+"""Dry-run wrapper(s) around Agent Shin GitHub mutations.
+
+The rollout scripts currently need only one mutation wrapped, so this module
+exposes a single ``maybe_post_comment`` helper. It takes a ``dry_run: bool``
+keyword argument and the body is intentionally trivial:
+
+    if dry_run:
+        print(...)        # log what we would do, return
+        return
+    real_mutation(...)    # otherwise, actually do it
+
+That shape means a dry-run preview differs from the real run in exactly one
+line per side effect: the call site. So when you `python3 script.py` locally
+without ``--close``, you can be confident the actions printed are the ones the
+GitHub Action would have performed (modulo ordering on retry/error paths,
+which are deliberately simple). Any further mutation a rollout script needs
+should get the same ``maybe_*`` treatment instead of calling the raw
+``triage_with_llm`` mutation directly.
+
+Importing from this module pulls in the real mutation from ``triage_with_llm``
+— call sites in the rollout scripts should NEVER import ``post_comment``
+directly; that would skip the dry-run gate and is the bug class this module
+exists to prevent.

+
+Both `triage_with_llm.py` (the LLM-judge entrypoint) and
+`close_low_quality_prs.py` (the daily Greptile-score sweep) need to
+agree on the same notions of:
+
+  * What counts as a Greptile-authored review comment
+    (``GREPTILE_BOT_LOGINS``) and how to extract a confidence score from
+    its body (``SCORE_PATTERN`` / :func:`extract_greptile_score`).
+  * How long the 2-hour grace window is (``GRACE_PERIOD_SECONDS``) and
+    the HTML marker stamped into a grace-warning comment so the *other*
+    script can see "Agent Shin already warned" and behave accordingly
+    (``GRACE_COMMENT_MARKER``).
+  * Who Agent Shin is on GitHub (``AGENT_SHIN_DEFAULT_BOT_LOGIN``).
+  * How GitHub-style ISO-8601 timestamps round-trip into timezone-aware
+    :class:`datetime.datetime` (:func:`parse_iso8601`).
+
+Keeping these in one module means a future change (new Greptile output
+format, a longer grace window, a new allowlisted account) is a single edit

+Auto-close low-quality pull requests.
+
+Closes open PRs (including drafts, regardless of age) that satisfy ALL of:
+  1. Have a Greptile (`greptile-apps`) review comment whose latest
+     "Confidence Score: X/5" is below the configured threshold (default: 4).
+  2. Are authored by an external OSS contributor (internal BerriAI
+     contributors are exempt).
+  3. Do not carry an opt-out label (default: "do not close").
+
+`--min-age-days` is retained as an opt-in safety net for one-off backfill
+runs (default: 0). The team's intent is that the count of open PRs equals
+the count of PRs internal collaborators need to action on, so neither age
+nor draft status acts as a free pass.
+
+For each match, the script posts an explanatory comment and closes the PR.
+Because OSS contributors *cannot* reopen a PR closed by the bot/maintainer
+(GitHub limitation), the close-comment instructs them to push their fixes
+and **open a fresh PR**, or to comment `@agent-shin reconsider` on the
+closed PR to have the LLM judge re-evaluate (and reopen on pass).
+
+Requires the `gh` CLI to be authenticated.
+
+Usage examples:
+    # Dry run (default) - prints what would be closed
+    python3 close_low_quality_prs.py
+
+    # Actually close matching PRs

+"""One-shot 7-day heads-up sweep for the Agent Shin rollout.
+
+Posts a friendly "the OSS triage bot kicks in next Monday" comment on every
+open external PR/issue that currently *would* fail the new rubric — i.e.,
+every PR/issue Agent Shin would close once the rollout completes. The point
+is to give contributors a full week to fix their description before the bot
+ever takes a destructive action, so nobody is surprised by an auto-close.
+
+The script is designed to run **exactly once** at rollout, fired by a manual
+``workflow_dispatch`` (``dry_run=false``) on the heads-up workflow. Re-runs
+are safe: every comment is stamped with the hidden ``HEADS_UP_MARKER`` and
+PRs/issues that already carry the marker are skipped.
+
+Dry-run vs. real run
+--------------------
+Defaults to dry-run. Passing ``--close`` flips into real mode. Every GitHub
+mutation goes through ``_agent_shin_actions``, which has a one-line
+``if dry_run: log else: do_it`` per call, so the only difference between a
+dry-run preview and the real run is the call site that actually hits the
+GitHub API.
+
+Local preview::
+
+    python3 .github/scripts/triage_rollout_heads_up.py --repo BerriAI/litellm
+
+Real run (the manual rollout dispatch uses this)::
+
+    python3 .github/scripts/triage_rollout_heads_up.py --repo BerriAI/litellm --close

+# new triage bot would auto-close. The real sweep is a deliberate one-shot:
+# trigger it at rollout via a manual `workflow_dispatch` with `dry_run=false`.
+# The script is idempotent (skips items that already carry the

+# The automatic push trigger runs DRY-RUN only, so merging the script to

+# workflow is wired up. Posting real comments requires the manual dispatch,
+# which is also the only trigger that exposes `OPENAI_API_KEY`. The heads-up
+# is intentionally NOT gated on `AGENT_SHIN_ENABLED`: it has to warn
+# contributors while that flag is still off, ahead of the flip that turns on

 `tests/test_litellm/` mirrors `litellm/` in a parallel path (see `tests/test_litellm/readme.md`). Name tests `test_<filename>.py`, but always match the existing test file in the directory you touch — many provider dirs use longer descriptive names (e.g. `test_anthropic_chat_transformation.py`) to avoid ambiguity across sibling folders. For bug fixes, extend the existing mapped test file rather than creating a new one. Only create a new test file for a new feature (provider, endpoint, or transformation module) that has no mapped test yet, following that directory's naming convention (or `test_<filename>.py` if you're the first test there).

