[v1 readiness][kratos] npm/native addon artifact smoke gate

Goal

Prove the actual npm artifacts and native addon optional dependency path work, not just the source checkout tests.

Source of Truth

• Parent epic: [v1 readiness] Kratos release gate epic (no version bump) #90
• Repo: JeremyDev87/kratos
• Parent implementation plan artifact: /Users/pjw/.hermes/thread-workcells/discord/282499436049858561/1508085811139051580/TASKS/v1-ddplan-issues/IMPLEMENTATION_PLAN.md
• Version bump, tag, publish, CI dispatch, branch, commit, and PR creation are out of scope for this issue.

Wiki Context Manifest

• Queries attempted: frontend evidence gates release evidence contract, code is not cheap AI maintenance cost ratio, alex core invariants SSoT No Silent Fallback idempotency, 12-factor agents runtime contract event log release workflow, overeager coding agents task scope destructive action, prompt assets skill issue planning evidence
• Wiki sources read: [wiki: frontend/evidence-gates.md], [wiki: principles/code-is-not-cheap.md], [wiki: principles/alex-core-invariants.md], [wiki: harness-engineering/12-factor-agents-runtime-contract.md], [wiki: harness-engineering/overeager-coding-agents-scope-contract.md], [wiki: harness-engineering/prompt-assets.md], [wiki: raw/2026-05-24-ai-maintenance-cost-ratio-source-map.md]
• Relevant wiki facts: v1 readiness requires artifact/runtime/evidence bundles, not only test-green; release and wrapper flows must preserve SSoT, atomicity, idempotency, and No Silent Fallback; destructive or fix-like commands need task-scope/evidence gates; AI-generated velocity must lower future maintenance cost rather than add broad v1 scope.
• remember-wiki applicability / skip reason: skipped; target repos are JeremyDev87/* personal CLI repos, not Remember/dramancompany repos.
• Non-wiki inference: repo-specific split below is based on live local repo docs/config/workflows and npm registry checks performed before issue creation.

Quality Lens Router Output

• Applicable gate families:
  • evidence-contract: v1 readiness, package install, CLI output, release/publish, and fallback claims need concrete proof.
  • simplicity-deletability: v1 work must prefer contract/evidence gaps over broad new features or nonessential abstractions.
  • tdd-systematic-debugging: false-positive, fallback, exit-code, and packaging regressions should be fixture/test-backed.
• Skipped gates:
  • frontend-design: not-applicable; CLI/runtime/docs work only.
  • vercel-agent-skills: not-applicable; no React/Next/Vercel/mobile surface.
  • deploy-token-safety: limited; no token/deploy mutation in this issue, only release credential evidence requirements.

Evidence Contract

• Required evidence:
  • Candidate SHA/version alignment evidence when a candidate is selected.
  • Repo test evidence plus source CLI smoke.
  • npm pack / packed-install evidence for the user-consumed artifact.
  • Release workflow/check/dist-tag/GitHub Release evidence where release automation is touched.
  • Explicit fallback/unsupported-platform evidence where wrapper/native-runtime selection is touched.
• Evidence not applicable:
  • Browser screenshot/DOM: not-applicable, CLI repos.
  • Production URL: not-applicable, npm/GitHub release surface only.
• Blocking evidence gaps:
  • Final v1 version bump/tag is intentionally out of scope for this issue set.

Owned files / likely touched areas

• package.json
• bin/**
• test/package-smoke.test.js
• test/npm-launcher.test.js
• .github/workflows/ci.yml
• scripts/** if packaging helpers exist

Inspect-only files

• Cargo.toml
• crates/kratos-node/**
• README*.md

Must not touch

• publish to npm
• push git tags
• change package version as part of this issue

Implementation steps

1. Inventory root package files and platform addon package layout.
2. Add/verify npm pack dry-run and packed install smoke that exercises the current platform addon.
3. Ensure missing/unsupported addon failure is explicit and not a silent success.
4. Capture exact artifact evidence expected in PR body.

Parallelization note

Independent from K2 if it stays in packaging/test files.

Dependencies / blocked by

Can run after or alongside K1; avoid changing schema contract.

Validation / evidence required

• npm test
• npm run pack:check
• npm run smoke
• native addon packed install smoke where workflow supports it

Completion criteria

• Required validation evidence is pasted into the PR body or final issue comment.
• No v1 version bump/tag/publish is performed.
• If any required evidence is unavailable, the issue remains open with the gap classified as Medium/High rather than being marked complete.
