# PLAN.md — ReaSampler milestone roadmap
|
||
|
||
Living milestone roadmap for ReaSampler. Derived from CONTEXT.md's 11-step build
|
||
order; CONTEXT.md remains the authoritative spec — this file is the tickable
|
||
checklist, not a re-statement of the spec. When a point lands, doc-keeper removes
|
||
it here and appends it to `COMPLETED.md`.
|
||
|
||
**Conventions**
|
||
- One checkbox `- [ ]` = one discrete, independently-landable point.
|
||
- Each milestone opens with a **Goal** (one line) and a **Verify** criterion
|
||
(the acceptance gate; precision invariants pulled in where one applies).
|
||
- Verify-in-DAW points require a manual REAPER run; pure points are gated by CTest.
|
||
- "See CONTEXT.md §…" points at the authoritative detail — do not duplicate it here.
|
||
|
||
---
|
||
|
||
## Open questions to resolve during build
|
||
Carried from CONTEXT.md §Open questions — keep visible until each is closed by a
|
||
landed milestone.
|
||
|
||
- **`parseInt` narrowing hardening:** `src/bank_model.cpp` `parseInt` casts
|
||
`int64_t → int` via `static_cast` without a range check; integers that fit
|
||
in int64 but exceed `INT_MAX` are implementation-defined. Hardening candidate
|
||
— add bounds check before the cast when integer-field validation is in scope.
|
||
- **Capture send/routing isolation (TODO):** The FX-scope capture neutralizes out-of-scope FX, gain, and pan — but NOT aux **sends**. So a downstream coloring send (e.g. a folder → reverb-track send) still routes and blends the reverb into an item/track capture, past the intended isolation point. A true item-level capture should be taken at the isolated graph point — the target scope's output before out-of-scope track FX/gain/pan **and** before out-of-scope aux/parallel sends. The hard part: distinguish **source routing that must be preserved** (e.g. a MIDI send T1→T2 where T2's synth is where a MIDI item's audio is actually produced — the "item level" for that MIDI item is T2's synth output) from **coloring sends that must be excluded** (folder→reverb). Repro: folder F1; T1 (MIDI) sends MIDI to T2 (synth); T1+T2 → F1; F1 sends to reverb T3; capturing the MIDI item on T1 currently includes the reverb, should be isolated to T2's synth output pre-F1 with the MIDI send preserved and the reverb send excluded. Likely approach: snapshot + mute out-of-scope tracks' aux sends during the render while preserving the main/source signal path — needs a rule for which sends are load-bearing.

||
# Phase D2 — Two-canvas (item-level mode projection; additive to D1)
|
||
|
||
> **Phase D2 is functionally complete** — D2-W1, D2-W2, D2-W3-A, D2-W3-B all landed; see `COMPLETED.md`.
|
||
>
|
||
> **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
|
||
> cheap home for a per-track indicator was found in the bank panel. Explicitly
|
||
> deferred — not silently dropped. Can be picked up later if wanted.
|
||

|
||
|
||
# Phase S — MIDI-playback instrument (native VST3 sampler; a second build artifact)
|
||
|
||
> **Landed on dev (merged 2026-07-27); DAW verification pending Daniel's smoke test.**
|
||
> S1–S18 and the product-name/binary-rename work are all on dev. The cross-artifact
|
||
> ingest relay (S13 bullet) was explicitly DEGRADED and remains deferred — see below.
|
||
> Completed material archived in `COMPLETED.md`. Authoritative spec: **CONTEXT.md
|
||
> §MIDI-playback instrument — additive phase spec (Phase S)**. Product framing:
|
||
> `docs/product/midi-playback.md`.
|
||
>
|
||
## S13 — cross-artifact ingest relay (deferred)
|
||
|
||
> **SPIKE VERDICT (ps-w12, 2026-07-27): DEGRADED — relay deferred.** The instrument's
|
||
> REAPER bridge (`reaper_bridge`) is deliberately READ-ONLY; a relay would need a new
|
||
> instrument WRITE seam into ext-state and an extension-side timer poller servicing a
|
||
> drop-ingest inbox key with a claim/clear nonce — the same cross-process handshake race
|
||
> the S17 spec rejected for alternative (A). Both the read-only-instrument boundary and
|
||
> the new poller are load-bearing design calls, so the relay is deferred to a future wave.
|
||
> The shipped ingest gesture stays drop-onto-docked-panel (S8). The degrade path (editor
|
||
> shows a "drop files onto the ReaSampler bank panel to add them" affordance) landed as
|
||
> part of Phase S. See `COMPLETED.md` §S13 for full context.
|
||
|
||
- [ ] Cross-artifact ingest relay: the editor hands the dropped path + this instance's
|
||
identity to the extension as a bank-ingest request over an agreed seam. DEFERRED —
|
||
relay mechanism proved load-bearing to redesign; drop-onto-panel (S8) is the shipped
|
||
ingest path. Requires (a) a new instrument WRITE seam into ext-state and (b) an
|
||
extension-side timer poller + claim/clear nonce. A future wave when the design is ready.
