DottaandPaperclip 20d26117c9 fix(chat): use the claimed Cloud origin for connector URLs (#13680)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Chat connectors publish callback URLs and links to the board.
> - Cloud can assign a warm instance its final origin after the server
starts.
> - The signed runtime identity already tracks that change.
> - The chat service kept a copy of the startup origin and continued to
publish it.
> - This pull request resolves the trusted origin when it creates each
URL.
> - New connector setup uses the claimed hostname without a server
restart.

## Linked Issues or Issue Description

**What happened?**

Chat setup in a claimed warm instance used its old pool hostname in
provider callbacks. Account confirmation and task links could also use
the old hostname.

**Expected behavior**

Chat URLs follow the signed canonical origin after the claim. An
explicit webhook ingress override still applies only to provider
callbacks. Self-hosted URL precedence stays the same.

**Steps to reproduce**

1. Construct the chat service with a pool origin.
2. Apply the Cloud claim without restarting the service.
3. Open Slack setup or create an account-linking intent.
4. Observe the startup hostname in the returned URL.

**Paperclip version or commit**

Reproduced on master at `9335b7db1`.

**Deployment mode**

Paperclip Cloud warm-instance claim.

Related: #12766 introduced the signed canonical runtime identity.

## What Changed

- Resolve the signed Cloud origin when building chat setup, account
confirmation, and task URLs.
- Use the same callback origin for Telegram registration and GitHub
webhook recovery.
- Preserve explicit webhook ingress and self-hosted configuration
precedence.
- Add regression coverage for existing and new endpoints across Slack,
GitHub, Teams, and Telegram.
- Document the origin precedence and the need to update callbacks
already saved at a provider.

## Verification

- Reproduced both new regression cases against the original code.
- Full chat integration and signed Cloud identity suites: 1,015 tests
passed after the production-code correction.
- Five origin and ingress cases passed after review additions, including
Telegram registration and GitHub webhook repair after a live claim.
- Focused origin, ingress, callback, task-link safety, and
tenant-isolation checks: 67 passed.
- `pnpm -r typecheck` and `pnpm build` passed. Server typecheck and
compilation passed again after the task-link validation correction.
- A broad local `pnpm test:run` started before the correction was
stopped after the final-commit CI suite passed. It is not counted as a
passing local run.
- Final-commit CI: 54 successful checks; two optional Storybook checks
skipped. Greptile: 5/5 with all review threads resolved.
- No live deployment or Slack app mutation was performed.

## Risks

- Cloud chat URLs now follow the signed runtime identity. Request host
headers cannot set this value.
- An explicit webhook ingress override still takes precedence for
callbacks.
- Existing Slack app settings are external state. Operators must replace
an old callback URL in Slack.
- This change does not deploy the app or change gateway ingress policy.
No schema migration is required.

Environment Variables Full environment variable reference

All environment variables that Paperclip uses for server configuration.

