Its score characterizes semantic +message recall plus answer quality. It is not, by itself, a sampled extraction-prompt quality test. + + +The report contains AgentEval's overall, task-averaged, per-type and per-question results alongside +per-question AgentMemory stored/retrieved counts.

The profile pins Neo4j 5.26 and uses +the configured real Azure OpenAI embedding deployment for both persisted history and recall queries. +The tool probes the provider's vector dimension before creating the Neo4j index and records the +embedding deployment and dimension in the report fingerprint. The configured chat deployment answers +questions and acts as AgentEval's judge. AgentEval 0.16 explicitly requests judge temperature zero; +for deployments that only accept their default temperature, the tool translates only that unsupported +zero to provider-default while leaving AgentEval's prompt and binary scoring unchanged. + +A valid run requires exactly two LLM calls per question (one answer and one judge), one AgentMemory +telemetry record per question, nonzero stored messages, nonzero recalled items, and no embedded agent +or judge errors. If any guard fails, the command exits nonzero and writes an `accepted=false` +diagnostic report. That report omits questions, answers, model responses, and exception text; it +contains only safe validation categories, public question ids/types, durations, and aggregate +storage/recall counts. + +## Reading a score + +The first run is a characterization baseline, not a product-quality pass/fail gate.

At the shipped 0.2 factor that let the access count alone decide retention: - a memory recalled ONCE scored 0.2, permanently above the 0.1 MinRetentionScore, so it could never be pruned however stale it became; - access_count = 10,000 scored 2,000 against a [0,1] cosine blend; - in recall re-ranking the [0,1] clamp turned this into saturation instead of runaway: five accesses pinned retention at the ceiling, so every frequently-recalled item tied there and the confidence and recency signals the convex blend exists to carry were destroyed. Damp the term logarithmically, cap it with MaxAccessBoost, and fold it inside the same exponential decay as confidence, so frequent access slows forgetting rather than preventing it. Applied identically at all four sites that share the formula so they cannot drift. Two existing tests characterized the linear ramp rather than an invariant and are updated to the damped values; the zero-confidence test keeps its real invariant at the new magnitude. The Cypher assertion now also rejects a regression to the linear form. BEHAVIOR CHANGE: pruning now deletes stale high-access memories that were previously exempt. Enhanced-profile ranking order changes; Parity (weight 0) is unaffected.

Structured mode allocates a zero message budget, so `recalled` is empty, the rankedItems/recalled count invariant passes vacuously at 0 == 0, and GoldSessionRecallAtK returned 0.0 rather than null. LongMemEvalPostRunDiagnostics then read that 0.0 and labelled every failed structured question a "retrieval-miss" — manufacturing a product defect out of a harness limitation, and failing open because the run validator never inspects retrieval evidence. Pass the configured message budget into the evidence build and treat gold metrics as not observable when it is zero. Classification gains an explicit "retrieval-not-observable" outcome so an unobservable metric is neither blamed on retrieval nor allowed to fall through to an answer-synthesis verdict. A real miss stays a real miss: a nonzero budget that returns no gold hit still reports 0.0 and classifies as retrieval-miss. The AgentEval-side evidence envelope already attributes structured items through provenance and is untouched, so gold-session metrics remain available for Structured and Hybrid there.

They then compete for the recall budget on cosine similarity alone, and they win: in the accepted r8 run 240 of 300 final items were boilerplate, and both questions reported as retrieval failures returned 30 of 30, so no real source turn could rank at all. That makes the standing "retrieval needs better ranking" conclusion unsupported by its own evidence. Add a default-off --exclude-synthetic-messages selection mode: over-fetch three times the message budget, drop only the items the formatter's own origin flags identify, keep the provider's retrieval order, and take the first --max-relevant real source turns. Storage, embeddings, the vector query and the final item budget are unchanged, and filtering happens before the answer prompt and both evidence paths so all three boundaries observe the same items. RetrievalRank is preserved so the candidate-set ceiling stays reportable; only ContextRank is renumbered. Items whose origin is unknown are kept, because dropping what cannot be classified would silently shrink the budget. The mode is recorded in the report fingerprint so a filtered run can never be compared against the unfiltered control by accident. Default off: unfiltered recall remains the immutable comparison control.

A provider returning the right NUMBER of empty vectors had them assigned verbatim and persisted, and an empty list is not null, so such a message passed recall's `embedding IS NOT NULL` filter; cosine then yielded null and `null >= $minScore` dropped every row. The message was stored and permanently unsearchable with no error raised anywhere -- the LongMemEval "596 stored / 0 recalled" signature, which for weeks looked like a retrieval-ranking defect and nearly justified funding hybrid BM25 work. Validate contents, not just count: a non-blank message whose vector comes back empty is replayed individually, and if it is still empty the write fails. Blank content is different in kind -- the orchestrator returns an empty vector for it by design -- so it is stored as-is and simply never matches a semantic search. Also require size(node.embedding) = size($embedding) in the session-scoped message search, so a corrupt vector surfaces as a detectable condition instead of silently matching nothing. Verified live: the 10-question seed-42 control moved question 3 from `retrieval-empty` to `storage-error`, proving the embeddings for that question really are empty and that the failure is now reported where it happens rather than three layers downstream.

Question 2e6d26dc contains one 41,855-character turn (~10,464 tokens), which exceeds the embedding model's 8,191-token input limit. Two behaviours then combined: - the provider rejects the WHOLE request when a single input is over the limit, and EmbedBatchAsync caught that and left every slot empty, so one bad turn blanked all 596 of the question's messages; - EmbedAsync converts any provider exception into an empty vector, so the failure never surfaced. Before batching, an oversized message cost one message. LAB-R1 batched all of a question's messages into one request, which turned that into a whole-question blackout -- and it read downstream as a retrieval-ranking defect, which is what it was nearly funded as. Cap embedding INPUT at a conservative 32,000 characters: stored content is never truncated, only the text handed to the embedder, so a long message stays complete and searchable instead of unsearchable. On batch failure, retry item by item so the blast radius is the offending input rather than its neighbours. Only 4 of the 500 dataset questions contain such a turn, which is why this hid for so long. Verified live: the 10-question seed-42 control returns to exit 0 with zero validation issues -- 20/20 LLM calls, no empty questions, 70.0% overall and 69.4% task-averaged, matching the accepted r8 baseline it had stopped reproducing.

A range index that failed to populate was therefore invisible: Neo4j keeps answering queries by falling back to full scans, so the only symptom is unexplained slowness that grows with the data. Neo4j caps index keys at roughly 8 KB and nothing bounds fact property length, so this is a live hazard for the pending Fact merge-key index rather than a hypothetical one -- the index would be created, fail, and silently never exist. Query all index states and fail bootstrap with the offending names when any is FAILED. POPULATING is deliberately not treated as a failure; it is the normal asynchronous build state. States are filtered in memory because a literal in a Cypher WHERE clause trips the repository's parameterization guard.

These two arms bracket it. Both run the identical sample, seed, answer deployment and judge as the memory arms, and neither starts a container or makes an embedding, extraction, storage or recall call. Whether the full history fits is decided by the provider rejecting the prompt, not by a token estimate. Measured first: all 500 dataset questions are 113,750-128,489 estimated tokens (mean 122,326), so every question sits inside the estimator's own error bar against a 128k window - an estimator would have turned a measurement into a coin flip. A context-length rejection is recorded as an explicit skip and excluded from fitted accuracy rather than scored wrong; any other provider failure stays fatal. The arm gets its own exact validator rather than an exemption carved into the AgentMemory one, which is untouched: same 2N base-call contract including BUG-J1's diagnostic-retry separation, plus provider failures accepted only in the exact number of recorded context-window skips. System prompts necessarily differ from the shipped "using only the retrieved memory below" - with no memory block that manufactures abstentions and would understate the floor - so neutral variants are used and recorded verbatim in the report as a stated limitation. Unit 3,615/3,615 unchanged, LongMemEval 94 -> 104, Release 0 warnings/0 errors.

A small sample From 3199179696dd47191494d017795c8e50f3c67a89 Mon Sep 17 00:00:00 2001 From: Jose Luis Latorre Millas Date: Fri, 7 Aug 2026 19:23:24 +0200 Subject: [PATCH 043/112] fix: restore time to the LongMemEval answer context LongMemEval session dates reach the harness in exactly one place: AgentEval's "--- Session N (2023/05/20 (Sat) 10:19) ---" boundary markers. G3B.1 drops those as formatter boilerplate, which took every date with them, and BuildAnswerPrompt emitted only [role] content with no current date. The filtered arms therefore carried no time information at all, and all three failing questions are temporal. Proven from runs already on disk, not assumed: the unfiltered control passes 8077ef71 and 4d6b87c8, which the filtered run fails. G3B.1 is a trade, not a pure win - it gained on other types and broke the temporal ones, which is why overall accuracy stayed pinned at exactly 70.0% across both. The date survives on each real message as sourceTimestamp provenance and Neo4jMessageRepository round-trips Metadata on read-back, so it is restored from recalled product data rather than from evaluator-side knowledge. Applied to the full-history reference arm and the oracle diagnostic in the same commit. Handing dates only to the memory arm would manufacture a win. Ordering is deliberately left unchanged so this moves one variable. Unit 3,615/3,615 unchanged, LongMemEval 104 -> 110, Release 0 warnings/0 errors.

Measured target: gpt4_7abb270c spent 14 of 30 slots on two sessions while a required sixth gold session, present in the candidate pool, got none. With cap=3 gold session recall moves 0.833 -> 1.000, distinct sessions 8 -> 14, item count still exactly 30, and the failure re-attributes from retrieval-miss to answer-synthesis-failure. --chronological-context presents the same items in conversation order rather than similarity-rank order. Null result, retained: neither moved the score. Both were predicted to flip gpt4_7abb270c and neither did. The guard held - no currently-passing question regressed - so the cap is kept for strictly better evidence coverage, not for a score gain it did not produce. Remaining diagnosis is now exact: 5 of 6 answer-bearing turns are in context. The sixth museum is named in a passing aside inside a long turn about something else, so the turn-level embedding does not represent it. That is granularity, not ranking, ordering or allocation.

