evidence-first-claimslisted

Record sources, evidence, hypotheses, results and claims in a ScientistOS research graph at the E0-E5 evidence level the lineage actually supports, and split work between the Scientist and Auditor roles. Use before asserting any scientific finding, citing a paper, or saying something "shows" or "causes" or "improves" something, and when promoting a claim, writing an abstract or results section, or auditing someone else's conclusion. Triggers include "record this finding", "add this evidence", "is this claim supported", "can we say X causes Y", "write up the results", "what level is this claim", "check for confounding or leakage". Do not use for non-scientific assertions or projects without a ScientistOS research graph.

# Evidence-first claims Say in one short line that you are using the `evidence-first-claims` skill before you act, so the user can see which discipline you are working under. A claim is only as strong as the lineage attached to it. The engine enforces this in code, so an unsupported claim raises `ValueError` rather than quietly passing. The CLI has no command for evidence or claims. Use the MCP tools `add_source`, `add_evidence`, `register_hypothesis`, `add_assumption` and `register_claim`. They validate arguments and return contract failures as readable errors. The Python API below is the fallback when the tools are unavailable or you need something they do not expose. Run the Python API with the interpreter that has `scientistos` installed, which is the project venv (`.venv/bin/python`). A system `python3` will not have it importable. `ResearchEngine(Path("research.db"))` resolves relative to the current directory, so `cd` into the project that owns the graph, or pass an absolute path. Do not create a new graph in whatever directory you happen to be in. ## The evidence ladder Enforced in `ResearchEngine._validate_claim_evidence` (`src/scientistos/engine.py:191`): | Level | What it requires | |---|---| | E0 | Nothing. Unsupported statement, speculation. | | E1 | At least one evidence record or result, and every attached evidence must pass all four verification flags. | | E2 | Everything above, plus at least one `result_id`. Empirical claims need empirical results. | |
