matrx-content-guard
Deterministic HTML/CSS/JS content validation + patch/diff editing for the
Matrx CMS agent-authoring layer. Pure Python, no DB access, no tool-framework
imports — every agent mutation to html_pages / client_* content flows
through this library before it's written.
See CONTRACT.md for the full typed API and FEATURE.md for the durable
design notes (parser choice, permissive-first policy rationale, byte-
preservation guarantee).
from matrx_content_guard import validate_content, apply_patch, SearchReplacePatch, SearchReplaceHunk
report = validate_content("<script>alert(1)</script>", "html_page_document")
report.blocked # False — inline script is a supported feature; only genuinely dangerous constructs block.
result = apply_patch(
"<h1>Hello</h1>",
SearchReplacePatch(hunks=[SearchReplaceHunk(search="Hello", replace="Hi")]),
)
result.result # "<h1>Hi</h1>"
