Schema Approval Surface Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Replace the raw { "type": "object" } interrupt proof in the defense demo with a reusable schema-aware approval surface that can be used by Scene 10, prepared-agent approval messages, and future console interrupt/resume flows.

Architecture: Keep runtime validation owned by wf_core and persisted run inspection; the web layer only projects known JSON Schema and replay payload data into display fields. Add a small pure projection module, then render it through one approval component used by the typed interrupt panel and the chat approval event. The current replay has a loose resume schema, so the UI must show outcome buttons plus the actual recorded resume payload instead of pretending fields exist.

Tech Stack: React 19, TypeScript, Vitest, Testing Library, Valibot for existing replay decoding, CSS modules by convention through existing presentation stylesheets.

Global Constraints

  • Do not implement JSON Schema validation in the web UI; runtime validation already lives in the workflow engine.
  • Do not add a form library or component library in this slice.
  • Do not replace the chat surface in this slice; make the approval component reusable by the later AI Elements/chat-library work.
  • Keep Scene 10 readable at 720p and avoid adding a modal for the approval form.
  • Use submitted/cancelled outcome language, not approved/denied, when describing workflow resume outcomes.
  • Raw schema evidence may remain available, but it must not be the primary approval visual.
  • Add comments around non-obvious fallback logic, especially when projecting fields from a loose schema plus replay payload.

File Structure

  • Create web/apps/console/src/presentation/approval/schema-approval-model.ts
    • Pure projection helpers from schema/payload/outcomes to display rows.
  • Create web/apps/console/src/presentation/approval/schema-approval-model.test.ts
    • Unit tests for explicit schema fields, loose-object fallback, arrays, booleans, and unknown schemas.
  • Create web/apps/console/src/presentation/approval/SchemaApprovalSurface.tsx
    • Reusable approval UI: heading, outcome buttons, projected fields, payload preview, status text.
  • Create web/apps/console/src/presentation/approval/SchemaApprovalSurface.test.tsx
    • Component tests for buttons, field rendering, loose schema copy, cancelled/submitted states.
  • Modify web/apps/console/src/presentation/demo-workflow-model.ts
    • Extend the interrupt projection with request schema, resume payload preview, and resume outcome.
  • Modify web/apps/console/src/presentation/InterruptContractPreview.tsx
    • Use SchemaApprovalSurface for approval mode; keep raw schema compact for preview mode.
  • Modify web/apps/console/src/presentation/DemoWorkflowScene.tsx
    • Pass the run_resume event into the interrupt contract projection.
  • Modify web/apps/console/src/presentation/DemoWorkflowScene.test.tsx
    • Update assertions away from raw-schema-first approval and toward form/payload/outcome evidence.
  • Modify web/apps/console/src/demo/agent/events.ts
    • Add optional approval contract data to approval-request parts without importing presentation code.
  • Modify web/apps/console/src/demo/agent/preparedRecipeDriver.ts
    • Attach replay-derived approval contract data to the resumeIssueReview approval request.
  • Modify web/apps/console/src/presentation/OperatorChat.tsx
    • Render SchemaApprovalSurface inside approval-request parts when approval data is present; fall back to current buttons otherwise.
  • Modify web/apps/console/src/presentation/OperatorChat.test.tsx
    • Assert schema approval renders in chat and still calls approve/cancel handlers.
  • Modify web/apps/console/src/presentation/styles/demo-workflow.css
    • Add approval surface styles and remove raw-schema dominance in approval mode.
  • Modify docs/current_roadmap.md
    • Mark this schema approval slice completed when implementation is done and renumber later items.

