+Workflow stage now shows short task summaries with pause, resume, and progress tied to live runs only; sidebar status never mirrors scripted or seeded runs (`demos[]` and `workflow/demo-step` removed). Factory workflows such as the delivery preset can be removed from the sidebar via Delete (confirm), not reset-only ([#1454](https://github.com/ThinkFlowLab/FlyBot/issues/1454)).

 1. Friends' Bots are not nodes. A `remote` Bot is refused by create, define and the matcher.
 2. The canvas and the run share one graph: nodes, edges and positions. A drag commits `workflow/graph`. Status highlighting reads that same graph. Replacing edges does not recompute who is already running.
-3. **A live run advances only when its ephemeral Bot replies, following the graph's edges in order.** That reply is the chat line. Nodes start only when their forward predecessors finish and edges reach them. `workflow/demo-step` exists for unit tests and scripted fixtures only; the browser client does not call it. A run does not create a schedule. `scheduleLabel` is display text. When the host can create Bots, starting a live run (`assign`, `run_workflow`, `ingest`) spawns one ephemeral Bot per node from that node's prompt, role, model and tools, sends it the step from the Main Bot, and removes every instance when the run finishes, fails for good, or is reset. A `failOnce` retry keeps them. They are hidden and left out of the sidebar. Loading the plugin does not spawn Bots for the seeded fixture. Loading is also the one moment a run the host left behind is noticed: a run still marked `running` is abandoned, so loading releases its instances and records the run as `failed`. Nothing resumes it. A run that already ended keeps its own status (#1388). A dispatch that does not land is not marked handed. The chat names the code, and the next hand-off tries that node again. It is not sent twice in the same hand-off. A reply that says `could not answer your message` or `model call failed` fails that node and does not start its successor. A 429 or rate-limit mention in any other reply does not.
-4. Each workflow keeps a FIFO queue and up to `maxConcurrent` live runs (default 2, an integer from 1 to 8 on the record or via `workflow/concurrency`). The host runs at most 6 live runs at once. A task that does not fit is enqueued. When a run finishes, every workflow with a free slot is drained, oldest enqueue first, until the host cap. A new assign on a workflow that already has a queue waits behind it. A task does not replace a running run or release that run's Bots. An old store run is a demo unless it is still `running` and has ephemeral Bot ids. History records a finished or failed run only. Lowering the cap does not stop a run that has already started. Assigning `{ botId }` claims the card for that local Bot and does not enqueue. A remote Bot is refused.
+3. **A live run advances only when its ephemeral Bot replies, following the graph's edges in order.** That reply is the chat line. Nodes start only when their forward predecessors finish and edges reach them. There is no scripted or seeded run path: `workflow/state` exposes only `live === true` runs. A run does not create a schedule. `scheduleLabel` is display text. When the host can create Bots, starting a live run (`assign`, `run_workflow`, `ingest`) spawns one ephemeral Bot per node from that node's prompt, role, model and tools, sends it the step from the Main Bot, and removes every instance when the run finishes, fails for good, or is reset. A `failOnce` retry keeps them. They are hidden and left out of the sidebar. Loading the plugin does not spawn Bots for the default workflows. Loading is also the one moment a run the host left behind is noticed: a run still marked `running` is abandoned, so loading releases its instances and records the run as `failed`. Nothing resumes it. A run that already ended keeps its own status (#1388). A dispatch that does not land is not marked handed. The chat names the code, and the next hand-off tries that node again. It is not sent twice in the same hand-off. A reply that says `could not answer your message` or `model call failed` fails that node and does not start its successor. A 429 or rate-limit mention in any other reply does not.
+4. Each workflow keeps a FIFO queue and up to `maxConcurrent` live runs (default 2, an integer from 1 to 8 on the record or via `workflow/concurrency`). The host runs at most 6 live runs at once. A task that does not fit is enqueued. When a run finishes, every workflow with a free slot is drained, oldest enqueue first, until the host cap. A new assign on a workflow that already has a queue waits behind it. A task does not replace a running run or release that run's Bots. Migrating an old store keeps only runs that were still `running` with ephemeral Bot ids; other legacy scripted rows are dropped from active state (finished tasks may remain in lane history). History records a finished or failed live run. Lowering the cap does not stop a run that has already started. Assigning `{ botId }` claims the card for that local Bot and does not enqueue. A remote Bot is refused.
 5. A node declares up to eight inputs and eight outputs. A required input is an output of the same name on an ancestor, or `task`, `title`, or `brief` on a root. A start with no provider is refused, and Bots spawned for that attempt are released. On a Bot-backed run a successor stays queued until its required inputs are present. If every forward predecessor is done, failed or skipped and an input is still missing, that node fails and the run stops. The dispatch text carries `Input <name>: <value>`. The Bot reports `OUTPUT <name>: <value>`; a single declared output may be the reply body. Nodes start in edge order.
 6. Each node is a real ephemeral Bot for that run, then it is removed. A permanent sidebar Bot (`botId`) is optional and is not required for the step to run. `tools` on the node is what that Bot may use: `github` grants `mcp__github__*` (pull requests, reviews, comments); `bash` or `shell` sets the permission to `danger-full-access` and allows a full-access shell; any other step gets `workspace-write`. A hidden run Bot cannot show an approval card, so a granted tool is allowed and a connector it did not name is refused. The host stores this on the run Bot as `stepTools` and `permission`.
 7. A loop edge (`loop: true`, `max` from 1 to 8, default 3, optional `until: { output, eq }`) is the only cycle. The body runs again until `until` matches or `max` runs have finished, and the forward edges wait until then. Restarting the body drops the branch choice made inside it and queues a sibling that the previous pass skipped, so the next pass can take the other side. A `when: { output, eq }` edge is taken only when that output equals `eq`. `when: { else: true }` is taken only when no other `when` matched. A node whose forward edges are all closed is `skipped` and does not block a join. A run cannot spin: every loop has a max. Settings → Workflow graphs can add a link, a condition or a loop.

 ## Tests
 
-`plugins/workflow/test/`: graph advance and join, graph edit, assign and persistence, the FIFO queue and concurrency cap, Bot-reply advance, a dispatch that fails without being marked handed, disposing releases the Bots before the record drops their ids and a released runner name is reusable again, assign-to-bot versus assign-to-workflow, inputs and outputs along edges, a loop that breaks and an if/else branch, templates, `define` / `runNamed`, the matcher, ephemeral spawn and cleanup, the reply middleware, the client canvas, the settings page (including a condition and a loop), rename and delete (factory refuse, cleanup on delete, #1434), and a sidebar click that leaves the Workflows section in place. Run `npm test` in `plugins/workflow`. The host seam that applies `ownerBotId` is `core/test/task-route.test.js`. The host omission of run Bots, and the grant of `stepTools` plus the hidden-approval answer, is `core/test/flybot.test.js`. Which connectors a run Bot may call is `core/test/connector-access.test.js`.
