Release 0.1.7 by Shashankss1205 · Pull Request #114 · CodeGraphContext/GraphARC

Shashankss1205 · 2026-08-13T19:29:15Z

Two defects closed since 0.1.6, both found by re-verifying a stale bug backlog against main rather than from a report.

admission accepted a sentinel pointing the wrong way (admission: END is accepted as an edge source and START as a target, so a graph that cannot be built is admitted #108 → Admission refuses a sentinel pointing the wrong way #109). END -> x / x -> START was admitted and then died in Materializer, charged to max_consecutive_execution_failures (2) rather than max_consecutive_rejections (3), and reaching the planner as prose instead of a coded rejection.
a dead sandbox child escaped as a bare EOFError('') (harness: a sandboxed child that dies without sending escapes as a bare EOFError, so the agent is told 'TOOL_ERROR:' and nothing else #111 → A sandboxed child that dies without sending names the tool it was running #112), which AgentNode rendered to the model as TOOL_ERROR: with nothing after the colon.

Both shipped with tests that go red without the fix.

Why now

0.1.6 is already on PyPI and a version can only be uploaded once, so the two fixes above are not installable until this goes out.

Verification

uv run pytest green · uv run ruff check . clean. The version moves in the two places CI compares and the six where prose states it; all but the README line are asserted by tests.

Two defects closed since 0.1.6, both found by re-verifying a stale bug backlog against main rather than by a report: - admission accepted `END` as an edge source and `START` as a target, so a graph that cannot be built was admitted and failed in materialisation — charged to the execution-failure allowance rather than the rejection one, and reaching the planner as prose instead of a code and a remedy (#108/#109). - a sandboxed child that died without sending escaped as a bare `EOFError('')`, which the agent loop rendered to the model as `TOOL_ERROR:` and nothing else (#111/#112). The version moves in the two places CI compares and the six where prose states it. `tests/test_deep_dive.py` and `tests/test_cookbook_*.py` assert all but the README line, which is how they stay right.
