Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds read-only observation of effective PostgreSQL PITR settings without changing recovery state. It is mergeable with owner awareness that the API contract/public scope and caller-configured timeout requirements should be documented; these are bounded follow-up risks, not merge blockers.

Operator-facing
statement_timeout/ socket-timeout guidance and the public-versus-module-private API decision belong on the authoritative documentation surface, not in a competing documentation mutation from this source lane.Fresh #229/#316 ancestry corrects an older writer premise:
docs/canonical-documentation-authority@229f8d37833071ae8d6e84374f4007c44ac2fe59is an exact ancestor of active Draft #229 head93b76d2a06c4ce858738eebca278e1dbdbb5eb1d, and thedocs/canonical-documentation-current-main*refs resolve to historical protected-main ancestry. Those specifically named retained refs are therefore historical /SUPERSEDED_RETAINEDevidence for the current canonical-writer lease, not independent present-tense writers.That correction does not make the documentation lane writer-safe. #229 itself remains the active canonical-documentation writer, and a complete then-current documentation-path overlap inventory across all open PR and no-PR refs is still required before any canonical mutation. Preserve retained refs unchanged. Do not resolve the documentation review thread until the required contract is genuinely addressed through the authoritative docs lane and reconciled into this stack.

The prior CodeRabbit review was submitted against predecessor head
caf7325a11e4ec646115eaf530ca76104fbad6e6. Its three test-quality suggestions are represented by the test-only94d78bb...follow-up; predecessor COMMENTED review evidence is not approval and does not transfer.One separate documentation/public-surface inline thread remains current, non-outdated, valid, and unresolved. It requires README/CHANGELOG/relevant ADR/doctoring coverage of the fixed SQL observation, bounded assurances, timeout ownership, and public/module-private API decision. The thread remains open because those documentation requirements are not yet satisfied.
