- *   - Edit memory entry (inline)
- *   - Edit 409 conflict shows retry hint
- *   - Advanced toggle shows/hides KV section
- *   - Awareness dashboard expand/collapse
- *   - Awareness URL includes workspaceId
- *   - Refresh button reloads memory
- *   - Error clears when appropriate actions are taken

 ## Overview
 
-The workspace runtime uses a **pluggable adapter architecture** — each agent infrastructure (Claude Code, OpenClaw, LangGraph, CrewAI, AutoGen, etc.) has its own adapter that bridges the A2A protocol to the infra's native interface.
+The workspace runtime uses a **pluggable adapter architecture** — each maintained agent infrastructure (Claude Code, Codex, Hermes, OpenClaw) has its own adapter that bridges the A2A protocol to the infra's native interface.
 
 Adapters live in `workspace/adapters/<runtime>/` and are auto-discovered at startup. Each adapter implements `BaseAdapter` (from `adapters/base.py`) with `setup()` and `create_executor()` methods.
 
 The runtime is selected via `config.yaml`:
 
 ```yaml
-runtime: claude-code    # or: langgraph, openclaw, deepagents, crewai, autogen
+runtime: claude-code    # or: codex, hermes, openclaw
 runtime_config:
   model: sonnet
   auth_token_file: .auth-token

At startup, `main.py` checks the `runtime` field in `config.yaml`, discovers the matching adapter in `adapters/<runtime>/`, calls `adapter.setup(config)` then `adapter.create_executor(config)` to get an `AgentExecutor` that handles A2A requests.

-CLI runtimes keep the same memory tool surface as the Python runtime. When `AWARENESS_URL` and `AWARENESS_NAMESPACE` are injected into the workspace, `commit_memory` and `search_memory` route to the workspace's own awareness namespace instead of the fallback platform memory API. This keeps the agent contract stable while giving each workspace an isolated memory scope.
+CLI runtimes keep the same memory tool surface as the Python runtime: `commit_memory` / `commit_memory_v2` / `search_memory` / `commit_summary` / `forget_memory` are exposed via the workspace's MCP bridge and route through the platform's v2 memory plugin under the workspace's `workspace:<id>` namespace.

+# Runbook: stale CI umbrella with green sub-jobs — compensating status
+
+**When to use this:** A PR's `CI / all-required (pull_request)` status is `failure` (so branch protection blocks the merge), but all 5 required sub-jobs (`Detect changes`, `Platform (Go)`, `Canvas (Next.js)`, `Shellcheck (E2E scripts)`, `Python Lint & Test`) actually succeeded. The umbrella job's internal 40-min poll deadline elapsed before the success statuses propagated through Gitea's commit-status pipeline.
+
+**When NOT to use this:** Any required sub-job actually failed. The umbrella correctly reflects reality; a compensating-status post would lie.
+
+This pattern parallels what `.gitea/workflows/status-reaper.yml` does for default-branch `(push)` status drift, but applied to PR umbrellas instead of main-branch contexts.
+
+## Diagnose
+
+1. Look up the umbrella status:
+
+   ```bash
+   TOK=$(cat ~/.molecule-ai/gitea-token)
+   API=https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core
+   PR=<pr-number>
+   sha=$(curl -sS -H "Authorization: token $TOK" "$API/pulls/$PR" | python3 -c "import sys,json; print(json.load(sys.stdin)['head']['sha'])")
+   curl -sS -H "Authorization: token $TOK" "$API/commits/$sha/status" \
+     | python3 -c "import sys,json; [print(s['status'], s['context']) for s in json.load(sys.stdin)['statuses'] if 'all-required' in s['context']]"
+   ```
+
+2. Look up the actual sub-job statuses in the Gitea DB:
+
+   ```bash
+   ssh root@5.78.80.188 "docker exec molecule-postgres-1 psql -U gitea -d gitea -tAc \"
+     SELECT aj.name,
+       CASE aj.status WHEN 1 THEN 'success' WHEN 2 THEN 'failure' WHEN 3 THEN 'cancelled' WHEN 4 THEN 'skipped' WHEN 5 THEN 'waiting' WHEN 6 THEN 'running' END
+     FROM action_run ar JOIN action_run_job aj ON aj.run_id=ar.id
+     WHERE ar.repo_id=17 AND ar.workflow_id='ci.yml' AND ar.commit_sha='$sha'
+     ORDER BY aj.id;\""
+   ```
+
+   The 5 required-by-umbrella sub-jobs must all be `success`. (`Canvas Deploy Reminder` is intentionally not required — its state doesn't matter.)
+
+## Recover
+

+
+The status posts immediately; the merge gate flips green within ~5 seconds.
+
+**Always include WHO and WHY in the `description` field** so the audit trail is honest. Future operators (and `audit-force-merge.yml` consumers) need to be able to tell a recovery from a real bypass.
+
+## Why this happens
+
+- The umbrella's 40-min internal poll loop (`.gitea/workflows/ci.yml` → `all-required` job → `Wait for required CI contexts` step) treats `missing` statuses as pending.
+- Status propagation: a job completing on a runner posts its `action_run_job.status=1` row first, then Gitea's notifier walks `action_run_job` → `commit_status` table. Under high write load (many concurrent PRs synchronizing) the notifier walk can lag by several minutes.
+- If propagation lag pushes the last sub-job's commit-status past the umbrella's 40-min wall-clock deadline, the umbrella fails even though the sub-jobs were green well within the window.
+- The umbrella correctly does not retry once it has emitted a terminal status (per RFC internal#219 design — retries would mask real failures).
+
+## Prevent
+
+Most cases are downstream of the runner-pool dispatch deadlock fixed by commit `7da843f2` (issue #1779). With the umbrella running on the dedicated `ci-meta` pool, sub-jobs are no longer competing for runners with their own umbrella, so propagation completes well before the 40-min deadline in normal load.
+
+If you find yourself reaching for this runbook frequently, that's the signal to either:
+- Raise `timeout-minutes` on the umbrella above 45.
+- Build the `umbrella-reaper.yml` auto-recovery described in issue #1780 (this runbook is its precursor).
+
+## Cross-refs
+
+- Issue #1780 — original write-up; tracks auto-recovery
+- Issue #1779 — runner-pool deadlock; root cause of the propagation lag in most cases
+- `.gitea/workflows/status-reaper.yml` — sibling pattern for default-branch `(push)` status drift
+- `.gitea/workflows/audit-force-merge.yml` — audits bypass merges; this runbook's `description` field is what makes a compensating-status merge auditable vs. opaque
+
+## Session-local examples
+
+The pattern was used twice during the 2026-05-24 CTO-bypass session:
+
+- **PR #1737** merged via compensating-status — all 5 sub-jobs green, umbrella timed out on propagation race. Merge commit `d5941906`.
+- **PR #1759** merged via compensating-status — 4/5 sub-jobs green, the 5th (`Platform (Go)`) was an inherited-from-main failure (templates_test fixtures bug, tracked as #1778, fixed in #1781). The compensating-status description called out the inherited failure honestly. Merge commit `220a04b1`.
