Move completed M3 (offline capture spike) from PLAN.md to COMPLETED.md; close the render-command and bank-format open questions; add capture_paths_tests to the CLAUDE.md targets table and note M8 is dialog-free.

# COMPLETED.md — ReaSampler landed milestones
|
|
|
|
Completed milestone entries removed from `PLAN.md`. Each entry preserves its
|
|
original Goal, Verify, and checklist points with boxes marked done.
|
|
|
|
---
|
|
|
|
## Milestone 0 — Transition scaffold: reaper_mpeview → ReaSampler
|
|
**Goal:** Retire the MPE scaffold and stand up the sampler's pure core in its
|
|
place, preserving the pure-core / REAPER-shell split.
|
|
**Verify:** `cmake -B build -S .` configures clean; `cmake --build build` builds
|
|
the renamed extension target and the pure-core test target; `ctest --test-dir
|
|
build` is green with the new `bank_model` + `peaks` suites present.
|
|
|
|
- [x] Delete `src/mpe_model.{h,cpp}` and `src/mpe_view.{h,cpp}`; remove
|
|
`tests/test_mpe_model.cpp`.
|
|
- [x] Rename the CMake `project()` and the extension MODULE target from
|
|
`reaper_mpeview` to `reaper_reasampler` (binary `OUTPUT_NAME` likewise);
|
|
update `PREFIX ""` / platform SUFFIX blocks to the new target name.
|
|
- [x] Replace the pure `mpe_model` static lib + `mpe_model_tests` executable with
|
|
`bank_model` (pure static lib) + `bank_model_tests`; keep the CTest wiring.
|
|
- [x] Repoint `src/main.cpp`: drop the `mpe_view.h` include and all `MpeView_*`
|
|
calls (toggle / IsOpen / OnTimer / Cleanup); stub the extension entry so it
|
|
loads, logs to console, and registers nothing MPE-specific. The
|
|
`command_id` / `gaccel` / `hookcommand` registration *pattern* is preserved for
|
|
reuse (CLAUDE.md §REAPER extension contract) — the MPE action string is removed.
|
|
- [x] Choose and record the persistent action-id prefix for the sampler family
|
|
(replaces `CEREBELLUM_MPEVIEW_TOGGLE`); this string is forever-stable once
|
|
shipped (CLAUDE.md §action registration).
|
|
- [x] Refresh `README.md` layout/next-step sections to the sampler module set.
|
|
(Landed-work reflection is doc-keeper's; this point exists so the stale MPE
|
|
README does not mislead the first implementer.)
|

## Milestone 1 — bank_model + JSON round-trip (pure)
|
|
**Goal:** The `Sample` metadata struct and `BankIndex` (add / remove / query /
|
|
tier moves / dedup-by-hash) with JSON serialize/deserialize to `std::string`.
|
|
CONTEXT.md §Data model, §Module architecture.
|
|
**Verify:** CTest green. Round-trip is lossless (deserialize(serialize(x)) == x)
|
|
across all fields; dedup-by-hash and tier filtering asserted; **relative paths
|
|
only** invariant enforced at the model boundary (no absolute path accepted/stored).
|
|
|
|
- [x] Define `Sample` with the full field set (id, display name, relative path,
|
|
source mode, source range in project time + PPQ, track GUID(s), wet/dry,
|
|
channels, SR, length sec + beats, capture tempo, optional key, peak/RMS/LUFS,
|
|
clip flag, tier, content hash, provenance, created ts). CONTEXT.md §Data model.
|
|
- [x] `BankIndex`: ordered collection keyed by id; add / remove / query.
|
|
- [x] Hash lookup for dedup-by-content-hash.
|
|
- [x] Tier model (scratch | archive) + tier-move + tier filtering; scratch marked
|
|
auto-prunable.
|
|
- [x] JSON serialize/deserialize to/from `std::string`.
|
|
- [x] Tests: full-field round-trip lossless; dedup collapses equal-hash adds;
|
|
tier filter/move correct; relative-path invariant rejects absolute paths;
|
|
empty-index and malformed-JSON edge cases.
|
|

|
## Milestone 2 — peaks (pure)
|
|
**Goal:** Compute waveform min/max bins from raw PCM, dependency-free (not
|
|
REAPER's peak API). CONTEXT.md §Module architecture, §Non-goals.
|
|
**Verify:** CTest green. Fed a known signal (full-scale sine, ramp), asserted
|
|
min/max envelope per bin matches expected within tolerance; channel count
|
|
preserved; bin count honored for arbitrary sample lengths (incl. remainder bin).
|
|
|
|
- [x] Min/max bin computation from interleaved PCM given a target bin count.
|
|
- [x] Multi-channel handling (per-channel envelope; no silent fold).
|
|
- [x] Tests: sine envelope ≈ ±amplitude; ramp envelope monotonic; DC/silence →
|
|
zero envelope; short-buffer and non-divisible-length edge cases.
|

## Milestone 3 — Offline capture spike (REAPER shell)
|
|
**Goal:** Offline-render the time-selection master mix to a wav in the project
|
|
bank folder, add a `Sample`, log it. The render-driving spike. CONTEXT.md
|
|
§REAPER API surface (offline render), Build order 3.
|
|
**Verify (in DAW):** Render runs via `Main_OnCommand(42230)` ("Render using most
|
|
recent settings") — REAPER always shows its offline-render progress window; no
|
|
stock/header-documented fully-headless path exists. File lands in the
|
|
project-relative bank folder at **32-bit float WAV** at project rate (lossless,
|
|
dither-free → enables bit-identical/null-test). A `Sample` is added to the
|
|
in-memory `BankIndex`. Non-destructive. Unsaved-project state triggers a
|
|
Save-As prompt; capture is refused if the user cancels (no default-location
|
|
fallback).
|
|
**Bit-identical repeats:** two identical requests produce byte-identical files.
|
|
**Exact bounds:** rendered length matches the requested range (no rounding, no
|
|
added silence without an explicit tail).
|
|
|
|
- [x] `ICaptureBackend` interface + `CaptureRequest` (source mode, time range,
|
|
wet/dry, tail, SR/bit-depth/channels, output path). CONTEXT.md §capture.
|
|
- [x] `OfflineRenderBackend`: drive `GetSetProjectInfo` render settings +
|
|
`GetSetProjectInfo_String` file/pattern/format; **verify every flag against
|
|
`vendor/reaper-sdk/sdk/reaper_plugin_functions.h`.**
|
|
- [x] Resolve the no-dialog render command/flag on the current REAPER build
|
|
(open question) and confirm it runs headless.
|
|
- [x] Populate a `Sample` from the finished file; hand to `bank_model`; console-log.
|
|
- [x] Verify bit-identical repeats and exact-bounds by hand on a known range.
