P/B -0.08 is outside the believable range [0.05, 50.0]; suppressed as a likely corrupted book value. net_margin -308.46% exceeds +/-100%, which is either a genuine outsized margin (e.g. a loss exceeding revenue) or a near-zero revenue denominator; flagged for review. BSE's published net_margin (-420.37%) exceeds the +/-100% plausibility bound; the source value is retained with a machine-readable warning. Our computed operating_margin (-3.21%) diverges from BSE's own published figure (20.66%) by more than 100%. BSE's figure is a different, BSE-computed number (not necessarily TTM, standalone-only) — treat as a cross-check/fallback signal, not proof either figure is wrong.
