Warn when a ticket resolved against a stored (production) graph points at a
definition that was renamed or moved in the current code.
- core diffRenames(from, to): pairs a definition gone by identity (name+file)
with a same-body-signature definition that is new in the newer graph. Signature
= structural fingerprint + normalized rendered text + props + rendered-children,
stable across a rename/move. Confident 1:1 only; generic/ambiguous bodies
skipped (no false renames).
- core SHA-keyed store: saveGraphToStore/loadGraphFromStore/graphStoreDir ->
.coderadar/graphs/<sha>.json (or "working") + a latest pointer.
- buildBundle gains a currentGraph option -> "version skew — matched `X`;
renamed `Y` (file) in the current graph".
- CLI: scan --store writes the store; bundle --against <sha|latest> loads the
current graph for the diff.
- Fixture pair g3-version-skew/{old,new} (InvoiceCard.tsx -> BillingCard.tsx,
renamed and moved). .coderadar/ gitignored.
7 core + 4 store + 2 parser-react + 3 agent-sdk tests; verified end-to-end via
the CLI. eval 317/0/0/0, determinism 1.000, all metrics 1.000; typecheck + lint
clean.

Phase 6.4 — Version skew & rename tracking (failure modes G3, A11)
An agent often resolves a ticket against a stored graph (the commit in production) while the code has moved on. If the matched definition was renamed or moved on main, the match points at a file that no longer exists under that identity. This step detects that and warns with the new name/path.
Changes
diffRenames(fromGraph, toGraph)(core): pairs a definition gone by identity (name+file) in the newer graph with a same-body-signature definition that is new there. Signature = structural fingerprint + normalized rendered text + props + rendered-children — all stable across a rename or file move. Confident 1:1 only: unique among both the gone and arrived sets; generic empty bodies and ambiguous many-to-many sets are skipped (no false renames).storage):saveGraphToStore/loadGraphFromStore/graphStoreDir→.coderadar/graphs/<sha>.json(orworkingoutside git) + alatestpointer.buildBundlegains acurrentGraphoption →version skew — matched \InvoiceCard` (…); renamed `BillingCard` (…) in the current graph`.scan --storewrites the store;bundle --against <sha|latest>loads the current graph from it for the diff.Fixture & tests
