The Mislabeled File: Mexico City’s Pothole Law, Football’s Grammar of Sanction, and the Memory Data Needs

The label pinned to the top of the file was a single word — football.

Inside, the headline asked whether filling a pothole on a Mexico City street yourself can cost you a fine, and what the law says. The cited source was the Civic Culture Law, Articles 27 and 28. Inside there was no club, no player, no coach, no league, no scoreline. The label sat there anyway — football.

Documents like this do not land on my desk every day. The press box doubted me, so I rewatched the second half twice — that sentence is the short form of my working habit. The rewatch taught me that the real event lives beneath the scoreline. The same rule applies beneath a label. When a document falls into the wrong folder, the problem is not its content; the problem is its identity card.

And a wrong identity card does not stop at one document. It travels into dashboards, into training data, into the report you will pick up with your morning tea.

What was actually inside the file

The event is simple; the explanation is not. Potholes on Mexico City roads, neighbours organising to fill them themselves, and one question: can a good act be fined?

The Civic Culture Law does not literally list filling a pothole as an offence. Liability arises from adjacent conduct — obstructing a roadway or public space without authorization, or altering the character of that space. Article 27 (fraction IV) and Article 28 (fraction II) together build a structure: a general rule, then specific conduct, then a conditional infraction, and finally an escape route. Article 28 states the condition plainly: where there is justified cause, no liability attaches. The provision still stands in the current text cited by the Mexico City Congress.

The matter should have ended there. But the analysis pipeline that delivered the document exposed the problem inside its own house: the Entities Involved field sits empty, holding an instruction rather than a club or a player's name. The pipeline confesses with its own hand that no football entity exists here. A human editor touching the manual would have filed the paper straight into the civic-law folder.

One grammar of sanction, one nearly identical vocabulary

Here lies the real thing, and it is not a matter of law but of grammar.

The real work of any rule system happens inside the condition, not in the announcement. Declaring a general rule is easy; the hard work is drawing the boundary between specific conduct and its exception. What the Civic Culture Law does, UEFA's Financial Fair Play and the Premier League's Profit and Sustainability Rules do as well — general rule, specific calculation, conditional breach, and a set of exceptional definitions.

The numbers differ; the grammar is identical. Manchester City's 115 charges brought in February 2026, Everton's ten-point deduction later reduced to six, Nottingham Forest's four-point deduction — in none of those cases did the panel ask whether the people involved meant well. The question was narrower: does the spending fall inside the clause?

Inside a rule system, protection comes from the language of the clause, not from intent. When a Mexico City neighbour fills a pothole with his own money, what he does is good; the law looks at whether the work is authorized. When a football club claims it lives within its own revenue, the club may be telling the truth; the board looks at whether the accounting falls inside the definition.

Look at VAR the same way. Clear and obvious error is itself an exception clause. The controversy has not shrunk; it has moved off the pitch into the review room and the grey zones of the rulebook. Many assume technology cleans up decisions. Reality runs the other way: technology drags the language of the clause in front of everyone, and when the language is unclear, the question stays unclear.

Vocabulary collision and one confused classifier

Back to that label.

Fine, sanction, infraction, regulation, justified cause — these words look alike in two worlds. In civic law the penalty is called a fine; in sports regulation the penalty is also called a fine; in a transfer file a rule breach is also called a charge. Same words, entirely different institutions, entirely different jurisdictions.

Token-based classification struggles with that difference. The classifier sees penalty, rule and permission inside a document and locks the door to the football room. A pothole and a handball — the same fingerprints of vocabulary in both.

The gap between clauses behaves like the half-space inside a match. The lane between two lines is where a footballer finds the most room; the space between two clauses is where classification makes its mistakes. The resemblance is not accidental. Sports regulation borrowed its grammar from administrative law — committees, hearings, articles, exceptions, appeals.

In my diagrams Foden kept receiving between the lines — a zone no team ever fully occupies, yet a foot lands there before almost every attack. The law's arithmetic behaves the same way: Article 27 fraction IV and Article 28 fraction II create a gap, and real events tend to fall into that gap.

Based on my years of watching matches, one thing holds: the action clusters in the middle of the boundary, and the middle of the boundary is the worst-documented place of all.

What the press box got right

At the 2026 FIFA Under-17 World Cup in Kolkata, I was one of three women in the press box for England's semi-final against Brazil. My pre-match thread had drawn its share of mockery. Rewatching the second half twice, I found Phil Foden had covered 11.3 kilometres, and England's pressing traps had forced 14 Brazilian turnovers. The data contradicted the eye test, and I drew that contradiction onto pitch diagrams.

The old habit applies here too. The first read was not wrong. The reporters who wrote about the pothole did their job; whether a good act can be fined is genuinely something people need to know.

The error was not in their writing. It was in the label placed on top of it. One more thing should not be forgotten: the original report's source field is empty. Beyond two article citations there is no name, no date, no document. The piece would not have scored full marks on a source-verification test even inside its own correct world. Weak sourcing is weak everywhere, whatever the subject.

Mbappe did not arrive; he was already moving before the pass — I write that line when a goal is read as nothing but finishing. A wrong label does not arrive suddenly either; it starts moving inside the data long before the label is attached.

The fix that comes to mind first is the wrong fix

The instinctive reaction: lengthen the keyword list, flag forbidden terms, teach the classifier more words.

The trouble is that the collision is structural, not accidental. Sports regulation borrowed its vocabulary from administrative law, so the words will keep looking alike in both places. Keyword filters cannot break that resemblance; the coarser the filter, the more legitimate documents get quietly trimmed away.

Football itself uses a simple solution, and it is not a word list — it is the memory of the document. FIFA's Transfer Matching System requires both clubs to enter the details of the same transaction in parallel; if the two entries do not match, the International Transfer Certificate is blocked. The power to stop a deal rests not on anyone's good faith but on a process that reconciles two records.

In empty stadiums, I could hear the pressing triggers before the goals — because sound leaked the control system inside the pitch. A data pipeline needs the same kind of hearing: not what the label says, but where the label came from, who attached it, and on what evidence. Those answers belong beside the label.

In my own drawer there was a spreadsheet where, tournament after tournament, I logged pressing triggers. A modern version of that habit is possible: a record that cannot be edited afterwards, only appended to, holding who attached which label, when, and against which piece of evidence. No magic follows from it. What follows is this: the mistake no longer has to be guessed at; it is written down where it happened.

In a transfer window the question sharpens. A new rumour every hour, some pushed by an agent's interest, some by a club's own pressure. What a reader needs is not a longer rumour list but a reliable filter — and the core of that filter is not a club's wish but contracts, clauses, and registered documents.

The real problem is not intelligence. It is memory. Lose the memory of where a thing came from, and every decision becomes a guess.

What to watch from here

Three signals stay on my board.

Sample the documents tagged football and count how many actually contain football. Track which words keep routing files to the wrong address — penalty, rule, permission keep surfacing as suspects. And check the pipeline's own health: entities, time sensitivity, source quality. Empty fields there mean a document has stalled somewhere.

If a pothole and football's governance can be written in the same words, whose memory will we use to verify which word belongs to whom?
