* feat(gitops): resolve branch, tag, and SHA refs to immutable commits before fetch The ref model now resolves a configured branch, tag, or full commit SHA to an immutable commit before any content is downloaded, and records both the configured and the resolved identity where revision state persists. - RefKind (branch | tag | sha) is a resolved property, not caller-asserted. A bare string resolves branch-first, then tag; a full 40/64-hex SHA self-resolves with no remote round-trip. Branch and tag both fetch via a bare --branch name; a SHA uses init + shallow fetch + detached checkout. - A single ls-remote with narrow heads/tags refspecs pins the configured ref to an immutable SHA; rev-parse HEAD must equal the resolved SHA or the fetch refuses (tip-changed) instead of materializing unreviewed content. - Error union grew: REF_NOT_FOUND (ref-neutral, replaces BRANCH_NOT_FOUND), UNSUPPORTED_REF (a pinned SHA the host will not serve), and a service-level REF_DELETED upgrade that fires when a classified REF_NOT_FOUND occurs for a source with prior fetch history (a vanished ref reads as delete/force-push, not a fresh typo). Status mapping: REF_NOT_FOUND/REF_DELETED to 404, UNSUPPORTED_REF to 400. - Configured-vs-resolved identity is recorded via a nullable resolved_ref_kind column on gitops_generations (added to CREATE TABLE and re-added for legacy installs through maybeAddCol). The kind is deliberately NOT in the plan fingerprint: two sources naming the same commit differently are the same plan. Docs updated (git-sources feature page, connect-a-git-source tutorial, and the native-git-transport internal deep-dive) to the ref-neutral naming. * fix(gitops): harden ref resolution after pre-merge audit Request peeled annotated-tag refs from ls-remote, detect force-pushes and ref-kind changes against prior fetch identity, persist resolved kind on application rows, and add real-git tag/SHA integration coverage plus ref-neutral UI and operator docs. * test(gitops): mock verifyFastForward in direct producer suite The producer tests stub the transport seam but were missing resolved kind on resolveRef and a verifyFastForward stub, so second pulls tripped the new ref-continuity checks as REF_DELETED. * test(git): remove unused buildBareFixtureRepo helper Fixes backend lint failure after the integration fixture was refactored to buildRichFixtureRepo without dropping the old wrapper. * fix(gitops): correct fast-forward ancestry verification under size bounds Replace the dual shallow-fetch ancestry probe with a single-tip deepen strategy, keep verifier Git work inside the transport watchdog, and add real-Git regression coverage for linear advances and rewritten history. * fix(gitops): bound fast-forward verification with exponential deepen Replace per-commit deepen loops with exponential steps, cap remote fetch rounds, and share one deadline across verifier Git calls. Budget exhaustion now surfaces as a classified timeout instead of REF_DELETED. * fix(gitops): classify fast-forward probe failures accurately Normalize verifier probe timeouts and unexpected exit codes into transport failures, interpret merge-base status 1 as proven non-ancestry only, and treat shallow stagnation as timeout instead of REF_DELETED. * fix(gitops): satisfy tsc on probeFailure never returns * fix(gitops): address Phase E QA findings on ref verification Remove the fast-forward scratch repo after verification so pull size caps are not inflated, classify GitHub not-our-ref as UNSUPPORTED_REF, persist fetched_resolved_ref_kind on create-from-git, and broaden REF_DELETED copy for retagged tags.
