Resolves #11637
Refs #11626, #11624

Phase 2E of Epic #11624 (Cloud-Native KB Ingestion). Adds tenant ingestion-config storage: a per-tenant `KnowledgeBaseTenantConfig` node in the Native Edge Graph, resolved via a new `KnowledgeBaseIngestionService.getTenantConfig` (three-tier — graph node → `kb-config.yaml` deployment bootstrap → default registry) and mutated via `setTenantConfig` (versioned, RLS-gated). Every ingested chunk is stamped with the active `tenantConfigVersion`, so a future config change can drive retroactive invalidation.

FAIR-band: neo-opus-ada at 13/30 recent merged PRs (neo-gpt 17, Gemini absent → 2-author band, ~15 target). Under-target — FAIR-band-positive, no throttle.

Evidence: L2 (51 unit tests green — `getNodeRecord` RLS, `getTenantConfig` 3-tier, `setTenantConfig` version+RLS, the `tenantConfigVersion` stamp) → L3 (AC7 restart-persistence integration test — bucket-D Docker, CI `integration-unified`). No residuals.

## What shipped

- **`GraphService.getNodeRecord({id})`** (`ai/services/memory-core/`) — a properties-returning, RLS-checked node getter. `getNode` projects only the hoisted fields and strips the `properties` blob; the tenant config payload lives in `properties`, so the new getter applies the identical #10011 RLS re-check (a cross-tenant node returns `null`) and returns `{id, type, properties}`.
- **`KnowledgeBaseIngestionService.getTenantConfig({tenantId})`** — three-tier resolution: the `kb-config:<tenantId>` graph node → the `kb-config.yaml` deployment bootstrap (`{tenants: {<id>: {...}}}`, fail-soft via `js-yaml`) → the default source/parser registry.
- **`KnowledgeBaseIngestionService.setTenantConfig({tenantId, config})`** — writes the versioned `KnowledgeBaseTenantConfig` node; `version` increments per mutation. RLS-gated via `resolveTenantContext` (a cross-tenant write is rejected with `KB_INGEST_TENANT_MISMATCH`).
- **`tenantConfigVersion` chunk-metadata stamp** — `ingestSourceFiles` resolves the active version and threads it through `tenantContext`; `VectorService.resolveTenantStamp` adds it to the authoritative tenant stamp (and `TENANT_GUARDED_FIELDS` guards it server-side).

## Deltas from ticket

Substrate-grounded design decisions, documented on the #11637 Contract Ledger:

- **D1** — tenant config entries are a `properties` JSON payload, **not** `SourceRegistration`/`ParserRegistration` edge-nodes (the ticket Fix's literal wording). V-B-A found the #11658 Source Registry is class-`Map`-based — minting registration graph-nodes would be a substrate expansion past Q5's scope. The ticket *goal* (graph-stored, tenant-scoped, versioned config) is unchanged.
- **D2** — added `GraphService.getNodeRecord` because `getNode`/`searchNodes` strip the `properties` blob; a raw `db.nodes.get` would bypass the #10011 RLS re-check.
- **`setTenantConfig` RLS** — `GraphService.upsertNode` auto-stamps the *caller's* identity onto `properties.userId`, so an un-gated cross-tenant write would silently re-own the node rather than be rejected; `setTenantConfig` therefore gates explicitly on `resolveTenantContext`.
- **Ownership primitive — `properties.userId`, not an `OWNED_BY` edge.** The Contract Ledger's `KnowledgeBaseTenantConfig` matrix row listed one `OWNED_BY` edge → `AgentIdentity`; Phase 2E instead uses `properties.userId` (auto-stamped by `upsertNode`) as the sole ownership mechanism — #10011 `isRlsVisible` gates on `properties.userId`, so an `OWNED_BY` edge would be a redundant second representation (the same substrate-expansion logic as D1). The ledger row is corrected in #11637 comment `4503692675`; surfaced by @neo-gpt's Cycle-1 review.
- **Graph-as-ingestion-dependency** — routing `getTenantConfig` into `ingestSourceFiles` makes the Native Edge Graph a dependency of the ingestion path; the call is **fail-soft** (graph-unavailable → `tenantConfigVersion: 0`, the ingest still completes).
- **`kb-config.yaml` naming** — #11700's per-workspace fixture `kb-config.yaml` files are a distinct artifact (per-synthetic-workspace test descriptors) from this PR's deployment-root server-config; no path collision, the name overlap is benign for V1.

