E2 · Identity & naming

[hellno]

Goal

Fix P1 #1 (identity): kill the literal "Wallet" as a UI label; make the breadcrumb name the entity (drop Personal ›); render the wallet-home masthead; give wallets a deterministic default name and agents auto-assigned, renamable handles (retire "Atlas").

Depends on / blocks

• Depends on: E1.
• Blocks: E8 (⌘K coverage).

Do not touch

• The review/activity/tx flows.

Acceptance criteria

• Literal "Wallet" killed at shell_chrome.rs:73 (Selection::Wallet => "Wallet") and palette.rs:205.
• Breadcrumb names the entity; Personal › dropped (shell_chrome.rs:284-287).
• Wallet-home masthead renders (name + identity_mark above the mono hero).
• Deterministic default wallet name.
• Agent handles auto-assigned and renamable.
• Reflective test asserts "Wallet" appears nowhere as a UI label.
• Wallet home checklist passes; before/after screenshots attached.

Files

• shell_chrome.rs, palette.rs, wallet-home view, a handle generator, widgets.rs.

Golden-ref fidelity — designs/deckard-v4.html view home (Wallet home)

• Sidebar top group is WALLETS (no PROJECTS); Agents show a handle + status; Connections show favicon + domain.
• Breadcrumb is the entity name only (e.g. Meridian) — no Personal ›, no literal "Wallet".
• Identity masthead: name + identity_mark above the mono hero.
• Hero mono, dimmed decimals; meta line $… · synced … · verified on mainnet (honest fallback off mainnet / no price).
• Actions left-anchored (Shield primary; Send/Receive/Swap ghost).
• Waiting strip is ONE line (N waiting for you · Review → amber, else Nothing waiting for you.) — not a stacked band.
• Holdings: Asset · Balance · 24h · $ Value, mono, decimals aligned on the point across rows.
• Right rail "This wallet": sync/verified/network + cap ledger + Connections/Agents kv rows.

Part of the v4 epic #179. Implements #170.

[hellno]

E1 (#189) shipped primitives for this issue (in crates/deckard-app/src/widgets.rs):

• agent_mark(seed, size, radius, agent, agent_tint) — the handle-aware bordered cyan squircle (renders K for Kyoto, not a fixed A). Migrate the sidebar / breadcrumb / feed off the fixed-A shell_chrome::agent_squircle onto this, then retire the old one.
• page_header(mark, title, subtitle, primary, muted) — the ONE masthead/header anatomy (kills the hand-rolled headers at three sizes).
• origin_header / Origin — the actor identity when you need the You/Agent/Dapp rail.
• Shared monogram(seed) backs both identity_mark and agent_mark.
