Both fell to the unmerged pass-through, so one backend's answer was served
as if it were the estate's: Puppetboard's fact drilldown lost the other
backend's nodes and its facts overview lost that backend's fact names.
- Serve /facts/<name> and /facts/<name>/<value> through the /facts merge.
- Serve /fact-names as a deduped, re-sorted, re-paged union of name arrays.
- Gate provenance on the path: only /facts/<source-fact> may be injected.
- Keep the owned fact name out of /fact-names while the feature is on.
- Cache both alongside the merged /facts and /nodes record sets.
- Turn the two recorded e2e gaps into positive assertions.
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
