DottaandPaperclip 3db2e6bdd2 feat(mcp) [split 8/8]: add e2e coverage and operator docs (#9563)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Governed MCP access spans contracts, runtime enforcement, adapters,
UI surfaces, and operator verification
> - The parity reference PR #9534 is too large for effective automated
or human review
> - The feature therefore needs a linear stack whose individual diffs
stay below the 100-file review limit
> - This pull request is split 8/8 and focuses on end-to-end coverage,
operator docs, evals, and release notes
> - The benefit is a standalone, testable review boundary while
preserving byte-for-byte parity at the top of the stack

## Linked Issues or Issue Description

- Related parity reference: #9534
- Problem: The complete stack needs discoverable browser scenarios,
operator guidance, threat modeling, eval coverage, and a parity proof
before merge.
- Proposed solution: Adds MCP user-story and Smoke Lab e2e suites,
docs/evals/release notes, the skill update, and the root e2e driver
script registration.
- Alternatives considered: keeping #9534 as one 403-file review, or
rewriting the feature to manufacture seams; both were rejected in favor
of path extraction plus compile-driven boundary moves.
- Roadmap alignment: this advances the existing governed MCP/tool-access
work already represented by #9534; it does not introduce a separate
roadmap initiative.
- Stack position: base branch is `pap10341-split/07-ui-apps-activation`.
- Merge policy: merge bottom-up, in order, only after the complete
eight-PR stack has been reviewed and the top-of-stack parity gate
remains empty.
- Requested review: QA for flag audit and e2e/browser acceptance;
Greptile on every PR.

## What Changed

- Adds MCP user-story and Smoke Lab e2e suites, docs/evals/release
notes, the skill update, and the root e2e driver script registration.
- Keeps this PR below 100 changed files and independently typecheckable.
- Preserves the final tree from #9534 when combined with the other seven
stack levels.

## Verification

- `pnpm typecheck`
- `node --check scripts/e2e-mcp-user-stories.mjs`
- `pnpm exec playwright test --config tests/e2e/playwright.config.ts
--list` — 43 tests discovered
- `git diff pap10341-split/08-e2e-docs
6b40e3876d9297105d4ec306e47e46d351c86172` — empty (0 bytes)

## Risks

- Browser suites depend on runtime services and environment setup; this
PR validates discovery locally while QA owns full flag-on/flag-off
execution.
- Stack risk: merging out of order can expose incomplete layers;
mitigate by following the documented bottom-up merge policy.
- Parity risk: later edits to an intermediate branch can drift from
#9534; mitigate by re-running the empty top-of-stack diff before merge.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI Codex, exact model ID `gpt-5.4`; runtime-managed context
window; medium reasoning with repository, shell, Git, GitHub CLI, and
code-execution tools enabled.

## Stack Coordination

- Internal execution plan:
[PAP-13874](/PAP/issues/PAP-13874#document-plan)
- Parity reference: #9534
- Stack: #9556 → #9557 → #9558 → #9559 → #9560 → #9561 → #9562 → #9563
- Merge bottom-up only after full-stack review and an empty parity diff
at #9563.

