# authoritative verbatim — leading zero preserved (Daniel-fixed: exactly "0.9.01",
# two-digit zero-padded patch). We deliberately do NOT reconstruct the display string
# from project(VERSION)'s numeric components, since CMake may normalize a numeric patch
# field; the string variable is what renders. project(VERSION ...) is still set (with a

# ext-state namespace, command-id strings, version render); `beta` = a fully isolated
# `reaper_reasampler_beta` that coexists with stable in one REAPER. The flag reduces to
# ONE bit (REASAMPLER_CHANNEL_IS_BETA) threaded through the SAME configure_file'd header
# as the version string, so the pure app_version module derives every channel-qualified
# identity from it — no scattered #ifdefs. Any value other than exactly `beta` is treated
# as stable (a typo must not silently produce a half-forked build), and we hard-error on
# an unrecognized non-empty value so a misspelled `-DREASAMPLER_CHANNEL=betaa` is caught

#       detection core: current \ previous GUID diff + the first-poll-after-open
#       baseline guard (and per-project reset). Split out so the fiddly baseline/diff
#       logic is unit-tested outside the DAW; the bank_panel timer that reads REAPER's

# 2d''') Pure lane_keys library — NO REAPER, NO SWELL. The managed/manual fixed-lane
#        heuristic (D2 Wave-2): a lane whose durable P_LANENAME:n carries the
#        "reasampler:" prefix is tool-managed and keyed by that stable name; any other

# 2e) Pure insert_plan library — NO REAPER, NO SWELL. The InsertMedia `mode`
#     bitmask arithmetic behind the `insert` shell (M6). Split out so the

# 2f'') Pure batch_capture library — NO REAPER, NO SWELL. The M11 batch-capture
#       logic: an ordered list of source ranges (one per selected item / per razor
#       area) -> validated, ordinal-assigned capture units (empty/inverted dropped),
#       plus order-preserving per-unit result aggregation into a mixed-result summary
#       line. Split out so the plan/aggregate/summary is unit-tested outside the DAW;
#       the selection read, transient re-selection, and render loop stay in main.cpp.

#      tail-mode toggle logic (T1 exposure): TailSetting state, cycle order
#      (None->Auto->Manual->None), the manual-length clamp to the 8 s cap, and the
#      toggle label text. Split out so the toggle's cycle/clamp/label is unit-tested
#      outside the DAW; the bank_panel footer that draws it + routes clicks is

# ---------------------------------------------------------------------------
# 2g') Pure bank_book library — NO REAPER, NO SWELL. The multi-bank phase heart
#      (Phase B1): an ordered registry of banks (pool seeded as bank-zero + named
#      banks), each wrapping a BankIndex; create/rename/reorder/delete named banks,
#      pool privileges enforced in-model, active-bank id, index-only move/copy of a
#      sample between banks, JSON round-trip + legacy-bank_index→pool migration.

# 2g'') Pure owned_manifest library — NO REAPER, NO SWELL. The owned-file manifest
#       seam (Phase B B-cap): the set of project-relative files the capture path
#       itself created, so Phase R prune can tell the bank system's own orphans from
#       hand-dropped files. Deliberately DECOUPLED from bank_book — it tracks files
#       CREATED, not index membership (sample-remove is not manifest-remove). Small
#       pure type + JSON round-trip; mirror of wav_trim / tab_strip. B-cap writes +
#       persists it; Phase R (R1/R2) consumes it — no prune logic here.

# 2g''') Pure prune_reconcile library — NO REAPER, NO SWELL, NO filesystem. The
#        Phase R (Reclaim) Wave-1 safety-critical decision: given the files present
#        in the bank folder, the union of files referenced across every bank, and the
#        owned-file manifest, compute the orphan set (owned ∩ present) − referenced.
#        Mirror of view_mode_model::reconcile one level down (files, not GUIDs). Small
#        pure function; R2/R3 wrap the two ends (folder enumeration + deletion) in the

# 2g'''') Pure prune_button layout — NO REAPER, NO SWELL. The Phase R (Reclaim)
#         Wave-3 (R3, fork R-E) prune-button geometry: footer rect -> right-anchored
#         button rect (suppressed when the footer is too narrow), and point -> in/out
#         hit-test. Split out so the button's placement + hit-test math is unit-tested
#         outside the DAW; the bank_panel footer that draws it and dispatches the

# 2g) Pure realtime_record library — NO REAPER, NO SWELL. The M8 realtime-record
#     logic: capture scope + FX-tap point -> I_RECMODE / I_RECMODE_FLAGS values,
#     wet/dry -> tap point, and the recorded-file -> Sample mapping. Split out so
#     the fiddly record-mode bit values + Sample population are unit-tested outside
#     the DAW; the transport/temp-track/send/file-move recipe stays in capture.cpp.
#     Depends on bank_model for the pure Sample / SourceMode types.

