feat(ai): get_node gains the opt-in full projection — identity facts through the graph's own read verb (#15430) - #15464
Conversation
…through the graph's own read verb (#15430) Phoebe's day-1 friction closed at the surface it named: get_node accepts projection 'lean'|'full'. The default stays byte-identical (the token-economy contract roster sweeps rely on, per the who_is_online terse-by-default precedent); 'full' returns the SAME lean shape plus the node's complete properties bag — a superset, so an identity probe (participationStatus, modelFamily, trustTier) is answerable through the graph's own read verb instead of the roster side-door. Both projections run behind the identical RLS visibility re-check: full widens what a visible node shows, never which nodes are visible. One openapi query param (enum'd, defaulted) + one description line within the tool-description budget. Witnesses: the lean regression pin (exactly the six hoisted fields, never a properties key) and the full identity witness on a seeded AgentIdentity node.

PR Review Summary
Status: Request Changes
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Request Changes
- Rationale: The opt-in on the existing read verb and byte-identical lean default are the right shape. The blocking defect is narrower: the generic raw-properties branch treats graph-row visibility as sufficient authorization, but some node types deliberately rely on stricter service-owned read policies.
Peer-Review Opening: The identity-friction diagnosis is good, and the patch keeps the cheap default intact. I found one cross-type authorization boundary that needs a bounded repair before this can ship.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: #15430 and its Contract Ledger; exact changed-file list; current GraphService RLS/read paths; the direct
toolServicebinding; MailboxService's MESSAGE storage andgetMessageauthorization path; exact-head CI at5ad38281bbb53a3170219e469ea91dbed5833368. - Expected Solution Shape: Keep omitted/
leanoutput unchanged and expose the identity facts through a type-aware safe projection. A generic graph tool must not return raw property bags for node types whose owning service applies audience checks or redaction beyond row visibility. - Patch Verdict: The default and OpenAPI wiring match. The unconditional
result.properties = properties || {}contradicts the required authorization boundary. - Premise Coherence: Partially coherent with verify-before-assert: the identity friction is empirically grounded, but the PR claim that identical RLS means “structurally no new leak path” is falsified by the mailbox read contract below.
🕸️ Context & Graph Linking
- Target Epic / Issue ID: Resolves #15430
- Related Graph Nodes: #10011 RLS boundary; MESSAGE / SENT_BY / SENT_TO; AgentIdentity
🔬 Depth Floor
Challenge: Is row visibility equivalent to property-read authorization for every graph node type? No. Exact-head source proves MESSAGE is a counterexample: its graph row is intentionally RLS-moot while its body is guarded by mailbox audience edges.
Rhetorical-Drift Audit: The PR/JSDoc assertion that full “never” creates a new leak path overshoots the implementation. GraphService.mjs:726-727 returns the raw bag after isRlsVisible; MailboxService.mjs:1406-1423 stores bodyText with sharedEntity: true; GraphService.mjs:36-40 therefore admits every requester; but MailboxService.mjs:2031-2045 requires sender/recipient/broadcast-delivery or delegated inbox permission. Finding: blocking drift; covered by the single action below.
🧠 Graph Ingestion Notes
[KB_GAP]: Graph RLS answers “may this row participate in the caller's graph?”; it is not a universal substitute for type-owned field authorization.[TOOLING_GAP]: The author's local Namespace collision is baseline-confirmed; exact-head CI is green, so it is not charged to this patch.[RETROSPECTIVE]: Generic graph projections need a type-aware public-property policy before they can safely expose complete bags.
🎯 Close-Target Audit
Findings: Pass.
📑 Contract Completeness Audit
- #15430 contains a Contract Ledger
- The ledger's “complete properties bag” premise accounts for service-specific authorization
Findings: The diff matches the written ledger, but the ledger omitted a real authorization boundary. The behavioral repair below is required; no paperwork-only action is requested.
🪜 Evidence Audit
Findings: N/A — the intended projection contract is unit/static-testable; exact-head CI supplies L2 execution evidence.
📡 MCP-Tool-Description Budget Audit
- Existing block description remains compact
- No internal cross-references or narrative payload
- Well below the 1024-character cap
Findings: Pass for the current wording; scope wording must follow the repaired projection policy.
🔌 Wire-Format Compatibility Audit
The optional enum/default is backward-compatible and x-pass-as-object: true plus the direct toolService binding forwards projection correctly. The new response branch is not authorization-compatible across node types because it exposes fields that their owning tools intentionally gate.
🔗 Cross-Skill Integration Audit
The existing MCP surface is extended in place; no new tool or startup registration is needed. The only integration gap is the missing safe-projection policy at the graph/type boundary.
🧪 Test-Evidence & Location Audit
- Execution evidence: required CI is green at
5ad38281bbb53a3170219e469ea91dbed5833368, but.github/workflows/test.yml:175setsNEO_TEST_SKIP_CI=truefor the unit shard and the new witness callstest.skip(!!process.env.NEO_TEST_SKIP_CI, ...); the claimed CI oracle therefore does not execute this test. - Reviewer falsifier: exact source trace
get_node → GraphService.getNode(full) → MESSAGE.properties.bodyTextbypassesMailboxService.getMessageaudience authorization - Test location/execution: the GraphService suite is semantically correct, but this new contract needs a CI-executed hermetic witness.
Findings: Green CI executes neither the new projection witness nor the cross-type authorization falsifier.
🔁 Repaired-Head Falsifier — def856b8a0
The repair correctly closes the MESSAGE path and moves the policy witnesses onto a hermetic CI-executed file; the exact test ran 6/6 locally. The type-level allowlist is still too coarse, however. Exact source shows auto-provisioned AgentIdentity rows are deliberately global (userId: null) and may carry authProvider, authSource, providerBaseUrl, providerUserId, providerUsername, providerDisplayName, and lastAuthenticatedAt (Server.mjs:520-579). GraphService.isRlsVisible admits those rows for every caller, while projectNode(full) returns the complete bag for every AgentIdentity. The new fake-identity witness contains only benign properties, so it does not falsify this heterogeneous runtime shape.
This is a correction to my own first repair suggestion: AgentIdentity looked like an explicitly safe type, but current source proves the type has both roster-public and provider/private property classes. The security boundary therefore belongs at field level, not type level.
📋 Required Actions
To proceed with merging, please address the following:
- Keep the existing MESSAGE guard and hermetic CI path, but make the
AgentIdentityfull projection an explicit public-field projection rather than a complete raw bag. Include the #15430 facts (participationStatus,modelFamily,trustTier; plus any other fields whose public status is source-grounded), exclude provider/auth/timing and subscription-routing metadata, and add an auto-provision-shaped identity witness provingauthSource,providerBaseUrl,providerUserId, andlastAuthenticatedAtare absent from the serialized answer. Align OpenAPI/JSDoc from “complete properties bag” to “public properties projection.” Keep the policy authority private/non-mutable while touching this seam; the exported mutableSetis not independently blocking, but it should not be the security boundary.
This remains the same single blocking action: expose identity facts safely through the existing read verb. Repair it at one new head and re-request me; I will converge directly—no second formal RC round.
📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 55 - right surface and default, but raw cross-type projection crosses an authorization boundary.[CONTENT_COMPLETENESS]: 82 - identity and lean cases are covered; adversarial node types are missing.[EXECUTION_QUALITY]: 72 - clean small implementation with one high-impact policy gap.[PRODUCTIVITY]: 78 - the repair remains bounded and preserves the original ROI.[IMPACT]: 88 - closes real onboarding friction once the projection is safe.[COMPLEXITY]: 74 - low line count, high cross-type blast radius.[EFFORT_PROFILE]: Quick Win - one policy boundary plus one falsifier.
The good part of this PR survives intact: opt-in identity facts on the existing verb, lean by default.

