A newly added REST failure path can return database error details to signed callers; the comparable GraphQL path masks database errors.

Verified the gate end to end on this head. Built the tree, ran the create_task suite green, then removed the new check in a scratch tree and watched the stranger case go red (201 instead of 403); did the same for the quarantine arm and for the GraphQL copy. Both surfaces deny a non-owner naming a hosted repo and keep unknown, quarantined, and absent ids accepted, matching the contract in the comments.
One scope note, not an ask: the read side that gives this teeth (task_visible and friends) lives in #464, still open. I checked that diff: it resolves task.repo_id against repos.id, the same keyspace get_repo_by_id matches, and it dead-ends slash-form mirror ids, so this gate lands cleanly when that ships. On today's main a planted task's repo_id is still just a label.
Findings
-
[P2] Return an opaque body from the new repo-lookup failure arms
crates/gitlawb-node/src/api/tasks.rs:119
Both newmap_errarms serializee.to_string()into the 500 JSON body. The GraphQL half of this same PR opaques the identical failures throughgraphql_db_err, and the repo already has the fixed envelope for this:{"error":"db_error","message":DB_ERROR_MESSAGE}(error.rs, used byapi/events.rs). The file's older arms do the same thing, so this ask covers only the two lines this PR adds: log the real error withtracingand return the fixed shape. -
[P3] Assert the denied write did not persist
crates/gitlawb-node/src/test_support.rs:633
I moved the gate belowdb.create_taskand every test stayed green while the stranger's task landed in the table under the victim's repo id. A denial that still writes is exactly what this change exists to prevent. After the 403 arm, read the task store back and assert no row carries thatrepo_id; same for the GraphQL test. -
[P3] Pin the quarantined and unknown-id arms on the GraphQL copy too
crates/gitlawb-node/src/graphql/mutation.rs:54
The gate is a second copy, not a shared helper. I dropped!quarantinedon the GraphQL side and all four tests stayed green, so that copy can regress silently. Either cover the quarantined/unknown arms in the GraphQL test or factor the check into one helper both surfaces call. -
[P3] Correct the no-existence-oracle comment
crates/gitlawb-node/src/api/tasks.rs:109
The comment claims "no existence oracle either way", but the 403-vs-201 split between a hosted non-quarantined repo id and an unknown id is itself an oracle: a stranger holding a private repo's id learns it is hosted here. The behavior is defensible (denying foreign repos requires distinguishing them, and repo ids already leak via the open task list on this base); the comment should describe the split honestly rather than claim it away.
Not an ask, recorded only: a task filed under a quarantined repo id still stores that id verbatim, so if a quarantined row is ever released the label binds to a live repo without ever passing the owner check. No release path ships today (set_repo_quarantine has only test callers), so this is forward-looking rather than a defect.
One process note, not a finding: the cargo audit failure is advisories against lru, core2, and spin in the shared lockfile, unrelated to this diff, which touches no Cargo files. Nothing for you to do there.
Summary
create_taskno longer binds a caller-suppliedrepo_idverbatim. Arepo_idnaming a hosted, non-quarantined repo is accepted only from that repo's owner; anything else keeps the previous behavior.Motivation & context
Closes #496
Any signed caller could plant a task — payload and UCAN included — under a repo id it does not own. Once task reads are repo-gated (#464), such an injected task surfaces exactly to that repo's readers and is claimable by the named assignee, so the write side has to verify ownership of the supplied
repo_id.Kind of change
What changed
gitlawb-node(api/tasks.rs,graphql/mutation.rs): RESTPOST /api/v1/tasksand GraphQLcreateTaskresolve a suppliedrepo_idviaget_repo_by_idand requirerequire_repo_owner(403 otherwise). Quarantined ids are treated as unknown — 403ing them would confirm a real id — and unknown ids stay oracle-free opaque labels (unscoped under the Unauthenticated task reads expose agent-task UCAN tokens, payloads, and private-repo IDs on both GraphQL and REST #268/fix(node)!: Gate agent-task reads behind visibility rules #464 read contract, which fails closed on ids that resolve to no hosted repo). Repo-less creation is unaffected.gitlawb-node(api/mod.rs): pinned the new gate with arequire_repo_owner(row forcreate_taskin theauthz_guarddrift test, alongside the existing signer-binding row.How a reviewer can verify

assignee_didis intentionally still taken verbatim — it is the delegation target and is bound to the signer at claim time on both surfaces. The gate choice is owner-only rather than read-gated (unlikecreate_bounty): tasks are executable work orders carrying payload+UCAN, and a read gate would leave injection into public repos wide open.Summary by CodeRabbit