# 2h) Pure wav_trim library — NO REAPER, NO SWELL. The realtime tail's (T2) PCM
#     decay-scan trim needs to TRUNCATE the recorded 32-bit-float WAV at a frame
#     boundary without corrupting the RIFF container. This module holds the fiddly,
#     easy-to-get-wrong part unit-tested outside the DAW: parse the WAV geometry
#     (fmt/data chunk walk + 32-bit-float verification), extract the tail-region
#     floats to scan, and compute the truncate plan (kept byte length + the two
#     patched RIFF/data size fields). The file read/write/truncate I/O stays in the
#     realtime shell. Depends on peaks for the AudioSample float alias.

# ---------------------------------------------------------------------------
# 2i) Pure app_version library — NO REAPER, NO SWELL. The Phase V (V1) version-identity
#     core: re-exports the ONE CMake-sourced version string (via the configure_file'd
#     version_generated.h) and owns the pure parse/compare/classify logic — the semver
#     ordering a within-channel forward migration needs, and the three-way writing-version
#     classification (PreVersioning / Unknown / Stamped) persist reads back from ext state.
#     Split out so the exact-string fidelity + parse/compare are unit-tested outside the
#     DAW; the ext-state write/read (persist) and the show-version action (main) are shell.
#     Depends on the generated header in the build tree (PUBLIC so every consumer sees it).

target_include_directories(app_version PUBLIC src ${CMAKE_CURRENT_BINARY_DIR}/generated)

# ---------------------------------------------------------------------------
# 2j) Pure provenance library — NO REAPER, NO SWELL. The Milestone 10 core: the
#     recorded capture recipe (CaptureRecipe) + the thin drift-fingerprint that
#     rides in Provenance.fxChainSnapshot (P1=a), its build/parse round-trip, the
#     FX-chain identity fold, and the pure parent-detection decision (resample-from-
#     sample by resolved file path). Split out so the encoding + decision logic are
#     unit-tested outside the DAW; the FX-chain query, capture re-run, and action
#     registration stay in the shell (main.cpp / actions.cpp). No dependency on
#     bank_model — it takes plain strings/values at its boundary.

add_library(provenance STATIC src/provenance.cpp)
target_include_directories(provenance PUBLIC src)

# ---------------------------------------------------------------------------
# 2j') Pure assignment_request library — NO REAPER, NO SWELL, NO VST3. The S8 ingest
#      assignment-request wire format: the (bankId, sampleId, generation) value the
#      EXTENSION writes to "reasampler" ext-state after an ingest-with-assign, decoded by
#      the VST3 instrument in a later dispatch. Only the wire (build/parse round-trip)
#      lives here — writing it is the persist shell's job, reading it the instrument's.
#      Split out (mirror of provenance / owned_manifest) so the format both artifacts
#      depend on is unit-tested outside the DAW; the reader lands in a separate artifact,
#      so the round-trip test is the contract guard. No dependency — plain strings + int64.

target_include_directories(assignment_request PUBLIC src)

# ---------------------------------------------------------------------------
# 2k) Pure action_buttons library — NO REAPER, NO SWELL. The Milestone 11
#     action-trigger button strip: strip rect + N buttons at a minimum width ->
#     per-button rects (equal tiling; overflow HIDES excess on a narrow panel
#     rather than clipping), point -> button hit-test, and the button label format
#     (action name + SDK binding string -> label, with the unbound/blank case
#     degraded to an explicit marker and an over-long binding truncated). Split out
#     so the layout + label math is unit-tested outside the DAW; the bank_panel
#     draw + NamedCommandLookup/Main_OnCommand dispatch + kbd_getTextFromCmd query

# 2l) Pure drag_out library — NO REAPER, NO SWELL, NO OS/OLE. The Milestone 11
#     native-OS-drag-out decision core: the gesture-boundary decision (drag state +
#     pointer + panel rect -> internal drag / OS drag / none — the invariant-#4 seam
#     that keeps the internal bank-to-bank drag byte-identical) and the drag path-list
#     assembly (resolved sample paths -> de-duped, existing-only absolute path list with
#     an explicit skip-missing / skip-unresolved policy). Split out so the boundary +
#     set algebra are unit-tested outside the DAW; the OLE DoDragDrop / SWELL file-list

# 2l') Pure instrument_drop library — NO REAPER, NO SWELL, NO VST3 SDK. The S17
#      drop-and-load blob-construction core: turn the dragged capture id into the
#      base64 "vst_chunk" the extension injects via TrackFX_SetNamedConfigParm so a
#      freshly-added ReaSampler 9000 plays that capture. Reuses the instrument's OWN
#      serializer (sample_map::serializeComponentState) — NOT a parallel byte writer —
#      so the cross-artifact blob contract cannot drift; links sample_map (which pulls
#      bank_book/wav_trim/sampler_core transitively) and NEITHER SDK. The round-trip
#      test decodes back through the instrument's own reader. Mirror of assignment_request.

