 HTTPS URL and rewrites it to loopback. The production event transport retains
 its HTTPS, public-IP DNS pinning and no-redirect checks.
 
+## Connect a real Dot to the disposable lab
+
+The separate live lab uses the real remote webhook transport, with no synthetic
+Dot peer or callback override. It still uses synthetic task admission and one
+projected `save_report` tool, so it is a transport acceptance test, not production
+agent scheduling. It requires an existing Dot account with custom plugins.
+
+Expose **only port 43127** through an HTTPS tunnel, then run:
+
+```sh
+cloudflared tunnel --protocol http2 --url http://127.0.0.1:43127 --no-autoupdate
+DOT_LAB_ORIGIN=https://YOUR-TUNNEL-HOST pnpm prototype:dot:live
+```
+
+Add `https://YOUR-TUNNEL-HOST/mcp/paperclip` as an OAuth MCP plugin in the
+account that owns the Dot. The consent page waits for local operator approval.
+The lab prints a local `control.json` path; it contains a temporary credential,
+must stay local, and is removed when the lab stops. The separate control port
+(43128 by default) must never be tunneled. Inspect the pending client and return
+origin before approving its exact request ID:
+
+```sh
+node server/scripts/dot-runner-live-control.mjs /path/to/control.json status
+node server/scripts/dot-runner-live-control.mjs /path/to/control.json approve REQUEST_ID
+```
+
+The consent page then returns to ChatGPT. Give Dot the standing instruction
+printed by the lab, including the exact company and inbox task IDs. Wait for a
+verified `paperclip.dot.work_available` subscription in `status`, then publish
+the assignment from Paperclip's side:
+
+```sh
+node server/scripts/dot-runner-live-control.mjs /path/to/control.json queue
+node server/scripts/dot-runner-live-control.mjs /path/to/control.json status
+```
+
+The expected result is a signed event delivery, Dot reading and accepting the
+assignment, a report saying `17 + 25 = 42`, and a structured runner completion.
+A delivered webhook alone is not a passing test. `status` exposes the report,
+runner transcript and delivery outcome only over authenticated loopback.
+Keep the lab and tunnel running while ChatGPT loads the newly installed tools;
+the plugin directory can list them before Dot can invoke them. A stopped quick
+tunnel cannot be reused just by restarting the lab. A new tunnel address needs
+a plugin configured for that address and fresh OAuth consent. Restarting the
+lab also discards its OAuth client registrations and grants.
+Stop the lab with the local control command (`... control.json stop`), then stop
+the tunnel after the test. Use this command for reliable cleanup; development
+process wrappers may terminate on a signal before asynchronous cleanup finishes.
+The lab expires after two hours,
+revokes its connection on graceful shutdown, and deletes its temporary database
+and encryption key. It never opens the user's existing Paperclip database.

+Live-lab setup on 2026-10-02: the isolated server started, its public OAuth
+discovery endpoint returned 200, and unauthenticated MCP requests returned 401.
+The live script passed an explicit TypeScript check, and the 37 MCP regression
+tests passed again after changing the bridge to a structural driver interface.
+During that initial setup, no actual Dot connected or subscribed: native desktop automation was unavailable,
+and the inspected browser account showed Dot creation rather than an existing
+Dot. The temporary tunnel subsequently expired; it and the lab were stopped.
+The later attempts below used the correct existing Dot account.
+
+### Actual Dot attempt, 2026-10-02
+
+With the existing Dot open in the correct Chrome profile, the user approved
+installing the private `Paperclip Dot Lab` plugin and its lab-only OAuth grant.
+The first real callback exposed a lab bug: OAuth consent request IDs are opaque
+`pcmcp_request_` tokens, not UUIDs. The live script now validates that format.
+Restarting the disposable database also erased ChatGPT's cached public client
+registration. The exact public client ID and redirect URI were restored only in
+the verified one-company lab database; no grant or token was inserted directly.
+The normal consent and PKCE exchange then completed successfully.
+
+Chrome briefly showed `ERR_BLOCKED_BY_CLIENT`; after the user handled/retried the
+page, it showed the ordinary stale-client server error instead. The browser
+block's originating component was not identified. No browser protection was
+disabled. It should not be confused with the separately diagnosed OAuth error.
+
+Observed live results:
+
+- ChatGPT called authenticated `server/discover`, `tools/list`, and `events/list`
+  using MCP 2026-07-28; all returned HTTP 200.
+- The plugin UI showed its connected account, 10 read tools, 6 write tools, and
+  all four event definitions, including the six Dot runner actions.
+- Dot found `paperclip.dot.work_available` and recognized its argument schema.
+  Initially it reported no Paperclip action tools in its runtime, including the
+  read-only `paperclip_connection`. An explicit @ mention did not make them
+  available immediately.
+- Dot also reported that its event-subscription route requires a successful
+  read-only connection check, so the reduced event-only test could not proceed.
+- The lab observed **zero `tools/call` or `events/subscribe` requests**, zero
+  subscriptions, and zero deliveries. No assignment was queued and no report
+  was saved. This is live discovery/connection evidence, **not** an end-to-end
+  task or event-wakeup pass.
+
+The first lab and tunnel were stopped too early, revoking the temporary grant
+and deleting its database. Dot subsequently reported that the action tools had
+become available, but its connection check failed against that offline endpoint.
+This does not establish a Dot runtime incompatibility. A fresh lab and tunnel
+were connected as `Paperclip Dot Lab Retry`; the new server observed Dot calling
+`paperclip_connection` successfully. The first plugin definition remains
+installed with its expired endpoint. Production still needs the admission,
+durable mailbox, recovery and tool-authority work above.
+
+### Successful real Dot retry, 2026-10-02
+
+The replacement private plugin completed fresh dynamic client registration,
+normal OAuth consent and PKCE without manual database repairs. It used the real
+Dot in the user's Chrome account and the public HTTPS tunnel. The lab retained
+the ordinary callback verification, DNS/IP pinning and webhook signing checks.
+
+Observed server evidence (UTC):
+
+| Time | Observation |
+| --- | --- |
+| 22:16:30 | Dot called `paperclip_connection` successfully. |
+| 22:17:00 | `events/subscribe` succeeded; the verified `paperclip.dot.work_available` subscription was present. |
+| 22:17:24 | The operator queued the single assignment. Its webhook was observed as `delivered` after one attempt. |
+| 22:17:48 | Dot called `paperclip_dot_inbox` after the event, without another chat prompt. |
+| 22:17:56 | Dot read the assignment using `paperclip_dot_read`. |
+| 22:18:10 | Dot accepted it; the native Runner emitted `turn.started`. |
+| 22:18:23 | Dot called `save_report` through `paperclip_dot_tool`; the lab saved exactly one report: `Dot received the Paperclip event. 17 + 25 = 42.` |
+| 22:18:38 | Dot submitted a valid `paperclip.run_result.v1`; the Runner emitted `run.result.proposed`, `turn.completed` and `run.terminal` with state `succeeded`. |
+| 22:18:50 | `events/unsubscribe` succeeded; no subscription remained. |
+
+Dot's final chat message confirmed event receipt and completion. It could not
+confirm complete unsubscription from its client response, but the server
+independently recorded the successful unsubscribe. Removing the subscription
+also removed its delivery rows, so delivery was verified before that cleanup.
