Roadmap

What ships next — with honest status labels.

The earlier "LEXUN Labs" prototype has been retired. It made the kind of claims this product exists to fight — a "search engine for tomorrow" cannot be re-run, sourced or scored. Its worthwhile ideas now live here as staged roadmap items. Nothing on this page is a promise with a date; everything carries its real status.

Live — released and test-gated

  • Three released models — business runway, career change, major purchase — seeded, banded, challenge-checked. LIVE
  • Decision Reality layer — monitored assumptions, materiality checks, forecast versioning, trust receipts, .lexun export. LIVE
  • Verifiable sharing — verdict cards, re-runnable receipt links, second opinions. LIVE
  • Off-thread engine with streamed evidence — the simulation runs in a Web Worker and the homepage draws its five thousand paths as they arrive, held to the model path-for-path by the build. LIVE
  • Stated model weaknesses — each model's blind spots documented from its own recurrence on its own page, linked from every result. LIVE
  • The Zero-Fault Release Gate — thirty-eight gates behind one command — every one of them shipped inside the release bundle, so the number is what an owner can run, not what a table lists — including mutation tests that inject deliberate contradictions and fail the build if the gate misses any; a critical failure blocks the release instead of warning. Its coverage is its gate list, no more: a defect no gate asserts on can still ship — several have, found by outside readers — and each found one becomes a new gate. “Zero-fault” names the policy for what the gates test, not a claim that nothing outside them can be wrong. LIVE
  • The truth registry & contradiction engine — one machine-readable source for every public product fact, and a build gate that fails the release when any page disagrees with it. LIVE
  • Verified company identity — operator, company number and registered office published in full on every page. LIVE
  • Survival through time, and the tail — runway results carry the month-by-month survival curve and the end-cash percentiles, counted from the same seeded paths as the probability, with every result stating what it covers and what it does not. LIVE
  • What would change my mind — every result now names the smallest single change in each driver that moves the published band, in both directions, computed by re-running the same model rather than described in prose. LIVE
  • Three audiences, namedindividuals, organisations and education each get a page that says what the engine does for them, what is free and what is not, with limits stated rather than hidden. LIVE
  • The paid door, gated — the assistant endpoint answers only this site’s own pages, caps each visitor’s pace, and /api states plainly that hosted keys ship with paid plans; there is no free public endpoint. LIVE
  • The live workspace engine — the framing form previews its band as you type (unfrozen, unbilled, gate-aware), and every runway result streams its five thousand futures onto the page from the same seed. LIVE
  • The premium command surface — one treatment for every place a person types a decision, example chips that compute and wear their own probability bands, and scrubbable sensitivity: drag a driver ±20% and the frozen model re-runs live, its what-if band labelled modelled. LIVE
  • The Decision OS layer — Decision Inbox, pre-mortems derived from the engine’s own output, hash-chained decision timelines, Outcome Day, and an Evidence Wallet inside the encrypted store, all driven end-to-end by a sixteen-step browser gate. LIVE
  • The capability firewall, everywhere — unsupported questions are refused out loud on the homepage, workspace, search and shared receipts; broad “Should I?” questions arrive narrowed to what the model calculates, with what it cannot determine said next to it. LIVE
  • Decision readiness and the Assumption Lab — the form states, before the run, whether the evidence gate will open and why; every result offers its biggest driver for a baseline-versus-adjusted comparison, two real runs on the same model version. LIVE
  • The living entrance — the homepage photograph breathes, its real city lights shimmer and switch, and the words land on the planet as you scroll. Reduced motion gets the same picture, still. LIVE

Building next

  • Public forecast register — dated, frozen predictions with named resolution sources, misses and withdrawals published permanently. The register opened on 14 August 2026: ten issued, four withdrawn in the open with their reasons readable, and the first outcomes now scored — every count on every page reads live from the ledger. Issuing, withdrawal and resolution each run through a gated tool that refuses backfilling, hindsight leaks, unreachable due dates, second outcomes and evidence from the wrong source. LIVE
  • First resolved outcomes — three forecasts resolved against their frozen sources on 18–19 August 2026: unemployment 4.9% in-band (TRUE, Brier 0.0100), July CPI 2.9% in-band (TRUE, Brier 0.0121), and the deliberately-uncertain CPI-fall call (FALSE, Brier 0.2500 — the first honest miss, scored exactly as written). The July insolvency forecast stays open until its gov.uk source can be verified — a register never resolves on a secondary source. No accuracy figure appears until a scoreboard holds ten. LIVE
  • Calibration League — fast-resolving weekly public questions with personal Brier scores, architecturally separate from the release-gated models. BUILDING
  • ICO registration — the fee assessment is done (Tier 1), the answer sheet is written, and publishing the reference is one command once the fee is paid. The Privacy Policy says “pending” because it is, and the build fails if either state is misdescribed. BLOCKED — EXTERNAL ACTION
  • Question registry and versioning — one canonical, versioned source for every question the site asks, so saved decisions keep the wording they were made under. PLANNED
  • Compare two commitments, side by side — the same model, same horizon, compatible seeds, one table; the financially safer option never sold as the universally better one. PLANNED
  • Pro plan — £9 a month or £79 a year: every decision kept, exports, PDF reports and the calibration view, with Stripe Checkout, a 14-day trial without a card and a plan confirmed against Stripe rather than trusted from the browser. Encrypted sync across devices and emailed reminders remain PLANNED. Plans. RELEASED

Concepts — from the retired Labs, kept only if they can be made honest

  • Household "twin" planning — multi-decision budgets across a family. Needs the dependency engine to mature. CONCEPT
  • Sector base-rate packs — reference classes per industry, each with a named source. Blocked on sourced data, by design. CONCEPT
  • Live data connectors — bank/accounting feeds updating monitored assumptions, opt-in only. CONCEPT

Retired — and why

"Future Simulator", city futures, lifespan and health modules, the live world feed, "command centre for whole nations": retired because none could meet the bar the rest of the product is held to — a displayed number must be reproducible or sourced. Retiring your own features for honesty reasons is the cheapest credibility we will ever buy. The claims registry records what was removed.
