## Thinking Path
> - Paperclip is the open source control plane people use to manage
AI-agent companies.
> - Operators need a board-level way to monitor a changing slice of
company work without repeatedly rebuilding filters or reading raw task
threads.
> - Existing summaries are useful snapshots, but they do not provide a
dedicated query-backed card with refresh policy, change tracking, update
history, and per-update cost visibility.
> - The capability needs to be safe to evaluate before it becomes part
of the default product surface.
> - This pull request adds end-to-end experimental Status Cards, from
schema and query compilation through update orchestration and operator
UI.
> - The entire feature is gated behind the `enableStatusCards`
experimental toggle, including its route and sidebar entry.
> - The benefit is a governed, inspectable way to keep focused
operational rollups current while preserving explicit controls over
refresh frequency and spend.
## Linked Issues or Issue Description
### Subsystem affected
Cross-cutting (`packages/db`, `packages/shared`, `server/`, `ui/`, and
bundled skills/docs).
### Problem or motivation
Operators cannot currently define a reusable natural-language view of
company work, compile it into an inspectable query, and keep its summary
current as matching issues change. Rebuilding filters and rereading task
threads makes board-level monitoring repetitive and hides the
relationship between source changes, refresh cost, and the resulting
summary.
### Proposed solution
Add experimental Status Cards that compile operator intent into a query,
summarize matched work, record each update, expose
manual/interval/reactive refresh policies and costs, and preserve the
last good result across stale, updating, paused, and error states. The
capability is off by default and fully gated behind `enableStatusCards`,
including its route and navigation entry.
### Alternatives considered
- Extend existing one-off summaries: rejected because status cards
require persistent query provenance, refresh policy, update history, and
card-specific cost controls.
- Add a dashboard-only filter widget: rejected because it would not
provide governed background refresh, an update ledger, or an inspectable
compile pipeline.
- Ship the surface by default: rejected in favor of an experimental
toggle while behavior and operator value are evaluated.
### Roadmap alignment
This advances Paperclip’s board-level execution visibility and
output-first product goals. `ROADMAP.md` was checked and no duplicate
status-card initiative was found.
### Additional context
No related open PR was found in the public GitHub search for status
cards. The PR-only design wireframes were removed from the repository
after review; the published prototype remains external to the production
source tree.
## What Changed
- Added company-scoped status-card schema, CRUD APIs, compile
provenance, update ledger, shared contracts, validators, and OpenAPI
coverage.
- Added the text-to-query compile pipeline, bundled `status-card-query`
agent skill, query versioning, and authorized write-back flow.
- Added the experimental board, create flow, lifecycle tiles,
detail/settings/debug drawers, archived view, routing, navigation, and
instance setting.
- Added a change-gated update engine with manual, interval, and reactive
refresh policies, trigger selection, active hours, and daily token caps.
- Added per-update token/cost recording, today and lifetime rollups, and
policy-derived cost previews.
- Added operator documentation and agent-authoring hardening for compile
and update behavior.
- Added PR-prep integration coverage for settings/startup wiring and
replaced raw UI values with design-system tokens.
- Removed the PR-only `design/pap-15023-status-cards` wireframe
artifacts so the repository contains only production feature assets.
## Verification
- `pnpm -r typecheck` — passes on the PR head; includes `ui` `tsc -b`
passing. The UI compile gate was also independently recorded as passing
at `6d7f3cf96b` on July 23, 2026.
- `pnpm build` — passes.
- `pnpm check:token-gates` — passes with all three gates clean.
- `pnpm test:run` — 2,880 tests passed and 1 skipped; the sole failure
was an unrelated 10-second `afterAll` database-cleanup timeout in
`execution-workspaces-service.test.ts`.
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/execution-workspaces-service.test.ts` — passes on
immediate focused rerun (25/25).
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/instance-settings-service.test.ts
src/__tests__/server-startup-feedback-export.test.ts` — passes (31/31).
