ULIDs are lexicographically sortable by creation time, making log
directories and run lists naturally ordered without extra metadata.

Make RunConfig.run_id required (String instead of Option<String>) so the
caller always provides the ID. This eliminates the duplicate UUID that
was generated: one in the HTTP server / CLI and a second inside the
engine fallback.
Also fixes a bug in preamble.rs where context key "run_id" was read but
the engine stores it as "internal.run_id", so the run ID always showed
as "unknown" in preambles.
Renames PipelineStarted.id to PipelineStarted.run_id for consistency.

Add git observability to match Kilroy parity: base_sha, run_branch,
worktree_dir on PipelineStarted; GitCheckpoint events with commit SHAs;
final_git_commit_sha on PipelineCompleted/PipelineFailed; run_branch in
manifest.json; final_git_commit_sha in final.json; diff.patch per node;
and git::diff_against helper.

Create a dedicated git branch + worktree per pipeline run (Local env only)
and commit after every node checkpoint. This gives each run an isolated
working directory and a full git trail of changes per stage.
New module: git.rs with ensure_clean, head_sha, create_branch,
add/remove_worktree, and checkpoint_commit (using arc identity).
Engine changes: RunConfig gains run_id and work_dir fields; after each
checkpoint save, a git commit is created in the worktree and the SHA
is stored in checkpoint.git_commit_sha.
CLI changes: for Local execution, the repo cleanliness is verified
before any log files are written, then a worktree is created on branch
arc/run/{uuid}, cwd is switched into it, and cleanup runs after the
engine completes.
Handler changes: run_hook() accepts work_dir so hooks execute in the
worktree.

All three providers use the OpenAI Chat Completions protocol via
OpenAiCompatibleAdapter:
- Kimi (KIMI_API_KEY) → api.moonshot.ai/v1
- Z.AI (ZAI_API_KEY) → api.z.ai/api/coding/paas/v4
- Minimax (MINIMAX_API_KEY) → api.minimax.io/v1
Key changes:
- Extend Provider enum with Kimi, Zai, Minimax variants
- Add with_name() to AnthropicAdapter for non-Anthropic providers
using the Messages protocol (conditional Bearer vs x-api-key auth)
- Add complete_via_stream() for providers requiring stream=true
- Add with_provider() to AnthropicProfile and OpenAiProfile so the
session routes requests to the correct adapter
- Add kimi-k2.5, glm-4.7, minimax-m2.5 to model catalog
- Handle reasoning_content in OpenAI compatible adapter (capture in
stream, store as ContentPart::Thinking, echo back in assistant
messages) — required by Kimi for multi-turn tool use
- Handle missing [DONE] sentinel in SSE streams (Minimax omits it)
- Wire up all exhaustive Provider matches across agent and attractor

Replace scattered provider string literals ("anthropic", "openai", "gemini")
with a Provider enum and ModelId struct in the llm crate. This prevents
bugs like routing an OpenAI model to Anthropic's API (the bug fixed in
3263d0c) by making the provider identity a compile-time checked value.
Key changes:
- Add Provider enum (Anthropic, OpenAi, Gemini) with as_str/Display/FromStr
- Add ModelId struct bundling Provider + model name
- Replace WebFetchSummarizer's separate model+provider fields with ModelId
- Replace BaseProfile.id: &'static str with BaseProfile.provider: Provider
- Replace ProviderProfile::id() -> &str with provider() -> Provider
- Parse --provider CLI strings to Provider early via FromStr
- Update AgentBackend and CliBackend to use Provider instead of String/Option
Serialization boundaries (Request.provider, Response.provider, Client HashMap
keys) remain as strings, converted via provider.as_str().

The WebFetchSummarizer was sending requests without specifying a
provider, so they always routed to the default (Anthropic). When using
the OpenAI or Gemini profile, the summarizer model (e.g. gpt-4o-mini)
was rejected by Anthropic with a 404.
Add a `provider` field to WebFetchSummarizer so the summarization
request routes to the correct provider. Also improve the error message
to include the model name, and relax the parity test assertion to
accept summarized content.

