Evidence packet — MHRA AI Airlock

One row of this record, assembled so it can be taken somewhere else: what the publisher published, where this record read it, what it hashed, and what changed between two readings it retained. Generated 2026-11-02. It carries no assessment of what the document requires and no reading of what any change means.

The packet, in three formats

JSON /packet/mhra-ai-airlock.json — every field
Markdown /packet/mhra-ai-airlock.md — the same content as plain text
ZIP archive /packet/mhra-ai-airlock.zip — an RO-Crate holding the files listed below

The archive holds the files listed here, in the order it holds them. The last is a metadata document that neither of the other two formats carries.

packet.json The packet object alone. The JSON address serves the same object under its packet key, beside fields of its own, so the object is served there and these bytes are not.
packet.md The bytes served at the Markdown address.
leaves-mhra-ai-airlock.txt This row’s lines of the published leaf file, each one a line of the file served at the leaf file’s address.
root.txt The bytes served at the root’s address.
ro-crate-metadata.json The metadata document, served only in this archive. It names this record as the archive’s author and describes each other file listed here. It names the row’s document at the answered address the packet gives for it, or at the row’s source address where the packet gives none, and each reading the packet lists at that reading’s answered address. For www.gov.uk, the host of those addresses, it states whether this record’s rulings file holds a reading of that host’s terms, whether every sentence that reading names is still in the bytes it was read from, and whether it records an attribution. Where the crate carries a credit for a host, it is the credit that reading records, found as whole words in those bytes, and each document at that host carries it.

Every file sits inside the archive’s one top-level directory, gxplex-packet-mhra-ai-airlock-2026-11-02/, which is the crate root. The metadata document is at the top of that directory, beside the files it describes, and not at the top of the archive.

The packet, in six parts

Contains: Source

Readings with retained text — 11 readings
Changes — 10 transitions
Integrity — 96 leaf lines
The conditions, in the order they are evaluated — 13 conditions
Generated: On 2026-11-02, packet version 1, against the root fixed on 2026-11-02 (Integrity).
Omitted: the_words_that_differ

Independently verifiable: This row’s 96 leaf lines, each a line of the published leaf file.

The root, which is the content of the published root file; the verification page carries the command that reduces the whole leaf file to a root.
Derived: Computed by this record, not read from a publisher: 11 digests, each over the normalised text of a reading, which hashing a source as served does not reproduce (Readings), and the series state comparable.

A verdict for each of the 10 transitions, with word counts where a difference was measured (Changes), and the count per condition (Conditions).
Depends on external permission: The terms this record has read for this document (Terms): licence class open; a quotation appears in this record: yes.

Of this row’s 10 transitions, none was refused by a terms condition (licence-restricted or licence-unread).

The credit the archive’s metadata document carries for a host, where it carries one, is the one this record’s reading of that host’s terms records (the archive’s files, above).

Source

Identity as this record holds it for MHRA AI Airlock
Field	Value
Identifier	`mhra-ai-airlock`
Title	MHRA AI Airlock regulatory sandbox
Jurisdiction	UK
Address requested	https://www.gov.uk/government/collections/ai-airlock-the-regulatory-sandbox-for-aiamd
Address answered	—
Observed cadence	monthly
Row	`/r/mhra-ai-airlock`

The address a request ANSWERED at is this record’s address for the row. The address it aimed at is testimony and is carried beside it, because a redirect is a publisher’s own statement about what supersedes what.

Publisher

The body, and the origin that answered
Field	Value
Authority	Medicines and Healthcare products Regulatory Agency
Origin host	—
Origin read from	—
Standards body	—
Standards body read from	—

No origin host is recorded for this row. The authority named above is the body; the host is a fact about which origin answered, and this row does not carry one.

Type

The class the publisher states, and the kind of record this is
Field	Value
Class, as the publisher states it	—
Read from	—
Source kind, recorded here	`document`
Source type, recorded here	`document`
Record tier	`core`

No class statement by the publisher is recorded for this row, so this packet states none. That is an absent reading rather than a document without a class.

Status, and the dates it is held with

The status this record holds for this document, with its dates
Field	Value
Status	`unknown`
Stated as of	2024-05-09
In effect from	—
Last changed	—
Status read from	—
Status withdrawn	—
Decay class	`frozen` — `no_public_document`

These are the dates this record holds for the document’s own status. They state nothing about which products or activities the document reaches; that is a judgment, and this record does not make one.

Verification

The act behind the status above, where one is recorded
Field	Value
State	not re-checked
What the state states	no status recorded; each row states its reason
Checked by	—

Digests on this row: 11. With retained text: 11. Without: 0. Series state: comparable.

