Subject: [PATCH 01/15] Add search_app_vulnerabilities tool with session
 filtering (mcp-5es)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Create new app-scoped vulnerability search tool consolidating 3 old tools
(list_vulnerabilities, list_vulns_by_app_and_metadata,
list_vulns_by_app_latest_session) into single unified interface.

Features:
- Required appId parameter with validation
- All standard filters (severity, status, environment, dates, tags)
- Session-based filtering: useLatestSession, sessionMetadataName/Value
- Fallback: Returns all app vulns with warning when no session found
- Case-insensitive in-memory session metadata filtering
- Always expands: SESSION_METADATA, SERVER_ENVIRONMENTS, APPLICATION
- Returns PaginatedResponse<VulnLight>

Testing:
- Add 11 comprehensive unit tests
- All 268 unit tests + 50 integration tests passing

Part of Phase 1 of 4-phase vulnerability tool consolidation (mcp-dd4).

Subject: [PATCH 02/15] Add comprehensive unit tests for
 search_app_vulnerabilities (mcp-k7c)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phase 4 of vulnerability consolidation adds 4 critical unit tests:

- useLatestSession fallback: Verifies warning when no session found
- Null SDK response: Tests error handling for null API responses
- Session metadata filtering: Case-insensitive metadata matching with pagination
- Standard filters: Validates all filter parameters pass correctly to SDK

All 270 tests passing (up from 266).

Subject: [PATCH 03/15] Phase 2 & 3: Rename search_vulnerabilities and remove
 old tools (mcp-7sa, mcp-3av)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phase 2 (mcp-7sa):
- Renamed getAllVulnerabilities → searchVulnerabilities
- Renamed tool: list_all_vulnerabilities → search_vulnerabilities
- Removed appId parameter (org-level only)
- Always use getTracesInOrg() endpoint
- Updated tool description with cross-references

Phase 3 (mcp-3av):
- Deleted listVulnsByAppId() (list_vulnerabilities)
- Deleted listVulnsByAppIdAndSessionMetadata() (list_vulns_by_app_and_metadata)
- Deleted listVulnsByAppIdForLatestSession() (list_vulns_by_app_latest_session)
- Migrated integration tests to use search_app_vulnerabilities

Result: 6 vulnerability tools → 4 tools (33% reduction)

All 266 unit tests passing.

Subject: [PATCH 04/15] Fix integration test parameter alignment for
 searchVulnerabilities
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixed compilation errors in AssessServiceIntegrationTest where test calls
were passing parameters in wrong order. The searchVulnerabilities() method
signature has 'statuses' as 4th parameter, but tests were trying to pass
'appId' (which was removed in the org-level consolidation).

Changes:
- Fixed 4 test method calls to use correct parameter order
- Changed 'appId' parameter to 'statuses' in all searchVulnerabilities() calls
- All 270 unit tests pass
- All 50 integration tests pass (6 SAST skipped as expected)

Resolves code review feedback from PR #37 (mcp-jap)

Subject: [PATCH 05/15] Fix null pointer exceptions in session metadata
 filtering and scan results
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addressed two NPE issues identified by codex autonomous agent:

1. **AssessService** (mcp-d7h): Fixed NullPointerException in search_app_vulnerabilities
   when sessionMetadataValue or metadataItem.getValue() is null.
   - Treat null sessionMetadataValue as wildcard (match on name only)
   - Add null check for metadataItem.getValue() before equalsIgnoreCase
   - Added 2 unit tests covering both null scenarios

2. **SastService** (mcp-dvf): Fixed NullPointerException in get_scan_results when
   project.lastScanId() is null (common for projects with no completed scans).
   - Check if lastScanId is null before calling scans.get()
   - Check if scan is null after retrieval
   - Return descriptive IOException with clear user-facing message
   - Updated existing test + added new test for null scan scenario

All 272 unit tests passing.

 - `in_progress` → Actively working on task (SET THIS WHEN YOU START!)
 - `closed` → Task complete, tested, and merged
 
+### Human Review Required Label
+
+**IMPORTANT: Beads labeled `needs-human-review` require human approval before AI work begins.**
+
+**AI Behavior:**
+- Before starting work on any bead, check for the `needs-human-review` label
+- If present, **DO NOT start work** on the bead
+- Instead, ask the human to review the bead description and approach
+- Once human reviews and approves, they will remove the `needs-human-review` label
+- Only after label is removed may AI proceed with implementation
+
+**Example workflow:**
+```
+AI: "I see bead mcp-xyz is ready to work on, but it has the 'needs-human-review' label.
+     Please review the bead description and let me know if the approach looks good.
+     Once approved, remove the label and I'll proceed with implementation."
+```
+
+### Human Review Label Workflow
+
+**When a human reviews a bead with the `needs-human-review` label:**
+
+1. **Review the bead description** - Evaluate the proposed approach, implementation details, and any concerns
+2. **Update the bead** - If changes are needed based on review, update the bead description with the approved approach
+3. **Update labels:**
+   ```bash
+   bd label remove <bead-id> needs-human-review
+   bd label add <bead-id> human-reviewed
+   ```
+4. **Proceed to next bead** - Continue reviewing remaining beads with `needs-human-review` label
+
+**Label meanings:**
+- `needs-human-review` - Bead requires human approval before AI can start work
+- `human-reviewed` - Bead has been reviewed and approved by human, AI may proceed when ready
+
 ### AI Model Labeling
 
