# Reference implementations

Inspection dates: **2026-07-24** (initial implementation) and
**2026-07-26** (remaining-slice integration).

The references were cloned beside av-tools under
`/mnt/DATA/git/references/`; no reference repository was nested in this
working tree. Revisions are full immutable commit ids.

| av-tools, `git@git.add-ideas.de:lotobo/av-tools.git`                 | no revision: canonical `main` was unborn and had no commits                                                            | canonical destination and licence/history check                                                                                         | the empty repository was scaffolded in place; no prior code existed                                                                                                                                              |
| Toolbox SDK, `https://git.add-ideas.de/lotobo/toolbox-sdk.git`       | `ef2dab4b46c61812c9a877d8a19fe497b4a4630a` (SDK 0.2.3)                                                                 | manifest schema/definition, `AppShell`, context behavior, shared styles, token-free registry, nested-path checks and toolchain baseline | published 0.2.3 packages are direct dependencies; documented usage patterns were followed; no SDK source file was copied                                                                                         |
| Toolbox Portal, `https://git.add-ideas.de/lotobo/toolbox-portal.git` | `bda9da044d61c109afd9969d357cc27f76648938` initially; `5c052bc6d1073a66600cfddc44c0e16da34bede8` for final integration | release ZIP/sidecar/lock formats, independent assembly, catalogue behavior, path security, nested deployment and production headers     | no portal application source was copied; the AV smoke harness consumes only an exact cloned Portal revision; the separate Portal worktree contains its own reviewed integration patch                            |
| ffmpeg.wasm, `https://github.com/ffmpegwasm/ffmpeg.wasm.git`         | `f876f907c7e9b9bf51d4ed0b913a855a63ae63fc`; pinned release baseline `71aa99d37c02a7b4c435275ca9ef50e612f6efa1`         | current API, worker lifecycle, filesystem, loading, ST/MT behavior, licence documentation and build layout                              | no reference-worktree source was copied; wrapper/util remain exact npm dependencies, while the five core assets are rebuilt from the recorded source/toolchain/patch profile and verified against the build lock |

For the **pinned** package set, the more specific upstream release tag
`v12.15` at `71aa99d37c02a7b4c435275ca9ef50e612f6efa1` was also inspected. It
contains `@ffmpeg/ffmpeg` 0.12.15 and the source configuration for core
0.12.10. That revision's build selects FFmpeg n5.1.4. The shipped
`0.12.10-reviewed-stack5m.1` assets additionally apply upstream ffmpeg.wasm
commit `b409e36475bc21f0451b5b1e1d126fa82871439a`; exact build and source
identities are in `SOURCE.md` and `docs/FFMPEG_BUILD.md`.

The active `/mnt/DATA/git/toolbox-portal` worktree has immutable revision
`5c052bc6d1073a66600cfddc44c0e16da34bede8` as `HEAD`. Its staged cache-rule
extension is documented separately and is not represented as a published
revision.
