-## Directives
-
-Directives are parser instructions that appear at the top of an SRF file. They
-use the `#!` prefix and must appear before any data records (except `#!eof`,
-which marks the end of data). Inline comments are allowed after directives.
-Unrecognized directives are silently ignored for forward compatibility.
-

-
-### `#!srfv1`
-
-Mandatory magic header that must appear on the very first line of every SRF
-file. Identifies the file format and version. A missing header causes a parse
-error; duplicates are also rejected.
-
-### `#!long`
-
-Selects long format mode where fields are delimited by newlines and records are
-separated by blank lines. Suitable for hand-edited configuration files. Mutually
-exclusive with `#!compact`.
-
-### `#!compact`
-
-Selects compact format mode where fields are delimited by commas and records are
-separated by newlines. This is the default format, so the directive is optional.
-Designed for machine generation where space efficiency matters.
-
-### `#!requireeof`
-
-When present, parsing will fail if the `#!eof` marker is not found at the end of
-the file. This is a corruption detection mechanism to ensure the file was not
-truncated during a write.
-
-### `#!eof`
-
-Marks the end of SRF data. Any data appearing after this directive causes a
-parse error. Can appear in the header (indicating an empty file) or after data
-records. Paired with `#!requireeof` for corruption detection.
-
-### `#!expires=<unix_timestamp>`
-
-Sets a cache expiration timestamp. The value is a Unix timestamp (seconds since
-epoch) as an `i64`. The `RecordIterator.isFresh()` method checks this against
-the current time. Data is always returned regardless of freshness -- callers
-decide whether to use stale data.
-
-```
-#!srfv1
-#!expires=1772589213
-key::cached_value
-```
-
-### `#!created=<unix_timestamp>`
-
-Records when the data was created. The value is a Unix timestamp as an `i64`.
-This is metadata only -- the library tracks it but takes no action on it.
-Available on the iterator/parsed result immediately after construction.
-
-### `#!modified=<unix_timestamp>`
-
-Records when the data was last modified. The value is a Unix timestamp as an
-`i64`. Like `#!created`, this is metadata only and is available on the
-iterator/parsed result after construction.
-
-### Example with multiple directives
-
-```
-#!srfv1
-#!requireeof
-#!long
-#!expires=1772589213
-#!created=1772500000
-name::alice
-age:num:30
-
-name::bob
-age:num:25
-#!eof
