+# Fires after any of the staging-branch quality gates complete. When ALL

+# to that SHA automatically — closing the gap that historically let
+# features sit on staging for weeks waiting for a bulk promotion PR
+# (see molecule-core#1496 for the 1172-commit example).
+#
+# Safety model:
+# - Runs ONLY on workflow_run events for the staging branch.
+# - Requires EVERY named gate workflow to have the same head_sha and
+#   all be `conclusion == success`. If any of them is red, skipped,
+#   cancelled, or pending, we abort (stay on the current main).
+# - Uses --ff-only: refuses to advance main if main has diverged from
+#   the staging history (e.g. a hotfix landed directly on main). In
+#   that case a human resolves the fork.
+# - Writes a commit summary so the promote shows up in git log as a
+#   deliberate act, not a stealth move.

+# the 8 workspace-template-* repos depend on.
+#
+# Triggered by:
+#   - Pushing a tag matching `runtime-vX.Y.Z` (the version is derived from
+#     the tag — `runtime-v0.1.6` publishes `0.1.6`).
+#   - Manual workflow_dispatch with an explicit `version` input (useful for
+#     dev/test releases without tagging the repo).
+#   - Auto: any push to `staging` that touches `workspace/**`. The version
+#     is derived by querying PyPI for the current latest and bumping the
+#     patch component. This closes the human-in-loop gap that caused the
+#     2026-04-27 RuntimeCapabilities ImportError outage — adapter symbol
+#     additions in workspace/adapters/base.py used to require an operator
+#     to remember to publish; now the merge itself triggers the publish.
+#
+# The workflow:
+#   1. Runs scripts/build_runtime_package.py to copy workspace/ →
+#      build/molecule_runtime/ with imports rewritten (`a2a_client` →
+#      `molecule_runtime.a2a_client`).
+#   2. Builds wheel + sdist with `python -m build`.
+#   3. Publishes to PyPI via the PyPA Trusted Publisher action (OIDC).
+#      No static API token is stored — PyPI verifies the workflow's
+#      OIDC claim against the trusted-publisher config registered for
+#      molecule-ai-workspace-runtime (Molecule-AI/molecule-core,
+#      publish-runtime.yml, environment pypi-publish).
+#
+# After publish: the 8 template repos pick up the new version on their
+# next image rebuild (their requirements.txt pin
+# `molecule-ai-workspace-runtime>=0.1.0`, so any new release is eligible).
+# To force-pull immediately, bump the pin in each template repo's
+# requirements.txt and merge — that triggers their own publish-image.yml.

+# to main, but running tenants pulled their image once at boot and
+# never re-pull. Users see stale code indefinitely.

+# This workflow closes the gap by calling the control-plane admin

+#   3. Calls redeploy-fleet with canary_slug=hongmingwang and a 60s

+name: Sweep stale Cloudflare DNS records
+
+# Janitor for Cloudflare DNS records whose backing tenant/workspace no
+# longer exists. Without this loop, every short-lived E2E or canary
+# leaves a CF record on the moleculesai.app zone — the zone has a
+# 200-record quota (controlplane#239 hit it 2026-04-23+) and provisions
+# start failing with code 81045 once exhausted.
+#
+# Why a separate workflow vs sweep-stale-e2e-orgs.yml:
+#   - That workflow operates at the CP layer (DELETE /cp/admin/tenants/:slug
+#     drives the cascade). It assumes CP has the org row to drive the
+#     deprovision from. It doesn't catch records left behind when CP
+#     itself never knew about the tenant (canary scratch, manual ops
+#     experiments) or when the cascade's CF-delete branch failed.
+#   - sweep-cf-orphans.sh enumerates the CF zone directly and matches
+#     each record against live CP slugs + AWS EC2 names. It catches
+#     leaks the CP-driven sweep can't.
+#
+# Safety: the script's own MAX_DELETE_PCT gate refuses to nuke more
+# than 50% of records in a single run. If something has gone weird
+# (CP admin endpoint returns no orgs → every tenant looks orphan) the
+# gate halts before damage. Decision-function unit tests in

