gndc - Stage 6 - Assemble & validate

[thejhh]

1. Concatenate the generated .gnd snippets in logical order (load-inputs, compute-checksum, format-result, main).

2. Run a static validator (regex or parser) to check:

   • single-assignment, valid opcodes, balanced _ flow, ends with exit.

3. If validation fails, send the offending snippet back to Stage 5 with an error message and ask for correction.
