Opus 4.7 audit of the codebase surfaced several items that Opus 4.6
sessions left behind. This pass removes what's definitively dead and
fixes one trivial defensive bug; the real logic bugs (transaction
ordering, missing RunUpdate/RunDelete validation) come in a separate
commit.
Deletions:
- `_FiveSql2/src/TSqlParser_orig.prg` (1173 lines) — superseded by
`TSqlParser2.prg` (Pratt). Production never instantiates the old
parser; the only callers were the comparison/benchmark test files
also being removed.
- `_FiveSql2/test/test_parser_cmp.prg` — compared orig vs Pratt AST,
useless now that orig is gone.
- `_FiveSql2/test/bench_parser.prg` — benched both, same reason.
- `_FiveSql2/Makefile` `test_cmp:` and `bench:` targets referenced
the removed files.
- `TSqlIndex.prg` methods `ApplyScope`, `ClearScope`, `ApplySeek`,
`IndexInfo`, `CreateTempIndex`, `DropTempIndex` — each declared in
the class header and implemented (~165 lines total) but zero
callers anywhere in `_FiveSql2/` or `hbrtl/`. Class declarations
removed alongside the bodies.
Small fixes:
- `TSqlDDL.prg:179-180` stale comment claiming Five doesn't support
`@byref` — false since commit e95afad (2026-04-13) wired @byref
via RefCell. The same method uses @nPos correctly elsewhere.
- `hbrt/class.go:tryBinaryOp` defensive nil-check on AsArray().
IsObject() checks the type tag; a corrupted Value with tag=Object
but ptr=nil would crash on `.Class`. Correct construction paths
never hit this, but the guard is cheap.
Compat tests: FiveSql2 43/43, Harbour compat 56/56, Go test ALL PASS.
