-name: MCP Stdio Transport Regression
-
-# Regression test for molecule-ai-workspace-runtime#61:
-# asyncio.connect_read_pipe / connect_write_pipe fail with
-# ValueError: "Pipe transport is only for pipes, sockets and character devices"
-# when stdout is a regular file (openclaw capture, CI tee, debugging).
-#
-# This workflow reproduces the exact failure mode and verifies the
-# fallback to direct buffer I/O works. It runs on every PR that
-# touches the MCP server or this workflow, plus nightly cron.
-#
-# Why a separate workflow (not folded into ci.yml python-lint):
-#   - The test needs to spawn the MCP server with stdout redirected
-#     to a regular file (not a TTY/pipe), which conflicts with
-#     pytest's own capture mechanism.
-#   - It exercises the actual process spawn path (python a2a_mcp_server.py)
-#     not just unit-test mocks — closer to the real openclaw integration.
-#   - A dedicated workflow surfaces stdio-specific regressions without
-#     coupling to the broader Python test suite's coverage gate.

+/**
+ * Tests for ExternalConnectModal — the modal surfaced after creating a
+ * runtime="external" workspace. Surfaces workspace_auth_token + ready-to-paste
+ * snippets so the operator can configure their off-host agent.
+ *
+ * Coverage:
+ *   - Renders nothing when info=null
+ *   - Opens dialog when info is provided
+ *   - Default tab: "Universal MCP" when universal_mcp_snippet present, else "Python SDK"
+ *   - Tab switching between all available tabs
+ *   - Snippets show with auth_token replacing placeholders
+ *   - Copy button: calls clipboard API, shows "Copied!", clears after 1.5s
+ *   - Copy failure: shows fallback textarea
+ *   - "I've saved it — close" calls onClose
+ *   - Security warning: one-time token display
+ *   - Fields tab shows raw values
+ *   - Tabs hidden when their snippet is absent
+ *
+ * Fake timers: applied per-describe to avoid mixing with waitFor. Tests that
+ * use waitFor (which needs real timers) run without fake timers. Tests that
+ * verify setTimeout behavior use vi.useFakeTimers() + act(vi.advanceTimersByTime).

 /**
- * Tests for AttachmentLightbox — shared fullscreen modal for image/PDF
- * fullscreen viewing.
+ * AttachmentLightbox — fullscreen modal for image / PDF preview.
  *
- * Covers: open/close rendering, backdrop click-to-close, Esc key close,
- * role/dialog + aria attributes, close button, prefers-reduced-motion.
+ * Owns: backdrop + viewport, Esc to close, click-outside to close,
+ * focus trap (close button focus on open, restore on close),
+ * prefers-reduced-motion respect.
+ *
+ * Coverage:
+ *   - Null when open=false
+ *   - Renders dialog with correct ARIA roles and label when open
+ *   - Close button present and wired
+ *   - Focus moves to close button on open
+ *   - Focus restores to previous element on close
+ *   - Esc key closes via document listener
+ *   - Click outside closes
+ *   - Click on content does NOT close (stopPropagation)
+ *   - Cleanup removes document listener on unmount
+ *
+ * NOTE: No @testing-library/jest-dom — use DOM APIs.

- * 16 cases covering:
- * - PendingAttachmentPill: name, size, aria-label, onRemove, one-button guard
- * - AttachmentChip: name+glyph, size, no-size, title, onDownload, tone=user/agent, one-button guard
+ * Covers:
+ *   - PendingAttachmentPill renders file name, formatted size, × button
+ *   - PendingAttachmentPill × button has correct aria-label
+ *   - PendingAttachmentPill calls onRemove when × clicked
+ *   - PendingAttachmentPill renders exactly one button
+ *   - AttachmentChip renders attachment name and download glyph
+ *   - AttachmentChip renders size when provided
+ *   - AttachmentChip omits size span when size is undefined
+ *   - AttachmentChip calls onDownload(attachment) on click
+ *   - AttachmentChip title attribute for hover tooltip
+ *   - AttachmentChip tone=user applies blue accent classes
+ *   - AttachmentChip tone=agent applies surface classes
+ *   - AttachmentChip renders exactly one button
  *
- * Pattern: render the real component, inspect actual DOM output.
- * No mocking of the components themselves.
+ * NOTE: No @testing-library/jest-dom import — use textContent / className /

