Good morning, it's Tuesday, September 29th, 2026, and this is Headroom Daily.

The clear signal today is a coordinated lockdown of the proxy, paired with fixes to keep compressed memory actually retrievable.

First, the proxy is going fail-closed. PR 3847 moves extension middleware inside authentication and the request size ceiling, after tests showed a plugin could answer unauthenticated callers or buffer a hundred-megabyte upload before any check. That pairs with PR 3853 in the Rust proxy, which now rejects paths with…

Second, memory retrieval gets more reliable. PR 3839 unwraps Hermes batched tool calls so retrieved content stays exempt from recompression, after whole results came back as unreachable markers. Related fixes in 3810 and 3816 inject the retrieve tool before the prompt cache warms and answer it on the direct chat…

Third, operator experience and cost accuracy. PR 3855 teaches wrap, init and doctor to respect relocated Codex homes and find a live proxy on another port instead of starting a duplicate or pointing at a squatter. PR 3841 corrects fallback pricing and lifts the context window to one million for Claude Sonnet 5.5,…

What's next: eight open hardening proposals…