 Never use `pytest` commands or the like as "Screenshots / Proof of Fix".

Also, it should hit real LLM provider APIs, not mocks, and cost real $$$ because that is the most realistic test. The proof of fix should be exactly what the end user / customer would see / do. The run logs in PR #27703 is a prime example of how to do it (not a huge fan of using a python test script that future me and the team will have no visibility into; I prefer just curl commands or a short list of bash commands (e.g., using `for`)).

+Run tests before you commit. Also, run `make pre-commit` right before each commit, which generates types (as needed) and formats/lints your code. Any errors found must be fixed. It only runs when there are staged frontend and/or backend changes and calculates violations, generates types, etc. based on the worktree, so stage what you need or stash/delete unwanted files in litellm/ or ui/ (where backend and frontend lint run, respectively) before running it. If it fails because dashboard api types are stale, it already regenerated them for you. You just need to stage the schema.d.ts, re-run `make pre-commit` to confirm it passes, and commit

-When you must use real LLM models to, for example, write e2e tests, write a QA runbook, etc., make sure to use the latest models (doesn't have to be smartest, can also be a modern small, fast one. No strong preference for smart vs fast here, just use something modern) as of the year and month of the current date. Do a web search as necessary to figure that out
+If you're trying to create a new function that relies on untyped stuff, instead of adding more Any's and pushing `reportAny` / `reportExplicitAny` closer to their basedpyright ceilings, just validate it in the caller with Pydantic (a model or `TypeAdapter` that returns the typed thing or raises will do) and then pass the now typed variable in
+
+If you get an LIT001 or LIT002 fail, refactor the code to follow functional programming best practices rather than introducing mutable data structures. For example, build values in one shot with comprehensions or generators wrapped in `tuple()` / `frozenset()` instead of seeding an empty `list`/`dict`/`set` and mutating it over time. Ideally `# mutable-ok` is never used; reach for it only as a genuine last resort when an immutable rewrite is truly impossible, and always pair it with a real reason

That's the indication that you should replace that company name with "the customer". e.g. not "Model request from Acme (Pylon #1234)" but "Model request from a customer (Pylon #1234)". This is because the codebase is public. The only exception is for publicly known providers or vendors such as OpenAI, Anthropic, AWS Bedrock, etc. only IF we're adding support for that provider/vendor in general and NOT if that PR or whatnot was a request by one of them, and they're actually one of our customers.

-# XecGuard
-
-Use [XecGuard](https://www.cycraft.com/) (CyCraft) to protect your LLM applications with multi-policy scanning (prompt injection, harmful content, PII, system-prompt enforcement, skills protection) and RAG context grounding validation. XecGuard is a cloud-hosted AI security gateway — there are no self-hosting requirements.
-
-## Quick Start
-
-### 1. Define Guardrails on your LiteLLM config.yaml
-
-```yaml showLineNumbers title="config.yaml"
-model_list:
-  - model_name: gpt-4
-    litellm_params:
-      model: openai/gpt-4
-      api_key: os.environ/OPENAI_API_KEY
-
-guardrails:
-  - guardrail_name: "xecguard-guard"
-    litellm_params:
-      guardrail: xecguard
-      mode: "pre_call"
-      api_key: os.environ/XECGUARD_API_KEY
-      api_base: os.environ/XECGUARD_API_BASE   # Optional
-      policy_names:                             # Optional — defaults to System Prompt Enforcement + Harmful Content Protection
-        - Default_Policy_SystemPromptEnforcement
-        - Default_Policy_HarmfulContentProtection
-```
-
-#### Supported values for `mode`
-
-- `pre_call` — Run **before** the LLM call to validate **user input**
-- `post_call` — Run **after** the LLM call to validate **model output** (also runs context grounding when RAG documents are provided)
-- `during_call` — Run **in parallel** with the LLM call for input validation
-- `logging_only` — Run as an **observe-only** callback; records scan decisions without blocking
-
-### 2. Set Environment Variables
-
-```shell
-export XECGUARD_API_KEY="xgs_<your-service-token>"
-export XECGUARD_API_BASE="https://api-xecguard.cycraft.ai"   # Optional, this is the default
-export XECGUARD_BLOCK_ON_ERROR="true"                        # Optional, fail-closed by default
-```
-
-### 3. Start LiteLLM Gateway
-
-```shell
-litellm --config config.yaml --detailed_debug
-```
-
-### 4. Test request
-
-<Tabs>
-<TabItem label="Blocked Request" value="blocked">
-
-Test input validation with a prompt-injection / system-prompt bypass attempt:

-```
-
-### Required
-
-| Parameter | Description |
-|-----------|-------------|
-| `api_key` | XecGuard **Service Token** (prefix `xgs_`). Falls back to `XECGUARD_API_KEY` env var. |
-
-### Optional
-
-| Parameter | Default | Description |
-|-----------|---------|-------------|
-| `api_base` | `https://api-xecguard.cycraft.ai` | XecGuard API base URL. Falls back to `XECGUARD_API_BASE` env var. |
-| `xecguard_model` | `xecguard_v2` | XecGuard scanning model identifier. |
-| `policy_names` | `["Default_Policy_SystemPromptEnforcement", "Default_Policy_HarmfulContentProtection"]` | Policies applied on each scan. See [Available Policies](#available-policies) below. |
-| `block_on_error` | `true` | Fail-closed by default. Set to `false` for fail-open behaviour (requests pass through when the XecGuard API is unreachable). |
-| `grounding_strictness` | `BALANCED` | Either `BALANCED` or `STRICT`. Controls how strictly the `/grounding` endpoint evaluates response fidelity to supplied context documents. |
-| `default_on` | `false` | When `true`, the guardrail runs on every request without needing to specify it in the request body. |
-
-## Available Policies
-
-XecGuard ships with six built-in default policies. Select one or more via `policy_names`:
-
-| Policy Name | Purpose |
-|-------------|---------|
-| `Default_Policy_SystemPromptEnforcement` | Ensures the user prompt stays within the tasks defined by the system prompt |
-| `Default_Policy_GeneralPromptAttackProtection` | Detects prompt injection, prompt extraction, encoded bypass attempts |
-| `Default_Policy_ContentBiasProtection` | Detects discrimination, harassment, harmful stereotypes |
-| `Default_Policy_HarmfulContentProtection` | Detects harmful speech/semantics violating public order and good morals |
-| `Default_Policy_SkillsProtection` | Detects malicious content in AI-agent skill files |
-| `Default_Policy_PIISensitiveDataProtection` | Detects personally identifiable information (PII) |
-
-:::info
-The wildcard form `policy_names: ["*"]` is supported by the XecGuard API but requires your Service Token to be pre-bound to at least one policy in the XecGuard console.
-:::
-
-## Context Grounding (RAG)
-
-When scanning in `post_call` mode, XecGuard can additionally validate the assistant's response against reference documents via the `/grounding` endpoint. This catches hallucinations and factual drift in RAG applications.
-
-Supply grounding documents at request time via the `metadata.xecguard_grounding_documents` field. Each document is `{document_id, context}`:
-
-```shell
-curl -i http://0.0.0.0:4000/v1/chat/completions \
-  -H "Content-Type: application/json" \
-  -d '{
-    "model": "gpt-4",
-    "messages": [
-      {"role": "user", "content": "What nationality was Peggy Seeger?"}
-    ],
-    "guardrails": ["xecguard-guard"],
-    "metadata": {
-      "xecguard_grounding_documents": [
-        {
-          "document_id": "peggy_seeger_bio",
-          "context": "Peggy Seeger (born June 17, 1935) is an American folk singer."
-        }
-      ]
-    }
-  }'
-```
-
-If the assistant's response contradicts or is unsupported by the provided documents, the request is blocked with a grounding violation (`CONFLICT`, `BASELESS`, or `INCOMPLETE`):
-
-```json
-{
-  "error": {
-    "message": "Blocked by XecGuard grounding: rules=[CONFLICT] trace_id=fabcde7890123456abcdef1234567829 rationale=Response states Peggy Seeger was British, but the document indicates she is American.",
-    "type": "None",
-    "param": "None",
-    "code": "400"
-  }
-}
-```
-
-Grounding only runs when:
-- `mode` includes `post_call`
-- `metadata.xecguard_grounding_documents` is a non-empty list
-- The messages contain both a user prompt and an assistant response
-
-## Advanced Configuration
-
-### Fail-Open Mode
-
-By default XecGuard operates in **fail-closed** mode — if the API is unreachable, the request is blocked. Set `block_on_error: false` to allow requests through when the guardrail API fails:
-
-```yaml
-guardrails:
-  - guardrail_name: "xecguard-failopen"
-    litellm_params:
-      guardrail: xecguard
-      mode: "pre_call"
-      api_key: os.environ/XECGUARD_API_KEY
-      block_on_error: false
-```
-
-### Input + Output Pipeline
-
-Apply one guardrail for input validation and another for output scanning + grounding:
-
-```yaml
-guardrails:
-  - guardrail_name: "xecguard-input"
-    litellm_params:
-      guardrail: xecguard
-      mode: "pre_call"
-      api_key: os.environ/XECGUARD_API_KEY
-      policy_names:
-        - Default_Policy_GeneralPromptAttackProtection
-        - Default_Policy_SystemPromptEnforcement
-
-  - guardrail_name: "xecguard-output"
-    litellm_params:
-      guardrail: xecguard
-      mode: "post_call"
-      api_key: os.environ/XECGUARD_API_KEY

