High-Level Assessment

Explicit patch-level pins are appropriate for a supported release branch because they keep the runtime, installer, and catalog deterministic and compatible. Floating 1.9 tags were considered but would allow unreviewed patch changes to alter local environments.

1. Users can still select the old floating image 🐞 Bug ⚙ Maintainability

Description

The Compose default now uses quay.io/rhdh-community/rhdh:1.9.8, but the documented override and
container-image guide still tell users to use quay.io/rhdh-community/rhdh:1.9. Following those
instructions explicitly selects the unpinned image and undermines the release branch's version pin.

Evidence

The changed Compose default is quay.io/rhdh-community/rhdh:1.9.8, while the repository's
user-facing override example and image guide still reference the old floating :1.9 tag. This makes
the documented explicit configuration inconsistent with the pinned release configuration.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The Compose default was pinned to RHDH 1.9.8, but the commented environment override and container-image guide still reference the floating `:1.9` tag. Users following those instructions can explicitly run a different, unpinned image than the release default.

## Fix Focus Areas
- default.env[10-12]
- docs/rhdh-local-guide/container-image-guide.md[11-19]

## Recommended Fix
Update the commented `RHDH_IMAGE` example, guide text, and guide link to use `quay.io/rhdh-community/rhdh:1.9.8`, while preserving instructions for intentionally selecting other image tags where appropriate.
