What
When the layout engine throws while measuring the terminal UI, Claude Code now clears its cached layout for the whole tree and retries once. If the retry works the frame draws normally; if it throws again that single frame is dropped and the session carries on instead of crashing. This is in the normal render path for everyone on this build, not behind a flag.
Details
- Each distinct fault message is reported to error tracking at most once, plus a one-shot report when faults keep recurring across many consecutive frames.
- Warn-level debug lines for these faults are capped.
Evidence
ink layout pass threw; immediate re-layout also threw, frame dropped
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
