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.

Establishes reusable apparatus for asking: given scenario text X,
what structured initial decomposition does current production path produce?
- Direct curl/Postman via existing /api/cases/start route (no new API)
- Thin CJS helper at scripts/start-case-experiment-helper.cjs for Claude
experiments (imports startCase directly, zero code duplication)
- Zero-live-call verification: all four seam checks confirmed by existing
tests (cases-start-route.test.js, start-case-summary.test.js)
- No browser state, no persistence mutation, no Investigation ID required
by the route itself
Files:
+ scripts/start-case-experiment-helper.cjs (new helper script)
