Headroom Daily: The Loop Detector Gets an Overhaul
Three separate fixes converged on the same problem in the "learn" command's loop detector, while a pair of performance patches cut unnecessary work in the memory and cache layers. Together, they point to a codebase tightening up correctness and efficiency ahead of broader use.

Good morning. It's September 7th, and here's what mattered in the headroom codebase today.
The clearest pattern today is a cluster of fixes to the "learn" command's loop detector. Three separate pull requests — 3461, 3462, and 3455 — all attack the same underlying issue: the detector was grouping tool calls using values built for display, not identity. PR 3461 found that truncated summaries were merging…
Second theme: performance work in storage. PR 3466 batches memory reindexing instead of committing one transaction per record, and PR 3465 stops decoding every cached payload just to check if it's expired, replacing that scan with a metadata-only delete. Both are the same lesson — read only what you need from the…
Worth flagging on its own: PR 3457 fixes a subtle proxy bug where repairing tool-search history could shift the coordinates of signed thinking blocks in Claude Code traffic, which is the kind of bug that fails silently until signature verification breaks downstream.
What's next: watch for the loop-detector fixes to land together, since they touch overlapping logic. And the Codex Live HTTP fix, PR 3464, still has an open change request — worth checking before it merges.
That's…
