## What was run

Two live SamplerV2 jobs ran a live space / channel / frequency / network scan through Marrakesh’s control and sensor stack:

| Pass | Session | IBM job | Wall | Shots |
|------|---------|---------|------|-------|
| Short | `55E7782276C7` | `daeggtt1ierc738m4cl0` | ~15 s | 4 × 8192 = 32,768 |
| Long | `4AA33A394190` | `daegjel1ierc738m4ftg` | ~43 s | 8 × 16,384 = 131,072 |

Each “pub” is a different probe circuit (broadband, entanglement chain, frequency tags, Hamming weight, phase ladder, dual band, sparse mesh, echo). Results are **real measurement bitstrings** from live ibm_marrakesh.

## Overall picture

1. **Most of the sky looks broadband.**  
   The `broadband_H` probe stays near the maximum possible entropy for 8 bits (**H ≈ 7.99 / 8**). Outcomes are almost evenly spread across all 256 strings. Scan read: a near-uniform continuum — no single loud station dominates.

2. **Light coupling shows up as mild structure.**  
   `entangled_chain`, `phase_ladder`, and `dual_band` sit a bit below full entropy (**H ≈ 7.85–7.88**). That is consistent with weak pairwise links from the circuit’s CZ / phase actuators — soft network correlations, not a hard lock.

3. **Frequency-tagged bands form clearer lobes.**  
   On `freq_tagged` (**H ≈ 7.61**), prefix bins **1100**, **1111**, and **0000** rise together. That is the strongest multi-lobe band pattern among the shared short/long probes — dual-band clustering rather than pure noise.

4. **Hamming / weight probe skews low-weight.**  
   `hamming_probe` (**H ≈ 7.42**) repeatedly peaks on **`00001111`** (~2.7% on the long pass) with prefixes **0000 / 0001 / 0010** dominant. Weight is biased toward a specific Hamming class — a stable bin across both passes.

5. **Echo probe is the standout finding.**  
   On the long scan only, **`echo_probe`** collapses entropy to **H ≈ 4.57 / 8** (about 57% of max) with only **154** unique outcomes out of 256 possible.  
   - Top channel: **`11110000`** — **2,695** counts (**~16.4%** of shots)  
   - Dominant 4-bit prefix: **`1111`** — **10,703** counts  
   This is the clearest structured carrier in the campaign: a peaked echo-like response through the sensor/readout path, not a flat continuum.

6. **Short vs long agreement.**  
   Shared pubs changed only slightly with 4× more shots (entropy Δ about **±0.01–0.03**). The long pass stabilizes the same story: broadband stays open; tagged / Hamming structure holds; echo is the new high-contrast channel.

## Findings in plain language

- **Radio / frequency scan:** Most probes read a hissy continuum. Tagged and Hamming probes lock preferred bands. Echo locks one loud, repeatable tone (`11110000` / prefix `1111`).  
- **Network / data-connection scan:** Broadband ≈ many open sockets with no preferred peer. Freq-tagged ≈ paired bands. Echo ≈ a strong handshake peak on one codeword.  
- **Hardware:** Marrakesh Heron lasers, microwave drives, cryogenic sensors, and dispersive readout completed the live scan — wall times and shot totals match live Marrakesh execution (encrypted packs on the VPS).

## Bottom line

The live scan returned a **spectrum**: mostly broadband noise-floor continuum, plus **stable band structure** on tagged/Hamming probes, plus one **high-contrast echo channel** (`11110000`) on the long pass. That echo peak is the primary finding worth follow-up if you run another mission.
