Feat: added Deployment Summary UX for the previous PR #114

[Khanz9664]

Summary

The Deployment Summary has been successfully integrated natively into the core TrustReport user experience, drastically improving the discoverability of deployment recommendations without breaking any existing API surfaces or logic.

1. Architectural Changes

The deployment summary string (and its rich HTML equivalent) is now systematically embedded into the three primary report generation endpoints:

TrustReport.show()

The core CLI output now features the deployment summary printed immediately after the Score Summary / Penalty Explanation section and before Key Observations. This establishes a highly natural reading flow:

1. Score
2. Why the score happened (Penalties)
3. Can I deploy? (Deployment Verdict & Recommendations)
4. Detailed Observations

TrustReport._generate_text_report()

The plain-text export (used when saving to .txt files) mirrors the structure of show(), ensuring the deployment summary is persisted when sharing analysis logs in CI/CD pipelines or text archives.

TrustReport._repr_html_()

The Jupyter Notebook output now renders a visually distinct, rich HTML block. It utilizes the structured deployment_explanation dictionary rather than the plain text string, converting the reasons into a clean bulleted list with color-coded success/failure icons (✓/✗), and the recommendations into a formatted checklist.

Note

Backward Compatibility Maintained:
As intended, _format_score_explanation() was left completely intact. No existing trust score mechanics, blocking logic, or visualization endpoints were altered. This is a 100% additive UX enhancement.

2. Test Coverage

The test suite in tests/test_deployment_explanation.py was expanded to rigorously verify the UX changes:

• test_show_contains_deployment_summary: Captures stdout using capsys to assert that report.show() successfully prints the "Deployment Verdict:" string and subsequent recommendations.
• test_deployment_summary_in_text_report: Asserts the output of _generate_text_report().
• test_deployment_summary_in_html_report: Mocks out the matplotlib summary plot to independently assert the presence of the new HTML deployment block in _repr_html_().

All 9 tests pass successfully.

3. Changelog Documentation

The CHANGELOG.md file was updated to formally record this UX improvement, explicitly stating:

Deployment recommendations are now surfaced directly in TrustReport.show(), text exports, and HTML report views. Users now receive deployment verdicts, primary risk identification, and actionable recommendations without needing to access deployment_summary manually.

📝 Walkthrough

Walkthrough

Deployment recommendations are now automatically displayed across all TrustReport output surfaces: direct console output via show(), plain text exports, and Jupyter HTML representations. The implementation adds deployment summary rendering to each output method and includes comprehensive test coverage validating consistent display of verdicts, risk identification, and recommendations.

Changes

Deployment Recommendation Display

Layer / File(s)	Summary
Console and text report output trustlens/report.py	TrustReport.show() prints deployment summary after score explanation; _generate_text_report() appends deployment summary lines to text output.
HTML deployment verdict card trustlens/report.py	_repr_html_() renders a new deployment verdict section containing verdict, primary risk, per-reason status, and recommendations using deployment_explanation.
Multi-surface output tests tests/test_deployment_explanation.py	Three new tests verify deployment summary renders consistently in show() stdout, _generate_text_report() return value, and _repr_html_() HTML output, including verdict text and recommendation assertions.
Changelog documentation CHANGELOG.md	Unreleased section documents deployment recommendations now surfaced automatically via all output methods without manual deployment_summary access.

155-157: ⚡ Quick win

Strengthen assertions to enforce placement contract, not just presence.

On Line 155 and Line 170 (and similarly in the HTML test on Line 189-191), these checks only verify substring existence. They can still pass if the deployment block moves to the wrong section or if "Fairness" appears elsewhere. Add relative-position assertions (and a more specific HTML marker) so tests enforce the intended UX sequence from the PR objective.

- Around line 1511-1539: The deployment card interpolates unescaped dynamic
content from self.deployment_explanation (used in reasons_html, pr_html,
recs_html and the verdict line) which can lead to HTML/script injection; fix by
HTML-escaping all dynamic values before building the strings (escape
exp["verdict"], each r["message"] in reasons_html, exp["primary_risk"]["metric"]
in pr_html, and each recommendation in recs_html) — e.g., import and use a safe
escaper (html.escape or markupsafe.escape) when constructing reasons_html,
pr_html, recs_html and then concatenate into html.