-        - Default_Policy_PIISensitiveDataProtection
-      grounding_strictness: "STRICT"
-```
-
-### Always-On Protection
-
-Enable the guardrail for every request without specifying it per-call:
-
-```yaml
-guardrails:
-  - guardrail_name: "xecguard-guard"
-    litellm_params:
-      guardrail: xecguard
-      mode: "pre_call"
-      api_key: os.environ/XECGUARD_API_KEY
-      default_on: true
-```
-
-### Logging-Only Mode
-
-Observe scan decisions without blocking — useful for shadow-mode deployment before enforcement:
-
-```yaml
-guardrails:
-  - guardrail_name: "xecguard-monitor"
-    litellm_params:
-      guardrail: xecguard
-      mode: "logging_only"
-      api_key: os.environ/XECGUARD_API_KEY
-```
-
-Scan results are attached to the standard logging payload (`standard_logging_guardrail_information`) and surface in Langfuse / DataDog / OTEL without ever blocking a request.
-
-## Full Conversation History
-
-XecGuard always receives the **full conversation history** — system, user, and assistant messages — for both input and response scans. This is required for policies such as `Default_Policy_SystemPromptEnforcement` to work correctly. There is no configuration option to disable this behaviour; the framework-wide `skip_system_message_in_guardrail` setting is intentionally ignored for XecGuard.
-
-## Error Handling
-
-**Missing API Credentials:**
-```
-XecGuardMissingCredentials: XecGuard API key is required.
-Set XECGUARD_API_KEY in the environment or pass api_key in the guardrail config.
-```
-
-**API Unreachable (fail-closed, default):**
-The request is blocked and a `GuardrailRaisedException` is raised.
-
-**API Unreachable (fail-open, `block_on_error: false`):**
-The request passes through unchanged and a warning is logged.

+# Adding a provider / route to litellm-rust
+
+Three layers, same for every route (see `ocr` and `realtime` as references):
+
+1. **Transform contract (pure)** — `crates/core/src/<route>/transformation.rs`: a `…ProviderConfig` trait (URL build + request/response transforms) + types in `types.rs`. No network, env, or auth.
+2. **Provider config (pure)** — `crates/providers/src/<provider>/<route>/transformation.rs`: implement that trait as a `const <PROVIDER>_<ROUTE>_CONFIG`, mirroring the Python provider tree. Add parity unit tests.
+3. **HTTP / transport (the host)** — `crates/providers/src/<route>.rs` (e.g. `ocr.rs`, `realtime.rs`): the callable fn (`run_ocr`, `realtime`). It resolves the key, builds the auth header, builds URL + transforms via the config, then does the network call. This is the only layer allowed to do I/O.
+
+**Calling:** the host invokes the route fn — the Python bridge calls `run_ocr`; the `ai-gateway` server calls `realtime`. Register new modules in `lib.rs` / `mod.rs`, then run `cargo fmt && cargo clippy --workspace -- -D warnings && cargo test --workspace`.

+# AGENTS.md
+
+litellm-rust has exactly THREE crates. A crate is a LAYER, not a route. Routes (ocr, realtime, chat) and providers (mistral, openai) are MODULES inside the layers.
+
+## Crates
+
+| Crate | Role | Pure / I/O |
+|-------|------|------------|
+| litellm-core | Translation layer — types, route contracts (traits), provider transforms (modules under providers/), and the router. Builds requests/responses; no network. | Pure |
+| litellm-ai-gateway | Routes + host — the only crate that touches the network. HTTP/WebSocket I/O (modules under io/) plus the axum server binary (behind the `server` feature). | I/O |
+| litellm-python-bridge | PyO3 cdylib exposing Rust to the litellm Python SDK — a thin adapter over litellm-ai-gateway's I/O. | Binding |
+
+Dependency direction (acyclic): litellm-core ← litellm-ai-gateway ← litellm-python-bridge.
+
+Adding a crate: default to a MODULE. New crate ONLY on a real trigger — separate artifact (binary/cdylib), proc-macro, shared foundation, or publishable standalone. A new provider or route is none of these.
+
+Adding a crate fails crates/core/tests/workspace_crate_allowlist.rs until you update its allowlist and this file — intentional.

