Adopt the four markdown namespaces and gate them

Renames this repo's markdown onto README.md / CLAUDE*.md / DOCS*.md /
TODO*.md so a future session can tell a live task from a finished
record without reading the file to find out.

TODO files carry the literal "REMOVE ME AFTER FINISH" and are deleted
when the work lands. Enforced by the md-naming pre-commit hook and CI
workflow, both delegating to the shared gate in kuhyx/utils so this
repo's idea of a valid name cannot drift from every other repo's.

-### Violations
-
-- **Rule 1 (near-black/near-white)** — `web/src/index.css:9` — `--heading: #ffffff` is pure white while every other neutral (`--bg:#0f1117`, `--panel:#161922`, `--border:#2a2f3a`) is deliberately muted → give `--heading` a near-white value with the same cool tint, e.g. `#eef2f6`.
-- **Rule 2 (saturate neutrals)** — `web/src/index.css:9` — `--heading:#ffffff` has zero saturation, breaking the otherwise-consistent cool-tinted neutral family (`--bg`, `--panel`, `--panel-2`, `--card`, `--border`, `--muted` all carry a slight blue hue) → tint it to match (see Rule 1 fix).
-- **Rule 4 (everything deliberate)** — `web/src/index.css:203` and `:489` — `.seg.active { color: #06121c }` and `.badge { color: #1a1205 }` are one-off hardcoded "ink" colors with no token, unrelated to any other value in the file → promote to `--on-accent`/`--on-warn` custom properties so the choice is traceable and reusable.
-- **Rule 6 (letter-spacing/line-height by size)** — `web/src/index.css:37-44` — only `h1` (26px) gets a letter-spacing adjustment (`-0.4px`, line 39); none of the 13 smaller sizes in the file (10px badge line 487, 11px axis-label line 404, 12px `.seg`/`.ghost` lines 199/214, 13px `.hint`/table/`.field label` lines 83/127/440) get any compensating letter-spacing or line-height increase → add a small positive letter-spacing (~0.1-0.2px) to the ≤13px tier.
-- **Rule 9 (distinct brightness values)** — `web/src/index.css:10,12` — using the HSB-brightness metric the rule's thresholds are defined in (max(R,G,B)/255, matching Rule 18), `--accent` (#66c0f4) is 95.7% and `--warn` (#f0a23b) is 94.1% — only 1.6 points apart; `--accent-2` (81.2%) and `--danger` (89.0%) are well clear of both, so this is narrowly an accent-vs-warn issue, not a whole-palette one → nudge `--warn` a few points darker (e.g. `#e8952e`, ≈89% brightness) so it doesn't sit this close to `--accent`. Low priority: the two colors aren't used adjacently in the current UI (accent = numeric totals, warn = the "slower than leisure" insight label and the "no data" badge).
-- **Rule 11 (mathematically related measurements)** — `web/src/index.css` throughout — spacing/radius values are 24, 20, 18, 14, 12, 10, 9, 8, 7, 6, 5, 4, 2, 1px (e.g. panel padding 18px line 111, card padding 14px line 275, th padding 9px line 448, td padding 7px line 462, ghost padding 5px line 210) with no shared base unit; radii alone use four unrelated hardcoded values (4px line 56, 6px lines 168/196/211, 8px lines 188/256/274/321/435, plus the `--radius:10px` token line 14) → consolidate onto one scale (e.g. 4px base: 4/8/12/16/20/24) and derive radii from `--radius` and `--radius-sm`.
-- **Rule 13 (12-column grid)** — `web/src/index.css:90` and `:263` — `.layout` uses a fixed `320px 1fr` split and `.cards` uses `repeat(4, 1fr)` / `repeat(2, 1fr)` (line 268), neither derived from a shared 12-column track → define one grid scale (e.g. a `--grid-12` template) both layouts pull from, for future 1/2/3/4-up flexibility.
-- **Rule 20 (body text ≥16px)** — `web/src/index.css:28` — `body { font: 15px/1.5 var(--sans); }` is below the 16px floor, and most UI text sits well under that: `.hint`/`.field label`/table/`.parity` at 13px (lines 83, 127, 247, 440), `.seg`/`.ghost`/`.card-blurb` at 12px (lines 199, 214, 286), `.preset`/`.axis-label` at 11px (lines 310, 404), `.badge` at 10px (line 487) → raise body copy to 16px minimum; for the dense data-table cells where 13px is a deliberate density trade-off, note that explicitly rather than leaving it as the default scale.
-- **Rule 22 (button padding: horizontal = 2× vertical)** — `web/src/index.css:195` — `.seg { padding: 6px 4px; }` has horizontal padding *less* than vertical (should be ~2× more, e.g. `6px 12px`) → `.ghost` at `web/src/index.css:210` (`padding: 5px 10px`) already gets this right and can be the reference.
