docs(plan): archive landed and abandoned work per PLAN.md convention

Moves the shipped 9000 rename, Milestone 9 (abandoned), Phase D2, Phase L,
and S-VIEW-1-10 to COMPLETED.md. Restores the held-scope heading and
deduplicates Phase L.

+> touches a Phase S surface (the VST editor, the embed strip, the keyboard strip), the
+> gate is stated explicitly so the team does not chase files that are not on dev yet.
+>
+> **Settled decisions (Daniel, 2026-07-26 — see `docs/product/visual-design-language.md`
+> §6):**
+> - **DS-1 — toolkit: LICE + WDL free game, no external frameworks.** Draw the modern
+>   look with LICE directly; reuse any useful WDL/vwnd piece (skin/image helpers, draw
+>   idioms, a control like the scroll listbox) where it beats re-deriving — "don't
+>   reinvent the wheel." Reject iPlug2 / JUCE / VSTGUI (external frameworks re-opening the
+>   settled bare-SDK+LICE build shape). Keep hit-test geometry in pure CTest-covered
+>   modules — do not import vwnd's retained-mode object model wholesale.
+> - **DS-2 — visual direction: Direction B ("Neon Console") + Direction C's spectral
+>   keyboard strip. SETTLED 2026-07-26, REVISED 2026-07-26 (Daniel) — palette-only.**
+>   *Neutral surfaces (revised):* the neutral ladder moved **from near-black up into REAPER's
+>   mid-grey theme family** so the dock reads as part of REAPER, not a black slab — `bg/base`
+>   ≈ `#2b2b2b`, `bg/panel` ≈ `#333333`, `bg/cell` ≈ `#3a3a3a`, `line/hairline` ≈ `#4a4a4a`,
+>   `text/primary` ≈ `#dcdcdc`, `text/dim` ≈ `~#a0a0a0`+ (elevation-ladder discipline
+>   unchanged). *Accent layer (revised):* now a **three-accent pastel system** —
+>   `accent/primary` pastel lime green (live/active/selected), `accent/secondary` pastel teal
+>   + `accent/tertiary` pastel purple (categorical distinctions) — replacing the original
+>   single electric cyan. The spectral keyboard strip is a **pastel** sweep anchored on the
+>   three accents. *Tight WCAG pairs to re-verify against the grey ladder:* `text/dim`-on-grey
+>   (mid-grey-on-mid-grey, AA 4.5:1) and the three pastels-as-indicators on `bg/cell` (shrunk
+>   from ~15:1 to ~6:1–7:1). **A stylish/bundled-font upgrade was considered and DECLINED
+>   (Daniel):** no font bundling/redistribution — the kit keeps its current cached-font face,
+>   no new typeface. The kit palette stays abstract (roles, one constants block — three accent
+>   roles + grey neutrals), so the direction is a single-file change; final hex is locked
+>   against the theme WCAG tests within the pastel intent. Detail:
+>   `docs/product/visual-design-language.md` §2.1/§4/§6 + CONTEXT.md §Phase L.
+> - **DS-3 — dock-panel scope: a thorough layout redesign, not a light re-skin.** L2 lays
+>   out the full button inventory (including M11's action-button additions) intuitively,
+>   uncluttered, and useful — then applies the kit. Sequenced after M11 merges.

