Independent computation

Look closer. Things are already moving.

Independent computer science and computational experimentation, published with evidence clear enough to inspect and limits clear enough to trust.

The work

Named here. Linked when the signal is public.

Some work is still private. It belongs in the index anyway.

    Clock Dataset

    What was actually knowable at the moment of a decision?

  2. 02
    StudyPublic

    Decision Assurance

    When does a score stop being enough for a finite-capacity decision?

  3. 03
    StudyPublic

    Degradation Diagnosis

    How much can a model’s trouble be diagnosed before its labels arrive?

  4. 04
    StudyPublic

    Release Equivalence

    Is the system after release still the one you tested?

  5. 05
    StudyPrivate

    Delayed Feedback

    Evaluating policies when outcomes arrive late, selectively, and after the policy has changed.

  6. 06
    StudyPublic

    DeepLOB

    How an experiment can manufacture confidence from a market with no signal.

  7. 07
    StudyPublic

    Spectral Recovery

    A controlled look at when correlation-matrix denoising helps—and when it does not.

  8. 08
    StudyPublic

    Tail Estimator Audit

    Known-tail experiments for finding where familiar estimators bend or break.

  9. 09
    FindingPublicFlagged

    Evidence that exists and cannot be retrieved

    A successful empty audit query did not establish an empty record — 192 records sat in the log the whole time.

  10. 10
    Experimental corePrivate

    Systems & Security Core

    Range harnesses, evidence ledgers, and provenance tools for difficult systems questions.

    StudyPrivate

    Security Decision Invariance

    When a transformed event record still supports the same security conclusion.

    ShelfOpen shelf

    Agentic Systems

    A deliberate open shelf for work on autonomous software, tools, and accountable coordination.

    EnginePrivate

    GPU Simulation Engine

    GPU-first compute and rendering for typed simulation state.

    Cascade Field Study

    A deterministic field for watching a local shock remain bounded—or become a cascade.

Ways in

Four frequencies. No departments.

Different ways of following a system until it starts saying something interesting.

S&S3 named

Systems & Security

Traces, hidden state, recoveries, and the gap between what a system says and what it did.

Tune in
AGT1 named

Agentic Systems

Autonomous software, tool use, coordination, and agents with some explaining to do.

Tune in
CMP2 named

Computation

Simulation, visual systems, unusual machinery, and complexity made visible.
