## subsequent dependency gates
- [ ] concrete data models: required integer widths/conversions, records/tuples and construction, fields, enums, distinct/alias types, unions and matching. examples: `source/lexer/token.hon`, `source/sema/resolve.hon`, `std/mem/mem.hon`.
- [x] native integer widths (`i8`–`i64`, `u8`–`u64`, `isize`/`usize`) and checked explicit numeric conversions, including float truncation/range checks and integer-to-float rounding. preserve exact types through arrays, calls and range captures; retain strict implicit conversion rules.
- [ ] records/tuples and construction, fields, enums, distinct/alias types, unions and matching.
- [x] records/tuples, typed/contextual/anonymous construction, field defaults and reads/writes, nested aggregate value copies, imported record types and constructors through interpreter/native execution.
- [ ] enums, distinct/alias types, unions and matching.
- [ ] memory representation: source pointers/references, mutable and sentinel slices, optionals, layout/cast builtins and allocator-required libc calls. internal IR array addresses are not source pointers. examples: `std/mem/mem.hon`, `std/arraylist/arraylist.hon`.
- [ ] fallible results and cleanup: error-set composition, `try`/`catch`, `defer`/`errdefer`; infrastructure errors remain distinct from diagnostic traps. examples: `source/main.hon:41`, `source/sema/check/check.hon:117`.
- [ ] generic specialization and compile-time execution/reflection sufficient for existing `ArrayList`, hash maps, `enummap`, `meta` and `io.print`; include type/value parameters and compile-time generated storage.
