Bug: SHA format mismatch causes image scans to fail

The Trivy vulnerability scans reference images using sha-${{ github.sha }} (full 40-character SHA), but the docker/metadata-action creates tags with type=sha,prefix=sha-,format=short which produces only 7 characters (e.g., sha-a1b2c3d). This mismatch means the security scans will never find the images they're supposed to scan, silently defeating the purpose of vulnerability scanning.

Bug: Conditional builds check messages instead of modified files

The android-build and esp32-build jobs use contains(join(github.event.commits.*.message), 'android/') which checks commit messages for the string android/, not whether files in the android/ directory were modified. The documentation and the docs job pattern suggest the intent is to trigger on file changes using *.modified. As written, these builds will only trigger if developers literally write android/ or esp32/ in their commit message, not when they actually change files in those directories.

🔧 Comprehensive Fix for PR #25 Issues

I've analyzed the Cursor Bugbot findings and identified the following issues to fix:

1. ❌ .directory File - KDE Configuration Leaked

Issue: A KDE Dolphin file manager configuration file was accidentally committed.

Fix: This file should be removed and added to .gitignore.

git rm .directory

Add to .gitignore:

# IDE and file manager configs
.directory

---

2. 🐛 Android/ESP32 Build Trigger Logic Bug

Issue: The conditional build triggers check commit messages for strings like android/ instead of checking if files were actually modified.

Current problematic code (.github/workflows/main.yml lines 262 & 317):

if: contains(github.event.head_commit.message, '[android]') || contains(join(github.event.commits.*.message), 'android/') || github.event_name == 'workflow_dispatch'

Problem: contains(join(github.event.commits.*.message), 'android/') checks commit messages for the literal string android/, not file path changes.

Solution: Use GitHub's built-in path filtering or paths-filter action:

Option A: Use workflow path filters (recommended, simpler):

android-build:
  name: 📱 Android Build
  runs-on: ubuntu-latest
  needs: [security]
  # Remove the complex if condition, use path filters at workflow level instead
  
# Add separate workflow trigger at top of file:
on:
  push:
    paths:
      - 'android/**'
    branches: [ main, develop, feature/* ]

Option B: Use dorny/paths-filter action (more flexible):

- uses: dorny/paths-filter@v2
  id: filter
  with:
    filters: |
      android:
        - 'android/**'
      esp32:
        - 'esp32/**'

android-build:
  if: steps.filter.outputs.android == 'true' || contains(github.event.head_commit.message, '[android]')

Recommended fix for main.yml:

Replace lines 262-263:

# OLD (broken):
if: contains(github.event.head_commit.message, '[android]') || contains(join(github.event.commits.*.message), 'android/') || github.event_name == 'workflow_dispatch'

# NEW (fixed):
if: |
  contains(github.event.head_commit.message, '[android]') || 
  github.event_name == 'workflow_dispatch' ||
  (github.event_name == 'push' && contains(github.event.head_commit.modified, 'android/')) ||
  (github.event_name == 'pull_request' && github.event.pull_request.changed_files > 0)

Similar fix needed for ESP32 build (line 317).

3. 🔐 SHA Format Mismatch in Docker Security Scans

Issue: In docker-multiplatform.yml, Trivy scans reference images with full 40-character SHAs (sha-${{ github.sha }}), but Docker tags use short 7-character SHAs (format=short). This causes security scans to fail silently.

Problematic code (.github/workflows/docker-multiplatform.yml line 412):

- name: Extract metadata
  id: meta
  uses: docker/metadata-action@v5
  with:
    tags: |
      type=sha,prefix=sha-,format=short  # ← Creates 7-char SHA
      
# Later...
- name: Run Trivy vulnerability scanner
  with:
    image-ref: '${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}/core-orchestrator:sha-${{ github.sha }}'
    # ↑ References full 40-char SHA - IMAGE NOT FOUND!

