+
+**Goal:** Split the largest extension god-module (8+ responsibilities) along the audit's named
+seams — eight TUs (Q-5 SETTLED with the T4-01 reshape, Daniel 2026-07-28): `panel_render` /

+`panel_layout` (toolbar/footer/menu rects + row/cluster builders + region geometry glue) +
+`panel_drag` (the card-drag/hover state machine — it already has a pure mirror, `card_drag`) —
+without the two new seams, `panel_render` (~700) and `panel_input` (~800) would ship over the
+~600 ceiling on day one. Split the fat `bank_panel.h` alongside (Interface Segregation).
+Preserve the audition hot path as a direct call-through, never virtual. `panel_bank_ops` becomes
+the single home for the bank-CRUD verbs that W4 will dedupe `actions.cpp` against. CONTEXT.md
+§Phase Q (bank_panel split seams; hot-path audition guardrail). See
+`docs/product/code-organization.md` §2.1, §5.
+**Verify:** CTest green at every commit. Each seam is its own TU under `shell/panel/` and every
+TU lands under the ~600-line ceiling (the Q-5 acceptance bar); the panel draws, thumbnails,
+auditions, handles input, does bank ops, and manages its window exactly as before (no behavior
+change — verify in DAW that the panel is visually and interactively unchanged). Audition/preview
+call path stays a direct call-through (no virtual dispatch, no added header→TU indirection on
+the preview path). The ~20-function public API is now segmented across the split headers.
+
+- [x] Split rendering (`draw*`/`paint*`) → `panel_render`; thumbnail compute+cache →
+  `panel_thumbnails`; toolbar/footer/menu rect + row/cluster builders + region geometry →
+  `panel_layout` (new seam, T4-01).
+- [x] Split the audio audition/preview engine → `panel_audition` — direct call-through, not
+  virtual; preview idle path unchanged.
+- [x] Split input handling (mouse/key/wheel) + new-content detection → `panel_input`; window
+  lifecycle + OS drag-out/drop-target → `panel_window`; the card-drag/hover state machine →
+  `panel_drag` (new seam, T4-01). Per-mouse-move work stays plain free-function calls (T4-28).
+- [x] Extract bank-CRUD verbs → `panel_bank_ops` (the future single owner; W4 dedupes
+  `actions.cpp` against it). Split `bank_panel.h` into per-seam headers (I).
+- [ ] Verify in DAW: panel unchanged; CTest green; no hot-path indirection added; all eight TUs
+  under the ~600 ceiling. — **PENDING**: in-DAW panel-parity verification not yet performed on
+  `phase-q` (deferred by design).
+
+**Notes/decisions:**
+- **Recorded ceiling overages (reviewer-endorsed, preserved as a durable record per CONTEXT's
+  "silent overshoot is not legitimate" rule):** `panel_input.cpp` 636, `panel_render.cpp` 613,
+  `panel_state.h` 608 — overage is comment volume; non-comment lines are ~322–369 per file; no
+  honest seam remains; bisection was rejected.
+- **Review note for the Q-W4 planning record:** `panel_bank_ops`'s verbs still embed
+  prompts/panel-state nudges — Q-W4's dedupe needs promptless inner verbs (`renameBank(id,name)`
+  etc.), not a call-site swap; `promptText`/`mintBankId` are byte-identical twins with

