PDF text selection misbehaviour (some glyphs unselectable, selections
jumping to other positions) is almost always caused by misalignment
between the visible canvas-rendered glyphs and the invisible text
layer that PDF.js overlays for selection. There's no way to see this
without devtools — which makes it hard for end users to tell whether
a specific PDF is OCR-noisy, has bad font fallbacks, or has no text
layer at all.
This adds a developer-facing toggle in the SessionMenu ("Debug text
layer") that:
- paints every text-layer span yellow with a blue outline so it's
obvious where text is selectable and where it isn't, and
- logs every onSelection event to the browser console with the
captured text, page, normalized rects, and the selectors the
pipeline derived from it.
Preference persists in localStorage under
`citation-evidence:debug:textLayer`. Surfaced via a new
`useDebugFlag()` hook in @work so the SessionMenu (app layer) and the
ViewerShell (work layer) can both subscribe without breaching the
boundary plugin.

citation-evidence
A document-centered evidence workspace for capturing, managing, presenting,
and re-opening citations. The umbrella over the six-package design described
in INTENT.md and wiki/ArchitectureOverview.md.
During the MVP all code lives here under src/ (see "Repository layout"
below). Sister repos hold INTENT only — code migrates outward when each
subsystem stabilises.

The canonical contracts are in wiki/SharedContracts.md;
the partition boundaries are in wiki/DependencyMap.md.
Both are referenced from every workplan and from each sister repo's INTENT.md.
Repository layout
src/
shared/ # vocabulary, types, pure helpers → becomes part of citation-engine
engine/ # services, repositories, event bus → becomes part of citation-engine
anchor/ # selector creation/resolution, viewer adapter contract → becomes evidence-anchor
source/ # ingest, fingerprint, extraction, recovery → becomes evidence-source
binder/ # evidence-to-target binding, visual guide → becomes evidence-binder
work/ # review UI (sidebar, viewer shell) → becomes citation-work
app/ # the reference workspace shell → stays in citation-evidence
The dependency-edge rules between partitions are enforced by ESLint via
eslint-plugin-boundaries (see eslint.config.js). Extraction to a sister
repo is intended to be a git mv plus a package.json cut — nothing more.
Sister repos
Peers under ~/; each holds INTENT.md only during MVP:
~/citation-engine— shared model + engine services~/evidence-anchor— selectors + adapter contract~/evidence-source— ingest, representation, recovery~/evidence-binder— binding, visual guide, rect registry~/citation-work— review UI surfaces
Dev workflow
Requirements: Node 20 LTS (see .nvmrc) and pnpm 9.
pnpm install
pnpm dev # vite dev server (once src/app/ has a real entry)
pnpm test # vitest one-shot
pnpm test:watch
pnpm lint # eslint with boundary rules
pnpm typecheck # tsc --noEmit
pnpm build # production bundle
Workplans (Ralph)
Workplans drive incremental implementation through the ralph loop. The harness
lives in ~/ralph-workplan/; see workplans/README.md for the active list
and ordering.
/ralph-workplan workplans/CE-WP-0001-foundations.md
The loop self-retires when every task in the file has status: done and the
workplan's frontmatter status: done.