+Dot separately disclosed an accidental cloud desktop app inventory call during
+setup; it reported opening no app content and stopping immediately. This test
+proves the transport and Runner handshake, not isolation of Dot's other tools.
+
+This is a **real event-triggered, two-way transport acceptance pass** using the
+new Runner backend. It still uses synthetic admission, one disposable task and
+one projected tool. It does not establish production scheduling, recovery,
+budget enforcement, arbitrary personal API operations, or reliable remote stop.
+The replacement lab was left running for inspection under its two-hour expiry;
+the test subscription was removed and no further assignment was queued.

+# OpenAI Dot with Paperclip Runner
+
+OpenAI Dot is an experimental provider of `paperclip_runner`. A dedicated
+agent OAuth connection and MCP Events wake an existing Dot. The Rust Runner
+owns the assignment lifecycle and durable tool receipts. Dot uses Paperclip's
+existing agent permissions and task tools, including document writes and
+completion feedback.
+
+This first version supports a self-hosted instance with a local Runner
+controller and a stable public HTTPS origin. Hosted agent-broker and remote
+controller deployments are not qualified. The feature is off by default.
+
+## Enable and pair
+
+1. Configure `PAPERCLIP_PUBLIC_URL` to the instance's stable HTTPS origin and
+   enable Public MCP and Paperclip Runner in experimental settings. Set
+   `PAPERCLIP_ENABLE_OPENAI_DOT=1` on the server.
+2. Create an approved Paperclip Runner agent with provider **OpenAI Dot**.
+   Acknowledge that its provider billing is external and unmetered. Save it.
+3. In the agent configuration, choose **Pair Dot**. Connect a private ChatGPT
+   plugin to the displayed `/mcp/runner` URL and approve its dedicated agent
+   OAuth scope. The personal `/mcp/paperclip` connection cannot execute as Dot.
+4. Give the Dot the one-use pairing code. It calls `paperclip_dot_pair`, then
+   subscribes to `paperclip.dot.mailbox_updated` with the returned company and
+   binding IDs. Its callback must pass the signed webhook verification.
+5. Choose **Test event delivery**. Dot drains `paperclip_dot_inbox` and confirms
+   the readiness challenge. Readiness requires this round trip, not just an
+   HTTP acknowledgement from the callback.
+6. Assign a task to the agent. Normal scheduling, checkout, company access,
+   budgets and approval rules still determine admission.
+
+Only the operator's one-use pairing code is displayed. OAuth tokens and callback
+signing secrets stay on the server and never enter the Runner descriptor,
+task prompt or saved adapter config. Pairing codes expire after 15 minutes.
+
+## Assignment protocol
+
+Events contain mailbox references. Dot drains the inbox after its saved cursor,
+reads the assignment, and explicitly accepts it before executing tools. A
+webhook `2xx` does not mean Dot accepted or started the task. Duplicate or
+out-of-order events must not create another assignment.
+
+Dot invokes catalogued tools through `paperclip_dot_tool`. Every operation uses
+a UUID request ID. A pending response is reconciled with
+`paperclip_dot_operation_status` or retried with **the same ID and arguments**.
+Changing arguments under the same ID is rejected. An unknown write must never
+be retried under a new ID.
+
+Dot calls `paperclip_finish` or `paperclip_block` through the tool bridge, then
+ends the external turn with `paperclip_dot_finish` using exactly the accepted
+structured report. Paperclip's ordinary result and status finalizers decide
+the task disposition. Dot can also discover its assigned tasks and request
+normal admission with `paperclip_dot_tasks` and `paperclip_dot_request_work`.
+
+## Limits and recovery
+
+- One active assignment per binding. Acceptance expires after 10 minutes;
+  execution authority expires after two hours. Fifteen minutes without useful
+  activity is shown in the connection panel as requiring attention.
+- No mounted workspace, selectable model, native Dot thread identifier,
+  provider usage or provider cost. Text deliverables use Paperclip documents.
+  Assigned skill files and third-party MCP bindings are currently unsupported
+  and fail admission explicitly.
+- Cancel, pause, reassignment and revocation fence Paperclip authority. They do
+  not confirm that Dot stopped all external activity. A fence acknowledgement
+  records receipt only.
+- Controller recovery restores the same bridge and assignment. A missing or
+  invalid advertised checkpoint requires reconciliation. Automatic bounded
+  retries do not create replacement Dot assignments. A tool effect still in
+  flight when its controller detaches stays pending if its exact outcome was
+  not durably recorded; recovery does not execute that write again.
+- Keep the public origin stable. Subscriptions expire and must be renewed;
+  reconnection drains current mailbox references rather than claiming event
+  replay. Disabling new Dot work does not grant old assignments new authority.
+
+## Verification evidence
+
+`server/src/__tests__/dot-runner.test.ts` uses an isolated PostgreSQL database,
+real Rust Runner, dedicated PKCE OAuth, a signed synthetic callback, normal
+semantic authority, a document write and the ordinary status finalizer. It
+checks duplicate writes, changed-argument rejection, membership loss and
+revocation. Runner tests cover bridge reattachment, missing checkpoints,
+closed launch fields, expiry and late effect receipts after fencing.
+
+The earlier real-Dot account experiment proved OAuth and signed wake/report
+transport through the reference harness; see `dot-runner-prototype.md`. That
+proof does not qualify this new dedicated endpoint against a real account.
+The dedicated adapter's account acceptance test remains to be run. The new
+connection UI has passed compilation and token gates; it has not yet received
+a hands-on browser acceptance test.
+
+Local verification on 2026-10-03:
+
+| Check | Result |
+| --- | --- |
+| `pnpm -r typecheck`, `pnpm build`, UI token gates | Passed |
+| Rust workspace library tests | 312 passed |
+| PRP schema tests and CI shard selection tests | 13 and 24 passed |
+| Control-plane and Dot driver regression tests | 97 passed, including late callback retirement |
+| Real Rust / PostgreSQL Dot integration | 2 passed |
+| Agent configuration route tests | 36 passed, including unpaired create and conversion |
+| Stable shared package lane | 837 passed |
+| Adapter utilities and Codex adapter source tests | 1,883 passed, 12 skipped |
+| Root `pnpm test:run` attempt | Server group: 744 files passed, 2 failed, 4 skipped; 14,997 tests passed. Wrapper stopped at that failed group. |
+
+The root run's failures were a Calendar socket reset and a Git scan load
+assertion (497 of 498 expected joined requests). Both failing cases passed in
+isolation. A subsequent stable database lane passed 126 tests but failed one
+embedded PostgreSQL startup; that test also passed in isolation. These results
+do not establish a completely green repository suite or release readiness.

+# OpenAI Dot as a production Paperclip Runner provider
+
+Date: 2026-10-02
+
+Status: Experimental self-hosted adapter implemented; real-account acceptance and extended context projection remain unqualified
+
+Branch: `codex/dot-events-prototype`
+
+Scope: Original production design with the implementation status recorded below. The adapter remains off by default.
