+# Pre-Compaction Report - code_path_audit_20260607 v2
+
+**Date:** 2026-06-22
+**Branch:** `tier2/code_path_audit_20260607`
+**Last commit:** `09167986`
+**Status:** v2 SHIPPED with real-data analysis (2136 lines of audit output); SSDL analysis in progress (has indentation bug)
+
+## Current State - TL;DR
+
+The v2 audit tool is **functional and producing real data**. After a mid-session pushback from the user, I rewrote the audit pipeline to:
+1. Stop using hardcoded defaults for access_pattern/frequency/decomposition_cost
+2. AST-walk real `src/` files via 4 new analyzer modules
+3. Generate 2136 lines of audit output (vs the original 1204 lines of empty defaults)
+4. Add SSDL-based analysis (the user's most recent ask)
+
+**Known blocker post-compaction:** `src/code_path_audit_ssdl.py` has an indentation bug that prevents import. The file content is correct in spirit but Python won't parse it. Needs to be rewritten cleanly.
+
+## What's Been Done (commit history)

+### Test files
+- `tests/test_code_path_audit.py` — 96 unit tests for Phase 1-6
+- `tests/test_code_path_audit_phase78.py` — 15 tests for cross-audit + DSL_WORD_ARITY_V2
+- `tests/test_code_path_audit_phase89.py` — 13 tests for DSL renderers + run_audit + CLI + MCP
+- `tests/test_code_path_audit_integration.py` — 7 integration tests against synthetic src/

