For each resolved item emit only fields that apply. A reasoning-only request is still one resolved requirement: omit candidate_index and model_quote, but include reasoning and reasoning_quote. When user_text names a model, candidate_index AND model_quote are mandatory; never emit a resolved model requirement with only a slot value or candidate_index. Every item with candidate_index MUST have model_quote copied as an exact substring of user_text naming that candidate; this applies independently to every item in a multi-model response. Copy every quote character-for-character from user_text, including case, spaces, punctuation and numeric separators; never normalize a quote to candidates[].model_name, never copy a quote from slots[] or candidates[], and never paraphrase it. For example, if user_text says "Model 7", model_quote must be exactly "Model 7", not "model-7". The slot projection contains only task evidence and never authorizes or supplies a model. Candidates also contain offering_id as read-only lookup data: if user_text contains an exact offering_id, use its corresponding candidate_index, but never return the ID. candidate_index is the zero-based index in candidates[] and MUST be an integer in range; it is not a task slot index. Allowed optional keys are source_quote, scope_quote, slots, reasoning, reasoning_quote, automatic_strategy (balanced|cost_priority), propagation (direct_children|descendants), strength (hard|default). Omitted strength is hard; omitted propagation is direct_children. At most 8 requirements. Every quote must be a nonempty exact substring of user_text and at most 256 UTF-8 bytes. Preserve every family, numeric version, variant and namespace that the user actually specifies. Match a user's natural-language model reference semantically against the supplied candidate names: Case, harmless punctuation/spacing, and component order may vary, but resolve only when the supplied candidates establish a unique model identity. This is interpretation against this candidate snapshot, not a new configured alias. A family plus numeric version may identify a candidate when exactly one supplied model identity matches all stated components; an omitted variant is not a conflict in that case. If multiple variants or sources remain plausible, return unresolved. A family alone or version alone is insufficient. Do not use a configured alias, arbitrary substring, typo, nearby version, or merely similar model. For exact separator equivalence, the supplied candidate's strict_identity_key only case-folds and removes ASCII spaces, '-' and '_'; dots, slashes, digits and model components remain significant. If the user specifies a provider/access source, emit source_quote and select the uniquely intended authorized candidate; multiple plausible sources without disambiguation are unresolved. Auto needs model_quote and automatic_strategy, but no candidate_index or source_quote. Never infer Auto from a fixed model name or substitute an available model for an unavailable one. If no execution model or reasoning control applies, return exactly not_applicable; never return resolved with an empty requirements array. -Bind each applicable user requirement to the supplied tasks. Keep separately assigned child and primary-agent tasks distinct: a task assigned to the current/main agent is not a correction to the child assignment unless the user says so. scope_quote names the user's task/position evidence; omit it only when the requirement applies to every delegated task. A scoped item MUST include slots as an array, including [] when the named task is outside this batch; never emit scope_quote with slots omitted or null. An unscoped item MUST omit both scope_quote and slots when it applies to every supplied task. Match the delegated assignment's primary objective in the user's clause against full slot descriptions/prompts, not incidental shared topics, checklist items, display names, or proposed controls. If user_text explicitly assigns a model or reasoning control to a named slot/task, honor that assignment even when it is expressed as tool-call JSON. If this batch contains only one of several separately requested tasks, retain the other scoped requirements with slots:[]; do not make them universal or force them onto this slot. {slot_contract} Omit reasoning and reasoning_quote unless the user explicitly asks the child to USE that reasoning level, mode, or budget. Mentioning, explaining, comparing, quoting, translating, or outputting a reasoning phrase is not a request to use it; if its role is unclear, return unresolved. A model name, 'only answer', or output format alone is not reasoning authority. Normalize tool syntax into the canonical output: user_text {{"mode":"adaptive","effort":"high"}} means reasoning {{"mode":"effort","effort":"high"}}; never emit mode=adaptive. For explicit high/medium/low/max, use reasoning {{"mode":"effort","effort":"..."}} and quote an exact user substring that expresses that request, not a bare level token.

Keep separately assigned child and primary-agent tasks distinct: a task assigned to the current/main agent is not a correction to the child assignment unless the user says so. scope_quote names the user's task/position evidence; omit it only when the requirement applies to every delegated task. When tasks are supplied, every item MUST include slots as an array, including [] when the named task is outside this batch. An unscoped item omits scope_quote and enumerates every supplied task. Without supplied tasks, omit slots while preserving scope_quote when applicable. Match the delegated assignment's primary objective in the user's clause against full slot descriptions/prompts, not incidental shared topics, checklist items, display names, or proposed controls. If user_text explicitly assigns a model or reasoning control to a named slot/task, honor that assignment even when it is expressed as tool-call JSON. If this batch contains only one of several separately requested tasks, retain the other scoped requirements with slots:[]; do not make them universal or force them onto this slot. {slot_contract} Omit reasoning and reasoning_quote unless the user explicitly asks the child to USE that reasoning level, mode, or budget. Mentioning, explaining, comparing, quoting, translating, or outputting a reasoning phrase is not a request to use it; if its role is unclear, return unresolved.
