Three things, kept in one commit because they touch overlapping hunks of the
same two files and this environment has no interactive hunk staging. Splitting
them by file would have drawn boundaries that misrepresent what changed.
1. Step 4 of the map editor. A native OpenLayers PointerInteraction turns a
drag into a clamped constraint value, the ghost source shows it immediately,
and the solver's answer replaces a parallel set of preview layers while the
baseline layers are hidden rather than overwritten. Preview requests debounce
at 80 ms, pointerup flushes without waiting, and a newer request aborts the
one in flight; EditSession decides which answers count. Handle positions come
from the clamped value, so a handle stops at its limit instead of following
the cursor. Three of the four drag capabilities are live: edge offset,
sidewalk width, lane divider.
2. Road edge handles were drawn on the wrong side. offsetLine() offsets
counter-clockwise from the direction of travel and sidewalks use
`heading + (side === 'left' ? -90 : 90)`, so left is `tangent - 90`;
makeRoadHandles() placed the left handle at `tangent + 90`, over the right
kerb. Dragging the visually-left handle moved the right edge. Fixed on both
sides of the wire, with regression tests that name the sides geographically
rather than by axis sign.
3. Roads the junctions geometrically fill are now read-only. The 0.45 cap per
reserve made the existing `unavailable` branch unreachable, so a 14.5 m stub
between two junctions was offered a 1.5 m editable band with no room for the
transitions a road-interval constraint needs. Greying only affects the
manifest: constraints already saved against such a road keep being solved, so
the geometry output is unchanged and the fixture baselines do not move.
Range handles are built and unit-tested but hidden behind
`intervalEditingSupported`: compileGeometry() reads neither profile.interval nor
profile.transitions, so every edit applies to the whole road and the control
would have had no effect. Recorded in research/interval-not-applied.md, which
also blocks one PRD acceptance criterion.
The ol-ext probe stays in the tree as a manual harness; ol-ext is still not a
dependency.

Steps 1-3 of the main map road interval editor.
EditSession keeps the command stack, undo/redo and previewSeq arbitration as
pure logic with no OpenLayers reference, so all of it is unit-tested in node.
Pointer displacement converts to meters through EPSG:4326 and spherical
distance: treating a 3857 delta as meters desyncs the geometry from the cursor
by 1/cos(latitude). Handle drags project onto the axis the manifest declares
and clamp to its range, so the client never writes a coordinate into a road
polygon.
All of it sits behind a directEdit flag that defaults to off. With the flag off
the workbench requests no manifest, creates no extra source and registers no
interaction, so behaviour matches main.
The ol-ext probe passed its three gates but is not adopted for road handles.
Transform translates by the raw pointer delta, so a handle detaches from its
clamped constraint value: a drag reading -24.1 m produced a draft of -5.4 m.
Production needs the handle position derived from the constraint instead, which
means owning the position update, so native OL PointerInteraction will carry
the drag. ol-ext stays out of package.json; the probe is kept as a manual
harness. Reserve handles are unreachable with the current solver, recorded in
research/ rather than worked around.
Also names the dead backend when an API response is empty, instead of
surfacing "Unexpected end of JSON input" from response.json().

Planning: parent design.md becomes the single authoritative contract
(constraint model with 6 kinds, handle manifest, coordinate/unit
layering, preview sequencing, storage layout and lazy migration, area
config snapshot, API contract). Work is split into four independently
verifiable child tasks with per-step gates and rollback points.
Test infra: pin vitest 4.1.11, add test:client:unit for client pure
logic, extend prettier globs to root *.ts so vitest.config.ts is checked.
Add .gitignore: the repo had none, so inputs/, outputs/, workbench-data/
and the client build output were untracked rather than ignored.
