+# Presentation Live/Replay Truth 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:** Make presentation mode explicitly distinguish replay evidence, configured live target, reachable live target, active live run, and replay fallback.
+
+**Architecture:** Add a small presentation target-status model/hook, render it in the presentation footer, and route chat run labels through that status. Keep direct scene hashes replay-backed until the operator intentionally starts live execution.
+
+**Tech Stack:** React 19, TypeScript, Vitest, Testing Library, existing console RPC operation layer, existing presentation footer/chat components.
+
+## Global Constraints
+
+- Do not add a new JSON-RPC transport if the existing console operation layer can call `workflow.health`.
+- Do not change `/console` connection behavior.
+- Direct scene hashes must remain replay-backed and ready.
+- Do not say "live run active" before the operator starts the timeline in live mode.
+- Health check failure must fall back to replay wording, not crash the presentation.
+- Keep UI compact; this is a truth badge, not a new hero panel.
+
+---
+
+## File Structure
+
+- Create `web/apps/console/src/presentation/presentation-target-status.ts`
+  - Pure status model and copy helpers.
+- Create `web/apps/console/src/presentation/presentation-target-status.test.ts`
+  - Tests status derivation.
+- Create `web/apps/console/src/presentation/usePresentationTargetStatus.ts`
+  - Hook that probes target health and combines it with demo timeline state.
+- Create `web/apps/console/src/presentation/usePresentationTargetStatus.test.tsx`
+  - Tests health success/failure and active live state.
+- Create `web/apps/console/src/presentation/PresentationTruthBadge.tsx`
+  - Compact footer badge.
+- Create `web/apps/console/src/presentation/PresentationTruthBadge.test.tsx`
+  - Tests labels and data-state attributes.
+- Modify `web/apps/console/src/presentation/PresentationRoute.tsx`
+  - Uses the hook and passes status to stage/chat/footer.
+- Modify `web/apps/console/src/presentation/PresentationStage.tsx`
+  - Threads status to footer and chat.
+- Modify `web/apps/console/src/presentation/PresentationFooter.tsx`
+  - Renders `PresentationTruthBadge`.
+- Modify `web/apps/console/src/presentation/OperatorChat.tsx`
+  - Uses status-aware run label/copy.
+- Modify `web/apps/console/src/demo/agent/timelineAgent.ts`
+  - Accepts status-derived mode/copy or receives enabled label from route.
+- Modify `web/apps/console/src/presentation/presentation.css`
+  - Adds compact badge styles.

+### Task 1: Add pure presentation target status model
+
+**Files:**
+
+- Create: `web/apps/console/src/presentation/presentation-target-status.ts`
+- Create: `web/apps/console/src/presentation/presentation-target-status.test.ts`

+    readonly probe: TargetProbeState;
+    readonly liveActive: boolean;
+    readonly failureReason?: string | undefined;
+  }): PresentationTargetHealth;
+  ```
+
+- [ ] **Step 1: Write failing tests**
+
+  Create `web/apps/console/src/presentation/presentation-target-status.test.ts`:
+
+  ```ts
+  import { describe, expect, it } from "vitest";
+  import { presentationTargetHealth } from "./presentation-target-status.js";

+
+- [ ] **Step 2: Run failing tests**
+
+  ```bash
+  pnpm --dir web --filter @lda/console test -- src/presentation/presentation-target-status.test.ts
+  ```
+
+  Expected: FAIL because the model file does not exist.
+
+- [ ] **Step 3: Implement model**
+
+  Create `web/apps/console/src/presentation/presentation-target-status.ts`:
+
+  ```ts
+  export type PresentationTargetHealth =
+    | { readonly kind: "replay"; readonly label: string; readonly detail: string }

+- [ ] **Step 4: Run tests**
+
+  ```bash
+  pnpm --dir web --filter @lda/console test -- src/presentation/presentation-target-status.test.ts

+### Task 2: Add target health hook
+
+**Files:**
+
+- Create: `web/apps/console/src/presentation/usePresentationTargetStatus.ts`
+- Create: `web/apps/console/src/presentation/usePresentationTargetStatus.test.tsx`
+
+**Interfaces:**
+
+- Consumes:
+  - `PresentationTargetState` from `live-target.ts`
+  - `DemoTimelineController["state"]`
+  - Existing operation call path if available.
+- Produces:
+
+  ```ts
+  export const usePresentationTargetStatus = (
+    targetState: PresentationTargetState,
+    demoState: DemoTimelineState,
+  ): PresentationTargetHealth;
+  ```
+
+- [ ] **Step 1: Inspect existing RPC operation helper**
+
+  Run:
+
+  ```bash
+  rg -n "workflow.health|callOperation|OperationName" web/apps/console/src web/packages/rpc/src
+  ```
+
+  Use the existing helper that the console already uses for lifecycle/demo calls.
+  Do not create a separate fetch transport if `callOperation` can call
+  `workflow.health`.
+
+- [ ] **Step 2: Write failing hook tests**
+
+  Create `web/apps/console/src/presentation/usePresentationTargetStatus.test.tsx`.
+  Mock the existing call helper. If it is `callOperation`, use:
+
+  ```tsx
+  import { renderHook, waitFor } from "@testing-library/react";
+  import { beforeEach, describe, expect, it, vi } from "vitest";
+  import { callOperation } from "../connection/api.js";
+  import { initialDemoTimelineState } from "../demo/timeline/reducer.js";

+      await waitFor(() => expect(result.current.kind).toBe("failed"));
+      expect(result.current.label).toBe("Replay fallback");
+    });
+  });
+  ```
+
+  Adjust operation response fields to match existing `callOperation` types.
+
+- [ ] **Step 3: Run failing tests**
+
+  ```bash
+  pnpm --dir web --filter @lda/console test -- src/presentation/usePresentationTargetStatus.test.tsx
+  ```
+
+  Expected: FAIL because the hook does not exist.
+
+- [ ] **Step 4: Implement hook**
+
+  Create `web/apps/console/src/presentation/usePresentationTargetStatus.ts`:
+
+  ```ts
+  import { useEffect, useState } from "react";

+  };
+  ```
+
+  If `callOperation` takes a different parameter shape, adapt to the existing
+  function signature and update the test mock accordingly.

