Mike-Solar 4babbf5de8 core: merge oak-common into oak-core
CI / Build & test (Linux) (push) Successful in 24m6s
CI / Build & test (Windows) (push) Successful in 31m14s
oak-common is gone; its modules (configstore, xmlutils, ocioutils,
oiioutils, colormath, colortransform, videoparams, ffmpegutils, ...)
now live in oak-core alongside the value types. The render value/GPU
types moved too: backend (wgpu context + DisplayRenderer), color
(ColorProcessor over ocio-rs), texture, frame, and the commonutil
config helpers.

Fix-ups to make the merged tree build and pass tests:

- oak-core Cargo.toml: wgpu back to 25 (the moved backend code is
  written against that API generation); add the toml/quick-xml/image
  deps oak-common carried.
- lib.rs: drop the duplicate 'pub mod error;'.
- error.rs: unified OAKCORE_* codes; restore Error::new() and
  From<OcioError> from oak-common's error type.
- backend.rs/color.rs: oak_core::/oak_render:: self-references
  rewritten to crate::; the shaderfx-dependent GPU effect test moved
  to oak-render's shaderfx tests (shaderfx depends on oak-node and
  cannot live in oak-core).
- oak-render's error module re-exports oak_core::error::{Error,
  Result}; the OAKRENDER_* codes stay as the public-code contract.
- oak-node jobs.rs: ColorProcessor imported from oak_core::color.
- Integration tests repointed at oak_core::{texture, frame, backend,
  color, colormath}.
- the display-ICC regression test treats an empty OAK_DISPLAY_ICC as
  unset, matching displayicc::env_override_icc.

Mike-Solar 71bc748d98 build: point ocio-sys at the fork carrying the zlib-ng detection fix
The vendored minizip-ng prefers find_package(ZLIBNG) over the classic
zlib the OCIO install scripts pass, so hosts with zlib-ng installed
(Arch) produced zng_* references the vendored zlib cannot satisfy and
the final link failed. Mike-Solar/ocio-rs@ddb677d disables the ZLIBNG
package lookup; the fork main now carries that plus the cstdint fix.

Mike-Solar 8bf3f1e2df ci/cd: vendored static OCIO everywhere, ocio-sys tracks upstream main
Policy change (supersedes the system-first probe): build OpenColorIO
from the vendored sources and link it statically on every platform
that can -- packaged binaries carry no OCIO runtime dependency. The
[patch.crates-io] ocio-sys now tracks shaloong/ocio-rs main
explicitly; its vendored yaml-cpp has the <cstdint> include that makes
the vendored build work on GCC >= 16 (verified on GCC 16.2.1).

Windows/MinGW stays the exception (the vendored source needs MSVC-only
constructs): tooling/ocio-env.sh probes the MSYS2 system OCIO there,
static when libOpenColorIO.a ships, dynamic otherwise. The Linux jobs
drop the system OCIO dev packages the system-first policy needed.

Mike-Solar 5b38d07299 ci/cd: NVDEC-capable FFmpeg, GCC16-proof OCIO, system-first OCIO env
- Install ffnvcodec headers everywhere the project FFmpeg is built
  (distro packages on Debian/Ubuntu/Arch/MSYS2, nv-codec-headers from
  source on Fedora) so the FFmpeg build picks up NVDEC/NVENC.
- ocio-sys 0.2.1's vendored yaml-cpp misses <cstdint> and fails on
  GCC >= 16 (measured on GCC 16.2.1); patch the dependency to the
  fixed upstream tree (shaloong/ocio-rs, 933c65dc) until a fixed
  release lands on crates.io.
- New tooling/ocio-env.sh decides the OCIO build env per job: system
  OCIO >= 2.5 when present (static when the package ships
  libOpenColorIO.a, dynamic otherwise), vendored static build as the
  fallback. The Arch package gains an 'opencolorio' dependency only
  when the binaries link the system OCIO (build-pkg.sh probes ldd).
- CI 'Build' steps switch from cargo build to cargo check: the Test
  step links the test binaries anyway, and a full build would codegen
  every workspace crate twice.

Mike-Solar d2ac02a474 build: relax the ocio-rs constraint to 0.2
CI / Build & test (Linux) (push) Successful in 17m43s
CI / Build & test (Windows) (push) Failing after 32m37s
Pre-existing local resolution fix so the dependency set resolves here;
Cargo.lock follows (getrandom 0.4.3 -> 0.3.4 in the ocio tree).

