Derived 6 rows: one per DRV-0x success criterion from v1.0-ROADMAP.md Phase 2 (DRV-01..05 = rows 1-5), plus row 6 for the mandatory POST /drivers/upload 500 historical gap per CONTEXT.md locked decision.
Row 6 resolved PASS (not fail-fix-v1.1) because Phase 9 Plan 01 UX-01 was already Complete in REQUIREMENTS.md at audit time — the plan explicitly permits this closure pattern. Cited fixing commits d1de839 (RED tests), 10ee09a (handler fix), 72c6a98 (printer_form wiring).
nyquist_compliant flipped to true because all 6 rows are pass; no deferred/wont-do/fail rows.
Cross-referenced all 5 DRV-0x criteria against 02-VERIFICATION.md's 14 observable truths (14/14 verified 2026-04-10) to keep evidence traceable to the original verifier run.

Phase 08 Plan 02: Phase 2 Nyquist Audit Summary
One-liner: Audited Phase 2 (Driver Management, DRV-01..05) against Nyquist rules and upgraded 02-VALIDATION.md in place with a 6-row Nyquist Record where every DRV-0x success criterion maps to exactly one observable pytest check, plus a formal row closing the Phase 8 kickoff-surfaced POST /drivers/upload HTTP 500 historical gap via Phase 9 / UX-01 fixing commits.
What Shipped
.planning/phases/02-driver-management/02-VALIDATION.md now contains a ## Nyquist Record section (placed above Validation Sign-Off, below Manual-Only Verifications).
6 rows: one per DRV-0x success criterion (5) + one historical-gap closure row for the POST /drivers/upload 500 defect.
Every row has a non-empty Observable Check cell (pytest invocation) and a non-empty Evidence cell citing committed tests, source paths, commit SHAs, and the dated 02-VERIFICATION.md run.
Row 6 formally records the POST /drivers/upload 500 defect reported 2026-04-13 during Phase 8 kickoff, links it to Phase 9 / UX-01, and closes it as pass citing the fixing commits d1de839 (RED tests), 10ee09a (handler caller-branch fix), and 72c6a98 (printer_form.html wiring).
Frontmatter updated: nyquist_compliant: false → true, added nyquist_audited: 2026-04-13, nyquist_auditor: Claude (gsd-executor, plan 08-02).
Phase 2 is Nyquist-compliant. Zero gaps carry forward into 08-08 (rollup). The POST /drivers/upload 500 is recorded as a historical-gap row resolved in Phase 9.
Evidence Strategy Used
Priority order from CONTEXT.md was honored:
Test evidence (preferred): used for all 6 rows — tests/test_driver_upload.py (test_upload_valid_zip, test_upload_non_zip, test_upload_no_inf, test_drivers_page, test_upload_returns_select, test_driver_persisted, test_dedup_upload, test_unused_files_in_response, test_upload_500_regression, test_upload_oob_*) and tests/test_inf_parser.py (16 tests).
Dated manual-check evidence: 02-VERIFICATION.md (2026-04-10, 14/14 observable truths verified) referenced in Notes columns for cross-traceability.
No row relied on "code looks right" — every check is an actual pytest invocation.
Cross-Reference with 02-VERIFICATION.md
02-VERIFICATION.md (dated 2026-04-10) already enumerated 14 observable truths split across plans 02-01 (7 truths on the INF parser) and 02-02 (7 truths on the upload endpoint + UI). The Nyquist Record maps:
This keeps the two documents 1:1 alignable for rows 1-5.
Deviations from Plan
None. Plan 08-02 executed exactly as written. Single task, single file edit.
Minor interpretive choice (within plan latitude, step 6 explicitly allowing this): row 6 was recorded as pass citing Phase 9 UX-01 fixing commits rather than fail-fix-v1.1. The plan's Task 1 step 6 anticipates this exact case — "if UX-01 is complete, cite the fixing commit and flip status accordingly". UX-01 is marked Complete in REQUIREMENTS.md, so the historical gap is recorded in the Notes column but closed as pass. Same precedent established in 08-01 row 14 (Phase 1 spike → Phase 10 RTVAL-01 close).
Authentication Gates
None.
