The assistant-ui markdown defaults (heading margins up to 32px,
20px paragraph margins, 24px list indent, 24px blockquote padding,
16px code padding) are tuned for the full-page Thread and waste
space in the narrow sidebar column. Scope tighter spacing to
.ask-fabro-sidebar for headings, paragraphs, lists, blockquotes,
and code blocks.

The assistant-ui markdown defaults size headings up to 36px (h1),
which dominated the narrow sidebar column. Scope smaller heading
sizes to .ask-fabro-sidebar: H1 18px bold, H2/H3 14px bold, H4-H6
14px normal (no special styling).

User message bubbles used the muted token (panel-alt), which composites
almost identically to the translucent bg-panel/40 sidebar — bubbles
visually disappeared into the column. Give them a solid panel surface so
they read as raised cards.
Also drop the composer's horizontal margin so the pill spans the full
sidebar width.

## Summary
Adds `/ask-fabro`, a prototype route that brings the right-docked "Ask
Fabro" assistant into the real web app. It graduates the sidebar design
from the `docs/superpowers/prototypes/2026-05-16-chats-new` prototype: a
placeholder workspace page with an "Ask Fabro" trigger that toggles an
animated 420px docked panel. The panel streams scripted, **fake** AI
replies through assistant-ui — no real model calls — matching the
behavior of the existing `/chats` prototype.
## What changed
- **`routes/ask-fabro.tsx`** — the route. A placeholder "Runs" workspace
(stat cards + recent-runs list) whose only job is to host the trigger
button, plus the docked sidebar. Uses `handle = { hideHeader,
fullHeight, wide }` and the edge-bleed wrapper copied from the shipping
`chats-layout`.
- **`components/chats/ask-fabro-sidebar.tsx`** — animated-width 420px
assistant panel rendering assistant-ui's `<Thread>`.
- **`components/chats/sidebar-composer.tsx`** — compact single-line
composer pill for the narrow column.
- **`app.css`** — the `.ask-fabro-sidebar` CSS block (narrow-column
overrides, layered into `assistant-ui` to beat its unlayered defaults),
ported verbatim from the prototype.
- **`router.tsx`** — registers the route under the AppShell.
The components and CSS are faithful, near-verbatim ports of the
prototype, which was carefully constructed. The runtime is fully reused
— `chats-runtime`, `chats-script`, `chats-types`, and `tool-fallback`
already graduated with `/chats`, so this PR adds no new chat plumbing.
## Decisions
- **Route-local state, not context.** The prototype used an app-level
`AskFabroContext` so the sidebar could mount above the top nav. This
route is self-contained, so a plain `useState` passed as props is
simpler and equivalent.
- **Sidebar sits below the top nav** (within the route), rather than
spanning the full window like the prototype. Intentional — keeps the
route self-contained.
- **Not added to the nav.** Reachable directly at `/ask-fabro`; it is
not `demoOnly`, so it renders regardless of demo mode.
## Verification
- `bun run typecheck`, `bun test` (403 pass), and `bun run build` all
clean.
- Rendered side-by-side against the prototype's `/sample`: empty state
and active thread (user bubble + streamed markdown assistant reply)
match.

## Summary
Ports the validated `/chats/new` and `/chats/:id` chat surface from
`docs/superpowers/prototypes/2026-05-16-chats-new/` into
`apps/fabro-web`. Client-side scripted prototype mounted inside the
existing `AppShell`; replaces `/start` as the planned new "kick off
agent work" entry point (but does not delete `/start` in this phase).
- New routes: `/chats/new` (empty-state composer) and `/chats/:chatId`
(active conversation with assistant-ui's `<Thread>`, scripted streaming
replies, markdown + tool-call rendering).
- Drives `@assistant-ui/react` + `@assistant-ui/react-ui` via
`useLocalRuntime` and a custom `ChatModelAdapter` that cycles a 6-entry
scripted reply bank.
- Tailwind v4 cascade fix: assistant-ui CSS is now imported via `@layer
assistant-ui` so v4 utilities cascade above the package's unlayered
scoped preflight. Includes a discovered Bun-specific tweak — see Notable
Deviations below.
- StrictMode-safe first-message handoff: store seeds the user message
into `seedMessages` with a `pendingResponse: true` flag, and
`chats-detail` triggers a single `runtime.thread.startRun({ parentId:
null })` then consumes the flag. Avoids the prototype's
autorespond-lost-stream race under React 19 StrictMode.
The Ask-Fabro right sidebar (also in the prototype) is **out of scope**
for this PR.

