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

@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 features: 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 category descriptions in lines 615-623 now reference "policy (feature-gated)", "branch chains", and "failure mode", but the example directory table below (lines 564-572) still uses the old descriptions. The two tables are now inconsistent — update the example directory table to match, or note which items are not yet represented in example configs.
