618-623: Clarify that these are word carries, not single-bit carries.
offset1.highandoffset2.highare propagated whole-word carries; they can be greater than1. The current wording reads like a boolean carry bit, which makes this arithmetic easier to misread later.🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed. In `@contracts/src/math/Uint128.compact` around lines 618 - 623, The comments incorrectly imply single-bit carries; update the explanatory comments around the multi-word add in Uint128.compact (referencing offset1, offset2, offset3 and their .high fields, and the toU128 calls combining ll.high, hl.low, lh.low, hh.low, hl.high, lh.high, hh.high) to state these are whole-word carries (i.e., full word values that can be >1) propagated to the next word, not boolean/single-bit carries, so readers understand offset1.high and offset2.high are multi-word carries.
623-627: Consider using direct comparison instead ofisZerofor clarity.Line 627 calls
isZero(offset3.high)whereoffset3.highisUint<64>, but this module definesisZeroonly forUint<128>andU128. While tests confirm the code works, the direct comparison is more explicit and avoids relying on any implicit type conversions.💡 Suggested improvement

Nitpick comments:
In `@contracts/src/math/Uint128.compact`:
- Around line 618-623: The comments incorrectly imply single-bit carries; update
the explanatory comments around the multi-word add in Uint128.compact
(referencing offset1, offset2, offset3 and their .high fields, and the toU128
calls combining ll.high, hl.low, lh.low, hh.low, hl.high, lh.high, hh.high) to
state these are whole-word carries (i.e., full word values that can be >1)
propagated to the next word, not boolean/single-bit carries, so readers
understand offset1.high and offset2.high are multi-word carries.
- Around line 623-627: The assert is calling isZero(offset3.high) where
offset3.high is a Uint<64> and isZero is defined for Uint<128>/U128; replace
that implicit call with an explicit comparison against zero to be clearer and
type-safe: change the assertion on offset3.high in the multiplication overflow
check (the assert that currently references isZero and offset3.high) to use a
direct equality check (offset3.high == 0) in the assert message for Uint128/U128
resultHigh/resultLow handling.
