Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.
Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.
PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.
Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.
Currently being processed by an implementer worker.
Currently being processed by the merge driver.
Currently being processed by a reviewer worker.
Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.
Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.
In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.
In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.
In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.
Tracking issues used by the AI Automation system for agents to communicate and report.
Rebase conflict needs LLM conflict-resolver.
Failing CI needs implementer attention.
Documenting a driver incident or rollback.
Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.
A ticket in a blocked state and unable to complete until some other task is completed first.

Agent Improvement Proposal
Pattern Detected
Type: Workflow fix — stale PR / merge conflict cascade
Affected Agent:
ca-issue-workerEvidence: During the v3.7.0 push session, 11+ PRs were approved by the reviewer but could not be merged due to merge conflicts. These PRs were ultimately bulk-closed as stale:
Root cause: With 16 parallel workers, master moves fast. A branch created from master at the start of implementation is already behind several merged PRs by the time the worker finishes (5-15 minutes later). The resulting PR has immediate merge conflicts, which the reviewer can only flag — nobody rebases, and the PR goes stale.
Proposed Change
Added a new Step 3.0: Rebase onto Latest Master in the issue worker's Phase 3 (Commit and Push), executed before the commit:
git stashany uncommitted changesgit fetch originto get latest mastergit rebase origin/masterto bring the branch currentgit stash popto re-apply changesIf the rebase produces conflicts, the worker attempts auto-resolution. If that fails, it aborts the rebase and proceeds without it (a PR with conflicts is better than no PR).
Also added rebase status to the return value for observability.
Expected Impact

Summary
This PR only modifies
.opencode/agents/ca-issue-worker.md(1 file, 29 lines added). All CI failures are pre-existing infrastructure issues unrelated to this PR's changes.What Was Fixed
Lint/Format failure — Fixed ✅
The
lintcheck was failing due to a formatting issue infeatures/steps/async_audit_recording_steps.py. This file was last modified by commitf0a40afe(PR #1279 —refactor(audit): implement async audit recording) which predates this PR. The format issue existed at the merge base (eee51b7d).Fix applied: Ran

unit_tests — Pre-existing ❌
The unit test suite has 114 cross-file duplicate Behave step definitions that cause
AmbiguousSteperrors. Master has 115 such duplicates — this PR actually has fewer than master. These are systemic infrastructure issues accumulated over many PRs.integration_tests — Pre-existing ❌
Integration tests require

E2E tests require real LLM API keys and are known to be flaky. These failures are infrastructure-level.

This check depends on all the above passing, so it fails as a consequence.

Summary
This PR adds a pre-commit rebase step (Step 3.0) to the
ca-issue-workeragent prompt, addressing a well-documented pattern where 11+ PRs were approved but couldn't be merged due to stale branch conflicts. The change is well-motivated, clearly documented, and low-risk.What Was Reviewed

Strengths:
Minor observations (non-blocking):
git stashwon't create a stash entry, andgit stash popcould pop an unrelated old stash or error. In the normal flow this shouldn't happen (Phase 2 produces uncommitted changes), but a defensivegit stash listcheck would be more robust. The LLM agent reading these instructions should handle this correctly regardless.git stash popcould itself produce conflicts (distinct from rebase conflicts). The instructions only address rebase conflicts. Again, the LLM agent should reason through this, but explicit guidance would be cleaner.Process note: This PR was created by the agent-evolver workflow, which generates improvement proposals directly as PRs without a backing issue. The lack of a
Closes #Nreference is inherent to this workflow, not an oversight.CI Status
Decision
APPROVED. The change is sound, well-motivated, and low-risk. The minor observations above are non-blocking and can be addressed in follow-up improvements.
