This is reviewed directory coverage, not a census of all procurement worldwide.","Issuer status is recorded from the cited notice and never rewritten by an elapsed deadline; an elapsed deadline instead closes submissions through state=archive, deadlineState=passed and submissionsClosed. Source verification is a past check, not continuous live monitoring or an eligibility guarantee.","The base directory and state=all show issued notices, excluding status=planned. state=planned is a separate procurement-plan view; status=planned selects it only when no explicit state is supplied. Coverage totals include both issued notices and plans; issuedNotices and planned are reported separately.","Current means issuer open and a source deadline not yet passed in its stated timezone/offset, or in any civil timezone when none is stated. Archive includes terminal statuses or passed deadlines. Unknown means current eligibility cannot be established for an issued notice. A planned procurement remains planned regardless of dates and is not an open invitation to bid.","Expected invitation dates are not submission deadlines. Planned records do not receive deadline eligibility or countdowns; recorded money retains its source basis. Verify the later official invitation and amendments before bidding.","Sectors and activities require explicit reviewed procurement source evidence; no keyword, issuer-country or company-name inference and no physical well joins. Empty arrays and absent procurement remain unclassified.","A day has no assumed closing time. A local minute without an explicit UTC offset remains an unknown instant; no browser/server timezone or issuer-country timezone is inferred. Without a usable offset or timezone, deadlineState is passed only once the deadline has elapsed in every civil timezone (UTC−12:00 to UTC+14:00), upcoming only while it is due in none, and unknown in between. today is the deadline date in the stated timezone/offset.","Deadline sort is closing soonest: deadlines not yet passed first, then records without a deadline, then passed deadlines most recent first. Known instants use their UTC day and time; uncertain clocks retain the reported calendar day. On a shared sort day, known instants precede uncertain clocks. No timezone is assigned to an uncertain clock. Monetary amounts retain currency and estimated-budget/awarded-value/bid-security basis.","Grouping requires exact issuer/country/reference/URL plus matching notice metadata and summaries; unknown references/dates and different lots/amendments stay separate. Every grouped brief retains its public link.","Source dates, access/check times and Wellficent first publication/update times remain separate. Null is unknown, never zero. Preserve source attribution and source-specific reuse conditions.","The official source catalogue is separate routing information, not additional tender records or proof of open bids. Its source/country counts never add to notice coverage. Directory counts beside each source cover its issuer country, not records attributed to that website.","GET/HEAD only.
