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.

Error redaction covers invalid HTTP header messages

Under the hood
Useful2 Signal0
Telemetry

Error and telemetry text now scrubs invalid HTTP header values so they can't leak into reports.

What

Two more patterns were added to the telemetry and error scrubber so header values do not leak through error text.

Details
  • One pattern truncates everything after "has invalid value: " for a named header.
  • The other covers Headers.append and Headers.set messages about an invalid header name or value.
Evidence

has invalid value:

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