distribution/tests/publish_persist.sx

// Regression for P3.4a-001 — `dist ci publish` must LOAD an existing
// `<store>/db.json` before publishing, so separate CLI invocations SHARE
// state through the store (not start from an empty Repo and clobber it).
//
// Drives the BUILT `build/dist` binary (via `process.run`, like
// publish_happy.sx) twice into ONE store and asserts cross-invocation
// persistence:
//
//   1. Publish version A (1.2.3) into a fresh store → db.json has the release.
//   2. Publish a DIFFERENT version B (1.2.4) of the SAME app into the SAME
//      store → exit 0, and db.json now records BOTH releases under ONE app
//      (the app is FOUND, not duplicated); the channel points at the latest
//      release B; both content-addressed objects exist.
//   3. Re-publishing the SAME release id (A again) into the same store FAILS
//      (exit != 0 — the P2.3 integrity transaction rejects the duplicate
//      release id) and leaves db.json UNCHANGED (still two releases).
//
// FAIL-BEFORE / PASS-AFTER: against the pre-fix publish (which never reads
// db.json and so begins every invocation from an EMPTY Repo) step 2 CLOBBERS
// A — db.json ends with one release, not two — and step 3 "succeeds" (exit 0)
// and overwrites. Both assertions fail. After the load-then-merge fix they
// pass. Fresh store per run.
