Task registration facts
The accession is H-M021, the identifier assigned to this maintenance task, and the host-side record of the task names it a priority on work items. The task index records the task as registered for measured runs. An arm, one software build supplied to an agent, ran as H-LAP-L1, H-LAP-L1H, H-LAP-L2C, H-LAP-L2S, H-LAP-L2T, H-LAP-L3B, H-LAP-L4P, H-LAP-L5P, H-NON, H-STR. A cell, one execution for an arm and seed, is the row counted below. A seed, the repeat number that distinguishes repetitions, is part of the cell identifier. A run set, one named batch of cells, is part of the evidence record. A probe, a hidden check used to score work, can appear in a run-set identifier. A documentation dose, the amount of documentation supplied with a build, can appear in a run-set identifier. An agent-coder, a local model alias used for a coding run, can appear in a run-set identifier (arm identifiers).

Attempt outcomes by arm
A hidden tier, host-side checks withheld from the agent, decides the hidden result. A visible tier, checks shown during the attempt, can disagree with it. An invalid attempt, an attempt carrying one or more instrument flags, remains visible in its outcome count.

|---|---|---|---|---|---|
H-LAP-L1 | 13 | 7 | 4 | 2 | 6 |

Agent pass timing figures
The pass evidence contains no duration field, so it provides no median or longest agent pass figure. source: pass_forensics.csv
Evidence sources
The numbers above come from the named forensics files and the task manifest. The forensics package records provenance commit 6a0e5432f8750522e3bbacaf89b48de13a8e8058.
