OpenAI corrected the GPT-5.6 Sol, Terra and Luna context windows to 272k in Codex CLI 0.144.6, and 0.145.0's bundled models.json still reports 272000 for all three. The OAuth transform kept the earlier 372k input override, which delays compaction past the window the Codex harness advertises. That makes 5.6 identical to 5.5, so the two branches collapse into one.

The following comment was made by an LLM, it may be inaccurate: Found Related PRPR #38987: fix(core): honor Codex input limits This PR is related to your current PR #39082. Both address Codex model limits and input handling. PR #38987 focuses on the core layer honoring Codex input limits, while your PR corrects the OAuth transform's GPT-5.6 context window from 372k to 272k. These appear to be complementary fixes for the same issue (#38976) affecting different layers of the system. |

Type of change
What does this PR do?
The Codex OAuth transform still pins GPT-5.6 Sol/Terra/Luna to a 372k input window. OpenAI corrected those context windows to 272k in Codex CLI 0.144.6, so we were letting sessions run past the window the Codex harness itself advertises, which delays compaction.
Codex 0.145.0's bundled
models.jsonreportscontext_window: 272000for all three 5.6 variants — the same as 5.5. Since the two branches now produce an identical object, I merged them rather than duplicating it.Only affects the OAuth path; API-key metadata still uses the provider's own limits.
How did you verify your code works?
