Orientation for a session starting work on this codebase - reading order, where things live, which skill to use for which task, and the non-negotiable constraints. Use at the start of a session, when unsure where to look, or when the user asks how to approach a task here.

Hostile security and robustness audit of src/ assuming malicious traffic and 100x load. Use before releases, after large feature merges, or when the user asks for a security audit, adversarial review, or "what breaks under attack".
Holistic system audit for architecture drift, Hard Rules compliance, and async integrity across recently changed code. Use after completing a batch of tasks, before a release, or when the user asks for a health check or audit.
Semantic-correctness audit of hot-path code - enumerate the invariants a component must maintain, then hunt code paths that violate them (wrong answers, not crashes). Use after changing routing, eviction, accounting, or counter logic, before a release, or when metrics drift without any crash.
Plan, run, and interpret Locust load benchmarks (mock-backend and real-GPU) including A/B routing experiments. Use when the user wants to measure cache-hit ratio, TTFT, or throughput, compare routing modes, chase a benchmark regression, or design a benchmark experiment.
Triage build or runtime failures. Use when the user pastes a compile error, link error, runtime crash, test failure, or error log, or mentions a build failure.
Post-implementation maintenance - write unit tests, sync documentation, and update BACKLOG.md. Use after code is implemented and reviewed, or when the user asks for tests or doc updates for a change.

Task at hand: $ARGUMENTS
Ranvier Core is a Layer 7+ LLM traffic controller: C++20 on Seastar (shared-nothing, thread-per-core). It routes inference requests by token prefix to keep GPU KV-caches warm.
cmake/make/builds in this sandbox — Seastar deps are too heavy. Verification happens in the developer's Docker container; your job is to emit exact commands (Deferred Gates, see /validate) and never claim they passed..dev-context/claude-context.md are mandatory for all new and modified code. If you have not read them this session, read them before writing C++.std::shared_ptr, async-only I/O, bounded containers. When unsure whether a Seastar API works the way you think, verify against Seastar docs — do not guess.docs/ or assets/ (token-heavy). Read specific docs/internals/*.md files by name; grep .dev-context/cheatsheet.md (2500 lines of operational runbook) rather than reading it whole..dev-context/ (dated audits, investigations) are frozen — quote them, never edit them.CLAUDE.md (auto-loaded) → .dev-context/claude-context.md — architecture, layout, conventions, Hard Rules. Always.docs/internals/<area>.md deep-dive — authoritative for its area; must be updated in the same PR that changes its area..dev-context/README.md indexes everything else (pitfalls reference, sync map, investigations, audit records).

State the task type you've identified and invoke the matching skill. If the task spans several (most features do: plan → implement → review → doc → validate), say the sequence up front.
