Dependency rules read framework JS/TS config aliases and accept consumer-provided package mappings. externalAlias and externalDependencies describe runtime imports; externalPackages maps packages to stdlib paths and major versions. Public fixtures use generic example packages.

Adding owned mapping buffers exposed per-file copies of the full configuration through semantic passes. Internal passes now borrow the configuration, copying only when file-dependent defaults need adjustment. Public APIs and buffer capacities remain unchanged.

Validation: Zig 0.17.0 full suite passed (2333 tests and 91 rule snapshots); native release build passed. Regression cases cover mapping validation, configuration reuse, Jest detection, declaration-file namespaces and both IO paths for operand checking.

Local native comparison, same 1000-file corpus / 30 statement blocks, release-fast builds, 5 warmups and 21 interleaved samples per binary (median):

Rules	Main baseline	Before copy fix	Current head
Shared rules	50.00 ms	53.41 ms	32.24 ms
Basic-only control	26.87 ms	26.93 ms	24.12 ms
Semantic-only control	45.61 ms	49.60 ms	28.88 ms

Current-head Node.js 20/24 and WebAssembly CI passed. CodSpeed also passed: the shared native benchmark improved from 592.1 ms to 269.4 ms (2.2x efficiency), with three improved benchmarks and two unchanged.