Server Configuration

Variable Default Description
PORT 3100 Server port
PAPERCLIP_BIND loopback Reachability preset: loopback, lan, tailnet, or custom
PAPERCLIP_BIND_HOST (unset) Required when PAPERCLIP_BIND=custom
HOST 127.0.0.1 Legacy host override; prefer PAPERCLIP_BIND for new setups
DATABASE_URL (embedded) PostgreSQL connection string
PAPERCLIP_HOME ~/.paperclip Base directory for all Paperclip data
PAPERCLIP_INSTANCE_ID default Instance identifier (for multiple local instances)
PAPERCLIP_DEPLOYMENT_MODE local_trusted Runtime mode override
PAPERCLIP_DEPLOYMENT_EXPOSURE private Exposure policy when deployment mode is authenticated
PAPERCLIP_API_URL (auto-derived) Paperclip API base URL. When set externally (e.g., via Kubernetes ConfigMap, load balancer, or reverse proxy), the server preserves the value instead of deriving it from the listen host and port. Useful for deployments where the public-facing URL differs from the local bind address.
PAPERCLIP_CHAT_WEBHOOK_PUBLIC_URL (board public origin) Optional HTTPS origin for native chat provider webhooks when ingress and the board use different hosts. Must have no credentials, path, query, or fragment; invalid configuration refuses startup. Used only for provider callback URLs, not board links, authentication, trusted hosts, or identity confirmation.
PAPERCLIP_RUNNER_PUBLIC_URL (unset) Explicit wss:// base URL used only when a remote paperclip_runner target dials Paperclip directly. Paperclip appends /api/runner/v1/connect/<runId>; the reverse proxy must forward WebSocket upgrades for that route. This value is never inferred from request headers. Daytona ignores it and uses provider ingress.
PAPERCLIP_RUNNER_CA_BUNDLE_PATH (unset) Optional PEM CA bundle for direct runner WSS. Platform roots remain enabled. There is no insecure TLS bypass.
PAPERCLIP_RUNNER_REMOTE_BINARY_PATH (host build) Host-local path to a paperclip-runnerd artifact built for the remote target OS and architecture. Required when Paperclip and the remote sandbox do not share a compatible platform; build metadata and the required transport mode are verified before launch.
PAPERCLIP_RUNNER_REMOTE_CODEX_PATH (unset) Optional host-local path to a Codex executable built for the remote target OS and architecture. For remote Codex-backed runners, Paperclip stages and verifies this executable beside paperclip-runnerd.
PAPERCLIP_RUNNER_REMOTE_CODEX_NPM_SPEC (unset) Optional pinned npm package spec (for example, @openai/codex@0.153.4) installed inside each fresh remote lease when its Codex harness is not baked into the sandbox image. Mutually exclusive with PAPERCLIP_RUNNER_REMOTE_CODEX_PATH; Paperclip verifies the installed executable before starting runnerd.
PAPERCLIP_RUNNER_REMOTE_PROVIDER_PACK_PATH (unset) Host-local path to the immutable provider pack built by pnpm --filter @paperclipai/paperclip-runner build:provider-pack. The pack includes its target-built Node 24.11 runtime, locked production dependencies, OpenCode proxy/executable, and ACPX sidecar. Remote OpenCode and ACPX fail closed without it. A preinstalled pack is accepted only when its complete digested manifest matches this build-owned pack; otherwise Paperclip stages this pack into the sandbox.
PAPERCLIP_HIDDEN_SETTINGS (unset) Comma-separated settings surfaces to hide from the UI and floor at the API, for operators hosting Paperclip for others (managed cloud, internal shared server). See Hiding settings surfaces.
PAPERCLIP_SETTING_DEFAULTS (unset) JSON object replacing the schema default of selected instance settings, for hosting operators. See Operator setting defaults.

Daytona connectivity for paperclip_runner uses authenticated provider WebSocket ingress and follows the instance experimental setting enableNativeRunner (default false). There is no separate ingress opt-in. Disabling Paperclip Runner blocks fresh native starts while persisted native runs retain their recovery path. The deprecated enableRunnerPreviewIngress key remains accepted in stored and managed configuration for version-skew compatibility, but it has no runtime effect. The setting has no effect on legacy adapters or callback bridges.

Webhook-only chat ingress

Keep PAPERCLIP_PUBLIC_URL (or the explicit authentication public URL) pointed at the actual board. If the board is private, set PAPERCLIP_CHAT_WEBHOOK_PUBLIC_URL=https://chat-ingress.example.com and forward only POST /api/chat-webhooks/* from that host. Provider signatures still gate ingress; this variable does not expose routes or grant provider access. Never forward the private local_trusted board through a public tunnel.

In Paperclip Cloud, chat callback URLs and account-linking URLs follow the instance's signed canonical origin after a warm instance is claimed, without requiring a restart. An explicit PAPERCLIP_CHAT_WEBHOOK_PUBLIC_URL still takes precedence for provider callbacks only; board links follow the claimed origin. Existing provider-side callback settings must be updated if they were created with an old URL.

Task links in external messages require an externally safe HTTPS board URL. Local/private board URLs are omitted with instructions to open the task in Paperclip; the public webhook host is never substituted for the board. Identity confirmation stays on the board and requires the user to be able to reach it.

Preinstalled remote runner images

Remote sandbox images may preinstall paperclip-runnerd, codex, and the provider pack at /opt/paperclip-runner/provider-pack instead of paying the upload and npm-install cost on every fresh lease. Put both executable names on the sandbox user's PATH; $HOME/.local/bin is checked explicitly before PATH. Paperclip verifies runner build metadata, the selected PRP transport capability, Codex startup, the provider-pack digest, exact harness pins, Node compatibility, and packaged bridge digests before linking artifacts into the run-specific runtime directory. A missing or incompatible executable falls back to PAPERCLIP_RUNNER_REMOTE_BINARY_PATH and PAPERCLIP_RUNNER_REMOTE_CODEX_NPM_SPEC (or PAPERCLIP_RUNNER_REMOTE_CODEX_PATH) without changing the selected transport. OpenCode and ACPX instead fall back only to PAPERCLIP_RUNNER_REMOTE_PROVIDER_PACK_PATH; they never start a provider process on the Paperclip host for a remote target. The Daytona environment editor's Configure image action can create this image without a separate container registry: install the executables in its setup sandbox, finish setup, and Paperclip captures and promotes the resulting Daytona snapshot for future leases.

