Audit found three things compiled in that shouldn't have been: the User-Agent
carried the author's domain, the cluster threshold and window were module
constants the pipeline never overrode, and the embedding model was pinned --
which blocked the one change most likely to be wanted, swapping in a
multilingual model for native-language sources.
Configuration is now three files with distinct roles: config.toml (machinery),
profile.toml (who the reader is), sources.toml (what to read). All are
relocatable via NEWS_CONFIG_DIR. news/*.py now contains no interest, place name,
feed URL, or personal identifier.
tests/test_config.py keeps it that way: it builds a configuration for an
invented reader and asserts none of the author's identity or preferences reaches
the running code. Writing it immediately found a real bug -- CONFIG_DIR was
resolved at import time, so NEWS_CONFIG_DIR silently did nothing if set after
the module was first imported. Now resolved per instantiation.
Documented the coupling that portability creates: [clustering].threshold and
[scoring].veto_absolute are cosine constants calibrated against one corpus with
one model, so changing [embedding].model invalidates both.
