docs(phase-s): reconcile PLAN/COMPLETED/CLAUDE for S-VIEW Wave 2

Move S-VIEW-1..9 to COMPLETED (three-view editor + velocity spline curve v7); F3 settled (full-window Browse modal); S-VIEW-10 (curve editor UI) remains the lone open Phase S item. Add trigger_seam + velocity_curve to the module inventory.

 Sample, select+confirm loads a new capture; Zone opens on its own button, key-tracking + the
 piano-key pattern work; drop-a-capture-onto-FX instantiates a playing instance.
 
-- [ ] **S-VIEW-1 — three-view navigation model.** Retire the flat Browser|Zones toggle; introduce
-  Sample (home/default), Browse (modal overlay over Sample, select+confirm), Zone (dedicated
-  surface, own button). Empty state surfaces Browse as the dominant call-to-action. Fresh instance
-  stays silent (S10 reversal). See CONTEXT.md §S-VIEW navigation contract.
-- [ ] **S-VIEW-2 — Sample view (the new main face).** Compose the home face: enlarged **hero
-  waveform** with the S11 markers (moved from Browse), a **fenced root affordance**, the
-  **Mono/Stereo toggle** (moved from Browse), and the **"Modes-and-down" control strip** (Mode /
-  Pitch engine / AHDSR|Trigger / AD pitch env — moved from Zone's param panel, single-capture
-  one-zone storage per S15-F2). Reference grammar: Simpler / Phase Plant (labelled value-strip
-  under a hero waveform).
-- [ ] **S-VIEW-3 — envelope overlay + DRAGGABLE NODES on the hero waveform (new visual + edit
-  surface).** Draw the amp envelope (AHDSR for Gate, fade/%-length for Trigger) as a curve over the
-  Sample waveform at accurate wall-clock time. New pure `envelope_overlay` module (params + frame-
-  length → polyline; unit-tested); shell traces it in an accent hue. **The breakpoints are draggable
-  handles** (S-VIEW-F2 SETTLED — in scope, not deferred): X → segment time, Y → level on level-
-  breakpoint nodes (sustain drags both axes), monotonic-in-time + range-clamped so a drag can never
-  produce a param the slider couldn't. New pure `envelope_edit` module (node hit-test + pixel-delta→
-  clamped-param inverse map; mirror of `card_drag`; unit-tested at the clamp/monotonic boundaries).
-  Sliders stay the precise numeric surface; **both surfaces read/write the same `PerformanceZone`
-  envelope fields** — one source of truth, kept in sync by re-reading params each paint (no listener
-  chain). Node-drag commits via the same off-audio-thread path a slider edit uses (no new RT
-  surface).
-  > **Wave 1 (S-VIEW cores) ✓:** `envelope_overlay` + `envelope_edit` pure modules landed
-  > and unit-tested. **Wave 2 shell PENDING:** `reasampler_editor.cpp` must trace the overlay
-  > and wire draggable node handles; a Trigger frames↔fraction converter is owed at the module
-  > seam (documented there).
-- [ ] **S-VIEW-4 — preview-trigger + velocity knob (new, Sample view).** A button firing the
-  sampler at the loaded capture's root note through the live voice engine (off the audio-thread
-  commit path — no MIDI controller needed) + an adjacent velocity knob. **Preview velocity PERSISTS**
-  (S-VIEW-F1 SETTLED): it lands as a new top-level `previewVelocity` field on `ComponentState` via an
-  **envelope bump to v6** (`src/vst/sample_map.h`), round-tripped through the processor's existing
-  `getState`/`setState` over `IBStream` — **not** the extension's project-scoped `persist` ext-state
-  (wrong owner + wrong scope; see CONTEXT.md §S-VIEW). Zones payload untouched (independent version
-  axes); older blobs lift to a mid default. RT discipline: no `process`-thread work.
-  > **Wave 1 (S-VIEW cores) ✓:** `previewVelocity` field on `ComponentState`, envelope v5→v6
-  > bump, processor `getState`/`setState` round-trip, clamped 1..127 — all landed. **Wave 2
-  > shell PENDING:** the preview button + velocity knob UI in `reasampler_editor.cpp`.
-- [ ] **S-VIEW-5 — Browse reduced to *choosing* (modal over Sample).** Keep search + bank tabs +
-  captures grid + scroll + selection; add **confirm/cancel** (double-click loads). **Remove** the
-  large waveform preview, Mono/Stereo toggle, root keyboard-strip (all moved to Sample), and the
-  loop-point labels + track-root message (cut). Render as a full-window modal overlay (fork
-  S-VIEW-F3).
-- [ ] **S-VIEW-6 — key-tracking parameter (Zone + Sample, 0%–200%, default 100%).** A per-
-  `PerformanceZone` scalar on keyboard pitch tracking around the root (100% = 12-tone-ET, 0% = no
-  tracking, 200% = double). Additive/version-bumped, defaults 100% (bit-identical). **Key-track
-  math lives in the pure sampler core** (unit-tested note/root/keyTrack → ratio), applied in both
-  Varispeed and Preserve repitch. Surfaces as a control on the Zone param panel + Sample control
-  strip.