+# CLAUDE.md
+
+This file defines the rules for Rust work in LiteLLM.
+
+## Crates (exactly three — see AGENTS.md)
+
+`litellm-core` describes work; `litellm-ai-gateway` executes it; `litellm-python-bridge`
+exposes it to the Python SDK. A crate is a **layer**, not a route — add modules, not crates.
+
+## Core Boundary
+
+`litellm-core` is the pure translation layer; the `litellm-ai-gateway` host executes work.
+
+Route-level Rust structure mirrors LiteLLM's Python responsibilities:
+- `core/src/<route>/` owns the route contract, shared types, and provider
+  template traits. For OCR, this means `core/src/ocr`.
+- `core/src/providers/<provider>/<route>/transformation.rs` owns the
+  provider-specific transform. For Mistral OCR, this means
+  `core/src/providers/mistral/ocr/transformation.rs`.
+- Network execution lives in the host crate `ai-gateway` (`ai-gateway/src/io/`),
+  never inside `core`.
+
+Allowed in `core`:
+- Pure request transforms
+- Pure response transforms
+- Pure stream chunk normalization
+- Shared data types and validation errors
+- Deterministic token/cost helper logic
+
+Not allowed in `core`:
+- Network calls
+- Environment variable or secret reads
+- Filesystem access
+- Database or cache access
+- Provider SDK signing or auth flows
+- Logging callbacks, spend writes, or custom callbacks
+- Global mutable runtime state
+
+Python owns rollout state and fallback while Rust is being introduced. Rust
+paths must be off by default until parity tests prove equivalence with Python.
+
+## Production Bar
+
+Rust code in this workspace is held to a strict parity and robustness bar from
+the first PR:
+
+- Correctness parity is proven with tests. Do not rely on README claims or
+  manual inspection for a port that mirrors Python behavior.
+- Every provider transform must have unit tests for supported-parameter
+  filtering, request body shape, response normalization, missing/null fields,
+  and bad-input errors.
+- When Rust is exposed through Python, add Python tests that prove disabled,
+  enabled, and unavailable-bridge fallback behavior.
+- Avoid panics on user/provider input. Return typed errors and let the host map
+  them to Python exceptions or HTTP responses.
+- OCR handles documents that often contain personal data. Do not log document
+  contents, base64 payloads, provider response bodies, or secrets.
+- Error messages must be useful but data-minimized. Truncate or sanitize any
+  upstream body before it crosses a host boundary.
+- Treat empty or whitespace-only credentials, URLs, and config values as absent
+  at the host/config resolution layer.
+- Preserve Python output shape intentionally. If a field is always serialized as
+  `null` for Python parity, leave a short comment explaining that parity choice.
+
+## Host I/O Rules
+
+These rules apply when adding future crates or modules that execute network I/O,
+such as `ai-gateway`, router hosts, or standalone servers:
+
+- Set connect and full-request timeouts. No unbounded waits.
+- Reuse HTTP clients; do not construct clients per request.
+- Prefer rustls TLS for portable Python wheels and Linux images unless there is
+  a documented reason not to.
+- Add request IDs and structured tracing at the host layer, without logging OCR
+  document contents or secrets.
+- Do not echo raw upstream response bodies to callers. Sanitize and bound them.
+- Avoid `expect`/`unwrap` in server startup and request paths unless the panic is
+  impossible by construction and documented.
+
+## Constants
+
+Magic numbers and fixed strings go in a crate-level `constants.rs`, never
+hardcoded inline — the Rust mirror of Python's `litellm/constants.py`.
+
+- Each crate that needs them has `src/constants.rs` (declared `mod constants;`);
+  import from it (`use crate::constants::...`). Don't scatter `const` values at
+  the top of feature modules.
+- An env-overridable tunable still lives in `constants.rs` as its `DEFAULT_*`
+  value; the env read (with fallback to that default) happens at the host/config
+  resolution layer, not in `core`/`providers`.
+- Exception: a value that is purely local to one function and has no meaning
+  elsewhere may stay inline, but prefer `constants.rs` when in doubt.
+
+## Checks
+
+Run these before pushing Rust changes. The same checks run in GitHub Actions
+for changes under `litellm-rust/`.
+
+```bash
+cd litellm-rust
+cargo fmt --check
+# the ai-gateway binary + server code is behind the `server` feature
+cargo clippy -p litellm-ai-gateway --all-targets --features server -- -D warnings
+cargo clippy -p litellm-core -p litellm-python-bridge --all-targets -- -D warnings
+cargo test --workspace
+```
+
+When a Rust path is exposed through Python, add Python parity tests that compare
+the existing Python output with the Rust-backed output.

+# LiteLLM Rust
+
+This workspace contains the staged Rust implementation for LiteLLM.

+Rust starts as a pure transform core used by the existing Python host. Python

+  python/            # Python interop (feature: python-config) — load-time only
+    mod.rs, config.rs, AGENTS.md
+```
+
+## Rules
+
+- **Routes follow one template.** Each route module exposes
+  `pub fn router() -> Router<AppState>`; `routes/mod.rs` only merges them. Simple
+  routes are one file; non-trivial routes are a folder (`handler`/`service`/
+  `transport`). See `routes/AGENTS.md`.
+- **Auth is an extractor.** Add `crate::auth::RequireMasterKey` to a handler's
+  args; it runs during extraction. Never re-implement the check per route.
+- **Handlers are thin.** A handler validates and delegates to its `service`. No
+  business logic, no provider calls, no transforms in handlers.
+- **State is shared and cheap to clone.** Long-lived handles live behind `Arc` in
+  `state.rs`; read env/config only in `main.rs` when building state.
+
+## Auth (interim)
+
+A single **master key** (`LITELLM_MASTER_KEY`), enforced by the
+`auth::RequireMasterKey` extractor: any caller presenting it as
+`Authorization: Bearer <key>` may invoke the gateway. Fails closed (500) when
+unset; constant-time compare. The server binds `127.0.0.1` by default (`HOST` to
+override). Full per-key auth + budgets/rate-limits are delegated to the Python
+proxy in a later phase. Health routes don't add the extractor (unauthenticated).
+
+## Python interop
+
+Anything that calls into Python lives in `python/` and is **load-time only** — see
+`python/AGENTS.md`. The realtime data path never takes the GIL.