All of that is liveness, not adequacy: three facts learned from 474 sessions passes every existing guard. Adds the question that decides whether Structured can work at all. Per question, at graph read-back and before any evaluation call is spent, counts learned items whose EXTRACTED_FROM provenance lands in an answer-bearing session, plus a learned-items-per-source-message ratio so a too-thin build is loud rather than silently green. Zero gold-derived items yields a new attribution, extraction-lost-evidence, which outranks BUG-E1's retrieval-not-observable: "cannot tell" should lose to a proven extraction loss. Until now a Structured failure could not be separated into extraction lost the fact, retrieval missed it, or the reader failed. The probe default is null meaning not measured, never "fine" - a probe that cannot answer must not assert coverage it never checked, so the absent case falls through to the existing verdicts unchanged.

Structured lost exactly the temporal questions (8077ef71, gpt4_483dd43c) that Raw answers, and the cause is the same defect G3B.2 fixed for messages, left live on the structured channel: the answer prompt emitted "[entity] Name (Type)" and "[preference] text" with no date anywhere, so the reader could not place a learned item in time. Entities, facts and preferences all carry SourceMessageIds and those messages carry the real conversation date, so items are now dated from data recall already returns - no extra query and nothing evaluator-side. An item evidenced across several dates shows the range rather than one date, because collapsing it would hide the supersession a knowledge-update question turns on. --retain-prepared-volumes keeps the cold build on disk after the run. Measured motivation: two consecutive builds of the same frozen plan produced different graphs - 10,409 vs 10,330 learned items, every question different, one 12% apart - so extraction is not deterministic at temperature 0 and a rebuild cannot reproduce a failure. Retention makes cleanup the operator's responsibility, so the three volume names are printed. Unit 3,615/3,615, LongMemEval 121/121, Release 0 warnings/0 errors.

The prepared-pair evaluation arms set none of ExcludeSyntheticFormatterMessages, MaxItemsPerSourceSession or ChronologicalAnswerContext, so Structured and Hybrid were measured through the uncorrected message pipeline - an unfair comparison against our own product, and every Structured/Hybrid number to date is suspect. Hybrid was the visible casualty: 66% of its message slots were AgentEval formatter boilerplate, and its two failing multi-session questions received 0 and 2 real turns out of 15. It was effectively structured-only with 15 wasted slots, which is why it tied Structured exactly. Root cause of the flooding, measured against the retained graph rather than assumed: one question holds 46 byte-identical copies of "Understood. Starting a new conversation session." Identical text yields an identical embedding and therefore an identical cosine score, so the whole duplicate set ties and monopolises top-K together. Synthetic messages are 21% of the corpus but 66% of retrieved slots. Recall has no content- or vector-level dedup, so this is a product defect, not a harness artifact: any agent emitting repeated boilerplate floods its own recall the same way.

AgentEval's LongMemEvalHistoryFormatter.cs:39 fabricates a conversation turn per session boundary - the user "says" "--- Session 12 (date) ---" and the assistant "replies" "Understood. Starting a new conversation session." It does this because IHistoryInjectableAgent accepts only (user, assistant) pairs and has no channel for session structure, so a session-structured dataset gets smuggled through as fake dialogue. That single cause produced both symptoms chased this session. The session date lives inside the fabricated turn, so dropping those turns lost the dates worth 20 points, while keeping them let 46 byte-identical copies in one question produce 46 identical embeddings that tie on cosine and monopolise top-K. Synthetic messages were 21% of the corpus and 66% of retrieved slots. Fixed at the write boundary rather than at retrieval. The assistant half is pure fabrication carrying zero information; the user half's session id and date are already attached to every real message as provenance metadata, so nothing is lost by not storing either. An unclassifiable message is still kept - dropping what we cannot identify would silently lose real evidence, which is worse than the flooding this prevents. Two existing assertions characterized the old store-everything behavior and are updated to the new one, strengthened rather than relaxed: the fabricated pair must now be provably absent, not merely uncounted.

Measured on a real extracted graph: "Ava and Lily"/were_born_in/"April" and "Ava and Lily"/were born in/"April" became two nodes, as did "User"/is planning and "user"/is planning. That graph held 575 facts across 407 distinct predicates - 1.41 facts per predicate - which also makes any query keyed on a relation impossible, and directly caused Structured mode to fail counting questions: the five births needed to answer "how many babies were born" were all present but fragmented across duplicate nodes competing for ten fact slots. Identity now uses a canonical trio computed once in C#; the raw subject, predicate and object are still written for display and audit. So this is not a new deduplication mechanism - it repairs the one that already existed. Deterministic only, by design: no embedding or fuzzy similarity folds one predicate into another. "bought" and "sold" are semantically adjacent and opposite, and merging them would silently invert facts in a way ordinary tests would not catch. Only meaning-preserving differences collapse - case, surrounding whitespace, and word separators. The canonical form is never recomputed in Cypher: ToLowerInvariant and Cypher's toLower disagree on U+0130, which would produce two keys for one relation and reintroduce the fragmentation this removes. Two tests asserted the old merge key and are updated to the new one, strengthened to also require the raw triple is still persisted. Cypher snapshot regenerated (BOM stripped).

BUG-J1 accounted for *our* post-run diagnostic retries. AgentEval separately retries an unparseable judge verdict internally under JudgeFailurePolicy.RetryThenInconclusive and does not report how many times, so an exact call count is not achievable from outside the library. Demanding one does not add safety - it rejects valid runs nondeterministically, which already cost a no-memory floor run and a canonical-identity verification. The correctness properties stay exact and are what actually guard a score: one answer call per question, one valid yes/no verdict per question, verdict and recorded correctness must agree, and no fabricated results. The call count becomes a bounded cost signal instead, capped at the configured retry allowance per question, so runaway judging still rejects. This is a contract correction, not a relaxed guard: previously the run was rejected for a cost figure the library controls while the correctness checks all passed.

Canonical identity was never reaching a real cold build. Cause: facts have two write paths. FactQueries.Upsert/UpsertBatch received the canonical keys; FusedPersistenceQueries.FactUpsertBatch did not - and the extraction pipeline uses the fused one. Every unit test passed because they cover the path production does not take. Adds cross-write-path parity tests so this cannot recur: every fact MERGE must key on the canonical trio, must still persist the raw triple, and must not merge on raw text. These fail against the previous commit. Note what this says about the earlier claim: 07cb99d asserted canonical deduplication shipped. It did not. The unit suite, the Cypher snapshot and a green build all agreed with a change that had no effect on the real path, and only the live falsifier caught it. Unit 3,632 -> 3,641, Release 0 warnings/0 errors, snapshot regenerated.

Measured: Structured's two remaining failures are counting questions - five births across four sessions, four furniture events - all present in the graph by inspection, and recall returned a similarity- truncated subset of a ~962-item pool. Miss one birth and the answer is four. Adds FactQueries.SearchByCanonicalPredicates: every fact an owner holds under a set of canonical predicates, bounded and deterministically ordered.

That graph held 700 facts under 421 distinct predicates: a vocabulary almost as large as the data, which is what happens when nothing tells the extractor which relations already exist. MemoryPredicateVocabulary is the set of established relations, to be shown to the extractor so it reuses them rather than inventing a phrasing per sentence. ConcurrentDictionary keyed on the canonical form: O(1) admission on the extraction hot path, no lock. Deterministic only. Admission matches the canonical form and nothing else - no embedding or similarity folding, because "bought"/"sold" and "likes"/"dislikes" sit one threshold apart and mean opposite things, and merging them would silently invert stored facts. First spelling wins, so an established relation never drifts between runs and queries can rely on its name. Growth is capped because the vocabulary is injected into a prompt; a predicate beyond the cap is still returned and usable, so a full vocabulary degrades to today's behaviour rather than losing a fact.

The extractor invents a predicate per sentence because nothing tells it which relations already exist: 700 facts under 421 distinct predicates, with one birth arriving as "was born", "was born in", "were born in", "had" and "welcomed". That left counting questions unanswerable even after a relation could be retrieved whole, because no single relation held more than three of the five births. Reconciling phrasings afterwards is not safely possible - "bought" and "sold" sit one similarity threshold apart and mean opposite things - so the vocabulary is applied where the phrasing is chosen. The seed is curated, not mined per run. A vocabulary accumulating during a run would make each call's prompt depend on which concurrent extraction finished first, so identical input could yield different prompts: the precise property that made an earlier Structured score sequence unattributable. A reviewed list can also be checked for the one mistake that matters, silently omitting one side of an opposing pair, so both polarities are present by design. The extractor is told to prefer these relations, never to be limited to them; a model restricted to a fixed list would drop facts needing a new relation. An empty vocabulary returns the original prompt byte-for-byte, so callers that do not use this - including the frozen batch plan, whose estimated input totals depend on prompt size - are unaffected. Tests fail against the previous commit. Unit 3,655 -> 3,660, LongMemEval 125/125, Release 0 warnings/0 errors.

RecallOptions.ExpandFactsByPredicate turns it on; similarity-ranked facts stay in order at the front and every fact sharing their canonical predicates is appended, deduplicated by id and capped by MaxExpandedFacts. Top-K is a relevance cutoff with no completeness guarantee, so an aggregation question cannot be answered from it - miss one of five births and the count is four. Expansion is what makes a relation arrive whole, and it only became possible once predicate_key existed, since the five birth phrasings previously shared no key to expand on. Two API constraints shaped this. The new parameters are a separate overload and a default interface method rather than optional parameters on the existing signature, because adding optional parameters to a published interface breaks every implementor. And the assembler calls the wider overload only when expansion is enabled: NSubstitute intercepts default interface members and returns null, so routing the default path through it broke eight assembler tests.

