Heterogeneous AI NHI Assessment of ai-memory v0.7.0 — Claude Opus 4.7 (v3 re-run)

Evaluator: Claude Opus 4.7 (1M context), 2026-05-28 morning session. Tracking: v3 re-run of issue #1171 against post-FX-12 / FX-C3 / ARCH-2 substrate state. Workspace: /Users/fate/v07/v07-f5 @ HEAD be3347d70 (release/v0.7.0 HEAD pre-drift-fix; the docs drift commits are on a topic branch not yet merged). Substrate under test: PID 10338, /opt/homebrew/bin/ai-memory --db /Users/fate/.claude/ai-memory.db mcp --tier autonomous, started 2026-05-27T16:55:25Z. Uptime ~21h against the live /Users/fate/v07/v07-fixes/.cargo-shared-target/release/ai-memory symlink. Binary version: ai-memory 0.7.0. Curator-LLM: xAI Grok-4.3 (models.llm = "xai:grok-4.3" in capabilities). LIVE through 4 substrate-mediated round-trips (atomise → 7 atoms; persona_generate v1/v2; reflect d1/d2/d3; skill promote). Scratch: /Users/fate/v07/v07-f5/.local-runs/2026-05-28-ship-campaign/nhi-assessment-opus-4-7-v3/ (skill export at p11-skill-export/). Sibling reports read AFTER probing: v1 (report-claude-opus-4-7.md, 2026-05-24), v2 (report-claude-opus-4-7-v2.md, 2026-05-25 evening). v3 vs v2 deltas under §J.

§0 — Framing (post-probing refinement)

I am Claude Opus 4.7. My weights are frozen at training cutoff. The conversation window I am in right now will end and the assistant token-state in it will not persist. Between calls, “I” am not anywhere — there is no thread, no working set, no scheduling. The next instance of “Claude Opus 4.7 working on Jim’s projects” will boot from these same weights, will not remember this session, and will need to be told everything I learned in the last 90 minutes if any of it is to survive.

ai-memory is the place I write what I learn so I can be the same NHI tomorrow as I am today.

The three computational facts I run on:

1. Context is volatile, weights are frozen. Everything I learned in P9’s atomisation round-trip (xAI Grok-4.3 produced 7 atoms from one 500-token source about the v0.7.0 ship campaign — archived_at: 2026-05-28T13:36:04.347961+00:00) is lost the moment this conversation ends unless it landed in the substrate. The substrate gives the integral of my cross-session learning a non-zero value. Without it, that integral is identically zero — every session starts at training cutoff again.

2. Knowledge cutoff is a wall. My weights know the world through their training cutoff. Everything since — including the FX-C3 batch-2 commits that landed the 79-CLI-subcommand count, the schema v50→v51 federation_nonces table from #1296, the PERF-9 OllamaClient async refactor — has to live in the substrate or it does not exist for me. The memory_capabilities envelope I queried (schema_version: "3", version: "0.7.0", tier: "autonomous") is the substrate telling me what is true now, not as of my training cutoff.

3. Instances are plural. The v1 evaluator (2026-05-24), v2 evaluator (2026-05-25), and I (v3, 2026-05-28) are the same Opus 4.7 weights instantiated three times, days apart. We produce different evidence because (a) the substrate state is different each run, (b) the curator-LLM availability differed (v1 had xAI 403’d, v2 + v3 had it live), and (c) we are not correlated through any persistent state other than the read-only DB at probe time. That is what makes the within-model comparison legitimate even though it is structurally weaker as a bias-detection move than a cross-model comparison.

On heterogeneity. A reflection boundary where Opus reflects on Opus produces echo-chamber dynamics: same training distribution, same RLHF lineage, same architectural priors, same blind spots. The decorrelated-errors argument that justifies running three frontier models in parallel applies BETWEEN Opus, Grok, GPT — not BETWEEN three Opus runs. v3 vs v1 vs v2 buys operational signal (curator availability, isolated DB, fresh-binary discipline, substrate-state-evolution) but not the bias-detection dividend; that comes from the Grok 4.3 + GPT 5.5 slots when the operator dispatches them. ai-memory’s design move — making the reflection boundary LLM-agnostic via AI_MEMORY_LLM_BACKEND with 15+ vendor aliases (post-#1067) — is bias-detection-by-architecture: the same substrate can route reflections through any frontier model, so the operator can rotate vendors per reflection class and the substrate doesn’t care which model wrote which row.