 **When a bead is worked on by an AI system, label it to track which model performed the work:**

Subject: [PATCH 07/15] Fix useLatestSession flag to work independently without
 sessionMetadataName (mcp-b9y)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Problem
The useLatestSession parameter only worked when sessionMetadataName was also
provided. When used alone, it silently did nothing and returned vulnerabilities
from ALL sessions.

Root cause: The code had two separate filter objects (filterForm and filterBody)
with two API call paths. The agent session ID was set on filterBody, but when
sessionMetadataName was NOT provided, the code used filterForm (which lacked the
session ID), causing the filter to be lost.

## Solution: Unified In-Memory Session Filtering
- Eliminated filterBody object entirely - use only filterForm
- All session filtering (useLatestSession AND sessionMetadataName) now happens
  consistently in-memory after fetching from the API
- One filter object, one code path for session filtering
- Removed mutual exclusivity validation - both filters can now work together

## Changes
- AssessService.java:
  - Removed filterBody creation and manual field copying (lines 701-721)
  - Unified session filtering logic using needsInMemorySessionFiltering flag
  - Added agent session ID filtering before sessionMetadataName filtering
  - Updated pagination to handle both filter types
  - Removed validation preventing both filters from being used together

- AssessServiceTest.java:
  - Updated mutual exclusivity test to verify both filters work together
  - Added test: useLatestSession works alone (main bug fix verification)
  - Fixed existing session metadata tests to use new 3-parameter getTraces API
  - Added lenient stubbing for mocks that may not be accessed

## Expected Outcomes
✅ useLatestSession works independently (no sessionMetadataName required)
✅ Both filters can be combined (useLatestSession + sessionMetadataName)
✅ Simplified architecture (one filter object, one code path)
✅ Consistent behavior (all session filtering is in-memory)
✅ Proper pagination (works for all filtering scenarios)

## Testing
All 274 tests pass including:
- New test: searchAppVulnerabilities_should_filter_by_useLatestSession_alone
- New test: searchAppVulnerabilities_should_support_both_useLatestSession_and_sessionMetadataName_together
- All existing session metadata filtering tests updated and passing

Subject: [PATCH 08/15] Change sessionMetadataValue logging from INFO to DEBUG
 level (mcp-wts)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Session metadata values can contain sensitive information like branch names,
build IDs, environment names, and developer identifiers. Logging these at
INFO level means they appear in production logs where they may be exposed
to unauthorized viewers.

This change moves the log statement in searchAppVulnerabilities from INFO
to DEBUG level, ensuring sensitive session metadata values are only logged
when DEBUG logging is explicitly enabled.

Changes:
- AssessService.java:629 - Changed log.info() to log.debug()

Subject: [PATCH 09/15] Add verification tests for status filter fix (mcp-3sy)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added 3 unit tests to verify status filters work correctly after mcp-b9y's
unified refactoring eliminated the filterBody object:

1. searchAppVulnerabilities_should_apply_status_filters_with_sessionMetadataName()
   - Verifies explicit status filters are passed to SDK when using sessionMetadataName
   - Uses ArgumentCaptor to verify SDK receives status filters

2. searchAppVulnerabilities_should_apply_status_filters_with_useLatestSession()
   - Verifies explicit status filters are passed to SDK when using useLatestSession
   - Tests that status filtering works independently with session ID filtering

3. searchAppVulnerabilities_should_use_smart_defaults_with_sessionMetadataName()
   - Verifies smart default statuses (Reported, Suspicious, Confirmed) are applied
   - Confirms Fixed and Remediated are excluded from smart defaults
   - Tests status filtering with session metadata filtering combined

All tests use ArgumentCaptor to verify the CRITICAL fix: status filters are now
always passed to SDK in the filterForm, regardless of session filtering mode.
This verifies the bug is fixed by the unified architecture approach.

 field discovery (mcp-b7s)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Update sessionMetadataName @ToolParam: Document case-insensitive matching,
  guide users to call get_session_metadata(appId) to discover available fields
- Update sessionMetadataValue @ToolParam: Document case-insensitive matching,
  guide users to discover values via get_session_metadata(appId)
- Remove hardcoded examples (Branch, Environment) that suggested fixed fields
- Session metadata fields are dynamic per-customer configuration, not enums

