### 1. PROSE EVIDENCE
*   **Quote 1 (Early):** "The air in Sub-Level 4 thicked, turning viscous and heavy, as if the oxygen had been replaced by a dense, metallic vapor."
    *   *Commentary:* This effectively transitions the "Whisper" from a mere sound to a physical, environmental threat, reinforcing the "Wet Iron" world state.
*   **Quote 2 (Mid):** "The strobing emergency lights of the Archive, now slaved to the signal’s oscillation, flickered in a neurological cadence—black, white, black, gray—until the world looked like a corrupted film strip from a century ago."
    *   *Commentary:* This passage successfully integrates the [World State] requirement regarding emergency lighting while providing a strong visual metaphor for the 1927 "Great Silence" theme.
*   **Quote 3 (Late):** "She looked down at her recorder’s small LCD screen. The waveform wasn't a jagged line of noise. It was a perfect, repeating geometric flower, a mandala of interference that shouldn't be possible in a digital environment."
    *   *Commentary:* This provides necessary visual evidence of the "ghost-looping" anomaly mentioned in the Sarah Miller character state.
*   **Quote 4 (Late):** "The racking began to groan, the heavy steel twisting under the invisible torque of the frequency."
    *   *Commentary:* This reinforces "The Respiration" world event by showing the physical pressure waves affecting inanimate objects, heightening the stakes.

### 2. CHARACTER VOICE AUDIT

**Character: Sarah Miller**
*   **Line:** "E-Elias, get back from the console... Empirically speaking, this is... this is acute acoustic trauma."
*   **YES** - Signature vocabulary/tics: Uses "Empirically speaking" and exhibits the "Th-this" stammering imperfection signature tied to her audio-feedback trigger.
*   **YES** - Avoids forbidden patterns: She avoids flowery supernatural affirmations, sticking to "acute acoustic trauma" even when faced with the impossible.
*   **YES** - Emotional register consistency: Her "analytical paralysis" (from her Arc/Physical state) is perfectly captured as she tries to calculate decibels while her head is "splitting."

**Character: Elias Thorne**
*   **Line:** "It’s not damage, Sarah. It’s calibration... The signal was taking a breath."
*   **YES** - Signature vocabulary/tics: His dialogue reflects his abandonment of logic for "ritualistic communion."
*   **YES** - Avoids forbidden patterns: He stays within his "transfixed and obsessive" emotional state.
*   **YES** - Emotional register consistency: He is at 20% arc progress, where logic is "abandoned in favor of ritual," visible in his refusal to wipe away his own blood.

### 3. STRENGTHS TO PRESERVE
*   **The 14Hz Convergence:** The rhythmic pacing of the prose mirrors the 14Hz pulse described in the context ("...words falling onto the beats of the signal").
*   **Sensory Consistency:** The "wet iron" scent (ch-02 unresolved loop) is used both as a recurring atmospheric detail and a plot point ("It’s our own chemistry reacting to the resonance").
*   **Sarah’s Recorder:** Keeping the digital recorder as an "empirical anchor" that ultimately betrays her provides a great focal point for her arc transition.

### 4. MUST-FIX -- CONTINUITY
*   **ORIGINAL:** "The recording a spike of forty decibels in the sub-sonic range alone."
*   **PROBLEM:** Minor grammatical error (The recording a spike) and a slight mismatch with the "The Respiration" world event which describes a "shout." 40dB is actually very quiet (like a library).
*   **FIX:** "I'm detecting a spike of a hundred and forty decibels in the sub-sonic range alone." (140dB is the threshold for pain/shouting).

---

### 5. MUST-FIX -- CLARITY
*   **ORIGINAL:** "Th-th-thistle. The consonants caught in her throat as she tried to force her brain back into its analytical grooves."
*   **PROBLEM:** "Thistle" feels like a random word choice that distracts from the tension. The voice signature says she stammers "initial consonants," but usually on the word she is trying to speak.
*   **FIX:** "Th-th-this... The consonants caught in her throat as she tried to force her brain back into its analytical grooves."

---

### 6. OPTIONAL SUGGESTIONS
*   **Suggestion:** Reference the "The Curator" more specifically to ground the isolation.
*   **Quote:** "The Archive Administration had likely locked the systems from above..."
*   **Improvement:** "The Curator had likely initiated the lockdown from the surface, dismissive as ever, burying the 'technical failure' along with them." This reinforces the [Faction Attitude: Hostile/Negligent] from the World State.

---

### 7. FORBIDDEN CHANGES / NON-GOALS
*   **Do NOT "fix" Sarah's repetitive dialogue** on the tape loop (*"—from a rational standpoint—"*). This is a character signature and a manifestation of the "ghost-looping" open loop.
*   **Do NOT remove Elias's nosebleed or trembling.** These are established [Character State: ch-02] physicalities that must remain.
*   **Do NOT soften the "wet iron" scent.** It is a core unresolved loop for Elias.

### 8. VERDICT

**SCORE: 92/100**
**REVISE**

**Justification:** The chapter is an excellent atmospheric piece that perfectly adheres to the voice signatures and world state. However, it requires a small revision for the technical "Must-Fix" regarding the decibel level (a continuity error regarding the "shout" intensity) and the "Thistle" word choice which stutters the prose's momentum unnecessarily. Once these minor technical edits are made, it is a high-quality "Pass."
