Characterizing provability in BI’s pointer logic through resource graphs
Bibliographic record
Abstract
Abstract We propose a characterization of provability in BI's Pointer Logic (PL)that is based on semantic structures called resource graphs. This logic has been defined for reasoning about mutable data structures and results about models andverification have been already provided. Here, we define resource graphs that capture PL models by considering heaps as resources and by using a labellingprocess. We study provability in PL from a new calculus that builds such graphs from which proofs or countermodels can be generated. Properties of soundnessand completeness are proved and the countermodel generation is studied. 1 Introduction Separation logics are logics for reasoning about mutable data structures in which thepre- and postconditions are written in a logic enriched with specific forms of conjunction or implication. In this context, Reynolds has proposed an intuitionistic logic ex-tended with a separation connective \\Lambda [12] and Ishtiaq and O'Hearn have investigatedthe same approach from the point of view of the logic of Bunched Implications (BI)

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
