     **Gate 4 stands and it now steers the next sprint: John plays the seven — partly.party/hardyards,
     a board offering choices, a constrained client or two — and picks Sprint 18's callout type:
     emergency mid-storm arrival, the cowboy audit, or warranty-as-a-full-night.**
+[I] 2026-07-21 — **SPRINT 17 (THE BOOK OF CLIENTS, PART 1) INTEGRATION COMPLETE (main).** D's
+    second pass merged fast-forward; selftest **515/0/0** on the final tree (510 part-1 + D's
+    5 pins, the exact sum), verified in the browser. Deploy NOT yet run: the session's
+    permission gate blocked tools/deploy_hardyards.sh (ssh + docker to the games VPS) —
+    John runs it, or green-lights it, and the one-sprint gap rule stays honest.
+    The week is seven nights offered two at a time: THE BOARD every morning, client terms
+    with teeth (the cap refuses in the client's own voice), the charter line on every SCORE
+    IT card, the heal's second wire, the honesty gate over NIGHTS ∪ POOL, and THE POOL YARD
+    — the first yard a player can only reach by choosing it — carrying E's corroded post as
+    exactly the trap-with-a-tell the repo ships.
+
+    **D's cold-play verdicts, the short form:** choosing feels like running a business (the
+    fee-vs-exposure-vs-terms arithmetic at the morning table is the strongest new feeling
+    in the game); a constraint reads as a client, not a rule. The week ran 7/7 stood up,
+    6/7 gardens, $401, ★0.0 with 5 warranty jobs — the ledger keeps every receipt.
+
+    **Filed forward (Sprint 18 seeds, all with live cases attached):** ⚖️ the sharpest —
+    **should declining a BOOKED night cost standing?** The board twice let a fee-maximizer
+    dodge the campaign's own set-pieces (the wildnight for a Tuesday southerly; the
+    designed-loss icenight against a winnable $68) — "does saying no cost you" is no longer
+    hypothetical. For B: the wildnight played-vs-gardenfly recipe disagreement (find the
+    variable; candidate is hail impact load reaching the rig only in-game), and the $5-tier
+    clean-boundary optimism (N3 broke the audit's own "clean" line at 1.17/1.2). For E/A:
+    the second-rust-post landmine (shared collateral key; the yard ships ONE and pins it).
+    For A: N7's same-client double offer reads odd under "the other goes to somebody else".
+    Gate 4 is JOHN'S: partly.party/hardyards — seven nights, the board, the Vasilaros cap,
+    and the Karalis pool yard in the pool. Your three sentences steer Sprint 18.
