GET /api/credshare/teams/:slug/vaults built its response in a loop, asking the database for a grant row and a secret count once per vault. libSQL is remote, so each of those is a network round trip, and the endpoint cost 2N+1 of them. On a team with 176 vaults that is 353 round trips and ~10.6s of server time. `logicsrc teams pull` resolves the vault id twice -- once planning the sync, once reading values -- so a pull of a single ten-key vault took ~24s, nearly all of it spent listing vaults the command does not want. Replaced with one SELECT carrying two correlated subqueries. Both are covered by existing primary keys (credshare_secrets is keyed (vault_id, name), credshare_vault_grants (vault_id, user_id)), so the per-vault work becomes an index probe inside the database instead of a round trip across the network. No schema or index change. Measured on a local libSQL seeded to match that team -- 176 vaults, 17 secrets each -- the endpoint goes from 355 round trips to 3, and returns identical rows. The response shape is unchanged: hasAccess is still a real boolean rather than the 0/1 SQLite hands back, and secretCount is still a number. Tests pin behaviour and cost separately. The behavioural cases pass against both the old loop and the new query, which is the point -- only the round-trip count changed. The regression guard asserts the query count for 3 vaults EQUALS the count for 30 rather than matching a magic number, so any future rewrite that reintroduces per-vault I/O fails no matter what the constant part costs. Against the old loop it reports 9 vs 63. Two sibling endpoints have the same shape -- /teams/:slug/members and /vaults/:id/grants both call publicKeyFor() per member. Neither is on the pull path and both scale with member count rather than vault count, so they are left alone here. Co-authored-by: Claude Opus 5 <noreply@anthropic.com> |
