+# Calendar widget (PR #970) — session handover
+
+_Working notes for picking this back up. **Delete this file before merge.**_
+
+Branch: `wip/calendar-widget` (winter core) · tip when written: `170649685 wip`
+Companion: `wintercms/wn-test-plugin` branch `wip/calendar-events` → **PR #25**
+Core PR: **wintercms/winter#970** — un-drafted, CI green, ready for review.
+
+---
+
+## TL;DR
+
+The widget is **working end-to-end and browser-verified**. The roadmap in #970's comment is done except the two explicitly-optional items (full de-vendor of FullCalendar into the build; a broader in-repo Dusk suite). The PHP surface stayed stable as intended; the real work was assets, the Snowboard/v6 JS port, recurrence/timezone, tests, docs — plus fixing several latent bugs the browser pass surfaced.
+
+Automated coverage: **33 tests green** — 15 `CalendarWidgetTest` + 4 `CalendarControllerTest` + 9 `EventDataTest` (core) + 5 `EventCalendarTest` (test plugin).
+
+Screenshots + a screen recording of the working widget: `~/Repositories/WinterCMS/Core/calendar-pr-screenshots/` (`01-month-view.png` … `08-event-edit-form.png`, `calendar-walkthrough.webm`).

+
+---
+
+## Key decisions
+
+- **Build = laravel-mix, not Vite.** The roadmap said "Vite pipeline" but this module builds JS/LESS with `modules/backend/winter.mix.js`. The calendar bundle compiles `assets/js/src/*.js` → `assets/js/dist/calendar.js`, registered in `winter.mix.js` next to the other widgets. `loadAssets()` serves `js/dist/calendar.js`.
+- **FullCalendar stays vendored (v6.1.15)** at `assets/vendor/fullcalendar/*`; the plugin uses the `FullCalendar` global. Full de-vendor into npm+mix was deliberately **skipped** — the dead v4 tree (the big diff win) is already gone; the remaining bundle is the real library, so de-vendoring is marginal diff-for-risk. Optional follow-up.
+- **Recurrence = server-side (roadmap option b), default-safe.** `applyDateRangeFilter` (config, default `true`) + `setApplyDateRangeFilter(false)` let a consumer keep recurring masters in the query and expand them in `backend.calendar.extendRecords`. Additionally `extendQueryBefore`/`extendQuery` now receive the visible window so consumers can write an efficient recurrence-aware query (`window-intersecting OR has-rrule`). Client-side `rrule` (option a) is documented as an alternative.
+- **Timezone**: `timezone` config controls event output (offset-qualified ISO) and is surfaced via `data-timezone`; defaults to `app.timezone`. `moment-timezone` dropped (was in the deleted v4 tree); v6 handles local/UTC natively — **named zones need a FC named-tz plugin** we don't ship (documented).
+- **Snowboard port keeps the month-window cache** (`CalendarCache`, moved to an ES module) and bridges to the **still-Storm** toolbar-search/filter widgets via jQuery framework events.
+
+---
+
+## Bugs found & fixed in browser testing (the important part)
+
+All were latent in the original port; the browser pass surfaced them.
+
+1. **Month cache timezone mismatch** (`CalendarCache.getMonthRequestData`) — computed day-of-week / month boundaries with the *browser's* local zone while FullCalendar reports timestamps in the *calendar's* zone. When they differ the "is this a month grid?" check failed and snapped to the wrong 42-day window → FullCalendar got the wrong month's events. Now does the math in the calendar's frame (UTC when the calendar runs in UTC).
+2. **Point events (null end) dropped** — twice: the SQL filter (`recordEnd >= start` is NULL) and the client bucketing (`Date.parse(undefined)` = NaN). Both now treat a missing end as ending at the start. Core fix in `applyDateRangeToQuery`; JS fix in `saveFirstThreeMonthsData`.
