The OpenAI commercial capability table floor is now gpt-5.4: o1, o1-mini, o3, o3-mini, o3-pro, o4-mini, gpt-5, gpt-5-mini, gpt-5-nano, gpt-5-pro, gpt-5.1, gpt-5.1-codex-max, gpt-5.2, gpt-5.2-pro, and gpt-5.3 are effectively unused in the field. The gpt-5-search-api row (different product surface) and the audio/STT/TTS rows stay. A legacy id now resolves to OPENAI_DEFAULT (temperature sent, no declared effort vocabulary, 200K window) — which those models may reject; the remediation is the model definition's capabilities JSON or a current model, release-noted under Unreleased → Removed. This also retires the transport-collapse review's thrice-reported "stream-rejecting o1-era models are stranded" finding by removing its subject: no row in the table describes a non-streaming model anymore. Tests migrate to 5.4-era equivalents that pin the same behaviors: always-reasoning temperature suppression and off-list effort snap (gpt-5.4-pro for gpt-5-pro/o3), explicit-none forwarding (gpt-5.4 for gpt-5.1), empty-effort-vocabulary knob drop (gpt-5-search-api for o1-mini), and the longest-prefix shadow hazard (gpt-5.4-pro vs gpt-5.4 for codex-max vs gpt-5.1).

"""Provider-layer tests for the internal ``document`` content-part type.
