name: WAI energy receipts

# Tests of the energy acquisition class (extensions/energy-measurement.md §2):
# the class rules, the optional labels, the resolution floor, the pins that
# hold legacy receipts (unlabelled, or labelled with the legacy HwShunt) and
# labelled ones to the signed bytes they have; the measurement report's
# arithmetic and the liveness rule (§3.1, §6.2) with their fault-injection
# tests; the figure views a report is checked against, for every receipt
# family the set compiles; and the reference meters' report path. Three
# steps, on linux (x86_64), linux-arm64 and macos (arm64):
#
#   1. wai-rs: `cargo test --locked` with the feature set in the step, over
#      --lib, --bins and --test video_receipt. That runs the library's unit
#      tests under those features (energy_class, energy_report, energy_burst,
#      energy_meter, energy_binding, energy_figure, the label and pin tests of
#      the wai-rs receipt families, the video and OTT receipt tests, and — with
#      receipt_claims — the claim classes and jwp_delivery); the unit tests of
#      every bin target
#      the set can build (one whose required features are all on), which also
#      proves those bins compile; and the one integration test file
#      tests/video_receipt.rs.
#   2. wai-quantum: `cargo test --locked --features full --lib --tests`: the
#      crate's unit tests, among them the pins and label tests of every quantum
#      receipt, and its integration tests — tests/bit_identity.rs, which pins
#      one result of each f64 layer so every architecture here must produce
#      the same bits, and tests/utility_reference.rs, which holds the 127-qubit
#      results to published values. The tests already marked #[ignore] stay
#      ignored.
#   3. wai-quantum-serve: `cargo test --locked --lib`, native: the verdict
#      logic behind POST /verify, for a receipt in either form, and that an
#      unmetered receipt's 0 is rendered as the unmetered marker (null), never
#      as zero joules.
#
# It does NOT:
#   - check that a newly sealed receipt in a family with an optional label
#     (§2.8) is labelled. A verifier cannot: there an unlabelled receipt
#     sealed today has the bytes of a legacy one. A test of each producer's
#     labelling path could, and none is written; those families'
#     constructors take no class, and a label is added afterwards. It checks
#     the label rules for the receipts that carry one, and that four of the
#     five reference meter bins still build with their report path
#     (wai_video_meter, wai_meter, wai_world_meter, wai_quantum_meter).
#   - run a meter against a power reader. The report path is tested in the
#     library (energy_figure::meter_report), and the protocol against
#     scripted readers (energy_burst, energy_meter).
#   - build wai_prov (needs `codecs`, which links system libjxl) or the
#     wai-quantum CLI bin (needs quantum_toolchain, quantum_qir,
#     quantum_channel, quantum_comm and quantum_qudit). Cargo skips a bin whose
#     required features are off without saying so.
#   - run any other integration test in wai/wai-rs/tests (world_model and
#     world_replay among them), or a doc-test of any of the three crates.
#   - compile c2pa_emit, which carries the energy binding into a C2PA
#     manifest; the c2pa-emitter job of wai-conformance.yml tests it. Nor
#     `oer`: an OER receipt grades its figure and carries no acquisition
#     class, and energy-measurement.md §1 leaves it out of scope.
#   - verify the JWP corpus; wai-conformance.yml does that, and joule-code's
#     workflow tests joule-moq against literals copied from it.
#   - build wai-web, or the wasm32-wasip2 component of wai-quantum-serve.
#   - verify the conformance corpora; wai-conformance.yml does that.
#   - run on Windows. The pinned bytes are integers and hashes and make no
#     OS-specific claim; the conformance matrix has no Windows leg either (its
#     runner is offline).
#
# It triggers only on changes under the paths listed below; a change to
# wai-web alone does not trigger it.

      # One feature set that compiles the wai-rs receipts that carry an
      # acquisition class, except the C2PA emitter (see the header): the video

      # meters, the optional-label families and their pins, and the quantum
      # re-exports with the cross-crate encoding test. --bins compiles every

      # The fifth, wai_prov, is NOT built by this or any workflow: it requires
      # the `codecs` feature, which links system libjxl (>= 0.11), and no
      # workflow enables `codecs` or installs libjxl. Cargo skips a bin whose
      # required features are off without saying so. Its metering is
      # energy_burst, whose tests run in the lib suite; the bin itself is
      # checked only by hand.