+- **Client endpoint:** `wss://<host>/v1/realtime?model=<model>` (WebSocket)
+- **Auth:** `Authorization: Bearer $LITELLM_MASTER_KEY` (fails closed if unset)
+- **Health:** `GET /health/readiness`, `GET /health/liveness`, `GET /health/gil`
+- **Request logs:** POSTed to a LiteLLM proxy at `/v1/rust_control_plane/logs` (see [Request logging](#request-logging))
+
+> **Realtime serving is pure Rust.** Python is used at **load time only** — to
+> read the config once at boot. The realtime hot path never touches Python.
+
+## Configuration (config.yaml)
+
+The gateway loads its `model_list` from a **config.yaml**, the same as the
+LiteLLM proxy. Point `LITELLM_CONFIG_PATH` at the file:
+
+```yaml
+# config.yaml
+model_list:
+  - model_name: gpt-realtime
+    litellm_params:
+      model: openai/gpt-realtime
+      api_key: os.environ/OPENAI_API_KEY
+```
+
+```bash
+LITELLM_CONFIG_PATH=./config.yaml ./litellm-ai-gateway
+```
+
+At boot the gateway calls into `litellm.proxy.read_model_list`, which reuses the
+**real proxy config reader** (`ProxyConfig.get_config`). That means everything
+the proxy supports in config.yaml works here too:
+
+- `include:` to merge in other config files,
+- `os.environ/VAR` secret references (resolved via the secret manager, never
+  inlined),
+- DB-stored models (when a database is configured).
+
+Secrets stay out of the config — reference them with `os.environ/...` and set
+the env var at deploy time. The shipped Docker image is built with the
+`python-config` feature and **bundles litellm**, so config loading works out of
+the box; the default baked config lives at `/app/config.yaml` and can be
+overridden at deploy time (e.g. a Render secret file mounted at the same path).
+
+### Environment variables
+
+| Var | Required | Default | Purpose |
+|---|---|---|---|
+| `LITELLM_CONFIG_PATH` | yes (config mode) | — | Path to the config.yaml the gateway loads its `model_list` from. The Docker image defaults this to `/app/config.yaml`. |
+| `LITELLM_MASTER_KEY` | yes | — | Bearer token clients must send. Unset ⇒ all `/v1/realtime` requests are rejected (fail closed). |
+| `OPENAI_API_KEY` | yes | — | Upstream OpenAI key. Referenced by config.yaml as `os.environ/OPENAI_API_KEY` for the gateway→OpenAI dial. |
+| `HOST` | no | `127.0.0.1` | **Set to `0.0.0.0` in any container/deploy** or external traffic is refused. |
+| `PORT` | no | `4001` | Listen port. Render and most PaaS inject this automatically. |
+| `LITELLM_PROXY_BASE_URL` | no | `http://localhost:4000` | LiteLLM proxy that request logs are POSTed to. See [Request logging](#request-logging). |
+
+> Secrets (`LITELLM_MASTER_KEY`, `OPENAI_API_KEY`) are never baked into the image
+> or `render.yaml` — inject them at deploy time only.
+
+### Lean env stand-in (fallback)
+
+If the binary is built **without** `python-config` (default features), or
+`LITELLM_CONFIG_PATH` is unset, the gateway falls back to a single-deployment
+stand-in built from the environment:
+
+| Var | Default | Purpose |
+|---|---|---|
+| `OPENAI_REALTIME_MODEL` | `gpt-realtime` | The single deployment's model name (also the `?model=` clients pass). |
+
+This mode links no libpython and needs no config file, but it only supports one
+hard-coded OpenAI deployment. **config.yaml is the recommended path** — use the
+stand-in only for the leanest possible build.
+
+## Request logging
+
+The gateway runs no spend logic. When a session ends it builds one
+`StandardLoggingPayload` and POSTs it to `{LITELLM_PROXY_BASE_URL}/v1/rust_control_plane/logs`
+(admin-only, bearer = `LITELLM_MASTER_KEY`), and the proxy replays it through its
+normal callbacks (spend logs, Langfuse, etc.). The POST is non-blocking: a bounded
+channel drained by a background worker, dropping with a counter if the proxy is
+down. It sends one payload per session. Both env vars are in the table above.
+
+Worker tuning, rarely needed: `LITELLM_LOG_CHANNEL_CAPACITY` (4096),
+`LITELLM_LOG_BATCH_SIZE` (256), `LITELLM_LOG_FLUSH_INTERVAL_MS` (500).
+
+## Build & run with Docker
+
+The image is built `--features python-config` and installs litellm **from this
+repo's source** (the config reader is newer than any PyPI release), so the build
+**context is the repo root**:
+
+```bash
+# from the repo root
+docker build -f litellm-rust/crates/ai-gateway/Dockerfile -t litellm-ai-gateway .
+
+docker run --rm -p 4001:4001 \
+  -e HOST=0.0.0.0 -e PORT=4001 \
+  -e LITELLM_MASTER_KEY=sk-local \
+  -e OPENAI_API_KEY=$OPENAI_API_KEY \
+  litellm-ai-gateway          # LITELLM_CONFIG_PATH defaults to /app/config.yaml
+
+# smoke test
+curl -s -o /dev/null -w '%{http_code}\n' localhost:4001/health/readiness   # -> 200
+curl -s -o /dev/null -w '%{http_code}\n' localhost:4001/v1/realtime         # -> 401 (auth fails closed)
+```
+
+On boot you should see `loaded model_list from /app/config.yaml via python
+config reader` — that confirms the config path (not the env stand-in fallback).
+To use your own config, mount it over the default:
+
+```bash
+docker run --rm -p 4001:4001 \
+  -e HOST=0.0.0.0 -e LITELLM_MASTER_KEY=sk-local -e OPENAI_API_KEY=$OPENAI_API_KEY \
+  -v $(pwd)/my-config.yaml:/app/config.yaml:ro \
+  litellm-ai-gateway
+```
+
+### Cargo-only (no Docker)
+
+```bash
+# config.yaml mode — needs litellm importable in the active python env
+LITELLM_CONFIG_PATH=./crates/ai-gateway/config.yaml \
+  cargo run --release -p litellm-ai-gateway --features python-config
+
+# env stand-in mode — no python, no config
+cargo run --release -p litellm-ai-gateway
+```
+
+## Deploy on Render
+
+The service is a Docker **web service**; Render terminates TLS and supports
+WebSockets, so the public endpoint is `wss://<service>.onrender.com/v1/realtime`.
+
+### Option A — Blueprint (`render.yaml`)
+
+`crates/ai-gateway/render.yaml` describes the service (Docker runtime,
+`healthCheckPath: /health/readiness`, repo-root `dockerContext: .`,
+`dockerfilePath: ./litellm-rust/crates/ai-gateway/Dockerfile`,
+`LITELLM_CONFIG_PATH: /app/config.yaml`). `LITELLM_MASTER_KEY` and
+`OPENAI_API_KEY` are `sync: false` — set them in the dashboard after the first
+deploy. To use a non-default model_list, mount a **Render Secret File** at
+`/app/config.yaml`. Point a Render Blueprint at this repo/branch and apply.
+
+### Option B — Render API
+
+```bash
+# create a Docker web service from this repo+branch, then set env vars:
+curl -X POST https://api.render.com/v1/services \
+  -H "Authorization: Bearer $RENDER_API_KEY" -H "Content-Type: application/json" \
+  -d '{
+    "type": "web_service", "name": "litellm-rust-ai-gateway",
+    "ownerId": "<owner-id>", "repo": "https://github.com/BerriAI/litellm",
+    "branch": "<branch-with-this-dockerfile>",
+    "serviceDetails": {
+      "env": "docker",
+      "envSpecificDetails": {
+        "dockerfilePath": "./litellm-rust/crates/ai-gateway/Dockerfile",
+        "dockerContext": "."
+      },
+      "healthCheckPath": "/health/readiness"
+    }
+  }'
+# then set env vars LITELLM_MASTER_KEY, OPENAI_API_KEY, HOST=0.0.0.0,
+# LITELLM_CONFIG_PATH=/app/config.yaml
+```
+
+Health check path **must** be `/health/readiness`. `autoDeploy` is off by default
+in the blueprint — trigger deploys manually (or flip it on) to pick up new commits.
+
+## Scaling
+
+Concurrency is what matters, not total connections: each in-flight session holds
+one client socket + one upstream socket. To scale, raise the instance count /
+enable autoscaling on the Render service (e.g. baseline 10, max 100). Each
+instance needs file descriptors for `2 × peak_concurrent_sessions` — raise
+`ulimit -n` if you push very high concurrency.
+
+## Latency note
+
+The gateway adds the cost of one extra hop: client→gateway, then a fresh
+gateway→OpenAI realtime handshake (TLS + WS upgrade + `session.created`). In
+benchmarks this is ~100–150 ms of added session-establishment time; first-audio
+and steady-state streaming add no measurable overhead. To minimize it, deploy the
+gateway in the Render region with the lowest RTT to OpenAI's realtime endpoint.

