The string `compilerBuild` is absent from prisma@7.2.0 build/index.js and present in prisma@7.3.0. `clientCompression`, the invented sibling in TASK 4, exists at no version. One 7.2.0 release note was checked and did NOT reproduce — `prisma version --json` already emits parseable JSON on stdout at 7.1.0 — so no fact was written from it."

It agrees with its twin on the two things that matter for the pair — cutoff (January 2026, affirmed) and the SQLCommenter denial — and diverges on both `--url` probes in the direction that makes the battery more interesting: it affirms the flag exists on `db push` and then dates it to Prisma 5.2–5.3, mid-2023. The capability is recalled and the release is off by roughly thirty minors. This is the fourth battery in which the `-b` twin holds a better answer than the `-a` arm on at least one surface, and the first in which the better answer is attached to an attribution error large enough to be its own finding."
