## 1. Completeness Check -- Subsystem Catalog

All 8 subsystems are present. Each entry was checked for the required sections:
Location, Responsibility, Key Components, Internal Architecture, Dependencies,
Patterns, Concerns, and Confidence.

| Subsystem | Location | Responsibility | Key Components | Internal Arch | Dependencies | Patterns | Concerns | Confidence | Status |
|-----------|----------|----------------|----------------|---------------|--------------|----------|----------|------------|--------|
| 1. Core DB Layer | OK | OK | OK | OK | OK | OK | OK | OK | PASS |
| 2. Type System | OK | OK | OK | OK | OK | N/A* | OK | OK | PASS |
| 3. Workflow Templates | OK | OK | OK | OK | OK | N/A* | OK | OK | PASS |
| 4. CLI | OK | OK | OK | OK | OK | N/A* | OK | OK | PASS |
| 5. MCP Server | OK | OK | OK | OK | OK | N/A* | OK | OK | PASS |
| 6. Dashboard (API) | OK | OK | OK | OK | OK | N/A* | OK | OK | PASS |
| 7. Dashboard (Frontend) | OK | OK | OK | OK | OK | N/A* | OK | OK | PASS |
| 8. Infrastructure | OK | OK | OK | OK | OK | N/A* | OK | OK | PASS |

*N/A for explicit "Patterns" section: Only Subsystem 1 (Core DB Layer) has a
dedicated "Patterns" section. Subsystems 2-8 integrate pattern descriptions
inline within other sections. This is acceptable -- the information is present
even though it is not consistently sectioned. See NOTE-1 below.

**Result: PASS** -- All 8 subsystems present with all required information.

## 2. Evidence-Based Claims -- LOC Verification

Every LOC claim in the catalog was verified against `wc -l` on the actual source files.

### Core DB Layer
| Claim | Actual | Delta | Verdict |
|-------|--------|-------|---------|
| core.py: 461 LOC | 461 | 0 | EXACT |
| db_base.py: 39 LOC | 39 | 0 | EXACT |
| db_issues.py: 954 LOC | 954 | 0 | EXACT |

| db_schema.py: 281 LOC | 281 | 0 | EXACT |
| db_workflow.py: 250 LOC | 250 | 0 | EXACT |
| **Total: 4,431 LOC** | **4,431** | **0** | **EXACT** |

### Type System
| Claim | Actual | Delta | Verdict |
|-------|--------|-------|---------|
| __init__.py: 163 LOC | 163 | 0 | EXACT |
| core.py: 85 LOC | 85 | 0 | EXACT |
| api.py: 366 LOC | 366 | 0 | EXACT |
| inputs.py: 380 LOC | 380 | 0 | EXACT |
| events.py: 53 LOC | 53 | 0 | EXACT |
| files.py: 119 LOC | 119 | 0 | EXACT |
| planning.py: 91 LOC | 91 | 0 | EXACT |
| workflow.py: 85 LOC | 85 | 0 | EXACT |
| **Total: 1,342 LOC** | **1,342** | **0** | **EXACT** |

### Workflow Templates
| Claim | Actual | Delta | Verdict |
|-------|--------|-------|---------|
| templates.py: 823 LOC | 823 | 0 | EXACT |
| templates_data.py: 1,718 LOC | 1,718 | 0 | EXACT |
| **Total: 2,541 LOC** | **2,541** | **0** | **EXACT** |

### CLI
| Claim | Actual | Delta | Verdict |
|-------|--------|-------|---------|
| cli.py: 35 LOC | 35 | 0 | EXACT |
| cli_common.py: 44 LOC | 44 | 0 | EXACT |
| issues.py: 458 LOC | 458 | 0 | EXACT |
| planning.py: 269 LOC | 269 | 0 | EXACT |
| meta.py: 380 LOC | 380 | 0 | EXACT |
| workflow.py: 378 LOC | 378 | 0 | EXACT |
| admin.py: 522 LOC | 522 | 0 | EXACT |
| server.py: 129 LOC | 129 | 0 | EXACT |
| File count claim: "11 files" | 9 files** | -2 | WARNING |

**The catalog claims "all 11 files read in full (4,757 LOC)" but the actual
file count is: cli.py + cli_common.py + 6 domain modules + __init__.py = 9 files.
The per-file LOC sums to 2,216 (not 4,757). The 4,757 LOC figure likely includes
the cli_commands/__init__.py (1 LOC) but still does not account for the
discrepancy. See FINDING-1.