-# Production Auto-Deploy
-
-`molecule-core` deploys production tenant code automatically from Gitea Actions.
-
-This runbook is an implementation-specific companion to `runbooks/sop-production-cicd.md`.
-
-## Default Flow
-
-On a push to `main` that touches deployable code, `.gitea/workflows/publish-workspace-server-image.yml`:
-
-1. Builds and pushes platform and tenant ECR images tagged `staging-<sha>` and `staging-latest`.
-2. Self-tests the production deploy helper and workflow-YAML linter.
-3. Waits for strict required push contexts on the same commit to become `success`.
-4. Calls production control-plane `POST /cp/admin/tenants/redeploy-fleet` with `target_tag=staging-<sha>`.
-5. Verifies every redeploy result is healthy and every tenant returns the same Git SHA from `/buildinfo`.
-
-The deploy workflow intentionally does not use Gitea `concurrency` because Gitea 1.22.6 can cancel queued runs even when `cancel-in-progress: false`.
-
-## Kill Switch
-
-Set either repository variable or secret:
-
-```text
-PROD_AUTO_DEPLOY_DISABLED=true
-```
-
-The image publish still runs, but the production redeploy step exits successfully without touching tenants.
-Immediately before the production POST, the workflow re-checks the live Gitea repo variable when `PROD_AUTO_DEPLOY_CONTROL_TOKEN` can read Actions variables. If that token is not configured, the job-start value is still honored.
-
-## Tunables
-
-Repository variables:
-
-```text
-PROD_CP_URL=https://api.moleculesai.app
-PROD_AUTO_DEPLOY_CANARY_SLUG=hongming
-PROD_AUTO_DEPLOY_SOAK_SECONDS=60
-PROD_AUTO_DEPLOY_BATCH_SIZE=3
-PROD_AUTO_DEPLOY_DRY_RUN=false
-PROD_MANUAL_REDEPLOY_TARGET_TAG=staging-<known-good-sha>
-```
-
-Secrets required:
-
-```text
-CP_ADMIN_API_TOKEN
-AUTO_SYNC_TOKEN
-PROD_AUTO_DEPLOY_CONTROL_TOKEN
-AWS_ACCESS_KEY_ID
-AWS_SECRET_ACCESS_KEY
-```
-
-`AUTO_SYNC_TOKEN` is only used to read Gitea commit statuses while waiting for required push contexts.
-`PROD_AUTO_DEPLOY_CONTROL_TOKEN` is optional but recommended so the pre-POST kill-switch check can read the live `PROD_AUTO_DEPLOY_DISABLED` Actions variable.
-
-## Manual Fallback
-
-Use `.gitea/workflows/redeploy-tenants-on-main.yml` when the automatic path needs to be rerun or rolled back. Gitea 1.22.6 does not support reliable `workflow_dispatch` inputs, so rollback uses a repo variable:
-
-1. Set `PROD_MANUAL_REDEPLOY_TARGET_TAG=staging-<known-good-sha>`.
-2. Dispatch `manual-redeploy-tenants-on-main`.
-3. Clear `PROD_MANUAL_REDEPLOY_TARGET_TAG` after the rollback finishes.
-
-With no variable set, the fallback redeploys `staging-<current-main-sha>`.

