slices, and `PTD-23.1` is a nested container rather than a delivery slice.
Their explicitly enumerated leaf slices are first-class delivery items: each
owns one commit and one PR, while a container owns neither.
The sole authorized review-subdivision exception is `PTD-23.1.4`, which remains
one delivery item and introduces no additional `PTD-*` identifiers. Its
contiguous three-PR sequence is PR 149 for shared binding-contract hardening,
PR 148 for production binding projection, and PR 150 for acceptance
hardening. `PTD-23.1.4` completes, and `PTD-23.1.5` may activate, only when all
three PRs retain current-head approval in that order.
`PTD-21` completes only when `PTD-21.1` through `PTD-21.5` have current-head
approval; `PTD-22` completes only when `PTD-22.1` through `PTD-22.3` do; and
`PTD-23.1` completes only when `PTD-23.1.1` through `PTD-23.1.8` do. `PTD-23`
