 ## Add the Handoff Report page
 
-When Handoff Report is enabled, the Server hosts the scope Handoff page at `/handoff-reports` without requiring the scoped-statistics Dashboard or its configured scope list. The optional Dashboard remains at `/` when separately enabled. The pages share only `base.html`, the header and footer, `auth.js`, theme state, and locale state; their statistics and report calculations remain independent.
+When Handoff Report is enabled, the Server hosts a read-only report page at `/handoff-reports`; the Dashboard remains
+optional. Both pages load Scopes from `/dashboard/scopes` and use `scope-selection.js` to expose the same `all`,
+`subtree`, and `exact` views.
 
-The Handoff Report page obtains exact `scope_id` values with committed Handoffs from `POST /v1/handoff-reports/scopes/list-known` and uses them in a searchable scope combobox. Selecting a scope sends its required `scope_id` to `POST /v1/handoff-reports/get`; neither the Project catalog nor `project_id` participates in report selection. The page presents the exact current Handoff snapshot at full width.
+The page posts the selected `ScopeSelection` to `/v1/handoff-reports/get`. The Server resolves it to exact Scope IDs
+and projects each Scope's descriptor and latest exact Handoff. A Scope without a committed Handoff remains visible as
+`no_handoff`. Parent does not infer Context sharing, and the report does not edit Handoff state.
 
-The current snapshot displays objective, current state, disposition, next action, and known omissions as one Handoff document. One Edit action opens all five fields, and one Save Revision action prepares and commits the complete document as a new immutable Handoff Revision. Scope switching and background refresh pause while the editor is open. Receiver-side decisions are not part of this page; existing continuity records remain available in the read-only Continuity timeline. Apart from the explicit revision write, the browser formats returned `summary`, `coverage`, Workstream state, and digests without recalculating report semantics.
-
-When known-scope discovery succeeds but no scope has a committed Handoff, the page replaces report controls with a clearly labeled, data-free template preview. Retry enumerates Handoff heads again; the first committed scope replaces the preview. The preview neither creates a Handoff nor requests fabricated report data.
-
-The page requests the current day in UTC by default and provides current-day, ISO-week, calendar-month, and custom date-range inputs. The custom end date is inclusive in the UI and is converted to the exclusive start of the next day for the API. The current scope application normalizes this input but supplies no Activity events, reports `activity_coverage=not_configured`, and returns no period comparison. Handoff status comes from the current exact selection and must not be presented as a historical period-end state.
-
-The overview request may disable evidence checks for lower latency. A Markdown download makes a separate request with `format=markdown`, `download=true`, and evidence checks enabled by default. The browser never reconstructs Markdown from rendered DOM or canonical JSON. Both background refresh and browser download currently require a stored bearer token even when Server authentication is disabled; initial and manual report loads still work without one. Disabling Handoff Report removes the `/handoff-reports` page and its API while leaving the original Dashboard route, scope selection, and statistics request unchanged.
+JSON is the browser projection. Markdown download repeats the same selection with `format=markdown` and
+`download=true`; the browser does not reconstruct Markdown from the rendered DOM. Disabling Handoff Report removes

 `交接`, `交接当前工作`, and `commit a handoff` use the same behavior. To inspect the proposed content without writing,
 ask to `preview the handoff without committing`; the Skill renders the proposed fields in chat and calls no write
 tool. Discussing Handoff design or asking how it works does not authorize a write.
 
-Codex resolves scope in this order: an explicit `POWERCONTEXT_CODEX_SCOPE_ID`, a Workstream scope persistently bound

-same workspace reuse that scope.

-The picker returns the Workstream's human-facing `work_id` and authoritative `scope_id`. The `project-context` Skill
-passes that exact scope to the resolver's `--bind-workstream` operation and verifies the result. The binding lives in
-`powercontext/codex-workspace.json` below the Git-private directory, outside the worktree and commits. A one-line
-Handoff then continues the selected Workstream's Artifact lifecycle and creates the next Revision. If the MCP client
-does not support native elicitation, the tool returns structured choices instead; the integration must still obtain an
-explicit selection and must not choose silently.