# Apps, Connections, and Integrations
Audience: internal engineers and product contributors working on integrations.
Post-read action: classify a new integration request, pick the right Paperclip
layer to change, and avoid creating a parallel connection framework.
## Decision Record
Board decisions from [PAP-13211](/PAP/issues/PAP-13211) make the Apps v2
substrate on the PAP-10341 branch canonical:
- **D1: Apps v2 is the substrate.** The active model is
`tool_applications`, `tool_connections`, catalog entries, profiles, policy
rules, action requests, gateway sessions, audit events, and runtime slots.
Connections v1 is retired as an implementation path.
- **D2: one vault, brokered projections.** Durable third-party credentials live
in `company_secrets` as secret refs. Adapter config, plugin config, harness
credential files, and run environments may receive only brokered or projected
credentials.
- **D3: the vocabulary and three-door IA are product law.** The default product
doors are Apps, Connections, and Review. Protocol and operator-depth concepts
live behind Developer or Advanced surfaces.
- **D4: unification lands on PAP-10341.** Pages, CircleBack-style harness MCP
OAuth, provider gallery work, and plugin-provided integrations converge on
this branch instead of spawning new integration substrates.
- **D5: inbound stays thin.** External clients that call Paperclip use scoped
Paperclip tokens and existing profiles/rules. They do not get a separate
permission model.
## Canonical Object Model
Use **connection** as the unifying noun. A connection is four things:
1. A stored credential reference.
2. A capability catalog.
3. A governance layer.
4. An audit trail.
Everything else is an axis on that object:
| Axis | Values | It answers |
| --- | --- | --- |
| Direction | outbound, inbound | Who is the client? |
| Transport | MCP, native REST/OpenAPI, OAuth app install, webhook | How do bytes move? |
| Auth mode | OAuth, API key/PAT, app installation, none | What does the secret represent? |
| Credential owner | company, user, run | Whose identity acts? |
| Packaging | catalog entry, plugin, skill | How does it ship? |
MCP is a transport, not a product category. "Install the Discord app",
"connect Google Drive", and "add an MCP endpoint" all produce governed
connections with different transport/auth values.
## Layer Stack
When you are unsure where a change belongs, place it on the narrowest layer that
solves the problem:
| Layer | Owns | Examples |
| --- | --- | --- |
| Surface | user-facing Apps, Connections, Review, Developer/Advanced screens | gallery cards, setup wizard, review queue |
| Governance | profiles, bindings, allow/ask-first/block rules, quarantine, audit | read-only profile, ask-first write policy |
| Capability | action catalogs, schemas, risk classes, changed-tool review | `search_issues`, `create_comment`, schema hash |
| Credential | `company_secrets`, OAuth broker, credential resolver, token broker | Slack bot token ref, Google OAuth refresh token ref |
| Identity | actor attribution and token exchange | board user, agent run, first-party service identity |
| Transport | how the external system is reached | remote HTTP MCP, local stdio, REST/OpenAPI, webhook |
The agent should not hold a durable provider credential. It should hold a
Paperclip run/session token; the server or broker resolves the connection,
checks governance, invokes the provider, and writes audit.
## Packaging Rule
Default to a **catalog entry** when an integration can be described as metadata:
manifest, auth config, action catalog, resource filters, and policy defaults.
Use a **plugin** only when the integration needs product code such as custom UI
pages, its own tables, workers, migrations, routines, or specialized ingestion.
A plugin may bundle catalog entries, but it must not bypass the connection,
profile, policy, credential, and audit model.
Use a **skill** for agent instructions. Skills may use connections; they must
not own durable tokens.
## Canonical Docs
- [Glossary](./GLOSSARY.md) defines product and internal terms.
- [Security threat model](./SECURITY-THREAT-MODEL.md) harvests the keeper from
[PAP-2359](/PAP/issues/PAP-2359) and maps it onto Apps v2.
- [First-30 matrix](./FIRST-30-MATRIX.md) harvests the keeper from
[PAP-2432](/PAP/issues/PAP-2432) and is the source matrix for connector
playbook work.
- [Connector playbook](./CONNECTOR-PLAYBOOK.md) is the repeatable template for
adding a vendor as a catalog entry on Apps v2.
- [MCP access governance](../MCP-ACCESS-GOVERNANCE.md) remains the operator
runbook for the current gateway, profile, policy, approval, runtime, and audit
APIs.
## Migration Notes
Connections v1 contributed useful policy, UX, and rollout thinking, but its
implementation branch is no longer the target. When you see old tickets or code
using `connections`, `connection_grants`, or a provider-directory mental model,
translate the intent into Apps v2:
| Connections v1 intent | Apps v2 home |
| --- | --- |
| Provider directory | Apps gallery / `tool_applications` |
| Configured provider instance | Connection / `tool_connections` |
| Grant allowlist | Profiles, profile bindings, policies |
| Resource filters | Policy/profile conditions plus provider config |
| Tool broker | Tool gateway and runtime supervisor |
| Connection UX tail | Apps, Connections, Review, Developer/Advanced IA |
Do not add new work to the retired v1 branch. If an old ticket still describes a
valid product gap, retarget it to an active Apps v2 issue or close it as
superseded with a link to the replacement.