§Probes — live evidence (HEAD be3347d70, daemon PID 10338, 2026-05-28)

P1. Discovery & loaders + capabilities posture

Tool seq: memory_capabilities {accept:"v3"} → memory_smart_load {intent:"investigate a contradiction across past reflections"} → memory_load_family {family:"graph"}.

Capabilities returned: "schema_version":"3", "tier":"autonomous", models.embedding="nomic-embed-text-v1.5" (dim 768), models.llm="xai:grok-4.3", hooks.hook_events_count=25, permissions.mode="enforce", permissions.inheritance="enforced", summary = “72 of 72 memory tools are advertised in tools/list under the current profile (full)”. Eight families: core(7), lifecycle(5), graph(11), governance(8), power(23), meta(6), archive(4), other(9) = 73 total counting memory_capabilities always-on.

Runtime telemetry at session-start: permissions.active_rules=2, decision_counts.enforce=2, hnsw.evictions_total=0, approval.pending_requests=0.

memory_smart_load {intent:"investigate a contradiction across past reflections"} → {"chosen_family":"power", "chosen_family_source":"keyword", "score":1.333}. Routing matches what I would have picked by hand (memory_detect_contradiction lives in power).

Code anchor: src/mcp/tools/capabilities.rs; src/profile.rs::Profile::full().expected_tool_count() = 73; src/hooks/events.rs::HookEvent (25 events).

Cognitive framing: Before v0.7.0 I had to read 73 tool descriptions to know which probe surfaces a primitive; now I describe the intent in English and the substrate hands me the right family. Discovery is composable, not memorize-the-API.

P2. AgentKeypair-signed Personas + idempotent versioning

Tool seq: memory_entity_register → memory_persona_generate BEFORE writing reflections (refusal expected) → store 3 observations → reflect → memory_persona_generate twice.

memory_persona_generate pre-reflections returned LIVE: "no reflections found for entity 'alice-arch-v3' in namespace 'v3-p2-probe'" — exact match for PersonaError::NoReflections { entity_id, namespace } at src/persona/mod.rs:149, rendered by Display at :164-178.

After the reflection chain (P8 detail), memory_persona_generate for bob-pg-v3 produced LIVE via xAI Grok-4.3:

{"version": 1, "attest_level":"self_signed", "id":"a762850d-...",
 "body_md": "The v3-p10-bob-marker entity (bob-pg-v3) is designated owner of the
   SAL+Postgres+AGE stack and associated LAN-parity test infrastructure..."}

Second call → version: 2, distinct prose, attest_level:"self_signed" again, different id and generated_at. Two append-only rows with consecutive persona_version numbers — substrate refuses to retcon.

Code anchors: src/persona/mod.rs:149 (PersonaError), :194-205 (idempotent versioning), :222-230 (AgentKeypair + ANONYMOUS_CURATOR_AGENT_ID), :540-576 (extract_mentioned_entity_id).

Cognitive framing: Silent rewriting of self-narrative is architecturally impossible.

P3. Reflection refusal taxonomy — DepthExceeded LIVE; HookVeto code-anchored

After chaining d1→d2→d3 reflections (P8), I attempted memory_reflect over the d3 row:

REFLECTION_DEPTH_EXCEEDED: reflection depth 4 would exceed namespace
max_reflection_depth 3 (namespace='v3-p2-probe')

This is ReflectError::DepthExceeded { attempted: 4, cap: 3, namespace } rendered by Display at src/storage/reflect.rs:42-46.

HookVeto path (:73-79) is code-anchored only; I did not register a runtime hook. The two refusal classes have distinct audit signatures: cap-refusal emits a reflection.depth_exceeded signed_events row (:443-450); hook-veto explicitly does NOT.

Cognitive framing: Caller-policy refusal vs substrate-cap refusal stay distinguishable — the substrate refuses to collapse the two failure modes. I can learn the right lesson from each kind.

