 - **Sponsor placeholder copy in `IPDetailPage`** — `data-testid="sponsor-report-panel"` placeholder points the Sponsor to "the top navigation Report tab." The wording "top navigation" is generic; if the V1 6-tab nav lands a localized label, the placeholder should reference the actual tab label.

+### 2026-05-17: Survey-rule layer still emits 'handoff' surface prompts
+
+`packages/core/src/survey/handoff.ts:69` produces `surveyInboxRules` entries with `surface: 'handoff'`, which now route through the `showHandoff → showSustainment` alias in panelsStore. Wedge V1 (PR-WV1-4) retired the canvas-CTA handoff path; the survey rule layer is intentionally out-of-scope per ADR-082. **Follow-up**: in a later wedge cleanup PR, retire the survey rule too (or rename to `surface: 'sustainment'` + reword the prompt text). Source: Opus review of PR #187 (2026-05-17).
+
+**Surfaced by:** Opus final code review of PR #187 (feat/wedge-pr-wv1-4-canvas-persona), 2026-05-17.
+
+**Promotion path:** Wedge cleanup PR post-V1 stabilisation — rename `surface: 'handoff'` → `surface: 'sustainment'` and reword prompt copy, or retire the rule entirely if the survey cadence no longer fits the Sustainment stage flow.
