# `zfin enrich`

Bootstrap a [`metadata.srf`](../config/metadata-srf.md) classification
file from public Wikidata + SEC EDGAR data.

```
Usage: zfin enrich [SYMBOL]
```

Requires `ZFIN_USER_EMAIL` (SEC EDGAR needs a contact address). Two
modes:

- **Portfolio mode** (no argument) -- classify every stock symbol in
  your portfolio and write a complete SRF file to stdout. Honors the
  global `-p` flag for file selection.
- **Symbol mode** (one `SYMBOL`) -- emit one appendable line for a
  single symbol.

## Sources

- **Wikidata SPARQL** -- sector / industry / country / asset class,
  plus a CIK lookup for the EDGAR call.
- **EDGAR XBRL company facts** -- shares outstanding, combined with the
  latest cached close to derive market-cap size buckets for US stocks.
- **EDGAR mutual-fund ticker map** -- fallback when Wikidata has no
  entry (open-end funds aren't exchange-listed); fills in
  `geo::US,asset_class::Fund`.

## Examples

```bash
zfin enrich > metadata.srf                # whole portfolio (default file)
zfin -p sample enrich > metadata.srf      # whole portfolio (named file)
zfin enrich AAPL >> metadata.srf          # append a single symbol
zfin enrich fagix >> metadata.srf         # symbol is auto-uppercased
```

Always review the output before saving -- symbols that miss both
sources come through as `TODO` lines to complete by hand.