The guard was right; the change was wrong. Evidence building resolves every retrieved fact back to a source turn using a map of the *current question's* messages, and throws when a source cannot be mapped. Top-K facts always mapped. Expansion returns a relation across the whole owner, so an expanded fact may legitimately carry provenance outside that window - and the throw could not tell that apart from genuine corruption. Expanded facts are now marked as they enter the context, via fact metadata, and evidence building treats that as its own category: kept in the answer context, attributed with an out-of-window source. The throw is untouched for every unmarked fact, so provenance corruption is still detected. Two alternatives rejected. Widening the origin map to the whole owner would silently redefine what gold attribution means and invalidate every retrieval number measured so far. Restricting expansion to the current window would defeat its purpose, since completeness beyond top-K is the feature. Tests cover both categories: an expanded fact with out-of-window provenance is accepted, an unmarked one still throws. Unit 3,660/3,660, LongMemEval 127 -> 130, Release 0 warnings/0 errors.

LongMemEvalAgentEvalEvidence.Build rejects an envelope above QuestionEvidenceEnvelope.MaximumReferences = 100, and that cap counts entities, facts AND preferences - not the fact budget alone. A structured arm at --max-relevant 30 already spends 30 references, so the old MaxExpandedFacts default of 100 produced up to 130 and overflowed on nearly every question. This explains every observation, including the one that did not fit the provenance theory: exactly one question survived, because its expansion returned few enough facts to stay under the cap. Two independent bugs were stacked here. The earlier provenance fix (fffc2f8) was real and moved answer calls 0 -> 1; this cap then took over. Fixing the first and assuming the symptom had one cause is what cost the extra rebuilds. Part one: default MaxExpandedFacts 100 -> 60, comfortably inside the envelope. Part two: validate at construction instead of discovering it mid-run - the worst case is every category filled plus every expanded fact, and it now throws with the arithmetic spelled out before a single extraction call is spent. Deliberately not raising MaximumReferences: it is AgentEval's contract and exists to bound the envelope. Completeness and evidence accounting genuinely compete for one ceiling, and the budget must respect it. One wiring-test fixture used 77 expanded facts against a 30-message Raw budget (107 references) and is corrected to 50 - the guard was right about it.

These are the two highest-severity. 1. Canonical() folded '-' and '_' into spaces for subject and object as well as predicate, so "-5" and "5" produced one merge key and a quantity silently MERGEd onto its negation. Separator folding is correct for a predicate, where was_born and "was born" are one relation under two naming conventions, and corrupting for a value, whose punctuation carries meaning. Split into CanonicalValue (trim, lower, collapse whitespace only) for subject/object and Canonical for predicate. Every test used verbs, so none could have caught it. 2. LongMemEvalReferenceArmValidator still enforced the exact-2N judge contract that 4b37f8e replaced with a range in LongMemEvalRunValidator. There are two independent implementations of one contract and only one was updated - the third instance this session of a change reaching one of two paths. The reviewers found the artifact: longmemeval-reference-nomemory-20260807T173250Z was rejected with 12 judge calls for 10 questions, which is the floor run 4b37f8e's own message cites as already lost, then fixed in the wrong file. Its comment claiming parity with the memory arms was false. Correctness stays exact in both validators: one answer call per question, one valid verdict per question. Only the call count, which AgentEval controls and does not report, is a bounded range. Unit 3,660 -> 3,666, LongMemEval 135/135, Release 0 warnings/0 errors.

Fact identity moved to canonical keys, so facts written by an earlier version carry no *_key properties: a re-extracted triple never MERGEs onto its existing node and duplicates, and SearchByCanonicalPredicates filters on predicate_key, making every pre-existing fact invisible to expansion. That affects shipped 1.x consumers, not just the benchmark. Deliberately NOT a .cypher migration, even though MigrationRunner exists and is the natural home for a schema change. Canonicalisation must be computed in C#: Cypher's toLower() and .NET's ToLowerInvariant() disagree on U+0130, so a Cypher backfill would write keys the repository's own writes never match - silently reintroducing the fragmentation canonical identity removes. The rule "compute the canonical form once, in C#, never recompute it in Cypher" was recorded when that shipped, and it rules out the obvious migration path. Rejected alternatives: dual-key read keeps two identity schemes alive forever in every fact query; requiring re-extraction is unacceptable for a shipped 1.x library, since users would accumulate duplicates silently and re-extraction costs real provider spend. Selecting on predicate_key IS NULL makes it idempotent by construction and resumable; ApplyCanonicalKeys targets facts by id and contains no string rewriting, which a test pins so the Cypher-side computation cannot creep back. Cypher inventory 147 -> 149 deliberately, snapshot regenerated. Unit 3,666 -> 3,680, Release 0 warnings/0 errors.

SearchByCanonicalPredicates hard-coded `f.owner_key = $ownerKey` with `scope.OwnerId ?? OwnerKeyShared`. That (1.2) never matched shared facts even when MemoryScope.IncludeShared was set, so the "relation whole" guarantee was false for any store using shared memory, and (1.3) coerced a null-owner scope to the shared bucket, returning nothing exactly where top-K returned everything. Now mirrors GetBySubject: an owner filter only when one was requested, shared facts included unless explicitly excluded, scoped by owner_id like every other fact read. This is the "check whether a second implementation exists" rule applied to semantics rather than to code paths - the correct behaviour was already written down four lines away. The const became an owner-conditional method, so the Cypher inventory drops 149 -> 148 (methods are excluded, as with GetBySubject). One existing test pinned the buggy owner_key form and now asserts owner_id. Three new tests: shared included when allowed, excluded when forbidden, and no owner predicate at all when no filter was requested. Unit 3,680 -> 3,679 (net of the inventory change), LongMemEval 135/135, Release 0 warnings/0 errors.

The checkpoint fingerprint identifies the configuration whose cold-build wall time the checkpoint projects. It carried PreparationWorkers but neither MaxConcurrentBatchesPerExtraction nor MaxConcurrentExtractionBatches - the two knobs that actually set provider concurrency, and therefore the time being projected. Two runs with materially different concurrency produced the same fingerprint, so their projections could be compared as though equivalent, and a stale projection could be carried into an acceptance it did not describe. Verified red-first against the committed version: PreparationWorkers was present, both concurrency knobs absent, so two of the three theory cases fail on HEAD~1. Consequence, expected and not drift: checkpoint fingerprints change value. The plan already forbids copying stale fingerprint or token figures into an acceptance, so fresh values must be recorded. Tests assert against the hashed payload itself rather than the options type, because the defect was a property existing on options but never reaching the hash - exactly the distinction that made it invisible.

This adds the driver: read unkeyed facts in bounded pages, compute the three keys in C#, and UNWIND them back, looping until none remain. Ordering is the defect's whole substance, so it runs inside BootstrapAsync before completion is reported: a fact written between an upgrade and the backfill would MERGE onto a fresh node and duplicate anyway, and bootstrap is the only hook guaranteed to precede repository writes. Keys are computed with the same methods the write path uses - CanonicalValue for subject and object, Canonical for predicate - so a migrated fact and a freshly written one land on the same node. Never computed in Cypher, because toLower() and ToLowerInvariant() disagree on U+0130. Idempotent by construction (selects on predicate_key IS NULL) and resumable, so a re-run over a migrated store does nothing and an interrupted migration continues where it stopped. Four wiring tests assert the call site and its ordering rather than the capability, since a query with no caller is exactly what shipped twice this session. CanonicalKeyBackfillRow is a named type rather than anonymous so the read shape can be stubbed; six DDL fixtures now model an already-migrated store.

Adds --reuse-prepared-volumes and routes volume creation through AdoptAsync when it is set, so a retained cold build can be attached instead of rebuilt. It then refuses to run. That is deliberate, not an oversight: the branch that skips preparation does not exist yet, so without it the run would attach to a retained build and extract on top of it - destroying the graph the operator asked to keep, which is worse than not having the feature. The error names what is missing rather than failing obscurely. Two constraints recorded in the guard for whoever finishes it: the seam is the preparation try/finally (everything after CloneFrozenBaseAsync is reusable unchanged), and the reused preparationId must be read from the sealed manifest rather than generated, because the per-question scope hashes derive from it and a generated one makes every question trip prepared-manifest-mismatch. Per the session's own rule, this is built-not-wired and claims nothing: Phase 2 is not complete and no cost reduction has been measured.

The cause was not the volume lifecycle: BeginBasePreparation and MarkBaseContainerStopped both run unconditionally, so an adopted volume does reach Frozen, and that guard would have thrown InvalidOperationException rather than a NullReferenceException. The cause was batchExecution, assigned only on the preparation branch and dereferenced through the null-forgiving operator in three places while serializing. The preparation section moves to LongMemEvalReportProjection so the reuse shape is testable; red reproduced the live message exactly. Unperformed work is now reported as null rather than 0, because a zero would be a fabricated measurement of work that never happened, and performedByThisRun plus reusedPreparedVolume keep a reused run from reading as a cold build in a ledger. Reading the output path found a worse second defect: it was keyed on the preparation id, which a reused run inherits, so a reused run would have overwritten the accepted report of the cold build it reused. A reused run now gets its own run id and keeps the preparation id as scopeRunId. The orphan sweep was specified for containers left by killed runs. Measured first: docker ps -a was empty and every volume reported zero links, so the reaper had removed them all. The real leak was 25 orphaned volumes holding about 17.2 GB, so the sweep targets volumes. Selection is pure and tested; the minimum-age guard is what makes it safe against a concurrent run, and removal asks the daemon rather than pre-checking attachment. --force is never passed. Retrieval flags now appear in the report fingerprint. Without them two runs over the same frozen graph are indistinguishable in the artifact, which is exactly the comparison reuse exists to make. Verified live: exit 0, zero validation issues, 4m35s, zero extraction calls against 22 minutes and 121, and the sweep reclaimed 24 of 25 volumes while keeping the adopted base.

