Fair value hierarchy (Level 1/2/3) classification and disclosures

Classify instruments into fair value hierarchy levels and draft disclosures.

Inputs:
- Instrument list and valuation methods: {instrument_list}
- Observable inputs used: {observable_inputs}
- Valuation adjustments (credit, liquidity): {valuation_adjustments}
- Transfers between levels: {level_transfers}
- Period: {period}

Output:
1) Classification table: instrument, valuation technique, key inputs, level, rationale.
2) Disclosure table templates (recurring/nonrecurring, rollforward for Level 3).
3) Control checklist (pricing sources, independent review).
4) Questions to resolve classification uncertainties.

Do not assign levels without describing the input observability basis.
