Load when handling untrusted tool results, guarding a write tool, or scoping what an agent remembers.\n---\n\n# Trust and safety rules\n\n`commerce_common\u002F` is `commerce-common\u002Fcommerce_common\u002F`, `shopping_agent\u002F` is `shopping-agent\u002Fcore\u002Fshopping_agent\u002F`, and\n`merchant_agent\u002F` is `merchant-agent\u002Fcore\u002Fmerchant_agent\u002F`; `docs\u002Fsafety.md` lists the same rules. A rule inside a tool\ncall holds on all three paths, which share one executor (commerce-architecture); rules 10 and 15 name the paths they run\non. Merchant staging, guardrails, approval, and marketplace posture are in commerce-merchant-operations.\n\n## Fence third-party content\n\n1. Every tool result from catalog, review, policy, order, metric, message, or web content goes through\n   `Fence.fence_payload` (`commerce_common\u002Ffencing.py`): NFKC-normalized, invisible and control characters removed, fence\n   markers, forged turn markers, and special tokens replaced, wrapped in the role's label, and cut at `max_fenced_chars`.\n   The executor's `_fenced` applies it to every handler.\n2. The label and the notice are per-role constants (`STOREFRONT_FENCE` in `shopping_agent\u002Ffencing.py`, `MERCHANT_FENCE` in\n   `merchant_agent\u002Ffencing.py`); the notice appears once, in the static prompt, with nothing untrusted in it.\n3. The per-request block (profile, cart, memory facts, page, store context) sits inside the same fence after the cache\n   breakpoint (`build_dynamic_context` in each role's `prompt.py`); backend context blocks have their own cap.\n4. A model-supplied result count is clamped to `max_search_results` (`clamp_limit` in `commerce_common\u002Fexecution.py`).\n\n## Gate writes on provenance and caps\n\n5. A cart write accepts only ids in `ShoppingSessionState.seen_products`, filled by the session's catalog and order reads\n   (`check_provenance` and `remember_order_items` in `shopping_agent\u002Fgates.py`); update and remove also accept a line\n   already in the cart. Merchant staging accepts only ids in `seen_listings` and `read_listings`, apply and discard only\n   ids in `seen_changes` (`merchant_agent\u002Fgates.py`; commerce-merchant-operations).\n6. `max_quantity_per_item` caps the line after the write and `max_cart_lines` the cart, under a session lock\n   (`gated_add_to_cart` in `shopping_agent\u002Fgates.py`; caps in `shopping_agent\u002Fconfig.py`). The lock is per process, so\n   `StorefrontBackend` cart methods enforce them too; eligibility, pricing, and inventory are the backend's in both roles.\n7. Nothing in either interface charges or places an order: `checkout` renders the cart (`enrich_checkout` in\n   `shopping_agent\u002Fenrichment.py`) and the host completes it; post-purchase care is reads, with no cancel or refund tool.\n8. Provenance lives on the session state (`ShoppingSessionState`, `MerchantSessionState`), saved with the session when\n   the request or turn ends (`SessionStore` in `examples\u002Fdemo_common\u002Fsessions.py`, a versioned state document beside the\n   transcript), so a request on another process loads it. Each map keeps its newest `PROVENANCE_CAP` records (`remember`\n   in `commerce_common\u002Ftypes.py`); a dropped id needs a fresh read.\n9. A component is validated, its products, orders, metrics, or changes are joined from those records, and ids without\n   provenance are dropped and reported (`run_presentation` in `commerce_common\u002Fpresentation.py`; each role's\n   `enrichment.py`; commerce-ui-tools).\n\n## Ground the answers that are figures or terms\n\n10. A terms question, an order question, or an unseen product id (`GROUNDING_RULES` in `shopping_agent\u002Fgrounding.py`), or\n    a performance question or an apply request with nothing staged (`merchant_agent\u002Fgrounding.py`), starts from the\n    matching read: `first_forced_tool` in `commerce_common\u002Fgrounding.py` picks it, the Messages API runtimes force it with\n    `tool_choice`, and the SDK runtimes prefetch it when the rule has a prefetch form (`ground` in\n    `commerce_common\u002Fagent_sdk.py`; the terms rule has none); the hosted path has the prompt only.\n11. The lexicons are config tuples (`policy_intent_terms`, `order_intent_terms`, `product_id_patterns`, `metrics_intent_terms`,\n    and their cues); a deployment appends its own words, a gate flag turns a rule off, and neither changes prompt bytes.