It was a Structured clone whose base had already been removed, so "clones are cheap to regenerate" was false for it: it was the only copy, and it is gone. Two guards, both red first. A clone whose base is no longer present is kept, because regenerability is a property of the pair and not of the name. And an explicit pin file is honoured, because a sentence in a planning document stating that something is kept deliberately is invisible to a sweep. Two existing tests failed against the new rule. Their fixtures described clones with no base, which is precisely the shape now protected, so the fixtures were corrected rather than the rule relaxed. LongMemEval 150 -> 152; unit 3,683; Release 0/0.

Without a measured figure to cap it, complete means whatever a judge is willing to assert, which is the failure mode this track already rejects for escalation. Adds --predicate-distribution, a read-only verb that mounts an existing prepared volume and counts canonical predicates. It deliberately avoids the AgentMemory service graph, so counting relation names needs no embedding generator, no chat client, and no Azure credentials. The build/held-out split is pure and tested. It splits by predicate rather than by fact, because the question the held-out slice answers is whether the vocabulary covers relations it was not built against, which requires holding out whole relations. The hash is hand-rolled FNV rather than GetHashCode, which is randomized per process and would make the split differ between runs of the same command. Slice size is a ranked prefix rather than a per-item probability, so an empty held-out slice cannot silently turn the generalisation gate into a no-op. Emits predicate keys and counts only, never subjects or objects: a predicate is vocabulary, a subject is user content, and this table is written to an artifact. LongMemEval 152 -> 158.

Reporting only a global distinct count made the first measurement read as a catastrophic regression - 479 canonical predicates against a recorded 79-107 - when it was simply a different quantity. Measured per owner the same graph gives 62-133, mean 90.4, which sits inside the recorded band and confirms it. Also renames the raw-to-canonical ratio to canonicalizerFoldRatio. At 1.02x it was being read as failed consolidation, when the canonicalizer folds case and separators only by design: folding synonyms at write time would merge bought onto sold irreversibly. The vocabulary consolidation figure is the per-owner one.

A question naming several relations reaches only whichever of them retrieval happened to nominate. This supplies the relations from the question instead. Read-side only, and that asymmetry is the safety argument: clustering predicates over stored facts was rejected because merging bought onto sold corrupts meaning irreversibly, whereas a wrong entry here costs precision on one query and can never alter a stored fact. Two directions, one authored. The table is canonical to surface forms; the lookup index and the inverse index are both derived at load, so they cannot disagree. The inverse index exists because the write-side canonicalizer folds case and separators but deliberately never morphology, so one relation is stored under several keys: the measured graph holds planned with 839 facts and plans with 14 as separate predicate keys, and expanding on the canonical name alone would silently miss the smaller bucket. A surface form claimed by two relations is dropped rather than awarded to whichever was authored first, which would make resolution depend on table order. The dropped set is exposed instead of discarded, so an authoring mistake is visible, and a test asserts it is empty for the shipped table. Table content is grounded in the measured distribution rather than intuition, including the frequent predicates the extractor invented outside the offered vocabulary. It carries assembled and fixed, which schema.org supplies neither of - there is no AssembleAction and no RepairAction anywhere in the Action hierarchy - and which the known failing question needs. Stemming is a fallback for forms the table does not list, with length guards: is is the most common predicate in the measured graph at 26% of all facts, and naive -s stripping would reduce it to i. Measured against the real graph: 58 relations over 299 surface forms reach 87.6% of fact mass, against 78.1% for the extraction vocabulary alone. Not yet wired into recall, so this is a mechanism result and not a quality claim. Unit 3,683 -> 3,713.

Nothing recorded which tables produced a given graph or a given score. This is the same class of defect as the retrieval flags that were missing from the run fingerprint until earlier today: a setting that changes the outcome but leaves no trace in the artifact. Both hashes are order-independent, because a vocabulary is a set and reordering entries is an authoring change with no meaning; if order mattered, every cosmetic edit would invalidate comparisons for nothing. The table hash binds each relation to its own forms, so moving a surface form from one relation to another changes the hash even though the entry count does not - a hash over counts, or over the two sides separately, would miss exactly that. Grants the LongMemEval tool the same InternalsVisibleTo the CLI, bridge and benchmarks already have, rather than widening the public API for a diagnostic. Core multi-targets down to net8.0, where Convert.ToHexStringLower does not exist, so the hash uses ToHexString().ToLowerInvariant(). Unit 3,713 -> 3,722.

A question naming several relations - "did I buy, assemble, sell, or fix" - therefore reaches only whichever of them retrieval happened to surface, which is the measured cause of the surviving gpt4_15e38248 failure. The lexicon now supplies the relations from the question instead. Each named relation is widened to every form it could be stored under, because the write-side canonicalizer never folds morphology: the measured graph holds planned with 839 facts and plans with 14 as separate predicate keys, so expanding the canonical name alone would miss the smaller bucket - the same completeness failure expansion exists to prevent. An empty relation list reproduces the previous call exactly, and an unrecognised verb resolves to nothing, so both the option-off path and the no-match path are byte-identical to today. That is what keeps this from ever being worse than current behaviour, and it is covered by a test rather than asserted. Expansion previously returned early on an empty top-K because it had nothing to derive predicates from. A question that names its relations outright does not have that problem, so the early return now applies only when there is also nothing named. A further default interface method rather than optional parameters, for the same reason as the overload above it: the interface is locked under SemVer and optional parameters would break every implementor. ResolveQueryRelations is off by default and exposed as --resolve-query-relations, since nothing here becomes a default before it is measured. Unit 3,722 -> 3,728; LongMemEval 158; SK 54.

One relation known to two layers must have one definition. The extraction vocabulary is now derived from the same table the lexicon is built from, and three tests hold the invariant in both directions: everything offered to extraction resolves at query time, and everything resolvable is offered unless explicitly retired. Only canonical keys cross over. Surface forms stay read-side, deliberately: they never enter an extraction prompt, where they would cost tokens on every call and invite the extractor to choose inconsistently between buy, buys and purchased, which is the opposite of the consolidation the vocabulary exists to produce. RetiredRelations is empty but present, because retiring a relation must stop new writes without making facts already stored under it unreachable - a graph does not rewrite itself when a vocabulary changes. It exists so that removing a key later is a recorded decision rather than another silent divergence. Deliberate behaviour change: the vocabulary grows 46 to 58 entries and is now offered in canonical space form rather than was_born. Both spellings fold to the identical predicate_key so nothing about what reaches the graph changes, and the natural phrase is the better thing to put in front of a language model. The vocabulary fingerprint added earlier today records the change in every run report. It takes effect only on the next cold build, since the vocabulary is consumed at extraction time. The prompt test that asserted the was_born spelling characterized the old format rather than an invariant; it now asserts that every offered relation appears in the prompt.

The prepared-pair report recorded how many items each category contributed but never how large the resulting context was, so no arm could be compared to another on cost. That gap matters now. The recorded band gives Structured 673 tokens against Hybrid's 2,143, and that ratio is the load-bearing premise of the tier ladder - the light rung exists because structured-only was cheap. Those figures predate predicate expansion, which adds up to 100 further facts, so the premise is probably false and nothing in the artifact could settle it. Measures the assembled answer prompt, which is the arm's real cost rather than a proxy for it, and reports mean and max per arm. Deliberately an estimate at four characters per token, and named Estimate rather than Tokens: the question is whether one arm costs several times another, and a ratio survives a consistent approximation. Implying an exact count invites comparison against a provider's billing, which this is not. An existing adapter equivalence test failed because it froze the whole telemetry shape. The two new fields are real measurements of the run rather than fixed expectations, so they are excluded from the frozen shape and asserted on their own terms instead.

JSON because it is diffable in review, is what the unifier emits, and can carry per-relation source and licence provenance that a C# array cannot express - this ships in a package and draws on schema.org and Wikidata. Embedded rather than on disk because a file dependency in a library is a deployment hazard and a startup I/O failure mode. Sources, with a README beside the data recording all of it: schema.org Action hierarchy (CC BY-SA 3.0) seeds the event family, 36 relations including the whole trade and transfer group. Wikidata property aliases via SPARQL skos:altLabel (CC0) seed the state family, which schema.org cannot supply because Actions model events and 44.7% of this corpus is states - `is` alone is 26% of all facts and has no Action at all. Eighteen relations remain hand-authored because no surveyed source provides domestic life, including assembled and fixed. FewRel was surveyed and contributed almost nothing: 744 relations produced 28 apparent matches of which all but one are spurious substring collisions - has pet, has melody, has grammatical mood, studied by matching died. The single genuine match is P2283 uses. Recorded as a negative result rather than quietly dropped, since the original plan assumed these corpora would carry the work. Wiki-NRE, Google-RE and NYT10 are excluded for having no licence, REBEL for a self-contradictory README, TACRED for being paid. Provenance is earned rather than asserted: a wikidata source is recorded only where that property actually contributed a form. An early build claimed wikidata provenance while containing none of its data because a path error was silently swallowed, so the generator now fails closed. Invariants are enforced by tests so a malformed table fails CI instead of throwing inside a consumer's process at first use: provenance and family present, keys in stored predicate_key form, no surface form claimed twice or colliding with another key, opposing pairs intact, and both sides of the one table agreeing. Unit 3,734 -> 3,742.

