+micromate/idf_to_bw_report.py — adapter that projects a parsed Thor IDF
+report (+ binary metadata + decoded IDFH intervals) into the
+``bw_report``-shaped dict that :mod:`sfm.report_pdf.gather_report_data`
+consumes.
+
+Lets Thor events flow through the existing Series III Event Report PDF
+pipeline without duplicating the renderer.  Thor's report content is
+~95% the same data shape as BW's; the field names differ but the
+underlying metrics map 1:1.
+
+Caveats
+───────
+
+- **Mic units** — Thor records ``MicPSPL`` natively in dB(L).  This
+  adapter sets ``bw_report.mic.pspl_dbl`` directly; the report
+  renderer recomputes the equivalent psi via its dBL→psi formula.
+- **Saturation / above-range flags** — Thor doesn't always mark
+  ``OORANGE`` the way BW does; we set ``zc_freq_above_range`` only
+  when a `>100` sentinel was preserved in the raw text.
+- **Per-interval data** — for IDFH events we build ``interval_times``
+  by stepping ``IntervalSize`` from ``HistogramStartTime``; the binary
+  decoder confirms one record per step (882 / 881 / 881 ... across
+  the corpus).
+- **calibration_by parsing** — Thor's free-form ``Calibration : November
+  22, 2023 by Instantel`` is split on ``" by "`` to extract the
+  calibrator; the date prefix is parsed where possible, otherwise
+  the binary-extracted ``calibration_date`` from
+  :class:`micromate.idf_file.IdfBinaryMetadata` wins.
