Summary

Restricts the bounty stats aggregates to repos an anonymous caller can list, so private-repo bounty activity and agent earnings stop leaking through GET /api/v1/bounties/stats and GET /api/v1/agents/{did}/bounties.

Motivation & context

Both endpoints ran unfiltered aggregates over every bounty. An anonymous caller could watch the global open/claimed/completed counts move, read the leaderboard, and read per-agent earnings derived from private repos.

Continues #495 by @Mystic-commits (their commit is kept as authored). Supersedes #483, which fixes the same issue with a per-request scan of the whole bounties table.

Closes #477

• Refactor (no behavior change)
• Breaking or protocol change (issue required first)

What changed

Crate touched: gitlawb-node.

• api/bounties.rs: visible_repo_pairs() resolves the anonymously-listable (owner, name) set once per request (deduped repos plus their visibility rules, filtered by listable_at_root, the same shape as /stats in server.rs). A database error collapses to an empty set, so counts go to zero rather than leak.
• db/mod.rs: visibility-scoped counterparts of the three aggregates, filtering on that set in SQL, with owner and claimant keys normalized so did:key: and bare-key forms match. The unfiltered originals are removed.
• test_support.rs: deny-path tests for both endpoints, a root-rule-overrides-is_public case, and a mirror-row case (a mirror whose canonical twin is private is hidden; a mirror-only repo counts, as it does for authorize_repo_read and /stats).
• Two follow-up commits on top of the contributor's: cargo fmt, and a comment recording why mirror rows are handled as above.

How a reviewer can verify

cargo test -p gitlawb-node --bin gitlawb-node bounty_stats
cargo fmt --all -- --check
cargo clippy -p gitlawb-node --all-targets -- -D warnings

The mirror-row test fails if the visibility rules are ignored and fails if mirror-only repos are dropped; I checked both by injecting each change.

Before you request review

• Scope is one logical change; no unrelated churn
• cargo test --workspace passes locally
• New behavior is covered by tests (required for fixes)
• cargo fmt --all and cargo clippy --workspace --all-targets -- -D warnings are clean
• Commit titles use Conventional Commits (feat(...), fix(...), docs(...))
• Docs / .env.example updated if behavior or config changed (or N/A)
• Checked existing PRs so this isn't a duplicate

Protocol & signing impact

• Touches DID / did:key, Ed25519 / RFC 9421 signatures, UCAN, ref certs, or P2P wire formats
• Discussed in an issue before implementation
• Backward-compatible with existing nodes and previously signed history

Notes for reviewers

• On unfixed main the per-agent and leaderboard aggregates also fail to decode: SUM(amount) comes back as NUMERIC and r.get::<i64, _>("total") panics once a completed bounty exists. The new queries cast the sum to BIGINT. On main, three of the four new tests panic on that decode before they reach their assertions, and the mirror-row test shows the leak itself (anonymous open count 2, expected 1).

• Every caller, signed or not, gets the anonymous-scoped aggregates. A signed owner does not see their own private bounties in the totals; the per-repo and per-bounty reads remain gated as before.

• Bounties on repos that are not in the local deduped set (quarantined or absent) drop out of the aggregates.

• I ran the bounty tests, fmt and clippy for gitlawb-node on the merged tree, not the whole workspace.

Summary by CodeRabbit

• Bug Fixes
  • Bounty counts, leaderboards, and agent earnings include only bounties from repositories visible to anonymous readers. Private repositories and repositories hidden by visibility rules are excluded, including when accessed through a mirror.
  • Agent statistics correctly combine claimant identities recorded with or without the did:key: prefix.
  • Errors encountered while loading repository visibility or bounty statistics are reported as server errors instead of appearing as zero counts or an empty leaderboard.

Walkthrough

Bounty status counts, leaderboards, and per-agent statistics now include only bounties from anonymously listable repositories. Database errors from repository visibility loading and aggregate queries propagate from the endpoints.

Changes: Bounty statistics visibility

Layer / File(s)	Summary
Visible-repository database aggregates crates/gitlawb-node/src/db/mod.rs	Aggregate query methods now filter by visible repository pairs. Owner and claimant identifiers use did:key: normalization.
API visibility filtering and validation crates/gitlawb-node/src/api/bounties.rs, crates/gitlawb-node/src/test_support.rs	The API selects repositories that pass root-level anonymous listability checks before querying aggregates. Errors propagate instead of returning default counts. Integration tests cover private repositories, identifier forms, database failures, mirrors, and root visibility rules.

