v1.6.0
KNOWN ISSUE: do not use the kleos-sidecar binary from this release.
The 1.6.0 kleos-sidecar over-ingests raw session content. It ships every raw tool result to durable storage (retain_tool_calls defaulted to true) and the file-watcher gate appended the full raw assistant turn to its one-line summary, flooding the memory store with low-signal data and degrading recall. The session-start eidolon prompt also emitted a duplicate context banner and injected memory content without credential scrubbing.
Fixed in 1.6.1. Until 1.6.1 is published, build kleos-sidecar from main, or set KLEOS_RETAIN_TOOL_CALLS=false to stop the worst of the over-ingestion.
