# parityEvidence

A parity evidence record carrying label, timing, trace, summary, note.

Last updated: 2026-09-09

Package: compute.parity | Status: source-declared

Tags: compute, compute.parity, cpu, method, parity, source-example, thing, yeho

Compare numerical results with explicit tolerances and CPU-reference evidence.

```yh
external thing parityEvidence
```

- text label: Stores label as text.
- profileTiming timing: Stores timing as profileTiming.
- profileTrace trace: Stores trace as profileTrace.
- paritySummary summary: Stores summary as paritySummary.
- text note: Stores note as text.
- parityEvidence(text label, profileTiming timing, profileTrace trace, paritySummary summary, text note): Parity evidence.
- Describe() returns text: Describe.

## Use parityEvidence

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using compute.parity

// Compare numerical results with explicit tolerances and CPU-reference evidence.
parityEvidence sample = parityEvidence("Player health", profileTiming("Player health", "stage", "origin", 1, 1, "note"), profileTrace("Player health", shapeTrace("Player health", "origin", tensorShape("element Type", []), "note"), valueTrace("Player health", "origin", [], "note"), "note"), paritySummary(), "note")
Console.Log(Text.From(sample.label))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.compute_parity__parityevidence"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "compute.parity"
version = "0.1.0"
path = "../../../yeho/packages/compute/parity"

[[dependencies]]
package = "compute.profiling"
version = "0.1.0"
path = "../../../yeho/packages/compute/profiling"

[[dependencies]]
package = "compute.simd"
version = "0.1.0"
path = "../../../yeho/packages/compute/simd"

[[dependencies]]
package = "compute.tensor"
version = "0.1.0"
path = "../../../yeho/packages/compute/tensor"

[[dependencies]]
package = "console"
version = "0.1.0"
path = "../../../yeho/packages/console"

[[dependencies]]
package = "diagnostics"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/compute.parity--parityEvidence/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## parityEvidence.Describe

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using compute.parity

// Describe.
parityEvidence instance = parityEvidence("Player health", profileTiming("Player health", "stage", "origin", 1, 1, "note"), profileTrace("Player health", shapeTrace("Player health", "origin", tensorShape("element Type", []), "note"), valueTrace("Player health", "origin", [], "note"), "note"), paritySummary(), "note")
text result = instance.Describe()
Console.Log(Text.From(result))

```

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
