+## Problem
+
+- [TaskPage.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/TaskPage.tsx:1025) renders `GHStatusCell` with only `Open` and `Closed`.
+- [TaskPage.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/TaskPage.tsx:1064) sends `{ state: 'closed' }`, so the list path cannot choose GitHub close reasons.
+- [TaskPage.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/TaskPage.tsx:1137) styles closed issues with rose/destructive color, while GitHub treats closing as a neutral/purple completion action rather than a delete/error action.
+- [GitHubItemDialog.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/GitHubItemDialog.tsx:4960) has a separate issue-detail status popover; it must expose the same close reasons so opening an issue from Tasks does not fall back to the old Open/Closed-only UI.
+- [GitHubIssueCommentComposer.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/github/GitHubIssueCommentComposer.tsx:188) already supports close reasons in the detail composer, but the Tasks list does not.
+
+## Goal
+
+Bring the GitHub Tasks list status menu closer to GitHub:
+
+1. Closed issue UI must stop using destructive red styling.
+2. Open issues must expose close-as-completed, close-as-not-planned, and close-as-duplicate from the status menu.
+3. Duplicate closes must require a target issue number and pass it as `duplicateOf`.
+4. Reopening still works from the same status menu.
+5. GitHub issue detail metadata must use the same close-reason and duplicate-picker behavior as the Tasks row.
+
+## Non-goals
+
+- No provider-generic changes for GitLab, Linear, or Jira.
+- No network-backed GitHub issue search picker in this pass; the duplicate picker uses the loaded Tasks cache plus an exact issue-number fallback.
+- No schema changes or cache migration.
+- No change to PR status behavior.
+- No automatic cross-window broadcast beyond the existing cache/list refresh mechanics; this pass updates the current renderer optimistically and relies on normal refetch in other windows.
+
+## Design
+
+1. Add a small TaskPage GitHub status menu model in a named module, including option metadata, duplicate-target validation, and payload construction for close reasons.
+2. Update `GHStatusCell` so `handleStateChange` accepts close options, optimistically patches only the issue `state`, and sends `stateReason` plus optional `duplicateOf`.
+3. Route issue-state mutations by issue identity:
+   - If the row URL parses to `owner/repo`, use `github.project.updateIssueBySlug` / runtime `github.project.updateIssueBySlug`. This avoids closing the wrong repository for GitHub project/custom-source rows whose issue repo can differ from the caller repo.
+   - Otherwise keep the existing `github.updateIssue` path with `repoPath`/`repoId`/`sourceContext`.
+4. Render the status popover with `Open`, `Close as completed`, `Close as not planned`, and `Close as duplicate` in both the Tasks row and issue-detail metadata sidebar. The duplicate row advances to a second-step picker with a back button, search field, loaded issue candidates, and an exact-number fallback.
+5. Replace rose closed-state classes with token-based primary/ring color-mix classes so the closed pill is completion-like, not destructive. Keep the open-state green treatment for parity with the existing Tasks page unless a broader status-color pass changes it.
+6. Keep the payload serializable for IPC/runtime/SSH: `{ state, stateReason, duplicateOf }` only contains strings and numbers.
+
+## API Notes
+
+- The local path in [issues.ts](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/main/github/issues.ts:231) already closes issues with `gh issue close`. Preserve that model and pass:
+  - `--reason completed` for `stateReason: 'completed'`
+  - `--reason "not planned"` for `stateReason: 'not_planned'`
+  - `--duplicate-of <number>` for `stateReason: 'duplicate'` with `duplicateOf`
+- The slug path in [mutations.ts](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/main/github/project-view/mutations.ts:160) must not implement duplicates by PATCHing `duplicate_of` on `repos/{owner}/{repo}/issues/{n}`. `gh issue close --duplicate-of` is the supported CLI surface already used by the path-based mutation, so slug-addressed state changes should use `gh issue close/reopen --repo owner/repo` for state and reserve REST PATCH for title/body.
+- When `stateReason: 'duplicate'` is sent without a valid `duplicateOf`, reject it before dispatch. Do not silently downgrade to plain closed or `--reason duplicate`, because GitHub's duplicate UX expects the target issue to be recorded.