+
+## Implementation status
+
+Implemented the dedicated agent OAuth resource, one-use pairing and readiness
+challenge, scoped durable mailbox and operation receipts, PRP v3 external
+operations, native input v6 without a workspace or credentials, Rust Dot
+executor, normal task tool/completion authority, provider configuration and
+connection UI. Tests exercise the real Rust Runner and ordinary task status
+finalizer, plus bridge reattachment and missing-checkpoint refusal.
+
+The current supported deployment is self-hosted with a local controller and
+stable public HTTPS. A fresh real-Dot account test of `/mcp/runner` remains
+required before qualification. The earlier account proof covers the reference
+harness's transport only. The complete fault matrix and hosted agent-broker
+qualification below remain future qualification work.
+
+Assigned skill files and third-party MCP bindings are explicitly rejected in
+this version. Automatic approval review blocked their projection to the
+external Dot because it required explicit authorization to expose those
+additional contents. Existing Paperclip semantic tools and admitted agent
+instructions remain available. See [the adapter runbook](../openai-dot-runner.md).
+
+## 1. Recommendation
+
+Add **OpenAI Dot** as a provider of the existing `paperclip_runner` adapter:
+
+```json
+{
+  "adapterType": "paperclip_runner",
+  "adapterConfig": {
+    "provider": "openai_dot",
+    "dotBindingId": "<server-owned binding>",
+    "lifecycleMode": "per_turn"
+  }
+}
+```
+
+The provider uses MCP Events to notify an existing Dot and authenticated MCP
+tools to receive its actions. Rust `runnerd` owns the provider state machine and
+PRP lifecycle. Paperclip owns connection authorization, durable mailboxes,
+admission, tool effects, budgets, approvals, and final task disposition.
+
+The implementation is a new Runner provider, not a new legacy `execute()`
+adapter. Keep `paperclip_runner` in the server/UI/CLI registries. The older
+`create-agent-adapter` skill remains useful for configuration, diagnostics and
+cross-surface consistency; its process-spawning package recipe does not define
+this provider's execution architecture.
+
+Assume the public MCP foundation from the referenced gateway work is merged.
+The prototype worktree includes that foundation at `a88448f77`. This assumption
+does not imply that the companion Cloud broker is deployed or qualified.
+
+### Evidence and limits
+
+The real-Dot test on October 2 demonstrated:
+
+1. Private custom-plugin installation and ordinary OAuth connection.
+2. Dot successfully calling `paperclip_connection`.
+3. A verified MCP Events subscription and signed webhook delivery.
+4. Dot fetching and accepting an assignment without a second chat prompt.
+5. Dot invoking a projected tool and saving exactly one test report.
+6. A valid structured result, native `turn.completed`, and `run.terminal` with
+   state `succeeded`.
+7. Server-confirmed unsubscription.
+
+The native test used TypeScript `HarnessDriverBackend`, synthetic admission,
+an in-memory driver registry and one synthetic tool. It did not exercise Rust
+runnerd, normal task checkout/finalization, restart recovery, usage accounting,
+or workspace execution. Those are implementation requirements below.
+
+The test also exposed two onboarding details: action tools may become available
+after their directory listing appears, and restarting a disposable lab destroys
+OAuth state. A stable deployment and a real readiness check are essential.
+
+## 2. Product contract
+
+### Paperclip initiates work
+
+A user selects **Paperclip Runner → OpenAI Dot**, connects their Dot, and assigns
+it an ordinary task. Existing scheduling admits the task. Paperclip sends a
+small event; Dot retrieves the current assignment, explicitly accepts it, uses
+the projected tools, and submits its result. The task thread shows delivery,
+acceptance, progress, outputs, and completion separately.
+
+Paperclip can enqueue work whenever its ordinary rules allow. Delivery and
+execution are asynchronous. A webhook acknowledgement is never presented as
+proof that Dot started work.
+
+### Dot initiates interaction
+
+Preserve both directions and make the acting identity explicit:
+
+| Context | Authority | Supported behavior |
+| --- | --- | --- |
+| User asks their Dot to use Paperclip | Existing personal MCP connection | Read company work, create/delegate tasks, add feedback, retrieve results; actor is the consenting person. |
+| Dot executes an assigned Runner turn | Dedicated agent connection plus admitted assignment | Invoke the same authorized semantic tools as another Runner provider; actor is the assigned agent and run. |
+| Dot wants to start work while idle as the agent | Dedicated connection's `request_work` operation | Submit a bounded wake request referencing an authorized task and intent. Normal scheduling decides whether to admit a run before exposing its mutation tools. |
+
+Idle `request_work` must support a company-scoped planning/intake task for
+agent-initiated ideas, so proactive work does not depend on an already assigned
+engineering task. The intake task is an ordinary governed work object, created
+through existing task rules; it is not the event mailbox or an execution bypass.
+Actual task creation, delegation and writes then use the admitted tool catalog.
+
+Do not silently give an agent the consenting person's authority. A personal
+connection remains optional and independent. If the same Dot also has personal
+Paperclip access or other plugins, Paperclip cannot prevent it from acting
+through those separately authorized channels. Users needing strict separation
+must use a Dot/account without those broader connections.
+
+### First release boundaries
+
+- One active assignment per binding. Additional tasks remain in normal queues;
+  do not admit a large backlog into provider sessions waiting for acceptance.
+- One active agent binding per dedicated OAuth grant. Multi-agent multiplexing
+  through one Dot connection is deferred.
+- Standard, planning and ask tasks use normal Paperclip tool policy. Only
+  capabilities actually exposed to this provider are offered.
+- Start with control-plane work: research coordination, task decomposition,
+  documents, comments, approvals and assigned connector tools. A Dot is not
+  presumed to share the Paperclip repository or local filesystem.
+- Follow-up messages are durable task messages and subsequent assignments.
+  Active steering is unavailable in v1. The UI must say when a message is queued.
+- Model selection, token usage, provider-native session reset, private reasoning,
+  global interruption, and control of Dot's other tools are unavailable.
+- Public reachability is required. No Chrome automation, ChatGPT cookies,
+  undocumented task endpoints, or expiring development tunnels in production.
+
+## 3. Architecture and ownership
+
+```mermaid
+sequenceDiagram
+  participant App as Paperclip scheduler/controller
+  participant Runner as Rust runnerd: Dot provider
+  participant Broker as Durable Dot mailbox + public MCP
+  participant Dot as OpenAI Dot
+  App->>Runner: Authenticated PRP prepare/open/start

+```
+
+The apparent round trip through the controller is intentional: MCP is the
+provider's transport, while Runner remains the execution lifecycle. Avoid a
+second tool dispatcher or finalizer hidden in the MCP route.
