+## [1.9.0] - 2026-08-01
+
+The canvas audit. v1.8.0 rebuilt the interface around the canvas and never measured the canvas
+itself, so every pan, zoom and drag setting was still a React Flow default. Driving all 16 `init`
+templates through the running app, and running 8 interactions at 1920, 1440 and 390px, found 14
+defects. This release closes them. No backend contract changes, so the CLI, the MCP server and
+every API route behave exactly as in 1.8.0.
+
+### Fixed
+
+- **Every connection now draws an arrowhead.** The computed `markerEnd` on every edge was `none`,
+  so a directed architecture diagram showed no direction at all.
+- **Connection lines clear the contrast floor.** They rendered at 1.42:1 in light and 1.81:1 in
+  dark, against the 3:1 WCAG floor for meaningful graphics. `--edge` is now `#64748b` on the light
+  canvas at 4.55:1 and `#94a3b8` on the dark canvas at 7.3:1, solid instead of dashed and 1.6px
+  instead of 1px.
+- **The canvas zooms out far enough to fit a phone.** React Flow's 0.5 floor left 2 of 8 nodes
+  outside the pane at 390px, with the Zoom Out button already disabled on arrival. The floor is
+  now 0.12 and Fit View honours the same value, so all 8 fit at 0.29.
+- **A boundary no longer eats the drag that should pan the canvas.** Dragging a VPC moved the box
+  and its children by 113px, the VPC itself did not follow, and nothing saved the move. Boundaries
+  are decoration now: they take no drag, no click and no pointer event.
+- **A node is no longer trapped in its tier.** `extent: "parent"` against a box that hugged its
+  contents left a node 5 to 10px of travel and no way out. Nodes carry absolute positions, the
+  boundary re-fits around wherever they land, and a drag moves the full distance asked for.
+- **The Delete key removes a selected connection.** React Flow listens for Backspace alone by
+  default, so Delete did nothing to a selected edge. Both keys work.
+- **Connect-by-drag works at 390px.** Handles went from 6px to 9px with a 28px connect radius.
+- **A connection leaves the side of the node that matches the tier gap.** One pair of handles sent
+  a same-tier connection out of the bottom and back into the top of the node beside it. Neighbours
+  in a row now link straight across, anything further apart dips under the row, and a connection
+  that skips a tier runs down the outside. Connections that disappear behind a card they do not
+  touch fall from 17 to 5 across the 16 templates, and labels sitting on a card fall from 18 to 13.
+- **A tier orders its components before it places them.** A barycentre sweep puts connected
+  components near each other. Ties keep the spec's own order, so one spec always draws one picture.
+- **The VPC border clears the tier borders inside it.** Both rectangles came from the same
+  component positions with the same padding, so they shared a line in 12 of the 16 templates.
+- **Boundary colours come from theme tokens.** Hardcoded light `rgba` painted the VPC as a pale
+  slab on the dark canvas. Each tier keeps its hue and mixes its fill against the canvas.
+- **A card holds a fixed 260px, the width the layout reserves for it.** The card grew with its
+  content while the layout assumed 200px.
+- **A row centres on its nodes, not on the column slots they sit in.** The old form sat 50px off.
+- **Add Resource puts the resource in its tier.** It used to land on a fixed grid position that
+  collided with whatever the generated layout had already put there.
+- **The dead resize handle is gone.** `NodeResizer` rendered on every boundary with no handler to
+  keep a resize, so any resize vanished on the next change.
+
+### Notes
+
+- Catalog drag and drop still does not exist, and no documentation claims it. README and
+  `getting-started.md` say "drag components", which means dragging a node on the canvas, and that
+  works. `docs/competitor-landscape.md` lists a drag-and-drop designer as a competitor's advantage.
+- Connection crossings rise from 8 to 13 across the 16 templates. That is the deliberate half of
+  the trade: a connection crossing another connection stays readable, while one that vanishes
+  behind an unrelated card does not.
+

-## v1.8.0 rebuilt the canvas and stopped a mid-stream double bill
+## v1.9.0 gave the diagram arrowheads and got the canvas off React Flow's defaults
 
-- **One token set and a dark theme.** The theme follows your operating system until you pick a side.
-- **Every text colour clears the 4.5:1 contrast floor.** 29 sites did not.
-- **It works on a phone.** Below 900px the layout becomes a two-pane switch, and the nine tabs scroll.
-- **A mid-stream error no longer bills twice.** The old fallback ran a second generation over the first.
-- **A real `tablist` with arrow-key roving focus**, a live region for progress, `Cmd/Ctrl+K` for the composer.
-- **Panel results survive a tab switch.** The Export tab now offers all thirteen formats.
+Measured by driving all 16 `init` templates through the running app, and 8 interactions at 1920, 1440 and 390px.
 
-Earlier releases added control-ID mapping and `plan` (v1.5.0), the self-correcting architect and OSCAL (v1.6.0), and `cloudwright integrate` (v1.7.0). Full history in [CHANGELOG.md](CHANGELOG.md).
+- **Every connection draws an arrowhead.** The computed `markerEnd` was `none` on every edge.
+- **Connection lines clear 3:1 contrast.** They ran at 1.42:1 in light and 1.81:1 in dark.
+- **The canvas fits a phone.** The 0.5 zoom floor left 2 of 8 nodes off the pane at 390px; the floor is 0.12.
+- **A drag inside a VPC pans the canvas.** It used to drag the box out of shape and save nothing.
+- **A node moves the distance you drag it.** A tight boundary plus `extent: "parent"` allowed 5 to 10px.
+- **Connections stop hiding behind cards.** 17 of them did across the 16 templates; 5 still do.
