Release v7.11.5

Changed

• Require session prompts and handovers to state their repository, branch, expected HEAD, named worktrees and date, and verify those preconditions before continuing; mismatches mean the prompt is stale, not that work is lost (#403)
• Make plain method calls the default specifications for pure command, reducer and reactor decisions, adding scenarios where pipelines, validation, constraints or projections contribute proof; distinguish application-assembly Debug wrappers from dedicated spec projects and allow message assertions when exact wording is specified behavior (#449)
