description: "Packages one already-produced recompute_fund_nav receipt and one already-produced test_nav_error_materiality receipt into a CSSF Circular 24/856-shaped NAV-error disclosure bundle: what happened, when it was detected, the materiality threshold applied, the affected period, and the correction. The materiality verdict and error/policy figures are echoed verbatim from the cited materiality receipt's own output, never recomputed here. HARD FENCE: this pack cites the referenced receipts by execution_hash and tool_id; it performs zero NAV recomputation and zero materiality-threshold arithmetic of its own, and it makes no claim of CSSF Circular 24/856 compliance, informative citation only. The affected_period, correction and notification fields are caller-supplied and asserted (zero-egress, no CSSF submission of any kind). Fourth entry of the NAV / Fund-Administration Computation Lineage family, alongside recompute_fund_nav, test_nav_error_materiality and compute_fund_expense_ratios."