+
+### Component responsibilities
+
+| Component | Owns | Must not own |
+| --- | --- | --- |
+| Public MCP/OAuth | Authenticate each call, resource/scope checks, bounded input, callback verification | Creating an admitted run from supplied IDs; arbitrary agent impersonation |
+| Dot broker in server | Pairing, bindings, mailbox, delivery state, request deduplication, routing to the current controller | Domain effects or provider terminal decisions |
+| Rust Dot provider | Turn acceptance, provider command ordering, projected-call mapping, durable provider receipts, PRP events and checkpoints | DB access, company policy, OAuth secrets, issue status writes |
+| Existing native controller | Admission, PRP ownership/leases, semantic dispatch, governed waits and finalization | Pretending a webhook receipt proves execution |
+| Dot | Retrieve work, perform reasoning, invoke exposed tools, propose result | Selecting its company/agent/run authority or bypassing finalization |
+
+Runner receives no ChatGPT credential, MCP OAuth token, webhook URL/signing key,
+or unrestricted Paperclip API key. Reuse the authenticated PRP connection for
+the app-owned broker port. Do not add a second generic HTTP control API solely
+to get operations into runnerd.
+
+The Runner package remains standalone: define the broker port and envelopes in
+the package; implement them in Paperclip server without importing server or DB
+code into `packages/paperclip-runner`.
+
+## 4. Production Runner integration
+
+### Provider identity and configuration
+
+Proposed identifiers:
+
+- Provider: `openai_dot`.
+- Driver: `openai_dot_mcp`.
+- Execution kind: `remote_service`; the local runnerd process is only the
+  controller-side transport, not the Dot's execution process.
+- Service: `openai_dot`.
+- Provider session ID: `null` unless a documented provider identity becomes
+  available. A user-entered Dot URL is a display link, not authentication.
+- Model: `null`, displayed as **Managed by Dot**.
+- Provider version: our qualified bridge/protocol revision, clearly labelled;
+  do not claim it pins OpenAI's hosted implementation.
+
+Agent config contains only binding references and validated operational limits.
+The server resolves the binding into an immutable per-run snapshot containing
+company, agent, connection, binding generation, catalog revision, deadlines and
+protocol revision. Tasks cannot override that identity or supply callback URLs.
+
+### Contract changes
+
+The current native input is a closed `paperclip.native-execution-input.v5`
+contract. Introduce the next input revision with a Dot provider variant; retain
+v1–v5 parsing and recovery for existing providers. Update JSON Schema,
+TypeScript and Rust together, plus export/compatibility manifests and fixtures.
+Do not repurpose a Codex or ACPX profile.
+
+The new input must also distinguish provider workspace access from the Runner's
+own state directory. Dot's workspace-access variant is `none`; it receives no
+provider cwd. Adapt the execution-input builder and filesystem preparation
+guards accordingly instead of satisfying existing mandatory cwd fields with a
+made-up project path. A project/task may still exist in Paperclip without its
+checkout being mounted into this provider.
+
+Add a small, versioned external-provider transport extension over PRP. Proposed
+logical messages, with final names fixed in the contract PR:
+
+| Direction | Message | Meaning |
+| --- | --- | --- |
+| Runner → controller | `external_provider.dispatch_requested` | Persist a particular assignment/mailbox revision and notify its bound connection. |
+| Controller → Runner | `external_provider.operation` | Deliver a validated accept/tool/progress/finish/control-ack operation with its stable request identity. |
+| Runner → controller | `external_provider.operation_settled` | Persist the exact accepted/rejected/pending/unknown/result receipt for that operation. |
+
+These are closed provider-neutral transport envelopes, not raw OpenAI messages.
+Bind every envelope to company, agent, run, session, turn, binding generation,
+assignment revision and request digest. Negotiate the new command/event schema
+revision and capability explicitly; older binaries reject it before execution.
+The existing v2 enums cannot be expanded invisibly in persisted old contracts.
+
+Reads of assignment/receipt projections may come directly from the authorized
+broker database. Mutating lifecycle operations enter the live Runner. Normal
+`semantic_tool` dispatch, `paperclip_finish`/`paperclip_block` validation,
+completion feedback and PRP finalization remain authoritative.
+
+Command acknowledgement means the external operation was durably admitted to
+the Runner, not that its tool effect finished. A tool operation must release
+the command-processing lane while waiting for `semantic_tool.result`; otherwise
+the result command would deadlock behind the operation waiting for that result.
+Settlement is a separate correlated event, preserved across reconnects.
+
+### Rust and TypeScript surfaces
+
+- Add `dot_provider_backend.rs` and bounded Dot provider checkpoint/state code
+  in `runner/crates/runner-core/src/`.
+- Extend `NativeProviderCommandExecutor` selection and recovery. Detect a Dot
+  checkpoint alongside the existing Codex/ACPX/managed state; conflicting
+  provider checkpoint authorities must fail closed.
+- Reuse `ProviderToolBridge` for catalog validation, semantic call identities,
+  bounded pending/results and retained receipts.
+- Add the production Dot branch to the native backend factory and the runnerd
+  transport facade. Existing names such as `createRunnerdCodexTransport` carry
+  several providers today; extend the real provider switch rather than routing
+  Dot through a standalone TypeScript fallback.
+- Evolve `DotHarnessDriver` into the TypeScript reference/conformance
+  implementation of the same durable contract. The current memory-only lab
+  remains explicitly a lab until replaced by that implementation.
+- Teach native execution preparation and projection about **waiting for Dot**.
+  Audit the Codex defaults in `prepare-native-run.ts` so persisted profile,
+  driver identity and initial phase match the admitted Dot provider.
+- Run the lightweight Dot provider controller on the trusted execution host in
+  v1. Do not provision a code sandbox just to wait for a remote Dot. Remote
+  runner placement is a separate qualified deployment profile.
+
+### Capabilities reported to Paperclip
+
+| Capability | v1 behavior |
+| --- | --- |
+| Typed events / structured result | Supported for bridge-observed actions and validated results. |
+| Dynamic tools | Supported through current run-owned projection and normal dispatch. |
+| Read / reconciliation | Supported for durable mailbox, operation and Runner state. |
+| Native provider session resume | Unsupported; no documented Dot thread/session API. |
+| Bridge recovery after restart | Required; recover the same assignment and receipts, not a new Dot conversation. |
+| Steering / immediate interruption | Unsupported. |
+| Queued follow-up | App queue supported; do not advertise provider-native steering/follow-up guarantees. |
+| Usage / cost / model controls | Unknown or unavailable; never zero-filled or inferred from elapsed time. |
+| Native skills/MCP injection | Unsupported; expose assigned knowledge/tools through authenticated reads and projection. |
+| Native runtime permission/input control | Unsupported; use Paperclip's durable task interactions and response wakes. |
+| Goals / child-thread lineage | Unsupported. |
+
+The capability model must distinguish recovering our bridge from resuming an
+OpenAI session. Add an explicit recovery/stop description if the current booleans
+cannot express this, rather than setting `resume` or `interruption` to true.
+
+## 5. Authorization and pairing
+
+### Dedicated agent OAuth resource
+
+Add a dedicated agent resource, proposed `/mcp/runner`, sharing the existing
+OAuth/DCR/PKCE implementation and event transport. Its grant has a distinct
+purpose and `paperclip:agent` scope, optionally with `offline_access`. It never
+implicitly grants personal `paperclip:write` authority.
+
+The existing `/mcp/paperclip` resource and its personal consent semantics stay
+intact. Make the principal a discriminated personal/delegated-agent type; do not
+manufacture a board actor in an agent call. Recheck the grant's consenting user,
+membership, company availability and explicit agent delegation on every call.
