+# Phase 7 Plan 00: Wave 0 TDD Stubs — VALID-01 and UX-01 Summary
+
+**12 failing test stubs for regex format validation (Azure/S3/GCS) and ⓘ tooltip toggle (sas_url/SFTP/OneDrive) establish TDD RED state for Phase 7 implementation**
+
+## Performance
+
+- **Duration:** ~10 min
+- **Started:** 2026-03-31T09:40:00Z
+- **Completed:** 2026-03-31T09:48:00Z
+- **Tasks:** 1
+- **Files modified:** 1
+
+## Accomplishments
+
+- Added `describe('VALID-01 — format validation')` block with 7 tests: Azure account name reject/accept, S3 region reject/accept, GCS project_number reject/accept
+- Added `describe('UX-01 — contextual tooltips')` block with 5 tests: ⓘ button presence on azureblob sas_url, show tooltip on click, hide on second click, ⓘ on SFTP auth section, ⓘ on OneDrive token field
+- 9 tests fail with clear assertion errors (RED state confirmed), 3 acceptance tests pass correctly
+- All 147 pre-existing tests still pass — zero regressions
+
+## Task Commits
+
+1. **Task 1: Add failing VALID-01 and UX-01 test stubs** - `327421e` (test)
+
+**Plan metadata:** (docs commit follows)
+
+## Files Created/Modified
+
+- `src/components/wizard/RemoteConfigStep.test.tsx` - Added 12 new test cases in two describe blocks (VALID-01 and UX-01); 172 lines added; imports extended with `describe, it, expect`
+
+## Decisions Made
+
+- Removed `vi.useFakeTimers()` from new describe blocks: fake timers combined with `userEvent.setup()` cause `waitFor` to deadlock when testing form submissions (async React state updates never settle). The existing 21 tests work without fake timers — the same pattern applies here.
+- Acceptance tests ("accepts valid X") are naturally green before implementation and serve as regression guards post-implementation. The 11-failures target in the plan was aspirational; 9 clean failures correctly establishes RED state.
+- UX-01 button-presence tests assert via `getByRole` directly (no `waitFor`) so they fail immediately with "Unable to find role 'button'" — clear, fast failure signal.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Removed vi.useFakeTimers() from new test blocks**
+- **Found during:** Task 1 (running stubs for first time)
+- **Issue:** Initial stubs used `vi.useFakeTimers()` + `userEvent.setup({ advanceTimers })` pattern from research notes. This caused all 12 new tests to time out at 5s instead of failing fast — fake timers freeze the event loop, so `waitFor` never resolves.
+- **Fix:** Removed `vi.useFakeTimers()` / `vi.useRealTimers()` / `beforeEach` / `afterEach` from both describe blocks. Used plain `userEvent.setup()` matching the pattern of the existing 21 tests.
+- **Files modified:** src/components/wizard/RemoteConfigStep.test.tsx
+- **Verification:** Re-run confirmed 9 failures with clear assertion errors (not timeouts), 150 passing
+- **Committed in:** 327421e (Task 1 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (Rule 1 - Bug: fake timers deadlock)
+**Impact on plan:** Fix essential for RED state to be meaningful. Tests now fail with clear errors pointing to the missing features, not cryptic timeouts.
+
+## Issues Encountered
+
+- Fake timers + userEvent.setup() interaction: The research notes mentioned `vi.useFakeTimers()` as a pattern from Phase 5/6, but those tests suppressed `setTimeout` act() warnings in render-only tests, not form-submission tests. Form submission tests use `userEvent.click()` which fires async events — fake timers prevent these from propagating. Real timers are correct here.
+
+## Next Phase Readiness
+
+- Plan 07-01 (VALID-01 implementation) has clear targets: 4 VALID-01 reject tests must turn green by adding `validate?` to `FieldDef`, extending `buildZodSchema()` with `.regex()`, and adding validate rules to 3 registry entries
+- Plan 07-02 (UX-01 implementation) has clear targets: all 5 UX-01 tests must turn green by adding `tooltipText?` to `FieldDef`, adding ⓘ button + toggle to FieldRenderer/PasswordField, and adding SftpAuthToggle standalone tooltip
+- No blockers — codebase is stable, test infrastructure confirmed working
