A `/facts` aggregate row carries no certname, so the per-certname fact
merge collapsed every backend's rows into one bucket and served a single
backend's numbers.
- Route a `/facts` query whose `extract` carries a `function` column to
serveSummed, as /nodes, /resources and /reports already do
- Document which extract functions combine correctly across backends
Every merge rule, AST gate and provenance decision was derived from reading
upstream source and proven only against fake backends, so nothing had ever run
against a real PuppetDB.
- Add an e2e suite behind the `e2e` build tag and a `make e2e` target
- Stand up two openvoxdb backends on their own PostgreSQL with testcontainers
- Load facts, reports and catalogs over the command API, waiting on processing
- Assert the union, freshness dedupe, summed aggregates, provenance gating,
X-Backends, backend death and recovery, and the report paths
- Drive Puppetboard and node-lookup against pdbmux as real clients
- Record three known gaps as skips that fail once the gap closes