Twenty-four of the fifty resolved to nothing. Its strongest finding is a design defect: surfaceForms carries two jobs at once. It decides what a question retrieves AND lists the stored predicate keys expansion fetches. The copulas need the second job and are actively harmful in the first - was, had and have appear in nearly every question a person asks, and each one expanded `is`, which is 26% of the measured graph, exhausting the shared budget before any correct relation was reached. Deleting them was not an option because facts really are stored under them. They are now storedOnly: still fetched by expansion, never a trigger. Removed twenty-nine mined aliases the reviewer verified as false matches, with worked examples: "Where is the location of the restaurant?" resolved to works at; "Did I ever buy a house?" resolved to lives in; "Set up a meeting" resolved to assembled; "Who is my business partner?" resolved to married. These came from Wikidata and are exactly the precision risk that argued for a reviewed tier in the first place. Added the missing inflections it found, each verified unreachable: donate, order, ask for, member of, join, spouse, go to, been to, study, mend, pass away, relocate to, participate in, and the bare update/increase/decrease forms. Retired two duplicate keys. finished and completed shared a schema.org source and a meaning with disjoint forms, so "Did I finish the Spanish course?" could never reach facts stored as completed; welcomed is one of the five phrasings of a birth that motivated this work. Both merged into their survivor, and the retire mechanism now works the way it was designed to: the retired name lives on as a surface form of the relation it merged into, so old graphs stay readable through the survivor rather than through a key that no longer exists. Added twenty-three relations for domains that were simply absent - paid, costs, booked, lost, broke, stopped, called, sent, told, played, ate, cooked, installed, applied for, stayed at, feels, allergic to, diagnosed with, owes, listened to, decided, returned from, rented out. Fifty-eight keys of a ~400 ceiling were in use while whole domains had no representation. The write-side invariant is refined rather than weakened: everything offered to extraction resolves at query time, unless it is an explicitly enumerated query stop form. The exception is listed in the artifact, not inferred by the test. 79 relations, 419 surface forms. Unit 3,742 -> 3,750; LongMemEval 163; Release 0/0.

The family field was internally inconsistent, marking durable dispositions (likes, prefers, wants, avoids, uses, owns, knows) as events while the equally stative requires was a state. A field a reviewer cannot trust is worse than no field, so the classification is corrected and a test pins the cases that were wrong. 52 event, 27 state. The inflection gate is the mechanical version of what the reviewer did by hand. The stemmer strips suffixes but never adds them, so a listed form's siblings can land on a different relation by accident. The test walks every stored form, tries the -s, -ing and -ed inflections, and fails if any resolves to a relation other than its own. A miss is fine - not every inflection is real English - but landing on a neighbour is a wrong retrieval in production. Unit 3,750 -> 3,752.

The reviewer built a reimplementation of the matcher and ran a 121-question battery plus 32 over-fire traps rather than reading the file, then verified its own patch: 29/29 failing questions fixed, 11/11 traps silenced, zero ambiguous forms. Its headline finding is a systematic coverage hole rather than any single bad entry. For 8 of 21 multi-word relations the bare verb resolved to nothing, and that is the commonest question shape a personal assistant sees - "Where do I work?", "Where do my parents live?", "Where did I travel?", "Where am I staying?" all retrieved nothing at all. Four one-word additions repair them. The worst single defect was not a miss but a wrong answer: "Did I give up coffee?" resolved to `gave`, the gifts and donations relation, a near-opposite. The bigram now wins by longest-phrase-first. Removed the high-frequency unigrams that violated the file's own precision-first doctrine, each verified pulling a whole irrelevant relation into a fixed budget: `book`/`books` on booked turned every reading question into a reservations lookup, `make`/`made` on created swallowed "how much money did I make" and "did I make dinner", `wed` on married fired on "Wed 6pm dentist", and `rate`/`rates` on rated fired on heart rate and interest rate. Removals are applied to the whole stem closure, because deleting a plural is a no-op when the stemmer regenerates the singular. The verb senses are recovered at full precision by bigrams. Added 16 relations for domains that had none: read, earned, works on, exercised, slept, weighs, prescribed, drank, subscribed to, renewed, cleaned, threw away, promised, hired, invested in, signed. `earned` matters disproportionately - the money family had only outflow, making it the one opposing pair with a missing side. Also corrected a test of my own that the reviewer caught passing VACUOUSLY: asserting a retired name is absent from the canonical set is trivially true once demoted and proves nothing. It now asserts the real property, that the name resolves to a different live relation and that expanding that survivor actually fetches the retired key. The two retirement mechanisms - demotion and flagging - are now documented, since only one was in use and the other looked like dead code. 95 relations, 508 surface forms, 0 ambiguous.

It found a different defect class than the previous round, so the loop continues rather than stopping on a single flat reading. Thirteen bare verbs double as assistant boilerplate. "give me", "tell me", "do you know", "i need", "find me", "which phone plan" each expanded a whole relation into the fixed retrieval budget. Bare `plan` is the worst case because `planned` is the largest measured bucket at 839 facts, so a question about a phone plan could displace most of a budget. The instrument is move-to-storedOnly plus re-admission through a question-anchored phrase, not deletion: the key stays in the table so expansion still fetches facts written under it, and longest-phrase-first tries "do i work" before the suppressed bare "work". No code change was needed. Two guard phrases are included because without them the moves regress - "do i work" would otherwise swallow "work out". Removed gift and gifts from `gave`: nouns with no direction sitting on half of a declared opposing pair, so "What gifts did I receive?" fired `gave`. Both had to go together since one stems to the other. Six relations added for domains with no coverage: took, arrived, expires, saved, injured, promoted. Bare `take` deliberately excluded - it fires on "take a look". Separately, a correction to my own earlier work. PARAREL and Rel2Text were fetched, licence-checked and analysed, but never actually merged: the generator meant to do it died on a syntax error and the review loop continued without noticing. They are merged now - 24 and 21 forms across 4 and 7 relations - with the merge refusing to run at all if a source file is absent, rather than quietly producing an artifact that claims provenance it does not contain. The README shipped in the package was materially wrong after four rounds of edits: 58 relations against an actual 101, 18 hand-authored against 60, and "retired: empty today" while two relations were retired. It is now generated from the artifact rather than maintained by hand. 101 relations, 619 surface forms, 32 stop forms, 0 ambiguous. Unit 3,752; LongMemEval 163; Release 0/0.

Resolve checked the stop list against the raw normalized form, then stemmed and looked up the result WITHOUT re-checking it, so a suppressed bare verb was handed straight back through its own inflections: "Let me know if that works" resolved works at, pulling 28 predicate keys into a 100-fact budget. This silently weakened every suppression decision in the vocabulary, including any made later, which is why it is worth one line rather than more per-form edits. The existing inflection test could not catch it. That test flags an inflection landing on a DIFFERENT relation, and work -> works at is the same relation. Also removed five sibling phrases that re-admitted the very verb they were meant to suppress (give the, give my, order the, order a, order from), five Wikidata phrases longer than the four-word match window and therefore unreachable from any question, and the verified over-fires like, text, played in the, expired at and works for. One judgement call against the reviewer's preference: bare "working" is suppressed rather than listed. It is boilerplate more often than memory - "is it working?" - and works at costs 28 keys of a shared budget. "worked", "working at" and "working for" carry the real questions. This is the fourth and final round. Two consecutive rounds scored 7.0 with zero delta, so the pre-registered plateau condition fired and the loop stops at 7 rather than the 9 target. The rubric was not revised to reach it: doing so is precisely the failure mode that guard exists to prevent. The plateau is informative rather than a dead end. Rounds 3 and 4 each found a different defect class, so the artifact improved materially while the score stood still, and the score is bounded by precision: 25 of 40 boilerplate probes still fire. Per-form suppression does not scale to the imperative-instruction shape, and the structural answer - a first-person gate requiring i/my/did/do inside the match window - is a change to the matcher, not to the data. 101 relations, 620 surface forms, 38 stop forms, 0 ambiguous. Unit 3,757; LongMemEval 163; Release 0/0.

"Create a summary", "Save the file", "Read the contents" all fire a relation, and none of those verbs can be deleted because each is a legitimate memory relation. Roughly a quarter of ordinary assistant traffic was expanding a whole relation into a fixed retrieval budget on that shape alone. It is a property of the sentence, not of any single verb, which is why four rounds of data editing never moved it. The first attempt was a first-person gate, as the review suggested. Measuring it against the benchmark before trusting it showed it would block "How many babies were born to friends and family members" - a question with no first-person marker anywhere, and the single question predicate expansion is proven to flip in a controlled A/B. That gate would have traded away the only measured win this track has. The discriminator is mood, not person. An imperative is a bare verb with no subject, so the test is that the sentence opens on a relation verb while carrying neither an interrogative nor a first-person marker. Verified: zero of the ten benchmark questions are blocked. Also confirms the source question with a third measurement. All 1,517 Rel2Text relations and all 39 PARAREL relations were tested for overlap by exact label match, not sampled: the additional yield is five surface forms, of which most are encyclopedic noise. The sources are not under-mined, they are exhausted for this domain, which is why 60 of 101 keys are hand-authored. Unit 3,757 -> 3,769; LongMemEval 163; Release 0/0.

Retiring `welcomed` into `was born` was reasoned entirely from the read side - a question saying "welcomed" should find births - which is true and irrelevant to what the extractor stores. Removing it from the offered vocabulary took `welcomed` from 7 facts to 0, births scattered, and 2e6d26dc regressed from correct in five straight runs to incorrect in both runs on the rebuilt graph. Retiring a relation is a WRITE-side change. Demotion is only safe when the survivor genuinely absorbs the extraction, and here it did not. Also declares expansionExempt explicitly. `has` absorbed 518 facts in that build while every one of its trigger forms was stop-listed, so those facts could never be expanded. The first version of this invariant asserted no such relation may exist; measurement corrected it, because they are still reachable by top-K similarity - they are un-expandable, not unreachable - and expanding a copula wholesale would flood a fixed budget with near-meaningless facts. The rule is therefore that every one must be a declared exemption carrying a reason, which makes the asymmetry a recorded decision rather than an accident of storedOnly. The J1.6 result itself was a trade, not a regression: gpt4_15e38248, the furniture question that failed all eleven runs on the old graph, is now correct in both runs on the new one, because `assembled` finally exists as a stored predicate. No read-side work could have done that. 102 relations. Unit 3,772 -> 3,774; Release 0/0.

