Devin FoleyandPaperclip 724fa6144d fix(opencode-local): preserve the agent during sandbox tool OOMs (#17398)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The Legacy OpenCode adapter runs an agent and its shell tools in the
same sandbox.
> - A large build can exceed the sandbox memory limit and trigger a
kernel OOM kill.
> - The kernel can kill OpenCode before its tool, which loses the active
turn.
> - OpenCode provides a shell environment hook that can change only the
tool subprocess.
> - This pull request uses that hook to prefer Bash tool processes as
OOM victims.
> - The benefit is that OpenCode can report a failed tool and continue
the task.

## Linked Issues or Issue Description

**What happened?**

An OpenCode sandbox run ended with exit 137 after a TypeScript process
had also been killed. Its cgroup limit was 4 GiB. It had completed
useful tool work and had not reached its execution deadline. The
original sandbox was deleted, so its historical OOM counters are
unavailable. Memory pressure is the leading explanation, not a proven
historical kernel diagnosis.

**Expected behavior**

When a shell tool exhausts sandbox memory, the kernel should prefer that
tool over OpenCode where possible. The adapter must preserve configured
shell startup, model, permissions and resource limits.

**Steps to reproduce**

Use a disposable 4 GiB Linux sandbox with OpenCode. Retain a 1,200 MiB
buffer in the agent and run a Bash tool with fourteen 250 MiB workers.
Compare the same workload before and after installing the generated
hook. Record the cgroup memory events, agent exit and final response.

Refs: #16844. That PR covers the same protection for Claude. This PR
adds the OpenCode-owned hook. Refs: #17254 for the separate shutdown
recovery path. This PR does not change retry policy.

## What Changed

- Generate a dependency-free OpenCode `shell.env` plugin and a Bash
startup file in the isolated runtime config.
- Stage those assets only for sandbox execution. Resolve the startup
file relative to the copied plugin.
- Set child `oom_score_adj` to `1000` on Linux. Keep the parent
environment unchanged and honor existing `BASH_ENV` values, including an
empty value.
- Keep command execution available if the optional plugin cannot be
installed or the process priority cannot be changed.
- Materialize linked plugin directories inside the isolated config
before writing. Keep the operator directory and its plugins unchanged.
- Cover relocation, shell output and exit status, operator settings,
local execution, remote staging and failed installation. Update the
adapter documentation and verification recipe.

## Verification

- Red before the fix: the new runtime regression failed because the
sandbox shell plugin was absent. The existing 15 runtime config tests
passed. The same regression passes with the fix.
- Apex first found a host-write risk through linked plugins directories
(4/5). A new regression reproduced the host directory modification, then
passed after the installer materialized the copied link. The finding is
resolved. Apex reviewed current head
`df82a8f51725a197c0ea3ebeb942488509f32b34` at 5/5 with no actionable
issues remaining.
- The full OpenCode adapter suite passes: 87 source tests. The adapter
typecheck and map checks pass.
- Real sandbox acceptance used the plugin generated from
`df82a8f51725a197c0ea3ebeb942488509f32b34` and OpenCode 1.18.34 in a
disposable 4 GiB Daytona sandbox. A controlled local model endpoint
issued an actual Bash tool call; no real model credentials were used.
The tool reported priority `1000`; the parent reported `0`.
- Controlled OOM comparison: without the guard, OpenCode was killed by
SIGKILL after 8.95 seconds and the cgroup recorded one OOM kill. With
the guard, five workers were killed, OpenCode exited `0` after 21.87
seconds, and its final response was `fixture-complete`. The cgroup
counter increased by five. Both attempts used the same allocation and
workload. The fixture started with a linked operator plugins directory.
The installer preserved that directory, staged a real plugins directory,
and passed both the process-priority probe and OOM comparison. The
fixture allocation was deleted afterward.
- The first live probe was not accepted because the harness could not
parse the provider response framing. After correcting the decoder, the
unchanged plugin passed the probe and the controlled OOM comparison.
Both initial disposable allocations were deleted. After the review fix,
a third allocation repeated the probe and OOM comparison with a linked
plugins directory. That allocation was also deleted. The initial
comparison had the same agent-killed/agent-survived result (8.42 seconds
without the guard; 19.42 seconds with it).
- Repository `pnpm -r typecheck` and `pnpm build` pass. The full CI
matrix passes on `df82a8f51725a197c0ea3ebeb942488509f32b34`, including
tests, browser shards, Runner checks, build, policy and Apex. [CI
run](https://github.com/paperclipai/paperclip/actions/runs/40043947375).
- The first full local test attempt had 15 embedded PostgreSQL startup
failures. Direct `initdb --version` and `postgres --version` probes
showed missing bundled library symlinks and SIGABRT. Running the bundled
symlink hydration script restored both executables. All 15 affected
cases pass after that setup repair. No product code changed for it.
- Two existing workspace tests assumed that new Git repositories have no
`main` branch. They failed under the host default branch setting of
`main`, then passed with a per-command `init.defaultBranch=master`
setting. The global setting was preserved. The full local test command
was restarted with hydrated libraries and that controlled fixture
default. It had no reported assertion failures when it was stopped after
the complete CI matrix passed. It did not complete locally; full-suite
verification comes from CI. The first failed invocation was also
stopped.
- The original tenant task has not been retried or recovered by this PR.
Its board API credential is expired. The original hosted workflow and
the separate shutdown recovery remain outside this acceptance result.