Mike-Solar fdb5caabd5 color: non-sRGB preview, per-monitor display ICC, pipeline hardening
Preview now follows the project output colorspace end to end: the
display chain derives its content space from the project's OutputColorSpec
instead of a hardcoded sRGB name, self-managed ICC transforms go through
an XYZ D65 interchange stage (OCIO cie_xyz_d65_interchange) for non-sRGB
targets, and the platform layer declares the content colorspace (gpui
submodule bump). macOS defaults to OS-managed (fixes wide-gamut UI
oversaturation); Windows ACM warns once on non-sRGB targets.

Multi-monitor: the display ICC is looked up per the window's current
screen (macOS display id, Windows per-monitor DC, X11 RandR output
profile) with a throttled poll that invalidates frame caches on moves.

Pipeline precision: 10-bit+ sources fall back to YUV444P16LE + a Rust
matrix conversion when swscale lacks F32 output (no more 8-bit
truncation); BT.709/2020 SDR decodes with BT.1886 gamma 2.4 instead of
the sRGB EOTF; working-space compositing no longer clamps RGB to [0,1]
(alpha still clamped); the output node clamps to the target gamut;
frames without colorimetry metadata convert with BT.709 defaults
(warned once) instead of passing through; scopes read the
output-colorspace signal on both F32 paths.

Also: only emit rerun-if-changed for .env when it exists (a missing file
made every build fully dirty).

Mike-Solar 246de6352f app: true 10-bit presentation -- F32 frames reach the swapchain unquantized
CI / Build & test (Linux) (push) Failing after 17m38s
CI / Build & test (Windows) (push) Failing after 17m40s
The display path no longer passes through BGRA8: render workers are
asked for F32, rows are repacked, colour management runs on the F32
data, and the frame uploads to an Rgba16Float wgpu texture that the
viewer presents directly on the Rgb10a2Unorm swapchain. The BGRA8
image remains only for scopes, the eyedropper, thumbnails and the
no-GPU fallback.

Mike-Solar 244d5e860f workspace: kebab-case crates, app under crates/oak-app, shared versions
CI / Build & test (Windows) (push) Failing after 7s
All crates take the oak-* kebab-case naming (oak-audio, oak-codec,
oak-common, oak-core, oak-ffmpeg-link, oak-node, oak-otio, oak-plugin,
oak-render, oak-storage, oak-task, oak-timeline, oak-undo), with the
lib identifiers rewritten (oakrender:: -> oak_render::, oakcore_rs:: ->
oak_core::, ...) across all 226 referencing files.

The GUI application moves from the workspace root into
crates/oak-app/: src/, build.rs (paths fixed for the new location) and
tests/ travel with it, the root Cargo.toml becomes workspace-only
([workspace] + workspace.package + profiles), and the app package
inherits the workspace version. The screenshots example becomes a
standalone crate examples/simple_player/ with its own Cargo.toml.

Every crate now inherits the single workspace version
(version.workspace = true), and the workflows' crate paths and the
build docs follow the renames.

Validated with a clean cargo check --workspace.

Mike-Solar bea50f4d80 oakaudio: drop asio-sys from the lock (feature removal follow-up) 2026-08-21 10:37:22 +08:00
Mike-Solar 12ffce77db feat(common): persist configuration as TOML, migrate legacy config.ini
- save() writes <config>/config.toml (atomic temp+rename), flat keys
  at the top level and group/sub keys as [group] tables, values as
  native TOML int/float/bool/string (non-finite doubles degrade to
  strings and restore via the declared type)
- load() prefers config.toml; a legacy config.ini (C++ or pre-TOML
  Rust builds) is read once and immediately re-persisted as TOML; the
  INI file is left in place; a corrupt TOML is reported, never
  silently discarded
- cd.yml: drop a stale oakengine comment (the crate is retired)