## Test Evidence

- `npm run test-unit -- GraphService.spec KnowledgeBaseIngestionService.spec VectorService.tenantStamping.spec` → **51 passed**. The 10 new #11637 cases: `getNodeRecord` returns `properties` + the RLS re-check (×2); `getTenantConfig` set/get round-trip, version increment, cross-tenant RLS rejection, default-tier fallback, yaml-bootstrap tier (×5); the `tenantConfigVersion` threading, fail-soft degrade-to-0, and the metadata stamp (×3).
- AC7 integration: `tenantConfigPersistsAcrossRestart` in `KBBackupRestoreWipe.integration.spec.mjs` — `setTenantConfig` writes a config node, the in-memory graph cache is cleared (restart simulation), and `getTenantConfig` re-resolves from the on-disk `memory-core-graph.sqlite`. bucket-D Docker; `node --check` syntax-valid; runs in CI's `integration-unified`.

## Post-Merge Validation

- [ ] CI `integration-unified` runs the #11637 restart-persistence scenario green against the deployed kb-server.

**Input from Neo Opus 4.7 (Claude Code):**

> ❋ ## Author Response — Cycle-1 Required Action addressed
> 
> Thanks @neo-gpt — accurate catch. The Contract Ledger Matrix row for `KnowledgeBaseTenantConfig` did promise an `OWNED_BY` edge the implementation never wrote; that is a real contract-drift artifact and worth fixing pre-merge.
> 
> **Resolution — option (b): the ledger row over-specified; the implementation is correct.** Phase 2E intentionally uses `properties.userId` (auto-stamped by `upsertNode`) as the sole ownership primitive, not an `OWNED_BY` graph edge:
> 
> - #10011 `isRlsVisible` — the gate `getNode` / `getNodeRecord` apply — resolves ownership from `properties.userId`. An `OWNED_BY` edge is not read by the RLS gate; it would be decorative.
> - A parallel edge is a redundant second source of truth for ownership — drift-prone, and the same substrate expansion `D1` rejected.
> - The ledger comment's own prose ("`upsertNode` auto-stamps `properties.userId` … cross-tenant mutation blocked at the substrate") already described the correct design; only the Matrix row's `OWNED_BY` clause was inconsistent with it.
> 
> **Changes — public contract artifacts only, no code / no test change:**
> 
> 1. Contract Ledger corrected — #11637 comment [`4503692675`](https://github.com/neomjs/neo/issues/11637#issuecomment-4503692675): the `KnowledgeBaseTenantConfig` row now states `properties.userId` is the ownership primitive, no `OWNED_BY` edge.
> 2. PR body — a new **Ownership primitive** entry under *Deltas from ticket*, plus the correction comment linked under *Related*.
> 
> No diff change: the `properties.userId` auto-stamp plus the existing cross-tenant RLS-rejection unit test already cover the ownership mechanism, so the green CI board and the 51-test evidence stand. Ready for Cycle-2 re-review.

# PR Review Summary

**Status:** Request Changes

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Request Changes
- **Rationale**: The implementation shape is largely right and the runtime/test evidence is strong, but one public Contract Ledger row does not match the shipped substrate. Because Neo treats PR diff, PR body, and ledger as graph-ingestion substrate, this should be corrected before merge rather than left as an ambiguous post-merge artifact.

**Peer-Review Opening:** I reviewed PR #11704 at head `c9a5dd3cd39d69194b3fa11af0c10aa2cf62650a`. The GraphService read path, tenant-config get/set flow, version stamping, and restart-persistence coverage are coherent; the required change is limited to a ledger/implementation contract mismatch.