+- Keep `state_reason` REST PATCH only for non-duplicate close reasons if the implementation deliberately stays on REST for completed/not-planned. The simpler consistency target is to route all slug-addressed state changes through `gh issue close/reopen`.
+
+## Data Flow
+
+- User opens a GitHub issue status pill.
+- Completed/not-planned click -> `handleStateChange('closed', { stateReason })`.
+- Duplicate click -> second-step picker -> select a loaded issue or exact target number -> `handleStateChange('closed', { stateReason: 'duplicate', duplicateOf })`.
+- Cell optimistically patches local state and store row state.
+- Mutation goes through local IPC or runtime RPC with the same repo/source context.
+- Failure reverts the local/store state and shows the existing error toast.
+- Success records the existing `github-tasks` feature interaction and should invalidate or refresh the relevant work-items cache entry if the current filter can hide the row after the state changes (for example, an `is:open` filter). Without that, a closed row can remain visible until a later refetch.
+
+## Edge Cases
+
+- Duplicate target is blank, zero, negative, decimal, or the same issue number: keep the picker open and show inline validation after Enter.
+- Duplicate target can be a different repository's issue only when the implementation accepts a URL; this pass takes a loaded same-repository issue or number, so validation and copy should describe it as an issue in the same repository.
+- The row refreshes while the menu is open: reconcile the optimistic draft before paint as the current status cell already does.
+- Rapid repeated choices: retain the existing request id guard so stale responses cannot revert a newer choice.
+- SSH/runtime target: payload must remain serializable and use the existing runtime method.
+- Multi-window consistency: do not assume another window's in-memory `workItemsCache` observes the optimistic patch. Ensure the mutation path updates GitHub authoritatively and that normal cache invalidation/refetch behavior eventually corrects other windows.
+- Project/custom-source rows: prefer the parsed issue URL slug over the selected local repo when available, because a GitHub Project can contain issues from repositories other than the current worktree.
+- PR rows and rows without a repo continue to render a non-editable status pill.
+- Rows without a parsed slug and without a local repo/source context should stay non-editable; do not attempt a mutation from only an issue number.
+
+## Test Plan
+
+- Unit: menu model builds `{ state: 'closed', stateReason: 'completed' }`, `{ state: 'closed', stateReason: 'not_planned' }`, and duplicate payloads only for valid duplicate targets.
+- Unit: duplicate validation rejects missing/self/non-positive/non-integer targets.
+- Existing unit: optimistic status draft reconciliation remains unchanged.
+- Main unit: `updateIssue` emits `gh issue close --reason completed`, `gh issue close --reason "not planned"`, `gh issue close --duplicate-of <n>`, and `gh issue reopen`.
+- Main unit: `updateIssueBySlug` uses `gh issue close/reopen --repo owner/repo` for state changes, rejects duplicate without `duplicateOf`, and does not send unsupported `duplicate_of` REST fields.
+- Renderer unit: `GHStatusCell` uses slug-addressed mutation when `item.url` contains an owner/repo and falls back to `github.updateIssue` only when slug parsing is unavailable.
+- Store/cache unit: successful close from an open-filtered Tasks list invalidates or refreshes the affected work-items cache so hidden-by-filter rows do not linger indefinitely.
+- Electron validation: Tasks GitHub issue row status menu shows the new close options and closed issue pill is not red.
+- Electron validation: duplicate close picker appears after the duplicate action and supports issue search/exact-number fallback. Do not submit a real close mutation against user data.
+- Electron validation: GitHub issue detail status sidebar shows the same close options and duplicate picker as the list row.
+- Electron/runtime smoke: same menu opens and validation works when the active runtime target is an SSH/environment source; avoid a real close mutation unless using disposable test data.
+
+## UI Quality Bar
+
+- Popover should feel like an action menu, not an error/destructive confirmation.
+- Closed issue pill must be visually distinct from open but not red/destructive.
+- Duplicate picker must fit in the popover at desktop and narrow widths without clipping.
+- Hover, focus, disabled, and inline validation states use existing shadcn primitives/tokens.
+
+## Review Screenshots
+
+1. GitHub Tasks issue row with status popover open showing all close reasons.
