Native reftable development need not wait for Byron's planned in-memory reference support in `gix-ref`. Gate integration on that external prerequisite so the adapter follows an agreed interface rather than a speculative design.

Superseded by draft PR #3011 for the code-only baseline;
reftablesremains the effort mainline.A test-only Git oracle gives future native reftable work concrete compatibility expectations without coupling it to
gix-refpolicy; see #2798. This draft covers the incremental plan, Git-generated fixtures, and checks of equivalent archived loose, packed, and reftable baselines, including references, reflogs, and relocated common/private worktree records.gix-reftableremains a placeholder with no native storage API or runtime dependencies.gix-refis unchanged and absent from the crate's dependency graph, including test configuration.PreviousValue, namespace policy, and dereferencedHEADupdate contracts are deferred to Task 4'sgix-refintegration.cargo test --offline --locked -p gix-reftable --test reftablepasses all four tests with bothGIX_TEST_FIXTURE_HASH=sha1andGIX_TEST_FIXTURE_HASH=sha256. Both variants are wired intojust unit-tests, and those focused nextest commands pass too. Targeted Clippy passes with-D warnings; focusedrustfmtand diff-hygiene checks also pass. Full workspace and cross-platform CI have not been run locally.Opened by GitHub Copilot (GPT-6) on request.
