Devin Foley 0e51fa2b0d Honor reuse-existing preference and assignee default environment in issue runs (#5139)
## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - Agents run inside execution workspaces (a per-issue cwd + env), and
an issue
> can prefer to reuse an existing workspace or get a fresh one each time
> - The heartbeat service was reading the existing workspace's config to
derive
> environment selection regardless of whether the issue actually wanted
to reuse
> it. So fresh-run issues were inheriting stale config from a workspace
that was
>   about to be discarded
> - Separately, when an issue is assigned to an agent, the issue's
execution
> workspace settings weren't picking up the agent's
`defaultEnvironmentId`,
>   even though the agent's choice is the natural default for that issue
> - This PR makes both selection paths honor the obvious source of
truth:
> workspace config flows only when the issue actually wants
`reuse_existing`,
> and the assignee agent's default environment is applied at assignment
time if
>   nothing else is set on the issue
> - The benefit is that re-running a flaky issue picks up the right
environment
> instead of inheriting the previous run's config, and assigning an
agent to an
>   issue does the obvious thing without operator intervention

## What Changed

- `server/src/services/heartbeat.ts`: introduce
`reusableExecutionWorkspaceConfig`
  that is non-null only when `shouldReuseExisting` is true. Both
  `resolveExecutionWorkspaceEnvironmentId(...)` and
`applyPersistedExecutionWorkspaceConfig(...)` now read from it instead
of
unconditionally consulting `existingExecutionWorkspace?.config`.
Fresh-run
issues no longer inherit stale environment config from an in-flight
workspace
  about to be discarded.
- `server/src/services/issues.ts`: when an issue update sets a new
  `assigneeAgentId` and isolated workspaces are enabled, populate
  `executionWorkspaceSettings.environmentId` from the assignee agent's
  `defaultEnvironmentId` if the issue doesn't have an explicit
  `environmentId` set yet.
- Tests added in `heartbeat-plugin-environment.test.ts` (~216 lines) and
  `issues-service.test.ts` (~85 lines) covering both paths.

## Verification

- `pnpm --filter @paperclipai/server test --
heartbeat-plugin-environment issues-service`
- Manual QA: assign an issue to an agent that has a non-default
`defaultEnvironmentId`, confirm the issue's workspace settings now
include that
environment id without operator intervention. Trigger a rerun on an
issue
whose existing workspace points at a stale environment, confirm the
rerun uses
  the freshly-resolved environment.

## Risks

- Behavioural shift on assignment: previously assigning an agent didn't
propagate the agent's default environment to the issue. Now it does.
Callers
that explicitly want the issue to keep its existing/null environment
must set
`executionWorkspaceSettings.environmentId` themselves; the new logic
only
  fires when no explicit value is set.
- Behavioural shift on rerun: stale workspace config is no longer
applied to
  fresh runs. Operators who relied on this implicit inheritance may see
different environment selection on the first rerun after deploy.
Mitigation:
the explicit isssue settings and project policy are still honored as
before.

Devin Foley 70679a3321 Add sandbox environment support (#4415)
## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies.
> - The environment/runtime layer decides where agent work executes and
how the control plane reaches those runtimes.
> - Today Paperclip can run locally and over SSH, but sandboxed
execution needs a first-class environment model instead of one-off
adapter behavior.
> - We also want sandbox providers to be pluggable so the core does not
hardcode every provider implementation.
> - This branch adds the Sandbox environment path, the provider
contract, and a deterministic fake provider plugin.
> - That required synchronized changes across shared contracts, plugin
SDK surfaces, server runtime orchestration, and the UI
environment/workspace flows.
> - The result is that sandbox execution becomes a core control-plane
capability while keeping provider implementations extensible and
testable.

## What Changed

- Added sandbox runtime support to the environment execution path,
including runtime URL discovery, sandbox execution targeting,
orchestration, and heartbeat integration.
- Added plugin-provider support for sandbox environments so providers
can be supplied via plugins instead of hardcoded server logic.
- Added the fake sandbox provider plugin with deterministic behavior
suitable for local and automated testing.
- Updated shared types, validators, plugin protocol definitions, and SDK
helpers to carry sandbox provider and workspace-runtime contracts across
package boundaries.
- Updated server routes and services so companies can create sandbox
environments, select them for work, and execute work through the sandbox
runtime path.
- Updated the UI environment and workspace surfaces to expose sandbox
environment configuration and selection.
- Added test coverage for sandbox runtime behavior, provider seams,
environment route guards, orchestration, and the fake provider plugin.

## Verification

- Ran locally before the final fixture-only scrub:
  - `pnpm -r typecheck`
  - `pnpm test:run`
  - `pnpm build`
- Ran locally after the final scrub amend:
  - `pnpm vitest run server/src/__tests__/runtime-api.test.ts`
- Reviewer spot checks:
  - create a sandbox environment backed by the fake provider plugin
  - run work through that environment
- confirm sandbox provider execution does not inherit host secrets
implicitly

## Risks

- This touches shared contracts, plugin SDK plumbing, server runtime
orchestration, and UI environment/workspace flows, so regressions would
likely show up as cross-layer mismatches rather than isolated type
errors.
- Runtime URL discovery and sandbox callback selection are sensitive to
host/bind configuration; if that logic is wrong, sandbox-backed
callbacks may fail even when execution succeeds.
- The fake provider plugin is intentionally deterministic and
test-oriented; future providers may expose capability gaps that this
branch does not yet cover.

## Model Used

- OpenAI Codex coding agent on a GPT-5-class backend in the
Paperclip/Codex harness. Exact backend model ID is not exposed
in-session. Tool-assisted workflow with shell execution, file editing,
git history inspection, and local test execution.