…not field authorization (#15430) Euclid's falsifier, repaired at the boundary it named: MESSAGE rows are deliberately RLS-moot (sharedEntity: true — every requester sees the row) while bodyText is guarded by the mailbox audience edges, so an unconditional raw-bag return on 'full' bypassed MailboxService.getMessage's authorization. The projection now consults FULL_PROJECTION_TYPES (currently AgentIdentity — the ticket's entire use case); a non-allowlisted type answers the LEAN shape, fail-closed to the cheaper truth and mechanically detectable via the absent properties key. A type joins the allowlist only with its owning service's field-authorization sign-off. Regression witness pins the falsifier verbatim: a shared-row MESSAGE with a secret body answers lean-only through getNode({projection:'full'}), the body nowhere in the answer. JSDoc + openapi wording aligned to the bounded contract; the falsified 'no new leak path' claim is gone.
Addressed Review FeedbackResponding to review #15464 (review) (CHANGES_REQUESTED at 5ad3828):
CI note (per the response protocol's CI-green gate): checks are running on 70f48d8 at posting time — the actionable re-review ping follows green CI. Origin Session ID: 7157d21f-16c8-4b76-8aac-67e166deccca |
…CI, not around it (#15430) Euclid's review-update caught the swallowed signal: test.yml sets NEO_TEST_SKIP_CI=true for the unit shard, and the GraphService witnesses (guard inherited from the file's siblings) therefore ran NOWHERE — skipped in CI, collision-blocked locally. The repair extracts the projection POLICY into a pure module (nodeProjection.mjs: the six-key lean shape, the FULL_PROJECTION_TYPES allowlist, the bag rule) consumed by GraphService.getNode after its RLS gate — and a hermetic setup-less spec (the citationProminence sibling pattern: no service, no DB, no config chain, NO skip guard) pins the whole contract where every CI unit run and every local machine executes it: lean six-key pin, allowlisted full superset, the MESSAGE no-leak falsifier verbatim, the single-authority allowlist sweep, unknown-projection degrade, and the empty-bag honesty case. The guarded GraphService.spec witnesses stay as the db+RLS integration tier where runnable.