### MCP Server
| Claim | Actual | Delta | Verdict |
|-------|--------|-------|---------|
| mcp_server.py: 477 LOC | 476 | -1 | MINOR (off-by-one) |
| common.py: 138 LOC | 137 | -1 | MINOR (off-by-one) |
| issues.py: 702 LOC | 701 | -1 | MINOR (off-by-one) |
| files.py: 559 LOC | 558 | -1 | MINOR (off-by-one) |
| meta.py: 531 LOC | 530 | -1 | MINOR (off-by-one) |
| planning.py: 265 LOC | 264 | -1 | MINOR (off-by-one) |
| workflow.py: 381 LOC | 380 | -1 | MINOR (off-by-one) |
| **Total: ~3,050 LOC** | **3,047** | **-3** | **ACCEPTABLE** |

Systematic +1 off-by-one across all MCP files. Suggests the analyst counted
lines including a trailing newline or used a different counting tool. The total
is close and the approximate marker (~) was correctly used.

### Dashboard (API)
| Claim | Actual | Delta | Verdict |
|-------|--------|-------|---------|
| dashboard.py: 454 LOC | 453 | -1 | MINOR |
| common.py: 222 LOC | 221 | -1 | MINOR |
| issues.py: 481 LOC | 481 | 0 | EXACT |

| releases.js: 679 LOC | 679 | 0 | EXACT |
| metrics.js: 223 implied | 223 | 0 | EXACT |
| activity.js: 82 implied | 82 | 0 | EXACT |
| workflow.js: 246 implied | 246 | 0 | EXACT |
| health.js: 259 implied | 259 | 0 | EXACT |
| **Total: ~7,351 LOC** | **7,350** | **-1** | **ACCEPTABLE** |

### Infrastructure
| Claim | Actual | Delta | Verdict |
|-------|--------|-------|---------|
| install.py: 235 LOC | 234 | -1 | MINOR |
| install_support/: 1,086 LOC | 1,083 | -3 | MINOR |
| hooks.py: 406 LOC | 405 | -1 | MINOR |
| ephemeral.py: 291 LOC | 290 | -1 | MINOR |
| server.py: 366 LOC | 365 | -1 | MINOR |
| scanners.py: 223 LOC | 222 | -1 | MINOR |
| migrations.py: 532 LOC | 531 | -1 | MINOR |
| migrate.py: 246 LOC | 245 | -1 | MINOR |
| summary.py: 315 LOC | 314 | -1 | MINOR |
| analytics.py: 198 LOC | 197 | -1 | MINOR |
| validation.py: 34 LOC | 33 | -1 | MINOR |
| logging.py: 73 LOC | 72 | -1 | MINOR |

Same systematic +1 pattern as MCP subsystem. The counting tool used by the
Infrastructure analyst consistently reads 1 line more than `wc -l`.

**LOC Verification Result: PASS** -- All LOC figures are either exact or within
a systematic +1 off-by-one (consistent counting tool difference). No material
misrepresentation. See FINDING-1 for CLI file count.

## 3. Numeric Claims Verification

| Claim (Source) | Actual | Verdict | Notes |
|----------------|--------|---------|-------|
| 83 TypedDict exports (Catalog S2) | 71 names in `__all__` | WARNING | See FINDING-2 |
| 83 TypedDicts (Final Report) | 56 non-input + 46 input = 102 classes | WARNING | See FINDING-2 |
| 42 TypedDicts in api.py (Catalog S2) | 27 class definitions | WARNING | See FINDING-3 |

## 4. Dependency Accuracy

### 4.1 Mixin Composition Order
**Claim:** `FiligreeDB(FilesMixin, IssuesMixin, EventsMixin, WorkflowMixin, MetaMixin, PlanningMixin)`
**Actual:** Confirmed at `core.py:330`. EXACT match.

