How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🔵 Low · up to The change blocks credential-bearing PostgreSQL DSNs from process arguments while preserving credential-free selectors. The PR is otherwise mergeable with explicit owner awareness that the updated rollback contract still needs the required README, operator-guide, architecture, ADR, and CHANGELOG documentation.

Control-plane evidence for exact current head

Security boundary
Closes the package-owned argv disclosure gap tracked in #117 without changing database-target authority. The CLI continues to accept explicit credential-free libpq selectors through
--dsn, but rejects password/private-key-bearing URI/conninfo before bootstrap/database/provider acquisition and without reflecting rejected content.Test-first implementation
The branch preserves RED regressions for credential-bearing PostgreSQL URI/keyword conninfo and malformed conninfo, then implements the narrow boundary with Psycopg/libpq
conninfo_to_dict()rather than ad-hoc DSN rewriting. It documents the transition to standard libpq authentication mechanisms outside process argv.Current exact integration evidence
Freshly revalidated after protected streaming PR #177 integrated:
main:0052c00f31b404ef8b328f3175e3fe1245afc7c2;035d45e36879dd9fd723b84d2cfd85383d7ee1fd;pg_llm_batch/cli.py,tests/test_cli_dsn_argv_security.py, anddocs/doctoring/bootstrap-dsn-precedence.md;The exact head was refreshed by a non-destructive merge of the protected #177 result; no stale/predecessor evidence transfers across that base movement.
Merge boundary
Merge only when this unchanged exact head satisfies every live required workflow, Python 3.10/3.12/3.14, exact 100% owned production statement/branch coverage and public docstrings, security/SAST/package/provenance/release acceptance, zero valid unresolved findings, live-base mergeability, and every approval requirement actually imposed by the live ruleset. Do not treat queued, pending, skipped, absent, neutral, stale-head/base, predecessor, status-only, synthetic, author-only, rate-limited, infrastructure-only, or failed evidence as success.
