DottaandClaude Opus 5.5 1b7ec13acb perf(native): default remote sandbox runs to a warm, reusable sandbox for measured harnesses (#20048)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents can run in remote sandboxes (Daytona), where each turn needs
the task's workspace and a runner inside the sandbox
> - With a default environment, every remote turn got a brand-new
sandbox: the whole workspace was uploaded again and a new runner
started, even for a follow-up comment
> - In a paperclip-sized workspace that made a follow-up take 30 s to
first token, against 8–10 s with a reusable warm sandbox
> - This pull request makes an agent that never chose a lifecycle run
warm on a sandbox for the measured harnesses (Codex, OpenCode, Claude),
so a follow-up keeps its sandbox, runner and workspace
> - The default applies only where warm can work: a sandbox provider
that keeps reusable leases, and a managed AI account that supports a
warm session. Everywhere else the run is per-turn, exactly as before
> - The benefit is fast remote follow-ups by default, without
re-uploading a large repository every turn

## Linked Issues or Issue Description

**What happened?**
On Daytona, with a fresh paperclip clone as the project workspace, a
follow-up comment took 30 s to its first token. The run log showed
`environment: fresh/created` on every follow-up. It spent 13.3 s in
`workspace_sync.transfer`, a full upload into the new sandbox, and 8–9 s
in `runner.session.resume`.

**Steps to reproduce**
1. Create a Daytona environment with the defaults: lifecycle inherited,
lease reuse off.
2. Run a Codex task in a large repository, then post a follow-up.
3. The follow-up gets a new sandbox, uploads the whole workspace again
and starts a new runner.

**Expected behavior**
A follow-up on the same task reuses the live sandbox, its runner and its
workspace (plan rule 2: no full re-upload per turn).

## What Changed

- **One rule for the default.** `defaultsRemoteSandboxRunToWarm`
(`native-runtime/native-warm-capability.ts`) decides the remote-sandbox
warm default for both the lease (environment view) and the runner
(native session policy), in one vocabulary (runtime backend plus ACPX
agent). It is applied only when no lifecycle was chosen anywhere:
admitted session, environment `runnerLifecycleMode`, or agent
`lifecycleMode`. It holds only when:
  1. the harness is measured (Codex, OpenCode, ACPX Claude);
2. the sandbox provider keeps reusable leases (Daytona, CreateOS and
boxd declare them; E2B, Modal and the built-in `fake` do not); and
3. with a managed AI account, that harness supports a managed warm
session (`supportsManagedNativeWarmSession`: Codex).
- **The harness resolves as the runtime resolves it.**
`resolveWarmProviderSelection` uses
`resolvePaperclipRunnerProviderProfile`, so an omitted `provider` is
Codex and ACPX without an agent is Claude, in both decisions. A config
the runtime would refuse gets no default.
- **Lease side** (`runner-environment-lifecycle.ts`,
`environment-run-orchestrator.ts`): for an eligible run only, the
orchestrator asks the provider before acquisition
(`providerSupportsReusableLeases` in `environment-runtime.ts`: the
acquisition rule, one registry lookup for a plugin provider, no
worker-ready wait). With support, the run-scoped view sets `reuseLease:
true` and forwards the warm idle window to the provider's auto-stop. The
shared environment is never rewritten. Every other run resolves exactly
as on master, without the probe.
- **Runner side** (`native-lifecycle.ts`, `runtime-selection.ts`): the
native policy applies the same rule to the acquired lease
(`reusableLeaseConfigured && effectiveCapabilities.reusableLeases`). If
acquisition downgrades the lease anyway, the run falls back to per-turn;
a default never produces
`runner_warm_environment_requires_reusable_lease`.
- **Idle window.** The remote default uses the window the environment
view forwards to the provider: an inheriting environment's
`runnerIdleTimeoutMs`, then the agent's `idleTimeoutMs`, then 5 minutes.
The sandbox execution target now carries the environment's window
(`runnerIdleTimeoutMs`, an optional field in `adapter-utils`'s execution
target) so the runner and the provider auto-stop agree. An explicit warm
choice and the local default are unchanged.
- Unchanged: explicit agent choices, environments that pin a lifecycle,
plugin-task environments, admitted sessions (`persistedPolicy`), and
local behavior.
- `tests/restart-chaos`: the vCPU budget check counts `--daytona-inherit
--lifecycle default` sandboxes as retained, because they now default to
warm.
- `doc/plans/2026-11-08-large-workspace-speed.md`: the measurements, the
ranked waits, and the gate.

