Move the raw identifier-generation query and the INSERT INTO theses /
INSERT INTO thesis_authors statements out of formulaire.php into two new
Database methods:
generateThesisIdentifier(int $year): string
– counts existing theses for the year inside the open transaction so
concurrent workers cannot produce duplicate YYYY-NNN identifiers.
createThesis(array $data): int
– generates the identifier, INSERTs the thesis row, links the author
via thesis_authors (author_order=1), returns the new thesis ID.
getThesisIdentifier(int $id): string
– fetches the stored identifier for a thesis ID; used by formulaire.php
to reconstruct the upload path (storage/theses/YYYY/YYYY-NNN/).
formulaire.php now calls $db->createThesis([…]) + $db->getThesisIdentifier()
and no longer holds any raw PDO queries for the core thesis insert.
The $pdo local variable (previously $db->getPDO()) is removed entirely.
All four test suites (Unit, RateLimit, Integration, Security) pass.