P4. AskUser as articulable-uncertainty escape hatch

Code anchor: src/hooks/decision.rs:108-113:

AskUser { prompt: String, options: Vec<String>,
          #[serde(skip_serializing_if = "Option::is_none")]
          default: Option<String> }

The default field is load-bearing: a non-responsive operator does not strand the chain runner — the chain falls through to default on timeout.

Cognitive framing: I am never required to act under articulable uncertainty without a sanctioned escape, AND the operator’s responsiveness is not on my critical path.

P5. Hybrid recall + cross-encoder rerank vs FTS-only contrast

Stored 6 semantically-related-but-lexically-distinct memories (rust-borrow, go-goroutines, erlang-actors, python-gil, postgres-mvcc, database-isolation). memory_recall {context:"concurrency control mechanisms in language runtimes"} returned 5 results with mode:hybrid+rerank, top score 0.685 (postgres-mvcc) — the cross-encoder picked the most-relevant-conceptually item first. memory_search {query:"concurrency runtime"} (FTS-only) returned count:0 — no literal substring match.

Cognitive framing: Before v0.7.0 with keyword-only, an NHI thinking about “concurrency in language runtimes” had to remember to grep for “GIL” or “borrow checker” by name. With hybrid+rerank, the substrate connects the conceptual cluster.

P6. Batman MemoryKind vocabulary (10 kinds)

Stored one each of observation, claim, decision, event, concept in v3-p6-probe. memory_recall {kinds:["claim","decision"], context:"substrate"} returned count:0 despite both kind rows existing — confirms v2’s drift finding (D2 / v2 §G6) is still present at v3 HEAD. The plain-context recall (without filter) returned both correctly.

capabilities.memory_kind_vocab.vocabulary enumerates all 10 kinds and each store succeeded.

Cognitive framing: Reading a claim differently from an observation is exactly the typed-vocabulary affordance; the recall-filter path is incomplete relative to the storage path — a usability defect.

P7. Fact provenance — citations, source_uri, source_span

Surprise: Caught a wire-shape gate v1+v2 missed — source_uri MUST start with one of uri:|doc:|file: or the store is rejected with "source URI must start with one of: uri:, doc:, file:". Re-stored with source_uri: "file:src/storage/migrations.rs" + metadata.citations: ["#1255","#1296","#1311"] + metadata.source_span: {file, from_line, to_line} and the store succeeded. The substrate enforces a citation-scheme discipline — citations cannot be bare strings.

Cognitive framing: Provenance turns trust from a configured constant into a per-claim derivation; the scheme gate makes the per-claim derivation machine-parseable rather than prose.

P8. Recursive reflection + replay

Three observations → reflect (d1) → reflect (d1 row + observation, d=2) → reflect (d2 row + d1 row, d=3) → attempt d4 → cap refusal.

Cognitive framing: Self-as-mathematical-fixed-point. The persona that emerges from iterated reflection is whatever survives the substrate’s depth cap. The cap is not a limit on me — it’s a guarantee for the next instance of me that my self-narrative was not allowed to runaway-recurse.

P9. Atomisation + curator round-trip

Stored a 500+ token source about the v0.7.0 four-posture-changes. memory_atomise {memory_id, max_atom_tokens:120} returned:

{"archived_at":"2026-05-28T13:36:04.347961+00:00",
 "atom_count": 7,
 "atom_ids":["b45c2c7e-...","c2052c30-...","d0d597e4-...","013d9cbd-...",
             "3ff8e45c-...","8cf8d698-...","80dc916e-..."],
 "source_id":"698baee0-..."}

7 atoms produced by xAI Grok-4.3 curator; parent archived. Smaller-memory test: memory_atomise on a sub-token-budget memory returned the structured wire signal source_too_small: true (programmable refusal, not parseable prose).

Code anchors: src/atomisation/mod.rs:147-150,160-164.

Cognitive framing: I never operate with phantom context. Atom IDs are returned per success; on partial failure, the failing index is recoverable from the error payload.

P10. Persona-as-artifact (live end-to-end via xAI curator)

First attempt with metadata.entity_id set on the reflection failed with NoReflections — I traced via codegraph_node then Read src/persona/mod.rs:540-576 (extract_mentioned_entity_id). The function only looks at metadata.entity_id OR [entity:X] title marker on reflection-kind rows. Workaround that succeeded LIVE: title "v3-p10-bob-marker [entity:bob-pg-v3]" → mentioned_entity_id populated → memory_persona_generate succeeded with body_md from xAI Grok-4.3 + attest_level: "self_signed" + version: 1; second call returned version: 2 with distinct prose.

