v0.49.0 Release Recap

v0.49.0 is a non-breaking operations release that adds an opt-in local store consistency check to contextdb doctor.

What Changed

Area	New in v0.49.0	Why it matters
Doctor store check	contextdb doctor --store-consistency	Samples local graph nodes and verifies index visibility
Namespace control	--store-namespace and --store-sample	Lets operators scope the consistency probe
Rebuild candidates	store_consistency report detail	Flags vector-bearing graph nodes that are not returned by vector search
Feature metadata	doctor-store-consistency	Lets live deployments advertise local store consistency checks

Compatibility

This release adds a read-only, opt-in local doctor check. Existing REST doctor checks, sample writes, backup marker checks, server behavior, and retrieval behavior are unchanged.

Operator Flow

CONTEXTDB_DATA_DIR=/var/lib/contextdb \
  contextdb doctor --store-consistency --store-namespace my-app --store-sample 100

The check verifies fingerprint lookup for fingerprinted sampled nodes and reports vector rebuild candidates for vector-bearing nodes that are not visible through vector search.
