 Each grammar is the work of its upstream authors and each grammar directory
 contains the upstream `LICENSE` file.

 ## Summary
 
-- Grammars: **156** — vendored-from-upstream: **139**, first-party/self-maintained: **12**, registry-disagreement: **5** (nim removed 2026-06-12, see below)
+- Grammars: **158** — vendored-from-upstream: **141**, first-party/self-maintained: **12**, registry-disagreement: **5** (nim removed 2026-06-12; objectscript_udl + objectscript_routine added 2026-06-24 — see note below)
 - ABI distribution: **7×** ABI-13 **85×** ABI-14 **64×** ABI-15 (runtime ceiling is ABI 15; never vendor ABI 16 without a runtime upgrade)
 - Vendored copies missing LICENSE: **0** — all upstream LICENSE files restored 2026-06-11 (first-party grammars carry the project MIT license; `move` uses the Helix-listed upstream tzakian/tree-sitter-move MIT text, `zsh` uses georgeharker/tree-sitter-zsh MIT)
-- `verdict`: VERIFIED-BOTH = our source matches *both* registries; VERIFIED-NVIM/HELIX = matches one; registry-disagreement = registries name a different repo (listed separately).
+- `verdict`: VERIFIED-BOTH = our source matches *both* registries; VERIFIED-NVIM/HELIX = matches one; registry-disagreement = registries name a different repo (listed separately); `vendor-maintained` = the language vendor's own grammar, not in nvim/Helix.
+- **objectscript_udl / objectscript_routine** (added 2026-06-24): vendored from [intersystems/tree-sitter-objectscript](https://github.com/intersystems/tree-sitter-objectscript) @ `a7ffcdf` — MIT, the InterSystems-official grammars (a niche vendor language, hence `vendor-maintained`, not in nvim-treesitter/Helix). **Re-vendor note:** each `scanner.c`'s upstream `#include "../../common/scanner.h"` is repointed to a per-directory `objectscript_common.h` (a verbatim copy of upstream `common/scanner.h`), because this repo's shared `vendored/common/scanner.h` belongs to the cfml/fsharp grammars and differs. The generated `parser.c`/`scanner.c` are otherwise byte-for-byte upstream — on re-vendor, re-apply only that single include rename.
