fe1beef verified | # Build log — 2026-09-09 | |
| Rebuild of all tables from the 1,296 source databases, adding `trajectories.parquet`, | |
| `impressions.slot`, `actions.step`, and correcting the `step` column. | |
| ## Commands | |
| ``` | |
| python build_divdata.py --out divdata/ # 6 core tables, ~2h15 single process | |
| python build_trajectories.py --out divdata/ --workers 16 --patch-steps # trajectories + step back-fill | |
| ``` | |
| Source: `<run>.db` (SQLite, OASIS schema) + `<run>.metadata.json` (agent → model map) | |
| + `<run>_chats.jsonl` (one row per activation: step, status, attempts with the model's | |
| response and tool call) + `<run>_reasoning.jsonl` (thinking channel, where exposed). | |
| 1,384 databases found; 88 skipped (no metadata sidecar, or an in-progress checkpoint). | |

| agents 28847 agents_aligned 26786 (92.9%) agents_multi 339 (see below) | |

| Validation: | |
| - every action in `actions.parquet` is present in `trajectories` (741,219 = 741,219); | |
| - every feed-fetch window holds at most one action in all but 16 runs; | |
| - where `trajectories.step` and the action-count alignment of `posts`/`comments` both give | |
| a value, they agree on 624,776 / 624,820 rows (99.993%); all 44 disagreements are in | |
| 5 of those 16 runs; | |
| - `--patch-steps` back-filled step from the feed-fetch alignment where the action-count | |
| alignment had NULL: posts 15,060 → 8,701 NULL; comments 91,744 → 53,403; actions | |
| 106,264 → 61,564. Agreement on rows both methods covered: 99.995 / 99.993 / 99.993%. | |
| ### The 16 runs with two actions in one feed-fetch window | |
| In decreasing number of extra actions: `archive_20260516_1003/oasis_v9_hetero_late` (2,468 — | |
| an early v9 run whose harness allowed multiple actions per activation), `sweep_olmo_mag_s42` | |
| (98), `sweep_mag_olmo_s42` (97), `tetratic/tetra_s271_r4` (82), `tetratic/tetra_s271_r3` (81), | |
| `attractor_rl/eval_runs_triadic/baseline/eval_baseline_s43` (72), `…_s42` (66), | |
| `tetratic/tetra_s42_r5` (57), `sweep_glm47_glm47_qwe_s137` (51), `sweep_glm47_glm47_qwe_s42` | |
| (36), `sweep_tri_glm_qwe_gem_s999` (36), `sweep_tri_glm_qwe_gem_s271` (32), | |
| `tetratic/tetra_s42_r6` (31), `sweep_tri_gem_mag_glm_s999` (20), `sweep_tri_gem_mag_glm_s271` | |
| (16), `sweep_tri_gem_qwe_glm_s42` (4). For an agent with any such window the refresh alignment is not | |
| trustworthy, so its `step`, `status` and decision fields are NULL in `trajectories` | |
| (339 agents); its actions are all present, extras flagged `extra_in_window=True`, and | |
| `refreshed_at` / `acted_at` are exact. Step coverage in these runs is 0–58%. Prefer | |
| `created_at` ordering there. | |
| ## Erratum in the previous release (published 2026-09-04) | |
| `build_divdata.py` assigned step by iterating all of an agent's posts, then all of its | |
| comments, while the alignment index assumed one time-ordered stream. Consequence, measured | |
| by rebuilding and comparing on the same rows: | |
| | table | rows compared | old step == new step | | |
| |---|---:|---:| | |
| | posts | 74,111 | **38.9%** | | |
| | comments | 560,844 | **49.2%** | | |
| | impressions | per viewer | 0% of viewers had the same step set — every value shifted by one activation (the step-0 intro post has no feed fetch, and was counted as one) | | |
| Agents that only ever commented, and the step-0 intro posts, were correct; everything else | |
| was scrambled. No other column was affected. `actions.step` was NULL throughout in the old | |
| release. Nothing in the accompanying paper used `step`. | |
| ## Decision-record coverage by model (feed-fetch activations) | |
| | model | activations | response_text | reasoning | tool_call | passive | | |
| |---|---:|---:|---:|---:|---:| | |
| | gpt-oss-20b | 247,489 | 0.4% | 4.8% | 94.4% | 0.3% | | |
| | Magistral-Small-2509 | 149,666 | 86.2% | 91.7% | 91.3% | 1.1% | | |
| | Qwen3-32B | 102,546 | 44.6% | 44.7% | 90.2% | 0.3% | | |
| | GLM-4-32B-0414 | 54,430 | 0.0% | 0.0% | 95.7% | 0.6% | | |
| | gemma-4-31B-it | 39,744 | 93.0% | 93.4% | 92.7% | 1.2% | | |
| `tool_call` < 100% because unaligned agents carry no decision record. gpt-oss and GLM-4 | |
| never emit visible deliberation. | |
| ## Addendum 2026-09-28 — `comments.parquet` gains `parent_comment_id` | |
| The simulator records threaded replies (`comment.parent_comment_id`) and the first release | |
| dropped the column. Back-filled from the source databases; no other column, row count, or | |
| order changed. | |
