Validation API and profile model

Status: Complete for the agreed v0.2.0 shared validation model. Every selection and execution path described here is implemented and locally verified; broader consumer adoption remains in the product roadmap.

This roadmap describes the shared model that enables the optional validation capabilities in the v0.2.0 roadmap. It owns their common API, configuration, execution, and diagnostic design. The release roadmap owns each capability's purpose and scope. The implementation plan owns the stages and the agreed API rollout.

Rationale and v0.1.0 baseline

ReleaseKit v0.1.0 exposes Check and Publish through the root facade. Both accept ReleaseRequest and use shared candidate-validation machinery. Validation runs the standard offline Go suite, followed by AdditionalChecks when supplied. Selected executable builds follow validation. The CLI maps profile checks commands to the additional-check callback.

This provides a common procedure and a product-specific extension point. The request and profile have structured selections for race testing, separate full vet, package compilation, formatting, Markdown, module distribution, and file size. Publication also supports an expected push endpoint.

The model lets consumers declare their choices once while ReleaseKit owns execution and coordination. This follows ADR 0002: shared capabilities should reduce application code and routine developer decisions. The facade boundaries in ADR 0001 provide the existing architectural foundation.

Optional capabilities can serve a small subset of consumers when they remove application-owned release mechanics and have clear scope, compact configuration, and proportionate maintenance costs.

Target end state

One validation specification

The facade-owned ValidationSpec on ReleaseRequest has a corresponding validation object in the release profile. Typed Go fields and ordinary JSON settings express the same supported selections. Related choices, including base-test and vet settings, are grouped so their relationship is clear.

The specification includes the agreed capabilities in the release roadmap, including optional Markdown boundary enforcement, independent module-distribution rules, and file-size settings. Its zero value and an omitted profile object preserve current default validation. Consumers enable optional checks according to their product needs.

Go callers and CLI users receive equivalent validation behavior. The CLI owns profile parsing and presentation; the facade owns the public types and contracts; internal implementation owns execution. The implementation plan records the selected field names, representations, and completed rollout.

Shared coordination

Check and Publish pass the same specification through one internal validation path bound to the captured candidate. ReleaseKit constructs the selected Go commands, manages its shared environment, determines execution order, and propagates failures and cancellation.

Race selection changes the one base suite invocation. Selecting a separate full-vet pass automatically omits test-time vet. Package-compilation targets express compatibility checks independently of executable artifact selection. Consumers obtain this coordination through their declarations.

Keep the executor straightforward and internal, with ordinary functions for the selected capabilities. The public model expresses validation choices; ReleaseKit maintains their execution procedure. Existing candidate rechecks, offline validation, and source-publication outcomes retain their meaning.

Candidate-content inspection

File-oriented checks share candidate-file enumeration and inspection where useful. Their scope is the captured candidate, and inspection remains offline and read-only. Inspect committed candidate contents and define symlink and submodule handling explicitly in the shared inspection model. Module-distribution rules inspect the files being released independently of the environment used to run Go commands. Markdown boundary validation operates independently of neighboring checkout contents.

Keep each check's settings together: Markdown validation owns its optional boundary rule; module-distribution validation owns its independent rule selections; file-size validation owns its limit and path exclusions. The release roadmap defines the scope and defaults of each capability.

Clear responsibility boundaries

Concern Model owner
Base tests, full vet, and package compilation Shared validation specification
Formatting, Markdown links, module distribution, and file size Shared validation specification
Product-specific assertions and example checks Existing AdditionalChecks callback and profile checks
Expected authoritative push destination Publication settings and endpoint handling
Executable package, binary name, and artifact targets Build declaration
Hosted destination and credentials Delivery settings

AdditionalChecks and profile checks remain available for substantive consumer behavior. Shared capabilities use the validation specification. Preserve the current behavior of existing declarations as the new options land.

The expected-endpoint feature remains a publication guard, and Check remains local-only. Selecting package-compilation checks leaves a source-only consumer's deliverable selection unchanged. Tool installation and dependency preparation remain separate from offline candidate validation.

Consistent diagnostics

Shared validation failures identify the check and expose useful details to Go callers. File-oriented checks provide source locations and actionable findings where applicable, including relevant paths, directives, and measured values. The CLI presents those details consistently through the ordinary candidate-check and publication commands.

Use a small facade-owned error model with stable check identity and support for underlying error causes and cancellation. Preserve errors.Is and errors.As behavior across internal conversions and facade wrapping. Exact error types and diagnostic fields are proposed in the implementation plan.

Validation failures and publication outcomes have distinct meanings. Existing publication states continue to describe whether publication was attempted, confirmed, conflicted, or remains uncertain. The model preserves the existing failure-stopping behavior of the candidate workflow.

Implementation

The implementation plan records the completed rollout and verification. The facade and CLI profile expose equivalent selections for the single test suite, separate full vet, package compilation, formatting, Markdown, module distribution, file size, and the expected publication endpoint. Shared execution, ordering, diagnostics, cancellation, and failure stopping are implemented by the owners described above. The maintained Woodpecker template and Audita's local wrapper use the module-selected ReleaseKit version; see the v0.2.0 roadmap and delivery guide.

Adoption evidence

Self-contained integration fixtures evaluate all three known consumer shapes: Audita's default validation and executable builds; ConfigKit's selected test, vet, and library compilation checks; and PromptKit's shared validation plus substantive example assertions. Audita's module-selected CI migration is committed at 17421bc; the other consumer migrations remain separate adoption work.

The model gives each adopting consumer a small declaration and the same routine release operation. Shared execution and diagnostics cover the agreed v0.2.0 capabilities while product-specific work remains in the existing extension point.
