Key work:
stub-class AST check(drydock/core/tools/builtins/write_file.py) — catches the lang_interp pattern where the model writesclass Interpreter: def run(self): passinline to silence ModuleNotFoundError. Verified against real bug.gemma4.md prompt rule— explicit "never write inline stub classes".auto_generate_tests.py— 6 iterations of heuristic refinement: conservative literal detection, 5 vocabulary expansions (nouns, adjectives, ordinals), multi-slash either-or, /tmp fixture creation, plain-name file fixture seeding, lower "ran cleanly" threshold.BASELINE_412.md— ground-truth baseline across all 99 PRDs.worked_examples/tree_walking_interpreter.py— canonical 3-layer interpreter (lexer → parser → interpreter) with precedence-via- method-nesting and environment-with-outer for lexical scope.worked_examples/cli_subcommand_dispatch.py— canonical argparse subcommand dispatch; prevents the minivc "init.run() on a function" bug.MODEL_SHORTCOMINGS.mdevidence additions:- #2 (scaffolding without wiring): minivc case documented.
- #10b (new): interactive fallback ignoring CLI args (password_vault).
9-phase comprehensive_loop runs with real TUI via pexpect. Validators check real artifacts (PLAN.md, REVIEW.md, tests/, .git, README.md, OPTIMIZATION.md) and run auto-generated functional_tests.sh.

| 27_file_organizer | 2/3 | 3/3 | test-gen lowered threshold + real /tmp fixtures |

| 33_config_manager | 2/4 | 4/4 | test-gen noun-phrase + structure detection |
Caveat: gains are primarily test-generator improvements (better expected-output heuristics) rather than drydock iteration fixes. The config_manager shakedown crashed after phase 1 ("prompt never landed") but the final tests passed because the v1 baseline was using too-aggressive literal matching.
For drydock-iteration gains specifically, the true signal is
Batch v2 — rich-test PRDs where all three completed 9/9 phases with
clean test results, AND file_organizer's phase 2_build rewrote the
package from scratch and produced a 3/3 result.

14 PRDs fully fixed via drydock meta_ralph iteration. 3 stalled (multi-module complexity). Average successful fix time ~3 min. Stage 1 single_build succeeded in 11/14 cases (79%). Stage 2 best_of_2 needed for 3 cases.
The minivc fix is the flagship result: drydock correctly diagnosed
AttributeError: 'function' object has no attribute 'run' as a
scaffold-wiring bug and rewrote __main__.py to call commands as
callables (add_cmd(args.path)) instead of attribute access
(add.run(args.path)) on function imports. The worked example
cli_subcommand_dispatch.py surfaced via keyword match on
"argparse", "subcommand", "init", "run()", "AttributeError".
The lang_interp stall confirms shortcoming #10c: multi-module architectural rewrites (lexer → parser → type_checker → interpreter → repl) exceed 3-stage iteration capacity. Partial fixes get rolled back. Future work needs multi-session checkpointing.
- #7 (web_search) — model still doesn't reach for web tools when stuck. Prompt rule in place but unverified in practice.
- #9 (thinking stall / idle) — phase 9 "optimize" hangs ~1/3 of runs. Shortcoming #10 (weak abstract reasoning) is the root cause; the stall is a symptom.
- #10 (optimize phase) — consistent across passgen, todo_manager, fibonacci_gen. "Optimize" phase treats the instruction as too vague.
- #1 (tool-arg malformation) — hasn't recurred in shakedown batches, but size-sanity guard in search_replace remains the safety net.
BASELINE_412.md— test-by-test baseline with progression table.MODEL_SHORTCOMINGS.md— running log for future fine-tuning.worked_examples/{sql_parser,tree_walking_interpreter,cli_subcommand_dispatch}.py— canonical references surfaced in meta_ralph stuck-mode via keyword matching inworked_examples/lookup.json./tmp/baseline_412/results{1..6}.tsv— TSVs from each generator iteration for reproducibility.
- Review the config_manager shakedown result when it lands.
- Consider running meta_ralph on 10_version_control specifically — it's the canonical shortcoming #2 case and the new cli_subcommand_dispatch worked example is exactly what it needs.
- Unpause auto_release (
rm /data3/drydock/.pause_auto_release) or do a manual publish if you want v2.6.79 on PyPI. - Merge baseline into CI? Currently it's a local-only regression signal.
