## Linked Issues or Issue Description
**What existing behavior does this improve?**
This improves the Apps connection setup flow, managed Google connection
flow, generic MCP connection flow, navigation, and runtime origin
discovery.
**Subsystem affected**
Cross-cutting. This changes `ui/`, `server/`, `packages/shared/`,
connector documentation, and browser tests.
**Current behavior**
Apps require an experimental switch. Setup pages repeat titles and
explanatory copy. Connection names require manual input. Google
credential sharing does not always offer both personal and organization
access. Generic MCP providers do not start with the same permission
choices. Managed OAuth needs a public URL setting even when the request
already has a safe HTTPS origin.
**Proposed behavior**
Apps are available by default. Setup asks only for required permissions
and sharing choices. Paperclip creates conflict-free connection names.
Google apps and generic MCP providers use the same human and agent
access model. Managed OAuth derives a validated same-origin HTTPS URL
when no explicit public URL is set.
**Reason and benefit**
A clean self-hosted install can connect a managed Google app without
hidden setup. Humans can share a service account with their
organization. The shorter flow reduces duplicated choices and setup
errors.
**Breaking changes**
The Apps experimental switch is removed. Existing connection APIs remain
compatible. New connections can receive a numeric suffix when a name
already exists.
No duplicate or related public issue was found.
## What Changed
- Removed the Apps experimental gate and the breadcrumb that leaves the
Apps section.
- Simplified all connection setup pages and moved optional provider
requirements into one small link.
- Added consistent human and agent access choices for Google apps,
Zapier, and generic MCP connections.
- Added organization sharing to Google Workspace credentials while
keeping personal access available.
- Generated connection names automatically and resolved name conflicts
with numeric suffixes.
- Derived a validated public HTTPS origin from the request for
config-free managed OAuth.
- Updated connector contracts, tests, browser coverage, and authoring
documentation.
## Verification
- `pnpm check:token-gates`
- `pnpm -r typecheck`
- `pnpm build`
- `pnpm exec vitest run server/src/__tests__/tool-access-service.test.ts
server/src/__tests__/generic-mcp-connection.test.ts` (273 passed)
- Targeted UI/service regression suite (308 passed)
- Six targeted Playwright connection journeys on a fresh onboarding
instance (6 passed)
- Fresh-install browser proof through Tailscale HTTPS: enrolled with
Paperclip Cloud, connected managed Google Drive, and completed a real
read operation.
- [Exact-head CI
run](https://github.com/paperclipai/paperclip/actions/runs/33669760711):
all 23 matrix jobs passed, including build, typecheck, server,
serialized, canary, and all browser shards.
- Greptile 5/5 on `0ae2a859f269984ee950d0af231a5b09a06f3dfd`, with no
unresolved review threads.
## Risks
Apps are now visible to all operators. The removed experimental flag no
longer hides unfinished app definitions. Managed Google availability
still depends on the Cloud profile rollout and active instance
enrollment. Automatic conflict handling changes only the display name of
a newly conflicting connection.
> I checked [`ROADMAP.md`](ROADMAP.md). MCP Tool Gateway and Apps are
shipped. Connected Apps is planned, and this change improves the
existing shipped connection flow.
## Model Used
OpenAI Codex, GPT-5, with reasoning, browser control, tool use, and code
execution.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The backend now turns agent requests into durable connection
intents.
> - Operators need a clear path to inspect, configure, and finish those
requests.
> - The experience must preserve identity, agent access, and interrupted
setup state.
> - This pull request adds the connection intent setup experience across
the app UI.
> - The benefit is one guided flow from agent request to governed
connection.
## Linked Issues or Issue Description
Refs #11965
This is stack 9 of 11. It depends on stack 8 and replaces another
reviewable part of #11965.
## What Changed
- Add connection intent cards and setup flow integration.
- Add browse, connection, app detail, and sidebar experience updates.
- Preserve exact draft identity and access choices across resume and
OAuth recovery.
- Add focused UI, architecture, policy, and end-to-end coverage.
- Keep transient retained-connection lookup failures retryable instead
of misclassifying them as missing targets.
- Align the dark-mode E2E contract with the intentionally hidden
Gateways and Profiles sidebar tabs.
## Verification
- `pnpm -r typecheck`
- Focused UI result: 372 tests passed across 20 files.
- AppsConnect regression suite: 80/80 passed, including failed
connection and application lookups during retained reconnect.
- `pnpm --filter @paperclipai/ui exec vitest run
src/components/AppsSidebar.test.tsx` (1 passed)
- `pnpm check:token-gates`
- `pnpm --filter @paperclipai/db check:migrations`
- `pnpm build`
## Risks
- An interrupted OAuth flow can leave a durable draft that needs resume.
- The UI resumes the exact draft and keeps its identity and agent access
settings.
- Retained reconnect retries refetch connections and applications
together to avoid mixing partial snapshots.
- Gateways and Profiles remain route-accessible but intentionally absent
from the sidebar until their existing ship gate is lifted.
- The change does not add a database migration.
> I checked `ROADMAP.md`. This stack continues the existing app
connection work from #11965 and does not duplicate another planned item.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - External tools need explicit identity and access boundaries.
> - Shared connection credentials cannot represent every user-scoped use
case.
> - Grants must stay company-scoped and support safe delegation.

