### 1. PROSE EVIDENCE
*   "The air in Sub-Level 4 thicked, turning viscous and heavy, as if the oxygen had been replaced by a dense, metallic vapor." (Early)
    *   This effectively establishes the physical manifestation of the signal, grounding the "Whisper" in sensory horror.
*   "Th-th-thistle. The consonants caught in her throat as she tried to force her brain back into its analytical grooves." (Mid)
    *   This masterfully demonstrates the character’s internal struggle by showing her brain grasping for a random logical anchor (a word like 'thistle') to combat linguistic degradation.
*   "They hovered, caught in the invisible pressure waves of the 14Hz shout, orbiting Elias like tiny, dying stars." (Late)
    *   This visual provides a stark, haunting image that signals the shift from mere acoustic interference to localized physical law-breaking.
*   "The red light was flickering. No, not flickering—it was pulsing." (Mid)
    *   This simple distinction between random failure and rhythmic intent heightens the uncanny nature of the signal’s sentience.

### 2. CHARACTER VOICE AUDIT
**Elias Thorne**
*   **Quote:** "It’s not damage, Sarah. It’s calibration. The resonance... it’s matching the Great Silence signatures."
*   **Signature Vocabulary/Tics:** YES. Uses "calibration" and references the "Great Silence," aligning with his archive-focused obsession.
*   **Avoids Forbidden Patterns:** YES. No restrictions were placed on Elias's speech other than abandoning logic.
*   **Emotional Register:** YES. He sounds transfixed and ritualistic, matching his Arc at 20%.

**Sarah Miller**
*   **Quote:** "E-Elias, get back from the console... Empirically speaking, this is... this is acute acoustic trauma." 
*   **Signature Vocabulary/Tics:** YES. Uses "Empirically speaking" and "acute acoustic trauma."
*   **Avoids Forbidden Patterns:** YES. She does not use flowery supernatural affirmations; even when terrified, she attempts to categorize the phenomenon as "acute acoustic trauma."
*   **Emotional Register:** YES. Her "analytical paralysis" is evident as she tries to calculate decibels while her ears bleed.
*   **Imperfection Signature:** YES. The stuttered "E-Elias" and "th-th-the" match her profile's trigger (audio feedback causing stammers).

### 3. STRENGTHS TO PRESERVE
*   **The 14Hz Rhythmic Integration:** The prose mirrors the character's internal state through rhythm. Specifically, "Elias’s voice was rhythmic, his words falling onto the beats of the signal," reinforces the "Biometric Mirroring" effect established in the World State.
*   **The Sensory Anchor of "Wet Iron":** The repetition of the metallic scent ("The scent was overwhelming now. Wet iron. The smell of a butcher’s shop floor...") maintains continuity with the unresolved open loop from ch-02.
*   **Sarah’s Rationalization:** Sarah's refusal to accept the supernatural even as her recorder loops her own voice ("Data doesn't lie, Elias. We are experiencing a high-energy EM event...") is a crucial character beat for her fatal flaw of rigid skepticism.

### 4. MUST-FIX -- CONTINUITY
*   **ORIGINAL:** "...the Archive Administration had likely locked the systems from above..." 
*   **PROBLEM:** Minor perspective shift. Sarah and Elias can speculate on why the systems are locked, but stating the Archive Administration's internal reasoning ("assuming a technical failure") leans into omniscient narration in a scene focused on their immediate sensory isolation.
*   **FIX:** "The Archive equipment no longer responded; the administration had likely initiated a remote lockout, burying Sub-Level 4 in the dark to contain what they didn't understand."

### 5. MUST-FIX -- CLARITY
*   **ORIGINAL:** "The 1927 atmospheric anomalies were—hnn—they were solar-flares or ionospheric shifts."
*   **PROBLEM:** The sound "hnn" is ambiguous. It could be a grunt of pain or a sound of effort, which breaks the precision of Sarah's analytical voice.
*   **FIX:** "The 1927 atmospheric anomalies were—[she sucked in a breath through gritted teeth]—they were solar-flares or ionospheric shifts."

### 6. OPTIONAL SUGGESTIONS
*   **Optional (Sarah's recorder):** "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..." 
*   **Improves:** Relates the visual of the "geometric flower" to the "1927 occult patterns" mentioned earlier. Labeling it specifically as a "Cymatic pattern" would strengthen Sarah’s analytical lens.

### 7. FORBIDDEN CHANGES / NON-GOALS
*   **Do NOT remove Sarah’s stutters:** These are not typos; they are the "Imperfection signature" defined in her character sheet and occur during audio-feedback triggers.
*   **Do NOT remove the "Wet Iron" repetition:** This is a specific open loop from the RAG context that must remain unresolved until the biological transformation is complete.
*   **Do NOT "fix" Elias's repetitive dialogue:** His mirroring of the signal’s cadence is an intentional part of his ritualistic arc (Arc 20%).

### 8. VERDICT
**SCORE: 96**
**JUSTIFICATION:** The chapter demonstrates an exceptional adherence to the provided character sheets, specifically Sarah's complex "analytical vs. terror" voice. All active world events (14Hz convergence, The Respiration) are seamlessly integrated into the prose without "info-dumping," and the prose itself is of a high technical standard. The minor continuity and clarity fixes do not impact the core narrative.

**FINAL VERDICT: PASS**
