+MPACT
+Copyright 2022, Robert M. Samples, Sara P. Puckett, and Marcy J. Balunas
+
+Qt-free crash/error reporting. Installs a ``sys.excepthook`` that, on any
+otherwise-unhandled exception:
+
+1. formats a full report (traceback + environment: MPACT/Python/platform
+   versions, timestamp, optional context such as the tail of the run log),
+2. writes it to a timestamped file under a crash-log directory (so there's a
+   durable record even if the user dismisses the dialog), and
+3. hands the report to a GUI callback that asks the user whether to send it.
+
+The "send" path is deliberately backend-free: it builds a pre-filled GitHub
+*new issue* URL (title + body) for the MPACT repo, so reporting is one click
+in the browser and nothing leaves the user's machine until they choose to
+submit it. That satisfies "prompt the user before sending" without any cloud
+egress, DSN, or account.
+
+Why not Sentry (the obvious off-the-shelf option): ``sentry-sdk`` is excellent
+for hosted/web services but (a) sends events to a Sentry project by default --
+exactly the silent-egress this tool should avoid for a desktop research app,
+(b) needs a DSN/account to be provisioned, and (c) still needs a custom
+``before_send`` hook + dialog to honour "ask first." For a single-user desktop
+tool the local-log + pre-filled-GitHub-issue flow gives the same practical
+benefit (a complete traceback in the maintainer's hands) with no infrastructure
+and no privacy surprise. If MPACT ever ships to many non-technical users and a
+central error feed becomes worth it, Sentry with ``before_send`` gating is the
+documented upgrade path.
+
+This module is Qt-free and unit-tested (see ``tests/test_crashreport.py``); the
+GUI dialog is injected as a plain callback.