Solution: Use consistent SHA format. Two options:

Option A: Use short SHA everywhere (recommended):

- name: Run Trivy vulnerability scanner
  uses: aquasecurity/trivy-action@master
  with:
    # Use short SHA to match the tag
    image-ref: '${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}/core-orchestrator:sha-${{ steps.meta.outputs.version }}'
    format: 'sarif'
    output: 'trivy-core-results.sarif'

Option B: Use full SHA in both places:

# In metadata action, remove format=short:
tags: |
  type=sha,prefix=sha-  # Will use full 40-char SHA

# Trivy will now find the image:
image-ref: '${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}/core-orchestrator:sha-${{ github.sha }}'

Recommended fix: Use Option A with tag from metadata action:

# Lines 412-435 in docker-multiplatform.yml
- name: Run Trivy on Core Orchestrator
  uses: aquasecurity/trivy-action@master
  with:
    image-ref: '${{ steps.meta.outputs.tags }}'  # Use actual built tag
    format: 'sarif'
    output: 'trivy-core-results.sarif'

This affects 4 scan jobs in the workflow (lines 412-435 for all components).

4. ⚠️ Additional Issues

CodeQL C++ Build - Masks Real Failures

Line 87 in main.yml:

- name: Build C++ for CodeQL
  continue-on-error: true  # ← Hides actual build failures

Recommendation: Remove continue-on-error: true or add explicit failure notification:

- name: Build C++ for CodeQL
  id: cpp_build
  continue-on-error: true
  run: |
    # build commands...

- name: Report build status
  if: steps.cpp_build.outcome == 'failure'
  run: |
    echo "::warning::C++ build failed but continuing CodeQL analysis"

Python Dependencies - Ignores Errors

Line 96 in main.yml:

pip install -r requirements.txt || echo "Requirements install completed with warnings"

Issue: Masks real dependency installation failures.

Fix: Make failures visible:

- name: Install Python dependencies
  run: |
    pip install -r requirements.txt || {
      echo "::error::Failed to install requirements"
      exit 1
    }

Would you like me to create a branch with all these fixes applied? I can prepare the exact changes needed for all workflow files.

[sparesparrow]

@cursor Please apply the following fixes to this PR:

1. Remove .directory file and update .gitignore:

   • Delete the .directory file from the repository
   • Add .directory to .gitignore under a new section "# IDE and file manager configs"

2. Fix Android/ESP32 build trigger logic in .github/workflows/main.yml:

   • Line 263: Replace the condition contains(join(github.event.commits.*.message), 'android/') with a proper path-based check
   • Use: contains(github.event.head_commit.message, '[android]') || github.event_name == 'workflow_dispatch'
   • Line 318: Apply the same fix for ESP32 builds, replacing 'android/' check with '[esp32]' check
   • Keep the commit message tags [android] and [esp32] as they work correctly
   • Remove the broken file path checks that search commit messages

3. Fix SHA format mismatch in .github/workflows/docker-multiplatform.yml:

   • Lines 412-435: In all Trivy scan steps, change from:

     image-ref: '${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}/core-orchestrator:sha-${{ github.sha }}'

     To:

     image-ref: '${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}/core-orchestrator:${{ github.ref_name }}-${{ github.sha }}'

   • This applies to all 4 component scans: core-orchestrator, ai-audio-assistant, hardware-bridge, ai-security
   • The issue is that metadata-action creates tags with format=short (7 chars) but Trivy references full SHA (40 chars)

4. Optional improvements in .github/workflows/main.yml:

   • Line 87: Add a warning step after C++ build if it fails (currently continue-on-error: true hides failures)
   • Line 96: Improve error handling for pip install (currently uses || echo which masks failures)

Please commit these changes with the message: fix: workflow conditional logic, Docker SHA format, and remove .directory file

Bug: Integration tests skipped on PRs due to unnecessary dependency

The integration-tests job specifies needs: [python-tests, cpp-builds, docker-builds], but docker-builds only runs on push events to main/develop branches (line 362). When a job in needs is skipped, dependent jobs are also skipped by GitHub Actions. This means integration-tests will never run on pull requests. However, the integration tests use docker-compose -f docker-compose.dev.yml and don't actually consume any artifacts from docker-builds, making this dependency incorrect. The job should likely only depend on python-tests and cpp-builds.

Bug: Docs job incorrectly triggers on commit message text

The documentation job condition checks if commit messages contain the strings 'docs/' or 'mkdocs.yml' using contains(join(github.event.commits.*.message), ...). This causes false triggers when developers mention these strings in commit messages without actually modifying documentation files. The intended behavior is to trigger on file changes, not commit message content. Lines 486-487 correctly check modified files; lines 484-485 appear to be erroneous and would cause unintended documentation builds.
