Local worktree sandbox runs never pushed the arc/run/{run_id} branch to
GitHub, causing PR creation to fail with a 422 "head invalid" error.
Remote sandbox runs already push during checkpoint, so this only fires
for GitCheckpointMode::Host.

Shows "Base: main (260a391e5b4c)" after the Worktree line in the run
header, helping users identify the starting point. Uses worktree base
SHA when available, falls back to remote base SHA for remote-only runs.

Extract `embed_token_in_url` and `resolve_authenticated_url` helpers
into arc-github to eliminate duplicated credential resolution + URL
authentication logic across ExeSandbox, DaytonaSandbox, and engine.rs.

Move GitHub App authentication (types, JWT signing, token creation,
credential resolution) into a new leaf crate `arc-github`. ExeSandbox
now owns `github_app` directly and resolves clone credentials on-demand,
eliminating the GitCredentialSandbox decorator and its wrapping code in
cli/run.rs. GitCloneParams simplified to a single clean `url` field.

- WorktreeSandbox: add missing delegations for is_remote(),
ssh_access_command(), and origin_url() to avoid silently returning
defaults instead of delegating to inner sandbox
- GitCredentialSandbox: replace manual shell quoting with shlex::try_quote
per project shell_quote() convention
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add is_remote(), ssh_access_command(), and origin_url() to the Sandbox
trait so run.rs can use trait methods instead of matching on
SandboxProvider post-construction. This removes daytona_sandbox_ref and
exe_sandbox_ref, eliminating 11 provider-checking sites that reached
through Arc<dyn Sandbox> to make provider-specific decisions.

- Extract `load_sandbox()` helper to deduplicate cp_command's Download/Upload arms
- Use `shlex::try_quote` in handler/command.rs shell_quote (was using less safe manual quoting)
- Call `self.resolve_path()` in ExeSandbox::upload_file_from_local instead of inlining
- Create parent dirs in download_recursive for nested files
- Use async `entry.file_type().await` instead of blocking `is_dir()` in upload_recursive
- Add missing parent directory creation in DaytonaSandbox::upload_file_from_local
- Rename `_worktree_path` to `worktree_path` (variable is used, underscore was misleading)

Allow customizing when git worktrees are created via a new `worktree_mode`
enum (always/clean/dirty/never) in `[sandbox.local]`. Previously, worktree
creation was hardcoded to only occur on clean repos.

- E2e tests for local, Docker, and Daytona sandbox backends
- Make cp::reconnect pub for integration test access
- Stop deleting worktrees after run completion so arc cp can
access local/Docker sandbox files (prune step to come later)
- Rustfmt cleanups

Introduces sandbox reconnection via persisted SandboxRecord, adds
upload_file_from_local to the Sandbox trait, and migrates arc-sprites
shell quoting to shlex::try_quote.

- Add `image` property to OpenAPI `ExeConfiguration` schema so the
generated TS client gets a typed interface instead of bare `object`
- Extract `resolve_exe_clone_params()` helper and wire it into preflight
so `--preflight --sandbox exe` tests the git clone path
- Expand `run_from_branch()` to support exe.dev: resolve sandbox provider,
connect SSH, initialize VM, fetch+checkout the run branch, wrap with
GitCredentialSandbox + ReadBeforeWriteSandbox, and clean up on exit

Replace ad-hoc replace('\'', "'\\''") escaping and unquoted interpolation
with a shell_quote() helper backed by shlex::try_quote to prevent command
injection via branch names, clone URLs, image names, env vars, file paths,
and grep patterns. Covers both arc-exe (SSH transport) and arc-workflows
(Daytona sandbox).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add image field to ExeConfig so users can specify a Docker image for
exe.dev VMs via TOML config. Pass run_id to ExeSandbox for VM-to-run
correlation in sandbox_info(). Wire resolved exe config into the
preflight path for consistency with the main execution path.

- Replace fragile shell escaping in exec_command with base64 encoding
(matching Daytona's wrap_bash_command pattern)
- Add ssh_command() to ExeSandbox and wire --ssh flag support in run.rs
- Move git cloning into ExeSandbox::initialize() via GitCloneParams,
removing clone_repo_into_exe() from run.rs

Subagent lines (▸ subagent[...], ✓ subagent[...]) now render at 8-space
indent instead of 6, visually distinguishing them as children of the stage.

- Wire up cancel_token in ExeSandbox::exec_command via tokio::select!
- Clone the local git repo into exe.dev VMs after initialization
- Add GitCredentialSandbox decorator for push credential refresh
- Enable GitCheckpointMode::Remote for exe.dev (rename daytona_* → remote_*)
- Rename setup_daytona_git → setup_remote_git (already sandbox-agnostic)

Replace `.filter(..).next_back()` with `.rfind(..)` to satisfy the

Allow setting pull_request.enabled in ~/.arc/cli.toml so auto-PR

The old code called child.wait() before draining stdout/stderr pipes.
If the child wrote more than the OS pipe buffer, write() blocked while
the parent blocked on wait() — classic deadlock. Now we spawn concurrent
tasks to drain the pipes before waiting.

