The slice 02 preview component had no entry point — neither the file tree
(空间目录) nor the turn summary (轮次总结) reached it. Slice 12 wires both
through ONE shared action so a click in either place lands on the same
right-hand preview surface (file-preview-pane).
Action: lib/open-file.ts owns the single-source 'open.file.in.web'
contract — openFileInWeb(path) is the only way to open a file, both entry
points call it, persistence (localStorage 'webui:open-file:path') makes a
refresh reopen the same file. The companion webapp unit test pins the
contract at three levels: module behaviour, source-tree single-source
(grep the webapp for callers), and the page-level panel-open discipline.
Entry 1 (file tree): panels.tsx FilesPanel renders FileRow as a clickable
button (testid files-tree-file-open) that calls openFileInWeb; the
hover-only 'copy absolute path' button is unchanged.
Entry 2 (turn summary): chat.tsx ActivityGroup → ToolCard renders
block.toolPaths (the server's '@ /path' body lines) as clickable buttons
(testid tool-card-path) that call the page-level onOpenFile handler. The
handler sets the path AND auto-opens the files panel when it is closed,
so the preview the user triggered is the one they see.
Honest limitation: the slice-12 wiring is in place for the turn-summary
entry, but the current session transcripts in the dev DB don't carry the
server's 'locations' data, so the per-file chips aren't visible on those
specific sessions. The wiring is correct and a session whose tool updates
include locations will render clickable path chips as designed.
Persistence key: webui:open-file:path (localStorage). Slice 07 owns the
cross-restart durability migration; this slice only adds the per-file
'refresh reopens same file' guarantee.
Gates: webapp typecheck 0; test:webapp 406/406 pass; webapp build ✓;

Subject: [PATCH 2/3] fix(test): stub window via globalThis instead of
redeclaring it
CI's webapp:typecheck rejected the test with TS2403/TS2322: the
disabled-storage case redeclared the ambient 'window' global with a
structural type narrower than the DOM lib's Window & typeof globalThis.
Install the stub with Object.defineProperty on globalThis instead, which
keeps the same behaviour under test (storage disabled must not throw at
import time) without shadowing the ambient declaration.
webapp:typecheck (CI entry point): clean.

Conflict resolution threaded slice 12's onOpenFile through slice 07's
ScrollRestoredChat wrapper so the turn-summary file chips survive the
merge: ChatProps keeps both slices' optional props, page.tsx keeps both
import sets, and ScrollRestoredChat forwards onOpenFile to the inner Chat.