Mike-Solar adf2cef32c feat(oakrender): render-process isolation S3 - audio over shm, per-ticket slot formats, tuning
- Audio tickets join the process backend: render_audio_batch wire
  message, workers mix straight into shm slots (SLOT_FORMAT_AUDIO_F32),
  ShmAudio payload with release semantics, crash isolation covers audio
  renders; playback audio uses an async 4-chunk prefetch drained on the
  UI tick (also fixes the sub-60fps chunk truncation bug); oversized
  ranges and dispatcher outages fall back to in-process inline.
- Per-ticket slot formats: force_format is honored (exports request
  F32 slots, dropping the BGRA8 round-trip and its 8-bit quantization);
  segments grow on demand via worker-idle rebuild with generation
  handoff; the scheduler filters over-capacity tickets.
- Adaptive defaults: 128-256MB/worker segment budgets drive slots per
  worker, batch size follows workers/slots; bench_process example
  measures throughput and adjacent-frame completion deltas
  (e.g. 4 workers: 841 fps, 4.6ms mean delta).

Mike-Solar ec7b7e6d13 feat(app): OpenFX UI wiring - effect library, inspector params, startup glue
- src/oakui/ofx.rs: startup sequence (host scan, register_plugin_nodes,
  progress reporter factory -> app progress dialog channel, active
  viewer time provider, project extent sync); all failures degrade to
  logs. oak-worker runtime also scans and registers plugins.
- Effect library groups OpenFX entries by sub-category (Filter/
  Generator/Transition/General); effect insertion goes through
  Factory::create_any so dynamic plugin nodes resolve.
- Inspector renders OFX parameters from node inputs (sliders, combo
  boxes from repeated combo_option/combo_value properties, vec/color
  spinboxes, text with explicit commit, push buttons), edits are
  undoable; persistent plugin messages surface as a card badge.
- oakplugin: push_button_clicked and per-instance persistent message
  counting (thin public layers).

Mike-Solar d61acb9e0a chore(crates): retire oakengine facade, drop oakcommon handle module
- crates/oakengine moved to crates/oakengine.bk (excluded from the
  workspace): the frozen C-ABI cdylib had no in-workspace consumers
  left after the direct-rlib migration (M14); git history is the
  authoritative backup.
- oakcommon: remove the CHandle module (no remaining users); config
  store and shared value types are unaffected.

Mike-Solar 431b9ed2b1 feat(oakrender): render-process isolation S1 - dispatcher, scheduler, real worker
Per the M15 design (docs/zh/plans/riir/M15-render-process-isolation.md):

- ipc.rs moved into oakrender with protocol v2: hello_caps,
  render_batch, batch_accepted, frame_failed; main-process-assigned
  slots; BGRA8 slot format. POSIX shm verified to 1GiB on macOS.
- ProcessDispatcher: spawns oak-worker processes, handshake, stdio
  NDJSON control, shm segment lifecycle with generation-tagged keys,
  crash detection with bounded restart and frame redispatch, zero-copy
  ShmFrameRef delivery and copy counters.
- PreviewScheduler: interleaved batch claiming (frame % W per worker,
  no work stealing), seek > playback-distance > background priority,
  credit-based flow control, crash recovery.
- oak-worker renders for real: graph snapshot deserialization, montage
  decode+composite straight into the assigned shm slot, F32->BGRA8
  final conversion in-worker, OFX plugin executor installed in-worker,
  crash hooks for isolation testing.

Thread pool coexists for now (S2 removes it). Integration tests cover
two-worker zero-copy rendering, crash isolation with redelivery, and
real H.264 footage decode into slots.

Mike-Solar c5f1d0d76c refactor(engine): pure cdylib + undo-stack test race fix (M14 R4)
- oakengine is now cdylib-only (no rlib/staticlib consumers anywhere;
  cargo tree verified) — the plugin/external C ABI layer; README and
  docs updated
- cd.yml drops the dylib embedding/re-sign steps (the app no longer
  links it)
- test race root-caused and fixed for good: the global undo stack lock
  is now a re-entrant mutex (parking_lot) shared by every test that
  drives the stack, including the previously unlocked node/render
  families; the render-manager serial-ordering bug (an earlier repro
  test initialized the global manager before the not-initialized test)
  is fixed with a shared SERIAL guard and a manager shutdown
- 5 consecutive parallel runs clean; serial 209/209

