## Answer

VERDICT: PASS

Both blockers are resolved and Risk-C remediation is accepted.

Blocker #1 is fixed: .d.mts is the correct declaration strategy for .mts/.mjs ESM conversion paths; TypeScript documents .mts -> .mjs and corresponding declarations as .d.mts. 
TypeScript

Blocker #2 is fixed: the graph checker now covers the relevant static import forms, side-effect imports, export-from forms, and string-literal dynamic imports; excluding template/runtime-built specifiers is acceptable for this migration graph scope. MDN’s import/export syntax confirms those specifier-bearing forms, and dynamic import() permits computed specifiers, supporting the explicit out-of-scope note.

Risk-C accepted: deferring errors.mjs and proving the .ts + sibling .d.mts path on low-fan-in leaves before touching the 19-importer hub is a sound blast-radius reduction. Reported HEAD gates are green, manifest unchanged, graph regenerated, zero cycles.

No remaining blockers.