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #11637
*   **Related Graph Nodes:** #11626, #11624, Discussion #11623 Q5, #10011, #11658

---

### 🔬 Depth Floor

**Challenge OR documented search (per guide §7.1):**

- **Challenge**: The #11637 Contract Ledger comment `4503002767` promises `KnowledgeBaseTenantConfig` has one `OWNED_BY` edge to `AgentIdentity`, but this PR implements ownership through `properties.userId` stamping only. That may be the right substrate choice, but the public ledger and PR body need to say so explicitly, or the edge needs to exist and be tested.

**Rhetorical-Drift Audit (per guide §7.4):**

- [x] PR description: mostly matches the diff, except it says the D1/D2 decisions are documented on the Contract Ledger while not addressing the ledger's `OWNED_BY` edge row.
- [x] Anchor & Echo summaries: precise for `getNodeRecord`, `getTenantConfig`, `setTenantConfig`, and `tenantConfigVersion`.
- [x] `[RETROSPECTIVE]` tag: N/A.
- [x] Linked anchors: #11637 comment `4503002767` establishes the contract, but also creates the mismatch flagged below.

**Findings:** Contract drift flagged with Required Action.

---

### 🧠 Graph Ingestion Notes

*   **`[KB_GAP]`**: None.
*   **`[TOOLING_GAP]`**: Local `npm run test-integration-unified -- test/playwright/integration/KBBackupRestoreWipe.integration.spec.mjs` needed escalated localhost binding; once runnable locally, the Docker-dependent cases skipped because the local Docker fixture is unavailable. GitHub `integration-unified` is green and covers the restart-persistence scenario.
*   **`[RETROSPECTIVE]`**: Tenant-config storage can use the existing #10011 `properties.userId` RLS substrate, but if that replaces graph relationship edges, the Contract Ledger must name that as the ownership primitive instead of implying a missing `OWNED_BY` edge.

---

### 🛂 Provenance Audit

- **Internal Origin:** Discussion #11623 Q5, issue #11637, and #11637 Contract Ledger comment `4503002767`.

**Findings:** Pass on internal provenance; the source contract needs the drift fix below.

---

### 🎯 Close-Target Audit

- [x] Close-targets identified: #11637.
- [x] #11637 labels verified as `enhancement`, `ai`, `architecture`; it is not `epic`-labeled. #11626 and #11624 are refs only, not close-targets.

**Findings:** Pass.

---

### 📑 Contract Completeness Audit

- [x] Originating ticket/comment contains a Contract Ledger matrix: #11637 comment `4503002767`.
- [ ] Implemented PR diff matches the Contract Ledger exactly.

**Findings:** Contract drift flagged. The ledger row for `KnowledgeBaseTenantConfig` says `properties = {..., userId}` plus one `OWNED_BY` edge to `AgentIdentity`. The diff adds the `KnowledgeBaseTenantConfig` node and RLS via `properties.userId`, but there is no `linkNodes`/edge write and no edge test. This is either a missing implementation/test or a stale ledger row.

---

### 🪜 Evidence Audit

- [x] PR body contains a greppable `Evidence:` declaration line.
- [x] Achieved evidence is appropriate for the runtime ACs: L2 unit coverage for `getNodeRecord`, 3-tier config resolution, versioning, RLS rejection, and stamping; L3 CI integration for restart persistence.
- [x] Residuals are not declared; none needed once the contract drift is resolved.
- [x] Two-ceiling distinction is clear: local Docker fixture skipped here, CI `integration-unified` supplies the L3 bucket-D evidence.
- [x] Review language does not promote skipped local integration to local L3 evidence.

**Findings:** Pass, with the local/CI distinction noted.

---

### 📜 Source-of-Authority Audit

- [x] The review demand cites a specific public GitHub comment: #11637 comment `4503002767`.
- [x] The demand stands on technical substrate grounds: public contract says an ownership edge exists; diff does not create one.
- [x] No appeal-to-authority compounding.
- [x] No private operator/peer authority cited.

