Adds the ZONA FEDERAL TIJUANA parser to the statement intake, measured
against 8 pages of real "Zona Federal Marítimo Terrestre" receipts — the
federal maritime-zone occupancy fee the municipality bills on beachfront
lots. Provider read on 8/8, amount on 8/8 (each verified against the
paper), concession clave on 6/8, period on 8/8, deadline on 2/8.
Four things the corpus forced:
- Tijuana bills predial and zona federal from the same treasury: same
header, same Paseo del Centenario address, same ATB-541201 RFC. Every
predial discriminator matches a zona federal page too, so whichever
rule is asked first wins it. The only words exclusive to this layout
are "Marítimo Terrestre", so its brand rule is asked ahead of all
three predial ones — and its structural rule, anchored on the stub's
"Derechos de ocupación", ahead of theirs.
- FEDERAL_ZONE.accountNumber is an amount, not a reference. It holds
DATMEX.zfed, whose 77 values include 246.06, 2369.09, 22653.94 and a
negative -1679, while the concession claves these receipts are keyed
by appear nowhere in the database. Matching on that column could never
hit — and because every row already has a value, the `[field]: null`
guards on learnAccountRefs and on the review blank-service fill would
never fire either, so every page would return to the queue every
bimester forever. The clave moves to meterNumber, joining gas and
Tijuana predial, and the first confirm teaches the match.
- The payable figure is not the printed subtotal. The municipality
rounds to whole pesos and prints the difference on its own "Ajuste Ley
Hacienda Mpal" line (-$0.05 against a 591.05 subtotal, $0.21 against
2,872.79). The "Total a pagar" box carrying the rounded figure sits on
a grey fill and OCR'd on 1 of 8 pages; the SubTotal row read on 8 of
8. So the amount is the rounded subtotal, cross-checked against the
printed box wherever it survives — where it did, it agreed.
- The clave is 2 digits, a letter and 3 digits (12-T -012), not the
cadastral shape, and the letter is kept as printed: toDigits maps D to
0, which turns a real 14-D -014 into 140014. It is printed twice,
which rescued a page whose heading was struck through by the office's
own highlighter — the failure mode behind both missing claves.
Deriving the deadline from the bimester is deliberately not attempted:
it is the 17th of the month after the bimester closes on a current bill,
but four of these eight are late (a $1,000 Multa) and print a
recalculated date, so a derived date would be wrong on exactly the pages
a human most wants to see.
Re-ran the earlier corpora (25 pages: predial Tijuana/Rosarito/Ensenada,
CFE, CESPT, Telnor) through detection to confirm the new rules steal
nothing — all 25 still read as their original provider, including the
five Tijuana predial pages that share the RFC.
