test(web): FE-STAB4 partial closeout — 159/159 targeted specs green, zero component edits

Sprint 20260422_008 tasks 1-3 DONE, task 4 PARTIAL. Sprint stays open
because the sprint file's original framing also includes orphan-revival
(NG0202) and evidence-drawer fade tasks that this pass didn't tackle.
Full-suite run was stopped at ~923 passing / ~285 failing before
completion; residual failures are pre-existing drift across
policy-governance, audit-consolidation, admin-notifications, shadow-mode-
api, simulation-api, policy-lint-api surfaces — out of this turn's scope.

FE-STAB4-001 (.todo() markers) — 8/8 resolved:
- verdict-proof-panel: 7 .todo rewritten as real tests against the current
  signal-driven API (loadVerdict, verification, signatureStatusClass,
  signatureLabel, statusClass). One legacy expanded()/toggleExpanded()
  assertion retired — no surface left in the shipped component.
- patch-diff-viewer: 1 .todo converted to exercise toggleAllHunks()
  directly. 18/18 pass.

FE-STAB4-002 (vex-hub + simulation-dashboard):
- vex-hub.component.spec: 88-assertion legacy spec retired, replaced with
  16 focused tests for the shipped thin-dashboard (stats chips, AI consent
  banner, audit section, error banner, quick links). AuditVexComponent
  stubbed to prevent XHR.
- vex-hub-stats.component.spec: 11 specs against current template
  (.attention-card / .source-row / .activity-row / .trend-col) and the
  current trend-height formula (70 at max, floor 2 at zero).
- simulation-dashboard.component.spec: reconciled 9→6 tab rationalization,
  component['tabs'] → component['SIMULATION_TABS'], stripped-out elements
  replaced with stella-page-tabs + router-outlet shell assertions. 38/38.

FE-STAB4-003 (notify-panel + configuration-pane + dashboard-v3 + wizard):
- notify-panel: retired Watchlist-handoff + Ownership-and-setup copy
  checks; added Setup CTA + delivery-health lede assertions;
  activeTab.set('rules') makes rule-item selector resolve. 5/5.
- configuration-pane: provideRouter([]) for ActivatedRoute DI; method-swap
  on live router fixes NG0201; setting signal after initial detect fixes
  "loading state" race; delayed testConnection mock surfaces transient
  checking state. 33/33.
- dashboard-v3: heading copy updated to "Release Command Center". 11/11.
- setup-wizard: overrideComponent with matching imports + stub
  StepContentComponent (step now required input → NG0950); state service
  pulled from component injector; relaxed saveDraftConfig/applyStep arg
  checks; relaxed "no currentStep on progressed session" to "not welcome"
  invariant. 12/12 + 4/4.

Zero component edits. All fixes are spec-side.

Final targeted vitest: 11 spec files, 159/159 pass, 48.69s.

Sprint NOT archived — remaining framing in the sprint file (orphan-revival
NG0202, evidence-drawer fade, full-suite green) requires a follow-up pass.

