PACTBench evaluates a layered boss-control system across V Rising, Hollow Knight, and The Binding of Isaac:

This directory is the release unit for code, checkpoints, published metrics, and reproducibility metadata. Machine-readable publication state lives in registry/registry.json; prose never overrides the registry or the referenced metric files.

The published snapshot uses fight-disjoint splits, the compact belief interface, balanced-v3 L2 sampling, HP-free-v6 prompts, anonymous option IDs, Gemma-4-E2B-it at temperature zero, and deterministic sample seed 0.

Isaac distance is measured in pixels and is not directly comparable to the engine-unit distance used by the other two games.

The 200 source states are fixed before L2 outputs are read. Isaac has 122 valid semantic-swap pairs because the predefined intervention requires at least two tracker-ready options; singleton menus are excluded before outcome aggregation. The fixed two-choice controls are reported separately in docs/EXPERIMENTS.md.

The L1 visual comparison is a comparison of complete training schemes: PACT-L1 is task-trained end to end, whereas DINOv2-S and VideoMAE-B are frozen pretrained backbones with trained probes. It is not an isolated backbone claim.

V Rising also includes a separate accepted L1 comparison experiment that trains DINOv2-S end to end on the same ordered 18,068/8,075 rows and the matched PACT two-stage recipe. In this configuration it remains less accurate and 48.79% slower at batch 1 than PACT-L1; the evidence and claim scope are recorded in docs/EXPERIMENTS.md.

The full artifact gate should end with:

Large raw data and RGB caches are exposed through data -> ../data and out -> ../out. See the reproducibility guide before rebuilding or moving them.

The decision-quality LLM judge is intentionally run on a separate machine. Its absence from the local deterministic gate does not change the publication status of the local L1 and L2 intervention artifacts.
