description	Fix graalvm-reachability-metadata PRs where final validateIndexFiles against current master fails because metadata index.json tested versions are in the wrong metadata-version bucket, duplicated across buckets, or stale after another index-changing PR landed. Use during PR review when an index-changing PR must be repaired and pushed instead of labeled human-intervention.

Fix Index File Inconsistencies

Use this skill while reviewing a PR that changes metadata/<group>/<artifact>/index.json and fails final index validation on current master.

The goal is to repair the PR branch, commit the fix, push it to the same PR, and then continue the review. Do not label the PR human-intervention for fixable index bucket inconsistencies.

What To Fix

validateIndexFiles enforces that each non-latest metadata entry owns only tested versions that belong before the next metadata entry. Common failures:

• A PR was valid when an older entry was latest, but another PR added a newer metadata entry first. The older entry is now non-latest, so the PR's added tested versions must move to a later bucket.
• A tested version appears in an older entry even though the same version has its own metadata entry.
• A tested version was appended to the closest textual entry instead of the compatible metadata-version range.

Fix only the affected index.json files unless the branch must first be rebased onto origin/master so the correct target bucket exists locally.

Reproduce The Final Candidate

From the PR review worktree:

PR_NUMBER=<pr>
git fetch --quiet origin +master:refs/remotes/origin/master
PR_HEAD="$(git rev-parse HEAD)"
TMP="$(mktemp -d)"
git worktree add --detach "$TMP" origin/master
git -C "$TMP" fetch --quiet origin "refs/pull/${PR_NUMBER}/head"
test "$(git -C "$TMP" rev-parse FETCH_HEAD)" = "$PR_HEAD"
git -C "$TMP" merge --no-commit --no-ff FETCH_HEAD
(cd "$TMP" && ./gradlew validateIndexFiles -Pcoordinates=all --stacktrace)
git worktree remove --force "$TMP"

Read the validation errors. They usually name the library coordinate and the specific tested versions that exceed the next metadata-version boundary.

Repair The PR Branch

The review worktree starts in detached HEAD. To push a fix, check out the PR branch only after you have confirmed this is a fixable index inconsistency:

PR_NUMBER=<pr>
gh pr view "$PR_NUMBER" --json headRefName,headRepositoryOwner,isCrossRepository
gh pr checkout "$PR_NUMBER"
git fetch --quiet origin +master:refs/remotes/origin/master
git rebase origin/master

If the PR is from a fork and you cannot push to it, request changes with the validation error and the exact index repair needed. Do not add human-intervention.

Edit the affected index.json files:

• Move tested versions from the older metadata entry into the correct later entry when the validator says they are greater than or equal to the next metadata-version boundary.
• Remove a tested version from an older entry when that version already has its own metadata entry.
• Preserve URL fields, allowed-packages, requires, latest, and metadata-version unless the validator error directly proves one is wrong.
• Preserve the file's existing JSON formatting and version ordering style.

Validate the repair:

./gradlew validateIndexFiles -Pcoordinates=all --stacktrace

Then commit and push:

git diff
git add metadata/<group>/<artifact>/index.json
git commit -m "Fix index version buckets"
git push --force-with-lease

After pushing, submit the GitHub review. If the fix is complete and no other blocking issues remain, approve with a short note that the index bucket repair was pushed and full index validation now passes.

Examples

Stale latest bucket

An older Jetty entry was once latest, so a PR appended 9.4.1 through 9.4.7 there. After another PR added a Jetty 9.4.8 entry, the old entry was no longer latest, and the validator rejected the 9.4.x tested versions under the 9.3.x metadata bucket.

Fix: move 9.4.1 through 9.4.7 from the 9.3.19.v20170502 entry into the 9.4.0.v20180619 entry, leaving the 9.3.x tested versions in the older entry.

Duplicate tested version

A Camel entry for 4.19.0 contained:

"tested-versions" : [
  "4.19.0",
  "4.20.0"
]

but 4.20.0 already had its own metadata entry.

Fix: remove 4.20.0 from the 4.19.0 entry. Do not delete the 4.20.0 metadata entry.

Review Decision

• If the index repair validates and the rest of the PR is clean, approve.
• If the index repair exposes unrelated contamination, request changes for the unrelated issue.
• If the branch cannot be pushed, request changes with the exact repair instructions.
