Transaction Science 1601d35496 wai: an encrypted envelope's clear parts checked; a record or derivation is no component
§2.4.12, against the envelopes:
- An encrypted envelope (SPEC §6.4) is held: its manifest and rendition table
  are in the clear, so rules 4-9 read them as any held envelope's — the
  rendition an entry names, its capability, the component rules, a base's
  layer count, a companion-only capability, a fallback, a layer's refines and
  span — and leave to the signer only what needs a payload: its digests, a
  base's units and a layer's WIR1 payload. Rule 9 reads the classical length
  every well-formed WAI2's table declares, encrypted or not.
  Vectors: the review's three probes (rendition 9 of two, a relabelled
  rendition, the WAI2 named with no rendition), a base at two layers, a
  companion-only capability, a nonconforming refinement, an encrypted layer
  over an encrypted base (accepted). Re-derived, outside the pinned prefix:
  session_envelope_encrypted (390) now accepts; the classical-null case is
  session_envelope_encrypted_classical_unstated (389); session_envelope_inert_
  unnamed_accept (397) states the classical length the encrypted table adds.
- §2.4.12's signer's statements name whether a refinement's exploded envelope
  held as its own bytes was received on its own.

SPEC §7.1: a component whose capability is a record or a derivation does not
conform, in any role (record-or-derivation-as-component), in check_component_
roles and claim_verify.py; pin-conformance/selection.json gains a record and a
derivation rendition, and its two companion cases take the new finding.
session_roles_record_rendition pins it in the claim corpus. 555 vectors.

staged-measurement's countability is cited by its heading (§3), so the
section-refs check passes. differential.py adds an encrypted-envelope family.
