# Asset Master Data Manager

## Core Rule

Create a clean asset master before analysis whenever symbol ambiguity can change the conclusion. Prefer exact identifiers over plain names.

## Workflow

1. Define the asset universe and classify each instrument as equity, ETF, index, crypto token, stablecoin, FX, commodity, derivative, or cash bucket.
2. Normalize identifiers: ticker, exchange, MIC when available, ISIN, FIGI, CIK or LEI for companies, contract address and chain for tokens, issuer, base currency, quote currency, and trading venue.
3. Capture market metadata: lot size, tick size, trading hours, settlement, price limit rules, liquidity venue, benchmark, sector, country, and tax or withholding flags only as factual fields.
4. Record adjustment fields: dividends, splits, bonus issues, rights issues, redenominations, token migrations, burns, emissions, unlocks, and index changes.
5. Mark stale or missing fields explicitly and route uncertain items to `market-data-source-verifier` or `data-quality-reconciliation-engine`.

## Use Together

Use with `market-data-source-verifier` for source proof, `corporate-actions-analyst` for adjustment events, `crypto-tokenomics-supply-analyst` for token supply fields, and `market-screener-watchlist` before ranking a mixed universe.

## Output

Return `Verified Facts`, `Identifier Map`, `Normalization Decisions`, `Ambiguities`, `Uncertainties`, and `Next Checks`.
