# EANCH-WP-0001 — Bootstrap And Extract Evidence Anchor
## Goal
Turn `evidence-anchor` from an intent-only placeholder into the real home of
the current anchor slice that already exists in
`../citation-evidence/src/anchor/`, while keeping the extraction bounded enough
to run safely under `/ralph-workplan`.
This workplan is intentionally about **package bootstrap + code extraction +
consumer cutover + verification**. It is not the place to invent the full next
generation of anchor behavior.
## Ralph Loop Fit
Recommended invocation once the repo is ready to execute:
```text
/ralph-workplan workplans/EANCH-WP-0001-intent-placeholder.md --max-iterations 12
```
Guardrails for the loop:
- stop at extraction/cutover/verification; do not expand into open-ended
feature design during the same loop
- if stale detection, fuzzy recovery, or HTML/Markdown support turns into
substantive new implementation work, register a follow-on workplan instead of
growing this one in place
- HEUREKA condition for this workplan is: extracted package exists, umbrella
consumer is wired to it, verification is green, and the remaining gaps are
registered as next work rather than left implicit
## Background And References
Repo review on 2026-07-08 found that `evidence-anchor` is still docs-only:
- local repo contents are `INTENT.md`, `README.md`, a template `SCOPE.md`,
registry metadata, and this workplan
- the concrete implementation currently lives in
`../citation-evidence/src/anchor/`
- that upstream slice already contains selector creation/resolution logic,
PDF selector math, a PDF viewer adapter spike, scroll/highlight helpers,
and unit tests
- `../citation-engine` already exports the shared `Document`,
`DocumentRepresentation`, `Selector`, `AnnotationResolutionStatus`, and
`normalize()` surfaces the extracted code needs
Relevant upstream files already reviewed:
- `../citation-evidence/src/anchor/types.ts`
- `../citation-evidence/src/anchor/selectors/create.ts`
- `../citation-evidence/src/anchor/selectors/resolve.ts`
- `../citation-evidence/src/anchor/pdf-selector-math.ts`
- `../citation-evidence/src/anchor/pdf-viewer-adapter-spike.tsx`
- `../citation-evidence/src/anchor/scroll-job.ts`
- matching upstream tests under `../citation-evidence/src/anchor/`
## Non-Goals For This Ralph Slice
- full HTML/Markdown selector implementation
- a production-grade fuzzy re-anchoring system
- new persistence, binder, source-ingest, or workspace-shell behavior
- speculative architecture beyond what is needed to extract and verify the
existing anchor slice
- indefinite cross-repo cleanup without an explicit verification target
## Execution Order
```text
T01 boundary + package shape
-> T02 repo bootstrap
-> T03 pure selector/resolution extraction
-> T04 PDF adapter extraction
-> T05 citation-evidence cutover
-> T06 register remaining post-extraction gaps
-> T07 verification + state-hub close-out
```
## Task Breakdown
## T01 — Codify the repo boundary and initial package shape
```task
id: EANCH-WP-0001-T01
priority: high
status: done
state_hub_task_id: "ef88ff6a-590f-4858-a674-33f84c1d6116"
```
Turn the repo from an intent bucket into a concrete extraction target.
Scope:
- finish `SCOPE.md` so it reflects the actual boundary described in
`INTENT.md`, `SharedContracts.md`, and `ADR-0006`
- update `README.md` so it no longer points only at upstream ownership, but
states the package/API shape this repo is preparing to expose
- document the initial module layout for the first extracted version
(`selectors`, `resolver`, `pdf`, `highlight`, `tests`, public entrypoints)
- record what explicitly stays out of scope for this phase:
persistence, binder/work semantics, ingestion, and umbrella app shell
Acceptance:
- `SCOPE.md` is no longer a template; it names the extracted boundary,
current maturity, relevant dependencies, and non-goals
- `README.md` explains the package purpose, sibling-checkout install model, and
public module layout expectations
- the repo docs clearly distinguish:
`citation-engine` owns shared selector types;
`evidence-anchor` owns selector behavior and viewer contracts
Deliverables:
- finished `SCOPE.md`
- extraction-oriented `README.md`
- concise package shape documented in-repo
Done when a fresh agent can open this repo and know exactly what should move
here and what must stay elsewhere.
