## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - Agent runs execute through adapters (e.g. `acpx_local`), which can run locally, over SSH, or inside sandbox execution targets, each with a wall-clock execution timeout > - Sandbox-backed runs defaulted to a 30-minute wall-clock backstop (`DEFAULT_REMOTE_SANDBOX_ADAPTER_TIMEOUT_SEC = 1800`), which kills healthy long agent runs that are still making progress — long before the recovery watchdog's 4h critical threshold would even consider them stuck > - On top of that, `acpx_local` resolved its timeout directly from `adapterConfig.timeoutSec` instead of the shared execution-target resolver, and its timeout failures surfaced as a bare `Timed out after Ns` — giving operators no clue which timer fired or which knob raises it > - This pull request raises the sandbox backstop to 4h (aligned with the recovery watchdog), routes `acpx_local` through the shared timeout resolver, logs the effective timeout and its source at run start, and makes every timeout error message self-describing > - The benefit is that long-running sandbox agent runs no longer die at 30 minutes, and when a wall-clock timeout does fire, the run log states exactly which timer fired and how to configure it ## Linked Issues or Issue Description Refs #4535 (related: wall-clock execution timeouts killing agent runs that are still making progress — that issue covers a different hardcoded 600s timer, but the operator pain is the same). No exact public issue exists for this one, so describing it in-PR: **Bug:** A long sandbox-backed `acpx_local` agent run was killed with a bare `Timed out after 1800s` even though the agent was actively working. - **What happened:** The run hit the 30-minute `DEFAULT_REMOTE_SANDBOX_ADAPTER_TIMEOUT_SEC` backstop. `acpx_local` never consulted the shared execution-target timeout resolution (it read `adapterConfig.timeoutSec` directly, default 0), so on sandbox targets the sandbox-provider default applied with no adapter-level say. The resulting error named neither the timer that fired nor the knob that controls it. - **Expected:** Healthy long runs should not be killed by a 30-minute wall-clock backstop when the recovery watchdog only treats runs as critically stuck after 4h of output silence; and any timeout error should say which timeout fired and how to raise it. - **Impact:** Long, legitimate agent runs in sandboxes fail mid-work; operators waste time reverse-engineering which of several timers produced "Timed out after Ns". ## What Changed - `packages/adapter-utils/src/execution-target.ts` - `DEFAULT_REMOTE_SANDBOX_ADAPTER_TIMEOUT_SEC` raised from `1_800` to `14_400` (4h), with a comment explaining it intentionally matches the recovery watchdog's `ACTIVE_RUN_OUTPUT_CRITICAL_THRESHOLD_MS` (4h) so the adapter backstop never fires before the watchdog path. Output-inactivity monitors remain the primary hang detectors. - New `resolveAdapterExecutionTargetTimeout(target, configuredTimeoutSec)` returns `{ timeoutSec, source }` where `source` is `configured` / `sandbox_default` / `unlimited`. The existing `resolveAdapterExecutionTargetTimeoutSec` is preserved as a thin wrapper, so current callers are unaffected. - New `formatAdapterExecutionTimeoutErrorMessage(resolution)` and `formatAdapterExecutionTimeoutStartLogLine(resolution)` produce self-describing messages that name the timer that fired and the `adapterConfig.timeoutSec` knob that controls it. - `packages/adapters/acpx-local/src/server/execute.ts` - `buildRuntime` now resolves the wall-clock timeout through the shared resolver: sandbox targets default to the 4h backstop, local/SSH keep the historical "0 = no adapter timeout", and a configured `adapterConfig.timeoutSec` always wins. - The executor logs the effective timeout and its source at run start (`[paperclip] Adapter execution timeout: …`), so a later timeout is diagnosable from the run log alone. - All three bare timeout messages (timer cancel reason, turn result `errorMessage`, catch-path `messageOverride`) now use the self-describing format. - `packages/adapters/acpx-local/src/index.ts` — the adapter configuration doc for `timeoutSec` states the sandbox default and that the output-inactivity monitor remains the primary hang detector. - Tests: `packages/adapter-utils/src/execution-target-sandbox.test.ts` and `packages/adapters/acpx-local/src/server/execute.test.ts` (see Verification). ## Verification - `pnpm --filter @paperclipai/adapter-utils typecheck` — passes - `pnpm --filter @paperclipai/adapter-acpx-local typecheck` — passes - `npx vitest run packages/adapter-utils/src/execution-target-sandbox.test.ts packages/adapters/acpx-local/src/server/execute.test.ts` — 2 files, 40 tests, all pass - New/updated test coverage: - sandbox default resolves to 4h (and the constant is asserted to be `4 * 60 * 60`) - `resolveAdapterExecutionTargetTimeout` reports `configured` / `sandbox_default` / `unlimited` sources with the correct precedence (configured > sandbox default; local/SSH stay unlimited) - exact wording of the self-describing error message and the start-of-run log line - `acpx_local` runtime picks up the sandbox default into `timeoutMs`, keeps the unlimited local default, honors configured-over-default precedence, emits the start-of-run log line, and surfaces the self-describing `errorMessage`/cancel reason when the wall-clock timer kills a turn ## Risks - **Behavioral shift:** sandbox-backed adapter runs that previously hit the 30-minute backstop now run up to 4h before the adapter kills them. Genuinely hung runs are still caught much earlier by the adapters' output-inactivity monitors and by the recovery watchdog; the wall-clock timer is a last-resort kill switch. Operators who relied on the 30-minute default can restore it explicitly via `adapterConfig.timeoutSec`. - **Error-message consumers:** any tooling that pattern-matched the exact `Timed out after Ns` string from `acpx_local` will see the new self-describing message instead. - No API or schema changes; `resolveAdapterExecutionTargetTimeoutSec` keeps its exact signature and behavior (modulo the raised sandbox default). > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