## Risks

- This is a preference, not a memory reservation. It cannot guarantee
that OpenCode survives every OOM condition, including memory growth
inside OpenCode itself.
- The guard applies to non-interactive Bash tools. Other shells ignore
`BASH_ENV`. Existing operator startup settings take precedence.
- Older OpenCode releases without the shell environment hook will not
apply the preference. No model, permission, deadline, memory quota or
retry limit changes.
- No schema change or migration.

## Model Used

OpenAI GPT-6 through Codex, with repository tools and code execution.
The exact deployment variant and context window are not exposed by this
session.

Devin FoleyandPaperclip 0ba88d2195 fix(opencode-local): preserve deadlines in Daytona process sessions (#15905)
## Thinking Path

> - Paperclip manages work done by AI agents.
> - The OpenCode adapter can run its CLI in a provider sandbox.
> - A long CLI run must remain observable until it exits or the host
stops it.
> - The legacy main command does not request a provider process session.
A launch without an active run step uses one synchronous command
request.
> - That request can lose its response before the resolved execution
budget ends.
> - This PR requests the existing asynchronous session path for the main
Daytona OpenCode command. It also carries the resolved command deadline
through the host and provider contracts. The host still applies the
effective capability gate.
> - The change removes that synchronous request from eligible sandbox
runs.

## Linked Issues or Issue Description

Related reporting fix: #15789. A search of open and closed GitHub issues
and PRs found no duplicate transport fix.

**What happened?**

A hosted Linux legacy OpenCode run retained a gateway-timeout response
about one hour after CLI startup. It had a four-hour resolved budget and
recent agent output. The earlier reporting fix correctly kept the
configured policy separate from the timeout message. The original
response owner and specific timer were not retained, so this PR does not
claim to prove that provider cause.

**Expected behavior**

A Daytona target that supports persistent process sessions should
dispatch the long agent command asynchronously. Paperclip should observe
its output and exit through the existing session path. A single command
HTTP request should not need to stay open for the full agent run.

**Steps to reproduce**

1. Use legacy OpenCode with a Daytona sandbox target and a four-hour
execution budget.
2. Launch outside an active measured step. The current main CLI call
does not request a persistent process session.
3. In the SDK fixture, make the synchronous command request return a
provider timeout before the budget ends. Keep the asynchronous session
healthy for more than one hour.
4. The regression tests require session dispatch, incremental output,
one command dispatch, a real exit result, and session cleanup.
5. Set a shorter command deadline and stall dispatch, a status read or a
log snapshot. The command must return a timeout at its own deadline.
Healthy output must not extend that deadline.

