Truth Bear — Cross-Line Cascade & Leading Signals for AI Agents (GAUGE engine)

Pay-per-call signals for AI agents via x402 (USDC on Base, no API key). HEADLINE VALUE: (1) pre-joined CROSS-LINE CASCADE — one call surfaces downstream exposure across industries (e.g. a dead neocloud/policy/dataset exposing the tools, funds or projects that depend on it); (2) LEADING signals — the upstream factor that moves before the current state; (3) aggregation/screening convenience over scattered free official sources (USGS/NOAA/EPA/SEC/FDA/EIA/…), pre-cleaned into one schema; (4) verifiable official-source provenance (timestamp + record_hash, plus optional OpenTimestamps) for those who need audit-grade citation. Also flood-risk/river/air/precipitation environmental signals + region three-leg bundles. Pure description, no judgment/prediction. Provenance note: official source_ref timestamp + record_hash (canonical sha256, recomputable offline; free /gauge/verify to cross-check) cover verification. Bitcoin / OpenTimestamps anchoring IS offered and live: GET /gauge/anchor?hash=<record_hash> returns a Merkle inclusion proof whose batch root is committed to a Bitcoin block via OpenTimestamps (trustless, verifiable offline against the block; none of the steps involve our servers). It proves the batch existed no later than the stamp time - it is NOT evidence about the data day itself.
