It does not seed any public bounty for the agent, so an implementation that always returns zero for any anonymous caller (an over-denial regression, not just the intended visibility filter) would pass this test without being caught.Add a public-repo completed bounty for the same agent, and assert that its amount and count ARE reflected in the response.

Match earnings decoding to PostgreSQL’s aggregate type.
bounties.amount is BIGINT, so PostgreSQL returns NUMERIC for SUM(amount). Both visible queries decode that result with Row::get::<i64>, which can panic when the visibility list is non-empty. Cast the aggregate to BIGINT with explicit overflow handling, or decode it as NUMERIC and convert it safely. The existing unfiltered methods use the same unsafe decoding pattern.
The integration test calls /api/v1/bounties/stats and asserts total_earned == 300, so it exercises the visible leaderboard decode path.

Built this head and ran the new tests against a local Postgres. Both fail, and not because the filter is wrong: the seed path cannot create the state the assertions measure. With claimant_did persisted, both tests pass through the real router, and removing the visibility predicate makes them fail again, so the implementation is verified working and the tests will be load-bearing once the seeding is fixed. The in-SQL filter is also the right shape here: the visibility decision sits inside the query, so the leaderboard LIMIT cannot under-serve after filtering, and visible_repo_pairs reuses the same anonymous-listable evaluation as /api/v1/stats.
Findings
-
[P1] Seed claimant state through a path that persists it
crates/gitlawb-node/src/test_support.rs:14984
Both new tests fail at this head:bounty_stats_filters_private_repos_for_anonon the leaderboard assertion andagent_bounty_stats_filters_private_repos_for_anononcompleted_bounties.create_bounty's INSERT (crates/gitlawb-node/src/db/mod.rs:4389) binds only ten columns and dropsclaimant_didandcompleted_at, so the seeded completed bounties land with a NULL claimant and the claimant-filtered queries legitimately return zero. I confirmed the failure is the seed, not the fix: patching the tests to UPDATEclaimant_didaftercreate_bountyturns both green, and removing the filter then turns them red again. Drive the rows through the real claim/approve path, or write them with SQL directly. While you are in there, add a case where a repo's visibility is decided by a root rule rather thanis_publicalone, since that half of the gate is currently unexercised. -
[P2] Delete the orphaned unfiltered aggregate methods
crates/gitlawb-node/src/db/mod.rs:4531
count_bounties_by_status,agent_bounty_stats, andbounty_leaderboardhave no callers left on this head, andcargo clippy --locked --workspace --all-targets -- -D warningsfails on dead_code, the same gate CI runs. Deleting them also retires the unscoped query surface this PR exists to close. -
[P2] Normalize the owner key on both sides of the pair match
crates/gitlawb-node/src/db/mod.rs:4589
b.repo_owner = v.ois a byte comparison across two normalization domains.create_bountystoresrepo_ownerverbatim from the URL segment (crates/gitlawb-node/src/api/bounties.rs:89), whileget_repoaccepts bothdid:key:and bare-key spellings, so a bounty created through the bare-form URL, or against a mirror-only group whose stored owner is the bare form, drops out of every aggregate even though its repo is anonymously listable. Verified against a live Postgres: byte-exact matching misses the skewed row; emittingnormalize_owner_key(&r.owner_did)pairs and applying the same CASE tob.repo_owner(the patternPROFILE_DID_CASE_SQLalready uses) counts both. The same shape applies toclaimant_did = $1at the agent endpoint, since the{did}param arrives verbatim too. -
[P3] Fix the
visible_repo_pairsdocstring
crates/gitlawb-node/src/api/bounties.rs:467
"The auth extractor is accepted but currently unused" describes a parameter that does not exist: neither handler takesExtension<AuthenticatedDid>and the helper has no caller argument. State it plainly instead: every caller, signed or not, currently receives the anonymous-scoped aggregates.
One process note, not a finding: the "How a reviewer can verify" commands name --test test_support, which is not a test target (the tests live in the test_support module of the gitlawb-node bin). cargo test -p gitlawb-node --bin gitlawb-node filters_private_repos_for_anon is the working invocation.
Not an ask, recorded only: each anonymous stats call now runs two whole-table reads before the aggregates, and the read group carries no rate limiter. That matches the shape /api/v1/stats already exposes, so I am not holding the PR on it, but a bound or short-TTL cache is worth a follow-up. Same for the fail-closed collapse: a DB error returns a well-formed all-zero 200, consistent with the existing endpoint but indistinguishable from an empty node.

This is the stronger of the two #477 fixes. The batch-load-once with in-memory listable_at_root evaluation and aggregation delegated to Postgres avoids the per-request table walk and N+1 authorize_repo_read pattern, errors fail closed to an empty visible set, and the deny-probe tests cover the anonymous caller case directly. One scoping note: aggregates are anonymous-listable for everyone rather than per-caller (an authenticated owner does not see their own private-repo counts in the aggregate), which matches the #104 canonical pattern and is fine, but worth stating in the description so the semantics are deliberate.

Group leaderboard earnings by normalized claimant DID.
If completed bounties store both did:key:z… and z… for one claimant, GROUP BY claimant_did creates two leaderboard entries. agent_bounty_stats_visible combines those forms, so the endpoints report different earnings and the top-ten limit can exclude an agent. Group by the same normalized identity and select one stable DID for the response.

bounty_stats and agent_bounty_stats ran unfiltered aggregates over all bounties, leaking private-repo bounty activity to anonymous callers. Mirror the stats() pattern from server.rs (Twigpine#104): 1. Batch-load all deduped repos + visibility rules (2 SQL round-trips) 2. Filter to listable_at_root(rules, is_public, owner_did, None) 3. Pass visible (owner, name) pairs into SQL aggregates via EXISTS/unnest with owner key normalization on both sides (BOUNTY_OWNER_CASE_SQL). 4. Normalize claimant DID in agent_bounty_stats_visible and group by normalized claimant in bounty_leaderboard_visible (BOUNTY_CLAIMANT_CASE_SQL). 5. Remove orphaned unfiltered aggregate methods to pass dead_code lints. 6. In tests, seed completed bounty claimant state via the real claim/approve path, and verify root-rule-decided visibility overrides. Aggregates are intentionally anonymous-scoped for all callers (matching the Twigpine#104 stats pattern). Fail-closed: DB errors collapse the visible set to empty, so all counts return 0 — an under-count never leaks existence. Fixes Twigpine#477

Re-reviewed 7afd30bc after the fixes from my earlier round. I checked out the head in a worktree and ran cargo test -p gitlawb-node --bin gitlawb-node filters_private_repos_for_anon, bounty_stats_root_rule_overrides_is_public, and normalize_owner_key_matches_sql_case against local Postgres; all passed. visible_repo_pairs follows the same deduped-repo, batched-rules, listable_at_root seam as /api/v1/stats, the SQL aggregates normalize repo_owner and claimant_did on both sides of the match, and the old unfiltered DB methods are gone.
Not an ask, recorded only: mirror-only rows in the deduped set and the per-request full repo/rule scan share the same follow-up class as /api/v1/stats (#104); I am not holding #477 on them.
