Batch capture + panel action buttons/labels landed; conform-on-insert
verified already shipped; resample-and-mute-source cut by Daniel
(Design View park/hide supersedes it). Drag-out remains in PLAN.

-The CMake project and binary are now named `reaper_reasampler`. This is **ReaSampler** — a per-project audio sample-bank capture tool. The MPE modules (`mpe_model`, `mpe_view`) have been removed. M0–M8 are complete (bank_model, peaks, capture offline+realtime, persist, bank_panel, insert, capture action family, RealtimeRecordBackend, tail T1+T2+T1-followons). Phase B multi-bank (B1–B5, B-cap), Phase D1/D2 Design View (D1–D5, D2-W1–W3-B), Phase V versioning/beta-channel (V1/V3, V4), M10 provenance + re-capture from source, and Phase R Reclaim (R1–R3: prune-reconcile core, dry-run shell, guarded deletion + action + panel button) have all landed. M9 slots and M11 polish remain. The *discipline* — pure REAPER-free testable core split from REAPER-facing shells — is **preserved** throughout.

 - `provenance` — capture-recipe fingerprint (M10): build/encode/compare a `rsprov1` length-prefixed fingerprint of scope, exact range, tail, rate/channels, track GUIDs, and order-sensitive FX-chain identity; parse/compare for drift detection on re-capture. A thin reproducibility fingerprint — NOT a serialized chain to restore. Drives `BankIndex::updateInPlace` / `BankBook::updateSampleInPlace` (order-preserving, id-stable) on re-capture.
 - `prune_reconcile` — Phase R pure prune core: `pruneOrphans(present, referenced, owned)` computes `(owned ∩ present) − referenced` (exact-string path match); `buildPruneReport` tallies count/bytes/display-capped file list; `pruneDeletePlan` produces the confirm-time staleness intersection (`confirmed ∩ freshOrphans`). REAPER-free, filesystem-free. The safety-critical "which files are orphans" decision — hard-tested here before any I/O exists. Also: `BankBook::referencedPaths()` additive const union query (all banks incl. pool, de-duped) added to `bank_book`.
 - `prune_button` — Phase R pure layout/hit-test for the `bank_panel` footer Prune button: `computePruneButton` (right-anchored, suppressed gracefully when footer is too narrow) + `hitTestPruneButton`. Mirror of `mode_switch` / `tab_strip`.
+- `batch_capture` — M11 pure batch-capture planner: maps a list of source ranges to ordinal capture units, drives per-unit capture via a shared `captureAndIndexOne` helper, and aggregates mixed results. No REAPER types at the boundary.
+- `action_buttons` — M11 pure action-button strip layout/hit-test: divides a strip rect into N action buttons, min-width overflow-hiding, label formatting with "(unbound)" fallback, `ActionButtonRect` struct. Mirror of `mode_switch` / `bank_grid`.
 
 **REAPER-facing shells:**
 - `capture` — `ICaptureBackend` interface; `OfflineRenderBackend` (deterministic default) and `RealtimeRecordBackend`. Input: `CaptureRequest`. Output: finished file + populated `Sample` handed to `bank_model`.
 - `insert` — placement via `InsertMedia`; conform-to-project-tempo is an explicit opt-in flag, never silent stretching.
-- `bank_panel` — docked LICE-drawn grid: thumbnails, audition, multi-select, keyboard navigation.
+- `bank_panel` — docked LICE-drawn grid: thumbnails, audition, multi-select, keyboard navigation; a 28px action-button strip (M11) between the split body and tail footer that fires capture/insert/re-capture actions via `NamedCommandLookup` + `Main_OnCommand` and shows live keybinding labels via `kbd_getTextFromCmd`.
 - `persist` — project ext state (`SetProjExtState` / `GetProjExtState`, namespace `"reasampler"`) ↔ `BankBook` JSON (`"banks"` key) + `ViewModeModel` JSON (`"view_state"` key) + `TailSetting` JSON (`"tail_setting"` key) + `OwnedManifest` JSON (`"owned_files"` key) + writing-version stamp (`"version"` key, written via `stampVersion()` on every `saveToActiveProject()`); project-relative path resolution. A `projectconfig` hook (`BeginLoadProjectState(isUndo)`) triggers a deferred session reload on undo/redo so Ctrl-Z/redo visibly restores book/view/tail/manifest in-session. Hosts `ReaSamplerSession::pruneDryRun()` (read-only orphan enumeration via M4 project-relative resolution) and `pruneOrphanSet()` (full-set query for the R3 delete path); supplies `referencedPaths()` + `owned().paths()` to the `prune_reconcile` pure core.
 - `view` — Design View shell: reads the folder tree via `view_tree`, snapshots flag values before parking, drives hide + CPU-park on inactive-mode leaves (`B_SHOWINTCP`/`B_SHOWINMIXER`/`B_MAINSEND`/`I_FXEN` + per-FX offline) and derived visibility on parents; restores from snapshot. Never touches master or `B_MUTE`/`I_SOLO`.
 - `track_guid` — shared `MediaTrack*` → canonical GUID-string formatter; single source of truth for membership keys used by both the view shell and the actions layer.

+- [x] **Batch capture** (`batch_capture` pure module + `CAPTURE_BATCH_ITEMS` /

+  aggregation; actions fire one bank sample per selected item / per razor area;
+  transient per-unit selection with RAII restore; per-unit invariants + provenance;
+  single persist per batch; one summary line. `RunCapture` internals extracted to a

+- [x] **Action trigger buttons + keybinding help labels** (`action_buttons` pure
+  module + bank_panel strip): strip layout/hit-test with min-width overflow-hiding
+  and label formatting with "(unbound)" fallback; struct `ActionButtonRect`; a 28px

+  source via `NamedCommandLookup` + `Main_OnCommand`; labels show live bindings via
+  `kbd_getTextFromCmd`. Coexists with Phase R's prune button (footer). New CTest
+  target `action_buttons_tests`.
+- [x] **Conform-on-insert** — verified already shipped (both insert variants were
+  registered actions since the insert milestone); no new code. Closes as

+- ~~[ ] **Resample-and-mute-source** — Cut (fixed by Daniel, 2026-07-26).~~ Rationale:
+  the Design View mode projection (park/hide inactive-mode content) supersedes the
+  mute-after-capture workflow; a mute action would be redundant with the dual-canvas
+  architecture. Mirror of the null-test cut precedent ("Cut (fixed by Daniel)").

-  binding for each capture/provenance action (e.g. "Capture Item → <key>") by
-  querying the SDK for the key bound to the action's command id
-  (`kbd_getTextFromCmd(cmd, SectionFromUniqueID(0))` — main section) and formatting
-  a reminder label. Unbound case degrades to the action name with a clear
-  "unbound"/"—" marker (empty/blank return handled explicitly). Split: label-text
-  formatting (binding string + fallback → label) is **pure/testable**; the SDK
-  binding query + label draw is bank_panel shell.
-- [ ] Action trigger buttons: clickable bank_panel buttons that fire the capture and
-  provenance actions directly, routing through the **existing** command-id contract
-  (`Main_OnCommand`/`KBD_OnMainActionEx` with the registered command id — the same id
-  minted at `registerAction`), never re-implementing capture. Split: button
-  hit-testing/layout math is **pure/testable** (mirror of `mode_switch`/`bank_grid`);
-  draw + command dispatch is bank_panel shell.
