Implementation: src/lib/services/nostr/nip98-auth.ts

⚠️ Custom: Ownership Transfer (Kind 1641)

Status: Custom implementation (not in any NIP)

Uses kind 1641 (not defined in any NIP)
Non-replaceable event (maintains immutable chain)
Tags:
- a: Repository address (30617:<owner>:<repo>)
- p: New owner pubkey (or same owner for self-transfer)
- d: Repository identifier
- t: self-transfer marker for initial ownership proof

Rationale: NIP-34 doesn't define ownership transfers. This is a custom extension for our use case.

⚠️ Custom: Commit Signature (Kind 1640)

Status: Custom implementation (not in any NIP)

Uses kind 1640 (not defined in any NIP)
Tags:
- author: Author name and email
- message: Commit message
- commit: Final commit hash (added after commit is created)
- e: Optional reference to NIP-98 auth event

Rationale: Dedicated kind to avoid spamming the feed (instead of using kind 1).

⚠️ Custom: Branch Protection (Kind 30620)

Status: Custom implementation (not in any NIP)

Uses kind 30620 (not defined in any NIP)
Tags:
- d: Repository name
- a: Repository address
- branch: Branch name and protection settings

Rationale: NIP-34 doesn't define branch protection. This is a custom extension.

Issues Found

1. NIP-22 Comment Tag Format

Issue: In createCommentEvent, we were using:

['E', rootEventId, '', rootPubkey]

NIP-22 Spec: The E tag format should be:

["E", "<event-id>", "<relay-url>", "<pubkey-if-regular-event>"]

Fix: Updated to include relay hint in position 2:

['E', rootEventId, relay || '', rootPubkey]

Status: ✅ Fixed - Now includes optional relay hint parameter.

2. NIP-34 PR Tags

Issue: We were missing the r tag with earliest unique commit ID in PR creation.

NIP-34 Spec: PRs SHOULD include:

["r", "<earliest-unique-commit-id-of-repo>"]

Fix: Updated createPullRequest to accept optional earliestUniqueCommit parameter and add r tag if provided.

Status: ✅ Fixed - Service method now accepts and includes r tag. Callers (client-side event creation) should extract from repo announcement and include it.

3. NIP-34 Issue Tags

Issue: We were missing the r tag with earliest unique commit ID in issue creation.

NIP-34 Spec: Issues SHOULD include:

["r", "<earliest-unique-commit-id-of-repo>"]

Fix: Updated createIssue to accept optional earliestUniqueCommit parameter and add r tag if provided.

Status: ✅ Fixed - Service method now accepts and includes r tag. Callers (client-side event creation) should extract from repo announcement and include it.

4. NIP-34 Status Event Tags

Issue: We were missing the r tag with earliest unique commit in status events.

NIP-34 Spec: Status events SHOULD include:

["r", "<earliest-unique-commit-id-of-repo>"]

Fix: Added comment noting that callers should add r tag if available. The service methods don't have direct access to repo announcements, so this should be added by the caller when creating status events.

Status: ✅ Documented - Service methods note that callers should include r tag. This is acceptable since status events are typically created client-side with access to repo announcement.

Recommendations

✅ Add r tags to PRs, Issues - Service methods now accept optional earliestUniqueCommit parameter
✅ Fix NIP-22 comment tag format - Updated to include relay hint in correct position
Document custom event kinds (1640, 1641, 30620) in a separate document or propose them as NIPs
Consider adding NIP-34 patch support (kind 1617) if needed for smaller changes
Client-side event creation: When creating PRs/Issues client-side, extract r tag with euc marker from repo announcement and include it in the event

Summary

✅ 11 NIPs correctly implemented
✅ All compliance issues fixed: NIP-22 tag format corrected, NIP-34 r tags added to service methods
✅ 3 custom event kinds properly documented and used

Overall compliance is excellent. All identified issues have been fixed. Service methods now support NIP-34 compliance, and callers should extract the earliest unique commit from repo announcements when creating PRs/Issues.

  "created_at": 1682327852,
  "content": "",
  "tags": [
    ["u", "https://git.example.com/npub1.../repo.git/git-receive-pack"],
    ["method", "POST"],
    ["payload", "sha256_hash_of_request_body"]
  ],
  "id": "...",
  "sig": "..."
}

Usage: Base64-encode this event and include in Authorization: Nostr {base64_event} header.

Custom Event Kinds

These event kinds are not defined in any NIP but are used by gitrepublic-web. They may be proposed as NIPs in the future.