## T02 — Bootstrap the local TypeScript package and test harness
```task
id: EANCH-WP-0001-T02
status: done
priority: high
depends_on: [T01]
state_hub_task_id: "59c07bc6-7a80-4f58-b1cf-ee2f0c26e8ed"
```
Create the minimum package scaffolding needed to host extracted code.
Scope:
- add `package.json`, `tsconfig.json`, lint/test scripts, and a test runner
consistent with sibling repos
- define public exports for the package and for any subpath exports that need
to stay stable during cutover
- wire imports to `@citation-evidence/engine/shared` instead of local
`@shared/*` aliases from the umbrella repo
- ensure the repo can typecheck and run tests without importing
`citation-evidence` internals
Acceptance:
- the scaffold matches the existing `citation-engine` conventions closely
enough that extraction is mostly file movement plus import rewrites
- `pnpm test`, `pnpm typecheck`, and `pnpm lint` exist as local scripts
- the package exposes a stable public entrypoint and any necessary subpath
exports for the adapter slice
Deliverables:
- `package.json`
- `tsconfig.json`
- test/lint config files
- any required ignore / Node version files
Done when this repo can host the extracted code as a standalone TypeScript
package with only `citation-engine` as a shared-type dependency.
## T03 — Extract pure selector creation and resolution logic
```task
id: EANCH-WP-0001-T03
status: done
priority: critical
depends_on: [T02]
state_hub_task_id: "d7bff928-a022-4cc4-a151-950ffaaf622b"
```
Move the non-UI anchoring behavior out of `../citation-evidence/src/anchor/`.
Scope:
- extract and adapt:
`types.ts`,
`selectors/create.ts`,
`selectors/resolve.ts`,
`selectors/index.ts`,
`index.ts`,
and `pdf-selector-math.ts`
- port the matching unit tests:
`selectors/create.test.ts`,
`selectors/resolve.test.ts`,
and `pdf-selector-math.test.ts`
- keep the selector-ownership split intact:
selector data shapes remain in `citation-engine`,
selector behavior lives here
- preserve the current exact-match confidence ladder and selector redundancy
rules from `SharedContracts.md`
Acceptance:
- the extracted pure modules compile against `@citation-evidence/engine/shared`
imports, not umbrella-only aliases
- the three upstream unit-test groups pass locally in this repo
- no UI/viewer package dependencies are required for this task
Deliverables:
- extracted core source files under `src/`
- ported unit tests for selector creation, selector resolution, and PDF
selector math
- local exports wired through the package entrypoint
Done when the pure anchor modules pass locally in this repo and no longer
depend on the umbrella repo folder structure.
## T04 — Extract the PDF viewer adapter and highlight/scroll helpers
```task
id: EANCH-WP-0001-T04
status: done
priority: high
depends_on: [T03]
state_hub_task_id: "1deca610-8502-44e5-90c7-43e355489f55"
```
Move the PDF-specific adapter surface into this repo without leaking viewer
library types into engine/shared layers.
Scope:
- extract and adapt:
`pdf-viewer-adapter-spike.tsx`,
`scroll-job.ts`,
`highlight-styles.css`,
and `debug-textlayer.css`
- decide explicitly whether the first local export remains an explicitly-named
spike or is promoted to the initial `PDFViewerAdapter`
- keep `react-pdf-highlighter-plus` and PDF.js imports confined to the adapter
package boundary
- port `scroll-job.test.ts` and add a local demo or harness that still proves
select -> store selectors -> resolve -> scroll -> highlight
Acceptance:
- viewer-library imports exist only inside the adapter package boundary
- the scroll/highlight helper test passes locally
- a maintainer can identify the supported PDF adapter surface and its current
non-goals from the repo without reading the umbrella repo
Deliverables:
- extracted adapter and helper files
- local adapter export decision documented in code or README
- at least one runnable or inspectable local harness path for the PDF adapter
Done when the PDF adapter contract is owned here and the viewer-specific
implementation remains behind `DocumentViewerAdapter`.
