Version 0.123 adds pinned IMX500 inference controls: exact sensor selection, cached absolute/aspect ROI, device IDs, explicit saved restoration and owned failure observations in C/Zig/Bun. Firmware/network loading, input tensors, model postprocessing and physical acceptance remain open.
Version 0.122 adds request-local inference geometry and KPI: staged ROI/scaler projection, centered aspect crops, owned main/lores plans and exact inference counters with the Picamera2 conversion. Firmware/network loading, hardware ROI updates, input tensors, model postprocessing and physical acceptance remain open alongside the other parity families.
Version 0.121 adds owned CNN output tensors: selective request snapshots, checked column/row storage and retained capture context in C/Zig/Bun. Firmware/network loading, ROI/input tensors, model postprocessing and physical IMX500 acceptance remain open.
Version 0.120 adds timestamp-matched multi-camera capture: bounded same-host request groups, backend readiness, retained results and joined cancellation/stop/cleanup. Physical synchronization and the other parity families remain open.
Version 0.119 adds owned raster compositing: Home exact source-over shared with APNG, clipped RGBA8/16 results, explicit sample/color policy and two-input copied async jobs with joined cancellation. Remaining image operations, color conversion, GUI/GPU and physical acceptance remain open.
Version 0.118 adds multi-object capture planes: linear planar/semi-planar imports and factories, per-object budgets/maps/fences, exact new factory loans, unchanged logical geometry and retained cleanup. GPU-specific layouts and physical Pi acceptance remain open.
Version 0.117 adds automatic capture buffer factories: actual negotiated layouts, asynchronous caller-input release, bounded native notification ownership, joined cancellation/rollback and async Camera.open in Bun. Physical Pi acceptance and the remaining parity families stay open.
Version 0.116 adds explicitly provisioned caller-owned Linux capture buffers, exact negotiated allocation snapshots, whole-object budgets, FD identity/offset validation, DMA_SYNC capability checks, inherited mode workers and retryable cleanup in Zig/C/Bun; see capture-imports.md. Automatic factory callbacks, multi-object/GPU frame layouts and physical Pi acceptance remain open.
Version 0.115.1 fixes retained cleanup of failed shared-memory unmaps in Home and camera export/remote owners, with bounded explicit retry and telemetry in Zig/C/Bun. See shared-cleanup.md. This is an ownership prerequisite for custom allocation; imported custom buffers and allocator factories remain open.
Version 0.115 adds bounded persistent DMA heap/synthetic capture allocation in Zig/C/Bun with actual-layout reuse, retained request/map/export owners, worker pins, mode/recorder/group rollback and independent overlapping reconnect loans; see capture-allocator.md. Shared Home resources retain cleanup failures for retry. Custom allocator callbacks, GPU storage, physical Pi acceptance and the other capability families below remain open.
Version 0.114 adds bounded owned JPEG loading through shared Home scan and restart reconstruction, component sampling, progressive refinement and source metadata, with native workers and shared JPEG/PNG file budgets. See jpeg-loading.md. Arithmetic/lossless/higher-precision JPEG, further formats/operations, profile conversion and physical acceptance remain open alongside the other families.
Version 0.113 adds separate DRM alpha planes through shared Home two-plane atomic ownership, named blend modes, strict stacking, async overlay jobs and joined mode/recorder restoration. See drm-overlays.md. Physical acceptance, desktop/GUI integration, mode setting and the remaining capability families below are still open.
Version 0.112 adds optional explicit RGB16/BGR16 high-byte DRM display copies through Home's checked word views and two reusable driver allocations, with CPU coherency fences, input retirement before flip waits, storage telemetry and retained cleanup retries; see drm-rgb16.md. Other formats/modifiers, desktop/GUI integration and physical acceptance remain open.
Version 0.111 attaches the native DRM worker to Camera through an explicit backend, bounded skip feed, async view/source/drain/stop jobs and joined mode, recorder/group, close and reconnect transitions; see camera-drm-worker.md. Desktop integration, additional display formats and physical acceptance remain open. This does not complete the overall parity goal.
Version 0.110 adds an independent native async DRM consumer with bounded worker jobs and Bun frame/view/background/drain/close operations; see drm-async.md. Version 0.111 provides explicit Camera ownership as described above; the independent consumer still requires application-managed source retirement.