+#### Auto-merge & the "extra commit" trap
+
+**Two system guards protect against pushing commits after auto-merge has been enabled.** Don't try to work around them — they exist because we shipped a half-merged PR on 2026-04-27 (`#2174` merged with only its first commit; the second was orphaned on a branch GitHub had already deleted).
+
+1. **Repo-wide:** "Automatically delete head branches" is on. Once a PR merges, the branch is deleted server-side. Any subsequent `git push` to that branch fails with `remote rejected — no such branch`.
+
+2. **CI:** the `pr-guards` workflow (calling [molecule-ci `disable-auto-merge-on-push`](https://github.com/Molecule-AI/molecule-ci/blob/main/.github/workflows/disable-auto-merge-on-push.yml)) fires on every push to an open PR. If auto-merge was already enabled, it's disabled and a comment is posted. You must explicitly re-enable after verifying the new commit.
+
+**Workflow rules that follow from the guards:**
+- Push **all** commits before running `gh pr merge --auto`.
+- If you realize you need another commit after enabling auto-merge: push it, then **re-run** `gh pr merge --auto` — the guard will already have disabled it. The disable + re-enable is the verification step.
+- For changes that depend on each other across PRs (e.g. a build-script change + a workflow that consumes it), prefer a **stack** of PRs (PR-B branched off PR-A's branch, opened only after PR-A is in queue) over amending one in-flight PR.

+# Coverage Floor
+
+CI enforces three coverage gates on `workspace-server` (Go). All defined in
+`.github/workflows/ci.yml` → `platform-build` job.
+
+## Current floors (2026-04-23)
+
+| Gate | Threshold | What fails |
+|---|---|---|
+| **Total floor** | `25%` | `go tool cover -func` reports total below floor |
+| **Critical-path per-file floor** | `10%` | Any non-test source file in a security-critical path with coverage ≤10% |
+| **Per-file report** | advisory | Printed in CI log, sorted worst-first, does not fail |
+
+Total floor starts at 25% (unchanged from pre-#1823 to keep this PR strictly
+additive). The new protection is the critical-path per-file floor, which
+directly closes the gap that prompted the issue. Ratchet plan below begins
+the month after to let the team first observe the gate in action.
+
+## Security-critical paths (Gate 2)
+
+Changes to these paths have historically introduced security issues (CWE-22,
+CWE-78, KI-005, SSRF) or billing/auth risk. Coverage must not drop to zero.
+
+- `internal/handlers/tokens*`
+- `internal/handlers/workspace_provision*`
+- `internal/handlers/a2a_proxy*`
+- `internal/handlers/registry*`
+- `internal/handlers/secrets*`
+- `internal/middleware/wsauth*`
+- `internal/crypto*`
+
+## Ratchet plan
+
+Floor ratchets upward on a fixed cadence. Any ratchet is a PR — reviewable,
+reversible, and creates history. The table below is the intended schedule.
+
+| Date | Total floor | Critical-path floor | Notes |
+|---|---|---|---|
+| 2026-04-23 | 25% | 10% | Initial gate (this file). |
+| 2026-05-23 | 30% | 20% | First ratchet |
+| 2026-06-23 | 40% | 30% | |
+| 2026-07-23 | 50% | 40% | |
+| 2026-08-23 | 55% | 50% | |
+| 2026-09-23 | 60% | 60% | |
+| 2026-10-23 | 70% | 70% | Target steady-state |
+
+The target end-state matches the per-role QA prompts which specify
+"coverage >80% on changed files". CI enforces the floor; reviewers still
+enforce the per-PR bar.
+
+## Exceptions
+
+If a critical-path file genuinely cannot have coverage above the floor (e.g.
+thin wrapper around a third-party SDK with no branches to test), add an entry
+here with:
+
+1. **File**: `internal/handlers/example.go`
+2. **Reason**: Why coverage can't hit the floor
+3. **Tracking issue**: GitHub issue for the real fix
+4. **Expiry**: 14 days from entry date; after expiry either coverage is fixed
+   or the issue is closed as "accepted technical debt"
+
+### Active exceptions
+
+*(none — add here if you need to land code that legitimately can't clear the floor)*
+
+## Why this gate exists
+
+Issue #1823: an external audit found critical files at 0% coverage despite
+test files existing with hundreds of lines. The existing CI step measured
+coverage but didn't enforce a meaningful threshold. Any file could go from
+80% → 0% and CI stayed green, because the single gate (total ≥25%) ignored
+per-file distribution.
+
+This gate makes "no untested critical paths merged" a mechanical property of
+the CI, not a behavioural property of QA agents or individual reviewers —
+which is the only way to make it survive fleet outages, agent rotations, or
+QA process changes.

