Phase 0 research resolves module placement (problem-management/problems
confirmed dead/unwired, left untouched), Investigation's version-row-per-
attempt shape, the strict investigation->root-cause->solution->
implementation->verification existence chain, why Resolution has no
solutionId FK (matches doc06 exactly), why verification-failure
escalation reuses 003/007's plain HUMAN_ESCALATION transition instead of
adding an eleventh trigger type to 008's already-shipped escalation
rules, the customer-facing route design (reusing 002's inbound trust
boundary rather than fastify.authenticate), and the auto-close sweep
design (the already-defined-but-unused CLEANUP queue, mirroring 008's
breach-detection job).
Phase 1 adds data-model.md, the admin/customer-facing contract, and six
quickstart scenarios covering the full sequential workflow through
customer confirmation, auto-close, and reopen.