### `/chats/new` (empty state)
### `/chats/:chatId` (active conversation)
## Files
**New** (under `apps/fabro-web/`):
- `app/lib/chats-types.ts` — `Chat` wrapper + `ChatContentPart`
discriminated union over the API client's `CompletionContentPart`
- `app/lib/chats-script.ts` — 6-entry scripted reply bank
(`CompletionMessage[]`)
- `app/lib/chats-store.tsx` — Context + `useReducer` for chat metadata,
`pendingResponse` flag, scriptIndex
- `app/lib/chats-runtime.ts` — `createScriptedAdapter` +
`toThreadMessages` boundary converter
- `app/lib/test-utils.tsx` — minimal `renderHook` shim (lifts the
duplicated `IS_REACT_ACT_ENVIRONMENT` + dep-warning silencing pattern
out of `install-app.test.tsx`)
-
`app/components/chats/{tool-fallback,composer-chips,custom-composer}.tsx`
- `app/routes/{chats-layout,chats-new,chats-detail}.tsx`
- Tests: `chats-store.test.tsx` (5), `chats-runtime.test.ts` (4),
`chats-router.test.tsx` (3)
**Modified:**
- `package.json` — adds `@assistant-ui/{react,react-ui,react-markdown}`
(pinned exactly to versions verified in the prototype)
- `app/app.css` — `@layer` declaration + assistant-ui CSS imports into
`layer(assistant-ui)` + `.fabro-chat` `--aui-*` variable overrides
mapping to the Fabro palette
- `app/root.tsx` — removed `import "./app.css"` (see Notable Deviations)
- `app/router.tsx` — wires the chats routes under the AppShell tree
## Notable deviations from the plan
Two intentional deviations, both explained in their commit bodies:
1. **`apps/fabro-web/app/root.tsx` no longer imports `./app.css`.**
Bun's CSS bundler (used by `Bun.build` on `entry.tsx`) rejects
spec-valid `@layer name, name;` ordering between `@import` rules, even
though Tailwind's CLI accepts it. The CSS is built standalone by the
Tailwind CLI step in `scripts/build.ts` and linked from
`index.template.html`, so dropping the JS-side import bypasses Bun's
parser without any runtime change. A safety-net comment at the top of
`app.css` warns future engineers against re-adding the import. Commit:
`c37690be9`.
2. **`!` non-null assertions removed** in two places where the verbatim
prototype copy violated the global CLAUDE.md rule banning `!` in
production code: `chats-script.ts` now uses a typed `FALLBACK_REPLY` and
`??` coalescing; `composer-chips.tsx` lifts the first option of each
chip into a `DEFAULT_*` constant. `chats-runtime.test.ts`'s `for await`
drain loops were also replaced with `Array.fromAsync(...)` per the
no-loops-in-tests rule. Commits: `ace6ac6d4`, `652ad97af`.
## Test plan
- [x] `cd apps/fabro-web && bun run typecheck` — clean
- [x] `bun test` — 383 pass / 0 fail (12 new tests for chats)
- [x] `cd apps/fabro-web && bun run build` — succeeds; assistant-ui CSS
bundled into `dist/assets/app.css`
- [x] **Manual browser smoke test** — debug `fabro` binary running this
branch served `/chats/new` and `/chats/seed_email` correctly inside the
real AppShell with GitHub-OAuth auth (screenshots above).

Expose a run-scoped websocket terminal for Docker and Daytona sandboxes, and add the web terminal route so sandbox-backed runs can be inspected interactively from the run detail page.
Removes the light/dark toggle infrastructure in favor of a single dark
theme. Deletes the theme context, boot script, light-mode CSS overrides,
logotype-light asset, and the pierre-light diff theme. Collapses
graph-theme into a single constant. Adds scheme-only-dark on <html> so
native controls and the server-injected Graphviz @media query render
dark.

- introduce --color-on-primary (navy-950 in dark, white in light)
so text on bg-teal-500 reads clearly regardless of mode; swap
hardcoded text-navy-950 occurrences on teal fills for text-on-primary
- darken --color-fg-muted in light mode from slate-400 (#94a3b8) to
slate-500 (#64748b); slate-400 failed AA on the tinted page
- deepen page tint to #eef2f7 and strengthen line/line-strong so
white cards have real edges, not invisible hairlines

Light mode had the page at pure #ffffff with panels at #f8fafc — so
panels read darker than the page, the opposite of dark mode's
hierarchy and a big source of "blinding white" fatigue.
- page tinted to #f3f6fa (cool off-white, matching the brand's navy
palette) so it no longer glows
- panel set to #ffffff so cards, the nav, and auth panels pop
- panel-alt (#e9eef5) sits between them for recessed wells
- overlay / line colors shifted from pure black rgba to the navy tint
so the whole system reads coherent
Dark-mode tokens unchanged.

Add marked and @tailwindcss/typography to render markdown content as
HTML in the stage detail view instead of displaying raw text in a <pre>.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Fix run detail status: display actual API status (submitted, running,
succeeded, failed, etc.) instead of always showing "Working"
- Implement /runs/{id}/stages endpoint in non-demo mode, reading from
checkpoint + events to build stage list with statuses and durations
- Fix /runs/{id}/graph to fall through to durable store when run is not
in the live map
- Render real workflow graph SVG on overview and graph pages instead of
hardcoded demo graph; remove unused DotDiagram component from overview
- Add dark mode CSS overrides for server-rendered SVG graphs
- Wire stage detail page to real event data: fetch from /events, filter
by node_id, and render as system/assistant/tool blocks
- Fix stage page 500: use apiJsonOrNull for unimplemented /turns endpoint
- Filter start/exit graph control nodes from stage lists in the UI