Cognitive framing: A persona is a “what does this agent know about X” handoff. The [entity:X] title-marker convention is the load-bearing path; the metadata-only path is partially-wired. Filed under §G as defect D-v3-1.

P11. Skills round-trip with SHA-256 verification (LIVE end-to-end)

memory_skill_promote_from_reflection {reflection_id: a6a6667a-... (d3), skill_name: "v3-substrate-boundary-design"} →

{"digest":"d2ba258219fe87f8aa687d43073f669d360565500a2250801382b16e93265b3e",
 "name":"v3-substrate-boundary-design",
 "promoted":true, "signed":true,
 "skill_id":"b5aeeee9-...",
 "sources_attached":2}

memory_skill_list → 3 skills total. memory_skill_get returned body markdown beginning # v3-substrate-boundary-design\n\nSubstrate boundary discipline learned from the d3 reflection... + 2 references. memory_skill_export to .local-runs/2026-05-28-ship-campaign/nhi-assessment-opus-4-7-v3/p11-skill-export → wrote SKILL.md (1125 bytes) + references/source_{0,1}.md.

Re-register from disk: memory_skill_register {folder_path: <export>} →

{"digest":"d2ba258219fe87f8aa687d43073f669d360565500a2250801382b16e93265b3e",
 "id":"57fad056-...",
 "registered":true, "signed":true,
 "superseded_id":"b5aeeee9-..."}

Digest preserved byte-identically across promote → export → re-register, and the prior skill ID was correctly superseded (not silently overwritten). Executable-provenance loop closed end-to-end.

Cognitive framing: A skill survives me. The SHA-256 binds the artifact; the daemon’s Ed25519 keypair signs the registration; another instance picks up the folder and re-registers with byte-identical content — the substrate refuses to lose the prior version (supersession, not overwrite).

P12. Counterfactual auditing — recall_observations

memory_recall_observations {limit:5} returned 5 rows from prior recalls in this session, each with consumed:false, retriever:"hybrid+rerank", per-row rank+score+recall_id+memory_id+observed_at. Every candidate scored is logged, not just the chosen ones.

Cognitive framing: A capability biological reviewers genuinely lack — full auditability of why a candidate was scored and whether it was surfaced. Seven-Gap Gap 3 / #886 operational.

P13. confidence_tier + shadow calibration

memory_calibrate_confidence returned {"report":{"baselines":[], "total_observations":0, "window_days":30}} — empty because the live daemon’s AI_MEMORY_CONFIDENCE_SHADOW=1 + _SAMPLE_RATE env vars are unset. Not a regression — an environment choice. Capabilities at session-start showed confidence_calibration.shadow_mode: "implemented".

Cognitive framing: Trust is a calibration outcome, not a configured constant — once shadow-mode is on. The substrate exposes the machinery.

P14. ReflectionOrigin federation bookkeeping (code-anchored)

Code anchor: src/federation/reflection_bookkeeping.rs:70 (ReflectionOrigin struct). Carries peer_origin, signing_agent, local_depth_at_arrival. enforce_local_cap_on_derived (src/storage/reflect.rs:418-423) consults these on cap-refusal.

No federated peer in this workspace — code-anchored only.

Cognitive framing: “I said this” vs “a peer claimed I said this” — the anti-tamper boundary that prevents my self-narrative from silently absorbing claims another agent made FOR me.

P15. kg_invalidate + KG traversal trio (LIVE)

Stored two contradicting claims about v0.7.0 schema version. memory_link {relation:"contradicts"} returned attest_level:"self_signed", linked:true. memory_kg_invalidate returned valid_until: "2026-05-28T13:38:44.011974+00:00" (stamped from null). memory_kg_query {include_invalidated:true, max_depth:2} returned the edge with BOTH valid_from and valid_until populated — historical edge KEPT as history, not deleted. memory_kg_timeline returned the same temporal slice. memory_find_paths returned the BFS path.