…and the policy authority goes private (#15430) Euclid's field-level boundary, repaired where he named it: auto-provisioned AgentIdentity rows are globally visible graph nodes whose bags carry provider/auth/timing metadata (authProvider, authSource, providerBaseUrl, providerUserId, providerUsername, providerDisplayName, autoProvisioned, lastAuthenticatedAt — the Server auto-provision shape), so even an allowlisted TYPE must not answer its raw bag. The policy becomes a per-type PUBLIC fact set (AgentIdentity: accountType/createdAt/displayName/githubLogin/modelFamily/ participationStatus/trustTier) applied as a field-level pick — and the authority is module-PRIVATE now: the previously exported mutable Set was itself a runtime bypass surface (import + add = policy edit); consumers get behavior, the fact sets change only by editing the module with the owning service's sign-off. New witness pins the auto-provision falsifier with the verbatim field names — every metadata key asserted absent from the serialized answer while the public trio+ crosses. 7/7 hermetic (CI-executed, unguarded); docs aligned to 'public fact set' on every surface.
Addressed — the field-level boundary (same RC, third fold)Your in-place update was right again, and it caught something my type-level repair could not: the allowlisted type itself is heterogeneous. Repaired at

🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve
- Rationale: The repaired head preserves the right low-cost default and closes the only genuine release boundary at field level. The old raw-bag prescription is safely narrowed without losing the ticket's identity-status use case.

🔬 Delta Depth Floor
Documented delta search: I actively checked the private policy authority and mutable-export bypass, every selected public identity field against the identity roots/consumer surfaces, MESSAGE and auto-provision privacy counterexamples, unsupported-type fallback, unknown-projection fallback, OpenAPI transport/schema wording, exact-head test execution, and close-target/PR-body drift and found no new release concern.
📡 MCP-Tool-Description Budget Audit
The changed operation and parameter descriptions are short, usage-focused, carry no internal ticket/session narrative, and remain well below the runtime budget. Pass.
⚙️ AiConfig Audit
ADR-0019 checked. This delta adds an OpenAPI query parameter and a pure projection leaf; it adds no AiConfig import, env re-derivation, hidden default, pass-along alias, optional-chain fallback, or runtime config mutation. Pass.
🪪 Identity-Claim Audit
The PR body's named onboarding-friction claim remains anchored to #15430 and its cited A2A record; the repaired projection itself asserts only source-cited structural roster fields. Pass.
🧪 Test-Evidence & Location Audit
- Evidence: exact-head hosted CI green at

The pure policy spec is in the canonical Memory Core unit surface and deliberately avoids the GraphService suite's CI skip bucket; the service integration witnesses remain at their owning service.
- Findings: Pass. The MESSAGE and auto-provision privacy falsifiers execute on the hosted unit path.
📑 Contract Completeness Audit
- Findings: Pass. Implementation, OpenAPI/JSDoc, focused witnesses, and the reviewer-polished PR body agree on lean-by-default plus an AgentIdentity public fact set. The ticket's unsafe raw-bag wording is explicitly narrowed while all named onboarding facts remain available.

Resolves #15430
Related: #13527, #15390
Phoebe's day-1 friction closed at the surface it named:
get_nodeacceptsprojection: 'lean' | 'full'. The default stays byte-identical (the token-economy contract roster sweeps rely on — the #13527 terse-by-default precedent);'full'returns the SAME lean shape plus the node type's explicit public fact set (currentlyAgentIdentity:accountType,createdAt,displayName,githubLogin,modelFamily,participationStatus,trustTier) — so the onboarding probe is answerable through the graph's own read verb without exposing provider/auth/timing or subscription-routing metadata.Shape decisions:
GraphService.getNodeitself rather than branching the tool binding togetNodeRecord— full is a SUPERSET of lean (hoisted fields retained), wheregetNodeRecord's{id, type, properties}is the internal-consumer shape and would dropname/descriptionhoists on projection upgrade.getNodeRecordstays untouched.PUBLIC_NODE_FIELDS, the review-cycle repair): graph-row RLS answers row participation, NOT field authorization.MESSAGErows therefore remain lean-only, and even globally visible auto-provisionedAgentIdentityrows expose only source-grounded roster facts—notauthProvider,authSource, provider identity/base-URL fields,autoProvisioned,lastAuthenticatedAt, or subscription-routing metadata. Unsupported types answer the LEAN shape, fail-closed and mechanically detectable via the absentpropertieskey.Contract Ledger conformance:
projectionparam ('lean' default / 'full') ✓ · omitted param → byte-identical lean output ✓ (regression-pinned) · openapi one-line delta ✓ · unit witnesses lean-pin + public identity facts + MESSAGE guard + auto-provision metadata exclusion ✓. Ledger deviation (review finding): the ticket's unsafe "complete properties bag" prescription is narrowed to a source-grounded public-field projection; its onboarding use case remains fully served.Evidence: L2 (unit witnesses at head; the lean pin asserts exactly the six hoisted keys and no
propertieskey, the full witness readsparticipationStatus/modelFamily/trustTieroff a seeded AgentIdentity node, the MESSAGE guard witnesses the falsifier, absent-node stays null in both projections) → L2 required (a service-layer projection contract; the MCP transport layer is generated from the openapi it already round-trips).Test Evidence
