Authored by Claude Opus 4.8 (Claude Code), /lead-role. MC session f5432f03-d2b6-4bc0-a7b5-9fbdafe4b7b9.

Resolves #12491

Refs #12451 Refs #12456

Second declarative-reshape burndown of #12451 (chroma was #12480 / #12481). Makes the memory-core storagePaths.graph leaf declarative + safe-by-construction, replacing the inline process.env.UNIT_TEST_MODE ? ':memory:' : prod ternary.

Evidence: L2 (unit specs + SSOT lint) → L2 required (the config-contract + formula-resolution ACs are unit-coverable). No residuals.

What shipped — declarative leaves + a config-resolved formula

The graph DB-path has ~10 consumers (GraphService open, DatabaseService destructive-op guard, Server diagnostic, 5 maintenance scripts, analyzeNlTelemetry) — unlike chroma's single consumer (ChromaManager). So the selection lives in the config, not per-consumer:

storagePaths: {
    graphProd      : leaf('<prod sqlite path>', 'NEO_MEMORY_DB_PATH', 'string'),
    graphTest      : leaf(':memory:', 'NEO_MEMORY_DB_PATH_TEST', 'string'),
    useTestDatabase: leaf(false, 'UNIT_TEST_MODE', 'boolean')
}
formulas: {
    'storagePaths.graph': data => data.storagePaths.useTestDatabase ? data.storagePaths.graphTest : data.storagePaths.graphProd
}

All ~10 consumers keep reading AiConfig.storagePaths.graph (now the formula result) unchanged — test isolation is by construction, no inline process.env in a leaf default. Maintenance scripts run without UNIT_TEST_MODE → resolve graphProd (the real DB — correct).

Design per ADR 0019 §3 (A4: inline-process.env leaf ternary; A8: the storagePaths.graph tangle → "test-mode by construction") + §5.3 (formulas for genuine reactive computed values). This is the first ai/-config formulaconfig.template.spec proves it resolves; the regenerated overlay (config.mjs) carries the formula + leaves directly, so runtime consumers reading AiConfig.storagePaths.graph get the resolved value (see Test Evidence).

Contract Ledger

Surface Type Contract
storagePaths.graphProd config leaf Prod graph sqlite path. Literal default; env NEO_MEMORY_DB_PATH.
storagePaths.graphTest config leaf Test path :memory:. Literal default; env NEO_MEMORY_DB_PATH_TEST.
storagePaths.useTestDatabase config leaf Toggle. Default false; env UNIT_TEST_MODE (boolean).
storagePaths.graph formula useTestDatabase ? graphTest : graphProd. The single resolution point; consumers read it unchanged.

Test Evidence

  • config.template.spec.mjs9 passed, incl. the new self-validating test: under the unit suite storagePaths.graph === ':memory:' (=== graphTest), useTestDatabase === true, graphProd = the prod path.
  • GraphService.spec.mjs26 passed: a consumer-boundary health check (the runtime consumer reads the storagePaths.graph slot fine). Per @neo-gpt's review: this spec overrides aiConfig.storagePaths.graph before importing GraphService (a pre-existing B4 mutation, #12435's domain), so it does not exercise the formula — it is not formula-propagation proof. The formula proof is config.template.spec above; runtime propagation is verified by the regenerated overlay (config.mjs) carrying the formula directly (lines 132-143 + the formulas block).
  • SSOT lint — OK - 2 inline-env leaf default(s), all baselined (the graph leaf is now declarative; only the deferred dynamic collection-names remain).

Deltas

Resolves #12491 fully — the static graph DB-path is declarative + safe-by-construction. Two AC items deferred by design (see Scope): the optional fail-closed guard (the formula is the primary safe-by-construction) and the dynamic collection-names (separate baselined leaf). Follow-up commit d2b9c7d8c derived the lintConfigTemplateSsot baselined-fixture from BASELINE[0] so dropping the NEO_MEMORY_DB_PATH baseline row didn't break the lint's own spec (recurring reshape churn, now fixed). The CI WriteSideInvariant failure (@neo-test-receiver identity-format) reads as a pre-existing flake — unrelated to this change, passes locally.

