EANCH-WP-0001 T06: register post-extraction gaps as follow-on workplans

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.

+# EANCH-WP-0002 — Anchor Resolution Hardening
+
+## Goal
+
+Close the resolution-quality gaps left open by the MVP extraction
+(`EANCH-WP-0001`) on the **existing PDF/text path**. The extracted slice
+resolves exact position/quote/PDF selectors with a fixed confidence ladder and
+returns `resolved | ambiguous | unresolved`. `INTENT.md` promises more:
+`stale` detection, orphaned-annotation handling, fuzzy/recovery re-anchoring,
+and human-confirmation workflows for ambiguity. This workplan makes those real
+without changing the shared selector *types* (those stay in `citation-engine`).
+
+Non-goals: HTML/Markdown selectors (see `EANCH-WP-0003`); new persistence or
+UI shell behavior.
+
+## Background
+
+Current extracted behavior (`src/selectors/resolve.ts`):
+
+- confidence ladder 1.00 → 0.70 across TextPosition/TextQuote/PdfPageText/PdfRect
+- multiple undisambiguated quote matches → `ambiguous` at 0.5
+- nothing matches → `unresolved` at 0.0
+- there is **no** `stale` path (the `AnnotationResolutionStatus` enum includes
+  `stale`, but resolve.ts never returns it) and **no** fuzzy matching
+
+## Task Breakdown
+
+## T01 — Stale vs. unresolved: distinguish "representation changed" from "never found"
+
+```task
+id: EANCH-WP-0002-T01
+status: todo
+priority: high
+```
+
+Return `stale` (not `unresolved`) when a previously-resolvable anchor no longer
+matches because the representation's canonical text changed, while the stored
+quote is still meaningful. Define the signal (e.g. position selector points
+in-range but slice ≠ quote AND quote no longer found) and preserve the original
+quote/context on the result. Add unit tests covering stale vs. unresolved.
+
+## T02 — Orphaned-annotation detection surface
+
+```task
+id: EANCH-WP-0002-T02
+status: todo
+priority: medium
+depends_on: [T01]
+```
+
+Give callers a way to identify annotations whose selectors can no longer be
+placed at all (orphaned) versus stale-but-recoverable. Decide whether this is a
+distinct status, a flag on `AnchorResolution`, or a helper. Keep the shared
+enum unchanged unless a contract change is agreed in the umbrella wiki first.
+
+## T03 — Fuzzy / recovery re-anchoring
+
+```task
+id: EANCH-WP-0002-T03
+status: todo
+priority: high
+depends_on: [T01]
+```
+
+Add a fuzzy quote-matching fallback (bounded edit-distance / token overlap)
+below the exact ladder, returning candidates at appropriately low confidence
+with `ambiguous`/`stale` status. Must never silently emit a confident wrong
+match (INTENT: "No Silent Misleading Match"). Add tests with lightly-edited
+source text. Confirm the ladder's exact tiers are untouched above the fuzzy
+floor.
+
+## T04 — Promote the PDF spike to a production adapter
+
+```task
+id: EANCH-WP-0002-T04
+status: todo
+priority: medium
+depends_on: [T03]
+```
+
+Turn `PdfSpikeViewer` into a supported `PDFViewerAdapter` that implements the
+`DocumentViewerAdapter` contract cleanly (remove spike-only debug flags from the
+public surface, or gate them), keep viewer libs behind `src/pdf/`, and keep the
+umbrella green through the change. Update `evidence-anchor/pdf` exports and docs.
+
+## T05 — Verification + close-out
+
+```task
+id: EANCH-WP-0002-T05
+status: todo
+priority: high
+depends_on: [T02, T04]
+```
+
+`pnpm test`/`typecheck`/`lint` green here; umbrella typecheck/test/build green
+after any contract-visible change; `fix-consistency` clean; progress note.

+# 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: todo
+priority: high
+```
+
+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: todo
+priority: high
+depends_on: [T01]
+```
+
+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: todo
+priority: high
+depends_on: [T02]
+```
+
+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: todo
+priority: medium
+depends_on: [T03]
+```
+
+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: todo
+priority: high
