## Query format

\`queries\` is an array of 1–10 company-search query objects with union semantics: an issue matching any query belongs to the card. Prefer one narrow query; add another only for genuinely distinct populations. Each object accepts:

- \`scope\`: always \`"issues"\`.
- \`q\`: optional short free text, only for concepts no structured filter covers. Never paste the whole prompt into it.
- \`status\`: array of ${ISSUE_STATUSES.map((status) => `\`${status}\``).join(", ")}.
- \`priority\`: array of ${ISSUE_PRIORITIES.map((priority) => `\`${priority}\``).join(", ")}.
- \`assigneeAgentId\` / \`assigneeUserId\`: one resolved assignee id.
- \`projectId\` / \`labelId\`: one resolved UUID each. Resolve names with \`GET /api/companies/${card.companyId}/projects\` and \`GET /api/companies/${card.companyId}/labels\`; never put a name in an id field. Use separate query objects for multiple projects or labels.
- \`updatedWithin\`: a bounded window such as \`24h\`, \`7d\`, \`4w\`, or \`3m\`. Add it whenever the prompt implies recency (recent, this week, lately, current).
- \`sort\`: \`relevance\`, \`updated\`, \`created\`, or \`priority\`.
- \`limit\`: 1–50, normally 20. \`offset\`: 0.

Preserve the prompt's intent; do not broaden it. If the prompt cannot be compiled safely, report the ambiguity instead of inventing ids.

Example \`PUT /api/status-cards/${card.id}/query\` body:

\`\`\`text
{"queries":[{"scope":"issues","q":"launch","status":["in_progress","blocked","in_review"],"updatedWithin":"7d","sort":"updated","limit":20,"offset":0}],"title":"Launch work updated this week","changeSummary":"Compiled the prompt into one recent active-work query.","generationIssueId":${JSON.stringify(exampleGenerationIssueId)}}

${UNTRUSTED_PROMPT_RULE}

## Interest prompt

${untrustedPromptBlock("interest-prompt", card.interestPrompt)}

## Required write-back sequence

1. \`PUT /api/status-cards/${card.id}/query\` with \`queries\`, an auto-title, a non-empty \`changeSummary\`, and \`generationIssueId\`.
2. Execute the compiled scope with \`GET /api/status-cards/${card.id}/dry-run\`, then write the first full Markdown summary with \`PUT /api/status-cards/${card.id}/summary\` (\`markdown\`, \`title\`, a non-empty \`changeSummary\`, the same \`generationIssueId\`, and the model id). Do not create or wait for a second task.

Both writes must happen from this assigned issue run.
