# What the golden files were generated from
|
|
|
|
|
|
|
|
|
|
The oracles import the Python these tools were ported from. The golden files
|
|
|
|
|
in this directory are the answers that Python gave, at one commit:

Regenerating against a different commit will move the goldens. That is the
|
|
|
|
|
point — the diff is the review. Record the new commit here in the same change.

The oracles find the source through two environment variables, because where
|
|
|
|
|
a checkout lives is a fact about one machine and must not be compiled in:
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
CATENA_PARITY_PYTHON=/path/to/venv/bin/python
|
2026-09-19 12:29:54 -04:00
|
|
|
CATENA_PARITY_PYTHONPATH=/path/to/book-pipeline/src:/path/to/podcast-pipeline/src:/path/to/knowledge-mcp/src
|
2026-09-19 11:54:36 -04:00
|
|
|
CATENA_PARITY_NODE=node # only if it is not already on PATH
|
2026-09-19 11:36:31 -04:00
|
|
|
```

One oracle is JavaScript rather than Python, because the code it compares
|
|
|
|
|
against is. Its three functions are copied into `oracle/cuenorm.mjs` verbatim,
|
|
|
|
|
since the module they live in opens a database connection when it loads.
