Three phase plans for Wave 2 of the Nexus layout overhaul. Each plan
is self-contained with ownership boundaries, scope fence, file inventory,
implementation notes, acceptance criteria, and commit scheme — designed
for parallel subagent dispatch per MIGRATION-PLAN.md section 11.
Phase 9 (Assistant mode):
- Full-bleed chat at /assistant, no inner conversation list
- History slide-over (left) + Memory slide-over (right)
- Conversational home-state greeting replaces Dashboard
- ActionStrip with Promote/Attach/Memory/History
- New components: AssistantInputBar, ActionStrip, HistorySheet,
MemorySheet, AssistantHomeGreeting + useAssistantHomeStatus hook
- Owns: PersonalAssistant.tsx + components/assistant/**
Phase 10 (Studio mode):
- 8-card workshop grid replaces 7-tab ContentStudio
- ConvertPage folds in as 8th workshop (legacy /convert route kept)
- StudioPromptBar freeform input with keyword-based classifier
- Two-column workshop detail view (params left, preview right)
- Owns: ContentStudio.tsx + pages/StudioWorkshopDetail.tsx
+ components/studio/**
Phase 11 (Projects + Builder mode):
- ProjectCard with 72px Inter Black volt hero percentage
- 7-tab BuilderTabStrip (Overview/Issues/Agents/Gates/Costs/Activity/Org)
- Approvals -> Gates display-only rename
- OverviewTab with milestone checklist, origin chat card, activity
- Thin per-project wrappers reuse existing list components scoped
by projectId (escalate if not supported)
- useGateIndicator hook for the future Assistant dot notification
- Owns: Projects.tsx + ProjectDetail.tsx + components/projects/**
Ownership boundaries prevent parallel-dispatch file conflicts:
- App.tsx routing changes are controller-owned (post-Wave wiring)
- Each phase declares its file ownership and must not cross into others
- Existing list components reused as-is; escalate if not scope-compatible
- IconRail dot wiring for phase 11's gate indicator deferred to
post-Wave controller step
Dispatch pattern: three general-purpose subagents dispatched in parallel,
each handed the full plan text + the spec + ownership rules. Each
subagent implements its phase end-to-end with atomic commits per
logical unit. Controller reviews outputs after all three complete.

Task-by-task implementation plan for Phase 8 of the Nexus layout
overhaul (docs/specs/2026-04-11-nexus-layout-overhaul.md §13).
Seven tasks:
1. IconRail component + test
2. ModeBreadcrumb component + test
3. CmdKButton shim component + test
4. GlobalMicButton scaffold + test
5. TopStrip composite + test
6. Layout.tsx rewrite (mount new frame, kill old chrome)
7. Manual smoke test
TDD throughout (write failing test, run, implement, run, commit).
One commit per task. Execution via subagent-driven-development with
fresh subagent per task and two-stage review.
The plan includes complete code for every task (no placeholders),
exact file paths, exact test patterns matching the existing vitest
manual-createRoot pattern from ChatInput.test.tsx, and wire-up
details for preserving Layout.tsx's non-chrome responsibilities
(company-prefix URL sync, first-run onboarding, body overflow,
instance settings memory, dialog overlays).
