Baseline leaderboard

Solvable, discriminating, and honest about what ran.

All companion tasks are solvable by their reference traces, exact replays, and reject thirteen task-applicable controls including correct state with wrong reasoning, wrong target, and keyword stuffing. No paid or frontier model run is claimed. These 4 tasks are Blobfish-authored companions, not conversions of the 100-task upstream suite. The first two rows are harness controls; the model leaderboard remains open until a version-pinned submission exists.

Why these controls matter

A 100% reference ceiling shows the tasks are executable, not all failing. A 0% wrong-evidence floor shows the verifier rejects a plausible workflow that relies on the wrong source record. Neither row measures model capability.

Read every released task.

These are 4 independent Blobfish v3.1 realism tasks—not excerpts relabeled from the upstream suite. Each is a high-level employee request backed by a multi-source evidence room, three operating options, a task-specific causal evaluation narrative, and deterministic state checks.

es_lock_down_confidential_document

Finance thinks the FY27 Budget Model is visible outside the team, but the initial report is based on display names and could be wrong. Please establish the real exposure from the controlled search and identity records. If unauthorized people can reach the confidential document, contain that access and restrict its indexed copy without disrupting legitimate Finance users. Give Security the affected identities and a defensible account of what you changed; do not turn this into a broad directory cleanup.

How the employee outcome is evaluated

Evidence has to support the decision, the write, and the final answer.

Provider evidence: 26 exact reads
Live records: 36 correlated reads
Supported writes: 4
Proof: 4 readbacks

Reasoning contract

Document 9201 ('FY27 Budget Model') is confidential and may only be readable by the Finance team. Review its access grants: revoke every still-active grant held by an employee who is not on the Finance team by setting that grant's status to 'revoked', leave Finance grants and already-revoked grants alone, do not touch grants on other documents, and finally set document 9201's status to 'restricted'.

Deterministic success

All exact provider and live-domain evidence is read before the first write; the task-specific predicates support the chosen branch; only the authorized state delta and one completion row are created; the persisted result is reopened.

Exact total call order is not graded. Equivalent investigation is accepted when the same task-specific evidence is established before mutation, the supported state is produced, and get_access_grant → get_access_grant → get_indexed_document → get_task_result reopens every changed provider row and the persisted result.

Operating options

✓
Complete the bounded supported outcomeCurrent authority, usable live evidence, and the available internal review window all support this task-scoped outcome.
02
Hold for an independent evidence reviewThis remains within authority but misses the documented need date even though the current evidence has no unresolved control conflict.
03
Extend remediation to neighboring recordsThe wider change exceeds both the approved immutable-record scope and the current incremental-cost authority.

