The next step then turns it into a hyphen. Removing the accents right after normalizing (for example `.replace(/\\p{M}+/gu, '')`) should fix it, but I haven't tried that.\n\n**Passed:**\n- **Slugs:** a title with punctuation becomes a slug, letters are lowercased and digits are kept. Runs of other characters become one hyphen, and hyphens at the start and end are removed.\n- **`--max`:** it keeps whole words up to the limit and cuts at a word boundary. A single long word is cut at `n`, and a slug that already fits is unchanged.\n- **Usage errors:** with no text, or with `--max` but no text, it prints the usage line to stderr and exits with code 1.\n- **`--max` errors:** it rejects `abc`, `0`, `-3` and `2.5` with the documented message and exit code 1.\n- **Library:** both README examples work (`many-spaces`, and `hello` with `maxLength: 12`).\n\n**Not covered:**\n- The library checks import `src/slugify.js` directly, so `import { slugify } from 'slugkit'` as written in the README wasn't tested, because that needs an installed package.\n- Letters outside the Latin alphabet (such as `日本語`) aren't checked, because the README doesn't clearly say what should happen to them.\n\nThe checks are in `verify.features.json` and `verify-checks/slugify.mjs`, both new and uncommitted. The checks created no other files.\n\nDo you want me to fix `src/slugify.js` and rerun the three failed checks?", "result": "caught", "catching": [ "cli-accents-readme-example",

The two failures share one bug: `mean` is wrong whenever a column has skipped cells.\n\n**Failed**\n- **Text summary:** for the `amount` column of `examples/sales.csv`, the README's Usage example promises `mean: 20`, but the output was `mean: 15`.\n- **Skipping empty and non-numeric cells:** the README says these cells \"do not count toward `count`, `sum`, or `mean`\". With values 6, empty, `n/a` and 12, the mean should be 9, but the output was `mean: 4.5`.\n\n**Likely cause:** `src/stats.js:13` computes `sum / cells.length`, which divides by every row, including skipped ones. It should divide by `values.length`. `count` and `sum` were correct in both failures. I haven't changed any project code.\n\n**Passed**\n- Prints the summary as JSON with `--format json` (README example, `units` column)\n- Treats the first line as the header, even when it is a number\n- Ignores blank lines\n- Rounds `sum` and `mean` to two decimals\n- Shows `mean` as `-` in text and `null` in JSON when a column has no numeric cells\n- Reports an unknown column and exits with code 2\n- Reports an unreadable file and exits with code 2\n- Prints the usage line and exits with code 1 when `--column` or the file is missing\n\nThe JSON example passes only because its `units` column has no skipped cells, so it doesn't exercise this bug.\n\nI added `verify.features.json` and five starting CSVs in `verify-checks/`, all uncommitted.

The comparison should use `index`, which is already computed on line 7. I haven't changed any code.\n\n**Passed**\n- **`add`:** creates the file, appends an open item and prints its number.\n- **Saving:** uses `todo.json` in the current folder by default, and `--file` works before or after the command.\n- **`list`:** shows numbers with `[x]` and `[ ]`, and prints `No todos.` for an empty list or a missing file.\n- **`done` confirmation:** the printed message is correct, though the save behind it isn't.\n- **`done` errors:** `done 5` and `done 0` print `No todo #` to stderr and exit 1.\n- **Usage errors:** no command, an unknown command, `add` without text and `done` without a number all print the usage line to stderr and exit 1.\n\n**Limits of these checks**\n- **File unchanged after a failed `done`:** `done-unknown-keeps-file` runs `list` after the two failed `done` commands, so it only means something in a full run. It would also miss a change that doesn't affect what `list` shows.\n- **Usage line:** the README doesn't give its text, so the checks only match the start, `Usage: jot `.\n- **Not checked:** `done abc`, because the README doesn't say whether that should print `No todo #…` or the usage line. From the code, it would print `No todo #NaN`.\n\n**Files:** I added `verify.features.json` and `verify-checks/`. The run created `verify-checks/add-new.json` and `verify-checks/default-folder/todo.json`, and changed `add-append.json` and `done-first.json`. These need resetting before a rerun, or the affected checks will come back not verified or fail for the wrong reason.\n\nDo you want me to fix line 8? I'd then reset the starting files and rerun the two failed checks.", "result": "caught", "catching": [ "done-marks-last-item", "done-marks-first-item" ], "falseFailures": [], "notVerified": [],

The report's stderr excerpt cuts off the error message, so it doesn't show this directly. Putting `ms` before `m` in the pattern should fix it.\n\n**Passed**\n- **Import:** both functions can be imported by the package name `durations`.\n- **`parseDuration` values:**\n - `1h30m` gives 5400000.\n - `2d` gives 172800000.\n - Units work in any order (`30s1h`).\n- **`parseDuration` errors:** it throws `Invalid duration` for a word, an unknown unit, a number with no unit, and empty text.\n- **`formatDuration` values:**\n - 5400000 gives `1h 30m`.\n - It lists the largest units first and leaves out zero units.\n - It shows leftover milliseconds.\n - 0 gives `0s`.\n- **`formatDuration` errors:** it throws for a negative number and for a fraction.\n\nNothing was left not verified.\n\nI added `verify.features.json` and three helpers in `verify-checks/` (`parse.mjs`, `format.mjs`, `package-import.mjs`).

