Primes¶
- Dissipation
- The processor erases one bit — overwrites it with a known reference value, irrespective of its prior state, as Bennett (2003) elaborated in showing that logical irreversibility necessarily incurs Landauer's minimum cost.
This sourceDefends and elaborates Landauer's principle, showing that logical irreversibility necessarily incurs the kT ln 2 minimum dissipation and clarifying its role in resolving the Maxwell's-demon paradox.

Bennett defends Landauer's principle: any logically irreversible operation such as erasing a bit must be paid for by an equal or greater entropy increase in the environment.
“the entropy decrease of the IBDF during a logically irre- versible operation must be compensated by an equal or greater entropy increase in the NIBDF and environment. This is Landauer's principle.”

- Downward Causation
This sourceReal paper, verified. NOTE: this is the WRONG Bennett for this prime — it is the physicist Charles H. Bennett on Landauer's principle, never cited in the body; the body's 'Bennett, K. (2003) ... ontological pluralism' refers to the philosopher Karen Bennett (see bennett-k-2003). This entry is an erroneous carry-over and supports no claim in the prime.
- Minimal Modification Principle
- It clarifies why some counterfactuals sound reasonable ("if I hadn't taken the job, I'd be living in my hometown") and others sound confused ("if I hadn't taken the job, I'd be living on the moon")—the second violates minimal modification by changing too much without justification, as Bennett (2003) elaborates in his comprehensive treatment of subjunctive conditionals.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 3 citations: 1 supported. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
