Conflicts

File	Resolution
crates/buzz-core/src/kind.rs	Kept upstream's KIND_PROJECT = 30621 and kept the fork-local KIND_STARKNET_WALLET_BINDING = 30900 block in its reserved position after the NIP-34 git kinds. Both constants are present.
crates/buzz-relay/src/handlers/ingest.rs	Merged both import lists — upstream's KIND_PROJECT added alongside the fork's KIND_STARKNET_WALLET_BINDING.
desktop/src-tauri/tauri.conf.json	Kept fork's productName: "BitcoinMarkets", took upstream's version: "0.5.3".

Needs a human look

• kind.rs / ingest.rs: The new KIND_PROJECT = 30621 (NIP-MP multi-repo projects) has been integrated. Verify that the fork's KIND_STARKNET_WALLET_BINDING = 30900 ingest branch still handles attestation correctly alongside the new project kind, since both are now in the same import list.
• tauri.conf.json: Version bumped to 0.5.3. The desktop release version in CHANGELOG.md and Info.plist should match; no further conflicts seen there.
• release.yml: Upstream fix(release): require exact-head approval for desktop tags block/buzz#3973 and fix(release): preserve main in desktop PR body block/buzz#3979 touch release CI. This fork carries patches to release.yml — verify the resolved file still has the fork's RELEASE_REPO guard and github.repository-derived variables intact (those files merged cleanly, but worth a read).

Note: This PR was resolved by the agentic sync stage. The merge commit's second parent is dropped when gh-aw applies it as a patch, so the merge base does not advance. Re-merge upstream by hand after merging (git merge upstream/main on main) to keep the counter current.

Closing in favour of a hand-merged branch that preserves upstream ancestry.

Two independent problems with this PR:

1. Flattened merge. The head commit has 1 parent, not 2, and the branch does not contain upstream/main. Simulating the merge locally confirms that landing this leaves git rev-list --count upstream/main ^main at 10 — the merge base never advances, so the fork keeps reporting behind and the next sync re-resolves the same conflicts from the same stale base. This is the gh-aw patch-flattening failure documented in AGENTS.md.

2. Red CI. Detect Changed Paths exits 126 — scripts/test-desktop-release-authorization.sh: Permission denied. Two new upstream scripts arrived with mode 100644 instead of upstream's 100755 (test-desktop-release-authorization.sh, verify-desktop-release-authorization.sh), so test-release-ref-contract.sh cannot execute them. They show as zero-line diffs.

Replacement branch has real two-parent ancestry, correct file modes, and merges the remaining upstream commits cleanly.
