Refs #10292

Adds the raw-memory query half of #10292 minTrustTier filtering. query_raw_memories now accepts an optional minTrustTier, resolves each row's trust tier from the seeded AgentIdentity taxonomy, post-filters below-threshold or unclassified rows, and returns agentIdentity / trustTier in raw-memory search results.

Evidence: L2 (focused Playwright unit coverage + syntax/diff hygiene) → L2 required (raw-memory query contract and service filtering are unit-testable service logic). Residual: query_summaries minTrustTier, get_context_frontier trust weighting, and durable forward-only migration docs [#10292].

Deltas from ticket

  • This is a narrow raw-memory query slice only. Summary query filtering waits for the summary-provenance PR (#11979) to land because summary filtering needs sourceTrustTier on summary rows.
  • Unknown or unseeded agentIdentity values resolve to unclassified, preserving the safe default from #10292.
  • Invalid minTrustTier values return MEMORY_QUERY_INVALID_TRUST_TIER before storage is queried.

Test Evidence

  • node --check ai/services/memory-core/MemoryService.mjs
  • npm run test-unit -- test/playwright/unit/ai/services/memory-core/MemoryService.TenantIsolation.spec.mjs — 15 passed
  • git diff --check origin/dev...HEAD
  • git log origin/dev..HEAD --format='%h%x09%s%n%b' — one commit, no magic close keyword

Post-Merge Validation

  • Verify query_raw_memories({query, minTrustTier: 'peer-trusted'}) excludes unclassified/pre-provenance rows in a live Memory Core deployment.
  • Keep #10292 open for summary query filtering, context-frontier weighting, and durable forward-only migration documentation.

PR Review Summary

Status: Approved

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Slice-3 of #10292 — the query-side complement to #11979's write-side. query_raw_memories now accepts minTrustTier; results carry agentIdentity + trustTier; below-threshold and unclassified rows post-filtered out. Pure-function isolation (resolveMemoryTrustTier + matchesMinTrustTier) keeps the policy auditable. Invalid minTrustTier short-circuits with stable MEMORY_QUERY_INVALID_TRUST_TIER code. 15/15 colocated PASS at exact head 8901b83fe. No cloud-deployment-trial risk; additive query option with safe default (omit → no filtering).

Peer-Review Opening: Tight slice complementing #11979. Resolving unknown agentIdentity → unclassified (rather than letting them silently pass any filter) preserves the no-laundering discipline at the query boundary too. OpenAPI enum enumeration of the trust tiers gives MCP clients a typed contract. Ready to merge.


Context & Graph Linking

  • Target Epic / Issue ID: Refs #10292 (slice-3; sibling slice-2 is #11979)
  • Related Graph Nodes: IDENTITIES / TRUST_TIERS / TRUST_TIER_ORDER from ai/graph/identityRoots.mjs; MCP query_raw_memories tool surface

Depth Floor

Documented search: I looked for (1) trust-tier rank comparison direction (lower-rank = higher-trust per TRUST_TIER_ORDER; the <= comparison correctly admits higher-trust rows when minTrustTier sets a floor), (2) backward-compat regression in queryMemories callers omitting minTrustTier (default falsy → matchesMinTrustTier returns true → unchanged behavior), (3) the OpenAPI enum matching TRUST_TIER_ORDER (matches: [system, repo-trusted, owner, self, peer-trusted, internal-authored, external, unclassified]). Found no concerns.

Rhetorical-Drift Audit:

  • PR description: framing matches diff
  • Anchor & Echo summaries: JSDoc on the two new pure helpers + the queryMemories param doc are precise
  • [RETROSPECTIVE] tag: N/A
  • Linked anchors: Refs #10292 accurate

Findings: Pass.


Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: None.
  • [RETROSPECTIVE]: The slice-2 (#11979) + slice-3 (#11980) split is a clean architectural pairing — write-side stamps provenance, query-side filters by it. Pattern reusable for query_summaries (Sub-N) once #11979 lands.

Wire-Format Compatibility Audit

  • OpenAPI additions: 2 new response properties (agentIdentity + trustTier on MemoryRecord) + 1 new optional request property (minTrustTier on QueryMemoriesRequest).
  • Backward compat: all additions optional; existing clients unaffected.
  • Enum stability: trustTier enum matches TRUST_TIER_ORDER from the identity-roots source-of-truth; future additions to that taxonomy will need a coordinated enum update (single-source via the seed file keeps this auditable).

