 - `capture_realtime` (`core/capture`, **renamed from `realtime_record` in Q-W3** — the Q-9 naming rider: pure module takes the stem, the shell takes the suffix, matching `drag_out`/`drag_out_win`) — the M8 realtime-record pure logic: capture scope + FX-tap point → `I_RECMODE`/`I_RECMODE_FLAGS` values, wet/dry → tap point, the recorded-file → `Sample` mapping, and the async record-phase state machine. Depends on `bank_model` for the plain `Sample`/`SourceMode` types. The transport/temp-track/send recipe lives in the shell (`shell/capture/capture_realtime_shell.cpp` + `capture_realtime_finalize.cpp`).
 - `batch_capture` — pure batch-capture planner: maps source ranges to capture units and aggregates results.
 - `capture_paths` — the REAPER-free path arithmetic behind offline capture: bank-subfolder + unique-filename derivation (`deriveBankPaths`, forward-slash form, no filesystem touch), the absolute-render-dir vs. project-relative-index-path split (`BankPaths`), the persist-side inverse (`resolveBankFile`, `projectDirOfRpp`), the Save-As bank-relocation plan (`deriveRelocationPlan`), and the GUID-primary project-identity classifier (`classifyProjectTransition` → `NoOp`/`Load`/`SaveAsRelocate`) the persist-poll timer drives.
+- `capture_name` — the REAPER-free composition of one capture's label + file-stem base from its source-track name(s), a local-calendar discriminator (`MM-DD HHMM`, from the shell's clock read), and an optional batch ordinal. The label and the stem deliberately diverge: the stem still passes through `capture_paths::sanitizeStem` (so a name that sanitizes to nothing files as `capture`), while the label keeps the source name verbatim. Stem uniqueness stays entirely `makeUniqueTag`'s — this module never disambiguates.
 - `insert_plan` — the REAPER-free logic behind the `insert` shell (M6): computes the `InsertMedia` `mode` bitmask from an `InsertOptions` struct (placement target, tempo-conform ratio, preserve-pitch flag), guaranteeing the &4 stretch-to-time-selection bit is never set and that no tempo bits are set when `conform == None`.
 - `render_settings` — the REAPER-free logic behind the capture action family: `SourceMode` → `RENDER_SETTINGS` bit mapping, `P_RAZOREDITS` string parsing + range-union bounds, razor-else-time range inference, the FX-scope bypass plan (`fxBypassPlanFor`), the tail-mode → `RENDER_TAILFLAG`/`RENDER_NORMALIZE`/`RENDER_TRIMEND` mapping (`tailRenderSettingsFor`) and its realtime-window analog (`realtimeRecordWindowEnd`), and the capture-action taxonomy table (`captureActionTable`) `main.cpp` iterates to register the CAPTURE_ITEM/CAPTURE_TRACK family.
 - `render_window` — the REAPER-free frame arithmetic behind exact capture bounds: `frameCountFor` (the frame count a project-time window occupies at the project rate — the number the offline backend checks the rendered file against before landing it, so a widened render is refused rather than banked) and `itemExtentPrintsWindow`, the predicate `render_settings::sourceModeForScope` consults to decide whether REAPER's selected-items render source can express a requested window at all.
