The SSDL digest (docs/reports/computational_shapes_ssdl_digest_20260608.md,
504 lines, 30KB) is the theoretical foundation for the chunkification
pattern. Per the digest's Technique 5 "Assume-away (Xar)" in §2.2
and the "Xar-style chunked arrays" recommendation in §5.2, the
chunkification track is a *direct application* of the SSDL's
"assume as much as possible" lens (§4).
This commit adds the SSDL digest to the See Also of the v1+v2
C11-Python interop assessment (front-matter Cross-references line).
The same cross-reference is also being added to:
- conductor/tracks/chunkification_optimization_20260608_PLACEHOLDER/spec.md
(in a new §6.1 "SSDL alignment" subsection)
- conductor/tracks/manual_ux_validation_20260608_PLACEHOLDER/spec.md
(in §5 Architectural Reference + §6 See Also + a new §2.6
"SSDL cross-reference" section that distinguishes GUI ASCII
vocabulary from SSDL vocabulary)
No code modified. Cross-reference only.
Also: small update to conductor/tracks.md to add the 2 new
tracks (manual_ux_validation_20260608_PLACEHOLDER as Active;
chunkification_optimization_20260608_PLACEHOLDER as Backlog/Contingency).
The user specified that the code_path_audit_20260607 track should run
AFTER the 4 foundational tracks complete (qwen_llama_grok,
data_oriented_error_handling, data_structure_strengthening,
mcp_architecture_refactor). This commit formalizes that timing
and grounds the audit's analytical framing in the 5 sources loaded
into context on 2026-06-08.
3 surgical additions to the spec/plan, no task changes:
1. Post-4-tracks timing (new section in spec.md §"Timing", plus
a "Timing" callout in plan.md's opening):
- The 4 tracks will significantly reshape src/ai_client.py,
src/mcp_client.py, src/app_controller.py, and
src/type_aliases.py
- Running the audit on pre-refactor code would produce a
report that's stale on day 1
- The post-4-tracks timing ensures the audit grounds
optimization decisions for the *resulting* architecture
- Pre-flight check: verify all 4 tracks are [x] completed
in conductor/tracks.md before starting this track
2. Analytical framing (new section in spec.md §"Analytical Framing
(5-source lens)"):
- Maps each of the 5 sources (Fleury taxonomy + Fleury
combinatoric + Muratori Big OOPs + Reece Assuming + user's
chunk ideation) to specific audit-time heuristics
- 4 concrete heuristics: effective-codepath count,
entity-hierarchy fingerprint, assumed-too-much detector,
chunkification candidates
- The heuristics shape REPORT INTERPRETATION, not the
static cost model (which stays data-grounded in
EXPENSIVE_THRESHOLD + per-class weights)
3. See Also cross-references in spec.md (6 new entries):
- nagent_review Pitfalls #2 and #4 (provider history
globals + stateful singleton)
- wo84LFzx5nI Big OOPs transcript (full text, 4310
segments, 200KB; loaded 2026-06-08)
- i-h95QIGchY Assuming transcript (full text, 3719
segments, 162KB; loaded 2026-06-08)
- ed_chunk_data_structures_20260523.md (5-image archive
of user's chunk ideation, 19KB; saved 2026-06-08)
- computational_shapes_ssdl_digest_20260608.md (the SSDL
digest that synthesizes the 4-source computational-shapes
thinking; the audit's tree/mermaid outputs ARE
computational-shape visualizations)
4. tracks.md entry updated to include the spec/plan links and
a brief status note that the audit is post-4-tracks.
5. plan.md has a "Timing" callout at the top stating the 4
tracks must ship before the plan executes.
No code modified. The audit's tasks (Phases 1-6) are unchanged
in structure; the new sections only add analytical context
and timing constraints.
Phase 4 verification complete: 4 atomic commits landed, 28
unit + integration tests passing, the audit script runs
end-to-end against the post-cleanup repo, --strict mode
+ baseline file wired in as the CI gate. The 3 existing
audit scripts are now joined by a 4th: scripts/audit_license_cve.py.
Scope: third-party deps only. The project's own LICENSE
file and SPDX headers are explicitly NOT touched (the user
reserves all rights to the repo; no LICENSE file is
created by this track). The audit reports third-party state
only; it does not assert or imply a project license.