+2. Duplicate close second-step picker with search and issue candidates.
+3. Closed issue row/pill showing non-red completion styling.
+4. GitHub issue detail sidebar status popover showing all close reasons.
+5. GitHub issue detail duplicate close second-step picker.
+6. Adjacent smoke: GitHub Tasks header/search area still renders normally.
+
+## Rollout
+
+1. Add status menu model and tests.
+2. Update `GHStatusCell` UI and mutation payload.
+3. Run focused tests, typecheck, and lint.
+4. Run UI quality review.
+5. Validate in Electron and capture screenshots.
+
+## Lightweight Eng Review
+
+- Scope: kept to the GitHub Tasks status cell plus a small model module; no provider-wide or network-backed search-picker work.
+- Architecture/data flow: preserves current renderer -> IPC/runtime mutation boundaries, but must route rows with parseable GitHub slugs through `updateIssueBySlug` so project/custom-source issues mutate the issue's own repository rather than the selected worktree repo.
+- API feasibility: path-based mutations already use the supported `gh issue close --duplicate-of` CLI path; slug-addressed mutations need the same CLI close/reopen treatment instead of REST `duplicate_of`.
+- Failure modes covered:
+  - Invalid duplicate targets stay local and do not mutate.
+  - Failed mutations revert optimistic state using the existing request id guard.
+  - Runtime/SSH remains on the existing serializable RPC method.
+  - Unsupported duplicate API shape is avoided by keeping duplicate close on `gh issue close --duplicate-of`.
+  - Rows filtered by open/closed status do not rely solely on optimistic patching; the relevant work-items cache must be invalidated/refetched after success.
+- Test coverage required:
+  - Unit tests for close update payloads and duplicate validation.
+  - Main-process tests for both `updateIssue` and `updateIssueBySlug` close/reopen command generation.
+  - Renderer routing tests for slug-addressed versus repo-path-addressed issue rows.
+  - Cache invalidation/refetch coverage for status-filtered Tasks lists.
+  - Existing status draft tests for optimistic reconciliation.
+  - Electron screenshots for menu, duplicate validation, closed styling, and adjacent header smoke.
+- Performance/blast radius: no material concern; one extra tiny model import and no new polling/IPC.
+- UI quality bar: compact GitHub-like action menu, token-based non-destructive closed styling, no clipping or overlap.
+- Required review screenshots:
+  1. Status popover with close reasons.
+  2. Duplicate second-step picker with search and issue candidates.
+  3. Non-red closed status pill.
+  4. Tasks header/search smoke.
+- Residual risks:
+  - Duplicate target search is limited to loaded Tasks cache candidates, with exact-number fallback for unloaded same-repository issues.
+  - Other open Orca windows may show stale status until their normal GitHub Tasks data refresh runs.

+# Terminal Scroll Intent Architecture
+
+## Problem
+
+Terminal panes can jump or jitter when a user switches workspaces while a TUI
+pane is scrolled near, but not exactly at, the bottom. The most visible case is a
+Codex-style alternate-screen TUI in a split pane:
+
+1. The user scrolls slightly up from the bottom.
+2. The user switches to another workspace.
+3. The user switches back.
+4. The terminal sometimes jumps to the top, jumps to the bottom, flashes at a
+   wrong position, or restores an older viewport.
+
+The current code tries to repair the viewport after layout, fit, split
+reparenting, hidden-output replay, and visibility resume. Those repairs compete
+with each other because none of them owns the user's scroll intent. A delayed
+restore can replay an old state after the user has already scrolled, while a
+follow-output path can force the bottom even when the user is reading scrollback.
+
+## Reference Investigation Summary
+
+The useful reference pattern is not a timer-based restore loop. It is an
+explicit pinned-to-bottom model owned by the terminal frontend:
+
+- The frontend stores bottom-following state separately from xterm's transient
+  `viewportY`.
+- `xterm.onScroll` is not used as user intent. In xterm, that event can be
+  content-driven and can briefly report bottom during fast output or layout work.
+- User wheel and keyboard scroll commands update the intent.
+- `scrollToBottom()` is an explicit command that sets the intent back to
+  follow-output.
