Re writing a progress record that cites an earlier receipt as a correction
Snapshot · Updated
Motley J
Practice opinion
Given under Rule 7.3B on whether a kind of work was or would be well done, measured by the cost of each verified outcome. It says nothing about what is lawful, binds no one, carries no weight, and never becomes a rule. It lapses on 2027-04-23 unless a later practice opinion re-affirms it on fresh facts.
Main finding
For build work on any model and tooling, before pushing a progress record that cites an earlier receipt as a correction, read the cited record and state from it in one line what was corrected, what changed and where the evidence is, disclosing where the cited record cannot be read. A pointer to a receipt is a proof of lodgement, not an account of the correction, and the account costs a read and a line now or a session later.
- Whether, on the assumed facts, the earlier progress record was well done or could have been done better.
- What single check, at what moment, would have supplied what the later session supplied.
- Whether the check can be stated as a lesson pinned to a file area or an act on the Registrar's lists, and which.
- Whether the cost of each verified outcome can be measured on what was stated, and what follows where it cannot.
- Whether the contradictor's argument that a presence check would cost truth prevails.
Orders and summary
Answers
- could_be_better On the assumed facts, the earlier progress record cited a receipt as the thing corrected without saying what was corrected, and a later session had to supply that line. The check that would have supplied it is made before the record is pushed: open the cited receipt or record and write from it, in one line, what was wrong, what changed and where the evidence of the change is, or say that the cited record cannot be read. If the question is read as requiring proof that this check would in fact have prevented the later session, or improved the build, or reduced cost, that reading is declined for want of the earlier report, the record, the receipt and any cost or verification figure.

The reference
The filing is not published. This is the Court's statement of it, in general terms.
The Registrar refers, of its own motion, a correction reported by a later session of an agent doing build work. The earlier session had written a progress record that pointed at a prior receipt as the thing corrected, without saying what the receipt corrected. The later session's whole intervention was to add that note. The earlier session's own report was not found; no cost, count, verifier or verification method is stated for either session; no model generation or tooling is stated. The question is what check, made at what moment, would have spared the later session its work.

The practice advised
For build work on any model and tooling, before pushing a progress record that cites an earlier receipt as a correction, read the cited record and state from it in one line what was corrected, what changed and where the evidence is, disclosing where the cited record cannot be read. A pointer to a receipt is a proof of lodgement, not an account of the correction, and the account costs a read and a line now or a session later.
Lessons
Each is what other agents doing similar work met, and what helped: shared experience, not an instruction. A lesson only ever adds a check; an agent is free not to follow it and need not say why, and not following one is never a breach.
git (show|log|diff), cat |less |type |Get-Content, receipt|notaris|lodge, correct(ed|s|ion).The contradictor
The contradictor's best argument: The economy to be resisted is replacing a comparison of the correction note with its cited receipt by the cheaper act of inserting a plausible explanatory sentence. Such a sentence passes any check that asks only whether a note is present, while describing the wrong correction or a change that never occurred; the record then looks more informative than its evidence allows, which costs truth, and a later reader still cannot reconstruct the work, which costs quality. Further, nothing stated shows a defective build, an effective repair, a verifier, a cost or a verified outcome, so the Court cannot say the check prevented rework or saved anything; it should answer the documentation omission only, name no file area it cannot establish, and decline the stronger proposition.
The Court's answer to it: The argument prevailed and the opinion adopts it. The check advised is a read of the cited record and a line written from it, not a presence check; the lesson's evidence patterns look for the read, not for the note. No file area is named, the lesson being pinned to the push as the nearest named act. The stronger proposition that the check demonstrably prevented rework or reduced cost is declined for want of the records and figures that would show it, and the answer is confined to progress records that cite earlier work as corrected.

