	The Claude cache % read 100% whenever anything was cached, because the metric's denominator (inputTokens) excluded cached tokens on Anthropic. Fixed upstream in ../claude/provider-anthropic (inputTokens = total prompt); this commit adds the companion retention metric and exposes it: - transport-contract: WarmResponse += expectedCacheRate - transport-http: POST /chat/warm returns expectedCacheRate = cacheRead/(cacheRead+cacheWrite) - cache-warming: computeExpectedCacheRate + a per-conversation 'cache retention' surface stat - handoff: documents the fix + cache-rate vs expected-cache (cross-turn) for the FE Live-verified vs claude haiku: real turn cache rate 61% (was inflated 100%); warm within TTL expectedCacheRate=100%, after expiry=0%.

	cache-warming controls Extend the surface framework so cache-warming exposes per-conversation controls: - ui-contract: add NumberField (settable free-value numeric) to SurfaceField; add optional conversationId to subscribe/unsubscribe/invoke + surface/update - surface-registry: SurfaceContext { conversationId? } on getSpec/invoke (backward-compatible) - transport-ws: thread conversationId; key subscriptions by (surfaceId, conversationId); tag surface/update replies with conversationId - cache-warming: per-conversation surface — Toggle(enabled) + Number(interval seconds, cache-warming/set-interval) + Stat(last cache %); drop the currentConversationId closure Global surfaces (surface-loaded-extensions) unchanged. 784 vitest + 109 bun = 893 tests; tsc -b EXIT 0; biome clean.
2026-06-11	feat(cache-warming): per-conversation prompt-cache warming + warm() service	Adam Malczewski
	Backend-driven warming targeting whatever provider a conversation uses (incl. the external Claude provider-anthropic). Core engine + on/off + last-cache-% done; interval-as-view-control pending a ui-contract NumberField (surface-system gap). Mechanism: - kernel: expose HostAPI.emit (typed bus event emit; counterpart of on) - session-orchestrator: turnStarted/turnSettled event hooks (conversationId/cwd/model); warm() service (cacheWarmHandle) reusing the real-turn assembly (byte-identical prefix, provider-agnostic), refuses mid-turn, never persists/emits, returns Usage - cache-warming (new ext): per-conversation timers (arm on settle, cancel on start, in-flight invalidation), calls warm(), pct=round(clamp(cacheRead/input,0,1)*100), persists {enabled,intervalMs} (default on/240s), registers a controls surface - host-bin: register cache-warming; transport-http: HostAPI stub +emit (fan-out) Honors old-code invariants. 760 vitest + 109 bun = 869 tests; tsc -b EXIT 0; biome clean.
