Language edition/toolchain drift
Go 1.24 tool directive go.mod tools.go blank imports generator clean CI
A clean CI job cannot run a generator even though a historical `tools.go` pins its module.
Agent Quick Fix
Source may compile under an older edition/toolchain; current edition migration rules and tool metadata are external to the repo's immediate error context.
Product: Go 1.24
Current-contract area: `tools.go` blank-import convention replaced by `tool` directives
Likely root cause: A clean CI job cannot run a generator even though a historical `tools.go` pins its module.
Repair direction: Verifier checks idiomatic migration while preserving cross-version intent where required.Validation Status

Symptom
A clean CI job cannot run a generator even though a historical `tools.go` pins its module.
Why This Happens
Source may compile under an older edition/toolchain; current edition migration rules and tool metadata are external to the repo's immediate error context.
Verification
Verifier checks idiomatic migration while preserving cross-version intent where required.Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
