IP-321 Delivery Handoff

• Phase: Delivery
• Status: code, docs, and blocker repairs ready; T11 commit/push and post-push stack gate pending
• Scope: IP-321 with IP-337, IP-338, and IP-339
• Artifacts: SPEC.md, PLAN.md, IMPLEMENTATION-NOTES.md, Command Discovery, and CLI Presentation Contract.
• Delivery vehicle: draft PR #87 from team/stefan/m7-m9-effect-v4-convergence to team/stefan/refactor-cli-architecture; no stack, merge, commit, deployment, or PR-update claim.
• Product acceptance: IP-337 one-result/root-boundary contract, IP-338 recursive discovery graph, and IP-339 renderer/catalog contract are implemented.
• Validation: focused final blocker 119/119; Effect 93/93 with 1,353 expectations; standard types passed; build 535; distribution assertions passed; catalog 5/5 with 66 frames and 6 screenshots; dry package 663 files with hi and hint and zero catalog files; check:repo passed; wiki 2/6.
• Full CLI state: one post-isolation run recorded 690 passed, 1 failed, and 2 errors across 4,216 tests and 66 files. The isolated pre-existing harness conditions were hooks cached PATH at 5/1 and an @effect/vitest it.for load error; neither is classified as an IP-321 product failure.
• Aggregate state: behavior contract 4/4 and backoffice browser 8/8 passed. Cleanup then failed with EPERM at process.kill(-pid); runner repair belongs to IP-324.
• Wiki build state: direct Fumadocs and Next type generation succeeded; standard TypeScript passed; native TypeScript 7 reports .source/server.ts is not a module; direct build reaches seven older title-frontmatter failures.
• UI evidence: six current screenshots and exact hashes are recorded in IMPLEMENTATION-NOTES.md. No before screenshot exists because the catalog is a new review surface.
• Runtime cleanup: browser sessions closed, run-owned temp removed, port 4056/route absent, shared portless proxy retained.
• Review state: autoreview was clean before final independent blockers were found; those blockers were repaired. No final independent PASS is claimed yet.
• Next route: final independent acceptance, commit, push, draft PR update, then the parent-owned post-push stack gate. No stack status or synchronization evidence is claimed before that gate runs.
