Transaction Science 95849040e3 wai-quantum circuit2: the specification, registry and documentation for both capabilities 
The quantum-sim extension now specifies both capabilities to the bit. Its header
and section 1 name wai.quantum.circuit2 for new content and wai.quantum.circuit
as frozen. Section 2 states the little-endian layout, overflow-free section
bounds, the refusal of a repeated known section, and the three refusal classes
in the order a reader checks them. Section 2.1 gives both canonical contracts,
the ext convention, the circuit/1 reader rules and circuit2's byte-canonical
rule, and defines wai.det.amp64 and the meaning of wai.det.fixed64 inside a
circuit/1 contract. Sections 2.2 and 2.3 state the op-log and measurement rules
per capability. Section 3.0 states the shared arithmetic, the index convention
and the gate matrices. Section 3.1 gives the exact circuit/1 recurrence and the
deviation of every entry and no longer claims that table gives the QFT. Section
3.2 defines the circuit2 table as the nearest integers, makes the literal table
normative with its digest, and gives the interval-certified derivation as
informative. Sections 4 to 6 state the hash and sampler layouts, the error per
capability and how receipts name their capability, and a new section 8 says
why circuit2 is a capability of its own, what older readers do, and which
circuit/1 payloads become non-conforming.

Appendix B holds both phase tables and digests, rendered from PHASE_V1 and
PHASE_V2 by a new wai_quantum_vectors appendix subcommand. A bin test fails when
the text differs from the constants, and the referee requires Appendix B to
state its literal tables; wai-conformance now triggers on the extension.

SPEC.md names wai.det.amp64 and lists the newly non-conforming circuit/1
payloads. The registry adds wai.det.amp64 as an identifier and annotates
wai.det.fixed64, and the export is regenerated. The crate rustdoc, the crate,
wai and quantum-conformance READMEs, and the changelog describe both
capabilities, the corpus coverage and its limits, and the 0.4.0 migration.

