feat(planning): plans, validation, planner and a restart-safe executor
Plans turn intentions into revisable dependency graphs (migration 0027): objective, assumptions, ordered or dependent steps, capabilities, expected observations, preconditions, risk, estimates, budget, completion criteria, abort conditions and the alternatives considered. - Validation owns structure: acyclic dependencies, registered and unlocked capabilities only, schema-valid parameters, targets that agree with parameters, read-only checks, a closed set of step kinds and internal actions. Model proposals are parsed into the same structure; fields that could carry authority or claim progress are reported as ignored, and an invalid draft is stored as a draft that never runs. - The planner prefers deterministic strategies: a direct action verified by observation, a read-only diagnosis that requests temporary scoped log access with risk and fallback stated, and an escalation that diagnoses and informs the operator instead of repeating a failed action. Failed strategies are not reused; a model is consulted only when none applies. - The executor holds no state in memory: it claims a step with a conditional update, acts only through Invoke and RequestCapability, and records the outcome. Waiting for approval or access forms a subordinate intention and blocks the parent with the reason. Expectations become verification predictions resolved from a read-only observation, so an HTTP-level success is never taken as the outcome; a miss is a prediction error that weakens the supporting belief and triggers reconsideration. Replanning creates a new revision, withdraws open requests of the old one and keeps it as history, within a replan limit. Checks never raise approval prompts. Budgets stop runaway plans. Preconditions skip actions when the world already changed. Dream plans and disabled sandbox minds never act. An interrupted non-idempotent action with no record is blocked for verification instead of repeated; recorded outcomes are adopted. Completed plans are stored as procedural memories; a completed escalation does not count as fulfilling the intention. - Executions and approvals record their origin; minds may withdraw their own pending approval requests; Preview reports a decision without side effects; service.status is allowed by default as a bounded read.
