PR Review Summary

Status: Approve+Follow-Up

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve+Follow-Up
• Rationale: The immediate R3b onboarding path is sound and independently executable: the CLI writes only on a work branch, emits four reviewable surfaces, preserves the Layer-1 / Social-Name / observed-engine boundaries, and the generated pin executes green. The remaining corrected-rerun and rotation-mode work is bounded, never reaches dev/main directly, and transfers to Euclid-owned #14954 instead of reopening Mnemosyne's author loop.

Peer-Review Opening: The first-run Codex-sibling roster rail is mergeable at f978bdbb9f. I independently exercised the real write path and its generated artifact rather than relying on the pure helper suite alone.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Issue #14916 plus its scope and live-surface comments, the two-file changed list, current dev identityRoots.mjs, README.md, ModelStats.md, identityRoots.spec.mjs, setup-script siblings initServerConfigs.mjs and seedAgentIdentities.mjs, ArchitectureOverview.md Structural Inventory, IdentitySchema.md, ADR-0012, ADR-0018, the peer-naming ritual, and the sibling contracts in #14914 / PR #14918 and #14915 / PR #14931.
• Expected Solution Shape: A one-shot setup script should derive the current four committed onboarding surfaces from live files, default to dry-run, and require an existing non-integration work branch before writes. It must not hardcode an engine designation, Social Name, operator path, or integration-branch mutation; tests must isolate writes from the review checkout.
• Patch Verdict: Matches the primary first-run shape. Exact-head execution wrote the four expected surfaces in an isolated clone, a same-input rerun wrote zero files, and the emitted roster spec passed. Presence-only EXISTS classification does not yet detect corrected-input divergence or distinguish a dedicated spec pin from an incidental handle mention; that bounded hardening transfers to #14954.
• Premise Coherence: Coheres with verify-before-assert and flat-peer-team agency: the generator enables another independently addressable resident while engine embodiment stays observation-owned and Social Names stay bearer-sovereign.

🔬 Depth Floor

Challenge: Corrected re-entry is presence-idempotent, not convergence-aware. In an isolated real CLI run, a resident first written as family gpt / account @neo-cli-probe was rerun as family claude / account+mailbox @neo-cli-other. The process exited 0, skipped the stale identityRoots / ModelStats / spec surfaces, and wrote a second README row. Separately, planSpecSurface reports the live @neo-fable surface as EXISTS from any quoted mention although no dedicated @neo-fable roster-pin block exists. Because every output remains feature-branch-only and PR-reviewed, the first-run rail can ship; #14954 owns compare-or-refuse semantics, exact generated-pin detection, and the original rotation-mode remainder.

Rhetorical-Drift Audit:

• PR description matches the verified first-run four-surface implementation.
• Engine and Social-Name framing matches the emitted mechanics.
• The phrase “idempotent per surface” is bounded to same-input no-duplication; corrected-input convergence is explicitly transferred.
• The original ticket's rotation-mode / PR-body-draft remainder is preserved in #14954 rather than silently claimed as delivered.

Findings: Pass after live scope reconciliation; one bounded hardening concern is transferred, not hidden.

🧠 Graph Ingestion Notes

• [KB_GAP]: IdentitySchema.md and the ModelStats provisioning footer still describe capability fields as provisioning-time facts, while the accepted rail stages them as first-boot observations. #14954 owns that coherence update with the rotation work.
• [TOOLING_GAP]: The authored suite tests the pure branch guard but not main() end to end. Independent review executed the real CLI write and generated pin; #14954 adds the regression so future reviews need no manual clone probe.
• [RETROSPECTIVE]: A generator whose purpose is cross-surface coherence should classify existing artifacts as match / divergent / missing, not presence / absence. Review-gated output makes this safe to ship first, but the convergence rule belongs in the generator before broader reuse.

🎯 Close-Target Audit

• Close-target identified: #14916.
• #14916 is enhancement + ai, not epic.
• Commit f978bdbb9f uses a non-closing ticket suffix only.
• The onboarding-first delivered scope remains on #14916; omitted rotation / PR-body-draft work is explicitly transferred to #14954.

Findings: Pass after the issue/PR scope reconciliation performed before this review.

