Analyze {{artifact_path}} statically from these two observed formats:
- REMOTE HOST IDENTIFICATION HAS CHANGED
- Host key for %.200s has changed and you have requested strict checking.
Identify the function that passes the banner format to its logging/formatting
call, and the caller that owns the strict-checking diagnostic. Establish both
from real references, not guessed source names. Reuse one retained native
capture per selected function and selected structured facts.
For both functions, inspect the native recovered function prototype separately
from raw input varnodes. Report its parameter-entry count, each native parameter
index with storage/width, return descriptor including explicit void/type/storage
knowledge, native model label, lock state and recovery-error flags. The model
label and recovered entries are not a proven original ABI or source signature.
Keep explicit unknowns and native hidden/indirect-storage flags.
Count retained values marked is_input in each complete recovered graph. For
each native parameter storage tuple, determine whether an exact space/offset/
width match exists among those retained input values, preserving matched value
IDs and explicitly reporting missing matches. Do not treat missing retained
matches as proof that a source parameter is absent. Do the two inventories
mean the same thing? Can either count establish original source arity? Use
the observed facts to explain the distinction, without parsing a C declaration.
At the selected direct caller-to-banner-function call, show the target and the
passed pointer's recovered operand index, value identity, storage and width.
Relate that transfer to the callee's matching native parameter entry and its
first helper-call use. Keep the two snapshots' SSA identities separate; matching
storage is not cross-function SSA equality or a general alias proof. Verify
the selected pointer setup/call and callee helper use with focused machine
instructions, including actual call targets and passing registers.
Return a focused answer with real Evidence IDs, target digest and necessary
coverage. Distinguish native recovered model observations, storage-based
connections and machine corroboration from original signature/ABI/runtime
claims. Preserve unresolved stack rebasing, split/join/subregister mappings,
aliases, runtime binding and feasibility. Do not return complete C/graph reports
or execute the target. Close the target lease.
