v0.79.0 Release Recap

v0.79.0 is a non-breaking operations documentation release that adds a guarded execution recipe for stale graph-derived KV cache repairs.

What's New

Area	New in v0.79.0	Why it matters
Stale KV repair recipe	Doctor hint to dry-run to execute checklist	Gives operators a repeatable path from kv_derived_freshness failure to reviewed refresh
Payload review	Explicit checks for namespace, labels, count, generated timestamp, and compact node list	Keeps derived session context from being refreshed with the wrong scope
Confirmation step	Rerun doctor after --execute	Verifies the hot key is present and fresh after repair
Feature metadata	kv-derived-repair-execution-recipe	Lets live deployments advertise the execution recipe in docs and feature introspection

Operator Flow

Start with doctor:

contextdb doctor \
  --kv-derived-key context:prod:support:recent-nodes \
  --max-kv-derived-age 2h \
  --report

When kv_derived_freshness fails, run the recommended_repair_command as a dry run, review the derived payload, then repeat with --execute --report. Rerun doctor with the same key and freshness window before closing the incident.

Compatibility

This release is intentionally non-breaking. It updates docs and feature metadata only; existing doctor checks, repair commands, derived payloads, and write behavior are unchanged.

Verification

Release verification included:

go test -count=1 ./cmd/contextdb
go test -count=1 ./...
npm run docs:build
git diff --check