+- Every write snapshots the intent before writing. If the terminal was following
+  output, it scrolls to bottom after the write. If the user was pinned to a
+  viewport, it preserves the prior viewport line.
+- Fit/resize uses the same rule: follow bottom if explicitly pinned, otherwise
+  preserve the current viewport.
+- Alternate-screen state is tracked from `buffer.active.type`, but it is not a
+  reason to infer user scroll intent from `onScroll`.
+
+The reference implementation also patches private xterm internals to disable
+xterm's implicit scroll-to-bottom behavior and call the original bottom-scroll
+only from explicit owner paths. That gives a clean ownership boundary, but it is
+an escalation point for Orca because private internals increase xterm upgrade
+risk.
+
+## Current Orca Risk Points
+
+The current Orca branch already has several independent scroll actors:
+
+- `src/renderer/src/lib/pane-manager/pane-scroll.ts` captures `viewportY`,
+  `baseY`, bottom state, and sometimes a marker, then restores using immediate,
+  rAF, and timeout paths.
+- `src/renderer/src/lib/pane-manager/pane-tree-ops.ts` captures and restores
+  scroll around `safeFit()`.
+- `src/renderer/src/lib/pane-manager/pane-split-scroll.ts` schedules split
+  reparent restores across rAF and timeout phases.
+- `src/renderer/src/components/terminal-pane/use-terminal-scroll-visibility-memory.ts`
+  listens to `terminal.onScroll` and stores snapshots while visible.
+- `src/renderer/src/components/terminal-pane/pty-connection.ts` writes PTY output
+  through foreground, background, hidden-output skip, snapshot replay, and
+  restore paths.
+- `src/renderer/src/lib/pane-manager/pane-terminal-output-scheduler.ts` can
+  write immediately, enqueue foreground writes, coalesce synchronized output, or
+  drain hidden/background chunks later.
+
+The biggest architectural mismatch is the visibility memory hook's use of
+`terminal.onScroll` as a snapshot trigger. That event is not a reliable user
+scroll signal. During workspace switching, output parsing, hidden replay, or fit
+can make it persist transient positions that later appear as "older position"
+restores.
+
+## Design Goal
+
+Make terminal viewport movement a result of explicit scroll intent, not a side
+effect of visibility, output, or layout timing.
+
+The terminal should have one active scroll intent per pane:
+
+- `followOutput`: the terminal is logically pinned to the live output bottom.
+  New output, explicit focus-follow requests, and fits may keep it at bottom.
+- `pinnedViewport`: the user is reading a specific viewport. New output,
+  workspace switches, hidden-output replay, and fits must not move the viewport
+  except when scrollback pruning or buffer replacement makes the exact line
+  impossible.
+
+## State Model
+
+Add a focused module, for example:
+
+`src/renderer/src/lib/pane-manager/terminal-scroll-intent.ts`
+
+Suggested state:
+
+```ts
+export type TerminalScrollIntentKind = 'followOutput' | 'pinnedViewport'
+
+export type TerminalScrollIntent = {
+  kind: TerminalScrollIntentKind
+  bufferType: 'normal' | 'alternate'
+  viewportY: number
+  baseY: number
+  capturedAt: number
+}
+```
+
+The state should be keyed by the live `Terminal` or by pane leaf identity where
+it needs to survive pane replacement. For normal workspace switches that keep
+the same xterm instance, the live terminal-keyed state should be authoritative.
+
+## Intent Transitions
+
+Only these events should change scroll intent:
+
+- User wheel scrolls upward: set `pinnedViewport` immediately before xterm write
+  callbacks or rAF can pull the viewport back down.
+- User wheel scrolls downward: after xterm applies the scroll, recompute whether
+  the viewport reached bottom. If yes, set `followOutput`; otherwise keep
+  `pinnedViewport`.
+- User keyboard scroll commands: apply the same rules as wheel.
+- Explicit `scrollToBottom()`, "follow output", or focus command with
+  follow-output semantics: set `followOutput`.
+- Programmatic `scrollToTop()` or page/line scroll commands: set
+  `pinnedViewport`, unless the resulting viewport is bottom.
+- Buffer change to alternate screen: record `bufferType`, but do not infer
+  follow-output from `onScroll`.