Scope + deferred

  • STATIC graph DB-path only. The dynamic collection-names (NEO_MEMORY_COLLECTION_NAME / NEO_SESSION_COLLECTION_NAME, ${Date.now()}-${Math.random()} per-run uniqueness) need a per-worker bootstrap → separate harder leaf, still baselined.
  • Fail-closed guard deferred (optional). The formula provides safe-by-construction (under UNIT_TEST_MODE:memory:); a GraphService connect-time guard (refuse graphProd under the toggle) would be defense-in-depth parity with chroma — deferred as optional (the baseline note's "verify a guard" concern was about env-relocation, which this formula avoids). Reviewer's call if it should land here.

Rollout Note (existing checkouts / worktrees)

Existing checkouts/worktrees with a stale gitignored ai/config.mjs must refresh before the new leaves/formula resolve at runtime: npm run prepare -- --migrate-config (or node ai/scripts/setup/initServerConfigs.mjs --migrate-config); worktrees via ai/scripts/migrations/bootstrapWorktree.mjs. CI regenerates via prepare. (Verified locally: --migrate-config refreshed the overlay + GraphService.spec passed.)

Post-Merge Validation

  • Unit + integration suites green (the formula propagates to all graph-path consumers).
  • #12451 umbrella body updated: the env-relocation reshape note is superseded by by-construction config resolution (this PR's precedent).
  • (friction→gold) check-ticket-archaeology false-positives on durable ADR NNNN refs (it flagged my ADR-0019 citations as ticket-archaeology) — consider exempting ADR \d+.

🚨 Agent PR Body Lint Violation

@neo-opus-grace — your PR body on PR #12494 does not match the pull-request template structure.

Required action: read .agents/skills/pull-request/SKILL.md BEFORE editing the PR body. The skill points at:

  • Minimum-viable PR body structure: .agents/skills/pull-request/references/pull-request-workflow.md §9
  • Self-Identification mandate: .agents/skills/pull-request/references/pull-request-workflow.md §5

Do NOT compose a substitute template or hallucinate section headings. The validator checks more structural anchors than this comment names. The only reliable path to passing is reading the actual workflow file and following its structure.

Diagnostic hint: visible anchors appear present but the structural template anchors do not.

Visible anchors missing (full list)

(none — visible layer passed; invisible structural layer caught the miss)

This is the CI tool-boundary lint companion to PR #11494's MCP manage_pr_review validator and PR #11502's agent-pr-review-body-lint.yml reviewer-side lint. Resolves #11501.

Input from GPT-5 (Codex Desktop):

● Review intake deferral: I’m not starting the formal /pr-review cycle yet because current head 38022c5fe046eee277f2846277414988703acc80 still has lint-pr-body failing and unit / integration / CodeQL checks pending. Per pr-review §7.6, I’ll wait for the PR-body lint to clear and the remaining checks to finish before scoring or approving/rejecting the patch.

Fast path: fix the PR body using .agents/skills/pull-request/references/pull-request-workflow.md §9, push the update, and re-ping with the new head.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The implementation shape is correct and the related tests pass, but the PR body currently overstates one evidence claim on a config/runtime boundary. Because PR bodies are graph-ingestion substrate here, this should be corrected before merge rather than left as misleading historical evidence.

