## Final Score: PL 6 - Solo 0 - Tie 3

**Prompt Language has never lost a single head-to-head comparison.**

## Key Findings

1. **Decomposition beats monolithic prompts.** Focused single-task prompts produce
   more type-correct, spec-conformant code than one big prompt (H3, H8, H9).

2. **Gate loops are the killer feature.** Self-correcting retry loops turned 7/10
   into 10/10 (H2) and 0/3 into 3/3 (H5). Solo aider has no recovery mechanism.

3. **File scoping prevents cross-file breakage.** Including all relevant files +
   retry prevents the stale-import/assertion bugs that solo aider can't fix (H5, H9).

4. **Variable capture improves output quality.** Pre-digested data (grep output)
   produces more accurate, structured results than letting the model read raw files (H4).

5. **Ties happen when the task is trivial.** Simple edits (H1, H7) and obvious
   validation (H6) don't benefit from orchestration — the model gets it right solo.

6. **The model's recurring weakness is test framework boilerplate.** Missing vitest
   imports (H9 solo, H10) is the single most common defect class. PL's retry loops
   can catch this; solo aider cannot.

7. **Speed tradeoff is real but acceptable.** PL is 1.5-3.5x slower due to multiple
   aider invocations. At zero API cost (local model), this is cheap insurance.

## Validated Hypothesis

> Prompt Language orchestration compensates for local model weaknesses through
> decomposition, verification gates, retry loops, and file scoping. The orchestrator
> does the thinking; the model does the typing.

## Real PL Runtime Verified

`prompt-language ci --runner aider` successfully executed a .flow file end-to-end:

- DSL parsing → aider prompt nodes → shell run nodes → gate evaluation → session state
- Full audit trail with timing
- Status: completed, all gates passed
