Sets up Pentad (CHARTER, CHITTY, CLAUDE) for chittymonitor and corrects chittyconnect framing (it is not being sunset, just shedding webhook handling and 1Password plumbing).

Summary by CodeRabbit

  • Documentation
    • Replaced placeholder materials with complete service, deployment, API, and operational guidance.
    • Documented GitHub webhook behavior, authentication, validation, error handling, and configuration.
    • Added beacon migration guidance, including rollout and redirect expectations.
    • Expanded security documentation covering threats, secrets, auditing, and incident response.
  • Chores
    • Updated runtime compatibility and platform tooling configuration.
    • Refreshed service documentation metadata and review information.

Migration Agent added 2 commits July 29, 2026 02:55
- CHARTER.md: mission, scope, dependencies, migration obligations
  (chittyconnect sunset, chittybeacon absorption)
- CHITTY.md: full API surface, webhook handler spec (POST /webhook/github),
  chittybeacon migration 4-phase plan, data model, known tech debt
- CLAUDE.md: agent dev instructions — worker-only architecture,
  secrets via chittysecrets, webhook impl notes, common pitfalls

Closes F-039 pentad stub. service_chittyid pending canonical mint.
chittyconnect is NOT sunset — it stays live as the orchestration,
context, session, and memory spine of ChittyOS.

What's actually moving:
- 1Password credential plumbing  → chittysecrets
- GitHub webhook handler         → chittymonitor

Updated CHARTER.md:
- 'chittyconnect sunset' → 'chittyconnect credential offload'
- Webhook item: 'absorbing' → 'offloaded'; explicit note that
  chittyconnect stays live

Updated CHITTY.md:
- secrets note: 'which is sunset' → accurate description of the
  credential migration only
- Webhook §Background: rewritten as responsibility handoff,
  explicitly not a decommission

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to b916c

This PR adds migration and security guidance, but the current text includes unsafe webhook acknowledgment and redirect behavior plus incomplete or ambiguous secret and authorization controls. Those instructions could cause lost webhook events or weaken operational safeguards, so the PR is not merge-ready until the guidance is corrected or explicitly accepted by the owners.

Protect the sweep trigger from public invocation.

GET /api/health/sweep performs 23 outbound checks plus Durable Object writes and pruning, but no authentication or rate limit is specified. Keep the cron path internal/authenticated, or make this a protected mutation/DO RPC; leave /api/health/latest as the public read endpoint.

Deduplicate GitHub deliveries before triggering side effects.

X-GitHub-Delivery is accepted but never persisted or used as an idempotency key. GitHub redeliveries can therefore create duplicate workflow rows, trigger duplicate builds, and post duplicate statuses. Add a unique delivery claim in DO storage before processing the event.

Preserve the webhook body for JSON parsing.

req.arrayBuffer() consumes the request body. If the handler verifies the signature and then calls req.json(), every valid webhook fails during parsing. Verify a captured byte buffer, or call the verifier on req.clone().

### CF Workers Builds Trigger

On `push` to a branch that matches a configured pattern (default: `main`), call the
Cloudflare Workers Builds API:

```
POST https://api.cloudflare.com/client/v4/accounts/{CF_ACCOUNT_ID}/workers/scripts/{script_name}/builds
Authorization: Bearer {CF_API_TOKEN}
Content-Type: application/json
Body: { "branch": "<branch>", "commit_hash": "<sha>" }
```

The `script_name` is resolved by matching the pushed repository slug against a
lookup table stored in the DO (see `webhook_configs` table below — to be added in
the implementation commit).

🌐 Web query:

Cloudflare Workers Builds API trigger builds authenticate with trigger ID API reference

💡 Result:

To programmatically trigger a build in Cloudflare Workers using the Builds API, you must use the Create manual build endpoint [1][2]. Authentication The Builds API requires a user-scoped API token [1]. Account-scoped tokens are not supported and will return an error [1]. The token must have the following permissions: - Workers Builds Configuration: Edit (required to trigger builds) [1] - Workers Scripts: Read (required only if you need to retrieve the Worker's external script ID) [1] Triggering a Build To trigger a build, you must send an HTTP POST request to the following endpoint [1][2]: POST /accounts/{account_id}/builds/triggers/{trigger_uuid}/builds You must provide the {account_id} and the {trigger_uuid} [2]. You can retrieve the trigger UUID for your Worker by calling GET /builds/workers/{external_script_id}/triggers [1][3]. Example Request Using curl, the request structure is as follows [2]: curl https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/builds/triggers/$TRIGGER_UUID/builds \ -H 'Content-Type: application/json' \ -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \ -d '{ "branch": "main" }' Alternatives If you do not want to manage API tokens, you can use Deploy Hooks [4]. A Deploy Hook provides a unique, unauthenticated URL that triggers a build for a specific branch when an HTTP POST request is sent to it [4]. The unique identifier in the URL serves as the authentication credential [4].

