abstract
We refine and extend a recent construction of sets of black hole microstates with semiclassical interiors that span a Hilbert space of dimension $e^S$, where $S$ is the black hole entropy. We elaborate on the definition and properties of microstates in statistical and black hole mechanics. The gravitational description of microstates employs matter shells in the interior of the black hole, and we argue that in the limit where the shells are very heavy, the construction acquires universal validity. To this end, we show it for very wide classes of black holes: we first extend the construction to rotating and charged black holes, including extremal and near-extremal solutions, with or without supersymmetry, and we sketch how the construction of microstates can be embedded in String Theory. We then describe how the approach can include general quantum corrections, near or far from extremality. For supersymmetric black holes, the microstates we construct differ from other recent constructions in that the interior excitations are not confined within the near-extremal throat.

A Nonperturbative Toolkit for Quantum Gravity
A shell-state resolution of the identity, an infinite-overcompleteness limit, and geometric surgery are claimed to prove fine-grained factorization of the two-sided gravitational thermal partition function.

Flow-geometry microstates
Particle-insertion microstates in AdS2→dS2 flow geometries are counted via wormhole path integrals, giving a Hilbert-space dimension e^{2S_Flow} that matches Gibbons-Hawking; the purely-de Sitter spanning claim depend...

Observing Spacetime
An asymptotic observer can check a proposed quantum gravity microstate with a probe tuned to the state's creating operator, because extra wormhole saddles make the response O(1) larger than any generic probe.

How to Count States in Gravity
The Gibbons-Hawking Euclidean gravity path integral with periodic time equals an explicit thermal trace over the single-boundary quantum gravity Hilbert space.

Non-conformal Line Defect (Shell Operator) in AdS$_3$/CFT$_2$: Spinning and Higher Point Correlators
Spinning and higher-point thin-shell operator correlators in AdS3/CFT2 are shown to match across ETH analysis, the vacuum Virasoro block, and gravitational on-shell actions, with order-dependent structure for multiple...

It from ETH: Multi-interval Entanglement and Replica Wormholes from Large-$c$ BCFT Ensemble
The RT formula for entanglement in AdS3/CFT2, including phase transitions and multi-interval vacuum entropies, is derived from an assumed large-c ensemble of (B)CFT data, under the 'It from ETH' paradigm.

Spread complexity and the saturation of wormhole size
For finite-N DSSYK, the chord basis is the early part of the physical Krylov basis, and spread complexity, taken as the non-perturbative ER bridge size, saturates after a universality-class-dependent peak and slope.

The Baby Universe is Fine and the CFT Knows It: On Holography for Closed Universes
A closed universe in AdS/CFT is not ruled out by recent SWAP-test arguments; the one-dimensional Hilbert space seen from the CFT is external indistinguishability, and CFT data can reconstruct the closed universe's geometry.

A Note on Black Hole Entropy and Wormhole Instabilities
A microcanonical treatment of Euclidean wormhole overlap integrals removes Jeans and GPY instabilities and yields the expected black hole entropy without spurious phases.

Non-Locality induces Isometry and Factorisation in Holography
State-averaged wormhole corrections make the Gram matrix of time-shifted thermofield double microstates low-rank, giving a finite black hole Hilbert space of dimension e^{S_BH} and a type I von Neumann algebra.
