 ## Unreleased
 
+- iOS regular `snapshot --depth` now measures depth after structural accessibility wrappers
+  collapse. The recursive-tree backend follows a bounded presented-depth frontier, so controls
+  that fit the requested regular depth are no longer lost behind raw wrappers; raw `--depth`
+  remains a traversal-depth limit. Flat query recovery is limited to one presented level, and
+  private AX does not claim deeper regular-depth completeness until it has a hierarchy-aware
+  frontier (#1797).
 - iOS regular snapshot nodes now publish presentation-owned effective geometry through the existing
   `rect` field: backend-reported frames remain available to acquisition, while regular output uses
   the viewport and declared scroll-clip intersection. Raw snapshots and direct element reads retain

+The visible-depth frontier completes that migration for unscoped regular captures. `CaptureHint`
+keeps raw traversal depth (`--raw --depth`) separate from regular presented depth. A
+hierarchy-capable tree capture walks through structural wrappers until each branch ends or reaches
+the requested presented depth; regular presentation then applies the depth limit after the shared
+fold and eligibility collapse. This keeps shallow probes bounded by the requested presented
+frontier without inventing a raw-depth multiplier. Scoped captures remain broad because depth is
+relative to the scope root selected in presentation.
+
+Backend capability declarations are part of the contract: recursive tree supports the presented
+frontier, the flat query sweep supports only its root and one presented level, and private AX is
+raw-depth-only for regular depth requests until it has an equivalent hierarchy-aware frontier.
+The capture plan does not claim deeper regular-depth completeness from a backend that cannot prove
+it. Raw depth remains acquisition depth for every backend.
+
+Acquisition-side limits remain explicit: raw private-AX captures still disclose their bridge-side
+node cap, the flat query sweep still drops frameless elements because it has no hierarchy to attach
+geometryless semantics to, and the recursive tree still has no raw-depth extension for deep XCTest
+trees. Presentation cannot repair any of those acquisition limits.
