DeepSeekDSH fixture validation record
Date: 2026-09-30
Scope: exercise generator and reference repair only; NOT a DSH/model benchmark.
Environment: Node.js v22.16.0, Linux container.
Generator SHA-256: eafec299997732c81db5e6f9a96ceaf67aa4ccb27fe1e0268712d4c6b765a005

1. node create-cart-task.mjs
   Created a new dsh-cart-task folder, exit 0.
2. node --test dsh-cart-task/cart.test.mjs
   10 tests: 6 pass, 4 fail, 0 skipped. Exit 1, as designed.
3. node create-cart-task.mjs (same directory)
   Refused to overwrite the existing folder. Exit 1.
4. In a SEPARATE reference copy, changed only:
   const lineTotal = unitPriceCents;
   to:
   const lineTotal = unitPriceCents * quantity;
5. node --test reference-check/cart.test.mjs
   10 tests: 10 pass, 0 fail, 0 skipped. Exit 0.

No DSH installation or model session was used. No API credentials or paid calls
were used. API costs, model speed and model success rates were not measured.
This tiny fixture checks the recording workflow and is not a model ranking.
The reference correction should not be supplied to a model during an evaluation.
