# VeloceDB 2.73.24 — cursor-bind analog leftover

**Not a host engine cut.** Pack 15 analog on free Workbench. Live Workgroup stays **2.73.13 W5**. analog ≠ native. certifiedClaim=false. Online tools only. Not a Community SKU. Downloads stay 2.73.13.

OGC next is a **v2** opaque cursor `{t,o,l,b,c,iat}` with analog FNV MAC when a token is set. Analog TTL 900s, skew 60s. Collection is bound. Tokened `offset>0` without a cursor is refused. Tokened v1 cursors are refused. Cursor bbox cannot be swapped. Token never copied onto `next`. RISK-10 stays OPEN — analog MAC is not HMAC-SHA / JWT / KMS.

Tachyon ISAM Open analog: GetEqual / GetNext / GetFirst require Open (status 3). Close without Open is status 3. Nested Begin is status 37. End or Abort without Begin is status 38. Empty key on GetEqual / Delete is status 6. Begin/End/Abort analog `durable=false` `mkde=false`. analog 128-byte pos-block is named.

Teaching desks: `/tools/ogc`, `/tools/isam-index`, `/tools/baseline`.

## What this analog hardens

1. OGC v2 cursor bind — TTL 900s, collection bind, bbox bind, token never on `next`. FNV analog MAC. HMAC-SHA / JWT / KMS leftover EXTERNAL.
2. Tachyon ISAM Open required — status 3 when the file is not open. Empty key is status 6.
3. Nested tx analog — nested Begin 37, End/Abort without Begin 38. Native MKDE leftover EXTERNAL.
4. SHOW POSBLOCK — analog 128-byte position block is named. Native pos-block leftover EXTERNAL.

## Honest leftover

HMAC-SHA / JWT / KMS · certified OGC · native requester · MKDE · TCP 1583 requester · engine 3.
