TACITUS builds Context Capsules— knowledge objects that carry your sources, your situation, and your experts’ reasoning into AI work. Every claim has a receipt. Every judgment has an author.
Built for policy desks, analysts, mediators, researchers — any team whose documents must survive scrutiny. The model generates; the capsule lets you verify.
Every claim has a receipt.
Claims, commitments, and events trace to source text — paragraph, line, timestamp — with a trust tier attached.
src-042 · ¶3 · T2 · corroboratedTwo clocks, kept honest.
What happened and when you learned it are tracked separately, so analysis never quietly rewrites its own past.

Expert heuristics, methods, and traps travel inside the capsule — reviewed, attributed, and inspectable.

Scroll · the case file
Watch one diplomatic cable move through the full TACITUS engine. Each act builds on the last, and the analyst dashboard on the left shows exactly what was extracted at each step.
Raw source
A cable lands
A diplomatic cable arrives in the inbox: 9 paragraphs, 612 words, 4 referenced annexes. No structure, no provenance markers, no temporal order — and somewhere inside it, one quiet contradiction of last week’s reporting that a tired reader will miss.
Extract
Proposals · models suggest, never write
The engine reads the prose and proposes typed records: actors, claims, denials, commitments, escalation signals — every one bound to its exact source span with a confidence score and a hash-addressed receipt. Disagreement is preserved as data. Nothing is promoted yet; these are proposals awaiting a named human gate.
Order in time
Two clocks · Allen-13
Every claim gets two timestamps — when it happened, when this desk learned it — so the analysis can never quietly rewrite its own past. Episodes lock into Allen-13 interval relations: the offensive OVERLAPS the talks; the rejection MEETS the deadline. “What did we know on the 14th?” becomes a query, not an argument.
Compose the capsule
Review gates · nine layers · sealed
An expert promotes, caveats, or rejects each proposal — decisions recorded forever. The compiler then assembles the capsule deterministically: evidence at the bottom, claims with trust tiers, the graph, both clocks, the reviewer’s open questions — and the contradiction, kept as an explicit red edge. Same inputs, same bytes, one hash.
Cited memo
PRAXIS · the agentic workbench
With the capsule attached, PRAXIS drafts the SITREP under its contract: T1 asserted, T2 attributed, T3 hedged, the dispute surfaced in line. The margin names which expert device shaped each judgment. Every paragraph carries receipts; every open question is visible. The analyst argues with the model — not the other way round.

On 12 March 2026, the Government of Nordalia issued a démarche
through its Ministry of Foreign Affairs suspending negotiations with the
Democratic Reform Movement (DRM) and citing repeated ceasefire violations near
the 4.2-km demarcation line. The DRM rejected the breach allegation the same day,
characterising the movement as administrative reposition under §4 of the Framework.
Both parties confirmed their commitment to continued dialogue, with the DRM linking
progress to release of detained political negotiators on or before 18 March.

Headline.Nordalia suspended bilateral negotiations on 12 Mar[doc-042 ¶2] citing alleged ceasefire violations near the 4.2-km demarcation line[doc-042 ¶3]. The DRM rejected the breach allegation the same day[doc-044 ¶1] and characterised observed movement as administrative reposition under §4 of the Framework[doc-044 ¶3, art-04].
Contradictions surfaced.The model registers a direct contradiction between the ‘violation’ claim and the DRM denial within the same 24-hour window[edge-c1↔e2]. Verification scope remains contested under Article 4.
Commitments tracked. Both parties confirmed continued dialogue[doc-042 ¶5; doc-044 ¶4]. The DRM conditioned progress on release of detained political negotiators on or before 18 Mar[doc-044 ¶5].
Open. Verification mechanism for the 5-km halt unspecified; reciprocity clause requires Article 4 cross-reference.
case-nordalia-2026-03 · doc-042Inside a capsule
Nine layers, separated on purpose: evidence at the bottom because nothing may exist without a receipt; the ontology and graph in the middle so meaning is typed and queryable; expert reasoning and the runtime contract on top — the layers that tell an agent how to think here, not just what is known.
When an agent attaches a capsule it inherits the whole stack: it cites by trust tier, keeps both clocks, applies the expert’s devices by name, and refuses to smooth over a dispute — because the object it is reasoning from won’t let it.

Open format · open rails
A capsule compiles to whatever your agent already speaks. What no rail carries on its own — receipts, trust tiers, review gates, two clocks — is what TACITUS builds on top.
TCGC is our open benchmark for grounded reasoning over typed knowledge. The corpus and methodology are public today; scores appear here when runs are real — never placeholder numbers.

Built for serious knowledge work
Options memos and assessments with receipts a principal can check.
Commitments, contradictions, and escalation logic — attributed, not vibes.
A situation picture that keeps two clocks and never rewrites its own past.
Legal, risk, regulatory affairs, investigations — wherever “source?” is the first question.
Why us
Built by practitioners who spent a decade producing analysis for institutional decision-makers. TACITUS is named for tacitknowledge — what experts know but can’t easily tell — and for the historian who showed how to write it down anyway.

INPUT · policy text
Ceasefire allegations, humanitarian access, guarantor pressure.
The Ministry of Security alleged on 18 April that the Northern Coalition violated the ceasefire near Kalo Bridge. The coalition denied responsibility and reaffirmed its written commitment to keep the southern corridor open. The international mission warned that aid access depends on a 72-hour notification window, while both parties need credible verification before the next donor conference. The government is framing the incident as proof the coalition cannot be trusted.

GRAPH STATS · typed output
Every node is bound to the source span it came from. Every edge is typed. Every claim is auditable back to the input.
Extraction is not the final answer. It is the grounding layer: raw policy text becomes a typed graph; the graph becomes a brief the analyst can inspect, edit, and challenge.
Short, technical, citation-bearing essays. AGON and KAIROS internals. How mediators and policy analysts think. Bi-temporal honesty. Why generic LLMs break on conflict. Every note has a TL;DR, sources, and a specific problem it answers.
Browse Notes by TACITUSFrontier models made drafting cheap; checking stayed expensive. Citation is not verification — institutions run on warrant. What verified context looks like as a data structure, and why the property appreciates as models improve.
What a source said, what an analyst concluded, when each became known, and which method produced the judgment are different kinds of statement. Why capsules keep nine named graphs with distinct mutability contracts instead of one big graph.
An HR caseworker’s triage instincts, a mediator’s sequencing, a speechwriter’s forbidden words — the most valuable knowledge in any institution was never written down. How structured elicitation turns it into typed, attributable capsule content, and why the 1980s expert-systems failure does not repeat.
