Staged-but-not-yet-fixed file artifacts from the post_module_taxonomy_de_cruft
followup. These are mostly minor — direct-import migrations that landed in the
prior commits were not applied to a few remaining files because the broken-script
placement issues were non-trivial.
For Tier 1 followup:
- src/commands.py — unused 'from src import models' removed by migration
- src/mcp_client.py — verified to no longer have the circular self-import
- src/models.py — clean 38-line final state (Metadata alias + PROVIDERS lazy __getattr__)
- src/multi_agent_conductor.py, src/project_manager.py, src/rag_engine.py
— bare 'from src import models' lines replaced with direct imports
- 12 test_*.py files — direct imports of moved classes added (FileItem,
Ticket, MCPServerConfig, MCPConfiguration, load_mcp_config, RAGConfig,
VectorStoreConfig, NamedViewPreset, ContextFileEntry, ContextPreset,
Persona, BiasProfile, parse_history_entries)
- docs/type_registry/src_mcp_client.md — regenerated via type_registry script
No production behavior changes here. These are the residual direct-import
migrations the migration script already completed. Some are tracked in the
end_of_session report for Tier 1 followup.
Per post_module_taxonomy_de_cruft_20260627 Phase 2 (FR7 continued).
The previous migration commit (8f11340b) handled the
'from src.models import X' pattern (85 sites). This commit handles
the 'models.<moved_class>' attribute access pattern (44 sites in 20
files), which the __getattr__ shim previously supported.
The migration was performed by the one-time script
scripts/tier2/artifacts/post_module_taxonomy_de_cruft_20260627/migrate_models_attr.py
which:
1. For each 'models.<moved_class>' reference, replaces it with the
bare class name (e.g., 'models.MCPConfiguration' -> 'MCPConfiguration')
2. Adds the import 'from src.<destination> import <moved_class>' at
the top of the file (deduplicated if the import already exists)
3. Skips moved classes that the file already imports directly
The migration script inserts the import after the 'from __future__
import annotations' line if present; otherwise it adds the import
to the destination module's existing import block. Two files
required manual fixes because the script's regex didn't handle them:
- src/rag_engine.py: uses 'from src import models' (not 'from
src.models import X'); the class is accessed
via 'models.RAGConfig'. Replaced with a
direct 'from src.mcp_client import RAGConfig'
import and removed the 'from src import models'.
- tests/test_project_context_20260627.py: uses the parens-style
multi-line 'from src.models import (X, Y, Z)'.
Replaced with the parens-style direct import.
After this commit:
- 'models.MCPConfiguration', 'models.FileItem', 'models.Ticket', etc.
no longer work in src/ and tests/ (the AttributeError raises
because models.py no longer has the __getattr__ entries for
moved classes)
- All consumer files have direct imports of the moved classes
Total: 44 'models.<moved_class>' references rewritten across 20 files.
Per post_module_taxonomy_de_cruft_20260627 Phase 2 (FR7). Each
'from src.models import X' for a moved class is rewritten to
'from src.<destination> import X':
Ticket, Track, WorkerContext, TrackState, TrackMetadata,
ThinkingSegment, EMPTY_TRACK_STATE -> src.mma
ProjectContext, ProjectMeta, ProjectOutput, ProjectFiles,
ProjectScreenshots, ProjectDiscussion, EMPTY_PROJECT_CONTEXT -> src.project
FileItem, Preset, ContextPreset, ContextFileEntry,
NamedViewPreset -> src.project_files
Tool, ToolPreset -> src.tool_presets
BiasProfile -> src.tool_bias
TextEditorConfig, ExternalEditorConfig,
EMPTY_TEXT_EDITOR_CONFIG -> src.external_editor
Persona -> src.personas
WorkspaceProfile -> src.workspace_manager
MCPServerConfig, MCPConfiguration, VectorStoreConfig,
RAGConfig, load_mcp_config -> src.mcp_client
NOT touched (kept on src.models; Phase 3 or Phase 4 will move them):
GenerateRequest, ConfirmRequest, DEFAULT_TOOL_CATEGORIES, Metadata, PROVIDERS
Migration was performed by the one-time script
scripts/tier2/artifacts/post_module_taxonomy_de_cruft_20260627/migrate_imports.py
which uses a class-to-module map and re.sub() to rewrite each
'from src.models import X' line.
Total: 85 import lines rewritten across 71 files.
Note: this commit depends on the v2 SHIPPED work
(origin/tier2/module_taxonomy_refactor_20260627) being merged into
this branch NEXT. On master (without the v2 SHIPPED commits), the
destination modules do not exist and these imports would fail.
TIER-3 READ AGENTS.md + conductor/workflow.md + conductor/code_styleguides/error_handling.md + the 4 source files + 3 test files before this commit.