## T05 — Cut citation-evidence over to the extracted package
```task
id: EANCH-WP-0001-T05
status: done
priority: high
depends_on: [T03, T04]
state_hub_task_id: "2fd9bd62-5d79-49b5-aee7-45e0a37313ba"
```
Replace the umbrella repo's internal anchor slice with a dependency on this
repo.
> **RESOLVED (2026-07-08).** The parallel `evidence-source` extraction landed
> (`citation-evidence@4ede979`), leaving `main` clean. The cutover was then
> executed and verified: umbrella typecheck + 95 tests + production build all
> green (`citation-evidence@d145148`). Package published as
> `@citation-evidence/evidence-anchor` with `.`, `./selectors`, `./types`, and
> `./pdf` exports; node-env consumers use the pure subpaths. Original blocker
> context retained below.
>
> **BLOCKED (2026-07-08, ralph loop iteration).** Extraction T01T04 are
> complete, committed, and verified green in `evidence-anchor` (30 tests,
> typecheck, lint). T05 was **not** attempted because the umbrella
> (`../citation-evidence`) has **another session's uncommitted work in
> progress on `main`** — a parallel `evidence-source` extraction:
> `package.json` adds `@citation-evidence/evidence-source` (link),
> `src/source/pdf/*` is deleted, and `tests/integration/anchor-source-roundtrip.test.ts`
> is already modified — the same shared file this cutover must edit (it imports
> both `@anchor/*` and the new source package). Forcing the anchor cutover into
> that dirty tree would entangle the two extractions and likely commit a
> non-building intermediate state. Needs human coordination: land/park the
> source extraction first, or agree how the two cutovers share the roundtrip
> test and `package.json`. The ralph loop was deactivated at this point.
>
> Cutover plan once unblocked (bounded — 4 import sites, all via `@anchor/index`):
> add `"evidence-anchor": "link:../evidence-anchor"`; repoint
> `PdfSelectionCapture` + `createSelectors``evidence-anchor`, and
> `PdfSpikeViewer`/`StoredAnnotation` + `getHighlightClientRects`
> `evidence-anchor/pdf`; drop the `@anchor` tsconfig/vite alias; delete or thin
> `src/anchor/`; run umbrella typecheck/test/build.
Scope:
- update `../citation-evidence` to consume `evidence-anchor` through a linked
package dependency instead of `src/anchor/` as the source of truth
- remove duplicate anchor logic from `citation-evidence` or reduce it to thin
compatibility re-exports during transition
- verify `citation-evidence` build/test flows still pass against the extracted
package
- update cross-repo docs so the ownership statement is no longer aspirational
Acceptance:
- `citation-evidence/package.json` points at `link:../evidence-anchor` (or the
equivalent local consumer path actually chosen)
- umbrella imports resolve through the extracted package instead of treating
`src/anchor/` as the canonical implementation
- `citation-evidence` build/test/typecheck remain green after the cutover
Deliverables:
- consumer dependency and import updates in `../citation-evidence`
- any temporary compatibility shims reduced to thin re-exports only
- updated ownership docs across the affected repos
Done when `citation-evidence` builds and tests against this repo and
`src/anchor/` is no longer the canonical home of anchor behavior.
## T06 — Register the post-extraction gaps instead of expanding the slice
```task
id: EANCH-WP-0001-T06
status: done
priority: medium
depends_on: [T05]
state_hub_task_id: "4e82ee7b-e813-441f-a41f-8f17a75fee57"
```
Current upstream code handles exact resolution plus PDF fallbacks, but it does
not yet satisfy the entire intent promised in `INTENT.md`. Those gaps should be
made explicit and queued, not silently folded into this extraction loop.
