### 1. PROSE EVIDENCE
*   **Quote 1 (Early):** "it felt heavy, saturated with the sharp, metallic tang of ozone and a cloying scent of 'wet copper'—the unmistakable smell of old blood and new electricity."
    *   **Commentary:** This effectively anchors the sensory experience of the sub-level, bridging the gap between mechanical failure and the macabre occult history.
*   **Quote 2 (Mid):** "Data doesn't lie, but your interpretation of it is leaping across canyons of sheer conjecture." 
    *   **Commentary:** This line perfectly encapsulates the friction between the two protagonists, showing Sarah’s desperation to maintain a logical framework.
*   **Quote 3 (Late):** "A thin glime of frost began to crystallize on the brass dials of the 1950s-era receivers."
    *   **Commentary:** The use of "glime" (presumably a portmanteau or archaic variant of gleam/rime) creates a specific, eerie texture, though it may border on a typo.
*   **Quote 4 (Late):** "The rhythmic thrumming spiked into a shrill, piercing squeal that forced her to drop the device. It hit the floor, but the screen didn't go dark. It stayed lit, the play-counter spinning backward at an impossible speed."
    *   **Commentary:** This passage uses strong visual and auditory cues to escalate the supernatural threat from atmospheric to overt.

### 2. CHARACTER VOICE AUDIT

**Sarah Miller**
*   **Line:** "Elias, enough with the 1920s occult signatures... Data doesn't lie, but your interpretation of it is leaping across canyons of sheer conjecture."
*   **Signature Vocabulary/Tics:** **YES.** She uses "Data doesn't lie" as a pivot and employs "empirically speaking" (later in the scene) as required by her profile.
*   **Avoid Forbidden Speech:** **YES.** She maintains her skepticism and avoids "flowery supernatural affirmations," even when terrified.
*   **Emotional Register:** **YES.** Her transition from dismissal to "analytical freezing" (stating she needs to check logs while the room freezes) matches her 5% arc progression.

**Elias Thorne**
*   **Line:** "Humidity doesn't mimic the Great Silence rituals of 1927, Sarah. I’ve cross-referenced the periodicity. It’s isomorphic."
*   **Signature Vocabulary/Tics:** **YES.** He uses academic/occult jargon like "isomorphic" and "periodicity" which aligns with his hyper-focused state.
*   **Avoid Forbidden Speech:** **YES.** He treats the instruments as secondary to his intuition, as seen when he reaches for the vellum-bound ledger.
*   **Emotional Register:** **YES.** He is "hyper-focused and paranoid," viewing the danger as validation rather than a reason to flee.

### 3. STRENGTHS TO PRESERVE
*   **Sensory World-Building:** The specific environmental cues ("48°F", "wet copper", "ozone") from the Project Context are integrated seamlessly into the prose: "cloying scent of 'wet copper'—the unmistakable smell of old blood and new electricity." (Early).
*   **Digital Haunting Logic:** The concept of "ghost-looping" is established as a specific mechanic of the signal, which pays off when Sarah’s recorder malfunctions: "It emitted a rhythmic, rhythmic static—a low-frequency thrum that mirrored the breathing pattern..." (Mid).
*   **The Power Dynamic:** Sarah’s reluctant debt to Elias is used effectively to drive the plot forward: "You owe me this, Sarah. You said you’d support the investigation." (Late).

### 4. MUST-FIX -- CONTINUITY
*   **ORIGINAL:** "A thin glime of frost began to crystallize..." (Late).
*   **PROBLEM:** "Glime" is not a standard English word. While it sounds atmospheric, it is likely a typo for "rime" (frost) or "gleam." Given the context of frost, "rime" is the accurate meteorological term.
*   **FIX:** "A thin rime of frost began to crystallize on the brass dials..."

### 5. MUST-FIX -- CLARITY
*   **ORIGINAL:** "It emitted a rhythmic, rhythmic static—a low-frequency thrum..." (Mid).
*   **PROBLEM:** The repetition of "rhythmic, rhythmic" feels like an accidental double-word error rather than a stylistic choice for emphasis, especially since the word appears again in the very next phrase.
*   **FIX:** "It emitted a deep, rhythmic static—a low-frequency thrum..."

### 6. OPTIONAL SUGGESTIONS
*   **Clarification of the "Archive":** (Optional) The transition from the "spectral analyzer" (Late) to the "1950s-era receivers" (Late) suggests a mix of tech. A brief mention of why they are using disparate eras of equipment might deepen the "Oakhaven" lore.
*   **Stammer Implementation:** (Optional) Sarah's profile mentions she stammers initial consonants when audio feedback triggers her headache. While she does this once ("Th-this frequency"), adding it to her final line ("Th-that’s not possible") would reinforce her physical toll.

### 7. FORBIDDEN CHANGES / NON-GOALS
*   **Sarah’s Skepticism:** Do NOT make Sarah more "believing" earlier. Her rigid insistence on "atmospheric anomalies" and "archaic wiring" is a core character trait defined in the RAG.
*   **Elias’s Intensity:** Do NOT soften Elias’s dialogue. His "devotional" fervor and "bloodshot" eyes are essential to his 10% arc commitment to the supernatural hypothesis.
*   **Technical Jargon:** Terms like "isomorphic," "periodicity," and "spectral analyzer" must remain to maintain the "Academic/Researcher" voice of the project.

### 8. VERDICT
**SCORE: 92/100**
**VERDICT: REVISE**

**Justification:** The chapter is excellent and adheres strictly to voice signatures and project context. However, the use of the non-standard word "glime" and the repetitive "rhythmic, rhythmic" require minor mechanical corrections to ensure professional-grade prose.
