v0.63.0 Release Recap

v0.63.0 is a non-breaking durability release that lets KV cache repair derive reviewed session context values from graph data.

What Changed

Area	New in v0.63.0	Why it matters
Derived KV value	contextdb repair kv-cache --derive recent-nodes	Builds a compact recent-node session context payload from valid graph nodes
Derivation scope	--derive-namespace, --derive-label, and --derive-limit	Lets operators control which graph facts feed the reviewed cache value
Dry-run review	Existing --report and --execute behavior is preserved	Keeps generated values inspectable before they are written to KV
Feature metadata	kv-cache-derived-recent-nodes	Lets live deployments advertise support for graph-derived KV refresh values

Compatibility

This release only adds optional contextdb repair kv-cache flags and feature metadata. Existing literal values, value-file refreshes, dry-run reports, overwrite behavior, TTLs, and execute flow are unchanged.

Operator Flow

contextdb repair kv-cache \
  --key context:prod:recent-session \
  --derive recent-nodes \
  --derive-namespace prod \
  --derive-label SessionContext \
  --derive-limit 5 \
  --report

Review the generated JSON payload first, then add --execute when it is ready to write.
