 * Normalize tool call ID for cross-provider compatibility.

 * Anthropic APIs require IDs matching ^[a-zA-Z0-9_-]+$ (max 64 chars).
 *
 * For aborted/errored turns, this function:
 * - Preserves tool call structure (unlike converting to text summaries)
 * - Injects synthetic "aborted" tool results
 * - Adds a <turn-aborted> guidance marker for the model

/**
 * Detect directly adjacent private thinking blocks inside one assistant message's
 * content. `thinking` and `redacted_thinking` are one adjacency class: the
 * Anthropic wire contract rejects a replayed assistant turn where two such blocks
 * sit next to each other with no intervening `tool_use`/`text` block (#4416).
 *
 * This is a pure, allocation-free predicate used by defense-in-depth diagnostics
 * (issue #4443): the write-time transcript assertion (coding-agent persistence)
 * and the stream-assembler SSE diagnostic (anthropic stream completion). It never
 * inspects block payloads — only the block-type sequence — so it cannot leak
 * thinking text, signatures, or credentials.
 *
 * Blocks separated by any non-private block (`tool_use`, `text`, …) are ordinary
 * interleaved-thinking shape and return `false`.
