The script that turns regional rehoming on checks that every cell name it is given looks right. That check only knew about cells numbered up to 29. Production now has cell 30, so the check refused a correct list and the enable step stopped.

What Changed

Before: running "Operate Relay Production Rehome" with mode=enable and the current general cell list failed at "Apply exact durable regional rehome enable" with selector membership is invalid. The monitor workflow accepted the same list, so the two workflows disagreed.

After: the operator script accepts any production-gce-c<N> from 1 to 99 written without a leading zero, so the list that includes c30 passes. It still refuses an empty list, duplicate cells, c0, c100, c09, and names from other environments.

Mechanism: the membership check in cloud/dev/scripts/operate-relay-regional-rehome.mjs used a pattern that spelled out 1-9 and 10-29. It now uses one named pattern for 1-99.

Why

A list of allowed numbers has to be edited every time a cell is added, and forgetting it blocks an audited production step. A two-digit bound still rejects typos and junk while leaving room for new cells. The director remains the real authority: the script compares the given list against the live selector before changing anything, so a looser shape check cannot enable a wrong membership.

Visual Proof

N/A. This is an operator script with no UI.

Testing

• I manually tested these changes locally
• Automated tests added/updated, or explained why not below

A new test checks that c9, c29, c30 and c99 are accepted and that c0, c100, c09, a duplicate, a staging name, and an empty list are rejected. It fails against the old pattern and passes with the fix. The rehome operator, rehome workflow, and rehome trust probe test files all pass under node --test.

Review

Agent skill upstream boundary

• Not applicable, or this change follows docs/reference/agent-skill-sharing-upstream-boundary.md and copies or mechanically translates no upstream skill-installer source, tests, fixtures, registry entries, path tables, comments, or documentation.

Notes

No desktop, mobile, SSH, or cross-platform surface. The script only runs in the production rehome workflow.

Checklist

• This PR is small and focused
• I explained what changed and why (ELI5, the user-facing before/after, the mechanism, and why over the alternatives)
• Before/after screenshots or videos attached for UI changes, or N/A with reason
• Self-reviewed for correctness, security, and performance
• Cross-platform, SSH/remote, and path/shortcut impact considered (or N/A)
• pnpm lint, pnpm typecheck, pnpm test, and pnpm build pass (or CI will cover; local preferred)

Reviewed changes

• Widen the operator's cell shape check — operate-relay-regional-rehome.mjs replaces the inline c1–c29 regex with a named PRODUCTION_CELL_ID = /^production-gce-c[1-9][0-9]?$/, so production cells up to c99 parse while c0, c100, leading-zero, duplicate, empty, and non-production names still fail.
• Pin the new boundary with a test — operate-relay-regional-rehome.test.mjs adds coverage that accepts c9/c29/c30/c99 and rejects c0/c100/c09/a duplicate/staging-gce-c30/an empty list.

I confirmed the PR's safety argument independently: the shape check is argument hygiene only, and operateRegionalRehome still requires exactMembership against the live selector before any mutation (operate-relay-regional-rehome.mjs:272-276), so the looser bound cannot enable a wrong membership. I also verified why the monitor accepted the same list and the operator did not — the monitor validates against its configured cell set rather than a shape regex (cloud/apps/relay-ops/src/incident-monitor-cli.ts:156-174). The new assertions do fail under the old pattern (c30/c99 would throw), and the file passes under node --test.

📝 Walkthrough

Walkthrough

The production cell validator now accepts IDs from production-gce-c1 through production-gce-c99, without leading zeroes. A new test checks accepted IDs and rejects zero, out-of-range, zero-padded, duplicate, staging, and empty membership values.