- `pnpm --filter @paperclipai/ui exec vitest run
src/pages/StatusCards/StatusCardSettingsForm.test.tsx
src/pages/StatusCards/StatusCardTile.test.tsx
src/pages/StatusCards/format.test.ts src/lib/status-card-state.test.ts`
— passes (26/26).
- Recorded pre-PR QA: compile-pipeline e2e PASS; full lifecycle and cost
QA PASS; security re-review PASS after write-back hardening; UX
approved.
- `pnpm exec vitest run packages/db/src/status-card-migrations.test.ts`
— passes; reapplies migrations `0185`–`0189` against an already-migrated
embedded Postgres database.
- `pnpm --filter /db check:migrations` — passes migration numbering and
safety checks.
- `pnpm --filter /db typecheck` — passes.
- Merged current `origin/master` on July 24, 2026 with no conflicts;
migrations `0185`–`0189` remain unclaimed on master.
## Risks
- The feature introduces five database migrations and a new background
update path; all new DDL is repeat-safe after partial application,
migration numbering/safety checks pass, and update execution is
company-scoped and change-gated.
- Natural-language compilation can produce invalid or overly broad
queries; compile provenance, query validation, debug visibility, and
version history make failures inspectable and recoverable.
- Reactive or interval refresh could increase spend; active hours, max
refresh frequency, daily token caps, per-update cost records, and
budget-paused states bound and expose that risk.
- The branch name contains an internal execution identifier because it
is a fixed handoff branch; it was intentionally not renamed or rebased
per the release handoff instructions.
- Overall rollout risk is limited because the route, navigation,
services, and UI are disabled by default behind `enableStatusCards`.

## Thinking Path
> - Paperclip is the control plane operators use to manage AI-agent
companies.
> - Board operators rely on the settings UI and CLI docs to understand
which product surfaces are stable to depend on.
> - Experimental features already existed in the product, but the
operator-facing contract around them was too soft and too fragmented.
> - That created a risk that users would enable experiments without
being told clearly that they can break, change, or disappear.
> - The docs and the in-product settings page both needed the same
explicit warning language so the contract is visible at the moment of
decision.
> - This pull request adds that warning to the board-operator guide, CLI
references, and the experimental settings page.
> - The benefit is clearer operator expectations without changing the
underlying feature flags or rollout behavior.
## Linked Issues or Issue Description
No public GitHub issue exists for this docs/polish gap.
Problem description:
- Board operators could enable experimental features without a clear
operator-facing statement that those features are opt-in and come
without compatibility guarantees.
- The docs site, repo CLI reference, and in-product experimental
settings page did not present one consistent warning contract.
- This PR closes that gap by documenting the risk explicitly where
operators discover and enable those settings.
Related public search:
- Searched public issues/PRs for related work with `gh search issues
--repo paperclipai/paperclip 'experimental features warning'` and `gh
search prs --repo paperclipai/paperclip 'experimental features
warning'`.
- Reviewed open PR #6165 during that search and found it unrelated; it
changes experimental auth/routing flags rather than documenting
experimental-feature risk.
## What Changed
- Added a new board-operator guide at
`docs/guides/board-operator/experimental-features.md` that defines the
Paperclip contract for experimental features.
- Registered that guide in `docs/docs.json` so it appears in the public
docs navigation.
- Added matching caveat language next to `instance
settings:experimental` in `docs/cli/control-plane-commands.md`.
- Added the same caveat to `doc/CLI.md` so the repo CLI reference does
not drift from the published docs.
- Added a single page-level warning banner to
`ui/src/pages/InstanceExperimentalSettings.tsx` stating that
experimental features are opt-in, carry no compatibility guarantees, and
may change, break, or be removed.
- Added a targeted UI test in
`ui/src/pages/InstanceExperimentalSettings.test.tsx` that asserts
exactly one page-level warning renders with the new risk language.
## Verification
- `jq empty docs/docs.json`
- `git diff --check`
- `cd ui && pnpm vitest run
src/pages/InstanceExperimentalSettings.test.tsx`
- Manual review of the warning contract across:
- `docs/guides/board-operator/experimental-features.md`
- `docs/cli/control-plane-commands.md`
- `doc/CLI.md`
- `ui/src/pages/InstanceExperimentalSettings.tsx`
UI note:
- This is a copy-level warning addition rather than a layout rework. I
did not attach before/after screenshots in this PR body.