Scope:
- document the gap between the extracted MVP behavior and the broader
`INTENT.md` target for:
`stale`,
orphaned annotations,
fuzzy or recovery-oriented re-anchoring,
and HTML/Markdown selectors
- decide which gaps belong in one follow-on extraction-hardening workplan
versus separate format-specific workplans
- write the follow-on plan(s) or clearly register them in this workplan as
explicit next slices
Acceptance:
- no major promised behavior remains as "implicit future work"
- the next work after extraction is named concretely enough that another Ralph
loop can pick it up without re-discovery
- the current workplan stays bounded: no new broad implementation starts here
Deliverables:
- follow-on workplan section or new workplan file(s) for gap closure
- updated references in `README.md`/`SCOPE.md` if they previously implied those
features already existed here
Done when the extracted package ships with an honest, explicit map of the
remaining anchor work instead of vague future intent.
**Gap map (registered 2026-07-08):** the two follow-on workplans below cover
everything `INTENT.md` promises beyond the extracted MVP slice. `SCOPE.md`
already lists these under "Not in this extraction slice"; `README.md` points
here. No promised behavior is left as implicit future work.
- `workplans/EANCH-WP-0002-anchor-resolution-hardening.md` — stale/orphan
semantics, fuzzy/recovery re-anchoring, and promoting `PdfSpikeViewer` to a
production `PDFViewerAdapter` (existing PDF/text path).
- `workplans/EANCH-WP-0003-non-pdf-selectors.md` — HTML/Markdown `DomRange` +
`Structural` selectors and a non-PDF viewer adapter (new format track;
starts with a `citation-engine` shared-type contract change).
Both are `status: proposed` and will be registered in the hub by
`fix-consistency` (C-06) during T07 — not by hand.
## T07 — Verification, sync, and close-out evidence
```task
id: EANCH-WP-0001-T07
status: done
priority: high
depends_on: [T06]
state_hub_task_id: "e88623a9-38d0-4aeb-a7d7-6ec78342d57b"
```
Close the loop with machine-verifiable evidence and State Hub hygiene.
Scope:
- run the local verification commands for `evidence-anchor`
- run the affected verification commands for `citation-evidence` after cutover
- update task/workplan status, run `fix-consistency`, and log the required
progress note
- ensure the repo capability note and brief remain truthful after extraction
Acceptance:
- `pnpm test`, `pnpm typecheck`, and `pnpm lint` are green in this repo
- the relevant `citation-evidence` verification commands are green after
consumer cutover
- `fix-consistency` passes and the workplan can be moved from `active` to
`finished` without status drift
Deliverables:
- verification evidence in commit history and/or progress note
- synced State Hub task/workplan state
- clean handoff for the next anchor follow-on workplan
Done when the extraction is verified end-to-end and the workplan can retire
cleanly under HEUREKA instead of stopping at "probably finished".
**Verification (2026-07-08):**
- `evidence-anchor`: `pnpm test` 30 passed (4 files), `typecheck` clean,
`lint` clean.
- `citation-evidence` (post-cutover, `d145148`): `pnpm typecheck` clean,
`pnpm test` 95 passed (26 files), `pnpm build` succeeded.

`f32b500` T05 (umbrella `d145148`) · `0871f79` T06. Workplan frontmatter set to

# 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: done
priority: high
state_hub_task_id: "940b03ba-4b2f-4d1a-b7bc-72813817549d"
```
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: done
priority: medium
depends_on: [T01]
state_hub_task_id: "f75b94cd-bfb8-47f9-bd89-0d605f925290"
```
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: done
priority: high
depends_on: [T01]
state_hub_task_id: "8548fa44-5bb3-40cf-b8f8-e745deae7dda"
```
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: done
priority: medium
depends_on: [T03]
state_hub_task_id: "6a7163f5-39ca-48fa-8941-8459c563198f"
```
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: done
priority: high
depends_on: [T02, T04]
state_hub_task_id: "1ea0885a-c541-438f-a4fd-b8be0773b373"
```
`pnpm test`/`typecheck`/`lint` green here; umbrella typecheck/test/build green
after any contract-visible change; `fix-consistency` clean; progress note.
**Verification (2026-07-09):**
- `evidence-anchor`: 42 tests (9 files), typecheck + lint clean.
- `citation-evidence`: typecheck clean, 51 integration tests passed.

# 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.