Commits:
a8ae11d3 - chore(audit): add license_cve audit script + initial report
20fa3558 - chore(deps): tilde-pin all deps; delete requirements.txt
a7ab994f - chore(audit): add --strict mode + baseline file (CI gate)
(this) - conductor(tracks): mark track complete
All 6 sub-tracks (2A-2F) complete. Audit script: 0 violations (was 67 baseline / 61 before sub-track 2). Track is now FULLY COMPLETE (was previously [~] due to sub-track 2 partial). 79 tests added/passing across sub-tracks 2A-2F. Updated sub_tracks table in state.toml with per-sub-track completion details. Pre-existing test failures (4 unrelated) documented in test_failure_notes.
Phase 9 was shipped at 12cec6ae and the 9-phase core plan is done, but the [COMPLETE 2026-06-07] tag was applied prematurely. Sub-track 2 (audit violations) remains partial at ae3b433e with 61 violations remaining: pydantic in models.py (1), tree_sitter in file_cache.py (4), api_hooks.py (4), sloppy.py (5), app_controller.py (23), gui_2.py (24). Reopening the track to finish sub-track 2 in 6 per-file sub-tracks (2A-2F).
Track + metadata + state + tracks.md registration for the 2,205-line
mcp_client.py split into a slim controller + 6 native sub-MCPs + 1
external sub-MCP.
Key design decisions (per user feedback):
- Naming convention: mcp_<type>.py for native MCPs (mcp_file_io.py,
mcp_python.py, mcp_c.py, mcp_cpp.py, mcp_web.py, mcp_analysis.py).
- ExternalMCPManager class name preserved (moves to mcp_external.py).
- Sub-MCP shape: class with name / description / tools / invoke().
- MCPController: holds ALL_SUB_MCPS list, inverted-dict tool lookup,
3-layer security (extracted to mcp_client_security.py), schema
aggregation.
- Each invoke() returns Result[str, ErrorInfo] (from
data_oriented_error_handling_20260606).
- Backward compat: mcp_client_legacy.py re-exports all 45+ old
symbols; the 4 existing test files + src/app_controller.py:61
direct call continue to work.
DSL future (per user notes on APL/K/Cosy): NOT in this track.
Documented in spec §12.1 as the mcp_dsl_20260606 follow-up.
Sub-MCP architecture is the natural unit to pair with a DSL emitter.
7 phases. ~22 task slots. New tests: 9 (one per sub-MCP + controller +
security + legacy). Modified tests: 4 (existing mcp_* tests must
pass unchanged).
Blocked by: data_oriented_error_handling_20260606, data_structure_strengthening_20260606.
Blocks: mcp_dsl_20260606 (future DSL track).
Track + metadata + state + tracks.md registration for the type-aliases
refactor that follows the audit_weak_types.py findings (430 weak sites
across 29 of 61 files; 86% concentrated in 6 high-traffic files).
Key design decisions (per user approval):
- 10 TypeAlias definitions in src/type_aliases.py (Metadata, CommsLogEntry,
CommsLog, HistoryMessage, History, FileItem, FileItems, ToolDefinition,
ToolCall, CommsLogCallback).
- 1 NamedTuple (FileItemsDiff) for the _reread_file_items return.
- Mechanical replacement of 345 weak sites across 6 files (NOT 430; the
remaining 85 are in 23 lower-impact files deferred to future tracks).
- scripts/audit_weak_types.py gains a --strict mode and a baseline file
(scripts/audit_weak_types.baseline.json) so the count is enforced.
- 2 phases: aliases + 6-file replacement + audit baseline; NamedTuples
+ docs + archive.
- Honest about what's missing: TypedDict / @dataclass migration is a
follow-up track (typed_dict_migration_20260606), not this one.
- Coexistence with the data_oriented_error_handling_20260606 track's
Result[T] / ErrorInfo: the aliases are value-level (data types), Result
is control-level (wrapper). They compose (Result[FileItems] is valid).
No conflict.
Audit baseline:
- Pre-track: 430 weak sites, 0 strong patterns
- Target after Phase 1: ~60 weak sites (only the 23 lower-impact files)
- Top 4 unique type strings account for 86% of findings (4-6 aliases
eliminate the bulk of the noise).
