(`DEFAULT_REMOTE_SANDBOX_ADAPTER_TIMEOUT_SEC = 1800`), which kills
healthy long agent runs that are still making progress — long before the

> - 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

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).

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent adapters are the boundary between the control plane and the
runtimes that actually do work.
> - Hermes support needs to be available as first-class local and
gateway adapters while still preserving the adapter-manager override
path for external packages.
> - The adapter work touches runtime execution, UI adapter metadata,
onboarding prompts, scoped credentials, release packaging, and smoke
coverage, so the handoff needs concrete verification rather than only
unit tests.
> - This pull request adds built-in Hermes local and Hermes gateway
support, keeps external adapter overrides compatible, and
documents/tests the gateway flow end to end.
> - The benefit is that operators can hire Hermes-backed agents without
a manual plugin install, while self-hosted installs can still
override/shadow the built-ins through Adapter manager packages.
## Linked Issues or Issue Description
No public GitHub issue exists for this exact Hermes built-in adapter,
gateway onboarding, and release-source work.
Problem description:
- Hermes local and gateway adapters need a public, reviewable source
path in the monorepo so package artifacts and built-in adapter behavior
match the application source.
- Operators need built-in `hermes_local` and `hermes_gateway` adapter
choices without losing the ability to install external Hermes packages
as overrides.
- Gateway onboarding needs secure defaults for API server URLs, API
keys, and generated agent setup text.
- Hermes-originated task bridge credentials need narrower API-key scope
configuration.
- Related public PRs found during duplicate search include #3027, #2363,
#7544, #7950, #8095, and #8543.
## What Changed
- Added the unified Hermes adapter package with local and gateway
server/UI/CLI exports, config schemas, transcript parsing, model
detection, and package metadata.
- Registered `hermes_local` and `hermes_gateway` as built-in adapters
across shared constants, server registries, CLI packaging, and UI
adapter registries.
- Kept the external adapter override path compatible so installed Hermes
packages can shadow built-ins and restore the built-in parser when
disabled.
- Added Hermes gateway onboarding docs, board-operator docs, Docker
smoke assets, and shell smoke harnesses for join/e2e validation.
- Added scoped task-bridge API-key support, authorization checks,
issue-origin handling, and tests for Hermes-created Paperclip tasks.
- Hardened gateway transport and redaction behavior for API keys,
headers, session data, and smoke diagnostics.
- Updated release packaging/bootstrap checks for the Hermes packages
while leaving `pnpm-lock.yaml` out of the PR per repository policy.
## Verification
Targeted local verification recorded before PR handoff:
- `pnpm --filter @paperclipai/hermes-paperclip-adapter exec vitest run
src/gateway/server/execute.test.ts` — 14/14 passed.
- `pnpm test:hermes-gateway-smoke` — 6/6 passed.
- Hermes package typecheck/build checks passed.
- Focused server/UI adapter tests passed — 31/31.
- Release helper Node tests passed — 18/18.
- `git diff --check origin/master..HEAD` passed.
Fresh Docker E2E smoke evidence:
- Ran `pnpm smoke:hermes-gateway-e2e` on 2026-06-26 with a fresh state
directory and fresh Docker container against a live Paperclip dev
server.
- Hermes direct execution reached `completed`.
- Hermes stop/cancel path reached `cancelled`.
- Hermes gateway created a Paperclip task, Paperclip ran the Hermes
agent, and the task reached `done` with the expected marker response.
- Temporary board auth keys, token files, smoke state, and Docker
containers were cleaned up after the run.
PR checks on head `b5eae40ce`:
- GitHub Actions passed: `policy`, `review`, `Typecheck + Release
Registry`, all general test shards, all serialized server shards,
`Build`, `Canary Dry Run`, `e2e`, and aggregate `verify`.
- External checks passed: Snyk and Socket Project Report.
- External Socket Pull Request Alerts remained pending after the
first-party CI matrix completed.
## Risks
- Medium risk: this spans adapter registration, package publishing,
gateway execution, onboarding docs, API-key scoping, and UI adapter
metadata.
- Migration risk is low: the scope-config migration adds a nullable
column and does not rewrite existing keys.
- Gateway execution depends on operator-provided Hermes API
configuration; the smoke covers the Docker gateway path but real
deployments may differ by network/auth setup.
- Direct Greptile review on the latest expanded diff is file-count
limited, although the commitperclip review gate passed.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies.
> - Heartbeat runs are the control-plane record of each agent execution
window.
> - Long-running local agents can exhaust context or stop while still
holding useful next-step state.
> - Operators need that stop reason, next action, and continuation path
to be durable and visible.
> - This pull request adds run liveness metadata, continuation
summaries, and UI surfaces for issue run ledgers.
> - The benefit is that interrupted or long-running work can resume with
clearer context instead of losing the agent's last useful handoff.
## What Changed
- Added heartbeat-run liveness fields, continuation attempt tracking,
and an idempotent `0058` migration.
- Added server services and tests for run liveness, continuation
summaries, stop metadata, and activity backfill.
- Wired local and HTTP adapters to surface continuation/liveness context
through shared adapter utilities.
- Added shared constants, validators, and heartbeat types for liveness
continuation state.
- Added issue-detail UI surfaces for continuation handoffs and the run
ledger, with component tests.
- Updated agent runtime docs, heartbeat protocol docs, prompt guidance,
onboarding assets, and skills instructions to explain continuation
behavior.
- Addressed Greptile feedback by scoping document evidence by run,
excluding system continuation-summary documents from liveness evidence,
importing shared liveness types, surfacing hidden ledger run counts,
documenting bounded retry behavior, and moving run-ledger liveness
backfill off the request path.

