- parseInt(month/year) now passes radix 10 consistently.
- minGap eligibility guards null/undefined (c.minGapDays != null && > 0).
- The corrupt-localStorage load and the createEmployee catch now console.warn
instead of swallowing the error silently.

New js/utils.js exports toISO, monthPrefix, getWeekday, formatDateDE and
buildNameMap. algorithm.js, calendar.js, excel.js and history.js now import
these instead of re-implementing ISO construction, weekday math, DD.MM.YYYY
formatting and the id→name map inline. Adds tests/utils.test.mjs.

- saveState is now debounced (~400ms) to coalesce rapid changes; a pending
write is flushed on beforeunload and on visibilitychange→hidden so the last
change is never lost.
- The SheetJS <script> gets defer so it no longer blocks initial parse; the
typeof XLSX guard already covers any not-yet-available case.
Verified headless: app loads without JS/CSP errors.

Extracts the day-cell construction into a self-contained makeDayCell(d). Slot
changes and holiday/closure toggles now replace just that one cell
(cell.replaceWith) plus update export-button visibility, instead of rebuilding
the entire month grid and re-attaching every listener on each interaction.
Structural changes (month/year/slot-count) still do a full render.
Faithful extraction; verified headless that the page loads without JS errors
and tests pass. Interactive render coverage to follow in the test-layer issue.

- generatePlan computes a histCount Map once; scoreCandidate now does an O(1)
lookup instead of filtering the whole history per candidate per day.
- minGap eligibility finds the latest prior date in a single pass instead of
spreading history+monthAssignments into a new array and sorting it.
Behaviour is unchanged (all algorithm tests pass).

- README gains a "Datenschutz & Speicherung" section: local single-user tool,
unencrypted localStorage, avoid shared devices, export JSON to back up.
- Comments the generateId Math.random fallback as a non-crypto last resort,
acceptable for local employee ids.

Adds sanitizeCell(): cell values starting with = + - @ or a control char are
prefixed with an apostrophe so spreadsheets render them as literal text
instead of executing them as formulas. Applied to the names column.

removeEmployee now also filters the deleted employee's history entries, so
no orphaned "(unbekannt)" rows remain. Adds a test.

saveState now logs a console.warn on failure and alerts the user once per
session (storage full/unavailable) so they can export their data and avoid
silent data loss.

- loadFromJSON and the localStorage startup load now run employees through
normalizeEmployees(): fills missing constraints, drops unusable rows,
de-duplicates ids, and discards invalid vacation ranges — preventing
later crashes (e.g. c.neverDays on undefined) and same-day double-books.
- Excel import is wrapped in try/catch with a typeof XLSX guard and user
feedback; the Excel export button gets the same guard.
- createEmployee reuses the shared defaultConstraints() factory.
Adds normalizeEmployees tests (defaults, dropping, dedup, vacations) and a
loadFromJSON normalization test.

generatePlan gains a preAssigned parameter: manual entries occupy slots,
count toward eligibility (maxPerMonth/minGap) and are never double-booked;
only the remaining slots per day are auto-filled. The generate handler now
keeps manual:true entries for the month instead of wiping them.
Adds tests for slot occupation, fully-manual days, and maxPerMonth counting.

currentYear now initializes to the current year and the year selector
offers a rolling range (this year -1 to +2) so plans can be created
for years other than 2026.
