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).

 **The Arcane Compact becomes a direct pressure; Phelan's ability can no longer stay quiet.**
 
 A pre-Compact ruin (the Athel Repository) on Duchess Pamira's territory near Thorngate — surveyed 20 years ago by a Pathfinder team that included Devod, then deferred when the sealed perimeter gate proved unbreakable. A guild scout deployed to re-assess the site was killed by that same gate ward. Ledger assigns Phelan because the wards require someone who can read pre-Compact architecture, because Devod's name is in the original survey, and because the job gets him out of Drenwick while the Compact grievance on the Book 2 crystal break is pending.
 
-**The core inversion:** Phelan opens a sealed chamber, sees an amplification weapon inside, and realises it must be re-sealed. He cannot repair the original architecture — he has to build a new seal from scratch. A perfect lock. Something his own Flaw Sight cannot crack. The man who finds every flaw must create something without any. Leon becomes the testing framework — he attacks with brute force, Phelan sees the leaks and rebuilds. Their complementary approaches become a design process.

-**At the midpoint, Cass is burned by his own institution.** The Compact severs the evidence chain from Kae. Cass goes cold, strips his resources, and vanishes. He comes to the ruin because the weapon is the last card that still has value. Two books of buildup converge in an earned confrontation.
+**At the midpoint, Cass is burned by his own institution.** The Compact severs the evidence chain from Kae. Cass goes cold, strips his resources, and vanishes — off-page for the rest of Book 3. His personal confrontation with Phelan is Book 4.
+
+**The book closes on the night before the storm.** The lock is built, tested, and holds. Artifacts packed. House funded. Cass's trail cold. Compact enforcement force 36 hours out. Devod uses Pamira's name for the first time. The reader leaves Book 3 with a complete craft-and-character victory and a clear cliffhanger.
 
 **Subplots:**

-- **Compact institutional threat.** Weakened but reorganising. Archive knowledge in guild hands undermines their authority. They come for Phelan more directly.
+**The storm arrives.** Book 4 opens with the ambush on the artifact transport, carries through the breach of the ruin, the three-party standoff at Pamira's gate, and the face-to-face confrontation with Cass that two books have been building toward. Phelan wins with restraint — his fire is sharper than it was, but the victory is that he can form the echo-spike and chooses to put it down.
+
+**The book's load-bearing resolution is the elevation.** Ledger arrives with two unnamed guild seniors. Private Flaw Sight reveal: *"I filed what you told me. I kept what I saw for myself."* Formal lift to **Senior Specialist.** The grievance dies procedurally — the reinstated inquiry cannot be heard against Phelan's new tier. **Cass's speech** — *"better packaging, same leash"* — is the knife edge of it. Phelan accepts the institutional armor knowing Cass might be right, because Mere was in the wrong room when the Compact came knocking.
+
+**The book closes at Chandler's Row.** Four days on the road home. Kimbra at the door. Carter at supper. Ledger's formal dismissal of the grievance on the kitchen table, with a handwritten note: *"The file stays open, Varrant. Yours and mine now, not theirs. Welcome to the room."* Phelan's first Senior Specialist folder open in front of him, Mere's name on a page he didn't expect. **Closing line:** *I turned the page.*
+
+**Why the split from Book 3:** The original 24-chapter Book 3 was too packed to give the character arcs and institutional confrontation the room they needed. Splitting at the end of the ruin-extraction lets Book 3 be a complete craft-and-character arc (the lock) and Book 4 be a complete confrontation-and-institutional arc (the storm).
