Evidence contract — Cue

Result contract v1. Locators: timestamp_ms, stream indices, subtitle cue ranges, source hash. Gaps: missing ffprobe, absent subtitles, optional ASR unavailable. No evidence_first tool.

Implemented family wire fields (v1)

Every tool result includes:

• envelope_version: "1"
• status, tool, product, product_version
• route as { engine, path? }
• warnings and gaps arrays (may be empty)
• domain payload (often also as top-level twin/results/answer for compatibility)