+      <span>{status.detail}</span>
+    </aside>
+  );
+  ```
+
+- [ ] **Step 4: Thread status through stage/footer**
+
+  In `PresentationRoute.tsx`, import and call hook:
+
+  ```ts
+  import { usePresentationTargetStatus } from "./usePresentationTargetStatus.js";
+
+  const targetStatus = usePresentationTargetStatus(presentationTarget, demo.state);
+  ```
+
+  Pass to `PresentationStage`.
+
+  In `PresentationStage.tsx`, add prop:
+
+  ```ts
+  readonly targetStatus: PresentationTargetHealth;
+  ```
+
+  Pass to `PresentationFooter`.
+
+  In `PresentationFooter.tsx`, add prop:
+
+  ```ts
+  readonly targetStatus: PresentationTargetHealth;
+  ```
+
+  Render:
+
+  ```tsx
+  <PresentationTruthBadge status={targetStatus} />
+  ```
+
+  Place it between `SceneProgress` and `EvidenceReceipt`.
+
+- [ ] **Step 5: Add compact CSS**

+### Task 4: Align chat copy and run labels with status
+
+**Files:**
+
+- Modify: `web/apps/console/src/demo/agent/timelineAgent.ts`
+- Modify: `web/apps/console/src/demo/agent/timelineAgent.test.tsx`
+- Modify: `web/apps/console/src/presentation/OperatorChat.tsx`
+- Modify: `web/apps/console/src/presentation/OperatorChat.test.tsx`
+
+**Interfaces:**
+
+- Consumes:
+  - `PresentationTargetHealth`
+- Produces:
+  - Chat run label and intro copy do not overclaim live availability.
+
+- [ ] **Step 1: Add tests for status-driven labels**
+
+  In `timelineAgent.test.tsx`, add:
+
+  ```tsx
+  it("uses replay label when live target failed", () => {
+    const demo = demoController();
+    const { result } = renderHook(() =>
+      useTimelineAgent(demo, {
+        mode: "replay",

