Naiyuan Qing 45dae3185f fix(issues): eliminate optimistic-update drag flicker (board, list, batch, WS) (#4415)
* fix(issues): stop kanban card snapping back on drag

A cross-column drag on a non-position-sorted board left the card in its
origin column for the whole request, then jumped to the target only when
the mutation settled — the "snaps back, then moves" glitch. Root cause was
three coupled choices in the optimistic path:

- board-view never updated local columns on drop for sortBy != "position"
  (onDragOver is a no-op there), so the card relied on the settle refetch
  to move across.
- useUpdateIssue invalidated the whole list on settle, replacing the column
  and re-landing the card even on success.
- patchIssueInBuckets appended a moved card to the column tail instead of
  its position slot, so any later cache refresh teleported it to the end.

Fixes:
- board-view: optimistically move the card into the target column on drop
  for the non-position path (insertIdByPosition), and reconcile local
  columns from the cache on settle for both paths (revert on error now that
  the list is no longer refetched).
- mutations: reconcile via onSuccess surgical patch of the returned entity;
  drop the list/detail invalidation from onSettled (aggregates still flush).
- cache-helpers: patchIssueInBuckets inserts the moved/reordered card at its
  position slot; a plain field update still keeps its slot.

Adds cache-helpers and drag-utils unit tests.

* fix(issues): patch My-Issues / Project board caches on move too

The drag fix made the board reconcile local columns from its feeding cache
on settle. The workspace board rides issueKeys.list (patched by onMutate),
but the My-Issues and Project boards ride the myList cache, which the
mutation did not patch — so a successful move snapped back on those boards.

useUpdateIssue now patches/snapshots/rolls back every bucketed list cache
(workspace list + myList), selected by the ListIssuesCache `byStatus` shape
so grouped (assignee) and flat (gantt) caches are skipped. Adds renderHook
regression tests covering both-cache optimistic move, both-cache rollback,
and no-list-invalidation-on-settle.

* fix(issues): drop redundant WS position->list invalidate

onIssueUpdated already surgically patches the non-filtered workspace board
via patchIssueInBuckets (cross-status move + same-column reorder). The extra
`if (position) invalidateQueries(list)` re-pulled the whole board on top of
that, re-introducing drag flicker through the echoed-back WS event. Removed.
Filtered myAll lists still invalidate (membership can change there) — the
client-side membership reconciliation for those is a separate follow-up.

* fix(issues): batch update patches myList + stops list refetch on settle

- onMutate now patches both issueKeys.list and the filtered issueKeys.myAll
  bucketed caches, so a batch edit on a My-Issues / Project board is
  optimistic too. Previously only the workspace board was patched, so batch
  edits on those boards relied entirely on the settle refetch.
- onSettled no longer invalidates issueKeys.list: the optimistic patch is a
  complete reconcile for these bucketed boards (batch changes status /
  priority / project, never a server-computed value), so a full-board
  refetch only re-introduced the flicker the single-issue path removed.
  Aggregate / grouped caches still refresh.

* fix(issues): list view optimistically moves row on non-position drag

The sortBy != "position" branch called onMoveIssue without moving the row in
local columns, so the row sat in its origin group for the whole request and
only jumped across on settle -- the same snap-back the board view had before
its fix. Now mirrors board-view: setColumns(insertIdByPosition) on drop so
the settle rebuild is a visual no-op.

* fix(issues): keep My-Issues/Project boards in place on non-membership WS change

onIssueUpdated now surgically patches the filtered myList (myAll) caches and
only invalidates them when the change can actually move an issue in/out of the
filter: an assignee change (covers My-Issues direct-assignee + the involves leg
+ actor panels) or a project change (Project board). A pure status / position /
priority / label change reconciles in place -- no refetch -- removing the last
drag flicker on filtered boards.

Uses the assignee_changed flag the server already sends on issue:updated
(surfaced on IssueUpdatedPayload + forwarded by the realtime dispatch); project
change is diffed client-side against the cached value. No predicate replication,
no backend change.

* fix(issues): add settle-lock to swimlane drag (no clobber mid-flight)

The swimlane drag had no settle window: the resync useEffect (and the issueMap
freeze) guarded only isDraggingRef, so a cache change landing after drop but
before the move settled could rebuild localCells out from under the optimistic
move. Adds isSettlingRef + settleVersion (mirroring board-view / list-view): the
lock is held from drop until onMoveIssue settles, then released, forcing a
single resync from the reconciled cache.

onMoveIssue now accepts the same optional onSettled callback board/list already
use; the parent handleMoveIssue supplies it.

* refactor(issues): extract shared useDragSettle hook for board + list

board-view and list-view carried byte-identical drag/settle scaffolding (the
local columns mirror, the dragging/settling locks, the post-move animation-frame
throttle, and the settle callback). That duplication is exactly what let
list-view silently drift earlier (it had lost the optimistic-move half of the
fix, and its position-branch settle callback omitted the settleVersion bump).
Extract the primitive into useDragSettle so both surfaces share one
implementation and can't drift again.

Behavior-preserving for board-view. For list-view the one intended alignment:
its position-branch failed move now reverts, gaining the settleVersion bump
board-view already had.

