Sending and stopping from the composer use only ACP session/prompt and session/cancel. ACP text, thinking, tools, permissions, plans, attachments, generated files, generated images, and errors continue to render through the ACP timeline without the legacy ChatMessage or Execution Graph pipeline. Session discovery, sidebar ordering and attention, title hydration, history supplementation, selection, deletion, and rename continue to behave as before. Catalog reconciliation repairs removed selections atomically, resets suppression and timestamp fences across Gateway generations, withholds a selected persisted session until its workspace summary settles, and never overwrites a newer local catalog or selection mutation with the delayed snapshot. A failed hard delete keeps the session and confirmation dialog intact; navigation and dialog closure happen only after host-confirmed deletion. Bulk deletion repairs a deleted current selection atomically with the remaining catalog, preferring a valid non-cron/non-channel session or creating an agent-local placeholder. Asynchronous OpenClaw image-generation completions continue to appear when accepted by the existing bounded ACP compatibility checks.	fast comms e2e	renderer-main-boundary backend-communication-boundary api-client-transport-policy host-api-fallback-policy host-events-fallback-policy gateway-readiness-policy acp-chat-state-and-history acp-compatibility-content-safety attachment-access-safety diagnostics-trace-safety session-workspace-authority sidebar-session-attention-authority tool-derived-file-safety ui-i18n-design-tokens comms-regression docs-sync	pnpm run typecheck pnpm exec vitest run tests/unit/acp-host-contract.test.ts tests/unit/acp-chat-service.test.ts tests/unit/acp-reducer.test.ts tests/unit/acp-chat-store.test.ts tests/unit/acp-chat-components.test.tsx tests/unit/chat-acp-page.test.tsx tests/unit/chat-toolbar.test.tsx pnpm exec vitest run tests/unit/acp-image-generation-compat.test.ts tests/unit/session-catalog.test.ts tests/unit/chat-load-sessions-startup.test.ts tests/unit/chat-session-management.test.ts tests/unit/chat-session-selection.test.ts tests/unit/chat-store-session-label-fetch.test.ts tests/unit/sidebar-session-buckets.test.ts pnpm exec vitest run tests/unit/host-api-facade.test.ts tests/unit/host-events.test.ts tests/unit/host-services.test.ts tests/unit/gateway-event-dispatch.test.ts pnpm exec vitest run tests/unit/gateway-manager-diagnostics.test.ts tests/unit/gateway-ws-trace.test.ts tests/unit/stores.test.ts pnpm exec vitest run tests/unit/generated-files.test.ts tests/unit/file-preview-body.test.tsx tests/unit/artifact-panel.test.tsx tests/unit/openclaw-file-activities.test.ts tests/unit/i18n-locale-parity.test.ts pnpm exec playwright test tests/e2e/chat-acp-inline-timeline.spec.ts tests/e2e/chat-acp-attachments.spec.ts tests/e2e/chat-run-state-events.spec.ts tests/e2e/chat-acp-process-timeline.spec.ts tests/e2e/chat-sidebar-session-attention.spec.ts pnpm run comms:replay pnpm run comms:compare pnpm run lint:check pnpm run build:vite pnpm harness validate --spec harness/specs/tasks/remove-pre-acp-chat.md pnpm run harness:ci git diff --check	ACP session/load replay is the only normal Chat history render path; no Gateway Chat history, transcript reconstruction, legacy message array, or persisted parallel replay ledger renders ordinary Chat turns. ACP session/prompt and session/cancel are the only active composer send and stop paths; ACP permission responses remain a separate protocol action. Legacy ChatMessage, Execution Graph, task visualization, RawMessage rendering helpers, and useChatStore send/runtime state and actions are removed from production code and their legacy-only tests are deleted or replaced with ACP assertions. ACP-owned in-memory prompt state, including sending, cancelling, optimistic user segments, retained live prompt snapshots, and generation guards, remains intact. gateway:chat-message and chat:runtime-event contracts, Main forwarding, and Renderer subscriptions remain only where required for bounded ACP image-generation completion compatibility; they do not feed ordinary messages, history, composer state, tool state, task visualization, or session run state. Existing image-generation compatibility continues to require matching ACP session, generation, recent image_generate context, trusted completion evidence, deduplication, and stale-result rejection. Session catalog, sidebar and attention state, ACP history supplements, automatic title hydration, session selection, hard delete, and rename behavior remain supported without depending on removed legacy message or runtime state. Session deletion or hiding never leaves a dangling current selection; fallback selection follows the normal non-cron/non-channel policy or creates a fresh agent-local placeholder. Single and bulk deletion use the same current-selection repair policy and never select a cron/channel survivor implicitly or leave the absent default key selected. Selected persisted sessions with missing workspace identity are not published to ACP consumers before batched summary hydration settles, and stale summaries remain fenced by Gateway generation, session incarnation, and a local session catalog/selection mutation revision. The unreachable chat media-send shared/Main/Renderer contract is removed; ACP load, prompt, cancel, and permission operations remain the exact typed Chat host actions. The unused standalone Gateway client and Chat-history-only RPC backpressure layer are removed; typed generic Gateway RPC validates the same method and timeout inputs before delegating directly to GatewayManager.rpc. Generic Gateway RPC diagnostics and proxy tests use non-Chat methods; one Electron E2E assertion prevents ordinary Chat from resurrecting a chat.history call. No OpenClaw source, installed package source, bundled OpenClaw distribution, or OpenClaw patch is modified. Typecheck, focused ACP and host tests, relevant ACP Electron E2E, communication regression checks, task validation, and harness CI pass.	required true

Scope

Delete the pre-ACP Chat implementation after separating the session catalog and session-management responsibilities that are still consumed by ACP Chat. Remove legacy renderer history reduction, Gateway send orchestration, runtime send state, Execution Graph/task derivation, and their dead contracts, services, localization, and tests.

Keep the ACP timeline and composer as the sole normal Chat implementation. Preserve only the explicitly bounded Gateway-event bridge needed to project asynchronous image-generation completion evidence into the ACP timeline.

Preserved Boundaries

• ACP session/load, session/prompt, session/cancel, session/update, and session/request_permission retain their existing Main/Renderer ownership and generation guards.
• The existing transcript-derived ACP supplements remain bounded to approved generated-media and attachment content plus metadata-only timing; they do not become a second ordinary history path.
• Session catalog, sidebar attention, workspace binding, title hydration, selection, deletion, and rename remain independent of legacy message rendering and runtime send state.

Out Of Scope

• Modifying OpenClaw source, package contents, or bundled runtime behavior.
• Replacing ACP replay with Gateway Chat history or broad transcript reconstruction.
• Removing or widening the bounded ACP image-generation completion compatibility path.
• Redesigning the ACP timeline, composer, sidebar, workspace, attachment, permission, or file-activity experiences.
