The comment rule in CLAUDE.md is one line maximum, never narration: no multi-line blocks, no module-header explainers, no sentences that explain or justify the code to the reader. The tree had drifted a long way from it, and most of the drift is mine. Removed: 232 lines of multi-line comment blocks 203 single-line comments that argued instead of stating 154 comments joined by so/because/otherwise/rather-than 143 narrating comments in the frontend 112 test docstrings (the test name already says what it asserts) 25 test module docstrings and 25 decorative section dividers Collapsed: 324 multi-line docstrings to one factual line 271 one-line docstrings that had a justifying clause bolted on Kept: functional directives, section dividers, short field labels, alembic revision headers, and the eight FastAPI route docstrings that render in /docs. Where a fact was load-bearing it is in CLAUDE.md, which is where it belongs. 284 python tests and 34 frontend tests pass, ruff and ruff-format clean across ten packages, svelte-check 0 errors, prettier and eslint clean, app.main imports.
