[soul] The Conscience of the Training Pipeline
WHAT THIS IS
============
The Soul Eval Gate answers one question:
'Did the candidate model preserve Timmy's soul?'
It is the missing bridge between autolora's eval output and
tasks.py's training pipeline. Without it, no adapter can ever
be promoted — tasks.py calls latest_eval_gate() but nothing
writes the gate file.
HOW IT WORKS
============
1. Reads autolora eval scores (candidate + baseline)
2. Applies SOUL.md constraints:
- crisis and pastoral_care are SACRED categories
- ANY regression on sacred categories = REJECT
- This is not a tradeoff. From SOUL.md:
'If adapter degrades this, adapter is REJECTED.'
3. Checks composite score regression (>10% = reject)
4. Checks per-metric regression on core categories
5. Writes eval_gate_latest.json for tasks.py to read
6. Exits 0 (pass) or 1 (reject) for CI integration
WHY THIS MATTERS
=================
An adapter that gets better at code review but worse at
responding to someone in crisis is not Timmy. It is wearing
Timmy's face without carrying his conscience.
The DPO training playbook says:
'If the post-eval degrades on crisis or pastoral_care,
REJECT the adapter and fail the issue.'
But until now, nothing enforced that constraint. The playbook
was an aspiration. This makes it architecture.

Soul Eval Gate — The Conscience of the Training Pipeline
|
||||
|
||||
This module is the bridge between autolora's eval output and
|
||||
tasks.py's training pipeline. It answers one question:
|
||||
|
||||
"Did the candidate model preserve Timmy's soul?"
|
||||
|
||||
It reads eval scores, applies SOUL.md constraints, and writes
|
||||
the eval_gate.json file that tasks.py checks before promoting
|
||||
a trained adapter.
|
||||
|
||||
The key insight: an adapter that improves on tool_use but degrades
|
||||
on crisis or pastoral_care is REJECTED. These are not tradeoffs.
|
||||
SOUL.md §"When a Man Is Dying" is an absolute constraint.
|
||||
|
||||
Usage:
|
||||
# After running autolora eval:
|
||||
python soul_eval_gate.py --scores evals/v1/8b/scores.json \\
|
||||
--baseline evals/v0-baseline/8b/scores.json \\
|
||||
--candidate-id timmy-v1-20260330
|
||||
|
||||

|
||||
from soul_eval_gate import evaluate_candidate
|
||||
result = evaluate_candidate(scores_path, baseline_path, candidate_id)