|
||
|
||
## Phase S — product name (ReaSampler 9000)
|
||
The MIDI-playback instrument's product name is **ReaSampler 9000** (Daniel, 2026-07-26,
|
||
on DAW-testing the S1–S6 instrument). The extension remains **ReaSampler**; the instrument
|
||
is **ReaSampler 9000**. Framing + propagation surfaces:
|
||
`docs/product/midi-playback.md` §Product name.
|
||
|
||
- [ ] **Compat verification (must-DAW-verify before shipping the rename):** the working
|
||
assumption is that REAPER **rebinds a saved instance by its VST3 class UID, not by the
|
||
module filename**, so a filename rename with an unchanged UID keeps saved projects working
|
||
(existing instances still resolve). **This is not yet confirmed from source** — a web
|
||
check surfaced a JUCE/VST3-replace-VST2 case suggesting REAPER's binding is more nuanced
|
||
than "UID only" (it can involve an FXID match), so treat UID-rebind as **to-verify, not
|
||
asserted fact**. **DAW-verify:** save a project with a ReaSampler 9000 instance under the
|
||
old filename, rename the module, reopen — confirm the instance rebinds and restores its
|
||
state. If REAPER does key partly on filename, fall back to keeping the current filename
|
||
(display-strings-only) and record that as the shipped choice.
|
||
|
||
## Phase S — held and optional-forever (noted, not specified)
|
||
|
||
- **Tier 2 — "expressive" (HELD).** Velocity layers, round-robin (anti-machine-gun),
|
||
full ADSR, per-sample tuning/gain trim, sustain loops. The next depth increment once
|
||
Tier 0–1 proves the instrument belongs — **its points are not drawn up here.**
|
||
- **Tier 3 — "instrument polish" (optional-forever).** Filters, filter/pitch
|
||
envelopes, LFOs, per-voice pan, choke groups, a modest FX slot. A direction to leave
|
||
room for, never a commitment. **Note:** S16 lands the *pitch* envelope + the Varispeed/
|
||
Preserve pitch-engine mode early (Daniel's directive) — the Tier-3 "filter/pitch envelopes"
|
||
line now means the *filter* envelope + LFOs remainder.
|
||
- **Sinc Varispeed-quality upgrade (HELD — WDL_Resampler).** `WDL_Resampler`'s sinc mode
|
||
beats the core's 2-point linear interp for **Varispeed** base-repitch quality (see the S16
|
||
WDL finding). An optional per-voice quality toggle (linear default / sinc), RT-suitable but
|
||
heavier. Held as a Tier-2/3 quality option — not needed for S15/S16, not scheduled. (A
|
||
resampler couples duration, so it is a Varispeed-quality option only, **not** a Preserve
|
||
engine.)
|
||
- **WDL_SimplePitchShifter swap (HELD — fork S16-F2 route a).** `WDL_SimplePitchShifter`
|
||
as a drop-in swap for the `pitch_shift` pure module if the hand-rolled OLA onset latency
|
||
or warble proves musically unacceptable. Same `PitchEngine::Preserve` contract behind the
|
||
seam. WDL excluded from the shipped build by include-chain (windows.h); held as the
|
||
quality/latency alternative.
|
||
- **Trigger choke-on-note-off (HELD — fork S15-F1).** A future option for Trigger mode to
|
||
*cut* (choke) on note-off or on a same-group re-trigger (hi-hat open/closed). Deliberately
|
||
out of S15 scope (Trigger ignores note-off entirely there); a Tier-3 choke-group direction.
|
||
|
||
## Phase S — editor view-model redesign (three views: Sample / Browse / Zone)
|
||
|
||
> **Additive Phase S sub-phase (S-VIEW; Daniel, 2026-07-27, r9).** Re-partitions the ReaSampler
|
||
> 9000 editor from a two-view toggle into a **three-view model where the loaded sample is the
|
||
> home** — Sample (default face), Browse (modal picker over Sample), Zone (dedicated keymap
|
||
> surface). Adds three performance parameters (key-tracking, preview velocity, and the r10
|
||
> velocity→amp transfer curve) and three visual components (envelope overlay, real piano-key
|
||
> pattern, and the r10 velocity-curve editor), and frames two engineering prerequisites
|
||
> (drop-to-FX bug, default window size). An **editor** redesign — the S3 voice engine, keymap
|
||
> resolution, and read-only-over-bank contract are **unchanged**; component state extends
|
||
> additively for key-tracking; VST3 class UID unchanged. Authoritative spec: **CONTEXT.md §Phase
|
||
> S — editor view-model redesign (S-VIEW)**. Product framing: `docs/product/midi-playback.md`
|
||
> §Addendum r9. When a point lands, doc-keeper moves it to `COMPLETED.md`.
|
||
>
|
||
> **Depends on Phase S being on dev** (this redesigns Phase S editor shells —
|
||
> `reasampler_editor.cpp` + the pure `src/vst/` geometry modules). **Phase L L3 is FINISHED and
|
||
> merged** (2026-07-27, commit `c53683e` — `reasampler_editor.cpp` + `reasampler_embed.cpp`
|
||
> restyled through the L1 kit). S-VIEW builds the new three-view layout **directly on the current
|
||
> L3 look-and-feel as its baseline — one implementation pass, styled correctly from the start.**
|
||
> There is **no two-pass "land S-VIEW then restyle through L3"** — L3 already happened; every new
|
||
> S-VIEW surface (Sample face, Browse modal, Zone surface, envelope overlay + node handles,
|
||
> piano-key strip, preview cluster) is drawn through the L1 kit at build time, inheriting the L3
|
||
> palette and component-draw grammar. Restyle-after is not a concern.