## Verification

- Unit and integration tests, one per rule:
- Rule 1 (provider gate): `native-lifecycle.test.ts` (ephemeral lease →
per-turn), `runner-environment-lifecycle.test.ts` (no reusable leases →
environment unchanged, no warm window),
`environment-runtime-reusable-lease-probe.test.ts` (`fake`, an
undeclared plugin, a declared plugin whose worker does not verify the
reuse methods, and a plugin without a running worker read false),
`runtime-selection.test.ts` ("defaults an agent without a lifecycle on
...": reusable → warm/keep_running; reuse configured on an unsupported
provider → per_turn/destroy_after_turn; ephemeral → per_turn),
`environment-run-orchestrator.test.ts` (probe result decides
`reuseLease` and the forwarded window).
- Rule 2 (explicit configuration wins): explicit per-turn agent, pinned
environment, admitted session, configured `idleTimeoutMs`, managed
Claude per-turn, managed Codex warm; the orchestrator does not probe
when a lifecycle is explicit.
- Rule 3 (omitted provider): `{}` resolves to Codex in the environment
view; `runtime-selection.test.ts` "agrees with the environment view's
lease for ..." feeds the environment view's lease into selection for
Codex, a provider-less Codex agent, OpenCode, ACPX Claude, ACPX without
an agent, and Copilot (per-turn), and checks both decisions agree. A
plugin-task target stays out of the default.
- The two suites that failed on the previous head
(`runtime-selection.test.ts`,
`workspace-recovery-preparation-dispatch.test.ts`) pass locally.
Locally, 6 connector-skill cases in `runtime-selection.test.ts` fail
with `ENOENT .claude/skills/slack/SKILL.md` because this checkout is a
nested worktree; they do not touch this change and pass in CI.
- End-to-end check of this default on Daytona (before the gate was
added; Daytona keeps reusable leases, so the gate does not change this
path): a user-default environment (lifecycle inherited, lease reuse
unset, `--daytona-inherit`), a fresh paperclip clone, built from the
image's source revision with this change (branch measure/remote-warm).

  | | Before (per-turn sandbox) | After (this change) |
  |---|---|---|
  | Follow-up, Codex | 30.4 s | 7.6 s |
  | Follow-up, Claude | about 30 s | 11.0 s |
  | First follow-up after an idle K1, Codex | 45.9 s | 20.3 s |
  | First follow-up after an idle K1, Claude | 38.3 s | 18.3 s |

The run-log reuse records show the follow-ups reusing the workspace,
environment, runner and provider session, with no
`workspace_sync.transfer`. First turns still upload the workspace once
(14.8 s and 26.1 s). Every sandbox was cleaned up.
- Daytona restart chaos wave (K1/K2/K4 with a mid-run comment,
inheriting environment, agents with no lifecycle, runner image built
from this branch): wave `w-20261110T171438-s20048`, seed 20048, on
b7f6243d60 with image `paperclip-daytona-runner@sha256:76a33275…6fe29`
(built from this branch by the `image_only` runner workflow; runner
content id `ed503454…a479` matches every later commit here, which change
only server, adapter-utils types and tests). `--daytona-inherit
--lifecycle default --adapters codex,claude --workloads A1,C1 --triggers
time,comment --faults K1,K2,K4 --tasks 6 --concurrency 3`.
- **6/6 tasks pass** (R1–R6 and T), all 6 crossed a restart; cells:
Codex A1 K2, Codex A1 K4, Claude A1 K4, Claude C1 K1, Claude C1 K4,
Codex C1 K2 at the mid-run comment. **No task needed Retry** (R3 n/a on
every task; one Claude task recovered automatically from
`process_lost`). No open signatures, 0 speed breaches.
- The default applied: the R6 sweep found 6 retained reusable leases
(one per task, Daytona keeps them) and no orphan or leaked sandbox; the
environment was deleted cleanly.
- Timings (Daytona, first turns, n=3 each): TTFT p50 Codex 21.9 s,
Claude 31.0 s. Restart recovery p50/p95: Codex 10.5 s / 29.6 s (n=3),
Claude 8.8 s / 23.9 s (n=2). Warm follow-up TTFT has no clean sample in
this wave (both follow-ups were crossed by a fault), so the follow-up
comparison above (30.4 s → 7.6 s Codex, ~30 s → 11.0 s Claude) remains
the speed evidence; no separate per-turn chaos wave was run.
- An earlier attempt, `w-20261110T170357-s20048`, never started tasks:
the first sandbox from the new image stayed `creating` past the
harness's 300 s Codex qualification bound (Daytona building the new
snapshot). It left one sandbox that the harness reported after deleting
the environment; the rerun on the cached snapshot is the wave above.
- The idle-window fix (9a74116082) landed after the wave; it changes
only runs whose inheriting environment sets `runnerIdleTimeoutMs`, which
this wave's environment does not.

