### 1. PROSE EVIDENCE
*   **Early:** "Deep within the Siphon Hub, Lena Duval did not breathe so much as she cycled."
    *   This effectively establishes the post-human biological shift of the protagonist, moving her from a sentient being to a mechanical/biological component of the swamp.
*   **Mid:** "The trauma was a heavy stone at the bottom of a clear pool. It didn't muddy the water anymore, but she could still see its shape."
    *   This provides a strong visual metaphor for her resolved character arc, acknowledging the pain of her mother's death without it driving her current actions.
*   **Mid:** "Her fingers found only smooth, glowing skin. The locket was gone, absorbed during the apotheosis, yet her fingers kept repeating the motion—twisting air where the metal chain used to be."
    *   This brilliantly utilizes the "Imperfection signature" from the character sheet (the silver locket habit) to show what remains of her humanity even after her physical transformation.
*   **Late:** "The world is so loud, cher. So very loud. But here, we just... hum."
    *   The repetition of "so loud" and the use of "cher" anchors the ethereal sci-fi/fantasy elements back into the specific Cajun-influenced voice defined in the character profile.

### 2. CHARACTER VOICE AUDIT

**LENA DUVAL**
*   **Dialogue Quote:** "The cypress don’t lie, cher—the roots whisper what your heart’s too stubborn to hear."
*   **Signature Vocabulary/Tics:** **YES**. She uses "cher" and the "cypress don't lie" phrase noted in her voice signature example line.
*   **Avoid Forbidden Speech:** **YES**. She does not say "I give up" or offer preemptive apologies.
*   **Emotional Register:** **YES**. She displays "transcendent serenity" and "individual ego dissolved," consistent with her Ch-18 state.

**JAX HARLAN**
*   **Dialogue Quote:** "They think there’s a resource here they can harvest."
*   **Signature Vocabulary/Tics:** **YES**. While his profile is less "voice" heavy than Lena's, his dialogue reflects his "inhuman focus" and "apex protector" role.
*   **Avoid Forbidden Speech:** **YES**.
*   **Emotional Register:** **YES**. He demonstrates the "somber acceptance" and "predatory reflexes" indicated in his Ch-18 physical/emotional state.

**REMY LEBLANC**
*   **Dialogue Quote:** "You’re thinking about the 'normal' life again, aren't you, Lena? The city. The lights. The way the coffee didn't taste like silt and ritual."
*   **Signature Vocabulary/Tics:** **YES**. He acts as the "informant" and "bridge" between human past and post-human reality.
*   **Avoid Forbidden Speech:** **YES**.
*   **Emotional Register:** **YES**. He exhibits the "intellectual satisfaction" of the "memory-keeper."

### 3. STRENGTHS TO PRESERVE
*   **Transformation Imagery:** The description of Lena as "translucent, pearlescent sheen" with "bioluminescent sap... tracing the map of her veins like neon cartography" is essential to conveying her 100% arc completion.
*   **The Siphon Hub Mechanics:** The depiction of Maribelle as a "masterpiece of biological utility" (a lung/kidney) perfectly resolves her arc as a permanent part of the swamp's filtration system.
*   **Sensory Grounding:** The retention of the "smell of stagnant water" and "silt" maintains the "magnolia and mud" atmosphere required by the character notes.

---

### 4. MUST-FIX -- CONTINUITY
*   **NONE.** The chapter perfectly aligns with the [character-state] and [world-state] requirements for Chapter 18. All arcs (Lena, Jax, Maribelle, Remy) are presented as "Permanent: YES" and "100%," transitioning into their final forms as described in the RAG context.

---

### 5. MUST-FIX -- CLARITY
*   **NONE.** The transition between Lena's internal state and her psychic communication with Jax is handled smoothly through the "spiritual tether" concept.

---

### 6. OPTIONAL SUGGESTIONS
*   **Suggestion (Character Detail):** In the passage: *"Gator’s truth, she thought, the stillness was the only honest thing left."*
    *   **Reason:** The character sheet lists "gator's truth" as a verbal tic used when *stating* an undeniable fact. While using it in thought is acceptable, having her whisper it or pulse it through the spores would align more closely with her "clipping and rhythmic" chant pattern.
*   **Suggestion (Atmosphere):** Near the end, when Lena feels the intruder: *"Far off, at the edge of the five-mile dead zone, she felt a footstep."*
    *   **Reason:** Adding a mention of the "Sovereign Veil's" sentient fog reacting specifically to this footstep would reinforce the permanent world-state event established in the RAG context.

---

### 7. FORBIDDEN CHANGES / NON-GOALS
*   **Verbal Tics:** Do NOT remove "cher," "gator's truth," or "by the bayou's bones." These are essential voice signatures.
*   **Repeated Phrases:** Lena's repetition of "gone, gone" (the imperfection signature for panic) must be preserved as it shows her remaining "stubborn independence" fighting the "Great Hum."
*   **Sentence Structure:** The "clipped and rhythmic" chanting sentences must be maintained; do not smooth them into standard prose.

### 8. VERDICT
**PASSED**
**SCORE: 98/100**
**Justification:** The chapter is a masterful execution of the Final State/Chapter 18 requirements, adhering strictly to the character voice signatures (specifically Lena's locket habit and Cajun phrasing) and the physiological descriptions provided in the RAG context. All open loops are correctly reflected as resolved or perpetually ongoing (Jax's vigil). No "Must-Fix" items were identified.