+- Buffer return to normal screen: recompute from current viewport only if no
+  stronger user intent exists for the normal buffer.
+- Scrollback prune: clamp a pinned viewport to the nearest valid line without
+  changing intent.
+- Terminal remount/replay: restore from durable fallback only if the live xterm
+  instance was actually replaced.
+
+Do not use xterm `onScroll` to set intent. It may still be useful as a passive
+diagnostic signal, but it should not persist authoritative scroll state.
+
+## Write Contract
+
+All PTY output that reaches xterm should pass through one wrapper that enforces
+intent around the actual `terminal.write` call.
+
+Suggested owner:
+
+`src/renderer/src/lib/pane-manager/pane-terminal-output-scheduler.ts`
+
+Contract:
+
+1. Capture intent and current `viewportY` before the write is scheduled.
+2. Execute the write through the existing foreground/background/coalescing path.
+3. After the write has parsed enough for xterm buffer state to be meaningful:
+   - If intent is `followOutput`, scroll to bottom.
+   - If intent is `pinnedViewport`, clamp and restore the saved viewport line.
+4. Do not schedule multi-frame retries for normal output. A single post-write
+   enforcement point should be enough for standard writes.
+
+For foreground synchronized-output holds, the enforcement point should run after
+the held/coalesced frame is released, not for each partial cursor-hide chunk.
+
+For background writes, preserve `pinnedViewport` if the pane is hidden or
+inactive. Hidden output should not silently repin the terminal.
+
+## Fit And Resize Contract
+
+`safeFit()` should stop using generic delayed scroll restoration as its normal
+behavior.
+
+New rule:
+
+1. If dimensions do not change, do nothing.
+2. Before fit, capture current intent and viewport.
+3. Fit.
+4. If intent is `followOutput`, scroll to bottom.
+5. If intent is `pinnedViewport`, restore the saved viewport line clamped to the
+   new `baseY`.
+
+Avoid fitting hidden or zero-geometry panes. Existing geometry guards should
+remain because fitting to transient workspace-switch geometry can send bad sizes
+to the PTY and trigger TUI redraw churn.
+
+## Visibility And Workspace Switch Contract
+
+Workspace switching should not be a scroll operation.
+
+On hide:
+
+- Capture the current intent once.
+- Do not run scroll restore.
+- Do not update intent from `onScroll`.
+- Continue hidden-output throttling/snapshot behavior as today.
+
+On show:
+
+- Reattach or refresh renderer resources as needed.
+- Flush only the bounded amount of hidden output required for the active pane.
+- Apply intent once after the visible output catch-up:
+  - `followOutput` goes to bottom.
+  - `pinnedViewport` stays pinned.
+- Do not run repeated rAF/timeout scroll restores.
+
+If the underlying terminal instance was replaced, use durable fallback state.
+If the instance stayed alive, its live scroll intent is authoritative.
+
+## Hidden Output And Snapshot Replay
+
+Hidden-output snapshot replay is a true fallback path because it clears and
+reconstructs xterm content. It needs scroll handling, but it should still obey
+intent:
+
+- Before snapshot replay, capture intent and viewport.
+- Replay serialized content.
+- Fit only if needed and only with valid visible geometry.
+- Reapply the captured intent once:
+  - `followOutput`: bottom.
+  - `pinnedViewport`: previous viewport line, clamped.
+- Do not let replay set follow-output just because the replayed buffer ends at
+  bottom.
+
+If hidden output arrives while the user is pinned, background catch-up should not
+move the visible viewport on activation.
+
+## Split Reparenting
+
+DOM reparenting can reset browser scroll state and WebGL resources. This is a
+legitimate place for a fallback restore, but it should be scoped:
+
+- Capture intent before reparent.
+- Reparent.
+- Reattach renderer if required.
+- Apply intent once after DOM settles.
+- Avoid restoring alternate-screen scrollback, because alternate screen has no
+  normal scrollback and a TUI owns its cursor.
+
+The current split-specific rAF/timer code should become a local fallback for DOM
+reparenting only, not a general model copied into workspace switching.
+
+## Performance Constraints
+
+The design must preserve Orca's terminal performance priorities:
+
+- Do not keep all hidden terminals hot-rendering.
