OperationId:post_indicators_corrmatrix

NxN pairwise Pearson correlation of LOG returns of CLOSE prices over the last window common trading days (inner-joined on shared dates). Symbols are deduplicated (case-insensitive) and SORTED; since the matrix is symmetric, the response symbols and matrix keys are in sorted order (this also avoids cache fragmentation). A null matrix entry means the pair is undefined (zero-variance series). Daily only (interval=1d). Uses CLOSE prices, matching the close-based BETA / CORREL indicator family.