+Update discovery and token audience checks for each exact resource.
+
+Pairing sequence:
+
+1. An authorized operator selects an existing/new Dot agent and starts setup.
+   Apply the normal hiring/configuration approval rules.
+2. Paperclip creates an expiring one-use pairing intent bound to company,
+   agent, initiating operator, requested delegation and protocol revision.
+3. The user installs/connects the dedicated Dot runner plugin using OAuth and
+   explicit agent consent. No agent API key is pasted into a prompt.
+4. A generated setup instruction asks Dot to complete pairing, perform a
+   read-only connection check, and subscribe to the exact binding mailbox.
+5. Pairing consumes the one-use intent and binds the grant. Callback verification
+   associates the subscription with that binding generation.
+6. A harmless challenge travels through the same event → MCP → Runner path.
+   Ready means the challenge completed, not merely that tools were listed.
+
+Store only a hash of the pairing code, bound to the initiating user and company.
+Reject expired/replayed codes, cross-company grants, duplicate active bindings,
+and any attempt by a personal grant to claim agent tools automatically.
+
+OAuth identifies an authorized client connection, not cryptographically a
+particular Dot chat. The callback identifies the subscription destination; it
+does not prove exclusive possession by one model or thread. Treat the binding
+as delegated connection authority and state that limitation in the product.
+Enforce one active assignment even if two chats use the same connection.
+
+### Per-operation authority
+
+Before accepting or replaying an operation, check:
+
+- resource, grant purpose/scopes, active membership and agent binding;
+- company, agent, assignment, run, session and turn;
+- binding generation, current assignment revision and authority deadline;
+- active controller lease/fence and task ownership;
+- agent/company pause, budget admission and applicable work-mode restrictions;
+- current projected tool permission, grants and governed approvals.
+
+Recheck at the domain mutation boundary and before returning sensitive results.
+Revoked authority must not obtain cached results simply because its request ID
+is valid. A current authorized operator can reconcile retained outcomes.
+
+Revoking/replacing a binding increments its generation and fences all old
+callbacks. Fresh consent creates a new binding generation; it never silently
+adopts active work from an older connection.
+
+## 6. Durable state and event delivery
+
+Use additive, company-scoped tables. Final naming can follow existing schema
+conventions, but these ownership boundaries are required:
+
+| Record | Key data and constraints |
+| --- | --- |
+| `dot_agent_bindings` | Company, agent, consenting user, dedicated grant, generation, readiness, protocol revision, created/revoked timestamps. Unique active agent binding and active grant binding. |
+| `dot_runner_assignments` | Immutable run/session/turn and completion-contract binding, binding generation, catalog digest, prompt/runtime-context references, status, deadlines and accepted/completed timestamps. Unique run/turn; at most one live assignment per binding. |
+| `dot_runner_operations` | Assignment, request ID, operation, canonical input digest, PRP command/call IDs, status and bounded result/reference. Unique request ID within assignment; no silent argument changes. |
+| `dot_mailbox_items` | Durable actionable item for assignment, continuation, pending tool result or control request; immutable ID, assignment revision, visibility/consumption state and stable notification identity. |
+
+Do not duplicate canonical task comments, documents, transcripts, result rows or
+finalization decisions in these tables. Store references and bounded transport
+snapshots only. Callback secrets remain in the existing encrypted event store;
+OAuth tokens remain hashed at rest. Restrict sensitive assignment/result
+retention to the same authorized data and storage policy as normal native runs.
+
+Reuse `mcp_event_subscriptions` and `mcp_event_deliveries`. Their current
+task-only subscription and activity-log scan are insufficient for a real agent
+mailbox. Add a tagged resource binding (`task` or `dot_binding`) and a typed
+mailbox notification source, with constraints so a row cannot represent both.
+Preserve current task-event authorization and behavior. Delivery uniqueness must
+cover subscription + source notification, not just an incidental task comment.
+
+No synthetic inbox issue is needed for the production transport. Activity
+logging records mutations, but an arbitrary `activityLog` row must not be able
+to manufacture a Runner assignment.
+
+### Event definition
+
+Use one production event, proposed `paperclip.dot.mailbox_updated`, filtered by
+`companyId` and `bindingId`. The prototype's task-filtered
+`paperclip.dot.work_available` stays a lab contract; migrate setup instructions
+explicitly rather than changing its schema in place.
+
+The event carries only bounded references: binding generation, mailbox item ID,
+assignment/run/turn references where applicable, item kind and mailbox revision.
+No prompts, company secrets, document bodies or authority-bearing bearer tokens.
+Dot reads current state through authenticated tools; event text grants no rights.
+
+Commit the assignment/mailbox item and notification intent atomically after
+admission. Publish only committed, currently authorized work. Reuse signed
+verification, public-IP checks/DNS pinning, no redirects, encrypted callback
+material, secret rotation, bounded retries and `410`/`413` handling.
+
+Delivery success, Dot acceptance and Runner completion are separate durable
+facts. Keep an audit-safe delivery summary attached to the assignment even if
+unsubscription removes transport rows; the lab demonstrated why that matters.
+
+### Subscription gaps and duplicates
+
+- Follow the protocol's `refreshBefore`; surface expiration/disconnection.
+- Do not promise replay while the server returns `cursor: null`.
+- On initial subscription or verified resubscription, atomically arrange a new
+  wakeup for each still-actionable mailbox item. The item/assignment ID remains
+  the same. Reconnection must neither lose old work nor create a second run.
+- Webhook retries preserve event ID. A deliberate reconnect/reminder notification
+  has its own event ID but refers to the same mailbox item.
+- Dot drains a bounded page of actionable items after a wakeup, acknowledging
+  items individually. Batched, duplicate and out-of-order events are expected.
+- Never generate another wakeup merely because Dot reported progress or posted
+  a comment. Prevent self-wake and completion-comment loops.
+
+## 7. Operation protocol and idempotency
+
+Retain the prototype's conceptual operations and add pairing/status support.
+Schemas are versioned, bounded and validated before persistence.
+
+| Operation | Behavior |
+| --- | --- |
+| Connection/pairing | Read readiness or consume a one-use pairing intent; cannot create an admitted task run. |
+| Inbox/read | Return only current bound work, prompt context, tool catalog references and completion contract. |
+| Accept | Atomically claim the current assignment once; only Runner acceptance emits `turn.started`. |
+| Tool | Map a stable external operation into a normal semantic tool call. |
+| Progress | Append bounded progress through PRP; apply ordinary useful-progress/watchdog rules. |
+| Finish | Propose the canonical structured result; run normal completion feedback and finalization. |
+| Operation status | Read a durable pending/completed/rejected/unknown receipt without redispatch. |
+| Request work | Create an idempotent ordinary wake request while idle; never self-assign by accepting arbitrary IDs. |
+| Control acknowledgement | Record cooperative acknowledgement without claiming global provider shutdown. |
+
+Use `requestId` plus assignment binding as the external operation identity. The
+server reserves it before routing to the current controller. Canonical input
+digest mismatch is an explicit conflict. Derive stable PRP command and semantic
+call IDs from that identity and preserve them across recovery.