|
||
|
||
**Goal:** A three-view editor that makes "pick a capture, tune it, play it" fast, easy, and fun —
|
||
Sample is home, Browse is an easy-to-summon modal picker, Zone is the deliberate keymap surface.
|
||
**Verify (in DAW):** open on a 1080p screen → full Sample face (hero waveform + envelope overlay +
|
||
fenced root + preview-trigger + control strip) with no scroll; Browse opens as a modal over
|
||
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.
|
||
|
||
### Phase S editor Wave B — Sample-face recomposition (r11; Daniel, 2026-07-27)
|
||
|
||
> Daniel's post-landing DAW pass on the S-VIEW editor: **all linear sliders → small radial
|
||
> knobs** grouped into a fenced knob deck (envelope controls grouped as a unit); the **mode
|
||
> toggles compact**, not full-width; the **inline velocity-curve box → a miniature curve
|
||
> preview button + full-size popup editor** (right-click deletes a node in the popup); the
|
||
> **hero waveform full-width**. Authoritative layout spec: **CONTEXT.md §S-VIEW → "The
|
||
> Sample-face recomposition (r11)"** (band order, group taxonomy, cell metrics, popup
|
||
> geometry, inventory contract — nothing silently dropped). Product framing:
|
||
> `docs/product/midi-playback.md` §Addendum r11. All drawing through the L1 kit; all
|
||
> layout/hit-test in pure geometry modules.
|
||
>
|
||
> **S-VIEW-11, S-VIEW-12, and S-VIEW-13 have all landed** — FB1 (merged 2026-07-27, suite
|
||
> 55/55) brought the knob deck + master gain + curve popup + full-width hero; FB2 (merged
|
||
> 2026-07-28, suite 55/55) brought Zone-panel parity. **Phase S editor Wave B (r11) is
|
||
> complete.** See `COMPLETED.md` for both FB entries.
|
||
|
||
**Open forks** — **R11-F1** (hero height vs. default window) SETTLED at FB1 build: elastic
|
||
hero, 840×620 default kept. **R11-F2** (Zone-panel parity) SETTLED at FB2 build: knob deck
|
||
+ curve popup adopted on the Zone panel; `param_slider` slider rows retired on that surface.
|
||
|
||
### Phase S editor redesign — forks (Daniel's to call)
|
||
*(r9/r10 forks all settled: S-VIEW-F1 and S-VIEW-F2 SETTLED 2026-07-27 — folded into S-VIEW-4 /
|
||
S-VIEW-3. F1: preview velocity persists via envelope-v6 `ComponentState`. F2: envelope nodes are
|
||
draggable via the pure `envelope_edit` module. R10-F1 SETTLED 2026-07-27 — Option A flat y=1,
|
||
folded into S-VIEW-9. S-VIEW-F3 SETTLED — full-window overlay, implemented as Browse renders as a
|
||
full-window modal over Sample (landed in S-VIEW-1/S-VIEW-5). **r11 forks all settled: R11-F1
|
||
SETTLED at FB1 build (elastic hero, 840×620 default kept); R11-F2 SETTLED at FB2 build (Zone
|
||
panel adopts knob deck + curve popup, `param_slider` slider rows retired on that surface).**)*

# Phase Q — Quality (structural reorganization; zero-runtime-cost)
|
||
|
||
> **New pillar, own lettered namespace, and — uniquely — the LAST structural pillar.** Phase
|
||
> Q is a **pure structural refactor**: it reorganizes `src/` into a healthier shape (more
|
||
> encapsulation, granular namespaces, `core/`/`shell/`/`app/` subdirectories) against a stated
|
||
> quality bar — *"mtytel Vital is my code reference for quality"* — to bring the codebase
|
||
> "into the realm of something I can stand to look at." It ships **no feature and changes no
|
||
> behavior**: the test suite passing unchanged is the proof of correctness. Namespaced **`Q`
|
||
> (Quality)** — M/D/B/R/V/S/L are all taken; `Q` names the *end* (the quality bar), the reorg
|
||
> being the *means*. Authoritative spec: **CONTEXT.md §Phase Q — structural reorganization
|
||
> (reorg spec)**. Product framing, the Vital-grounded target shape, the grep-verified SOLID
|
||
> audit that is the evidence base, and the settled/recommended fork record (Q-1..Q-6):
|
||
> `docs/product/code-organization.md`. When a point lands, doc-keeper moves it to
|
||
> `COMPLETED.md`.
