Competition Supply Chain
Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.
Use this skill when the challenge is really about provenance, dependency drift, build output, release flow, or what runtime artifact actually got shipped.

Quick Start
- Split the problem into source, dependency resolution, build, packaging, publish, and runtime consumption.
- Decide where the first divergence occurs between intended artifact and runtime artifact.
- Keep provenance as a compact chain, not a scattered set of observations.
- Reproduce the smallest possible build or package path that still shows the issue.
- Separate checked-in intent from what the pipeline actually emitted.
Workflow
1. Trace Provenance End-To-End
- Map source checkout, lockfiles, dependency fetch, pre/post-install steps, build scripts, packaging, publish target, and runtime consumer.
- Compare declared version, resolved version, and shipped artifact.
- Note registry, cache, mirror, or CI environment differences.
2. Reconcile Build-Time And Runtime
- Compare manifests with image layers, mounted secrets, generated files, and runtime hooks.
- Identify whether the decisive mutation happens in dependency install, build step, publish step, or runtime bootstrap.
3. Report The Break Point
- State the earliest point where provenance diverges.
- Keep evidence in one short chain from source to runtime consumer.

What To Preserve
- Declared dependency, resolved dependency, and runtime artifact versions
- CI step names, registry pulls, artifact hashes, and image or package layers
- The runtime consumer that actually accepts or executes the artifact
