Second real bug found by driving the running app while the suites were green.
Flexible wishes were funded twice across propose -> apply -> re-propose. Because
planned_leave_day carries no wish_id, the engine could not tell that applied days
were that wish's own prior occurrence; it treated them as occupied space, routed
the candidate search around them, and funded the year again on shifted dates while
reporting weeks_funded 1.0. Applying twice turned "one week each spring" into 18
paid days instead of 9. Fixed wishes were unaffected and stay unaffected.
Fix (allocation_service.py), per the approved approach of counting already-applied
days inside the bounding range rather than adding a wish_id column:
- _Ledger._persisted_lookup snapshots existing days BEFORE this run folds in its
own freshly-computed windows, so a fixed wish's new placement is never mistaken
for a flexible wish's history
- _reuse_already_funded_window finds this wish's persisted dates within its bound
and reuses the window containing them, via the ordinary fund_window path
- full funding therefore yields zero new days and partial funding tops up exactly
the remainder, with no duplication and no false shortfall
- with no persisted dates, or if the reused window is no longer collision-free, it
falls through to the original search, so an unsatisfied year is never frozen
Calendar cache extended 2026-2035 -> 2026-2055 (39KB -> 116KB) and the allocator
switched to strict, so an uncached year raises UncachedYearError -> ValidationError
-> HTTP 422 instead of silently treating Julafton, Nyarsafton and Midsommarafton as
working days. Also fixed normalize_day dropping the second name when two holidays
share a date (Nationaldagen was being lost). 2049 and 2055 legitimately have 17 red
days, not 18: Pingstdagen coincides with Nationaldagen.
New backend/tests/integration/test_user_journey.py drives the real app over HTTP
across seven journeys: the double-booking guard, the fixed-wish control, apply
idempotency, fixed-never-displaced-by-flexible, flexible wishes tracking Easter
per year, age-4 arithmetic self-consistency, and a recursive check that no Swedish
text reaches the wire now that everything is message_key + data.
New backend/scripts/seed_demo.py seeds a realistic workspace through the real
service layer for manual testing: demo@example.com / DemoPass123!
Backend 414 -> 435 tests. Frontend unchanged at 705.
Still not verified in a browser.
