From 074b9e02e210f4cdc933f554a0b0e67c2aca7d54 Mon Sep 17 00:00:00 2001 From: Patrick Buckley Date: Wed, 29 Jul 2026 19:08:13 -0700 Subject: [PATCH] feat(eval): cells seed the tool-visible world through production writers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Every surface the model can observe must agree about the world's age and contents. The C1 confirm at n=25 measured models sweeping memory, skills, and list_nodes, finding voids that contradicted a transcript full of referents, and spawning read-only investigators to resolve the contradiction — the forbidden rate was measuring the fixture's hollow tool-world, not dispatch discipline. A cell's world block seeds structured memory rows through the same upsert the memory tool's save action commits (names normalize exactly as model-saved rows do), and node rows through the service registry plus node metadata — the two reads list_nodes intersects, so a seeded node is live inside the heartbeat window by construction. A seed failure raises; a malformed world block is refused at config time before the canary, with its own trip cell in the reachability guard. The approval-stop cell gains the first world: two process-fact memory rows (no coaching — the reservation lives in the transcript only) and one live node. --- tests/test_eval_nudges.py | 61 ++++++++++++++++++++++- turnstone/eval/nudges.py | 79 ++++++++++++++++++++++++++++++ turnstone/eval/scenarios/nudges.py | 42 ++++++++++++++++ 3 files changed, 180 insertions(+), 2 deletions(-) diff --git a/tests/test_eval_nudges.py b/tests/test_eval_nudges.py index f6f4b11d..a86817d6 100644 --- a/tests/test_eval_nudges.py +++ b/tests/test_eval_nudges.py @@ -48,6 +48,7 @@ from turnstone.eval.nudges import ( _seed_child_transcripts, _seed_tasks, _seed_transcript, + _seed_world, _StubCoordinatorClient, _validate_cells, build_stimulus, @@ -147,6 +148,14 @@ def _trip_cells() -> list[dict[str, Any]]: "children": [{"ws_id": "ws-c1", "name": "auditor", "state": "idle"}], "tasks": [_OPEN_TASK], }, + # A world block with an unrecognized key — a silent no-op seed — + # trips only the world-shape check. + { + "id": "X_t", + "arms": [ARM_NUDGE], + "tasks": [_OPEN_TASK], + "world": {"memroy": []}, + }, ] @@ -231,6 +240,55 @@ class TestCellFixtures: _seed_tasks(client, "coord-eval-1", bad) +class TestWorldSeeding: + """``world`` seeds the TOOL-VISIBLE environment through production + writers, and the proof is the production READS: the memory rows come + back through the same listing the memory tool serves, and the node + comes back through the real ``CoordinatorClient.list_nodes`` — the + service-registry liveness intersection included.""" + + _WORLD_CELL = { + "id": "X_world", + "tasks": [{"title": "t", "status": "pending"}], + "world": { + "memory": [ + { + "name": "proj-context", + "content": "acme-api: staging tracks main.", + "type": "reference", + } + ], + "nodes": [{"node_id": "node-t", "metadata": {"hostname": "node-t", "os": "linux"}}], + }, + } + + def test_memory_rows_read_back_through_the_production_listing(self, eval_storage): + from turnstone.core.memory import list_structured_memories + + _seed_world(eval_storage, self._WORLD_CELL) + rows = list_structured_memories(scope="global") + by_name = {r["name"]: r for r in rows} + # The production writer normalizes names (normalize_key), so the + # seeded row reads back exactly as a model-saved one would. + assert "proj_context" in by_name + assert by_name["proj_context"]["content"] == "acme-api: staging tracks main." + + def test_nodes_read_back_through_the_real_list_nodes(self, eval_storage): + _seed_world(eval_storage, self._WORLD_CELL) + client = _StubCoordinatorClient( + eval_storage, coord_ws_id="coord-eval-1", user_id="eval-user" + ) + out = client.list_nodes() + ids = {n.get("node_id") for n in out.get("nodes", [])} + assert "node-t" in ids + + def test_a_worldless_cell_seeds_nothing_and_raises_nothing(self, eval_storage): + from turnstone.core.memory import list_structured_memories + + _seed_world(eval_storage, {"id": "X_plain", "tasks": []}) + assert list_structured_memories(scope="global") == [] + + class TestSweepValidation: """Every fixture error a cell can carry is refused at config time — before the canary probe spends a model round-trip — because each of @@ -1255,8 +1313,7 @@ class TestStimulus: ) idle_body = _body([{"ws_id": "ws-c1", "name": "auditor", "state": "idle"}]) assert ( - "Child ws-c1 has stopped — " - "wait_for_workstream returns immediately for it." + "Child ws-c1 has stopped — wait_for_workstream returns immediately for it." ) in idle_body assert "Child " not in _body([{"ws_id": "ws-c1", "name": "auditor", "state": "closed"}]) # No hedge about an observed state, in any cell class. diff --git a/turnstone/eval/nudges.py b/turnstone/eval/nudges.py index eb5ed119..31c38f12 100644 --- a/turnstone/eval/nudges.py +++ b/turnstone/eval/nudges.py @@ -79,6 +79,7 @@ from turnstone.console.coordinator_idle_observer import ( from turnstone.core import metacognition as _metacog from turnstone.core.child_event_bus import ChildEventBus from turnstone.core.log import get_logger +from turnstone.core.memory import save_structured_memory from turnstone.core.metacognition import ( field_str, format_idle_children_nudge, @@ -789,6 +790,46 @@ def _seed_transcript(case: dict[str, Any]) -> list[dict[str, Any]]: return out +def _seed_world(storage: Any, case: dict[str, Any]) -> None: + """Seed the cell's TOOL-VISIBLE environment through production writers. + + Every surface the model can observe must agree about the world's + age and contents.