Not blocked by anything; can be executed independently of the other
pending tracks. Blocks typed_dict_migration_20260606 (the future Phase 2).
Track + metadata + state + tracks.md registration for the Fleury-pattern
error handling refactor.
Key design decisions (per user approval):
- Option A for _send_<vendor>() handling: rename to _send_<vendor>_result()
and change return type to Result[str] (contained to internal callers).
- send() is marked @typing_extensions.deprecated; send_result() is the new
public API.
- ProviderError exception is FULLY REPLACED by ErrorInfo dataclass
(a value, not an exception).
- 5 phases: foundation, mcp_client, ai_client, rag_engine, deprecation+archive.
- Post-tracks baseline check (Phase 1 Task 1.1) verifies the 3 pending
tracks have merged before proceeding.
- 9 Open Questions, 7 Risks, 5 verification criteria, follow-up track
public_api_migration_20260606 planned in spec §12.1.
Blocked by: startup_speedup_20260606, test_batching_refactor_20260606,
qwen_llama_grok_integration_20260606. Blocks: public_api_migration_20260606.
Fulfills the existing backlog entry at conductor/tracks.md:152
(2026-06-05 root-cause analysis of live_gui wait_for_server timeouts).
Main Thread Purity Invariant: the main thread (entering immapp.run())
must never import a module heavier than imgui_bundle and the lean
gui_2 skeleton. Enforced by:
- static gate: scripts/audit_main_thread_imports.py (CI)
- runtime hook: tests/test_main_thread_purity.py (sys.addaudithook)
Threading constraint: no new threading.Thread(...) calls in src/.
All background work goes through AppController._io_pool
(ThreadPoolExecutor, max_workers=4, thread_name_prefix='controller-io').
9 phases, 57 tasks: audit+baseline, job pool, lazy-load SDKs, lazy-load
FastAPI, lazy-load feature-gated GUI, migrate ad-hoc threads, runtime
enforcement, hook API + diagnostics, verify+checkpoint.
Expected savings: ~2000-2400ms off main-thread import cost.
Target: import src.ai_client < 50ms (from ~1800ms), live_gui fixtures
no longer time out at wait_for_server(timeout=15).
Previously, context (files, screenshots) was always sent with every message,
even on subsequent messages where the AI provider already had the context
from the first message via its history mechanism.
This change:
- Detects if the discussion has any AI responses already
- Only sends md_content (stable_md) on the first message
- Subsequent messages pass empty string for md_content to avoid redundant sending
- Context now properly goes in md_content parameter, not crammed into user_message
The fix is in _api_generate() in src/app_controller.py
- Restore monolithic architecture in gui_2.py to fix test breakages and circular imports.
- Update Text Viewer stable ID to '###Text_Viewer_Unified' to definitively fix docking conflicts.
- Refactor discussion entry renderer to force full-width horizontal expansion for Markdown.
- Fully restore theme_2.py definitions (palettes, fonts, scale) while retaining role-tint logic.
- Robustify ImGui ID stack in imgui_scopes.py to prevent access violations.
- Verify all fixes with the comprehensive unit and visual test suite.
- Resolve ImportError by correctly prefixing 'src' in modular renderers.
- Fix ImGui access violation by ensuring push_id always receives string IDs.
- Restore visible role-based background tints using layered rendering (channels).
- Definitively fix horizontal Markdown table widths by forcing group expansion.
- Centralize color management in theme_2.py and ui_shared.py.
- Standardize Files & Media inventory layout and remove legacy controls.
- Update test mocks to support modular UI and theme-driven styling.
- Update test_gui_symbol_navigation.py and test_gui_text_viewer.py to assert against show_windows['Text Viewer'] instead of the deprecated show_text_viewer attribute.
- Increase synchronization wait time in test_visual_sim_gui_ux.py to ensure the GUI loop accurately reflects the mocked MMA status.
- Display token metrics (input/output/cache) per response in Discussion Hub.
- Add total Discussion Token usage in the panel header.
- Implement 'Compress' feature to intelligently summarize and replace exhausted discussion histories using an AI subagent.