|
||
>
|
||
> **THE GATE (load-bearing — state first; reconciled to reality 2026-07-27).** Phase Q is
|
||
> **gated on the tree being otherwise quiescent.** Daniel's plain readiness target: **"when
|
||
> Phase S and L3 are finished."** **As of 2026-07-27 both gate conditions are satisfied:**
|
||
> Phase S merged to dev (2026-07-27); Phase L L3 (the VST restyle) merged to dev
|
||
> (2026-07-27, commit `c53683e`) — **Phase L is complete** (L1/L2/L3/L4/L5/L6/L7 all
|
||
> landed, see `COMPLETED.md`). **D2** is functionally complete (D2-W1..W3-B landed; the
|
||
> lone open item, a per-track lane-split panel indicator, is *explicitly deferred*, not a
|
||
> blocking residual). **M9** (slots) is **abandoned** (Daniel, 2026-07-27) — will not be
|
||
> built. D2 is named in the gate only so that *reactivating* its deferred panel indicator
|
||
> re-arms the quiescence condition; neither D2 nor M9 blocks the gate today. *Why the gate:* Phase Q
|
||
> touches **nearly every file in `src/`** (relocate into subdirectories, re-namespace every
|
||
> header, split the four largest TUs, plus the §2b renames). Every large in-flight branch
|
||
> (Phase S on its worktree, and L3 once it lands) is diffed against the *current flat
|
||
> layout*; landing a rename-and-relocate-everything reorg mid-flight forces every open
|
||
> branch through the worst conflict class (every hunk moved, every qualified reference
|
||
> changed) — a combinatorial re-resolution, not a linear one. Phase Q is *last* precisely
|
||
> because it reshapes the ground every other pillar stands on. Landing it early taxes every
|
||
> subsequent phase; landing it last taxes nothing. **The gate is now satisfied — Phase Q
|
||
> may begin, entering at the Q-W0 audit wave** (the structural waves Q-W1+ do not begin until
|
||
> Q-W0's triage closes and Daniel signs off — see the Q-W0 sub-gate above).
|
||
>
|
||
> **M9 disposition — resolved (Daniel, 2026-07-27): abandoned.** M9 is out; it will not be
|
||
> reactivated. The gate remains satisfied; no re-arm condition applies.
|
||
>
|
||
> **PRE-RESTRUCTURE AUDIT WAVE (Q-W0 — added 2026-07-27, Daniel's ask; runs FIRST).** Before any
|
||
> structural point (Q-W1+) begins, Phase Q now opens with a **functional + DSP quality audit**
|
||
> (`Q-W0`) — a thorough static analysis of the code from a *functional-correctness* and
|
||
> *algorithm-quality* point of view, complementary to (not a repeat of) the grep-verified
|
||
> SOLID/naming audit that already grounds Q-W1..Q-W6. Q-W0 hunts DSP smells (close eye on the pitch
|
||
> engine), reinvented wheels, duplicate code, poor-quality algorithms, leaky pure/shell boundaries,
|
||
> and domain-modeling smells around env-coupled constants; it produces a written, triaged findings
|
||
> report. **The gate to begin Q-W1 is that Q-W0's triage is complete and Daniel has signed off on
|
||
> each finding's disposition** (fix-now vs. document-and-defer). Q-W0's findings may add or reshape
|
||
> downstream Q-W1..Q-W6 points; fixes that Q-W0 classifies fix-now are remediated in Q-W0 (or folded
|
||

|
||
> **Q-W0 SIGN-OFF: COMPLETE (Daniel, 2026-07-28).** The audit ran as four parallel tracks (T1 DSP,

> T2 architecture, T3 env-coupled constants, T4 sizing/placement — **59 findings**; report
|

|
||

## Q-W0 — pre-restructure functional + DSP quality audit (runs FIRST; gates Q-W1)
|
||
**STATUS (2026-07-29): audit COMPLETE, triage COMPLETE, sign-off COMPLETE, fix-now
|
||
remediations LANDED — Q-W0 is fully closed.** The findings report is committed
|
||
(`docs/product/code-quality-audit.md`; track appendices in `docs/product/audit-notes/` — T1
|
||
DSP, T2 architecture, T3 env-constants, T4 sizing/placement; 59 findings). Daniel approved
|
||
every disposition 2026-07-28. The six approved fix-now remediations plus seven review riders
|
||
landed 2026-07-28 (merge `546927e`) — see `COMPLETED.md`. **Q-W1 has since landed on top of
|
||
this closure** (see `COMPLETED.md`).
|
||
**Goal:** Before a single structural point moves, perform a **thorough static/functional audit** of
|
||
the codebase and produce a **written, triaged findings report**. This is the *functional-correctness
|
||
and algorithm-quality* complement to the grep-verified SOLID/naming audit that already grounds
|
||
Q-W1..Q-W6 (§2/§2b of `docs/product/code-organization.md`) — it goes deeper on *does the code do the
|
||
right thing well*, not *where does the responsibility live*. It hunts, across the whole `src/` tree:
|
||
duplicate code, reinvented wheels, poor-quality algorithms (**close eye on the pitch engine**),
|
||
numerical-robustness and artifact hazards in the DSP paths, leaky pure/shell boundaries, and
|
||
**domain-modeling smells around env-coupled constants** (values stored in a frame/rate/DPI/tick-coupled
|
||
domain that should be stored rate-free and resolved at use). Every finding is **classified for
|
||
disposition**: *eliminate-before-restructure* (fix-now) vs. *document-and-defer* (with rationale).