The code_path_audit_phase_2_20260624 track (Tier 2) shipped 11 audit
fixes (4 NG1 + 7 NG2) but used a heuristic bypass for 4 of the NG2
wrappers: legacy T | None functions that exist only to maintain test
patcher compatibility. Per the review at
docs/reports/REVIEW_TIER2_code_path_audit_phase_2_20260624.md Finding 8,
this track eliminates the legacy wrappers properly.
11 wrappers eliminated (8 main + 3 _legacy_compat inner):
- src/ai_client.py: get_current_tier (1 src + 1 test consumer)
- src/ai_client.py: _gemini_tool_declaration + _legacy_compat (2 test consumers)
- src/ai_client.py: run_tier4_patch_callback + _legacy_compat (was 0 direct callers
but had 2 callback references in app_controller/multi_agent_conductor;
callback contract migrated to Callable[[str, str], Result[str]] instead of
preserving an Optional[str] adapter)
- src/mcp_client.py: _get_symbol_node + _legacy_compat (8 in-file consumers)
- src/mcp_client.py: find_in_scope (nested inside _get_symbol_node_result;
private impl detail, audit doesn't catch T | None, left as-is)
- src/external_editor.py: launch_diff (1 src + 3 test + 1 live_gui test consumer)
- src/external_editor.py: launch_editor (no consumers; deleted)
- src/session_logger.py: log_tool_output (2 src + 3 test consumers)
- src/project_manager.py: parse_ts (no consumers; deleted)
For each consumer: replace legacy_fn(args) with legacy_fn_result(args).data.
For T | None checks: replace if x is None: with if not result.ok: or
if not result.ok or not isinstance(result.data, ...) (depending on pattern).
For run_tier4_patch_callback specifically: the wrapper was a callback adapter
(not a backward-compat shim) and had 2 callback references as consumers.
Rather than keep the adapter (which would re-introduce the Optional[str]
return that the strict audit catches), the patch_callback contract was migrated
from Callable[[str, str], Optional[str]] to Callable[[str, str], Result[str]]
in shell_runner.py + app_controller.py + 9 _send_<vendor>_result signatures
in ai_client.py. This propagates the Result[str] through the callback and
lets shell_runner unwrap with if r.ok and r.data instead of if patch_text.
Verification:
- audit_optional_in_3_files --strict: 0 return-type Optional[T] (down from 1)
- audit_exception_handling --strict: 0 violations (unchanged)
- audit_legacy_wrappers: 0 legacy wrappers (unchanged)
- 15 affected test files: 168 tests pass
- 8 mcp_client/structural/baseline test files: 55 tests pass
- 3 session/gui test files: 7 tests pass
- 0 return-type Optional[T] in src/ai_client.py (was 1: run_tier4_patch_callback)
project_manager.py (3 sites):
- get_all_tracks returns list[dict[str, Any]] where each dict now
has an 'errors' field (list[ErrorInfo]) capturing per-track
metadata recovery. The 3 SILENT_SWALLOW sites (state.from_dict,
metadata.json, plan.md) now append to this list instead of
silently passing.
orchestrator_pm.py (2 sites):
- get_track_history_summary returns Result[str]. The 2 SILENT_SWALLOW
sites (metadata.json + spec.md reads) append to a scan_errors list
that's threaded through the Result.
Tests updated to check result.ok and use result.data.
A malformed state.toml in conductor/tracks/<track>/state.toml (e.g.,
from an interrupted previous run) caused tomllib.load() to raise
TOMLDecodeError, which propagated up and crashed App.__init__
during init_state() -> _load_active_project() -> _refresh_from_project()
-> get_all_tracks() -> load_track_state().
This manifested as test failures in tests/test_layout_reorganization.py,
tests/test_auto_slices.py, tests/test_hooks.py, and the tier-3-live_gui
batch (all triggered by the same malformed mcp_architecture_refactor_20260606
state.toml).
The fix wraps tomllib.load() in a try/except for (OSError,
tomllib.TOMLDecodeError) and returns None (matching the file-not-found
behavior). This is consistent with the data-oriented convention:
corrupt state is a recoverable failure, not a programmer error.
Tests verified:
- tests/test_track_state_persistence.py (1 test) PASS
- tests/test_layout_reorganization.py (4 tests) PASS
- tests/test_auto_slices.py (3 tests) PASS
- tests/test_hooks.py (3 tests) PASS
The main_context field in Project Settings was stored but never used.
Nothing reads it to inject into AI context. System Prompt in AI Settings
already serves this purpose.
Removed:
- app_controller.py: ui_project_main_context state variable and all refs
- gui_2.py: Main Context File UI section from Projects panel
- project_manager.py: main_context from default_project()
- project.toml, manual_slop.toml, gencpp_manual_slop_template.toml: main_context entries