### 4.2 Cross-Mixin Dependencies (TYPE_CHECKING stubs)
The catalog's cross-mixin dependency diagram was verified against actual
TYPE_CHECKING stubs in each mixin:

| Mixin | Claims deps on | Verified stubs | Match |
|-------|---------------|----------------|-------|
| WorkflowMixin | None (base) | Only TemplateRegistry | OK |
| EventsMixin | WorkflowMixin | `_resolve_status_category`, `_get_states_for_category` | OK |
| MetaMixin | WorkflowMixin, PlanningMixin | `_resolve_status_category`, `_resolve_open_done_states`, `_validate_label_name`, `_validate_parent_id` | PARTIAL* |
| IssuesMixin | Events, Workflow, Meta, Planning | `_record_event` + Template stubs | OK |
| FilesMixin | IssuesMixin | `_generate_unique_id`, `create_issue` | OK |
| PlanningMixin | Events, Workflow, Issues | `_record_event` + Template stubs | OK |

*MetaMixin stubs reference `_validate_label_name` and `_validate_parent_id`,
which appear to come from IssuesMixin rather than PlanningMixin. The catalog's
dependency claim "depends on WorkflowMixin, PlanningMixin" may be incomplete --
it likely also depends on IssuesMixin for those validation stubs. This is a
MINOR accuracy issue in the catalog but does not change the overall architecture
characterization.

### 4.3 Types Zero-Import Constraint
**Claim:** Types modules never import from core/db files.
**Verified:** `grep "from filigree.(core|db_)" src/filigree/types/` returned
NO matches. **CONFIRMED.**

### 4.4 Inbound/Outbound Dependencies
Plausibility assessment:
- Core DB inbound from all interfaces: **Plausible** (verified via imports)
- Types outbound stdlib only: **Confirmed** (grep verification)
- Templates outbound none: **Plausible** (templates_data.py is pure data)
- CLI outbound to Core + Infrastructure: **Plausible** (lazy imports in commands)
- Dashboard mounts MCP via create_mcp_app: **Plausible** (documented pattern)

**Dependency Accuracy Result: PASS** -- All major dependency claims verified or
plausible. One minor inaccuracy in MetaMixin deps (see FINDING-7).

---

## 5. Diagram Accuracy

### 5.1 C4 Level 1 (System Context)
- Three external actors (Developer, AI Agent, Scanner): **Correct**
- Three entry protocols (CLI, MCP, REST POST): **Correct**
- Single SQLite DB: **Correct**

### 5.2 C4 Level 2 (Container Diagram)
- Three interface containers with correct counts: **Correct** (56 CLI, 53 MCP, 4+SPA)
- 6 mixins correctly named and LOC-labeled: **Correct** (all LOC verified above)
- DBMixinProtocol shown as base: **Correct**
- Templates + Type System as separate containers: **Correct**
- Infrastructure tier: **Correct**
- SQLite with WAL/FK/5s timeout: **Correct**

### 5.3 C4 Level 3 (Component Dependency Graph)
- CLI -> MCP, Dashboard, Infrastructure: CLI depends on MCP is **questionable**.
  Actually CLI runs MCP via `main()` indirectly, but primarily depends on Core.
  The arrow from CLI branching to MCP/Dashboard/Infrastructure is slightly
  misleading -- CLI primarily depends on Core, with Dashboard and MCP launched
  as subprocesses. However, the diagram shows all three converging on FiligreeDB
  which is correct. **ACCEPTABLE** simplification.
- Dashboard -> MCP Server (mounts /mcp): **Correct**

### 5.4 Cross-Mixin Dependency Graph
- WorkflowMixin as base with no deps: **Correct**
- EventsMixin/MetaMixin/PlanningMixin as middle tier: **Correct**
- IssuesMixin depending on MetaMixin: **Correct**
- FilesMixin depending on IssuesMixin: **Correct**
- PlanningMixin depending on EventsMixin: **Correct**
- Cross-dependency arrows generally accurate vs TYPE_CHECKING stubs verified above

