Extreme UV Index (11.0) Across Mexico — Contact-Center & Knowledge-Worker Operations Footprint at Risk

A UV Index of 11.0 has been recorded across Mexico, placing the country in the 'Extreme' exposure band. With approximately 3.7 million contact-center, back-office, and knowledge-worker seats concentrated in Mexico City, Guadalajara, and Monterrey, outdoor commutes, field staff, and facilities lacking adequate cooling or shade infrastructure face meaningful health and attendance risk. Operations leaders should monitor absenteeism trends, assess site HVAC adequacy, and consider shift-timing or transport advisories for affected hubs.

Why declaredmergeDeterministic
Incident dedup / merge keys (entity, episode, network, region+title)v4
Checked in order against open same-domain incidents (never an aggregate-titled bucket): (1) ENTITY key, region-independent, incident active <14d (updated_at): shared CVE id, OR (cyber) >=2 shared distinctive vendor/product tokens (1 suffices when it carries a digit, i.e. a product model), OR (travel, agents-039) same travel operator/system key (travelSystemKey — airline/ATC/GDS/rail identity with a disruption cue), OR same network/AS key (agents-022). (2) EPISODE key (weather/environmental/disaster + travel per agents-039 + environmental air-quality per agents-040), incident active <7d: same hazard family (weather: heat/tornado/flood/cyclone/winter/wildfire/storm; travel: strike/ground_stop/airspace/it_outage/transit; environmental air-quality: air_quality/smoke — a multi-day wildfire-smoke wave, split cleanly from the weather wildfire FIRE family) AND same macro-region (eu | us/<census region> | country code) — a multi-day strike series, rolling ground stop, or smoke wave refreshes ONE incident, not dailies. (3) Legacy region-overlap + title-word dedup, active <24h (v5 unchanged). Merge unions affected_regions + related_signal_ids + material_event_keys, bumps event_count, renders the merged regions into the description ("Affected regions:" trailer), logs stage=declare decision=merge (engine deterministic), and unions the evidence projection’s signal sources. agents-046 (v4): a merge advances the material clock (last_material_event_at) ONLY when it brings GENUINELY-NEW material event keys (newMaterialKeys over the incident's material_event_keys, agents-010 Fault B) — an EVOLVING situation. Re-emission / continued press coverage of already-tracked events accumulates ids/regions/event_count but HOLDS the material clock (agents-019 §C), so a wallpaper advisory's quiet clock can finally elapse toward close. This is the evolving-vs-wallpaper discriminator the earned-rights lifecycle backstop (incident_lifecycle v1) reads.

Why SEV3SEV3score 3Deterministic
Incident severity level (SEV1–SEV4) at declarationv5
agents-043 (v4): a Gate A workforce-footprint declaration (geoExposureFloor) is scored on VALUE = magnitude × footprint via workforceFootprintSeverity, NOT the base mapSevLevel: catastrophic (sev>=9) × MAJOR hub (bpo>=3) → SEV1 (the Manila 7.0-quake worked example — this deliberately supersedes the single-event cap per ALERTING-PHILOSOPHY.md / Ted's criteria); sev>=9 × moderate hub (bpo==2) → SEV2; sev>=8 × bpo>=2 → SEV3. SEV1/SEV2 remain human-gated at declaration (validation pending). Every other path keeps the base mapSevLevel below unchanged. agents-046 (v5): the named-tropical-system active-threat arm (workforceFootprintSeverity tropicalActiveThreat, sev 7–7.99 × bpo>=2) → SEV3 — a tracked storm approaching a footprint coast is a genuine 0–72h disruption a WFM leader pre-positions for (same SEV3 honesty as the acute-severe-weather floor). The flag is a no-op for sev>=8 (those hit the higher branches), so hurricanes are unaffected. Base: SEV2 if sev>=9 AND news>=2 AND bpo>=1; else SEV3 if sev>=8 AND (news>=1 OR bpo>=1); else SEV4. Acute severe-weather (agents-028): if sev>=9 floor to SEV3 (SEV2→SEV3); minor/transient watches+advisories drop SEV2/SEV3→SEV4. Single-event cap: any SEV2 caps to SEV3 absent sustained multi-day BPO-region corroboration (SEV2 promotion is human-gated via revalidation). Systemic-travel floor (agents-039): a travelSystemicFloor declaration (multi-signal aggregate on member-relevant geography, sev 6-7 by design) floors SEV4→SEV3 — a region-level operational disruption, same honesty argument as the acute-weather SEV3 floor. It never raises anything to SEV2: SEV2 keeps its base intensity+news+human gating. Environmental air-quality floor (agents-040): an enviroAirQualityFloor declaration (multi-city cumulative air-quality/smoke aggregate on member-relevant geography, sev 6-7 by design) likewise floors SEV4→SEV3, and never raises anything to SEV2. score = numeric SEV (1=most severe … 4); SEV3/SEV4 auto-validate, SEV1/SEV2 require human validation.
