Progress submissions now carry (percentage, context_text, epubcfi) and the server becomes the position authority: - VerifyProgressAnchor resolves the submitted standard CFI against the book's own XHTML, extracts the text at the anchor, and cross-checks it with the submitted context_text. A mismatch heals the anchor by text search (percentage disambiguates repeats) instead of storing a bad position. - The anchor's block element is derived as a cssSelector plus a block- relative character offset, and served on progress GET alongside the anchor document's href — readium-native handles that let clients re-open a book without parsing CFIs themselves. - context_text-only submissions (no CFI — the dumb-client tier) are anchored structurally from the context text. Motivation: cross-client progress sync (web foliate CFIs, KOReader CRE xpointers, readium-native apps) previously trusted each client's own locator math; the app's EPUB restore drifted ±pages because readium's paginator does not lay out far-from-viewport columns and the foliate- ported CFI walk ran against readium's mutated WebView DOM. Server-side verification heals both classes at ingest.
