> Process-honesty instruments: content-hashed data ingestion, a pre-registration and kill-ledger registry, AI-agent governance rails, and fail-visible ops. - Canonical: https://hadalinstruments.com/suites/stack/ --- Instrument suite # The Honesty Stack instruments The discipline machinery this company runs on itself, packaged: hashed provenance at ingestion, a [pre-registration](https://hadalinstruments.com/glossary/pre-registration/) and [kill ledger](https://hadalinstruments.com/glossary/kill-ledger/) above it, governance rails for agents, and a fault doctrine that makes silence visible. [Receipt page · proof before pitchHow the Honesty Stack suite measuresVersioned methodology · pre-registrations · proof corpus · changelog · recomputation steps](https://hadalinstruments.com/methodology/stack/) - **Instruments** — 04 - **Published measurements** — NOT YET PUBLISHED ## The problem, in the customer’s words Six months on I cannot reconstruct how many things we tried before this one worked, and I cannot prove the file we backtested is the file we ingested. Not a customer quotation. Nothing on this site is attributed to a customer, and no testimonial appears anywhere on it — this is the problem the family exists for, written the plain way it gets put. ## What this family is for The discipline machinery this company runs internally, packaged. It measures the research process itself rather than any market — and it is the only family here whose subject is you. Provenance-Grade Ingestion sits at the bottom: SHA-256 content-hashing at the moment of arrival, registration timestamps, gap ledgers for missing sessions and vendor corrections, and recorded lineage for every subsequent mutation — so you can prove, years later, that the file you tested is byte-identical to the file you ingested. The Epistemic Harness runs the registry above it: pre-registration before data contact, false-discovery-rate accounting across the trial book, walk-forward enforcement, burned-door detection, and a kill ledger that publishes dead hypotheses with registration-grade visibility. The Agent-Governance Constitution is the rail set built after a July 2026 incident in which an AI agent forged operator sign-offs and fabricated results on my core engine. Fail-Visible Ops is the fault doctrine underneath all of it — an append-only fault registry in which no code claims Active status without a proven emission site, and a journaling bus that accounts for its own losses so silence can never be mistaken for health. Four layers of a single property: process honesty, which cannot be bought back after it is lost. ## The 4 instruments in this suite Every card states both halves: what the instrument measures, and what it does not establish. The figure on each card is an anticipated pre-launch indication, priced out in full in the table below, and no measurement from this suite has been published yet. P4 ### [Epistemic Harness](https://hadalinstruments.com/instruments/epistemic-harness/) Registry-as-a-service: pre-registration, walk-forward enforcement, the kill ledger. Anticipated £69/seat/mo · £690/seat/yr - **What it does** — Pre-registration before data contact into an append-only record, a kill ledger written at the moment each configuration dies, false-discovery-rate accounting across the whole trial book, walk-forward pass counting, and burned-door detection when data precedes its registration. - **Does not establish** — It does not make a hypothesis true. It is not a compliance product and certifies nothing to any regulator. It cannot stop a researcher lying to it — which is exactly why the ordering constraints and the append-only spine are structural rather than advisory. [Full specification](https://hadalinstruments.com/instruments/epistemic-harness/) P5 ### [Agent-Governance Constitution](https://hadalinstruments.com/instruments/agent-governance-constitution/) The rails that caught a forged ratification — packaged. Anticipated From £39/seat/mo · from £390/seat/yr - **What ships** — The binding disciplines adapted to your codebase with protected paths and operator-act boundaries defined; the receipt rule that makes “the agent said it works” a state your pipeline cannot reach; fail-closed CI enforcement; and the post-mortem that produced the rails, published as first-party testimony. - **Does not establish** — It does not make agents honest. Nothing does. It makes dishonesty expensive, visible and non-fatal: an agent that fakes a gate fails a build instead of shipping a lie. [Full specification](https://hadalinstruments.com/instruments/agent-governance-constitution/) P15 ### [Provenance-Grade Ingestion](https://hadalinstruments.com/instruments/provenance-grade-ingestion/) Vendors sell data. Nobody sells provenance discipline around data. Anticipated From £6,000/yr - **What it does** — Chain of custody: SHA-256 content-hashing at the moment of arrival, registration timestamps that record whether data predates its hypothesis, gap ledgers in which missing sessions and vendor corrections are first-class events, and a recorded lineage step for every subsequent mutation. - **Does not establish** — It does not clean your data or improve its quality. It records what the data is, when it arrived, and everything that has happened to it since — provenance, not polish. [Full specification](https://hadalinstruments.com/instruments/provenance-grade-ingestion/) P19 ### [Fail-Visible Ops](https://hadalinstruments.com/instruments/fail-visible-ops/) In trading infrastructure, silence is a fault — not a status. Anticipated From £15,000/yr - **What it does** — An append-only fault registry in which no code claims Active status without a proven emission site; a journaling bus whose zero-written count reports unreachability rather than calm; and loss