    • Analyst Notes

    Severe weather presents varied, localized disruptions across key corridors. Flash Flood Warnings in Texas necessitate immediate caution for ground transport and potential border delays. Meanwhile, the Mountain West faces operational hazards from Red Flag conditions in Colorado and Fire Weather Watches in South Dakota, impacting visibility and safety. Operators in Alaska must anticipate reduced visibility and handling challenges due to the Heavy Freezing Spray Warning.

    Why It Matters

    Analyst summary available

    Claim Policy

    Cited report/packet claims only

    Use cited packet/report evidence for claims; weather, road, policy, and map overlap stays contextual unless evidence proves causality.

    Packet or replay citations must expose evidenceId, claimBearing, claimGuidance, evidenceMode, and source_ref claim policy.

    Broad source-level claims also require sourceClaimAudit review, /v1/sources claimBearing=true, sourceFactHealth.total > 0, sourceFactHealth.claimBearingPolicyRows > 0, sourceFactHealth.parserLagHours within maxParserLagHours, sourceFactHealth.futureEventsBeyond7d=0 for current road claims, no pending/failed embedding backlog for semantic-only claims, no degraded-run caveats, and no blocking claimWarnings for the source family.

    Raw-current, raw-only, stale, no-row, scheduled, planned, future, retired, unknown, parser-lagged, degraded-run, embedding-backlog, feed, search, and briefing source rows remain caveated context unless report citations explicitly review them.

    Planned/future traffic rows must be labeled non-current planning context and not cited as current evidence.

    Model Generation Policy

    modelProvider/modelVersion: local / gemma4:e4b

    Lane: local_report_generation

    OpenAI content/report lanes require explicit gates and use store:false; no-call previews write local artifacts only.

    Generated reports inherit cited report text, source facts, packet evidence, saved source_ref claim policy, and /v1/sources source-fact health: sourceFactHealth.total > 0, sourceFactHealth.claimBearingPolicyRows > 0, parser-lag/future-row/embedding-backlog/degraded-run checks, and no blocking claimWarnings.

    Generated report wording is reusable only inside cited report text, cited packet evidence, or saved source_ref claim policy.

    Broad source-level claims require sourceClaimAudit review, /v1/sources claimBearing=true, sourceFactHealth.total > 0, sourceFactHealth.claimBearingPolicyRows > 0, sourceFactHealth.parserLagHours within maxParserLagHours, sourceFactHealth.futureEventsBeyond7d=0 for current road claims, no pending/failed embedding backlog for semantic-only claims, no degraded-run caveats, and no blocking claimWarnings.

    Raw-current, stale, no-row, scheduled, planned, retired, unknown, planned/future, parser-lagged, parser-incomplete, degraded-run, and embedding-backlog rows remain context only unless cited evidence says otherwise.

    Do not infer causality from co-occurrence; weather, road, policy, and wait overlap stay contextual unless evidence proves cause.
