What

Follow-up to #15 from the first kaiser-soze lane run on the new agents (see the new section in docs/research/usage-insights-2026-10.md).

• builder: one Read per file, no chained cat/sed -n; change files with Edit/Write, not inline Python.
• hall-monitor: read whole files with Read, never cat; find callers with the LSP tool's findReferences when available, else grep (trial; tool name unverified against a session with the plugin enabled).
• orchestrate: a choice between designs, such as a timeout or fallback, goes to the user even in a fix round.
• Version bump to 2.4.1; Codex and Cursor copies rebuilt.

Checks

build_agents.py --check, test_install.py and git diff --check pass.

Open

One lane is a direction, not a result. Recount shell-read share per agent after more sessions, and count LSP calls in hall-monitor.