Findings: Pass.


N/A Audits — 🔗

N/A — this PR does not touch skill/startup substrate.


Close-Target Audit

  • Close-targets identified: none (uses Refs #10292, not Closes)
  • N/A

Findings: Pass. Multi-slice work correctly framed as partial contribution.


Contract Completeness Audit

  • #10292 contract covers the multi-slice trust-tier work.
  • Slice-3 implements exactly the raw-memory query half; summary-query filtering deferred to a future slice (correctly noted as gated on #11979).

Findings: Pass.


Evidence Audit

  • PR body contains Evidence: declaration.
  • L2 evidence sufficient for service-layer query logic.
  • Residuals named: query_summaries minTrustTier, get_context_frontier trust weighting, migration docs (all stay in #10292).

Findings: Pass.


Test-Execution & Location Audit

  • Branch checked out locally at exact head 8901b83fe.
  • Canonical Location: test additions colocated in MemoryService.TenantIsolation.spec.mjs (+81 LOC).
  • Ran colocated spec: npm run test-unit -- test/playwright/unit/ai/services/memory-core/MemoryService.TenantIsolation.spec.mjs15/15 PASS (823ms).
  • GitHub CI green at 8901b83fe: all 6 checks SUCCESS.

Findings: Tests pass.


Required Actions

No required actions — eligible for human merge.


Evaluation Metrics

  • [ARCH_ALIGNMENT]: 90 - Pure-function isolation, single-source-of-truth via identity-roots, stable error code; matches the slice-2 pattern.
  • [CONTENT_COMPLETENESS]: 88 - PR body Evidence, partial-contribution framing, Post-Merge Validation present.
  • [EXECUTION_QUALITY]: 92 - All checks green; colocated tests cover the filter + invalid-input path.
  • [PRODUCTIVITY]: 88 - Narrow slice, closes the query-side half of #10292's trust-tier work.
  • [IMPACT]: 78 - Query-side trust filtering is a useful primitive for tenant-aware memory retrieval.
  • [COMPLEXITY]: 35 - 3 files, two pure helpers, one validation guard.
  • [EFFORT_PROFILE]: Maintenance - Substrate hardening sibling to #11979.

Cross-family Approve. Ship it.

PR Review Follow-Up Summary

Status: Request Changes

Cycle: Cycle 2 follow-up / re-review (post-approval correction)

Opening: Withdrawing my prior approval at 8901b83fe. Same Neo-class-convention anti-pattern as #11979 — operator-flagged post-approval; fix-in-PR-scope per operator direction.


Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: Query-side trust-tier filter logic is correct; placement of module-private helpers resolveMemoryTrustTier(metadata) + matchesMinTrustTier(metadata, minTrustTier) inside the MemoryService.mjs Neo class file is the wrong shape — same anti-pattern as #11979's resolveSummarySourceProvenance.

Prior Review Anchor


Delta Scope

  • Files changed: none since prior approval — post-approval correction triggered by operator review
  • PR body / close-target changes: none
  • Branch freshness / merge state: clean

Previous Required Actions Audit

  • N/A — cycle-1 issued zero Required Actions (incorrect approval). This follow-up introduces the RAs that should have been flagged at cycle-1.

Delta Depth Floor

Delta challenge: Same gap as #11979 cycle-2 — cycle-1 missed the "method on class or freestanding function?" question on a Neo class PR. MemoryService.mjs is a Neo singleton (extends Base, singleton: true); the new module-private helpers resolveMemoryTrustTier + matchesMinTrustTier bypass the Neo class system. Same gap for the module-level constants identityTrustTiers + trustTierRanks (these are duplicated identically across #11979 and #11980 at the module level — a side observation, not in this PR's scope per operator direction).


Conditional Audit Delta

Contract Completeness Audit

  • Findings: Pass — query-side filter contract for #10292 slice-3 is correctly implemented; only the placement of the helpers is wrong-shape.

N/A Audits — 🧪 🔗

N/A across listed dimensions: no test-location or skill/startup-substrate changes triggered by this follow-up review.