## Risks
- Low risk: this changes operator-facing documentation and warning copy,
not feature-flag behavior.
- The main failure mode is wording drift across docs and UI in future
edits, which is why this PR adds the same contract to all relevant
operator-facing surfaces.
> I checked `ROADMAP.md` before opening this PR. This is docs/UI polish
around an existing experimental surface, not overlapping roadmap-level
core feature work.
## Model Used
- OpenAI Codex Local using `gpt-5.4` with high reasoning and tool use
for coordination, review, docs changes, and PR preparation.
- Anthropic Claude Local using `claude-opus-4-8` with high reasoning and
tool use for the in-product warning and targeted UI test.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The task lifecycle and recovery subsystems decide when agent work is
still productive, stalled, or ready for review.
> - Existing recovery paths can observe stopped or incomplete work, but
there was no first-class per-task watchdog model with scoped review
permissions.
> - Watchdog follow-ups also need strict boundaries so
recovery/status-only runs cannot mutate approvals or perform deliverable
work.
> - This pull request adds the task watchdog data model, API/service
layer, scheduler/review flow, adapter wake context, UI configuration
surfaces, and docs.
> - The branch has been rebased onto current `paperclipai/paperclip`
`master`; the watchdog migration is now ordered after master's latest
migrations as `0104_issue_watchdogs`.
> - The benefit is a more explicit task-review loop that preserves
Paperclip's single-assignee and governance invariants while making
stalled work easier to route.
## Linked Issues or Issue Description
No linked GitHub issue. Paperclip task:
[PAP-11275](/PAP/issues/PAP-11275).
## Problem or motivation
Task recovery needs a first-class watchdog path that can inspect stopped
work and create scoped follow-ups without bypassing normal task
ownership. Board/UI users need a way to configure watchdogs on tasks and
see watchdog-related live work. Recovery/status-only runs must remain
limited to status reporting and must not create approvals, link
approvals, or submit approval comments.
## Proposed solution
Add a task-watchdog data model, scheduler/classifier, scoped mutation
guard, adapter wake context, API/UI configuration surfaces, and
documentation so watchdog agents can review stopped task subtrees under
explicit boundaries.
## Alternatives considered
Reuse the existing recovery-action flow only. That would keep
stopped-work detection implicit, make per-task watchdog assignment
harder to expose in the UI, and would not provide a durable
scoped-review issue for stalled task trees.
## Roadmap alignment
This is Paperclip control-plane lifecycle infrastructure for task
execution and recovery. I checked `ROADMAP.md`; this PR does not
duplicate an existing planned core item.
## What Changed
- Added issue watchdog schema, migration, shared contracts, validators,
CRUD API, and service support.
- Added task watchdog scheduler/classifier behavior, scoped mutation
enforcement, adapter wake context, and default watchdog mandate
guidance.
- Added UI surfaces for configuring watchdogs on new/existing tasks,
viewing watchdog activity, and exposing the experimental setting.
- Added docs for the user-facing task watchdog workflow and
implementation semantics.
- Gated new-task watchdog setup behind `enableTaskWatchdogs` and blocked
cheap status-only recovery runs from approval mutations.
- Rebased onto current `master` and renumbered the idempotent watchdog
migration from the branch-local `0102_issue_watchdogs` slot to
`0104_issue_watchdogs`.
- Addressed Greptile feedback by loading watchdog classifier input with
a recursive subtree query and centralizing the watchdog origin-kind
constant.
- Added and updated focused server/UI tests for watchdog routes,
scheduler/classifier behavior, scope boundaries, live task visibility,
settings, and new issue dialog behavior.
