A sync deleted the rows a re-plan had dropped only after apply_proposed_days
had already validated, so capacity being freed in the very same call was
never counted. Shortening one period and lengthening another while near the
pool cap read as pure net-new demand and was refused outright, writing
nothing and losing the edit silently.
apply_proposed_days now takes the keys it should delete, credits those rows
back to their tier and to the dubbeldagar quota during the up-front checks,
and performs the deletions in its own write phase. Validation still runs
fully before any write, which is what SQLite's lack of a cross-request
transaction requires.
The calendar is becoming the plan: a user edits a period and the schedule
updates immediately, with no separate propose and apply steps. POST
/api/plan/sync does both and returns a per-date diff against a snapshot taken
before any write, so the interface can say what actually moved rather than
guessing from coarse counters.
Pinned days now mean something. A day the user hand-edited keeps its type and
its parent: the loader hides unpinned wish-attributed rows from the allocator
so a re-plan is free to move them, while pinned rows stay visible and the
existing occupancy check refuses to touch them. Their cost is debited off the
pool before any window is funded, following the precedent already set for
preschool planning days.
Propose and apply are untouched. The allocator stays pure.