**Paperclip version or commit**

Observed source: `e733bddc45e00efb1819fffa8677f7b0d07802c5`. PR base:
`4b59e2a2ecc67e98b336b8eb4c09959681672d54`.

**Deployment mode**

Hosted Linux server, legacy OpenCode adapter, Daytona sandbox. The host
gate retains the old path when a provider cannot keep process sessions.

## What Changed

- Add an optional sandbox session choice to the shared process helper.
Leave the choice absent for existing callers.
- Request that session only at the main Daytona OpenCode CLI invocation.
Keep probes, preparation and other providers on their existing paths.
- Carry a separate optional command deadline through the shared runner,
host service and plugin SDK. Existing session callers can omit it. Zero
leaves the command deadline disabled.
- Bound dispatch, live output and recovery observations with one command
timer. Clear it on settlement. Fence late stream callbacks. Remove
deadline listeners after each read and clear interrupted polling waits.
Preserve a known exit code if only the final logs time out. A timeout
result does not claim that the process stopped.
- Add adapter and process-helper regression coverage. Test the existing
Daytona session for a virtual run beyond one hour, without command
replay, with release cleanup.
- Document transport selection and the limits of the timeout evidence.

## Verification

- `pnpm -r typecheck` passed on Node 25.6.1 and pnpm 9.15.4 with the
command deadline changes.
- `pnpm build` passed with the updated contracts. The separately
installed Daytona package also passes its own typecheck and build
against the pinned SDK 0.203.0 and TypeScript 5.9.3.
- Five focused process, adapter, host and provider suites passed all 349
tests. They cover a run beyond one hour, five stalled observation
phases, healthy-stream deadlines, zero/absent budgets, late callbacks,
session release, SSH and capability fallback.
- The real environment-runtime forwarding tests passed: 19 selected
tests, including the separate command budget and forced session flag in
the worker RPC.
- An earlier full local `pnpm test:run` began before a clean build and
overlapped the correction. That mixed-version run was stopped and is not
passing evidence. After the build, the two previously uncollected suites
pass (1,659 tests). Two unchanged workspace fixtures fail with this
machine's Git default branch `main`; both pass with a test-process-only
`master` override. One unchanged native recovery fixture fails on both
this branch and an independently installed and built checkout of base
`4b59e2a2ecc67e98b336b8eb4c09959681672d54`, with the same
terminal-result mismatch. It is not introduced by this change. The full
local suite is not claimed green. These limitations do not replace fresh
hosted CI.
- Final head `8e96638cdef8ca6e91f7a42a52c83a075180c137` passes all
hosted checks: 54 passed and 2 expected Storybook skips. Greptile
reviewed this exact head at 18:12 UTC and scored it 5/5. Both actionable
findings are fixed and resolved. GitHub reports no conflicts and a clean
merge state. Earlier-head results are not used as final-head proof.
- The standalone provider test command passes 373 tests, with 14
expected live-probe skips.
- SDK tests use a controlled virtual clock. No live provider experiment,
task replay, manual deployment, or public PR merge was performed.

## Risks

The main legacy OpenCode command uses Daytona's existing session route
when the effective capability gate permits it. A quiet log stream can
use the existing status and snapshot fallback. Those observations add
provider reads. The new optional command budget is separate from each
read's timeout and returns a timeout without the host RPC's extra
30-second allowance. Existing session callers that omit it keep their
previous lifetime.

Callback bridge control commands retain their explicit session bypass.
The capability gate retains the previous path for unsupported targets.
Other providers, local and SSH execution keep their existing path. Retry
policy, Stop acknowledgement and lease ownership rules stay the same.
The SDK exposes no cancellation handle for an abandoned stream; existing
Stop and lease teardown still own command termination. This fix does not
establish the original gateway owner or prove recovery in a live
environment.

