### 1. STRENGTHS TO PRESERVE
*   **The "Four-Beat Ping":** The chapter correctly maintains Marcus’s physical habit ("his fingers moving in a rhythmic four-beat sequence"). This is a vital carry-over from the [voice-sig-marcus] profile.
*   **Cardinal Navigation:** Consistent with his [voice-sig-arthur] legacy and current [voice-sig-david] profile, characters navigate by "North Bank," "South-by-Southeast," and "East-by-Northeast" rather than left/right.
*   **Sarah’s Reframing:** The transition of Sarah from a victim to a "primary arbiter of a local network" (lines 14-15) aligns perfectly with her Ch-21 Character State ("Sarah has successfully replaced corporate logistics with a localized 'Seed of Barter' economy").
*   **Technical Metaphor as Voice:** Marcus’s dialogue continues to use the "unoptimized" and "diagnostic" vocabulary established in his voice signature (e.g., "The math doesn't work," "Resource depletion at four percent").

**Voice Differentiation Check:**
*   **Marcus:** YES. His reliance on Boolean logic ("True/False") and diagnostic reports identifies him immediately.
*   **Sarah:** YES. The blend of Texas colloquialisms ("comin' in," "handin'") with support-desk jargon ("triage," "status code") is unique to her.
*   **David:** YES. His rhythmic, tectonic speech and focus on the land distinguish him from the "tech-refugees."
*   **Helen:** YES. Her "Long Wait" philosophy and heavy, deliberate sentence structure ("Is your shadow heavy enough yet?") are distinct.

### 2. MUST-FIX — CONTINUITY
*   **CONTRADICTION: Sarah’s Living Status.** 
    *   **The Error:** Chapter 21 presents Sarah as physically present in Cypress Bend, interacting with Marcus, Helen, and neighbors (Line 11: "Marcus... was looking at the way Sarah’s hands moved"). 
    *   **The Establishment:** The [voice-sig-sarah] (Sarah Jenkins) identifies her role as "Emotional Catalyst (Deceased-equivalent/Displaced)" and notes Marcus "can still hear [her pen] in the silence of Cypress Bend." More critically, the Character State for Ch-21 lists her location as "The Kitchen Hub/Porch, Cypress Bend," but her Arc says she "successfully replaced corporate logistics with a localized 'Seed of Barter' economy." 
    *   **The Resolution:** While the Character State for Ch-21 suggests she is present, the Voice Signature/Lore implies she is a "ghost in the machine." **However**, looking at the Ch-21 Character State, she is listed as "Permanent: YES" with a location in the Bend. The contradiction exists within the RAG: The Voice Signature says "Deceased-equivalent/Displaced," but the World State says she is the "Sovereign" of the kitchen. 
    *   **Action:** Confirm Sarah is physically present in the Bend as a survivor. The Voice Signature "Deceased-equivalent" must be interpreted as "dead to her old life," not literally dead. **BUT**, there is a internal logic error: Sarah's [voice-sig] says "My son is eating cereal... because of a code you signed off on." In Ch-21, Leo is physically there in the trees.
    *   **CRITICAL FIX:** Ensure the text acknowledges that Leo is safely with her in the Bend, as established in the Ch-21 Character State, rather than being a distant motivation as suggested in the older Voice Signature.

*   **CONTRADICTION: The Medical Stent.**
    *   **The Error:** Line 53 claims the stent is for "Helen. Her tremors had been spiking." 
    *   **The Establishment:** Character State ch-21 for Helen Vance lists her physical condition as "Frail but steady; hands busy with herbal preservation." 
    *   **The Correction:** Reconcile Helen's "steady" hands in the state log with the "spiking tremors" in the text. Either Helen is hiding the tremors from the general state log, or the text is introducing a new physical degradation not yet indexed.

---

### 3. MUST-FIX — CLARITY
*   **Passage:** "The Great Dark thickened" (Line 48).
    *   **Issue:** The World State ch-21 explicitly says "The Great Dark: ENDED -- Replaced by 'The Sovereign Mesh'." 
    *   **The Fix:** Clarify if "The Great Dark" refers to the atmospheric/environmental lingering effects, or if the author meant "The Sovereign Mesh." Using "Great Dark" implies the crisis is active, whereas the state log says it has transitioned.

---

### 4. OPTIONAL SUGGESTIONS
*   **Arthur’s Legacy (Optional):** Mentioning that Arthur's hoarded mechanical parts served as the primary currency for this barter (as per [World State: ch-21]) would strengthen the connection to the established lore regarding his "Legacy" and "Cardinal logic."
*   **The Alpha-7 Logs (Optional):** The [voice-sig-marcus] notes he is carrying the Alpha-7 back-end log. A brief mention of the physical drive or the weight of that unencrypted data would ground his "God-tier" hangover.

---

### 5. FORBIDDEN CHANGES / NON-GOALS
*   **Do NOT remove the "G-dropping":** (e.g., "haulin’," "learnin’"). This is a specific regression/imperfection signature for David and Helen Vance.
*   **Do NOT smooth Marcus’s dialogue:** His third-person diagnostic speech ("Diagnostic: Resource depletion") is a core character trait.
*   **Do NOT remove technical metaphors:** Using "latency," "throughput," and "firmware" to describe corn and milk is the intended voice for this project ("Cypress Bend").

### 6. VERDICT
**REVISE.** 
Major continuity clash regarding Sarah’s status (Deceased-equivalent/Displaced vs. Physical Arbitrator) and Helen's physical condition (Steady vs. Spiking Tremors) must be reconciled to maintain a clean project index. Additionally, the state of "The Great Dark" contradicts the "Ended" status in the world log.
