Capacity, vessels, suppliers
on one read-only window.
Marina capacity, vessel traffic, holds, and supplier-of-record on one Bahamian-hosted ledger. Procurement awards are append-only with a 7-year retention window. Yatlas’s authority desk reads from the same chart the dockmaster runs — no parallel system, no reconciliation drift.

§ 02 · 3-STEP MANIFEST · QUERY → READ → AUDIT
The authority’s window, in three lines.
Query the operating layer for capacity. Read the same append-only ledger the marinas post to. Audit procurement awards with full provenance — the same chart, scoped to the role that opened it.

§ 01
QUERY
Capacity, on demand.
Marina occupancy, vessel traffic, slip availability, and active holds across all 13 partner marinas — queryable from a read-only console. Granted roles see the chart the dockmaster runs, not a stale weekly export.

READ
The ledger as system of record.
Every booking, hold, settlement, RFQ award, and runner dispatch posts to an append-only ledger. The Port Department, Customs, and Tourism each see the rows scoped to their grant. Bahamian-domiciled storage; 7-year retention.

AUDIT
Procurement, with provenance.
Every RFQ award, supplier-of-record, and runner dispatch carries the rule, the bidder set, the timestamp, and the operator who pressed the button. The audit packet exports as a single PDF or CSV — Port Department-formatted out of the box.

§ 03 · CAPACITY WINDOWREAD-ONLY · 13 MARINAS · LIVE GRID
One window onto the dock plan of every partner marina.
Authorities don't run a parallel system — they read the same grid the marinas post to. Slip occupancy, holds, vessel traffic, and dockside overrides surface in real time, scoped to the granted role. The Port Department sees the chart the dockmaster runs, not a stale weekly export.
13-marina rollup
Bay Street, Highbourne Cay, Albany, Bimini, Treasure Cay, more — one consolidated capacity view.
Live occupancy + holds
Booked, hold, blocked, open — every state visible, every state stamped with timestamp + operator.
Vessel manifest · per port
Active vessels, arrival-departure ETA, papers status. Surfaced when the captain books, refreshed at clear-in.
Capacity report · scheduled
Daily, weekly, monthly PDF/CSV pulls. Format aligned to Port Department + Tourism reporting templates.
Read-only by design
Authority roles cannot mutate state. The ledger is append-only; reads do not affect operator workflow.
Filterable scope
Filter by jurisdiction, port-of-call, vessel size, flag — the read window scopes to the analyst's question.

The same ledger. Scoped to the role that opened it.
Yatlas does not run a parallel database for authorities. The read window is a scoped view over the same append-only ledger the marinas post to. Grants are role-based; retention is Bahamian-domiciled; exports run in the formats Port Department and Customs already file.

§ 05 · PROCUREMENT AUDITAPPEND-ONLY · RFQ · AWARD · DISPATCH
Every award, with the rule, the bidders, and the operator who pressed the button.
Procurement is the deepest audit surface Yatlas exposes. Every RFQ opens with a bidder set; every award stamps the rule, the supplier-of-record, and the operator. Runner dispatch carries the GPS log. Authorities read the same ledger the captain and the MSME post to — no second system, no reconciliation drift.
RFQ provenance
Open → bidder set → quotes → award. Every state stamped with timestamp, operator, hash.
Supplier-of-record
Awarded MSME stays of record on the ledger row. Licence number, jurisdiction, contact stamped.
Award rule trace
Why this supplier? Lowest quote · highest rating · proximity rule · operator override — surfaced.
Runner dispatch · GPS
Pickup, route, drop-off — timestamped GPS log per dispatch. Append-only on the same ledger.
Audit packet · 1-click
Per-RFQ or per-period PDF/CSV pull — all bidders, all quotes, the award rule, the dispatch log.
MSME catalog provenance
Each catalog entry carries licence + jurisdiction at the time of award. Historical accurate.
