## §2.0.0 Contract Integrity

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | yes | Issue and self-coherence clearly distinguish problem (scanner misses inbox) vs expected (should scan inbox). No false shipped claims. |
| Canonical sources/paths verified | yes | Paths `src/go/internal/activate/activate.go:232` and `activate_test.go:70` verified present and accurate. |
| Scope/non-goals consistent | yes | Scope is minimal addition to existing scanner. No contradiction with "maintain existing functionality" constraint. |
| Constraint strata consistent | n/a | No constraint strata defined in this simple bugfix issue. |
| Exceptions field-specific/reasoned | n/a | No exceptions claimed or required. |
| Path resolution base explicit | yes | File paths are repo-root relative and explicit. Line numbers provided for verification. |
| Proof shape adequate | yes | Test fixture updated to include `threads/inbox` in minimal hub creation. Adequate for this local change. |
| Cross-surface projections updated | yes | Test fixture properly updated. No other projections required for internal scanner function. |
| No witness theater / false closure | yes | No false enforcement claims. Simple function addition with honest test coverage. |
| PR body matches branch files | n/a | Direct branch commits, no PR body to verify consistency against. |

**Contract integrity status:** ✅ ALL CHECKS PASS — proceeding to implementation review.

## §2.0 Issue Contract

### AC Coverage
| # | AC | In diff? | Status | Notes |
|---|----|----------|--------|-------|
| AC1 | `cn activate` should scan `threads/inbox/` in addition to existing surfaces | yes | ✓ MET | Line 233: added `"threads/inbox"` to candidates slice in `scanThreads()` |
| AC2 | Activation output should include `threads/inbox: present` when directory exists | yes | ✓ MET | Function returns paths from `presentPaths()` which checks directory existence |
| AC3 | Implementation should maintain existing functionality for current surfaces | yes | ✓ MET | No existing lines changed, only addition to candidates list |

### Named Doc Updates
| Doc / File | In diff? | Status | Notes |
|------------|----------|--------|-------|
| N/A | N/A | N/A | No named doc updates required per issue or self-coherence |

### CDD Artifact Contract
| Artifact | Required? | Present? | Notes |
|----------|-----------|----------|-------|
| self-coherence.md | yes | yes | Complete with Gap, Skills, ACs, Self-check, Debt, CDD-Trace sections |
| alpha-closeout.md | optional | no | Small change - "no findings" implicit per CDD.md §1.2 table |
| bootstrap stubs | no | no | Not required for small change per self-coherence |

### Active Skill Consistency  
| Skill | Required by | Loaded? | Applied? | Notes |
|-------|-------------|---------|----------|-------|
| eng/go | Tier 2 coding bundle | yes | yes | Small package change, pure addition to slice - follows go patterns |
| eng/ux-cli | Tier 2 coding bundle | yes | yes | Maintains existing output format, adds info appropriately |
| eng/test | Tier 2 coding bundle | yes | yes | Updated test fixture to include new path for coverage |

## §2.1 Diff and Context Inspection

**2.1.1 Structural closure:** ✓ N/A — No structural prevention claims made  
**2.1.2 Multi-format parity:** ✓ N/A — No multi-format values involved  
**2.1.3 Snapshot consistency:** ✓ N/A — No snapshot tests affected  
**2.1.4 Stale-path validation:** ✓ N/A — No paths moved, renamed, or deleted  
**2.1.5 Branch naming:** ✓ PASS — `cycle/323` follows project convention  
**2.1.6 Execution timeline:** ✓ N/A — No process boundaries crossed  
**2.1.7 Derivation vs validation:** ✓ N/A — No single source of truth claims  
**2.1.8 Authority-surface conflict:** ✓ PASS — No conflicts found between issue, self-coherence, and implementation. Single canonical function `scanThreads()` modified.  
**2.1.9 Module-truth audit:** ✓ PASS — Checked `activate.go` for similar assumptions. `scanMemory()` follows same pattern with reflections paths. No other thread path assumptions found.  
**2.1.10 Contract confinement:** ✓ PASS — `scanThreads()` correctly delegates existence checking to `presentPaths()`, which uses `os.Stat()`. No silent acceptance of unclaimed inputs.  
**2.1.11 Architecture leverage:** ✓ PASS — Minimal fix appropriate for scope. Adding one missing path to existing scanner is correct level of intervention.  
**2.1.12 Process overhead:** ✓ N/A — No new docs, artifacts, gates, or procedures added  
**2.1.13 Design constraints:** ✓ N/A — No project design constraints document found to validate against

## §2.2 Architecture and Design Check

**Architecture check:** NOT ACTIVE — Change does not touch package boundaries, command/provider/orchestrator/skill separation, source/artifact/installed flow, registry design, kernel vs package responsibility, transport vs protocol semantics, or command dispatch vs domain logic. This is a simple addition to an existing data list within a single internal function.

## Findings

| # | Finding | Evidence | Severity | Type |
|---|---------|----------|----------|------|
| - | No findings | Review complete across all phases | N/A | N/A |

## CI Status

✅ **CI GREEN on review SHA 75e50719** (run 25760223943 - success)

**Note:** Implementation commit 62732701 had CI failure due to CDD artifact validator expecting "CDD Trace" section name but file contains "CDD-Trace" (with hyphen). This is a validator formatting issue, not an implementation problem. The section content is present and complete.

## Regressions Required (D-level only)

N/A — No D-level findings

## Notes

**Quality assessment:** Excellent minimal fix. The implementation is:
- Precisely scoped to the identified gap
- Follows established patterns in the codebase
- Includes appropriate test coverage
- Makes no architectural changes beyond the stated requirement

**Evidence depth:** Adequate. The change adds one string to a list and updates the corresponding test fixture. The `presentPaths()` function correctly handles existence checking, so the behavior is deterministic and testable.

**Search space closure:** Complete review found no remaining blockers. All issue ACs are met, implementation is locally correct, no authority conflicts exist, and all relevant surfaces have been updated appropriately for this scope.
