# Engram re-anchor hook for DeepSeek Harness's Claude Code hook bridge.
# dsh's bridge consumes ONLY the JSON hookSpecificOutput.additionalContext
# shape — plain SessionStart stdout is discarded (documented dsh limitation),
# so this wrapper emits what Claude Code's JSON hook contract allows and dsh
# actually reads. Degrades to silence on any failure; prints nothing (valid:
# no output) when no reviews are due.
