Deleting a refinement key was non-atomic. A key's state spans <key>.json plus
sidecars (<key>.value_fn.pt, <key>.sampler_ctx.json, attn_maps/blessed maps +
K/V banks + creativity latent + velocity store), and there was no delete route —
users removed the visible <key>.json by hand, orphaning the rest. The orphans are
still applied: _v2_ascend_conditioning loads <key>.value_fn.pt purely by name
(not gated on the json), and blessed K/V inject at a 0.04 floor even at reward 0.
So a "cleared" key kept steering future generations, surviving both a ComfyUI
restart and the manual delete — the persistent half of the long-run quality drift
(the per-session half was the hook leak in the previous commit).
- templates.py: delete_refinement_key() sweeps the canonical json + every <key>.*
sidecar + clear_refinement_data (attn_maps banks, velocity disk+memory).
absolute_store_info()/clear_absolute_store() for the keyless Absolute taste store
(__funpack_absolute_global__): it learns from every rated gen across all prompts,
is invisible in the key list, and was otherwise only wiped by Session Reset.
Routes: POST refinement_keys/delete, GET/POST refinement_keys/absolute|clear_absolute.
- Refinement Key Loader node: "Delete Key" + "Clear Global Taste" buttons.
- Movie Editor: api deleteRefinementKey/absoluteStoreInfo/clearAbsoluteStore +
FunPack menu "Delete refinement key…" / "Clear global taste store…".
- tests: atomic-delete sweep + empty-key guard (real store, unique key, cleanup).
Pre-existing 16 failures unchanged (stale mocks); +2 new passing.

The key name is now the filename: a key "123" is refinements/123.json, listed by
stem and resolved directly by name everywhere (Studio, loader, Editor, sampler).
This fixes shortcuts spawning ghost keys — a dropped/loaded <key>.json is found
by the refiner's own path lookup with no scanning or adoption needed. Sidecars
keep a <key>.<mode> suffix (value function, sampler context, latents); only keys
that aren't a valid filename fall back to the old <prefix>_<md5> hash.
Clean break: legacy hashed files are not migrated (and are hidden from the key
list rather than shown as hash names). Exports now download as <key>.json so a
re-dropped export is already canonical — no tolerant filename/inner-field
reconciliation layer needed.
Import now prompts overwrite-or-cancel on a name collision (409 -> confirm ->
retry with overwrite), in both the Editor and the Refinement Key Loader node.
413 chunked upload (Vast.ai / Runpod proxy body caps) retained.
