- 2026-04-24: lua: scoreboard iteration — added `lua-unwrap-final-return` (post-processor that rewrites top-level `(raise (list 'lua-ret V))` → `V` so top-level defines leak to SX top and loadstring closures can see them). Tried dropping the function-guard at top level, but too many tests use `if x then return 0 else return err end` at chunk tail, whose returns aren't at the *statement-list* tail — guard still needed. Kept guard + unwrap-as-no-op. Scoreboard unchanged.
- 2026-04-24: lua: scoreboard iteration — `lua-pat-strip-captures` helper lets patterns with `(...)` capture parens at least match (captures themselves aren't returned yet — match returns whole match). Unblocks common Lua pattern idioms like `(%a+)=(%d+)`. Scoreboard unchanged.
- 2026-04-24: lua: scoreboard iteration — extended pattern engine to `string.match`/`gmatch`/`gsub`. `gsub` now supports string/function/table replacement modes. 381/381 green (+6 pattern tests).
- 2026-04-24: lua: scoreboard iteration — **Lua pattern engine (minimal)** for `string.find`. Supports character classes (`%d`/`%a`/`%s`/`%w`/`%p`/`%l`/`%u`/`%c`/`%x` + complements), `.` any, `^`/`$` anchors, quantifiers `*`/`+`/`-`/`?`, literal chars, `%%`. Added `plain` arg pathway. match/gmatch/gsub still literal. Scoreboard unchanged (pattern-using tests still hit other issues downstream).
