## Revendor history

| Grammar | tree-sitter-m | Notes |
|---------|---------------|-------|
| v0.1.2 | commit `c796342` (PR #7) | YottaDB m-modern-corpus coverage: `&`/`$&` external C call-outs, `WRITE`/`USE` `/mnemonic` device controls, `TSTART`/`LOCK` argument-list `:timeout`, `KILL *`/`TSTART *`, extended reference `^\|env\|gvn` / `^[env]gvn`. Additive grammar.js only — `scanner.c` unchanged. ABI unchanged (15). |
| v0.1.1 | commit `94eb80d` | prior baseline. |

**Parse-coverage impact of the v0.1.2 grammar** (files with a literal
`(ERROR)` node, full corpora):

| Corpus | before (v0.1.1) | after (v0.1.2) |
|--------|-----------------|----------------|
| m-modern-corpus (4,215 YDB routines) | 451 err / 89.30 % clean | **230 err / 94.54 % clean** |
| VistA (39,330 routines) | 363 err / 99.08 % clean | **336 err / 99.15 % clean** (held; slightly improved) |

The VistA corpus did not regress. **Follow-up:** m-cli must bump its
m-parse dependency to pick up this grammar.