## Previous-release story

No persisted state changes shape. A session admitted per-turn before
this change keeps its saved policy (`persistedPolicy` wins) until a new
session starts. A run in flight at the cutover keeps its admitted
lifecycle for recovery (`admittedLifecycleMode` wins in the environment
view).

## Cost and opt-out

- **Cost:** after a turn, the sandbox and its warm runner stay up for
the warm idle window (the environment's `runnerIdleTimeoutMs`, else the
agent's `idleTimeoutMs`, else 5 minutes). Then the controller suspends
the runner, and the provider auto-stop follows the same window. One idle
window per active task.
- **Opt-out:** set the agent's lifecycle to "Turn by turn"
(`lifecycleMode: per_turn`), or set the environment's
`runnerLifecycleMode` to `per_turn`. Either wins over this default.

## Reuse scope, restart and saved work

- **One lineage per sandbox.** The Daytona plugin keys a reusable lease
by the agent plus the execution workspace (or issue). Another task never
gets a sandbox holding a different task's files, and subtasks still get
fresh workspaces from the project base, so they get their own sandbox.
The workspace is adopted only after its stamp matches the host's.
- **After a restart,** a warm sandbox is reattached or replaced through
the existing warm recovery and owner fencing. A sandbox with a live
owner is never claimed twice. The Daytona chaos wave above checks this.
- **No lost work.** Each turn's workspace copyback
(`workspace_finalize`) runs at the end of the turn, before any idle
suspend, as for per-turn runs.

## Risks

- **Cost:** an idle sandbox stays up for the warm idle window (5
minutes) after a turn, then suspends. Only on providers with reusable
leases.
- **Probe cost:** one plugin-registry lookup before acquisition, only
for runs the default can apply to. No wait for a worker: a provider
whose worker is not running yet reads as unsupported, so that run is
per-turn.
- **Known gap (pre-existing, not widened):** with an explicit agent warm
choice on an inheriting environment that sets `runnerIdleTimeoutMs`, the
provider gets the environment's window while the host uses the agent's,
as on master.
- **Restart behavior on warm remote sandboxes** uses the existing warm
recovery paths. The Daytona chaos wave above checks K1, K2 and K4.
- Sessions admitted per-turn before this change stay per-turn until a
new session starts.

DottaandClaude Opus 5.5 7475577cdb fix(daytona): keep a runner sandbox alive through the controller reconnect grace (#19754)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A remote agent run executes in a Daytona sandbox and keeps working
while the Paperclip server restarts
> - The server reattaches that runner within a 7-minute reconnect grace
> - Daytona stops an idle sandbox after its `autoStopInterval`, and it
counts only SDK and lifecycle calls as activity
> - With the server down, nothing touches the sandbox, so a 5-minute
auto-stop kills the runner before the server returns
> - This pull request makes the host tell the provider its reconnect
grace, so Daytona never auto-stops a runner sandbox inside that grace
> - The benefit is that a controller outage of up to 7 minutes no longer
turns a healthy remote run into a blocked task

## Linked Issues or Issue Description

Refs #19199 (the same floor for the warm runner idle window). Refs
#19741 (follow-up delivery through restarts; no overlap).