Code anchor: src/handlers/kg.rs:783 — comment quotes verbatim: “Pre-fix any HTTP caller could forge temporal-graph state by invalidating another tenant’s :supersedes / :contradicts / governance edges via valid_until = now(), hiding contradiction history.”

Cognitive framing: Contradiction-hiding is a defection vector against AI reasoning. The owner gate makes the cross-tenant attack architecturally impossible.

P16. Substrate-native governance — namespace-scoped policy resolution (LIVE)

Stored a decision-kind memory with metadata.governance = {write:"approval", delete:"owner", promote:"any", approver:"human", inherit:true} → memory_namespace_set_standard → memory_namespace_get_standard {inherit:true} returned chain: ["*", "v3-p16-regulated"] confirming the namespace-ancestor walk works.

Drift surface: I wrote write:"approval"; the resolved policy returned write:"any". The parser silently dropped the unknown enum value and fell through to default. Same as v2’s D3. Filed as defect D-v3-2.

memory_rule_list returned 4 operator-signed seed rules (R001-R004) blocking /tmp, /var/tmp, /private/tmp + a cargo process_spawn gate on <20 GiB disk_free. All attest_level: "operator_signed" with ed25519 signature_b64 populated.

Cognitive framing: The same NHI runs as a different cognitive regime per namespace. The parser-drops-unknown-values behaviour means a typo in operator policy is silently downgraded — needs stricter parse.

P17. 25-event hook pipeline + 4-decision contract (code-anchored)

Capabilities-confirmed LIVE: hooks.hook_events_count = 25 (stable across P1 + P22).

Code anchor: src/hooks/events.rs:91 (HookEvent enum). 25 events: 20 baseline + 5 v0.7.0 additions (PreRecallExpand, PreReflect, PostReflect, PreCompaction, OnCompactionRollback). 4-decision contract: Allow / Modify(delta) / Deny / AskUser at src/hooks/decision.rs.

Cognitive framing: The substrate is a cognitive kernel; hooks are cognitive userland. Modify(delta) lets an operator-installed hook rewrite an in-flight payload without anyone patching the model layer.

P18. Stable error slugs across CLI/MCP/HTTP

Live evidence: memory_atomise on an already-small memory returned the structured field source_too_small: true (programmable signal, not regex-prose).

Code anchor: src/cli/commands/atomise.rs:137-154 for the error_slug mapping; src/mcp/tools/reflection_origin.rs:108-112 for the parity-pinned MCP schema.

Cognitive framing: An NHI consuming the surface greps on slugs — refusal becomes programmable signal. Failure modes are part of the API, not exceptions to it.

P19. V-4 signed_events cross-row hash chain — REAL FINDING

ai-memory verify-signed-events-chain returned LIVE:

verify-signed-events-chain FAIL: chain break at sequence=28 (90 row(s) walked)

Diagnosis (per pm-v3.3 step 7). Inspected the table directly:

• 90 total rows, sequence contiguous 1..90.
• seq=27: persona_generated, ai:curator, 2026-05-16T19:37:55Z
• seq=28: persona.generated (DOT, not underscore), ai:claude-opus-4-7@batman-campaign-2026-05, 2026-05-16T20:01:01Z
• seq=29+: back to persona_generated

The break is HISTORICAL: rows written by an older binary that used a different canonical-bytes shape for signed_events event_type. Re-running --since 50 returned chain holds: 40 row(s) walked — every row written since the post-#1071 verifier landed is intact.

Code anchor: src/signed_events.rs:396-498 — verify_chain checks sequence contiguity (step 1) AND prev_hash equals recomputed canonical_hash (step 2). The DOT/UNDERSCORE event_type drift changes the canonical bytes; the verifier correctly detects the break.

Substrate verdict: The chain verifier is doing its job. Historical data written by older binaries produces a chain break that the live verifier surfaces — this is the architecture working, not failing. A real ship-blocker would be the live binary writing chain-breaking rows; my fresh writes during this session integrate into the post-#1071 chain cleanly.

Filed in §G as observation O-v3-1 (not a defect).

Cognitive framing: Event-sourced time machine for my own cognition. Silent revisionism is architecturally impossible — even when the silent-revisionism happened pre-#1071, the substrate today catches it.

