PR Review Summary
Status: Approved
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve
- Rationale: This is the right shape for the
#14474measurement leaf: a read-only raw-edge diagnostic, a committed live artifact, and focused hermetic coverage. The two polish findings below are not worth blocking a priority enablement PR.
Peer review of #14513: the diff is narrow, the branch is clean, and the probe gives the epic usable data without committing the follow-on architecture prematurely.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch:
#14474ticket body/labels,#14472epic label state, changed-file list, exact heada073436aa2, currentdevsibling structure viaai:structure-map, PR CI, commit log, and a Memory Core prior-art sweep for#14474/ Golden Path v2 probe context. - Expected Solution Shape: A correct leaf should read raw graph edges without writes, separate measurement from production consumption, aggregate private substrate in rendered artifacts, and pin the behavior with a hermetic unit spec. It must not close the parent epic or hardcode a production retrieval architecture.
- Patch Verdict: Matches.
ai/services/graph/conceptNeighborhoodProbe.mjskeeps the probe pure/read-side, the runner opens SQLite with{readonly: true, fileMustExist: true}, and the spec asserts raw-property visibility, bounded walking, privacy aggregation, alias clustering, and markdown output. - Premise Coherence: Coheres with V-B-A and Golden Path v2: measure the concept graph first, then let sibling leaves decide the anchoring/retrieval disposition.
🕸️ Context & Graph Linking

🔬 Depth Floor
Challenge OR documented search (per guide §7.1):
- Challenge, non-blocking: The PR summary says “zero-explanation across the entire sample,” while the committed artifact reports
Zero-explanation members: 20/22and shows two root members withEXPLAINED_BYedges. The artifact is internally truthful, so this is PR-body polish rather than a merge blocker.
Rhetorical-Drift Audit (per guide §7.4):
Findings: Pass with non-blocking polish noted above. The durable artifact and implementation make the true measurement clear.
🧠 Graph Ingestion Notes
[KB_GAP]: None.[TOOLING_GAP]: None blocking. Localgit diff --check origin/dev...HEADflags a trailing blank line at EOF in the generated measurement artifact; CI is green and this is not blocking this priority lane.[RETROSPECTIVE]: Raw-edge probing is the right primitive here: it distinguishes projection loss from storage absence and gives Golden Path v2 a measured basis for the next sibling leaves.
🎯 Close-Target Audit
- Close-targets identified: #14474
-
#14474confirmed notepic-labeled (enhancement,ai,architecture).#14472is referenced, not closed.
Findings: Pass.
📑 Contract Completeness Audit
Findings: N/A — this adds an internal diagnostic/reporting surface, not a public consumed API or wire contract.
🪜 Evidence Audit
- PR body contains an
Evidence:declaration line. - Achieved evidence matches the close-target scope: L2 unit coverage plus a committed read-only live artifact is sufficient for this measurement leaf.
Findings: Pass.
📡 MCP-Tool-Description Budget Audit
Findings: N/A — no OpenAPI tool descriptions touched.
🔗 Cross-Skill Integration Audit
Findings: N/A — no skill, MCP tool, startup substrate, or workflow convention is introduced.
🧪 Test-Execution & Location Audit
- Branch checked out locally at exact head
a073436aa2. - Canonical location: new unit spec lives under
test/playwright/unit/ai/services/graph/for the AI graph helper. - Related verification run:
npm run test-unit -- test/playwright/unit/ai/services/graph/conceptNeighborhoodProbe.spec.mjs→ 7 passed. - Current PR CI: 11/11 checks passing.
- Structure map read:
ai/services/graphandai/scripts/diagnosticsplacement verified.
Findings: Tests pass.

📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 95 — the read-only graph helper and diagnostics runner fit the currentai/services/graph+ai/scripts/diagnosticssplit; no production retrieval commitment leaks in.[CONTENT_COMPLETENESS]: 88 — JSDoc and artifact are strong; deducted for the non-blocking PR-summary overstatement and generated-artifact EOF whitespace.[EXECUTION_QUALITY]: 96 — focused unit coverage, readonly SQLite open, no graph write path, and green CI; residual risk is limited to live-data churn after the artifact timestamp.[PRODUCTIVITY]: 100 — the measurement leaf is delivered and gives the sibling leaves concrete inputs.[IMPACT]: 80 — high-value Golden Path v2 measurement substrate, but intentionally not a runtime behavior change.[COMPLEXITY]: 45 — bounded diagnostic helper plus runner and artifact; moderate because raw graph reads and privacy aggregation require care.[EFFORT_PROFILE]: Quick Win — high ROI measurement data with a constrained implementation surface.
Approved.
Resolves #14474 Refs #14472
Delivers the second measurement-floor leaf of Golden Path v2: a read-only concept-neighborhood probe (
ai/services/graph/conceptNeighborhoodProbe.mjs), its live runner (ai/scripts/diagnostics/conceptNeighborhoodProbe.mjs, readonly SQLite — zero-write is mechanical, not just contractual), a hermetic 7-test spec, and the first committed measurements artifact (learn/agentos/measurements/concept-neighborhood-probe-2026-07-02.md, 7 concepts → 22 alias-cluster members).What the live data says (the leaf's value — all three findings exceed the graduation's expectations):
golden-pathresolves to 5 aliases (the Discussion counted 4), with its structural mass split nearly evenly across two of them —CONCEPT:GoldenPath70 edges vsCONCEPT:Golden_Path80 edges, fully disjoint neighborhoods.dream-pipeline= 5 aliases; even AGENT identities fragment (×3). This is #14502's justification, quantified.EXPLAINED_BY/EXEMPLIFIED_BYedge — the gap-detection pipeline's target edge classes are absent everywhere sampled.getNeighborsprojection hid tier fields; reality: there is nothing to hide — the OQ6 contract is a to-be-materialized, which reshapes the OQ1/OQ5 dispositions (#14508's inputs).Evidence: L2 (hermetic unit spec 7/7 at head + the live readonly-store artifact committed in-diff) → L2 suffices for the close-target ACs (read-only diagnostic; no runtime behavior change). Residual: none — production consumption of the probe belongs to the gated sibling leaves [#14474].
