The folder is becoming the home of one-doc-per-subsystem pages (intro + data structures + cordis services/events), so the name must describe the whole contract, not just the type-vocabulary third of it. Mechanical rename rebuilt on current master: every inbound Markdown link, generator constant, website route, type-equiv manifest path, and spec expectation moves together; the zh sides of the notes whose prose names the folder are aligned (子系统) in the same change; touched bilingual pairs re-recorded; translation-prompt snapshot re-recorded (its example embeds development.md). Historical Agent Note slugs keep their dated filenames.

Token 计量
English | 中文
@deepseek-ai/dsh-token-meter 公开一个独立的回放快照，用于表示请求压力与按位置计算的表层定价。logRevision 表示生成该计量中每个字段时所消费的持久事件数量。
来源：packages/llm/token-meter/src/types.ts
TokenMeasurement
/** Detached immutable request-pressure and surface snapshot at one consumed log revision. */
interface TokenMeasurement {
/** Number of durable events consumed; equal to the next unread event seq. */
readonly logRevision: number
/** Provider or heuristic anchor used for this measurement. */
readonly baseline: TokenMeasurementBaseline
/** Signed repricing of current surface content relative to the baseline anchor. */
readonly surfaceDeltaTokens: number
/** Non-negative current request-and-response pressure. */
readonly totalTokens: number
/** Total heuristic tokens across the current surface. */
readonly surfaceTokens: number
/** Current surface nodes in positional head-to-tail order. */
readonly nodes: readonly TokenSurfaceNode[]
}
baseline.kind === 'usage' 表示最近一次成功的提供方调用具有相同的规范请求信封，且该调用的总量不低于其完整启发式锚点。estimated 表示不存在可复用的保守 usage 锚点，因此服务使用固定启发式规则对完整信封和表层定价。后续成功请求会替换早先的锚点；有符号的 surfaceDeltaTokens 会保留相对于匹配锚点的增长与缩减。totalTokens 仍表示请求与响应压力，surfaceTokens 则是仅针对表层的启发式总量，等于所有节点价格之和。
TokenSurfaceNode
/** One token-priced node in the current ordered session surface. */
interface TokenSurfaceNode {
/** Durable sequence number of the surface event. */
readonly seq: number
/** Heuristic tokens for the exact message projected by this node. */
readonly tokens: number
}
表层顺序具有权威性；替换节点的持久 seq 可能高于位置排在其后的节点。该快照不可变，不会随底层回放折叠推进而增长。
