Six answers per instrument.

Layer 01 — Two engines, one workbook

A static front half and an intelligent back half.

The panel is deliberately hybrid. The front half preserves the original static Volatility Control Panel: durable instrument characteristics — session overlap, range rank, spread and slippage caution — assign each symbol to a volatility bucket, and the bucket returns baseline ATR trailing coefficients per timeframe. The back half is the Volatility Intelligence Engine (VIE), which adds live volatility evidence, higher-timeframe authority context, and an authority-adjusted coefficient ladder. The audit tabs at the end connect both halves into one operating loop.

Layer 02 — The four coefficient objects

One decision, four numbers that must be kept distinct.

The workbook keeps four coefficient ideas visible at once, because collapsing them is how coefficient decisions stop being auditable:

• Static Lookup Coefficient — from Instrument_Master and Coefficient_Lookups, by bucket and timeframe. Trust it when live evidence is incomplete or unclear.
• Base VIE Coefficient — the live evidence score mapped to an asset-aware tier ladder at the trigger timeframe.
• Authority-Adjusted VIE Coefficient — the base plus the higher-timeframe authority add-on, when structure justifies extra breathing room.
• Final Coefficient Used — the manual audit-log entry recording what was actually deployed: static, VIE, or a documented discretionary override.

Layer 03 — The evidence engine

What the intelligence score is made of.

The VIE_Coefficient_Model blends four scored components into a final intelligence score: a Bollinger composite (band width, persistence, expansion, slope, displacement), an ATR composite (ratio, strength, direction), higher-timeframe confirmation (agreement is strongest; conflict cuts confidence), and risk pressure (news and spread/slippage conditions that should make widening less automatic, not more). The score resolves to an intelligence tier — Compression, Stable, Expansion, and beyond — and the tier selects the base VIE coefficient row.

Layer 04 — Answer freshness

Six answers, each stamped with its data window.

Every reading the panel serves carries its computation window — because a volatility answer without a timestamp is a rumor. The stamping discipline lets consumers judge staleness at a glance and lets the Saturday review verify that no downstream decision quoted an answer older than its doctrine permits.
