 - `wire` (`core/wire`) — the ONE length-prefixed ext-state wire codec (Q-W1): `putField`/`parseUnsignedDecimal` + the bounds-checked `Cursor` (`field`/`fieldInt`/`fieldInt64`/`fieldSizeT`/`fieldDouble`), replacing four near-identical copies (`provenance` / `assignment_request` / `sample_usage` / `bank_sync`). `core/wire/bytes.h` is the sibling little-endian byte codec (`putLE`, `ByteReader`, `doubleToBits`/`bitsToDouble`) that `component_state_io` is the biggest consumer of. `core/wire/ext_state_read.h` owns the `GetProjExtState` grow-loop retry policy (Absent/Complete/Overflow) shared by `persist`, `usage_scan`, and `reaper_bridge`. `core/wire/reasampler_uid.h` (the FOREVER-FROZEN VST3 class-UID macros) also lives in this directory.
 - `reasampler_uid.h` — SDK-free header owning the FOREVER-FROZEN VST3 class-UID integer macros (stable + beta pairs, `REASAMPLER_PROC_UID_*` / `REASAMPLER_PROC_UID_BETA_*`) and the `REASAMPLER_ACTIVE_UID_*` channel-selector macros. Split out of `reasampler_vst.h` so the pure extension side (`instrument_drop`) can derive the `.vstpreset` class-ID hex string without pulling in the VST3 SDK. Both `reasampler_vst.h` (runtime `FUID`) and `instrument_drop` (preset hex string) source from this single header — the binary identity and the preset-file identity cannot diverge.
 - `assignment_request` — pure ingest-assign wire: typed request record carrying the drop payload from the `ingest` shell through to the VST3 bridge.
+- `bake_wire` — the resample bake's request/outcome pair on ONE per-instance key (`rsbake_<guid>`): the instrument writes a `BakeRequest`, invokes the extension's action synchronously, and reads the extension's `BakeOutcome` back over the same key inside that one call. Not a handshake — a call and a return, and it must not grow a claim protocol. Also the ONE home of the bake action's command-id suffix and of the leading underscore `NamedCommandLookup` needs but `rec->Register("command_id", …)` does not, so both artifacts name one action. `BakeStatus` values are WIRE INTEGERS: never renumber, only append, and an unrecognized value decodes as `Failed` rather than as the numeric default `Ok`.
 - `instrument_drop` — pure FX-drop payload builder: constructs a Steinberg-format `.vstpreset` image (channel-active class ID + the instrument's own component state, capture pre-selected) the shell applies via `TrackFX_SetPreset`; owns the `infoNamesFxHotspot` prefix classifier for `GetThingFromPoint` tokens. All-or-nothing contract — caller rolls back via `TrackFX_Delete` on any failure.
 - `sample_usage` — instance-usage wire: `UsageRecord`, `planUsagePublish` (fresh/heal/clean-replace/union/remint publish plan), `foldUsageRecords`/`usageHeldPaths` (liveness fold — protect-all when records exist but no instance is live; abort→protect-all on unreadable record; `counted` carries key-attributed live records), `identityMatches` (ReaSampler 9000 FX identity). REAPER-free, unit-tested. The mirror of `assignment_request` on the instrument→extension direction: the wire format and the two safety-critical decisions (what to write on publish, which records count at prune time) are pure so they are provable without a DAW. It lives here because it is a *wire format* with an instrument-side writer; the fold's output is consumed by `core/tracking`'s authority, which owns every consumer-facing decision built on it.