|
||
Nothing structural (Q-W1+) begins until this wave closes and Daniel signs off on the disposition of
|
||
every finding. CONTEXT.md §Phase Q (Q-W0 audit scope + triage). See
|
||
`docs/product/code-organization.md` §2c.
|
||
**Verify:** A findings report exists and is complete over the named audit surfaces (DSP/audio incl.
|
||
pitch; architecture smells; env-coupled-constant domain-modeling smells). **Every finding is
|
||
triaged** (fix-now vs. documented-and-deferred, each with a one-line rationale). Fix-now findings are
|
||
either remediated in this wave or explicitly assigned to the downstream wave that already touches the
|
||
file (recorded per finding); no fix-now finding is left implicit. Any behavior-changing remediation
|
||
lands with its module's CTest executable green and (where a DSP path changes audibly) a stated
|
||
before/after listening or null check. **The gate to Q-W1 is: triage complete + Daniel signed off.**
|
||
**Depends on:** the GATE (tree quiescent). Precedes every other Q wave — Q-W1 depends on Q-W0.
|
||
|
||
- [ ] **DSP / audio audit — close eye on pitch.** Assess *algorithm quality* (correctness,
|
||
artifacts, numerical robustness, interpolation quality, reinvented-wheel vs. established DSP
|
||
technique) across: `src/vst/pitch_shift` (hand-rolled OLA pitch-preserve — window/overlap choice,
|
||
phase handling, transient/formant behavior, buffer edges), `sampler_core` (repitch ratio math,
|
||
interpolation order/quality, loop-point crossfade, voice-stealing correctness/click behavior),
|
||
`peaks` (envelope min/max binning), `wav_trim` (decay-scan threshold + truncate plan), and the
|
||
capture/tail paths. **Pitch-remediation depth (Q-11 SETTLED, Daniel 2026-07-27): defer to
|
||
findings** — default document-and-defer; only if the audit surfaces artifacts that matter, weigh a
|
||
bounded OLA fix (window/overlap/edge tuning) **before** a technique replacement. A technique
|
||
replacement (phase-vocoder / WSOLA) reshapes `pitch_shift`, spills a downstream Q-wave point, and is
|
||
a **Daniel decision at triage time, not an automatic Q-W0 action** — Q-W0 surfaces the
|
||
recommendation, Daniel calls it.
|
||
- [ ] **Architecture-smell audit.** Duplicate code, reinvented wheels, poor abstractions, and any
|
||
leaky pure/shell boundary (a `core/` module reaching a REAPER/host type, or geometry/algorithm
|
||
math living untestable in a shell). Cross-check against — but do not merely restate — the §2/§2b
|
||
SOLID/naming findings; Q-W0's contribution is the *functional* smells those audits didn't target.
|
||
- [ ] **Env-coupled-constant domain-modeling audit (explicit smell category).** Flag ANY value
|
||
stored in a frame/rate/DPI/tick-coupled domain that should be stored **rate-free and resolved at
|
||
the point of use** — per the load-bearing invariant that wall-clock times are rate-free SECONDS
|
||
resolved against the live project rate (`sample_map`), with NO hardcoded sample rates in `src/`.
|
||
Treat this as **domain-modeling** (store rate-free, resolve at use), **not** "rescale by rate."
|
||
There was a prior incident here — envelope times stored in the frame domain — so this is a
|
||
first-class category, not a footnote. Sweep envelope times, loop points, fade lengths, tail
|
||
lengths, and any UI geometry constant that silently assumes a DPI/rate.
|
||
- [ ] **Triage + report.** Write the findings report as a **committed doc,
|
||
`docs/product/code-quality-audit.md`** (Q-10 SETTLED, Daniel 2026-07-27 — beside the SOLID/naming
|
||
audit, not a tracked issue list); classify each finding fix-now vs. document-and-defer with a
|
||
one-line rationale; for each fix-now, note whether it is remediated in Q-W0 or assigned to the
|
||
downstream wave that already opens the file. Deferred findings carry a documented rationale so they
|
||
are a decision, not an omission.
|
||
- [ ] **Sign-off gate.** Daniel reviews the triage and signs off on each disposition. Q-W1 does not
|
||
begin until this is done; fold any new/reshaped downstream points the audit surfaces into
|
||
Q-W1..Q-W6 before starting them. **DONE (Daniel, 2026-07-28): all 59 dispositions approved as
|
||
proposed; the §3 plan reshape and §4 decisions are folded into Q-W1..Q-W6 + Q-W2v below.**
|
||
|
||
## Q-W1 — safe opener: extract `core/json` + impose the directory/namespace layout on clean modules
|
||
|
||
> **Landed on `phase-q` (2026-07-29). Integrated suite 60/60 green.** `core/json`
|
||
> (`json::Reader`/`json::Writer`) extracted; the five hand-rolled JSON decoders (incl.
