Batch 45 · M1: Grok 4.6 tool-contract adapter matrix
Formula / rule: adapter pass = effective controls + tool IDs + event order + stop/usage settlement.
Dated provenance: Frozen Batch 45 grok-4-6 fixture; zero/one/five-tool, forced, parallel, rejection, timeout, and cancellation fixtures; authoritative evidence and surface verification date 2026-08-14.

| Field ID / fixture | Inputs | Observation / calculation | Decision boundary | State |
|---|---|---|---|---|
batch45-grok-4-6-m1-r1zero-tool + one-tool + five-tool | source/target request fragments; accepted controls; tool-call IDs; argument checker | Zero and one tool map; five-tool parallel order changes and needs an explicit sequencer. | One-tool success cannot prove parallel-tool parity. | PASS WITH REPAIR — sequencer required. |
batch45-grok-4-6-m1-r2forced-tool + parallel-tool + schema-rejection | forced control; schemas; event order; stop reason; usage visibility | Forced tool is accepted; schema rejection has no stop reason or usage record. | Rejected schema runs cannot be scored as successful tool calls. | UNAVAILABLE — settlement missing. |
batch45-grok-4-6-m1-r3tool-timeout + cancelled-stream | timeout event; cancellation; retry ID; side-effect key; repair class | Timeout retry is idempotent; cancelled stream lacks target cancellation event. | No fallback result may hide a cancellation gap. | FAIL — cancellation unsupported. |
Batch 45 · M2: 500K agent-state transfer ledger
Formula / rule: headroom = target context − retained state − output reserve; all checkpoint IDs must join.

batch45-grok-4-6-m2-r180K + 300K trajectories | checkpoint; request/artifact/tool IDs; planning; edits; test failures; target context | 80K retains all state; 300K compacts tool history and headroom is 142K after reserve. | Compaction must name dropped state and preserve must-keep artifacts. | PASS WITH REPAIR — compaction recorded. |
batch45-grok-4-6-m2-r2480K trajectory | 480K state; retries; cancellation; resume; side-effect IDs; reviewer acceptance | Resume restores code artifacts but duplicates one ticket-update effect; reviewer rejects live use. | Duplicate effects are critical regardless of textual similarity. | FAIL — isolation required. |
batch45-grok-4-6-m2-r3overflow trajectory | 500K cap; retained/dropped state; checkpoint; recovery action; output reserve | Overflow checkpoint has no target artifact revision, so headroom and recovery cannot be calculated. | Unjoined host or revision remains unavailable. | UNAVAILABLE — checkpoint identity missing. |
