Merge Risk: 🔵 Low · up to The installer adds exact-ref suite pinning while keeping rolling installs as the default. Current concerns are bounded: pinned installs still refresh unrelated local tag state, and documented handling of inherited detached checkouts could permit an incorrect prebuilt suite to be reused; the change is mergeable with explicit owner follow-up.

Plan the addition of a `--ref` flag to `whitaker-installer`, allowing the lint suite to be installed at a specific commit SHA or tag while keeping the rolling release as the default. The plan covers CLI plumbing, git helpers for detached checkout and default-branch recovery, prebuilt SHA matching, dry-run output, tests, and documentation. Pre-implementation; no code changes yet.
Introduce an optional `git_ref` field on `InstallArgs`, exposed as `--ref <REF>`, so a user can name a commit SHA or tag to pin the lint suite to. The flag defaults to `None`, preserving the rolling default, and is accepted both bare and under the `install` subcommand. Record the Stage A findings (abbreviated manifest git SHA, default-branch discovery command) in the execution plan.
Add four repository operations, all routed through the existing timeout-guarded git helper: `resolve_commit` peels a commit-ish to a full SHA, `fetch_ref` retrieves a ref and its tags from origin, `checkout_detached` pins the working tree to a commit, and `ensure_default_branch` reattaches a detached clone to the branch named by `origin/HEAD` so a later pull succeeds. Cover them with tests exercising real git repositories in temporary directories.
Extend `ensure_workspace` to accept an optional ref and return a `WorkspaceCheckout` carrying the workspace root and the resolved pinned commit. When a ref is given, the managed clone is resolved (fetching once on a miss) and checked out as a detached HEAD; pinning is refused for a current-directory workspace via a new `RefUnsupported` error. The update path now reattaches a detached clone to its default branch before pulling, so a previous pin cannot break a later un-pinned install. The installer confirms the pin to the user.
Add `expected_git_sha` to `PrebuiltConfig` and validate it in the download pipeline: because the rolling manifest records an abbreviated SHA, a pinned install reuses the prebuilt artefact only when the resolved full commit begins with the manifest's SHA, otherwise it falls back to a source build. Thread the resolved pin from the workspace checkout through the fast-path and prebuilt contexts. Cover the match, mismatch, and un-pinned cases with unit tests and a behaviour scenario.
Add the pinned ref to `DryRunInfo` so `--dry-run --ref` reports the pin, and emit a "Pinning Whitaker suite to REF..." progress line before the checkout. Cover the dry-run rendering with unit tests and add CLI behaviour scenarios for a pinned dry-run and for refusing `--ref` inside a Whitaker workspace.

Cover the managed-clone lock with a competing pinned clone and unpinned update, proving that the waiter re-evaluates the shared checkout after it acquires the lock. Assert pinned commit provenance reaches prebuilt validation and that a SHA mismatch stops before archive download. Restore the no-default-feature build regression while removing its unused implementation stub, and update the developer and execution-plan records.

Use the repository-approved filesystem abstractions.
Replace std::path::PathBuf with camino and perform the manifest read through cap_std or cap_std::fs_utf8. Reuse an existing repository helper when available.
As per coding guidelines: use cap_std, cap_std::fs_utf8, or camino instead of std::fs and std::path for filesystem access.

Summary
This pull request implements the explicit-pin part of issue #271: a new
--ref <SHA|tag>flag forwhitaker-installerthat builds and stages thelint suite from an exact commit of
leynos/whitaker, so a consumingrepository can hold its lint behaviour steady rather than tracking the moving
default branch.
Rolling remains the deliberate default: running the installer with no
--refbehaves byte-for-byte as before (rolling prebuilt download, default-branch
source fallback). The version-matched default proposed in the issue was
rejected in review, because it would force a fresh installer release for every
suite update; that remainder is intentionally not implemented. This addresses
part of #271, and with the explicit-pin capability shipped and the
version-matched default declined, the issue can be closed.
Design notes:
--refaccepts any commit-ish; tags and SHAs are reproducible pins, branchnames are not (documented).
--refis refused when the current directory is itself a Whitakerworkspace, to avoid mutating the user's own working tree.
--refcomposes with--no-update: the ref is resolved against theexisting clone and fetched only on a resolve-miss.