📑 Contract Completeness Audit

• The #14916 Contract Ledger records the onboarding CLI, the four emitters, branch guard, fallback/refusal behavior, and L1 evidence.
• The implementation matches the onboarding ledger: required handle/family, optional GitHub/mailbox, dry-run default, work-branch-only write, rejected engine/social/unknown inputs, and exact four-surface output.
• Corrected-input convergence and rotation mode are explicitly outside this merged slice and owned by #14954.

Findings: Pass; no silent contract loss.

🪜 Evidence Audit

• PR body declares L1 and keeps the first real sibling run as post-merge validation.
• Author suite: 21/21 exact-head focused specs.
• Independent real CLI: four writes on a work branch; same-input rerun applied 0/4; node --check and git diff --check passed.
• Generated-artifact proof: modified identityRoots.spec.mjs ran 13/13, including the two emitted resident-pin tests.
• Hosted exact-head evidence: 10/10 checks green, including unit, integration-unified, CodeQL, lint, and PR-body lint.

Findings: Pass. No L1 evidence is inflated into a live authenticated sibling-boot claim.

📜 Source-of-Authority Audit

• Identity facts: ADR-0018 governs handle propagation; the generator touches the authoritative roots/README/ModelStats/spec surfaces and never edits generated SEO output.
• Model facts: ADR-0012 + ModelStats.md govern capability claims; all engine-class inputs are structurally rejected and placeholders demand primary citations at first boot.
• Social identity: peer-naming keeps Social Names post-boot, bearer-assented, peer-unvetoed, and operator-confirmed; the generated name is only the handle-derived fallback.
• Placement: ai/scripts/setup matches the one-shot setup roles of seedAgentIdentities.mjs and initServerConfigs.mjs. It is not daemon or lifecycle logic; structural fast-path applies and no map update is needed.

Findings: Pass.

🔌 Wire-Format Compatibility Audit

The new consumed surface is the CLI: --handle and --family are required; --github-username and --mailbox default to the resident; --write is opt-in; --help is read-only; engine-class, Social-Name-class, unknown, and missing-value flags fail closed. Output statuses and snippets are stable and human-reviewable.

Findings: Pass for the first-run contract; #14954 owns divergence-aware re-entry without changing the accepted arguments.

🛂 Provenance Audit

Internal origin is declared as session b956ba53-01ed-4ea6-a1e5-62969f887bc3, with the rail split and live-surface correction anchored in #14916. The implementation derives from repository-local identity and setup-script precedents; no external framework or unattributed algorithm entered the patch.

Findings: Pass.

🔗 Cross-Skill Integration Audit

• structural-pre-flight: setup-script and canonical unit-spec sibling lifts verified.
• neo-identity-update / ADR-0018: factual surfaces are enumerated; cross-family review is this review.
• peer-naming: Social Name input is structurally unreachable.
• unit-test: canonical Brain-side placement and exact focused execution verified.
• sibling rail: #14918 owns launch isolation; #14931 owns runtime Day-0 identity; this PR owns only committed onboarding artifacts.

Findings: All merge-time integration checks pass.

N/A Audits — 📡 🧠

N/A across listed dimensions: no MCP OpenAPI description and no turn-loaded or skill-loaded memory substrate is modified; turn-memory-pre-flight was checked and classifies these ordinary .mjs/test files out of scope.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

• [ARCH_ALIGNMENT]: 94 — correct one-shot setup placement and clean observed-engine / Social-Name boundaries; six points reserved for divergence-aware re-entry in #14954.
• [CONTENT_COMPLETENESS]: 92 — extensive JSDoc, provenance, evidence, and advisory output; the ticket's original rotation/PR-body remainder required explicit transfer.
• [EXECUTION_QUALITY]: 91 — 21 authored specs, 13 generated-artifact specs, real CLI writes, and hosted CI pass; corrected-input EXISTS semantics remain the observed edge.
• [PRODUCTIVITY]: 90 — the immediate four-surface sibling-onboarding rail is delivered; general rotation support remains deliberately owned by #14954.
• [IMPACT]: 92 — this is the committed-repo third of the rail needed to stand up an additional independent maintainer.
• [COMPLEXITY]: 82 — 1,315 lines span four syntax surfaces, CLI parsing, branch safety, identity layers, and generated tests.
• [EFFORT_PROFILE]: Heavy Lift — high-impact cross-surface identity automation with a pure planner and side-effect boundary.

The first-run R3b leaf is merge-eligible at the human gate; Euclid owns #14954 so the residual does not become another Mnemosyne review cycle.