Hiding settings surfaces

PAPERCLIP_HIDDEN_SETTINGS takes keys from the registry in packages/shared/src/settings-visibility.ts:

  • Any instance settings page: instance.profile, instance.environments, instance.access, instance.experimental, instance.plugins, instance.adapters — removed from navigation and routing (the General page is the settings root and stays visible). Hiding instance.access, instance.plugins, or instance.adapters also floors their management endpoints with 403 settings_operator_managed; hiding instance.experimental floors every experimental toggle write.
  • Any Instance → General section: instance.general.censorUsernameInLogs, instance.general.keyboardShortcuts, instance.general.backupRetention, instance.general.feedbackDataSharingPreference (each also rejects value-changing writes via PATCH /api/instance/settings/general), plus the UI-only instance.general.deploymentStatus and instance.general.signOut.
  • Any experimental toggle: instance.experimental.<flagKey> (e.g. instance.experimental.enableSmokeLab) — the card disappears and value-changing writes are rejected.
  • Any top-level company settings page: company.members, company.invites, company.secrets, company.export, company.import — removed from the settings sidebar, tab bar, and routing (the company General page is the settings root and stays visible). These are UI-visibility keys: the membership, invite, secret, and export APIs stay live for agents and integrations. company.import is the exception — hiding it also floors every company-import route with 403 settings_operator_managed. On cloud-managed instances import is floored unconditionally with 403 cloud_managed, independent of this variable.
  • A single tab of the Secrets page: company.secrets.vaults (Provider vaults) and company.secrets.proposals (Proposals) — the tab disappears while the rest of the page stays up. UI-visibility only; the secret provider-config and proposal APIs stay live for agents and integrations.

Unknown keys are logged and ignored, so one list can be rolled across a fleet of mixed app versions, and retired keys (like instance.heartbeats, whose page was removed) can stay in an operator list without breaking older or newer releases. With the variable unset nothing is hidden and behavior is identical to earlier releases. Hiding a toggle does not change its value; pair hiding with the desired default where it matters (for general settings, see Operator setting defaults).

Operator setting defaults

PAPERCLIP_SETTING_DEFAULTS takes a JSON object whose fields come from the registry in packages/shared/src/setting-defaults.ts (currently feedbackDataSharingPreference). The operator value substitutes for the schema default at read time: any field whose effective value is still the schema default resolves to the operator value, while an explicit non-default user choice always wins. The overlay is never persisted, so unsetting the variable restores stock behavior wherever a user has not chosen otherwise. A client that writes back the full settings object it read does not persist the operator value either: writing the operator value over a still-unchosen field is treated as an echo of the overlay and the field stays unchosen.

Example: PAPERCLIP_SETTING_DEFAULTS='{"feedbackDataSharingPreference":"allowed"}' defaults AI feedback sharing to allowed; pairing it with instance.general.feedbackDataSharingPreference in PAPERCLIP_HIDDEN_SETTINGS also hides the control and floors value-changing writes.

Unknown field names are logged and ignored (mixed-version fleet safe). Malformed JSON or an invalid value for a known field refuses startup — policy configuration fails closed.

Secrets

Variable Default Description
PAPERCLIP_SECRETS_MASTER_KEY (from file) 32-byte encryption key (base64/hex/raw)
PAPERCLIP_SECRETS_MASTER_KEY_FILE ~/.paperclip/.../secrets/master.key Path to key file
PAPERCLIP_SECRETS_STRICT_MODE false Require secret refs for sensitive env vars

Agent Runtime (Injected into agent processes)

These are set automatically by the server when invoking agents:

Variable Description
PAPERCLIP_AGENT_ID Agent's unique ID
PAPERCLIP_COMPANY_ID Company ID
PAPERCLIP_API_URL Paperclip API base URL (inherits the server-level value; see Server Configuration above)
PAPERCLIP_API_KEY Short-lived JWT for API auth
PAPERCLIP_RUN_ID Current heartbeat run ID
PAPERCLIP_TASK_ID Issue that triggered this wake
PAPERCLIP_WAKE_REASON Wake trigger reason
PAPERCLIP_WAKE_COMMENT_ID Comment that triggered this wake
PAPERCLIP_APPROVAL_ID Resolved approval ID
PAPERCLIP_APPROVAL_STATUS Approval decision
PAPERCLIP_LINKED_ISSUE_IDS Comma-separated linked issue IDs

LLM Provider Keys (for adapters)

Variable Description
ANTHROPIC_API_KEY Anthropic API key (for Claude Code adapter)
OPENAI_API_KEY OpenAI API key (for Codex adapter)