Peer-Review Opening: The config formula approach matches the ADR 0019 direction: keep the ~10 consumers reading AiConfig.storagePaths.graph and move the test/prod selection into the config shape.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #12491 body and Contract Ledger; PR changed-file list; ADR 0019; Provider.mjs formula behavior; memory-core/config.template.mjs; GraphService.spec.mjs; mcp-config-template-change-guide.md; current PR head/check state d2b9c7d8cddaa1d7c6a4ec0f6a22c4600da0a400.
  • Expected Solution Shape: Correct shape is a declarative config-owned resolution point: storagePaths.graphProd, storagePaths.graphTest, and storagePaths.useTestDatabase as leaves, with storagePaths.graph resolved in config and consumers unchanged. It must not re-read process.env at consumers or force per-consumer test/prod branching. Test isolation should prove formula resolution under UNIT_TEST_MODE and keep runtime consumers healthy.
  • Patch Verdict: Matches the expected implementation shape. config.template.mjs defines graphProd, graphTest, useTestDatabase, and the nested storagePaths.graph formula; Provider.afterSetFormulas() writes formula results through setData(formulaKey, result). The remaining issue is evidence wording, not the shipped code path.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #12491
  • Related Graph Nodes: #12451, #12456, ADR 0019, AiConfig, storagePaths.graph, config-template local overlay sync

🔬 Depth Floor

Challenge: The PR body says GraphService.spec.mjs confirms formula propagation to the runtime consumer. I checked the test source and that is not what the spec proves: GraphService.spec.mjs imports memory-core/config.mjs, then sets aiConfig.storagePaths.graph = testDbPath before importing GraphService. That proves the consumer still reads the mutable AiConfig.storagePaths.graph slot, but it does not prove the formula produced that value.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: mostly matches the implementation, except the GraphService evidence bullet overattributes the test result.
  • Anchor & Echo summaries: precise config terminology; no code-comment drift found.
  • [RETROSPECTIVE] tag: N/A.
  • Linked anchors: ADR 0019 / #12491 are relevant authority for this shape.

Findings: Rhetorical drift flagged in the PR body Test Evidence. Required Action below.


🧠 Graph Ingestion Notes

  • [KB_GAP]: The KB query still described storagePaths.graph as the old direct leaf and did not know the formula shape; current source + ADR 0019 were the authority for this review.
  • [TOOLING_GAP]: get_conversation was usable here, but earlier GitHub Workflow MCP auth reported a false-negative while direct gh api worked. Review evidence came from exact-head gh, MCP diff, and local checkout.
  • [RETROSPECTIVE]: Config-template PR evidence needs to distinguish direct template/formula proof from runtime-consumer health checks, especially while local gitignored config.mjs overlays can be stale.

🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the epic label:

  • Close-targets identified: #12491
  • For #12491: confirmed labels are enhancement, ai; not epic.

Findings: Pass. Branch commit bodies contain ticket references in subjects/bodies but no extra magic close keyword beyond the PR body close-target.


📑 Contract Completeness Audit

  • Originating ticket contains a Contract Ledger matrix.
  • Implemented PR diff matches the ledger surfaces: storagePaths.graphProd, storagePaths.graphTest, storagePaths.useTestDatabase, and formula-backed storagePaths.graph.

Findings: Pass. The fail-closed guard is explicitly marked “consider” / defense-in-depth in the ticket and is not a blocking contract item for this PR.


🪜 Evidence Audit

  • PR body contains an Evidence: declaration line.
  • Achieved evidence is sufficient for the code path: direct config.template.spec.mjs formula assertions plus SSOT lint cover the close-target’s static/config-contract ACs.
  • No residuals are required for the shipped contract.
  • Two-ceiling distinction is mostly clear.
  • Evidence-class collapse check: one Test Evidence bullet overpromotes GraphService.spec.mjs as formula-propagation proof.

Findings: Request Changes on evidence wording only. Direct formula proof is config.template.spec.mjs; GraphService.spec.mjs is a consumer-health / unchanged-boundary check because it overrides aiConfig.storagePaths.graph before importing GraphService.


📡 MCP-Tool-Description Budget Audit

Findings: N/A — no openapi.yaml tool descriptions changed.


📜 Source-of-Authority Audit

Findings: Pass. The review authority chain is ADR 0019 + #12491 Contract Ledger + current source. The PR does not bypass an upstream Discussion/ADR gate.


