## Why Evelyn currently discards every collected status-index point when it stops, so process restarts lose operational history. Each independently named Evelyn environment needs durable, operator-provisioned append-only storage while Evelyn—not Mission Control—continues to own collection, validation, and publication. ## What Changes - **BREAKING** Require every `EvelynImpl` to have a validated, NFC-normalized instance name that selects its permanent `data/evelyn//status.log` identity. - Reserve normalized instance names atomically and case-insensitively within the JVM until permanent, idempotent close. - **BREAKING** Extend Evelyn lifecycle with permanent close in addition to restartable start/stop. - Strictly validate externally provisioned storage, format version 1, every record, and non-decreasing timestamps before publishing restored history or starting sampling. - Durably append each sampled type-1 status record before publishing it in memory, while isolating individual append failures. - Keep Production and Test storage, lifecycle, and history independent and keep EMC presentation-only. ## Capabilities ### New Capabilities None. ### Modified Capabilities - `evelyn-status-index-history`: Replace process-local disposable history with named-instance storage, strict restore validation, persist-before-publish behavior, and distinct restartable stop versus permanent close semantics. ## Impact The change affects the public Evelyn lifecycle, `EvelynImpl` construction and persistence, and temporary Production/Test composition in `NenjimHubImpl`. Operators must provision each instance directory and versioned `status.log` before startup. EMC, AssetAZ Ticker, Raydium PriceSource, generated Detag sources, and unrelated services remain behaviorally unchanged.
