Krzysztof kuhy Rudnicki 7cb23e8a81 Prettier-normalize two docs the pre-push hook was already failing on
Both were non-conforming before this session and block every push, not
just this one, since the hook runs over all files. The diff is entirely
table-separator widths and emphasis markers; no prose changes.

# Refactor TODO — enforce the 250-line file cap
> **This file is a ready-to-use prompt.** Paste it to Claude, or open this repo
> and say "do refactor_claude_todo". It is self-contained: everything needed to
> execute is below. Generated 2026-08-14 from a measured survey of every repo.
## Goal
Every file in this repo must be **at most 250 lines** — source, tests, and
prose (`.md`/`.txt`/`.rst`/`.tex`) alike — and must **stay** that way forever,
enforced by a gate that fails the commit, not by a note anyone can ignore.
Why: a file that cannot be read in one piece forces re-reads and partial edits,
which is the single largest avoidable cost in an LLM-assisted workflow. Aim by
churn, not size alone — refactoring pays where code is read and changed often
(Fowler, _refactoring economic benefit_).
## Scope in this repo
- **197 files** currently exceed 250 lines (of 801 eligible files).
- **87,393 lines** sit in violation; longest file is **2053 lines**.
Exempt (do NOT split these):
- generated files — `*.g.dart`, `*.freezed.dart`, `*.gr.dart`, `**/l10n/generated/**`,
anything with a `GENERATED` header
- markup — `.html`, `.css`, `.scss`
- data files — `.json`, `.yaml`, `.csv`, wordlists and other data-ish `.txt`
(mean line length under 25 chars)
## Violations, highest ROI first
ROI = lines x commits in the last year. Work top-down; a long file nobody edits
has near-zero payoff and should not be first.

## How to split
- **Python** — extract cohesive helpers into sibling modules; keep the public
API and imports stable.
- **Shell** — split into `lib/*.sh` sourced by a thin entry script. Keep
`set -euo pipefail` in each.
- **Dart / TypeScript** — extract widgets/components into their own files.
- **Tests** — split by test-group into sibling files
(`foo.test.ts` -> `foo.parsing.test.ts`, `foo.render.test.ts`). Coverage must
not drop.
- **Docs** — split into topic files under `docs/` with an index. For an
oversized `CLAUDE.md`, move detail into referenced docs so the
always-loaded part shrinks.
**Do not** game the cap: no one-lining, no deleting tests, no moving code into
an exempt extension, no `# noqa`-style suppressions.
## Make it permanent (required — this is the point)
A refactor without a gate silently regrows. Before this task is done:
1. Wire the shared gate `~/utils/scripts/check_file_length.sh` into this repo's
`.pre-commit-config.yaml` as a local hook. If the repo has no pre-commit
config, add a minimal one.
2. The hook checks **files in the commit** (not the whole tree), so unrelated
commits never break, and it **fails** — exit 1, not a warning.
3. No baseline file and no allowlist. Those are suppressions.
4. If this repo has CI (`.github/workflows`), add the same check there so it
also fails on push.
## Done condition
- `bash ~/utils/scripts/check_file_length.sh --all` from this repo root exits 0.
- The repo's own test suite and coverage bar are still green.
- `pre-commit run --files <changed files>` passes.
- A deliberately over-250-line test file, staged, makes `git commit` **fail**.
- For a deployed daemon/app: the entry point still actually runs.
## Verify
Many scripts here run from systemd timers and the working tree. After splitting a script, run it directly and confirm the timer unit still resolves its path.