-# SOP: Production CI/CD Changes
-
-Production CI/CD changes are higher risk than ordinary CI edits. They can publish images, deploy tenants, promote tags, mutate branch protection, or change merge behavior. This SOP separates rules that must be enforced by code from rules that require human judgment.
-
-## Programmatic Gates
-
-The workflow YAML linter is the first line of enforcement:
-
-```bash
-python3 .gitea/scripts/lint-workflow-yaml.py --workflow-dir .gitea/workflows
-```
-
-It must reject:
-
-- Gitea-hostile syntax such as `workflow_dispatch.inputs`, `workflow_run`, workflow name collisions, slash-containing workflow names, and unsupported cross-repo action references.
-- Production deploy workflows that rely on `concurrency.cancel-in-progress: false` for serialization.
-- Production deploy workflows that print raw control-plane responses or raw `.error` fields into CI logs.
-- Production redeploy workflows with no kill switch or rollback/pin control.
-
-Production deploy helpers must also unit-test:
-
-- Disable-flag parsing.
-- Required status context selection.
-- Terminal status handling for `failure`, `error`, `cancelled`, `canceled`, and `skipped`.
-- Production control-plane URL guards.
-- Rollback target/pin handling when applicable.
-
-## Required PR Evidence
-
-Every production CI/CD PR must include concrete answers for:
-
-- Root cause: what production failure mode or process gap is being closed.
-- Deploy gate: which exact contexts must be green before production side effects.
-- Kill switch: how to stop deployment without reverting the PR.
-- Verification: how production state is proven after deployment.
-- Logging: proof that CI logs do not contain raw production runtime, SSM, or secret-adjacent output.
-- Rollback: the exact command, variable, or workflow to return to a known-good tag/digest.
-
-## Human Review
-
-Production CI/CD PRs need non-author review across these roles:
-
-- DevOps: Gitea Actions semantics, branch protection, merge queue, and runner behavior.
-- SRE: rollout order, tenant health checks, observability, and partial-deploy recovery.
-- Security: secrets, token scopes, log redaction, and production endpoint targeting.
-
-Critical or Required review findings must be closed with one of:
-
-- A code change plus verification.
-- An evidence-backed rejection.
-- A follow-up issue only if the finding is explicitly not merge-blocking.
-
-Acknowledgement alone is not closure.
-
-## Production Defaults
-
-Production deploys should fail closed:
-
-- Missing tenant result: fail.
-- Tenant unhealthy: fail.
-- `/buildinfo` unreachable: fail.
-- SHA mismatch: fail.
-- Required status cancelled/skipped/missing past timeout: fail.
-
-Staging may tolerate warnings during rollout development; production should not.
-
-## Gitea 1.22.6 Constraints
-
-Do not design production CI/CD around unsupported or unreliable features:
-
-- No `workflow_run`.
-- No reliable `workflow_dispatch.inputs`.
-- Do not assume `concurrency.cancel-in-progress: false` serializes queued runs.
-- Do not rely on a masked aggregate status as the only production deploy gate.
-
-If these constraints change after a Gitea upgrade, update this SOP and the workflow linter in the same PR.

-//
-// These test the fix for issue #159: when proxyA2ARequest returns an error but we have a
-// non-empty response body with a 2xx status code, executeDelegation must treat it as success.
-// The error is a delivery/transport error (e.g., connection reset after response was received).
-// Previously, executeDelegation marked these as "failed" even though the work was done,
-// causing retry storms and "error" rendering in canvas despite the response being available.
-//
-// Test strategy: spin up a mock A2A agent server, set up the source/target DB rows, call
-// executeDelegation directly, and verify the activity_logs status and delegation status.

-//     proxyA2ARequest: body read gets io.EOF (partial body read), returns (200, <partial>, BadGateway).
-//     isTransientProxyError(BadGateway) = TRUE → retry.
-//   - Attempt 2: server does the same thing (closes after partial body).
-//     proxyA2ARequest: same (200, <partial>, BadGateway).
-//     isTransientProxyError(BadGateway) = TRUE → retry AGAIN (but outer context will fire soon,
-//     or we get one more attempt). For the test we let it run.
-//     POST-FIX: the executeDelegation new condition sees status=200, body=<partial>, err!=nil
-//     and routes to handleSuccess immediately.
-//
-// The key pre/post-fix difference: pre-fix, executeDelegation received status=0 (hardcoded)
-// even when the server sent 200, so the condition always failed. Post-fix, status=200 is
-// preserved through the error return path (proxyA2ARequest now returns resp.StatusCode, respBody).
