feat: add RunContract evidence criteria

[devkade]

Summary

• Adds generic EvidenceExpectation and CompletionCriteria primitives to the RunContract domain view.
• Derives inspectable missing/satisfied criteria from existing ValidationEvidence and required artifacts.
• Keeps this additive and generic: no policy module, no adapter-specific rules, and no replacement of existing workflow validation.

Issue

Closes #99

Implementation notes

• RunContractView now includes expectations, completionCriteria, and completion.results.
• Default expectations include evidence:any and required artifact expectations derived from existing workflow artifacts.
• evaluateCompletionCriteria() reports satisfiedExpectationIds, missingExpectationIds, and clear missing-evidence reasons.
• Existing completion summary now surfaces needs-evidence when required generic expectations are missing.

Verification

• npm test -- test/run-contract.test.ts
• npm run verify
• git diff --check
• grep -RniE 'github|pullRequest|issueNumber|kapiAgent|discord|ragna' src/domain/run-contract.ts test/run-contract.test.ts returned no matches

Notes

• npm run verify still reports the existing non-failing quality budget warning: code_smells=44, target <=20, status warn.

Final approval summary

Review journey

• Reviewed feat: add RunContract evidence criteria #110 at head 72b10d1a35c71229612103c730f3dc974c49dd7b against feat: model EvidenceExpectation and CompletionCriteria for RunContract #99.
• Checked that RunContract criteria remain generic and derived from existing WorkflowState / WorkflowDefinition data.
• Confirmed no GitHub, PR, Discord, Ragna, or kapi-agent adapter concerns entered the domain file or tests.

Evidence

• git diff --check passed before commit.
• npm test -- test/run-contract.test.ts passed.
• npm run verify passed.
• Domain boundary grep returned no adapter/branding matches for src/domain/run-contract.ts and test/run-contract.test.ts.

Notes

• npm run verify still reports existing non-failing quality budget warning: code_smells=44, target <=20, status warn.
• This is acceptable for this slice; it is an advisory quality budget warning, not a failing gate.

Decision

Approved for merge into dev.

Verdict: REQUEST_CHANGES

Blocking issues

• src/domain/run-contract.ts: required artifact expectations are labeled as “Required artifact is tracked”, but the evaluator only satisfies them when some ValidationEvidence record references that artifact via evidence.artifactRefs.
  • This makes the RunContract contract internally inconsistent: state.artifacts can clearly contain the required artifact, while completion.results[].missingExpectationIds still reports artifact:<name> as missing with the reason “Required artifact is tracked: ”.
  • Either change the satisfaction logic so artifact expectations are satisfied by the required artifact being present in state.artifacts, or change the expectation summary/criteria semantics to explicitly require validation evidence for each required artifact.
  • Please add a direct test for the intended behavior with required artifacts present and evidence present but not referencing the artifact.

Warnings / risks

• test/run-contract.test.ts: the “complete” test only reaches completion by replacing artifacts: [], so it does not verify the normal case where workflows have required artifacts. This leaves the main new criteria path under-tested.
• src/domain/run-contract.ts: artifactRefs currently means two things: expected artifact existence and evidence-reference matching. That ambiguity is likely to confuse future contract consumers.

Suggestions

• Consider renaming the field or splitting the model if both concepts are needed:
  • requiredArtifactRefs / requiredTrackedArtifacts
  • evidenceArtifactRefs
• Consider making missing reasons more explicit, e.g. “No validation evidence references required artifact: verify.md” if evidence linkage is the intended rule.

Looks good

• The new RunContract fields are additive and stay within the domain layer.
• Existing evidence projection still avoids aliasing mutable arrays.
• The completion status now exposes a useful needs-evidence state instead of treating completion as purely lifecycle-derived.

Verification notes

• Verifier gate status: PASS — npm ci && npm run verify exited 0.
• Size gate status: PASS — 95 changed lines, under the 200-line limit.
• Revision-explanation status: not required for this opened PR; found in PR body.
• I inspected src/domain/run-contract.ts and test/run-contract.test.ts. The blocking issue is semantic/contract correctness, not CI failure.
