# Deep Research Antigravity Rule

When operating this repository from Google Antigravity, use Antigravity as the primary Deep Research executor and use the repository as the method, artifact, and validation framework.

## Non-Negotiables

- Use Antigravity's model quota for main research work.
- Do not default to Python core model-worker commands such as `run`, `research --execute-packets`, or `research --assemble-chapters`, because they may route work through ZenMux/API credits.
- It is acceptable to write phase artifacts directly in Antigravity when following the project skills and evidence schema.
- Use `.agents/skills/antigravity-surface-adapter/SKILL.md` whenever the user asks for Antigravity usage, phase execution, model planning, or quota planning.
- Keep all research outputs under `projects/<slug>/`.
- Use Python scripts only for scaffolding, deterministic checks, citation/report rendering, status, and local material processing unless the user explicitly approves external model/API usage.

## Anti-Hallucination Contract

- No tool receipt, no search claim. The agent may not write that it has searched, checked, verified, or confirmed anything unless a search/browser/terminal/MCP tool call actually happened and the result is logged.
- No source ID, no factual claim. Every concrete fact in drafts must map to a `source_id` in `sources.jsonl` or the current phase ledger.
- No snippet laundering. Search result snippets, AI summaries, and memory are only leads; they cannot support final claims.
- Failed access must be explicit. If a page, PDF, registry, patent, or filing cannot be opened, mark it as inaccessible and do not quote exact values from it.
- Each phase must maintain `phaseX/search_log.md` or `phaseX/search_log.jsonl`.
- Each evidence packet must include `search_receipts`, `sources`, `counter_evidence`, and `unsupported_claims`.
- When evidence is thin, write "该观点证据不足，待进一步验证" rather than smoothing over the gap.

## Quota Discipline

- Surface manager: Gemini 3 Flash.
- Phase 0-1: Claude Opus 4.6 (Thinking).
- Phase 2: Gemini 3.1 Pro (Low).
- Phase 3: Gemini 3.1 Pro (High), with fallback to another model only if quality is inadequate.
- Phase 4: Claude Opus 4.6 (Thinking).

## Pause Points

Pause after Phase 1 and Phase 3. Ask the user to confirm the framework or critique decision before moving to the next major phase.
