To assess an engineering-history export, check the relationships it preserves, not just the files it contains. A Git snapshot can show code at a version. Commits add recorded parent relationships and metadata. Pull request records can add conversations, reviews and checks. An export may contain some of these without retaining the links needed to reconstruct a particular review.

The useful decision is whether this export supports your specified question. For example, can a reviewer identify which revision a comment concerns and which version a check evaluated? A folder of source files and a spreadsheet of comments do not establish those relationships merely because both came from the same project.

Which engineering-history question must the export answer?

Choose a question narrow enough to test on one permitted case. You might ask whether the export shows what changed between two versions, whether a review comment relates to the revision eventually accepted, or whether a recorded check concerns the version being assessed. These are different evidence requests.

Write down the required relationship before examining the export. For a review-comment question, that could be a connection from the comment to the pull request and the relevant diff or revision. For a change-history question, it could be a commit's parent relationship and resulting tree. Do not treat additional records as a substitute for the one relationship your question requires.

This article proposes a technical evidence audit. It does not establish that an export is licensable, commercially valuable or suitable for every evaluation.

What does Git preserve that a pull request platform adds to?

Git's commit-tree reference describes a commit object built from a tree, with possible parent identifiers and recorded author and committer information. Inspect which of those fields the export preserves. A displayed name or timestamp is repository metadata, not independent verification of a person's identity or authority.

Pull request conversation, changed files and checks are described in GitHub's pull request documentation. Review actions can include comments, approval or requests for changes. These are platform records with their own context. Their existence should not be inferred from the presence of Git commits alone.

GitHub also documents ways to link a pull request to an issue. That establishes a supported platform mechanism, not a guarantee that every pull request has an issue or that a particular export retains the link. Check the actual record before describing the connection as present.

For one case, record each required connection and the observation supporting it. Use separate states for present, absent, excluded and unknown. An item intentionally left out of the permitted scope should not be described as missing from the source system.

Connection to inspect Evidence to look for in the permitted export Unresolved question to retain
Commit to parent and tree Recorded object identifiers and the referenced objects in scope Can the proposed change sequence be reconstructed?
Pull request to revision A retained reference identifying the version being discussed Does the discussion concern this version or an earlier one?
Review comment to context The relevant line, diff or revision reference where retained Is the surrounding code needed to interpret the comment present?
Check to evaluated version A retained version reference, status and available report Is the result tied to the version under review?
Pull request to issue An explicit retained link, when one exists Is the issue available and within the permitted scope?

This table is an audit proposal, not a list of fields every export format must provide. Record the actual format and field names separately. If a relationship is inferred from a title or a date, label it as an inference and explain how it was made.

Can a review comment without its revision explain the final change?

Consider a hypothetical export with a final code snapshot, two review comments and a check marked successful. The comments say that a validation condition needs changing. The export does not identify the revision to which they refer, and the check record does not identify the commit it evaluated.

You can observe that the comments and status exist. You cannot conclude from this export alone that the final snapshot incorporates the requested change or that the successful check evaluated that snapshot. Reading similar wording in the final code may suggest a relationship, but it does not supply the missing version evidence.

The next request should be narrow: ask the responsible party whether the permitted export can include the relevant revision references and the check's version association. If not, narrow the intended use. The material might support a study of review language while remaining insufficient for a task that requires verifying whether a comment was resolved in the tested version.

This is an invented record-audit example. It describes neither an Avelence client nor an observed dataset.

What do approval and successful-check records actually establish?

A review approval establishes that an approval action was recorded in the platform. It is not a finding that the code is correct, that all tests were comprehensive or that the reviewer can license the material. A successful check records a result within whatever scope that check actually had. Its name alone does not explain its coverage.

Keep observation and interpretation in separate fields. For example: observation, a retained check is marked successful; limitation, its underlying report is excluded; next decision, determine whether the status alone is sufficient for the proposed task. This is more useful than converting every successful status into a generic quality label.

Apply the same discipline to absent records. No check in the export means no check evidence was found there. It does not prove that the team never tested the change. Likewise, an absent issue link does not prove there was no requirement elsewhere.

What scope and missing relationships should the audit report?

The audit should name the project scope, selected branches or versions, relevant period, export format and exclusions. Identify the version of the export reviewed. If later preparation removes comments or changes references, review whether the required relationships still survive.

Do not request credentials, private repository access or unrelated source material to fill an evidence gap informally. Any later access or transfer needs its own agreed scope, handling and authority. Recorded authorship, review approval and a technical inventory do not create those permissions.

Conclude with one of three scoped decisions: the export supports the stated question; a specified missing relationship needs review; or the intended question must be narrowed. Keep the observations that led to the decision so another reviewer can understand what was actually established.

For the broader owner-side licensing discussion, see software-development histories. This export audit addresses the narrower evidence question and does not replace the technical, rights or commercial decisions needed for an actual contribution.

A buyer can use the sourcing brief to state the comment-to-revision or check-to-commit relationship needed for its task before asking a source for more material. Specify which missing connection would change the decision; a larger export is not always the answer.
