Why: T2 frontend of the inbox (D25): the inbox is the first tab with a live
pending count; card events (created/updated/status/resolved) upsert the
projection in real time; confirm-projection cards route clicks back to HITL
resolution (run resumes, server syncs both sides); other actions call the
cards API and append the server-persisted receipt into the timeline.
Evidence: tsc + build green; vitest 9/9; card state resets/refreshes on
conversation open and reconcile.
Impact: default right tab becomes 收件箱 (localStorage-persisted preference
still honored for existing users).
Refs: modules/documents docs/proposals/2026-09-30-ui-inbox-command-workspace.md
Why: Core T1 added ActivityCard, card.* events, HITL anchoring fields and seven
UI vocabularies; this repo's contracts.ts is the generated mirror.
Evidence: make contracts from Core main; frontend vitest 9/9 still green
(additive types, shape tests unaffected).
Impact: Types available for T2 inbox implementation; no behavior change.
Refs: Agent-System-Documents proposal 2026-09-30-ui-inbox-command-workspace
Why: The schema renderer and design tokens moved to the new Agent-System-UI
repo (D29); Frontend becomes the first host consuming it through the @ui
source alias so future inbox/card/workspace components land in the shared
library instead of this repo.
Evidence: tsc+build clean with modules/ui materialized; vitest 9/9 pass;
combined CSS (tokens.css + ui.css + styles.css) verified rule-identical to
the pre-migration styles.css except comments and a collision-free block
relocation; doc-ref store access replaced by injected DocBridge at the two
call sites (plugin panels, card parts, HITL forms).
Impact: Requires sibling modules/ui checkout (Dev worktree provides it); vite
dedupe keeps single react/marked copies in the bundle.
Refs: Agent-System-Documents proposal 2026-09-30-ui-inbox-command-workspace (D29)
Why: the composition adopted the delivery gate (Dev repo ef89fc8); resident
entry rules must carry the gate so agents load them without reading the
guidelines submodule first.
Evidence: text-only entry change; gate mechanics validated in the Dev repo
scratch-repo suite (19/19) and merged as PR weichen/Agent-System-Dev#1.
Impact: entry doc only; no code, contract, or build change in this repo.
Refs: Development-Guidelines 0.1.0-draft.7; Agent-System-Dev ef89fc8
Details (original message):
Implement the three-column workbench frontend: resizable/collapsible nav with overshorthand collapse, streaming chat with part renderers and process collapse, HITL choice cards with impact display and free-input pivot, plan/todos/artifacts/agents tabs, subagent tracker modal, schema-driven settings center with effect badges and masked secrets, profile management with import/export, plugin panel rendering, doc viewer with edit-save; contract shape tests.