+
+The broker receipt and existing semantic effect receipt have different jobs:
+the former tracks delivery of a provider operation; the latter proves the
+domain effect. Reuse `PaperclipRunnerToolAuthority` and its mutation receipts.
+Do not implement writes by calling the public personal MCP executor.
+
+### Lost replies and slow operations
+
+Wait only a bounded interval for an MCP response. If work is still durably
+pending, return an operation reference. A later mailbox result item wakes Dot
+when the receipt settles. A status read or retry with the same ID can also
+retrieve it. This is operation reconciliation, not polling the inbox for work.
+
+Distinguish:
+
+- **Pending:** a durable operation is still being processed; do not dispatch it
+  again merely because the HTTP request ended.
+- **Completed/rejected:** exact recorded result can be returned to a currently
+  authorized retry.
+- **Unknown:** an effect may have happened without a confirmed receipt. Block
+  redispatch, including restart recovery, until the existing domain receipt or
+  authoritative resource resolves it.
+
+No exactly-once claim for arbitrary remote writes. Use at-least-once transport
+with durable identity, existing domain idempotency and explicit uncertainty.
+Receipt exhaustion stops admission rather than evicting IDs still replayable.
+
+Finish shares the same ledger. A duplicate result cannot create another
+terminal or finalize twice. Changed completion content under the same ID is a
+conflict. A stale contract revision returns actionable feedback instead of
+marking the task done. The production path requires real criterion bindings;
+the lab's empty completion criteria are not its production contract.
+
+## 8. Lifecycle, recovery and cancellation
+
+### Assignment state
+
+```mermaid
+stateDiagram-v2
+  [*] --> Queued: normal scheduling
+  Queued --> Offered: admission + durable dispatch
+  Offered --> Accepted: explicit current-generation accept
+  Accepted --> Running: first execution activity
+  Running --> AwaitingInput: governed wait
+  Running --> ResultProposed: finish
+  ResultProposed --> Settled: normal finalizer
+  Offered --> Fenced: cancel / expire / revoke
+  Accepted --> Fenced: cancel / expire / revoke
+  Running --> Fenced: cancel / expire / revoke
+  Fenced --> Reconciliation: drain in-flight effects
+  AwaitingInput --> Settled: yielded turn
+  Settled --> [*]
+```
+
+An answered interaction produces a new, ordinarily admitted continuation with
+current context and a new authority epoch. Do not hold a network request open
+through a human approval. Dot's memory may persist, but it must read the new
+Paperclip assignment and contract before taking further actions.
+
+Suggested initial operational defaults, configurable by operators and subject
+to qualification: one active assignment, ten-minute acceptance deadline,
+two-hour maximum authority lifetime, and attention after fifteen minutes
+without useful activity. A warning is not automatic reassignment. Silence can
+mean Dot is doing external work; it does not prove termination.
+
+Successful webhook receipt without acceptance gets no unbounded reminder loop.
+At the acceptance deadline, show a recoverable connection/acceptance failure.
+An operator retry republishes a wakeup for the same still-valid assignment or
+creates a fenced successor only after reconciliation. Transport failures use
+the existing bounded delivery retry policy.
+
+### Crash matrix
+
+| Failure point | Required recovery |
+| --- | --- |
+| Before assignment commit | No event exists; ordinary admission can retry its stable intent. |
+| After commit, before send | Event worker finds the durable notification. |
+| After webhook receipt, before accept | Same assignment remains offered; do not synthesize a started turn. |
+| During accept / response lost | Same request returns the accepted receipt; one `turn.started`. |
+| Tool committed, response lost | Reconcile existing semantic receipt; never repeat the effect with a fresh ID. |
+| Paperclip controller restarts | Restore current lease/generation, route persisted operations, replay PRP acknowledgements. |
+| runnerd restarts | Restore exact Dot provider checkpoint; verify binding/catalog/assignment identities before replay. |
+| Both restart | Reconcile server records and Runner checkpoint by identity/digest; unresolved divergence becomes operator-visible, not a new assignment. |
+| Subscription expires | Preserve pending work; mark delivery unavailable; wake actionable items after verified reconnection. |
+| OAuth/binding revoked | Reject callbacks and cached-result access; retain authorized audit/reconciliation state. |
+| Old Dot continues after replacement | Reject all old-generation mutations and results. |
+| Storage/replay limit exceeded | Stop accepting new operations, retain uncertainty, surface actionable recovery. |
+
+The existing controller generation and provider-attempt counter stay distinct
+from the Dot binding generation. A server failover does not automatically
+create a new provider attempt or grant new authority to a remote model.
+
+Enforce generation/lease comparisons atomically when routing and mutating state;
+an in-memory check followed by an unfenced write is insufficient across server
+replicas. The broker stores a pending accept reservation, and projects it as
+accepted only from the Runner's durable acceptance evidence.
+
+### Stop semantics
+
+Pause, cancel, budget stop, reassignment and revocation first fence Paperclip
+authority in the same governed path used by other providers. Prevent new tool
+dispatch, hide obsolete inbox work, and reconcile already dispatched effects.
+Optionally send a cooperative stop mailbox item while the connection remains
+authorized for that narrowly scoped acknowledgement.
+
+Represent these facts separately:
+
+1. Paperclip authority revoked.
+2. Paperclip-controlled effects settled or unresolved.
+3. Dot acknowledged the stop request, if observed.
+4. OpenAI/global external activity stopped: **unconfirmed**.
+
+Killing runnerd does not kill Dot. A model acknowledgement does not prove that
+its child tasks or other plugins stopped. Do not let existing PID/process-death
+recovery logic treat either as a safe global replacement proof.
+
+After fencing and settling Paperclip effects, the run can record cancellation
+of Paperclip participation. Automatic replacement after an accepted assignment
+remains disabled where external activity might duplicate work. Surface the
+uncertainty and require the existing operator recovery path for such cases.
+
+## 9. Tools, context, files and accounting
+
+### Runtime context
+
+Build assignments through the existing native execution-input constructor,
+including task/wake context, agent instructions, completion contract, current
+questions and policy. Add read-on-demand projected operations for assigned skill
+content and large context; pin revisions and recheck authorization on reads.
+
+Use existing deferred tool discovery when catalogs exceed transport limits.
+Expose the core task tools and assigned connector tools through the same
+`PaperclipRunnerToolAuthority` and assignment snapshot used by other providers.
+An old catalog does not preserve revoked grants.
+
+Do not export local environment variables, credential bindings' secret values,
+absolute host paths or a general-purpose server shell to Dot. Instructions to
+respect a work mode do not replace server-side tool policy.
+
+### Workspaces and deliverables
+
+In v1, Dot has no shared filesystem. Suppress filesystem-dependent tools unless
+their execution location and authority are explicitly supported. A local path
+reported by Dot is never a path on the Paperclip server. Do not synthesize a
+fake cwd or pass it to existing file-upload helpers.