Subject: [PATCH 11/15] Fix vulnerability duplication in session metadata
 filtering (mcp-oj2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problem:
- When filtering by sessionMetadataName, vulnerabilities appearing in multiple
  sessions were added to results multiple times
- Caused inflated totals, broken pagination, and duplicate entries
- Common scenario: vuln found in both "main" and "develop" branches

Root Cause:
- Nested loop used `break` which only exited innermost loop
- Code continued iterating over remaining SessionMetadata objects
- Same vulnerability added multiple times if it matched in multiple sessions

Solution:
- Added labeled break `sessionLoop:` on SessionMetadata loop
- Changed `break` to `break sessionLoop` to exit both inner loops
- Ensures each vulnerability appears at most once in results
- Continues processing other vulnerabilities correctly

Test Coverage:
- Added test case for vulnerability with 2 matching session metadata objects
- Verifies vulnerability appears exactly once (not duplicated)
- All existing tests pass (62 tests total)

Benefits:
- Accurate pagination counts
- No duplicate vulnerabilities in results
- Slight performance improvement (stops after first match per vuln)

Subject: [PATCH 12/15] Add anonymous builder pattern for test mock objects
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement anonymous builders following established pattern from
AnonymousApplicationBuilder to reduce test boilerplate and improve
readability. Created 6 builders total (3 in this commit, 3 previously):

New builders in this commit:
- AnonymousMetadataItemBuilder: Simple metadata item mocking
- AnonymousTraceBuilder: Complex trace mocking with SessionMetadata helpers
- AnonymousProjectBuilder: SAST Project interface mocking

Previously committed builders:
- AnonymousSessionMetadataBuilder: Session metadata with MetadataItem lists
- AnonymousScanBuilder: SAST Scan interface mocking with SARIF support
- AnonymousLibraryExtendedBuilder: SCA library mocking with many fields

Refactored test files:
- AssessServiceTest: 20+ trace mocks simplified (SessionMetadata patterns)
- SastServiceTest: All 5 Project and 1 Scan mocks refactored
- SCAServiceTest: All 3 LibraryExtended helper methods refactored

Benefits:
- Reduces 10+ lines of mock setup to 1-3 lines per object
- Lenient stubbing avoids UnnecessaryStubbingException
- Fluent API improves test readability
- Convenience methods simplify complex nested object creation

All 278 tests pass. Addresses mcp-hyj.

Subject: [PATCH 13/15] Fix route coverage parameter validation for
 sessionMetadataValue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add symmetric validation to reject sessionMetadataValue when provided
without sessionMetadataName. Previously, the tool silently ignored
sessionMetadataValue in this scenario, causing users to receive
unfiltered results without any indication of the misconfiguration.

Changes:
- Added validation check rejecting null/empty sessionMetadataName with
  non-null sessionMetadataValue (mirrors existing reverse check)
- Updated @Tool description with explicit note about parameter dependency
- Updated JavaDoc for both parameters stating "Must be provided with..."
- Updated @throws documentation to cover both validation directions

Testing:
- Added testGetRouteCoverage_SessionMetadataValue_WithoutName() test
- Added testGetRouteCoverage_SessionMetadataValue_WithEmptyName() test
- All 327 tests passing (26 RouteCoverageService tests)

Users now receive immediate, clear error messages instead of silently
incorrect results. AI models consuming the tool see explicit
documentation about the parameter dependency.

Addresses mcp-rlc.

Subject: [PATCH 14/15] Fix NullPointerException when filtering applications by
 tag (mcp-7jf)

Establish "never null collections" pattern across Application class:
- Add defensive getters for all collection fields (tags, techs, roles,
  policies, metadataEntities, validationErrorFields, missingRequiredFields)
- Update AnonymousApplicationBuilder to enforce pattern in tests
- Simplify AssessService.matchesMetadataFilter() (no null check needed)
- Add test for untagged apps scenario
- Update ApplicationJsonParsingTest to expect empty list instead of null

This prevents NPE when filtering by tag on apps that have no tags
(extremely common default state in most organizations).

Subject: [PATCH 15/15] Remove unused appId parameter from
 VulnerabilityFilterParams (mcp-m0x)

Remove dead code: appId field was stored but never accessed in production.
Routing is explicit in AssessService via different SDK calls, so appId
in VulnerabilityFilterParams served no purpose.

Changes:
- Remove appId from record definition and of() method (7 args now, was 8)
- Update 2 call sites in AssessService.java
- Remove testAppIdPassedThrough test, update all others to 7 args

All 280 tests passing.
