Module metadata 

Bounded, redacted JSON metadata helpers for ingest pipelines. Bounded and redacted JSON metadata helpers for untrusted ingest input.

Constants

MAX_METADATA_JSON_BYTES

Maximum encoded metadata size before the payload is replaced by a truncation marker.

MAX_METADATA_KEY_CHARS

Maximum number of Unicode scalar values retained from a metadata key.

MAX_METADATA_OBJECT_FIELDS

Maximum number of elements retained from a metadata object or array.

MAX_METADATA_STRING_CHARS

Maximum number of Unicode scalar values retained from a metadata string.

Functions

attrs_to_metadata_object

Build a sanitized JSON object from key/value attributes while enforcing field limits.

bounded_metadata_json

Sanitize and encode metadata, replacing oversized results with a valid JSON truncation marker.

try_bounded_metadata_json

Like bounded_metadata_json, but refuses to truncate: returns None when the sanitized encoding exceeds MAX_METADATA_JSON_BYTES, so callers whose metadata carries load-bearing keys (e.g. the extracted agent_docker identity) can back out instead of losing them.
