- **Constraints / validation**: `bool`.
- **Description**: Allows fallback from ME mode to direct DC when ME startup fails.
- **Description**: Allows Direct-DC fallback when ME is unavailable. With `use_middle_proxy = true`, startup opens Direct-DC routing first and moves new sessions to ME after ME readiness is observed.

## me2dc_fast

- **Description**: Fast ME->Direct fallback mode for new sessions after ME was ready at least once. Initial direct-first startup fallback is controlled by `me2dc_fallback`.

## exclusive_mask
- **Constraints / validation**: TOML map. Keys must be SNI domain names. Values must be `host:port` with `port > 0`; IPv6 literals must be bracketed.
- **Description**: Per-SNI TCP mask targets for fallback traffic. When a TLS ClientHello SNI matches a key, Telemt relays that unauthenticated connection to the mapped target. Other fallback traffic keeps using the existing `mask_host`/`mask_port` or SNI-aware default masking behavior.
- **Example**:
```toml
[censorship]
tls_domains = ["petrovich.ru", "bsi.bund.de", "telekom.com"]
[censorship.exclusive_mask]
"bsi.bund.de" = "127.0.0.1:443"
```
## mask_unix_sock
- **Constraints / validation**: `String` (optional).
- Must not be empty when set.
