split book3 into book3 + book4

Book 3 was too packed — the lock-build arc and the grievance-elevation
arc were competing for the same climactic space. Split at Ch15/Ch16:
Book 3 is now 18 chapters ending on "The Night Before" (lock built,
tested, holds; house funded; storm visible on the horizon). Book 4 is
13 chapters starting with "The Ambush" and carrying the
confrontation/standoff/elevation/aftermath arc.

Left deliberate gap chapters for future character development: 2 in
Book 3 (Ch10, Ch17), 3 in Book 4 (Ch02, Ch07, Ch10).

 ## Logline
 
-Phelan's life is settling — Mere pregnant, Kimbra re-entering his orbit, the house plans at revision 12 — when the Compact files a formal grievance reopening the Book 1 qualifications inquiry — the one Ledger got withdrawn — with the Book 2 crystal break as new evidence. Relief sought: strip his certification and expel him from the guild. Ledger ships him to a pre-Compact ruin on Duchess Pamira's territory to get him out of reach while the procedural fight runs, but the ruin is a test and a showcase: Ledger has been grooming him for elevation, and the grievance is the pressure that forces the move. Inside the ruin is a sealed weapon that magnifies any working 15-fold. Phelan opens the seal to understand it, then has to build a perfect lock against his own ability — and do it before Cass, burned by his own institution, arrives with the Compact's enforcement force at his back.

The storm itself — confrontation, breach, standoff, elevation — is Book 4.
 
-**The Compact is the real antagonist.** Cass is the face. The book's institutional confrontation and personal confrontation are the same confrontation at two scales. **Mere's pregnancy is the Act 3 stakes engine** — the Compact arc threatens her directly when enforcement officers arrive at the estate where she is staying.
+**The Compact is the real antagonist.** Cass is the face. Book 3 delivers the craft-and-character victory (the lock holds). Book 4 delivers the institutional and personal confrontations. **Mere's pregnancy is the slow-building stakes engine** — not yet in the blast radius at Book 3 close; Book 4 puts her there.

-Pure Phelan first-person, past tense, throughout. Kimbra's subplot is processed through his noise. Pamira is seen mostly through Devod's interactions. Cass's arc is off-page until Ch19. The Compact enforcement arrival is seen from Phelan's position (ruin during the breach, estate during the standoff and elevation).

 ## Open Questions
 
-- **Ch21 elevation scene:** Who else is in the room with Ledger and Phelan? Two other senior guild figures are referenced but unnamed. Resolve during drafting or defer to Book 4
-- **Compact commander:** Named or anonymous? Current plan: named but not recurring — an institutional face, not a character arc
-- **Tier system total count:** Deliberately unresolved. "Senior Specialist above Two" is all the book commits to
-- **Pamira's territory name:** **Thorngate duchy** (established). The 45-acre site within it needs a name eventually — "Kade Reach" is the survey's working name per the 2026-04-19 revision spec; whether the site itself carries that name in Book 3 prose is a drafter's call.
+- **Gap chapter commitments (Ch10 and Ch17):** drafter picks candidates from the outline's list during drafting.
+- **Tier system total count:** Deliberately unresolved. Book 4's elevation commits to "Senior Specialist above Two," no further specificity.
+- **Pamira's territory name:** **Thorngate duchy** (established). The 45-acre site within it is "Athel Repository" in the registry, "Kade Reach" in the 20-year survey paperwork — whether the site carries Athel or Kade Reach in Book 3 prose is a drafter's call.
 - **Kimbra's surname:** TBD
 - **Working title commit:** "The Sealed Chamber" vs. "What Stays Buried"
-- **Book 2 Ch20 micro-hook:** Confirm the Pamira/Thorngate inquiry reference is in place when Book 2 Ch20 finalises