+## Q-W2v — split the VST god-modules (2026-07-29)
+
+> **Merged to `phase-q` 2026-07-29 (merge of `pq-w2v-vst`). Integrated suite 61/61 green,
+> reviewed-approved.**
+
+**Goal:** Close the audit's structural scope gap: the VST artifact's god-modules had no owning
+wave, and `reasampler_editor.cpp` (3065 LOC) is the largest file in the repo. Split the editor
+into eight TUs along the Sample/Browse/Zone face axis (T4-11): `editor_session` /
+`editor_controls` / `editor_layout` (pure-candidate hoist into the existing pure homes —
+`editor_geometry` is the named owner; this discharges T2-06's stranded-layout-math finding) /
+`editor_paint_sample` / `editor_paint_browse_zone` / `editor_input_sample` /
+`editor_input_browse_zone` / `editor_platform`. Split `reasampler_processor.cpp` (1164 LOC) into
+three TUs (T4-12): `processor_state` / `processor_reload` / lifecycle+`process()` kept whole.
+Split `sample_map` into resolution core vs the `component_state_io` binary codec + matching
+header split (T4-13 ≡ T2-07 — the codec grows every envelope bump; the extension stops linking
+the whole voice engine to serialize one preset blob). `sampler_core.cpp` stays whole (968 LOC) —
+a DOCUMENTED hot-path exception to the ~600 ceiling (T4-14/T4-27: envelope `tick()`s run
+per-voice-per-sample; same-TU definition is what lets the compiler inline the stack, no LTO in
+the build; a by-class split is the exact heuristic-(3) dispatch blowout); its header splits into
+`zone_params.h` + `sampler_core.h`. The `core/wire` LE byte-codec template (`putLE`/`readLE`,
+T4-20) lands here with its biggest consumer. CONTEXT.md §Phase Q (VST split seams; `sampler_core`
+exception).
+**Verify:** CTest green at every commit. Editor and processor behave identically in DAW (visual
++ interactive parity across all three faces; `process()` audio unchanged). Every new TU lands
+under the ~600-line ceiling except the one documented `sampler_core.cpp` exception. `process()`
++ its per-block helpers stay one TU; the atomic-pointer-swap reload pattern gains no virtual seam
+(T4-29); no dispatch-stack blowout anywhere (heuristic 3).
+
+- [x] Split `reasampler_editor.cpp` → the eight face-axis TUs; hoist `editor_layout`'s pure
+  geometry into the existing pure homes (`editor_geometry` — discharges T2-06).
+- [x] Split `reasampler_processor.cpp` → `processor_state` / `processor_reload` /
+  lifecycle+`process()` whole; no virtual seam on the atomic-swap pattern (T4-29).
+- [x] Split `sample_map` → resolution core + `component_state_io` codec (+ header split); the
+  extension's preset-blob path stops linking the voice engine (T4-13 ≡ T2-07).
+- [x] `sampler_core`: split `zone_params.h` out of the header; TU stays whole — documented
+  exception (T4-14/T4-27), recorded in the wave brief so nobody "fixes" it later.
+- [x] Land the `core/wire` LE byte-codec template (`putLE`/`readLE`, T4-20) with
+  `component_state_io`; other consumers rewire opportunistically.
+- [x] Rider: adopt the pure `ThumbnailKey` on the VST editor side (T2-10).
+- [ ] Verify in DAW: editor + processor unchanged; CTest green; ceiling met (one documented
+  exception); no added dispatch. — **PENDING**: in-DAW editor/processor-parity verification not
+  yet performed on `phase-q` (deferred by design).
+
+**Notes/decisions:**
+- Golden full-blob v11 fixture pins the `component_state_io` codec bytes.
+- The `src/vst/` directory is gone — all VST sources now live under the Q-W1 `core/instrument/`
+  and new `shell/instrument/` layout.
+- **Deferred/known:** `component_state_io.h` still includes `sample_map.h`→`sampler_core.h`
+  transitively (T2-07's header half — future work); the `engine` namespace is deferred
+  (`sampler_core` stays flat `reasampler`); capture-side LE rewires are left for the capture
+  family.

