OSS restructuring for open-core model: - Rename package from agentserver/ to xml_pipeline/ - Update all imports (44 Python files, 31 docs/configs) - Update pyproject.toml for OSS distribution (v0.3.0) - Move prompt_toolkit from core to optional [console] extra - Remove auth/server/lsp from core optional deps (-> Nextra) New console example in examples/console/: - Self-contained demo with handlers and config - Uses prompt_toolkit (optional, falls back to input()) - No password auth, no TUI, no LSP — just the basics - Shows how to use xml-pipeline as a library Import changes: - from agentserver.* -> from xml_pipeline.* - CLI entry points updated: xml_pipeline.cli:main Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

xsd_validation.py — Validate the extracted payload against the listener-specific XSD.
|
|
|
|
After payload_extraction_step isolates the payload_tree and provenance,
|
|
this step validates the payload against the XSD that was auto-generated
|
|
from the listener's @xmlify dataclass at registration time.
|
|
|
|
The XSD is cached and pre-loaded. The schema object is injected into
|
|
state.metadata["schema"] when the listener's pipeline is built.
|
|
|
|
Failure here means the payload violates the declared contract — we collect
|
|
detailed errors for diagnostics.

|
Part of AgentServer v2.1 message pump.