|
||
> `tail_control`'s) deleted; the wire-`Cursor` family collapsed into `core/wire`; the shared
|
||
> `readFileBytes` helper added; ~50 clean modules relocated into `core/{model,view,capture,
|
||
> audio,ui,reclaim,version,json,util,wire}/`, `core/instrument/{engine,map,ui}/`,
|
||
> `shell/{capture,panel,view,persist,actions,instrument}/`, `app/main.cpp`; sub-namespaces
|
||
> applied; one concrete `ui::Rect` + aliases (LTRB fork + `footer_bar` NAME NOTE retired);
|
||
> `slot_map` extracted from `bank_book`; `clamp01` deduped; `BankIndex`→`BankModel`;
|
||
> `reasampler_uid.h` relocated to `core/wire/`. See `COMPLETED.md` for the full narrative.
|
||

|
||
> **Skipped/deferred riders:** T4-22 (`hitIndex` hit-test template) — not trivial, deferred as
|

|
||
> (`view_mode_model` planner split) — optional, deferred; T4-09 (`view_lanes` split) —
|
||
> deferred (in scope only if a later wave touches `view.cpp` anyway).
|
||
>
|
||
> **Open residual — `bank_book.cpp` still 737 LOC.** The serialize/deserialize seam is
|
||
> identified but blocked on a `nameKey` linkage design decision, escalated to Daniel and
|
||
> **pending** as of 2026-07-29. Downstream waves touching `bank_book` should check this
|
||

|
||
>
|
||
> An interim `core/namespaces.h` shim covers the six not-yet-split god TUs; each downstream
|
||
> split wave (Q-W2 onward) retires its own includes of it as that module splits.
|
||
|
||
## Q-W2 — split `bank_panel.cpp` (the biggest extension god-module — 3459 LOC at the Q-W0 census)
|
||
|
||
> **Landed on `phase-q` (2026-07-29, merge of `pq-w2-panel`). Integrated suite 61/61 green,
|
||
> reviewed-approved.** `bank_panel.cpp` (3459 LOC) split into eight TUs under `shell/panel/`:
|
||
> `panel_render` / `panel_thumbnails` / `panel_audition` / `panel_input` / `panel_bank_ops` /
|
||
> `panel_window` / `panel_layout` / `panel_drag`, plus per-seam public headers and internal
|
||
> `panel_state.h`; audition stays a direct call-through; the one-bank-op-one-undo invariant is
|
||
> preserved; ~50 TU-private helpers wrapped in anonymous namespaces (a review follow-up). See
|
||
> `COMPLETED.md` for the full narrative.
|
||
>
|
||
> **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 — the 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
|
||
> `actions.cpp` and are the cheapest first dedupe.
|
||
>
|
||
> **In-DAW verification (panel parity) is PENDING on `phase-q`** — deferred by design, not yet
|
||
> performed.
|
||
|
||
## Q-W2v — split the VST god-modules (NEW wave — Q-W0 T4 §1.5; runs parallel with Q-W2)
|
||
|
||
> **Landed on `phase-q` (2026-07-29, merge of `pq-w2v-vst`). Integrated suite 61/61 green,
|
||
> reviewed-approved.** `reasampler_editor.cpp` (3084 LOC, the largest file in the repo) split
|
||
> into eight face-axis TUs under `shell/instrument/`, with pure layout hoisted into
|
||
> `core/instrument/ui/editor_geometry` (discharges T2-06, newly tested); `reasampler_processor.cpp`
|
||
> split into `processor_state` / `processor_reload` / lifecycle+`process()` kept whole (no
|
||
> virtual seam, T4-29); `sample_map` split into a resolution core + `component_state_io` codec
|
||
> (the extension preset path no longer links the voice engine — link-proven; T4-13 ≡ T2-07);
|
||
> `sampler_core.cpp` stays whole with the documented hot-path exception comment (T4-14/T4-27);
|
||
> `zone_params.h` split out; `core/wire/bytes.h` (`putLE`/`ByteReader`) lands (T4-20);
|
||
> `ThumbnailKey` adopted (T2-10); a golden full-blob v11 fixture pins the codec bytes. The
|
||
> `src/vst/` directory is gone. See `COMPLETED.md` for the full narrative.
|
||
>
|
||
> **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.
|
||
>
|
||
> **In-DAW verification (editor/processor parity) is PENDING on `phase-q`** — deferred by
|
||
> design, not yet performed.
|
||
|
||
## Q-W3 — split `main.cpp` (hoist orchestration; leave main = pointers + entry + dispatch)
|
||
|
||
> **Landed on `phase-q` (2026-07-29, merge of `pq-w3-main`). Integrated suite 61/61 green,
|
||
> reviewed-approved.** `app/main.cpp` reduced 1897 → 653 LOC (pointers + entry + dispatch; the
|
||
> remaining bulk is the registration residue Q-W6 dissolves) via four hoists into
|
||
> `shell/capture/`: `capture_orchestrator`, `capture_batch`, `scope_resolve`,
|
||
> `realtime_lifecycle`; `FxBypassGuard` moved intact as a stack RAII object; the realtime idle
|
||
> tick stays a single pointer test; `ICaptureBackend` deleted (T4-26) with the
|
||
> CLAUDE.md/CONTEXT-ARCHIVE corrections landed in the same commit; the Q-9 rename done (pure
|
||
> `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

|
||
|
||
## 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 —
|
||
T4-03: the planned seams still land sub-600, no reshape) into
|
||
`design_view_actions` / `bank_actions` / `prune_action`, and **dedupe** `actions.cpp`'s own
|
||
`promptText`/`mintBankId` and bank verbs against the `panel_bank_ops` single-owner established in
|
||
Q-W2. `prune_action` keeps the `doBankPruneFolder` deletion authority contract intact (routes to
|
||
`persist`'s `prune_fs` after W5). CONTEXT.md §Phase Q (actions split seams; bank-verb dedupe).