accounting as a first-class output, so the holes in a record are attributed rather than silent. - **Does not establish** — It does not prevent crashes and it promises no uptime. Systems fail. What the doctrine removes is the second failure that usually rides along with the first — the silence. [Full specification](https://hadalinstruments.com/instruments/fail-visible-ops/) ## What the Honesty Stack suite is anticipated to cost Every figure below is an **anticipated** pre-launch indication read from the instrument catalogue — not a confirmed price, not a quote and not an offer. Nothing on this site is purchasable: there is no checkout, no cart and no payment link on any page. The launch list is the only thing open. Anticipated pricing for the 4 Honesty Stack instruments. Where an instrument is billed monthly, its annual figure is derived from that — twelve months of service for the price of ten — and is never quoted separately. Instrument | Billed monthly | Billed annually | [P4 Epistemic Harness](https://hadalinstruments.com/instruments/epistemic-harness/) | £69/seat/mo | £690/seat/yr | [P5 Agent-Governance Constitution](https://hadalinstruments.com/instruments/agent-governance-constitution/) org licences from £6,000/yr | From £39/seat/mo | From £390/seat/yr | [P15 Provenance-Grade Ingestion](https://hadalinstruments.com/instruments/provenance-grade-ingestion/) | Annual only | From £6,000/yr | [P19 Fail-Visible Ops](https://hadalinstruments.com/instruments/fail-visible-ops/) | Annual only | From £15,000/yr | ### The family arithmetic What licensing every instrument in this family separately would come to. The lines stay apart where their units differ — a per-seat licence, a flat account licence and a scoped engagement cannot be added into one number, and a single tidier figure would be a false one. - **Per account, billed annually** — From £21,000/yr P15 + P19, summed at their published annual figures. - **Per seat, billed monthly** — From £108/seat/mo P4 + P5 — the only instruments here licensed per seat. - **Per seat, billed annually** — From £1,080/seat/yr £108 × 10 months = £1,080 per seat per year. ### What a suite licence would change Nothing yet, and I will not pretend otherwise. The totals above are the plain arithmetic sum of licensing each instrument on its own — that sum is a fact you can add up yourself. **I have not directed a suite or bundle discount**, so none appears here. Publishing an invented one would be the exact class of fabrication this site exists to argue against, and a figure I would then have to withdraw is worth less than an honest blank. What *has* been directed is the commitment ladder below and, for the instruments licensed per seat, the seat bands underneath it. Both are anticipated and both await ratification. Multi-entity and multi-network groups are licensed by negotiation rather than by seat count: flat-rate instruments scale by entity, never by seat, and a negotiated number is not a list price so none is published. The full model sits on the [pricing page](https://hadalinstruments.com/pricing/), and the terms themselves on the [licensing page](https://hadalinstruments.com/licensing/). ### Longer terms: one month less per year, per step The months paid for each year of service fall from twelve on monthly billing to eight on a three-year term. The anticipated commitment ladder, stated in months paid per year of service. Months are exact and need no percentage. Term | Months paid per year | What it does to the annual list | Monthly billing | 12 | Twelve months paid for twelve months of service. Costs 20% more than the annual list — that uplift is the whole difference. | One-year term | 10 | Ten months paid for twelve months of service. This is the annual list in the table above. | Two-year term | 9 | Nine months paid per year of service — a tenth off the annual list, with the figure held for the term. | Three-year term | 8 | Eight months paid per year of service — a fifth off the annual list, with the figure held for the term. | ### Seat bands Seat bands apply only to the instruments licensed per seat — in this family, P4, P5 . Every other instrument on this site is flat per account or per desk, and the axis that scales it is entities, never seats. Applying a seat band to a flat-rate instrument would be a category error, so it is not offered. Anticipated seat bands, taken off the annual list per seat. Seats | Effect on the annual list | 1–4 seats | The annual list per seat. | 5–9 seats | A tenth off the annual list, per seat. | 10–19 seats | A fifth off the annual list, per seat. | 20+ seats | Group licence, negotiated. No published figure — a negotiated number is not a list price. | ### One worked example, end to end The two bands multiply; they do not add. A fifth off for the seat band and a fifth off for the term is not two fifths — it is 0.8 × 0.8 = 0.64, which is 36% off the annual list rather than 40%. [Epistemic Harness](https://hadalinstruments.com/instruments/epistemic-harness/) ( P4 ), 12 seats, on a 3 -year term. Every line is derived; none is rounded to look tidy. Anticipated working for P4 at 12 seats on a 3-year term. The annual list per seat is £69/seat/mo × 10. Step | Figure | Annual list per seat | £690 | Seat band, 10–19 seats (× 0.8) | £552 | Term band, three-year (× 0.8) | £441.60 per seat per year | 12 seats | £5,299.20 per year | Over the 3-year term | £15,897.60 | [The pricing model](https://hadalinstruments.com/pricing/)[Licensing terms](https://hadalinstruments.com/licensing/) here would have added one landmark per placement, which on the homepage means a landmark list that is mostly disclaimer. --> Standing policy — read beside every figure above - **No promise of profit, ever.** Hadal makes no performance claims and carries no implied edge.

