The semantic reason is that “developable due to ” and “developable due to ” answer different causal

attribution questions. 
A.4 IH as a source-sensitive relation 
A useful semantic representation is 
 
𝐼𝐻𝑆
( ) = ⟨𝑝𝑟𝑜𝑗𝑒𝑐𝑡𝑒𝑑 𝑐𝑜𝑛𝑡𝑒𝑛𝑡 𝑜𝑓 𝑆,  𝑠𝑜𝑢𝑟𝑐𝑒= 𝑆,  𝑑𝑒𝑝𝑡ℎ+ 1⟩.
This notation is explanatory, not a literal set-theoretic definition. Its purpose is to make three facts obvious: 
1.​
inherited content projects to source content; 
2.​
source identity remains recorded; 
3.​
an additional IH application increments depth. 
A.5 Projection function 
Define recursively: 
 
π 𝑃𝐴φ
( )
(
) = 𝑃𝐴φ
( ),
 
π ¬𝑆
(
) = ¬π 𝑆
( ),
 
π 𝑆∧𝑇
(
) = π 𝑆
( ) ∧π 𝑇
( ),
 
π 𝑆∨𝑇
(
) = π 𝑆
( ) ∨π 𝑇
( ),
 
π 𝐼𝐻𝑆
( )
(
) = π 𝑆
( ).
Projection is useful for ordinary entailment. It is deliberately lossy: it throws away provenance. 
A.6 Why projection alone saturates but the full state need not 
If one repeatedly projects higher stages, many later non-opposite-stage statements can become logically 
weak or redundant. This is expected. The full hierarchy is not defined solely by . 
π
For example, 
πIH¬SM2=¬SM2, 
while 
πIH¬SM20=¬SM20. 
The projected formulas may stand in implication relations. Their full inherited states still differ by source and 
depth. 
A.7 A provenance graph 
Represent each higher stage as a directed acyclic graph. 
For SF3: 
•​
root: SF3; 
•​
child 1: IHSF2; 
•​
child 2: IH¬SM2; 
•​
the SF2 source points to its four canonical components; 
•​
the SM2 source points to its four canonical components. 
The graph is not a mere display convenience. It is the data structure that preserves what Boolean flattening 
would erase.
