+"""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:
+

+    (``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``).

+    :class:`datetime.datetime` (:func:`parse_iso8601`).
+
+Keeping these in one module means a future change (new Greptile output

+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

+and **open a fresh PR**, or to comment `@agent-shin reconsider` on the

+"""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

+name: Agent Shin — reconsider
+
+# Comment-trigger workflow: when the PR/issue author (or an internal
+# collaborator) comments `@agent-shin reconsider` on a CLOSED PR/issue,
+# Agent Shin re-runs LLM-judge triage on the current title+body and:
+#
+#   - on PASS:  posts a "re-evaluated and reopened" comment + reopens.
+#   - on FAIL:  posts a "still missing X" comment and leaves it closed,
+#               so the contributor can iterate again.
+#
+# This exists because GitHub does NOT let an external (non-write-access)
+# OSS contributor reopen a PR/issue closed by a bot or maintainer. Without
+# this comment trigger, a contributor whose PR Agent Shin auto-closed
+# would have no path back into the review queue except opening a fresh PR
+# (which loses the original PR's history). The bot, on the other hand,
+# has write access via GH_TOKEN and can reopen on their behalf.
+#
+# DRY-RUN BY DEFAULT — gated on `vars.AGENT_SHIN_ENABLED == 'true'` just
+# like the other Agent Shin workflows. The workflow also gates on the
+# commenter being either the PR/issue author or an internal collaborator

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
+When you fix violations gated by `ruff-strict-budget.json`, `type-discipline-budget.json`, or `basedpyright-code-budget.json`, run `make lint-budget-update` and commit the lowered limits so the ceilings ratchet down instead of leaving stale headroom. It measures the working tree, so it must contain exactly the fixes you're committing
+
+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
+
+Every lint or type suppression must name the exact rule inside brackets and carry a reason comment, e.g. `# pyright: ignore[reportArgumentType]  # stubs lack async overload` or `# noqa: TID251  # <reason>`. `# type: ignore` is banned (LIT009): pyrightconfig.json sets `enableTypeIgnoreComments` to false, so it silently does nothing
+
+Commit and push your work when you're done without asking
+
+When referencing or running models (coding, QA'ing, writing docs, writing tests, etc.), use the latest model in that model family unless otherwise specified; treat your training knowledge, memories, configs, and tests as stale, and determine the family's latest with model_prices_and_context_window.json or the web
 
 If you're an internal contributor, when creating a new PR, the typical flow is to branch off litellm_internal_staging and create a branch prefixed with litellm_. Do not create a branch prefixed with claude/ and generally do not have / in your branch names
 
@@ -48,10 +61,26 @@ When working on a PR, keep the PR description in sync with new commits being mad
 
 Monkeypatching attributes of a class to do testing is an anti-pattern. Prefer dependency-injecting things into classes. That way, at unit test time, you can pass a mocked dependency in
 
-Do not put names of customers or customer company names in code, PRs, and issues. The codebase is public
+Do not put names of customers or customer company names in code, PR descriptions, issue bodies, etc. This means never mention literally any company name. Especially if you're about to say a sentence mentioning that the reason the PR exists was a feature/model/bug fix/etc. requested by a company. 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. 
 
 CI supply-chain safety: Never pipe a remote script into a shell (`curl ... | bash`, `wget ... | sh`); download the artifact to a file, verify its SHA-256 checksum, then install. Pin every external tool to a specific version with a full URL (not `latest` or `stable`). Verify checksums for all downloaded binaries, using the provider's official `.sha256` / `.sha256sum` sidecar when available. These rules apply to every download in CI
 
+Follow these coding conventions for new/updated code (a three-line fix in a legacy file shouldn't trigger huge drive-by refactors):
+
+- Composition over inheritance
+- Never-nester: early returns over deep nesting
+- Don't throw; model failures as values (One function (e.g., raise_public) maps error union to existing public exception contracts via exhaustive match + assert_never)
+- No mutation; don't reassign variables, global or local. Instead of mutable lists and dicts, prefer tuples, frozen dataclasses (with slots=True), etc.
+- Use dependency injection
+- Fully typed; no `Any` or coarse types like `dict[str, Any]` or just `dict`. Every function parameter must be strongly typed
+- Use tagged unions + match
+- No monster files or god objects
+- No file sprawl: deliberate file and folder structure
+- Standard over hand-rolled: use the official SDK or a library where one exists; where none does, follow industry standards instead of inventing local conventions
+- API-fragmentation-aware: when logic must branch on which API surface produced or consumes data (e.g. chat completions vs Anthropic Messages vs Responses API shapes), proactively look for an existing shared helper (e.g. `litellm_core_utils/prompt_templates/factory.py`) before writing per-surface parsing in the new module; if none exists, add one there instead of duplicating the same format-detection logic in every new guardrail/integration
+
+Follow conventional commits for commit names and PR titles

+-- Converts an existing LiteLLM_SpendLogs table into a native Postgres
+-- range-partitioned table keyed on "startTime".
+--
+-- Why: at high request volume, retention via DELETE leaves dead tuples that
+-- autovacuum cannot reclaim quickly enough, so the table keeps growing on disk
+-- (seen at 450GB+ after ~1 month). With partitioning, retention drops whole
+-- partitions, which is instant and returns disk to the OS immediately.
+--
+-- This is an opt-in, manual operation. The default LiteLLM schema is NOT
+-- partitioned, so existing installs are unaffected until you run this.
+--
+-- IMPORTANT
+--   * Test on a staging copy first and take a backup.
+--   * Postgres cannot convert a populated table to partitioned in place, so this
+--     renames the old table aside and creates a fresh partitioned table.
+--   * The partition key ("startTime") must be part of the primary key, so the
+--     PK becomes composite ("request_id", "startTime"). LiteLLM's write path uses
+--     INSERT ... ON CONFLICT DO NOTHING, which is compatible with this.
+--   * Choose a partition granularity ("day" is the recommended default for
+--     high-volume tables) and keep it consistent with SPEND_LOG_PARTITION_INTERVAL.
+--
+-- After running this, enable the feature and set a retention period in
+-- proxy_config.yaml:
+--   general_settings:
+--     use_spend_logs_partitioning: true
+--     maximum_spend_logs_retention_period: "30d"
+-- The spend-log cleanup job then verifies the table is partitioned and reclaims
+-- disk by dropping expired partitions instead of deleting rows. It also
+-- pre-creates upcoming partitions on each run. To roll back, see
+-- db_scripts/unpartition_spend_logs.sql.

-# 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">

-guardrails:
-  - guardrail_name: "xecguard-guard"
-    litellm_params:
-      guardrail: xecguard
-      mode: "pre_call"
-      api_key: os.environ/XECGUARD_API_KEY

-      default_on: true                              # Optional
-```
-
-### 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
-      policy_names:
-        - Default_Policy_HarmfulContentProtection
-        - 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.
