In this chapter of the Protostars and Planets VII, we review the breakthrough progress that has been made in the field of high-resolution, high-contrast optical and near-infrared imaging of planet-forming disks. These advancements include the direct detection of protoplanets embedded in some disks, and derived limits on planetary masses in others. Morphological substructures, including: rings, spirals, arcs, and shadows, are seen in all imaged infrared-bright disks to date, and are ubiquitous across spectral types. These substructures are believed to be the result of disk evolution processes, and in particular disk-planet interactions. Since small dust grains that scatter light are tightly bound to the disk's gas, these observations closely trace disk structures predicted by hydrodynamical models and serve as observational tests of the predictions of planet formation theories. We argue that the results of current and next-generation high-contrast imaging surveys will, when combined with complementary data from ALMA, lead to a much deeper understanding of the co-evolution of disks and planets, and the mechanisms by which planets form.

WIde Separation Planets In Time (WISPIT): A Gap-clearing Planet in a Multi-ringed Disk around the Young Solar-type Star WISPIT 2
Direct imaging of the young star WISPIT 2 reveals a 380-au multi-ringed disk and a co-moving, gap-embedded companion consistent with a 4.9-MJup planet in Keplerian motion.

Angular Momentum of Planet-Forming Disks: Implications for Infall Driven Misalignments
Most planet-forming disks have less angular momentum than late-infalling cloud gas is predicted to carry, so infalling streamers are a plausible cause of the observed misalignments.

Puffed-up Edges of Planet-opened Gaps in Protoplanetary Disks. II. The Role of the Planet's Orbital Eccentricity
Eccentric gap-opening planets enhance dust lofting at gap edges via stronger meridional circulation, make gaps leaky to dust, and produce larger, wider pebble rings than circular planets.

Infall Explains the Disk Kinematics of AB Aur Without Gravitational Instability
Infalling gas streamers, not disk self-gravity, can produce the convergent velocity signature around the AB Aur spiral arms that was used as evidence for gravitational instability.

The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): X. Dust Substructures, Disk Geometries, and Dust-disk Radii
Analysis of 30 protoplanetary disks finds dust substructures in about 80% of resolved young Class I disks and a rising fraction of large inner dust cavities in older regions, suggesting early and efficient planet formation.

Grand Design Spiral Arms in the Compact, Embedded Protoplanetary Disk of Haro 6-13
The compact disk around Haro 6-13 shows two low-contrast millimeter spiral arms and is likely optically thick interior to about 30 au.

The fraction of polar aligned circumbinary disks
The polar-aligned fraction of circumbinary disks is predicted to scale roughly as binary eccentricity for low-mass disks and approach 0.37 for high disk-to-binary angular momentum ratios.

Water gas discs in exo-asteroid belts
Water vapour from exo-asteroid belts around solar-mass and heavier stars can supply ocean-scale water to inner planets and remain detectable for tens of Myr with current facilities.

Exploring the radial velocity variations of RY Lup with VLT/ESPRESSO: Binary versus spot hypotheses
RY Lup's 3.75-day RV and LSD variations are compatible with a ~0.04 au binary (q~0.6, e~0.23, i~13°) or with multi-spot activity, but both interpretations have serious physical tensions.

Dust Growth in Binary Systems: Inhibition of dust settling and growth in circumbinary discs
Dust grains in circumbinary discs end up five times smaller than in single-star discs, and the conditions for streaming-instability clumping are not met, arguing against in-situ planet formation there.

Radiative Transfer Modeling of a Shadowed Protoplanetary Disk assisted by a Neural Network
The shadow over the southern half of the V1098 Sco protoplanetary disk is best explained by a misaligned inner disk, with rotation axes of the inner and outer disks separated by 38 degrees.

exoALMA. XVIII. Interpreting large scale kinematic structures as moderate warping
Moderate disk warps of about 0.5 to 2 degrees can reproduce the single-armed velocity patterns seen in many exoALMA disks, and may also explain spiral structures in scattered light and CO temperature.
