"""Human-friendly generic gateway status phrases.
These helpers deliberately avoid relaying raw model scratch text. They turn
Hermes' long-running gateway status surface into short status lines suitable
for chat surfaces.
Built-in defaults live in ``gateway/assets/status_phrases.yaml``. Users can add
portable, profile-relative phrase catalogs under ``HERMES_HOME`` either by using
conventional paths::
~/.hermes/status_phrases.yaml
~/.hermes/status_phrases/*.yaml
or by pointing config at a relative file/directory::
display:
status_phrases:
path: status_phrases/whatsapp.yaml # relative to HERMES_HOME
mode: append # append (default) or replace
Absolute paths and ``..`` escapes are ignored on purpose so config stays
profile-portable and does not accidentally read arbitrary files.
Only configured phrase strings are used; raw tool args, commands, previews, and
reasoning text are never interpolated into the returned phrase.
