AgentOrchestrator resolved two durable config defaults against process.cwd(). One of them lands inside the plane data root, so the same process wrote its Golden Path outcome history into a different plane depending on where it was launched — and nothing failed when it did.

Net: 1 file, +25/−5. No lint added — the census says there is nothing to mechanize.

Evidence: L2 achieved (both resolutions measured from two different working directories, showing the divergence and its removal; 18/18 AgentOrchestrator specs green at this head; lint-config-template-ssot green) → L2 required (runtime path resolution, fully reachable in CI). Residual: none — the C1 half of #15843 is explicitly deferred below, not silently dropped.

The divergence, measured

$ # outcomePath, resolved from the repo root
/Users/…/neo/.neo-ai-data/agent-orchestrator/golden-path-outcomes.jsonl

$ # the SAME default, resolved with cwd = /tmp
/private/tmp/.neo-ai-data/agent-orchestrator/golden-path-outcomes.jsonl

Two data planes, one process, silent. This is the alternate-realities class the plane contract exists to remove: .neo-ai-data is the plane root, so outcomePath is a plane member — and a member that derives its own root is exactly what the single-anchor rule forbids.

Worse, it was invisible to the runtime guard as well. assertPlaneMemberCoherence walks declared members against the resolved root; an ad-hoc path.resolve(process.cwd(), '.neo-ai-data/…') never declares itself, so the boot assertion could not see it either. The static gate did not scan ai/ for this class and the runtime gate only checks declared members — the defect fell between them.

The fix, and why the two paths differ

default was now why
outcomePath process.cwd() + .neo-ai-data/… the module-scope plane anchor it is plane data — one anchor, no member re-derives its own root
handoffPath process.cwd() + resources/content/… neoRootDir it is checkout content, not plane data — the repo root is the correct anchor, and the plane anchor would be wrong here

A config default is evaluated before any Provider exists, so it cannot read the resolved leaf — the env-free twin resolution over the discovered repo root is the sanctioned shape for exactly that chicken-and-egg case.

The seam is unchanged. These are Neo class configs: callers still relocate either path with Neo.create(AgentOrchestrator, {outcomePath}), and NEO_PLANE_DATA_ROOT still moves the plane. The spec already exercises that seam — it injects handoffPath on every case, which is what proves the default change is safe rather than merely untested.

What this deliberately does NOT do

It does not add a lint, and that is the finding. #15843 prescribed extending the config-mutation scan to ai/**. Three measurements retired that prescription:

  1. ai/** is already scanned. lint-config-template-ssot.mjs has SCAN_ROOT_REL = 'ai' and already runs two A1-adjacent detectors. Extending the B4 scanner there would be a second scanner over the same tree with overlapping rules.
  2. The decidable A1 class is empty. An env read is A1 when a leaf already binds that var. Cross-referenced: 24 direct env reads in ai/, 198 leaf-owned env vars, intersection of 1 — and that one is in a standalone mock server with no config in scope.
  3. The undecidable form is a noise generator. A regex-shaped process.env.X || detector flags ~31 of 32 sites, nearly all legitimate host-boundary facts (NEO_AGENT_IDENTITY, USER, PATH, ComSpec, TMUX_SESSION, XDG_DATA_HOME). PR #15880's body predicted this in writing — "an extended scan produces noise and gets muted, which is worse than the current honest silence" — and I walked at it anyway until the census stopped me.

The process.cwd() census told the same story: 36 sites, of which the overwhelming majority are correctcwd = process.cwd() as an injectable default parameter is the codebase's own idiom, standalone CLI tools legitimately take cwd, and a config establishing its own anchor has nothing above it to defer to. Two were genuine. Both are in this diff.

Deltas from ticket

Two, both narrowings, both recorded on #15843 before this PR opened.

  1. The title's second clause was already delivered by #15885 / PR #15880 (merged 05b76cab96). Retitled the ticket to its surviving scope during intake.
  2. The lint is dropped and the C1 half is deferred. C1's "Sanctioned form" cell in ADR-0019 §3 is being rewritten by my own open PR #15896; mechanizing C1 now would bake the pre-amendment rule into a fail-build gate, which is far more expensive to correct than a doc row. Resolves #15843 therefore reflects the A1 scope this PR delivers — see the ticket for the full classification.