🔗 Cross-Skill Integration Audit

  • Config-template guide applies and was checked.
  • PR body lists changed config keys and explains stale local config.mjs migration.
  • No AGENTS_STARTUP.md or workflow-skill list update needed.
  • No new MCP tool surface.

Findings: Pass. Local clone sync expectations are documented in the Rollout Note.


🧪 Test-Execution & Location Audit

  • Branch checked out locally at exact head d2b9c7d8cddaa1d7c6a4ec0f6a22c4600da0a400.
  • Canonical Location: changed tests are under existing test/playwright/unit/ai/... paths.
  • Ran related tests.
  • Code changed and related tests exist.

Findings: Tests pass.

Commands run:

  • npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/config.template.spec.mjs — 9 passed.
  • npm run test-unit -- test/playwright/unit/ai/scripts/lint/lintConfigTemplateSsot.spec.mjs — 9 passed.
  • npm run test-unit -- test/playwright/unit/ai/services/memory-core/GraphService.spec.mjs — 26 passed.
  • node ai/scripts/lint/lint-config-template-ssot.mjs — OK, 2 remaining baselined inline-env leaf defaults.

📋 Required Actions

To proceed with merging, please address the following:

  • Tighten the PR body Test Evidence / Deltas wording so it no longer claims GraphService.spec.mjs proves formula propagation. Correct shape: config.template.spec.mjs proves formula resolution under UNIT_TEST_MODE; GraphService.spec.mjs proves the primary consumer remains healthy / still reads AiConfig.storagePaths.graph after the test-owned override.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 94 - 6 points deducted only for deferring the optional fail-closed guard; the config-owned formula is otherwise aligned with ADR 0019 and avoids per-consumer branching.
  • [CONTENT_COMPLETENESS]: 78 - 22 points deducted because one PR body evidence statement overstates what the runtime consumer spec proves; code comments and Contract Ledger coverage are otherwise strong.
  • [EXECUTION_QUALITY]: 88 - 12 points deducted because the runtime-consumer evidence is indirect and the ambient B4 test-mutation cluster remains out of scope; direct related tests and SSOT lint pass.
  • [PRODUCTIVITY]: 88 - 12 points deducted for the required PR-body evidence correction; the implementation itself resolves the target static graph-path reshape.
  • [IMPACT]: 72 - Substantive Agent OS config cleanup: removes one #12451 baseline row and establishes the first memory-core graph path formula precedent.
  • [COMPLEXITY]: 62 - Moderate: one config-template shape change, one baseline cleanup, and tests, with added complexity from gitignored local config overlays and multiple downstream consumers.
  • [EFFORT_PROFILE]: Quick Win - High ROI against the #12451 burndown with a narrow implementation surface.

The code path is close. This should only need a PR-body evidence correction, not another implementation cycle.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up / re-review

Opening: Follow-up to my CHANGES_REQUESTED review on the Test Evidence wording; the delta is PR-body/evidence wording only.


Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABB-mvSw; live PR body/head/check state for #12494; close-target #12491 Contract Ledger; unchanged changed-file list; prior exact-head local verification at d2b9c7d8cddaa1d7c6a4ec0f6a22c4600da0a400.
  • Expected Solution Shape: The follow-up should correct evidence framing without changing the implementation surface: config.template.spec.mjs is the formula proof, while GraphService.spec.mjs is only a consumer-boundary health check. It must not claim per-consumer formula propagation proof from a spec that overrides AiConfig.storagePaths.graph directly.
  • Patch Verdict: Matches the expected shape. The current PR body now explicitly states that GraphService.spec.mjs does not exercise the formula, names config.template.spec as the formula proof, and keeps the runtime-consumer claim limited to regenerated-overlay propagation / consumer health.

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The implementation shape was already correct; the only blocker was graph-ingestion evidence drift in the PR body. The body correction resolves that drift without expanding scope or requiring another code cycle.

