The vendored LICENSE carried tree-sitter-typescript's MIT text plus an
appended derivative notice. That is not what MIT asks of a derivative -- it
asks that upstream's notice travel with the code -- and the appended text
meant the provenance audit could not byte-verify the file against upstream,
so arkts landed as NO-MANIFEST-ENTRY and failed license-gate.
The vendored LICENSE is now byte-identical to upstream's, and arkts is
registered in the audit's FORKS map, which is defined for exactly this case:
a self-maintained fork whose vendored LICENSE must match its upstream. That
is a routing entry, not an exemption -- check_upstream still byte-verifies
against the real upstream repository, so the fact is checked rather than
asserted. Audit now reports arkts as IDENTICAL.
Our copyright for the ArkTS additions is not lost, it moves to where our
SOURCE is: the grammar.js header (which now states all three copyrights
explicitly) and THIRD_PARTY.md, which ships inside the release archives.
The edit to scripts/audit-license-provenance.py is a maintainer-only
enforcement-surface change, made deliberately and stated here rather than
slipped in; a contribution may never supply its own audit entry.
No generated parser or source changes -- comments, licence text, manifest
prose and one routing entry only.

Routing .ets through the plain TypeScript grammar produced no definition
node for any @Component struct (0/19 across the OpenHarmony sample corpus),
parsed struct members as statement labels and build() as a call expression,
and registered ArkUI builtins (Column, Row, ListItem, ...) as user function
definitions with 28% fabricated cross-file CALLS edges. This adds a
dedicated ArkTS grammar that keeps everything TypeScript already handles
and models the ArkTS syntax TS cannot parse.
Grammar (tools/tree-sitter-arkts/, generated parser vendored to
internal/cbm/vendored/grammars/arkts/, ABI 15 via tree-sitter-cli 0.25.10):
first-party derivative of tree-sitter/tree-sitter-typescript v0.23.2
@ 75b3874edb2d (the commit our vendored typescript/tsx come from) on the
tree-sitter-javascript v0.23.1 base @ 3a837b6f3658 (the version upstream's
package-lock pins). LICENSE carries the upstream MIT text verbatim plus a
derivative notice; the external scanner is a symbol-rename trampoline over
a byte-identical copy of the already-vendored typescript scanner header.
ArkTS additions: decorated struct component declarations with class-shaped
bodies; UI-DSL trailing-closure component calls with attribute chains after
the closing brace; decorators on function declarations (@Builder,
@Extend(T), @Styles); @Extend/@Styles leading-dot attribute-chain bodies;
anonymous stateStyles style blocks; import lazy named imports.
Wiring: CBM_LANG_ARKTS enum + lang spec (struct_declaration as a class
kind labeled Struct, public_field_definition fields), .ets extension,
LANG_NAMES/userconfig entries, grammar shim, and TS-family joins across
the extractors and the name-resolution guards (parse_es_imports, JS
keywords/test-file/func-kind/scope tables, TS heritage/param/receiver/
namespace/type-ref/channel/usage paths, js_ts_family and the weak-method-
match suppression). Field definitions now also carry their decorators, so
@State/@Prop/@Link members are findable with their roles.
Tests: grammar corpus (35 cases), per-language regression + label golden +
import net + extension cases, seven ArkTS extraction tests including the
phantom-builtin regression (ArkUI builtins must never be definitions), and
capability-ledger / call-node-manifest / call-argument-matrix rows. On the
14-file OpenHarmony sample corpus the TS-grammar baseline had 12/14 files
with parse errors (231 ERROR nodes); the arkts grammar parses 14/14 clean,
and an end-to-end index yields all 19 components as Struct nodes, 68
methods, 119 fields, and zero phantom builtin definitions.