+3. **Search/filter wired to the wrong framework events** — the Storm framework fires **`oc.beforeRequest`** (not `wn.beforeRequest`), so the current month window was never injected into search/filter requests and recurring events vanished on search; and the onRefresh payload arrives via **`ajaxSuccess`** (`[context, data, …]`), not the jQuery-native `ajaxComplete`. `onFilterUpdate` now scans its args for the payload rather than assuming a position.
+
+After these: month/week/day/list, month paging + cache, event click → edit form, search, all-day & date-range filtering, and recurrence expansion all work with **zero console errors**.
+
+---
+
+## How to build the JS/CSS
+
+```bash
+cd modules/backend
+export PATH="$(git rev-parse --show-toplevel)/node_modules/.bin:$PATH"
+# whole backend bundle (Snowboard, widgets, …):
+mix --production            # or: mix   (dev, unminified)
+```
+To build **only** the calendar during iteration (avoids rebuilding every widget's dist), use a throwaway config:
+```bash
+cat > calendar.mix.js <<'JS'
+const mix = require('laravel-mix');
+mix.setPublicPath(__dirname);
+mix.js('./widgets/calendar/assets/js/src/Calendar.js', './widgets/calendar/assets/js/dist/calendar.js');
+JS
+mix --production --mix-config=calendar.mix.js
+rm -f calendar.mix.js mix-manifest.json      # mix-manifest.json is NOT tracked — don't commit it
+```
+`calendar.css` is compiled from `assets/less/calendar.less` (registered as a LESS bundle in `ServiceProvider::registerAssetBundles`).
+
+## How to run the tests
+
+Use the **root** phpunit config, not `modules/backend/phpunit.xml` — the backend config declares no bootstrap, so the Winter ClassLoader isn't registered and new fixtures (`CalendarEventFixture`) fail to autoload.
+```bash
+vendor/bin/phpunit modules/backend/tests/widgets/CalendarWidgetTest.php
+vendor/bin/phpunit modules/backend/tests/widgets/EventDataTest.php
+vendor/bin/phpunit modules/backend/tests/behaviors/CalendarControllerTest.php
+vendor/bin/phpunit plugins/winter/test/tests/EventCalendarTest.php
+```
+Run **phpcs before pushing** (CI's "PHP" job): `vendor/bin/phpcs -nq --extensions=php <changed .php files>`; `vendor/bin/phpcbf` autofixes. The original calendar code had 31 style violations (inline control structures, spacing).
+
+## How to browser-test
+
+- Site: `https://winter.test` (Herd, MySQL `winter.test`). Backend admin created for automation: **`claude-test` / `ClaudeTest1234`** (superuser — delete when done).
+- **Serving quirk:** the docroot is a Winter **public mirror** (`public/` = symlinks). After adding a *new* directory (e.g. the calendar widget dir or a new plugin), run **`php artisan winter:mirror public`** or its assets 404 (served as HTML → Chromium `ERR_BLOCKED_BY_ORB`, silent).
+- Playwright is installed (chromium + ffmpeg). Reusable helper + the scripts I used are in this session's scratchpad (`pw-lib.js`, `cal-*.js`) — they log in, drive views/search/filter, and record video/screenshots. Run node with `NODE_PATH=<repo>/node_modules`. (Memory also notes a chrome-devtools-MCP + `vite:watch` HMR loop as the preferred fast loop for *other* assets, but the calendar bundle is mix, so rebuild with `mix` between JS edits.)
+
+Seed demo data (August 2026, incl. recurring masters that start before the window):
+```bash
+php artisan tinker   # then create Winter\Test\Models\Event rows; see EventCalendarTest for shapes
+```
+
+---
+
+## Test plugin (wn-test-plugin, PR #25)
+
+Adds the fixture the calendar was verified against (supersedes the closed draft #21):
+- `models/Event.php` — `winter_test_events` + a minimal RRULE expander `expandOccurrences()` (`FREQ=DAILY/WEEKLY/MONTHLY`, `INTERVAL`, `COUNT`, `UNTIL`; UNTIL compared by day).
