Replace the always-force container removal (SIGKILL) with a two-phase
approach: first attempt graceful stop (SIGTERM with configurable timeout),
then remove without force. Falls back to force remove only if the graceful
path fails. The graceful stop timeout is configurable via
orchestrator.sandbox.gracefulStopTimeoutSeconds (default: 10s).

Add per-agent mutex using promise chaining to serialize state transitions
for the same agent. This prevents the Time-of-Check-Time-of-Use race
condition where two concurrent requests could both read the current state,
both validate it as valid for transition, and both write, causing one to
overwrite the other's transition.
The mutex uses a Map<string, Promise<void>> with promise chaining so that:
- Concurrent transitions to the same agent are queued and executed sequentially
- Different agents can still transition concurrently without contention
- The lock is always released even if the transition throws an error

Replace Promise.all of individual findUnique queries per tag with a
single findMany batch query. Only missing tags are created individually.
Tag associations now use createMany instead of individual creates.
Also deduplicates tags by slug via Map, preventing duplicate entries.

Add validateImageTag() method to DockerSandboxService that validates
Docker image references against a safe character pattern before any
container creation. Rejects empty tags, tags exceeding 256 characters,
and tags containing shell metacharacters (;, &, |, $, backtick, etc.)
to prevent injection attacks. Also validates the default image tag at
service construction time to fail fast on misconfiguration.

Change default bind address from 0.0.0.0 to 127.0.0.1 to prevent
the orchestrator API from being exposed on all network interfaces.
The bind address is now configurable via HOST or BIND_ADDRESS env
vars for Docker/production deployments that need 0.0.0.0.

The CurrentUser decorator previously returned undefined when no user was
found on the request object. This silently propagated undefined to
downstream code, risking null reference errors or authorization bypasses.
Now throws UnauthorizedException when user is missing, providing
defense-in-depth beyond the AuthGuard. All controllers using
@CurrentUser() already have AuthGuard applied, so this is a safety net.
Added comprehensive test suite for the decorator covering:
- User present on request (happy path)
- User with optional fields
- Missing user throws UnauthorizedException
- Request without user property throws UnauthorizedException
- Data parameter is ignored

Replace inline type annotations with proper class-validator DTOs for the
semantic and hybrid search endpoints. Adds SemanticSearchBodyDto,
HybridSearchBodyDto (query: @IsString @MaxLength(500), status:
@IsOptional @IsEnum(EntryStatus)), and SemanticSearchQueryDto (page/limit
with @IsInt @Min/@Max validation). Includes 22 new tests covering DTO
validation edge cases and controller integration.

- Add defensive validation in BrainService.search and BrainService.query methods:
- Reject search terms exceeding 500 characters with BadRequestException
- Clamp limit to valid range [1, 100] for defense-in-depth
- Add comprehensive tests for DTO validation and service-level guards
- Update existing controller tests for new search method signature

Remove data: from allowedSchemesByTag for img tags and add transformTags

Add AbortController to cancel in-flight search requests when a new
search fires, preventing stale results from overwriting newer ones.
The controller is also aborted on component unmount for cleanup.
Switched from apiGet to apiRequest to support passing AbortSignal.
Added 3 new tests verifying signal passing, abort on new search,
and abort on unmount.

The debounced search useEffect accessed `filters` and `onFilterChange`
without including them in the dependency array. Fixed by:
- Using useRef for onFilterChange to maintain a stable reference
- Using functional state update (setFilters callback) to access
previous filters without needing it as a dependency
This prevents stale closures while avoiding infinite re-render loops
that would occur if these values were added directly to the dep array.

Orchestrator was editing source code directly instead of spawning workers.

The test "should verify exponential backoff timing" was creating a promise

Addresses threshold-satisficing behavior where agent declared success
at 91% and moved on. New protocol requires:
- Bulk Phase (90%): Fast progress on tractable errors
- Polish Phase (100%): Triage remaining into categories
- Phase Boundary Rule: Must complete Polish before proceeding
- Documentation: All deferrals documented with rationale
Transforms "78 errors acceptable" into traceable technical decisions.

The fulltext-search integration tests require PostgreSQL trigger
function and GIN index that may not be present in all environments
(e.g., CI database). This change adds dynamic detection of the
trigger function and gracefully skips tests that require it.
- Add isFulltextSearchConfigured() helper to check for trigger
- Skip trigger/index tests with clear console warnings
- Keep schema validation test (column exists) always running

Two fixes for CI test failures:
1. secret-scanner.service.spec.ts - "unreadable files" test:
- The test uses chmod 0o000 to make a file unreadable
- In CI (Docker), tests run as root where chmod doesn't prevent reads
- Fix: Detect if running as root with process.getuid() and adjust
expectations accordingly (root can still read the file)
2. demo/kanban/page.tsx - Build failure during static generation:
- KanbanBoard component uses useToast() hook from @mosaic/ui
- During Next.js static generation, ToastProvider context is not available
- Fix: Wrap page content with ToastProvider to provide context
Quality gates verified locally:
- lint: pass
- typecheck: pass
- orchestrator tests: 612 passing
- web tests: 650 passing (23 skipped)
- web build: pass (/demo/kanban now prerendered successfully)

Fixed 27 test failures by addressing several categories of issues:
Security spec tests (coordinator-integration, stitcher):
- Changed async test assertions to synchronous since ApiKeyGuard.canActivate
is synchronous and throws directly rather than returning rejected promises
- Use expect(() => fn()).toThrow() instead of await expect(fn()).rejects.toThrow()
Federation controller tests:
- Added CsrfGuard and WorkspaceGuard mock overrides to test module
- Set DEFAULT_WORKSPACE_ID environment variable for handleIncomingConnection tests
- Added proper afterEach cleanup for environment variable restoration
Federation service tests:
- Updated RSA key generation tests to use Vitest 4.x timeout syntax
(second argument as options object, not third argument)
Prisma service tests:
- Replaced vi.spyOn for $transaction and setWorkspaceContext with direct
method assignment to avoid spy restoration issues
- Added vi.clearAllMocks() in afterEach to properly reset between tests
Integration tests (job-events, fulltext-search):
- Added conditional skip when DATABASE_URL is not set to prevent failures
in environments without database access
Remaining 7 failures are pre-existing fulltext-search integration tests
that require specific PostgreSQL triggers not present in test database.

- Activity logging now returns null on DB errors per security fix
3. SecretScannerService unreadable file test:
- Handle root user case where chmod 0o000 doesn't prevent reads
- Test now adapts expectations based on runtime permissions

Implement circuit breaker pattern to prevent infinite retry loops on
repeated failures (SEC-ORCH-7). The circuit breaker tracks consecutive
failures and opens after a threshold is reached, blocking further
requests until a cooldown period elapses.
Circuit breaker states:
- CLOSED: Normal operation, requests pass through
- OPEN: After N consecutive failures, all requests blocked
- HALF_OPEN: After cooldown, allow one test request
Changes:
- Add circuit_breaker.py with CircuitBreaker class
- Integrate circuit breaker into Coordinator.start() loop
- Integrate circuit breaker into OrchestrationLoop.start() loop
- Integrate per-agent circuit breakers into ContextMonitor
- Add comprehensive tests for circuit breaker behavior
- Log state transitions and circuit breaker stats on shutdown
Configuration (defaults):
- failure_threshold: 5 consecutive failures
- cooldown_seconds: 30 seconds
