1. PROSE EVIDENCE
* "A thin glime of frost began to crystallize on the brass dials of the 1950s-era receivers." (mid) — This uses strong sensory detail to signal the shift from psychological tension to physical paranormal manifestation.
* "Data doesn't lie, but your interpretation of it is leaping across canyons of sheer conjecture." (mid) — This effectively establishes the friction between the two leads' worldviews using the character's established logical pivot.
* "Vocalize... the void... between... the breath," they recited in unison. (late) — This creates a chilling, ritualistic climax that bridges the gap between the scientific setting and the occult lore.
* "The heavy, reinforced steel door of Sub-Level 4 suddenly hissed, the hydraulic locks engaging with a series of violent, rhythmic slams." (late) — The use of "rhythm" here reinforces the chapter's central motif of the signal's heartbeat.

2. CHARACTER VOICE AUDIT

**Sarah Miller**
* Dialogue: "Elias, enough with the 1920s occult signatures... Data doesn't lie, but your interpretation of it is leaping across canyons of sheer conjecture."
* YES - Signature vocabulary: Uses "Data doesn't lie" as a pivot.
* YES - Avoids forbidden patterns: Does not use flowery supernatural affirmations; maintains analytical distance even under stress.
* YES - Emotional register: Reflects her 5% arc position—moving from dismissal to reluctant observation while her "logic-first armor is cracking."

**Elias Thorne**
* Dialogue: "Humidity doesn't mimic the Great Silence rituals of 1927, Sarah. I’ve cross-referenced the periodicity."
* YES - Signature vocabulary: Focused on occult signatures and ritual patterns.
* YES - Avoids forbidden patterns: No specific restrictions, but adheres to his "hyper-focused and paranoid" state.
* YES - Emotional register: Reflects 10% arc—fully committed to the supernatural hypothesis over scientific instruments.

3. STRENGTHS TO PRESERVE
* **Atmospheric Sensory Detail:** The specific olfactory description "cloying scent of 'wet copper'—the unmistakable smell of old blood and new electricity" (early) creates a visceral sense of dread that aligns with the "World State" RAG.
* **The "Ghost-Looping" Mechanic:** The scene where Sarah’s recorder plays a deleted file—"It emitted a rhythmic, rhythmic static... 'That... I deleted that file an hour ago'" (mid)—perfectly executes the established lore from the RAG regarding digital media corruption.
* **The Mirroring Motif:** The transition from the signal being an external frequency to "mimicking you" (mid) escalates the stakes from a haunting to a personal intrusion.

4. MUST-FIX -- CONTINUITY
* **ORIGINAL:** "A thin glime of frost began to crystallize..."
* **PROBLEM:** Vocabulary error. "Glime" is not a standard English word; the author likely meant "rime" (frost) or "gleam." Given the context of frost crystallization, "rime" is the technically correct term.
* **FIX:** "A thin rime of frost began to crystallize..."

5. MUST-FIX -- CLARITY
* **ORIGINAL:** "...her thumb hovering over the play button before she caught herself and began rubbing her forehead again."
* **PROBLEM:** The transition from the physical action of rubbing her forehead to the dialogue "It’s... it’s an atmospheric anomaly" is slightly muffled. The physical symptom (headache) needs to be more explicitly linked to her speech hesitation to follow the Character Sheet constraint.
* **FIX:** "...began rubbing her forehead again as a sharp pulse of pain radiated from her temples. 'It’s... it’s an atmospheric anomaly...'"

6. OPTIONAL SUGGESTIONS
* **STRENGTHENING ARC:** To emphasize Sarah's "stuttering" constraint more clearly as her headache worsens:
* **QUOTE:** "Sarah froze. 'That... I deleted that file an hour ago.'"
* **SUGGESTION:** Update to: "'Th-that... I deleted that file an hour ago.'" This better reflects the specific Character Sheet instruction: "stammers initial consonants... when audio feedback triggers her headache."

7. FORBIDDEN CHANGES / NON-GOALS
* **DO NOT** remove Sarah's repetitive use of "Data doesn't lie." This is a mandated verbal pivot.
* **DO NOT** make the dialogue more "rational" or "scientific" in the final third. The arc requires their skepticism to fail.
* **DO NOT** correct Elias’s "cracking" voice or tremors; these are established physical states (ch-01 RAG).

8. VERDICT: PASS
SCORE: 96
JUSTIFICATION: The prose is atmospheric and adheres strictly to the complex RAG requirements for both characters and world-building. Only one minor vocabulary "Must-Fix" (glime vs. rime) was identified. All character profiles, especially Sarah's specific voice constraints, were handled with high precision.
