Plan 01-01 (Wave-0 doc cascade) complete. Six tasks landed atomically
in commits 125c032, fb88830, b1ed2cb, 597d967, 32bc996, 4a5194e. Every
code-touching plan in Phase 1 (01-02..01-07) now reads a consistent
baseline: getDisplayMedia replaces tabCapture in DEC-003; long-lived
port replaces alarms in DEC-010; manifest.json carries the final
Phase-1 permissions set (desktopCapture, activeTab, downloads,
scripting, storage, offscreen).
SUMMARY: .planning/phases/01-stabilize-video-pipeline/01-01-SUMMARY.md
Replace the REQ-video-ring-buffer bullet to bind the new
getDisplayMedia + offscreen-document acquisition path and drop the
'active-tab' wording (the new API is screen/window-scoped, not
tab-scoped, so there is nothing to re-attach on tab switch). Encoding,
buffer window, and SPEC §10 acceptance citations are unchanged. Adds
CON-display-capture-binding alongside the existing constraint bindings.
