Evidence: Bounded tag page resource checks
Date: 2026-10-30 UTC
Environment: Local PHP 8.1.2 CLI, SQLite; fresh subprocess per sample; synthetic fixtures, not QDB host
Dimensions: 2 KiB bodies, 1 KiB previews, fixed 25 selected rows; 24 populated generated tags
Candidate rows examined: Not instrumented; tag membership predicates may examine the corpus. Hydrated rows are bounded independently. No claim of constant CPU or I/O.
Large record: Exact 16 MiB canonical source parsed before inserting its body; one such record among 25. Peak includes fixture preparation; tag template preserves its existing preview presentation. Not a guarantee for 25 simultaneous maximum-size records or all HTML-escaping distributions.
