Replace `gh auth token` with GitHub App IATs scoped to `contents: read` for
Daytona sandbox git cloning. Public repos are auto-detected and cloned without
credentials. Private repos get short-lived, repo-scoped tokens. Clear error
messages for each failure mode (app not installed, suspended, no repo access,
auth failure). Falls back gracefully when no GitHub App is configured.

Add both models with aliases (gpt54, gpt54-pro). Neither replaces
gpt-5.2 as the OpenAI default. Update fallback chain test since
GPT-5.4 ($2.50) is now closer to Opus ($15) than GPT-5.2 ($1.75).

Per-node `max_visits` now overrides the graph-level `max_node_visits`
(and the dry-run default of 10) for individual nodes, giving tighter
control over specific loops like fix-and-verify cycles.

Allows literal $ signs in prompts and DOT files by writing $$. Also
refactors VariableExpansionTransform to use expand_vars instead of
string replace, fixing a substring-matching bug with $goal.

Revert the graphviz language identifier back to dot (Shiki doesn't
bundle either) and register a custom TextMate grammar via Mintlify's
styling.codeblocks.languages.custom config. The grammar (extracted from
apps/arc-web/app/data/dot-grammar.ts) highlights keywords, shape names,
attributes, strings, comments, and operators.

Changes ```dot to ```graphviz across all docs for better syntax highlighting
in Mintlify (Shiki). Full digraph blocks get a title derived from the workflow
name (e.g. title="hello.dot").

- Add follow_up, steering_before_input, and steering_mid_task parity tests
- Add steering_queue_handle() to Session for test access
- Expand provider_tests! macro to cover all 7 providers (Kimi, Zai, Minimax, Inception)
- Update model names to match current catalog (gpt-5-mini, gemini-3-flash-preview, etc.)
- Fix OpenAI-compatible tool result serialization: emit one ChatMessage per ToolResult
instead of bundling all results into a single message with only the first tool_call_id.
This was causing Kimi to reject requests during parallel tool calls.

Implements a complete Slack integration for the interviewer system using
Socket Mode (WebSocket-based, no public URL required). Supports all five
question types: YesNo, Confirmation, MultipleChoice, MultiSelect, and
Freeform (via thread replies with @mention).

Replace flat Vec<Clause> parser with AST-based recursive descent parser
supporting full operator precedence (&& binds tighter than ||, ! is prefix).
New operators: >, <, >=, <= (numeric), contains (substring/array membership),
matches (regex, validated at parse time). Simplify ConditionSyntaxRule to
delegate entirely to parse_condition(). Public API unchanged.

The pattern Some("agent") | Some("agent_loop") | Some("prompt") |
Some("one_shot") was duplicated across preamble.rs (3x) and
validation/rules.rs (1x). Centralizes into a single function in
graph/types.rs. Also fixes stale doc comment on default_registry.

Keep legacy aliases (agent_loop, one_shot) in the handler registry
and validation rules for backwards compatibility. Add codergen_mode
attribute support in the DOT parser, translating legacy values to
the new type names.

- Rename handler type strings: codergen → agent_loop, wait.human → human,
script → command, wait.timer → wait
- Rename handler modules/structs to match: AgentHandler, HumanHandler,
CommandHandler, WaitHandler
- Split one_shot into PromptHandler (handler/prompt.rs) with shape=tab mapping
- Remove CodergenMode enum and codergen_mode attribute — one_shot is now its
own handler type, not a mode flag on the agent loop handler
- Update all demo DOT files: codergen_mode="one_shot" → shape=tab
- Update spec, README, validation rules, preamble, and hook tests

Each major feature gets its own H2 heading with narrative depth

- Extract shared prompt/agent hook setup (model resolution, system prompt,
user message, timeout wrapper) into reusable helpers
- Fix blocking I/O: std::process::Command → tokio::process::Command for
host-mode hook execution
- Cache reqwest::Client per TLS mode via OnceLock instead of rebuilding
per HTTP hook call
- Return Cow from resolved_hook_type() to avoid cloning HookType on
every call
- Rename command_executor → executor in HookRunner

- Change HookExecutor trait to take Arc<dyn Sandbox> so agent hooks can
share the sandbox with the ToolRegistry via ToolContext
- Replace hand-rolled 2-tool dispatch with register_core_tools() giving
agent hooks the full tool set (read_file, write_file, shell, grep, glob)
- Add strip_code_fences() to handle LLMs wrapping JSON in markdown
- Set max_tokens(1024) on prompt hooks to avoid exceeding model limits
- Add e2e tests: TOML parsing, prompt proceed/block, agent proceed,
agent with tool use (reads a file via read_file tool)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Prompt hooks make a single-turn LLM call returning {"ok": true/false}.
Agent hooks run a multi-turn LLM tool loop with sandbox access (exec_command, read_file).
Both fail-open on errors/timeouts. Prompt hooks default to 30s timeout,
agent hooks to 60s with max 50 tool rounds. Default model is "haiku".

Introduce a `tls` field on HTTP hooks with three modes: `verify` (default,
requires https + cert validation), `no_verify` (requires https, skips cert
validation), and `off` (allows http, skips cert validation). This prevents
hooks from accidentally sending credentials over plaintext connections.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
HTTP hooks (type = "http") now actually execute instead of failing with
"no command specified". The executor POSTs the hook context as JSON,
parses HookDecision from the response, and fails open on errors.
Header values support $VAR/${VAR} interpolation gated by an
allowed_env_vars whitelist on the hook definition. Renames
CommandHookExecutor to HookExecutorImpl since it now handles both
command and HTTP hook types.

- Replace JSON-based HookEvent::Display with simple match arms
- Use floor_char_boundary for Unicode-safe truncation in effective_name
- Cache compiled regexes in HookRunner instead of recompiling per check
- Simplify run_non_blocking (was run_parallel) to plain sequential loop
- Propagate hook_runner through parallel handler branch services
- Use unique temp file paths for sandbox hook context (avoid collisions)
- Add hook imports to engine.rs, reducing verbose crate:🪝: paths
- Extract duplicate RunFailed hook code into run_failed_hook helper

Introduce a configurable hook system that triggers user-defined actions
at workflow lifecycle points (RunStart, StageStart, StageComplete,
StageFailed, EdgeSelected, CheckpointSaved, etc). Hooks can block
execution, skip nodes, or override edge routing via JSON decisions.
- New `hook/` module: types, config, executor (command), runner
- Engine instrumented at 8 lifecycle points with HookRunner calls
- TOML config: `[[hooks]]` in server.toml and run config files
- Config cascade: server hooks + run hooks merge, name collisions
resolved by run config winning
- Remove legacy tool_hooks.pre/post from codergen handler (breaking)
- 30 e2e integration tests covering all hook events and behaviors
