نام	هدف
`Source`	Random-access source that can report independently available ranges
`Info`	Receives validated linearization offsets, range flags, status, and diagnostics

Returns True when a valid linearization dictionary was parsed, even if required ranges are still unavailable

The bounded header probe validates /L, /O, /E, /N, and /T
First-page readiness requires both the zero-based prefix through /E and a bounded look-behind range around the main xref offset
The method does not take ownership of Source
