v0.27.0 Release Recap

v0.27.0 is a non-breaking restore audit release. Promotion receipts can now be verified against their original artifact manifests.

What's New

Area	New in v0.27.0	Why it matters
Receipt verifier	contextdb snapshot receipt verify --promotion-report receipt.json --manifest backup.manifest.json	Confirms a promotion receipt lines up with the exported artifact metadata
Record-count comparison	Imported line, node, edge, and source counts are compared with manifest counts	Catches mismatched or stale promotion receipts
Namespace consistency	Receipt namespace must match the embedded import report namespace	Helps detect edited or malformed receipts
Backup identity check	Receipt backup filename is compared with the manifest backup file	Links promotion receipts back to the intended artifact
Feature metadata	promotion-receipt-verify	Lets deployments advertise support through introspection

Compatibility

Receipt verification is additive. Existing export, verify, rehearse, import, receipt, marker, and doctor workflows keep their behavior unchanged.