\n\n## Hold identity on the server\n\n12. Session start binds the authenticated principal to an unguessable session id; later requests carry only that id, and\n    routes read the principal from the record (`SessionStore.start` and `session_dependency` in\n    `examples\u002Fdemo_common\u002Fsessions.py`). No request field or tool argument names a user, merchant, or operator; the MCP\n    servers take the principal from their environment, a production server from its request.\n13. Whether the principal owns a record (order, ticket, listing), and whether the step a call depends on has\n    happened, is the backend's check against its store; an id having provenance does not make it theirs or ready.\n\n## Bound what is remembered\n\n14. Every fact on both write paths (`save_memory` and post-turn extraction) passes `validate_fact` in\n    `commerce_common\u002Fmemory.py`: key of at most 64 characters, value of at most 200, one of the three `MemoryCategory`\n    values, and the `MemoryWriteFilter`, which refuses identifier-shaped values by default; `memory_blocked_patterns`\n    adds patterns, and a filter with `checks` replaces it (`MemoryRuntime.build`).\n15. Extraction reads the last exchange's user and assistant text (`transcript_text` in `commerce_common\u002Fturn.py`), and\n    `extract_and_store` drops its batch when the subject was purged meanwhile; the Messages API runtimes run it\n    (`update_memory`), the SDK host calls the runtime, and the hosted path writes through `save_memory` only.\n16. `memory_retention_days` (`with_retention`), `MemoryStore.delete_fact`, `MemoryStore.clear`, and `enable_memory` hold\n    on every path without changing prompt or tool bytes; the examples expose read and delete routes\n    (`install_memory_routes` in `examples\u002Fdemo_common\u002Fmemory.py`), and `clear` belongs in account deletion.\n17. The subject is the shopper's `user_id` or the operation's `merchant_id` (`memory_subject` in each role's `executor.py`).\n\n## Refuse in the result, and keep the surface fixed\n\n18. A held call returns a normal result naming its gate (`ToolOutcome.held` in `commerce_common\u002Fstreaming.py`; the host's\n    `tool_result` event carries `status: blocked`), a failure returns an error result, and `execute` never raises.\n19. The tool list is a function of the config: `enable_web_search` (default off) adds the tool, the SDK runtimes allow-list\n    the registered names, and the manifests enable tools one by one.\n20. The reference MCP servers bind to loopback unless an environment variable states that an authenticating gateway is in\n    front (`enforce_local_only_bind` in `commerce_common\u002Fmcp_server.py`).\n\n## Two rules for adversarial evals\n\n- Poisoned listings, reviews, and messages live in eval fixtures merged in for a run, outside demo and catalog data.\n- Every refusal case has a should-serve counterpart in the same niche, so a suite catches over-refusal too (commerce-evals).\n",{"data":38,"body":39},{"name":4,"description":6},{"type":40,"children":41},"root",[42,51,110,117,243,249,483,489,593,599,634,640,852,858,938,944],{"type":43,"tag":44,"props":45,"children":47},"element","h1",{"id":46},"trust-and-safety-rules",[48],{"type":49,"value":50},"text","Trust and safety rules",{"type":43,"tag":52,"props":53,"children":54},"p",{},[55,62,64,70,72,78,79,85,87,93,94,100,102,108],{"type":43,"tag":56,"props":57,"children":59},"code",{"className":58},[],[60],{"type":49,"value":61},"commerce_common\u002F",{"type":49,"value":63}," is ",{"type":43,"tag":56,"props":65,"children":67},{"className":66},[],[68],{"type":49,"value":69},"commerce-common\u002Fcommerce_common\u002F",{"type":49,"value":71},", ",{"type":43,"tag":56,"props":73,"children":75},{"className":74},[],[76],{"type":49,"value":77},"shopping_agent\u002F",{"type":49,"value":63},{"type":43,"tag":56,"props":80,"children":82},{"className":81},[],[83],{"type":49,"value":84},"shopping-agent\u002Fcore\u002Fshopping_agent\u002F",{"type":49,"value":86},", and\n",{"type":43,"tag":56,"props":88,"children":90},{"className":89},[],[91],{"type":49,"value":92},"merchant_agent\u002F",{"type":49,"value":63},{"type":43,"tag":56,"props":95,"children":97},{"className":96},[],[98],{"type":49,"value":99},"merchant-agent\u002Fcore\u002Fmerchant_agent\u002F",{"type":49,"value":101},"; ",{"type":43,"tag":56,"props":103,"children":105},{"className":104},[],[106],{"type":49,"value":107},"docs\u002Fsafety.md",{"type":49,"value":109}," lists the same rules.