# WAI registry
The registry is the set of strings [SPEC §5](SPEC.md) registers, with the classes
the specification gives each one. Its source of truth is one table in the
reference implementation, [`wai-rs/src/codecs/registry.rs`](wai-rs/src/codecs/registry.rs)
together with the class functions of [`wai-rs/src/codecs/mod.rs`](wai-rs/src/codecs/mod.rs).
`wai registry export` writes it out in machine-readable form:
| file | what |
|---|---|
| [`registry/capabilities.json`](registry/capabilities.json) | every registered string with its kind, status, media class, role, fidelity tier, licence class, replicate class, set membership, registering section, edition and registration date; the named identifiers that are not capabilities; the unregistered labels; the wire identifiers |
| [`registry/capabilities.schema.json`](registry/capabilities.schema.json) | JSON Schema (2020-12) for that file; its enums are the label sets below |
| [`vocab/v2.ttl`](vocab/v2.ttl), [`vocab/v2.jsonld`](vocab/v2.jsonld), [`vocab/v2.shapes.ttl`](vocab/v2.shapes.ttl) | the same registry as RDF, a JSON-LD context for manifests, and a SHACL shape that checks a manifest's capability and fallback against it, only the form of its media, and its parameter-set pins (`vocab/README.md`); a violation for a string the registry does not hold means the string is not registered in this revision, not that the envelope fails to conform or cannot be dispatched (SPEC §4, §8) |
| the table at the end of this file | the same registry, for reading |
A library test (`codecs::registry::tests::registry_export_matches_committed`) and
a CI step (`wai registry export --check` in `.github/workflows/wai-conformance.yml`)
fail when a committed file differs from what the table renders. Edit the table,
never the exported files.
## Kinds
Every registered string has one kind.
- **payload** — a capability whose payload a sink decodes: it may be a `WAI1`
`capability` or `fallback`, or a `WAI2` rendition.
- **companion** — a companion-only capability (SPEC §5, §7.1): its payload is
applied with a base rendition and never on its own, so it is only ever a `WAI2`
companion.
- **refinement** — a refinement-only capability (SPEC §5, *Refinement
capabilities*): its payload is applied to the output of the stage below it,
bound to that output's producer by content hash, and never decoded on its own.
It is a `WAI1` `capability` with `refines`, or a `WAI2` component with
`role: "refinement"` ([staged-delivery](extensions/staged-delivery.md)). The
bases each one applies over are SPEC §5's *Base admission* table, which also
holds the bases of the enhancement layer `wai.video.lcevc`.
- **derivation** — an operation of ISO/IEC 23001-16 (`wai.derive.*`,
[derived-tracks](extensions/derived-tracks.md)). It acts on samples another
capability decoded and names no payload format.
- **record** — a signed record a WAI tool emits and verifies (a receipt kind:
`wai.asset.provenance`, the quantum-operations receipts, the delivery records
`wai.video.manifest` and its siblings). It names no payload format.
A derivation or record string is not a payload capability, so it is not
dispatchable (SPEC §4): dispatch never takes an envelope's capability that names
one, and step 5 may still take a usable fallback. A refinement is not dispatchable
either; staged-delivery §4 processes it.
Two further tables hold strings that look like capabilities and are not:
- **identifiers** name a part of a capability's definition (`wai.det.fixed64`, the
fixed-point floor; `wai.det.amp64`, the complex amplitude arithmetic of
`wai.quantum.circuit2`; `wai.world.sim.*`, the simulation steps of the feed and
avatar capabilities);
- **unregistered labels** are strings the reference implementation uses as labels
that no revision registers, each with the reason.
A third holds the **wire identifiers**: the names the container, its delivery
bindings ([http-delivery](extensions/http-delivery.md),
[moq-streaming-format](extensions/moq-streaming-format.md)), the key discovery
they serve ([jwp-receipts](extensions/jwp-receipts.md) §7) and
[packaging](extensions/packaging.md) put on the wire outside a
manifest — magic numbers, a media type, `codecs` prefixes, paths, playlist tags and
attributes, document kinds and catalog fields — each with its kind, the section that
defines it, and whether it is defined, provisional (test material only until
registered) or proposed (not registered). A library test checks that each is written
in the section it names.
## Status
- **registered** — the payload format (for a record or derivation, the
definition) is pinned. The WAI-native integer codecs `wai.video.int_motion`,
`wai.video.int_hyper`, `wai.neural.int_hyper`, `wai.audio.int_codec` and
`wai.splat.int_codec` were registered with a decoder and no byte layout (the first,
the fourth and the fifth also with the tool that wrote their bitstreams); v0.4.0
completes their registrations by pinning their formats (SPEC §8, *Completing a
registration*; SPEC §5, *Payloads of the WAI-native integer codecs*).
- **candidate** — the string is registered but no revision has pinned its payload
format. An encoder MUST NOT emit a candidate, and a sink MUST treat it as
unsupported (SPEC §5, *Candidate capabilities*). The reference implementation
lists candidates in `codecs::is_candidate`, reports an envelope that names one
from `Wai::check_candidates` and `WaiMulti::check_candidates`, and never
dispatches or selects one.
Every dispatch and selection function uses one predicate,
`codecs::is_dispatchable(cap)`, SPEC §4's *dispatchable*: false for a
companion-only capability, a refinement-only capability, a candidate, a record and
a derivation; true for a
registered payload capability that is not a candidate, and for a string this
revision does not register, which a later MINOR revision may register (SPEC §8)
and which a sink decodes only if it advertises it. A new dispatch or selection
function MUST use it too.
## Editions
A registration that names an edition of its standard carries that edition. A
registration that names none carries the edition of its named standard current on
the date it was registered, and no later edition or amendment: a later edition or
amendment that changes the bitstream gets a capability string of its own
(SPEC §8, *Editions*). The export records both: `edition` (a designation, or
`null` for the edition current on the registration date) and `registered` (the
date of the first commit of this repository that registers the string; the
specification entered the repository on 2026-06-12, so a string registered before
then carries that date).
## Licence classes
Every payload, companion and refinement capability carries a licence class:
`royalty-free`, `patent-pool`, `proprietary` or `non-commercial`
(`codecs::capability_license`). It is a property of the capability, not a
per-file claim. The classification has no default: a capability registered
without a class is a registry defect the tests reject. The sources and residual
caveats for each class are in
[`research/media-codec-registry.md`](research/media-codec-registry.md). A
capability whose royalty status is not established is classified conservatively
(`patent-pool`), never `royalty-free`; a candidate's class is provisional until a
revision pins its payload format, since the licensing of a format not yet chosen
cannot be established. Every
derivation operation carries the class `codecs::derivation::derivation_license`
gives it; a record carries none.
## How to register a string
1. Add the capability constant to `wai-rs/src/codecs/mod.rs` and, for a payload,
companion or refinement capability, list it in `known_capabilities()` and give it an arm in
`capability_tier`, `capability_license` and `capability_replicate_class` (each
function has no default, and the tests reject a registered capability without
one). A record goes in `RECORDS`, a derivation in `codecs::derivation`.
2. Give it a row in `ROWS` of `wai-rs/src/codecs/registry.rs`: the SPEC §5 heading
it is registered under, the edition it carries, and the registration date. A
string whose payload format is not yet pinned also goes in `CANDIDATES`.
3. Register it in SPEC §5, under that heading, with its payload format and role.
The test `spec_and_registry_name_the_same_strings` holds SPEC and the table to
the same set of strings, in both directions.
4. Run `cargo run --no-default-features --bin wai -- registry export` from
`wai/wai-rs`, and commit the files it writes.
5. Link it from the codec glossary entry that describes its bitstream, or list it
in the glossary's `GLOSSARY_NO_ENTRY` table with the reason
([`glossary/SCHEMA.md`](glossary/SCHEMA.md)).
6. Add a CHANGELOG entry.
Changing what a registered string carries is governed by SPEC §8: a payload format
and a role are fixed once registered.
