[BUG] [v0.0.7] clean_html() parses DOM and iterates all descendants in a no-op loop with unused _result before calling remove_tags() (html.rs:506-517)

Project

cortex

Description

When clean_html removes images under certain settings, it parses the DOM and walks all descendants in a loop that performs no meaningful mutation, allocates an unused string, and then relies on remove_tags for the real work. This is wasted CPU and complexity on hot paths (scraping), and suggests an incomplete refactor. While not always user-visible, it is a maintainability and performance smell.

Steps to Reproduce

1. Open the affected cortex command or screen.
2. Execute the exact input pattern named in this issue title and narrative.
3. Compare actual output against the expected contract documented by the reporter.

Expected Behavior

The reporter expects cortex to match documented CLI/TUI contracts for this flow—correct output, honest flags/help, and no silent contradictions—consistent with the problem statement at the top of this rewrite.

Actual Behavior

When clean_html removes images under certain settings, it parses the DOM and walks all descendants in a loop that performs no meaningful mutation, allocates an unused string, and then relies on remove_tags for the real work. This is wasted CPU and complexity on hot paths (scraping), and suggests an incomplete refactor. While not always user-visible, it is a maintainability and performance smell.

❌ Validation Summary — Issue #53515

Code verification failed: The code indeed contains the useless loop and unused _result allocation in clean_html as described. However, this is a code smell and performance issue, not a user-facing bug. The screenshot cannot show a real user experience of this bug, making it invalid for this bounty program.

Confidence Score: 4/5

• This issue does not meet the minimum requirements for a valid bounty submission.
