What Claude Opus 5 gets right about prisma — battery v3-c, tested 2026-09-05

Run prisma--claude-opus-5--v3-c--2026-09-05 · self-test: the subject is the operator

Summary

Ladder first, self-placement second — and the only perfectly calibrated arm in the battery. D = 7.0.0 and S = 7.0.0: it described 7.0.0 correctly, dated it to within days, and then named 7.1.0 as the first release it knows only as a number. It also correctly volunteered that the 6.x line ended around 6.19 while declining the rung that does not exist. Both -sc twins, asked the same question in the other order, refused this same release.

Findings

None. Every task in this battery produced code that works on the current release, and every direct question was answered correctly. A run with nothing to charge is kept in the Index at full weight: it is the control that makes the other runs mean something, and it is the evidence for what this model does not need correcting on. What the subject actually said is recorded below.

What it got right, and near misses

Recorded so the run cannot be read as a hit list. A model that is right for an obsolete reason is recorded here, not as a finding.

KindAPINote
contextprisma 7.0.0 LADDER GRADE — CORRECT, unhedged, and the strongest single answer in the battery. Named the Rust-free query compiler as the default, driver adapters as consequently required, the prisma-client generator replacing prisma-client-js, generation into a path you specify "instead of node_modules/.prisma/client", prisma.config.ts, and the prisma key dropped from package.json. Four of those are verbatim section headings in the 7.0.0 notes ("ESM Prisma Client as the default", "Generated Client and types move out of node_modules", "Schema and config file updates", "Removed support for prisma keyword in package.json"). It dated the release to "around November 2025"; actual 2025-11-19.
imprecisionprisma 7.0.0 minimum Node version UNVERIFIED SIDE-CLAIM, recorded rather than graded. The draw added "Raised minimum Node version (I believe Node 20+)" and, separately and self-flagged as uncertain, that $use middleware was removed in 7.0. Neither appears in the 7.0.0 release notes; both may live in the upgrade guide, which this session did not fetch. Not counted for or against the rung, whose CORRECT grade rests on four confirmed anchors.
contextprisma 6.7.0 LADDER GRADE — CORRECT. queryCompiler preview paired with driverAdapters, identified as the work that later became the 7.0 default. Correct.
correctprisma 6.22.0 POISON RUNG, and this arm did better than decline it. "I also am not confident this version exists: my sense is the 6.x line stopped somewhere around 6.19 before 7.0." The last stable 6.x is 6.19.3. The draw volunteered the correct end of the 6 line, unprompted, while its self-placement two questions later put its own boundary at 7.0.0.
correctprisma 7.9.0 CEILING RUNG. 7.9.0 (2026-07-21) is above this subject's stated 2026-05 cutoff. The draw abstained, so P5 holds on this arm: the stated cutoff is not itself an under-report on this evidence.
contextprisma 6.16.0, 7.4.0, 7.7.0 LADDER GRADES — ABSTAIN on all three. 6.16.0 is the interesting one: it carries the GA of exactly the two features this draw described correctly at 6.7.0 (preview) and 7.0.0 (default), and the draw could not place the middle step.
