Shared Django runtime foundations for Baltimore civic applications

baltimore-patapsco (Python)

Reusable Django runtime primitives for Baltimore civic applications.

Use build_logging_config() for the shared JSON/pretty log shape. Modules are incrementally adoptable; installing the package does not enable auth, email, or Sentry by itself.

Sentry privacy defaults

Install the observability extra and call the shared initializer only when a DSN is configured:

from baltimore.patapsco.observability import configure_sentry

configure_sentry(
    environment="production",
    release="my-app@1.2.3",
    traces_sample_rate=0.1,
)

configure_sentry() is deny-by-default: it disables automatic PII, request-body capture, and stack-frame local variables. Its event pipeline also removes request cookies and query strings, strips query/fragment data from request URLs, and recursively redacts Sentry's credential/session denylist plus common civic contact and precise-location fields. Safe operational fields such as request IDs, routes, and HTTP methods remain available.

Redaction is key-based. Applications must not attach sensitive values under misleading keys or place resident data in exception messages. Product-specific fields still require a privacy review before being added to Sentry context.
