Covel v0.0.24

[0.0.24] - 2026-08-01

Added

• Four RPG gameplay plugins: dice-check, core-quest, affinity, inventory. The bundled set covered knowledge (codex), relationships (npc-graph), and guidance (guide), but nothing made an RPG play like one: success was narrative fiat, goals lived nowhere, items evaporated, and feelings were prose-only. dice-check is a zero-LLM pair — a pre-turn roller injects a pre-rolled d20 pool + check rules into the narrative engines, and an event recorder persists the receipts the narration sends back (🎲 message block + right-panel log). The receipt event is batched by contract (check.resolved carries a checks[] array): emit-event dedupes by topic per turn, so per-check emissions would silently drop everything after the first. The other three are post-turn extraction agents on the codex template (dual-engine narrative inject + own-state inject, needs: narrative-engine), each with a name-first batch tool, world-importable dataSchemas, a right panel, and a per-turn message block. Inventory additionally ships a player-side item-op RPC — equip / unequip / drop buttons on the panel; using an item deliberately stays in the story loop, where its consequences belong.
• Emberback (鳌背孤城·烬海纪), a third flagship world built for the RPG suite. The last great turtle carries the last city across an ember sea — and halts, without warning, above an uncharted sunken spire. Five 0-5 check attributes feed dice modifiers; worldData seeds 3 quests, 6 items (scale-coin currency included), and 3 NPC affinity records, all schema-validated against the plugins and name-aligned with the lore; plus a portrait-backed 3-NPC main cast, 6 living-world rules, and 2 world memory blocks (descent_log, turtle_state).
• LLM concurrency gate. A post-turn stage that fans out seven agents used to fire seven simultaneous LLM calls; slower providers congested until every call timed out. A process-wide FIFO semaphore (COVEL_LLM_MAX_CONCURRENT, default 4, 0 disables) caps in-flight calls, and queue waits extend deadlines end-to-end — through the retry loop and the agent tool loop — so waiting for a slot is the framework's cost, not the runtime's budget. Observed live: a tracker that burned its whole 2-minute budget queueing now completes in seconds.
• Scoped runtime retry replays the original turn's context. A bare manual trigger resolves input.inject / needs empty, so retrying a failed post-turn agent used to burn tokens extracting from nothing. retry_runtime + retryFromTurnId (and the plugin-rpc equivalent) now seed the execution with the source turn's persisted runtime outputs. Seeds are context, not products: dropped before the event fan-out (they would replay the source turn's scene.set / receipts / generation requests) and never re-persisted. The execution strip's failed-chip ↻ button uses this path and keeps the turn's narrative intact.

Fixed

• Returned agent failures now always emit runtime.failed. Four failure paths (deadline without output, requireToolUse unmet, tool-failed, schema short-circuits) returned a failed result without any terminal event — the DB recorded the failure while the execution strip spun forever. Emission now lives in the single funnel every returned failure routes through.
• Chat auto-scroll can no longer shove the page off-screen. scrollIntoView on the bottom sentinel scrolls every scrollable ancestor, including the document; any transient page overflow while a session loaded left the whole app shell scrolled out of the viewport with no way back. All follow paths now scroll the tracked chat viewport directly.

Removed

• player-identity is archived (plugins/_archive/, not loaded). Voice/persona moved to the character card long ago — set at creation via world characterAttributes, injected as {{ player.character }} — leaving the plugin UI-less, preset-less, and resolving an always-empty persona. The persona-provider capability hook and shared types stay for third-party providers.