The opt-in change (7400a9d5) left these two tests with empty asset_globs,
which now means "no asset collection". Add the matching glob so the tests
actually exercise asset collection.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Asset collection previously ran a full `find` scan before and after every
stage (~30s per scan), even when no assets were needed. This makes it
opt-in: only workflows with an `[assets] include = [...]` section in their
TOML config will run asset collection, and only with user-specified globs.
- Add AssetsConfig struct and wire through WorkflowRunConfig, RunDefaults,
and RunConfig
- Remove baseline snapshot approach; single post-execution scan using
user globs filtered by mtime and size budgets
- Delete hardcoded pattern constants, is_asset_candidate, matches_simple_glob,
FileFingerprint, and snapshot() — replaced by configurable globs
- Skip all asset work when asset_globs is empty (zero overhead default)

The full failure message (including entire stdout/stderr) was shown inline,
making terminal output very noisy. Now only the last non-empty line is
displayed, truncated to 120 chars. The full error remains in the log file.

Embeds the ULID run_id directly in the directory name so logs dirs
can be easily correlated with runs.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
CommandHandler was using tokio::process::Command to execute scripts
directly on the host machine, completely bypassing the configured
sandbox (local, Daytona, Docker). This meant script nodes in workflows
ran on the host while agent nodes ran in the sandbox, causing fix cycles
where agents edited files in the sandbox but lint checks ran on the host.
Now delegates to services.sandbox.exec_command() so all node types
execute in the same environment.

The ReadBeforeWriteSandbox was blocking engine writes to /tmp/arc-commit-msg
on the second git checkpoint because the file already existed from the first
checkpoint. Temp files don't need source-file protection.

- Add GitCheckpointFailed variant to WorkflowRunEvent with node_id and error fields
- Add trace() arm at ERROR level per logging strategy (operation cannot continue)
- Add rename_fields rule to default node_label from node_id
- Emit the event before returning ArcError::Engine on checkpoint failure
- Update events-strategy.md with the new event in the checkpoints table
- Add rename_fields serialization test

The git checkpoint functions (host and remote) now return Result<String, String>
with descriptive error messages instead of Option<String>. When a checkpoint commit
fails, the engine returns ArcError::Engine with FailureClass::Deterministic,
stopping the run immediately. This prevents stuck cycles where an agent's edits
are silently lost between node transitions.

The server was emitting Anthropic-style SSE events (content_block_delta,
message_delta, etc.) but both consumers — the arc_server provider and
run_prompt_via_server CLI — expect `event: stream_event` with serialized
StreamEvent JSON payloads. This caused streaming to silently produce no
output in server mode.
Now forwards all StreamEvent variants directly (text, tool calls,
reasoning, etc.) instead of manually mapping a subset.

Generate the run ULID early and display it before the logs directory,
then pass it into setup_worktree and setup_daytona_git instead of each

Five new CLI-level tests covering file creation, shell execution,
read-only permission enforcement, JSON output format, and read+edit
multi-step tool use. All gated with #[ignore = "requires API key"].

Tests the full production path: execute_and_emit_one_tool → real tool executor
→ ReadBeforeWriteSandbox guard, covering write-blocked, read-then-write,
grep-then-write, edit-blocked, and new-file-allowed scenarios.
Also updates MutableMockSandbox::grep to do substring matching against
in-memory files so the grep integration test works end-to-end.

The Claude CLI native binary install was getting OOM-killed (exit 137)
in the default 1 GiB sandbox. Using the daytona-medium default snapshot
also pre-includes Node, making the prereq install step a no-op.

Codex CLI no longer reads OPENAI_API_KEY from the environment at
runtime. It requires `codex login --with-api-key` to store credentials
via its auth system. Add a login step after ensure_cli for codex.
Also pass API keys via exec_command's env_vars parameter as belt-and-
suspenders alongside the env file, to avoid fs-to-process race conditions
in the Daytona sandbox.

- Use `cat file | command` instead of `command < file` for stdin piping
to avoid redirect issues in nested shell wrappers
- Include both stdout and stderr in error messages when CLI exits non-zero
(previously only showed stderr, hiding API errors in stdout)
- Install Node 20 via nodesource + bash/curl as prerequisites for CLI tests
- Use bash instead of sh for Claude CLI install script
The codex test still fails with 401 Unauthorized — the OPENAI_API_KEY
env var isn't reaching the codex process in the sandbox despite the env
file being sourced correctly (gemini works with the same mechanism).

- Pass GitHub App credentials in create_env() and daytona_snapshot_sandbox
so private repo clones succeed
- Install git in sandbox before running git CLI in clone_private_repo test
- Use brynary/arc (where app is installed) instead of rust-lang/rust for
clone_public_repo_gets_credentials test
- Fix git_checkpoint_remote_emits_events assertion: expect 1 event (work
node only) since start is skipped and exit breaks before checkpoint
- Install Node 20 via nodesource and bash/curl in CLI test prerequisites
- Use bash instead of sh for Claude CLI install script
- Shorten toolbox_idle_diagnostic sleep durations to finish in ~12s
- Add nextest config with 120s per-test timeout

Provider implicit caching (Gemini, OpenAI) is non-deterministic — cache
hits can occur on some turns but not others. Checking only the final turn
caused intermittent failures. Track the best cache ratio across all turns
instead, which still validates the adapter surfaces cached token counts.

- Anthropic max_tokens: use model catalog limit instead of hardcoded 65536,
fixing claude-sonnet-4-5 (max_output=64000) API errors
- OCI feature tgz: detect actual filename from registry instead of
assuming devcontainer-feature.tgz (registries use suffixed names)
- Test LlmCodergenBackend: implement one_shot() for prompt handler support
- Quarantine all Inception/mercury-2 parity matrix tests (unreliable provider)
