CellView gains FlashTransform: bright copper pulse + brief scale punch
(0.45s) on CargoConvertedEvent, distinct from the warmer golden
FlashProduce used by productions. EventAnimator routes transformer
conversions through the new phase so the flash reads as a conversion
moment rather than a second production tick.
PieceView picks up cargo colors for Tools (copper), Arms (deep red),
and Gold, matching the cargo-slide particle palette — pieces carrying
those transformed cargoes now render the correct indicator instead of
defaulting to white.
DemandDef gains optional ConsumptionPerTurn and SustainTurns. When
ConsumptionPerTurn > 0 the demand maintains a buffer filled by
deliveries and drained each turn. Shortage fires the first turn the
buffer can't cover consumption; it clears when the buffer refills.
SustainedTurns counts consecutive non-shortage turns, and IsSatisfied
flips to true once it meets SustainTurns — so the victory condition
becomes "no shortage for N consecutive turns" as soon as a mission opts
in. Classic demands (ConsumptionPerTurn = 0) behave exactly as before.
TurnExecutor runs the consumption sub-phase after transfers. Two new
events (DemandShortageStarted / DemandShortageCleared) let the
presentation surface the state later. BoardSnapshot + CampaignLoader
carry the new fields; no existing mission opts in yet, so
campaign_01.json is unaffected.
Renames mission 7 from "Le Couronnement" to "Le Comptoir" (it only sets
up the tools→gold chain — the coronation is now the final mission) and
adds:
- Mission 8 "L'Expansion Finale" (12×10): a Forge Est (wood→tools) and
an Armurerie Est (stone→arms) on new rightmost columns, plus walls
that force pieces to route around them. An Entrepôt Est demand on
(11,9) gives the mission its own goal without depending on the old
demands.
- Mission 9 "Le Couronnement" (12×12): the Cathédrale occupies row 11
as three adjacent demands — outils, armes, and or — so the player
must keep all three transformation chains running simultaneously to
complete the campaign.
Existing file tests updated for the new count and rename; new
Campaign01Tests asserts structure and non-regressive terrain across all
nine missions.
TrajectView now draws an arrow at each endpoint (since pieces oscillate
between start and end, both directions are relevant) and runs a looped
width/alpha tween that breathes between 0.3 and 0.75 over ~2.2s. The
pulse makes stationary relays visually distinct from static board art
without competing with active cargo/particle animations.
OnMissionAdvanced now plays a three-track cinematic when the auto-advance
fires between missions:
- Every cell in the rebuilt board pops in with a scale+fade tween
(0.45s, back ease) so terrain expansion reads as "appearing".
- The camera smooth-pans + zooms back to the new board center over
0.7s, undoing any collision zoom that was active.
- A full-size "Mission N\nName" overlay fades in, holds for ~1.4s,
then fades out and frees itself.
The per-cell animation doubles as the expansion cue; a dedicated
new-cells-only tween can be layered later if needed. No new engine
surface — hooks onto the existing MissionStartedEvent path.
DetailPanel exposes the currently-shown piece id; Main's key handler
delegates Delete or Backspace to the same path as the Retirer button
when a piece is selected. Harness gains "delete" under key() so UI
tests can exercise the shortcut directly.
EventAnimator now emits CollisionOccurred at the end of the collision
phase, carrying the struck cell and victim/destroyer identity. Main pans
and zooms the camera onto the cell over 0.45s and shows a fading toast
("Pion détruit par Tour — retourné au stock", or "collision mutuelle"
for same-status ties). The toast fades out after 3s and leaves the
camera framing the collision so the player can inspect the aftermath
before resuming.
InputMapper tracks a mouse-down over a placed piece and promotes it to
drag mode once the cursor travels past an 8px threshold. Legal drop
cells (those where the piece's start→end vector still fits a legal
placement) are highlighted in green. Releasing on a legal cell emits a
RelocateRequested signal; Main feeds it to MovePieceCommand, which is
already undoable via the existing history stack.
Escape or releasing on an invalid cell cancels. The harness gains a
relocate() helper so UI tests can script drag-and-drop moves without
synthesizing motion events.
Delete autonomous_plan.md (fully shipped), PLAN_playtest.md (all P1-P7
done), PLAN_missions.md and PLAN_leveldesign.md (partial — engine done,
UI polish + 3 final missions + recurring demands + transformer visuals
remain). The surviving TODO list lives in docs/PLAN.md.
Also add the 6-step dev loop to CLAUDE.md (take next topic → implement →
tests → UI test → docs → commit).
