Replace DOT source code view with rendered SVG visualization using
viz.js. Running stages pulse with a teal glow animation, completed
stages are tinted green, and the graph supports pan/zoom/direction
controls matching the workflow diagram page.

Parallel branches now get isolated git worktrees so concurrent file
writes don't collide. Works across Local, Docker (bind-mount), and
Daytona (remote exec_command) environments.
Key changes:
- git.rs: add create_branch_at() and merge_ff_only() helpers
- engine.rs: add GitState struct, remote worktree helpers
(git_create_branch_at_remote, git_add_worktree_remote, etc.)
- handler/mod.rs: add git_state field to EngineServices (RwLock)
- handler/parallel.rs: WorktreeEnv wrapper, per-branch worktree
setup/teardown, checkpoint commits per branch, ff-merge winner
before returning to engine
- handler/fan_in.rs: ff-merge to winner's HEAD, set best_head_sha
- E2E tests for Host (local) and Daytona (remote) modes
When git_state is None, behavior is unchanged.

Prevents truncation of large tool calls (e.g. write_file with big

Convert insights route to a parent layout with sidebar and two children:
- index route (insights-editor) with the existing SQL editor
- /insights/new with LLM input, template cards, and SQL link
Also fix wide layout detection in app-shell to check all matched routes
instead of only the last match.

LLM-authored output can set failure_class to non-canonical strings like
"retryable", "transient", or "permanent". Expand FromStr to accept 30+
aliases with case-insensitive trimmed matching, matching Kilroy's
normalizedFailureClass(). Unknown values fail-closed to Deterministic
instead of returning Err.

Absolute `cd` paths in shell commands (script/tool_command attributes) silently

Add 8 missing transient_infra patterns (crates.io registry, toolchain,
cross-device link errors), 2 structural hints (write_scope_violation
variants), and reorder heuristic priority to check transient_infra
before budget_exhausted to match Kilroy's classification behavior.

Raise the Anthropic adapter fallback from 4096 to 16384 to prevent
truncation of large tool call JSON when the model isn't in the catalog.
Add max_tokens as a configurable DOT node attribute that flows through
SessionConfig to LLM requests, following the same pattern as
reasoning_effort. Priority: node attribute > catalog > provider default.
Ported from kilroy (danshapiro/kilroy) commits 99a5cd7 and 78fadad.

Replace simple CI dot indicators with rich check status data model
(CheckRun[] with per-check name, status, duration). Cards in Verify
and Merge columns show a full-width expandable status row with summary
icon and text. Clicking reveals individual check results. Pending
column cards now display the human-in-the-loop question above the
Answer Question button.

Extract hint patterns into const arrays (TRANSIENT_INFRA_HINTS,
BUDGET_EXHAUSTED_HINTS, STRUCTURAL_HINTS) and add 28 new patterns
from Kilroy to prevent transient/budget failures from misclassifying
as deterministic. Add comprehensive regression test per pattern plus
count-guard tests to catch accidental additions/removals.

Move HTTP server (Axum routes, JWT auth, serve CLI command, server
config) from arc-workflows into a dedicated arc-api crate. This
improves separation — arc-workflows is a pipeline engine library,
not a web server.
- Create crates/arc-api with server.rs, jwt_auth.rs, serve.rs,
server_config.rs and their integration tests
- Remove server feature flag and optional deps from arc-workflows
- Update arc-cli to depend on arc-api for ServeArgs and serve_command

Runs: add a view toggle (columns vs list) with collapsible

- Change GitCheckpointMode::Remote to Remote(PathBuf) so both variants
carry a repo path for MetadataStore shadow commits
- Unify init_run and shadow write logic to work with either Host or
Remote mode, eliminating Host-only gates
- Add trailers (Arc-Run, Arc-Completed, Arc-Checkpoint) to remote
checkpoint commits via write_file + git commit -F to avoid shell
escaping issues with multi-line messages
- Wire up meta_branch for Daytona in run.rs (was only set for worktree)
- Fix sandbox name collisions by adding random hex suffix
- Fix pre-existing build_router() test compilation errors from JWT auth
- Add E2E tests for Host shadow branch and Daytona shadow branch

Add a bare_string parser that accepts values containing hyphens and
dots like gpt-5.2-codex-spark and gemini-3-flash-preview. These are
common in kilroy DOT files for model names but were previously rejected
by arc's strict identifier parser.
All 14 kilroy DOT files now parse successfully.

Ed25519 asymmetric JWT: arc-web signs with private key, arc-attractor verifies
with public key. Adds AuthenticatedService axum extractor to all routes, jose
dependency for TypeScript signing, and key generation script.
Startup behavior: ARC_JWT_PUBLIC_KEY set → enforce JWT auth; not set +
ARC_INSECURE_DISABLE_AUTHENTICATION=true → allow unauthenticated; neither →
refuse to start with clear error.

Copy 14 DOT workflow files from the kilroy project and add tests proving
arc can parse them. 11 files parse successfully, exercising features
including subgraphs, fan-out/fan-in, conditional routing, goal gates,
model stylesheets, and large 40+ node workflows.
3 batch test files (batch_*.dot) document a parser gap: arc requires
quoted values for strings with hyphens/dots (e.g., "gpt-5.2") while
kilroy's parser accepts them unquoted.

Aligns with the kilroy implementation of the Attractor spec. A default

- Add Provider::ALL constant for iterating all variants in tests
- Add catalog guardrail tests: every provider has models, provider strings
round-trip, as_str round-trips through from_str
- Add arc-agent guardrail tests: every default_model exists in catalog,
profile context_window matches catalog for default models
- Fix context window drift: profiles now look up catalog instead of
hardcoding sizes, with conservative fallbacks for unknown models
- Add #[serde(deny_unknown_fields)] to config structs so typos like
[lmm] instead of [llm] produce parse errors
- Extract DEFAULT_BASE_URL constant in OpenAI adapter

- all_conditional_edges (ERROR): fires when a node has outgoing edges but
all are conditional with no unconditional fallback, preventing silent
fall-through to arbitrary edge selection.
- orphan_custom_outcome (WARNING): fires when outcome-based routing lacks
an unconditional fallback edge, catching typos in outcome values.
- Enhanced condition_syntax rule to also validate via parse_condition(),
catching malformed expressions that pass static checks (e.g. empty key).
- Updated integration test graph to use unconditional fallback edge.

Spawn failures (binary not found) and timeouts are infrastructure issues,
not domain failures. Return them as Err(AttractorError::Handler(...)) so
the engine can distinguish them from script exit-code failures and
potentially retry.

Register Inception Labs' Mercury diffusion LLM as a new provider using

Three separate binaries are replaced by a single `arc` CLI with subcommands:
arc llm prompt/models, arc agent, arc run, arc validate, arc serve
Extract public CLI modules (arc_llm::cli, arc_agent::cli::AgentArgs/run_with_args)
so the new arc-cli crate can dispatch to each library. Integration tests migrate
to crates/arc-cli/tests/cli.rs.