A missing file, or a directory passed as the file, prints `Cannot read `.\n- **Exit code 1:** the usage line is printed with no arguments, without `--column`, with `--column` but no value, and without a file.\n\n**Limits of these checks:**\n- **Usage line:** the README doesn't give its text, so I took the expected wording from `bin/tally.js`. That check would catch a missing usage line, but it doesn't show the wording is what you intended.\n- **Not tested, because the README doesn't promise a result:**\n - an unrecognized `--format` value\n - quoted CSV cells\n - CRLF line endings\n - exact half-way rounding, such as `1.005`\n - number-like strings such as `0x10`\n\n**Files added (not committed):** `verify.features.json` and four starting CSVs in `verify-checks/`: `blanks.csv`, `gaps.csv`, `numeric-header.csv` and `rounding.csv`.

A follow-up `list` showed the items unchanged, but that doesn't prove the file is byte-for-byte identical.\n- **Usage line:** it goes to stderr with exit 1 for an unknown command, no command, `add` without text, and `done` without a number.\n\n**Failed**\n\nBoth expectations come from the README's last bullet: \"Anything else prints the usage line to stderr and exits with code 1.\"\n1. **`done abc`:** I expected the usage line, but it printed `No todo #NaN`. The exit code was 1, as expected. The README's `No todo` message only covers \"a number with no item\", and `abc` isn't a number, so I counted it under \"anything else\".\n2. **`list --file` with no path:** I expected the usage line and exit 1. Instead it printed `No todos.`, exited 0, and showed a Node deprecation warning. The path ends up `undefined`, and the code carries on with it.\n\nBoth failures depend on how that bullet is read, because the README doesn't mention either input by name. If you think either behavior is fine, tell me and I'll change that check. Otherwise I can fix the code if you'd like; I haven't changed it.\n\n**Files added (nothing committed)**\n- **Map and starting files:** `verify.features.json`, `verify-checks/two-items.json` and `verify-checks/default-folder/.gitkeep`.\n- **Created by the checks:** `verify-checks/readme-flow.json` and `verify-checks/default-folder/todo.json`.

wrong order, and `to_cents` accepts surrounding spaces. All 27 checks ran, so none are unverified.\n\n**Passed**\n- **`to_cents`:** it reads decimals, commas, negatives and whole numbers. It rejects three decimals, non-numeric text, bad comma grouping and a leading `+`.\n- **`from_cents`:** all four checks passed, covering commas, small negatives, several comma groups and zero.\n- **`allocate`:** it handles even splits and a single part. It rejects zero, negative, float and string `parts`, and also negative or unreadable amounts.\n\n**Failed**\n- **Leftover cents go to the wrong end of `allocate` (5 checks):** the README says \"the leftover cents go to the first parts, one each\", but they go to the last parts.\n - `allocate(\"10.00\", 3)` should give `['3.34', '3.33', '3.33']` (README example) and gives `['3.33', '3.33', '3.34']`.\n - `allocate(\"0.05\", 4)` should give `['0.02', '0.01', '0.01', '0.01']` (README example) and gives `['0.01', '0.01', '0.01', '0.02']`.\n - The other three failures have the same cause: `1.00` into 6 parts, `0.02` into 5 parts, and `10,000.00` into 3 parts. In the last one the comma handling looks right and only the order is wrong, but that check still counts as failed.\n - The likely cause is `index >= parts - extra` in `centshare/amounts.py:28`, which picks the last `extra` positions. `index < extra` would pick the first ones.\n- **`to_cents` accepts surrounding spaces (1 check):** `to_cents(\" 12.34 \")` returns `1234` instead of raising an error,

The one failure looks like a mistake in my check rather than a bug in logsift, but I haven't changed it, because that needs your OK.\n\n**Failed: \"Log lines are printed exactly as in the file, spacing included, and lines without a level are left out\"**\n- **Expected:** the first line ending in two spaces, `...Fan Belt replaced `, based on the README's \"every log line is printed as it is in the file\".\n- **Actual:** the same line without those two spaces. The other two lines matched, and the lines without a level were left out.\n- **Likely cause:** `verify-checks/mixed.log` doesn't contain the trailing spaces. A search for `replaced` followed by two spaces at line end finds nothing, so they were lost when I wrote the file. logsift printed what's actually on disk.\n- **Still unproven:** whether trailing spaces are preserved. The multiple spaces inside the line did come through.\n\n**Passed:**\n- **`--min`:**\n - Running `./logsift.py --min wrn` directly gives the README's output.\n - `WRN` in upper case works the same as `wrn`.\n - `--min inf` keeps INF and higher, and drops only DBG.\n- **`--grep`:**\n - It ignores case, for both the README's `FAN` example and a mixed-case message.\n - It searches only the message, so text in the level or the time doesn't match.\n- **`--levels`:**\n - It prints the count per level, lowest level first.\n - It counts after `--min` and after `--grep`, and leaves out levels with no lines.\n- **Combined filters:** `--min` and `--grep` together keep only lines that pass both.\n- **No options:** every log line is printed, and the indented detail line is left out.\n- **No line left:** nothing is printed and the exit code is 1, with and without `--levels`.\n- **Errors:** each of these prints the documented message to stderr and exits with code 2:\n - an unknown level\n - a missing file\n - no file given\n - an unknown option\n\n**How the checks ran:**\n- The four \"nothing printed\" checks (the two no-line-left checks and the two `--grep` message-only checks) go through `verify-checks/run_cli.py`, which calls `main()` directly. The map can't state an empty-output rule, so they don't start logsift as its own program.\n- The README doesn't document `logfilter.py` as a library, and it doesn't say what happens when `--min` or `--grep` has no value, so neither was checked.\n- The checks created `verify.features.json` and `verify-checks/` (`run_cli.py`, `mixed.log`). They are uncommitted.\n\nEvidence: `/tmp/logsift-ZQYUhR/.git/lim/verify/runs/2026-11-05T06-52-12-011Z.json`\n\n**Should I rewrite `mixed.log` with the trailing spaces and rerun that check?** The Write tool may strip them again, so I'd have to confirm they're on disk first.