+- `controllers/Events.php` + `controllers/events/*` — CalendarController + List/Form, toolbar, search, all-day + date-range filter.
+- `Plugin::boot()` wires the recommended server-side recurrence pattern for Event calendars.
+- `tests/EventCalendarTest.php`, a migration, and a nav item.
+
+Gotchas for that repo:
+- Its `origin` is **SSH** (no key here) — I pushed over HTTPS: `git push https://github.com/wintercms/wn-test-plugin.git wip/calendar-events`.
+- Your unrelated WIP there (Record.php, `v2.2.0/` translate-demo migration) was **left untouched** — I staged only calendar files and committed `version.yaml` with *only* my `2.3.0` entry via `git update-index --cacheinfo` so your `2.2.0` stayed uncommitted. If you switch that plugin back to `main`, your WIP restores cleanly.
+
+---
+
+## CI notes
+
+- **PHP** (phpcs) is green after `c851e192a`. **JavaScript** (eslint) is green — eslint ignores the widget `assets/` paths by pattern, so the ported JS isn't linted.
+- **Sub-split** flaked once (`splitsh-lite` >60s splitting `modules/system`) then passed on retry — infra timeout, not a code issue.
+- CodeRabbit runs now that the PR is un-drafted (was skipped while draft).
+
+---
+
+## Remaining / follow-ups
+
+- [ ] (optional) De-vendor FullCalendar v6 into the mix build; pull locales from `@fullcalendar/core/locales-all`.
+- [ ] (optional) Broader in-repo Dusk e2e (PR #25 is the fixture).
+- [ ] Named-timezone display needs a FullCalendar named-tz plugin if you want non-local/UTC zones rendered correctly.
+- [ ] Review the `170649685 wip` CSS recompile and fold it into a real commit / squash before merge.
+- [ ] The `recordColor` docblock in `Calendar.php` still says "the default background color in the calendar.less" — fine, just noting.
+
+## File map
+
+- Behavior: `modules/backend/behaviors/CalendarController.php` (+ `calendarcontroller/partials/_container.php`, `docs/example.*`)
+- Widget: `modules/backend/widgets/Calendar.php`, `widgets/calendar/classes/EventData.php`, `widgets/calendar/partials/_calendar.php`

+# (b) Server-side expansion (recommended default) - set `applyDateRangeFilter: false` (or call
+#     $calendarWidget->setApplyDateRangeFilter(false) from a backend.calendar.extendQueryBefore
+#     listener) so recurring master rows survive the query, then expand them into concrete
+#     occurrences for the window in a backend.calendar.extendRecords listener. Keeping the
+#     window constraint out of the base query also keeps the client-side month cache key stable.
+#     The extendQueryBefore / extendQuery events receive the visible window ($startTime,
+#     $endTime as Unix timestamps) so you can add a recurrence-aware constraint that still keeps
+#     non-recurring rows efficient, e.g. "rows intersecting the window OR rows with an rrule".

+# ===================================
+# Record on click

+# The handler receives the following arguments:
+#   data:      a plain object { startDate, endDate, event, eventEl }
+#   startDate: a JS Date object
+#   endDate:   a JS Date object, may be null
+#   event:     the FullCalendar event object (id, title, start, end, ...)
+#   eventEl:   the HTML element for this event
+# recordOnClick: $.wn.eventCalendar.onEventClick(:data, :startDate, :endDate, :event, :eventEl)
+
+# Triggered when the user clicks on a date or a time.
+# The handler receives the following arguments:
+#   data:    a plain object { date, dateStr, allDay, dayEl, event, view }
+#   date:    a JS Date object for the clicked day/time
+#   dateStr: an ISO-8601 string representation of the date
+#   allDay:  true or false
+#   dayEl:   the HTML element representing the clicked day
+#   event:   the native JS event (click coordinates, etc.)
+#   view:    the current view @see https://fullcalendar.io/docs/view-object
+onClickDate: $.wn.eventCalendar.onClickDate(:data, :date, :dateStr, :allDay, :dayEl, :event, :view)
