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.

 # Path to Fun — the north-star roadmap
 
-> **[ACTIVE JUNE 13–30 → the slice]** Path A's spine is built — a 2026-06-13 code audit found **13/14 systems shipped** (MC-0/1/4 · EB-1/2 · END-1). The operator answered the [Decision Gate](#the-decision-gate-mandatory-stop-after-end2) **early, as *ship the minimum***: the immediate target is the **[[End_Of_Month_Game_Jam_Slice]]** ("Awakening Engine Last Stand"), a compact single-arena base-defense demo due June 30. The one un-built spine mechanic — **END-2** (final siege + latching win, spec'd [below](#end-2--the-charge-means-something-the-cap-arms-a-final-siege-win-or-lose)) — is the slice's critical path. This doc stays the **north-star for the full game**; the slice scopes Path A to a deliverable. Milestone breakdown: [[Backlog#NEXT — Awakening Engine Last Stand (End-of-Month Slice) ★]] · adoption: [[DR-035_End_Of_Month_Slice_Adoption]]. *(Path B is untouched and provisional; the formal ship-vs-continue note is logged after June 30.)*

 > The plan to turn an engineering-complete foundation into a game that's fun to play. Direction locked in [[DR-028_Combat_Primary_Verb_Depth_First]]. This is the **forward** plan; [[Milestones]] stays the historical record, [[Backlog]] the loose pool. Living doc: the [Path A contract table](#path-a--the-proven-path-to-a-point-committed) is the only committed scope; everything in [Path B](#path-b--the-forever-track-provisional-not-scheduled) is provisional and re-derived after Path A's fun-gates pass.

 *Estimates are solo + Claude **coding-time only**. They are wider than the prior draft because several of these milestones are secretly 2–3 slices each (see the [secretly-multi note](#secretly-multi-milestones-why-the-estimates-widened)). **Fun-tuning is the unestimated, unbounded cost** — every milestone's real schedule risk is the playtest→tune→replaytest loop, not the code (see [Risk register](#risk-register) R1/R11). That is why every feel-critical value is a live server singleton, not a baked const (see [Tuning-knob surface](#tuning-knob-surface)), and why the [calendar conversion](#calendar-time-the-play-budget-assumption) below turns these into months.*

 - **Claude:** the component, the 3 server systems, the HUD bar, the lose-resolution wiring (rollback or soft-drain per the fork), EditMode coverage (Core drains under siege, regens in Calm, lose-edge fires once). **Operator:** the fun-gate playtest (is defending the Core engaging?), the diegetic Core/Engine placement, the lose-severity decision.
 - **Dependencies:** EB-1 (the structure loss-state is the natural sibling; both make the siege threatening). **Kill-risk:** if defending the Core isn't fun, nothing downstream matters — a losable base only amplifies an already-good fight; shipping it before the fight earns it actively hurts.

 **Goal:** at `GoalProgress.Charge>=Target` the Engine begins opening the Wellspring — a final, larger escalating siege — and surviving it fires the WIN beat. The meter is no longer a number that stops at 10. **This is the minimum "the game has a point."**
 - **Scope:** a server-only `GoalReachedSystem` that, on the `Charge>=Target` edge (currently UNHANDLED — `CyclePhaseSystem` increments past it forever with no clamp), arms a FINAL siege via the existing `ThreatState.PendingSiegeSize` entry point (bigger size + a distinct telegraph) and sets a replicated `RunPhase{byte=FinalDefense}`. The WIN-edge — surviving the final siege during `RunPhase.FinalDefense` sets `RunOutcome{byte=Victory}`, fires the ending event (subtitle/banner first), and for the minimum simply flips into "keep playing, the base is yours" (the endless/NG+ curve is END-5, Path B). A single client-only WIN/LOSS banner in `HudSystem` (observe `RunOutcome`; reused by END-1's overrun banner). **Zero net-new writing** for the minimum (placeholder banner text), **zero new ghosts.**
 - **Build notes:** arm the final siege through the EXISTING single entry point — do NOT add a parallel siege path (`CyclePhaseSystem` stays the sole `WaveState` writer, DR-017's atomic Calm→Siege seed). `RunPhase`/`RunOutcome` are BYTES, single-writer, server-decided. The banner is client-only observe-only. Guard the `GoalReached` edge so it arms EXACTLY ONCE (a `RunPhase!=Normal` guard) — and **clamp the currently-uncapped `Charge`.** If cadence moves to Aether-deposited (the fork below), keep it a server-only single writer (avoid co-op double-count).