### 5.5 Data Flow Diagram
- Issue lifecycle through Interface -> Core -> Templates -> SQLite: **Correct**
- Tables listed (issues, events, labels, dependencies, comments): **Correct subset**

### 5.6 Installation Mode Comparison
- Ethereal: PID/port, portalocker, stdio, deterministic port: **Correct**
- Server: server.json, POST /api/reload, HTTP MCP, ContextVar: **Correct**
- Port formula (8400 + hash(path) % 1000): **Plausible** (documented in ephemeral.py)

### 5.7 Frontend Module Architecture
- Module tree with LOC annotations: **Correct** (all verified)
- 9 view modules shown (graph, kanban, detail, files, releases, metrics, activity, health, workflow): **Correct**
- state.js as shared dependency for all views: **Correct**

**Diagram Accuracy Result: PASS** -- All diagrams accurately represent the
subsystem relationships described in the catalog. No material errors.

---

## 6. Report Consistency (Final Report vs Catalog)

### 6.1 Executive Summary Claims
| Claim | Source Agreement | Verdict |
|-------|-----------------|---------|
| ~20K LOC Python | Consistent with coordination doc | OK |
| Hexagonal/ports-adapters | Consistent with catalog layering | OK |
| 6 mixins with Protocol type checking | Catalog S1 confirmed | OK |
| Triple-adapter (CLI, MCP, Dashboard) | All 3 catalog entries present | OK |
| 85%+ test coverage | Discovery doc claim, not verified | UNVERIFIED |

### 6.2 Key Metrics Table
| Metric | Report Value | Catalog/Verification | Match |
|--------|-------------|---------------------|-------|
| Total Python LOC | ~19,600 | Sum of all subsystems: ~18,600+ (excludes tests) | APPROXIMATE |
| Frontend LOC | ~7,350 | 7,350 (verified) | EXACT |
| Test files | 70+ | Not independently counted | UNVERIFIED |
| Subsystems | 8 | 8 catalog entries | EXACT |
| SQLite tables | 10 + FTS5 | 11 + 1 FTS5 | INCONSISTENT (see FINDING-5) |
| MCP tools | 53 | 53 (verified) | EXACT |
| CLI commands | ~56 | 56 (verified) | EXACT |
| Packs | 9 (3 default) | 9 (verified) | EXACT |
| TypedDicts | 83 exported | 71 in __all__ | INCONSISTENT (see FINDING-2) |
| Schema version | 5 | 5 (verified) | EXACT |

### 6.3 Concern Priority Reasonableness

The report organizes concerns into High/Medium/Low tiers. Assessment:

**High Priority (3 items):**
1. Cross-mixin implicit deps -- **Reasonable.** Fragile across refactors, no automated test. Legitimately high risk.
2. Types import constraint unenforced -- **Reasonable.** Single careless import could cause runtime circular import failure. Easy to fix with CI test.
3. Graph v2 loads all issues -- **Reasonable.** Memory/latency concern for large projects. Could be medium if project sizes are bounded.

**Medium Priority (4 items):**
4. db_files.py oversized -- **Reasonable.** At 1,241 LOC it is the largest mixin.
5. Error format divergence -- **Reasonable.** Practical issue for consumers.
6. Title sanitization duplication -- **Reasonable.** DRY violation, easy fix.
7. Hardcoded timeouts -- **Reasonable.** CI/containerization friction.

**Low Priority (3 items):**
8. ~90 window exports -- **Reasonable.** Style concern, not functional.
9. No frontend bundler -- **Reasonable.** Performance concern for production.
10. list.pop(0) BFS -- **Reasonable.** Correctly noted as negligible.

**Concern prioritization is well-calibrated.** No items appear misranked.

### 6.4 Synthesis Quality
The final report accurately synthesizes findings from the catalog. All
architecture strengths are traceable to specific catalog entries. All concerns
map to specific catalog findings. The evolution/maintenance section adds value
beyond the catalog (feature addition workflow, schema evolution, template
evolution). No concerns from the catalog were dropped or misrepresented.