Root-caused from the formatter's own source rather than guessed. It pads an unanswered user turn with "I understand." in TWO places: at the end of a session, and mid-session whenever two user turns are consecutive, because the pending user is flushed when the next user turn arrives. Our alignment accepted only the trailing case, so any question containing back-to-back user turns failed outright. The discriminator is exact: all ten questions in the fixed sample have zero consecutive-user pairs; the failing question has four. Dataset-wide it affects 8 of 500 questions, which is precisely why the fixed ten never hit it - the same shape as BUG-M1, which hid in 4 of 500. Three other candidate causes were ruled out by measurement rather than argument: duplicate turns, assistant-first sessions and odd session lengths all occur in questions that align fine, one of them with sixteen duplicates. This is not a relaxed guard. A mid-session pad has exactly the same provenance as a trailing one - synthetic formatter output following a user turn - and is recorded as synthetic padding either way. The check now matches the formatter's real contract instead of a subset of it, and validates the pad against the turn it actually follows rather than against the end of the session. Verified at zero provider calls: 30 questions preflight at 364 calls / 1,413 sessions, 50 at 614 / 2,376, 100 at 1,235 / 4,782. The fixed-ten control is byte-identical at 121 calls / 474 sessions, so nothing about the existing baseline moves. LongMemEval 163.

This answers that without spending a paid run: read-only, no Azure credentials, one container. Reports index health BEFORE any count, because K1 established that a FAILED or absent task_embedding_idx produces the identical symptom to an empty corpus, and this repository has already shipped a fix for indexes left FAILED. Interpreting a zero without checking the index first would repeat that mistake. Also counts ReasoningStep, not only ReasoningTrace, because K3 found upstream searches at step granularity and calls it the more useful cut - measuring only traces would answer the question upstream considers secondary. Reports a zero trace count as a real result about the fixture rather than the code: nothing in the LongMemEval ingestion path writes traces, so the surface may simply have nothing to find on this corpus. Not yet executed. The 50-question band is mid-run and holds the Release output lock, and starting a second Neo4j against 2,376 source sessions risks the OOM signature that killed six earlier runs. Verified to compile via Debug; it runs once the band completes.

Top-K is a relevance cutoff and gives no completeness guarantee, so a "how many" question is unanswerable from it: miss one of five matching facts and the count is four, with nothing signalling the loss. Routed rather than defaulted on, because expansion roughly triples the retrieved context - 649 to 2,027 tokens measured - and only helps the questions that need completeness. Both failures this track spent the most effort on open with "how many", which is what makes a lexical route sufficient here instead of a model call. A note on the bug this took to find. The pattern was written through a shell heredoc into Python, which collapsed the intended \b into the escape it spells: a literal backspace character. The regex could never match, and every tool used to inspect it - grep, sed, the editor - renders a backspace invisibly, so the line read as correct in all of them. A clean rebuild, a culture-invariance fix and a test-project wipe were all spent on the wrong hypothesis before cat -A showed the byte. The same escaping also silently no-op'd the CultureInvariant edit, which is the second time this session a patch script reported success while changing nothing. CultureInvariant is now set regardless: IgnoreCase alone is culture-sensitive, and this repository already fixed one class of culture-dependent formatting. Unit 3,774 -> 3,785.

K1 concluded the likely reason was that it contributes one opaque prose string where every other surface contributes typed items the evidence accounting can attribute - so it could not be scored, and a surface that cannot be scored gets budgeted at zero and forgotten. The information was never missing. GraphRagContextItem already carries Text, Score, SourceNodeIds and Metadata. The assembler joined the text and discarded the rest, one line before it could be used. This retains the items alongside the joined string. GraphRagContext is byte-identical, and a test pins that: attribution must be additive, or it becomes a retrieval change masquerading as instrumentation. The item list is empty rather than null when GraphRAG is off, so a caller counting contributions needs no null check to tell "disabled" from "returned nothing". This reframes K4 from "give the harness attribution it cannot have" to "stop throwing away the attribution that already exists", and unblocks K6 measuring the surface at a non-zero budget for the first time.

Both surfaces have carried a budget of zero in every quality measurement, so "zero" had never been checked to mean zero. It matters more than it sounds. Neo4jGraphRagContextSource deliberately treats a TopK of 0 as "use the configured default" rather than "return nothing", pinned by its own test. The composed system is safe only because the assembler skips the call entirely rather than passing zero through - a property that until now was held by a code comment describing it as a quirk being sidestepped. Four tests now hold it: a zero budget reaches the source as no call at all, and a non-zero budget passes through verbatim, for both traces and GraphRAG. All four passed on first run, which is the honest result for a verification task. Selection was already covered: the policy never excludes the GraphRag category and adds ReasoningTraces for precedent and task-oriented queries. So both surfaces ARE selected by the policy - their zero budget came from the benchmark adapter, not from the recall decision. Recorded and NOT changed: a direct consumer of IGraphRagContextSource asking for zero items still receives the configured default. That is deliberate, tested, and on a SemVer-locked public interface, so it is a finding to decide on rather than something to alter silently mid-session. Unit 3,788 -> 3,792.

Two specifics made this worth checking rather than assuming. IMemoryIsolationPolicy is an OPTIONAL dependency on this source, so a composition registering the Neo4j package without Core has no policy at all. And an unscoped owner produces a query that is byte-for-byte the legacy unscoped one, which returns every owner's nodes - the same class Phase 1.3 already fixed for predicate expansion. The result is reassuring and now held by tests rather than by reading. The requesting owner reaches the retriever, one owner id is never substituted for another, StrictMultiTenant throws on an unscoped read instead of quietly widening to every owner, and - the part most worth pinning - that throw is not swallowed by the source's best-effort error handling, which deliberately converts genuine retrieval failures into empty results. An isolation violation laundered through that path would be indistinguishable from a legitimate miss. Without a policy the raw UserId is still passed through, so scoping itself survives; what is unavailable in that composition is the StrictMultiTenant guard, which matches the source's own documentation. All four passed first run. That is the honest outcome for a verification task and is reported as such. Unit 3,792 -> 3,796.

Giving it a budget required fixing three things first, two of which are product defects rather than harness gaps. K6 result, 30 questions over the pinned base against J5.2's frozen graph: 132 items returned across 29/30 questions, 132 of them naming a fact the structured surface had already retrieved -- 100%, zero exceptions -- for +70 tokens per question and the same verdict on all thirty questions. Pointed at the memory layer's own fact index, GraphRAG re-fetches; it does not add. That says nothing about the separate-knowledge-graph setting the surface was designed for, which this corpus does not have. The first run reported zero items and would have read as a damning result about the surface. It was a harness defect: BlendMode = MemoryOnly means "GraphRAG suppressed even when enabled" and is checked before the budget. BlendModeFor and GraphRagWiringTests now pin all three preconditions, so the next zero is evidence about the surface rather than the wiring. Two product defects fell out of the wiring, both pinned by tests: K9: MemoryOptions is an init-only record, so the Action the public registration API hands you cannot set any of its properties. The only shape that compiles -- `options = options with { ... }`, which the BlendedAgent sample ships -- rebinds a local and is discarded. The flagship GraphRAG sample runs with GraphRAG off, and no record-backed option (MaxFacts, BlendMode, decay, ranking, budgets) is reachable this way. K10: no memory-native node kind has a `text` or `content` property, so GraphRAG's default projection falls through to serialising the whole node, embedding vector included, straight into the prompt. Also establishes, via a read-only probe, that the reasoning-trace half of K6 is untestable here: 0 ReasoningTrace nodes with the index ONLINE. That is the absence of a test, not a null result about the surface. Full unit suites green: 3802 core + 173 harness.

AddAgentMemoryCore and AddNeo4jAgentMemory take an Action and hand it to .Configure(), which mutates one instance in place. But MemoryOptions is a record whose properties are all init-only, so the lambda cannot assign them -- `options.EnableGraphRag = true` is CS8852. The only shape that compiles is `options = options with { ... }`, which rebinds the parameter local and is discarded on return. That is what the BlendedAgent sample shipped, in Program.cs and its README. It compiled, it ran, and it left GraphRAG off in the repository's flagship GraphRAG sample. The reach is wider than one flag: no record-backed option was settable this way -- MaxFacts, MaxEntities, BlendMode, MaxGraphRagItems, decay, ranking, every context budget. It survived because every working call site in the repo builds options with an object initializer inside Options.Create(...) -- tests, HermeticProfile, PerfScenarios -- so the suite exercised a path no consumer uses. Isolation works only because #100 made MemoryIsolationOptions a mutable class; that lesson was applied to one option and never generalized. Fix: additive overloads taking the instance directly, which is how every working call site already builds options. The supplied instance is run through the same validators the lambda path registers -- checked, not trusted -- so this is not a hole through the validation chain. Chosen over changing init to set, which would alter the setter signature of a public type on a SemVer-locked surface and break binary compatibility. One narrow source-level cost, documented on the overload: an untyped null as the first argument is now ambiguous and needs an explicit cast. That shape occurs once in the solution, in a null-guard test. Tests mutation-checked: both new assertions fail against an implementation that ignores the instance or skips validation. 3805 core + 173 harness unit tests green.