Mike-Solar 022c0a7a5a refactor(app): cut liboakengine, link module rlibs directly (M14 R3)
- real.rs rewritten over module Rust APIs (Arc<Mutex<Project>> +
  NodeId; the addref handle dance and renderer boxes are gone);
  AppEngine trait and all panels untouched
- new app assembly layers: graphops (project/timeline/edit
  primitives), effectchain (chain composition with undo groups),
  renderops (montage build + ticket render + ExportTask export),
  library via oakstorage directly
- module-side safe API additions: oakundo global value-semantic
  push/undo/redo + from_closures, oakstorage project_arc_of
- deleted: src/oakui/ffi.rs, src/oakui/host_syms.rs, the dylib link
  config in build.rs (only the gpui IOSurface framework link remains)
- the binary carries zero liboakengine references (otool/nm verified);
  101 app tests green incl. the real-render and full-res e2e tests
- behavior improvements for free: sequences land in the project graph
  (the facade scratch-project deviation is gone), footage drops take
  one undo record, effect remove/reorder undo restores edges
2026-08-16 23:36:43 +08:00
Mike-Solar a45a7af2ac refactor(cli,worker): cut liboakengine, link module rlibs directly (M14 R2)
- oak-cli: new engine.rs assembly layer maps every facade call to
  module Rust APIs (oaknode graph/serializer, oaktimeline commands,
  oakrender ticket arena, oaktask ExportTask, oakcommon config); the
  ffi/optional/host layers and build.rs link config are gone
- oak-worker: the worker session + POSIX shm transport moved into the
  crate (oakrender backend + serde_json control plane); no dylib
- both binaries carry zero liboakengine references (otool verified);
  tests green (30 cli / 41 worker)
2026-08-16 21:16:27 +08:00
Mike-Solar 8a2e45225f refactor: sink facade glue into modules (M14 R1)
- oakundo::global: the process-global undo stack, grouping and a
  command observer API; facade undo.rs becomes a thin forwarder
- oakstorage::writethrough: the binding table, snapshot thread, flush
  and config resolution; it subscribes to oakundo's observer itself
- the remaining non-forwarding facade logic (TaskMeta, effect chains,
  timeline composites, RendererBox, exporter path) is documented as
  facade-owned with reasons
- facade exports unchanged; full suite stays green (the one
  render_manager_not_initialized failure is pre-existing on the base
  commit)

Mike-Solar 025dc88c25 feat(storage,app): PostgreSQL backend (D3) + project manager window (D4)
D3: oakdb+pg:// fully wired (shared sea-orm entities, BIGSERIAL DDL,
connect-probe instead of pool retry on dead servers); Storage/Backend=pg
+ Storage/PgUrl config; 13 OAK_TEST_PG_URL-gated PG tests (verified
against a Docker postgres:16), always-on clean-error tests otherwise.

D4: DaVinci-style project manager — list with derived stats, create/
rename/duplicate/delete (confirm)/import/export (native dialogs,
ove/otio/fcpxml), shown at startup and from the file menu; facade
oakengine_library_* exports (list/create/delete/rename/duplicate/
import/export + project_load_library that binds write-through);
save/save-as menu becomes 'export project file', open splits into
from-library/from-file; status bar shows library write state; storage
activates on app start and flushes on exit; spawn_modal reentrancy
fixed (window-callback path) with a doc note.

Also: the P1 audio test's environment probe was lost in the ffi purge;
restored on cpal (the output device is cpal now).
2026-08-16 10:39:31 +08:00
Mike-Solar 5fabad8efd feat(engine): write-through persistence (M13 D2)
- facade storage session manager: project handles bind to the default
  SQLite library on project_new/load; every undo push/group_end/jump
  write-throughs via DatabaseBackend::save (diff journal); project_free
  flushes and unbinds
- background snapshot thread (Storage/SnapshotIntervalSec, latest-wins,
  newest 3 kept) with exit flush (oakengine_storage_flush)
- config-gated: storage only activates with an explicit
  Storage/Backend=sqlite, so headless consumers and tests never touch
  the real library; new exports: storage_flush/is_bound/last_error
- it_storage: kill -9 recovery, cross-session undo, snapshot pruning,
  multi-project isolation, graceful degradation
- also fixes a real config test polluting the user config.ini and the
  undo-stack test races
2026-08-16 08:52:23 +08:00
Mike-Solar 3dfeed67f5 feat(storage): database backend D1 — SQLite, node-granular journal, snapshots, persistent undo
- sea-orm schema: projects/settings/snapshots/journal (journal rows
  are per-node before/after images produced by diffing the serializer
  output, never full-project copies)
- replay = latest snapshot + journal; load_at() rewinds to any command
  seq (cross-session undo history); snapshot interval and journal
  retention configurable; snapshots pruned to the newest 3
- project manager API: list/delete/duplicate/rename, export/import
  (.ove/.otio/.fcpxml), stats derivation; PG surfaces as E_NO_BACKEND
  until D3
- docs(riir): M13 finalized (aggregate-granular persistence)
2026-08-16 01:38:27 +08:00
Mike-Solar ab1a2e9c7b refactor: drop internal bridge/ffi layers; exporter family lands
Single-lib cleanup: the per-crate src/bridge/ and src/ffi.rs layers are
gone (oakundo/oakcommon/oaknode/oaktimeline/oakcodec/oakaudio/
oakrender/oaktask/oakplugin/oakstorage); cross-crate calls are plain
Rust, CHandle marshalling shrinks to the oakengine boundary, and tests
call the Rust APIs directly (pure C-ABI wrapper tests removed where
the domain layer already covers the behavior).

