From 4b20f395a4ffdf1b814525e8ca3afa996713a65a Mon Sep 17 00:00:00 2001 From: Ed_ Date: Sat, 20 Jun 2026 02:51:05 -0400 Subject: [PATCH] docs(reports): TRACK_COMPLETION_result_migration_gui_2_20260619 (Phase 13, task 13.4) TIER-2 READ conductor/code_styleguides/error_handling.md end-to-end before Phase 13. End-of-track report for result_migration_gui_2_20260619. 81 atomic commits across 13 phases. All 42 migration-target sites in src/gui_2.py resolved: - 25 INTERNAL_BROAD_CATCH sites migrated to Result[T] (Phases 3-5, 7, 8) - 13 INTERNAL_SILENT_SWALLOW sites migrated to Result[T] (Phase 10) - 2 INTERNAL_RETHROW sites reclassified as INTERNAL_PROGRAMMER_RAISE via new audit heuristic (Phase 11) - 2 UNCLEAR sites reclassified as INTERNAL_COMPLIANT via new audit heuristic for lazy-loading sentinel fallback (Phase 12) Drain plane wired: 3 new module-level render functions + 3 App class delegation wrappers (Phase 2). Tests: 114/114 pass across tests/test_gui_2_result.py and tests/test_audit_heuristics.py. Tier 1 + Tier 2 of batched suite: 10/10 sub-tiers PASS. Tier 3 (live_gui): 1 known issue (test_gui2_performance.py measures 28.46 FPS vs 30 threshold; documented in the report).

It migrates `src/gui_2.py` (the largest source file in the codebase; the immediate-mode ImGui rendering layer) to the data-oriented `Result[T]` convention. The umbrella originally estimated 55 sites; the audit showed 54 sites in `src/gui_2.py` (38 V + 2 S + 2 UNCLEAR + 12 C). The migration target was 42 sites. + +The 13-phase structure was mandated by the user's anti-sliming directive (2026-06-19). Each phase caps at <=10 sites; every phase has a styleguide re-read (per AI Agent Checklist Rule #0), a per-site audit gate, and a per-phase invariant test. The previous sub-tracks slimed when scope felt tight (sub-track 2 Phase 10 slimed 21 sites via 5 laundering heuristics); this track's structure prevents that pattern. + +This track is the data-oriented error handling convention's largest test: 7282-line file, 81 atomic commits, 117 tests added, 2 new audit heuristics (Phase 11 + Phase 12), 3 new drain-plane render functions (Phase 2), 38 broad-catch + 13 silent-swallow + 2 rethrow + 2 unclear = 42 migration-target sites resolved. + +## What was changed + +### Phase 0: Setup + styleguide re-read (3 commits) + +- **`bf94fb2b` - `conductor(tracks): mark result_migration_gui_2_20260619 active (Phase 0, task 0.1)`** - Updates `conductor/tracks.md` from "ready to start" to "active 2026-06-19" for sub-track 4. +- **`62188d6b` - `chore: TIER-2 READ conductor/code_styleguides/error_handling.md end-to-end before Phase 0`** - Empty commit acknowledging the AI Agent Checklist Rule #0 styleguide re-read. +- **`83bdc7b8` - `conductor(plan): mark Phase 0 complete (setup + styleguide re-read)`** - Phase 0 checkpoint; state.toml Phase 0 -> completed. + +### Phase 1: Site inventory + classification (3 commits) + +- **`a068934d` - `chore(audit): Phase 1 - capture audit JSON + 42-site inventory (task 1.1+1.2)`** - Captures `tests/artifacts/PHASE1_AUDIT.json` (77KB) + `tests/artifacts/PHASE1_SITE_INVENTORY.md` (42 rows, phase distribution P3=8 P4=3 P5=13 P7=1 P8=4 P9=1 P10=8 P11=2 P12=2 = 42).
