Claude Code v2.1.235

More subsystems routed through an alternative storage backend that this build never creates

Not switched on
Useful1 Signal5
Storage Backend Notable

Compaction, history purge, session moves, recordings and skill reads all gained storage-backed twins that never run.

Six subsystems have a second implementation routed through an optional storage layer whose factory has an empty body, so every branch falls back to the filesystem.

Feature flag
tengu_hover_rest Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

What

Transcript compaction, history-purge counting and rewriting, session-directory moves, asciicast recording writes, a deep-link registration marker and skill-as-plugin SKILL.md reads all gained a second implementation that goes through an optional storage layer. None of it can run here: the factory that would build that layer has an empty body and returns nothing, so every one of these branches falls back to the normal filesystem code.

Details
  • Each branch is selected only when the gate tengu_hover_rest (fallback off) is on and a backend object exists, and the gate value is read once per process.
  • The alternative compaction path carries its own failure reasons snapshot_mid_line, shared_inode and source_changed, reported under tengu_transcript_compact_failed.
  • The session-move path includes a warning for leftovers stranded by a partial move.
