feat: sponsor leaderboard, daily report and tier roles - #803
Conversation
The leaderboard was fed by hand with /add-points. Pull the numbers from the funding platforms instead, post them daily, and hand out roles. - SponsorService reads GitHub Sponsors (GraphQL) and Patreon, keeping state in sponsors.json next to the existing contribution.json - SponsorSyncService posts the ranking once a day and reconciles the Supporter / Gold / Legendary / Top Sponsor roles - SponsorModule adds /sponsors, /sponsor-sync and the account link commands Private sponsors are listed as Anonymous with their amount. Platforms whose credentials are unset are skipped, so this is inert until configured. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
WalkthroughThe pull request adds GitHub and Patreon sponsor aggregation, S3-backed state, Discord role synchronization, leaderboard reporting, sponsor management commands, startup wiring, tests, and README documentation. ChangesSponsor leaderboard

LastReportUtc is not assigned or persisted before guild lookup, role

state only after successful message delivery, preserving retries when any
Discord operation fails.
- Around line 134-139: Update the role-synchronization loop in
SponsorSyncService so it evaluates every linked guild member or member currently
bearing managed roles, not only entries in state.Snapshot. Treat missing links
and sponsors absent from the current snapshot as having no desired managed

roles granted by current sponsor entries.

Make state updates atomic.
SaveStateAsync replaces the complete SponsorState. The scheduled synchronization and admin commands perform independent load-modify-save sequences. If /link-sponsor saves while RunAsync holds an older state, the later write can remove the new link. The reverse order can discard a refreshed snapshot or report timestamp.
Serialize the complete update transaction in one service method. If multiple bot instances can run, also use an S3 conditional write with an object version or ETag.

Review found the snapshot treated historical sponsorships as current. - read isActive, zero the monthly amount when a sponsorship has ended, and freeze lifetime totals in state instead of recomputing them from the start date forever - reconcile roles every tick, publish once a day, and record the report only after the message actually goes out - strip managed roles from members who no longer qualify, including after an unlink or a sponsor leaving the snapshot - page through both APIs, and serialise load-modify-save so a link command and the timer cannot clobber each other Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Do not persist a partial sponsor snapshot after an API failure.
These branches return an empty or partially paginated list. SponsorSyncService.RunAsync treats that list as authoritative and replaces current.Snapshot. A first-page failure removes all sponsors from that platform. A later-page failure removes sponsors from the omitted pages and can remove their Discord roles.
Throw after logging the failure. FetchAsync runs before MutateAsync, so this preserves the previous S3 state and role assignments for the next retry.

site:docs.github.com GitHub global node ID stable username rename integrations GraphQL
💡 Result:
GitHub global node IDs are designed to be immutable and stable, meaning they remain constant for a specific object (such as a user or repository) even if that object’s name or login is changed [1][2]. When a user renames their account or a repository is renamed, the global node ID associated with that account or repository does not change, which makes it the recommended identifier for persisting references in integrations [1]. For developers building integrations, relying on these global node IDs is a best practice for maintaining stability across API versions and account lifecycle events [1][3]. Because the node ID is permanent, it ensures that your integration can continue to identify and reference the correct object even when mutable properties like a username or repository name are updated [1]. While web-based redirects exist for repositories and some user-related content after a rename, these are primarily for browsers and Git operations [4][5]. For API-based integrations, using the global node ID is superior because it avoids dependency on these redirection mechanisms [1]. You should store these node IDs as opaque strings and treat them as the canonical reference for the entity within the GitHub API ecosystem [2]. Note that you should treat these IDs as opaque; you should not attempt to parse or extract information from them, as the internal format of these IDs can change [2].

Use the stable GitHub node ID for SponsorEntry.Id.
FetchGitHubAsync currently requests and persists only login as the key for SponsorState.Links and SponsorState.Lifetime. A login rename can orphan the existing link and lifetime record, then create a second record under the new key. Request sponsorEntity.id and use it as the canonical identity. Resolve login aliases to that key, and migrate existing github:<login> keys.

Patreon API v2 pagination page[cursor] cursors next official documentation
💡 Result:
Patreon's API v2 uses cursor-based pagination to handle large datasets [1][2]. To retrieve paginated results, you should use the pagination cursors provided in the API response metadata [1][2]. How to Implement Pagination: 1. Check for the Next Cursor: In the response JSON, look for the meta object, which contains a pagination section with a cursors object [1][2]. The 'next' field provides the cursor string for the subsequent page [1][2]. Example path in response: meta -> pagination -> cursors -> next [1][2] 2. Using the Cursor: You can paginate by including the page[cursor] parameter in your next API request [2]. Example URL structure: GET /api/oauth2/v2/campaigns/{campaign_id}/members?page[cursor]={next_cursor_value} [2] 3. Using 'links': Alternatively, the API response often includes a 'links' object at the root level, which provides a 'next' URL containing the fully constructed request for the next page [2]. Following this 'next' URL is often the simplest way to navigate through all pages [2]. 4. Setting Page Size: You can control the number of results per page by adding the page[count] parameter to your request (e.g., page[count]=100) [3][2]. 5. Termination Condition: Continue making requests using the 'next' cursor or 'next' link until the API response no longer includes a 'next' cursor or link [1][2]. Authoritative documentation is available at the official Patreon API reference [1]. For developers using official SDKs, such as the Python client, utility methods like extract_cursor are often provided to simplify extracting these values from responses [4][5].

Build the next Patreon URL with page[cursor].
NextPatreonPage returns the opaque meta.pagination.cursors.next value, but FetchPatreonAsync assigns it directly to url. The next request must keep the campaign members URL and add the escaped cursor as page[cursor]; otherwise later pages are not fetched and their sponsors are omitted.