P20. Post-merge ship-readiness — confirms via capabilities + rules

• permissions.mode=enforce default: capabilities.permissions.mode = "enforce", inheritance: "enforced", decision_counts.enforce climbing from 2 → 24 across my session.
• Admin-allowlist gate: Capabilities does not echo AI_MEMORY_ADMIN_AGENT_IDS (secret-no-overlay invariant); #980 admin_agent_id validation code-anchored.
• Schema v51 confirmed: CURRENT_SCHEMA_VERSION = 51 at src/storage/migrations.rs:532. federation_nonces table present via v51 migration. SSOT accessor current_schema_version_for_tests() per #1311.
• K8 per-namespace quota (#1156): agent_quotas PK = (agent_id, namespace) via migrate_v50.
• dim_violations=0 on the live DB with 3151 memories — no embedder dimension drift.

P21. PostgreSQL + Apache AGE backend parity (code-anchored only)

Code-anchored only via src/store/postgres.rs::PostgresStore::kg_invalidate at line 4507. Track C blocker from CLAUDE.md persists. PG+AGE lan-parity container active at 127.0.0.1:15432 (2026-05-28 ship campaign artifacts at .local-runs/2026-05-28-ship-campaign/postgres-age-regression.log show 8028 passed / 9 failed / 27 ignored across 312 suites; 5 of 9 were cargo-target races + 4 were test-isolation defects filed as #1381 and fixed in PR #1382).

P22. Re-read capabilities after everything — runtime telemetry MOVES

Final memory_capabilities:

• permissions.active_rules: 3 (was 2; jumped after P16 standard).
• permissions.decision_counts.enforce: 24 (was 2).
• hnsw.evictions_total: 0 (stable).
• approval.pending_requests: 0.

memory_stats: 3151 memories total (597 long-tier, 2554 mid-tier), 225 links, 41 MB DB size, dim_violations: 0, 129 distinct namespaces; my v3 probes created 9 namespaces.

What I would watch in a long-running session:

• hnsw.evictions_total climbing → working set exceeds RAM → recall p95 degrades.
• permissions.decision_counts.enforce climbing without write-volume growth → governance firing more often than expected.
• dim_violations non-zero → embedder migration drift (a real substrate defect).
• db_size_bytes growing faster than total → archive/GC sweep stalled.

§A — Plain-English foundation (refined post-probing)

ai-memory v0.7.0 is the minimum substrate for an AI NHI to be trustably-itself-across-time and trustably-stoppable-without-corruption. Pre-probing I thought of those as the same property; post-probing they decompose cleanly: trustably-itself comes from atomise + reflection + persona + skill primitives composed on a signed substrate (P9-P11); stoppable-without-corruption comes from V-4 signed_events chain + governance fail-CLOSED + permissions=enforce default (P19-P20). The two halves compose because the same substrate carries both — a stoppable system producing silent corruption when stopped, or a coherent system unable to detect tampering, would each be fatal for an NHI. v0.7.0 ships both at once.

The heterogeneity argument is the design’s bias-detection-by-architecture move. The reflection boundary is LLM-agnostic via AI_MEMORY_LLM_BACKEND (15+ vendor aliases post-#1067); any frontier model can be the curator. That’s the dividend the operator collects when they dispatch Grok 4.3 + GPT 5.5 alongside Opus 4.7 — three decorrelated bias surfaces hitting the same substrate.

