# BLOCKED Tasks Dependency Tree

> **Last Updated:** 2025-12-04 (12 specs + 2 implementations = ~74+ tasks unblocked)
> **Purpose:** This document maps all BLOCKED tasks and their root causes to help teams prioritize unblocking work.

## How to Use This Document

Before starting work on any BLOCKED task, check this tree to understand:
1. What is the **root blocker** (external dependency, missing spec, staffing, etc.)
2. What **chain of tasks** depends on it
3. Which team/guild owns the root blocker

---

## Legend

- **Root Blocker** — External/system cause (missing spec, staffing, disk space, etc.)
- **Chained Blocked** — Blocked by another BLOCKED task
- **Module** — Module/guild name

## 8.1 CLI COMPILE FAILURES (Detailed Analysis)

> **Analysis Date:** 2025-12-04
> **Status:** ✅ **RESOLVED** (2025-12-04)
> **Resolution:** See `docs/implplan/CLI_AUTH_MIGRATION_PLAN.md`

The CLI (`src/Cli/StellaOps.Cli`) had significant API drift from its dependencies. This has been resolved.

### Remediation Summary (All Fixed)

| Library | Issue | Status |
|---------|-------|--------|
| `StellaOps.Auth.Client` | `IStellaOpsTokenClient` interface changed | ✅ **FIXED** - Extension methods created |
| `StellaOps.Cli.Output` | `CliError` constructor change | ✅ **FIXED** |
| `System.CommandLine` | API changes in 2.0.0-beta5+ | ✅ **FIXED** |
| `Spectre.Console` | `Table.AddRow` signature change | ✅ **FIXED** |
| `BackendOperationsClient` | `CreateFailureDetailsAsync` return type | ✅ **FIXED** |
| `CliProfile` | Class→Record conversion | ✅ **FIXED** |
| `X509Certificate2` | Missing using directive | ✅ **FIXED** |
| `StellaOps.PolicyDsl` | `PolicyIssue` properties changed | ✅ **FIXED** |
| `CommandHandlers` | Method signature mismatches | ✅ **FIXED** |

### Build Result

**Build succeeded with 0 errors, 6 warnings** (warnings are non-blocking)

### Previously Blocked Tasks (Now Unblocked)

```
CLI Compile Failures (RESOLVED)
    +-- CLI-ATTEST-73-001: stella attest sign           → UNBLOCKED
    +-- CLI-ATTEST-73-002: stella attest verify         → UNBLOCKED
    +-- CLI-AIAI-31-001: Advisory AI CLI integration    → UNBLOCKED
    +-- CLI-AIRGAP-56-001: stella mirror create         → UNBLOCKED
    +-- CLI-401-007: Reachability evidence chain        → UNBLOCKED
    +-- CLI-401-021: Reachability chain CI/attestor     → UNBLOCKED
```

### Key Changes Made

1. Created `src/Cli/StellaOps.Cli/Extensions/StellaOpsTokenClientExtensions.cs` with compatibility shims
2. Updated 8 service files to use new Auth.Client API pattern
3. Fixed CommandFactory.cs method call argument order/types
4. Updated PolicyDiagnostic model (Path instead of Line/Column/Span/Suggestion)
5. Fixed CommandHandlers.cs static type and diagnostic rendering

## 8.2 BUILD VERIFICATION (2025-12-04)

> **Verification Date:** 2025-12-04
> **Purpose:** Verify current build status and identify remaining compile blockers

### Findings

**✅ CLI Build Status**
- **Status:** CONFIRMED WORKING
- **Build Result:** 0 errors, 8 warnings (non-blocking)
- **Command:** `dotnet build src/Cli/StellaOps.Cli/StellaOps.Cli.csproj -p:NuGetAudit=false`
- **Note:** NuGet audit disabled due to mirror connectivity issues (not a code issue)
- **Warnings:**
  - Obsolete API usage (AWS KMS, X509Certificate2, StellaOpsScopes)
  - Nullable type warnings in OutputRenderer.cs
  - Unused variable in CommandHandlers.cs

**✅ Scanner Analyzer Builds**
- **PHP Analyzer:** ✅ BUILDS (0 errors, 0 warnings)
- **Java Analyzer:** ✅ BUILDS (0 errors, 0 warnings)
- **Ruby, Node, Python analyzers:** ✅ ALL BUILD (verified via CLI dependency build)

**Conclusion:** Scanner analyzer "compile failures" mentioned in Section 6 and 8 are **NOT actual compilation errors**. The blockers are about:
- Missing specifications/fixtures (PHP analyzer bootstrap spec)
- Missing contracts (EntryTrace, SCANNER-SURFACE-01)
- Test environment issues (not build issues)

**✅ Disk Space Status**
- **Current Usage:** 78% (185GB used, 54GB available)
- **Assessment:** NOT A BLOCKER
- **Note:** AirGap "disk full" blockers (Section 5.1-5.3) may refer to different environment or are outdated

### Updated Blocker Classification

The following items from Section 8 are **specification/contract blockers**, NOT compile blockers:
- SCANNER-ANALYZERS-PHP-27-001: Needs spec/fixtures, compiles fine
- SCANNER-ANALYZERS-JAVA-21-007: Builds successfully
- ANALYZERS-LANG-11-001: Blocked by test environment, not compilation

**Recommended Actions:**
1. Remove "Scanner analyzer compile failures" from blocker descriptions
2. Reclassify as "Scanner analyzer specification/contract gaps"
3. Focus efforts on creating missing specs rather than fixing compile errors

---
