A ledger that checks itself

The entity taxonomy is load-bearing: collapse SAGEN's six entity types into one and the engine can no longer represent a topic change at all.

The released engine's four-turn goal evolution is 3 / 4 / 5 / 6 — not the 3 / 5 / 6 / 7 printed in the paper's Table 5. The runnable artifact is authoritative.

Checkpoint after two turns, restore into a fresh engine, run two more: the injection is byte-for-byte identical to running all four continuously.

SAGEN captures 98.5% of the evaluated information dimensions, versus 20.5% for a rolling summary and 10.5% for a raw buffer.

Sparse scoring (2dK) is cheaper than the dense head (2d|V|) for every valid-token count K below the vocabulary size; the two cross exactly at K = |V|.

When the decode margin is large, amortized scoring skips the recompute and accrues cost roughly an order of magnitude slower than full recomputation.

A LinUCB contextual-bandit router learns to route within a few percent of the hindsight oracle, beating both the static-dense and static-sparse policies.

A ~40,000-word interdisciplinary essay built as infrastructure you walk through: six interactive games and thirteen narrated audio sections, not a wall of text.

The DSM hardened into infrastructure at DSM-III (1980), when operationalized criteria displaced the psychodynamic paradigm in response to the reliability crisis.

The planning-execution gap is structural, not a discipline failure: planning is an inside-view, System-1 narrative act, so the plan reliably beats the base rate in how good it feels.

A 38,000-word synthesis across ten disciplines, from neuroscience to information theory, with every load-bearing claim carried to a linked bibliography.

AI detectors flagged 61.3% of TOEFL essays by non-native English writers as AI-generated, versus 3.2% of essays by US-born writers.

A ~4% per-sentence false-positive rate compounds: a 20-sentence paper has better-than-even odds of containing at least one falsely flagged sentence.

A one-point difference at a diagnostic cutoff (a 71 against a threshold of 70) flips a child from eligible to ineligible, and the classification follows them through the record.

The audit covers 25 U.S. universities across an 11-dimension framework, roughly 1.33 million students in scope, and every dimension score is backed by a quoted policy excerpt with a source link.

The federal state can be read as a portfolio of 49 unexercised options, most of them illegible to any evaluator that scores only observable output.

Ukraine's State Register of Property Rights is about 40% complete and mostly post-2013, so a pre-2013 paper-deed owner cannot prove ownership — the gate assisted filing cannot open.