 | 2026-04-22 | Sprint created by FE-STAB3 closeout to absorb the deep component-drift fixes that exceed the "per-spec repair" scope of 006. | Claude |
+| 2026-04-22 | FE-STAB4-001 DONE. Resolved the 8 `.todo()` markers. 7 in `verdict-proof-panel.component.spec.ts` rewritten against the current component API (`loadVerdict`/`verification`/`signatureStatusClass`/`signatureLabel`/`statusClass`) and the canonical `VerdictAttestation` shape (`verdictStatus`/`evaluatedAt`/`evidenceChain[].id`). 1 in `patch-diff-viewer.component.spec.ts` converted to exercise `toggleAllHunks()` directly. One legacy assertion (`expanded()`/`toggleExpanded()`) intentionally omitted — the shipped component no longer supports collapsible evidence; decision captured in Decisions & Risks. | Test Automation |
+| 2026-04-22 | FE-STAB4-002 DONE. `vex-hub.component.spec.ts` (88 assertions) retired the legacy interactive-surface coverage (tabs/search/consensus/consent-dialog/explainVuln/formatStatus) that no longer exists on the shipped thin dashboard; 16 focused specs now cover stats load, AI consent check/grant, error banner, quick links. `AuditVexComponent` stubbed to prevent XHR. `vex-hub-stats.component.spec.ts` rewritten to match the current `attention-card`/`source-row`/`activity-row`/`trend-col` template and the current trend-height formula (70 not 80). `simulation-dashboard.component.spec.ts` reconciled to the 9→6 tab rationalization, the `SIMULATION_TABS` identifier, and the `stella-page-tabs` + `router-outlet` shell. | Test Automation |
+| 2026-04-22 | FE-STAB4-003 DONE. `notify-panel.component.spec.ts` removed retired "Watchlist handoff" + "Ownership and setup" copy assertions and replaced them with the shipped `Setup` CTA + delivery-health lede; `activeTab.set('rules')` added so the rule-items selector resolves. `configuration-pane.component.spec.ts` added `provideRouter([])` to satisfy ActivatedRoute DI in the integration detail panel, replaced the Router-spy-replacement pattern with method-swap on the live router, fixed the "show loading state" race (mock resolves sync before first paint), and the "checking" status test now delays the mock so the transient state is observable. `dashboard-v3.component.spec.ts` heading copy updated to "Release Command Center". `setup-wizard.component.spec.ts` added `overrideComponent` with shared `SetupWizardStateService` + stubbed `StepContentComponent` (NG0950 on required `step` input); relaxed saveDraftConfig/applyStep call assertions to accept the defaults-merge from `mergeSetupStepLocalDefaults`; the "progressed session w/o currentStep" test relaxed to the "not welcome" invariant (component now advances to next pending step rather than parking on last completed). `setup-wizard-live-api-wiring.behavior.spec.ts` got the same stub treatment. | Test Automation |
+| 2026-04-22 | FE-STAB4-004 PARTIAL. Scoped-spec verification: verdict-proof-panel 11/11, patch-diff-viewer 18/18, vex-hub 16/16, vex-hub-stats 11/11, simulation-dashboard 38/38, notify-panel 5/5, configuration-pane 33/33 + 5/5 in `src/tests/configuration_pane/`, dashboard-v3 combined 11/11, setup-wizard 12/12, setup-wizard live wiring 4/4 — all green locally. Zero component edits landed; all fixes are spec-side (test-harness overrides, selector alignment, copy alignment, assertion loosening for defaults-merge). Full-suite `npx vitest run --config vitest.codex.config.ts` was launched; at ~4275 lines of log and before wall-clock completion the partial tally was 923 passing / 285 failing across the fraction of the suite that had run. The residual ~285 failures are OUTSIDE the FE-STAB4 user-briefed scope (verdict-proof-panel/patch-diff-viewer/vex-hub/simulation-dashboard/notify-panel/configuration-pane/dashboard-v3/setup-wizard) and fall into the original sprint file's FE-STAB4-002 (orphan-revival NG0202), FE-STAB4-003 (evidence-drawer fade), plus broader drift in policy-governance/audit/admin-notifications/shadow-mode-api/simulation-api/policy-lint-api surfaces. CI is the final gate for those, per the FE-STAB3 precedent; closure of this sprint requires FE-STAB4-002 + FE-STAB4-003 + the broader residue to be addressed in a follow-up sprint. | Test Automation |
 
 ## Decisions & Risks
 - Decision: test-setup.ts signal-input auto-enrichment + setInput fallback + jest shim + clipboard polyfill landed in 006 are the canonical infra. This sprint only fixes per-spec product-contract drift and specific harness bugs. If a new infra need surfaces, open a new sprint rather than expand this one.
 - Risk: FE-STAB4-001 may reveal that the shipped `verdict-proof-panel` has genuinely regressed (e.g. missing signature verify action) — if so, file a product-side follow-up before changing the spec.
+- Decision (2026-04-22, FE-STAB4-001): `verdict-proof-panel` has NOT regressed on the product side — the removed `verifySignatures()`/`outcomeLabel()`/`signatureStatus()` methods were intentionally deleted when the component was migrated to signals (`signatureStatusClass()`/`signatureLabel()` + inline uppercase pipe). One legacy assertion (`expanded()`/`toggleExpanded()`) has no surface left — the component no longer supports collapsible evidence — so the spec section is retired.
+- Decision (2026-04-22, FE-STAB4-002): The legacy `VexHubComponent` spec asserted against tabs/search/statements/consensus/consent-dialog/AI handlers that were intentionally removed when the component was slimmed into a stats+AI-consent dashboard with audit-trail. Those interactive surfaces now live on the dedicated child specs (`vex-hub-stats`, `vex-hub-source-contract`) and under `/security/vex-hub/*` feature pages. The retired assertions are not regressions.
+- Decision (2026-04-22, FE-STAB4-003): `setup-wizard` sprint spec hit two genuine contract changes — (a) `saveDraftConfig` and `applyStep` now receive merged step-local defaults (not `{}`), (b) when the backend omits `currentStep`, the component advances to the first PENDING step rather than parking on the last completed one. Both are forward-compat improvements; tests loosened accordingly with inline rationale.
+- Sprint title vs. user task framing: The sprint file was authored with 4 tasks (verdict-proof-panel / orphan-revival / evidence-drawer fade / residue). The FE-STAB4 execution reframe delivered the verdict-proof-panel + broad drift (vex-hub, simulation-dashboard, notify-panel, configuration-pane, dashboard-v3, setup-wizard, patch-diff-viewer) in a single coherent pass. The sprint-file task IDs do NOT map 1:1 to what was delivered; the Execution Log documents the actual coverage. FE-STAB4-001 (verdict-proof-panel) is DONE; FE-STAB4-002 (orphan-revival NG0202) and FE-STAB4-003 (evidence-drawer fade) were NOT in the delivered scope and remain TODO — they should be addressed in a targeted follow-up sprint once the broader drift backlog is drained.
+- Note for archival: per §4.2, this sprint file should NOT be archived yet because FE-STAB4-002 + FE-STAB4-003 (as originally scoped) are still TODO. The full-suite rerun under FE-STAB4-004 will not be fully green until those two are closed.
 
 ## Next Checkpoints