+
+## Q-W3 — split `main.cpp` (hoist orchestration; leave main = pointers + entry + dispatch) (2026-07-29)
+
+> **Merged to `phase-q` 2026-07-29 (merge of `pq-w3-main`). Integrated suite 61/61 green,
+> reviewed-approved.**
+
+**Goal:** Reduce `main.cpp` (1897 LOC at the Q-W0 census) to its actual job — API pointers +
+`ReaperPluginEntry` + dispatch — by hoisting four TUs (T4-02 reshape, SETTLED with Q-5, Daniel
+2026-07-28 — the planned three left `capture_orchestrator` at ~885, over the ceiling):
+`capture_orchestrator` (`RunCapture` / `captureAndIndexOne` / `renderOffline` / single-capture +
+realtime/insert action bodies — lands ~450), `capture_batch` (the batch family +
+`RunRecaptureFromSource` + the two RAII selection guards — recapture is planner-driven like batch
+and shares the guard machinery), `scope_resolve` (`resolveRange`/`resolveRazorRange`/
+`collectSelectedTracks` + provenance assembly inputs), and `realtime_lifecycle` (the
+realtime-capture state machine + globals). `FxBypassGuard` moves out but stays a stack RAII
+object (precision-critical); the realtime idle tick stays a single pointer test. Q-W0 riders
+owned by this wave (all SETTLED 2026-07-28): delete `ICaptureBackend` (T4-26 — one deriver, zero
+polymorphic call sites; `OfflineRenderBackend` becomes concrete; the CLAUDE.md/CONTEXT "two
+backends behind one interface" correction rides this wave's own commit, not earlier); the shared
+`stampCaptureSample` capture-epilogue dedupe (T2-09); the `capture_realtime_finalize` split
+riding the Q-9 rename (T4-08); the `makeUniqueTag` per-session monotonic-counter fix (T1-11); and
+the WAV/RIFF consolidation (audit §4e) — one pure `wav_codec` owner (walker + layout + build +
+patch), absorbing `ingest.cpp`'s pure WAV build helpers (T2-08 / T4-23 / T4-10). CONTEXT.md
+§Phase Q (main split seams; FxBypassGuard + realtime-tick guardrails). See
+`docs/product/code-organization.md` §2.1, §3.
+**Verify:** CTest green at every commit. Capture (offline + realtime + batch + recapture) behaves
+identically in DAW; the null test still nulls, bit-identical repeats still match (the precision
+invariants `FxBypassGuard` protects are unchanged); capture ≠ placement holds (no hoisted `Run*`
+path gains an `InsertMedia` call). The realtime idle fast-path is still a single pointer test.
+`main.cpp` is now pointers + entry + dispatch only. The four hoisted TUs + `wav_codec` land under
+the ~600 ceiling; the WAV/RIFF layout has one pure owner (the dedup-by-hash and null-test
+invariants now rest on one implementation); `ICaptureBackend` is gone with no behavior change and
+the CLAUDE.md/CONTEXT description is corrected in the same commit.
+
+- [x] Hoist capture orchestration → `capture_orchestrator` (`shell/capture/`); keep
+  `FxBypassGuard` a stack RAII object as it moves (precision-invariant-critical).
+- [x] Hoist the batch family + `RunRecaptureFromSource` + the two RAII selection guards →
+  `capture_batch` (fourth hoist, T4-02) so `capture_orchestrator` lands ~450.
+- [x] Hoist scope/source resolution + provenance assembly inputs → `scope_resolve`.
+- [x] Hoist the realtime-capture lifecycle state machine + globals → `realtime_lifecycle`; idle
+  tick stays a single pointer test.
+- [x] Leave `main.cpp` = API-pointer ownership + `ReaperPluginEntry` + dispatch; move to `app/`.
+- [x] Naming rider (Q-9 — SETTLED, Daniel 2026-07-28: yes): align the `capture_realtime` (shell)
+  / `realtime_record` (pure) word-order inversion to the house shell↔core convention — the pure
+  module takes the stem `capture_realtime`, the shell takes the suffix (`drag_out`↔`drag_out_win`
+  is the model). Split `capture_realtime_finalize` (async lifecycle vs file-side finalize) in the
+  same surgery (T4-08). No rename on a file this wave isn't already touching (Q-7).
+- [x] Delete `ICaptureBackend` (T4-26): `OfflineRenderBackend` becomes concrete; correct the
+  CLAUDE.md/CONTEXT "two backends behind one interface" description in the same commit.
+- [x] Dedupe the capture-stamp epilogue → shared `stampCaptureSample` (T2-09 — the divergent bits
+  stay in the realtime caller); fix `makeUniqueTag` with a per-session monotonic counter, both
+  call sites (T1-11 — same-second batch captures currently collide silently).
+- [x] WAV/RIFF consolidation rider (audit §4e — SETTLED, Daniel 2026-07-28): one pure `wav_codec`
+  owner (chunk walker + layout + build + patch), absorbing `ingest.cpp`'s pure WAV/PCM build
+  (T4-10 — the ingest shell drops to ~500 and the WAV build gains a test target).
+- [ ] Verify in DAW: null test nulls, bit-identical repeats match, capture≠placement holds; CTest
+  green; no realtime-tick branch-shape change. — **PENDING**: in-DAW null-test /
+  bit-identical-repeats verification not yet performed on `phase-q` (deferred by design).
+
+**Notes/decisions:**
+- `wav_codec_tests` replaces `wav_trim_tests`; `capture_realtime_tests` replaces
+  `realtime_record_tests`.
+- **Known open:** `wav_trim.h`'s transitional forwarding shim still has three live includers
+  (`sample_map.h`, `editor_session.cpp`, `processor_reload.cpp`) — repoint-and-retire is a named
+  follow-up; `ingest.cpp` trimmed to 567 LOC but keeps the `namespaces.h` shim (`ingest` + `view`
+  remain the shim's unowned consumers).