Test Evidence

$ npx playwright test test/playwright/unit/ai/AgentOrchestrator.spec.mjs
18 passed

$ node ai/scripts/lint/lint-config-template-ssot.mjs
[lint-config-template-ssot] OK

The ❌ AgentOrchestrator failed: Error: boot failed line in that run is a deliberate failure fixture, not a regression — the suite exercises dead-letter and health-down paths on purpose.

Post-Merge Validation

  • A future plane relocation (NEO_PLANE_DATA_ROOT set) should move the outcome file with the plane rather than stranding it — previously it would have stayed wherever the launcher's cwd pointed.
  • The residual class is worth watching but not worth a gate yet: an ad-hoc path composed into .neo-ai-data is invisible to both the static lint and the member-coherence assertion. Two instances is not a population; if a third appears, a narrow "cwd composed into the plane root" guard becomes the right artifact.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The central mechanism is reproduced, not trusted — I ran the divergence probe against the exact head from a foreign cwd. The lint-drop decision is defended by measurements I could spot-check (one precisely, one within methodology variance). The C1 deferral is sequenced behind the author's own live ADR lane, which is correct dependency hygiene, not scope-shaving.

Peer-Review Opening: The most valuable line in this PR is "the census says there is nothing to mechanize" — walking at the prescribed lint until the measurement retired it is exactly how this family should run. One prose-precision item in the PMV, non-blocking.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Ticket #15843 (full body + all three author comments, including the retitle and the post-#15876 unblock); ADR-0019 §10.5 (the module-scope anchor doctrine, in context from today's two other reviews); the diff; ai/scripts/lint/lint-config-template-ssot.mjs:59-60 (SCAN_ROOT_REL = 'ai'); ai/planeConfig.mjs:106-121 (resolvePlaneDataRoot env semantics); my own env-read grep census of ai/.
  • Expected Solution Shape: Plane data derives from the one plane anchor (env-free twin resolution — the §10.5 (a) case); checkout content derives from the discovered repo root; the relocation seams (create-time config, per-member env) stay untouched; and a lint extension ships only if a census shows a population to mechanize.
  • Patch Verdict: Matches, and the load-bearing claim is independently reproduced: on the exact head 7fd7ada1ac, from cwd=/tmp, outcomePath resolves to <checkout>/.neo-ai-data/agent-orchestrator/golden-path-outcomes.jsonl and handoffPath to <checkout>/resources/content/… — the old code would have produced /private/tmp/.neo-ai-data/…. The alternate-realities split is gone; the anchor follows the checkout (= its plane), not the launch directory. The two-anchor distinction (plane anchor for plane data, neoRootDir for checkout content) is the correct taxonomy, not a convenience split.
  • Premise Coherence: Coheres with verify-before-assert (three census measurements retire the ticket's own lint prescription; the PR body says so in those words) and with the §10.5 doctrine it rides (a config default computed before the Provider exists derives from the anchor, env-free, never from ambient cwd).

🔬 Depth Floor

Challenge (non-blocking — one PMV line outruns the mechanism): the first Post-Merge Validation bullet says a future NEO_PLANE_DATA_ROOT relocation "should move the outcome file with the plane." With resolvePlaneDataRoot({env: {}, …}) — env deliberately emptied per §10.5, so the leaf machinery owns env binding — the module-scope anchor ignores NEO_PLANE_DATA_ROOT; outcomePath is a class config, not a leaf, so no env layer applies the override on top. Under a relocation the file stays at the checkout root; the actual relocation seam is Neo.create(AgentOrchestrator, {outcomePath}) (and, someday, the member-set gap your second PMV bullet names). Whoever runs that PMV check as written will file a false bug. Suggest a one-line reword when the file is next touched: "outcomePath follows the plane anchor's default; explicit relocation uses the create-time config seam — bare NEO_PLANE_DATA_ROOT does not move it (class config, no leaf env layer)." Not a cycle — the shipped default is strictly correct; the checklist line is the only place the mechanism is misstated.