🌐 Web query:

Cloudflare Workers Builds API POST builds endswith trigger-build script_name commit_hash

💡 Result:

To trigger a build programmatically using the Cloudflare Workers Builds API, you should use the POST /accounts/{account_id}/builds/triggers/{trigger_uuid}/builds endpoint [1][2]. This method requires a trigger UUID, which acts as the target for the build request. You can obtain this UUID by listing triggers for your worker via the GET /accounts/{account_id}/builds/workers/{external_script_id}/triggers endpoint [3]. The request body for the POST /builds/triggers/{trigger_uuid}/builds endpoint accepts the following optional parameters to specify which code to build [2]: - branch: The Git branch name (required if commit_hash is not provided). - commit_hash: The specific Git commit hash (required if branch is not provided). Example request: curl -X POST "https://api.cloudflare.com/client/v4/accounts/{account_id}/builds/triggers/{trigger_uuid}/builds" \ --header "Authorization: Bearer <API_TOKEN>" \ --header "Content-Type: application/json" \ --data '{"branch": "main", "commit_hash": "abc123def456"}' Alternatively, for simpler, unauthenticated triggers, you can use Deploy Hooks. A Deploy Hook provides a unique, secret URL that triggers a build for a specific branch when an unauthenticated POST request is sent to it [4]. The URL follows the structure: https://api.cloudflare.com/client/v4/workers/builds/deploy_hooks/<DEPLOY_HOOK_ID> [4][5].

GitHub Cloudflare Workers CI/CD builds API token required Workers Builds Configuration Edit

💡 Result:

To configure CI/CD for Cloudflare Workers using GitHub Actions, you must use a Cloudflare API token to authenticate your non-interactive deployments [1][2]. You do not need an API token if you use the native Cloudflare Workers GitHub integration (managed via the Cloudflare Workers & Pages GitHub App), as that handles authentication automatically [3]. For a manual CI/CD setup using GitHub Actions and the official Wrangler CLI, follow these steps: 1. Create a Scoped API Token: In your Cloudflare Dashboard, go to My Profile > API Tokens and create a new token [4]. For basic Worker deployments, the minimum recommended permissions are Account: Workers Scripts (Edit) [2]. Avoid using your Global API Key for security reasons [5]. 2. Configure GitHub Secrets: In your GitHub repository, navigate to Settings > Secrets and variables > Actions [2]. Add the following secrets: - CLOUDFLARE_API_TOKEN: The API token you generated [1]. - CLOUDFLARE_ACCOUNT_ID: Your Cloudflare Account ID (obtainable by running wrangler whoami locally) [1][2]. 3. Update Your Workflow File: Use the official cloudflare/wrangler-action in your GitHub Actions workflow file (.github/workflows/deploy.yml) [1][6]. Ensure your step passes the API token and account ID as inputs or environment variables [1][5]: jobs: deploy: runs-on: ubuntu-latest steps: - uses: actions/checkout@v6 - name: Deploy Worker uses: cloudflare/wrangler-action@v3 with: apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }} accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }} If you are using Workers Builds (Cloudflare's native CI/CD feature), an API token is generated automatically by Cloudflare to authorize deployments [4]. If you choose to configure a custom token for Workers Builds, it must have appropriate permissions for the resources your Worker requires (e.g., Workers Scripts, KV, R2) [4].

Use the Workers Builds trigger UUID in the trigger flow.

The documented POST /workers/scripts/{script_name}/builds endpoint does not trigger a build. Use the Builds API contract: resolve the Worker’s external script ID, list its triggers to get the trigger UUID, then POST to /accounts/{CF_ACCOUNT_ID}/builds/triggers/{trigger_uuid}/builds with the push branch/commit. The secret table should capture that trigger-scoped configuration instead of only script_name and CF_ACCOUNT_ID.

Remove beacon from the sweep when the redirect goes live.

After Phase 3, the beacon health request will redirect to monitor.chitty.cc/health, so the beacon result can remain green while measuring monitor itself. Remove it at cutover, or record the redirect as a deprecation check rather than a beacon health check.

Define authentication for every mutating endpoint.

The documented service-token policy omits /track, the sync endpoints, and webhook-config management. Also, GitHub webhooks provide HMAC authentication, not CHITTY_AUTH_SERVICE_TOKEN; requiring both would reject legitimate deliveries.