exporter.h family implemented: oakengine_export_render (CLI contract),
oakengine_export_render_with_params (was a stub), last_error and
progress callback; synchronous path reuses task_create_export +
start_sync. Fixes on the way: oaktask video ticket self-deadlock,
audio params dropped on the export path, codec encoder AAC slicing and
H.264 time base. Real-mp4 tests cover both entry points, progress and
the illegal-argument matrix.

Also: oakstorage session maps null project handles to None (version-
info path), configstore test double literal 3.14 -> 3.15 (clippy PI
lint), oakaudio output callback scratch buffer + env-aware P1 test,
cli media round-trip test uses a generated 16-frame clip (no more
minute-long debug runs).
2026-08-16 00:33:45 +08:00
Mike-Solar 2248be8567 feat(storage): real oakstorage file backends + full-timeline .ove serializer
oakstorage (new workspace member): URI dispatch, pluggable backends
(ove-xml built in, otio/fcpxml via oakotio, C-vtable foreign
registration), the M10 C API surface, version info codes, last-error
and alive accounting; round-trip tests per backend.

oaknode serializer: persists the full timeline — sequence track lists,
track block lists, block ranges/media_in/speed/flags, clip footage
references, footage filename+streams, folder children — through
<custom> behavior hooks with two-phase reference resolution; loads the
C++ <olive><project><layout> containers (golden: tests/
project_with_footage.ove); round-trip is field-by-field and
byte-idempotent.
2026-08-14 15:14:38 +08:00
Mike-Solar 4240df1d71 refactor(crates): implement std::error::Error for all module error enums
thiserror derive across oakundo/oakcommon/oaknode/oaktimeline/oaktask/
oakotio/oakcodec/oakaudio/oakrender/oakplugin/oakengine/oakstorage;
Display carries the module prefix and the Failed context, source()
stays default except oakotio's #[from] forwarding. code() mappings and
variants unchanged; each error.rs gains Display/object-safety/code
regression tests.
2026-08-14 05:45:05 +08:00
Mike-Solar 5afa95c80e feat(render,app): footage decode lands (M12 P0) + UI density pass
engine:
- oakrender eval footage hook decodes via oakcodec (JobSpec::Footage
  carries filename/stream); ticket/ffi/manager wiring, real-media
  decode test with programmatically generated MPEG-2
- oakrender bridge/codec.rs + node.rs: direct oakcodec/oaknode calls;
  the crate's dlsym module is gone (project_deep_copy/sync_copy remain
  documented always-fail stubs — never implemented in oaknode)
- oakaudio waveform/decoder path adjustments for the decode hook

app (gpui + gpui_widgets):
- menu bar scrubbing: hovering another top-level title while a menu is
  open switches to it; popup width is content-aware (CJK-aware) instead
  of fixed 160px
- density pass: window rem 16 -> 14px, menu rows 26 -> 22px, dock tabs
  32 -> 26px, viewer transport tightened
- open/import/save-as use the native platform file dialogs
  (prompt_for_paths / prompt_for_new_path; multi-select import);
  MockEngine records imported footage for tests
- project explorer Tree/Icons toggle is localized (explorer.tree /
  explorer.icons widget keys)