## Linked Issues or Issue Description
Refs #11965
This is stack 3 of 11. It depends on stack 2 and replaces another
reviewable part of #11965.
## What Changed
- Add company and user connection grants.
- Add delegated identity and membership rules.
- Synchronize database, shared, server, and UI contracts.
- Register the grant-member replacement route in the OpenAPI surface in
the same layer that mounts it.
- Add migration 0231 with replay-safe guards and coverage.
## Verification
- `pnpm -r typecheck`
- `pnpm --filter @paperclipai/server exec vitest run

- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/openapi-routes.test.ts` (5 passed)
- `pnpm --filter @paperclipai/db check:migrations`
- `pnpm build`
## Risks
- Incorrect grant selection could expose the wrong credential scope.
- The service enforces company and subject boundaries before credential
use.
- Migration 0231 is generated, ordered after 0230, and safe to replay.

## Linked Issues or Issue Description
Refs #11965
This is stack 2 of 11. It depends on stack 1 and replaces another
reviewable part of #11965.
## What Changed
- Improve remote tool gateway connection behavior.
- Add clearer app setup, test, and recovery states.
- Add focused server and UI tests for the new paths.
- Keep the diff isolated from later identity and catalog work.
- Stabilize DNS-pinned remote HTTP protocol fixtures and the
managed-runtime public-origin fixture for this independently tested
layer.
## Verification
- `pnpm -r typecheck`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/tool-access-service.test.ts` (150 passed)
- `pnpm test:run`
- `pnpm check:token-gates`
- `pnpm build`
## Risks
- Gateway errors now surface through new user-facing states.
- A stale connection can require a new setup attempt.
- The change does not add a database migration.
- The injected HTTP transport and public URL are test-only fixtures;
production DNS pinning and runtime behavior are unchanged.

## Linked Issues or Issue Description
Refs #11965
This is stack 1 of 11. It replaces the first reviewable part of #11965.
## What Changed
- Add guarded remote MCP setup and credential handling.
- Add PostHog OAuth and API key connection methods.
- Add focused server, shared contract, and UI coverage.
- Keep the migration replay-safe and idempotent.
- Give the late-close security regression the same 10-second CI headroom
as the adjacent real-timer handshake test.
- Synchronize fake-timer handshake tests at the exact ensure-session
boundary so real filesystem setup cannot race the fake deadline.
- Drive PTY overflow coverage only after listener registration so
scheduling cannot reorder the test fixture.
## Verification
- pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts
server/src/__tests__/plugin-worker-manager.test.ts (220 passed; affected
cases also passed five focused stress repetitions)
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts -t "never leaks a
sandbox-provided value from a late close rejection into logs or the
result"` (1 passed)
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts -t "never
promotes a late ensureSession resolution|closes a late-resolving real
handle exactly once"` (2 passed)
- `pnpm -r typecheck`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/tool-access-service.test.ts`
- `pnpm --filter @paperclipai/db check:migrations`
- `pnpm build`
## Risks
- Remote endpoint validation can reject configurations that previously
passed without checks.
- OAuth configuration errors can block setup until the operator corrects
the provider settings.
- The migration uses guarded statements so repeated execution is safe.
- The test-only synchronization changes do not affect runtime behavior;
they remove filesystem/fake-clock and listener-registration races
observed under parallel CI load.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.

