Summary

A new task's opening prompt is now either sent or back in the composer. It is never left in the transcript as a paused "not sent" row with Retry, Cancel and Edit controls. This revises chat.subscribe@1.15 from #2071, which has not been released.

Protocol

  • The delivery states are pending | preparing | started | withdrawn, replacing paused and cancelled.
    • withdrawn carries code, reason, missingHashes, the prompt to hand back (restore), and whether a composer already has it (restoreClaimed).
  • The client actions messageDeliveryEdit, messageDeliveryRetry and messageDeliveryCancel are removed.
    • messageDeliveryRestored { messageId, expectedRevision } is added. A client sends it once a composer holds the prompt.
    • expectedRevision is an upper bound, so an acknowledgement of an earlier withdrawn revision still counts.
  • Chat-sync 1.6 keeps the providerHistory: "excluded" marker but drops its reader floor. An older reader renders the row as the ordinary user message it is. The floor locked older apps out of a chat for the whole of its setup.

GUI

  • While the opening is unresolved, its row shows "Sending" or "Setting up" and offers Copy only.
  • When the host withdraws it, the row leaves the transcript at once. Every local copy of the message stands aside in the same update, and the host's restore goes back into the composer. If the user has started a new draft, the restored prompt goes first and the draft follows it. The client then acknowledges the restore.
  • If the acknowledgement cannot be sent, it stays owed across reconnects. It is also mirrored to device storage, so a reload before the host answers resends it instead of merging the prompt a second time.
  • The initial-chat handoff never resends a message the delivery view names. The queue reconciler's recovery passes never restore or report that message on absence.

The host half is traycerai/traycer-internal#5825. The design and the older-client contract are recorded in the "Accepted messages belong to the conversation" epic artifact.

Revises #2071 (unreleased chat.subscribe@1.15).

Checklist

  • Pre-commit static checks pass (pre-commit run --all-files for an explicit full-repo run)
  • Separate CI test checks pass
  • Tests added/updated where it makes sense
  • Commits are signed off (git commit -s) per the DCO

Revises the unreleased chat.subscribe@1.15 from #2071. The delivery states
are pending | preparing | started | withdrawn; paused and cancelled are
gone, and with them the Retry, Cancel and Edit controls on a transcript row.
A withdrawn record carries the prompt to hand back, and the client
acknowledges with messageDeliveryRestored { messageId, expectedRevision },
an upper bound, so an earlier withdrawn revision still counts.

GUI: while the opening is unresolved its row reads "Sending" or "Setting
up" and offers Copy only. On withdrawal the row leaves the transcript, every
local copy stands aside in the same update, the restored prompt goes ahead of
any draft, and the acknowledgement stays owed across reconnects and is
mirrored per chat in device storage so a reload resends it instead of
merging the prompt twice. The initial-chat handoff never resends a message
the delivery view names; the queue reconciler never restores or reports one
on absence.

Chat-sync 1.6 keeps the providerHistory: "excluded" marker but drops its
reader floor, which walled older apps out of a chat for its whole setup.

Host half: traycerai/traycer-internal#5825.

Summary by CodeRabbit

  • New Features

    • Withdrawn opening messages can be restored to the composer while preserving eligible drafts and attachments.
    • Restoration status persists across reloads and is acknowledged when the session is ready.
    • Chat handoffs and message delivery reconcile more reliably, reducing duplicate or prematurely removed messages.
  • Improvements

    • Sending states now clearly show “Sending” or “Setting up.”
    • While pending or preparing, editing and deletion are unavailable, while copying remains available.
    • Edit actions use consistent “Send” and “Send edit” labels.

Walkthrough

This change replaces client-controlled delivery edits, retries, and cancellations with host-controlled withdrawal and restoration. It updates protocol schemas, chat reconciliation, acknowledgement persistence, composer restoration, rendered-message filtering, and message actions.

Changes

Message delivery protocol

Layer / File(s) Summary
Delivery contract and compatibility
protocol/src/host/agent/gui/*, protocol/src/persistence/chat-sync/*
Delivery now uses a withdrawn phase with restore content and revision data. The client sends messageDeliveryRestored instead of delivery edit, retry, and cancel actions. Older chat-sync readers no longer require a reader floor for excluded provider-history rows.

Withdrawal reconciliation

Layer / File(s) Summary
Delivery-aware session reconciliation
clients/gui-app/src/stores/chats/chat-session-store.ts, clients/gui-app/src/stores/chats/chat-queue-reconciler.ts
The session store removes local copies of withdrawn openings and preserves message IDs through recovery. Queue reconciliation waits while the host delivery view owns a message.
Rendered-message projection
clients/gui-app/src/stores/chats/rendered-messages.ts, clients/gui-app/src/components/epic-canvas/renderers/chat-tile.tsx, clients/gui-app/src/stores/chats/__tests__/rendered-messages.test.tsx
Rendered persisted, pending, and active user rows matching the withdrawn message ID are filtered out. Assistant and unrelated rows remain available.

Prompt restoration

Layer / File(s) Summary
Composer restoration and acknowledgement
clients/gui-app/src/hooks/chats/use-chat-message-delivery-restore-driver.ts, clients/gui-app/src/stores/chats/chat-session-store.ts, clients/gui-app/src/hooks/chats/use-chat-actions.ts
Eligible withdrawn prompts are restored into the composer. Restored content is merged with submittable drafts, and the store sends a revision-based acknowledgement.
Acknowledgement persistence and handoff handling
clients/gui-app/src/lib/chats/delivery-restore-ack-persistence.ts, clients/gui-app/src/lib/persist/keys.ts, clients/gui-app/src/lib/chats/next-handoff-transition.ts
Unacknowledged restoration records persist per chat. Reads and writes validate records and handle storage failures without throwing. Handoff transitions consume messages named by the delivery view.

Message actions and tests

Layer / File(s) Summary
Delivery-phase actions and inline editing
clients/gui-app/src/components/chat/chat-message.tsx, clients/gui-app/src/components/chat/chat-message-user-body.tsx, clients/gui-app/src/components/epic-canvas/renderers/use-chat-message-actions.ts, clients/gui-app/src/components/epic-canvas/renderers/chat-tile-session-state.ts
User actions now use deliveryPhase values of pending, preparing, or null. Pending and preparing rows show status text and disable modification actions. Standard edit and delete actions return after delivery starts.
Regression and integration coverage
clients/gui-app/src/**/__tests__/*, protocol/src/**/__tests__/*
Tests cover protocol compatibility, withdrawal filtering, queue settlement, restoration gates, draft merging, acknowledgement persistence, reload behavior, and updated action fixtures.

A rabbit saw a prompt withdraw,
Then tucked its words in drafts of straw.
The host sent one bright thank-you sign,
The queue kept every row in line.
“Pending paws, then ready feet!”
The composer made the tale complete.

The four reconnect and stop cases compare the failed-send restoration slot
with toEqual, and the slot now names the message it restores.

The retained user-message ids anchor record-less turn.stopped events to
a row. A withdrawn opening's row is hidden, but its id stayed in the set,
so a legacy chat's turn.stopped naming it (a stop in the old setup window,
migrated on upgrade) drew an orphan stopped row until the host's removal
landed. The withdrawn id is removed from the set in the same render.