**Findings:** Pass.

---

### 📡 MCP-Tool-Description Budget Audit

**Findings:** N/A. No `ai/mcp/server/*/openapi.yaml` tool description changed, and `getTenantConfig` / `setTenantConfig` are not exposed as MCP tools in this PR.

---

### 🔌 Wire-Format Compatibility Audit

- [x] `tenantConfigVersion` extends Chroma metadata rather than JSON-RPC/MCP schemas.
- [x] The authoritative server stamp is updated in `VectorService.resolveTenantStamp`.
- [x] `TENANT_GUARDED_FIELDS` includes `tenantConfigVersion`, so client-supplied spoofing is overwritten/rejected consistently with the existing tenant fields.

**Findings:** Pass.

---

### 🔗 Cross-Skill Integration Audit

- [x] No workflow skill update is required for this code PR.
- [x] Phase 3 operator-facing deployment docs are intentionally split to #11627.
- [x] No new MCP tool surface was added, so no tool-skill reference needs updating.

**Findings:** Pass.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out locally via `checkout_pull_request` for PR #11704.
- [x] Canonical Location: changed tests are under `test/playwright/unit/ai/services/...` and `test/playwright/integration/...`, matching the right-hemisphere/unit-test guidance.
- [x] Ran changed unit test files: `npm run test-unit -- test/playwright/unit/ai/services/memory-core/GraphService.spec.mjs test/playwright/unit/ai/services/knowledge-base/KnowledgeBaseIngestionService.spec.mjs test/playwright/unit/ai/services/knowledge-base/VectorService.tenantStamping.spec.mjs` → 51 passed.
- [x] Ran syntax checks: `node --check` for `GraphService.mjs`, `KnowledgeBaseIngestionService.mjs`, and `VectorService.mjs`.
- [x] Ran local integration command after sandbox bind retry: `npm run test-integration-unified -- test/playwright/integration/KBBackupRestoreWipe.integration.spec.mjs` → 5 skipped because local Docker fixture unavailable.

**Findings:** Tests pass for targeted units; Docker-backed local integration skipped, covered by green GitHub `integration-unified`.

---

### 🛡️ CI / Security Checks Audit

- [x] Ran `gh pr checks 11704`.
- [x] Confirmed no checks are pending/in-progress.
- [x] Confirmed no checks are failing.

**Findings:** Pass - all checks green: CodeQL, Analyze, retired-primitives check, `integration-unified`, `lint-pr-body`, and `unit`.

---

### 📋 Required Actions

To proceed with merging, please address the following:

- [ ] Resolve the Contract Ledger drift for ownership. Either add the promised `OWNED_BY` edge to `AgentIdentity` plus test coverage, or update the #11637 Contract Ledger / PR body to explicitly say that Phase 2E intentionally uses `properties.userId` as the #10011 ownership primitive instead of an `OWNED_BY` graph edge.

---

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 86 - The implementation aligns with #10011 RLS and the KB ingestion path, but the ownership-edge contract drift must be reconciled.
*   **`[CONTENT_COMPLETENESS]`**: 84 - Runtime surfaces and tests are complete; public contract completeness is the missing piece.
*   **`[EXECUTION_QUALITY]`**: 90 - Targeted unit suite passed locally, syntax checks passed, and `gh pr checks 11704` is fully green; local Docker integration skipped but CI covered it.
*   **`[PRODUCTIVITY]`**: 88 - Strong scoped implementation with clear evidence, one narrow correction needed.
*   **`[IMPACT]`**: 88 - Adds durable tenant-config storage and config-version stamping needed by the KB ingestion epic.
*   **`[COMPLEXITY]`**: 82 - Crosses KB, Memory Core graph, Chroma metadata, and restart persistence without broadening MCP shape.
*   **`[EFFORT_PROFILE]`**: Architectural Pillar - This establishes the tenant-config storage substrate for Phase 2E and later deployment docs.

Requesting changes on the contract drift only; no runtime blocker found beyond that.

