Abstract

fetched live from OpenAlex

The conventional model of a file as a contiguous array of bytes hides information about the physical location of data from users. While this simplifying abstraction can be useful in some cases, it can also lead to suboptimal performance and unnecessary overhead. A growing number of applications – even those as basic as the Unix cp utility – can benefit from increased access to file system metadata. We present MapFS, a file system which allows applications to create, inspect, modify, and remove the mappings established between individual files and physical storage. MapFS gives users increased power and flexibility, facilitates true end-to-end application design, and optimizes many common file system tasks. 1

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
