## `ctx.toolResultPrune` — `ToolResultPruneService`
Deterministic head/middle/tail pruning for current tool-result surface nodes.
```ts cordis-catalog
/**
* Measure text content in Unicode code points; non-text blocks cost zero.
* @param blocks - tool-result content to measure.
* @returns total Unicode code points across text blocks.
*/
measureContent(blocks: readonly ContentBlock[]): number
/**
* Replace an over-budget text middle while retaining rich-block order.
* Text slicing is by Unicode code point, not UTF-16 code unit, so a retained
* boundary cannot split a surrogate pair. Grapheme clusters may still split.
* @param blocks - original tool-result content.
* @returns pruned content, or `null` when the text is within budget.
*/
pruneContent(blocks: readonly ContentBlock[]): ContentBlock[] | null
/**
* Prune every over-budget tool result from one stable current-surface snapshot.
* Each replacement preserves the complete event data except for `content`,
* and points at the shadowed node for durable provenance and replay.
* @param session - session whose current surface is rewritten.
* @returns landed replacements and aggregate Unicode-code-point savings.
* @throws when the session rejects a replacement; replacements committed
* earlier in the pass remain durable.

## `ctx.tools` — `ToolRegistry`
Tool registry and execution pipeline. Scoped registrations shadow globals; one visibility resolver feeds presentation, lookup, and dispatch.