Version 0.109 adds direct linear DMABUF DRM preview through shared Home atomic plane ownership and C/Bun APIs; see drm-preview.md. Flip completion proves source retirement; uncertain submissions retain possible owners for explicit cleanup retry. Desktop leases/shared-card ownership and physical display acceptance remain open alongside the full capability families below.
Version 0.107 adds bounded sequential APNG display canvases through shared Home integer compositing and C/Bun ownership; see png-compositing.md. Additional image formats/operations, asynchronous compositing and other animation/color semantics remain open alongside all other required capability families and hardware acceptance. This feature does not complete the overall parity goal.
The goal is full capability parity through Zig/C and TypeScript/Bun, with Home codecs/containers and no Python or FFmpeg runtime, tools or bindings. Publishing a feature release or passing existing tests does not complete this goal.
The reference audit pins raspberrypi/picamera2 commit 5e2a35d3bb230825c98c56d98e01b41ddeb43e86. The adjacent parity-reference.json records public names in 51 source modules, including capture, configuration, preview, encoders, outputs, allocators, remote processing and camera-specific inference. It was derived by inspecting source text, never executing it. It is a lexical inventory, not a complete semantic export inventory: conditional definitions, inherited methods, configuration fields, constants and documentation still need manual review before completion. Recheck upstream changes during the final audit.

| Scheduling/extensibility | Bounded Bun jobs, cancellation, completion callbacks, drains, joined native ownership, exact frame dropping/timestamp waits, scoped pre/post callbacks with main-thread mode-worker handoff and explicit retained acquisition | Complete arbitrary dispatch/wait/cancel/flush semantics and remaining callback/allocator integration behavior |

Python class signatures and FFmpeg/PyAV subprocesses are not implementation requirements under the user's constraints; their camera/media/output capabilities remain requirements and must have verified Zig/Bun/Home equivalents. Platform integration gaps cannot be declared complete merely because SDL or a custom sink exists. Optional hardware must have an implementation and appropriate acceptance evidence, not fabricated sensor results.
For each reference capability, identify its concrete implementation, public API, positive and failure tests, platform coverage and required hardware observations. Review omitted exports and upstream changes. Distinguish synthetic semantics from physical results. All required capabilities and validation remain in scope until proven; this worklist must not be reduced to the already implemented subset.
Still-metadata foundation evidence is tracked in still-metadata.md. The shared Home ICC profile/curve corrections and independent CMM tests are available; public ICC embedding and scoped capture Exif options are implemented. Complete tag/thumbnail semantics and physical metadata acceptance remain required. A valid profile alone does not establish matching pixels or sensor quality. Temporary-mode files now use staged publication with request-callback/restoration preconditions and joined native disposal; see staged-files.md for the implemented claim, cancellation and I/O outcome contract.
The shared Home layer additionally implements combined JPEG/PNG/TIFF ICC/Exif embedding with pointer/byte-order relocation and independent reader/decoder checks. Capture-facing Exif now derives selected dimensions, exposure, gain-based ISO and explicit UTC times, with caller precedence and copied admission across file, owned-byte, focus and temporary-mode jobs; see capture-exif.md. This is a scoped software capability, not complete Exif/Picamera2 or physical sensor acceptance.
RGB16 processed formats now have checked main/lores word capture, owned RGB16 copies, full-precision PNG/TIFF/PPM and explicit high-byte preview/JPEG/video input; see rgb16.md. Physical format/bit-depth support, higher-bit-depth video, general transfer/gamut conversion and the broader required families above remain open. This feature does not complete Picamera2 capability or hardware parity.
The 0.81 APNG foundation exposes the checked Home encoder through Zig over owned or borrowed capture raster views, with frame rectangles, rational delays, disposal/blend and separate default-image support; see apng.md. Home's Image API also receives corrected animated PNG encoding. Version 0.82 adds bounded Bun/C encoding jobs, owned main/lores RGB8/RGB16 bursts and joined staged publication; see apng.md. Image-object/compositing equivalents, animation metadata, temporary-mode animation conveniences and the broader still-media requirements remain open. This does not complete the still-media family or hardware parity.
Version 0.83 adds Home GIF still capture across C/Zig/Bun/CLI and processed main/lores streams, with explicit palette/RGB16/alpha policies; see gif.md. Ordinary and focus-locked files now delay publication through callbacks and CAF restoration. Image animation/compositing, decoded objects, background GIF compression jobs, further metadata/format work and physical acceptance remain open. This does not complete the still-media family or the overall goal.