Task 1: Pure Schema Approval Projection

Files:

  • Create: web/apps/console/src/presentation/approval/schema-approval-model.ts
  • Create: web/apps/console/src/presentation/approval/schema-approval-model.test.ts

Interfaces:

  • Produces:
export type SchemaApprovalFieldKind = "string" | "number" | "boolean" | "array" | "object" | "unknown";

export type SchemaApprovalField = {
  readonly name: string;
  readonly label: string;
  readonly kind: SchemaApprovalFieldKind;
  readonly required: boolean;
  readonly description: string | null;
  readonly valuePreview: string | null;
};

export type SchemaApprovalModel = {
  readonly hasExplicitFields: boolean;
  readonly fields: ReadonlyArray<SchemaApprovalField>;
  readonly payloadPreview: ReadonlyArray<{ readonly key: string; readonly value: string }>;
  readonly outcomes: ReadonlyArray<string>;
};

export type BuildSchemaApprovalModelInput = {
  readonly schema: unknown;
  readonly payload: unknown;
  readonly outcomes: ReadonlyArray<string>;
};

export const buildSchemaApprovalModel = (input: BuildSchemaApprovalModelInput): SchemaApprovalModel;

  • Consumes: no project runtime APIs; this is a pure projection helper.

  • Step 1: Write the failing projection tests

Create web/apps/console/src/presentation/approval/schema-approval-model.test.ts:

});
  • Step 2: Run the tests to verify they fail

Run:

  • Step 4: Run the projection tests

Run:

pnpm --filter @lda/console test -- src/presentation/approval/schema-approval-model.test.ts

  min-width: 0;
  padding: 0.85rem;
  border: 1px solid color-mix(in oklch, var(--accent-amber) 48%, var(--stage-line));
  border-radius: 0.85rem;

  • Step 5: Run the component tests

Run:

pnpm --filter @lda/console test -- src/presentation/approval

Expected: PASS.

  • Step 6: Commit
git add web/apps/console/src/presentation/approval web/apps/console/src/presentation/styles/demo-workflow.css
git commit -m "feat: add schema approval surface"

Task 3: Wire Scene 10 Approval To Replay Payload

Files:

  • Modify: web/apps/console/src/presentation/demo-workflow-model.ts
  • Modify: web/apps/console/src/presentation/InterruptContractPreview.tsx
  • Modify: web/apps/console/src/presentation/DemoWorkflowScene.tsx
  • Modify: web/apps/console/src/presentation/DemoWorkflowScene.test.tsx

Interfaces:

  • Consumes: SchemaApprovalSurface

  • Produces: InterruptContractPresentation with request schema and resume payload.

  • Step 1: Write failing scene assertions

Modify web/apps/console/src/presentation/DemoWorkflowScene.test.tsx:

it("shows a schema approval surface for the approval beat instead of raw schema as the primary visual", () => {
  render(<DemoWorkflowScene beatId="approval" recording={recording} />);

  const approval = screen.getByRole("group", { name: /issue review resume/i });
  expect(within(approval).getByText("Schema-backed decision")).toBeInTheDocument();
  expect(within(approval).getByText("selected_issue_ids")).toBeInTheDocument();
  expect(within(approval).getByText("[\"risk-1\"]")).toBeInTheDocument();
  expect(within(approval).getByRole("button", { name: /submit/i })).toBeDisabled();
  expect(within(approval).getByRole("button", { name: /cancel/i })).toBeDisabled();
});

it("keeps raw resume schema visible only in interrupt preview mode", () => {
  const { rerender } = render(<DemoWorkflowScene beatId="interrupt" recording={recording} />);
  expect(screen.getByText("Resume schema")).toBeInTheDocument();

  rerender(<DemoWorkflowScene beatId="approval" recording={recording} />);
  expect(screen.queryByText("Resume schema")).not.toBeInTheDocument();
});

Make sure this test imports within from @testing-library/react.

  • Step 2: Run the tests to verify they fail

Run:

pnpm --filter @lda/console test -- src/presentation/DemoWorkflowScene.test.tsx

Expected: FAIL because approval mode still renders InterruptContractPreview with raw schema only.

