Summary

  • Reorganizes mkdocs.yml's nav into the standard pgedge-docs template.
  • Splits installation, configuration, and Lakekeeper/object-store setup into dedicated guides, and splits day-to-day usage by operating mode (Tiered, Decoupled, Standalone Partitioned), with a new Administration section for shared operational topics (caveats, vended credentials, supported column types, compaction). Distributed setup moves under Configuring ColdFront, and the reading-and-writing content is folded into the pages it describes.
  • Converts the Using ColdFront and Architecture Guides sections to real index.md pages so their nav headers open the intro content directly, with no duplicate nav entry.

Test plan

  • mkdocs build --strict passes with no warnings
  • Spot-check the nav in a local preview (mkdocs serve): Using ColdFront, Architecture Guides, and Administration all render and link correctly
  • Confirm README.md and docs/index.md still list every guide

Carry main's docs changes into the reorganized pages and apply the
review suggestions:

- supported_types.md: a cold-tier write that reads a PostgreSQL table
  stores a numeric NaN as 0 and an array renumbered from 1; add the
  query that checks a source table, and fix "is rejected" to "are".
- caveats.md and README.md: add the matching caveat, linked to
  Supported Column Types instead of the removed usage.md.
- architecture_decoupled.md: list every write that reads a PostgreSQL
  table through pglocal.
- usage_partitioner.md: registration refuses a column that is not the
  partition key.
- object_store.md: ADLS Gen2 needs hierarchical namespace.
- Keep usage.md deleted; drop the caveat paragraph that the merge placed
  in index.md, since caveats.md now carries it.

29-30: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Keep Lakekeeper bootstrap in one canonical location.

The Docker and bare-metal procedures in docs/configure_lakekeeper.md repeat the same bootstrap, warehouse, and namespace commands. This violates the one-home-per-topic requirement.

Keep the backend-specific warehouse instructions in docs/object_store.md, but link its common bootstrap step to docs/configure_lakekeeper.md. Use a dedicated bootstrap anchor so the link does not send users to the SeaweedFS-specific warehouse example.

Suggested fix
- Lakekeeper is now reachable at `localhost:8181` with no further setup.
- Bootstrap it, create the warehouse, and pre-create the Iceberg
- namespace:
-
- [duplicate Docker bootstrap, warehouse, and namespace commands]

1-119: 🎯 Functional Correctness

The strict-build request is not supported as a review finding. mkdocs.yml defines the navigation and link validation, but the supplied repository guidance does not require mkdocs build --strict or a reported validation result. The unchecked test-plan item does not establish a failure or a skipped mandatory check. No actionable defect remains.

docs/architecture_guides/index.md: 1

10-11: 📐 Maintainability & Code Quality

No actionable documentation finding is established. The repository requires mkdocs build --strict to pass, but the absence of a reported result does not show that the build was skipped or failed. The unchecked test-plan item does not establish either condition.

37-37: 📐 Maintainability & Code Quality

The changed links do not show a documentation defect. The repository already runs mkdocs build --strict through its CI matrix, but an unchecked test-plan item does not prove that the check failed or was skipped. This validation request is not actionable without a reported build failure.

194-196: 🗄️ Data Integrity & Integration

The concern is refuted. release_iceberg_table() calls _unregister_iceberg() after rejecting tiered registrations. That helper deletes the registry row, vector configuration and centroids, drops the wrapper view, and performs no Iceberg I/O. The Iceberg table therefore remains in the catalog with its rows.

🟡 Minor · Recover WID after duplicate warehouse creation. · object_store.md:395-408

docs/object_store.md:395-408
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Recover WID after duplicate warehouse creation.

If namespace creation fails and an operator reruns any backend setup, the duplicate warehouse response leaves WID empty. The shared namespace step then skips namespace creation. Add duplicate-response recovery to the backend setup flow, using the existing ci/lib.sh pattern to list warehouses and recover the existing ID.

🟠 Major · Bind the Compose catalog to loopback. · configure_lakekeeper.md:112-127

docs/configure_lakekeeper.md:112-127
🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Bind the Compose catalog to loopback.

The Compose command publishes Lakekeeper on all host interfaces by default. Compose sets no bind address or authorization backend, so remote clients can reach the unauthenticated catalog and management APIs when the host is network-reachable. The guide’s 127.0.0.1 setting applies only to the separate bare-metal configuration.

Suggested fix
- docker compose --profile local-store up -d --build
+ COLDFRONT_LK_PORT=127.0.0.1:8181 \
+   docker compose --profile local-store up -d --build

State that this setup is for same-host clients only. Require authentication, enforcing authorization, and firewall restrictions before exposing the Compose port to remote clients.

This is separate from the local bootstrap requests: those requests intentionally use no bearer token. The risk is that the published unauthenticated listener is reachable beyond the local host.
