Motivation

weekly-rebuild-reindex exists to run after weekly-rebuild-missing: it declares depends_on: weekly-rebuild-missing and is gated on that workflow's weekly_rebuild_missing variable. Triggering it manually therefore also starts hours of package rebuilds.

That is the wrong tool when only the index needs regenerating. After rpkgs/bincraft#113 (v5.1.5), which changes how union_index_records() decides what a per-minor index steers to, every object in the bucket is already correct and only PACKAGES* is stale. Rebuilding to fix an index is pure waste, and the natural cron would take a full cycle to reach every slot.

Change

Adds .crow/reindex.yaml: the index half on its own, manual only, no dependency on a rebuild.

It reuses the same matrix and the same steps as weekly-rebuild-reindex — install the latest bincraft release, republish the generic index, loop the installed R versions republishing each per-minor index, purge the edge. No package is built.

Gated on a new reindex variable so it cannot be started by the rebuild gate, defaulting to none so a manual pipeline creation (which instantiates every file in .crow/) matches no matrix row.

crow pipeline create devxy/build-cran-binaries --var reindex=all
crow pipeline create devxy/build-cran-binaries --var reindex=ubuntu-2404-amd64

Verification

• crow lint .crow/ passes.
• Gate is manual-only and evaluates reindex, with no depends_on and no runs_on carried over from the rebuild coupling.

## Motivation `weekly-rebuild-reindex` exists to run after `weekly-rebuild-missing`: it declares `depends_on: weekly-rebuild-missing` and is gated on that workflow's `weekly_rebuild_missing` variable.

After rpkgs/bincraft#113 (v5.1.5), which changes how `union_index_records()` decides what a per-minor index steers to, every object in the bucket is already correct and only `PACKAGES*` is stale. Rebuilding to fix an index is pure waste, and the natural cron would take a full cycle to reach every slot. ## Change Adds `.crow/reindex.yaml`: the index half on its own, manual only, no dependency on a rebuild.

ci: add a reindex-only manual workflow ... a114421631

weekly-rebuild-reindex depends on weekly-rebuild-missing and shares its
gate, so triggering it manually also starts hours of package rebuilds.
That is the wrong tool when only the index needs regenerating: after a
bincraft release that changes how the index is written, the objects in
the bucket are already correct and only PACKAGES* is stale.

This workflow does the index half alone. It installs the latest bincraft
release, republishes the generic and per-R-minor indexes for each slot,
and purges the edge. No package is built.
