    2026-10-05-p4-quality-run

    Quality run to P4: claim array, source dates, present-tense audit. Circl was dismantled from May 2024 with components stored for reuse and no new site named (Zuidas, Oct 2024). The 2019 Madaster item gave eight MRA municipalities certificates for being 'well on their way' to a passport for one building each — not passports, and not a city ledger. Scope is a set of pilots, not citywide.

    2026-08-21-unsourced-text-correction

    Removed or softened wording that no listed source carries, after reading every source while preparing the claim ledger. The location (Zuidas), the superlative ('Madaster's first') and the year 2017 are gone: none of the three sources carries them.
