+## Milestone 7 — capture action family
+**Goal:** Bindable capture actions for master / selected tracks / selected items /
+razor area, each with wet-dry + tail options. CONTEXT.md §actions, Build order 7.
+**Verify (in DAW):** Each action registered (bindable in Actions list), routes to
+the offline backend, and honors wet/dry + tail. **Load-bearing principle:** none
+auto-inserts into the arrange.
+
+- [x] Source resolvers: master mix, selected tracks, selected items, razor area
+  (`GetSet_LoopTimeRange`, `P_RAZOREDITS`, `CountSelectedMediaItems`, etc.).
+- [x] Register each as a bindable action (`command_id`/`gaccel`/`hookcommand`).
+- [x] Wet-dry + tail options per action.
+- [x] Review gate: confirm no capture path touches the timeline.
+
+**Notes/decisions:**
+- Four **wet** bindable capture actions — master mix, selected tracks, selected items, razor area — registered under the `CEREBELLUM_REASAMPLER_CAPTURE_*` command-id prefix. Each routes to `OfflineRenderBackend` (RENDER_* snapshot/restore, dither/normalize off, 32-bit float), produces a `Sample`, adds it to the bank, persists, and calls `MarkProjectDirty`. The M3 spike action was retired.
+- **Wet-only decision (Daniel):** REAPER offline render has no true pre-FX "dry" bit — the only wet/dry-adjacent lever (`&8192` pre-fader stems) is post-FX. Approximate-dry action variants were removed rather than ship a "dry" that isn't. `CaptureRequest.wetDry` is retained as the seam for true dry (M10).
+- Pure `render_settings` module maps source mode → RENDER_SETTINGS bits and parses `P_RAZOREDITS` (union of track-audio areas), unit-tested. No capture path inserts into the arrange (load-bearing gate); non-destructive (selection/razor read-only).

+**Note (from M7):** The null test requires a TRUE pre-FX dry capture, which REAPER offline render cannot produce via RENDER_SETTINGS (there is no pre-FX bit). True dry must be obtained by bypassing the source FX around an offline render (snapshot→bypass→render→restore) OR via the M8 realtime pre-FX path — so the dry-capture mechanism should be designed as part of the M10 null-test work.
