Adds experimental apparatus for testing whether removing the question field
from importantUnknowns in reconstruction output improves semantic fidelity.
New files:
- lib/reconstruction/schema-variant.js (conditionB schema + production passthrough)
- prompts/reconstruct-v0.5-b-noreq.md (alt prompt, identical line count to prod)
Changed files:
- lib/graph/orchestrator.js (pass generationSchema through dependencies)
- lib/analysis.js (accept opts.generationSchema fallback to original schema)
- scripts/start-case-experiment-helper.cjs (--condition B/A flag support)
- tests/scripts/start-case-experiment-helper.test.js (8 new deterministic tests)
43 targeted deterministic tests PASS. Production callers use original prompt/schema unchanged.
No live model calls. No full suite evidence available.

Add explicit reasoning guidance for normalising counts by exposure/denominator,
distinguishing total count from rate, and avoiding correlation-as-causation errors.
Changes:
- prompts/reconstruct-v0.3.md: new prompt with normalisation discipline
- lib/reconstruction/prompt.js: v0.3 loader + env var override support
- lib/analysis.js: defer DEFAULT_PROMPT_VERSION to prompt module (defaults to v0.3)
- PROMPT_VERSIONS extended to [v0.1, v0.2, v0.3]
- tests/v03-reasoning.test.js: 34 focused tests covering prompt loading, schema validation, guidance completeness, and target scenario fixture
- playwright.config.js + tests/smoke.test.js: minimal UI smoke test for browser rendering
- package.json: add @playwright/test as devDependency
Default switches to v0.3; v0.2 selectable via promptVersion or RECONSTRUCTION_PROMPT_VERSION env var.
