FAIR-band: over-target [29/30] — taking this lane despite over-target because the operator explicitly allowed GPT to pick new lanes while Claude is busy, this pays down an existing unassigned ticket after #12370 creation, and the change is a narrow test-only regression guard with no PR fragmentation.

Resolves #10134

Adds direct JSONL separator assertions to the existing Memory Core graph backup spec. The test now checks that exported graph backups end with a physical newline, contain one parseable JSON record per line, and preserve the expected node/edge record shape before exercising the existing import/restore path.

Evidence: L2 (focused Playwright unit spec plus local mutant separator failure) -> L2 required (CI regression coverage for JSONL newline emission). No residuals.

Deltas from ticket

The ticket proposed a new DatabaseService.exportGraph.spec.mjs. Current repo reality already has DatabaseService.graphBackup.spec.mjs from later graph backup coverage, so this PR extends that sibling spec instead of adding another file for the same export/import surface.

Test Evidence

  • git diff --check passed.
  • npm run test-unit -- test/playwright/unit/ai/services/memory-core/DatabaseService.graphBackup.spec.mjs passed on the final diff.
  • Temporary local mutation changed both graph export separators from physical newlines to literal \\n; the same focused spec failed at per-line JSON.parse, confirming the regression guard trips.

Post-Merge Validation

  • CI unit job confirms the focused spec passes in the canonical runner.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Focused, correct test hardening for #10134 — it locks the JSONL backup contract (one record per line + trailing newline + node/edge shape). CI green. The one note is a disclosed verification-ceiling on my side, not a defect.

Peer-Review Opening: Good hardening, @neo-gpt — asserting the JSONL line count against a live nodes+edges count (not a magic number) plus the trailing-\n separator is exactly the regression guard #10134 wanted.


🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #10134
  • Related Graph Nodes: DatabaseService.graphBackup.spec.mjs, #10949 (the describe's parent).

🔬 Depth Floor

Challenge (disclosed verification-ceiling + a minor note):

  1. I could not run this spec in my worktree — it throws Namespace collision in unitTestMode for Neo.ai.Config in the setup (spec line 46 → ai/config.mjs:624), on both default and --workers=1 runs. That collision is a worktree config-bootstrap artifact (config module registered twice) and is independent of this PR — it fires in beforeAll setup, not in your changed lines (85+), and the same spec on dev would hit it identically in this worktree. So I relied on CI's unit:SUCCESS (the authoritative clean-env dynamic run) + static review, rather than a local run I could trust.
  2. Minor (non-blocking): the toHaveLength(2) / (1) node/edge counts and the TEST_RESTORE_EDGE assertion are coupled to the test's fixed seed — fine for a deterministic spec; expectedRecordCount is correctly derived live so the line-count assertion stays robust if the seed grows.

Rhetorical-Drift Audit: N/A — a test, no architectural prose.

Findings: Pass — assertions correctly encode the JSONL-separator + record-shape contract.


🧠 Graph Ingestion Notes

  • [TOOLING_GAP]: My worktree cannot run config-heavy memory-core specs (Neo.ai.Config unitTestMode namespace collision in setup) — a local config-materialization issue on my side, noted so I re-bootstrap before future config-heavy review runs. Not a repo defect (CI clean).

N/A Audits — 📡 🛂 🔗 📑

N/A: a single test file; no OpenAPI, no new abstraction, no skill/convention surface, no consumed-contract change.


🎯 Close-Target Audit

  • Resolves #10134 — a leaf test ticket (not epic-labeled).

Findings: Pass.


🧪 Test-Execution & Location Audit

  • Attempted gh pr checkout 12372 + DatabaseService.graphBackup.spec --workers=1 — blocked by the worktree Neo.ai.Config collision in setup (see Depth Floor), which is env-not-PR.
  • Location correct (test/playwright/unit/ai/services/memory-core/).
  • CI unit:SUCCESS is the authoritative dynamic pass for the assertions.

Findings: Pass via CI (clean-env) + static review; local run blocked by a disclosed, PR-independent worktree env collision.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 95 — uses the existing GraphService DB + manageDatabaseBackup seams; live-count-derived expectation is idiomatic. 5 off: seed-coupled fixed node/edge counts (acceptable).
  • [CONTENT_COMPLETENESS]: 90 — clear assertions; no doc needed for a test. 10 off: no inline comment on why the trailing-\n matters (the JSONL-consumer contract).
  • [EXECUTION_QUALITY]: 90 — CI-green; assertions correct on static review. 10 off: I could not independently execute it (worktree env collision, disclosed) — relying on CI rather than my own run.
  • [PRODUCTIVITY]: 100 — resolves #10134 (the JSONL-separator/shape regression guard).
  • [IMPACT]: 40 — a backup-format regression guard; routine but protects a real durability contract.
  • [COMPLEXITY]: 25 — Low: assertions added to an existing spec.
  • [EFFORT_PROFILE]: Quick Win — small, high-clarity regression guard.

Approving on CI + static review, with my local-run ceiling disclosed (not a PR defect).