  • Step 3: Extend the presentation contract

Modify web/apps/console/src/presentation/demo-workflow-model.ts:

const InterruptProjectionSchema = v.looseObject({
  kind: v.string(),
  outcomes: v.optional(v.array(v.string())),
  request_schema: v.optional(v.unknown()),
  resume_schema: v.optional(v.unknown()),
});

const ResumeParamsSchema = v.looseObject({
  resume_payload: v.optional(v.unknown()),
  resume_outcome: v.optional(v.string()),
});

Update InterruptContractPresentation:

export type InterruptContractPresentation = {
  readonly kind: string;
  readonly outcomes: ReadonlyArray<string>;
  readonly requestSchema: unknown;
  readonly resumeSchema: unknown;
  readonly resumePayloadPreview: unknown;
  readonly resumeOutcome: string | null;
  readonly runId: string | null;
};

Update projectInterruptContract:

export const projectInterruptContract = (
  event: DemoEvent,
  resumeEvent?: DemoEvent | null,
): InterruptContractPresentation | null => {
  const interrupt = decodeInterpretation(event)?.interrupt;
  if (!interrupt || !interrupt.outcomes || interrupt.resume_schema === undefined) return null;
  const decodedResumeParams = v.safeParse(ResumeParamsSchema, resumeEvent?.params);
  const resumeParams = decodedResumeParams.success ? decodedResumeParams.output : null;
  return {
    kind: interrupt.kind,
    outcomes: interrupt.outcomes,
    requestSchema: interrupt.request_schema ?? null,
    resumeSchema: interrupt.resume_schema,
    resumePayloadPreview: resumeParams?.resume_payload ?? null,
    resumeOutcome: resumeParams?.resume_outcome ?? null,
    runId: event.resultingIds.runId,
  };
};
  • Step 4: Pass the resume event from the demo scene

Modify web/apps/console/src/presentation/DemoWorkflowScene.tsx:

const runStart = recording.events.find((event) => event.stage === "run_start") ?? null;
const runResume = recording.events.find((event) => event.stage === "run_resume") ?? null;
const contract = runStart ? projectInterruptContract(runStart, runResume) : null;
  • Step 5: Render approval surface in approval mode

Modify web/apps/console/src/presentation/InterruptContractPreview.tsx:

import { SchemaApprovalSurface } from "./approval/SchemaApprovalSurface.js";

Inside the component body, before the raw schema block:

{mode === "approval" ? (
  <SchemaApprovalSurface
    title={`${contract.kind} resume`}
    schema={contract.resumeSchema}
    payload={contract.resumePayloadPreview}
    outcomes={contract.outcomes}
    runId={contract.runId}
  />
) : (
  <div className="interrupt-contract-preview__schema">
    <span>Resume schema</span>
    <pre><code>{formatJson(contract.resumeSchema)}</code></pre>
  </div>
)}

Keep the header and persisted-run summary. The approval mode can show both the surrounding interrupt metadata and the approval surface, but not the raw schema block as the main visual.

  • Step 6: Run scene tests

Run:

pnpm --filter @lda/console test -- src/presentation/DemoWorkflowScene.test.tsx src/presentation/InterruptContractPreview.test.tsx

If InterruptContractPreview.test.tsx does not exist, run only DemoWorkflowScene.test.tsx.

Expected: PASS.

  • Step 7: Commit
git add web/apps/console/src/presentation/demo-workflow-model.ts web/apps/console/src/presentation/InterruptContractPreview.tsx web/apps/console/src/presentation/DemoWorkflowScene.tsx web/apps/console/src/presentation/DemoWorkflowScene.test.tsx
git commit -m "feat: show schema approval in demo interrupt"

Task 4: Attach Approval Data To Chat Approval Requests

Files:

  • Modify: web/apps/console/src/demo/agent/events.ts
  • Modify: web/apps/console/src/demo/agent/events.test.ts
  • Modify: web/apps/console/src/demo/agent/preparedRecipeDriver.ts
  • Modify: web/apps/console/src/demo/agent/preparedRecipeDriver.test.ts
  • Modify: web/apps/console/src/presentation/OperatorChat.tsx
  • Modify: web/apps/console/src/presentation/OperatorChat.test.tsx

Interfaces:

  • Produces:
export type AgentApprovalContract = {
  readonly kind: string;
  readonly outcomes: ReadonlyArray<string>;
  readonly resumeSchema: unknown;
  readonly resumePayloadPreview: unknown;
  readonly runId: string | null;
};

Then:

| {
    readonly type: "approval-request";
    readonly callId: string;
    readonly name: AgentToolName;
    readonly prompt: string;
    readonly contract?: AgentApprovalContract | undefined;
  }

  • Consumes: SchemaApprovalSurface.

