/**
 * saga.detach — remove a Saga member by clearing its `parentId` containment edge.
 *
 * Idempotent: re-running against a member that is no longer parented to the Saga succeeds
 * with `removed: false`. Every invocation (whether or not it removed a row)
 * appends a single JSON line to `.cleo/audit/saga-detach.jsonl` so the
 * repair history is auditable — mirroring the append-only pattern used by
 * `appendContractViolation` in `audit.ts`.
 *
 * Primary use case: repair ADR-073 §1.2 invariant I7 violations (a saga
 * accidentally linked as a member of another saga — historical
 * T9831-nested-in-T9799 scenario). Dogfooded in the T10118 ship PR.
 *
 * @task T10118
 * @saga T10113 — SG-SAGA-FIRST-CLASS
 * @epic T10209 — E-SAGA-ENFORCEMENT
 * @see ADR-073-above-epic-naming.md §1.2

/**
 * Clear the `parentId` edge between a Saga and a member Epic.

 * Used to repair an ADR-073 §1.2 invariant I7 violation (a nested-saga

 * @param projectRoot - Absolute path to the project root.
 * @param params - sagaId + memberId of the containment edge to remove.
 * @returns EngineResult with `{ sagaId, memberId, removed, reason, timestamp }`.
 *
 * @example
 * ```typescript
 * const result = await detachSagaMember('/repo', {
 *   sagaId: 'T9799',
 *   memberId: 'T9831',
 *   reason: 'ADR-073 I7 violation repair',
 * });
 * // result.data.removed === true on first call, false on subsequent calls.
