car-server-core 0.52.0

//! Built-in coding agent ("CAR Coder").
//!
//! The user states an intent; the coder turns it into a **verifiable outcome
//! contract** (shell commands that must pass), gets it confirmed, then works in
//! a throwaway **git worktree** until every check is green — natively (CAR
//! inference + policy-gated tools) or by delegating to an installed external
//! CLI (Claude Code, Codex, Gemini), with CAR re-running the contract either
//! way. Results are published as a `car/coder/<id>` branch in the user's repo;
//! the user's checkout is never touched.
//!
//! ## Module map
//!
//! - [`contract`] — `OutcomeContract` derivation (inference, repair loop) and
//!   evaluation (runs checks through the policy-gated shell tool)
//! - [`session`] — session state machine, event stream (`CoderEvent`), JSON
//!   snapshots under `~/.car/coder/`
//! - [`shell_tool`] — `WorktreeExecutor`: file tools + a host `shell` tool,
//!   all rooted/clamped at the worktree and gated by the inspector chain
//! - [`policy`] — the coder inspector set (no pushes, no privilege escalation,
//!   no writes outside the worktree, …)
//! - [`native_loop`] — the plan→edit→verify→repair loop driving CAR inference
//! - [`router`] — engine selection between the native loop and external CLIs
//! - [`merge`] — squash-commit the worktree and deliver it: a local branch,
//!   a managed project's `main`, or (headless) an append-only push plus one
//!   reconciled pull request
//! - [`discuss`] — repo-grounded, strictly READ-ONLY conversation that can be
//!   distilled into a run intent (`coder.discuss.*`); it never starts a session
//! - [`fix_issues`] — files a dogfooding round's durable-fix proposals as
//!   issues on the (public) releases tracker: the *reporting* half of
//!   self-correction
//! - [`provenance`] — trust tiers for tracker text: every issue resolves to
//!   `runtime` / `maintainer` / `public` from its author account before its
//!   text is readable at all, and a `public` body can neither seed a session
//!   nor source an outcome contract. Live today for deduplication; the session
//!   and contract gates are the types the future tracker consumer must use
//!
//! ## Security boundary (read this before extending)
//!
//! The shell tool executes on the **host** with the daemon's privileges and
//! (deliberately) the real toolchain + network. The inspector chain blocks the
//! known-dangerous verbs (git push, sudo, destructive ops outside the
//! worktree, credential reads) plus every route that would *publish* the work
//! around the merge gate — the forge CLIs (`gh`, `glab`, `hub`) are cut to a
//! read-only allowlist and the registry publish subcommands (`npm publish`,
//! `cargo publish`, `docker push`) are denied — and the executor pins the
//! working directory to the worktree. But this is policy hardening, **not a
//! sandbox**: a model determined to misbehave can, e.g., pipe curl to sh
//! inside the worktree, or reach `gh` through a wrapper script.
//! The hard stops are the contract confirmation gate before any work starts
//! and the merge approval gate before anything reaches the user's repo.
//!
//! Anything that reads a tracker adds a second boundary: the report target is
//! **public**, so an issue body is attacker-controlled text. [`provenance`]
//! resolves every issue to a trust tier from its author account — never from
//! anything in the body — and its types are the reason a caller cannot read
//! tracker text without one.
