| # DocDrift bugs: docs-vs-code drifts in 12 Python libraries, found with Beam |
|
|
| DocDrift gives Beam a whole Python library (docs + code, up to ~400k tokens) in one call. A free AST symbol check proposes name and signature mismatches. Beam triages those candidates against the packed repo, can add cross-file or prose drift, and writes a script that runs the documented usage. A finding counts as reproduced only if that script raises TypeError, AttributeError, ImportError, or NameError on a documented-usage line. |
|
|
| This dataset is the recorded output of that pipeline on 12 pinned libraries. 34 real docs bugs were found in 11 of the 12 libraries; 30 reproduce. Labels were checked against the source by an AI reviewer, not a human annotator. The stored field is still named `hand_verdict`. |

|
| ## How it was built |
|
|
| 1. Pin each library to a recorded commit. |
| 2. Pack docs + source up to a 400k token cap. |
| 3. Run a free symbol check, then one whole-repo Beam triage call per library (11 of 12 succeeded in one call; structlog failed; cattrs needed 2). |
| 4. Beam-written repro scripts, plus one hand-written starlette script from Beam's verdict. |
| 5. Citation check is quote alignment of cited lines vs packed source (±3-line shift). It is not a verdict that the drift is real. |
|
|
| ## Configs |
|
|
| | config | rows | what it is | fields | |
| |---|---:|---|---| |
| | findings | 60 | Hybrid method items (the 60 findings) | `repo`, `id`, `kind`, `verdict`, `drift_id`, `beam`, `strict_confirmed`, `repro_status`, `evidence`, `hand_verdict`, `hand_verdict_description` | |
| | triage_verdicts | 56 | Beam triage verdicts (56 judged) | `repo`, `candidate_id`, `source_id`, `verdict`, `reason`, `code_path`, `code_line`, `code_quote` | |
| | repros | 54 | Executable repro cases | `case_id`, `repo`, `status`, `strict_confirmed`, `exception_type`, `error_excerpt`, `evidence` | |
| | planted_drift | 58 | Planted-drift set + ground truth | original probe fields plus `seed` | |
| | ablation_verdicts | 56 | Whole-repo vs local-file vs matched-cost retrieval triage on the same 56 candidates | `key`, `repo`, `candidate_id`, `label`, `hand_verdict`, `hand_verdict_description`, `cross_file`, `gold_outside_local`, `whole_verdict`, `local_verdict`, `matched_verdict`, `stability_verdict`, citation flags | |
| | matched_cost_ext_verdicts | 63 | Scored pre-registered extension items only (63 rows in this file; 49 cross-file, 48 outside-local). Pooled 52/78 includes the original 56 from `ablation_verdicts`; those original rows are not duplicated here. | `key`, `set`, `stratum`, `label`, `hand_verdict`, `cross_file`, `gold_outside_local`, per-arm `whole_` / `local_` / `matched_` verdicts and citations | |
| | beamv3_findings | 115 | Extra 32k-docstring-chunk and docs-pass findings (unlabelled not counted as true) | `id`, `repo`, `pass`, `doc_path`, `doc_line`, `label`, `drift_id`, `label_by`, `hand_verdict`, `hand_verdict_description`, `new_vs_hybrid`, `strict_confirmed`, `explanation` | |
| | token_ledger | 493 | Hybrid + first-sweep + ablation + extra-pass token ledger | original ledger fields plus `ledger` (`first_sweep`, `hybrid`, `ablation`, `beamv3`, `matched_cost`, `matched_cost_ext`, `fresh_run`) | |
|
|
| `hand_verdict` means checked against the source by an AI reviewer. It is not a human annotator. |
|
|
| ## Limits |
|
|
| - The 45-drift universe is the union of method output, so it favours those methods. The 45 true hybrid findings are a different set from those 45 pooled drifts. |
| - 11 of 12 libraries were triaged; structlog failed; cattrs needed 2 calls. |
| - 2 false + 1 unclear received a strict badge (werkzeug S38, S39 false; S41 unclear). |
| - End-to-end including repro is 9,302,105 (~9.3M) = 4,424,575 first sweep + 4,739,392 hybrid triage + 138,138 repro. The first sweep is in `token_ledger` as `ledger=first_sweep` (12 rows from the recorded 400k traces). |
| - Extra experimental runs, not in the 9.3M: ablation 1,948,469; beam v3 7,713,453; matched-cost control 3,957,434; matched-cost extension 7,528,878; tomlkit CLI run 185,842. Matched-cost controls plus the recording: 11,672,154. |
| - Long context did not change verdict accuracy on these 56 candidates; it changed citation grounding. A matched-cost retrieval control (96.7% of whole-repo spend) matched accuracy (46/56 vs 47/56) but not grounding (cross-file 19/30 vs 25/30; McNemar p = 0.070, not shown at this n). Retrieval missed the defining file in 5 of 13 outside-local items. A pre-registered extension added 63 items (57 planted renames, 6 real structlog). Pooled, retrieval grounded 38/78 cross-file cases vs 52/78 for the whole repo (McNemar p = 0.0094). Outside-local: 38/61 vs 25/61 (p = 0.0146). Accuracy still did not differ (105/118 vs 108/119). The new items alone give p = 0.096 (not shown at this n), and the pooled p is 0.18 without one pre-registered parse-failure re-send. Pre-registration: design_ext.md sha256 42f6b6fe…c996. |
| - 32k docstring chunks recovered 7 of 11 hybrid misses; the docs pass recovered 1. New-item precision is a lower bound (18.5% for hybrid + 32k chunks). Headline stays 34 of 45. |
