Research direction
Start with scripts/brainlayer-version-check.sh and trace how the canonical package version, tap root, and BrainBar cask are resolved. Add regressions for formula-behind, formula-ahead, formula-equal, cask-lag with formula equal, and an unresolvable formula version. Done means formula drift always fails, while the explicit cask-lag allowance remains limited to the cask.
Written by the indexing model from the issue text.
Description
Gap
scripts/brainlayer-version-check.sh validates BrainLayer package metadata and the BrainBar cask, but it does not read the Homebrew brainlayer formula. A tap can therefore advance the cask while leaving the formula behind and still pass the version gate.
This happened before the 1.5.32 release: the cask was 1.5.31 while the formula—and the keg interpreter every pinned hook resolves through—remained 1.5.30. A rehearsed 1.5.32 cask-only tap also passed the script.
Required behavior
- when a tap root is supplied, resolve the
brainlayerformula's stable version from its URL/version stanza - fail if the formula is behind or ahead of the canonical package version
- keep the existing explicit cask-lag allowance scoped to the cask only; it must never excuse formula drift
- add regressions for formula-behind, formula-ahead, formula-equal, and cask-lag-with-formula-equal
- fail closed when the formula exists but its version cannot be resolved
Release-time evidence
For v1.5.32 the gap was covered manually on both Macs: the tapped formula URL was read as 1.5.32, brew list --versions brainlayer included 1.5.32, and /opt/homebrew/opt/brainlayer resolved to Cellar/brainlayer/1.5.32. This issue is the automation follow-up, not a claim that the 1.5.32 install is unverified.
