SIGNATURE / CONSTRAINT OPTIMIZATION / FIT V1.0

Make this file
fit the rule.

Start with the constraint, not the codec. FIT looks at the file and the ceiling, then chooses a verified local strategy instead of making you hunt for the right compressor.

Tell FIT what
the file must obey.

Start with the upload limit. FIT decides whether the source needs no change, image constraint search, archive repack, or a different verified writer.

IMAGEZIPPDF AWAREOTHER / ROUTE
01 / INTENTThe limit is the interface.

Tell FIT what the destination accepts. It decides which engine, if any, can satisfy that rule safely.

02 / SOLVEImages use real constraint search.

Dimensions, format and encoder quality are searched locally. EXACT remains available when you want the expert controls.

03 / PACKAGEZIP is audited before repack.

Entries are inspected and CRC-verified before FIT rebuilds the container. Unsafe or ambiguous packages are routed to UNPACK instead.

04 / HONESTYNo fake universal compressor.

PDF and unsupported formats are never rewritten blindly. FIT names the missing writer and preserves the source untouched.
