In `@api-docs.yml`:
- Around line 1358-1369: Add a WorkflowDelay schema definition based on
db.WorkflowDelay, including its status values and fields, then add a delay
property referencing WorkflowDelay to WorkflowNodeRunStatus alongside node,
task, and approval.
In `@db/sql/migrations/v2.20.2.sql`:
- Around line 3-19: Add a composite unique constraint to the
project__workflow_delay table for workflow_run_id and workflow_node_id, ensuring
each workflow run and node pair has at most one delay while preserving the
existing indexes and foreign keys.
In `@db/Workflow.go`:
- Line 23: Update the backup tag on the DelaySeconds field in the Workflow node
definition to use delay_seconds instead of the misspelled delay_secodns value,
preserving the existing field type and behavior.
Apply the same fix in `@db/Workflow.go` around lines 63 - 64: Same misspelled
backup tag and remediation in the related field declaration.
In `@pro/db/sql/workflow.go`:
- Around line 90-112: Implement the delay persistence methods on
WorkflowStoreImpl—GetWorkflowDelays, GetWorkflowDelay, CreateWorkflowDelay,
UpdateWorkflowDelay, ResolveWorkflowDelayIfWaiting, and
GetExpiredWorkflowDelays—with the required database queries and writes,
preserving their declared return contracts. Do not leave zero-value success
stubs; if delay nodes are intentionally unsupported, return a non-nil
unsupported error from each relevant method and reject them before execution.
In `@web/src/views/project/WorkflowEditor.vue`:
- Around line 268-283: Update the delay editor field bound to
editingNode.delay_seconds to include a step of 1 and ensure the existing
validation rejects fractional or non-positive values before applyNodeEdit saves
the node. Keep valid positive integer delays accepted and apply the same
validation to all delay input paths.
- Line 218: Reformat the v-if condition in WorkflowEditor so it stays within the
100-column limit, either by splitting the condition across lines or moving it
into a computed property. Preserve the existing checks for editingNode.kind and
editingNodeTemplate, then run the web lint command to verify formatting.

Add delay state to WorkflowNodeRunStatus.
WorkflowRun.vue reads n.delay.status, but the schema defines only node, task, and approval. Add a WorkflowDelay definition and reference it through a delay property. Include the status values and fields from db.WorkflowDelay.

Use backup:"delay_seconds" for DelaySeconds.
The current tag serializes this field as delay_secodns, which does not match the database and JSON field name. Correct the backup tag wherever this field is declared so backups use the expected key.

Implement the delay store methods or return an explicit unsupported error.
These methods return zero values and nil errors without database operations. CreateWorkflowDelay therefore reports success without persistence. Reads return no delay. Resolution always reports false. A workflow using this store cannot resume delay nodes correctly.
Implement the required queries and writes. If this deployment must not support delay nodes, return a non-nil unsupported error and reject delay nodes before execution.

Reject fractional delay values before save.
The API contract defines delay_seconds as an integer with a minimum of 1. db/Workflow.go stores it as *int. A value such as 1.5 can pass the current problems check and then fail when the API decodes the payload. (github.com)
Add step="1" and validate that the value is a positive integer.
Proposed validation fix
type="number"
min="1"
+ step="1"
:label="$t('workflowDelaySeconds')"
...
- const badDelay = nodes.some(
- (n) => n.kind === 'delay' && (n.delay_seconds == null || n.delay_seconds <= 0),
- );
+ const badDelay = nodes.some((n) => {
+ if (n.kind !== 'delay') return false;
+ const seconds = Number(n.delay_seconds);
+ return !Number.isInteger(seconds) || seconds <= 0;
+ });Also applies to: 407-411

The workflow run view showed a static "Delay 60s" label for a delay node regardless of how much of the wait was left, giving no sense of progress while a run is blocked on it. - WorkflowRun.vue exposes node.id -> resume_at for nodes currently waiting on a delay (from the run's per-node delay status added server-side). - WorkflowGraph.vue renders that as a live "Ns left" / "Nm Ss left" title on the node, ticking every second while the run view is open. - The per-second tick patches only the node title's text content (refreshCountdowns) instead of going through the existing refreshStatuses repaint, which recreates the node's DOM and would otherwise restart its running/waiting pulse animation every second. - Static "Delay Ns" label is kept for the editor and for any node without a live waiting delay.
