Problem

revision counts supersessions within an issuance lineage, and it is the number
vaultuse.v1.CreateResult.version reports to a caller. It is a uint64 that starts at 0 at
genesis.

The private side is pinning its issuance version surface to 1-based uint32, with 0
reserved as the "serve the latest" sentinel on every lane that selects a version. That
settles the offset question the vault interface notes left open, where a 0-based custody
version had to be translated against 1-based KV-v2 versions on every read and write.
revision has to move with it: if genesis stays 0, CreateResult.version reports 0 for a
brand-new record, which is the sentinel rather than a version.

Fix

Genesis is revision 1, and the field narrows to uint32.

Wire-compatible in both directions: uint32 and uint64 are both varint on the same field
number, so no reserved range and no renumbering. Only the value at genesis changes.

Impact

Consumers that treated revision 0 as "the first version" now see 1. Nothing reads the field
as a presence signal today.

revision is one of the two counters that walk an issuance lineage forward,
and it is the number CreateResult.version reports. Genesis moves from 0 to
1 so that 0 is free as the "serve the latest" sentinel every read lane
accepts, and the width drops to uint32 to match the rest of the issuance
version surface.

Wire-compatible: both are varint on the same field number.

Walkthrough

The protobuf revision field changes from uint64 to uint32. Genesis revisions now start at 1, while revision 0 is reserved as the read-lane latest sentinel.

Changes

Revision Contract

Layer / File(s) Summary
Update revision field semantics
proto/splitsecure/teamresource/v1/base_resource_attributes.proto
BaseResourceAttributes.revision changes to uint32. Genesis revisions use 1; superseding revisions continue to increment the predecessor revision; 0 represents the latest sentinel.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🟠 High · up to f0864

The public schema change fails required compatibility validation. Retain uint64 or use the approved versioning and migration path before merging.