  • Step 1: Add event tests for optional approval contract

Modify web/apps/console/src/demo/agent/events.test.ts:

it("creates approval request parts with optional contract data", () => {
  const part = approvalRequestPart(
    "call-1",
    "resumeIssueReview",
    "Approve?",
    {
      kind: "issue_review",
      outcomes: ["submitted", "cancelled"],
      resumeSchema: { type: "object" },
      resumePayloadPreview: { selected_issue_ids: ["risk-1"] },
      runId: "run_recorded_lda_report",
    },
  );

  expect(part).toMatchObject({
    type: "approval-request",
    contract: {
      kind: "issue_review",
      runId: "run_recorded_lda_report",
    },
  });
});
  • Step 2: Update event types and constructor

Modify web/apps/console/src/demo/agent/events.ts:

export type AgentApprovalContract = {
  readonly kind: string;
  readonly outcomes: ReadonlyArray<string>;
  readonly resumeSchema: unknown;
  readonly resumePayloadPreview: unknown;
  readonly runId: string | null;
};

Update the union member and constructor:

| {
    readonly type: "approval-request";
    readonly callId: string;
    readonly name: AgentToolName;
    readonly prompt: string;
    readonly contract?: AgentApprovalContract | undefined;
  }

export const approvalRequestPart = (
  callId: string,
  name: AgentToolName,
  prompt: string,
  contract?: AgentApprovalContract,
): AgentMessagePart => ({
  type: "approval-request",
  callId,
  name,
  prompt,
  contract,
});
  • Step 3: Attach replay-derived contract in prepared driver

Modify web/apps/console/src/demo/agent/preparedRecipeDriver.ts near the runStart / resume lookup:

const interrupt = runStart?.interpreted && typeof runStart.interpreted === "object"
  && "interrupt" in runStart.interpreted
  ? runStart.interpreted.interrupt
  : null;
const resumePayload = resume?.params && typeof resume.params === "object" && "resume_payload" in resume.params
  ? resume.params.resume_payload
  : null;

Add a local helper if type-checking needs narrowing:

const approvalContract = isObject(interrupt) && Array.isArray(interrupt.outcomes)
  ? {
      kind: typeof interrupt.kind === "string" ? interrupt.kind : "issue_review",
      outcomes: interrupt.outcomes.filter((entry): entry is string => typeof entry === "string"),
      resumeSchema: "resume_schema" in interrupt ? interrupt.resume_schema : { type: "object" },
      resumePayloadPreview: resumePayload,
      runId,
    }
  : undefined;

Then update the approval request:

approvalRequestPart(
  callId,
  step.toolName,
  "Approve resuming the workflow run with the selected issues?",
  approvalContract,
),

Add a small isObject helper in this file if needed:

const isObject = (value: unknown): value is Record<string, unknown> =>
  typeof value === "object" && value !== null && !Array.isArray(value);
  • Step 4: Add driver test assertion

Modify web/apps/console/src/demo/agent/preparedRecipeDriver.test.ts in the approval-request test:

const approvalPart = messages
  .flatMap((message) => message.parts)
  .find((part) => part.type === "approval-request");
expect(approvalPart).toMatchObject({
  type: "approval-request",
  contract: {
    kind: "issue_review",
    runId: "run_recorded_lda_report",
  },
});
  • Step 5: Render schema approval inside chat

Modify web/apps/console/src/presentation/OperatorChat.tsx:

import { SchemaApprovalSurface } from "./approval/SchemaApprovalSurface.js";

Replace the approval-request branch with:

case "approval-request":
  return (
    <div key={key} className="chat-tool-part chat-tool-part--approval">
      <span>Approval required</span>
      <code>{part.name}</code>
      <p>{part.prompt}</p>
      {part.contract ? (
        <SchemaApprovalSurface
          title={`${part.contract.kind} resume`}
          schema={part.contract.resumeSchema}
          payload={part.contract.resumePayloadPreview}
          outcomes={part.contract.outcomes}
          runId={part.contract.runId}
          onSubmit={onApprove}
          onCancel={onDeny}
        />
      ) : (
        <div className="chat-approval-actions">
          <button type="button" onClick={onApprove} disabled={!onApprove}>Approve</button>
          <button type="button" onClick={onDeny} disabled={!onDeny}>Deny</button>
        </div>
      )}
    </div>
  );
  • Step 6: Update chat tests

