# Trajectory2Gym: decision-grounded candidate interactions
This release contains **34,772 complete, policy-visible candidate interactions** for tool-use post-training, stored in seven compressed JSONL shards. These are semantic parents, not rendered children or a final scale-specific training view.

Each model repository contains native tokenizers, chat templates, model cards, licenses, and release checksums. The candidate corpus below is not the rendered scale-specific training data; the 30B-A3B model uses an expanded corpus.
## Record format
Records preserve native messages, tool definitions, supervised assistant-turn indices, context-turn counts, and stable source identities. The supervision mask selects assistant decisions; user/tool messages and masked failed actions can remain visible context.
Operational source paths and non-allowlisted top-level collection metadata are omitted. Dialogue content, native tool arguments, tool definitions, and supervision indices were checked against every original record, including nested dictionary ordering.
## Loading
Native tool schemas and argument values are heterogeneous. Use a JSONL reader rather than assuming all records can be inferred as one flat Arrow schema.

## Scope and provenance
The source is the frozen training-side candidate corpus. Tau1 Airline uses the disclosed seen-task construction/evaluation scope. Tau2 construction uses its official train partition. This release does not assert template-level separation, and it is not the current upstream benchmark test distribution. The 30B-A3B study uses an expanded corpus, not this common pool alone.

See provenance.json and RELEASE_MANIFEST.json for the transformation and file hashes. Exported bytes differ from the historical source file. Native reset states and all execution certificates are not included, so these files are not a standalone environment replay package.
## Content checks
Credential patterns, internal-host strings, and operational paths were checked. Benchmark-native simulated address literals and a generic path placeholder were retained through an exact-value-hash review bound to the source hash; see NATIVE_LITERAL_REVIEW.json. That review is not an independent human PII audit. Native fixture entities are retained to preserve observation-to-action dependencies.