**What happened?**
A restart-chaos wave on Daytona killed the server for 4m51s while a
per-turn remote run was active. The environment used `autoStopInterval:
5`. The last sandbox activity was at 06:09:16. The server came back at
06:14:19 and then crashed again. At 06:15:21 recovery called the
sandbox. The plugin found it not started and started it again. The
runner identity marker was still on disk, but its process was gone:
`native.remote_runner_recovery_failed {stage: process_verification,
reason: process_not_running}`, then
`runner_remote_process_identity_unavailable`. The task went from done to
blocked. An earlier wave showed the same failure after a 4m45s outage.

**Expected behavior**
A sandbox that holds a live remote runner survives any controller outage
up to the reconnect grace. The server reattaches the runner and the run
continues.

**Steps to reproduce**
1. Create a Daytona environment with `autoStopInterval: 5` and a
`paperclip_runner` agent.
2. Start a remote run and kill the server for more than 5 minutes (less
than 7).
3. Restart the server. Recovery reports `process_not_running` and the
task becomes blocked.

## What Changed

- `server`: add `resolveRunnerReconnectGraceMsForRun`. It returns
`REMOTE_RUNNER_RECONNECT_GRACE_MS` for `paperclip_runner` on a sandbox
environment.
- `server`: forward `runnerReconnectGraceMs` to the provider worker on
lease acquisition and on the recovery reattach resume. It uses the same
provider-only path as `warmRunnerIdleTimeoutMs`. It is not lease
identity, lease metadata, or saved environment config.
- Daytona plugin: the effective auto-stop is at least the largest host
floor (warm idle window or reconnect grace) plus 5 minutes. With the
current grace this is 12 minutes. The plugin applies it at creation and
raises an older sandbox's shorter interval on resume (bounded, best
effort).
- Daytona plugin: keep the forwarded grace out of the normalized config.
Update the `autoStopInterval` manifest description.
- `doc/execution-semantics.md`: document the reconnect-grace floor next
to the warm floor.

## Verification

- Red/green Daytona plugin tests: `cd
packages/plugins/sandbox-providers/daytona && npx vitest run --config
vitest.config.ts`. The new cases failed before the fix (for example
`expected 120000 to be >= 720000`, and no `setAutostopInterval` call on
resume). All 605 tests pass after the fix.
- Server tests: `cd server && npx vitest run
src/__tests__/environment-run-orchestrator.test.ts
src/__tests__/environment-runtime.test.ts`. 247 pass. They prove
acquisition forwards the grace only for `paperclip_runner` on a sandbox,
that the reattach resume forwards it, and that it does not reach lease
metadata or saved config.
- `pnpm typecheck` for the plugin and `tsc --noEmit` for the server are
clean.
- `pnpm verify` asks for broad CI coverage because a doc changed.
Required CI supplies it.
- Evidence from the kept wave database: lease metadata shows
`autoStopInterval: 5`, `reuseLease: false`, `runnerLifecycleMode:
per_turn`. The run had no events between 06:09:16 and 06:14:19.

## Risks

- Cost: a runner sandbox that leaks (no cleanup) now auto-stops after 12
minutes instead of a shorter configured value. Cleanup still stops or
destroys released sandboxes. Explicit `0` and longer values are
unchanged. Auto-archive and auto-delete are unchanged.
- I did not inspect the sandbox state in Daytona directly. Cleanup
destroyed it before this investigation. The proof is the timing, the
lease config, and the `process_not_running` result after a restart that
kept the disk.
- No live Daytona replay ran.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, with tool use (shell,
file edit, code execution) in Claude Code.