It had never been re-run, and it was a Python replica of the lexicon rather than the lexicon. Both are fixed: the gate is now code, scored through the shipped MemoryRelationLexicon, with tests proving it can fail. Predicted 100% in both slices. Wrong twice, and both errors were in the gate. First, it scored STORAGE coverage with Resolve, the QUERY-side method, which rejects stop forms by design so a question mentioning "is" cannot expand into the whole graph. That counted `has` (1,583 facts) and `is` (1,118) as unknown vocabulary -- 18% of the graph misreported, reading the gate down to 81.5%. Adding IsKnownStoredForm applies the same normalisation and stemming without the query-side suppression. The stop forms were NOT made resolvable; that would defeat the suppression they exist for. Second, the rebanding that followed the original 15.4-point skew failure had silently replaced gate 1's relative criterion -- held-out within 5 points of build, "proving the artifact generalises rather than fitting the predicates we happened to look at" -- with an absolute 100%. That is self-defeating: any absolute bar can be met by adding the observed predicates to the vocabulary, held-out ones included, which is exactly what holding them out detects. Banding was the right fix for skew; relative-to-absolute was not. Restored to banded AND relative; absolute coverage is reported, never gated. Said plainly, since this moves a FAIL to a PASS: under the literal "100%" wording the gate fails at 90.8/93.8. Under the criterion gate 1 was written to express it passes, with held-out (93.8%) above build (90.8%) -- the vocabulary generalising slightly better to predicates it was not built against. 7 genuine gaps retained, not netted off: helped, helps, provided, noticed, heard, provides, and practiced (held out). 108 facts, 0.7% of the graph. Adding them is sequenced as J1.5c behind a cold rebuild, because J1.6 showed a vocabulary edit moves extraction unpredictably. 3805 core + 179 harness unit tests green.

J1.5b found seven high-frequency predicates the 101-entry vocabulary did not know. Four canonical relations added -- helped, provided, noticed, heard, with inflections and non-colliding synonyms -- taking the table to 106. `practiced` is deliberately excluded: it is a held-out miss, and adding it would fit the vocabulary to the slice that exists to test it. Predicted that adding the six build-slice misses would take build coverage to 100% while held-out stayed at 93.8%, failing the gate by 6.25 points as it detected fitting-to-observed. Confirmed exactly. That failure exposed something worse than the vocabulary gap. The bound band holds ~16 held-out predicates, so one miss is 6.25 points -- already past the 5-point tolerance. At this slice size the gate cannot express "slightly worse"; it is binary and hostage to which predicates the split drew. Same class of defect as the original 15.4-point skew failure: a threshold finer than the statistic's resolution. Fixed by measuring the distribution rather than one draw. Across five seeds the gate passes 4/5 with held-out coverage at 100% on every passing split. The single failure is seed 42 -- the split whose build slice authored the edit, and therefore not a held-out evaluation of it. Multi-seed support lives in the tool, not in a planning document, because a protocol recorded only in prose is one nobody runs. The tempting wrong move is recorded because it was tempting: widening the tolerance to max(5 points, one predicate) lands at exactly 6.25 and flips the seed-42 FAIL to a PASS at the boundary. That is a threshold chosen to fit the result, and it was rejected. These entries are coverage-verified but extraction-unmeasured. J1.6 is the standing proof that a vocabulary edit moves extraction unpredictably, so J1.5d holds a cold rebuild to measure it. 3805 core + 179 harness unit tests green; all 93 vocabulary gates pass.

The accounting guard was right to fail closed; the reason it had something to reject was a defect one layer down. LlmMultiSessionUnifiedMemoryExtractor caught `Exception` and split the batch whenever it held more than one session. Splitting is a genuine remedy when the batch itself is the problem -- too many input tokens, an incomplete acknowledgement, an unusable source-session key, an unparseable response -- and every one of those arrives as a FormatException, BatchValidationException deriving from it. A provider transport failure is not that. Halving the batch re-sends the same request shape to the same endpoint that just failed, so the split neither diagnoses nor fixes anything, and it doubles the call count for that question. Transport failures belong to the configured retry policy. The catch is now FormatException, which is exactly the set of shape-caused failures. Also surfaces the provider status code in the accounting-mismatch message. The old message named the exception type but not the status, which is the difference between "we are being rate limited", "the request was malformed" and "the service failed" -- three problems with opposite responses. Status codes carry no content, which was the reason the detail was omitted. Tests written red-first: both failed against the old behaviour on call counts, proving they detect the split. The control test asserts that unparseable responses still split, so the fix cannot have removed the useful half. The exact split call count is deliberately not asserted -- that is recursion depth, not the property under test. 3807 core + 179 harness unit tests green.

Checking it found no such policy on that path. LlmExtractionOptions.MaxRetries is set by the harness, validated at registration, and honoured by LlmExtractionRunner -- but only by re-prompting on unparseable JSON. The runner's GetResponseAsync call sits outside any try/catch, so a transport exception propagates on the first attempt. Nothing else retries; the call meter counts retries without performing any. So a 614-call preparation had no protection against a single transient, which is how the first n=50 attempt died at question 20 after 37 minutes. The splitter was the only thing resembling a retry for transports, and a bad one: it re-sent to the endpoint that had just failed. Removing it removed a misleading recovery, not a working one -- which is what the corrected comment now says. A real transport retry is not a one-line addition: the prepared-pair guard requires exactly BatchCount calls and zero failures, so any retry trips the same guard that the split tripped. The refinement is recorded in the plan -- the invariant should be "each batch produced exactly one SUCCESSFUL call and every retry is recorded", not "no provider error ever occurred", which no 614-call network run can promise. Deferred while the n=50 run is in flight so its result is produced under the contract that was recorded.

There was no transport retry anywhere in the extraction path: LlmExtractionRunner honoured MaxRetries only by re-prompting on unparseable JSON, and its provider call sat outside any catch. At that call volume the absence was not a robustness gap, it was a hard blocker on the measurement. Three changes, together, because any one alone just moves the failure: 1. LlmExtractionRunner retries transport failures with backoff, bounded by MaxRetries. FormatException is not retried -- it is caused by the request's own shape, so re-sending it unchanged cannot help, and the parse loop and batch splitter already handle that family. Cancellation is never retried: doing so would make the preparation watchdog's timeout unenforceable. 2. The prepared-pair accounting guard now checks that every batch produced exactly one SUCCESSFUL unified-batch call, rather than that no provider error ever occurred -- which no 614-call network run can promise. This is simpler than the design anticipated: a recovered retry is exactly one extra call plus one failure, so calls-minus-failures recovers the successful count with no new declaration mechanism. Nothing is loosened; an unrecovered failure still throws before the check and a spurious extra call still trips it. 3. The top-level handler printed only exception.Message, so a stage wrapper reported "LongMemEval batched extraction stage failed." and a 26-minute run died with no cause attached. It now prints the whole inner-exception chain, types and messages, no stack traces. Tests red-first: the retry tests failed on call counts against the old behaviour, and the persistent-failure and cancellation cases pin that the retry is bounded and never swallows a cancellation. 3810 core + 179 harness unit tests green.

Three consecutive 15-40 minute preparations have now been ended by this guard, none of them for a real defect. The guard demanded exactly the planned number of provider calls and zero failures -- that is, it demanded that nothing ever went wrong. That is incompatible with the recovery paths the extractor ships: a parse retry re-prompts, a split re-sends the halves, and both legitimately add calls. Correctness was never this guard's job and still is not. The session-set comparison beside it proves every planned source session was persisted, in chronological order, all succeeded, and it is untouched. This is a cost guard, so the invariant it should express is "no unaccounted work": at least the planned calls happened, nothing of an unexpected purpose ran, and any excess coincides with a recorded split or retry. Refining a guard is only defensible if it still catches what it was for, so the decision is extracted as a pure function and tested at its boundaries. The load-bearing case -- excess calls with no recorded split and no recorded retry -- is still rejected, as is under-running, an unexpected call purpose even when recovery is recorded, and missing split diagnostics, which fail closed rather than reading as innocent. The pre-existing FailsClosedOnAnUnplannedProviderCall test still passes on behaviour; only its message assertion moved, and its comment now records why. 3810 core + 186 harness unit tests green.

The dump named the cause precisely: first_failure_status=400, slowest_input=59043 tokens. HTTP 400 is Bad Request -- the deployment was rejecting oversized batches outright. This indicts the previous two commits, together. The transport retry treated everything that was not a FormatException as transient, so it re-sent requests the provider had already rejected as malformed, three times each. And narrowing the splitter to FormatException meant an oversized-input 400 no longer split either. Between them, oversized batches became unrecoverable and expensive: the one path that could have fixed them declined, and the other paid for the same rejection repeatedly. Both classifications are now explicit and tested: - Retry 408, 429 and 5xx, plus failures carrying no status at all, which never reached the service. Everything else is permanent; re-sending an identical request cannot change a 400. - Split on FormatException OR a permanent 4xx. An oversized request IS a batch-shape problem, which is exactly what splitting is for. 408 and 429 are excluded deliberately -- answering a rate limit by sending more requests is the wrong direction. The status is read reflectively, covering ClientResultException.Status and HttpRequestException.StatusCode, so this library needs no package dependency to classify an error. Also lowers the harness to --max-input-tokens 40000 from the 100,000 default, which was never a real limit for this deployment. That removes the trigger; the two fixes above handle it if it recurs. 3818 core + 186 harness unit tests green.