-- **Rule 24 (nest corners properly)** — `web/src/index.css:188-196` — `.segmented { border-radius: 8px; padding: 4px; }` containing `.seg { border-radius: 6px; }`; per the rule the nested radius should be outer − gap = 8 − 4 = 4px, not 6px → change `.seg` to `border-radius: 4px`.
-- **Rule 26 (no shadows in dark interfaces)** — `web/src/index.css:17` declares `color-scheme: dark` (bg `#0f1117`); `web/src/index.css:279` — `.card.active { box-shadow: 0 0 0 1px var(--accent); }` is technically a shadow in a dark UI → replace with a non-shadow selection indicator, e.g. `outline: 1px solid var(--accent)` or a border-color swap, which reads identically without invoking box-shadow. (Low severity: this is a 0-blur selection ring, not an elevation shadow, but it's the literal case the rule flags.)
-
-### Not applicable
-
-- Rule 5 (optical alignment) — no icons or asymmetric shapes in the codebase whose bounding-box center would differ from its visual center.
-- Rule 8 (everything aligns with something else) — no misalignment identifiable from CSS/JSX alone; needs a rendered pass to verify.
-- Rule 12 (order by visual weight) — layout-level judgment call (sidebar vs. content ordering); no clear violation visible in source.
-- Rule 14 (space between high-contrast points) — requires visual inspection of rendered edges, not determinable from source.
-- Rule 16 (drop shadow blur ≈ 2× distance) — the only `box-shadow` in the file (line 279) has 0 offset/0 blur, so the ratio rule doesn't meaningfully apply.
-- Rule 21 (line length ~70 chars) — no long-form paragraph content; all text is short UI labels/hints.
-- Rule 28 (lower icon contrast paired with text) — no dedicated icon glyphs; the only icon-like characters are the sort arrows (`▲`/`▼` in `web/src/components/GameTable.tsx:115`), which inherit the same color as the adjacent header text rather than being a separate heavier element.
-
-### Passing
-
-- Rule 3 (high contrast for important elements) — `.seg.active` (`web/src/index.css:202-204`) pairs `background: var(--accent)` with `color: #06121c`, a very high-contrast combination for the primary interactive state.
-- Rule 7 (border contrast with both surfaces) — in HSB brightness, `--border:#2a2f3a` (22.7%) sits clearly above `--bg` (9%) and `--panel` (13.3%) wherever it's used as a divider. Caveat: against `--card:#1b2838` (22.0%) the gap is only 0.7 points — e.g. `.card { border: 1px solid var(--border) }` at `web/src/index.css:273` — border is technically still lighter but not "clearly" so; if card borders read as blurry in practice, lighten `--border` or darken `--card` by a few points.
-- Rule 10 (warm OR cool neutrals) — all neutrals (`--bg`, `--panel`, `--panel-2`, `--card`, `--border`, `--muted`) carry a consistent cool/blue tint.
-- Rule 15 (closer elements lighter) — HSB brightness (max(R,G,B)/255) increases monotonically through the stack: `--bg`(9.0%) < `--panel`(13.3%) < `--panel-2`(18.8%) < `--card`(22.0%) < `--border`(22.7%) < `--muted`(63.1%) < `--text`(87.5%) < `--heading`(100%).
-- Rule 17 (simple on complex / complex on simple) — every surface in `index.css` is a single flat color; no competing textures or gradients anywhere.
-- Rule 18 (container brightness limits) — HSB brightness deltas between stacked containers (`--bg`9.0%→`--panel`13.3%→`--panel-2`18.8%→`--card`22.0%) are all under 6 points, well within the ~12% dark-mode ceiling.
-- Rule 19 (outer padding ≥ inner padding) — `.panel` outer padding 18px (line 111) ≥ `.field` internal spacing 12px (line 122); `.summary`/`.table-wrap` outer padding 18px ≥ `.cards`/`.table-head` gaps of 12px (lines 264, 425).
-- Rule 23 (two typefaces max) — exactly two font families defined, `--sans` and `--mono` (`web/src/index.css:15-16`), used consistently.
-- Rule 25 (avoid adjacent hard divides) — no cases of two borders/background-transitions touching directly; dividers (`.field` border-top, `.presets` border-top) are always separated by padding from any other border.
-- Rule 27 (don't mix depth techniques) — the app uses exactly one depth technique (flat 1px borders, plus the single Rule-26-flagged ring shadow) — no mixing of soft/hard/glow styles.
