+# AWS Support Evidence Package
+
+Issue #55 includes a final evidence package for requesting AWS restriction review after the StudentHub S3/IAM remediation is complete. Keep raw screenshots, CloudTrail exports, IAM CSV files, Railway screens, candidate records, and full key IDs in a private incident folder. This helper only produces a redacted Markdown summary that can be reviewed before sending to AWS Support.
+
+## Usage
+
+Prepare a private JSON manifest using the sample shape in `tools/fixtures/aws-support-evidence-package.sample.json`, then run:
+
+```bash
+node tools/build-aws-support-evidence-package.mjs private/aws-support-evidence.json > private/aws-support-evidence.md
+```
+
+The generated report redacts:
+
+- 12-digit AWS account IDs
+- AWS access-key-looking values
+- long secret-like token strings
+
+It preserves short key suffixes such as `FZMN`, `4T67K`, `ODY2X`, and `WCUM` because issue #55 uses suffixes as the public-safe reference format.
+
+## Manifest Sections
+
+The manifest should contain only evidence summaries and local/private file references:
+
+- `deletedKeys`: inactive key suffixes deleted after screenshots were captured
+- `rotatedKeys`: exposed or over-permissioned key suffixes rotated or replaced
+- `environmentVariables`: replacement variable names configured in Railway/secret stores
+- `bucketControls`: S3 lifecycle, CORS, versioning, logging, replication, and public-access evidence
+- `smokeTests`: post-remediation upload, remove, replace, staff-view, and key-deactivation tests
+- `cloudTrail`: investigation summaries with source IP, user agent, event, bucket, and key suffix only
+- `iamReviews`: least-privilege/access-analyzer review summaries
+- `supportNotes`: remaining limitations, private attachment locations, or follow-up owner notes
+
+Do not put full keys, secret keys, bearer tokens, raw CloudTrail JSON, candidate Civil ID values/images, phone numbers, account IDs, or payment/tax data into the manifest.
+
+## Validation
+
+Run the local regression check before committing changes to this helper:
