+# Implementation Plan: Archive progress feedback
+
+## Overview
+
+Add one persistent loading toast around every user-initiated archive request,
+then prove its desktop and phone presentation with the existing deferred
+archive scenarios. The shared action hook changes first so all task surfaces
+receive the behavior; the `/tasks` listing then joins that boundary, and the
+same end-to-end flows capture review screenshots.
+
+## Scope
+
+### In scope
+
+- Localized `Archiving in progress` feedback in the existing bottom-right toast
+  stack for single and bulk user archive actions.
+- One progress toast per operation or bulk batch, retained until the last
+  archive request settles and dismissed on either success or failure.
+- The `/tasks` listing and every archive surface already routed through
+  `useTaskActions`.
+- Desktop and phone Playwright evidence plus PR-ready screenshots of the
+  controlled pending state.
+
+### Out of scope
+
+- Archive API, persistence, permissions, confirmation, cascade, navigation,
+  recovery, success, or failure semantics.
+- Delete, unarchive, API, CLI, MCP, agent-driven, and other programmatic archive
+  operations.
+- A new toast component, placement system, setting, feature flag, or mobile
+  navigation composition.
+
+## Technical approach
+
+### Shared archive action feedback
+
+Add a private progress-toast lifecycle inside
+`apps/web/hooks/use-task-actions.ts`. `archiveTaskById` creates the existing
+non-expiring `loading` toast before invoking `archiveTask`, tracks concurrent
+requests from the same hook instance, and dismisses it in `finally` only after
+the final request settles. Keep outcome feedback with the current coordinator
+and surface handlers.
+
+Update `apps/web/app/tasks/tasks-page-client.tsx` to call
+`archiveTaskById` instead of importing the transport function directly. Preserve
+that listing's current refresh and terminal toast behavior.
+
+Add `tasks:archivingInProgress` to English, pseudo, Portuguese, Simplified
+Chinese, and generated Traditional Chinese catalogs. Do not place translated
+copy at module scope.
+
+### Rendered verification and PR evidence
+
+Extend `apps/web/e2e/tests/task/sidebar-immediate-archive-helpers.ts` while its
+archive route is deliberately held. Assert the loading toast, spinner, polite
+live region, bottom-right placement, and later removal before checking the
+existing success and failure outcomes. Reuse the helper from the current
+desktop and `mobile-chrome` specs.
+
+Pass `prCapture` from both specs and capture one full-page pending-state image
+per viewport. `CAPTURE_PR_ASSETS=1` writes both screenshots and their captions
+to `apps/web/.pr-assets/manifest.json` for the PR workflow.
+
+Nearest phone exemplar: the existing `ToastProvider` stack itself. It supplies
+the fixed, status-bar-aware placement, live announcement, and non-blocking
+presentation. This change adds a state to that shared surface, with no new
+phone action, navigation, scroll owner, or touch target.

+| |           progress       | |
+| +--------------------------+ |
++------------------------------+
+  fixed above app status bar; viewport-contained
+```
+
+Structural requirements: the toast is non-blocking, localized, announced by
+the existing polite live region, contains a visible loading indicator, and
+does not time out while the request is pending. One operation or bulk batch
+shows one toast. Spacing and line wrapping are illustrative and continue to use
+the existing toast component. These previews map to
+`AC-TASKS-REMOVAL-NAVIGATION-004.1` through `.3`.
+
+## Tests
+
+- `apps/web/hooks/use-task-actions.test.ts`: a deferred archive creates the
+  localized loading toast before settlement, does not dismiss it early,
+  dismisses on resolve and reject, and coalesces concurrent requests from one
+  hook instance.
+- Existing terminal success and failure assertions remain unchanged, proving
+  the progress state adds no second outcome notification.
+
+## E2E tests
+
+- `apps/web/e2e/tests/task/sidebar-immediate-archive.spec.ts` covers
+  `AC-TASKS-REMOVAL-NAVIGATION-004.1` through `.3` on desktop and captures
+  `UI-01`.
+- `apps/web/e2e/tests/task/mobile-sidebar-immediate-archive.spec.ts` covers the
+  same criteria in the `mobile-chrome` project, verifies viewport containment,
+  and captures `UI-02`.
+
+## Work orders
+
+- [x] [Task 01: Show archive progress feedback](task-01-show-archive-progress.md)
+
+## Verification results
+
+- Focused `useTaskActions` unit suite passed with resolve, reject, and
+  concurrent-request coverage.
+- Web typecheck and the complete i18n catalog checks passed.
+- Desktop Chromium and phone `mobile-chrome` archive scenarios passed and
+  produced reviewed, compressed PR screenshots.
+- Specification, public-doc, and diff validation passed.
+
+## Risks
+
+- Bulk archives can accidentally create one toast per task unless the shared
+  action hook counts concurrent requests from the same operation.
+- A missing `finally` dismissal can leave a permanent loading toast after a
+  rejection or navigation transition.
+- The fixed-width desktop toast must stay inside the configured phone viewport;
+  rendered geometry and horizontal-overflow checks guard that contract.

+# Task 01: Show archive progress feedback
+
+## Summary
+
+Wrap user-initiated archive requests in one localized, non-expiring loading
+toast and route the remaining `/tasks` archive action through the shared hook.
+Prove the pending, success, failure, desktop, and phone states, then capture the
+two pending views for the pull request.
+
+## In scope
+
+- Shared archive progress-toast lifecycle and concurrent-request coalescing.
+- `/tasks` listing adoption of the shared archive action.
+- Shipped locale catalogs.
+- Unit and focused desktop/mobile Playwright coverage.
+- PR asset capture for both viewports.
+
+## Out of scope
+
+- Changes to archive transport, confirmation, cascade, navigation, recovery,
+  persistence, or permissions.
+- Loading feedback for delete, unarchive, or programmatic archive callers.
+- New toast or mobile navigation primitives.
+
+## Acceptance
+
+- A single or bulk archive shows one localized loading toast before its request
+  settles; concurrent tasks in the same bulk action do not create a toast pile.
+- The toast remains present without a timeout while pending, then is dismissed
+  on resolve or reject while existing terminal feedback remains unchanged.
+- Desktop and phone tests prove the visible spinner, polite announcement,
+  bottom-right viewport placement, cancellation behavior, cleanup, and PR
+  screenshots.

+## Dependencies
+
+None. The existing task-removal coordinator, toast loading variant, deferred

+
+## Risks
+
+- Hook instances are surface-local, so the counter must coalesce only requests
+  started by one operation without suppressing a separate concurrent action.
+- Toast cleanup must run for both fulfilled and rejected archive promises.
+- Phone capture must occur before reopening the task picker so the screenshot
+  shows the global toast in the normal task surface.
+
+## Parallelism
+
+`sequential`
+
+## Inputs
+
+- `REQ-TASKS-REMOVAL-NAVIGATION-004` and the archive progress section of the
+  task-removal system design.
+- Existing `useTaskActions`, `ToastProvider`, archive-removal tests, and
+  `PrAssetCapture` patterns.
+- The existing `ToastProvider` phone stack is the nearest mobile exemplar; its
+  status-bar-aware fixed placement and polite live region remain unchanged.
+
+## Results
+
+- Added a reference-counted loading-toast lifecycle to the shared archive
+  action and routed the tasks listing through it.
+- Added complete locale coverage and documented the visible pending state in
+  the public task lifecycle guide.
+- Added unit and desktop/phone Playwright coverage for cancellation, pending,
+  success, failure, accessibility, placement, and concurrent archives.
+- Captured and reviewed fresh desktop and phone screenshots for the pull
+  request.

 Archive records the task as archived and removes it from active views immediately. Runtime stopping and physical cleanup then run in the background with a 60-second timeout. Cleanup is best-effort: a stop or deletion failure is logged and does not undo the archive, and Kandev preserves a runtime or environment when a nonterminal session cannot be stopped. Shared inherited environments and borrowed worktrees are also preserved while another active task still uses them.

+`useTaskActions.archiveTaskById` is the common user-action mutation boundary
+for the board, preview, sidebar, task switcher, task detail, command, message,
+and bulk archive paths. Keep the low-level `archiveTask` API function
+transport-only so API helpers, tests, and non-UI callers do not create browser
+feedback. The `/tasks` listing is the only current user-facing caller that
+invokes `archiveTask` directly; route that action through `useTaskActions` so it
+shares the same progress lifecycle without changing its existing refresh,
+success, or failure handling.
+
+The archive action hook owns one loading-toast record with an in-flight request
+count. The first archive request creates a localized `loading` toast through
+`ToastProvider`; concurrent requests started by the same bulk operation reuse
+that toast and increment the count. Every request decrements the count in a
+`finally` path, and the last settlement dismisses the toast. Independent
+operations started from separate surfaces retain separate feedback, matching
+the existing surface-local concurrency contract.
+
+The loading toast uses the existing non-expiring loading variant, spinner, and

+progress` in the English catalog and equivalent copy in every shipped locale.
+It adds no action, drawer, scroll owner, or focus target. Desktop and phone use
+the same toast component; the phone check verifies that the fixed toast remains
+inside the viewport and above the existing app status bar.
+
+The progress lifetime is scoped to the archive mutation request. On settlement