The 8 params are all distinct concerns freshly extracted from Session;

Move the tool execution subsystem (~250 lines) into a dedicated module:
- execute_tool_calls: dispatches to parallel or sequential execution
- execute_and_emit_one_tool: wraps execution with event emission
- execute_one_tool: registry lookup, validation, and execution
- validate_tool_args: JSON schema validation for tool arguments
- truncate_tool_result: output truncation for history storage
These functions have zero dependency on Session's history, state machine,
or LLM interaction. Session now calls the extracted free functions,
passing needed context as parameters.

Bundle the execution parameters (env, cancel) into a single
ToolContext struct, reducing the ToolExecutor closure signature
from 3 parameters to 2. This makes the type alias simpler and
means future parameters won't change the signature.
Key changes:
- Add ToolContext { env, cancel } in tool_registry.rs
- Update ToolExecutor type alias: Fn(Value, ToolContext) -> ...
- Update all tool factories in tools.rs, v4a_patch.rs,
subagent.rs, mcp_integration.rs, and skills.rs
- Update all call sites in session.rs and tool_execution.rs
- Update test helpers and test call sites

ReadBeforeWriteEnvironment had 9 pass-through methods that just forwarded
to self.inner. The new delegate_execution_env! macro generates these
automatically, so only the 4 customized methods (read_file, write_file,
delete_file, grep) need to be written explicitly.

Remove the standalone `reasoning: Option<String>` field from
Turn::Assistant. Reasoning/thinking text is now stored exclusively
in `provider_parts` as `ContentPart::Thinking` blocks, eliminating
the dual-storage reconciliation logic in `convert_to_messages`.
Add `Turn::reasoning_text() -> Option<&str>` accessor that extracts
the first non-redacted thinking text from provider_parts.

All three provider profiles (Anthropic, OpenAI, Gemini) independently
registered the same 7 core tools (read_file, write_file, shell, grep,
glob, web_search, web_fetch). Extract a shared register_core_tools()
function in tools.rs that accepts a ToolRegistry, SessionConfig (for
shell timeout customization), and optional WebFetchSummarizer.
Each profile now calls register_core_tools() then adds its
profile-specific tools:
- Anthropic: edit_file (with 120s shell timeout via config)
- OpenAI: apply_patch (default 10s shell timeout)
- Gemini: edit_file, read_many_files, list_dir (default 10s shell timeout)

The parser, applicator, types, and tool factory had no dependency on the
OpenAI profile. Moving them to `v4a_patch.rs` makes them independently
testable, reusable by other profiles, and cuts `openai.rs` nearly in half.

New `mcp` crate using rmcp v0.15.0 with stdio and HTTP transports.
MCP tools are registered as regular `RegisteredTool` instances in the
agent's `ToolRegistry`, sharing the same `execute_one_tool` path as
built-in tools. Tools are namespaced as `mcp__{server}__{tool}`.
Includes end-to-end test: real MCP server subprocess (Python echo
server) → mock LLM issues tool call → MCP bridge executes → result
flows back through the session loop.

After compaction, the agent previously lost awareness of which files it
touched. This adds a FileTracker that records file operations from tool
calls (read_file, write_file, edit_file, apply_patch) and injects a
## File Operations section into the structured compaction prompt so file
context survives across compaction cycles.
- FileTracker: BTreeMap-based tracker with record_from_tool_calls()
- Structured compaction prompt with Goal/Progress/Key Decisions/
Failed Approaches/Open Issues/Next Steps sections
- tracked_file_count field on CompactionCompleted event
- File tracker accumulates monotonically (never reset)

web_fetch now converts HTML responses to clean markdown using the htmd
crate (stripping script/style tags), and supports an optional prompt
parameter that makes a secondary LLM call to answer questions about the
fetched content. Each provider profile picks a cheap/fast summarizer
model (Haiku, gpt-4o-mini, gemini-2.0-flash).

Enables machine-readable output from the agent CLI by streaming
SessionEvent objects as newline-delimited JSON to stdout. This
unlocks scripting, integration testing, and UI integration.
- Make SessionEvent serializable with ISO-8601 timestamps via chrono
- Add OutputFormat enum (text/json) and --output-format CLI flag
- JSON mode: each event is one JSON line to stdout, flushed per line
- JSON mode: skip print_output/print_summary (all info in event stream)
- Text mode (default): behavior unchanged
