Raising GLOBAL_LOG_LEVEL to WARNING buys quieter output but not less work: 241 INFO call sites interpolate their payload into an f-string before the logging call gets to drop it. The heaviest is get_doc, which logs every chunk id and metadata dict in a collection, so on the full-context retrieval path that is the entire knowledge base, once per chat request.
That one line at WARNING, CPython 3.12:
| knowledge base | payload | before | after |
| -------------- | ------- | -------- | ------- |
| top-k of 3 | 1.2 kB | 3.8 us | 0.07 us |
| 500 chunks | 201 kB | 583.6 us | 0.08 us |
| 5000 chunks | 2.0 MB | 5.8 ms | 0.15 us |
The lazy form log.info('query_doc:result %s %s', result.ids, result.metadatas) hands the payload to record.getMessage(), which the InterceptHandler only reaches once a record has passed the level check. Output at INFO is byte-identical. Two sites that already built their message eagerly, one str concat and one % operator, move to the same lazy form.
Firecrawl /search returns either `{"data": [...]}` (flat list — v1, and
what frost19k reported on #23966) or `{"data": {"web": [...]}}` (v2,
current production). The parser only handled the dict shape:
data = response.get('data') or {}
results = data.get('web') or []
On a list-shape response, `data.get('web')` raised AttributeError,
caught by the function's outer try/except, and `search_firecrawl`
silently returned []. Web search worked against v2 endpoints but is one
upstream-format-change away from failing closed again. Accept either.