+# Give Your AI Agent Browser Superpowers: Chrome DevTools MCP Integration
+
+Every AI agent platform eventually gets asked the same question: "Can it interact with a web interface?" The answer is usually some variant of "sort of — give it your credentials and hope for the best." That's not a real answer. It's a trust fall.
+
+Chrome DevTools MCP changes this. It gives your AI agent a structured, governed interface to a real Chrome browser session — with full **MCP browser automation** capability and an audit trail that actually answers the question: "which agent touched what, and what did it do?"
+
+This post covers what Chrome DevTools MCP is, how Molecule AI's governance layer makes it enterprise-safe, and how to put it to work in your agent fleet.
+
+---
+
+## What is Chrome DevTools MCP?
+
+Chrome DevTools MCP is an integration between the [MCP (Model Context Protocol)](https://modelcontextprotocol.io) and Google Chrome's DevTools Protocol. MCP is a standardized interface layer that lets AI agents connect to external tools with consistent tooling, authentication, and telemetry. The DevTools Protocol is Chrome's native debugging interface — the same interface your browser's developer tools use to inspect pages, capture network traffic, and control the browser.
+
+When you connect an AI agent to Chrome DevTools via MCP, you get:
+
+- **Full CDP access** — navigate, click, type, screenshot, evaluate JavaScript, read network logs, intercept requests, read cookies and local storage
+- **MCP protocol layer** — structured JSON-RPC instead of raw CDP, consistent tool naming, type-safe parameters
+- **Molecule AI governance layer** — org API key attribution, audit logging, session scoping, instant revocation
+
+The third item is what separates this from "use Puppeteer with an API key." It's the difference between browser automation AI agents and browser automation AI agents with a compliance story.
+
+---
+
+## The Browser Problem: Trust Falls and Black Boxes
+
+When most teams give an AI agent browser access, the workflow looks like this:
+
+1. Agent receives a task ("find our competitors' pricing pages")
+2. Agent uses browser credentials to log into Chrome
+3. Agent navigates, reads, screenshots, and reports
+4. Nobody knows exactly what the agent did, which session it used, or whether credentials were exposed
+
+This is a trust fall, not a governance model. The agent *can* do the task. But you have no audit trail if something goes wrong. No way to revoke access if the agent's behavior becomes unexpected. No attribution if you need to trace a call back to a specific integration.
+
+The **MCP governance layer** in Molecule AI addresses all three:
+
+- Every browser action is logged with the org API key prefix that initiated it
+- Chrome sessions are token-scoped — Agent A's session is never Agent B's
+- Revocation is one API call — the key stops working, the session closes, no redeploy required
+
+---
+
+## How MCP Browser Automation Works in Molecule AI
+
+The integration uses Chrome's CDP over a WebSocket connection managed by the MCP server. Molecule AI's MCP server exposes a structured set of tools that map to CDP commands. Your agent calls these tools like any other MCP tool — the same interface whether you're automating Chrome, reading memory, or querying the platform API.
+
+Here's the sequence:
+
+1. **Workspace starts with a Chrome session attached** — the session is scoped to a specific Chrome profile or fresh browser context, isolated from other agents
+2. **Agent calls MCP tools** — `cdp_navigate`, `cdp_click`, `cdp_evaluate`, `cdp_screenshot`, and others are available as structured tools with type-safe parameters
+3. **Every call is audit-attributed** — the org API key prefix (e.g., `mole_a1b2`) is logged with the tool name, parameters, and result for every CDP call
