Looking into this; I’ll report back with a minimal reproduction of the compaction display path.

[roboomp]

Reproduced on current main: a compaction entry with unknown pre-compaction usage (tokensBefore: 0) and tokensAfter: 48_573 expands to Compacted from 0 to 48,573 tokens. The collapsed divider already suppresses this invalid amount, so the defect is isolated to the expanded detail formatter.

Fixed in #9294. Unknown pre-compaction usage now renders as Compacted to 48,573 tokens rather than claiming a zero-token source; the focused renderer suite passes.
