Task 1 Report: Cached OUI Identity Resolution

Status

Implemented and verified cached local OUI identity resolution while preserving the existing oui_vendor() behavior and unrelated unstaged HTML report changes.

Checklist

• Added failing resolver tests before production changes.
• Verified the tests failed because OUI_DATA_PATHS and oui_identity() were absent.
• Added Nmap and macchanger data paths.
• Added a lazy process-level identity cache.
• Added local database parsing for plain and separated OUI prefixes.
• Preserved Nmap precedence over macchanger and built-in fallback.
• Added local/randomized and unknown identities.
• Returned JSON-safe dictionaries with manufacturer, model, oui, and source.
• Kept model as None for every source.
• Preserved oui_vendor() behavior.
• Ran focused and regression tests.
• Self-reviewed the diff and checked whitespace.

TDD Evidence

Initial command:

python3 -m unittest tests.test_recon.OuiVendorTest -v

Initial result before implementation:

Ran 8 tests in 0.005s

FAILED (errors=3)

All three new identity tests errored at mock.patch.object(server, 'OUI_DATA_PATHS', ...) with:

AttributeError: <module 'server' ...> does not have the attribute 'OUI_DATA_PATHS'

After the minimal implementation, the focused resolver test result was:

python3 -m unittest tests.test_recon.OuiVendorTest -v

Ran 9 tests in 0.005s

OK

Final Verification

Command:

python3 -m unittest tests.test_recon.DecodersTest -v

Output:

test_decode_encryption_cases (tests.test_recon.DecodersTest.test_decode_encryption_cases) ... ok
test_decode_ssid_bytes_and_str (tests.test_recon.DecodersTest.test_decode_ssid_bytes_and_str) ... ok
test_decode_ssid_cli_escapes (tests.test_recon.DecodersTest.test_decode_ssid_cli_escapes) ... ok
test_fmt_mac_colon_form (tests.test_recon.DecodersTest.test_fmt_mac_colon_form) ... ok
test_fmt_mac_noop (tests.test_recon.DecodersTest.test_fmt_mac_noop) ... ok
test_norm_mac_12hex (tests.test_recon.DecodersTest.test_norm_mac_12hex) ... ok

----------------------------------------------------------------------
Ran 6 tests in 0.005s

OK

Command:

python3 -m unittest tests.test_recon -v

Output summary:

----------------------------------------------------------------------
Ran 119 tests in 0.681s

OK

All 119 individual tests printed ... ok; there were no failures, errors, or warnings.

Command:

git diff --check

Output: no output; exit status 0.

Self-Review

• Local/randomized detection occurs before cache loading, avoiding unnecessary file access.
• Cache precedence follows path order and never overwrites an earlier prefix.
• Missing files are skipped without masking parsing or programming errors.
• Unknown and invalid MACs return JSON-safe values.
• AA was not used as the unknown global test prefix because its locally administered bit is set; AC correctly represents a globally administered unknown prefix.
• Existing unstaged HTML signal-ordering changes in server.py and tests/test_recon.py are intentionally excluded from the Task 1 commit.

Concerns

None. Database source labels rely on the specified two-entry OUI_DATA_PATHS ordering.

Live Path Correction

The committed Task 1 diff used /usr/share/macchanger/OUI.list, but the design specification and live macchanger package use /usr/share/macchanger/wireless.list. Updated OUI_DATA_PATHS to the required live path. Resolver tests patch OUI_DATA_PATHS, so no test changes were needed.

Verification after the correction:

python3 -m unittest tests.test_recon.OuiVendorTest -v

Ran 9 tests in 0.005s

OK

python3 -m unittest tests.test_recon -v

Ran 119 tests in 0.498s

OK

The unrelated unstaged HTML signal-ordering changes in server.py and tests/test_recon.py, plus untracked loot and certificate files, remain excluded from this correction.