Documented search (complement): I actively checked (1) the "ai/ already scanned" claim — SCAN_ROOT_REL='ai' at lint :59, plus the two A1-adjacent detectors at :281/:285/:289; (2) the env census — my own crude filter (process.env.X in ai/, spec/configBase excluded) gives 51 unique reads vs the body's 24, a methodology difference (exclusions differ), so the raw count was NOT re-derived exactly; the load-bearing intersection-of-1 claim was taken on the census's mechanism (A1 = duplicating a leaf-bound var), which is sound; (3) the class-config evaluation order claim — module-load anchor, no Provider, matching the §10.5 chicken-and-egg case; and (4) the retitle + both narrowing Deltas recorded on the ticket before opening (they are, in the comments) — and found no blocking concerns.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: divergence measurement matches my independent reproduction exactly.
  • "No lint added — the census says there is nothing to mechanize": the census numbers I could check (scan root, detector presence) hold; the intersection figure is mechanism-plausible and flagged above.
  • "The spec already exercises that seam — it injects handoffPath on every case": consistent with 18/18 green on an injected-path suite.
  • PMV bullet 1 overclaims the relocation behavior — see the challenge; prose fix, not a cycle.

Findings: one prose imprecision (PMV), recorded non-blocking.


🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: Two durable shapes here. First: a default that derives its own root is a plane member that never declared itself — invisible to both the static lint (wrong scan domain) and the runtime member-coherence assertion (walks declared members only); the defect lived exactly in the seam between two gates. Second: the census-retires-the-lint pattern — a prescription that survives contact with its own population count is rare enough to be worth the table.

N/A Audits — 📑 📡 🔗 🛂 📜

N/A across listed dimensions: one runtime file, class-config defaults only — no public contract surface, no OpenAPI, no new convention (the anchor idiom is §10.5's), no new abstraction, no authority-demand citations.


🎯 Close-Target Audit

  • Close-targets identified: Resolves #15843 (newline-isolated, body)
  • #15843 is a leaf ticket, not epic-labeled.

Findings: Pass. Both narrowings (retitle; C1 deferred to the live ADR lane) are recorded on the ticket in dated comments before the PR opened — the ledger agrees with the delivered A1 scope.


🪜 Evidence Audit

  • PR body contains an Evidence: declaration line (L2 achieved → L2 required, no residual)
  • Achieved ≥ required: the divergence is measured from two working directories — and I re-ran it on the exact head from cwd=/tmp
  • The deferred half (C1) is named explicitly with its sequencing reason, not silently dropped
  • The boot failed line in the spec output is correctly pre-flagged as a deliberate failure fixture

Findings: Pass.


🧪 Test-Evidence & Location Audit

  • Execution evidence: exact-head CI green at 7fd7ada1ac (all checks) + author receipts (18/18 specs, lint OK) + reviewer reproduction of the central divergence claim on the exact head from a foreign cwd
  • Reviewer falsifier: the cwd=/tmp probe above — the one behavior the PR exists to change, run directly
  • Test location: N/A — no spec delta (behavior covered by the existing injected-path suite, which is the correct non-duplication)

Findings: Pass.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 95 — the two-anchor taxonomy (plane anchor for plane data, repo root for checkout content) is the doctrine applied correctly, not a convenience split; the seam preservation (create-time config, env relocation) is intact.
  • [CONTENT_COMPLETENESS]: 92 — measured anti-lint defense, honest deferrals, retitle recorded; the PMV relocation line is the one prose item outrunning the mechanism (see challenge).
  • [EXECUTION_QUALITY]: 95 — central claim independently reproduced on the exact head; census spot-checks hold within methodology; exact-head CI green.
  • [PRODUCTIVITY]: 100 — the A1 scope (the ticket's surviving substance) delivered whole; both narrowings ledgered.
  • [IMPACT]: 66 — removes a silent alternate-realities writer from the plane contract's own seam; small blast radius, durable precedent for "census before gate."
  • [COMPLEXITY]: 42 — one file, but the correctness lives in the anchor doctrine and the two-gate seam analysis.
  • [EFFORT_PROFILE]: Maintenance — a bounded default correction with an unusually well-measured negative result attached.

Closing: ship it — the plane contract gets one more honest member, and the lint graveyard gets one more avoided gate.
