Mechanically re-derived: bin/debrand runs over a fresh import of posthog/posthog@fa1a9a60d4 (2026-08-06). The pipeline (.hanzo/workflows), the Dockerfiles and bin/docker* entrypoints, compose files, LLM.md and the squashed initial migration are restored from the shipped tree, same as the previous import. The prune's import-closure guard kept 21 products the new core now imports; dropping them is a refactor now, recorded rather than forced.

"""The canvas platform contract, loaded from the builder package's manifest.
|
|
|
|
manifest.json is the single source of truth shared by the Node builder
|
|
(build.mjs), this Python validator/build service, and the artifact origin's
|
|
CSP. The desktop app asserts its own copy against the same file in a contract
|
|
test, so a drift in pinned dependencies or limits fails loudly instead of
|
|
diverging silently.
