What changed: Carries #227's reviewed negative-result gate, Issue-owner rule, fixtures, and regression tests onto the integration train.
Why: #227 conflicts with main, and component version bumps would cross tonight's release and marketplace Human Gate.
So what: The coordinator reviews and integrates this internal checkpoint; the final PR to main owns the single version transition and closing linkage.

Part of #226.
Supersedes #227 for the train. #227 stays open for the coordinator to close.

Elon record

Requirements and who asked: The user requested the five reviewed content files from #227 on integration/backlog-2026-10-18, complete suites, and an unversioned WIP checkpoint. This advances the Objective's verified delivery loop without crossing release authority.
Deleted: All source version, plugin mirror, versionctl pyproject, and changelog version changes are excluded; no added design or behavioral changes.
Bottleneck: The reviewed PR cannot join the train while conflicting with main; extracting its content avoids an unauthorized release transition.
Checked myself: Verified live #227 head 9672e94, clean assigned worktree at base 2f04c90, all five carried files byte-for-byte equal to that reviewed head, matching aggregate patch IDs, and complete suite output below.

Candidate and content equivalence

• Base: integration/backlog-2026-10-18 at 2f04c90a926a986f82ebba00971cfb5f98ffbe01.
• Head: 7ebd013593eb9cac6f1e7053588c1584868e09bb.
• Branch: fix/226-negative-result-gate-train.
• Exclusive workspace: /home/luke/.t3/worktrees/agentsmd/fix-226-negative-result-gate-train.
• Exactly five content files changed; no VERSION, plugin.json, pyproject.toml, CHANGELOG, or global/AGENTS.md changes.
• The patch applied cleanly. No non-trivial conflict decision or reviewed meaning change was necessary. Current procedures/ paths and “read in full” wording are preserved.

git range-diff 9672e94~4..9672e94 2f04c90..HEAD -- <five content paths> pairs f89c034 with the single WIP commit and shows caf7e15, b8c6b89, and 9672e94 folded into it. Its displayed differences are the subsequent source commits being squashed, not lost content. Both aggregate content patches have stable patch ID 2f6f4b82bdc1699ae54a8cc246629654f8d078a6. git diff 9672e94 HEAD -- <five content paths> is empty; direct byte comparisons pass for all five files.

Proof

On exact head 7ebd013593eb9cac6f1e7053588c1584868e09bb:

$ python3 -m unittest discover -s tests -p 'test_*.py'
Ran 428 tests in 219.093s
OK

$ python3 -m unittest discover -s tools/versionctl/tests -p 'test_*.py'
Ran 7 tests in 6.810s
OK

The repository suite emitted a non-failing ResourceWarning: unclosed file from existing docs/work/164-trigger-audit/trigger_test.py:1027. No test failed.

git diff --check 2f04c90 HEAD passes. These deterministic checks verify the instruction package and declared contracts. Behavioral Live Verification remains pending normal real-project use.

Delivery state

Internal component checkpoint under version-control decision-tree case 2, committed with VERSIONCTL_WIP=1 and wip: prefix. No version bump, merge, release, publication, or installation performed. Existing Sol/Grok review belongs to source head 9672e94; exact-head review of this train candidate remains with the coordinator.

CI validate is expected to fail at Validate version transition from exact base because this component deliberately has no version transition. This expected failure does not claim a complete merge gate or waive exact-head review. Observed CI state at handoff: validate queued, Version check run 39168039796. No CI failure has been observed. PR is mergeable against its integration base; exact-head independent review remains pending.

Website impact: none, because no public page, setup step, or URL changes.

Review: Luna (codex gpt-6-luna, medium) on 7ebd013

Verdict: pass. No blocking findings.

Note tests/test_negative_result_gate.py:65-101: these assertions require entire prose clauses and exact wording, including the unrelated uniqueness/count check for “Validate at safe boundaries and before reporting.” A valid wording edit or equivalent phrasing will break the test without changing the gate. Prefer checking requirement-level markers or a structured contract so the regression protects behavior rather than the current prose.

Checks: python3 -m unittest discover -s tests -p 'test_*.py' on exact head 7ebd013593eb9cac6f1e7053588c1584868e09bb passed (428 tests). Review found no em dashes. Prior #227 review points remain resolved in this candidate; no blocking mismatch found against Issue #226 scope or surrounding orchestration/core guidance.
