Landing the first province sample of the rules/_evidence/ tree.
Locks down the hunan-2026 本科批 院校专业组 rule set so audit
output and downstream consumers can cite the source摘录 instead
of just 'trust me, the loader says so'.
What's in the box:
- rules/_evidence/README.md: directory contract, evidence-file
template (4 required sections), coverage table, and a note on
RuleLoader's future strict_evidence toggle.
- rules/_evidence/hunan/<11 rule keys>.md: one Markdown
摘录 per source_evidence_id declared in hunan.yaml
(mode / batch / max_volunteers / max_majors_per_group /
has_adjustment / adjustment_scope / retrieval_rule /
collection_count / subject_mode / official_url /
exam_subject_total). Each file carries the official quote,
the machine-readable YAML form, key edge cases, and the
next-review date.
- tests/test_rules_evidence_layer.py: 4 invariants
* README exists and documents the contract
* every active hunan.yaml source_evidence_id has a matching
.md file
* 11 evidence files contain the keywords that prove they
actually carry the rule (parameterised, one test per file)
* every evidence file has all 4 required template sections
* no orphan evidence files (file exists but no rule
references it)
Verification:
- focused: 27 passed (15 evidence-layer + 12 cli doctor)
- dev-verify full gate: all checks passed (ruff / mypy /
coverage / pytest / benchmark)
Follow-up (not in this commit):
- Wire RuleLoader.from_truth_root(strict_evidence=True) so
callers can opt in to fail-loud on missing evidence
- Extend the same pattern to national.yaml + 2-3 more
provinces
- Add a 'last_verified_at' field to each rule and surface
>90-day-old evidence via 'gaokao-cli rules status'
