Phase 12: Seasons + Weather (rolls, rain, storm, wet/cold)

48-day year (4 seasons × 12 days), daily weather rolls, rain visual,
storm flash, Wet/Cold statuses with mood thoughts.

Three-agent fan-out — Opus prepped contracts up front (event_bus
signals, Clock season constants, Weather autoload stub) so the three
slices could run fully parallel and integrate on first try.

Calendar (Agent A):
- Clock season API — SEASON_SPRING/SUMMER/AUTUMN/WINTER constants,
  current_season(), current_season_index(), day_of_season(),
  current_year(), DAYS_PER_SEASON=12, DAYS_PER_YEAR=48
- EventBus.season_changed emitted on transition (mirrors phase_changed)
- Top-bar SeasonLabel ('Spring 1/12') with localized season names via
  Strings.t() — season.spring/summer/autumn/winter + season.format
- Terrain TileMapLayer seasonal palette modulate
  (spring=warm-green, summer=neutral, autumn=warm-orange, winter=cool-blue)

Weather (Agent B):
- autoload/weather.gd — daily roll triggered by Clock day-index change
  Probability tables per season (placeholders, tune Phase 20):
    spring  60% clear / 35% rain /  5% storm
    summer  75% clear / 18% rain /  7% storm
    autumn  50% clear / 35% rain / 12% storm /  3% cold_snap
    winter  55% clear / 15% rain / 10% storm / 20% cold_snap
- EventBus.weather_changed signal
- scenes/world/rain_overlay.tscn — procedural _draw() diagonal raindrops
  on a CanvasLayer (chosen over CPUParticles2D for pixel-art exactness
  and to colocate storm-flash logic in one weather-aware script)
- Storm flash — Tween-driven ColorRect at random 4-8s intervals
- Save round-trip preserves _last_day_index to prevent double-rolling

Wet + Cold + Mood (Agent C):
- StatusCatalog.wet(severity 1-2) — Damp at 25, Soaked at 60 (of 100)
- StatusCatalog.cold(severity 1-3) — Mild at 25, Severe at 60, Extreme at 85
- ThoughtCatalog.damp(-3), soaked(-6), cold_thought(-4)
- Pawn._wet_accum / _cold_accum floats, ticked in _process_statuses:
  +0.02/tick rain (×2 storm), -0.05/tick decay when sheltered
  +0.015/tick cold winter-or-snap (×2 cold_snap)
- _sync_wet_status / _sync_cold_status — severity-flip detection with
  one Audit line per transition
- _is_sheltered() v1: World.floor_layer.get_cell_source_id != -1
  Phase 13 replaces with proper Room BFS
- _wet_accum / _cold_accum round-trip through Pawn.to_dict / from_dict
- Persistent thought sync in _process_thoughts after in_darkness

MCP runtime verified:
- Top-bar 'Spring 1/12' renders; green seasonal terrain tint visible
- Rain droplets render across screen; storm flash captured mid-animation
- Bram wet=26 (Damp) → wet=65 (Soaked) with mood thought (-6), mood=30
- Cora cold=30 cold_snap → Cold status sev=1 + Cold thought (-4), mood=32
- Daily weather rolls visible day 0-5 (rain → clear → rain → clear → rain)

Quick-edit fixup mid-flight: Variant inference errors on
'var old_sev := s.severity' (untyped Array loop var). Same trap as
the Phase 7 crop fix; pattern is now to always explicit-type ':='
when the rhs is non-typed-Array element access.

Delegation: 3× gdscript-refactor agents in parallel, 1× quick-edit
for the Variant-inference fix; integration + MCP verify on Opus.

 - **Phase 10 deliberately partial** — wolf-side combat (two-roll, bleed on hit) shipped, but pawn-side weapons/armor/cover/friendly-fire deferred. Acceptance demo's full chain (wolf → bites → pawn bleeds → doctor saves) awaits player weapons. WolfSpawner pack size 1–2 vs design target 1–4 — tune up post Phase 20 numbers pass.
 - **Bleed-out timer shipped at demo value** `BLEED_OUT_TICKS = 1200` (~ minutes) instead of design value `432000` (6 in-game hours). Documented in `status_catalog.gd`; flip on first time-balance pass. Recorded so it doesn't ship to a release at the demo value.
 - **Bed-claim bug noticed in passing** during ULTRA-speed run: `Bram bed claim failed at /root/Main/World/Bed — sleeping on floor` for two of three pawns even when beds free. Doesn't gate Phase 12; logged for separate triage.
-- Next: Phase 12 (Seasons + Weather) or Phase 13 (Rooms + Roofing + Beauty + Cleaning) — user's call.
+- **Phase 12 (Seasons + Weather) shipped same day.** Three-agent fan-out (Agent A = clock seasons + season top-bar + terrain palette; Agent B = Weather autoload + procedural rain overlay + storm flash; Agent C = Wet/Cold statuses + mood thoughts + shelter check). Opus prepped contracts up front (event_bus signals, Clock season constants, Weather autoload stub) so all three could run fully parallel.
+- **Pre-fan-out contract pattern was the key.** By writing the public API surface to disk *before* dispatching agents, each agent's slice compiled standalone and integrated on first try. Worth repeating for any future "multi-system phase" — pay the 5-minute scaffolding cost, save the round-trip merge fixup.
+- One quick-edit fixup needed: Variant inference errors on `var old_sev := s.severity` (untyped Array loop var). Same trap as the Phase 7 crop fix. Pattern: always explicit-type any `:=` declaration assigned from a non-typed-Array element.
+- **MCP runtime verified all paths.** Top-bar shows "Spring 1/12", rain droplets render across screen, storm white-flash caught mid-animation, wet status flipped 0→Damp(26)→Soaked(65) with mood thought sync, cold status fired on cold_snap with -4 mood. `_is_sheltered()` proxy (has floor) works for v1; Phase 13 Room BFS replaces it.
+- Next: Phase 13 (Rooms, roofing, beauty, dirtiness, cleaning) is the natural follow-up — it pays the `_is_sheltered()` debt and unlocks beauty/dirty mood thoughts.