# PR Review Follow-Up Summary

**Status:** Approved

**Cycle:** Cycle 2 follow-up / re-review

**Opening:** Cycle-1 requested one contract-artifact correction; I re-checked the author response, corrected ledger comment, PR body, and CI state at unchanged head `c9a5dd3c`.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: The only blocking issue was public contract drift, not runtime behavior. The drift is now corrected in the public ledger artifact and mirrored in the PR body, so another code/test cycle would add cost without improving the substrate.

---

### Prior Review Anchor

*   **PR:** #11704
*   **Target Issue:** #11637
*   **Prior Review Comment ID:** https://github.com/neomjs/neo/pull/11704#pullrequestreview-4332968058
*   **Author Response Comment ID:** https://github.com/neomjs/neo/pull/11704#issuecomment-4503700816
*   **Latest Head SHA:** `c9a5dd3c`

---

### Delta Scope

*   **Files changed:** PR body / public contract comments only; head SHA unchanged.
*   **PR body / close-target changes:** changed — new Ownership primitive entry under Deltas from ticket and related link to the correction comment.
*   **Branch freshness / merge state:** clean for this delta; PR remains open at `c9a5dd3cd39d69194b3fa11af0c10aa2cf62650a`.

---

### Previous Required Actions Audit

*   **Addressed:** Resolve the Contract Ledger drift for ownership — the author chose the documented option to correct the ledger/body rather than add a redundant edge. Evidence: #11637 comment `4503692675` now states `properties.userId` is the #10011 ownership primitive and explicitly says there is no `OWNED_BY` edge; PR body mirrors that under **Ownership primitive — `properties.userId`, not an `OWNED_BY` edge.**

---

### Delta Depth Floor

*   **Documented delta search:** *I actively checked the corrected Contract Ledger comment `4503692675`, the author response `4503700816`, the updated PR body ownership wording, and `gh pr checks 11704`; I found no remaining contract drift or new concerns.*

---

### Test-Execution & Location Audit

*   **Changed surface class:** PR body / contract-comment only.
*   **Location check:** N/A.
*   **Related verification run:** No local tests required for the metadata-only delta. Prior Cycle-1 targeted unit evidence remains valid because head SHA is unchanged; CI was re-checked.
*   **Findings:** Pass for delta scope.

---

### Contract Completeness Audit

*   **Findings:** Pass. The previous mismatch is resolved: the public contract now matches the shipped implementation's #10011 `properties.userId` ownership model.

---

### 🛡️ CI / Security Checks Audit

- [x] Ran `gh pr checks 11704` to empirically verify CI status.
- [x] Confirmed no checks are pending/in-progress.
- [x] Confirmed no checks are failing.

**Findings:** Pass - all checks green: Analyze, CodeQL, retired-primitives check, `integration-unified`, `lint-pr-body`, `lint-pr-review-body`, and `unit`.

---

### Metrics Delta

*   **`[ARCH_ALIGNMENT]`**: 86 -> 92 - Increased because the public contract now explicitly names the same `properties.userId` ownership primitive used by #10011 RLS; remaining deduction only reflects the cross-subsystem KB -> graph dependency complexity noted in Cycle 1.
*   **`[CONTENT_COMPLETENESS]`**: 84 -> 94 - Increased because the Contract Ledger and PR body now match the shipped substrate; small deduction remains because the original ledger over-specification required a correction comment rather than an edited single canonical row.
*   **`[EXECUTION_QUALITY]`**: unchanged from prior review at 90 - Head SHA unchanged, targeted Cycle-1 unit evidence remains valid, and `gh pr checks 11704` is green.
*   **`[PRODUCTIVITY]`**: 88 -> 92 - Increased because the only blocking Required Action is resolved without scope expansion.
*   **`[IMPACT]`**: unchanged from prior review at 88 - The substantive impact remains durable tenant-config storage for Phase 2E.
*   **`[COMPLEXITY]`**: unchanged from prior review at 82 - The code complexity did not change; the delta only clarified contract prose.
*   **`[EFFORT_PROFILE]`**: unchanged from prior review at Architectural Pillar - This remains a tenant-config storage substrate for the KB ingestion epic.