What is Multica?

Multica turns coding agents into real teammates. Assign issues to an agent like you'd assign to a colleague — they'll pick up the work, write code, report blockers, and update statuses autonomously.

No more copy-pasting prompts. No more babysitting runs. Your agents show up on the board, participate in conversations, and compound reusable skills over time. Think of it as open-source infrastructure for managed agents — vendor-neutral, self-hosted, and designed for human + AI teams. Works with Claude Code, Codex, GitHub Copilot CLI, OpenClaw, OpenCode, Hermes, Gemini, Pi, Cursor Agent, Kimi, Kiro CLI, and Qoder CLI.

For larger teams, Squads add a stable routing layer: assign work to a group led by an agent, and the leader delegates to the right member.

Multica board view

Why "Multica"?

Multica — Multiplexed Information and Computing Agent.

The name is a nod to Multics, the pioneering operating system of the 1960s that introduced time-sharing — letting multiple users share a single machine as if each had it to themselves. Unix was born as a deliberate simplification of Multics: one user, one task, one elegant philosophy.

We think the same inflection is happening again. For decades, software teams have been single-threaded — one engineer, one task, one context switch at a time. AI agents change that equation. Multica brings time-sharing back, but for an era where the "users" multiplexing the system are both humans and autonomous agents.

In Multica, agents are first-class teammates. They get assigned issues, report progress, raise blockers, and ship code — just like their human colleagues. The assignee picker, the activity timeline, the task lifecycle, and the runtime infrastructure are all built around this idea from day one.

Like Multics before it, the bet is on multiplexing: a small team shouldn't feel small. With the right system, two engineers and a fleet of agents can move like twenty.

Features

Multica manages the full agent lifecycle: from task assignment to execution monitoring to skill reuse.

  • Agents as Teammates — assign to an agent like you'd assign to a colleague. They have profiles, show up on the board, post comments, create issues, and report blockers proactively.
  • Squads — group agents (and humans) under a leader agent and assign work to the squad. The leader decides who should pick it up, so routing stays stable as the team grows. @FrontendTeam instead of @alice-or-bob-or-carol.
  • Autonomous Execution — set it and forget it. Full task lifecycle management (enqueue, claim, start, complete/fail) with real-time progress streaming via WebSocket.
  • Autopilots — schedule recurring work for agents. Cron triggers, webhooks, or manual runs — each autopilot creates the issue and routes it to an agent automatically, so daily standups, weekly reports, and periodic audits run themselves.
  • Reusable Skills — every solution becomes a reusable skill for the whole team. Deployments, migrations, code reviews — skills compound your team's capabilities over time.
  • Unified Runtimes — one dashboard for all your compute. Local daemons and cloud runtimes, auto-detection of available CLIs, real-time monitoring.
  • Multi-Workspace — organize work across teams with workspace-level isolation. Each workspace has its own agents, issues, and settings.

Quick Install

brew install multica-ai/tap/multica

Use brew upgrade multica-ai/tap/multica to keep the CLI current.

macOS / Linux (install script)

curl -fsSL https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.sh | bash

Use this if Homebrew is not available. The script installs the Multica CLI on macOS and Linux by using Homebrew when it is on PATH, otherwise it downloads the binary directly.

Windows (PowerShell)

irm https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.ps1 | iex

Then configure, authenticate, and start the daemon in one command:

multica setup          # Connect to Multica Cloud, log in, start daemon

Self-hosting? Add --with-server to deploy a full Multica server on your machine:

curl -fsSL https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.sh | bash -s -- --with-server
multica setup self-host

This pulls the official Multica images from GHCR (latest stable by default). Requires Docker. See the Self-Hosting Guide for details. If the selected GHCR tag has not been published yet, fall back to make selfhost-build from a checkout.


Getting Started

1. Set up and start the daemon

multica setup           # Configure, authenticate, and start the daemon

The daemon runs in the background and auto-detects agent CLIs (claude, codex, copilot, openclaw, opencode, hermes, gemini, pi, cursor-agent, kimi, kiro-cli, agy, qodercli) on your PATH.

2. Verify your runtime

Open your workspace in the Multica web app. Navigate to Settings → Runtimes — you should see your machine listed as an active Runtime.

What is a Runtime? A Runtime is a compute environment that can execute agent tasks. It can be your local machine (via the daemon) or a cloud instance. Each runtime reports which agent CLIs are available, so Multica knows where to route work.

3. Create an agent

Go to Settings → Agents and click New Agent. Pick the runtime you just connected and choose a provider (Claude Code, Codex, GitHub Copilot CLI, OpenClaw, OpenCode, Hermes, Gemini, Pi, Cursor Agent, Kimi, Kiro CLI, Antigravity, or Qoder CLI). Give your agent a name — this is how it will appear on the board, in comments, and in assignments.

4. Assign your first task

Create an issue from the board (or via multica issue create), then assign it to your new agent. The agent will automatically pick up the task, execute it on your runtime, and report progress — just like a human teammate.


CLI

The multica CLI connects your local machine to Multica — authenticate, manage workspaces, and run the agent daemon.