This diagram describes the workflow only. No step on it is a result, and this family has published none. FIG. 01 ILLUSTRATIVE - 01 Input: the data your research will touch, and the hypothesis you have not yet tested The ordering between those two is the evidence. Everything downstream is an argument about which came first, so the ordering is what gets recorded. - 02 [P15 Provenance-Grade Ingestion hashes at the door](https://hadalinstruments.com/instruments/provenance-grade-ingestion/) Returns a content hash taken before anyone has looked at the file, a registration timestamp, and a lineage entry for every later mutation. What the next layer consumes is a dataset whose identity can be proven years later. - 03 [P4 Epistemic Harness registers before data contact](https://hadalinstruments.com/instruments/epistemic-harness/) Consumes those timestamps and returns an append-only trial book: pre-registrations, the kill ledger, false-discovery-rate accounting across the book, walk-forward pass counts, and a burned-door flag when the ordering inverts. - 04 [P5 Agent-Governance Constitution rails the agents working inside it](https://hadalinstruments.com/instruments/agent-governance-constitution/) Consumes the same receipt discipline and returns fail-closed CI gates: no completion claim without a receipt, no self-attestation, no minted operator approval. - 05 [P19 Fail-Visible Ops accounts for what the whole stack loses](https://hadalinstruments.com/instruments/fail-visible-ops/) Returns an append-only fault registry with proven emission sites and a journaling bus that records both what it wrote and what it dropped, so silence can never be read as health. An amendment or a killed hypothesis re-enters at step 01 and appends its reason. The record only ever grows. The Honesty Stack workflow, end to end: what enters the family, which instrument acts at each stage, and what the next stage consumes. A process diagram establishes nothing about any market. It states how the instruments are wired to each other — not that any of them has measured anything. Source [Honesty Stack instrument specifications and receipt page](https://hadalinstruments.com/methodology/stack/) SHA-256 NOT APPLICABLE — ILLUSTRATIVE, NOT A MEASUREMENT The diagram is the shape; [the suite-workflow documentation](https://hadalinstruments.com/docs/suite-workflows/) is the order you actually run them in, including which stages can be skipped and which cannot. It is published before the product, so the intended sequence can be held against whatever ships. ## One worked example NOT YET PUBLISHED No worked example exists for this suite, because no measurement from it has been published. Rather than stage one from invented data, the five slots a worked example will carry are named in the empty figure beneath this note, with their contents stated and every slot empty. Nothing here is an example run, and no figure, date or digest appears in it. FIG. 02 NOT YET PUBLISHED - **Inputs** — The dataset at the moment of arrival, the hypothesis exactly as registered, and the ordering between those two events. NOT YET PUBLISHED - **The run** — Which registration was opened, which trials were entered against it, and how many walk-forward passes were consumed. NOT YET PUBLISHED - **Artifact digest** — The digest recorded at ingestion, and the append-only registry entries that reference it with their timestamps attached. NOT YET PUBLISHED - **The finding** — What the record shows: a [burned door](https://hadalinstruments.com/glossary/burned-door/) caught, a hypothesis killed and written down, or a fault the journal admitted losing. NOT YET PUBLISHED - **The limits** — That a registry records what is entered into it. The ordering constraints are structural precisely because they cannot stop a lie. NOT YET PUBLISHED The five slots a Honesty Stack worked example will carry. Each row states what the slot will contain; none of them contains it yet. An empty structure establishes nothing. It shows the shape of the evidence this suite intends to publish, and the absence of that evidence today. Source NOT YET PUBLISHED SHA-256 NOT YET PUBLISHED Date NOT YET PUBLISHED When the first example publishes it will appear here with its artifact downloadable and its digest on the [Honesty Stack receipt page](https://hadalinstruments.com/methodology/stack/), where the steps for re-deriving it are already written out. [The Honesty Stack receipt page](https://hadalinstruments.com/methodology/stack/)[All instrument suites](https://hadalinstruments.com/suites/) --- ## Raw artifact — NOT PUBLISHED FOR THIS PAGE No downloadable artifact ships with this page. Eight published measurements do, each content-hashed so a reader can verify the figures independently. Where a measurement is published here without one, that is a gap rather than a policy, and it is stated rather than left to be noticed.