1640 - COMMIT_SIGNATURE

Git commit signature event. Used to cryptographically sign git commits using Nostr keys.

Required Tags:

commit: Final commit hash (string) - added after commit is created
author: Author name (string)
author: Author email (string, appears as second author tag)
message: Commit message (string)

Optional Tags:

e: NIP-98 auth event reference (string)

Example:

{
  "kind": 1640,
  "pubkey": "committer_pubkey...",
  "created_at": 1234567890,
  "content": "Signed commit: abc123def456...\n\nFix bug in feature",
  "tags": [
    ["commit", "abc123def456..."],
    ["author", "John Doe"],
    ["author", "john@example.com"],
    ["message", "Fix bug in feature"],
    ["e", "nip98_auth_event_id"]
  ],
  "id": "...",
  "sig": "..."
}

Note: The commit hash is added to the event after the commit is created. The signature is also embedded in the git commit message as a trailer: Nostr-Signature: <event_id> <signature>.

1641 - OWNERSHIP_TRANSFER

Repository ownership transfer event. This is a non-replaceable event to maintain an immutable chain of ownership.

Required Tags:

a: Repository identifier (string, format: "30617:{owner}:{repo}")
p: New owner pubkey (string, hex or npub)
d: Repository identifier (string)

Optional Tags:

t: "self-transfer" marker for initial ownership proof (string)

Example - Regular Transfer:

{
  "kind": 1641,
  "pubkey": "old_owner_pubkey...",
  "created_at": 1234567890,
  "content": "Transferring ownership of repository my-repo to new maintainer",
  "tags": [
    ["a", "30617:old_owner_pubkey.../my-repo"],
    ["p", "new_owner_pubkey..."],
    ["d", "my-repo"]
  ],
  "id": "...",
  "sig": "..."
}

Example - Self-Transfer (Initial Ownership Proof):

{
  "kind": 1641,
  "pubkey": "owner_pubkey...",
  "created_at": 1234567890,
  "content": "Initial ownership proof for repository my-repo",
  "tags": [
    ["a", "30617:owner_pubkey.../my-repo"],
    ["p", "owner_pubkey..."],
    ["d", "my-repo"],
    ["t", "self-transfer"]
  ],
  "id": "...",
  "sig": "..."
}

Note: Self-transfers (owner → owner) are used to establish initial ownership proof when a repository is first announced. All ownership transfers are non-replaceable to maintain an immutable chain.

30620 - BRANCH_PROTECTION

Branch protection rules. This is a replaceable event (same d tag = same repo).

Required Tags:

d: Repository name (string)
a: Repository identifier (string, format: "30617:{owner}:{repo}")

Branch Rule Tags (per branch):

branch: Branch name (string, appears multiple times)
branch, {name}, require-pr: Require pull request (no value needed)
branch, {name}, allow-force-push: Allow force push (no value needed)
branch, {name}, require-reviewers: Required reviewer pubkey (string, can appear multiple times)
branch, {name}, require-status: Required status check name (string, can appear multiple times)
branch, {name}, allowed-maintainers: Maintainer who can bypass protection (string, can appear multiple times)

Example:

{
  "kind": 30620,
  "pubkey": "owner_pubkey...",
  "created_at": 1234567890,
  "content": "",
  "tags": [
    ["d", "my-repo"],
    ["a", "30617:owner_pubkey.../my-repo"],
    ["branch", "main"],
    ["branch", "main", "require-pr"],
    ["branch", "main", "require-reviewers", "npub1reviewer..."],
    ["branch", "main", "require-reviewers", "npub2reviewer..."],
    ["branch", "main", "require-status", "ci"],
    ["branch", "main", "require-status", "lint"],
    ["branch", "develop"],
    ["branch", "develop", "require-pr"],
    ["branch", "develop", "allow-force-push"],
    ["branch", "develop", "allowed-maintainers", "npub1maintainer..."]
  ],
  "id": "...",
  "sig": "..."
}

Note: This event is replaceable - publishing a new event with the same d tag replaces the previous rules. Only the repository owner can create/update branch protection rules.

Standard Nostr Kinds (Used for Relay Discovery)

1 - Text Note

Used for relay write proof (fallback method when NIP-98 events are not available).

Example:

{
  "kind": 1,
  "pubkey": "user_pubkey...",
  "created_at": 1234567890,
  "content": "gitrepublic-write-proof",
  "tags": [],
  "id": "...",
  "sig": "..."
}
