Get Deal Memo

Return one memo for a deal, with signed PDF download links.

Returns both published memos and unpublished drafts; status and published_at disambiguate. pdf_url is null when no rendered variant exists for the requested quality (common for drafts that have never been previewed). Authorizes the deal first (404 when inaccessible), then runs the single-row memo query through the DOCUMENT_GENERATION_STRUCTURE READ policy so a memo this caller can't actually read (e.g. not shared into their vault when deal-read came via shared vault) is invisible — same 404, same shape as a missing memo. quality selects which rendered variant pdf_url points at (default original); pdf_versions lists every variant that exists for this memo (may be empty for unrendered drafts).

Where the deal documents/vaults surface is enabled for the caller, the memo is tagged with vaults — the {id, type, title} of the vaults it lives in, scoped to the caller's visible vaults (empty when none are visible); omitted otherwise so vault names don't surface ahead of that launch.
