Repo Hygiene: Step Order + Split Report

Summary

Repository maintenance task focused on restoring consistency to the documentation system. Reorganized the split report (`docs/report_phase_2/`) to comply with the declared ranges of Steps, removed duplicate/obsolete files, and resolved outstanding stashes containing obsolete code. This Step is exclusively for documentation (docs-only), without changes to the source code.

Identified problem:The file `parte_00_steps_0370_0412.md` indicated in its name a range up to Step 0412, but contained Steps up to 0417. The index (`index.md`) declared "370-416" but the actual file had up to 0417. Additionally, there were 4 duplicate versions of the same file (0378, 0379, 0401, 0412) without cleaning.

Applied solution:Creation of new part (`part_01_steps_0412_0450.md`) for Steps 0412+, correction of part 00 to contain only Steps 0370-0411, renumbering of all subsequent parts, removal of duplicates, and discarding stashes with obsolete code. ✅ Successful build. ✅ CPU tests passing (6/6). ⚠️ ALU tests failing (10/27 - pre-existing).

Concept: Documentation Management in Large Projects

On long-term projects with hundreds of development Steps, keeping documentation organized is critical to team productivity and project history clarity.

Applied principles:

• Split Report: Documentation files with size limit (~2000 lines) for ease of reading by humans and AI agents
• Explicit Ranges: File names clearly indicate the range of content (e.g. `part_01_steps_0412_0450.md`)
• Central Index: `index.md` file that lists all parts with their updated ranges
• No Duplication: A Step must appear in exactly one part of the report
• Chronological order: Most recent steps first within each part

Stashes Management:

Git stashes are useful for temporary work, but they can add up and create confusion. In this Step the following strategy was applied:

• Classification: Type A (docs-only) vs Type B (code included)
• Analysis: Compare contents of stash with current HEAD using `git diff stash@{N}`
• Decision: Apply (if relevant docs-only), Park in WIP branch (if non-merged code), or Discard (if deprecated/reverted code)
• Documentation: Record the decision made for each stash

Implementation

T1: Audit

Checked the current state of the repository:

• HEAD: `7da1360` on branch `develop-v0.0.2` (clean, synced)
• Working tree: Clean (untracked plan file only)
• Stashes: 2 identified (both Type B with code)
• Split report: File `parte_00_steps_0370_0412.md` with 5365 lines containing Steps up to 0417
• Duplicates: 4 obsolete versions (0378, 0379, 0401, 0412)

T2: Split Report Reorganization

Steps executed:

1. Extracting Steps 0412-0417 from original file using `git show` and line commands
2. Creating `parte_01_steps_0412_0450.md` (535 lines, 6 Steps: 0412-0417)
3. Correction of `parte_00_steps_0370_0411.md` (4863 lines, 42 Steps: 0370-0411)
4. Renumbering of subsequent parts: 01→02, 02→03, 03→04, 04→05, 05→06, 06→07
5. Removing duplicate files using `rm -f`
6. Update `index.md` with correct ranges

T3: Stashes Resolution

Both stashes were classified as Type B (code) and analyzed:

• stash@{0}: "WIP before STEP0417A diag" - Contained changes from Step 0416 in `PPU.cpp` (reverted code) →DISCARDED
• stash@{1}: "WIP preflight baseline" - Contained changes from Step 0415 in `MMU.cpp`, `PPU.cpp`, `renderer.py` (reverted code) →DISCARDED

Decision: Both stashes contained obsolete Steps code that were marked as [REVERSED] in the report. They were dropped using `git stash drop`.

T4: Verification

Commands executed with output redirected to `/tmp`:

python3 setup.py build_ext --inplace > /tmp/viboy_step0418_build.log 2>&1
python3 test_build.py > /tmp/viboy_step0418_test_build.log 2>&1
pytest -q > /tmp/viboy_step0418_pytest.log 2>&1
pytest -q tests/test_core_cpu.py > /tmp/viboy_step0418_pytest_cpu.log 2>&1

Results (exit codes):

• BUILD:EXIT 0(build successful)
• TEST_BUILD:EXIT 0(checkpoint OK)
• PYTEST:EXIT 1(10 failed, 17 passed - pre-existing ALU tests)
• PYTEST_CPU:EXIT 0(6/6 passed)

Next Steps

• Step 0419: Continue PPU/Zelda-DX investigation (white framebuffer issue identified in Step 0416)
• Keep the split reporting system up to date as new Steps are added
• Create new part when `part_01_steps_0412_0450.md` exceeds 2000 lines
• Resolve failing ALU tests (10/27 - pre-existing issue, not caused by this Step)