Version 0.84 adds owned image capture/callback equivalents, checked word conversion and staged standalone saves after source/camera retirement; see image-objects.md. General resampling, decoded file formats, palette/float/gamut conversion, temporary-mode image conveniences and complete image/animation semantics remain required work as applicable. Hardware acceptance and the broader parity families remain open; this does not complete the goal.
Version 0.85 adds explicit owned image resizing and capture-time dimensions, using Home's native-precision, widened-window separable resampler; see image-resizing.md. Filters/alpha/limits are defined explicitly and do not promise Pillow-identical samples. Remaining image transforms, decoding, temporary-mode image conveniences, complete compositing/color semantics and physical acceptance remain open. This does not complete the still-media family or overall goal.
Version 0.86 adds temporary-mode owned image jobs with target-time native precision/provenance, joined release/restoration, worker resampling, one buffer transfer and post-preview sealed publication; see mode-images.md. General decoding/compositing, animation conveniences and the other required capability families remain open. This does not complete the overall parity goal.
Version 0.87 adds retained fd export owners and independent exec/SCM_RIGHTS validation; see frame-exports.md. Production process supervision, ACK routing, timeout/exit cleanup, remote scoped requests/pools and persistent allocator semantics remain required. Descriptor export alone does not complete memory/ process parity, physical DMA acceptance or the broader goal.
Version 0.88 adds bounded local descriptor transport and receiver-owned remote frames with explicit ACKs and Home image copies; see frame-channels.md. Production process jobs/pools, automatic result/ACK routing, timeout/cancellation/exit joining, configuration/property snapshots and remaining remote conveniences remain required. This does not complete memory/process or physical DMA parity.
Version 0.89 adds supervised actual process jobs/pools with native ownership, argument/result reservations, joined cancellation/failure, generation restarts and callback-aware drain/close; see process-pools.md. Complete remote array/ buffer/save/DNG and configuration equivalents, richer values, automatic recovery, persistent allocator/GPU integration and broader hardware/parity families remain required. This does not complete the overall goal.
Version 0.90 adds compact remote stream bundles, shaped typed arrays, physical buffer and Home raw16 copies, immutable request calibration transport and calibrated DNG/processed saves across C/Zig/Bun/process workers; see remote-media.md. Further remote configuration/property, async/metadata/file-like save semantics, advanced DNG, automatic recovery, persistent allocator/GPU integration and all other required families and physical acceptance remain open. This does not complete the overall parity goal.
Version 0.91 adds remote request-derived Exif and ICC image encoding/saves, including JPEG defaults, selected dimensions/exposure/gain ISO/model/UTC, explicit overrides and unchanged channel schema; see remote-exif.md. Complete metadata, async/file-like publication, remote configuration/property, allocator, automatic recovery, optional integrations and physical acceptance remain open. This does not complete the overall parity goal.
Version 0.92 adds immutable request configuration across C/Zig/Bun, exports and remote process workers, using bounded Home catalog projection without another transport version or fd; see request-configuration.md. Full property snapshots, async/file-like publication, allocator and automatic recovery, optional integrations and physical acceptance remain open. This does not complete parity.
Version 0.93 adds bounded native remote image encode/save jobs and asynchronous DNG with source-independent input, Home workspace budgets, copied Exif/ICC and joined staged publication/cancellation; see remote-async.md. Full property snapshots, file-like and parent-controlled process publication/cleanup, allocator and recovery semantics, optional integrations and physical acceptance remain open.
Version 0.94 adds parent-controlled process file publication through the existing result/ACK transport and bounded copied-byte native staging; see process-files.md. Direct descriptor streaming, file-like destinations, full property snapshots, allocator/recovery and optional camera integration families and physical acceptance remain open. This does not complete the overall goal.
Version 0.95 adds joined sequential still destinations on local frames, remote frames and owned image objects, native async local/raster encoding, bounded partial writes and flush/cancellation, and retained Home admission through slow output I/O; see image-outputs.md. Existing staged image bursts preserve their 32-file bound with cancellable codec-capacity waits. Capture/mode sink convenience jobs, incremental streaming, full metadata/property/allocator/recovery behavior, optional integrations and physical acceptance remain open. This is not parity.
