InteractionScreen — CanvasLayer overlay (Layer=50, WhenPaused) that
pauses the tree on open and runs a Core DialogueRunner against
playScreen-owned aggregates (Reputation, Flags, ContentResolver,
QuestEngine). Codex-themed centered panel ~760 px with header
(NPC name, role line "Innkeeper of Millhaven" via
LastIndexOf('.')-split TitleCase, bias profile · disposition tag
from EffectiveDisposition.Breakdown, optional Scent Literacy line
for scent_broker / scent_literacy / master_nose feature holders),
history scrollback (last C.DIALOGUE_HISTORY_LINES, per-speaker
text colour for NPC / PC / Narration), numbered option list
(skill checks prefixed [SKILL DC N]), footer hint. Input: 1-9
top-row + numpad, Enter to dismiss when over, Esc / F to leave.
Godot's Key enum is long-backed for unicode + modifier bits, so
the arithmetic cast through int is explicit.
Effect routing on each ChooseOption: drains
runner.Context.StartQuestRequests into _playScreen.QuestEngine.Start
with a freshly-rebound QuestContext (PlayerCharacter pinned each
call) — quest journal UI is M8 but the engine fires immediately.
runner.Context.ShopRequested raises a "Shop ships with M8" toast
via PlayScreen.Toast and clears the flag so re-entry doesn't loop.
Stub NPCs (no dialogue_id, missing tree, or null content) get the
"(They have nothing to say yet.)" panel + Goodbye button — same
fallback the MonoGame source ships.
PlayScreen interact tick. Tactical-mode _Process now polls
EncounterTrigger.FindInteractCandidate(_actors) and caches the
result in _interactCandidate (cleared at world-map zoom). HUD
appends "[F] Talk to {DisplayName}" when non-null. Edge-detected
F press → AddChild(new InteractionScreen(npc, this)), candidate
cleared immediately so a held F can't stack overlays. M8 will
wire real LOS into the FindInteractCandidate losBlocked callback;
M7.5 ships with the default AlwaysClear.
Added internal accessors PlayScreen now surfaces so the overlay
doesn't poke private state: Reputation, Flags, QuestEngine, World,
WorldSeed, ClockSeconds, PlayerPosition, Content,
BuildQuestContextForDialogue(), Toast(text). All scoped internal —
not part of any public API.
