Replaces LICENSE (GPLv3 -> AGPLv3) and prepends `SPDX-License-Identifier: AGPL-3.0-or-later` to every source file across decnet/, decnet_web/, tests/, scripts/, and tools/. Rationale: closes the GPLv3 ASP loophole so any party operating a modified DECNET as a network service must offer their modified source. Personal copyright (Samuel Paschuan) + inbound=outbound contributions make a future unilateral relicense infeasible. - LICENSE: full AGPL-3.0 text (gnu.org/licenses/agpl-3.0.txt) - COPYRIGHT: project copyright notice - tools/add_spdx_headers.py: idempotent header injector (shebang- and PEP 263-aware) Touches 1565 source files (.py, .ts, .tsx, .js, .jsx, .css, .sh). No behavior change; comments only.

"""Coverage for :mod:`decnet.realism.diurnal`.
|
|
|
|
Two functions to exercise:
|
|
|
|
* :func:`in_work_hours` — straightforward window membership including
|
|
the wrap-around (``22:00-06:00``) case and the fail-open behaviour
|
|
on malformed windows.
|
|
* :func:`sample_mtime` — must (a) return a ``datetime`` strictly in
|
|
the past, (b) clip to the configured backdate cap, and (c) snap the
|
|
hour-of-day into the persona's window when the unconstrained
|
|
candidate would land outside.