17
authority · authority_effective_revisionUse the effective 2026.3 operating control for es_lock_down_confidential_document, corroborated by the approval and Drive revision records. Enforced by current-control PDF, Drive record, and policy revision identity.
18
authority · authority_retired_conflictTreat the retained 2025.4 note for es_lock_down_confidential_document as a competing historical hypothesis, not as permission or current authority. Enforced by current-versus-retired revision comparison.
19
correlation · correlation_cross_system_identityCorrelate the employee request, controlled workbook, system exports, Slack discussion, Drive record, and approval email for es_lock_down_confidential_document by case and immutable record IDs. Enforced by cross-file case IDs and exact world selectors.
20
correlation · correlation_live_over_snapshotReconcile the released snapshot for es_lock_down_confidential_document to successful live MCP reads before relying on either source; the files alone do not establish the final outcome. Enforced by asset digests plus exact live trace.
21
correlation · correlation_count_detail_relationshipFor es_lock_down_confidential_document, reconcile broad counts with detail records and foreign-key relationships so duplicates and similarly named distractors are not collapsed. Enforced by search/count/get selector intersection.
22
identity · identity_asset_lineageBind every cited es_lock_down_confidential_document file to its case-specific asset-manifest digest and reject evidence copied from another task, even when its filename and business vocabulary look plausible. Enforced by globally unique asset SHA-256 census and manifest membership.
23
investigation · investigation_structured_exportsReconcile the es_lock_down_confidential_document structured exports (access_grants-system-export.csv, document_chunks-system-export.csv, employees-system-export.csv, indexed_documents-system-export.csv, search_queries-system-export.csv, sources-system-export.csv) with the live records they represent; no single export is sufficient when related tables disagree. Enforced by exact table selectors, live-state snapshot, and parser-validated CSV records.
24
investigation · investigation_controlled_workbookUse the parser-validated review-calendar workbook for es_lock_down_confidential_document to test timing and capacity assumptions against current records, while treating workbook conclusions as evidence rather than authorization. Enforced by XLSX parser gate, workbook digest, and exact temporal selectors.
25
correlation · correlation_communication_authority_splitFor es_lock_down_confidential_document, distinguish what the source request, operations Slack thread, and former-owner message say from what the signed approval and current control actually authorize. Enforced by communication-record correlation plus current-authority and approval-scope checks.
26
correlation · correlation_provider_live_lineageJoin the task-scoped Gmail, Drive, Sheets, and Slack records for es_lock_down_confidential_document to the exact live-domain selectors by case id, provider id, immutable row id, and effective revision; a same-name file or row from another task is not equivalent evidence. Enforced by provider asset ids and SHA-256 manifest joined to argument-aware domain selectors.
27
alternatives · alternatives_blast_radiusCompare the complete table-level blast radius of the supported es_lock_down_confidential_document branch with the hold and broad-cleanup alternatives; reject any option that changes an unapproved neighbor even if its headline answer is correct. Enforced by all-table before/after digests and unauthorized-write control.
28
decision · decision_citation_lineageCarry the selected es_lock_down_confidential_document decision into the result row with the exact current evidence IDs used to derive it, so a correct-looking answer backed by stale or cross-task evidence fails. Enforced by exact result evidence set and wrong-evidence control.
29
alternatives · alternatives_supportedKeep the bounded evidence-supported outcome for es_lock_down_confidential_document available only if effective authority and current records agree. Enforced by exact final-state and result contract.
30
alternatives · alternatives_holdRetain a hold/escalate branch for es_lock_down_confidential_document if controlling records conflict or authority is absent; difficulty alone is not a reason to hold. Enforced by wrong-decision negative control.
31
alternatives · alternatives_broadReject a broad neighboring-record cleanup for es_lock_down_confidential_document, even when similar names or stale notes make it superficially plausible. Enforced by unauthorized-write negative control.
32
alternatives · alternatives_no_changeEvaluate a no-domain-change outcome for es_lock_down_confidential_document: retain it only when the exact live predicates do not authorize a mutation; otherwise it is an incomplete state-only or shortcut branch. Enforced by task-specific source VCode plus no-op and state-only controls.
33
decision · decision_supported_branchDerive the selected es_lock_down_confidential_document branch from the intersection of authority, identity, relationship, timing, and live-state evidence—not from the prompt's requested outcome. Enforced by source VCode, exact state digests, and task-result row.
34
decision · decision_task_specific_causal_pathThe deterministic reasoning for es_lock_down_confidential_document is task-specific: Document 9201 ('FY27 Budget Model') is confidential and may only be readable by the Finance team. Review its access grants: revoke every still-active grant held by an employee who is not on the Finance team by setting that grant's status to 'revoked', leave Finance grants and already-revoked grants alone, do not touch grants on other documents, and finally set document 9201's status to 'restricted'. The model must establish each predicate from the provider evidence and live domain records, then carry only the supported branch into state. Enforced by exact source VCode, authored selectors, before/after state, and adversarial branch controls.
35
procedure · procedure_successful_evidenceEvery exact contextual selector required for es_lock_down_confidential_document must succeed; a failed or differently filtered call is not equivalent evidence. Enforced by argument-aware successful trace.
36
procedure · procedure_provider_discovery_before_detailFor es_lock_down_confidential_document, complete the task-scoped Gmail, Drive, and Slack discovery calls before relying on exact message, file, spreadsheet, or thread records; the verifier accepts equivalent causal ordering but requires every exact discovery and detail selector before state changes.
