Ξ-W2-T1: the resample bake chain — instrument renders, extension banks, one click re-points and resets

 - `bank_model` — `Sample` metadata struct + `BankIndex` (add/remove/query/tier/dedup-by-hash + JSON round-trip). Test it hard — it is the heart.
 - `bank_book` — multi-bank registry: an ordered set of banks each wrapping a `BankIndex`. **Pool privileges (un-deletable/un-renamable/un-evacuable, never zero banks) enforced in-model.** Owns create/rename/reorder/delete of named banks, active-bank id, and index-only move/copy/remove of a sample between banks. The JSON round-trip lives in the sibling `bank_book_json` TU (Q-W5 split; serialize/deserialize via a private static `nameKey` seam) — one model, one codec, same public surface.
 - `slot_map` (`core/model`) — the gap-preserving display-position carrier for ONE bank (sample id → slot, ≥0), extracted from `bank_book` (Q-W1): append/remove/reorder (insert-before-and-shift)/`reconcile` against live membership, `resetDense` migration seed, JSON round-trip. Wrapped (not merged) by `bank_book`.
+- `resample_name` — the display name a resample's new bank entry takes, so repeated bakes
+  read as one iteration chain (`Kick` -> `Kick r2` -> `Kick r3`) rather than as N unrelated
+  captures. Presentation only: the machine-readable lineage is the ledger's
+  `parentSampleId`, and nothing parses this name back into one.
 - `provenance` — capture-recipe fingerprint: build/encode/compare a `rsprov1` fingerprint of scope, range, tail, rate/channels, track GUIDs, and FX-chain identity. **A thin reproducibility fingerprint — NOT a serialized chain to restore.** It is the recipe facet of the tracking system whose authority lives in `core/tracking`; the lineage facet (which file derives from which) is the ledger's, not the `Sample`'s.