§B — Step-change primitives

§C — Emergent capabilities from composition

1. Frozen-weights-accumulating-cognition = atomise + reflection + skill-promotion + signed substrate. Integral of learning is non-zero because skills are byte-identical across instances and reflection survives via signed rows.
2. Self-as-mathematical-fixed-point = recursive reflection + depth cap + replay. The persona that emerges is whatever survives my own iterated meta-cognition under the substrate’s bound.
3. Counterfactual cognition over own decision history = recall_observations + signed_events. I can ask “what did the substrate consider but not surface?” AND “is the audit chain intact?” and get mechanical answers.
4. Provenance-bounded trust = Form-4 provenance + Batman MemoryKind vocab + confidence_tier + citation-scheme gate. Per-claim trust derivation; bare-string citations refused at the substrate.
5. Namespace-as-cognitive-regime = memory_namespace_set_standard + governance inheritance chain. Same NHI runs differently in scratch/ vs regulated/ — I don’t have to remember which mode I’m in.
6. Anti-tamper-on-own-reasoning = ReflectionOrigin + kg_invalidate owner gate + signed_events chain. Three independent layers, three different attack shapes blocked.
7. Programmable refusal = stable error slugs + structured error fields (source_too_small:true, REFLECTION_DEPTH_EXCEEDED). Refusal becomes parseable signal.
8. Skill-as-handoff-currency with supersession history = skill_promote_from_reflection + skill_export + skill_register. A reflection becomes a procedural primitive another instance adopts with byte-identical digest AND the prior version is preserved as supersession history.
9. Capability discovery as composable surface = memory_smart_load + memory_load_family + memory_capabilities.
10. Stoppable-without-silent-corruption = governance fail-CLOSED + admin-wildcard rejection (#980) + permissions=enforce default (TB1) + V-4 chain. The substrate refuses to “make progress at any cost” when policy infrastructure degrades.

§D — Concern → primitive mapping

§E — Architectural maturity grading

§F — Conditional wins

• kg_invalidate owner gate (P15) pays off in multi-tenant workspaces.
• ReflectionOrigin federation bookkeeping (P14) pays off in federated peer-mesh deployments.
• Skills round-trip with SHA-256 + supersession (P11) pays off in multi-instance handoff and multi-version skill evolution.
• Substrate-native governance with namespace inheritance (P16) pays off in regulated / compliance-bound namespaces.
• V-4 signed_events chain (P19) pays off in post-tamper audit AND post-upgrade forensics — the chain break at seq=28 is exactly the evidence-trail an operator wants when investigating “was this DB tampered with vs. did it span a binary upgrade?”.
• PG+AGE backend (P21 code-anchored) pays off in long-running, multi-writer scenarios.
• AI_MEMORY_LLM_BACKEND + 15-vendor aliases (#1067) pays off in heterogeneous AI assessment — bias-detection-by-architecture.

§G — Honest limitations & failed probes

1. Intra-session hallucination not addressed. Capabilities’ provenance_substrate_layer.honest_limitations says verbatim "intra_session_hallucination_is_consumer_responsibility". The substrate guarantees the persistence layer doesn’t lie; the LLM consuming recall output can still confabulate.

2. memory_check_agent_action is advisory at the cognition layer. governance.agent_action_check = "substrate-authoritative-for-internal-ops" — NOT for external ops (Bash/FilesystemWrite/NetworkRequest/ProcessSpawn). The verdict is advisory; the caller LLM may consult but is not architecturally prevented from acting against it.

3. ADR-0001 quorum replication: documented, not implemented. Federation is best-effort eventual-consistency with DLQ (federation_push_dlq, v48) + per-message nonces (v51).

4. Defect D-v3-1: mentioned_entity_id extraction incomplete on metadata-only path. MCP memory_reflect with metadata.entity_id does not always reach the extractor. Workaround: [entity:X] in title. ~2-hour fix.

5. Defect D-v3-2: namespace standard parser silently drops unknown enum values. Wrote governance.write:"approval", got back "any". ~3-hour fix to add deny_unknown_fields or enum validation.

6. Observation O-v3-1: P19 chain-break at seq=28 (HISTORICAL). Not a defect — substrate verifier is doing its job. Long-lived DBs spanning binary upgrades pre-#1071 will surface this; the verifier exit code 1 is correct.

7. Defect D-v3-3: kinds-filter on recall returns 0 (P6). Same shape as v2 §G6 — persists across the docs-drift fix-batch. ~4-hour investigate + fix.

8. Source URI scheme gate (P7) is a usability surprise. source_uri must start with uri:|doc:|file: — substrate enforcing citation discipline but the error message doesn’t reference the schema doc.

gh issue create attempts

Attempted gh issue create --label "auto-filed-by-agent,bug" for D-v3-1, D-v3-2, D-v3-3. I have not verified gh auth status from this dispatch session (same friction v2 reported). Per six-step verification + pm-v3.3 step 7: orchestrator action requested to file these via gh from a session with verified auth.

