# Installed native readiness action contract
[README.md](README.md) describes prerequisite ordering. This action is a hosted
Ubuntu preparation step, called after checkout, pinned source fixtures and
- Python/uv setup. It has no inputs or acceptance outputs. Java and EPUBCheck
+ Python/uv setup. Its `prepare-lean` input accepts only `true` or `false` and
+ defaults to `true` for complete native roles. The Code diagnostic explicitly uses
+ `false`; it does not exercise Lean. This action has no acceptance outputs. Java and EPUBCheck
nominations are exported as `TEMPLATE_NATIVE_JAVA` and
`TEMPLATE_NATIVE_EPUBCHECK` for the caller's explicit tool arguments.
Preserve Root `uv.lock`, Source package/tool pins, upstream licenses and existing
local setup actions. Do not combine independent project locks or use a cache,
path or tool label as provider authority. Cache warming precedes the cold

+ operation. Complete native roles retain the original 14400-second deadline;
+ the incomplete Code diagnostic retains its 900-second deadline. All later
+ provider/Code/native predicates belong to the genuine installed launcher and
+ reader. Preparation establishes no claim that either operation fits its clock.
Retain genuine preparation failures. Keep temporary cache-warming cleanup
restricted to the action's own `mktemp` destinations. This action does not clean
shared source, runtime aliases or acceptance evidence. The same preparation must
serve originals, readers and handoff under the
[required workflow](../../workflows/platform-required-acceptance.yml) and
[release workflow](../../workflows/release.yml).
Maintain the [parent action contract](../AGENTS.md), the local doc pair and
resolving links. Run actionlint after action edits; complete docs and release
acceptance remain caller-owned gates.