-  > Sample control strip.
-- [ ] **S-VIEW-7 — real piano-key pattern on the keyboard strip (new visual).** Overlay the actual
-  alternating white/black (bright/dark per palette) key pattern over the pastel spectral fill so
-  the strip reads as a keyboard. Pure `keyboard_strip` gains a natural/accidental predicate (12-
-  tone, unit-tested); shell draws the two-tone overlay. Shared by the Zone strip + Sample root
-  affordance.
-  > **Wave 1 (S-VIEW cores) ✓:** pure `isNaturalKey` predicate on `keyboard_strip`, unit-tested

-- [ ] **S-VIEW-8 — Zone view retained + wired.** Keep +Add Zone / Delete, the per-zone keyboard
-  strip (now with the piano pattern), the Low/High/Root numeric-entry legend, and the per-zone
-  param panel; add the key-tracking control. Nothing from today's Zones view dropped.
-- [ ] **S-VIEW-9 — velocity → amp transfer-curve: pure core + engine application (foundation, r10).**
-  New pure `velocity_curve` module (bezier `eval(velocity 0–127)→amp 0–1`, monotonic-in-x, clamped
-  to the 0–127×0–1 box; control-point add/move/delete x-ordered + box-clamped; hit-test + pixel-
-  delta→clamped-point inverse map; mirror of `envelope_edit`; unit-tested at eval + clamp/order
-  boundaries). Additive `velocityCurve` field on `PerformanceZone` (instrument-owned, D-B), on the
-  **zones-payload version axis**, default = **flat y=1** (R10-F1 SETTLED — Option A, Daniel
-  2026-07-27: "any velocity plays at full level"); older blobs lift to that default. **Back-compat
-  caveat: this is a deliberate non-back-compat behavior change** — the current engine does linear
-  `velocity/127`, so existing zones' soft hits will be louder after upgrade. Flagged and accepted.
-  Apply at **`Voice::start()`** — replace `velocityGain_ = velocity / 127.0` (`sampler_core.cpp:261`)
-  with `velocityGain_ = curve.eval(velocity)`, off the per-frame path (no new RT work). **BLOCKED BY
-  Wave 1 T-KEYTRK** (`PerformanceZone` schema + payload bump) — this is a LATER additive payload bump
-  sequencing AFTER T-KEYTRK merges (the two never collide on one payload version). NOT blocked by
-  T-STATE (that owns the per-instance `ComponentState` v6 axis for preview velocity). See CONTEXT.md
-  §S-VIEW velocity-curve sub-section.

   curve editor band on the **Sample view** adjacent to the envelope overlay (X = velocity 0–127, Y =
