Docs: END-2 session log + DR-036; Backlog/Path_to_Fun/Milestones; CLAUDE.md END-2 line

Path A spine COMPLETE (14/14): Backlog SL-3 blocker cleared + marked done; Path_to_Fun END-2 done + banner; Milestones END-2 row. CLAUDE.md gains the END-2 gotcha line (replicate the outcome, don't client-derive; SiegeTimeout off during the final), net-zero via EB-1/EB-2/END-1/M7/inventory/build-grid condensations (40,445 then 40,510 w/ history note, under the 40,960 limit). DR-036 + session log capture the design, the operator forks (halt+banner, Target=4, SaveData v5), and the pre-coding + post-impl adversarial reviews.

-**The ONE blocker is END-2 (final siege + terminal win) — SL-3 below.** Today `GoalProgress.Charge` increments past `Target` forever with no clamp/consequence; there is a clear *loss* (Core overrun) but **no terminal *win***.

+**END-2 (SL-3) is CODE-COMPLETE + validated (2026-06-13) — the Path-A blocker is CLEARED.** The goal meter now arms a visibly-larger final siege at `Charge>=Target` (=4) and latches a terminal **Victory** (survive it) / **Loss** (Core breached during it), with a HUD banner + run-halt. 342/342 EditMode green; Play-validated server==client + no ordering cycle; pre-coding + post-impl adversarial reviews.

 **Critical path:** SL-1 → SL-2 → **SL-3 (END-2)** → SL-5 → SL-6 → SL-7; SL-4 (visual) runs parallel, done by Jun 23. Every milestone ends with a **falsifiable play/fun-gate**, not a test count.

 - **Fun-gate:** a fresh non-designer plays 5 min uncoached and reads mining as purposeful, building as a "prep" beat, waves as recognizable pressure, a siege death as "try again"; competent player finishes a run in 5–8 min.
