- 2026-04-24: lua: phase 4 — metatable dispatch (`__index`/`__newindex`/arith/compare/`__call`/`__len`), `setmetatable`/`getmetatable`/`type` globals, OO `self:method` pattern. Transpile routes all calls through `lua-call` (stashed `sx-apply-ref` to dodge user-shadowing of SX `apply`). Skipped `__tostring` (needs `tostring()` builtin). 247 total tests.
- 2026-04-24: lua: PUC-Rio scoreboard baseline — 0/16 runnable pass (0.0%). Top modes: 14× parse error, 1× `print` undef, 1× vararg transpile. Phase 3 complete.
- 2026-04-24: lua: conformance runner — `conformance.sh` shim + `conformance.py` (long-lived sx_server, epoch protocol, classify_error, writes scoreboard.{json,md}). 24 files classified in full run: 8 skip / 16 fail / 0 timeout.
- 2026-04-24: lua: vendored PUC-Rio 5.1 test suite (lua5.1-tests.tar.gz from lua.org) to `lib/lua/lua-tests/` — 22 .lua files, 6304 lines; README kept for context.
