### `compute_altman_z_score`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Compute the Altman Z-Score (public-company, non-financial-services version) for a US-listed ticker -- a quick bankruptcy-risk / financial-distress screen from five balance-sheet ratios. Looks up working capital, total assets, retained earnings, EBIT, market cap, total liabilities, and revenue from SEC EDGAR + market data automatically -- just pass a ticker. Returns the score and which zone it falls in: safe (>2.99), grey (1.81-2.99), or distress (<1.81).
```
