 ## Open Questions
 
+### Threads to close in Ch20–21–Epilogue
+
+*Inventory assembled 2026-04-12. Each item has a planned landing spot. Revisit this list before drafting Ch20/Ch21/Epilogue and check off as resolved.*
+
+- **Thresholds / Charlette shop deed.** Shelved since Ch11 ultimatum reveal (Mere reclassified both parents). Outline slots this as Ch21 "Devod's moment." Pair with the Devod post-drain recalibration beat so one scene carries both.
+- **Devod post-drain demeanour change + Pathfinder reframe.** Ch15 Brennan Toor reveal (Vethek Pass) demolished Phelan's civilian model of Devod. Devod woke with "real focus." Ch21 landing: Phelan visibly recalibrates his relationship with Devod — no speech, just a shift in how he treats him. Pair with Thresholds.
+- **Mere's "Dad" reclassification follow-through.** Ch11 "Come by tomorrow, Dad." The word was said once; Ch21 should show it lived-in, not repeated. Quiet beat.
+- **Kae's ongoing care logistics.** Mere's ghostveil moss supply flagged Ch19. Devod likely co-managing care off-page. One confirming Ch21 beat that the 80% herbal protocol is sustainable — reader needs to know Kae isn't a time bomb.
+- **House plans Revision 11.** Devod's integrated-drainage kernel filed against Rev 10 (east-facing kitchen). Retainer increase from Tier Two should compress the build timeline. Ch21 new-status-quo beat.
+- **Financial state reset.** Ch21 "earned quiet" beat with updated Tier Two math: 22 silvers/month retainer + 12 silvers/month ore + Book 1 leftover. Matches the Book 1 close-on-money pattern.
+- **Leon's on-page philosophy-shift landing.** Ch20 handles Leon only via Phelan's internal reflection. Ch21 training-scene beat gives him one pointed question about a buyer he wouldn't have asked pre-Brida's. Small. No speech. Mirrors Phelan's own reluctant growth.
+- **Carter's Book 2 landing beat.** Supply-chain B-plot is mechanically closed (Ch06 Hendrick Voss, Ch12 studded jacket delivery) but Carter as a character hasn't had a Book 2 landing scene. Ch21 workshop/domestic beat or brief reference.
+- **Fire training ceiling acknowledgment.** 15s plateau hit (Ch12 → Ch15). Ch21 training scene should acknowledge the plateau *as* the plateau — no breakthrough, no forced progress. Primes Book 3.
+
+### Updates to existing open questions
+
+- **Victim targeting logic — why these specific people? [RESOLVED 2026-04-12.]** The Vellen Thrace question is answered: Vellen is the illegitimate second son of Duchess Isolde Merrenwood of Wenlow (new worldbuilding canon). Cass targeted him because he recognised the Merrenwood paternity trail in Compact records and decided to take the housekeeping shot AND bank the leverage simultaneously — one action, two benefits. This lands in **Ch20 Phase 3** as a Ledger/Phelan reveal and becomes Book 2's closing beat. The "early housekeeping → random when Kae went rogue" theory is not the answer for Vellen specifically; Vellen was a surgical leverage play. Other early victims may still fit the housekeeping framing, but only Vellen's targeting is now on-page. See `chapters/book2/ch20-input.md` Phase 3 and `characters/duchess-merrenwood.md` Hidden Son section.
+- **Ch20 Phase 3 micro-hook ending. [RESOLVED 2026-04-12.]** Replaced with a substantive ~900–1,200 word reveal beat ("The Name in the Ledger") in which Ledger discloses Vellen's paternity to Phelan as a **Tier Two structural disclosure**. The chapter closes on Phelan walking home carrying the knowledge — "one more thing I didn't ask for" — and the final image is the kid who may or may not have been looking for his mother. Fully specified in `chapters/book2/ch20-input.md` Phase 3. Book 3+ runway tracked in `outline/book3-outline.md` — referenced in Ch21 as part of Ledger's elevation-scene "folders you can see now you couldn't before" beat, parked for Book 4+.
 - **Leon's grey-market contact names:** Which contacts does Carter keep? — pure drafting detail, resolve during chapter writing.
-- **Victim targeting logic — why these specific people?** Kae attacked Vellen Thrace *in his room* — that's a targeted hit requiring knowledge of where the victim lives. If early drainings were Cass-directed (before Kae spiralled beyond control), what connects the victims? Possible subplot: a hidden thread connecting the victims that reveals the drainings started as deliberate Compact housekeeping before Kae's addiction made the targeting erratic. The transition from targeted to random IS the moment Kae went rogue — and that's when the Compact stopped investigating. Consider developing during Ch20 debrief if it adds weight without derailing the case-closure pacing.
-- **Ch20 Phase 3 micro-hook ending:** Needs Book 3 arc context. Direction: something from Ledger on the way out that reminds the reader this file has a destination. Light touch, not cliffhanger. See `outline/book2-outline.md`.

+- **Tomael (Carter's brother).** Seeded Ch02, paid off Ch12. The studded jacket *is* the payoff: Carter gave Phelan the jacket to protect him because of what happened to Tomael. Thread is mechanically closed. No Ch21 beat required. Listed here only to prevent future sessions re-flagging it as dangling.
