Dotta dbebf30c89 Add low-trust review containment (#7530)
## Thinking Path

> - Paperclip is a control plane for AI-agent companies, so execution
policy and trust boundaries are part of the product's safety contract.
> - Low-trust review work needs narrower authority than normal
same-company agents because hostile PRs, comments, attachments, and
generated output can carry prompt-injection payloads.
> - The current V1 shape gives trusted workers broad company context,
which is useful for normal execution but too permissive for a reviewer
assigned to hostile content.
> - This branch adds a `low_trust_review` preset, source-trust tagging,
route-level containment, and quarantine handling so low-trust output
does not automatically flow into higher-trust wake context.
> - The branch has been rebased onto current `origin/master`, and the
low-trust migration was renumbered to `0097_low_trust_source_trust.sql`
to avoid collisions with existing `0091` through `0096` migrations.
> - Greptile feedback was addressed by tightening low-trust detection,
preserving project-level trust policy checks, fixing issue-kind
promotion lookup, removing duplicate post-lease isolation assertion,
documenting fail-closed source-trust behavior, bounding ancestry checks,
enforcing runtime issue context for CEOs, awaiting accepted-plan monitor
authorization, and making low-trust issue source-trust tagging atomic.
> - The benefit is a first production slice of deny-by-default review
containment with regression coverage for the main control-plane pivot
surfaces.

Fixes #7531.

## What Changed

- Added shared trust-policy types and validators, plus
database/source-trust fields for issues, comments, documents, and work
products.
- Implemented server enforcement for low-trust issue scope, agent
self-view redaction, secret/plugin/runtime denial paths, promotion
checks, and quarantined continuation/wake context.
- Added focused low-trust regression tests for resolver behavior, source
trust, route authorization, heartbeat preflight ordering, runtime
containment, and quarantine redaction.
- Added board UI affordances for selecting/reviewing the low-trust
preset and surfacing source-trust badges in relevant issue views.
- Added `doc/LOW-TRUST-PRESETS.md`, updated
`doc/SPEC-implementation.md`, and committed the low-trust review
contract plan under `doc/plans/`.
- Rebasing note: the original `0097_low_trust_source_trust.sql`
migration was renamed to `0097_low_trust_source_trust.sql`; the SQL uses
`ADD COLUMN IF NOT EXISTS` so users who already applied the old-numbered
migration are not broken by the renumbered migration.

## Verification

- Rebased branch onto current `origin/master` and force-pushed with
lease to `origin/PAP-10211-low-trust-agent` at head `2719f31e3`.
- Confirmed the PR diff does not include `pnpm-lock.yaml` or
`.github/workflows` changes.
- Resolved upstream UI/comment conflicts by preserving deleted-comment
tombstone behavior and low-trust source-trust badges/metadata.
- Renumbered the low-trust source-trust migration to
`0097_low_trust_source_trust.sql`; the SQL uses `ADD COLUMN IF NOT
EXISTS` so users who already applied an old-numbered copy are not
broken.
- `pnpm exec vitest run ui/src/lib/issue-chat-messages.test.ts
server/src/__tests__/heartbeat-workspace-session.test.ts`
- `pnpm exec vitest run server/src/__tests__/source-trust.test.ts
server/src/__tests__/workspace-runtime-service-authz.test.ts
ui/src/lib/trust-policy-ui.test.ts
ui/src/components/TrustPresetSection.test.tsx`
- `pnpm run typecheck:build-gaps`
- `git diff --check`
- GitHub checks pass on head `2719f31e3`: build, typecheck/release
registry, general tests, serialized server suites, e2e, canary, verify,
policy/review, Socket, and Snyk.
- Greptile Review passes with Confidence Score 5/5 and zero unresolved
Greptile review threads.
- No design screenshots/images were added because the task explicitly
says not to add them unless they are specifically part of the work.

## Risks

- Medium risk: this touches shared trust-policy contracts, server
authorization paths, heartbeat context generation, migration metadata,
and UI preset controls.
- Low-trust containment is intentionally deny-by-default; legitimate
future review workflows may need explicit allowlisted exceptions.
- Plugin/runtime/security surfaces are broad, so regression tests cover
the current known routes but future integrations must route through the
same containment layer.
- The PR is ready for review; GitHub checks are green and Greptile is
5/5.

> 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, GPT-5 coding agent, tool-enabled shell and GitHub CLI
workflow.

## Checklist

- [x] I have included a thinking path that traces from project context
to this change
- [x] I have specified the model used (with version and capability
details)

planned core work
- [x] I have run tests locally and they pass

- [x] UI changes are covered by focused tests; no screenshots were added
per task instruction not to add design images unless specifically
required

# Low-Trust Presets
Paperclip ships core trust preset names so containment decisions are enforced in
Community Edition even when EE policy editing is unavailable.
## Presets
- `standard`: the default V1 company-visible collaboration model. This preserves
existing behavior for normal agents.
- `low_trust_review`: an opt-in containment preset for automated work that may
consume hostile or prompt-injected input, such as untrusted pull requests,
external tickets, dependency diffs, or generated review output.
## Boundary Model
`low_trust_review` is resolved from existing JSON policy fields:
- agent permissions: `permissions.trustPreset` and
`permissions.authorizationPolicy.trustBoundary`
- project policy:
`executionWorkspacePolicy.authorizationPolicy.trustBoundary`
- issue/run policy: `executionPolicy.authorizationPolicy.trustBoundary`
The resolver intersects those sources. Narrower wins. A low-trust preset must
resolve to a concrete company-local project, root issue, or issue-id scope. If a
policy source names another company, uses an unsupported preset, or lacks that
scope for risky access, Paperclip fails closed.
## Containment, Not Privacy
This is containment for hostile automated work. It is not a general project,
issue, or human privacy system.
V1 standard work remains company-visible by default: board users and in-company
actors can inspect company work objects unless a separate access-control feature
changes that behavior. Low-trust containment instead limits what the low-trust
agent can read or mutate through the Paperclip API and prevents raw untrusted
output from being automatically promoted into higher-trust agent context.
## Runtime Containment
Managed `low_trust_review` runs fail closed unless Paperclip can enforce the
runtime boundary:
- the selected execution environment must use the `sandbox` driver
- the effective execution workspace mode must be `isolated_workspace`
- the issue being run must be inside the resolved low-trust boundary
- secret references must use binding ids explicitly allowed by the boundary
- inline sensitive environment values such as API keys and tokens are rejected
- workspace runtime-service mutations are denied unless the boundary explicitly
grants the `runtime.manage` tool class
The Docker workflow in `doc/UNTRUSTED-PR-REVIEW.md` remains useful for manual
local review, but Paperclip-managed low-trust execution requires a sandboxed
environment instead of a host-local adapter process.