-- [ ] Hoist capture orchestration → `capture_orchestrator` (`shell/capture/`); keep
-  `FxBypassGuard` a **stack RAII** object as it moves (precision-invariant-critical).
-- [ ] Hoist the batch family + `RunRecaptureFromSource` + the two RAII selection guards →
-  **`capture_batch`** (fourth hoist, T4-02) so `capture_orchestrator` lands ~450.
-- [ ] Hoist scope/source resolution + provenance assembly inputs → `scope_resolve`.
-- [ ] Hoist the realtime-capture lifecycle state machine + globals → `realtime_lifecycle`;
-  **idle tick stays a single pointer test.**
-- [ ] Leave `main.cpp` = API-pointer ownership + `ReaperPluginEntry` + dispatch; move to `app/`.
-- [ ] **Naming rider (Q-9 — SETTLED, Daniel 2026-07-28: yes):** align the `capture_realtime`
-  (shell) / `realtime_record` (pure) word-order inversion to the house shell↔core convention —
-  the pure module takes the stem `capture_realtime`, the shell takes the suffix
-  (`drag_out`↔`drag_out_win` is the model). Split `capture_realtime_finalize` (async lifecycle
-  vs file-side finalize) in the same surgery (T4-08). No rename on a file this wave isn't
-  already touching (Q-7).
-- [ ] Delete `ICaptureBackend` (T4-26): `OfflineRenderBackend` becomes concrete; correct the
-  CLAUDE.md/CONTEXT "two backends behind one interface" description **in the same commit**.
-- [ ] Dedupe the capture-stamp epilogue → shared `stampCaptureSample` (T2-09 — the divergent
-  bits stay in the realtime caller); fix `makeUniqueTag` with a per-session monotonic counter,
-  both call sites (T1-11 — same-second batch captures currently collide silently).
-- [ ] **WAV/RIFF consolidation rider (audit §4e — SETTLED, Daniel 2026-07-28):** one pure
-  `wav_codec` owner (chunk walker + layout + build + patch), absorbing `ingest.cpp`'s pure
-  WAV/PCM build (T4-10 — the ingest shell drops to ~500 and the WAV build gains a test target).
-- [ ] Verify in DAW: null test nulls, bit-identical repeats match, capture≠placement holds;
-  CTest green; no realtime-tick branch-shape change.
+> **Landed on `phase-q` (2026-07-29, merge of `pq-w3-main`). Integrated suite 61/61 green,

+> `core/capture/capture_realtime`, shell `capture_realtime_shell` + `capture_realtime_finalize`
+> split, T4-08); `stampCaptureSample` dedupe (T2-09, divergent time-sig behavior preserved via
+> caller arg); `makeUniqueTag` gains a per-session monotonic counter (T1-11 behavior fix — stems
+> now `<epoch>-<n>` / `rt-<epoch>-<n>`; the per-process residual is documented in-code); one pure
+> `wav_codec` RIFF owner absorbs `wav_trim` + `ingest`'s WAV build + content hashes, with golden
+> hash literals pinned (`wav_codec_tests` replaces `wav_trim_tests`; `capture_realtime_tests`
+> replaces `realtime_record_tests`). See `COMPLETED.md` for the full narrative.

+> **Known open:** `wav_trim.h`'s transitional forwarding shim still has three live includers
+> (`sample_map.h`, `editor_session.cpp`, `processor_reload.cpp`) — repoint-and-retire is a named
+> follow-up; `ingest.cpp` is trimmed to 567 LOC but keeps the `namespaces.h` shim (`ingest` +
+> `view` remain the shim's unowned consumers).

+> by design, not yet performed.
 
 ## Q-W4 — split `actions.cpp` + dedupe bank verbs against `panel_bank_ops`
 **Goal:** Split the two unrelated command-id families in one TU (1016 LOC at the Q-W0 census —