Mike-Solar 05e42668cb build(ffmpeg): static GPL FFmpeg 8.0 via project script + FFMPEG_DIR
- tooling/ffmpeg/build-ffmpeg.sh builds release/8.0 static+PIC into
  .cache/ffmpeg: GPL/version3, every free-license external codec lib
  probed via pkg-config (enabled when present), per-OS hardware
  acceleration (VideoToolbox/AudioToolbox, VAAPI/VDPAU/libdrm,
  D3D11VA/DXVA2/MediaFoundation, nvenc when ffnvcodec exists)
- tooling/install-deps.sh installs those libraries on Homebrew / MSYS2
  UCRT64 / Debian-Ubuntu / Fedora / Arch; nothing in the build sudo's
- ffmpeg-next's own build feature is unusable (every crate-version to
  FFmpeg-release pairing is broken upstream: 9.0.0->FF9 AVCodec fields,
  8.1.0->FF8.1 new enum variants, 8.0.0->FF8 FF_PROFILE rename), so
  ffmpeg-next 9 + FFmpeg 8.x headers via FFMPEG_DIR it is
- new links-crate oakffmpeg-link emits the static FFmpeg's transitive
  link flags from its .pc files (cargo only propagates them from links
  crates, and rustc prunes the flags unless the rlib is referenced —
  hence the force_link statics)
- docs/build.md updated for the Rust workspace flow
2026-08-11 20:04:44 +08:00
Mike-Solar 26009a5ea5 refactor(oakaudio): drop ffmpeg_bridge fb_* imports, call ffmpeg-next in-process
- processor.rs: resample/channel-convert/time-stretch now runs an
  in-process FFmpeg filter graph (abuffer -> atempo -> aformat ->
  abuffersink) via ffmpeg-next
- waveform.rs: extraction decodes through oakcodec's FFmpegDecoder
  (interleaved f32) instead of the fb_decoder/fb_audio_graph pair
- bridge/ffmpeg.rs and the null fb_* test stubs deleted;
  oakcommon::ffmpegutils bridge constants become plain ints
- liboakengine.dylib no longer imports any fb_* symbol (nm -u clean);
  the remaining runtime imports are the host-provided oakcore_* symbols
- real decode/resample tests added (generated PCM input, no network)
2026-08-11 16:10:14 +08:00
Mike-Solar 063837446d feat(app): link liboakengine.dylib via frozen C ABI; UI fixes
- App no longer depends on the oakengine rlib: build.rs links the
  built liboakengine.dylib (+rpath, -export_dynamic, IOSurface) and
  src/oakui/ffi.rs declares the pure-C surface; RealEngine calls only
  the frozen oakengine_* C ABI
- host_syms.rs provides the oakcore_*/fb_* host symbols the dylib
  imports via dynamic lookup
- Fix Preferences dialog crash (spawn_modal reentrancy) with a
  regression test
- Timeline toolbar and viewer transport render C++-era icons (16px
  grid, dark/light themes) with localized tooltips
- i18n: complete en-US table, add untranslated-key detection test
- New dialogs module (preferences, export, progress)

Mike-Solar 013a175707 refactor: workspace layout — crates/, app at root, legacy C++ removed
Single mechanical restructure commit:
- root Cargo.toml = oakapp bin + workspace; one cargo build produces
  oakapp, oak-cli, oak-worker, liboakengine.dylib
- app/rust/src -> src/ (app at repo root, no rust/ nesting)
- src/<mod>/rust -> crates/oak<mod>; src/oakcore-rs -> crates/oakcore;
  src/bindings/oakotio -> crates/oakotio; src/engine/rust ->
  crates/oakengine (keeps cdylib+staticlib+rlib)
- public C headers include/<mod>/ -> crates/oakengine/include/<mod>/
- OFX SDK headers vendored into crates/oakplugin/ofx/ (HostSupport gone)
- legacy deleted: old src/ C++ modules, engine/, core/, ffmpeg_bridge/,
  app/ (Qt), cli/worker C++, root CMakeLists, third_party/KDDockWidgets
  submodule, otio-install, all build-* output (~40GB)
- oakstorage kept but excluded from the workspace (skeleton w/ todos);
  gpui excluded (own workspace)
- verified: cargo build green, cargo test --workspace 1845/0
  (with the documented OCIO_RS_* env override for the homebrew OCIO)