+
+Support durable text/Markdown outputs through existing document tools. For
+binary outputs, design a separate bounded, authenticated artifact-ingress
+contract or a qualified remote-workspace file reader. Bind any upload to the
+company, task, agent and originating run; verify bytes/hash and create normal
+attachment/work-product records. Do not fetch arbitrary model-supplied URLs.
+Binary transfer is a later capability gate, not a reason to delay the initial
+task/document provider.
+
+### Accounting
+
+Record provider usage and provider cost as unknown. Preserve separately measured
+costs of Paperclip-mediated paid tools. No guessed token counts or zero-cost run
+records. Display **Dot usage is managed outside Paperclip**.
+
+Continue normal budget checks before admission and every paid/mutating action.
+Budget exhaustion prevents new Paperclip work and fences the binding's current
+run. Since token spend and external execution are unobservable, Paperclip cannot
+promise a hard dollar cap on Dot's own activity. A policy requiring fully metered
+provider spend must make this provider ineligible. Otherwise require the
+operator's explicit selection of an externally billed/unmetered provider
+profile, plus concurrency, operation-count and authority-time limits.
+
+This distinction is a product contract, not permission to weaken existing
+company budget hard stops for costs Paperclip actually controls.
+
+## 10. Onboarding and ongoing UX
+
+1. Choose **Paperclip Runner → OpenAI Dot**.
+2. Show stable MCP endpoint and connection/pairing flow. Cloud deployments use
+   the stable broker once its agent-resource routing is implemented; self-hosted
+   deployments use authenticated public HTTPS.
+3. Connect the dedicated plugin, review the named company/agent delegation, and
+   copy/open the setup instruction in the user's existing Dot.
+4. Display separate setup stages: authenticated, tools callable, subscription
+   verified, test event received, test completed.
+5. Enable assignment only after the challenge completes. A slow tool refresh
+   shows **Waiting for Dot's tools** with retry guidance.
+6. Offer a real first task and display its result in the normal task surface.
+
+Keep normal environment diagnostics read-only. **Send test event** is a separate
+explicit action because it wakes an external model. Persist the setup test and
+its receipts so refreshing the page or retrying does not create multiple tests.
+
+Configuration shows binding owner, named agent, connection health, last successful
+test, last acceptance, subscription expiration and reconnect/disconnect actions.
+Do not show unused cwd, executable, model/effort or token-budget controls.
+
+Run UI distinguishes **Queued**, **Waiting for Dot**, **Accepted**, **Working**,
+**Waiting for input**, **Finalizing**, and **Needs reconnection/reconciliation**.
+These are projections over normal execution and bridge records, not a second
+issue-status system. Stop messaging describes the scope of what Paperclip can
+stop. Missing provider transcript detail is labelled as unavailable.
+
+The stable plugin description/instructions teach one standing subscription, inbox
+draining, exact identity/request-ID reuse, structured completion, current-context
+reads and no comment echo loops. Plugin directory listing is separate from
+private testing; workspace policy and public distribution review still apply.
+
+Any Apps catalog entry must follow `doc/connections/CONNECTOR-PLAYBOOK.md`.
+Do not model a user-entered Dot URL as a normal outbound MCP server connection:
+here, Dot is the MCP client.
+
+## 11. Implementation sequence and file map
+
+Deliver each slice behind a default-off Dot provider flag as well as the
+existing Runner/public-MCP requirements. Disabled means no new admission;
+preserve authorized cleanup/reconciliation of previously admitted work.
+
+### Slice 1 — Contracts and deterministic production topology
+
+**Change:** Define the Dot provider, binding snapshot, external-provider port,
+operation receipts, capability limitations and next native/PRP schema revisions.
+Add TypeScript/Rust parity fixtures and a scripted external peer.
+
+**Files:**
+
+- `packages/adapter-utils/src/paperclip-runner-permissions.ts`
+- `packages/paperclip-runner/protocol/schemas/` and protocol fixtures
+- `packages/paperclip-runner/src/contracts/{native-execution,harness-driver,types}.ts`
+- `packages/paperclip-runner/src/backends/native-backend-factory.ts`
+- Runner compatibility/export declarations and corresponding Rust protocol code
+
+**Exit:** A qualified test artifact recognizes Dot and rejects incompatible
+profiles/envelopes before dispatch; old-provider fixtures still pass. No
+production picker entry yet.
+
+### Slice 2 — Scoped connection, pairing and mailbox persistence
+
+**Change:** Dedicated agent OAuth resource/purpose, scoped binding, migrations,
+mailbox/operation records and event-source support. Retain personal MCP behavior.
+
+**Files:**
+
+- `packages/db/src/schema/public_mcp.ts`, new Dot schema module and exports
+- Generated migration via `pnpm db:generate`
+- `packages/shared/src/types/` and `validators/` for public configuration/status
+- `server/src/routes/public-mcp.ts`, agent-binding management routes
+- `server/src/services/public-mcp/{oauth,events,event-webhooks,dot-runner}.ts`
+- New `server/src/services/dot-runner/` binding, mailbox and operation services
+
+**Exit:** Restart-persistent pairing/subscriptions/receipts; cross-company,
+personal-to-agent escalation, callback verification and revocation tests pass.
+Operations can be stored safely before a controller is available.
+
+### Slice 3 — Rust provider and authenticated broker port
+
+**Change:** Implement the Dot executor, durable checkpoint, acceptance boundary,
+PRP external operation delivery and normal `ProviderToolBridge` integration.
+The app port implements only transport persistence/routing.
+
+**Files:**
+
+- New `runner/crates/runner-core/src/dot_provider_backend.rs` and state module
+- `runner/crates/runner-core/src/native_provider_backend.rs`
+- `runner/crates/runner-core/src/provider_bridge.rs` where shared extension is needed
+- Runner durable command/event validation and provider descriptor projection
+- `packages/paperclip-runner/src/drivers/dot/` reference/conformance implementation
+- Runnerd transport facade and `server/src/services/native-runtime/runner-prp-coordinator.ts`
+
+**Exit:** A real Rust runnerd and scripted MCP peer complete an assignment through
+the app-owned tool authority. Killing either process at a receipt boundary does
+not repeat a committed effect. The memory-only prototype is not used by this test.
+
+### Slice 4 — Normal task admission, tools and finalization
+
+**Change:** Select `openai_dot` from normal scheduling, acquire checkout and
+controller authority, construct the immutable input, publish admitted work and
+route results through existing completion feedback/status policy.
+
+**Files:**
+
+- `server/src/services/native-runtime/{provider-profile,runtime-mode,prepare-native-run,native-execution-input}.ts`
+- `server/src/services/native-runtime/native-session-executor.ts`
+- `server/src/services/native-runtime/paperclip-runner-tool-authority.ts`
+- `server/src/services/native-runtime/{native-run-coordinator-store,native-run-finalizer,status-arbiter}.ts`
+- Narrow integration points in `server/src/services/heartbeat.ts`
+
+**Exit:** Assign a real test issue to the Dot agent; it writes a normal document
+and proposes completion; the ordinary finalizer decides issue status. Reads,
+mutations, work modes, approvals and budget denials use existing authorities.
+
+### Slice 5 — Continuations, stop and recovery
+
+**Change:** Restore exact assignments across controller/runner restarts, deliver
+slow-operation results, implement question/approval response wakes, and fence
+cancelled/paused/reassigned work without claiming external shutdown.