Modify web/apps/console/src/presentation/OperatorChat.test.tsx approval test to include contract and expect submit/cancel:

expect(screen.getByRole("group", { name: /issue review resume/i })).toBeInTheDocument();
fireEvent.click(screen.getByRole("button", { name: /submit/i }));
fireEvent.click(screen.getByRole("button", { name: /cancel/i }));
expect(onApprove).toHaveBeenCalledTimes(1);
expect(onDeny).toHaveBeenCalledTimes(1);

Keep a fallback test for approval requests without contract, because live AI SDK drivers may not provide this immediately.

  • Step 7: Run focused agent/chat tests

Run:

pnpm --filter @lda/console test -- src/demo/agent src/presentation/OperatorChat.test.tsx src/presentation/approval

Expected: PASS.

  • Step 8: Commit
git add web/apps/console/src/demo/agent web/apps/console/src/presentation/OperatorChat.tsx web/apps/console/src/presentation/OperatorChat.test.tsx web/apps/console/src/presentation/approval
git commit -m "feat: render schema approval in chat"

Task 5: Verification, Roadmap, And Visual Smoke

Files:

  • Modify: docs/current_roadmap.md
  • Move after completion: docs/superpowers/plans/2026-07-09-schema-approval-surface.md -> docs/historical/superpowers/plans/2026-07-09-schema-approval-surface.md

Interfaces:

  • Consumes all previous task outputs.

  • Produces final documented slice status.

  • Step 1: Run presentation-focused tests

Run:

pnpm --filter @lda/console test -- src/presentation src/demo/agent

Expected: PASS.

  • Step 2: Run broad web verification

Run:

pnpm --dir web test
pnpm --dir web typecheck
pnpm --dir web build

Expected:

  • Tests pass.

  • Typecheck clean.

  • Build passes with only the known Vite chunk-size warning if it appears.

  • Step 3: Capture visual smoke screenshots

With pnpm dev running, capture these routes at 1280x720:

http://127.0.0.1:5173/present#scene/interrupt-evidence/approval
http://127.0.0.1:5173/present#scene/interrupt-evidence/resume
http://127.0.0.1:5173/present#scene/workflow-demo/interrupt

Expected:

  • Approval beat shows the schema approval surface and recorded resume payload.

  • Interrupt beat still shows raw resume schema proof.

  • Buttons are visible but disabled in Scene 10 unless the chat approval event owns handlers.

  • Step 4: Update roadmap

In docs/current_roadmap.md:

  • Change implementation order item 15 from future to completed.
  • Add implementation link to historical/superpowers/plans/2026-07-09-schema-approval-surface.md.
  • Keep chat surface replacement as a later item unless it was fully replaced; this slice only improves approval rendering inside existing chat.

Use wording like:

15. Completed: schema approval surface for typed interrupt/resume decisions.
    Scene 10 and prepared-agent approval requests now render schema/payload
    approval UI instead of raw `{ "type": "object" }` as the primary product
    proof. Implementation:
    [`schema approval surface`](historical/superpowers/plans/2026-07-09-schema-approval-surface.md).
  • Step 5: Archive the plan

Run:

git mv docs/superpowers/plans/2026-07-09-schema-approval-surface.md docs/historical/superpowers/plans/2026-07-09-schema-approval-surface.md
  • Step 6: Commit
git add docs/current_roadmap.md docs/historical/superpowers/plans/2026-07-09-schema-approval-surface.md
git commit -m "docs: complete schema approval surface"

Self-Review Checklist

  • No task asks the worker to implement JSON Schema validation in React.
  • Scene 10 approval no longer makes raw { "type": "object" } the primary visual.
  • Loose-schema fallback uses actual recorded resume payload and has a code comment explaining why.
  • Chat approval request still works without contract data.
  • The component has explicit submit/cancel labels, but workflow outcome copy remains submitted/cancelled.
  • Tests cover projection, component rendering, Scene 10 integration, and chat integration.
  • Roadmap points to historical/** after completion.
