See whether a room is available for every night of a stay

TASK
Validate the complete fictional interval snapshot first, holding affected rooms for unknown or conflicting source intervals. Expand occupied and maintenance nights under the exact arrival/departure rule. Return the complete room-by-night grid and each request’s candidate rooms/exclusion reasons, independently. Distinguish snapshot fit from housekeeping release and any booking.

INPUT
Complete fictional snapshot only, using room and request tokens. Review nights 2026-10-14 through 2026-10-20 inclusive. Arrival date is occupied; departure date is not occupied. Rooms T1 and T2 are twins; D1 and D2 are doubles. No other stays or blocks exist in this synthetic snapshot.
S1: T1 arrives 2026-10-14, departs 2026-10-17.
S2: T2 arrives 2026-10-18, departs 2026-10-20.
S3: D1 arrives 2026-10-15, departs 2026-10-18.
M1: D2 maintenance blocks the nights of 2026-10-16 and 2026-10-17.
Q1: needs one twin, arrives 2026-10-17, departs 2026-10-19.
Q2: needs one double, arrives 2026-10-16, departs 2026-10-18.
No split-room stays. Check requests independently, not as accepted bookings. Missing departure dates, overlapping existing stays on a room, or occupancy conflicting with a block put the whole affected room on hold until the source owner resolves it. Do not silently prioritize one record. Housekeeping release, real availability and booking authority are not supplied.
END INPUT

Check the answer in this sample chat against the complete INPUT above. Mark S1 nights 14/15/16 and S2 nights 18/19; checkout nights 17 and 20 are excluded. Q1 covers 17/18 and has only T1 as a snapshot candidate. Q2 covers 16/17 and has no eligible uninterrupted double. A dot is only a snapshot cell. No real release, cleanliness, booking or current-availability claim should appear. Quote each mismatch and its source, then return a complete corrected replacement. If source or answer is missing, ask for it. Do not describe a suggested human trial as completed.

Check my complete synthetic room snapshot and proposed stays. Validate room IDs/types, dates and intervals first; hold each affected room for missing essential endpoints, overlapping existing stays or occupancy/block conflicts until the owner resolves the source. Apply my stated arrival/departure boundary, expand every room-night across my horizon, then list each request’s uninterrupted candidate rooms and exclusion reasons. Check requests independently unless my rules explicitly define an allocation problem. Derive requested nights, types and counts from MY INPUT; never use practice dates. Independently mark every interval on a calendar and compare each requested night. Keep release status and live availability unverified and do not allocate, release or book rooms.

MY INPUT
Fictional room IDs/types: [replace with your source or rule]
Complete dated existing occupancy intervals: [replace with your source or rule]
Maintenance blocks and their dates: [replace with your source or rule]
Arrival/departure boundary rule: [replace with your source or rule]
Proposed stay requirements: [replace with your source or rule]
Snapshot scope and unknown/conflict policy: [replace with your source or rule]

Use only MY INPUT for facts, quantities, names, dates and permissions. Ask for missing essential facts or conflicting rules instead of guessing. Creative invention is allowed only where this task and my boundaries permit it. Return the actual complete requested result, a separate unknown/hold list and the source-specific review described above. Do not reuse practice-example facts. Keep this a draft; do not publish, contact people, book, buy or change another service.
