-`dev/dev-poll.sh` — Cron scheduler: finds next ready issue, handles merge/rebase of approved PRs, tracks CI fix attempts. `BOT_USER` is resolved once at startup via the Forge `/user` API and cached for all assignee checks. Formula guard skips issues labeled `formula`, `prediction/dismissed`, or `prediction/unreviewed`. **Race prevention**: checks issue assignee before claiming — skips if assigned to a different bot user. **Stale branch abandonment**: closes PRs and deletes branches that are behind `$PRIMARY_BRANCH` (restarts poll cycle for a fresh start). **Stale in-progress recovery**: on each poll cycle, scans for issues labeled `in-progress`. If the issue is assigned to `$BOT_USER` (this agent), checks for pending review feedback first — if an open PR has `REQUEST_CHANGES`, spawns the dev-agent to address it before setting `BLOCKED_BY_INPROGRESS=true`; otherwise just sets blocked. If assigned to another agent, logs and falls through (does not block). If no assignee, no open PR, and no agent lock file — removes `in-progress`, adds `blocked` with a human-triage comment. **Per-agent open-PR gate**: before starting new work, filters open waiting PRs to only those assigned to this agent (`$BOT_USER`). Other agents' PRs do not block this agent's pipeline (#358, #369). **Pre-lock merge scan own-PRs only**: the direct-merge scan only merges PRs whose linked issue is assigned to this agent — skips PRs owned by other bot users (#374).
**FORGE_REMOTE**: `dev-agent.sh` auto-detects which git remote corresponds to `FORGE_URL` by matching the remote's push URL hostname. This is exported as `FORGE_REMOTE` and used for all git push/pull/worktree operations. Defaults to `origin` if no match found. This ensures correct behaviour when the forge is local Forgejo (remote typically named `forgejo`) rather than Codeberg (`origin`).
**Session lock**: fd-based flock — released during idle phases (`awaiting_review`, `awaiting_ci`) so other agents can proceed; re-acquired before injecting the next prompt. This prevents the lock from blocking the whole factory while the dev session waits.
**Crash recovery**: on `PHASE:crashed` or non-zero exit, the worktree is **preserved** (not destroyed) for debugging. Location logged. Supervisor housekeeping removes stale crashed worktrees older than 24h.