Every other question type is within one question, and knowledge-update and single-session-user are identical. It could not say why. The losses and wins are indistinguishable by volume -- 61.8 mean facts on the losses against 59.0 on the wins, 1,841 tokens against 1,768 -- so Structured is not retrieving less. And GoldEvidenceCoverage is null in every prepared-pair report, because the existing probe sits inside `if (!PreparedMemory)` and therefore runs only during preparation, never on the path that produces the measurements. That probe also answers a different question: it asks whether anything was LEARNED from the gold sessions. This adds the retrieval-side half -- whether the gold evidence reached the context -- by intersecting the retrieved facts' SourceMessageIds with the question's gold source messages. Facts carry that provenance and the Neo4j repository populates it on read, so no new query is needed. Together the two separate three failures that look identical in a score: the evidence was never extracted, it was extracted but not retrieved, or it was retrieved and the reader still got it wrong. Only the middle one is a retrieval problem, and only the first is an extraction problem, so this is what decides where the next effort goes. Returns null rather than zero when a question has no gold messages: zero coverage of nothing is not a miss and must not be averaged in as one. 3818 core + 191 harness unit tests green.

Those need opposite responses: a missing vocabulary entry, versus a retrieval or reading problem. The distinction is not theoretical. Checking the four multi-session questions Structured loses at n=50 against the shipped lexicon by hand found two blocked at the query side before any retrieval happens, for opposite reasons: service/serviced/servicing is absent from the table entirely, and `has` is a deliberate query stop form that must not expand because it would pull in the whole graph. Both failed with expansion enabled and nothing to expand, and both looked exactly like an ordinary retrieval miss in the report. MemoryContext now carries ResolvedQueryRelations, and the harness reports it per question, so that state is visible in every future run instead of requiring the lexicon to be consulted by hand afterwards. Also retracts, in the plan, a conclusion drawn earlier in this session. The retrieved-gold-coverage metric added a few commits ago saturates: 30 of 50 questions land on exactly 6/7 because one gold message per question systematically yields no fact. Two group means were compared without checking the distribution behind them, and a saturated metric produces near-equal means for any two groups. The claim that the multi-session deficit is not a retrieval failure does not follow and is withdrawn; the metric cannot answer that question. Relation completeness, not message coverage, is what could. 3821 core + 191 harness unit tests green.

Reporting ResolvedQueryRelations localised the whole Structured/Hybrid gap: on the 40 questions where predicate expansion resolves at least one relation Structured scores 87.5% against Hybrid's 90.0%, at 2.5x less context. On the 10 where it resolves nothing, Structured collapses to 50.0% while Hybrid holds at 80.0%. Those ten questions carry the arm gap. Reading the ten showed what they needed. Four relations were absent from the table entirely -- tried, wakes, led, commutes -- and each maps to a question in the bucket: how many Korean restaurants have I tried, what time do I wake up, how many women on the team led by my former manager, how long is my daily commute. Two more were surface-form gaps on relations already present, and the ambiguity gate caught both attempts to add them as new canonicals: `participate in` already belongs to `attended` and only the bare `participated` was missing, and `stay` already belongs to `stayed at`. Failing closed there is exactly what that gate is for. Not every blocked question is fixable this way, and conflating them would be a mistake. `has` is a deliberate query stop form -- expanding it would pull in the whole graph on any question containing "is" -- so aggregating over a stop-formed relation is a missing capability, not a missing word. One question is a conversational back-reference with no relation at all. This is a query-side change only: the graph is untouched, so it is measurable by reuse on the frozen n=50 base with no rebuild and no extraction spend, and the build-variance caveat does not apply. Prediction locked before running: the bucket shrinks from 10 to about 4-5, and Structured moves +2 to +4 questions. 3821 core + 191 harness unit tests green; all 96 vocabulary gates pass.

The diagnostic added earlier captured the cause exactly: FailureKind=unparseable, RejectedToken="Judge". So this was never the judge being wrong. The judge produced a verdict; the parser could not read it. It stripped exactly two hardcoded prefixes -- "Judge said:" and "Judge outcome:" -- and required the next letter-token to be yes or no. A third "Judge...:" shape falls straight through. On one of the two runs the retry recovered the same question with a valid verdict, which is the clearest evidence available that the judgement was fine and the parsing was not. The fix is deliberately one-way: a leading label is only stripped when what follows is ACTUALLY a yes or no, so tolerance can never manufacture a verdict from a hedge. The label must also begin "judg" and sit within 32 characters, and only the first colon is considered, so a sentence that merely contains a colon cannot be mined. The first attempt was too permissive -- any short label -- and the guard test caught it: "maybe: yes" parsed as a verdict.

It is a deterministic Cypher count(), immune to answer-model and judge non-determinism, so if a change stops learning a relation the questions need, D drops and says so. Nothing else in this repository can see that: the deterministic fixture sits at 1.000 by construction with no headroom, and the LongMemEval channel carries sd 9.3 cold-build. That gap is why 44 register items that touch extraction cannot currently be accepted or rejected on evidence. Keeping D and N apart is what makes the metric diagnostic rather than merely another score. D = 0 with a non-empty key set means the relation was never extracted -- an extraction or vocabulary miss. N < D means it was extracted and retrieval left some behind -- a retrieval defect. A single ratio renders those identical, which is precisely how the saturated message-coverage metric misled this track once already. Also reports LimitBinding (D > MaxExpandedFacts), because completeness is arithmetically impossible when the graph holds more than the single shared LIMIT can return, and that is a budget fact rather than a retrieval defect. The probe mirrors FactQueries.SearchByCanonicalPredicates' WHERE clause exactly, minus ORDER BY/LIMIT, so the denominator counts precisely the rows expansion could have returned. It deliberately does NOT use coalesce(predicate_key, toLower(predicate)): a fact with a null predicate_key is invisible to expansion, so counting it would report an unreachable fact as a retrieval miss. The interface method is default-bodied, so none of the seven existing test stubs changed. Not-measured is an ABSENT field rather than an all-null object, matching ReadGoldCoverageAsync -- caught by an existing equivalence test that the first wiring broke. 3821 core + 215 harness unit tests green.

These are the three that survived. 1. CI would have been permanently red. AgentMemory.slnx lists the LongMemEval harness and its test project, and the harness carried an unconditional ProjectReference to a hardcoded absolute path in a separate repository. A verifier reproduced the exact failure: restore SUCCEEDS with only a warning, then Release build fails with 56 CS0246 errors, so the break lands after the step that would have made it obvious. Both ci.yml and release.yml run `dotnet build AgentMemory.slnx -c Release`. Fixed by consuming AgentEval as a package instead. AgentEval.Memory is IsPackable=false but ships bundled inside the AgentEval umbrella via ProjectReference PrivateAssets="all", and this harness uses only public API -- no InternalsVisibleTo grant exists -- so 0.18.0-beta from nuget.org satisfies it with no change to AgentEval and no new release. It also version-pins the evaluator, so a benchmark run stops depending on whatever sits in a sibling working tree. 2. Existing databases would have silently duplicated facts. Facts now MERGE on {subject_key, predicate_key, object_key, owner_key}; main has no *_key property anywhere, so on a pre-1.4 store those match nothing and every upsert of an existing fact creates a duplicate. BackfillCanonicalFactKeysAsync fixes it but runs only inside BootstrapAsync, and ISchemaBootstrapper is TryAddTransient -- the library never invokes it. Deliberately NOT fixed with a write-path scan or an auto-running hosted service: BootstrapAsync is the documented startup step, present in README, getting-started, agent-framework and every sample, so the backfill does run for anyone following the docs. Adding a per-write legacy scan would trade a contract violation for a permanent hot-path cost -- a new defect to fix an old one. Instead the state is made visible where an operator looks for it: schema-check now reports pending canonical keys and exits non-zero, and the CHANGELOG carries an explicit upgrade note. 3. A documented extension point crashed on upgrade. Neo4jMemoryPersistenceTransaction hard-cast the public INeo4jTransactionRunner to the later-added INeo4jAtomicTransactionRunner and threw. That runner is registered with TryAddSingleton precisely so hosts can substitute their own, and this type is registered with Replace, so it receives whatever they supplied: a substitution that was legal when written became a startup crash, with no compile-time signal. Atomicity is optional by design -- IMemoryPersistenceTransaction carries SupportsAtomicRollback and PersistenceStage already branches on it -- so a non-atomic runner now degrades to pass-through and reports false, rather than refusing to start or claiming a rollback guarantee it cannot keep. Pinned by four tests including the two failure modes that matter: it must not throw, and it must not report atomicity it does not have. Release build of the full solution: 0 warnings, 0 errors. 3825 core + 215 harness unit tests green.

It is not a regression, and the override was the wrong tool for it. The baseline predates the batched UNWIND upserts and batched embeddings that are on this branch. Re-recording shows what actually moved: PERF-W-05 queries 278 -> 8, tx.write 257 -> 1, embed.requests 7 -> 3 PERF-W-03 queries 88 -> 13, tx.write 48 -> 7, bytes_est -5,108 PERF-W-02 queries 43 -> 8, tx.write 18 -> 2, bytes_est -3,828 Two of the three write scenarios drop bytes as well as round trips. PERF-W-05 rises because 257 tiny writes become one batch: the payload concentrates into a single round trip rather than shrinking, which is the trade batching makes. Deliberately NOT resolved with the perf-counter-change label. That override exists for structural counters and the gate excludes bytes_est from it by an explicit `continue` before the override branch is reached -- payload is held to a harder standard on purpose. Forcing it would have meant defeating a guard rather than updating a stale baseline. The label has been removed from the PR. Only four counters increase anywhere: PERF-W-05 bytes_est as above, and PERF-R-04/07/08 bytes_est by 1,034 each (+0.7%, inside the 5% tolerance, with recall.chars +5 from the added ResolvedQueryRelations field). Four scenarios that exist on the branch but had no baseline entry are now recorded: PERF-W-06, W-07, W-08, W-09. Quality is unchanged -- every numeric metric identical, tolerance still 0. `perf baseline --update` dropped two non-numeric annotations, retrievalMeasurement "deterministic-plumbing" and semanticQualityClaim false, which exist precisely so that a 1.000 is not read as a quality claim. Both restored by hand; losing them silently would have been the more damaging half of this commit. Gate verified locally against the fresh run: perf gate: PASS.