- Remote PR checks on head `e53b1a1d`: `verify`, `e2e`, `policy`, and
Snyk all passed.
- Confirmed `public-gh/master` is an ancestor of this branch after
fetching `public-gh master`.
- Confirmed `pnpm-lock.yaml` is not included in the branch diff.
- Confirmed migration `0058_wealthy_starbolt.sql` is ordered after
`0057` and uses `IF NOT EXISTS` guards for repeat application.
- Greptile inline review threads are resolved.
## Risks
- Medium risk: this touches heartbeat execution, liveness recovery,
activity rendering, issue routes, shared contracts, docs, and UI.
- Migration risk is mitigated by additive columns/indexes and idempotent
guards.
- Run-ledger liveness backfill is now asynchronous, so the first ledger
response can briefly show historical missing liveness until the
background backfill completes.
- UI screenshot coverage is not included in this packaging pass;
validation is currently through focused component tests.

Re-align phase1 with upstream: hermes_local ships via hermes-paperclip-adapter on the server and UI (hermes-local module). Fixes ERR_PNPM_OUTDATED_LOCKFILE from server/package.json missing a dep still present in the lockfile.
Add shared BUILTIN_ADAPTER_TYPES and skip external plugin registration when it would override a built-in type. Docs list Hermes as built-in; Droid remains the primary external example.
Made-with: Cursor
- Plugin loader: install/reload/remove/reinstall external adapters
from npm packages or local directories
- Plugin store persisted at ~/.paperclip/adapter-plugins.json
- Self-healing UI parser resolution with version caching
- UI: Adapter Manager page, dynamic loader, display registry
with humanized names for unknown adapter types
- Dev watch: exclude adapter-plugins dir from tsx watcher
to prevent mid-request server restarts during reinstall
- All consumer fallbacks use getAdapterLabel() for consistent display
- AdapterTypeDropdown uses controlled open state for proper close behavior
- Remove hermes-local from built-in UI (externalized to plugin)
- Add docs for external adapters and UI parser contract
- SPEC: reflect that Paperclip now manages task-linked documents and
attachments (issue documents, file attachments) instead of claiming
it does not manage work artifacts
- agents-runtime: remove bootstrapPromptTemplate from recommended config,
add deprecation notice, update minimal setup checklist

- Restored docs/ directory that was accidentally deleted by `git add -A`
in the v0.2.3 release script
- Replaced generic "P" favicon with actual paperclip icon using brand
primary color (#2563EB)
- Added light/dark logo SVGs for Mintlify navbar (paperclip icon + wordmark)
- Updated docs.json with logo configuration for dark/light mode
- Fixed release.sh to stage only release-related files instead of `git add -A`
to prevent sweeping unrelated changes into release commits
