Review Summary

Documentation overhaul covering branch chains, gRPC detection, failure mode, and other capabilities. Nine findings, all Medium severity.

Broken links (2 target files, 4 link locations):

docs/filters/branch-chains.md -- referenced from features.md and configuration.md but does not exist
docs/architecture/pipeline-concepts.md -- referenced from features.md and configuration.md but does not exist. The PR description says "Add pipeline-concepts" but the file is not included.

Phantom entries (3 files, 5 items):

policy filter directory and cpex-policy-engine Cargo feature documented in crate-layout.md and features.md but neither exists in the codebase
endpoint_selector filter directory documented in crate-layout.md but does not exist
cargo xtask generate-filter-docs and lint-filter-docs documented in extensions.md but neither command exists in xtask/src/main.rs or the Makefile

Wrong version:

extensions.md bumps praxis-proxy-filter to "0.4" but the workspace version is 0.3.1

Table content mismatch:

security example config directory row lists items not present in that directory

9 inline comments, 1 body summary.

@praxis-bot can you review again?

Document shipped capabilities, refresh architecture placement wording for ingress and egress gateway use, expand configuration and example-config coverage, and point AI Gateway readers to praxis-ai without overstating forward-proxy or mesh claims. Signed-off-by: Ricardo Pchevuzinske Katz <katz@redhat.com>

Keep architecture overview focused on design principles and short primary use-cases; trim redundant placement wording elsewhere. Signed-off-by: Ricardo Pchevuzinske Katz <katz@redhat.com>

PR Review

Summary: Documentation overhaul refreshing features, crate layout, and configuration docs for shipped capabilities, with new AI Gateway cross-references.

Overall: Good restructuring with clear cross-repo links to praxis-ai. However, several new references point to files and features that do not exist in the current codebase, which will create broken links and document phantom capabilities.

[Large] Phantom feature: the policy filter and cpex-policy-engine Cargo feature do not exist in the codebase — no filter module under filter/src/builtins/http/security/policy, no feature in any Cargo.toml. Similarly, endpoint_selector (line 237) has no implementation. Documenting unimplemented features as current capabilities is misleading. Move these to the "Planned" section or remove them until implemented.

[Medium] The security row now lists "policy (feature-gated)" and the pipeline row lists "failure mode, branch chains", but the example directory table below (line 567) still shows the old descriptions without these additions. The table rows are now inconsistent — update the example directory table to match the expanded category descriptions, or vice versa.
