PostProject 0.9 development qualification

This report records the qualified f456958c candidate. Additional workflow changes are being implemented under the Revised 0.9 workflow design; their qualification is separate. The earlier package/checksum set remains intact.

Prepared 0.9.0-alpha.1 (Python 0.9.0a1), C ABI 53, 344 exports, 38 public layouts, SQLite schema 27, exchange protocol 1 and CLI JSON 1. This unpublished development candidate qualifies against published v0.8.0-alpha.1 (7e097bd) on 2026-10-12. Required local, platform and maintained-integration checks pass; external limitations remain below.

Delivered behavior

Python uses one Edit type for additive, retained-view and detached decisions, with consistent context keywords and explicit commit. Ordinary metadata keys and scalar values use checked native inputs; typed values retain all lossless domain meanings. Single files stage directly from paths. Python and Rust offer bounded lazy scans owned by the caller’s read view. C/C++ resolution options are constructed atomically, and Rust/C/C++ commit returns the caller’s receipt through one operation. The CLI has one scoped decision option.

ADRs 0068–0075 record these source/API changes. Transaction terminality, conflicts, lease fencing, complete native capture, passive replay, copied-value ownership and structured errors retain their meanings. No storage or protocol change, new standards mapping or stable API family is introduced. Historical 0.8 artifacts are unchanged.

The Move an integration from 0.8 to 0.9 provides five runnable Python before/after tasks and corresponding native, Rust and CLI recipes. The API ergonomics audit records caller costs and design choices; the Python API measurements for 0.9 records installed 0.8/0.9 workloads and their measurement limits.

Completed local checks

Boundary	Evidence
Rust	All six required gates; exact Rust 1.85 workspace checks and tests
Native SDK	Nine installed contracts; 344 symbols; 38 Rust/C/ctypes layouts; both C++ error styles
Memory checks	Nine ASan/UBSan native contracts and sanitized C smoke
Python	Installed 3.11 and 3.14: all 143 tests pass with the installed CLI enabled; positive typing and twelve wrong-ID negatives
Examples/docs	84 installed extracted examples; Doxygen coverage; strict Sphinx, spelling and offline links
Consumers	Manager: eight tests; each OpenAssetIO/OTIO demonstration and sample host; native C++ NLE, OBS and Natron contracts
Real hosts	Blender 5.2.2: 24 passed, one future-version skip; OBS 32.2.2 normal/error/disabled paths; Natron 2.5.0 normal/negative/fallback
Handoffs	OBS → Blender; Kdenlive 26.08.2 → Blender → Manager, including identity, moves, conflicts and stale outputs
Exchange	Actual Blender-authored history reconstructed in two independent passive processes, including duplicate apply and reopen
Clean packages	Relocated native archive: nine contracts with Cargo prohibited; fresh installed Manager/demo wheels and bundled SDK loading

The pinned OTIO upstream linker emits its known unversioned-trait deprecation warning; that warning is retained. The actual host exchange fixture has three assets, two activities and no jobs; it is not independent worker evidence. Ardour’s installed native audio resolver passes. Its full local configure remains blocked by the missing liblo dependency; full CI results follow.

Completed CI

Pipeline	Verified result
SDK, 3d1b5f51	All 16 jobs pass, including Linux/macOS/Windows tests and installed native packages, glibc-2.28 wheel, MSRV and sanitizers
Downstream, 3d1b5f51	All 11 jobs pass, including both full Ardour builds and both OpenAssetIO dependency sets
Kdenlive, 09bd9bf	Full builds and tests with and without PostProject pass
Blender, ef5274a	Stable 5.2.2, optional 5.3 beta and lint all pass

The CI source and job record identifies the checked revisions. Downloaded Linux, macOS and Windows native packages have matching public headers, allowing Windows line endings. The Linux package’s 344 exports and installed Python quickstart pass locally. The earlier stale inventory, helper assertion and Rust 1.99 lint failures were corrected; these results supersede those failed runs.

Prepared artifacts and application targets

The review set includes headers, shared/static libraries, CLI, relocatable CMake/pkg-config metadata, typed Python wheel, Blender extension, Manager/demo wheels and source archives for all 13 repositories. Native packages and wheels include SDK licenses and an inventory of 91 Linux native dependency notices. They are workstation Linux artifacts, not qualified manylinux releases. The external artifact manifest and checksums identify exact inputs separately from their archives; source and repository provenance are recorded in the repository inventory.

Kdenlive 26.08.2 (ef543982) is the new pinned stable target. Its ten patches apply after adapting the proxy wait hooks to its member-owned process. Full with/without-SDK builds, two enabled/one disabled test suites and the complete shared-production handoff pass. Blender 5.2.2 LTS, OBS 32.2.2, Natron 2.5.0 and Ardour 9.8 retain their verified stable pins. Historical host qualification remains release-scoped.

External outcomes and limits

• Licensed Nuke: not executed. Manager/configuration/sequence tests pass against both standalone and Nuke 17 shipped OpenAssetIO dependency pins.

• Public releases: prepared and unpublished; no tags or registry uploads.

• Deployment: the practical pilot descriptions at postproject.org match site revision 59a5f25; both deployment jobs pass. Documentation source 3d1b5f51 is deployed and checked live; strict local documentation and six website previews pass.

• Integration guides: Blender, Kdenlive and Nuke have setup, validation and support notes. No upstream acceptance, endorsement or official listing is claimed.

No second independent worker executes renewal, failure or cancellation here. Automated host fixtures do not establish a human interactive or commercial-host pass. No network service, media transfer, implicit synchronization or editable replica is delivered.
