Why: the adjudicated plan (D1-D4) calls for office/link previews with
loaders injected from the host, right-rail light preview alongside the
overlay viewer, and artifact deletion kept as an API capability with no
UI entry.
Evidence: previewsetup.ts injects docx (mammoth), xlsx (SheetJS, sheet
tabs, 200-row cap), pptx (pptx-preview full-fidelity; pptx2html was
dropped for a broken module entry — tXml case mismatch breaks Linux
builds — per the D2 fallback clause), and the /api/url-preview fetcher,
all via dynamic import: the main entry grows ~12KB while xlsx (430KB),
pptx (1.2MB) and jszip (98KB) load on first preview. DocViewer becomes a
FilePreview container (keeps text-family editing); Workbench gains a
preview tab with rail-preview state (store.railPreview); artifact chips
and panel rows gain a rail-preview action; the panel delete button is
removed while api.deleteArtifact and DELETE /api/artifacts/{id} remain.
tsc clean; vitest 33 passed; production build succeeds.
Impact: previews work end to end for the whole format matrix; deletion
stays plugin-reachable only.

Why: agents rediscovered Gitea hosts and credential locations from
scratch each session, and the retired git-panel host kept failing with
TLS broken-pipe errors before the right host was recalled.
Evidence: curl git-home...:30319/api/v1/version with token from
~/.secrets/gitea -> {"version":"1.27.3"}; ssh -p 31411 git@git-ssh...
(BatchMode) -> "Hi there, weichen!" with key ~/.ssh/home_gitea (ED25519,
SHA256:GYXaOXIMeloQ1fKSfdJ/ndgPQzs/Ix7Hk62ekfkfQ20). Same section already
merged in Agent-System-Dev (PR #73).
Impact: AGENTS.md only; records hosts and credential locations, no
secret values (baseline hard boundary 2).
Refs: Agent-System-Dev PR #73
Why: AssistantMessage reordered a message's parts by the process flag,
so tool calls floated above the text that surrounded them instead of
appearing where they actually ran; live streams had the same defect via
a fixed template order and never showed artifacts mid-run. Generated
files (e.g. meeting-minutes docx) had no visible download path, the
artifacts panel was a bare list, DocViewer nested a modal inside the
overlay, and settings rows used a legacy grid with a floating save
button.
Evidence: messageparts.ts adds groupParts (order-preserving grouping of
consecutive process parts, unit-tested) plus humanSize/artifactIcon
helpers; Conversation renders blocks in original order and the artifact
chip becomes icon + open + download; LiveState.parts accumulates events
in arrival order including artifact_ref so live view matches the
persisted message; ArtifactsPanel gains search/kind filter/upload and
per-row preview/download/delete-confirm; DocViewer is a single-layer
OverlayHost with pdf iframe, csv/json monospace, and a binary info card
with a download CTA; SettingsModal migrates to @ui SettingRow with the
save button pinned in the shell actions bar; inbox cards receive the
docBridge so result cards can open artifacts. tsc clean, vitest 20
passed, production build succeeds.
Impact: message timelines read in true execution order during and after
runs; every artifact is previewable and downloadable from the message
chip, the workspace panel, and the viewer; settings render on the fixed
two-column shell.
Refs: task feature/chat-order-artifact-files (ui# c3e1f3b backend#
44b51fa).
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.
