Check Cross-Plugin Imports / check (push) Waiting to run
Vorher: Der Migration-Runner trackte Migrationen nur per DATEINAMEN — eine nachtraeglich geaenderte, bereits angewandte Migration blieb unbemerkt (genau die #389-Bugklasse: kaputte Migration wurde gefixt, Runner skippte still, weil der Dateiname schon getrackt war). Fix: - Migration 0148: content_hash-Spalte (SHA-256, 64 Zeichen) in plugin_migrations + Index - PluginMigration-Modell: content_hash-Feld - run_migration: speichert den Hash des angewandten SQL-Inhalts - run_all_migrations: vergleicht bei bereits angewandten Migrationen den Hash und warnt LAUT bei Abweichung (F40 DRIFT-Warnung mit Plugin, Datei, recorded/current-Hash) — Skip bleibt idempotent (kein Deploy- Bruch bei legitimen Reparaturen), aber Drift ist ab JETZT sichtbar Abnahme (Astra): Eine veraenderte angewandte Migration wird erkannt — erfuellt (Drift-Warnung im Runner-Log; #389 haette so beim naechsten Start aufgefallen). Verifikation: Syntax OK, ruff clean, alembic heads = 0148.

"""Add content_hash to plugin_migrations (F40/Astra).
|
|
|
|
The migration runner previously tracked migrations by FILENAME only —
|
|
editing an already-applied migration stayed unnoticed (the #389 bug
|
|
class: a broken migration was fixed, but the runner silently skipped
|
|
it because the filename was already tracked).
|
|
|
|
Now every applied migration records the SHA-256 of its SQL content.
|
|
On subsequent runs the runner compares hashes and logs a loud warning
|
|
when an applied migration was modified (repaired) — the skip stays
|
|
idempotent, but drift becomes VISIBLE.
