• Seat: grok-4.7 / xhigh (adversarial review wave 7, 2026-10-25)

• Category: [FIX]

• Problem / Opportunity: The 07:00 London digest asks the filter for today | overdue, then splits that list by comparing the raw deadline text with today's date. A datetime sorts after the date-only string "YYYY-MM-DD", so an instant that has already passed is filed under DUE TODAY. A deadline overdue cannot read (julianday is NULL, including a 10-character string that only looks like a date) is filed there too. docs/dsl.md says those rows are overdue.

• Evidence: On the unfixed split, with the deadline written by SQL after create (create normalises an offset into UTC and hides the comparison):

a datetime already past must be overdue even when its text starts with today, got:
☕ pTask digest 2026-10-25

📅 DUE TODAY (1)
  PT-1 [normal] missed earlier today 2026-10-25T00:00:00+14:00

2026-10-25T00:00:00+14:00 is 10:00 UTC the previous day. SQLite agrees the instant is before noon UTC:

The same split files not-a-date and abcd-ef-gh under DUE TODAY (abcd-ef-gh sorts after 2026-10-25):

  PT-1 [normal] deadline shaped like a date abcd-ef-gh

The overdue arm in crates/ptask-core/src/filter.rs is julianday IS NULL, or a 10-character date before today, or a longer datetime whose julianday is before now. docs/dsl.md states the same rule.

• Change: morning_row_is_overdue keeps a real YYYY-MM-DD date on the date-only rule (due all day). Any other deadline is overdue once dates::parse_iso_to_utc says its instant is before now, and overdue when that parse fails. An empty deadline stays under DUE TODAY, so a row included only because due_at is today is unchanged. Version 3.51.6 in the workspace package, the six internal requirements, Cargo.lock, and docs/gen/pt.1.

• Verification: On this branch, toolchain 1.98.1:

The workspace suite, native-ml, and the dashboard sidecar were not run.

• Risk & rollback: Only the morning-digest partition changes. Evening recap, the filter SQL, and task storage are untouched. Revert is one commit: v3.51.6: count a passed datetime as overdue in the morning digest.