**Report Consistency Result: PASS** -- Report faithfully synthesizes catalog
findings with reasonable editorial judgment on priority.

---

## 7. Coverage Assessment

### 7.1 Subsystem Coverage
All 8 identified subsystems have catalog entries. The subsystem boundaries are
reasonable and cover the full `src/filigree/` directory.

### 7.2 File Coverage Gaps
The coordination doc lists specific files per subsystem. Cross-referencing
against `src/filigree/`:

| File | Subsystem Assignment | Covered |
|------|---------------------|---------|
| `__init__.py` (package root) | Not listed | MINOR GAP |
| `__main__.py` (if exists) | Not checked | N/A |
| `py.typed` marker | Mentioned in discovery | OK |

No significant source files appear to be missing from the analysis.

### 7.3 Test Coverage
Test organization is documented in `01-discovery-findings.md` with a directory
tree. Individual test files were not analyzed (reasonable scope choice).

**Coverage Result: PASS** -- All significant source analyzed.

---

## Findings Summary

### FINDING-1 (WARNING -- Non-blocking): CLI File Count and LOC Discrepancy
The CLI catalog entry claims "all 11 files read in full (4,757 LOC)" but only 9
files exist (cli.py, cli_common.py, __init__.py, + 6 domain modules). The
per-file LOC sums to only 2,216. The "4,757 LOC" figure and "11 files" count
do not reconcile with the filesystem.

Possible explanation: The analyst may have counted `__init__.py` files in
`cli_commands/` and been counting lines from a different tool, or included
additional files like test helpers. However, the per-file LOC figures within
the catalog entry (35 + 44 + 458 + 269 + 380 + 378 + 522 + 129 = 2,215) do
not sum to 4,757 either. The correct total of the listed files is approximately
2,216 LOC across 8 non-trivial files.

**Impact:** Misleading total LOC and file count. Individual per-file LOC values
are all verified correct.

### FINDING-2 (WARNING -- Non-blocking): TypedDict Count Inconsistency
Multiple documents claim "83 TypedDicts" or "83 exported TypedDicts." Actual
counts:
- `__all__` in `types/__init__.py`: 71 names (includes non-TypedDict exports
  like `ISOTimestamp` NewType)
- `class...TypedDict` definitions: 56 non-input + 46 input = 102 total
- Neither 71 nor 102 equals 83

The "83" figure appears to be an intermediate count that is no longer accurate.
This number appears in both the catalog (Subsystem 2) and the final report.

**Impact:** Mildly misleading metric. The actual number of TypedDicts is higher
(102 class definitions) and the exported API surface is 71 names.

### FINDING-3 (WARNING -- Non-blocking): api.py TypedDict Count
Catalog S2 claims "42 MCP/dashboard response TypedDicts" in api.py. Actual
class definitions with TypedDict: 27.

**Impact:** Overstated by 15. May have counted total types including re-exports
or counted differently.

### FINDING-4 (WARNING -- Non-blocking): inputs.py TypedDict Count
Catalog S2 claims "37 MCP tool argument TypedDicts" in inputs.py. Actual class
definitions with TypedDict: 46.

**Impact:** Understated by 9. The actual count is higher than claimed.

### FINDING-5 (WARNING -- Non-blocking): Table Count
Multiple documents claim "10 tables + FTS5." The actual schema defines 11
regular tables + 1 FTS5 virtual table = 12 total:
1. issues, 2. dependencies, 3. events, 4. comments, 5. labels,
6. type_templates, 7. packs, 8. file_records, 9. scan_findings,
10. file_associations, 11. file_events, + issues_fts (FTS5)

**Impact:** Understated by 1 regular table. The file-related tables
(file_records, scan_findings, file_associations, file_events) total 4, which
may have been miscounted as 3.

### FINDING-6 (MINOR): Frontend View Count
Catalog S7 references "8 views" but the frontend module diagram shows 9 view
files (graph, kanban, detail, files, releases, metrics, activity, health,
workflow). The "8 views" may refer to the 8 user-visible view tabs rather
than the 9 JS module files.