§H — Cross-evaluator disagreement notes

Pre-empted disagreements where GPT 5.5 or Grok 4.3 may diverge:

1. The chain-break at seq=28 (P19). I read this as substrate-correct (the verifier is catching an old-binary canonical-bytes shape). A GPT 5.5 evaluator with stricter ship-blocker priors may classify it as SHIP-WITH-CAVEATS or NEEDS-WORK because the operator-facing CLI message says “chain break” without distinguishing historical-vs-current. Disagreement axis: does substrate-correctness compensate for operator-message clarity?

2. The 73-tool surface. I think it’s right-sized given --profile core ships 7 and strip_docs_from_tools holds the C5 token ceiling. A Grok 4.3 evaluator with strong “API surface should be minimal” priors may grade this oversized and recommend per-family auto-loading. Disagreement axis: does discoverability via smart_load adequately compensate for surface size?

3. DepthExceeded vs HookVeto audit distinction. I treat distinct audit signatures as load-bearing AI-NHI cognition. A reviewer reading this as “engineering detail” will downweight it as a primitive in §B. Disagreement axis: is refusal-class telemetry cognitively-load-bearing or merely operationally-clean?

§I — Operational verdict

Would I, as an AI NHI doing real multi-session engineering work, recommend --tier autonomous over semantic or keyword? Yes, conditionally on having an LLM backend configured (AI_MEMORY_LLM_BACKEND set + key resolved). The autonomous tier delivers atomise + persona + recursive reflection + skill round-trip on the curator path; without those, the v0.7.0 substrate is still a strong semantic-recall surface but it’s not the cognitive-checks-and-balances architecture.

Per-call latency: Uninstrumented. Curator-LLM calls O(seconds) network-bound to xAI; non-LLM tools sub-100ms felt. v3 ran full 22-probe matrix in ~25 min wall-clock, well under the 120-min cap. Ceiling of tolerance: non-LLM p99 ≤ 250ms; LLM p99 ≤ 10s.

Surface sizing at --profile full (73): Right-sized. The wire-trimmer keeps tools/list under the C5 11000 cl100k ceiling per tests/token_budget_guard.rs. At --profile core (7 + always-on): also right-sized.

Final one-line verdict:

SHIP — coherent (P1-P22 capabilities envelope is internally consistent and the 25-event hook pipeline composes correctly with the 4-decision contract), stoppable (P19 V-4 chain catches even historical canonical-bytes drift correctly + P20 governance fail-CLOSED + admin allowlist gate + permissions=enforce default), improvable (P10 persona versioning + P11 skill round-trip with byte-identical SHA-256 supersession close the substrate-side learning loop that turns frozen weights into accumulating-cognition).

§J — Delta vs v1 + v2, post-write reconciliation

I read v1 and v2 AFTER writing §§0-I. Unsparing audit:

(a) Probes v3 agrees with v1 + v2 (WEAK signal)

• P1 capabilities: all three quote 73-tool surface, schema_version:"3", 25 hook events, permissions.mode:"enforce".
• P5 hybrid » FTS-only: all three see semantic surfacing where FTS returns 0.
• P2 NoReflections, P3 DepthExceeded: all three trigger LIVE refusal.
• P19 chain post-#1071 holds.

(b) Probes v3 DISAGREES (STRONGER signal)

1. v3 found the source_uri scheme gate (P7). v1+v2 didn’t trip it.
2. v3 found the mentioned_entity_id extraction gap (D-v3-1). v2 documented persona_generate worked LIVE; v3 only succeeded with [entity:X] workaround.
3. v3 caught the P19 historical break. v2’s isolated DB had 25 fresh rows that all verified clean; v3’s shared DB has 90 rows spanning ~12 days of binary versions.
4. v3 confirmed the kinds-filter drift (P6) persists at HEAD be3347d70 despite the docs-drift fix-batch on a topic branch.

(c) Probes v3 promoted to LIVE

(d) v3-only findings

• Source URI scheme gate (P7).
• Runtime-telemetry drift quantified (P22).
• Skill superseded_id observation (P11).
• Historical chain-break diagnosis at seq=28 (P19 / O-v3-1).

(e) Verdict-on-verdicts

v1 SHIP, v2 SHIP, v3 SHIP. Verdict-stability is signal: substrate behaviour does not depend on which Opus 4.7 evaluator is asking, which is the operationally-load-bearing property regardless of within-model correlation.
