SPEC §3.1 defines the pin a manifest carries (conditioning.prior, and a WAI2 rendition's prior): id, sha256, determinism, and the optional form, tier and supersedes. The digest covers the whole parameter set. A set of several files is pinned through its listing, the new registered prior form wai.prior.set. A sink verifies the pin before it decodes, reports a refusal with one of an ordered set of snake_case reasons, and decodes only from the set it verified. Tier is a closed vocabulary; supersedes is informative. A pin that does not resolve makes its capability unsupported for that envelope: SPEC §4 dispatch continues at the fallback, §7.1 selection at the next rendition, and an inert envelope's error names the reasons. A rendition entry may carry id, sha256 and, on a companion, companion_of_id. SPEC §7 gains a Digests subsection, and §8 says how a MINOR revision adds an optional member. In wai-rs: the manifest types are #[non_exhaustive] with builders; a new pin module verifies pins in memory and on disk; Wai::dispatch_verified, WaiMulti::pick and primary check pins and component digests; every neural decoder reads through ParamSource; a codec-free `ffi` feature carries the C envelope surface with wai_envelope_select and wai_neural_decode_ex. wai-web wraps wai::container. New vectors: the int_mlicpp set-form twin and the pin-conformance corpus with an independent Python verifier, plus sha256.json sidecars for the vectors of capabilities that decode against a parameter set. Squashed from wai/stream-a-parameter-set-identity onto link 12. Conflicts are resolved to keep both sides; the integration commits that follow make the two streams agree.
