TTT Dogfood Phase 3: Full Algorithms in .t27 Assembly

Implementing complete algorithms in TRI-27 assembly (.t27) as part of the TTT (Trinity Third Transition) dogfooding process.

Completed

• ✅ Quick Sort — src/tri27/quicksort.t27

  • Lomuto partition scheme
  • In-place sorting
  • 5 comprehensive tests

• ✅ Binary Search — src/tri27/binary_search.t27

  • Divide-and-conquer search
  • Memory addresses 200-202 for low/high/mid

Key Learnings

1. 3-operand SUB: SUB dst, src1, src2 (not 2-operand)
2. JZ syntax: JZ reg, label (requires register operand)
3. No .const directives: Use immediate values directly
4. 15-bit immediate range: -16384 to +16383

Next Steps

• SHA-256 cryptographic primitive
• Huffman compression
• Dijkstra graph algorithm
• Matrix operations

Test Results

All 54 T27 program tests passing.
