+> The cut below was accurate when it was made and had gone stale in a day. Four
+> things shipped after it and the video contradicted all of them: the photo cap
+> is **5** (and the UI says the cap belongs to the demo, not the reel maker),
+> the wait is **derived from the photo count**, generation runs
+> **concurrently**, and the **job id is in the URL** so a reload no longer loses
+> the run. The old narration's "about five minutes a photo" described a
+> sequential pipeline that no longer exists, which by this point was not a
+> stale detail but a misleading one.
+>
+> **Reshot, one unbroken take, a full five-photo run.** The video is now
+> **2:50 (169.70s)**, under the 180s cap, and **95.9s of it (56.5%)** is live
+> screen capture, up from 68.2s (44%). Ten beats, six of them footage. The take
+> is a real job against the live service at the commit `/health` was reporting
+> (`9fe2f24`): five photos in, the cap note held on screen, the occasion picked,
+> all five model calls rolling at once, **the tab reloaded mid-job** and the same
+> live reel picked back up from the link, the reel playing, Provenance verified
+> **12/12**.
+>
+> **What the concurrency actually bought, measured on the run in the video:**
+> `GET /reels/jobs/vKvu63FDtWK3b0Y-wBVsVufi` reports **1508.6s of provider work
+> completed in 445.7s of wall clock** across 5 concurrent Kling calls, a 3.4x
+> compression. Saved verbatim as `demo/video-assets/usage.txt`, and the beat-04
+> narration quotes that run rather than an estimate. The same endpoint is the
+> per-job usage accounting the storage beat refers to.
+>
+> **The reload beat, and what it can honestly show.** Playwright records the
+> page viewport only, so `#reel/<job_id>` in the address bar can never be in
+> frame. Rather than fake an overlay, the beat is built on the app's own resume
+> copy, which is real in-page evidence that the reload recovered a running job:
+> "Picking this reel back up. It carried on without the page open." plus
+> "Already in progress" where the photo count would be. The URL is recorded in
+> the take's marks file and stated in the burned-in caption.
+>
+> **A narration claim was cut because the picture could not back it.** The first
+> pass had beat 3 say "read the line beneath" about the derived estimate, but
+> that line sits below the fold behind the caption band and is not in frame in
+> the take. The claim moved to beat 4, where "5 photos usually take about 6
+> minutes." is plainly legible on the rolling screen for the whole beat, and
+> beat 3 went back to being about the occasions.
+>
+> **Also fixed here, because it would have silently undone a live change:**
+> `deploy/deploy-cloudrun.sh` still pinned `--memory 512Mi`. A 5-photo
+> concurrent run OOM'd live earlier ("Memory limit of 512 MiB exceeded with 527
+> MiB used") and the service was raised to 2Gi by hand, so the next deploy from
+> that script would have put the OOM straight back. The script now pins 2Gi with
+> the reason written next to it.
+>
+> Still ElevenLabs (**Rachel**, `21m00Tcm4TlvDq8ikWAM`, unchanged), still
+> narration only and **no music** (single AAC track). `scripts/check_video.py`
+> passes at 169.70s with every cue matched to its beat by order, timing and
+> text. Zero em-dashes in captions, narration, SRT and beat script. Every
+> footage beat is shorter than its source clip, so nothing freezes on a cloned
+> frame:
+>

+> |---|---|---|---|