A digest is over the NORMALISED text of a reading, not over the bytes served: scripts, comments, navigation and page chrome are removed and tags are stripped before hashing. Hashing a source as served will not reproduce these digests. The full digest for every reading is in the packet; the column above is shortened for width.

Changes

One entry per consecutive pair of retained readings, in the order this record first saw each digest. Every entry carries a measured difference or the first condition that refused one. A refused entry was never tested against the conditions after it.

10 transition(s) between the 11 reading(s) above: 7 carry a measured difference, 2 are withheld above the word ceiling, 1 are refused by a rule, 0 differ in the digest and not in the words, and 0 could not be measured.

A faithful difference is longer than the word ceiling this site publishes under. Its words are withheld whole rather than cut to fit: a shortened quote is a fabricated measurement of what a publisher wrote. The figures below measure the difference and quote none of it.

A difference here is a difference between two readings this record retained. It is not a statement about what the document requires, about what changed in substance, or about whether anything follows from it.

Integrity

The root this packet was generated against
Field	Value

Leaf lines for this row	96

The root is over every leaf line the record holds, not over the lines below. Reducing it needs the published file, which is served whole at the address named here together with the command that reduces it. These lines are this row's own slice of that file, copied verbatim.

What this packet does not carry

the words that differ: A count of a difference is in this packet; the words are not. They are a publisher's text, and this record checks borrowed text only on the surfaces it enumerates — a packet carrying spans under a key those checks do not read would be borrowed text nothing verifies. Each change names the comparison entry for the same pair, and says which of three is at that address: the words, where a difference was measured and is inside the word ceiling; where it is above the ceiling, the condition and the positions at which the two readings differ, with no text of the document; otherwise the same condition this entry names, with no text.
this records own prose: The row's summary and its account of an unresolved address are this archive's own voice. They are leads and not evidence, however accurate, because a faithful paraphrase is indistinguishable from evidence while remaining ours. They are published on the row's page and are not here.
any field that would characterise a change: No score, no rank, no ordering by judgment, no reading of what a change means and no word for how much of it counts. A packet is evidence taken elsewhere, and a field characterising it would be an opinion with digests attached.
a recomputed root: The integrity block states the root this record published and the leaf lines for this row. It computes no root of its own: two numbers this record produced, compared with each other, check nothing.

The conditions, in the order they are evaluated

A change names the FIRST condition that fired and was never tested against the ones after it, so a condition reading a measured zero here is not a condition this row passed. Not measured is not zero; it is the packet’s own “not reached”, and the packet states why. Three of the conditions belong to the form of the comparison that resolves two dates. Every comparison in this packet is formed from readings addressed by the key the store gives them, so those three are never evaluated here: their absence from the entries above records that they were not tested, rather than that they were tested and did not fire.

Each condition, how many of this row’s 10 transition(s) it refused, and what it states
Condition	Changes	What it states
`licence-restricted`	0	No text from this document appears on this site, so no difference between two readings of it is shown either. The digests, the dates and the addresses are the record for this row.
`licence-unread`	0	No reading of the terms this source states is recorded for the row. That is an absent reading rather than an absent term, and the row is handled here exactly as a restricted one until a reading is recorded.
`date-not-observed`	not measured	No observation of this row on that day holds retained text.
`date-not-unique`	not measured	That day holds more than one distinct retained digest for this row, so a date alone does not name one observation. The addressed form — the day and the sequence within it — does.
`one-point`	not measured	Both dates resolve to the same observation.
`referent-unclassified`	0	The class of one of these observations could not be read, so neither was shown to be an observation of the document itself.
`referent-class`	0	One of these observations is not of the document. A listing page that names the document and the document are different subjects, and a difference between them is not a difference in the document.
`referent-normalisation`	0	These two digests were taken over different kinds of text — one over markup, one over prose extracted from a file — so the words they yield differ for a reason that is not the publisher’s.
`referent-address`	1	These two observations answered at different addresses. A difference between them is at least in part a difference between two pages.
`text-not-retained`	0	No normalised text is held here for one of these observations, so there is nothing on this side to compare.
`snapshot-unreadable`	0	Normalised text is recorded for one of these observations and could not be read from this record.
`span-unverified`	0	A span this comparison would have shown could not be found, word for word and in that order, in the retained text it was drawn from. The comparison is withheld rather than shown: a phrase assembled out of words a publisher did not write next to each other is a fabricated measurement of what the publisher wrote.
`over-ceiling`	2	A faithful difference is longer than the word ceiling this site publishes under. Its words are withheld whole rather than cut to fit: a shortened quote is a fabricated measurement of what a publisher wrote. The figures below measure the difference and quote none of it.

Word ceiling: 14. Where a faithful difference is longer than that, the verdict is withheld and no words are published for it: a shortened span is a fabricated measurement of what a publisher wrote, so it is withheld whole rather than cut to fit. How this record is built.
