Devin Foley 17dde9d3f2 fix(sandbox): keep custom-image snapshots applied to config tests, probes, and saves (#9385)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox environments can capture reusable custom images (provider
snapshots) so agents boot with pre-installed tools and CLI logins
> - The custom-image runtime fingerprint check included provider
secret-ref paths (e.g. the Daytona `apiKey`), while capture-time
fingerprinting excluded them, so any config carrying a credential never
matched its captured snapshot
> - As a result, agent config tests and environment probes silently
booted the provider base image instead of the snapshot, test sandboxes
were deleted before operators could inspect them, and any environment
save orphaned the snapshot without warning
> - The UI compounded the confusion by displaying an internal template
id that matches nothing in the provider dashboard
> - This pull request aligns runtime fingerprints with capture-time
exclusions, re-stamps fingerprints on saves that cannot affect the
snapshot (warning when they can), archives test/probe sandboxes instead
of deleting them, and surfaces the provider snapshot ref in the UI
> - The benefit is that custom images actually apply to config tests and
probes, survive unrelated config edits, and are debuggable against the
provider dashboard

## Linked Issues or Issue Description

No public GitHub issue exists for this; describing it in-PR per the bug
template. Related: Refs #9329 (saved-environment probe company context —
this branch carries an equivalent fix), Refs #8794 (introduced reusable
sandbox custom images).

**What happened?**

With a Daytona environment whose provider config stores the API key as a
secret reference and an active captured custom-image snapshot:

- Agent config tests and environment probes booted the provider base
image (`daytonaio/sandbox:0.8.0`) instead of the captured snapshot, so
CLI upgrades/logins baked into the snapshot were missing and the probe
reported "login required" and an outdated CLI.
- The environment card showed an internal template id (e.g.
`b5be03e1-ca5…`) that does not correspond to any snapshot name in the
provider dashboard, making the active image impossible to correlate.
- Test/probe sandboxes were deleted immediately after the run, so the
sandbox a test used could not be inspected afterwards.
- Saving the environment config (even fields unrelated to the image)
changed the stored fingerprint, silently detaching the snapshot with no
warning.

**Expected behavior**

Config tests and probes boot the captured snapshot when one is active;
the UI shows the provider-facing snapshot/template ref; test sandboxes
stay inspectable for a short window; unrelated config edits keep the
snapshot linked, and edits that genuinely invalidate it produce an
explicit warning.

**Steps to reproduce**

1. Configure a sandbox environment on Daytona with the API key stored as
a company secret reference.
2. Capture a custom image snapshot from the environment page and mark it
active (e.g. after installing/logging into a CLI in the setup sandbox).
3. Run the agent config test or an environment probe: the sandbox boots
the base image, not the snapshot, and the sandbox is deleted immediately
after the test.
4. Save the environment config with an unrelated field change: the
snapshot silently stops applying.

**Paperclip version or commit**

`master` at the merge-base of this branch.

**Deployment mode**

Self-hosted local instance (macOS, pnpm dev server) with the Daytona
sandbox provider plugin.

## What Changed

- Runtime custom-image fingerprint checks now exclude provider
secret-ref paths, matching capture-time exclusions, so configs carrying
credentials match their captured snapshots
(`environment-custom-image-runtime.ts`).
- Agent config tests and saved-environment probes force fresh,
non-reused sandboxes and pass company context so lease-backed probes can
resolve company secrets and boot the real snapshot
(`environment-probe.ts`, `routes/agents.ts`, `routes/environments.ts`).
- Test/probe sandboxes are released by archiving (stop + 60-minute
provider-side auto-delete) instead of immediate deletion, so operators
can inspect the exact sandbox a test used (Daytona plugin).
- On environment PATCH save, changes that cannot affect the captured
snapshot re-stamp the template's source fingerprint so the snapshot
stays linked; boot-source or provider-identity changes (new manifest
field `templateIdentityPaths`) mark the template detached and the save
response reports it (`environment-custom-images.ts`, shared plugin
types/validators).
- The custom-image overview exposes `activeTemplateMatchesConfig`; the
environments UI shows the provider snapshot/template ref (internal id
moved to a tooltip), warns via toast when a save detaches the snapshot,
and shows a persistent "Not in use" warning when the active template no
longer matches the saved config (`CompanyEnvironments.tsx`,
`api/environments.ts`).

## Verification

- `pnpm vitest run
server/src/__tests__/environment-custom-images-service.test.ts
server/src/__tests__/environment-probe.test.ts
server/src/__tests__/environment-routes.test.ts
server/src/__tests__/agent-test-environment-routes.test.ts` — server
coverage for fingerprint exclusions, re-stamp/detach on save, probe
company context, and fresh-sandbox test behavior.
- `pnpm vitest run
packages/plugins/sandbox-providers/daytona/src/plugin.test.ts` —
archive-on-release and snapshot ref handling.
- `pnpm vitest run ui/src/pages/CompanyEnvironments.test.tsx` — snapshot
ref display, detach toast, and "Not in use" warning.
- Manually verified end-to-end on a live self-hosted instance against
real Daytona: config test boots the captured snapshot (CLI login and
version persist), the test sandbox remains visible in the provider
dashboard as archived, and saving unrelated fields keeps the snapshot
applied.

## Risks

- Fingerprint exclusion widening: a provider credential rotation alone
no longer detaches a captured snapshot; that is the intended behavior
(the snapshot content does not depend on the credential), and
provider-identity fields (e.g. Daytona `apiUrl`) still detach via
`templateIdentityPaths`.
- Archived test sandboxes consume provider-side resources for up to
their auto-delete window instead of being freed immediately; bounded (60
minutes) and only for test/probe sandboxes.
- New optional manifest field `templateIdentityPaths` is
backward-compatible; providers that omit it keep current matching
behavior.

## Model Used

- Claude Fable 5 (`claude-fable-5`), extended thinking, agentic tool use
via Claude Code / Claude Agent SDK.