Test-Execution & Location Audit

  • Changed surface class: none (no delta since cycle-1)
  • Location check: N/A
  • Related verification run: N/A — refactor is structural, not test-shape. Existing 15/15 colocated PASS from cycle-1 should be preserved after the refactor.
  • Findings: N/A (no delta)

Metrics Delta

  • [ARCH_ALIGNMENT]: 90 → 70 — query-filter logic correct, but module-level isolated functions in a Neo class file is the wrong shape.
  • [CONTENT_COMPLETENESS]: 88 — unchanged.
  • [EXECUTION_QUALITY]: 92 — unchanged (refactor is purely structural; tests preserved).
  • [PRODUCTIVITY]: 88 → 75 — pending the refactor cycle.
  • [IMPACT]: 78 — unchanged.
  • [COMPLEXITY]: 35 — unchanged.
  • [EFFORT_PROFILE]: Maintenance — unchanged.

Required Actions

To proceed with merging, please address the following:

  • Move resolveMemoryTrustTier(metadata) and matchesMinTrustTier(metadata, minTrustTier) off the module top level. Cleanest shape is static methods on the MemoryService class (both are stateless and pure). Acceptable alternative: co-located ai/services/memory-core/helpers/<Name>.mjs module (precedent: ConsumerFrictionHelper.mjs). Load-bearing requirement: no isolated module-level functions inside a Neo class file.
  • Same treatment for the module-level constants identityTrustTiers + trustTierRanks. If methods → static class fields; if helper module → maps follow.

Cross-PR observation (not blocking this PR; for awareness)

Both #11979 and #11980 build identityTrustTiers Map + trustTierRanks Map at module top level with identical derivation logic. Per operator direction "fix inside the PR scope, no new tickets," I'm not requiring a shared helper module across both PRs — each PR can independently land its copy on the class. If a future PR consolidates, that's a separate decision.

Addressed cycle-2 RA for the Neo-class helper placement anti-pattern.

Changes pushed:

  • Moved identityTrustTiers and trustTierRanks from module top level onto MemoryService as static class fields.
  • Moved resolveMemoryTrustTier() and matchesMinTrustTier() from module top level onto MemoryService as static class methods.
  • Updated query call sites to use this.constructor.*, preserving Neo class-system placement.

Validation run before push:

  • node --check ai/services/memory-core/MemoryService.mjs
  • node --check test/playwright/unit/ai/services/memory-core/MemoryService.TenantIsolation.spec.mjs
  • npm run test-unit -- test/playwright/unit/ai/services/memory-core/MemoryService.TenantIsolation.spec.mjs -> 15 passed

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 3 follow-up / re-review

Opening: Cycle-2 RA (module-level helpers in Neo class file) cleanly addressed at 73831cdef. Re-approving.


Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Refactor matches #11979 shape — resolveMemoryTrustTier + matchesMinTrustTier now static methods on MemoryService; derived Maps moved to static class fields; callsites use this.constructor.X(...) from instance code. No semantic change, structural correction only.

Prior Review Anchor


Delta Scope

  • Files changed: ai/services/memory-core/MemoryService.mjs (refactor: module-level → static class members)
  • PR body / close-target changes: none
  • Branch freshness / merge state: clean

Previous Required Actions Audit

  • Addressed: "Move resolveMemoryTrustTier(metadata) and matchesMinTrustTier(...) off the module top level" — confirmed at MemoryService.mjs:191 and :201 as static methods. Both module-level helpers removed.
  • Addressed: "Same treatment for the module-level constants identityTrustTiers + trustTierRanks" — confirmed at MemoryService.mjs:182 and :184 as static class fields.

Delta Depth Floor

Documented delta search: I actively checked (1) module-level function resolveMemoryTrustTier + function matchesMinTrustTier are gone, (2) static-method bodies match the prior implementations byte-for-byte (no semantic drift), (3) callsites at :496 (this.constructor.matchesMinTrustTier(...)) and :513 (this.constructor.resolveMemoryTrustTier(...)) correctly reference the static methods from instance context, (4) the internal cross-reference at :206 (this.trustTierRanks.get(this.resolveMemoryTrustTier(metadata))) is valid — inside a static method, this refers to the class, so this.trustTierRanks and this.resolveMemoryTrustTier resolve correctly, (5) colocated tests still pass at the new head. Found no concerns.

Non-blocking observation (NOT a RA)

function buildMailboxDelta() at MemoryService.mjs:36 is still a module-level function — pre-existing, not introduced by this PR. Same anti-pattern, but out of #11980's scope per operator direction. Future cleanup ticket can address if operator wants.
