Draft two proposed workplans instead of expanding this slice:
- EANCH-WP-0002 anchor-resolution-hardening (stale/orphan, fuzzy re-anchoring,
promote PdfSpikeViewer to a production PDFViewerAdapter)
- EANCH-WP-0003 non-pdf-selectors (HTML/Markdown DomRange+Structural, non-PDF
viewer adapter; starts with a citation-engine shared-type contract change)
Add an explicit gap map to WP-0001 T06. fix-consistency (C-06) will register
both in the hub during T07.