> - The managed worktree runtime starts agent work in repository
worktrees.
> - The Apps routes do not match the main discovery flow, and the

> - This pull request makes app discovery the main Apps route and makes

> - The benefit is a clearer Apps workflow and a safer managed-worktree
startup path.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
This improves the Apps navigation, app connection management, managed
git-worktree startup, and CLI worktree selection.
**Subsystem affected**
Cross-cutting. The change affects `ui/`, `server/`, `cli/`, and
development documentation.
**Current behavior**
The `/apps` route opens the connections list while discovery uses a
nested route. The connections list has no delete action. Some legacy
managed worktrees can start runtime work before their pending seed
operation runs. The CLI can also read an ambient Paperclip config
instead of the repository-local config.
**Proposed behavior**
The `/apps` route opens Browse, and `/apps/connections` opens the
connection list. Users can delete a connection after confirmation.
Runtime startup seeds legacy managed worktrees when required. The CLI
resolves the current worktree from the repository-local
`.paperclip/config.json` file.
**Reason and benefit**
Users can discover apps from the canonical Apps route and can manage
existing connections from a dedicated route. Legacy worktrees receive
their required repository content before agent runtime starts. CLI
worktree selection stays scoped to the current repository.
**Breaking changes**
The `/apps` and `/apps/browse` route behavior changes. Old Browse links
redirect to `/apps`. The change does not modify an API schema or
database schema.
## What Changed
- Make Browse the canonical `/apps` page and move the connection list to
`/apps/connections`.
- Align Apps navigation, redirects, attention links, empty states, and
connection actions with the new routes.
- Add connection deletion with confirmation and clear failure feedback.
- Seed legacy managed git worktrees before runtime startup when their
seed status is pending.
- Read the CLI worktree selection from the repository-local Paperclip
config.
- Update focused UI, server, CLI, and development documentation
coverage.
## Verification
- Ran 202 focused UI, server, and CLI tests. All tests passed.
- Ran `pnpm -r typecheck`. All projects passed.
- Ran `pnpm build`. All projects built successfully.
- Ran `pnpm test:run`. The server and UI stages passed 7,168 tests. The
CLI stage found one environment-sensitive secrets test because this
workspace injects static AWS credentials. The isolated CLI file passed
all 8 tests after those injected variables were unset.
- Ran `pnpm check:token-gates`. It reports 12 existing color-token
violations in the unchanged `PaperclipOrbit3D.tsx` file from the target
branch. This pull request does not modify that file.
- Ran focused regression coverage for repository-root CLI config
resolution and connection deletion state. All tests and affected package
typechecks passed.
- Collected all 27 tests in the six changed Playwright specifications
successfully.
- GitHub Actions passed every latest-head CI gate, including all three
e2e shards and the aggregate `e2e` and `verify` jobs.
- Greptile reviewed the final commit at 5/5 with zero unresolved
threads.
## Risks
- Existing bookmarks for `/apps/browse` redirect to `/apps`.
- Connection deletion changes visible connection state and requires user
confirmation.
- The legacy seed path runs only for managed git worktrees with pending
seed state. Tests cover the startup condition.
- The rebase preserves the target branch's direct OAuth policy for the
Notion connection flow.

## Model Used
OpenAI Codex with the GPT-5 model family assisted this change. The agent
used reasoning, repository tools, code execution, and test execution.

## 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.
