Good morning. It's August 9th, and this is Headroom Daily.
The clearest pattern today is Headroom's proxy team closing gaps where the system was quietly lying to itself about cost and correctness. Tejas Chopra's fix in commit 675d13f, mirrored in pull request 2872, found that the Responses API path never ran response hooks the way chat completions did — meaning a hook could…
Two more proxy fixes follow the same theme of surfacing hidden truth. Pull request 2880 fixes the savings ledger to actually include tool-search deferral savings, which had been under-reporting real gains. And pull request 2875 bounds two internal cache tables that were growing unchecked even while the main…
Anthropic compatibility also got attention. Pull request 2876 extends last week's tool-search history repair to cover Headroom's own retrieval mechanism, since Claude Code can replay a transcript against a request with a different tools array than when it was recorded.
Second theme: routine security hardening spread across repositories — a git-python upgrade in pull request 2870, input sanitization in a deployment script in pull request 2873, and disabling external XML entity processing in a feed parser in…