|
||
See `docs/product/code-organization.md` §2.1, §2.4.
|
||
**Verify:** CTest green at every commit. Every action fires identically in DAW (Design View
|
||
family; multi-bank create/rename/reorder/delete/evacuate/activate/move/copy/remove; prune). The
|
||
bank-CRUD verbs have **one** implementation home (no `bank_panel`/`actions` duplication). Each
|
||
bank verb still wraps its mutation in one batched undo point; the prune action still writes no
|
||
ext state and opens no undo point. Command-id strings are **unchanged** (FOREVER-STABLE
|
||
contract — a reorg must not touch a shipped command id).
|
||
**Depends on:** Q-W2 (`panel_bank_ops` is the dedupe target). Independent of Q-W3.
|
||
|
||
- [ ] Split → `design_view_actions` (toggle/activate/tag/untag/showBoth/moveItems),
|
||
`bank_actions` (bank CRUD family), `prune_action` (`doBankPruneFolder` — the single
|
||
file-deletion action).
|
||
- [ ] Dedupe `actions.cpp`'s `promptText`/`mintBankId` + bank verbs against `panel_bank_ops`
|
||
(one owner); do **not** change any command-id string.
|
||
- [ ] Verify in DAW: all action families fire unchanged; one bank op = one Ctrl-Z; prune still
|
||
no-undo/no-ext-state; CTest green.
|
||
|
||
## Q-W5 — split `persist.cpp` (isolate the single file-deletion authority into `prune_fs`)
|
||
**Goal:** Split `persist.cpp` (852 LOC at the Q-W0 census — T4-04: seams unchanged; the
|
||
pS-usage growth landed exactly where this wave isolates it; 5 responsibilities) into `session`
|
||
(lifecycle+poll, `BeginLoadProjectState` reload hook), `ext_state_io` (the ext-state ↔ JSON
|
||
serialization bridge + GUID minting + folder relocation), and **`prune_fs`** (prune scanning +
|
||
`deleteOrphanFile` via `SHFileOperationW`). The split **concentrates** the byte-deleting
|
||
authority into one obvious module — it must never spread it. **Q-W0 rider (T2-04, SETTLED
|
||
2026-07-28):** generalize the `GetProjExtState` grow-loop retry policy into `bridge_marshal`'s
|
||
pure decode home (or its `core/` successor) and rewire all three hand-rolled copies —
|
||
`usage_scan`'s prune-safety-adjacent copy included. CONTEXT.md §Phase Q (persist split seams;
|
||
deletion-authority isolation). See `docs/product/code-organization.md` §2.1, §7.
|
||
**Verify:** CTest green at every commit. Session save/load/undo-reload, ext-state round-trip,
|
||
folder relocation, and prune deletion all behave identically in DAW. **File deletion lives in
|
||
exactly one module (`prune_fs`)** — the single-file-deletion-authority invariant is *improved*
|
||
(concentrated), never diluted. Relative-paths-only persistence is unchanged.
|
||
**Depends on:** Q-W1. Best after Q-W4 (so `prune_action` routes cleanly to `prune_fs`), but
|
||
independently landable.
|
||
|
||
- [ ] Split → `session` (lifecycle/poll + `projectconfig` reload hook), `ext_state_io`
|
||
(serialization bridge + GUID minting + folder relocation).
|
||
- [ ] Isolate prune scanning + `deleteOrphanFile` (`SHFileOperationW`) → **`prune_fs`** — the
|
||
one file-deletion module; nothing else may delete bytes.
|
||
- [ ] Dedupe the `GetProjExtState` grow-loop ×3 (T2-04): one retry policy generalized from
|
||
`bridge_marshal`; rewire `usage_scan`'s prune-safety-adjacent copy with `sample_usage_tests`
|
||
green.
|
||
- [ ] Verify in DAW: save/load/undo-reload/relocation/prune unchanged; deletion authority is one
|
||
module; relative-paths-only holds; CTest green.
|
||
|
||
## Q-W6 — OCP registration-table + residual fat-header (I) splits
|
||
**Goal:** Close the last SOLID wart: replace the ~350-line hand-written **non-table** action
|
||
registration blocks (now isolated in `app/main.cpp` after Q-W3) with a **registration table**, so
|
||
adding an action edits one place, not four parallel ones (OCP). Split any remaining fat headers
|
||
(`capture.h`/`persist.h`) not already resolved by their TU splits (I). (Q-W0: no reshape —
|
||
T4-02 notes the ~385-line registration residue left in `app/main.cpp` after Q-W3 shrinks
|
||
further under the table.) CONTEXT.md §Phase Q (OCP
|
||
registration-table). See `docs/product/code-organization.md` §2.3, §6 (Q-6).
