 ## Modules
 
-- `reaper_bridge` — READ-ONLY bank consumer: receives bank snapshots from the extension and exposes them as a read-only view. **Never writes to the extension's bank** — this is a load-bearing invariant; no mutation path exists in this module. It owns TWO prefix-guarded ext-state write entry points, `writeUsageExtState` (`rsusage_`) and `writeBakeExtState` (`rsbake_`), each refusing every other key; neither weakens the read-only-*bank* invariant, because neither payload is bank state and `banks`/`view`/`tail`/`assign` stay structurally unwritable. It also owns the bake crossing — `extensionActionAvailable` / `invokeExtensionAction` (`NamedCommandLookup` + `Main_OnCommandEx` against `getReaperParent(3)`, the instance's OWN project tab, never the focused one) and `projectTempoBpm`.
+- `reaper_bridge` — READ-ONLY bank consumer: receives bank snapshots from the extension and exposes them as a read-only view. **Never writes to the extension's bank** — this is a load-bearing invariant; no mutation path exists in this module. It owns TWO prefix-guarded ext-state write entry points, `writeUsageExtState` (`rsusage_`) and `writeBakeExtState` (`rsbake_`), each refusing every other key; neither weakens the read-only-*bank* invariant, because neither payload is bank state and `banks`/`view`/`tail`/`assign` stay structurally unwritable. It also owns the bake crossing — `extensionActionAvailable` / `invokeExtensionAction` (`NamedCommandLookup` + `Main_OnCommandEx` with `getReaperParent(3)`, the instance's OWN project tab, as `proj` — a request, not a DAW-verified guarantee; see the header) and `projectTempoBpm`.
 - `reasampler_processor` (`shell/instrument/`: `reasampler_processor.cpp` lifecycle + `process()`, `processor_state.cpp` component-state I/O + UI-thread parameter accessors, `processor_reload.cpp` the off-audio-thread `reloadInstrument`/publish family — Q-W2v, T4-12 split; `process()` and its per-block work stay ONE TU on purpose, no cross-TU call on the per-sample path) — VST3 `SingleComponentEffect` shell: declares event-input bus + **permanently stereo** output (GA fix: dynamic mono↔stereo bus renegotiation deleted; `ChannelMode` is now decode-only), marshals MIDI note-on/off into the VoiceEngine, renders audio; owns off-audio-thread `reloadInstrument` + atomic pointer swap so `process()` does no allocation, no file I/O, no bridge calls. The instance state is `{loaded capture id, one InstrumentParams}`, and `reloadInstrument` resolves + decodes exactly that one capture into the `SampleData` the engine plays. **Self-contained playback (pS):** `ComponentState` v10 adds a `SampleRefs` table — per referenced sample, a project-relative path + decode intrinsics (root, loop, channels, displayName); `reloadInstrument` decodes directly from `SampleRefs`, bank-free (plays with the extension absent). The bank/bridge is a browser source: loading a capture copies its reference in; the reopen-heal timer + poll-to-play apparatus are removed. `retireIdleDrain()` retires fully-idle drain snapshots on the UI-timer cadence. Voice-param edits (`setVoiceCount`/`setVoiceMode`/`setMonoTrigger`) rebuild the engine from the already-decoded `SampleData` via the drain-slot swap — no bank re-read, no WAV re-decode, no audible cut to ringing tails. **FB1:** applies the post-mixer `masterGainLinear` (from `ComponentState` v8) as a per-sample ramp over the summed output — no zipper noise. **GA v9:** `channelModeExplicit_` flag persisted; `channelModeFor()` auto-defaults the mode from the loaded capture's channel count when the flag is not set. **pS:** `ComponentState` bumped v9→v10 (`SampleRefs` table); pre-v10 blobs lift to empty refs and re-save self-contained. **pS-usage:** publishes instance usage (held `SampleRefs` paths) to `rsusage_<instanceGuid>` at the tail of `reloadInstrument` (off audio thread) via `reaper_bridge::writeUsageExtState`; `ComponentState` bumped v10→**v11** (`instanceGuid` field); pre-v11 blobs mint guid on first publish.
 - `reasampler_editor` — VST3 `IPlugView` LICE editor shell: hosts a LICE-drawn child window; the Sample face is home and Browse is a modal picker over it. Split on the Sample face's BAND axis, mirroring the pure `sample_bands` allocator: `editor_session` (session/bridge state, caches, commit-and-reload), `editor_controls` (the ONE `faceLayout` band resolve every paint and hit-test path shares, the node-drag bounds, the value labels, and the per-instance controls the parameter set does not carry — the parameter-set binding itself is the pure `core/instrument/ui/deck_values` module this only adapts int ids onto), `editor_models` (the orthogonal half: which stored struct each transient editor selection names — the staged-envelope pack/unpack, the drawn contour, and the three velocity curves), then matching paint and input sets — `editor_paint`/`editor_input` (dispatch + drag router + hover dispatch), `_chrome`, `_waveform`, `_deck` — plus the two band-independent surfaces (`_browse` for the modal picker, `_curve` for the velocity-curve popup) and `editor_platform` (IPlugView/Win32 window plumbing). Shared internals in `editor_internal.h`, no TU of its own. Drop-onto-editor ingest is NOT shipped (deferred).
 - `reasampler_embed` — implements `IReaperUIEmbedInterface` so the instrument draws inline in the TCP/MCP without a plugin-owned HWND; delegates layout to `embed_strip`. A read-only readout: the loaded capture across the keyboard span with its root marked, plus the activity level. It takes no mouse input (there is nothing on the strip to select).