Cloudflare Workers Platform limits simultaneous outgoing fetch connections response headers FetchQueue scriptThrewException

💡 Result:

Cloudflare Workers enforce a limit on simultaneous outgoing connections, which has been updated as of April 2026 to be more flexible [1][2]. Simultaneous Connection Limit Each Worker invocation can have up to six connections simultaneously in the initial "waiting for response headers" phase [1][3]. - Connections are only counted against this limit while the runtime is establishing the connection and waiting for the server to return headers [1][2]. - Once response headers have been received, the connection is no longer counted against the limit, even while the response body is being read [2]. - If a Worker attempts to initiate a seventh connection while six are already in the "waiting for headers" phase, the new request is placed into a pending queue until one of the existing connections completes its header phase [1][3]. - This change eliminated previous issues where the runtime would cancel connections due to perceived inactivity or stalling [2]. Relevant API calls that count toward this limit while waiting for headers include fetch, Workers KV operations, Cache operations, R2 storage operations, Queues (send/sendBatch), and manual TCP socket connections [1][3]. scriptThrewException The scriptThrewException (Error 1101) is an invocation status in Cloudflare's metrics and analytics that indicates the Worker script itself encountered an unhandled JavaScript exception [4][5]. - It does not specifically refer to hitting the simultaneous connection limit [4]. - This error is typically caused by issues within the code, such as unhandled promise rejections, logic errors (e.g., calling a method that does not exist), or failed operations that were not wrapped in try-catch blocks [6][7]. - If a connection limit was reached in the past, it could have caused issues that manifested as crashes or errors, but modern runtime behavior now queues these requests rather than throwing exceptions or crashing the script [2][3]. To address scriptThrewException errors, developers should monitor their worker logs and ensure that all asynchronous operations and potential failure points are properly handled using try-catch blocks or promise rejection handlers [6][7].

Fix the Workers concurrency rationale.

Workers queues fetches that exceed six simultaneous connections waiting for response headers, and response bodies are not limited from the outgoing connection tally. scriptThrewException is an unhandled JavaScript exception status, not the connection-limit behavior. Keep CONCURRENCY = 6 if desired, but document the actual limit and response-body draining behavior.

P2 Badge Preserve the request body after signature verification

When a valid webhook reaches the proposed handler, req.arrayBuffer() consumes the original request body, so any subsequent payload parsing needed to dispatch the push or pull_request event will fail with an already-used body. Since CLAUDE.md explicitly presents this as a copy-paste implementation, verify a cloned request or buffer the body once and parse that same buffer.

P2 Badge Await calls made through the Durable Object stub

Durable Object RPC calls made through env.MONITOR_AGENT.get(...) are asynchronous even when the class method itself is declared synchronously. The current getAgent() cast hides this from TypeScript, so following this instruction makes handlers serialize unresolved Promises (often as {}) rather than query results; the guide should require awaiting stub calls.

P2 Badge Point commit statuses at an implemented GET route

For every status created from this spec, the clickable target_url will issue GET /api/workflows/:id, but the documented and implemented API only provides GET /api/workflows and PATCH /api/workflows/:id. Consequently the GitHub status link leads to a 404; add a corresponding GET route or target an existing workflow details page.

The repository's AGENTS.md does not establish an agents SDK minimum; it explicitly remains a stub whose real content is TBD.

An exact response diff cannot remain zero because both services return time-dependent fields such as checked_at, and latency values can vary between consecutive requests even when their behavior is equivalent.

The stated mitigation does not match MonitorAgent.runHealthSweep(), which calls await resp.json() and therefore buffers and parses the entire untrusted response before selecting its status field. If one monitored service is compromised and returns an oversized JSON body, it can consume the Worker's memory during every sweep. Enforce a response-size limit or parse only a bounded payload before documenting this risk as mitigated.

Scripts written against the documented response will read an absent field; update the example to response_ms or rename the API field consistently.

Use a method-preserving redirect for the API migration.

The planned API includes POST /check. A 301 can cause clients to resend the request as GET. Use 307 or 308, or define explicit method-preserving redirects for each API route.

Make webhook acceptance durable before suppressing retries.

If the build or commit-status call fails before durable enqueue, a successful webhook response acknowledges the delivery and the event can be lost. Persist the delivery or work item and retry it idempotently, or return a retryable error when required processing fails. Keep the no-5xx rule only after durable acceptance.

- Line 76: Update the secrets guidance in AGENTS.md to scope the chittysecrets
and wrangler secret put requirement specifically to chittymonitor runtime
secrets. Preserve existing chittyconnect and 1Password provisioning flows,
without directing agents to remove or disable them.
- Line 77: Update the agents SDK requirement in the AGENTS SDK documentation to
use a semver floor of >=0.16.2, or clearly separate the minimum supported
version from the worker’s declared dependency range so the documented
requirement accurately includes version 0.19.0.

Scope the 1Password rule to chittymonitor.

Line 76 reads as a repository-wide prohibition. The PR objective says chittyconnect and its 1Password plumbing remain active while migration occurs. State that chittymonitor runtime secrets use chittysecrets, without instructing agents to remove or disable existing chittyconnect or 1Password flows.

Express the agents SDK requirement as a semver floor.

The worker declares agents: "^0.19.0". For a 0.x package, ^0.16.2 excludes 0.19.0. Use >=0.16.2 for a true minimum, or document the supported range separately from the declared range.
