- 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)

The pattern of filtering Error-severity diagnostics, collecting messages,
and returning ArcError::Validation appeared in three places. Extract it
into validation::raise_on_errors and use prepare_from_file in run_from_branch.

Recursively compares serialized ServerConfig keys against the
OpenAPI ServerConfiguration schema properties. Also fixes 7 fields
that were missing from the spec: log, checkpoint, git.slug,
git.author, git.webhooks, sandbox.exe, sandbox.env.

FileInliningTransform was treated as a "custom" transform that every
caller had to remember to register manually. This caused arc validate
to break and left latent bugs in run_from_branch and SubWorkflowHandler.
Add prepare_with_file_inlining() and prepare_from_file() to WorkflowBuilder
so file inlining is a built-in concern. Rename prepare_workflow to
prepare_from_source for clarity. Fix the SubWorkflowHandler to use
prepare_from_file when reading from stack.child_dotfile paths.

Replace the RunCompare envelope (checkpoints + files + stats) with a
standard PaginatedRunFileList response containing FileDiff items,
matching the existing pagination pattern used by other endpoints.

following the cancel endpoint conventions, with paused RunStatus variant,
demo stubs, and regenerated TypeScript client.

Register FileInliningTransform in validate_command so @file references
(e.g. @prompts/simplify.md) are resolved during validation, matching
the behavior in run.rs.

- Reuse jwt_auth::decode_pem_env in read_github_private_key instead of duplicating base64/PEM logic
- Extract delivery_id once at top of webhook_handler instead of 3 separate times
- Remove redundant funnel_port field from WebhookManager (derive from listener.port())
- Gate parse_event_metadata behind debug log level to avoid full JSON parse on every webhook

Adds a webhook subsystem that receives GitHub App webhooks when configured
in server.toml with [git.webhooks] strategy = "tailscale_funnel". On startup,
it binds a local HTTP listener on a random port, exposes it via `tailscale funnel`,
and patches the GitHub App webhook URL. Incoming webhooks are verified with
HMAC-SHA256 before processing.

Bake the imagegen script into a Daytona snapshot so the agent

Rust 1.94.0 introduced new clippy lints and rustls now rejects X.509 v1
certificates. This fixes all three CI jobs:
- Format: cargo fmt across the workspace
- Clippy: unnecessary_unwrap, useless_format, derivable_impls,
type_complexity, too_many_arguments, redundant_closure, map_or
simplification, and other new lints
- Tests: generate v3 certs (with extensions) for mTLS tests so newer
rustls accepts them

The Run: line was using raw eprintln! without indentation or dimming,
making it visually inconsistent with the Logs: and Sandbox: lines.

Tests were failing locally because the Daytona sandbox needs GitHub App credentials to clone a private repository, but the exec tests were passing . This updates the tests to load the credentials and supply them during initialization.
A stalled Anthropic SSE stream caused a run to hang for 10 minutes
until the stall watchdog killed it. The HTTP connection succeeded but
no SSE events arrived, and with stream_read_timeout defaulting to None
the read blocked indefinitely.
- Set AdapterTimeout default stream_read to 300s (5 min), matching
the idle timeout used by OpenAI Codex
- Increase BackoffConfig default initial_delay_ms from 200ms to 5s
so transient LLM failures get meaningful recovery time before retry

Adds two new tests to the Daytona integration suite:
1. `daytona_exec_command_cancelled`: verifies that an active token cancellation properly aborts a running command and yields a correct exit code/message.
2. `daytona_exec_command_local_timeout`: tests the recent fix that prevents commands from hanging indefinitely by enforcing a local timeout fallback.
The Daytona SDK HTTP client can sometimes hang indefinitely if the connection
drops or the server stops responding. Since `daytona_sandbox.rs` was awaiting
the `execute_command` call directly, this could cause the entire workflow engine
to stall, eventually triggering the stall watchdog.
This wraps the `execute_command` call in a `tokio::select!` block, enforcing
the requested `timeout_ms` locally (with a 5s grace period) and respecting
the `cancel_token`.

- Forward-order hunk application with cursor tracking (fixes duplicate line matching)
- Accept `@@ context` without trailing ` @@` (backward compat preserved)
- Stacked `@@` anchors collapse to single hunk using last context
- `*** End of File` marker for backward search from end of file
- `*** Move to:` for file renames during update
- 4-pass fuzzy matching: exact → trim_end → trim → unicode normalization
- Heredoc wrapper stripping (<<EOF / <<'EOF' / <<"EOF")
- Update system prompt to use canonical `@@ context` format