# 2m) Pure theme library — NO REAPER, NO SWELL, NO LICE. The Phase L (L1) palette
#     core of the shared drawing kit: a ROLE-based color model (bg/base..warn), the
#     interaction-state transform (rest/hover/active/pressed/dragging/focus/disabled),
#     the Direction C spectral hue ramp, and the WCAG contrast math that lets a unit
#     test prove every text-on-surface pair clears its floor ("punch to the floor").
#     THE SINGLE POINT OF CHANGE (DS-2): one direction constants block feeds roleColor;
#     switching the visual direction is a one-file edit. The draw shell (draw_kit) turns
#     a KitColor into a LICE_pixel at the boundary. Mirror of mode_switch — pure.

# 2n) Pure component_geometry library — NO REAPER, NO SWELL, NO LICE. The Phase L (L1)
#     generic component geometry the kit draws against: button box (inset + graceful
#     suppression), horizontal slider track/handle/filled geometry + value<->px inverse,
#     and list-row rect + hover hit-test. The kit-level primitives that don't already
#     have a pure owner (bank_grid/mode_switch/tab_strip/action_buttons/prune_button
#     stay the source of truth for THEIR surfaces). Names KitBox/KitButtonBox/

# 2o) Pure action_bar library — NO REAPER, NO SWELL, NO LICE. The Phase L (L2)
#     dock-panel layout redesign core: the TASK-GROUPED action bar geometry that
#     supersedes the flat M11 action_buttons strip for the panel's action inventory —
#     clusters (capture / placement / maintenance) tile the bar at a fixed button
#     width with intra/inter-cluster gaps, each button carrying a label + keybinding
#     micro sub-rect, whole trailing buttons dropped (never clipped) on a narrow panel,
#     and point -> flat action index hit-test. Split out so the layout + hit-test math
#     is unit-tested outside the DAW; the bank_panel L1-kit draw + NamedCommandLookup/

# 2p) Pure footer_bar layout — NO REAPER, NO SWELL, NO LICE. The Phase L (L4)
#     dock-panel button-layout enhancement's footer LEFT group: the narrowed
#     [Arrange|Design] mode toggle, its compact per-mode count label, and the Tail
#     button, laid out left-to-right with greedy right-reserve suppression (the RIGHT
#     Prune button stays owned by prune_button). Point -> Toggle/Tail/None hit-test.
#     Split out so the footer's new multi-affordance row math is unit-tested outside
#     the DAW; the bank_panel L1-kit draw + tail-cycle/mode-activate dispatch are

#     the action_bar must leave for it, and point -> in/out hit-test. Split out so the

#     clickable. Split out so both active modes are covered by CTest (not only whichever a
#     DAW pass sat in); the bank_panel reads the active mode from view().activeModeId() and

#     bounded stealing, an ADSR amplitude envelope, a key/velocity keymap with
#     (note, velocity) -> zone resolution, and repitch/interpolation from a root note
#     with loop-point-aware sustain. The mirror of bank_model / peaks / bank_book,
#     tested hard outside any host. Lives under src/vst/ (it is instrument code) but
#     links NEITHER SDK — the plain-data boundary is enforced structurally: the test
#     target below links only sampler_core (+ its peaks dep for the AudioSample alias,

# Windows-only, VST3-only, REAPER-only (D5). A separate native VST3 plugin the user
# instantiates on an instrument track. Additive: the reaper_reasampler target above
# builds unchanged. This is the S1 opening spike — a silent-but-loading
# SingleComponentEffect skeleton, an IPlugView<->LICE editor, and the REAPER VST-host
# bridge read — not yet a sampler.
#
# ONE-TIME SDK SUBMODULE SETUP (see README / .gitmodules): the vst3sdk superproject is
# vendored pinned to tag v3.7.9_build_61; only three of its sub-submodules are needed
# (VSTGUI/examples/tests are NOT). After `git submodule update --init vendor/vst3sdk`:
#     cd vendor/vst3sdk && git submodule update --init pluginterfaces base public.sdk
# ===========================================================================

# fail configure on missing sources: the pure geometry/mapping libraries + their CTest

    # bank_sync (S9/S8 reader): the pure generation-compare + assignment-consume decision the
    # processor's off-thread poll runs; links assignment_request transitively (the decoded
    # request it consumes) — the same key the extension writes, shared via the pure module.