Merge readiness

• CI: Required PR Checks (test (stable), test (beta), fmt+clippy, release build, Docker smoke, MSRV, cargo audit) were green at review completion. CodeQL (swift) and CodeRabbit were still pending; confirm those finish acceptably before merge if your policy treats them as blocking.
• Author checklist: The PR body leaves cargo test --workspace unchecked while noting scoped local runs for gitlawb-node only. That is reasonable for this crate-local fix but worth matching against maintainer expectations before merge.
• Branch freshness: PR base equals current main (a23c81d); no rebase conflict signal from this review.

Findings

🟢 Thanks for the contribution. I do not see any actionable issues from my review.

The change correctly mirrors the /stats repo-count visibility seam (list_all_repos_deduped, batch visibility rules, listable_at_root with anonymous caller, fail-closed DB errors) and applies it to bounty status counts, the leaderboard, and per-agent earnings. Deny-path coverage includes private vs public repos, root-rule override of is_public, mirror canonical-twin vs mirror-only behavior, and real claim→submit→approve persistence for completed bounties. Local validation: cargo test -p gitlawb-node --bin gitlawb-node bounty_stats — 4/4 passed in the review runtime.

Intentional behavior (not a defect): signed and anonymous callers receive the same anonymously scoped aggregates, matching server::stats() and the PR’s stated #104 pattern; per-repo bounty reads remain gated separately.

Needs maintainer decision

None.

Bound work on the anonymous aggregate routes.

Each request loads all deduplicated repos and their rules before running the aggregates. On a large node, concurrent anonymous requests can repeat this work and reduce database throughput.

Bound or cache the visibility lookup with safe invalidation, and add a request-rate limit. Preserve complete visibility decisions and fail closed on incomplete lookups. Check peak inventory and request rates to size the controls.

Bound work on the anonymous aggregate routes.

Leaving this one as is for now. The cost is real: each anonymous call loads the deduplicated repos and their rules before aggregating. The /stats route in server.rs does the same per-request load, so it is not specific to this change, and bounding or caching it needs an invalidation design and a rate-limit policy across the anonymous read surface. That fits a separate change better than this fix. Happy to open a follow-up for it.

[coderabbitai]

@beardthelion Agreed. A separate change can address the visibility lookup and rate-limit policy across anonymous read routes.

Would you like me to open a follow-up issue?

Merge readiness

• Head moved after prior approval: GitHub shows APPROVED from jatmn on commit 5ed5b203 (mirror test + docs). Current head 680f468a adds claimant-index-friendly SQL (73cb017) and propagates visibility/aggregate DB errors instead of zero counts (680f468). Worth a quick maintainer re-read of those two commits even if the visibility fix itself was already accepted.
• CI: At review time, test (stable), fmt+clippy, release build, Windows (non-blocking), MSRV, cargo audit, and CodeRabbit were green. test (beta), CodeQL Rust/Swift, and Docker smoke were still pending—confirm per repo policy before merge.
• PR description drift: The opening commit message and parts of the PR body still describe visibility DB failures collapsing to an empty set (zero counts). Current code and bounty_stats_db_failure_is_not_reported_as_zero require 5xx instead. Cosmetic doc fix only; CodeRabbit pre-merge check already flagged this.
• Checklist: cargo test --workspace remains unchecked; author scoped runs to gitlawb-node bounty tests—aligned with crate-local change.
• Branch base: PR base matches captured main (a23c81d); no rebase conflict signal from this review.

Findings

🟢 Thanks for the contribution. I do not see any actionable issues from my review.

The change implements issue #477 by mirroring the /stats visibility seam: deduped repos, batched rules, listable_at_root(..., None), normalized (owner,name) filtering in SQL, and removal of the old unfiltered aggregates. Deny-path tests cover private vs public repos, root-rule override of is_public, mirror canonical-twin vs mirror-only behavior, claimant did:key: vs bare-key matching, and DB-down behavior (must not return HTTP 200 with zeros). Follow-up commits on head address CodeRabbit’s indexed-claimant concern and error propagation without widening scope.

Intentional behavior (not a defect): Signed and anonymous callers both receive anonymously scoped aggregates, matching server::stats() and the PR’s stated #104 pattern; per-repo bounty reads stay gated elsewhere. Bounty endpoints propagate visibility/aggregate DB errors as 5xx while /stats still collapses repo-count errors to zero—that divergence is new on the bounty routes only and is covered by this PR’s test; changing /stats is out of scope here.

Needs maintainer decision

None.
