Struct CheckoutFingerprint 

pub struct CheckoutFingerprint {
    pub head: String,
    pub status: String,
    pub git_config: String,
    pub git_hooks: String,
    pub git_refs: String,
    pub index_flags: String,
    pub info_exclude: String,
}

HEAD + git status --porcelain of a checkout at one instant — the identity a read-only validator session must preserve byte-for-byte.

Fields

head: String

git rev-parse HEAD.

status: String

git status --porcelain --untracked-files=all: index + worktree status of tracked files plus EVERY untracked non-ignored path; ignored paths (target/, .kranz runtime) never appear.

git_config: String

Contents of <git-common-dir>/config: core.fsmonitor, core.hooksPath, aliases, and external-diff drivers all execute during the ENGINE’s own git invocations — a validator that can write only .git/config owns the host without touching the worktree.

git_hooks: String

Sorted name HASH lines for non-.sample files in <git-common-dir>/hooks — a planted hook executes on the engine’s next git operation that isn’t hooks-disabled.

git_refs: String

git for-each-ref output: moving a ref retargets later merges without touching HEAD or the worktree.

index_flags: String

git ls-files -v output: skip-worktree/assume-unchanged flags hide worktree modifications from git status (4th-pass review) — the flags are part of the identity, so setting one is drift.

info_exclude: String

Contents of <git-common-dir>/info/exclude: the local exclude file hides untracked files from git status without touching the tree.

Implementations

impl CheckoutFingerprint

pub fn capture(repo: &GitRepo) -> Result<Self>

Capture the identity of repo’s checkout right now.

All git invocations run on a VERIFICATION handle (hooks + fsmonitor disabled): a poisoned core.fsmonitor in the checkout’s config must never get its payload executed by the detection itself (4th-pass review — detection previously ran git status before comparing config, so the payload ran first). The .git metadata itself is read via the filesystem with BOUNDED, no-follow reads (5th-pass: a replaced config or info/exclude that is a FIFO or an unbounded source must not hang or exhaust the engine mid-detection — anything unusual reads as a stable refusal marker, which is itself drift).

pub fn drift(&self, after: &Self) -> Option<CheckoutDrift>

The drift between self (before the session) and after — None when the checkout is byte-identical.
