New node: HashVaultLabelBuilder (🏷️ Hash Vault Label Builder).
Concatenates up to 4 any-type inputs with a configurable separator into
one STRING for Hash Vault Save's label input. Wire once per workflow
(e.g. style + variant + intensity from Gemini Style Transfer Settings)
and never type a label manually again.
Empty strings, None, and whitespace-only inputs are skipped so partial
wiring produces clean output. Non-string inputs are stringified at join
time.
Solves the repeated-typing pain exposed by running the 77-entry
photographer QA pass. Labels follow the canonical
"Photographer / Variant / intensity" convention automatically.
HashVaultSave now writes {hash_key}.json (label, timestamps, payload summary) and {hash_key}.thumb.png (256px preview) alongside the .pt, inside the existing FileLock. New optional label input on Save node, does not factor into the hash. DeterministicHashVault bumps last_accessed_at on cache hit (silent no-op for pre-v1.3.0 entries). folder_paths import is tolerant of being outside ComfyUI so the sidecar helpers are reusable from tooling.
tools/migrate_hash_vault.py backfills sidecars for pre-v1.3.0 entries, using file mtime as created_at and "(legacy)" as label.

Dropped the forceInput=True on payload_string so the socket is truly
optional. Added any_input_2, any_input_3, any_input_4 alongside the
existing any_input. Users can now hash purely on image + converted-
widget values without manufacturing a synthetic payload string.
Primary use case: image-only APIs with meaningful widgets. For a
Gemini Style Transfer node with (image, style dropdown, strength
float) and no prompt, convert the style and strength widgets to
inputs, then wire image -> any_input, style -> any_input_2,
strength -> any_input_3. All three factor into the hash.
Back-compat: workflows that only use payload_string + any_input
produce bit-identical hash keys to v1.0/v1.1. The "__slotN:" prefix
only appears when slots 2-4 are actually wired, so existing
hash_vault/ entries keep hitting. Verified with a direct comparison
against the pre-v1.2 hashing path.
