FEATURE: Inline HTML Rendering

Rendering Contract

• Text escapes HTML-significant characters.
• Emphasis and strong emphasis render as <em> and <strong>.
• Code spans render as escaped <code> content.
• Links render escaped href and optional title attributes.
• Images render escaped src, plain-text alt, and optional title.
• Hard breaks render as <br />; soft breaks preserve permitted line-break semantics.
• Autolinks and raw HTML preserve the required HTML representation.
• Entity references render as their corresponding characters, with HTML escaping where required.

Programmatic Acceptance

=== AC render-inline-suite ===
Intent: Inline HTML rendering passes the complete owned conformance scope.
Suite: scoped
Requires: executable=python3; scope=test

import subprocess import sys

result = subprocess.run( [sys.executable, "spec_tests.py", "--spec", "spec.txt", "--program", "./commonmark", "--pattern", "^(Characters and lines|Backslash escapes|Entity and numeric character references|Code spans|Emphasis and strong emphasis|Links|Images|Autolinks|Raw HTML|Hard line breaks|Soft line breaks|Textual content)$"], capture_output=True, text=True, ) print(result.stdout) print(result.stderr, file=sys.stderr) assert result.returncode == 0 === END AC render-inline-suite ===

=== AC render-inline-escaping ===
Intent: Inline rendering escapes text and code while preserving links, images, and raw HTML.
Suite: scoped
Requires: executable=python3; scope=test

import subprocess import sys

result = subprocess.run( [sys.executable, "spec_tests.py", "--spec", "spec.txt", "--program", "./commonmark", "--pattern", "^(Code spans|Links|Images|Autolinks|Raw HTML|Hard line breaks|Soft line breaks)$"], capture_output=True, text=True, ) assert result.returncode == 0 === END AC render-inline-escaping ===

User Acceptance

• None.

Guardrails

• Renderer output is derived from parsed inline nodes and never from test-result text.
• User text cannot inject markup except through valid raw HTML constructs.
