 # Design Direction — Clinical KB
 
+## July 1 — Clinical White / Aegean Graphite (active direction)
+
+This supersedes the earlier "single teal accent for primary actions" principle. The colour system is now **role-split** rather than single-accent:
+
+- **Command = graphite.** Primary actions (New chat, primary CTAs, the mobile section FAB) use `--command` (`#111827` light / near-white `#F5F7F7` dark) — never teal/green.
+- **Clinical accent = Aegean.** A cool blue-teal `--clinical-accent` (`#0B6F86` light / `#4CCFD0` dark) owns clinical identity only: selected mode, evidence/source rails, the composer send action, and focus.
+- **Green = success only.** `--success` is reserved for ready/connected/complete; it is never brand, nav, command, send, or evidence.
+- **True-white canvas.** The neutral ramp was de-blued to a true-neutral gray scale; the content surface is `#FFFFFF`, with `--surface-chrome` (`#F7F8FA`) for rails/header only. Light mode is de-glassed: flat surfaces + hairline borders + one restrained shadow; glass/blur is reserved for overlays. Dark mode keeps its black polish.
+
+Migration was token-led: `--primary*` now resolves to the Aegean accent, `--command*` is new, and legacy `--clinical-chat-teal*` / `--clinical-chat-ready` are retained as compat aliases pointing at the role tokens (`--clinical-accent` / `--success`). New code should reference the role tokens directly. Typography (Geist), spacing, radius, and motion are unchanged from below. See decision log **D11**.

 ## June 20 scoped run
 
 The active direction for the dashboard and document viewer is a quiet clinical command instrument: neutral, precise, source-first. Teal remains reserved for primary action, evidence, and focus; dense operational details should collapse into progressive sheets/drawers on mobile rather than competing with the answer or PDF.

 **Why better:** The PDF regains priority on mobile when there is no citation to inspect, while source evidence remains discoverable and anchored for navigation.
 **Rejected:** Removing the evidence anchor entirely (would weaken navigation and tests); always showing the full card (kept the original hierarchy problem).
 **Verification:** Focused eslint and `npm run typecheck` pass; pinned evidence and PDF ordering are included in visual QA.

+## D11 — Clinical White / Aegean Graphite: role-split colour
+
+**What:** Split the overloaded accent into three roles. Added `--command` (graphite) for primary actions, `--clinical-accent` (Aegean blue-teal) for clinical identity (selected/evidence/send/focus), and reserved `--success` (green) for status only. De-blued the neutral ramp to true-neutral gray, set the content surface to `#FFFFFF` with a new `--surface-chrome` for rails/header, and de-glassed light-mode materials (flat + hairline + single shadow; glass kept for overlays). `--primary*` now resolves to the Aegean accent; `--clinical-chat-teal*`/`--clinical-chat-ready` retained as compat aliases pointing at the role tokens.
+**Why better:** `--primary` previously drove both command buttons and evidence surfaces, so nothing read as deliberate. Roleization makes command vs clinical-identity vs success visually distinct, yields a crisper premium white, and keeps the black-polish dark mode.
+**Rejected:** Keeping teal as the primary-action colour (accent keeps doing two jobs); a mass rename of the ~265 `--clinical-chat-teal` call-sites (unreviewable churn — aliases achieve the same end); a warm/cream canvas (the brief's premise; the real issue was blue-grey murk, not warmth).
+**Verification:** `npm run typecheck` passes; dev server compiles and serves 200 with 0 console errors; light/dark desktop + mobile screenshots confirm graphite command, Aegean send/evidence, and success-only green; contrast spot-checks — Aegean on white ≈5.8:1, command ≈16:1, soft text ≈5.0:1, semantics ≥4.5:1.

 # Changelog — Premium Redesign
 
+## July 1 — Clinical White / Aegean Graphite
+
+### Rebuild
+
+- **Role-split colour system:** graphite `--command` for primary actions, Aegean `--clinical-accent` for clinical identity (selected/evidence/send/focus), green `--success` for status only. Splits the previously overloaded `--primary`. See decision log **D11**, direction doc updated.
+- **True-white canvas:** de-blued the neutral ramp to true-neutral gray; content surface `#FFFFFF` + new `--surface-chrome` for rails/header; light-mode materials de-glassed (flat + hairline + one shadow; glass kept for overlays). Dark mode keeps black polish, brightened Aegean accent.
+
+### Upgrade
+
+- **Command controls:** sidebar/header New chat and the mobile section FAB now read graphite; the composer send button reads Aegean.
+- **Active states:** sidebar tool tiles, recent-chat, and the header mode menu use rail + icon + graphite label instead of broad teal fills.
+- **Semantic hygiene:** medication match badge moved off hardcoded `emerald-*`/`blue-*` onto accent/info role tokens; status dots resolve to `--success`.
+
+### Verification
+
+- `npm run typecheck` passes; dev server serves 200 with 0 console errors; light/dark desktop + light mobile screenshots confirm the direction; contrast spot-checks pass (Aegean-on-white ≈5.8:1, command ≈16:1, semantics ≥4.5:1). `npm run verify:ui`/`verify:release` not yet run in this pass.
