+# Regression test for molecule-ai-workspace-runtime#61:

+# 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 buildDeployMap — the pure tree-computation core inside
+ * useOrgDeployState.
+ *
+ * Issue: #742 (buildDeployMap unit tests, #2071 follow-up).
+ *
+ * The function takes a flat list of NodeProjections and a set of
+ * deletingIds, then computes per-node OrgDeployState:
+ *   isActivelyProvisioning — node itself is provisioning
+ *   isDeployingRoot       — node is a root AND has provisioning descendants
+ *   isLockedChild         — node is a deleting child OR a non-root in a deploying tree
+ *   descendantProvisioningCount — total provisioning descendants (roots only)
+ *
+ * Coverage:
+ *   §1  Empty input
+ *   §2  Single node — no parent, non-provisioning
+ *   §3  Single node — no parent, provisioning
+ *   §4  Single node — has parent (parent exists)
+ *   §5  Parent not in projections → node treated as root
+ *   §6  Two nodes: root (non-provisioning) + child
+ *   §7  Two nodes: root (provisioning) + child
+ *   §8  Three-level tree: grandparent (provisioning) → parent → child
+ *   §9  DeletingIds contains a non-root node → isLockedChild=true
+ *   §10 DeletingIds contains the root → root isLockedChild=true
+ *   §11 Two independent roots, one provisioning
+ *   §12 Provisioning count: root has 2 provisioning descendants
+ *   §13 Non-root node with provisioning status → isActivelyProvisioning=true
+ *   §14 findRoot memoization: repeated calls don't re-walk the chain
+ *   §15 deletingIds + provisioning interact: deleting takes isLockedChild
+ *   §16 Child of provisioning root (not itself provisioning) → isLockedChild=true
+ *   §17 Deep chain (5 levels), no provisioning → all nodes unlocked
+ *   §18 Deep chain (5 levels), middle node is provisioning root
+ *   §19 Node with parentId pointing to non-existent node → treated as root

+# 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.
