### 1. STRENGTHS TO PRESERVE
*   **Thematically Anchored Voice Signatures:** Every character adheres strictly to their profile without speaker tags. 
    *   **Marcus:** "Diagnostic: Signal-to-noise ratio is degrading." This perfectly captures his "systems architecture" lens. 
    *   **Sarah:** "Error 404, Leo... City boy not found." This reinforces the "Domestic Siege" and "Status Code" verbal tics from her profile.
    *   **David:** "The sand is drinkin' too fast." The dropped 'g' and cardinal direction "North-by-Northwest" (as per Arthur's legacy influence) are spot-on.
    *   **Leo:** "I'm not on the map anymore." His "Rewiped OS" arc is beautifully realized here.
*   **Tactile World-Building:** The contrast between the "copper-sweet scent of the calf" and the "ozone tang of Marcus’s desperate ingenuity" creates a visceral sense of place.
*   **The "Raven" Drone Encounter:** The mechanical description—"gimbaled sensor array," "microscopic, high-frequency whirs"—effectively builds tension by introducing a high-tech threat into a low-tech sanctuary.
*   **The Closing Hook:** The "flat-line silent" radio is a haunting structural non-negotiable that signals a shift from "hiding" to "isolation."

### 2. MUST-FIX — CONTINUITY
*   **The Julian-Voice Dissonance:** The chapter describes the radio voice as a "high-fidelity render of Julian Avery’s specific, clinical cadence." 
    *   *Error:* Julian’s voice signature (RAG) states he uses tricolons and "clean" as a euphemism, which is present, but the chapter says he "doesn't breathe between sentences." Julian’s profile actually specifies "polished, rhythmic tricolons." 
    *   *Correction:* Adjust the description of the synthetic voice to emphasize the *rhythm* of the tricolons (the rule of three) rather than just a lack of breathing, to align with his "Executive Leadership" profile.
*   **The "Empathy Protocol" Logic:** Marcus states he "air-gapped the empathy protocols" on the server, yet later says "the empathy protocol pings... are acting like a beacon."
    *   *Error:* If a system is truly air-gapped, it cannot broadcast a "ping" traceable by an external drone. 
    *   *Correction:* Clarify that the *Sancutary Node* is air-gapped from the *Grid*, but Marcus is running a "passive leak" or local broadcast to monitor the drone, which is what the Raven picks up.

### 3. MUST-FIX — CLARITY
*   **The Subsonic/Acoustic Transition:**
    *   *Passage:* "a low, subsonic vibration began to thrum... The silence wasn't a fade; it was a cut." 
    *   *Problem:* It is unclear if the "silence" is a technical jammer the drone is using or a natural reaction of the woods. 
    *   *Fix:* Explicitly state that the "cicadas stopped" because of the drone's sonic frequency or a biological "hush" response to a predator, to avoid the reader thinking it’s a writing glitch.
*   **Leo's Humming Resolution:**
    *   *Passage:* "He began to hum... a sound he’d learned from the wind in the cypress."
    *   *Problem:* The logic of *why* this defeats the drone is a bit thin. We need to know if the drone is specifically looking for *rhythmic* human speech/heartbeats.
    *   *Fix:* Add a single internal thought from Marcus or Sarah noting that the drone's "Empathy Signature" logic requires a "Human Standard" rhythm, which Leo’s "Analog" humming disrupts.

### 4. OPTIONAL SUGGESTIONS
*   **Optional:** Enhance the "Great Hunger" caloric deficit mentioned in the RAG. The mention of "stunted, yellowed squash" is good, but a brief mention of David’s "heavy-lidded" night watches would reinforce the physical cost discussed in Chapter 11.
*   **Optional:** Sarah mentions "fire-ants are mapping the North trail." Since fire-ants are a major obstacle in Florida, a small beat of her actually stepping over or avoiding a mound would heighten the "Domestic Siege" physicality.

### 5. FORBIDDEN CHANGES / NON-GOALS
*   **DO NOT** smooth out Sarah’s "Status Code" dialogue (e.g., "Error 404"). This is her internal defense mechanism against trauma.
*   **DO NOT** remove Marcus’s rhythmic thigh-tapping. This is his "Voice Signature" grounded habit and must remain as a pacing tool for the tension.
*   **DO NOT** change David’s dropping of 'g' endings. This is a specific "Voice Signature" imperfection.

### 6. VERDICT: REVISE
The chapter is structurally sound with a clear obstacle (the Raven drone) and outcome (Leo's discovery of "Ghost Variable" status). However, the **Continuity** error regarding the "Air-Gap vs. Beacon" logic and the **Clarity** of the "Human Standard" rhythm vs. Leo's humming are structural weight-bearers that need to be reinforced before this moves to Line Editing.
