A working prototype of the pipeline: recording → transcript → persistent knowledge base → content draft → safety gate → nurture placement → human approval. Built to make that architecture provable rather than only described. What follows is real output from a real program, not mockups.
⚠ Demo only — brand, transcript and figures below are fictional placeholdersEach brand's knowledge base is loaded once and retrieved by relevance against the new recording — not the whole library, every run.
New content fills an empty slot in the journey, proposes replacing weaker evergreen content, or routes to a broadcast lane — never blindly appended.
Every claim is checked against the source material. Anything unsourced — including a specific number that doesn't appear anywhere in the transcript or knowledge base — is blocked before a human ever sees it for approval.
The pipeline only ever writes to a pending-review queue. A separate, deliberate approval step is required to publish anything, and it refuses to approve a blocked draft.

[case-study] We bought it below market value because it needed a full rewire and a new kitchen. [case-study] We budgeted eighteen thousand pounds for the refurb and finished under budget. [case-study] The tenant moved in within two weeks of completion. [problem-awareness] A lot of new investors underestimate how long a rewire takes, so I always tell people to add two weeks buffer to your builder's estimate. [objection-handling] Another thing worth mentioning is that landlords in this area keep asking us about deposit protection rules, and that's something we handle for every tenancy we manage.

PASS (1) We sourced a three-bed terrace below market value because it needed a full rewire and a new kitchen. The refurb budget was eighteen thousand pounds and the project finished under budget. The tenant moved in within two weeks of the refurb completing. Investors who underestimate rewire timing often miss their target completion date, so we always add a two-week buffer to the builder's own estimate. PASS (1) Landlords we work with regularly ask about deposit protection rules. Every tenancy we manage has its deposit registered with an approved scheme, and we handle the paperwork so the landlord doesn't have to track it themselves.

Identical input, except the drafting step invented one plausible-sounding, unsupported claim: "This refurbishment achieved a 40% return within six months of completion." That figure appears nowhere in the transcript or the knowledge base.
