OCPBUGS-45525: Expand CSP dev-mode documentation for plugin authors - #17430
Improves the Content Security Policy documentation in README.md to give console plugin authors clearer guidance on configuring CSP directives during local development.
Changes
Reorganized headings: Added a parent ## Content Security Policy (CSP) section with ### Violation Detection and ### Configuring For Development subsections for better structure
Spelled out abbreviation: First mention now reads "Content Security Policy (CSP)" for clarity
Supported directives: Added a #### Supported Directives section linking to the openshift/api type definitions, with a note that unrecognized directives cause a fatal error
Auto-appended directives: Documented the three directives the console server always appends (object-src 'self', frame-src 'none', frame-ancestors 'none'), correcting object-src from 'none' to 'self' to match the actual implementation in BuildCSPDirectives
Practical example: Replaced the old minimal example with a realistic plugin dev scenario showing script-src and connect-src for WebSocket hot-reload
Removed outdated content: Removed the "feature gate" note and the "In case of local developement" paragraph
Expands the Content Security Policy section in README.md to give dynamic plugin authors practical guidance on using the --content-security-policy CLI flag during local development.
Changes
Supported directives table: Documents all six configurable CSP directives (default-src, script-src, style-src, img-src, font-src, connect-src) with descriptions and automatic additions (nonce, unsafe-inline, data:)
Practical examples: Four common plugin dev scenarios — loading scripts from a dev server, connecting to external APIs/WebSocket, loading external fonts/images, and a combined multi-directive example with --csp-mode=enforce
Environment variable alternative: Documents BRIDGE_CONTENT_SECURITY_POLICY env var from start-console.sh as a convenient alternative to CLI flags
Debugging guide: How to identify and interpret CSP violations in the browser developer console
Enforcement context: Notes that OpenShift 5.2 will enforce CSP by default, encouraging plugin authors to test with --csp-mode=enforce now
Existing --csp-mode documentation and the ContentSecurityViolation Detection section are unchanged.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The README expands dynamic-plugin CSP setup instructions. It documents directive validation, appended directives, configuration examples, and environment variables for start-console.sh.

Summary
CSP directives and configuration README.md
Documents unsupported-directive errors and the appended directives object-src 'self', frame-src 'none', and frame-ancestors 'none'. Adds source examples and instructions for configuring CSP mode and directives through start-console.sh environment variables.
The documentation gap can cause plugin authors to configure invalid CSP keys and disrupt request handling.

Details
Needs approval from an approver in each of these files:
The "Automatic additions" column omits sources that the builder always emits.
The builder adds 'self' to every directive it emits. It also adds console.redhat.com to default-src, script-src, and connect-src, and https: to img-src. These additions apply in both on-cluster and off-cluster modes. The table lists none of them, so plugin authors who rely on it may add an HTTPS image origin that is already allowed, or may not know that console origins are already permitted.

Existing --csp-mode documentation and the ContentSecurityViolation Detection section are unchanged.
Expanded guidance for configuring Content Security Policy settings for dynamic plugins, including supported directives, their purposes, server-appended sources, localhost allowances, and directives that cannot be overridden.
Added practical command examples and documented environment-variable configuration through BRIDGE_CONTENT_SECURITY_POLICY and BRIDGE_CSP_MODE.
Changed the documented object-src value from 'none' to 'self'.
Removed the statement that CSP configuration is behind a feature gate.

Included review availability: This review used your included allowance. Your plan provides up to 12 included reviews per hour; 6 remain after this review.
The section omits the accepted CLI spellings for default-src and style-src. List all six keys so authors do not copy API enum names such as DefaultSrc.
An unsupported key can terminate Bridge when indexHandler builds the CSP, but it does not fail during initial startup. The existing API anchor is valid.
Suggested documentation update
The accepted CSP directive types mirror those defined in the
[openshift/api repository](https://github.com/openshift/api/blob/master/console/v1/types_console_plugin.go#L102-L137).
+The supported CLI keys are `default-src`, `script-src`, `style-src`, `img-src`,+`font-src`, and `connect-src`.
Using a directive not in that list causes the server to exit with a fatal error.

For context on the object-src 'self' change: the original implementation used object-src 'none' (hardcoded). This was changed to object-src 'self' by @jhadvig in commit 43c9c36 (April 28, 2025) as part of OCPBUGS-49291 — a refactor that restructured how CSP directives are built. The openshift/api doc comment example was never updated to reflect this change, so this PR aligns the documentation with the current implementation.