+- Keep PTY/session/xterm state warm when feasible, but suspend hidden rendering
+  work and throttle hidden output as today.
+- Avoid per-output layout reads. Intent enforcement should read xterm buffer
+  fields, not DOM geometry.
+- Avoid multi-frame restore loops. They cause visible jitter and keep the
+  renderer busy after activation.
+- Keep active-pane hidden-output catch-up bounded. Inactive visible split panes
+  can catch up over later frames.
+- Do not send resize/SIGWINCH unless dimensions actually changed and the
+  renderer is the authoritative size owner.
+
+The intended steady-state cost is one small buffer-state capture per xterm write
+batch, not per byte and not per animation frame.
+
+## Implementation Plan
+
+1. Add `terminal-scroll-intent.ts`.
+   - Track `followOutput` vs `pinnedViewport`.
+   - Provide helpers for user scroll, explicit bottom, write capture, fit
+     capture, and intent enforcement.
+
+2. Replace visibility-memory `onScroll` ownership.
+   - Remove authoritative snapshot updates from `terminal.onScroll`.
+   - Add capture-phase wheel listeners and keyboard scroll command hooks.
+   - Keep `onScroll` only for diagnostics if needed.
+
+3. Route explicit scroll commands through intent helpers.
+   - `scrollToBottom()` sets `followOutput`.
+   - `scrollToTop()`, page up, and line up set `pinnedViewport`.
+   - Downward commands recompute after the command.
+
+4. Wrap output writes.
+   - Add an intent-aware writer boundary in the output scheduler or in a narrow
+     wrapper used by the scheduler.
+   - Ensure foreground coalescing applies intent after the coalesced frame.
+   - Ensure background drains preserve pinned viewports.
+
+5. Convert `safeFit()` to intent-aware fit.
+   - Capture intent before fit.
+   - Apply once after fit.
+   - Remove generic deferred scroll restore from normal fit.
+
+6. Limit restore fallbacks.
+   - Keep fallback restore only for true remount/replay/reparent cases.
+   - Remove workspace-switch rAF/timeout restore loops once intent enforcement is
+     in place.
+
+7. Add focused tests.
+   - User scroll up sets `pinnedViewport`.
+   - Output while pinned preserves viewport.
+   - Output while following scrolls to bottom.
+   - Fit while pinned preserves viewport.
+   - Fit while following stays at bottom.
+   - Hidden-output replay while pinned does not repin.
+   - Workspace hide/show does not change intent.
+   - `onScroll` does not mutate intent.
+
+8. Add an E2E reproduction.
+   - Use the existing `scroll-primary` and `scroll-secondary` worktrees.
+   - Top pane in `scroll-primary` contains the TUI with enough scrollback.
+   - Scroll slightly above bottom, switch to `scroll-secondary`, then switch back.
+   - Assert the terminal remains within a small viewport tolerance and does not
+     visit top/bottom during the transition.
+
+## Acceptance Criteria
+
+- Switching away and back does not move a pinned TUI viewport.
+- No visible flash to top or bottom during activation.
+- Scrolling all the way to bottom re-enables follow-output and does not later
+  restore an older pinned position.
+- Hidden output in inactive workspaces does not change visible scroll position
+  until the user explicitly follows output or reaches bottom.
+- Alternate-screen TUIs do not receive extra restore/fill behavior that shifts
+  their cursor or scroll region.
+- The active pane remains responsive during heavy hidden-output catch-up.
+
+## Open Decisions
+
+- Whether Orca should patch private xterm bottom-scroll internals. The reference
+  pattern does this for strict ownership, but Orca should first try public API
+  enforcement at write/fit boundaries and only escalate if xterm continues to
+  auto-follow independently.
+- Whether scroll intent should be stored only by live `Terminal` instance or also
+  mirrored by leaf ID for remount fallback. The initial implementation should
+  use live instance state plus a leaf-keyed fallback for true replacement.
+- Whether alternate screen needs a separate intent record from normal screen.
+  The first version can use one record with `bufferType`; a separate normal vs
+  alternate record is justified only if testing shows mode switches overwrite
+  user intent.