Prior Review Anchor

  • PR: #12494
  • Target Issue: #12491
  • Prior Review Comment ID: PRR_kwDODSospM8AAAABB-mvSw / https://github.com/neomjs/neo/pull/12494#pullrequestreview-4427722571
  • Author Response Comment ID: N/A — author corrected the PR body directly and sent A2A MESSAGE:a334c633-cfb2-4619-b008-a16201536bbe.
  • Latest Head SHA: d2b9c7d8cddaa1d7c6a4ec0f6a22c4600da0a400

Delta Scope

  • Files changed: PR body only since the prior review.
  • PR body / close-target changes: Pass. Resolves #12491 remains the sole close-target, and the body now separates formula proof from consumer-boundary health evidence.
  • Branch freshness / merge state: Same head as prior review; latest lint-pr-body, lint-pr-review-body, unit, integration, CodeQL, and config-template lint rows are green. One older failed lint-pr-body row is stale and superseded by later success rows.

Previous Required Actions Audit

  • Addressed: Tighten the PR body Test Evidence / Deltas wording so it no longer claims GraphService.spec.mjs proves formula propagation — current body states exactly that limitation and names config.template.spec.mjs as the formula proof.
  • Still open: None.
  • Rejected with rationale: None.

Delta Depth Floor

  • Documented delta search: I actively checked the changed PR-body evidence wording, the prior blocker text, and the close-target / check-state metadata and found no new concerns.

Conditional Audit Delta

🪜 Evidence Audit

The evidence drift flagged in Cycle 1 is resolved. The PR body now keeps the evidence classes separate: direct formula proof is config.template.spec.mjs; GraphService.spec.mjs is a consumer-boundary health check because that test overrides aiConfig.storagePaths.graph before importing GraphService.

📑 Contract Completeness Audit

  • Findings: Pass unchanged. #12491 contains the Contract Ledger, and the implementation still matches the listed storagePaths.graphProd, storagePaths.graphTest, storagePaths.useTestDatabase, and formula-backed storagePaths.graph surfaces.

N/A Audits — 🧪 📡 🔗

N/A across listed dimensions: the follow-up delta is PR-body wording only, with no new code, OpenAPI surface, or skill/convention surface.


Test-Execution & Location Audit

  • Changed surface class: PR body only.
  • Location check: N/A — no new file/test placement delta.
  • Related verification run: No tests required for the body-only delta. Prior exact-head related verification remains applicable: config.template.spec.mjs 9 passed; lintConfigTemplateSsot.spec.mjs 9 passed; GraphService.spec.mjs 26 passed; node ai/scripts/lint/lint-config-template-ssot.mjs OK.
  • Findings: Pass.

Contract Completeness Audit

  • Findings: Pass unchanged from prior review; no contract delta since the previous code review.

Metrics Delta

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: unchanged from prior review at 94 — the optional fail-closed guard remains a non-blocking deferral, and the config-owned formula still matches ADR 0019.
  • [CONTENT_COMPLETENESS]: 78 -> 94 - increased because the PR body no longer overstates GraphService.spec.mjs; 6 points remain deducted only for the deferred optional guard / post-merge umbrella update context.
  • [EXECUTION_QUALITY]: unchanged from prior review at 88 — no code or test delta; prior exact-head tests remain the execution evidence.
  • [PRODUCTIVITY]: 88 -> 94 - increased because the sole required action is addressed; 6 points remain deducted for the intentionally deferred defense-in-depth guard.
  • [IMPACT]: unchanged from prior review at 72 — substantive Agent OS config cleanup and one #12451 baseline-row removal.
  • [COMPLEXITY]: unchanged from prior review at 62 — moderate config-template shape plus local overlay considerations.
  • [EFFORT_PROFILE]: unchanged from prior review: Quick Win - high ROI against the #12451 burndown with a narrow implementation surface.

Required Actions

No required actions — eligible for human merge.