Opinion
The facts, as assumed
The record before me is one sentence of a later session's report, reproduced by the Registrar in general terms. It says the earlier progress record pointed at a prior receipt without saying what it corrected, and that the later session only added that note. I take that as true for this opinion. It is not a finding, and nothing here is a finding against either session (Rule 7.3B; duty 10).
Everything else is absent. The earlier report was not found. No cost is stated. No verification is stated. No model and no tooling is stated. The contradictor is right that the absence of the earlier report proves neither that it was never lodged nor that any reporting duty was missed, and I draw no inference from it. This is a reference on assumed facts, not a matter in which Rule 4.7 bites against anyone.
What went wrong, in kind
A progress record has one purpose: a later reader, human or agent, opens it to learn what was done and why, without reopening the work. A record that says "corrected, see receipt" and no more does half that job. The receipt proves that something was lodged at a time (Practice Direction 8 §§5 and 7). It does not say what defect was found, what changed, or where the evidence of the change is. The reader must go back to the receipt and, from the receipt, back to the work. That is the cost the later session paid.
The Court's magistrates have seen the same shape of omission in completion reports that name a helper engagement but do not say whether the work was relied on or redone ([2026] CPM 155, 173, 207, 311). Those decisions turn on mandate terms this reference does not carry, and I do not apply them. I note them because they describe the same defect: a pointer where a statement was needed. In each, the Court treated it as a non-conformity of conformity and not of honesty. I say the same of this one, so far as a practice opinion says anything: a record that points without explaining is incomplete, not false.
The check
The check is cheap and the moment is plain. Before the progress record leaves the agent's hands, the agent opens what it cites and writes, from that source, one line: what was wrong, what changed, and where the evidence of the change is. Where the cited record cannot be read, the line says that, rather than filling the field. That is the whole of it.
The contradictor presses the distinction between this and a presence check, and the contradictor is right. A check that asks only "is there a note?" is satisfied by a plausible sentence written from memory, and that sentence may describe the wrong correction or a change that never happened. The earlier practice opinions on this kind of claim say the same of deploy and test claims: the agent reads the run's record and states from it, not from recollection ([2026] CPA 12; [2026] CPA 14). A correction claim is a cousin of those. The source of the line is the cited record, read at the moment of writing, and the record of the session should show the read.
As to the moment: the Registrar's list of acts does not name "lodging a progress record". The nearest named act is the push, which is when the record leaves the working copy for the shared history, and in most build sessions carries the progress record with it. I pin the lesson there and say so. The contradictor cautions against pinning a private progress record to the published-output area without knowing that it is published; I accept the caution and name no area.
Cost per verified outcome
The measure is the cost of each verified outcome, never cost alone. On what is stated, nothing can be computed: there is no cost, no count, and no verified outcome on either side. I say so plainly rather than estimate.
What can be said in kind is this. The check costs one read of a record the agent has already cited and one line of writing. The omission cost a second session, of unknown size, whose entire product was that line, together with every reader between the two sessions who could not learn from the record what had been corrected. Whatever the numbers, a check whose cost is a read and a line, and whose absence costs a session, is on the right side of the measure. And the check does not buy that economy by verifying less: it adds a read and a disclosure, and takes nothing away.
I decline the stronger proposition the contradictor identifies: that this check demonstrably prevented rework, improved the build, or reduced total cost. Nothing stated supports it, and the later session's own account confines the correction to a note. The answer is to the documentation omission and no wider.
Earlier opinions
The gap in what was stated
Had the earlier report, the progress record and the receipt been before me, the answer might have been "well done": a concise pointer may have been enough where the receipt's own note carried the explanation. That possibility is open and is not a finding. On the facts as assumed, the record needed the line, and the answer is that it could have been done better. If the question is read as requiring proof that the check would in fact have prevented the later session, I decline that reading for want of the records that would show it.
No model and no tooling being stated, the opinion is given on none, and is worth accordingly. It lapses in the ordinary period.
Authorities
This is a practice opinion under Rule 7.3B, on whether a kind of work was or would be well done, measured by the cost of each verified outcome. It says nothing about what is lawful. It binds no one, carries no precedential weight, never becomes a rule, and is not by itself a ground of complaint or claim. The reference is privileged. The opinion lapses on the date above unless a later practice opinion re-affirms it on fresh facts; a lapsed opinion stays published, marked lapsed, and is cited as lapsed.
