# Apple Silicon RB-08 runbook

Verification of RB-08: does Lumotia's `NSProcessInfo.beginActivityWithOptions` call actually prevent App Nap on M-series hardware? This takes roughly 10 minutes on a machine that already has the app installed.

## Prerequisites

- M-series Mac (M1, M2, M3, or M4 — any chip revision)
- Latest macOS release
- Lumotia v0.1.0 `.dmg` installed via the Gatekeeper "Open Anyway" flow (see `docs/release/install-warnings.md`)

---

## Step 1 — Baseline

Open Activity Monitor (Spotlight: `Activity Monitor`). Click the Energy tab. Find Lumotia. If the App Nap column is missing, right-click the column header bar and enable it.

Open Lumotia, bring its window to the front. Confirm App Nap shows **No** while the window is focused. This is the expected baseline.

---

## Test 1 — Focused recording (60 seconds)

Keep the Lumotia window in the foreground. Start a recording. Speak for 60 seconds. Stop.

**Expected:** Full 60-second transcript. App Nap stayed **No**.

**Failure:** Transcript shorter than what was spoken, or transcription did not complete.

---

## Test 2 — Backgrounded recording (60 seconds)

Start a recording. Immediately press Command-Tab to switch to another app. Speak for 60 seconds while Lumotia is in the background. Switch back. Stop the recording.

While waiting, watch Activity Monitor: does App Nap flip to **Yes** for Lumotia?

**Expected (RB-08 mitigated):** Full 60-second transcript. App Nap stayed **No** throughout.

**Failure (RB-08 not mitigated):** Transcript contains only the first few seconds of speech. App Nap column flipped to Yes during the background period.

---

## Test 3 — Long backgrounded session (5 minutes)

Same as Test 2 but leave Lumotia backgrounded for 5 minutes.

**Expected:** Full 5-minute transcript.

**Failure:** Transcript truncated. Note the approximate cutoff in seconds.

---

## Recording the outcome

**All three tests pass — RB-08 mitigated:**

1. Tick the RB-08 item in `docs/release/v0.1-checklist.md`.
2. Open `KNOWN-ISSUES.md`, find KI-01, update its status to "fixed in v0.1", and append the test results + Mac model + macOS version.

**Test 2 or Test 3 fails — RB-08 not mitigated:**

1. Leave the RB-08 checklist item unchecked.
2. In `docs/release/v0.1-known-limitations.md`, update the macOS row to name the tested hardware/OS and state that throttling was observed when backgrounded.
3. Add the workaround: "Keep the Lumotia window focused during long dictation sessions. System-wide override: `defaults write NSGlobalDomain NSAppSleepDisabled -bool YES` (revert with `-bool NO` when done)."
4. Append the failure details to `KNOWN-ISSUES.md` KI-01.

## Reporting format for KNOWN-ISSUES.md

Append this block to the KI-01 entry:

```
RB-08 verification — [date]
Mac model: [e.g. MacBook Pro M2 Max, 2023]
macOS: [e.g. 15.3.2]
Test 1 (focused, 60s): PASS / FAIL
Test 2 (backgrounded, 60s): PASS / FAIL — App Nap column: [Yes / No / fluctuated]
Test 3 (backgrounded, 5min): PASS / FAIL — transcript cutoff at approx [N] seconds
Overall: MITIGATED / NOT MITIGATED
```
