- Centered content in RequestPermissionSample, RequestMultiplePermissionsSample, and RequestLocationPermissionsSample using Box and Alignment.Center.
- Updated text messaging to be more professional and clear (e.g., "The camera permission is required for this feature").
- Implemented human-friendly permission names in RequestMultiplePermissionsSample, mapping technical strings like "android.permission.CAMERA" to "camera".
- Applied TextAlign.Center to all text blocks for a more polished and centered presentation.

Ensures that only activities from the same package are displayed in the
sample app's main list. This prevents malicious external apps from
injecting themselves into the UI by declaring the same intent category.

+## 2025-05-14 - [Activity Injection in Sample App Launcher]
+**Vulnerability:** The sample application's `MainActivity` used `queryIntentActivities` to dynamically populate its list of samples based on an intent category (`com.google.accompanist.sample.SAMPLE_CODE`) without verifying the package name of the returned activities.
+**Learning:** Malicious external applications could register activities with the same category and inject themselves into the sample app's UI, potentially leading to phishing or UI redressing attacks.
+**Prevention:** Always verify that `info.activityInfo.packageName` matches the application's own `packageName` when dynamically loading components from `PackageManager` based on shared intent categories.

- Added illustrative icons (Checkmark, Face) to provide visual context and feedback.
- Improved spacing with `Arrangement.spacedBy(16.dp)` in `Column` layouts.
- Updated button labels to be more specific and action-oriented (e.g., "Allow camera access").
- Ensured consistent implementation across `RequestPermissionSample`, `RequestMultiplePermissionsSample`, and `RequestLocationPermissionsSample`.

+## 2024-05-22 - [Permission Samples UX]
+**Learning:** Enhancing permission rationale screens with illustrative icons and specific action-oriented button labels (e.g., "Allow camera access" vs. "Request permission") improves user trust and clarity. Using `Arrangement.spacedBy` in `Column` ensures consistent visual rhythm without manual spacers.
+**Action:** Use `Icons.Default.Face` for rationale prompts and `Icons.Default.Done` with success colors for granted states in Compose-based permission flows.

Subject: [PATCH 04/12] Harden sample app security posture

- Set `android:exported="false"` for internal sample activities to follow the principle of least privilege.
- Add `android:usesCleartextTraffic="false"` to prevent unencrypted network traffic.
- Rename `EXTRA_PATH` in `MainActivity` to use a project-specific prefix, avoiding potential intent collisions.
- Add security rationale comments to `AndroidManifest.xml`.

- Replace MD5 with SHA-256 in checksum.sh for better integrity verification.
- Add fallback to openssl if sha256sum is missing.
- Hardened script with proper variable quoting to prevent word-splitting issues.
- Update sentinel journal with learnings.

 **Vulnerability:** The sample application's `MainActivity` used `queryIntentActivities` to dynamically populate its list of samples based on an intent category (`com.google.accompanist.sample.SAMPLE_CODE`) without verifying the package name of the returned activities.
 **Learning:** Malicious external applications could register activities with the same category and inject themselves into the sample app's UI, potentially leading to phishing or UI redressing attacks.
 **Prevention:** Always verify that `info.activityInfo.packageName` matches the application's own `packageName` when dynamically loading components from `PackageManager` based on shared intent categories.

+## 2024-05-15 - [Insecure Hashing and Shell Script Weakness]
+**Vulnerability:** The `checksum.sh` script used MD5 for integrity checks and lacked variable quoting, making it susceptible to collisions and word-splitting vulnerabilities.
+**Learning:** Legacy scripts often use older hashing algorithms like MD5 which are cryptographically broken. Additionally, unquoted variables in shell scripts can lead to unintended execution or script failure if paths contain special characters.
+**Prevention:** Use SHA-256 for all integrity and security-sensitive hashing. Always wrap shell variables in double quotes (e.g., `"$VAR"`) to prevent word-splitting and globbing attacks.

I have upgraded the SCM connection and License URLs in gradle.properties from insecure protocols (git:// and http://) to HTTPS. This follows security best practices and ensures encrypted transport for project metadata and source repository connections.

🚨 Severity: MEDIUM
💡 Vulnerability: Use of unencrypted/unauthenticated protocols for metadata.
🎯 Impact: Potential for MITM attacks or metadata spoofing.
🔧 Fix: Upgraded URLs to HTTPS.
✅ Verification: Verified via codebase search and successful build/test execution.

Added a trailing chevron icon to the list items on the main screen to provide a visual cue that they are interactive and navigable.

- Added necessary icon-related imports to `MainScreen.kt`.
- Updated `ListItem` in `ContentList` to include `trailingContent` with `Icons.AutoMirrored.Filled.KeyboardArrowRight`.
- Verified changes with code review, compilation, and unit tests.
- Cleaned up temporary test files.

Hardened release/signing-setup.sh and checksum.sh to improve security
and robustness.

- Switch openssl from -k to -pass env:ENCRYPT_KEY to avoid secret
  exposure in process listings.
- Add 'set -e' for fail-fast behavior.
- Use proper variable quoting throughout.
- Fix checksum.sh openssl fallback for filenames with spaces.
- Update .jules/sentinel.md with learnings.

 **Vulnerability:** The `checksum.sh` script used MD5 for integrity checks and lacked variable quoting, making it susceptible to collisions and word-splitting vulnerabilities.
 **Learning:** Legacy scripts often use older hashing algorithms like MD5 which are cryptographically broken. Additionally, unquoted variables in shell scripts can lead to unintended execution or script failure if paths contain special characters.
 **Prevention:** Use SHA-256 for all integrity and security-sensitive hashing. Always wrap shell variables in double quotes (e.g., `"$VAR"`) to prevent word-splitting and globbing attacks.

+## 2024-05-16 - [Secret Exposure in Process List via openssl -k]
+**Vulnerability:** The `release/signing-setup.sh` script used the legacy `openssl -k` flag to pass an encryption key as a command-line argument, making it visible to all users on the system via process monitoring tools.
+**Learning:** Command-line arguments are inherently public on most systems. Using them for secrets is a major security risk, especially in shared CI/CD environments.
+**Prevention:** Always use environment variables, files, or descriptor-based methods to pass secrets to CLI tools. In `openssl`, use `-pass env:VARIABLE_NAME` to read the secret from an environment variable securely.

 ## 2024-05-22 - [Permission Samples UX]
 **Learning:** Enhancing permission rationale screens with illustrative icons and specific action-oriented button labels (e.g., "Allow camera access" vs. "Request permission") improves user trust and clarity. Using `Arrangement.spacedBy` in `Column` ensures consistent visual rhythm without manual spacers.
 **Action:** Use `Icons.Default.Face` for rationale prompts and `Icons.Default.Done` with success colors for granted states in Compose-based permission flows.

- Lifted selectedIcon state to Activity level in NavRail and NavDrawer samples.
- Display selected icon and name in the main content area for visual feedback.
- Set contentDescription = null on navigation icons to avoid redundancy with labels.
- Updated .jules/palette.md with UX/accessibility learnings.

- Lifted selectedIcon state to Activity level in NavRail and NavDrawer samples.
- Display selected icon and name in the main content area for visual feedback.
- Set contentDescription = null on navigation icons to avoid redundancy with labels.
- Hardened release/signing-setup.sh to skip decryption if key is missing (fixes fork PRs).
- Updated workflows to pass ENCRYPT_KEY via environment variables for security and compatibility.
- Updated .jules/palette.md with UX/accessibility learnings.
