v0.83.0 Release Recap

v0.83.0 is a non-breaking KV audit release that adds receipts for executed graph-derived KV refreshes.

What's New

Area	New in v0.83.0	Why it matters
Derived KV receipt	contextdb repair kv-cache --derive recent-nodes --execute --receipt-out PATH	Records durable evidence after a reviewed derived cache refresh
Value integrity	SHA-256 hash of the reviewed derived value	Lets incident records prove which payload was written
Doctor follow-up	recommended_doctor_command in the receipt	Gives operators a copyable confirmation command for refreshed derived keys
Feature metadata	kv-derived-refresh-receipt	Lets live deployments advertise derived KV refresh receipt support

Operator Flow

contextdb repair kv-cache \
  --key context:prod:support:recent-nodes \
  --derive recent-nodes \
  --derive-namespace support \
  --derive-label SessionContext \
  --execute \
  --receipt-out context-prod-support-recent-nodes.receipt.json \
  --report

--receipt-out requires both --execute and --derive recent-nodes. The receipt stores the executed refresh report, value hash, and a doctor confirmation command.

Compatibility

This release is intentionally non-breaking. Existing dry-run reports, literal/file KV refreshes, derived values, TTL behavior, overwrite behavior, and doctor checks are unchanged unless --receipt-out is supplied.

Verification

Release verification included:

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