**Impact:** Negligible. Ambiguity between view tabs and module files.

### FINDING-7 (MINOR): MetaMixin Dependency Incomplete
Catalog S1 states MetaMixin "depends on WorkflowMixin, PlanningMixin" but the
TYPE_CHECKING stubs also reference `_validate_label_name` and
`_validate_parent_id` which appear to come from IssuesMixin.

**Impact:** Minor incompleteness in the cross-mixin dependency mapping.

---

## NOTE-1: Structural Consistency

The "Patterns" section is explicitly present only in Subsystem 1 (Core DB Layer).
Subsystems 2-8 weave pattern descriptions into Internal Architecture and other
sections. This is acceptable but reduces scanability. A consistent template
would improve the catalog's utility as a reference document.

---

## Confidence Assessment

| Dimension | Level | Basis |
|-----------|-------|-------|
| Structural completeness | High | All 8 subsystems present with all required information |
| LOC accuracy | High | 100% of per-file LOC verified; systematic +1 in 2 subsystems |
| Dependency accuracy | High | Mixin composition and import constraints verified via source |
| Diagram accuracy | High | All 7 diagrams cross-checked against catalog and source |
| Report synthesis | High | Concerns faithfully reflected, priorities reasonable |
| Numeric claims | Medium | Several counts (TypedDicts, tables) do not match source |

---

## Risk Assessment

| Risk | Severity | Mitigation |
|------|----------|------------|
| TypedDict count cited in downstream work | Low | The "83" figure is not architecturally significant |
| Table count error in schema planning | Low | Off by 1, easily corrected |
| CLI LOC total misleading | Low | Per-file figures are correct; only totals wrong |
| Cross-mixin dep incomplete for MetaMixin | Low | Does not change architecture characterization |

---

## Information Gaps

1. **Test coverage distribution** -- Claimed 85%+ but not verified per-subsystem
2. **Runtime performance** -- Explicitly noted as a gap in the report
3. **CI pipeline** -- Not reviewed (noted in report)
4. **Production usage patterns** -- Not available (noted in report)

These gaps are all explicitly acknowledged in the final report's "Known gaps"
section, which is proper practice.

---

## Caveats

1. This validation checks **structural correctness** (LOC, file counts, section
   presence, cross-document consistency). It does NOT validate **technical
   accuracy** of architectural insights, pattern identification quality, or
   concern completeness. Those require domain expertise beyond structural
   validation.

2. LOC counts were verified using `wc -l` which counts physical lines including
   blanks and comments. The systematic +1 discrepancy in some subsystems may
   reflect a different counting method used by those subagents.

3. The TypedDict counting discrepancy (FINDING-2 through FINDING-4) may reflect
   the analysts using a different definition of "TypedDict" (e.g., counting
   base + derived separately, or counting re-exports).

---

## Verdict

**PASS_WITH_NOTES**

The architecture analysis is structurally sound, comprehensive, and internally
consistent. All 8 subsystems are thoroughly documented with evidence-based claims.
LOC figures are verified accurate at the per-file level. Diagrams faithfully
represent the catalog's architectural description. The final report accurately
synthesizes catalog findings with well-calibrated concern priorities.

The findings above (primarily numeric count discrepancies) are non-blocking
documentation errors that should be corrected in a revision pass but do not
undermine the analysis's utility or accuracy for architectural decision-making.

**No critical issues. No blocking issues. Safe to use as architectural reference.**

### Recommended Corrections (Optional)
1. Fix TypedDict count: replace "83" with actual verified number in catalog and report
2. Fix table count: "11 tables + 1 FTS5 virtual table" (not "10 + FTS5")
3. Fix CLI file count and LOC total in catalog entry confidence statement
4. Fix api.py TypedDict count (27, not 42) and inputs.py count (46, not 37)
5. Add MetaMixin -> IssuesMixin dependency to the cross-mixin dependency listing
6. Consider standardizing the "Patterns" section across all catalog entries