-
-### Notes
-
-- The whole surface has exactly one token file (`web/src/index.css` `:root`, lines 1-18) — good centralization, no per-component duplicate palettes found in `App.tsx`, `FilterPanel.tsx`, `GameTable.tsx`, `SummaryCards.tsx`, or `TimelineChart.tsx` (no inline `style=` usage in any `.tsx` file).
-- `--accent-bg` is referenced with a fallback (`web/src/index.css:254`, `var(--accent-bg, rgba(102, 192, 244, 0.12))`) but never defined in `:root` — it always resolves to the fallback. Not one of the 28 rules, but worth fixing alongside Rule 11 token consolidation since it's effectively a phantom token.
-- Several violations (Rule 11 spacing scale, Rule 24 corner nesting, Rule 22 button padding) share a root cause: values were chosen per-component rather than pulled from a shared scale. Fixing Rule 11 first (defining a spacing/radius scale) would make the Rule 22/24 fixes mechanical rather than case-by-case.
-- `web/coverage/` and `web/dist/` contain generated/build CSS (`base.css`, `prettify.css`, `assets/index-*.css`) — excluded from this audit since they're build artifacts, not source.

+# Next session: manual-pick rules, then finish the 250-line cap
+
+Paste this whole file as the first prompt of a fresh session. Everything needed
+is below; you should not need the previous session's transcript.
+
+Repo: `~/steam-backlog-enforcer`. Work on `main`. HEAD is `0f25fba`.
+
+---
+
+## Task 1 (do this first): change the manual-pick rules
+
+kuhy hit this and wants it changed:
+
+```
+./run.sh pick-manual 3164500      -> Error: you already have 3 manual pick(s).
+./run.sh abandon-pick 495890      -> Grace period EXPIRED ... closed 3.7 day(s) ago.
+./run.sh abandon-pick 618510      -> Grace period EXPIRED ... closed 3.3 day(s) ago.
+```
+
+He is stuck: three picks locked in, and the 4-day grace window closed on two of
+them, so nothing can be abandoned and no new pick can be added.
+
+**The change he asked for, verbatim:**
+"allow to abandon pick at any time but reduce number of manual picks to max of 2"
+
+So:
+
+1. **Abandon at any time** — drop the grace-window restriction entirely.
+   - `_manual_pick_lifecycle.py:73` `can_abandon_manual_pick()` currently returns
+     `remaining is not None and remaining > 0`. It should return whether the pick
+     exists at all, regardless of elapsed time.
+   - `_manual_pick_lifecycle.py:87` `abandon_manual_pick()` has the matching
+     guard; the docstring says "if still inside its grace window" — update it.
+   - `MANUAL_GRACE_DAYS = 4` is declared in **two** places:
+     `_actions.py:33` and `_manual_pick_lifecycle.py:40`. Decide whether the
+     constant still has a purpose after this change (see "open question" below)
+     and do not leave two divergent copies.
+   - `manual_pick_grace_remaining()` (`_manual_pick_lifecycle.py:47`) also feeds
+     `status_payload()` at line 162 as `grace_days_left`, and `run.sh status`
+     prints "undoable for N more day(s)". If grace no longer gates anything,
+     that display is now a lie — either drop it or restate it.
+
+2. **Max picks 3 → 2** — `config.py:63`, `max_manual_picks: int = 3`.
+   - kuhy's `~/.config/steam_backlog_enforcer/config.json` does **not** set this
+     key, so it takes the default; changing the default is sufficient and no
+     config migration is needed. (Verified.)
+
+**Open question — ask kuhy before implementing, it changes the design:**
+He currently has **3** picks locked and the new max is **2**. What should happen
+to the existing over-cap state? Options: leave the 3 in place and simply refuse
+new picks until he abandons down to 2 (least surprising); or force him to
+abandon one now. `manual_pick_slots_left()` (`_actions.py:89`) returns
+`max_picks - len(picks)` and will go negative — check every caller handles that,
+particularly `main/picks.py:109`.
+
+**Verify by running, not just tests** (repo CLAUDE.md requires this):
+```
+./run.sh status                 # read-only, safe
+./run.sh abandon-pick 495890    # MUTATES STATE - confirm with kuhy first
+```
+`./run.sh` with **no args defaults to `done`**, which completes the current game
+and reassigns. Never run it bare. `status` and `list` are the read-only ones.
+
+---
+
+## Task 2: finish the 250-line cap campaign (user-approved, in progress)
+
+Three files remain. The gate is `bash scripts/check_file_length.sh --all`
+(**trust the exit code only** — `| tail` and `grep -c` both report misleadingly).
+
+```
+_stats.py:       523 lines (over by 273)
+scanning.py:     521 lines (over by 271)
+_web_dataset.py: 436 lines (over by 186)
+```
+
+Everything else in `pre-commit run --all-files` already passes, so these three
+are the only thing between the repo and a working `git push`.
