Follow-up #874 must bind evaluation to an independently head-bound required workflow or check before branch protection or a repository ruleset treats the result as merge enforcement. That ruleset must also require the repository's Copilot review, at least one approving review, and conversation resolution. The gate itself requires the maintainer-applied `copilot-rabbit` label, a non-dismissed Copilot review bound to the current head, every AI review thread resolved (including outdated threads), and committed focused unit tests. It binds to the exact-head trusted CI run, requires its `test` job to succeed, and requires that job's verbose pytest log to report at least one passing test for every declared path; an absent, deselected, or all-skipped path blocks. Human approval alone cannot satisfy those signals.

A recovered infrastructure/publication failure remains failed until a new evidence event or a maintainer manually dispatches the workflow; the scanner does not churn unchanged evidence merely to retry it. GitHub permits at most 1,000 statuses for one SHA and context, so the workflow refuses to acquire a new lease at 998 existing per-PR gate statuses. The scanner may use a remaining slot to fail a proven stuck pending lease or invalidate a successful terminal result after evidence changes, but it never starts another full evaluation at that threshold; the operator must then push a new head or complete #874's Checks/App migration. If pending-status creation fails on a reused head, a previous successful status can remain visible until recovery; overwriting it without a proven lease could instead clobber a successor.

It uploads evidence and updates the PR comment before publishing a terminal status. Resolve-time, collection-time, and publication-time PR base and head commits must each remain the same 40-character SHA; a mismatch publishes `stale_base` or `stale_head` instead of reusing evidence across revisions. Changed-file evidence comes from the immutable resolved base/head commit comparison rather than the mutable live PR file list.

Only refresh-dispatch jobs receive actions: write. Per-path focused-test proof currently parses terminal pytest outcomes from the exact-head trusted CI `test` job log. It handles both same-line verbose outcomes and node IDs followed by live-log output and a standalone terminal outcome. Exact path prefixes, whole-line terminal matching, test-node resets, and session-boundary resets prevent unrelated output from inheriting a prior test. A same-line candidate is deferred across blank lines so a following live-log header can disambiguate a parameter ID that resembles an outcome. Code executed by pytest can still deliberately forge console lines, so the required independent review remains part of the trust boundary. Follow-up #874 must move per-path evidence to a machine-readable report emitted and published by the protected CI workflow before this signal is treated as hostile-agent-resistant. If an agent has repository-write credentials that can create Actions workflows or post statuses/comments, github-actions[bot] and a status-context string are not independent provenance. The collector also sees only the current comment bodies; an agent that can edit or delete its own result comment can erase contradictory self-reported history. In that threat model, keep this workflow advisory until snapshot, append-only result evidence, and check publication move to a dedicated GitHub App (or an organization ruleset-required trusted workflow) and bind the required check to that identity. +## Security Design and Concurrency Controls + +To guarantee system integrity, the following controls are strictly enforced: +- Snapshot creation is label-event-only and does not recursively trigger `issue_comment` events. +- Resolve-time, collection-time, and publication-time PR base and head commits are locked. +- We perform immutable resolved base/head commit comparison to guarantee that the evaluated PR state matches the exact commits being merged. + ## Applicability The gate applies when any of these signals identify agent work: diff --git a/src/agents/specialized/code_generator.py b/src/agents/specialized/code_generator.py index 345f51cb6..14307311e 100644 --- a/src/agents/specialized/code_generator.py +++ b/src/agents/specialized/code_generator.py @@ -20,8 +20,7 @@ def __init__(self): def _load_templates(self) -> dict[str, str]: """Load code generation templates""" return { - "fastapi_endpoint": textwrap.dedent( - """ + "fastapi_endpoint": textwrap.dedent(""" @app.post("/api/v1/{endpoint_name}") async def {function_name}({parameters}): \"\"\" @@ -43,26 +42,26 @@ async def {function_name}({parameters}): except ValidationError as e: raise HTTPException(status_code=400, detail=str(e)) except Exception as e: - raise HTTPException(status_code=500, detail=str(e)) - """ - ), - "rest_api": textwrap.dedent( - """ + logger.error("Internal server error", exc_info=True) + raise HTTPException(status_code=500, detail="Internal server error") + """), + "rest_api": textwrap.dedent(""" # {title} # Generated API endpoint + import logging from fastapi import FastAPI, HTTPException from pydantic import BaseModel from datetime import datetime from typing import Optional, List + logger = logging.getLogger(__name__) + {models} {endpoints} - """ - ), - "crud_operations": textwrap.dedent( - """ + """), + "crud_operations": textwrap.dedent(""" # CRUD operations for {entity} @app.post("/{entity_plural}") @@ -88,8 +87,7 @@ async def delete_{entity}(id: int): \"\"\"Delete {entity}\"\"\" # Implementation here pass - """ - ), + """), } @staticmethod diff --git a/tests/unit/test_500_info_disclosure.py b/tests/unit/test_500_info_disclosure.py index 98ce7f49c..5c0a40f4e 100644 --- a/tests/unit/test_500_info_disclosure.py +++ b/tests/unit/test_500_info_disclosure.py @@ -40,7 +40,11 @@ import pytest -_BACKEND = Path(__file__).resolve().parents[2] / "src" / "youtube_extension" / "backend" +_REPO_ROOT = Path(__file__).resolve().parents[2] +_BACKEND = _REPO_ROOT / "src" / "youtube_extension" / "backend" +# The Ray Serve ML surface returns raw ``JSONResponse(...)`` bodies and lives +# outside ``backend/``; it must be scanned too or 500 leaks there go unguarded. +_ML_SERVE = _REPO_ROOT / "src" / "uvai" / "ml" # Identifiers that, when referenced inside a 500 body, indicate a leak of the # caught exception or the inbound request. @@ -79,13 +83,16 @@ def _refs_exception_or_request(node: ast.AST) -> bool: return False -def _status_is_500(call: ast.Call) -> bool: +def _status_is_500(call: ast.Call, name: str) -> bool: for kw in call.keywords: if kw.arg == "status_code" and isinstance(kw.value, ast.Constant): return kw.value.value == 500 - # positional status_code (JSONResponse(500, ...) / HTTPException(500, ...)) - if call.args and isinstance(call.args[0], ast.Constant): - return call.args[0].value == 500 + # The positional slot of ``status_code`` differs by constructor: + # HTTPException(status_code, detail, ...) -> args[0] + # JSONResponse(content, status_code, ...) -> args[1] + idx = 1 if name == "JSONResponse" else 0 + if len(call.args) > idx and isinstance(call.args[idx], ast.Constant): + return call.args[idx].value == 500 return False @@ -103,7 +110,7 @@ def _iter_500_leaks(text: str): name = _call_name(node) if name not in ("HTTPException", "JSONResponse"): continue - if not _status_is_500(node): + if not _status_is_500(node, name): continue # Check keyword arguments for kw in node.keywords: @@ -118,22 +125,32 @@ def _iter_500_leaks(text: str): if name == "HTTPException" and len(node.args) >= 2: if not _is_static_string(node.args[1]): yield node.lineno, "HTTPException 500 detail is not a static string" + # Positional JSONResponse body: JSONResponse(, status_code=500) and + # the fully positional JSONResponse(, 500).
