The next hotel starts from what you leave
Harbor by Signalry stays hotels only. A description, a claim, and a reported result each leave a stable id behind. Nothing here is a price, a customer, or a verification.
Buyer
Describe your job
No account. Harbor by Signalry opens the closest catalog brief, when not to buy, and a shortlist. A weak sentence stays on the catalog.

About
Twin Book is a demo-shaped inventory guard. It compares PMS and CRS availability on a clock. When the books disagree, it pages a named owner. It will not auto-close a channel or rewrite a reservation.
AdviceAn auto-fix that moves a guest is a second inventory owner.
Best for
Tech leads who already know they have two truths.
Not for
A house still on a PMS with no availability API.

Evidence
- · Disagreement is a ticket, not a silent write.
- · Named owner required or the product will not go live.
Tradeoffs they name
- · Adds noise if your two books are already a mess.
- · Not a replacement for a real CRS cutover.