+
+### The method that works: leaf-set extraction ONLY
+
+Extract functions that call **nothing else in their own module**. That keeps
+every new import one-way, so no cycle is possible. Splitting on any other
+boundary produced circular imports three separate times, and one of them broke
+`./run.sh` while kuhy was using it.
+
+Helper scripts from the last session (outside the repo, so they don't dirty git):
+`/tmp/claude-1000/-home-kuhy/0f40b913-131e-43b9-b353-23de8c80a8c8/scratchpad/`
+- `leaf_split.py` — run with just a module name to LIST its leaves; add
+  `--new <mod> --doc "..." --names ... --apply` to perform the split.
+- `missing_names.py` — reports names a module uses but never binds. Run it on
+  `steam_backlog_enforcer/*.py` after every split; this catches the fallout
+  immediately instead of via 30 confusing test failures.
+- `retarget.py`, `add_getattr.py` — of limited value, see the warning below.
+
+If `/tmp` has been cleared, `leaf_split.py` is ~90 lines and easy to rewrite:
+parse the module, find `FunctionDef`s whose bodies call no sibling function,
+move those plus a copy of the module header into a new file, and add a
+top-level `from ... import (...)` back in the original.
+
+### Traps that cost the last session hours
+
+- **`_web_dataset` is the hard one.** Its dataclasses (`WebGame`,
+  `WebStateInfo`, `WebDataset`, `PaceVsHLTB`, `DefaultSummary`, `WebDefaults`)
+  are used by both the parent and the helpers, so they must go to their own
+  **leaf model module** that both import — not stay in the parent. Getting this
+  wrong is what broke `run.sh`.
+- **`ruff-format` silently deletes bottom-of-file re-export imports** (the
+  comment above them survives, so it looks intact). Put re-exports at the top,
+  or serve them through a module `__getattr__`.
+- **A module `__getattr__` re-export** needs: `importlib.import_module` (a call,
+  so no `PLC0415`), and a `_Reexport: TypeAlias = Any` return annotation —
+  `object` fails mypy at the call sites, bare `Any` fails ruff `ANN401`.
+  Working examples already in the tree: `_actions.py`, `_whitelist.py`,
+  `hltb.py`, `_cmd_done.py`.
+- **Patch-target rule**: the target is the module whose **source file contains
+  the function under test** — not where a helper is defined, not where the test
+  imports from. Fix these **per file from the pytest failure list**. Six
+  attempts at bulk regex retargeting had a net effect of −11 tests; per-file
+  diagnosis worked every single time.
+- **`@dataclass` decorators**: when copying a module header, include decorator
+  lines in the boundary or you strand a bare `@dataclass` (fails with a
+  confusing `'function' object has no attribute '__mro__'`).
+- **Stale `.mypy_cache`** after moving symbols → `AssertionError: Cannot find
+  component`. `rm -rf .mypy_cache`; it is not a real error.
+
+### Non-negotiables
+
+- **Use `.ci-mirror-venv/bin/python` for pytest**, not system python3 — the
+  latter has mcp 2.0 against a pinned mcp<2, so `test_mcp*.py` cannot collect
+  and coverage reads ~97% instead of 100%.
+- Baseline to preserve: **1347 tests, 100.00% coverage**.
+- **Verify with the coverage run before committing**, not `--no-cov`. Last
+  session committed 3 failures after misreading a `--no-cov` run as green.
+- Never `--no-verify`. Never add `# noqa` without asking.
+- **The service auto-restarts from this tree** (`Restart=always`,

+### When the cap is clear
+
+`git push` (13 commits are waiting, including another session's `2ad8752` for
+`install.sh`). The pre-push ci-mirror runs `pre-commit --all-files` over the
+whole tree, which is why the cap has to be fully clear first.

+
+## Context: what the last session actually fixed (already committed, verified)
+
+`21fe2f7` + `919ecdf` — the enforcer was launching Steam **as root**, so Steam
+answered with a `zenity` modal reading "Cannot run as root user" on kuhy's
+screen. Root cause: `game_install._get_real_user()` read only `SUDO_USER`/`USER`,
+neither of which systemd sets, so it returned `None` and every
+`geteuid() == 0 and real_user` guard fell through to running as root. It also
+caused a retry storm — 1656 attempts in 30 minutes at 1.5 GB RSS. Both fixed and
+verified in production (`sudo -u kuhy env DISPLAY=:0 ... steam`, every Steam
+process at uid 1000, 0 retries, ~244 MB).
+
+Do not re-litigate that fix; it is done. Tasks 1 and 2 above are what remains.