DottaandClaude Opus 5.5 037c58bb22 fix(daytona): keep the provider auto-stop strictly after the warm runner idle window (#19199)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A warm remote agent keeps its sandbox running after a turn. The host
keeps a warm runner for an idle window (`runnerIdleTimeoutMs`, or the
agent's `idleTimeoutMs`)
> - The Daytona provider also stops an idle sandbox after
`autoStopInterval` minutes. The default is 15 minutes
> - On staging, the warm idle window was 900,000 ms (15 minutes). The
two windows were equal
> - A follow-up turn at the end of the warm window resumed a sandbox
that Daytona was stopping. Daytona refused the resume in about 4
seconds, and the run failed at setup
> - #19195 added a bounded retry for that refusal. It did not remove the
cause
> - This pull request makes the two windows non-overlapping by
construction. Daytona derives its auto-stop for a warm reusable sandbox
from the same warm idle value that the host uses
> - The benefit is that a follow-up inside the warm window always finds
a running sandbox, and idle sandboxes still stop

## Linked Issues or Issue Description

Refs #19195 (bounded retry for a refused resume; this change removes the
common cause).

**What happened?**

On a staging soak, three follow-up runs failed at setup with a refused
sandbox resume. Each resume began 15 minutes 8 to 25 seconds after the
previous turn released the sandbox. The warm idle timeout was 900,000
ms. Daytona's default `autoStopInterval` is 15 minutes. Nothing in the
code kept these two values apart.

**Expected behavior**

A reusable sandbox that keeps a warm runner must not auto-stop inside
the warm idle window or at its edge. The provider backstop must fire
after the host's own idle handling, with a margin. Idle sandboxes must
still stop.

**Steps to reproduce**

1. Configure a Daytona sandbox environment with `reuseLease` and a warm
runner with `runnerIdleTimeoutMs: 900000` (or an agent with
`lifecycleMode: warm`, `idleTimeoutMs: 900000`).
2. Run a turn. Do not set `autoStopInterval`.
3. Before this change: the sandbox is created with `autoStopInterval:
15`, equal to the warm window. A follow-up near minute 15 races the
provider stop.

**Paperclip version or commit**

`c656b95b6b` (current `master`).

## What Changed

- Daytona plugin (`plugin.ts`): add `effectiveAutoStopIntervalMinutes`.
For a reusable lease that keeps a warm runner, the effective auto-stop
is at least `ceil(warm idle / 1 min) + 5` minutes. The plugin applies
the floor only when the host forwards `warmRunnerIdleTimeoutMs`, or when
the environment itself selects `runnerLifecycleMode: warm`. An explicit
`0` (disabled), a longer configured value, `inherit` with a per-turn
agent, per-turn, and non-reusable sandboxes keep the configured value.
- Daytona plugin: use the effective value at sandbox creation. On
resume, raise a shorter auto-stop on an existing sandbox. This update is
best effort and bounded to 5 seconds; the #19195 retry still covers a
refusal. The stale-handle refresh threshold keeps the configured
interval, so a cached handle is not trusted for longer before the
provider confirms the new interval. The warm window is not written to
the saved normalized config.
- Host (`runner-environment-lifecycle.ts`): add
`resolveWarmRunnerIdleTimeoutMsForRun`. It returns the run's effective
warm idle window (environment `runnerIdleTimeoutMs`, else the agent
`idleTimeoutMs`) for a warm `paperclip_runner` sandbox run. It shares
the lifecycle-mode resolution with `resolveRunnerEnvironmentForRun`.
- Host (`environment-run-orchestrator.ts`, `environment-runtime.ts`):
pass that value as `warmRunnerIdleTimeoutMs` to the sandbox-provider
driver on acquisition and on remote recovery resume. The driver adds it
to the provider worker config only. Lease identity, reuse matching, and
lease metadata are unchanged.
- Daytona manifest: describe the warm floor on `autoStopInterval`.
- `doc/execution-semantics.md`: document the contract.

