Root lane closed9September2026. Read public official notice and guidance; no tender response, account, recipient contact or underlying content access. This establishes a prospective purchase and a documented recommendation, not the accounting destination of TAT's government support.
[Sell2Wales notice SEP653567](http[local research file] published2September2026, identifies Home Office and TAT in a UK5 notice for a pilot covering discovery, analysis and bulk referral of terrorist content to technology companies. OCID ocds-h6vhtk-06efa9; supplier PPON PQQZ-1663-NWMN. The contract is explicitly pending, with estimated signature14September2026 and term14September2026–15March2027. It displays GBP192,000 excluding VAT and GBP240,000 including VAT. These displayed amounts are unreconciled here, not payment evidence. Its direct-award justification invokes prototype/development services. The conflict-of-interest document is marked unpublished; no conclusions about its contents follow.
This government-hosted record has greater evidentiary value for stage than an aggregator's Awarded label. It does not establish an executed agreement, actual delivery, the legal recipient's company number, specific target selection rights, OHF–QuantSpark subcontract terms or a project allocation. Its future dates cannot explain FY2025 invoices.

No download form or unpublished attachment was pursued.
The [Home Office guidance dated15February2024](http[local research file] explicitly recommends TCAP and the Knowledge Sharing Platform where applicable. It encourages proportionate customer-identification checks, contractual enforcement, reporting/appeals and service-specific restrictions across infrastructure types. It also says the guidance creates no legal obligation and targets unlawful terrorism-related material. Its discussion of separate statutory/police-notice duties is not a demonstration that any particular TAT alert triggers those duties. Recommendations cover providers regardless of location, while existing laws still matter.
This establishes a public endorsement and intended implementation route. It does not establish a compulsory TCAP subscription, a universal filtering requirement, actual supplier deployment or government direction of particular TCAP classifications. Advice to consider measures and legal compulsion must remain separate in the map.

Initial combined output truncated; missing introductory scope was reread separately. Statutory discussion is attributed to this dated guidance, not a fresh complete current-law opinion.
[The D3 procurement index](http[local research file] reports an Ofcom purchase of twelve-month TCAP access, with a GBP34,000 contract value, a3March2026 signing date and23March2026–23March2027 period. It identifies FindTender032552-2026. That original URL returned a nonretryable web-reader error and was closed; a scoped search found no alternate official Ofcom record. The actual official notice, agreement, permitted access scope and payment are unacquired. Do not convert this secondary listing into a proved government database-access right or a contradiction of the older TCAP FAQ. No database access was attempted.
QuantSpark's public Digital Marketplace listing also appeared in search. That is a supplier offer, not evidence of a buyer's call-off or funding TAT; its detailed contract was not acquired/read in this lane. Broad policy reports and consultation responses appeared but were not opened into new branches.
The useful outstanding records are the Home Office's eventual signed pilot agreement and performance/selection clauses, a verified Ofcom instrument defining purchased access, and an actual project-to-supplier allocation or subcontract term. A public procurement label cannot bridge these on its own. Canadian contribution disclosures and the two companies' accounts are separate lanes of this bounded run. All root acquisition has stopped for the combined forest once those lanes close.