|
||
**Verify:** CTest green at every commit. Every action still registers, appears in the Actions
|
||
list, and fires via `hookcommand` exactly as before; command-id + display strings unchanged
|
||
(FOREVER-STABLE, per-channel); unload still mirror-unregisters everything. Adding a hypothetical
|
||
new action now touches the table only (demonstrated in review, not shipped). Remaining fat
|
||
headers are segmented.
|
||
**Depends on:** Q-W3 (registration code must be isolated first). Sequenced last; the most
|
||
droppable point if the phase needs narrowing (Q-6).
|
||
|
||
- [ ] Convert the hand-written `Register("command_id"/"gaccel"/"hookcommand")` blocks to a
|
||
data-driven registration table; unload mirror-unregisters from the same table.
|
||
- [ ] Split residual fat headers (`capture.h`/`persist.h` and any other) alongside their TUs (I).
|
||
- [ ] Verify: all actions register/fire/unregister unchanged; command-id strings untouched; CTest
|
||
green.

|
||
Q-W0 has run and is signed off (2026-07-28); its sub-gate closes when the six fix-now
|
||
remediations land. W1 is the safe, high-leverage structural opener (all later waves assume the
|
||
layout — including the T4-18 `instrument/` placement — it establishes). The god-module splits
|
||
(W2, W2v, W3, W5) are risk-ordered and mostly parallel-safe; **Q-W2v runs parallel with Q-W2**
|
||
(different artifact, zero file overlap — audit §4f SETTLED); W4 depends on W2's
|
||
`panel_bank_ops`, W6 depends on W3's isolated registration code. Big-bang is rejected — every
|
||
wave is independently landable and CTest-green.
|
||
|
||
## Phase Q — must-verify-before-build
|
||
- **Q-W0 closed before any structural point** — the functional/DSP audit's findings report exists,
|
||
every finding is triaged (fix-now vs. document-and-defer, each with rationale), fix-now findings
|
||
are remediated or assigned to the wave that opens their file, and **Daniel has signed off on every
|
||
disposition.** Q-W1 does not begin otherwise. (CONTEXT.md §Phase Q Q-W0; naming/DSP smell
|
||
categories §2c of `docs/product/code-organization.md`.) **Status 2026-07-28: triage + sign-off
|
||
COMPLETE (all 59 dispositions); the sub-gate closes when the six fix-now remediations land
|
||
(`pq-w0-fixes`).**
|
||
- **~600-line ceiling on every split wave** — every TU a split wave ships lands under ~600 LOC,
|
||
with `sampler_core.cpp` the single documented exception (T4-14/T4-27). Seams are the method,
|
||
the ceiling is the bar; arbitrary bisection to hit the number is rejected (Q-5 settlement,
|
||
2026-07-28).
|
||
- **No dispatch-stack blowouts anywhere** — heuristic (3) generalizes the hot-path guardrail
|
||
beyond the three named paths: prefer static polymorphism where types are compile-time-known;
|
||
templates only where earned for compile-time dedup (T4-20 yes; T4-21's rect NO-template
|
||
ruling).
|
||
- **Hot-path call/inline shape** — before landing each split, confirm no virtual dispatch and no
|
||
header→TU indirection was added on `peaks` envelope compute, audition/preview, or the realtime
|
||
tick. `computeEnvelope` stays a free function on `const std::vector<float>&`;
|
||
audition stays a direct call-through; the idle tick stays a single pointer test. (CONTEXT.md
|
||
§Phase Q, `docs/product/code-organization.md` §3.)
|
||
- **Command-id + display strings are FOREVER-STABLE** — a reorg must not change a shipped
|
||
`command_id` string, action display name, ext-state namespace, or VST3 class UID. Re-namespacing
|
||
C++ symbols is orthogonal to these on-the-wire/on-disk contract strings; keep them byte-identical
|
||
(per-channel, per the Phase V V4 contract). (CONTEXT.md §Phase Q.)
|
||
- **Name-collision sweep on sub-namespacing** — `Sample` (model) vs `AudioSample` (audio) vs the
|
||
unified `Parser` (json), plus the shared pure-UI rect types `FooterRect`/`ButtonRect` (already
|
||
hand-collision-checked in `footer_bar.h`), and any other cross-lib name that collides once
|
||
flattened into granular namespaces. Resolve by each symbol's new subsystem home before landing
|
||
W1. (naming audit §2b.2; `docs/product/code-organization.md` §6 Q-4/Q-8.)
|
||
- **Naming stays zero-behavior-change and off the wire** — the §2b renames touch C++ symbols only;
|
||
no `command_id` string, action display name, ext-state namespace/key, `reasampler:` lane prefix,
|
||
or VST3 class UID is renamed (naming audit §2b.5). A rename that would alter a shipped contract
|
||
literal is out of scope, full stop.
|
||
- **The GATE** — do not begin any Q point until **Phase S + Phase L L3** are merged to dev and the
|
||
tree is quiescent (D2 complete, M9 abandoned). Re-confirm quiescence against dev before W1.
