Default codec + quality settings.

Fields

text_codec: String

binary_codec: String

metadata_codec: String

metadata_quality: u8

metadata_externalize_threshold: usize

Compressed-metadata size (bytes) above which the blob is externalized to a metadata.bin sidecar instead of inlined in the manifest. Default: just under the reader’s 1 MiB inline ceiling (DEFAULT_INLINE_METADATA_MAX_BYTES); raise to that ceiling for maximally self-contained images, lower it to keep manifests small. See limnifs#187.

shared_inline: bool

Dedup identical inline file contents into the shared-inline table (issue #189). Default ; set to emit plain inline inodes readable by pre-#186 readers (cached tebako runtimes whose reserved mask rejects the SHARED_INLINE flag).

seekable_drops: bool

Emit large general-codec drops (> 1 MiB plaintext) as seekable containers (256 KiB independent frames; bounded random reads). Default true. Set false for maximum compression ratio — frames give up cross-frame context (~1-3%) and windowed reads pay a full-drop decode again.

max_drop_size: u32

Maximum plaintext size (bytes) of a drop the writer may emit from a whole-file path (categorizer claims and the whole-file fallback). Files larger than the cap fall back to FastCDC chunking + tournament so every drop’s decode cost is bounded by construction (EROFS fixed-output pclusters). Default 4 MiB; 0 = unlimited (pre-knob behavior). The skip_chunking (max-write) profile is exempt — whole-file IS its speed contract.

inline_threshold: u16

Inline data threshold (bytes).
