Index immutable replay evidence and fix Unity 2021 shipping graph

[Eli Pinkerton (wallstop)]

Why

Issue #509 completed its immutable replay publication and restore gate, while an exact-master endpoint run for #506/#508 exposed one incorrect edge in the Unity 2021 shipping package-lock fixture.

What changed

• Indexes the immutable native lifecycle replay bundle with complete release, asset, source, verifier, and digest identities.
• Models the exact official com.unity.sysroot.linux-x86_64@2.0.9 -> com.unity.sysroot@2.0.10 dependency edge observed on Unity 2021.
• Strengthens the package-lock tests to reject a missing edge or changed dependency version while preserving exact names, versions, depths, registry, source, and root-package checks.

How we know

The #509 release is immutable and passed an independent anonymous clean-clone restore, inventory, SHA-256 verification, replay of all three message kinds, and clean-worktree check.

Run 34781552796 supplied the endpoint RED: all three ordinary Unity 2021 modes passed, then all 20 shipping cells rejected the same missing modeled edge before BuildPipeline. Unity's official registry metadata declares that exact dependency.

Focused shipping-fidelity tests pass after failing against the old production graph. npm run validate:all and all 1,331 script tests pass. The workflow remains manual-only for shipping/native evidence; recurring CI work and test filters are unchanged.

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update
• Refactor (code change that neither fixes a bug nor adds a feature)

Checklist

• All applicable tests pass locally
• Code is properly formatted
• Added regression coverage for the observed endpoint failure
• Updated the evidence documentation
• No CHANGELOG entry is needed because user-facing behavior is unchanged
• No breaking changes