Version 0.96 adds ordinary, CAF-locked and temporary-mode camera output jobs, with parent-owned native image preparation, source retirement and selected callbacks/CAF/camera/preview restoration before bounded sink delivery; see capture-outputs.md. Still hooks share asynchronous lifecycle reentrancy guards. Burst/series sink conveniences, further properties/allocator/recovery behavior, incremental encoding, complete metadata/device integrations and all physical acceptance remain open. This does not complete full Picamera2 parity.
Version 0.97 adds exact owned source properties across local frames, callback scopes, retained exports and actual remote/process workers. Home's new checked nested-catalog helper preserves vendor/native/opaque bytes within existing metadata transport; camera caches immutable session properties and preserves legacy absence and bounded combined-catalog failure. See request-properties.md. Mapping conveniences, remaining allocator/GPU/recovery/output/device behaviors, complete metadata semantics and all physical acceptance remain open.
Version 0.98 preserves full source Model strings in automatic Exif and calibrated DNG across local/remote copied jobs, with Home strict borrowed string lookup, explicit Exif override precedence, bounded dynamic TIFF directories and charged async model ownership. See source-model.md. Localized model/DNG metadata, complete image transforms/decoding, remaining allocator/GPU/recovery/output/device families and all matched physical/performance acceptance remain open. This is not full Picamera2 parity.
Version 0.99 adds exact native-precision owned-image rotations/flips/transpose through Home's checked copies and shared native geometry, with C/Zig/Bun entry points and retained color/request provenance. Home Image operations now preserve native words, indexed palettes and transformed animation rectangles/owners. See image-transforms.md. General-angle/affine transforms, compositing, decoding, remaining allocator/GPU/recovery/output/device families and physical/performance acceptance remain open. This is not full Picamera2 parity.
Version 0.100 adds bounded PNG/APNG decoding and Bun file loading, exact native word reconstruction, packed/Adam7 input, explicit raw animation rectangles and copied color/Exif metadata. Shared Home work also corrects the public Image decoder; native decode jobs reuse Home gates/budgets and share still-encoder admission. Other decoded formats, compositing and the remaining families above remain open. No hardware or comparative-performance acceptance is implied.
Version 0.103 adds reusable bounded raw TCP/UDP video output and a TCP byte sink for Home Matroska A/V, with checked shared Home send progress, peer half-close, joined lifecycle/deadlines, shared PTS, isolated recovery and async output splits. See socket-output.md. Listening/process outputs, broader network protocols and sessions, remaining buffering/flush behaviors and all other capability families and physical acceptance remain open. This does not complete full parity.
Version 0.104 adds supervised process video output and Home-container byte sinks, with shared Home bounded diagnostics/control framing and a standalone Zig host, exec readiness, joined cancellation, ordinary descendant groups and parent-fd loss, immutable argv/env, shared socket/process admission, isolated recovery and async splits. See process-output.md. Additional media containers/protocols, escaped or hard-killed-supervisor process-tree policy, remaining output semantics and every other required family and physical acceptance remain open. This does not complete Picamera2 parity.
Version 0.105 adds forward-only AVC/HEVC/AAC fragmented MP4 byte outputs with bounded deferred initialization, real first-PCM clock binding, final tail trim, 64 KiB prefix writes, async splits/restart, circular snapshots and isolation. See forward-mp4.md. This general ISO BMFF mode does not claim CMAF/MSE or player interoperability. Broader containers/protocols, remaining output and device families, physical synchronization and matched performance remain open. The full Picamera2 parity goal is still active.
Version 0.106 adds one-peer listening TCP byte/raw outputs, shared dialing/accept TCP chunk ownership, immutable session endpoints, joined bind/accept cancellation, write deadlines and global transport admission. Real loopback tests exercise raw Home codecs, PCM Matroska, decoded AAC fMP4, async splits and isolated recovery. See listening-output.md. Borrowed socket adoption, multiple consumers, broader protocols, other capability families and physical/performance acceptance remain open. This does not complete Picamera2 parity.
Version 0.106.1 hardens process retirement with independent cancellation and proof channels, joined ownership of both sockets, native closed-descriptor checks and controlled unread-cancel terminal fixtures. The record ABI and strict final proof requirement remain unchanged. Full Picamera2 parity and physical acceptance remain open; this is an output-lifecycle correction.