+## Phase L — must-verify-before-build
+- **LICE design-kit surfaces (L1)** — `LICE_GradRect`, `LICE_RoundRect`, AA
+  `LICE_Line`/`LICE_FLine`/`LICE_ThickFLine`/`LICE_Circle`/`LICE_FillCircle`/
+  `LICE_DrawCBezier`, `LICE_FillTriangle`/`FillTrapezoid`/`FillConvexPolygon`, and the
+  `LICE_CachedFont`/`LICE_IFont` font engine (`SetFromHFont`, AA `DrawText`, shadow/outline/
+  glow FX flags). Verified *present* in `vendor/WDL/WDL/lice/lice.h` + `lice_text.h`
+  (design-language doc §1.1); **confirm exact signatures + the `LICE_CachedFont`↔`HFONT`
+  lifecycle at build.**
+- **WDL/vwnd reuse assessment (DS-1)** — at build time, evaluate whether a vwnd piece beats
+  re-deriving it: `virtwnd-slider.cpp` / `vwnd_slider_drawknobstack` as the slider/knob
+  drawing reference, `virtwnd-listbox.cpp` as a candidate scroll listbox, `virtwnd-controls.h`
+  for `WDL_STYLE_*` gradient hooks, `virtwnd-skin.h` for image-skin helpers. Reuse where
+  useful; keep hit-test geometry pure regardless.
+- **M11 button inventory (L2)** — resolved at L2 build: inventory taken against dev after
+  M11 merged; all buttons placed by task cluster in the landed `action_bar` module.
+- **L4 re-home surface (L4)** — resolved at L4 build: three-zone layout confirmed against the
+  post-palette-revision `bank_panel`; `action_bar` extended with `ActionCluster::Tagging` +
+  `Switching`; new pure `footer_bar` module covers footer layout/hit-test.
+- **L5 refinement surface (L5)** — resolved at L5 build: `TrackPopupMenu` overflow menu
+  confirmed; tooltip mechanism resolved as **custom LICE-kit hover-delay tooltip** (`tooltip`
+  pure module; sourced from the registered action phrase, prefix stripped at draw time); item-move
+  and track-tag action ids confirmed; active-mode read confirmed via the same
+  `view().activeModeId()` the footer toggle uses.
+- **L7 model + tempo surface (L7)** — **RESOLVED at build (L7 landed).** Forks F1/F2/F3 all
+  confirmed: `TimeMap_GetTimeSigAtTime` confirmed at build for the meter stamp; SWELL stock
+  cursors chosen for drop-result cues (Reorder→IDC_SIZEALL, Move→IDC_HAND, Copy→IDC_UPARROW,
+  Replace→IDC_SIZEWE); existing pool-privilege guard reused as-is for Alt-replace. Gap navigation
+  in the grid = skip gaps (arrow keys skip empty slots). See individual entries §L7 above.

+The MIDI-playback instrument's product name is **ReaSampler 9000** (Daniel, 2026-07-26,

+is **ReaSampler 9000**. Framing + propagation surfaces:

+- [x] Propagate the display name **ReaSampler 9000** across user-visible surfaces: the VST3

+  band (currently "ReaSampler Instrument"), the S6 embed-strip label, and the Phase S docs.
+  **Do NOT change the VST3 class UID** — instances in already-saved projects key off it; a
+  UID change orphans every existing instance.
+- [x] **Rename the binary filename too (S-NAME-1 SETTLED, Daniel 2026-07-26):** rename the
+  built VST3 module (CMake `OUTPUT_NAME` / target artifact — e.g. `reasampler_9000.vst3`)
+  alongside the display strings, so the on-disk name matches the product name. Record the
+  full rename surface: **CMake output name** (the second VST3 target's artifact name), the
+  **factory vendor/name strings**, the **`IPlugView` editor title**, and the **S6 embed
+  label**. Do NOT touch the **VST3 class UID** (unchanged — the compat anchor).

+
+> **Design View sub-phase.** Extends D1's track-level mode projection to **item
+> level** via REAPER 7 fixed lanes: on a track present in both stances, each mode
+> owns a fixed lane — the active mode's lane shows and plays, the inactive mode's is
+> hidden and silenced — so a Design take and an Arrange take can share the same
+> track and time position without colliding on the view. Nothing in D1 changes.
+> Runtime floor rises to **REAPER 7** for this sub-phase (no version-gate branch;
+> below v7 it is simply unavailable). Authoritative spec: **CONTEXT.md §Two-canvas
+> sub-phase (Phase D2 / Phase E)** and the surrounding §Design View — additive phase
+> spec. Product framing: `docs/product/design-view.md` §Two-canvas direction.

+> **Deferred:** panel UI indicator for per-track lane/mode state (a per-track
+> lane-split marker). The mode switch already shows the active mode; no natural
