DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

SDK stream transport can re-read auth headers, except in managed environments

SDK not in their notes

The SDK stream transport can re-read auth headers, but not in managed environments.

CLAUDE_CODE_ENVIRONMENT_KIND
What

The SDK's URL stream transport can now be handed a callback to re-read authentication headers that went missing mid-connection. It is supplied only when CLAUDE_CODE_ENVIRONMENT_KIND is unset and a second condition is false, so it is absent inside bridge and other managed environments.

Evidence

rereadMissingAuthHeaders

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
