-# EANCH-WP-0003 — Non-PDF Selectors (HTML / Markdown)
-
-## Goal
-
-Extend anchoring beyond PDFs to non-paginated documents (HTML, Markdown),
-delivering the `DomRangeSelector` and `StructuralSelector` concepts that
-`INTENT.md` names but the MVP left as `never`. The extracted package already
-models format-neutral resolution (`DocumentViewerAdapter`, canonical-text
-selectors); this workplan fills in the DOM branch of `SelectionCapture` and a
-concrete HTML/Markdown viewer adapter.
-
-Depends on the extraction (`EANCH-WP-0001`) being complete. Independent of the
-resolution-hardening track (`EANCH-WP-0002`) except where both touch the shared
-enum — coordinate contract changes in the umbrella wiki first.
-
-## Background
-
-- `src/types.ts`: `DomSelectionCapture = never` (reserved) — the capture union
-  only has a PDF branch today.
-- `citation-engine` shared selector types already declare `DomRangeSelector`
-  and `StructuralSelector` as `never` placeholders; promoting them is a
-  shared-contract change and must land in `citation-engine` first (ADR-0006:
-  selector *types* live in engine).
-
-## Task Breakdown
-
-## T01 — Contract: promote DomRange/Structural selector types in citation-engine
-
-```task
-id: EANCH-WP-0003-T01
-status: done
-priority: high
-state_hub_task_id: "de7df94f-2ddf-4920-949e-6e693131a9de"
-```
-
-Define the real `DomRangeSelector` and `StructuralSelector` shapes (DOM path +
-range offsets; heading/section/block/AST path) in `citation-engine`'s shared
-selector module, plus the `DomSelectionCapture` payload contract in the wiki.
-Land this in the engine + `SharedContracts.md` before writing anchor behavior.
-
-## T02 — Selector creation from a DOM/Markdown selection
-
-```task
-id: EANCH-WP-0003-T02
-status: done
-priority: high
-depends_on: [T01]
-state_hub_task_id: "aa1bc68d-c15a-41e0-813d-c4ccec4914c9"
-```
-
-Implement `createSelectors` for the DOM branch: build TextQuote + TextPosition
-(against canonical text) plus DomRange + Structural selectors from a captured
-DOM selection. Add unit tests mirroring the PDF create tests.
-
-## T03 — Resolution for non-paginated documents
-
-```task
-id: EANCH-WP-0003-T03
-status: done
-priority: high
-depends_on: [T02]
-state_hub_task_id: "2bdedc91-1ed2-41ed-b4a0-a9a0d7a6b4b0"
-```
-
-Extend `resolveSelectors` to resolve DomRange/Structural selectors and rank
-them in the confidence ladder alongside the existing text selectors, keeping
-paginated (PDF) and non-paginated resolution on shared concepts. Tests for
-re-render stability (structural fallback when offsets shift).
-
-## T04 — HTML/Markdown viewer adapter
-
-```task
-id: EANCH-WP-0003-T04
-status: done
-priority: medium
-depends_on: [T03]
-state_hub_task_id: "286267fe-d348-4494-bbe2-dd7818bcadbd"
-```
-
-Add a `DocumentViewerAdapter` implementation for rendered HTML/Markdown
-(selection capture, scroll-to-target, highlight render), behind a subpath
-export analogous to `evidence-anchor/pdf`, with viewer-specific deps confined
-to that boundary.
-
-## T05 — Verification + close-out
-
-```task
-id: EANCH-WP-0003-T05
-status: done
-priority: high
-depends_on: [T04]
-state_hub_task_id: "9ff39c83-eca8-46a1-9b28-8a728ddf220d"
-```
-
-Package green (`pnpm test`/`typecheck`/`lint`); engine contract change verified
-in `citation-engine`; any umbrella consumer green; `fix-consistency` clean;
-progress note.
-
-**Verification (2026-07-09):**
-
-- `citation-engine`: DomRange/Structural types + StructureMap promoted; 89 tests passed.
-- `evidence-anchor`: DOM create/resolve + `evidence-anchor/dom` export; 42 tests passed.
