Phasis now loads .ts and .tsx files through its existing APIs without a language flag or a runtime compiler. The PHP parser consumes erasable TypeScript syntax and retains executable JavaScript nodes; TSX uses the existing JSX lowering and renderer. .mts and .cts, module lookup, parsed-module caching, CLI AST output and PHP child execution also recognize typed files.

Explicit type-only imports and exports do not resolve their targets. Constructs requiring TypeScript runtime code generation report syntax errors. The supported boundary is documented in docs/typescript.md. Parse-cache identities distinguish JavaScript, TypeScript and TSX, including when the lower-level loader infers JSX options from a filename.

Validation:

• XDEBUG_MODE=off ./bin/verify-all: passed, 2,548 tests / 6,890 assertions, with two existing skips; static analysis, coding standards and all 16 oracle scenarios passed.
• Canonical test262 matrix: 53,616/53,616 passed, zero failures/skips/blocked/pending cases. The committed report's source identity matches this branch.
• Focused TypeScript/cache checks: 106 tests passed, including native Node/esbuild execution oracles, a 108-case assertion and side-effect matrix, existing JSX AST comparisons, malformed-input and directive tests, and both cache parse goals.
• JSX rendering, precompile and development/production hydration passed. The isolated Composer consumer passed on PHP 8.2 through 8.5.
• CI, Popular Packages, Web Platform Tests, dependency audit and documentation checks passed on the final implementation commit d5663bb.

Framework compatibility remains permanently local-only and was not run.