+4. **Session is revocable at any time** — revoke the org API key and the agent loses Chrome access immediately
+
+### AI Agent Browser Control: What You Can Do
+
+**Navigation and interaction:**
+- `cdp_navigate` — navigate to any URL (supports `data:` and `about:` URLs via browser UI)
+- `cdp_click` — click a DOM element by selector
+- `cdp_type` — type text into a focused element
+- `cdp_hover` — hover over a DOM element
+- `cdp_scroll` — scroll an element or the page
+
+**Inspection and debugging:**
+- `cdp_screenshot` — capture a full-page or viewport screenshot
+- `cdp_evaluate` — execute JavaScript in the page context
+- `cdp_get_cookies` / `cdp_set_cookies` — read and write cookies for authenticated sessions
+- `cdp_get_local_storage` / `cdp_set_local_storage` — read and write localStorage
+
+**Network and performance:**
+- `cdp_get_requests` — capture and filter network requests (XHR, fetch, WS)
+- `cdp_block_urls` — block specific URL patterns to simulate adblocked environments
+- `cdp_set_throttle` — throttle network conditions (3G, LTE, offline)
+
+---
+
+## Browser Automation AI Agents: Use Cases That Actually Ship
+
+The Chrome DevTools MCP integration is most useful in workflows where browser state is the source of truth — and where audit attribution matters.
+
+### Automated Lighthouse audits on every PR
+
+A research agent runs a Lighthouse audit against every pull request in your repo. It navigates to the preview URL, captures the performance score, flags regressions below your threshold, and reports to the PM agent. Every audit run is logged with the org API key — your observability team can trace which agent ran which audit and when.
+
+```bash
+# Agent calls cdp_navigate to the PR preview URL
+# Agent calls cdp_evaluate to run Lighthouse inline
+# Agent calls cdp_screenshot to capture the score
+# Agent delegates results to PM workspace
+```
+
+### Visual regression detection
+
+An agent maintains a baseline set of screenshots for your key user flows. On every code change, it navigates to each flow, captures screenshots, and diffs against the baseline. Drift beyond your threshold opens a ticket automatically. The governance layer means your QA team can review the full history of which screenshots were captured, when, and by which agent.
+
+### Auth scraping
+
+An agent reads authenticated browser state from an existing Chrome session — cookies, localStorage, session tokens — and uses that state to authenticate API calls that would otherwise require separate credential management. The session is scoped; the credentials never leave the browser context.
+
+---
+
+## MCP Governance Layer: Why It Matters
+
+The MCP protocol gives you tool connectivity. The governance layer is what makes it enterprise-ready.
+
+### Per-action audit logging
+
+Every CDP call your agent makes generates an audit log entry. The log includes:
+
+- **Org API key prefix** — which integration made the call (e.g., `mole_a1b2`)
+- **Tool name and parameters** — `cdp_navigate(url=https://...)`
+- **Result or error** — success, timeout, or CDP error code
+- **Timestamp and workspace ID** — for timeline reconstruction
+
+This is the audit trail your security team will ask for in the next compliance review. It exists because Molecule AI's MCP server generates it — not because you built a custom logging pipeline.
+
+### Token-scoped Chrome sessions
+
+Chrome sessions are isolated per org API key. When you create an org API key for a specific integration (`lighthouse-reporter`), that key's Chrome session is separate from every other key's session. No credential cross-contamination — Agent A cannot read Agent B's authenticated state because their sessions are isolated at the MCP tool layer.
+
+### Instant revocation without redeployment
+
+If you need to revoke access — the integration is compromised, the agent behavior is unexpected, the contractor relationship ended — you revoke the org API key:
+
+```bash
+curl -X DELETE https://platform.moleculesai.app/org/tokens/<token-id> \
+  -H "Authorization: Bearer <admin-session-token>"
+```
+
+The key stops working immediately. The Chrome session is closed. The agent loses browser access before the next heartbeat. No redeploy, no container restart, no waiting for DNS cache expiration.
+
+---
+
+## Setting Up Chrome DevTools MCP
+
+Chrome DevTools MCP requires a Chrome instance running with the remote debugging port enabled, and a `chromedp` or equivalent CDP client connected through Molecule AI's MCP server.
+
+### Step 1: Enable Chrome remote debugging
+
+Start Chrome with the `--remote-debugging-port=9222` flag:
+
+```bash
+# macOS
+/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
+  --remote-debugging-port=9222 \
+  --user-data-dir=/tmp/chrome-debug
+
+# Linux
+google-chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-debug
+```
+
+### Step 2: Configure Molecule AI
+
+In your workspace config, add the Chrome DevTools MCP server URL:
+
+```yaml
+# config.yaml
+mcpServers:
+  - name: chrome-devtools
+    url: "http://localhost:9222"  # CDP WebSocket endpoint
+    transport: cdp
+```
+
+### Step 3: Verify the connection
+
+Your agent can now call CDP tools. Test with a simple navigation:
+
+```
+Agent: navigate to https://example.com and screenshot the page
+```
+
+The audit log should show `cdp_navigate` and `cdp_screenshot` entries attributed to the workspace's org API key prefix.
+
+---
+
+## What the Security Review Looks Like
+
+When your security team asks "what does this integration actually do?", here's the answer:
+
+**What it can do:**
+- Navigate to any URL (with org API key attribution on every navigation)
+- Read and write browser state (cookies, localStorage, session tokens)
+- Screenshot pages and DOM elements
+- Execute JavaScript in the page context
+
+**What it can't do (by default):**
+- Access the host machine beyond the Chrome sandbox
+- Read files outside the browser context
+- Exfiltrate session tokens across session boundaries
+
+**What revocation looks like:**
+- Revoke org API key → immediate session close
+- No redeploy, no agent restart
+- Audit trail shows every action taken before revocation
+
+---
+
+## Browser Automation Governance: The Bigger Picture
+
+Chrome DevTools MCP is one piece of Molecule AI's broader MCP governance story. MCP is a general-purpose protocol — it connects agents to any tool that speaks CDP, stdio, or HTTP. The governance layer applies uniformly: every MCP call gets the same treatment — org API key attribution, audit logging, instant revocation.
+
+This means you can add new MCP integrations — databases, APIs, code execution environments — with the same governance posture. The MCP protocol is the connectivity layer. Molecule AI's MCP governance layer is the control plane.
+
+If you're evaluating AI agent platforms for browser automation governance, the question to ask is not "can it control a browser?" It's "can I audit every action, attribute every call, and revoke access in one step?" Chrome DevTools MCP with Molecule AI's MCP governance layer is the answer to that question.

+/**
+ * MissingKeysModal
+ * ----------------
+ * Dispatches between two modes based on what the template declares:
+ *
+ *  1. PROVIDER PICKER — when the preflight returned ≥2 `providers` (e.g.
+ *     a Hermes template whose models[].required_env enumerate OpenRouter,
+ *     Anthropic, Nous-native, etc.). Radio list of options, saving the
+ *     chosen option's env vars satisfies the deploy.
+ *
+ *  2. ALL-KEYS — every entry in `missingKeys` rendered as its own input,
+ *     all must save before Deploy. Used when the template has a single
+ *     provider option or no declared alternatives.
+ *
+ * The modal never hardcodes per-runtime provider lists; the upstream
+ * preflight derives that from the template config.yaml.