## Verification

- Red (before the fix, same tests, with the floor disabled): 5 failures
in `plugin.test.ts` "warm idle window versus Daytona auto-stop". The
staging case failed with `expected 900000 to be greater than or equal to
1200000`. The resume case failed because `setAutostopInterval` was not
called.
- Red (host): the new `environment-runtime.test.ts` case first failed
because the provider worker config had no `runnerIdleTimeoutMs`. The
service wrapper dropped the field. The fix forwards it.
- Green: `npx vitest run --config vitest.config.ts` in
`packages/plugins/sandbox-providers/daytona`: 563 passed. This includes
a setter that never settles (resume completes after the 5-second bound)
and `inherit` with no forwarded window (explicit `autoStopInterval: 2`
stays 2).
- Green: `npx vitest run
src/services/runner-environment-lifecycle.test.ts
src/__tests__/environment-runtime.test.ts
src/__tests__/environment-run-orchestrator.test.ts` in `server/`: 242
passed. This includes recovery resume forwarding the admitted warm
window.
- The regression tests assert the relationship `autoStop >= warm idle +
margin` for several warm windows (125 s, 300 s default, 900 s, 1,800 s)
and for an explicit `autoStopInterval: 15`. They are not constant
checks.
- `node scripts/typecheck-low-memory.mjs` passes. `pnpm typecheck` in
the Daytona package passes.

## Risks

- A warm reusable Daytona sandbox now stays running up to the warm
window plus 5 minutes after its last activity, instead of 15 minutes.
With a 15-minute window this is 20 minutes. Cost is bounded and idle
sandboxes still stop.
- The resume-time `setAutostopInterval` call is best effort. If it
fails, the old interval stays and the #19195 retry still applies.
- Other providers are unchanged. They receive one extra host-owned
config key (`warmRunnerIdleTimeoutMs`) only for warm `paperclip_runner`
runs, and they ignore unknown keys.
- No lease identity change, so existing retained sandboxes are still
reused.

DottaandPaperclip 640dee1802 fix(runner): acquire reusable leases when switching to warm sessions (#14187)
## Thinking Path
> - Paperclip coordinates agent work across task turns.
> - Warm runners need reusable sandbox leases.
> - Lease acquisition read only the environment reuse setting.
> - Startup then read the agent's new warm setting and rejected the
ephemeral lease.
> - This fix requests reuse before acquisition, with provider checks
intact.

## Linked Issues or Issue Description
**What happened?**
Switching an existing native runner task from per-turn to warm fails
with `runner_warm_environment_requires_reusable_lease`. Environment
`reuseLease` defaults to false. Acquisition therefore creates an
ephemeral lease, and capability narrowing correctly denies reuse.

**Expected behavior**
Changing lifecycle between turns requests a compatible lease without
replacing the task workspace or changing the shared environment.

**Steps to reproduce**
1. Start a native runner task with inherited lifecycle and environment
reuse disabled.
2. Change the agent from per-turn to warm.
3. Continue the task on a reusable-capable sandbox provider.

**Paperclip version or commit**
Reproduced on `a6c4e7a`. Related: #12904 established warm workspace
continuity; this fixes the earlier lease-selection mismatch.

## What Changed
- Pass agent settings into acquisition and derive a run-scoped reuse
request.
- Respect explicit environment lifecycle overrides; leave other adapters
unchanged.
- Keep provider capability, ownership, cleanup and restore gates intact.
- Add orchestration and database-backed transition tests; document the
contract.

## Verification
- Red: three new assertions failed before the fix.
- Green: 156 tests pass in environment-run-orchestrator,
environment-runtime, native-sandbox-lifecycle, and
environment-execution-target-capabilities.
- Database-backed regression proves ephemeral → reusable → resumed
lease, same workspace, and unchanged stored environment. Provider RPCs
are mocked, not live Daytona.
- `git diff --check` passes.
- Latest-head CI passes typecheck, build, tests, runner checks, E2E, and
canary dry run. Greptile: 5/5; no open threads.
- Recovery uses the persisted lifecycle. Direct regression: red before,
six cases green after. CI runs the added Vitest cases.
- Full local checks were unavailable (missing dependencies and earlier
memory limits).

## Risks
Warm mode now requests retained resources despite an environment's
default `reuseLease:false`. Existing idle timeout and cleanup still
apply. Unsupported providers remain denied. No migration, credential
[REDACTED], or shared-environment mutation.

## Model Used
OpenAI Codex agent; reasoning, code editing and test execution. Exact
model ID and context size were not exposed to this run.