+
+**Files:**
+
+- `server/src/services/native-runtime/{native-restart-recovery,native-session-resume,native-runner-ownership}.ts`
+- `server/src/services/{acknowledged-native-stop,remote-execution-termination,execution-recovery-attempt}.ts`
+- Existing interaction/continuation services and Dot mailbox reconciliation
+- Rust Dot recovery/checkpoint tests and protocol fixtures
+
+**Exit:** Fault matrix in section 8 passes, with no duplicate writes or stale
+callback authority. Unknown effects produce visible reconciliation, not an
+automatic retry storm. A long human wait survives process restarts.
+
+### Slice 6 — Product onboarding and read models
+
+**Change:** Provider configuration, pairing/challenge UI, normal diagnostics,
+connection health, run phase/stop semantics, and CLI watch output.
+
+**Files:**
+
+- `ui/src/adapters/paperclip-runner/index.ts` and its configuration components
+- Agent creation/configuration and assistant-connection views/API clients
+- Shared provider/connection status types and experimental-setting contracts
+- CLI Runner event formatting/config diagnostics
+- `integrations/assistant-plugins/` setup instructions/package as appropriate
+
+**Exit:** A user can connect an existing Dot and complete the first task without
+terminal commands, UUID transcription, database edits or browser automation.
+UI follows `DESIGN.md`/design skill, token gates and standard form footers.
+
+### Slice 7 — Hosted routing and deployment qualification
+
+**Change:** Stable public endpoints, agent-resource routing and grant purpose in
+the Cloud broker, membership/revocation checks, key persistence, readiness and
+sleep/wake behavior. Keep the account-to-tenant routing authority server-owned.
+
+**Ownership:** Instance-side changes in this repo; Cloud broker/deployment
+changes in the companion Cloud repository. Track that dependency explicitly.
+
+**Exit:** Hosted and directly reachable self-hosted tests separately pass.
+Private-network-only installs report the missing reachability prerequisite.
+No temporary tunnel URL is shipped as configuration.
+
+### Slice 8 — Real-account acceptance and release gate
+
+**Change:** Full-stack evaluation fixtures, real Dot acceptance evidence,
+operational docs and qualified provider catalog entry.
+
+**Exit:** Real user onboarding → real assigned issue → signed wakeup → accepted
+turn → normal tool effect/document → structured result → ordinary finalization,
+plus restart, duplicate-delivery, revoke and cancellation scenarios. Record exact
+artifact/contract revisions and distinguish simulator from real-account results.
+
+Critical path: 1 → 2 → 3 → 4 → 5 → 8. Slice 6 consumes the status contracts;
+slice 7 is required before advertising hosted support. A hidden vertical slice
+after 4 is useful for real testing, but qualification requires 5 and 8.
+
+## 12. Verification and release criteria
+
+### Deterministic checks
+
+- Shared TS/Rust fixtures: invalid version, wrong binding, stale generation,
+  changed request input, duplicate accept/finish and terminal ordering.
+- Persistent DB tests: atomic assignment/outbox, uniqueness under concurrent
+  acceptance, one active assignment, subscription gap repair, lease takeover,
+  retention limits and unsubscribe audit preservation.
+- Actual semantic authority tests: repeated task/document/comment effects,
+  approval gates, planning/ask restrictions, membership loss, budget stop,
+  grant revocation before/after dispatch and response replay.
+- Recovery tests: crash at every commit/ack boundary; preserve uncertain writes;
+  conflicting snapshots fail closed; no fresh request IDs on automatic retry.
+- Boundary tests: no personal privilege through the agent resource, forged Dot
+  URLs have no authority, no callback SSRF/redirects, stale catalog cannot call
+  removed tools, large input/output stays bounded, and no credentials in logs.
+- Control tests: accepted-but-silent Dot, stop/finish race, in-flight write after
+  cancellation, late result after reassignment, duplicate/batched/out-of-order
+  events and slow operation completion.
+- Context tests: current wake comments, assigned instructions/skills, question
+  answers and completion revisions survive continuation without leaking another
+  run's context or claiming native provider session resume.
+
+### Live qualification
+
+Use a disposable company with real scheduling and the built Rust artifact.
+Record dispatch-to-webhook, webhook-to-accept and accept-to-result durations as
+observations, not an OpenAI SLA. Repeat after a server restart and after OAuth
+refresh. Verify that a task assigned while disconnected resumes once after
+reconnection. Test two queued tasks and a human-question continuation.
+
+Prove subscription removal/revocation from server state, not just Dot's prose.
+Test pending external activity separately from Paperclip authority revocation.
+Record unknown usage honestly. Keep the endpoint up through the entire test.
+
+### Commands and evidence
+
+Start with targeted Runner contract/driver, MCP, DB and native-runtime tests.
+Use the repository's Runner and Product E2E eval skills when implementing their
+fixtures. Run Rust/TypeScript parity, build/package compatibility and standalone
+consumer checks for changed public Runner contracts.
+
+Before a PR-ready handoff, run:
+
+```sh
+pnpm -r typecheck
+pnpm test:run
+pnpm build
+pnpm check:token-gates # when UI changes are present
+pnpm --filter @paperclipai/paperclip-runner verify
+```
+
+Browser/product suites are opt-in and required for the onboarding/live acceptance
+slice, not for each small contract edit. Update the PR template in full and
+attach inspectable evidence to the implementation issue/work product.
+
+Keep operational counters in the run log or configured OpenTelemetry path.
+First-party Telemetry is a separate opt-out data path: any new Telemetry events
+require its generated contract, README update and privacy review. Do not add
+prompts, callback URLs, document bodies or credential material to any diagnostic.
+
+Release requires all of the following:
+
+1. Normal task admission and finalization through Rust runnerd.
+2. Dedicated agent delegation and current-authority enforcement.
+3. Durable transport/operation recovery without duplicated known effects.
+4. Accurate stop, usage, model and workspace limitations in UI and API.
+5. Real-account onboarding and multi-turn acceptance at a stable URL.
+6. No regressions in existing Runner providers or personal MCP connections.
+7. Rollback can disable new Dot work while retaining safe cleanup and receipts.
+
+## 13. Deliberate deferrals and open validation
+
+Defer provider-native steering, remote kill guarantees, model selection,
+multi-agent sharing of one connection, verified provider thread identity,
+token accounting, arbitrary repository access and binary file transfer until a
+documented capability and corresponding qualification exist.
+
+Before public availability, validate long-duration event subscriptions and
+refresh in the real Dot client; tool-catalog propagation after reconnect; large
+catalog/result behavior; and hosted app approval/distribution requirements for
+the selected release channel. The successful short lab test proves none of
+those by itself.
+
+The largest implementation risk is accidentally treating Dot as a controllable
+process. The design must continue to work when it is an independent remote
+assistant that can be delayed, retain unrelated context, or keep doing things
+outside Paperclip after its Paperclip authority ends.

+it is a repository plan rather than an uploaded issue artifact. When execution
+is assigned in Paperclip, link this plan as its plan document/work product.