+# Realtime gateway benchmark — pool on/off
+
+Measures what the gateway adds over talking to OpenAI's realtime WebSocket
+directly, and what the pre-warmed connection pool removes. See
+`../../src/routes/realtime/README.md` for how the pool works.
+
+## Results
+
+5000 calls / 500 concurrency, gateway at 10 instances, pool ON
+(`REALTIME_POOL_SIZE=64`), upstream OpenAI `gpt-realtime`. Each leg run twice.
+Times in **ms**. Phases per connection: **dial** = TCP+TLS+WS upgrade,
+**session** = upgrade → `session.created` (the phase the pool removes),
+**1st-audio** = `response.create` → first audio delta (OpenAI inference),
+**total** = full wall-clock.
+
+| metric             | Direct OpenAI | Gateway (pool ON) | Overhead (ms) | vs OpenAI  |
+| ------------------ | ------------- | ----------------- | ------------- | ---------- |
+| success rate (%)   | 99.8          | 99.8              | —             | —          |
+| dial p50 (ms)      | 276           | 158               | −118          | **faster** |
+| session p50 (ms)   | 7             | 0                 | −7            | **faster** |
+| 1st-audio p50 (ms) | 440           | 664               | +224          | slower¹    |
+| total p50 (ms)     | 816           | 1010              | +194          | slower¹    |
+| total p95 (ms)     | 2152          | 1970              | −182          | **faster** |
+| total p99 (ms)     | 2692          | 2610              | −82           | **faster** |
+
+The gateway is **faster than direct on 4 of 6 metrics**. The warm pool makes the
+**session phase sub-millisecond** at the median — ~76% of connects hit the pool,
+~70% had session < 1 ms. ¹ The two "slower" rows are not gateway overhead:
+`1st-audio` is OpenAI's own inference time (the gateway only relays it), which ran
+slower during the gateway legs and drags `total p50` with it.
+
+**Pool OFF** (control, `REALTIME_POOL_SIZE=0`): session p50 was **367 ms** — the
+fresh-dial overhead the pool removes.
+
+## Reproduce
+
+The load generator lives in a separate repo:
+**https://github.com/ishaan-berri/litellm-realtime-bench**
+
+```bash
+git clone https://github.com/ishaan-berri/litellm-realtime-bench
+cd litellm-realtime-bench && go build -o wsbench .
+
+# Direct to OpenAI (baseline)
+./wsbench -host api.openai.com -key "$OPENAI_API_KEY" -m gpt-realtime -n 5000 -c 500 -t 60
+
+# Through the gateway — run once with pool ON, once with REALTIME_POOL_SIZE=0
+./wsbench -host <gateway-host> -key "$LITELLM_MASTER_KEY" -m gpt-realtime -n 5000 -c 500 -t 60
+```
+
+Run the gateway with the env stand-in (`OPENAI_REALTIME_MODEL=gpt-realtime`,
+`OPENAI_API_KEY`, `LITELLM_MASTER_KEY`, `REALTIME_POOL_SIZE`, `HOST=0.0.0.0`). At
+500 concurrency over N instances, size the pool to `≈ 500 / N` per instance (64 was
+used here for 10 instances). The bench repo's README covers running 500-concurrency
+legs from a hosted multi-vCPU runner. **Never commit keys — pass them via `-key`.**

