/**
 * Audit lineage reconstruction — SDK primitive.
 *
 * Promotes git-log + release-tag lineage reconstruction to a first-class
 * SDK verb. Git IS the immutable hash-chained ledger; this module mines it
 * to produce a structured {@link ReconstructResult} consumed by T1216 audit tasks.
 *
 * No `.jsonl` sidecar is emitted — git's DAG is the source of truth (per
 * FP peer note, T1322 council verdict 2026-04-24).
 *
 * Security: all git subprocess calls use `execFileSync` with strict `argv`
 * arrays — no shell interpolation or user-controlled string concatenation
 * in the command string.

/**
 * Reconstruct the git-backed lineage for a task and its inferred children.
 *
 * This is the first-class SDK verb for audit lineage reconstruction (T1322).
 * It queries git directly and returns a fully-typed {@link ReconstructResult}
 * that T1216 audit tasks consume for their 4-outcome verdict.
 *
 * **Algorithm**:
 * 1. Find direct commits whose message references `taskId`.
 * 2. Infer child ID range from commit-message mining and numeric adjacency.
 * 3. Find child commits for each inferred child ID.
 * 4. Collect all release tags containing any direct or child commit.
 * 5. Compute first/last timestamps across the full commit set.
 *
 * @param taskId - The task ID to reconstruct (e.g. `"T991"`).
 * @param repoRoot - Absolute path to the git repository. Defaults to `process.cwd()`.
 * @returns A fully-typed {@link ReconstructResult} with all git-derived lineage data.
 *
 * @example
 * ```ts
 * import { reconstructLineage } from '@cleocode/core/audit/reconstruct.js';
 *
 * const result = await reconstructLineage('T991');
 * console.log(result.releaseTags.map(t => t.tag));
 * // → ['v2026.4.98', 'v2026.4.99', ...]
 * ```
 *
 * @task T1322
 * @epic T1216
