Found a real upstream bug while checking codegen reproducibility: relspec templ's @TableIndex ordering is non-deterministic (content-identical, order differs) on 6 of the 18 tables — this will cause spurious failures on the "clean diff" CI gates both docs promise for regeneration. Worth filing against relspecgo.

Verification completed:

  • Regression first reproduced nondeterministic output before the fix.
  • TMPDIR=$PWD/.tmp GOCACHE=$PWD/go-cache go test ./pkg/writers/template -run TestWriterTableIndexValuesDeterministic -count=1
  • TMPDIR=$PWD/.tmp GOCACHE=$PWD/go-cache go test ./pkg/writers/template ./pkg/reflectutil -count=1
  • TMPDIR=$PWD/.tmp GOCACHE=$PWD/go-cache go test ./pkg/writers/... -count=1
  • TMPDIR=$PWD/.tmp GOCACHE=$PWD/go-cache go test ./... -count=1
  • TMPDIR=$PWD/.tmp GOCACHE=$PWD/go-cache make test
  • git diff --check

Completed and merged via PR #11. Independent review confirmed the template values path now sorts map keys deterministically, repeatedly generated TableIndex output is byte-identical and lexically ordered, gofmt and git diff --check pass, and go test ./... passes. Feature SHA: c2def00bcf.