## Verification
- `pnpm vitest run server/src/__tests__/task-watchdogs-scheduler.test.ts
server/src/__tests__/task-watchdogs-classifier.test.ts`
- `pnpm vitest run
server/src/__tests__/approval-routes-idempotency.test.ts
server/src/__tests__/issue-agent-mutation-ownership-routes.test.ts`
- `pnpm vitest run ui/src/components/NewIssueDialog.test.tsx`
- `pnpm --filter @paperclipai/server typecheck`
- `git diff --check`
- Verified the PR diff does not include `pnpm-lock.yaml` or
`.github/workflows`.
## Risks
- Medium risk: this introduces a new task lifecycle surface touching DB
schema, server routes/services, adapter wake context, and UI task
configuration.
- Watchdog scheduling behavior depends on the new experimental setting
and runtime context checks behaving consistently across local and
production agents.
- The watchdog migration is idempotent (`IF NOT EXISTS` /
duplicate-object guards) so users who tried the previous branch-local
migration number should not get duplicate-object failures.
- CI and the second Greptile pass are pending after the latest
review-fix push.

## Model Used
OpenAI Codex, GPT-5-class coding agent in the Paperclip workspace. Exact
runtime model id and context window were not exposed to the agent; tool

## Thinking Path
> - Paperclip is the control plane for autonomous AI companies.
> - V1 needs to stay local-first while also supporting shared,
authenticated deployments.
> - Human operators need real identities, company membership, invite
flows, profile surfaces, and company-scoped access controls.
> - Agents and operators also need the existing issue, inbox, workspace,
approval, and plugin flows to keep working under those authenticated
boundaries.
> - This branch accumulated the multi-user implementation, follow-up QA
fixes, workspace/runtime refinements, invite UX improvements,
release-branch conflict resolution, and review hardening.
> - This pull request consolidates that branch onto the current `master`
branch as a single reviewable PR.
> - The benefit is a complete multi-user implementation path with tests
and docs carried forward without dropping existing branch work.
## What Changed
- Added authenticated human-user access surfaces: auth/session routes,
company user directory, profile settings, company access/member
management, join requests, and invite management.
- Added invite creation, invite landing, onboarding, logo/branding,
invite grants, deduped join requests, and authenticated multi-user E2E
coverage.
- Tightened company-scoped and instance-admin authorization across
board, plugin, adapter, access, issue, and workspace routes.
- Added profile-image URL validation hardening, avatar preservation on
name-only profile updates, and join-request uniqueness migration cleanup
for pending human requests.
- Added an atomic member role/status/grants update path so Company
Access saves no longer leave partially updated permissions.
- Improved issue chat, inbox, assignee identity rendering,
sidebar/account/company navigation, workspace routing, and execution
workspace reuse behavior for multi-user operation.
- Added and updated server/UI tests covering auth, invites, membership,
issue workspace inheritance, plugin authz, inbox/chat behavior, and
multi-user flows.
- Merged current `public-gh/master` into this branch, resolved all
conflicts, and verified no `pnpm-lock.yaml` change is included in this
PR diff.

- Confirmed branch has no uncommitted changes and is `0` commits behind
`public-gh/master` before PR creation.
- Confirmed no `pnpm-lock.yaml` change is staged or present in the PR
diff.
## Risks
- High review surface area: this PR contains the accumulated multi-user
branch plus follow-up fixes, so reviewers should focus especially on
company-boundary enforcement and authenticated-vs-local deployment
behavior.
- UI behavior changed across invites, inbox, issue chat, access
settings, and sidebar navigation; no browser screenshots are included in
this branch-consolidation PR.
- Plugin install, upgrade, and lifecycle/config mutations now require
instance-admin access, which is intentional but may change expectations
for non-admin board users.
- A join-request dedupe migration rejects duplicate pending human
requests before creating unique indexes; deployments with unusual
historical duplicates should review the migration behavior.
- Company member role/status/grant saves now use a new combined
endpoint; older separate endpoints remain for compatibility.
- Full production build was not run locally in this heartbeat; CI should
cover the full matrix.
## Model Used
- OpenAI Codex coding agent, GPT-5-based model, CLI/tool-use
environment. Exact deployed model identifier and context window were not
exposed by the runtime.