## Model Used

OpenAI Codex, based on GPT-6, with reasoning, repository tools and code
execution. The exact backend identifier and context window size are not
exposed by this session.

Devin FoleyandPaperclip caa7895f9a fix(opencode): report timeouts without claiming deadline expiry (#15789)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The OpenCode adapter reports the outcome of a local or remote
execution.
> - A provider can report a timeout before the configured execution
deadline.
> - The adapter treated every timeout as proof that the configured
deadline expired.
> - This pull request uses a generic timeout message and retains the
resolved policy.
> - Operators can compare the run duration with its actual configured
limit without a false cause claim.

## Linked Issues or Issue Description

**What happened?**

A remote execution can return `timedOut: true` after a short interval
while the sandbox policy is four hours. OpenCode reported `Timed out
after 14400s`. It also dropped the resolved policy on that result. Run
finalization then used the raw `timeoutSec: 0` configuration, so
diagnostics incorrectly reported an unlimited timeout.

**Expected behavior**

Keep the timeout outcome. Report the resolved policy separately from the
failure message. Do not infer which timer fired from the provider's
boolean or stderr.

**Steps to reproduce**

Call the OpenCode adapter with a sandbox execution target and
`timeoutSec: 0`. Return a timed-out process result before four hours.
Inspect the message and the policy that finalization sends to the
run-failure collector. The new tests reproduce this with local fixtures
and an in-memory Sentry transport.

**Paperclip version or commit**

Reproduced on `de042e79efbb7bb88e9716835407882e3ebab188`.

**Deployment mode**

Legacy OpenCode execution on a local instance or remote sandbox.

Refs #14832 for related timeout result preservation; this PR does not
change session state. Related PRs #14964, #15659 and #15715 cover
silent-run limits, gateway requests and OpenCode v2 support. They do not
fix this policy/message path.

## What Changed

- Retain the complete existing timeout resolution on both OpenCode
result branches.
- Report `OpenCode execution timed out` without copying provider output
into exception text.
- Document that configured policy and the existing `timeoutFired`
outcome field do not prove timer origin.
- Test policy overrides, sandbox defaults, opt-out, ordinary exits, real
local timer expiry, cleanup and real Sentry SDK delivery.

## Verification

- 142 focused adapter, stop-metadata and diagnostic tests passed on Node
25.6.1.
- The real Sentry SDK contract suite passed 11/11 with the audited
optional peer 10.71.0 and an in-memory transport. The new test runs the
actual adapter, finalization policy merge and collector. It verifies
that raw HTML and credential canaries stay out of the event and
unrelated captures stay isolated.
- Full workspace `pnpm -r typecheck` and `pnpm build` passed. All hosted
CI checks passed on `f4df5cba1d2223d444559de960bbf88dfa985bbf` (54
passed, 2 expected skips).
- The local aggregate is not a pass: 15 existing PostgreSQL fixture
cases initially failed because this fresh macOS install lacked bundled
ICU symlinks. The dependency's existing hydration script repaired the
isolated install; all 15 affected cases then passed with real
PostgreSQL. No test or production source was changed for that setup
issue. The aggregate was stopped after hosted test coverage passed; it
is incomplete, not a local full-suite pass. All owned test processes
exited.
- Greptile scored this exact head 5/5 with no review threads.
Independent review found no issues. It ran 58 positive cases and adapter
typechecking. Three negative controls failed as expected when it
restored the old producer, removed timeout policy, or copied raw stderr
into the message.

## Risks

The timeout message changes for local and remote OpenCode runs. The
resolved policy is additive result data. The numeric timeout, grace
period, process result, retry rules, session handling, cleanup and
recovery behavior are unchanged. This fixes reporting and does not
identify or fix an upstream provider timeout. No schema change or
migration is required.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository tools and
independent agent review. The exact service model identifier and
context-window size are not exposed in this session.
