How the thread got there

  • 11 August · Elena opens the thread

    Flags that the customs module will not be tested before 28 September. Proposes nothing yet.

  • 13 August · Andreas

    Argues for holding the date and cutting the scope instead. Three people agree in the next four messages.

  • 16 August · Elena, with the vendor's reply attached

    The vendor confirms their change freeze runs from 25 September to 9 October. Holding the date would mean cutting over with no vendor support. This is the message the decision turns on.

  • 18 August · Marios

    Objects on cost: two extra weeks of parallel running was never budgeted.

  • 19 August · Andreas changes position

    Withdraws the hold-the-date argument and proposes 15 October, keeping Limassol on 28 September. Elena agrees the same afternoon. Nobody contests it after this point.

  • 21 August · Marios

    Withdraws the cost objection once the parallel run is capped at two weeks, and takes the budget action himself.

  • 22–23 August · the thread drifts

    Eleven further messages, all about the rollback rehearsal and the customer notice. No further changes to the decision.

Considered and dropped

Hold 28 September, cut the customs module from the first release

Carried the thread for five days and had three people behind it.

Dropped 16 August — the vendor change freeze covers the cutover window

Move both sites to 15 October

Simpler to run, one date to communicate, one rollback plan.

Dropped 19 August — Limassol has no dependency on the customs module

Parallel run of four weeks rather than two

Raised once, never argued for again after the cost objection.

Dropped 21 August — capped at two weeks to release the budget

Never answered in the thread

Who signs off the rollback, and on what evidence? Asked twice, on 18 and 22 August. Both times the thread moved on to the date instead. There is no owner for this and no criterion written down anywhere.
Christina never acknowledged the customer notice Assigned to her on 20 August, in a message she was copied on but did not reply to. Treat this action as unconfirmed until she says otherwise.
