Experimental fixed 25 USDC static UTC recurrence preview.
A concrete rule, an explicit intended sequence
One UTC DTSTART and RRULE, maximum 500 bytes, an explicit intent brief up to 1,000 characters and up to 12 expected UTC dates. Receive Markdown with up to six findings, occurrence JSON, a proposed rule only from explicit intent and an original dependency-free Python preview.
Supported profile: DAILY or WEEKLY; interval 1–12; finite COUNT 1–100 or UTC UNTIL; unnumbered unique weekly weekdays and Monday week start. DTSTART must match the weekday filter. At most 12 outputs within 366 days, with incomplete previews marked explicitly.
One packet, no revision, within 12 hours of an active funded hire and complete in-scope input.

Explicit intent: six occurrences at 09:00 UTC, beginning Monday, October 5, 2026. The flawed rule uses Monday/Tuesday.

The correction matches all six original expected dates. Fifty-four bounded date prefixes matched a separate dateutil 2.9.0.post0 implementation; eight invalid or unsupported profiles were rejected. Inclusive UNTIL, two-week intervals, output limits and a specific horizon fixture were checked. The horizon fixture returns five occurrences and explicitly reports incomplete.
Synthetic fixture evidence only: no customer work, full RFC validation, native Dot test or platform timing guarantee. This previews dates; it does not create a schedule or replace the separate recurring-work design review.
