State model

V2 state is address-native.

Core selectors

• account bookkeeping is keyed by owner_address
• project ownership is stored as owner_address
• collaborators use target_owner_address
• links and reactions use owner_address and reverse address-native indexes
• commit metadata uses author_address

Account defaults

If an account row is absent, the canonical default view is:

• key_count = 0
• project_count = 0
• storage_units = 0
• custody_nonce = 0
• created_at = 0

Merkle scope

The canonical merkleized prefixes are 0x03 through 0x17 inclusive, plus 0x1A through 0x1C.

0x02, 0x18, and 0x19 remain persisted but are not part of state_root.

Merge request state

Three prefix families support merge requests:

• 0x1A stores the immediate fork parent for each fork project, independent of prunable project rows, so merge-request lineage validation survives project pruning
• 0x1B and 0x1C are a forward/reverse pair — for every forward entry, a matching reverse entry must exist, and vice versa
• ProjectState includes merge_request_count, which tracks the number of active merge requests targeting the project
• 0x1A, 0x1B, and 0x1C are all queryable and merkleized

Removed state concepts

V2 state does not include:

• registry allocation metadata
• ownership transfer markers
• signer-authorization event markers
• storage-rent event markers
• relay checkpoint provenance
