## Goal Achievement

### Observable Truths (Plan 02-01)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | parse_inf extracts DriverDesc values from a simple INF with literal names | VERIFIED | `test_simple_driver_desc` passes; `parse_inf` returns `["Acme SuperPrint 9000"]` |
| 2 | parse_inf resolves %TOKEN% references via the [Strings] section | VERIFIED | `test_token_resolution` passes; `%HP_DRIVER%` resolves to `"HP LaserJet"` |
| 3 | parse_inf handles UTF-16 LE BOM, UTF-8 BOM, and ANSI (cp1252) encoded INF files | VERIFIED | `test_detect_encoding_utf16le`, `test_detect_encoding_utf16be`, `test_detect_encoding_utf8bom`, `test_detect_encoding_ansi`, `test_utf16_encoding` — all pass |
| 4 | parse_inf deduplicates driver names from multi-model INFs (NTamd64 + undecorated) | VERIFIED | `test_multi_model_inf` passes; `Multi Printer 1000` appears exactly once |
| 5 | parse_inf returns a list of unused files not referenced in the INF text | VERIFIED | `test_unused_files` passes; `readme.txt` in unused_files, `driver.dll` not in unused_files |
| 6 | parse_inf detects architecture from section decorations (x64, x86, arm64) | VERIFIED | `test_architecture_detection_amd64/arm64/undecorated/mixed` — all 4 pass |
| 7 | parse_inf detects presence of .cat file in ZIP member list | VERIFIED | `test_cat_file_detection_present` and `test_cat_file_detection_absent` pass |

### Observable Truths (Plan 02-02)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 8 | User can upload a ZIP file via the /drivers page and receive a success response | VERIFIED | `test_upload_valid_zip` passes; POST /drivers/upload returns 200 |
| 9 | After upload, the response contains a populated select dropdown with driver names from the INF | VERIFIED | `test_upload_returns_select` passes; `<select` and `"Test LaserJet Pro"` in response HTML |
| 10 | Uploading a non-ZIP file or a ZIP with no INF returns a 400 error displayed in-page | VERIFIED | `test_upload_non_zip` and `test_upload_no_inf` both return 400 |
| 11 | Uploaded driver file is persisted to DRIVERS_DIR via DriverStore (survives restart) | VERIFIED | `test_driver_persisted` passes; SHA256-named file exists on disk under tmp_data_dir/drivers/ |
| 12 | Re-uploading the same ZIP does not create a duplicate Driver record (SHA256 dedup) | VERIFIED | `test_dedup_upload` passes; Driver.select().where(sha256==...).count() == 1 after two uploads |
| 13 | Upload response shows count of unused files not referenced by the INF | VERIFIED | `test_unused_files_in_response` passes; word "unused" present in response HTML |
| 14 | GET /drivers renders the drivers page with upload form and existing driver list | VERIFIED | `test_drivers_page` passes; HTML contains `type="file"`, `hx-post`, `/drivers/upload` |

**Score: 14/14 truths verified** (16/16 counting plan artifacts below)

## Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-------------|-------------|--------|----------|
| DRV-01 | 02-02 | User can upload a driver package (ZIP containing INF + supporting files) | SATISFIED | POST /drivers/upload validated; `test_upload_valid_zip` passes |
| DRV-02 | 02-01 | System parses uploaded INF files and extracts valid driver names (DriverDesc) | SATISFIED | `parse_inf` extracts DriverDesc; 16 unit tests all pass |
| DRV-03 | 02-02 | User can select driver name from parsed INF dropdown (no free-text) | SATISFIED | `<select>` dropdown in `driver_list.html`; `test_upload_returns_select` passes |
| DRV-04 | 02-02 | Driver packages are persisted on Docker volume across container restarts | SATISFIED | `DriverStore.save()` writes SHA256-named file to `DRIVERS_DIR`; `test_driver_persisted` verifies file on disk |
| DRV-05 | 02-01, 02-02 | System flags unused files in driver packages to help reduce package size | SATISFIED | `parse_inf` returns `unused_files` list; partial template shows count; `test_unused_files_in_response` passes |

No orphaned requirements. All 5 DRV-0x requirements mapped to plans and verified in codebase.

## Anti-Patterns Found

No blockers or stubs detected.

| File | Pattern | Severity | Impact |
|------|---------|----------|--------|
| `imptune/db/models.py` (indirect) | `datetime.utcnow()` deprecated in Python 3.12+ | Info | DeprecationWarning in test output; does not affect correctness |

The deprecation warning is in the Peewee library's own call path (not in phase 02 code) and carries zero functional risk for the current Python 3.14 runtime target.

## Test Results Summary

| Test Suite | Tests | Passed | Failed |
|-----------|-------|--------|--------|
| `tests/test_inf_parser.py` | 16 | 16 | 0 |
| `tests/test_driver_upload.py` | 8 | 8 | 0 |
| Full suite (`tests/`) | 48 | 48 | 0 |

Zero regressions in pre-existing Phase 1 tests.

## Human Verification Required

### 1. Browser upload flow with HTMX swap

**Test:** Open `/drivers` in a browser, select a real vendor driver ZIP, click Upload.
**Expected:** Page updates in-place (no full reload); driver name appears in a `<select>` dropdown; unused files count shown if any.
**Why human:** HTMX swap behaviour (outerHTML targeting `#driver-list`) and real-vendor INF edge cases cannot be confirmed by automated HTTP tests.

### 2. Duplicate upload visual confirmation

**Test:** Upload the same ZIP twice via the browser.
**Expected:** Driver table shows exactly one row for that driver; no duplicate entry.
**Why human:** The dedup logic is verified by `test_dedup_upload` but the rendered table update on second upload benefits from a visual check.

## Gaps Summary

No gaps. All 14 observable truths verified, all 10 required artifacts present and substantive, all 7 key links wired, all 5 DRV-0x requirements satisfied.
