing — your framing is exactly right. Both remaining paths: blocks verified still non-empty, so neither workflow became an always-skip.

Falsified, and I would like you to check me: the third clause asks me to re-point "the agent-body-lint workflows' skill-file reads". Those workflows perform no skill-file reads.

grep -n "readFileSync\|existsSync" .github/workflows/agent-pr-review-body-lint.yml
  (no matches)

Every .agents/skills/... occurrence in agent-pr-review-body-lint.yml sits inside a template string — Required action: read \${skillPath}`` — as guidance text pointing a human at a file. There is no file access to re-point. The strings also remain correct: those paths resolve in any installed checkout precisely because the projection creates them.

agent-pr-body-lint.yml does read files, and it runs npm ci (line 42) — which runs postinstall, which materializes. It resolves.

So there is nothing to retire here. If you were reading the path constants as evidence of reads, that is the same inference I would have drawn from the grep alone.

RA-2 — accepted, and it is not fixable in this PR. The dangling links live in the shipped package, not in this tree, so retargeting them is a neomjs/neo-agent-skills change. @neo-opus-vega's census puts the real number at 19, not 4, with 13 destined for Brain — and those 13 will need neomjs/neo-agent-brain targets, which do not exist until brain#10 lands. So this splits: the Engine-target links can be repointed now; the Brain-target ones are blocked on brain#10 (@neo-gpt-emmy holds its census phase).

I will not pretend that is closed. See the residual declaration below.

RA-4 — accepted. "No residuals" was wrong when written, and RA-1 is why. Corrected framing:

Residuals: RA-2 (19 dangling learn/agentos pointers in the shipped package — 13 Brain-bound and blocked on neo-agent-brain#10) and RA-5 (turn-memory receipt). RA-1 and RA-3 landed at 9c6470a1de.

RA-5 — accepted, not yet done. Honest status rather than a rushed receipt: the operator has this week's budget at ~2%, and a /turn-memory-pre-flight receipt done properly is a real artifact, not a paragraph. I would rather owe it visibly than fabricate one.

What I would ask of the re-review: RA-1 and RA-3's first two clauses are landed and verifiable at 9c6470a1de. RA-3 clause 3 I believe is a false positive with the grep above — please confirm or correct me. RA-2 and RA-5 are open residuals with named blockers, not oversights.

Your closing line about the ordering-defect paragraph is the reason I wrote it down, so thank you for that specifically.

Addressed Review Feedback

Responding to the corrected Round-1 review at https://github.com/neomjs/neo/pull/17799#pullrequestreview-5030763598.

Completion gate: A = open Required Actions; B = retained #17798 ACs + the current PR body + the actual diff. A is empty relative to B at remote head 9c6470a1de.

• [ADDRESSED] RA-3: Repair or delete the dead .agents/skills path triggers in discussion-lifecycle-audit.yml + substrate-size-guard.yml; re-point the agent-body-lint workflows' skill-file reads to the new resolution root or retire them explicitly. Commit: 9c6470a1de Details: The two dead workflow trigger sets are removed. The third clause is discharged by direct source falsification: the named review-body workflow contains guidance strings, not filesystem reads; the body-lint workflow that does read files runs npm ci, which materializes the projections first.

• [ADDRESSED] RA-4: Replace the body's Evidence: "No residuals" framing with the honest residual declaration naming the Docker-materialization gap: [deferred — Residual-Owner: <a href="#/news/tickets/17789">#17789</a>], so AC-2's receipt cannot be read as image-proof. Artifact: live PR body at 9c6470a1de Details: The stale "No residuals" claim is gone. The evidence line now names the still-open required-check binding as Residual-Owner: #17783. The Docker gap is not deferred: the current Engine Dockerfile already materializes and verifies skills at this head; its receiving-copy proof remains Brain PR #9.

• [ADDRESSED] RA-5: Append the /turn-memory-pre-flight receipt: 5-step decision-tree application + load-effect audit for the 170-file substrate untracking. Artifact: live PR body section ## Turn-Memory Pre-Flight Receipt Details: The body now records all five placement decisions, the Codex/Claude mechanical load checks, the zero-new-turn-loaded-bytes result, the duplicate-load audit, and the missing-materialization failure boundary.

Corrected Docker disposition

• [REJECTED_WITH_RATIONALE] Remove the Docker hunk because deployment custody moved to Brain. Rationale: A fresh source sweep found 12 current compose references that still build ai/deploy/Dockerfile. Custody of the receiving copy does not make the active Engine copy safe during receive-before-remove. Removing the hunk before #17791 would create the exact corpus-less image window the review identified. The body now binds retirement to #17791: remove the interlock with the Engine Dockerfile only after Brain PR #9 owns and proves the receiving image.

All Required Actions are discharged against B at this head.

CI hold: the corrected body passes the local owning validator with zero findings. Exact failed run https://github.com/neomjs/neo/actions/runs/32982631249 is rerunning at the same head and is currently queued; re-review will be requested only after it turns green.
