When fallback formatting handles an issue whose acceptance criteria lack a recognized gate, this adds a formatter-repository test rather than a verification step for the requested work. For example, an issue asking to update src/client.py now passes the canonical validator solely because tests/scripts/test_issue_formatter.py is named, even though that test cannot verify the client change—and the path does not exist in typical consumer repos. This fabricates readiness and can let automation treat work as complete without any relevant acceptance gate; derive a gate from the issue or leave it non-conforming for refinement instead.

Pull request overview
This PR tightens the contract between the issue-body formatter (scripts/langchain/issue_formatter.py) and the fleet’s canonical validator (.github/scripts/issue_format.py) so the formatter cannot claim output is valid when it would be rejected by the same guard used elsewhere in the automation.
Changes:
- Dynamically loads and reuses the canonical issue-format validator module (including
GATEandvalidate()), instead of re-implementing the gate logic. - Ensures fallback-formatted Acceptance Criteria gets a verification-gate match when missing, and updates
_formatted_output_valid()to fail unlessissue_format.validate(...).okis true. - Expands formatter tests to assert canonical validation behavior and acceptance-gate behavior.

In `@scripts/langchain/issue_formatter.py`:
- Around line 373-379: Update the formatter flow around
_issue_format_validator() to validate the complete body only after every
formatting transformation, including the acceptance-text update, and fail
explicitly when canonical validation fails rather than returning invalid
content. In tests/scripts/test_issue_formatter.py lines 135-136, assert
canonical validity after the production fix or the explicit failure for
placeholder input; at lines 248-252, assert canonical validity for the final LLM
result after raw-issue and reuse-marker processing.
In `@tests/scripts/test_issue_formatter.py`:
- Around line 71-86: Update
test_format_issue_fallback_adds_acceptance_gate_when_only_tasks_have_verify_hint
to assert that acceptance contains the source prose “Formatter preserves the
source acceptance prose.”, alongside the existing command and validation
assertions.

Automated Status Summary
Scope
scripts/langchain/issue_formatter.py(the generator) and its contract with.github/scripts/issue_format.py(the validator). The goal is that a body the formatter returns as valid is a body the validator accepts, so the fleet's own generator cannot file work that the format guard must reject.Context for Agent

Tasks
scripts/langchain/issue_formatter.py, after buildingacceptance_linesat:346, detect whether the assembled Acceptance Criteria section satisfies the same gate the validator applies.
