Two-machine runner pool (node + workstation) with claim-based balancing #32
Description
Goal
Run headlesscode runners on both the home node (joe@192.168.1.252) and the workstation, with jobs going to whichever machine has capacity.
Context
- Intake already exists via the GitHub label watcher (
src/watcher/); jobs are issues. - Proposed design: both machines run the watcher and claim up to a per-machine capacity cap (no central balancer, no new infra, no firewall changes).
- Alternative: central dispatcher on the workstation SSH-dispatching to the node. Decision needed (tracked separately).
Acceptance
- Runner install/runbook for the node (node tool, git, gh, headlesscode deps).
- Per-machine capacity cap (max concurrent jobs) in config.
- Claim discipline documented (assignee = claimed; stale-claim recovery).
- Either: claim-based balancing implemented, or dispatcher implemented per decision.

Decision (owner, 2026-10-09): claim-based runners. Both machines run the watcher and claim up to a per-machine capacity cap. Central dispatcher alternative is dropped.

Claim-based capacity, atomic claim refs, epoch fencing, stale-claim quarantine, and the node runbook shipped in v1.7.0. The latest read-only check of the requested second machine found
node,git, andghunavailable on its PATH, the requested checkout absent, and neither a GitHub environment credential nor a gh auth configuration present. No second live runner has been qualified. This issue remains open for node toolchain and scoped credential provisioning, followed by a real two-machine claim/capacity test.w4ffl35 commentedon Oct 12, 2026
The node now has an unprivileged Node 22.23.3, Git 2.47.3 and GitHub CLI 2.46.0 toolchain, plus a locked HeadlessCode checkout. The claim/capacity and worker credential-exclusion tests passed.
An actual two-host synthetic qualification also passed: both hosts contended for atomic claim refs, respected a capacity of one each, renewed leases through six sweeps, excluded credentials from injected worker environments, and rejected stale recovery before accepting a fenced epoch change. The callbacks were synthetic; no model worker or permanent watcher deployment was exercised.
PR #98 fixes discovery starvation when another node owns the first issue in the queue. It is merged. Permanent node deployment and a credentialed issue-to-PR run remain unqualified because scoped node GitHub credentials and the contained worker deployment have not been provisioned. Workstation credentials were not copied to the node.

Files changed
Baseline (before)
Claim-based balancing already in-tree (commits 7a18bc8, 67c0fbf, 1808667, 46cf165 all ancestors of HEAD): GitHub-ref CAS claims, pool-mode sweep/capacity/reconciliation, --runner-id/--runner-assignee CLI + lock. Gap: lease duration not tunable from CLI (claimLeaseMs existed in WatcherConfig but had no flag/env); no dedicated node install runbook.
Baseline (after)

N/A — watcher change needs a GitHub token + live repo to boot a sweep; verified via --help output, parse checks, and typecheck + unit suites instead.

Reopening: PR #124 is not merged yet. The worker closed this issue immediately after filing the PR, but the harness review did not run (reviewer reported 'no real changes' despite the branch commit) and QA did not run. Re-close on merge.