+# LiteLLM Rust integrations
+
+This directory contains Rust-native equivalents of LiteLLM integration hooks.
+The first supported surfaces are terminal custom loggers and pre/during-call
+custom guardrails.
+
+## File layout
+
+Every integration is a folder:
+
+- `mod.rs` contains the implementation, trait, runner, or adapter
+- `types.rs` contains the integration-local request, response, error, and future
+  types
+
+Do not add new flat integration files such as `custom_logger.rs`. Shared wire
+contracts that are used by multiple integrations can stay in
+`integrations/types.rs`.
+
+Call ordering and lifecycle timing live in `litellm-core/src/call_lifecycle`.
+Call-type modules, such as OCR, adapt their request and response shapes into
+that generic lifecycle runner.
+
+## CustomLogger
+
+Implement `CustomLogger` when Rust code needs to observe terminal success or
+failure events. Method names intentionally match Python `CustomLogger` names.
+
+```rust
+use litellm_ai_gateway::integrations::custom_logger::{
+    CallbackTiming, CallbackValue, CustomLogger, LogFuture, ModelCallDetails,
+};
+
+struct RecordingLogger;
+
+impl CustomLogger for RecordingLogger {
+    fn async_log_success_event<'a>(
+        &'a self,
+        model_call_details: &'a ModelCallDetails,
+        response_obj: &'a CallbackValue,
+        timing: CallbackTiming,
+    ) -> LogFuture<'a> {
+        Box::pin(async move {
+            let model = &model_call_details.model;
+            let provider = &model_call_details.custom_llm_provider;
+            let call_type = model_call_details.call_type.to_string();
+            let request_id = model_call_details.request_id.as_deref();
+            let response_object = &response_obj.object;
+            let duration = timing.end_time - timing.start_time;
+            let standard_payload = model_call_details.standard_logging_payload.as_ref();
+
+            Ok(())
+        })
+    }
+
+    fn async_log_failure_event<'a>(
+        &'a self,
+        model_call_details: &'a ModelCallDetails,
+        response_obj: Option<&'a CallbackValue>,
+        timing: CallbackTiming,
+    ) -> LogFuture<'a> {
+        Box::pin(async move {
+            let error = model_call_details.failure_error.as_ref();
+            let response_object = response_obj.map(|value| value.object.as_str());
+            let duration = timing.end_time - timing.start_time;
+
+            Ok(())
+        })
+    }
+}
+```
+
+Use `CustomLoggerRunner` to fan out terminal events to configured loggers. The
+runner is a no-op when no loggers are configured, which is the expected fast
+path for requests without callbacks.
+
+## CustomGuardrail
+
+Implement `CustomGuardrail` when Rust code needs to run pre-call or native
+during-call checks. Method names intentionally match Python `CustomGuardrail`
+entrypoints inherited from Python `CustomLogger`.
+
+```rust
+use litellm_ai_gateway::integrations::custom_guardrail::{
+    CustomGuardrail, GuardrailContext, GuardrailDecision, GuardrailEventHook,
+    GuardrailFuture, GuardrailRequest,
+};
+
+struct BlocklistedPromptGuardrail;
+
+impl CustomGuardrail for BlocklistedPromptGuardrail {
+    fn guardrail_name(&self) -> &str {
+        "blocklisted-prompt"
+    }
+
+    fn supported_event_hooks(&self) -> &[GuardrailEventHook] {
+        &[GuardrailEventHook::PreCall]
+    }
+
+    fn async_pre_call_hook<'a>(
+        &'a self,
+        _context: &'a GuardrailContext,
+        request: GuardrailRequest,
+    ) -> GuardrailFuture<'a> {
+        Box::pin(async move {
+            if request.data.to_string().contains("blocked phrase") {
+                return Ok(GuardrailDecision::Block(
+                    litellm_ai_gateway::integrations::custom_guardrail::GuardrailError::blocked(
+                        "blocked phrase detected",
+                    ),
+                ));
+            }
+            Ok(GuardrailDecision::Allow(request))
+        })
+    }
+}
+```
+
+Use `CustomGuardrailRunner::run_pre_call` for `pre_call` guardrails and
+`CustomGuardrailRunner::run_during_call` for `during_call` guardrails. A
+`GuardrailDecision::Mask` continues with modified request data.
+`GuardrailDecision::Block` short-circuits the provider call.
+
+## Current boundary
+
+These are Rust-only primitives. Python callback and guardrail adapters are a
+separate layer that should implement these Rust traits instead of changing the
+runner interfaces.
