Knowledge changes. Kofa tells you when it matters.

What was true yesterday may not be true today. Markets change, policies change, people move. Most research ends when the report is delivered — Kofa keeps the knowledge, and keeps track of when it may need another look.

Capture it → Date it → Monitor it → Refresh it. Your knowledge doesn't silently go stale.

01 · Every record carries its history

Kofa tells you where your knowledge came from.

A decision asset isn't just a document. Its knowledge carries its history — what was learned, who said it, when it was learned, where it came from, and what happened afterwards. So when someone asks "can we still rely on this?", you don't have to guess. You can see the record.

The record keeps its history attached.

What was learnedThe finding or claim.
Who said itThe practitioner or source.
When it was learnedThe engagement and capture date.
Where it came fromThe underlying evidence and conversation.
What happened afterwardsReviews, updates and newer evidence.
02 · The clock

Every record carries its date. The date decides.

Kofa watches for knowledge that may be aging — not everything needs checking at the same time. Each record moves through honest states, and the original is never rewritten: it stays, with its date, linked to anything newer.

The clock Six states

CurrentSafe to cite as of its capture date. Refresh available if the world moves.Nothing to do
Review dueThe expected review date has arrived — not necessarily wrong, it simply needs confirmation.Verify →
Change suspectedA newer engagement contradicts a claim here, or a signal moved — Kofa flags it, it never decides the truth changed.Review changes →
StaleOutside its acceptable currency window and not reconfirmed.Verify →
SupersededA refresh produced a newer record — the original stays citable, linked to its history.View the delta →
ArchivedDeliberately retained as history — it no longer reads as current.

The state is derived from the record's own fields — capture date, knowledge type, and your organisation's currency policy. It is never stored, and never a universal rule.

A flag is a signal — never a verdict.

03 · How the clock moves

Not everything needs checking at the same time.

Some knowledge changes quickly; other knowledge stays useful for years. The clock runs per type — regulatory knowledge expires faster than operational practice — and a practitioner check resets it: the as-of moves to the check date.

The clock is per type

Each knowledge type has its own currency period, owner and review lead — the next-review date derives from type + as-of, and review begins before the date arrives.

Time

The cheapest, most honest detector — assets age on a schedule, and every record carries its date.

Events

Policy and market monitoring — gazettes, circulars, reforms — plus the coordinator network on the ground.

The practitioner

Ask the same person “is this still true?” — a check, not a new engagement.

Kofa flags a potential change — it never decides the truth changed. The human decides whether the knowledge is actually obsolete.

04 · When a record needs another look

A currency warning leads to action, not another dead report.

When a record needs review, Kofa connects the warning to the next engagement — you don't lose the old answer, you gain the new one.

Refresh this knowledge
The delta

Old knowledge isn't destroyed. It's replaced with a delta.

When a refresh produces a newer record, the original stays citable — linked to its history, with the delta stating what changed: no longer holds · gone.

Version chain

Old versions are never destroyed — each states what changed.

v1Original capture
v2Refresh — the practitioner re-ran the question
v3Re-confirmed by the practitioner

Practitioner check

The fastest — the same person confirms what still holds.

Delta refresh

A shorter session: what changed since we spoke, what holds, what’s gone — 24–48 hours.

Policy monitor

A subscription that flags against gazettes, circulars and reforms.

A refresh is not a new engagement — the same brief, the same practitioner, "what changed since we spoke?" A shorter session, a smaller fee, 24–48 hours.

05 · Knowledge that gets better with use

Don't just store what you learned. Know when to trust it.

Research should not become a pile of old documents. It should become a living body of knowledge — captured, dated, monitored, and refreshed as the world moves.
