-# Phase 3 plan-phase preferences (captured pre-UI-SPEC exit)
-
-User invoked `/gsd-plan-phase 3` 2026-05-20 and answered both initial gate
-questions before workflow exited at UI-SPEC gate. These preferences should be
-re-honored on next `/gsd-plan-phase 3` invocation (after `/gsd-ui-phase 3`
-completes):
-
-## UI Design Contract gate
-
-**Decision:** Generate UI-SPEC.md first → run `/gsd-ui-phase 3` before
-re-running plan-phase.
-
-**Caveat to revisit:** Phase 3 is verification-only — the "page" keyword that
-tripped the gate refers to Puppeteer test fixture pages (synthetic HTML for
-rrweb DOM probing), not user-facing UI. /gsd-ui-phase may produce a thin
-UI-SPEC.md or recommend skipping. Either is acceptable. If it surfaces an
-"is this a UI phase?" question, answer "no — internal test fixtures only".
-
-## Research gate
-
-**Decision:** Research first (light) → spawn gsd-phase-researcher before
-planning.
-
-**Scope for researcher:** light investigation of
-- `puppeteer.Page.metrics()` API for optional RAM scaffolding (D-P3-04)
-- Any new rrweb 2.0.0-alpha.4 testing patterns relevant to DOM verification
-- Verification of alpha-pin safety vs stable v2 ship status (informational —
-  upgrade itself is deferred to Phase 4 per D-P3-03)
-
-Researcher should NOT investigate:
-- rrweb v2 upgrade implementation path (deferred to Phase 4)
-- Full rrweb maskInputFn or data-sensitive masking (out of scope v1 per
-  charter shift)
-- Programmatic RAM measurement via chrome.devtools Memory API (deferred)
-
-## Auto-cleanup
-
-Delete this file when /gsd-plan-phase 3 successfully completes planner
-spawn (after honoring these preferences).

+## Open Questions (RESOLVED)
 
 1. **Wave structure: parallel or sequential for Plans 03-01..04?**
    - What we know: Plan 02-04 ran A24-A28 sequentially within a single plan (one author). Phase 3's 5-plan structure is finer-grained per D-P3-01.