+        expect.objectContaining({ text: expect.stringMatching(/Replay fallback/i) }),
+      ]),
+    );
+  });
+  ```
+
+  This intentionally changes `useTimelineAgent` signature from `(demo, modeLabel)`
+  to `(demo, options)`.
+
+- [ ] **Step 2: Run failing test**
+
+  ```bash
+  pnpm --dir web --filter @lda/console test -- src/demo/agent/timelineAgent.test.tsx
+  ```
+
+  Expected: FAIL because signature still uses `modeLabel`.
+
+- [ ] **Step 3: Update timeline agent options**
+
+  In `timelineAgent.ts`, change:
+
+  ```ts
+  export type TimelineAgentMode = "live" | "replay";
+  ```
+
+  to:
+
+  ```ts
+  import type { PresentationTargetHealth } from "../../presentation/presentation-target-status.js";
+
+  export type TimelineAgentMode = "live" | "replay";
+
+  export type TimelineAgentOptions = {
+    readonly mode: TimelineAgentMode;
+    readonly status: PresentationTargetHealth;
+  };
+  ```
+
+  Change hook signature:
+
+  ```ts
+  export const useTimelineAgent = (
+    demo: DemoTimelineController,
+    options: TimelineAgentOptions,
+  ): TimelineAgentController => {
+    const modeLabel = options.status.kind === "ready" || options.status.kind === "active"
+      ? options.mode
+      : "replay";
+  ```
+
+  Intro message:
+
+  ```ts
+  const introText = options.status.kind === "ready"
+    ? "Live target is ready. Direct slides still show replay evidence until I start the live run."
+    : options.status.kind === "active"
+      ? "Live run is active. Operations are being sent to the workflow server."
+      : options.status.kind === "failed"
+        ? "Replay fallback is active because the live target is unavailable."
+        : "Replay evidence is active. I can walk through the reviewed recording.";
+  ```
+
+  Run label:
+
+  ```ts
+  const runLabel = modeLabel === "live" ? "Run prepared workflow" : "Run replay walkthrough";
+  ```
+
+  Keep `demo.start(modeLabel)` unchanged.
+
+- [ ] **Step 4: Update route caller**
+
+  In `PresentationRoute.tsx`, pass:
+
+  ```ts
+  const timelineAgent = useTimelineAgent(demo, {
+    mode: presentationTarget.mode === "live" ? "live" : "replay",
+    status: targetStatus,
+  });
+  ```
+
+  Ensure `targetStatus` is defined before `useTimelineAgent`.
+
+- [ ] **Step 5: Run tests**
+
+  ```bash
+  pnpm --dir web --filter @lda/console test -- src/demo/agent/timelineAgent.test.tsx src/presentation/OperatorChat.test.tsx src/presentation/PresentationRoute.test.tsx
+  ```
+
+  Expected: PASS.
+
+- [ ] **Step 6: Commit**
+
+  ```bash
+  git add web/apps/console/src/demo/agent/timelineAgent.ts web/apps/console/src/demo/agent/timelineAgent.test.tsx web/apps/console/src/presentation/PresentationRoute.tsx web/apps/console/src/presentation/OperatorChat.tsx web/apps/console/src/presentation/OperatorChat.test.tsx
+  git commit -m "fix: make chat honest about live replay status"
+  ```
+
+---
+
+### Task 5: Docs, verification, and archive
+
+**Files:**
+
+- Modify: `docs/current_roadmap.md`
+- Move: `docs/superpowers/plans/2026-07-09-presentation-live-replay-truth.md` to `docs/historical/superpowers/plans/2026-07-09-presentation-live-replay-truth.md`
+
+- [ ] **Step 1: Run focused tests**
+
+  ```bash
+  pnpm --dir web --filter @lda/console test -- src/presentation/presentation-target-status.test.ts src/presentation/usePresentationTargetStatus.test.tsx src/presentation/PresentationTruthBadge.test.tsx src/demo/agent/timelineAgent.test.tsx src/presentation/PresentationRoute.test.tsx
+  ```
+
+  Expected: PASS.
+
+- [ ] **Step 2: Run typecheck**
+
+  ```bash
+  pnpm --dir web --filter @lda/console typecheck
+  ```
+
+  Expected: PASS.
+
+- [ ] **Step 3: Run build**
+
+  ```bash
+  pnpm --dir web --filter @lda/console build
+  ```
+
+  Expected: PASS. Existing chunk-size warning is acceptable.
+
+- [ ] **Step 4: Browser smoke**
+
+  With the example server running:
+
+  ```bash
+  uv run wf-rpc-server --config examples/lda_report_workflow/wf.config.json --host 127.0.0.1 --port 8765
+  ```
+
+  Open:
+
+  ```text
+  http://127.0.0.1:5173/present#scene/interrupt-evidence/approval
+  ```
+
+  Expected:
+
+  - Badge says `Live target ready`.
+  - Slide still shows replay approval state.
+  - Chat says direct slides are replay until live run starts.
+
+  Then set session storage target to an invalid URL or use existing replay helper
+  in tests. Expected:
+
+  - Badge says `Replay fallback`.
+  - Chat run label says `Run replay walkthrough`.
+
+- [ ] **Step 5: Update roadmap**
+
+  In `docs/current_roadmap.md`, add completed item:
+
+  ```md
+  20. Completed: presentation live/replay truth surface distinguishes reviewed
+      replay evidence, live target readiness, live active run state, and replay
+      fallback. Design:
+      [`presentation live/replay truth`](superpowers/specs/2026-07-09-presentation-live-replay-truth-design.md).
+      Implementation:
+      [`presentation live/replay truth plan`](historical/superpowers/plans/2026-07-09-presentation-live-replay-truth.md).
+  ```
+
+  Renumber following future items.
+
+- [ ] **Step 6: Archive plan**
+
+  ```bash
+  git mv docs/superpowers/plans/2026-07-09-presentation-live-replay-truth.md docs/historical/superpowers/plans/2026-07-09-presentation-live-replay-truth.md
+  ```
+
+- [ ] **Step 7: Diff hygiene**
+
+  ```bash
+  git diff --check
+  git status --short
+  ```
+
+  Expected: no whitespace errors; only intended files listed.
+
+- [ ] **Step 8: Commit**
+
+  ```bash
+  git add docs/current_roadmap.md docs/historical/superpowers/plans/2026-07-09-presentation-live-replay-truth.md
+  git commit -m "docs: complete presentation live replay truth"
+  ```

+
+## Self-Review
+
+- Spec coverage: health check, badge, chat copy, replay fallback, live active
+  state, tests, and smoke are covered.
+- Placeholder scan: No TODO/TBD placeholders remain.
+- Type consistency: `PresentationTargetHealth`, `TargetProbeState`,
+  `presentationTargetHealth`, and `usePresentationTargetStatus` signatures are
+  consistent.
+- Scope check: This avoids AI Elements/chat replacement and stays focused on
+  truthfulness.