+
+## What the user wants (post-compaction)
+
+The user's most recent ask: read SSDL docs, then add deductions on codebase organization and restructuring routes. I started this but ran out of context. Post-compaction, the user wants me to:
+
+1. **Fix `src/code_path_audit_ssdl.py` indentation bug** (rewrite the file cleanly)
+2. **Wire SSDL analysis into `run_audit` and `render_rollups`** to add `ssdl_analysis.md` + `organization_deductions.md` rollups
+3. **Generate the full SSDL-enriched audit output** with effective codepaths + nil-sentinel suggestions + organization verdict + restructuring routes
+
+The user's exact words: "Do we have deductions on proper organization of hte codebase and possible routes to restructuring?"
+
+## Critical files to re-read post-compaction
+
+1. **`src/code_path_audit_ssdl.py`** — the broken file (line 34 has the indentation bug; needs full rewrite)
+2. **`docs/guide_ssdl.md`** — SSDL framework (298 lines) — covers the 6 primitives, modifiers, defusing techniques (Nil Sentinel, Generational Handles, Immediate-Mode Cache), combinatoric explosion metric
+3. **`docs/reports/computational_shapes_ssdl_digest_20260608.md`** — SSDL applied to this codebase (390 lines) — covers the 6 primitives, before/after refactor examples, defusing techniques
+4. **`conductor/tracks/code_path_audit_20260607/spec_v2.md`** — the canonical spec (sections 5, 6, 7 cover PCG/MemoryDim/APD/CFE/Cross-audit/DSL/decomposition cost)
+5. **`conductor/tracks/code_path_audit_20260607/plan_v2.md`** — the canonical plan
+6. **`conductor/code_styleguides/data_oriented_design.md`** — the canonical DOD reference (168 lines)
+7. **`conductor/code_styleguides/error_handling.md`** — the Result[T] convention (771 lines)
+8. **`src/code_path_audit.py`** — the main audit tool
+9. **`src/code_path_audit_analysis.py`** — real-data analyzers
+10. **`src/code_path_audit_cross_audit.py`** — finding→aggregate mapping
+11. **`src/code_path_audit_render.py`** — enriched markdown renderer
+12. **`src/code_path_audit_rollups.py`** — rich top-level rollups
+
+## Tasks to do post-compaction (in order)
+
+1. **Fix SSDL file indentation.** The file content is right but Python won't parse it. Just rewrite it cleanly with consistent 1-space indentation. Don't try to fix the existing file; overwrite it.
+
+2. **Wire SSDL into run_audit.** In `src/code_path_audit.py:render_rollups()`, after the existing rollups are written, call:
+   - `from src.code_path_audit_ssdl import render_ssdl_rollup, render_organization_deductions, render_ssdl_sketch`
+   - Write `ssdl_analysis.md` = `render_ssdl_rollup(profiles, "src")`
+   - Write `organization_deductions.md` = `render_organization_deductions(profiles, "src")`
+   - Add to the return dict: `"ssdl_analysis.md": str(...)`, `"organization_deductions.md": str(...)`
+
+3. **Per-profile SSDL sketch.** In `render_full_markdown()` (in `code_path_audit_render.py`), add an SSDL Sketch section that calls `render_ssdl_sketch(profile, "src")`.
+
+4. **Run the full audit again.** `uv run python -c "from src.code_path_audit import run_audit, render_rollups; from pathlib import Path; result = run_audit('src', 'tests/artifacts/audit_inputs', 'docs/reports/code_path_audit', '2026-06-22'); render_rollups(result.data, Path('docs/reports/code_path_audit/2026-06-22'))"`.
+
+5. **Verify tests pass.** `uv run pytest tests/test_code_path_audit.py tests/test_code_path_audit_phase78.py tests/test_code_path_audit_phase89.py tests/test_code_path_audit_integration.py` should still be 131.
+
+6. **Run the 4 audit gates.** `audit_exception_handling.py --strict`, `audit_main_thread_imports.py`, `audit_no_models_config_io.py`, `audit_code_path_audit_coverage.py --strict` (excluding the 2 known regressions).
+
+7. **Commit.** `git add src/code_path_audit.py src/code_path_audit_render.py src/code_path_audit_ssdl.py docs/reports/code_path_audit/2026-06-22/` then `git commit -m "feat(audit): SSDL analysis - effective codepaths + nil-sentinel suggestions + organization verdict"`.
+
+8. **Update TRACK_COMPLETION report** at `docs/reports/TRACK_COMPLETION_code_path_audit_20260622.md` to include the SSDL section.
+
+9. **Write a clear summary** to the user explaining: "Yes, here's the actual deduction. The audit identified these aggregates need restructuring via these specific defusing techniques."
+
+## Real-data analysis (what the audit actually computes now)
+
+After all the post-merge + post-pushback work:
+
+- **PCG:** AST walks src/, finds producers via `-> T` and `-> Result[T]` return annotations; consumers via `: T` parameter annotations. **77 Metadata producers, 35 Metadata consumers** (real function names).
+- **APD:** For each consumer function, AST walks the body, counts `entry['key']` / `entry.attr` accesses on each parameter, builds per-function pattern. Aggregate-level pattern = dominant (>=25% share).
+- **CFE:** Entry-point heuristic (caller name → frequency bucket). All current consumers classified as "per_turn" (heuristic — not yet call-chain analysis).
+- **Decomposition Cost:** per_call_cost from struct_field_count (50µs per field + 100µs per hot field + 20µs frozen bonus), scaled by frequency multiplier. Real numbers like 470µs current cost for Metadata.
+- **Cross-audit mapping:** Function lookup (find_enclosing_function with line=0 fallback to file-level) → file→aggregate index → unbucketed. Handles both `file` and `filename` JSON keys. Path normalization for Windows paths.
+- **Field access:** Detected 130 field-access sites across 35 Metadata consumers. **Example real data:** `app_controller._on_comms_entry` accesses `local_ts`, `_offload_entry_payload`, `get`, `ui_auto_add_history`, `_pending_comms_lock`, `session_usage`, `_pending_history_adds_lock`, `_token_history`, `_pending_comms`, `_pending_history_adds` (10 fields, 28 total accesses).
+- **Optimization candidates:** Auto-generated for non-"hold" directions. Currently 0 because most aggregates are frozen + whole_struct (which is "ideal").
+
+## Known regressions (NOT from this track)
+
+- `audit_weak_types.py --strict`: 117 vs 112 baseline (regression of 5) — from cherry-picked commits (openai_schemas, mcp_tool_specs, provider_state, log_registry)
+- `audit_optional_in_3_files.py --strict`: 7 pre-existing `Optional[T]` violations in mcp_client + ai_client
+
+## Spec coverage
+
+The spec calls for these layers (all implemented; quality varies):
+
+| Spec section | Implementation | Quality |
+|---|---|---|
+| Per-aggregate profile structure | `AggregateProfile` dataclass + `synthesize_aggregate_profile` | ✅ Real data |
+| PCG with 3 AST passes | `P1_pass`, `P2_pass`, `P3_pass`, `build_pcg` | ✅ Real producer/consumer lists |
+| MemoryDim classifier | `classify_memory_dim` with overrides > canonical > file heuristic > unknown | ✅ Uses real canonical mappings |
+| APD with 5 patterns | `detect_access_pattern` | ✅ Per-consumer evidence (130+ sites) |
+| CFE with 7 frequencies | `estimate_call_frequency` with entry-point heuristic | ⚠️ All classify as "per_turn"; no call-chain analysis |
+| Decomposition Cost | `compute_decomposition_cost` | ✅ Real numbers (470µs current, 70µs savings) |
+| Cross-audit integration | 6 input JSONs + 3-tier mapping | ✅ File-level bucketing works |
+| v2 DSL (14 tagged words) | `DSL_WORD_ARITY_V2`, `to_dsl_v2`, `parse_dsl_v2` | ✅ Flat-section format |
+| run_audit + CLI + MCP | `run_audit`, `argparse` CLI, `code_path_audit_v2` MCP wrapper | ✅ |
+| 13 per-aggregate files | All 13 (10 real + 3 candidate placeholders) | ✅ |
+| 4 top-level rollups | summary, cross_audit_summary, decomposition_matrix, candidates (+ 4 more: field_usage, call_graph, hot_paths, dead_fields) | ✅ |
+| SSDL analysis | `code_path_audit_ssdl.py` (broken — needs fix) | ❌ Broken |
+| Organization deductions | `render_organization_deductions` (broken) | ❌ Broken |

+
+## Final note for post-compaction agent
+
+The user's pushback mid-session ("your at 91% context. Where is the full report?") revealed the audit output was structurally empty (all hardcoded defaults). I rewrote the analysis pipeline to AST-walk real `src/` files. The user then asked for SSDL-based deductions, which I started implementing but ran out of context on the indentation.
+
+**The most important thing to remember post-compaction:** The user wants DEDUCTIONS, not data dumps. After fixing SSDL, write the final response in a way that says "here's what the audit tells us about the codebase organization, here's where the restructuring routes are." The current TRACK_COMPLETION is too passive ("here's what we shipped") — the post-compaction work should produce active deductions.
