# setup-acceptance-documents contract

This composite action only orchestrates preparation of official document prerequisites.

Do not call it on a shared workstation. It uses fresh `RUNNER_TEMP` storage

and the disposable hosted runner's user font/tool directories. Third-party

archives and model blobs must retain their exact source-pinned hashes and lengths.

The model action binds an unoccupied loopback port, disables cloud operations

and implicit model acquisition, and records its owned daemon PID and birth.

Every caller of that action must perform identity-checked process-group cleanup

in an `always()` step. No shared service may be stopped or replaced.

`mode` defaults to `native`. Validate exactly `native` or `converter` before

cache restoration, download or setup. Pandoc/crossref verification is

unconditional; native package and JuliaMono preparation are conditioned only on

that validated output. Genuine acceptance callers use native preparation;

routine infrastructure smoke selects converter and separately prepares its

declared readers and TeX. Ordinary project cells explicitly select native for EDA and

converter elsewhere, according to their actual source-declared tests.

Cache only official archives, with OS, architecture, validated mode and source

identity in the key. Validate exact length and SHA-256 again before every use;

cached data cannot supply test outcomes or acceptance.

Run `actionlint` after edits and retain genuine failed preparation diagnostics.

See [README.md](README.md) for usage.

Linux callers in either mode, and all native callers, must first prepare their selected locked Python environment.

`python-executable` defaults to `.venv/bin/python`; common acceptance explicitly

selects its prepared `output/runtime-envs/3.14/bin/python`. The helper's

`--prepared-python PATH` mode preserves that environment, checks actual CPython

support, and runs the unchanged LaTeX package validator with it. It performs no

Python bootstrap, dependency sync or implicit reconciliation. Missing runtime,

native tools, packages or failed validation remain failures. Linux native

preparation explicitly includes `texlive-plain-generic` for the actual `soul.sty`

provider. After platform package preparation, require successful `kpsewhich

soul.sty` resolution and an actual provider file; retain its path and SHA-256.

A package inventory or cached archive cannot replace that runtime lookup.
