Audit: align sample stages and complete trajectories

Dataset quality audit category: Sample alignment and completeness issues

The May 2026 dataset audit found 27 issues in this class:

• sample_alignment: 15
• trajectory_completeness: 8
• sample_representativeness: 4

Problem

Some datasets do not keep the same records across sample_raw.json, sample_std.json, and sample_sft.json, while others produce trajectories that end mid-action or combine multiple independent tasks into one trajectory. This makes examples hard to inspect, regenerate, and trust.

Examples

• android_in_the_wild: stage counts do not match; sample_raw.json has 3 records, but sample_std.json and sample_sft.json have 1.
• go-browse-wa: stage counts do not match; sample_raw.json has 100 records, but sample_std.json and sample_sft.json have 5.
• nemotron_terminal_corpus: stage counts do not match; sample_raw.json has 5 records, but sample_std.json and sample_sft.json have 4.
• androidcontrol: standardized ids (0, 20, 40) do not match SFT ids (androidcontrol-0, androidcontrol-1, androidcontrol-2).
• CharlieDreemur_OpenManus-RL: three of five standardized trajectories end on an api_action such as perform_action or a weather API call without a following observation or final answer.
• agenttuning_os: a second task is appended after a completed first task, making one ADP trajectory contain multiple independent OS problems.

Suggested work

• Add or strengthen tests requiring sample stage counts and ids to align across raw, standardized, and SFT files.
• Ensure converters preserve the same record order through the pipeline.
• Avoid dropping raw records silently during standardization or SFT conversion; if filtering is intentional, document and encode it deterministically.
• Require trajectories to end with a plausible terminal state, final answer, or documented reason for truncation.
• Split multiple independent tasks into separate trajectories where appropriate.
• Keep representative samples small but broad enough to cover important action/observation edge cases.
